Objective To provide the anatomic basis of transferring the lobe of parotid gland duct for the treatment of dry eye disease. Methods The first interlobar parotid gland duct and zygomatic branch of facial nerve were dissected and observed on parotid gland region of head and face of 5 (10 sides) of adult head specimens. the measurement data was recorded. Results The length of first interlobar duct of superficial parotid was (37. 51±1. 23) mm, the outside diameter of injected parotid duct was (0. 53±0. 15) mm. There was a close ana-tomical relationship between zygomatic branch of facial nerve and first interlobar duct of parotid gland. Conclusion the parotid interlobar duct transposition operation has the reference value in treatment of dry eye desease.

Objective:To explore the mechanism of Jianpi Qingchang Decoction in the treatment of UC by integrating network pharmacology, bioinformatics, molecular docking and experimental verification.Methods:The effective components and targets of Jianpi Qingchang Decoction were obtained from TCMSP database, and UC data sets GSE16879, GSE48958 and GSE75214 were obtained from GEO database, and differentially expressed genes were screened; intersection targets were obtained through Venn diagram, and GO function and KEGG pathway enrichment analysis was performed. An intersection target PPI network was constructed using STRING database and topology analysis was performed; hub genes were screened through lasso regression and the expression consistency of core targets in the dataset was verified through logistic regression. A UC mouse model was established and hub genes were validated.Results:A total of 213 drug targets of Jianpi Qingchang Decoction were obtained, and 499 common intersection targets of GSE16879, GSE48958 and GSE75214 were obtained by differential gene expression analysis. Thirty intersection targets of Jianpi Qingchang Decoction and UC were obtained, mainly acting on IL-17 signaling pathway, TNF signaling pathway, AGE-RAGE signaling pathway in diabetic complications, etc. PPI network topology analysis obtained 7 common intersection targets, including PTGS2, IL-1B, IL-6, MMP9, CXCL8, CCL2 and MMP2. IL-6 and MMP2 were selected as hub genes by lasso regression. Logistics regression analysis showed that IL-6 and MMP2 were risk factors for the disease. Compared with the model group, the expressions of IL-6 and MMP2 mRNA and protein in the colon tissue of the TCM group decreased ( P<0.05), and the morphology of colon tissue was improved compared with the model group. Conclusion:IL-6 and MMP2 are risk factors for UC, the therapeutic effect of Jianpi Qingchang Decoction is to mediate Il-17 signal pathway, TNF signal pathway and AGE-RAGE signal pathway in diabetic complications through the targets of IL-6, and MMP2, thereby treating UC.

OBJECTIVE: To investigate the potential pharmacological mechanism of the seed of Draba nemorosa, and to provide reference for further development, utilization and clinical application. METHODS: Effective components and related target proteins of D. nemorosa were screened and identified by using TCMSP and STRING database. Cytoscape 3.7.0 software was used to construct a visual network of effective components and target proteins for the seed of D. nemorosa, and the network topology analysis was performed. The targeting protein-protein interaction (PPI) network was constructed and analyzed by STRING database and Cytoscape 3.7.0 software. KEGG pathway enrichment of target proteins was analyzed by DAVID bioinformatics resource database. RESULTS: A total of 9 effective components were screened from the seed of D. nemorosa, including quercetin, kaempferol, β-sitosterol, etc. Totally 174 target proteins were obtained, mainly including PTGS2, NCOA2, PGR, etc. Among them, JUN and MAPK1 were core proteins in PPI network. KEGG enrichment pathway included PI3K/Akt signaling pathway, TNF-α signaling pathway, HIF-1 signaling pathway, Toll-like receptor signaling pathway and thyroid hormone signal pathway, etc. CONCLUSIONS: Effective components from the seed of D. nemorosa such as quercetin, kaempferol and β-sitosterol may act on PTGS2, JUN and MAPK1 target proteins through PI3K-Akt signaling pathway and TNF-α signaling pathway, thus exert the effects of purging lung, relieving asthma, promoting edema and reducing edema.
