Objective To compare the curative effect of anti-relfux plastic stent and common plastic stent in treatment of malignant biliary obstruction.Method 22 cases of anti-reflux biliary plastic stent implantation and 30 cases of common bile duct stent implantation from March 2013 to April 2016 were selected as study subject, then compare the operation time, one-time success rate, postoperative pancreatitis, cholangitis, patency, differences in survival situation.Result There was no significant difference between the two groups in the aspects of the operation time, one-time success rate of recent cholangitis after surgery, postoperative pancreatitis (P > 0.05), but there was significant difference between the three aspects of long term patency, cholangitis, survival period (P < 0.05).Conclusion The anti-relfux biliary stent has good long-term curative effect in treatment of malignant biliary obstruction, which worth of further exploration and research.

To explore the regularity of traditional Chinese medicine(TCM) prescriptions for cardio-cerebrovascular diseases,the core drug groups with common therapeutic effects on cerebrovascular diseases represented by stroke and cardiovascular diseases represented by coronary artery disease were extracted,and their consistency and difference in the treatment of different diseases were analyzed.A total of 388 Chinese patent medicines were collected for the treatment of cerebrovascular diseases,cardiovascular diseases and cardio-cerebrovascular diseases.The dominant and recessive patterns of Chinese patent medicines in clinical use were found by "frequency analysis","compatibility analysis" and "network analysis" respectively.According to the findings of the three parts,Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Carthami Flos and Astragali Radix have a high frequency of use in the treatment of brain disease,heart disease and both,with frequent combined medication.Data mining confirmed the core drug combinations for the treatment of cerebral and cardiac vascular diseases,so as to reveal the similarities and differences in the drug use of Chinese medicine for these diseases,and provide a basis for the rational use of traditional Chinese medicine in clinical practice.This analysis also defines a new direction for the future development of prescription combinations for different indications of cerebral and cardiac diseases.
