Objective To explore the protective effect of atorvastatin on irradiated endothelium and the thrombomodulin(TM)expression.Methods Cultured human coronary artery endothelial cells(HCAEC)and human umbilical vein endothelial cells(HUVEC)were treated by atorvastatin at the final concentration of 10 μmol/ml for 10 min,and then irradiated with 2 and 25 Gy.Cell cycles status and TM expression were quantitatively measured by flow cytometry 24 hours after irradiation.Protein C activation in endothelial cells was also assessod.Results After administration with atorvastatin for 24 h,the TM expression increased by 77%,59% and 61% in normal control group,2 Gy group and 25 Gy group,respectively(t=27.395,26.420,58.065;P=0.000).The protein C levels decreased by 23% and 34% compared with the normal group post-irradiation to 2 and 25 Gy,but increased by 79% and 76% compared with the irradiated control group after administration with atorvastatin.The rates of cell apoptosis decreased by 6% and 16% in 2 Gy and 25 Gy groups,respectively after administration with atorvastatin for 24 h(t=4.178,17.863;P=0.000).Conclusions Atorva statin can protect endothelia cell from irradiation-induced apeptosis by increasing TM expression and protein C activation.

Objective To investigate the expression of CD40-CD154 co-stimulatory pathway in peripheral circulation and intestinal mucosa in patients with inflammatory bowel disease (IBD),the difference between the expression of CD40-CD154 in patients with IBD and that in healthy controls,and the correlation between CD40-CD154 levels and disease activity. Methods A total of 62 patients with Crohn's disease (CD),64 patients with ulcerative colitis (UC) and 56 healthy controls were enrolled. Enzyme-Linked Immuno Sorbent Assay (ELISA),SYBR-green real time PCR and immunohistochemical assay were respectively applied to evaluate expression of CD40-CD154 in plasma,mononuclear cells of peripheral blood and intestinal mucosa. Results Levels of CD40 (P=0. 000) and CD154 (P=0. 001) in plasma,mononuclear cells of peripheral blood and intestinal mucosa were significantly higher in patients with CD and UC than in healthy controls. However,no correlation between disease activity and CD40-CD154 expression in peripheral circulation or intestinal mucosa was detected (P ＞ 0. 05 ). Conclusion CD40-CD154 pathway activation is found in plasma,peripheral blood mononuclear cells and intestinal mucosa in patients with IBD,but is not correlated with disease activity.

Assessment mode is a bottleneck in medical education reform nowadays.Although traditional assessment tools,such as written examination,are still widely used in medical education assessments,they have obvious limitations.With the enhancement of requirements in physicians' abilities,assessments on some basic abilities of physicians are still insufficient.The United States and Europe not only focus on the curriculum reform but also the development of appropriate assessment tools,therefore,some new assessment tools are invented.These assessment tools are applicable to the formative assessment and are student-centered,being able to promote the development of education and provide new options for medical education assessments.

OBJECTIVETo explore the prediction of the site for microsurgical vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (OA).

METHODSThis study involved 56 infertile men with confirmed OA whose obstruction was suspected to be in the epididymis. Based on their medical history and results of preoperative physical examination and ultrasonography, we predicted the sites for VE. We performed surgical scrotal exploration for the status of epididymal obstruction, conducted palpation and microscopic observation for the epididymal tubules to be anastomosed, and finally decided on the sites for VE by making sure of the presence of motile sperm in the epididymal fluid of the patients. After surgery, we followed up the patients for the rate of pregnancy.

RESULTSAll the patients received bilateral scrotal ultrasonography and surgical scrotal exploration, totaling 112 procedures, including 98 VE procedures. The accuracy rate of the predicted sites for VE was 80.5% (153/190) by medical history and physical examination, 80.3% (90/112) based on the results of ultrasonography, and 87.4% (90/103) according to the first selected epididymal tubules. Of the 28 patients followed up for more than 12 months, motile sperm were found in 19 (67.9% ) at 2 to 12 months and spontaneous pregnancies were achieved in 10 (35.7%), all with the anastomotic sites in the corpus or cauda.

CONCLUSIONMedical history and physical examination contribute to the selection of anastomotic sites and non-invasive scrotal ultrasonography is effective and practical for positioning epididymal obstruction. The epididymal tubules with motile sperm for anastomosis could be easily obtained from the most dilated ones in indurated epididymides.

Objective To investigate the expression of CD27-CD70 co-stimulatory pathway in peripheral circulation and intestinal mucosa of patients with inflammatory bowel disease, and to find the difference between the expression of CD27-CD70 in patients with inflammatory bowel disease and in healthy controls. Methods A total of 62 patients with Crohn's disease, 64 patients with ulcerative colitis and 56 healthy controls were enrolled. Enzyme-linked immunosorbent assay was applied to evaluate plasma CD27-CD70 protein expression in patients with inflammatory bowel disease and healthy controls. SYBR-green real time PCR was applied to access CD27-CD70 mRNA expression in peripheral blood mononuclear cells in patients with inflammatory bowel disease and healthy controls.And CD27-CD70 protein expression in intestinal mucosa was determined by immunohitochemistry.Results Plasma levels of CD27 (P=0. 025) and CD70 (P=0. 000) were significantly higher in patients with Crohn's disease than in healthy controls. However, CD27 (r= 0. 055, P= 0. 673) and CD70 (r= 0. 024, P = 0. 852) were not significantly associated with endoscopic disease activity in patients with Crohn's disease. Similarly, CD27 (P=0. 001) and CD70 (P=0. 000) were significantly higher in patients with ulcerative colitis than in healthy controls. And CD27 (r=0. 077, P=0. 547)and CDT0 (r=0.021, P=0. 869) were not significantly associated with endoscopic disease activity in patients with ulcerative colitis. Moreover, CD27 and CD70 mRNA expression in peripheral blood mononuclear cells were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000), and immunostaining indicated that CD27 and CD70 expression in intestinal mucosa were significantly higher in patients with Crohn's disease and ulcerative colitis than in healthy controls (all P=0. 000). Conclusions CD27-CD70 pathway activated in plasma, peripheral blood mononuclear cells and intestinal mucosa of patients with inflammatory bowel disease. However,plasma levels of CD27 and CD70 can not reflect endoscopic disease activity.
