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 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.

A novel method for the detection of moroxydine ( ABOB) residue in tomatoes was developed based on the enhancement of the fluorescence intensity of CdTe quantum dots( QDs) in the presence of ABOB. The factors influencing the performance of the QDs fluorescent probes were investigated, and the optimum conditions were determined:the concentration of mercaptoacidic acid ( TGA) capped-CdTe quantum dot was 1×10-4 mol/L, and the reaction time was 20 min at pH=5. 6. Under the optimum conditions, the relative fluorescence intensity increases linearly proportional to the ABOB concentration in the range of 1. 0×10-12-5. 0×10-10 mol/L with a limit of detection of 5. 2×10-13 mol/L, R=0. 9981, the recovery was 97%-106%, without obvious interference on the determinations of moroxydine from the common coexisting ions, antibiotics, and vitamins. The proposed method has been successfully applied in the detection of trace moroxydine hydrochloride residue in tomatoes.

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 evaluate the applicability and security of transpancreatic precut sphincterotomy vs double guidewire technique for cannulation in difficult bile duct cannulation in endoscopic retrograde eholangiopancreatography (ERCP). Methods Retrospective analysis of 158 cases difficult bile duct cannulation in ERCP from January 2012 to January 2014, according to the intubation tube method, we divided all the cases into 3 groups, transpancreatic precut sphincterotomy group (group A); double guide wire technique group (group B); single guide wire technique group (group C). Then compare the intubation success rate and the incidence of complications among the 3 groups. Results 54 of 58 patients in group A intubation successful, the success rate is 93.1%, 50 of 56 patients in group B intubation successful, the success rate is 89.3%, 26 of 44 patients in group C intubation successful, the success rate is 59.1%, there was no significant difference between group A and B(P > 0.05), group A and group C, group B and C have significant difference (P < 0.05). In group A, 4 cases were complicated with acute pancreatitis, hemorrhage in 6 cases, infection in 2 cases, the complication rate is 20.7%; In group B, 5 cases were complicated with postoperative pancreatitis, 4 cases of infection, incidence of complications is 16.1%; 7 patients were complicated with pancreatitis in group C, hemorrhage in 2 cases, infection in 4 cases, complication rates is 29.5%, 3 groups were no perforation occurred.The complication rate of group B is lower than in group A, but no significant difference (P > 0.05), group A and group C, B and C complication rates had significant difference (P < 0.05). Conclusions When selective bile duct intubation is difficulty and guide wire thread into the pancreatic duct, continue to single guide wire have low intubation success rate and higher incidence of complications,transpancreatic precut sphincterotomy and double guide wire technique can effectively improve the success rate of intubation, and complication rates are relatively low, no significant difference between the two.

Objective To observe the effect of Herba Hedyotis Diffusae(HHD) on expression of heat shock protein 70(HSP70) and P16 anti-oncogene protein in mice with H22 cell transplanted tumor. Methods The mice were immunized with hepatoma-lines-H22 cells which were treated by Chinese herbs firstly. According to the pretreatment of the Chinese herbs and whether the H22 cells being blocked by HSP70 monoclonal antibody,the mice were divided into 5 groups:HHD non-blocking group,HHD-blocking group,Radix Codonopsis(RC)-blocking group,RC non-blocking group,and RPMI-1640 control group. Then the treated H22 Cells were translated into the mice. The expression of HSP70 and P16 anti-oncogene protein in mice with transplanted H22 liver carcinoma was detected by immunohistochemical marking method. Results The expressions of HSP70 was up-regulated in HDD non-blocking group and RC non-blocking group,in particular in RC non-blocking group,and the difference was significant as compared with HHD-blocking group,RC-blocking group and control blank group.The expression of P16 anti-oncogene protein was up-regulated in the treatment groups,and the difference was significant in comparison with the control group. The effect on P16 anti-oncogene protein expression was stronger in HDD groups than that in RC groups,but the difference was insignificant between the blocking group and the non-blocking group of each herb. Conclusion The anti-tumor effect of HDD may be achieved by inducing HSP70 expression in transplanted H22 neoplasia and by enhancing the immunogenicity. The up-regulation of P16 anti-oncogene expression by HHD and RC has no direct relationship with the induction of HSP70,and the related mechanism needs further research.
