diseases and cancer [5ndash12] and these problems represent asignificant social and economic burden

Based on systems biology and pharmacology networkpharmacology leverages network analysis and screens nodesto identify proteins critical to a disease for drug design[13 14] Network pharmacology can be used to investigatesynergism of multicomponent drugs to identify high efficacyand low toxicity agents with multiple targets [15 16] Chineseherbal formulas often have numerous targets and are com-prised of many substances so network pharmacologymay beuseful for studying traditional Chinese medicine [17 18]

Bufei Huoxue (BFHX) capsules contain three commonChinese herbal products Astragalus radix paeoniae rubraand Psoralea corylifolia and have been approved by the ChinaFood and Drug Administration (Number Z20030063) forthe treatment of pulmonary heart disease Clinical studiessuggest that these compounds improve pulmonary ventila-tion function and reduce silicosis and lung inflammation[19ndash21] Thus we studied BFHX capsules and PM25-relatedrespiratory disease using a network pharmacology platformThe effects of BFHX capsules on PM25-induced pulmonaryinflammation were evaluated and the underlying mecha-nisms of action were investigated in mice

2 Materials and Methods

21 PM25-Related Diseases PM25-related diseases wereidentified using Polysearch System (httpwishartbiologyualbertacapolysearchindexhtm) a web-based text-min-ing system for extracting relationships among human dis-eases genes drugs and metabolism PM25-related dis-eases were searched and extracted statements were manuallyscreened According to 119885-values the top 10 diseases wereselected for further study

22 Prediction of Disease Pathways and BFHX Targets Alltarget genes or proteins for each BFHX component (Astra-galus radix paeoniae rubra and Psoralea corylifolia) wereobtained using Polysearch and diseases were selected frompredictions based on keywords Targets were networked andvisualized using Cytoscape 321 software Drug- and disease-related targets were merged using Merge to screen key targetproteins

23 PM25 Mouse Model and Drug Intervention

231 PM25 Sampling and Suspension Preparation PM25samples were collected from three sites in Beijing in thesummer and winter seasons of 2011 and 2012 The three siteswere a roadside site located 2m from the curb of the North4th Ring Road an urban site on the campus of Tsinghua Uni-versity and a rural site situated in the countryside of MiyunSampling was conducted by Anderson particulate samplerHBL-GUV (Thermo Fisher Waltham MA) equipped witha PTFE membrane for two consecutive weeks [22] At theend of sample collection the PTFE membrane carryingPM25 was cut into 1 times 3 cm pieces and placed in ultrapurewater Particles were eluted three times under ultrasonic

oscillation 40min each Liquid containing the particulatematter was filtered through six layers of sterile gauze andcentrifuged at 12000 rpm at 4∘C for 30min The lower layerof the suspension was collected and vacuum-freeze dried toyield PM25 particles which were then stored at minus20∘C Tomake a stock solution PM25 particles were weighed andsuspended in saline at the desired concentrations after beingultrasonicated for 15min and sterilized Samples were storedat 4∘C Detailedmethods can be found in related papers by usand other authors [23 24]

232 Drugs BFHX capsules were provided by Lei Yun ShangPharmaceutical Limited (Suzhou Jiangsu China) The drypowder was taken from the capsules and suspended indistilled water The mixture was stored at 4∘C

233 Animals Adult female ICR mice (Beijing HFKBiotechnology Co Ltd China 22ndash26 g) were housed inseparate cages with food and water freely available understandard laboratory conditions of 22ndash28∘C and relativehumidity of 50ndash60 with a 12 h light12 h dark cycle Animaltreatment and maintenance were performed in accordancewith requirements of and the study protocol was approvedby the institutional animal care and use committee at theChina-Japan Friendship Hospital in Beijing (Permit 150202) All efforts were made to minimize suffering

Sixty ICR female mice were randomized into 3 groupsnormal controls PM25 exposure and BFHX interventiongroups (119873 = 20group) Controls were given an intranasalinstillation of saline (20120583lmouse) on days 1 8 15 and 22ThePM25 exposure group was given an intranasal instillation ofPM25 suspension (40mgkg 20 120583lmouse) on days 1 8 15and 22 and each received oral saline (02mlmouseday) fromdays 1 to 22 The BFHX intervention group was treated aswas the PM25 exposure group except that BFHX (082 gkg02mlmouseday) instead of saline was given daily Animalswere sacrificed 48 h after the last treatment

