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 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.

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.

AIM: To investigate the CPU86017 and its enantiomers inhibit abnormal gene expression of calcineurin and NFκB in rat cardiomyopathy induced by L-thyroxin and compare the effect of CPU86017 (racemate) with its 4 enantiomers: (7S, 13R), (7S, 13S), (7R,13S), and (7R,13R)-CPU86017 in this model. METHODS: The animals were randomly divided into 7 groups. The rat hypertrophied model was produced by treatment with L-thyroxin 0.2 mg·kg-1·d-1, sc for 10 d and treated with CPU86017 or its enantiomers 4 mg·kg-1·d-1, sc from d 6 to d 10. The changes in left ventricular (LV) weight index, redox system, and the NO and iNOS activity in the myocardium were investigated. The expression of mRNA of calcineurin、NF-κB in the left ventricle was measured. RESULTS: There were significant cardiac hypertrophy and oxidative stress in rats treated by L-thyroxin. The expression of calcineurin, NFκB mRNA were upregulated (P<0.05, compared with that of control). After treatment with CPU86017 (racemate and enantiomers), LV remodeling and the redox system were improved. CPU86017 and (7S,13R)-CPU86017 showed a better improvement on LV remodeling and the redox than the other isomers and restored the normal expression of calcineurin, NF-κB (P<0.05, P<0.01), respectively. CONCLUSION: It suggested that an up-regulation of calcineurin and NFκB possibly related to the altered intracellular calcium handling system plays a role in the progression of L-thyroxin induced cardiomyopathy and CPU-86017 and its 7S,13R-CPU86017 enantiomer effectively inhibit the abnormal expression of calcineurin and NFκB genes, the NOS enzyme and oxidant stress in the cardiomyopathy.

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.

Methods HPLC was used to establish the fingerprint of aqueous extract of Chuanxiong Rhizoma, and multicomponent changes were detected at the same time. Closed-loop intestine method was used to study the multicomponent changes of oral administration of Chuanxiong Rhizoma after stomach-intestine-liver process. Results Totally 17 components were detected in the fingerprint of aqueous extract of Chuanxiong Rhizoma and they were basically stable in the digestive juice. For in vivo metabolism, 4 components were metabolized by intestinal flora;3 components were metabolized by liver;2 new components were the metabolites of intestinal flora;1 component was the metabolite of liver. Conclusion Multicomponent sequential metabolism and closed-loop intestine method were used to clarify that multicomponent metabolic profiling was feasible, and it could provide experimental basis for the metabolism of traditional Chinese medicine.
