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.

Objective To analyze the nucleotide sequences and genetic polymorphisms of UL138 gene of low passage human cytomegalovirus ( HCMV) strains isolated from infants in Guangzhou province. Methods The low passage strains of HCMV were isolated from urine samples of 10 infants with HCMV in-fection in Guangzhou province and identified by multiplex PCR.The UL138 genes were amplified, cloned and identified with sequencing.The sequences were analyzed together with the homologous sequences of 10 clinical isolates published in GenBank.The sequences of UL138 genes were analyzed by using bioinformatics softwares for investigation of the post-translational modification sites, isoelectric points and second structures of UL138 proteins.Results Three low passage strains of HCMV ( D2, D3 and D52) were isolated from in-fants with congenital HCMV infection.The complete sequences of UL138 genes of the three strains were sub-mitted to GenBank after sequencing identification with the GenBank accession numbers of DQ180375, DQ180387 and DQ180359, respectively.The UL138 gene sequences of the three clinical isolates were high-ly conservative.Among the 841 base pairs of the UL138 gene sequences, mutations were identified in 16 sites with base substitution, no any insertion and deletion mutation was found.The 16 mutations resulted in 7 amino acid changes.No additional or deleted sites were found with regard to the post translational modifi-cation sites of UL138 protein in all clinical isolates except the Toledo strain.The isoelectric point of UL138 protein was 6.51 for all clinical isolates.Conclusion The UL138 genes and the deduced amino acid se-quences of HCMV strains isolated from infants in Guangzhou were highly conservative, regardless of the poly-morphism of UL138 gene.This study paved the way for further investigation on HCMV infection and its path-ogenic mechanism.
