With the application of drug eluting stent implantation in coronary intervention, the safety and effectiveness of surgical treatment of obstructive coronary artery disease have has been improved, while the postoperative complications still appear to be a concern. In recent years, studies have found that in-stent neoatherosclosis may be an important factor in the development of late stent failure. And with the development of imaging techniques, the in-stent neoatherosclosis after drug eluting stent implantation has been further recognized. However, the mechanism of the development of in-stent neoatherosclosis is still not very clear.

Objective To investigate the correlation between chronic hepatic diseases and small intestinal inflammation.Methods Patients who received capsule endoscopy in The First Affiliated Hospital of Guangdong Pharmaceutical University were divided into groups of liver cirrhosis,non-alcoholic fatty liver disease(NAFLD),chronic hepatitis and non-hepatic disease according to clinic data from August 2011 to August 2015.The severity of small intestinal mucosal inflammation was graded according to Lewis Scoring system and incidence of small intestinal lesions in different groups and Lewis scores were compared.The liver function was also graded with liver noninvasive scoring systems.Then the correlation between liver function damage and small intestinal lesions was investigated.Results A total of 338 cases were enrolled in the study,including 25 cases of liver cirrhosis,47 cases of NAFLD,20 cases of chronic hepaitis and 246 cases of non-hepatic disease.There were 22 (88.0％),36 (76.6％),12 (60.0％) and 78 (31.7％) cases with lesions in small intestine in the four group respectively with significant differences(P＜0.001).Rate of small intestinal villi edema was significantly higher in liver cirrhosis group,NAFLD group,chronic hepatitis group than that in non-hepatic disease group(all P＜0.017).Small intestinal villi edema was found mainly in the upper and one third of middle parts in small intestine (P =0.033).Lewis scores of liver cirrhosis group (190.80±228.42)and NAFLD group(125.38± 191.31) were higher than those of non-hepatic disease group (42.91±97.69,P=0.021,P =0.034).Forns score,FIB-4 score,NAFLD-FS score and Child-Pugh score were positively correlated with Lewis score (correlation coefficient:0.247,0.244,0.223,0.284respectively,all P＜0.001).Conclusion Chronic hepatic diseases such as liver cirrhosis,NAFLD,chronic hepatitis might be risk factors for small intestinal mucosal inflammation,and the severity of chronic hepatic diseases may be positively correlated with that of small intestinal mucosal lesions.

The student majoring in Medical Biological Technique will be mainly engaged in the practical work of biological technique industry after graduation in the future.In order to bind the theories on the practical biological techniques in designs of contents and roundly improve students' practical ability in classes as well as enriching the communication among students,our college offers an immunologic techniques experiment classes with 36 hours per semester,which has also undergone a reasonable project teaching innovation. This proved to result in a satisfactory outcome in improving the students' practical a

Objective To explore the changes of cell proliferation and differentiation of neural stem cells induced by fasudil treatment,and to primarily study the mechanism in C17.2 mice.Methods C17.2 cells were cultured in vitro; 5,25,50 and 100 μmol/L fasudil were given to the cells,respectively,for 24 h,and cells in the blank control group were given the same volume of culture medium.The changes of cell morphology were observed under a phase-contrast microscope; cell viability and cell necrosis rate were determined by MTT assay and lactate dehydrogenase (LDH) assay,respectively.Western blotting was applied to detect the expression levels of neural markers (nestin,glial fibrillary acidic protein [GFAP],double cortisol [DCX],microtubule-associated protein-2 [MAP-2]),and Notch Ⅰ and Hes 1 proteins in the notch signaling in cells from the 100 μmol/L fasudil treatment group and blank control group.Immunofluorescence staining was used to detect the nestin and GFAP expressions in the C 17.2 cells.Results As compared with that in the blank control group,the cell viability in the 50 and 100 μmol/L fasudil treatment groups was significantly decreased; that in the 100 μmol/L fasudil treatment group was significantly lower than that in 50 μmol/L fasudil treatment group (P＜0.05); LDH assay showed no significant difference of cell necrosis among the five groups (P＜0.05).Western blotting indicated that 100 μmol/L fasudil treatment group had significantly decreased nestin expression,significantly elevated DCX,MAP-2 and GFAP expressions,and statistically decreased expression levels of Notch 1 and Hes 1 as compared with blank control group (P＜0.05).Immunofluorescence staining indicated that the percentage of nestin positive cells was markedly decreased,the percentage of GFAP positive cells was significantly increased in the 100 μmol/L fasudil treatment group as compared with those in the blank control group (P＜0.05).Conclusion Fasudil treatment could inhibit the proliferation of C17.2 cells and promote them differentiate into neuronal and glial cells via decreasing the expression level of Notch signaling.