24 Lung Function Mice were anesthetized with 2 pento-barbital (04ml40 g ip) and secured in a supine position tobe orotracheally intubated Then mice were transferred toa plethysmography platform and lung function analysis wasmeasured lung include inspiratory resistance (RL) expira-tory resistance (RE) dynamic lung compliance (Cdyn) andpeak expiratory flow (PEF) using an AniRes2005 apparatus(Beilanbo Science and Technology Co Ltd Beijing China)

25 Lung Histology Mice were sacrificed and subjected tothoracotomy with lung resectionThe left lung lobe was fixedin 10 formalin for 24 h and then dehydrated embeddedin paraffin and sectioned Sections were stained with hema-toxylin and eosin (HampE) according to the routine stainingmethod and observed under an optical microscopeThe rightlung lobe was homogenized for molecular studies

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

which may improve fibrosis and improve lung function(Figure 6)

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

Based on systems biology and pharmacology networkpharmacology leverages network analysis and screens nodesto identify proteins critical to a disease for drug design[13 14] Network pharmacology can be used to investigatesynergism of multicomponent drugs to identify high efficacyand low toxicity agents with multiple targets [15 16] Chineseherbal formulas often have numerous targets and are com-prised of many substances so network pharmacologymay beuseful for studying traditional Chinese medicine [17 18]

Bufei Huoxue (BFHX) capsules contain three commonChinese herbal products Astragalus radix paeoniae rubraand Psoralea corylifolia and have been approved by the ChinaFood and Drug Administration (Number Z20030063) forthe treatment of pulmonary heart disease Clinical studiessuggest that these compounds improve pulmonary ventila-tion function and reduce silicosis and lung inflammation[19ndash21] Thus we studied BFHX capsules and PM25-relatedrespiratory disease using a network pharmacology platformThe effects of BFHX capsules on PM25-induced pulmonaryinflammation were evaluated and the underlying mecha-nisms of action were investigated in mice

2 Materials and Methods

21 PM25-Related Diseases PM25-related diseases wereidentified using Polysearch System (httpwishartbiologyualbertacapolysearchindexhtm) a web-based text-min-ing system for extracting relationships among human dis-eases genes drugs and metabolism PM25-related dis-eases were searched and extracted statements were manuallyscreened According to 119885-values the top 10 diseases wereselected for further study

22 Prediction of Disease Pathways and BFHX Targets Alltarget genes or proteins for each BFHX component (Astra-galus radix paeoniae rubra and Psoralea corylifolia) wereobtained using Polysearch and diseases were selected frompredictions based on keywords Targets were networked andvisualized using Cytoscape 321 software Drug- and disease-related targets were merged using Merge to screen key targetproteins

23 PM25 Mouse Model and Drug Intervention

231 PM25 Sampling and Suspension Preparation PM25samples were collected from three sites in Beijing in thesummer and winter seasons of 2011 and 2012 The three siteswere a roadside site located 2m from the curb of the North4th Ring Road an urban site on the campus of Tsinghua Uni-versity and a rural site situated in the countryside of MiyunSampling was conducted by Anderson particulate samplerHBL-GUV (Thermo Fisher Waltham MA) equipped witha PTFE membrane for two consecutive weeks [22] At theend of sample collection the PTFE membrane carryingPM25 was cut into 1 times 3 cm pieces and placed in ultrapurewater Particles were eluted three times under ultrasonic

oscillation 40min each Liquid containing the particulatematter was filtered through six layers of sterile gauze andcentrifuged at 12000 rpm at 4∘C for 30min The lower layerof the suspension was collected and vacuum-freeze dried toyield PM25 particles which were then stored at minus20∘C Tomake a stock solution PM25 particles were weighed andsuspended in saline at the desired concentrations after beingultrasonicated for 15min and sterilized Samples were storedat 4∘C Detailedmethods can be found in related papers by usand other authors [23 24]

232 Drugs BFHX capsules were provided by Lei Yun ShangPharmaceutical Limited (Suzhou Jiangsu China) The drypowder was taken from the capsules and suspended indistilled water The mixture was stored at 4∘C

