Objective To observe the expression and distribution of myofibroblasts in the healing process of bile duct and discuss its function and significance in the process of iatrogenic biliary stricture formation. Methods A model of trauma-repair of bile duct in the dog was made . The anastomosis tissues on week 1,3 and month 3,6 after operation were studied with TEM and immunohistochemical SP staining of SMA. Results Myofibroblasts functioned actively and lasted for the whole process, extracellular matrix overdeposited. SMA staining was observed in myofibroblasts and highly expressed from 1 week to 6 months after operation. The consequence easily leaded to scar contracture and anastomoctic stenosis. Conclusion Myofibroblast is the main cause of scar contracture of bile duct.

OBJECTIVE: To provide a theoretical basis for the development of the following products of Coptis chinensis- Zingiber ojjicinale couplet medicine (“Coptis chinensis-Zingiber ojjicinale” for short) prescription. METHODS: The prescriptions containing Coptis chinensis-Zingiber ojjicinale were collected from the Dictionary of TCM Prescription and input into TCM inheritance support platform software (V2.5) to establish the database. The frequency of major diseases and compatibility medicinal materials were analyzed statistically. The core combination of medicinal materials in the prescriptions containing Coptis chinensis-Zingiber ojjicinale were analyzed statistically with association rule Apriori algorithm (support degrees were 15%, 20%, 25%, confidence was 0.90). Top 2 main diseases in the list of frequency, compatibility medicinal materials for dispelling internal cold and medicine for clearing heat with highest compatibility frequency were selected and analyzed in respect of prescription rules. RESULTS: A total of 492 prescriptions containing Coptis chinensis-Zingiber ojjicinale were screened, 9 kinds of major diseases (frequency≥15), such as dysentery, diarrhea, accumulation, fullness. There were 21 commonly used compatibility medicinal materials (frequency≥55), including Angelica sinensis-Panax ginseng, Magnolia officinalis, Aconitum carmichaelii, Scutellaria baicalensis, etc. There were 19 commonly used medicinal materials combinations, including Coptis chinensis-Zingiber ojjicinale-Panax ginseng, Coptis chinensis-Zingiber ojjicinale- Magnolia officinalis, Coptis chinensis-Zingiber ojjicinale-Angelica sinensis. There are 5 kinds of core medicinal materials commonly used in treating dysentery with Coptis chinensis-Zingiber ojjicinale,and 9 kinds of core medicinal materials for treating dysentery. There are 8 kinds of core medicinal materials in Coptis chinensis-Zingiber ojjicinale compatible with medicine for dispelling internal cold Aconitum carmichaelii prescription.and 7 core medicinal materials in compatible with medicine for clearing heat Scutellaria baicalensis prescription. CONCLUSIONS: The major diseases treated with prescriptions containing Coptis chinensis-Zingiber ojjicinale are mainly digestive tract diseases. It can treat different diseases being compatible with different medicinal materials, this study aslo can provide theoretical basis for the development of subsequent products.
