OBJECTIVE:To study the effect of moxifloxacin on pharmacokinetics of phenytoin sodium in rabbits. METHODS: A total of 10 rabbits were injected with phenytoin sodium (10 mg?kg-1) via the vein in ear edge,with serum samples taken at 10,30,60,120,240,360,and 480 min,respectively for establishing phenytoin sodium alone group. 48 h after the last sampling,the rabbits were given oral moxifloxacin (10 mg?kg-1) for 5 consecutive days;on day 6,the rabbits were injected with phenytoin sodium (10 mg?kg-1) at 2 h after oral administration of moxifloxacin,then serum samples were taken at different time points for establishing combination group of phenytoin sodium and moxifloxacin. The serum concentrations of phenytoin sodium at different time points were determined by UV-spectrophotometry and the pharmacokinetic parameters were computed with 3p97 program. RESULTS: The plasma concentration of phenytoin sodium reduced in the combination group compared with alone group. The AUC in the two groups was (5 836.22?489.13) vs. (4 329.21?344.67) mg?min?L-1 (P0.05). CONCLUSION: The elimination of phenytoin sodium was significantly accelerated by combination with moxifloxacin.

Objective To investigate the elationship between the expression of Cathepsin D and Laminin receptors with the invasion and metastasis of gastric cancers.Methods Cathepsin D and Laminin receptors immunoreactivities were evaluated in 96 patients with gastric cancer using streptavaclin pemxidase method.Results Over expression of Cathepsin D in gastric cancer tissue was significantly related with the depth of invasion,lymphnode metastasis and grade of differentiation (P<0.01,P<0.01 and P<0.05, respectively).Moreover,the high expression of Lamninin receptors in gastric cancer had significant correlations with the invasion depth and grade of differentiation(P<0.05 and P<0.01);The positive expression of Laminin receptors were not significantly related with lymph node metastasis(P>0.05).By statistics analysis Cathepsin D had a significant positive correlation with Laminin receptors (P<0.05). Conclusion Cathepsin D and Laminin Receptors play all important role in the invasion and metastasis of gastric Cancers.

ObjectiveTo investigate the effects of liraglutide on the differentiation of human bone marrow mesenchymal stem cells (hBM-MSCs) into insulin-producing cells (IPCs).MethodsIn vitro,hBM-MSCs were induced into IPCs by three-stage induction procedure containing high glucose,nicotinamide,and liraglutide.The morphological change of cells was observed by inverted microscope during induction and the induced cells were confirmed by dithizone(DTZ) staining.The protein expressions of pancreatic and duodenal homeobox-1 (PDX-1),glucose transporter 2 (GLUT2),glucokinase(GK),and insulin in each stage of the induced cells were detected by Western blot.Insulin secretion was measured by ELISA.ResultsThe induced effect was pronounced after adding 10 nmol/L liraglutide for 7 days.Cells began to aggregate and get round gradually during induction,and the morphology of most cells appeared as grape-like aggregation and clustered islet-like cells by the end of induction.The number of DTZ positive cells and the protein expressions of PDX-1,GLUT2,GK,and insulin were increased gradually( P＜0.05 ).The basal and glucose-stimulated insulin secretion from induced cells was also increased gradually(P＜0.05).Conclusion BM-MSCs could be induced into IPCs by high glucose,nicotinamide,and liraglutide in vitro.

ObjectiveTo study the self-choice right of the patients who visit psychology department in TCM hospitals and provide a reference for further TCM psychological treatment application.Methods Self-choice and visiting condition inquiry enacted by ourselves was used in the survey.It is an unregistered and on-sight investigation.The inquiries were distributed by doctor.Patients were instructed by their doctors in the process.Results64.35％ of patients in psychology department of TCM hospitals select treatment methods by themselves.TCM is the first choice among 66.96％ of patients in psychology department of TCM hospitals.44.35％ of patients visiting psychology department refuse western medicine due to their side effects.6.09％ of patients in psychology department of TCM hospital know a little about psychological treatment; however,some of them believe in psychological treatment.ConclusionThe research finds out the main methods of self-choice right among patients visiting psychology department of TCM hospital.It proposes that self-choice right should be respected,at the same time,doctors are responsible to guide patients to understand the etiology of diseases.These efforts will contribute to harmony relationship between doctors and patients and facilitate their recovery and rehabilitation.

Objective Discbuss the hypertension prevalence rate in the Wuhan male taxi drivers and the dangerous factor to provide the basis for its professional publie health work. Methods The Wuhan male taxi drivers were carried on the healthy physical examination who in the Hubei province medicine medical examination center during 2005-2007 and were carried on the epidemiology statistical analysis. Results The Wuhan male taxi drivers hypertension prevalence rate is 28.28%. That is higher than the common crowd. Hypertension leaves outside the heredity factor and be closely correlated with the age of harnesses, the body weight index, and so on. Conclusions The Wuhan male taxi drivers'hypertension prevalence rate is unoptimistic. We should take the synthesis preventing and controlling measure to reduce this crowd hypertension prevalence rate.

Objective To investigate the effects of 2.45 GHz microwave on the apoptosis of HeLa cells and explore the underlying mechanism.Methods HeLa cells were divided into five groups randomly:control group,sham-irradiation group,and three irradiation groups exposed with 10,15 and 20 mW/cm2 2.45 GHz microwave for 10 min.Cell survival was tested by MTT assay,cell nucleus fashion was observed by a laser scanning confocal microscope,cell cycle distribution was measured by flow cytometry,and cell protein expressions were detected by Western blot.Results The cell survival in control group,shamirradiation group and low dose irradiation group had no difference but it became lower in the middle and high dose irradiated group(t =-16.47,-14.23,P ＜ 0.05).The abnormal rates of nuclear fashion in the low,middle and high dose irradiation groups were obviously higher compared with control group (t =9.37,11.25,8.47,P ＜ 0.05),while high dose irradiation group was higher than the low and middle dose group (t =15.32,10.25,P ＜0.05).The rate of HeLa cells in sub-G1 in the irradiation groups were higher than that in control group (t =15.24,22.31,10.69,P ＜ 0.05).The results of immunohistochemistry showed that the expression of Bax and Caspase-3 in irradiation groups was significantly increased,and the expression of Bcl-2 was decreased.Conclusions 2.45 GHz microwave can induce HeLa cells apoptosis with a positive correlation with microwave dose.

To investigate how to promote the psychotherapy work of TCM in community hospitals. After a period of time developing the group psychotherapy of TCM and the community health education, Psychotherapy of TCM in community were promoted. In the community hospitals the psychotherapy work of TCM was carried out smoothly, and has been widely recognized and praised.

Objective To investigate association of the DTNBP1 gene polymorphisms with paranoid schizophrenia in Chinese Han populations by a two-stage study.Methods In the discovery stage, 11 SNPs in DTNBP1 were tested in 532 patients with paranoid schizophrenia and 488 controls by Sanger sequencing.In the validation sample (1 111 cases and 1 435 controls), Taqman genotyping method was used to genotype SNP rs4715986.Results In the discovery stage, SNP rs4715986 showed disease association (χ2=11.02, P<0.01) with paranoid schizophrenia for analysis of 532 patients and 488 controls;such an association survived a correction with 10 000 permutations (corrected P<0.05).In the validation sample (1 111 cases and 1 435 controls), we confirmed the genotypic association (χ2=9.292, P=0.01) of rs4715986 with paranoid schizophrenia.Conclusions The present results suggest that the DTNBP1 gene may be mainly involved in the development of paranoid schizophrenia in the Chinese Han population.
