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.

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.

Objective To analyze the serum levels of medium-and long-chain free fatty acids (FFAs)in patients with hyperlipidemic non-alcoholic fatty liver disease (NAFLD) in order to shed some light on prevention and treatment of NAFLD.Methods The clinical data of 125 patients with high triglyceride (TG)levels who were treated in Hebei General Hospital from January 2011 to May 2011 were analyzed in this study.They were further divided into HF group (n =64) and H group (n =61) based on the presence of NAFLD or not.In addition,63 healthy individuals were recruited from the Central Hospital of Handan during the same period as the control group (N group).Serum medium-and long-chain FFAs were detected by gas chromatography.The body mass index (BMI),abdominal circumference,blood pressure,fasting blood glucose (FBG),and serum lipids including TG,total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),and low-density lipoprotein cholesterol (LDL-C) were measured.Results Compared with the N group,the H group had significantly higher BMI [(25.24 ± 1.41) kg/m2 vs.(24.32 ± 1.12) kg/m2,P =0.004],abdominal circumference [(84.72 ± 1.34) cm vs.(77.33 ±0.89) cm,P =0.010],and diastolic blood pressure [(77.35±1.21) mmHgvs.(75.21 ±1.61) mmHg,P=0.014]; also,the serum TG [(2.86±0.55) mmol/Lvs.(0.93±0.27) mmol/L,P=0.000] andTC levels [(4.56±0.66) mmol/Lvs.(4.36±0.47) mmol/L,P=0.000],serum myristic acid (C14∶0) [(0.49±0.04)％ vs.(0.36±0.01)％,P=0.011],palmitic acid (C16 ∶ 0) [(18.36 ± 0.47) ％ vs.(15.97 ± 0.30) ％,P =0.000],palmitoleic acid (C16∶ 1) [(1.00±0.12)％ vs.(0.58±0.02)％,P=0.001],and oleic acid (C18 ∶ 1) [(18.20±0.70) ％ vs.(12.23 ± 0.37) ％,P =0.000] all significantly increased,while stearic acid (C18 ∶ 0) [(7.52 ±0.22)％ vs.(8.15 ±0.28)％,P=0.012],eicosadienoic acid (C20 ∶ 2) [(0.61 ±0.07)％ vs.(1.03 ±0.17) ％,P =0.000],eicosatrienoic acid (C20 ∶ 3) [(1.77 ± 0.15) ％ vs.(2.49 ± 0.18) ％,P =0.002],and docosahexenoic acid (C22 ∶ 6) [(1.44 ± 0.08) ％ vs.(1.67 ± 0.09) ％,P =0.014] significantly decreased.Compared with the H group,the HF group had significantly higher weight [(85.76 ± 3.10) kg vs.(71.45 ±2.88) kg,P =0.003],abdominal circumference [(96.30 ±2.05) cm vs.(84.72 ± 1.34) cm,P=0.000],systolic blood pressure [(117.12 ±1.15) mmHg vs.(113.23 ±1.25) mmHg,P=0.009],and diastolic blood pressure [(79.54 ± 1.42) mmHg vs.(77.35 ± 1.21) mmHg,P =0.016],whereas the sreum FGB,TG,TC,HDL-C,and LDL-C showed no significant differentces; serum palmitic acid (C16 ∶ 0)[(19.54 ± 0.30) ％ vs.(18.36 ± 0.47) ％,P =0.000] also significantly increased.The serum level of eicosadienoic acid (C20 ∶ 2) in HF group was between that in N group and H group [(0.78 ± 0.09) ％ vs.(1.03 ±0.17)％,(0.78±0.09)％ vs.(0.61 ±0.07)％,both P=0.000].Conclusions The increased serum level of palmitic acid may be a risk factor for NAFLD.Reducing saturated fatty acids and increasing unsaturated acids in diets may be helpful for preventing NAFLD.

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.
