Objective To observe the changes in plasma leptin in type 2 diabetic patients after treatment with ?-glucosidase inhibitor (Acarbose) and investigate the relationships between them.Methods A 8-week randomized double-blind was performed to compare the effects of treatment with Acarbose (50mg, tid) in 43 type 2 diabetic patients. Results (1) When type 2 diabetics compared with non-diabetic controls, fasting plasma glucose(FPG), 2-hr of postprandial plasma glucose (2hBG), A1C, fasting insulin(FIns), triglyceride(TG) and cholesterol(TC)were elevated significantly,2-hr of postprandial insulin(PIns), HDL-C were decreased(P0.05).(3)In type 2 diabetes, there were positive relationships between leptin and BMI, leptin and fasting insulin , leptin and 2-hr of postprandial insulin.(4)After 8 weeks of treatment with acarbose, FPG, 2hBG, A1C, FIns, PIns,Ch and TG decreased significantly (P0.05).Conclusions: When age, gender, and BMI were matched with the controls, the level of leptin in type 2 diabetic patients still has no difference. Acarbose may lower the change in leptin and improve hyperinsulinemia.

Objective To investigate the biological characteristics and epidemiological significance of Yersinia pestis strains in Qilian County,Qinghai Province,in order to provide a scientific basis for plague prevention and control.Method Totally 67 strains were separated from kinds of host in Qilian County,Qinghai Province from 1958 to 2011,to do biochemical test,toxicity test,virulence factors evaluation,plasmid analysis and different region (DFR) genotyping.Results According to biochemical typing,48 of the 50 strains tested were Qing-Tibet Plateau ecotype,15 were Qilian Mountain ecotype,and the remaining 4 were different ecotypes from the plague foci in Qinghai plateau.The strains had 8 genomovars,and were given priority to genomovar8 (42 strains),secondly,genomovar44 (15 strains),genomovar5 (4 strains),genomovar7 (2 strains),genomovar19 (1 strain),genomovar30 (1 strain),genomovar32 (1 strain),and genomovar34 (1 strain).A proportion of 95.52％ (64/67) of the strains contained 3 kinds of plasmid-6 × 106,45 × 106,and 52 × 106;85.07％ (57/67) contained all the four virulence factors,and 96.00％ (48/50) were velogenic strains.Conclusion The strains separated in Qilian County,Qinghai Province have the characteristics of Qinghai-Tibet Plateau plague's pathogen and have strong toxicity,so we should enhance the plague monitoring and give more publicity to plague prevention to prevent animal plague spreading to human.

OBJECTIVETo detect mutations of the retinitis pigmentosa GTPase regulator (RPGR) gene in two Chinese X-linked retinitis pigmentosa families.

METHODSFragments of exons 1-19 of the RPGR gene were amplified with intronic primers, using genomic DNA as template. The polymerase chain reaction (PCR) products were analysed by single-strand conformation polymorphism (SSCP) and direct sequencing. Mutations were identified by comparing DNA sequences of the patients with those of the normal controls.

RESULTSTwo novel mutations, c1536delC and E332X, were identified in exons 12 and 9 of the RPGR gene in both families. Each mutation was the first mutation found in their respective exons. Both mutations were predicted to cause premature termination, which resulted in truncated proteins without normal functions of the RPGR products.

CONCLUSIONSBoth mutations are the genetic basis of the pathogenesis in the respective families. Our data might be helpful in analysing the function of the RPGR protein.

This study was aimed to compare the effect of insulin plus rosiglitazone with that of insulin plus metformin on the level of serum N-terminal pro-brain natriuretic peptide (NT-BNP) in patients with type 2 diabetes mellitus, and to find out whether serum NT-BNP can be used as an index for predicting heart failure induced by rosiglitazone in the cases of type 2 diabetes mellitus. Sixty type 2 diabetic patients were recruited and were randomly divided into two groups: group A (n = 30) received insulin plus rosiglitazone (4 mg/d) and group B (n = 30) received insulin plus metformin. The observations covered an 8-weeks' course of treatment. Serum NT-BNP was measured at the beginning and at the end of 8 weeks. The Before-After study revealed that the level of serum NT-BNP did not change apparently in the two groups (P >0.05). There was no remarkable difference in the level of serum NT-BNP between the two groups (P>0.05). There were 3 cases with edema in the group of insulin plus rosiglitazone, but none with heart failure; in these three cases, the mean serum NT-BNP level at the end of the treatment exhibited an increase of 108.99 fmol/ml when compared with that at the beginning. Neither insulin plus rosiglitazone nor insulin plus metformin had apparent effect on the level of serum NT-BNP in the patients with type 2 diabetes mellitus. The question of whether serum NT-BNP is a predictive index of heart failure awaits answers given by more observation on type 2 diabetes mellitus patients using rosiglitazone.

Objective:To investigate risk factors for the efficacy for appropriate medication use in elderly patients with type 2 diabetes mellitus(T2DM)and to establish a risk prediction model for the efficacy for appropriate medication use by using Logistic regression analysis and the receiver operating characteristic(ROC)curve.Methods:A total of 305 elderly patients with T2DM admitted to pharmacy department of our hospital from Jan.2018 to Aug.2018 were enrolled in this retrospective study.Of the 305 patients, 166(54.4%)were female, with a mean age of (74.9±7.2) years old, a disease course of (15.2±9.6) years and a hospital stay of (10.4±3.2) d, receiving (2.0±0.9) types of antidiabetic drugs.Patients were assessed by the Self-Efficacy for Appropriate Medication Use Scale(SEAMS), the Morisky Medication Adherence Scale-8(MMAS), the Adherence to Refills and Medications Scale(ARMS), the Charlson Comorbidity Index(CCI)and the Mini Mental State Exam(MMSE). Main biochemical indicators were recorded.The influencing factors for appropriate medication use efficacy were analyzed by Logistic regression analysis, and a risk prediction model was consequently established by the ROC curve.Results:According to SEAMS results, 233 patients(76.4%)had sufficient efficacy(≥26 points)and 72 patients(23.6%)had insufficient efficacy(<26 points). There were significant differences in parameters including age, disease course, hospital stay and fasting blood glucose(FBG)between the above two groups( P<0.05). Logistic regression analysis showed that age, FBG level and ARMS score had correlation with self-efficacy for appropriate medication use( P<0.05). ROC curves showed that the predictive efficiency of joint predictor Y [Logit(P)=-15.164+ 0.434X ARMS score-0.067X age-0.082X FBG reaching standard]was better than that of the other three single factors(AUC=0.910, 95% CI: 0.873-0.947, P<0.01)and could be used as an optimal predictor for the evaluation of self-efficacy for appropriate medication use. Conclusions:Compared with MMAS, ARMS is more suitable for medication adherence assessment in elderly T2DM patients.In clinical practice, pharmacists can provide individualized medication services through evaluating the efficacy of rational drug use and the risk prediction model, in order to elevate the ability of self-medication management and quality of life.