233 Animals Adult female ICR mice (Beijing HFKBiotechnology Co Ltd China 22ndash26 g) were housed inseparate cages with food and water freely available understandard laboratory conditions of 22ndash28∘C and relativehumidity of 50ndash60 with a 12 h light12 h dark cycle Animaltreatment and maintenance were performed in accordancewith requirements of and the study protocol was approvedby the institutional animal care and use committee at theChina-Japan Friendship Hospital in Beijing (Permit 150202) All efforts were made to minimize suffering

Sixty ICR female mice were randomized into 3 groupsnormal controls PM25 exposure and BFHX interventiongroups (119873 = 20group) Controls were given an intranasalinstillation of saline (20120583lmouse) on days 1 8 15 and 22ThePM25 exposure group was given an intranasal instillation ofPM25 suspension (40mgkg 20 120583lmouse) on days 1 8 15and 22 and each received oral saline (02mlmouseday) fromdays 1 to 22 The BFHX intervention group was treated aswas the PM25 exposure group except that BFHX (082 gkg02mlmouseday) instead of saline was given daily Animalswere sacrificed 48 h after the last treatment

24 Lung Function Mice were anesthetized with 2 pento-barbital (04ml40 g ip) and secured in a supine position tobe orotracheally intubated Then mice were transferred toa plethysmography platform and lung function analysis wasmeasured lung include inspiratory resistance (RL) expira-tory resistance (RE) dynamic lung compliance (Cdyn) andpeak expiratory flow (PEF) using an AniRes2005 apparatus(Beilanbo Science and Technology Co Ltd Beijing China)

25 Lung Histology Mice were sacrificed and subjected tothoracotomy with lung resectionThe left lung lobe was fixedin 10 formalin for 24 h and then dehydrated embeddedin paraffin and sectioned Sections were stained with hema-toxylin and eosin (HampE) according to the routine stainingmethod and observed under an optical microscopeThe rightlung lobe was homogenized for molecular studies

26 Masson Staining Lung collagen content was quantifiedwith Masson trichrome staining Paraffin sections were firstdewaxed followed by washing with tap and then distilled

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

which may improve fibrosis and improve lung function(Figure 6)

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

which may improve fibrosis and improve lung function(Figure 6)

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

significantly decreased inspiratory (119901 lt 001) and expiratoryresistance (119901 lt 005) and increased dynamic lung complianceand maximum forced expiratory flow (119901 lt 001) in PM25mice Thus BFHX intervention significantly improved lungfunction and reduced airway resistance and increased airwaycompliance (Figure 6) in PM25 mice

43 Effect of BFHX on PM25-Induced Pulmonary Histopa-thology in Mice In the normal group and the BFHX groupbronchial mucosa and bronchial wall structures were intactand alveolar structural integrity was intact Some inflam-matory cells had infiltrated alveolar spaces but there waslittle interstitial inflammation and lung capillary structures

were intact with no bleeding Figure 7 shows that com-pared with the normal group and the BFHX group PM25exposure caused histological injury such as widened alveolarsepta capillary congestion and minor hemorrhages of smallairways BFHX treatment significantly reduced histologicalinjury and reduced congestion and hemorrhage of smallairways and recruitment

44 Effect of BFHX on Lung Collagen Deposition in MiceControls had collagen deposition in many small airways andfibrosis was noted around the vascular wall PM25-exposedlung tissues had thickened airways with obvious collagendeposition smaller alveoli with wider septa and obvious

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

which may improve fibrosis and improve lung function(Figure 6)

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

which may improve fibrosis and improve lung function(Figure 6)

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

5 Discussion

Leveraging bioinformatics and computer science networkpharmacology offers an effective approach to studying drugand disease interactions by constructing a ldquomolecular-target-diseaserdquo relationship [17] Using a network pharmacologyplatform we confirmed that PM25 exposure contributed torespiratory and heart disease The respiratory system wasinitially injured but the circulatory and neural systems couldbe subsequently involved via multipathological pathways

Data show that BFHX targets many genes related to PM25respiratory diseases such as asthma lung cancer COPDpneumonia and pulmonary embolism in complicated anddiverse ways BFHX regulates expression of inflammatoryfactors (TNF-120572 IL-1120573 IL-4 IL-6 and IL-10) and immuneregulation (CD4+ and CD8+ cells) and may be involved inadjusting related signaling pathways (BCL2 STAT3 and P38)in regulating cell proliferation chemotaxis and apoptosis(Figures 1ndash5)

