Objective To observe the effect of GLP-1 on HSP70 expression of rabbit thoracic aortic endothelial cells at high glucose level.Methods Rabbit thoracic aortic endothelial cells were isolated and cultured.Tunnel was used to assay endothelial cells apoptosis.Cell proliferation was analyzed with BUDR.The protein level of HSP70 were detected by Western blot.Results The proliferation of rabbit thoracic aortic endothelial cells cultured under high glucose (33 mmol/L) decreased,(0.54 ±0.06 vs 0.78 ±0.04,P ＜ 0.01).The apoptosis and the protein level of HSP70 increased,(36.43％ ± 6.85％ vs 5.25％ ±0.73％) and (0.94 ± 0.11 vs 0.29 ± 0.03,all P ＜ 0.01).The proliferation of rabbit thoracic aortic endothelial cells (0.62 ± 0.06)in the GLP-1 group increased,the apoptosis ratio (10.13％ ± 1.19％) and HSP70 expression (0.76 ± 0.05) decreased significantly (P ＜ 0.05) compared with high glucose group.Conclusion GLP-1 can ameliorate high-glucose-induced rabbit thoracic aortic endothelial cells apoptosis and promote cell proliferation,attenuating high-glucose-induced level of HSP70 expression through the GLP-1 R-dependent pathways.

Objective To evaluate the efficacy and safety of alemtuzumab in renal transplant recipients treated with induction therapy. Methods Eighty-nine cadaveric renal transplant recipients in our department were randomly divided into experimental group (n = 43) treated with alemtuzumab induction, 15 mg i. v. and control group (n = 46). Main immunosuppressive therapy regimen consisted of steroids, tacrolimus or cyclosporine and mycophenolate mofetil in all recipients. Post-transplant kidney function, acute rejection,infection, DGF, graft survival, lymphocyte counts were recorded within 1 year. ATP values in CD4+ T cells after transplantation was determined by using Cylex ImmuKnow assay. Results There was significant difference in the incidence of biopsy-proven acute rejection, but no significant difference was found in ImmuKnow ATP values during 6 months after transplantation and lymphocyte counts during 3 months, graft survival and the incidence of infections between the two groups. Conclusion Induction therapy with alemtuzumab appeared to be effective in the prevention of acute rejection.

Objective To discuss existing problems in talent team construction; To provide evidence for the government to enact proper strategies based on the analysis of the current situation of TCM practitioners (assistants) distribution in China from quantity, quality and distribution equity. Methods The research is studied through conducting a descriptive analysis of TCM practitioners (assistants) from quantity, education, job titles, ages, and other basic conditions and changes. Gini coefficient was used to evaluate the distribution of TCM practitioners (assistants). Results The quantity of TCM practitioners (assistants) increased by 53.7% from 2010 to 2015. Concerning the quality of personnel, the ratio of the personnel with bachelors degree or above increased from 38.6% to 44.2%, and a slight increase was observed with the personnel with senior title. In terms of age structure, the proportion of the age of TCM practitioners (assistants) under 25 years old, 35 to 59 years old decreased, and the proportion of the age of TCM practitioners (assistants) above 60 years old, 25 to 34 years old increased. From the perspective of equity, there is a difference between the provincial-level administration of human resources distribution. The Gini coefficient as per population distribution was around 0.1, which indicated good equity. From the geographical area configuration, the Gini coefficient was approximately 0.58, which showed high level of disparity. Conclusion There are problems of insufficient quantity, low quality and distribution disparity among regions in TCM practitioners (assistant) in China.

Tanshinones are the bioactive components of the Chinese medicinal herb Salvia miltiorrhiza, while its biosynthetic pathway remains to be characterized. Rapid identification and characterization of the genes correlated to tanshinones biosynthesis is very important. As one of the intermediates of tanshinones biosynthesis, the ferruginol content is relative low in both root and engineered bacteria. It is urgent to construct an efficient system for conversion of miltiradiene to ferruginol to obtain large amount of ferruginol as the substrates for further identifying other downstream genes involved in tanshinones biosynthesis. In this study, we constructed the whole-cell yeast biocatalysts co-expressing miltiradiene oxidase CYP76AH1 and cytochrome P450 reductases (SmCPR1) from Salvia miltiorrhiza, and then characterized it with RT-PCR. After permeabilization, the yeast whole-cell could catalyze turnover of miltiradiene to ferruginol efficiently through single-step biotransformation with a conversion efficiency up to 69.9%. The yeast whole-cell biocatalyst described here not only provide an efficient platform for producing ferruginol in recombinant yeast but also an alternative strategy for identifying other CYP genes involved in tanshinones biosynthesis.
