Objective:To study the influence of gonadal hormones on the function of lymphocytes of SLE patients through detecting the expression of estrogen receptor alpha(ER?) and the function of peripheral blood lymphocytes of SLE patients.Methods:Blood samples of 33 SLE patients and 31 normal controls were collected.Estradiol(E2) and testosterone (T) concentration in peripheral blood were detected by ELISA,the proliferating reaction of T lymphocyte stimulated by ConA were detected by methyl thiazolyl tetrazolium (MTT) assay and the expression of estrogen receptor alpha(ER?)mRNA of peripheral blood mononuclear cells (PBMCs),T lymphocytes and B lymphocytes were detected by RT-PCR.Results:Compared with normal control,the stimulating index of T lymphocyte proliferation decreased(P

Glycogen synthase kinase-3β( GSK-3β) is a serine-threonine kinase,which was originally identified as a key regula-tor of glycogen metabolism. In nervous system, GSK-3β partici-pates in many central and peripheral nervous system physiological processes through transcription,cell proliferation and differentia-tion. The abnormal activity of GSK-3βinduces downstream signa-ling molecules and gene expression abnormalities,which are in-volved in some neuropsychiatric disorders such as schizophrenia, bipolar disorder,Alzheimer's disease,and pain. In recent years, lots of basic and clinic researches focus on GSK-3β,which might gradually become critical theraptic target of many diseases. The article mainly reviews the mechanisms involved in abnormal acti-vation of GSK-3β related neuropsychiatric disorders.

Objective To evaluate the effect of health education on blood glucose level in patients undergoing renal transplantation.Methods Two hundred and four patients who underwent renal transplantation were randomly assigned to the control group(n =102)and the intervention group(n =102).Participants of the control group received traditional health education,and those in the intervention group received general health education.Food intake,physical exercises.disease-related knowledge,treatment satisfaction,fasting plasma glucose and 2 h blood glucose were assessed at 6 months.Results Daily diet,physical exercises,disease-related knowledge,treatment satisfaction,and blood glucose control were significantly improved in the intervention group(all P＜ 0.05).Conclusion General health education may contribute to the control of hyperglycemia and improve long-term survival of renal transplantation receivera.

Objective To establish the norm of occupational stress on the nurse in China. Methods Used stratified random cluster sampling,a total of 3091 nurses in 21 from China' s eastern,central and western parts of three regional hospitals, hospital were tested by Chinese nurse stressor scale (CNNS). Results ①The total norms for the CNNS and each factor are established. ②Descriptive statistics for CNSS for different regions samples, different working year' s samples,different marital status samples,different titles samples,different age's samples, different education background samples and different work nature samples were modulated. Conclusion The norm established can basically represent the occupational stress on nurses in China.

Objective To investigate the therapeutic effect and safety of the clip with the flossmethod during endoscopic submucosal dissection for early gastric angle cancer. Methods A total of 27 gastric angle lesions diagnosed as early gastric cancer were treated by ESD. They were randomized to two groups, routine ESD group and clip with the flossgroup. The procedure time, complication events, en-block resection rate and complete resection rate were compared between the two groups. Also,the learning time was divided to two stages and the learning curve was studied according to the resected specimen areas per minute. Results The en block rate was 85. 7%(12/14) in the routine ESD group and 100. 0%(13/13) in the clip with the floss group. The procedure time in the clip with the flossgroup was significantly less than that in the routine ESD group (the median time 30 min VS 40 min, P =0. 011) . Perforation and the post operative bleeding did not occur in either group. The ESD learning curving during the first learning period and the mean resected specimen (area/min) in theclip with the floss group were larger than routine ESD group(30±6 mm2/min VS 20±5 mm2/min,P=0. 01). However, no difference presented during the second learning period between the two groups. Conclusion Clip with the flossmethod during endoscopic submucosal dissection for early gastric angle cancer as a novel procedure is safe, efficacious and worthy to recommend to beginning learners.

Objective:To investigate the expression of aromatase of renal tissue in systemic lupus erythematosus(SLE)model mice.Methods:BALB/c mice were induced SLE with homologuous splenic cell activated with ConA after being ovariectomized,and in the same time administered different doses of benzestrofol.E2 in peripheral blood and renal tissue was detected by ELISA and the expression of mRNA of aromatase in renal tissue was detected by RT-PCR in the 4th,6th,8th and 10th weeks.Results:The level of E2 of peripheral blood and renal tissue of SLE model mice became higher as benzestrofol exogenously administered heightened.Compared with control mice,the level of E2 in SLE model mice increased,and the expression of mRNA of aromatase of renal tissue increased with E2 increment.Conclusion:E2 promotes development of SLE through regulating expression of aromatase mRNA.

Objective To assess the levels of nucleosomes released from peripheral blood mononu-clear cells(PBMC)of patients with systemic lupus erythematosus(SLE),and their relationship with auto-antibodies as well as disease activity.Methods Levels of both nucleosomes released from PBMC and vari-ous auto-antibodies were detected by ELISA in sera from SLE patients.The disease severity was evaluated using SLEDAI(systemic lupus erythematosus disease activity index)system.Results Levels of nucleosomes released from PBMC were significantly higher in patients with active SLE than those of patients with inactive disease and normal controls(39.39?25.70,13.44?8.82,and11.73?7.87IU/mL,respectively).There was a significant positive correlation between nucleosome levels and SLEDAI scores,serum ds-DNA auto-an-tibody levels,and low C3levels.Conclusion Nucleosomes released from apoptotic PBMC of patients with SLE is closely correlated to disease activity,which implies that nucleosomes may play an important role in the pathogenesis of SLE.

Objective To observe the effect of heat shock protein 70 (HSP70) expression induced by Herba Hedyotis Diffusae (HHD) on the apoptosis of H22 hepatoma cells.Methlds Mice were immunized with H22 hepatoma cells from in-vivo ascites of the mice pretreated by HHD and Radix Codonopsis (RC).Mice were divided into five groups after being blocked with HSP70 monoclonal antibody:non-HHD blocking group,HHD blocking group,non-RC blocking group,RC blocking group and the blank control group,10 mice in each groups.Then the mice were attacked with cultured H22 hepatoma cells to induce transplanted tumor.The apoptosis in the transplanted tumor was detected by a terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) method.Results Large amount of brown particles can be observed in the cell nucleus of transplanted tumor mice from HHD groups.Compared with RC groups,number of apoptotic cells and the staining intensity were increased in HHD groups.The apoptosis in HHD groups and RC groups differed from that in the blank control group,and was obvious in HHD groups.The apoptosis exerted a increasing tend in non-HHD blocking group,but the difference was insignificant between non-HHD blocking group and HHD blocking group,and between non-RC blocking group and RC blocking group.Conclusion HHD can promote the apoptosis of H22 hepatoma cells in transplated tumor through inducing the expression of HSP70 to some extent,and the related mechanism of inducing apoptosis needs further research.