Different sized particles can damage different parts ofthe respiratory system Fine particulate matter (1ndash25 120583mdiameter PM1ndash25) can enter bronchi and the deeper res-piratory tract Those of 01ndash1120583m diameter (PM01ndash1) candeeply penetrate the lung and ultrafine particles (PM01)can penetrate alveoli and enter the circulation [25] PM25can reduce lung function and induce asthma episodesbronchitis lung cancer and other respiratory diseases [26]Animal models of lung injury can be established by nasallyinstilling PM25 suspensions and in mice this manifests aslung tissue and small airway damage as well as alveolarand pulmonary interstitial inflammation BFHX repairedairway damage and improved lung function in these modelsand decreased airway resistance and increased lung com-pliance Data show that BFHX can improve lung functionreducing PM25-induced lung injury and promoting heal-ing BFHX also significantly reduced collagen deposition

TNF-120572 and IL-1120573 are important proinflammatorycytokines that activate and recruit inflammatory cellsenhance inflammatory response [27 28] and stimulateproliferative response of smooth muscle cells and fibroblastin the airway resulting in remodeling [29 30] IL-4 is agrowth factor secreted by T cells and IL-6 produced byresponses of mononuclear macrophages endothelial cellsfibroblasts and other cells to IL-1 and TNF-120572 [31ndash33]contributes to immune defenses and can enhance airwayinflammation IL-10 is an immunomodulatory cytokine andis made mainly by activated monocytes lymphocytes andepithelial cells A high level of IL-10 was produced afterdamage [34 35] and IL-8 was significantly increased in localinflammation serum and body fluid because of infectionand some autoimmune diseases [36 37] BFHX significantlydecreased TNF-120572 IL-1120573 IL-6 IL-10 IL-4 and IL-8 in lungof PM25 mode mice (Figures 10 and 11)

HMGB1 is widely distributed in the lymph brain liverlung heart kidney and other tissues Under stimulation ofIL-1 and TNF-120572 HMGB1 can be secreted into the extra-cellular space to promote cytokine production and extend

inflammation [38] Recent studies indicate that activationof HMGB1 signaling is associated with acute lung injuryasthma pulmonary fibrosis and other respiratory diseasesand HMGB1 expression is correlated with respiratory diseaseseverity [39] BFHX alleviated inflammation and decreasedsubsequent injury to lung tissue of PM25 model mice(Figure 9)

KGF is a cytokine synthesized by 120574120575T cells and stimulatesepithelial cell proliferation differentiation andmigration andpromotes mucosal repair maintenance of mucosal integrityKGF stimulates synthesis storage and secretion of pul-monary surfactant in type II alveolar epithelial cells (AECII) reduces alveolar surface gas-liquid surface tension andprevents excessive expiratory alveolar collapse and over-inspiratory expansion to maintain alveolar shape KGF secre-tion is increased promoting tissue repair but KGF is reportedto be associated with early growth of mesothelial cellsafter asbestos exposure which contributes to lung fibrosis[40] IL-17 a powerful proinflammatory factor is a majorcytokines synthesized by 120574120575Tcells and reflects their biologicalactivity to a certain extent [41] 120574120575T cells are importantduring the transition from innate immune cells to acquiredimmune cells So BFHX may control 120574120575T cell activity to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to

sIgA is a human IgA exocrine antibody found in themucosa of respiratory gastrointestinal and urogenital tractsand is a first line of defense against bacterial and viraladsorption and colonization on epithelial cell surfaces [6]Respiratory tract infections pathogenic microbial invasionand adhesion to the epithelium stimulate a local mucosalimmune response by increasing synthesis and secretionof sIgA Data show that in PM25 mice BFHX reducedsIgA secretion and reduced airway damage suggesting that

BFHXameliorated localmucosal inflammation (Figure 11) Insummary our data suggest that BFHX reduced pathologicalresponses induced by PM25 via regulation of inflammatorymediators in mouse lungs

6 Conclusion

We noted that PM25 could stimulate lung tissue inflamma-tory factors promote generation of secretory immunoglob-ulin and KGF and cause collagen fiber deposition in lungtissue BFHXmodified the respiratory tract mucosal immuneresponse and inhibited secretion of immunoglobulin to
