Objective The different distribution and clinical significance of mean platelet volume (MPV) in the healthy normoglycemic and impaired fasting glucose (IFG) individuals were discussed.Methods The 499 individuals including 184 male and 315 female,who had undergone health checks in Tianjin Huanhu Hospital during May and July 2012 were studied retrospectively.Average age is forty-five ( thirty-five to eighty).Subjects were categorized into four groups according to fasting plasma glucose ( FPG) levels:G1 (3.89 mmol/L≤FPG<5 mmol/L, n=125),G2(5 mmol/L≤FPG <5.5 mmol/L, n=121), G3(5.5 mmol/L≤FPG<6.1 mmol/L, n=142), and G4(6.1 mmol/L≤FPG<7 mmol/L, n=111).G1, G2, and G3 are defined as normal FPG groups and G 4 is defined as IFG group.Eighty-nine cases in the same age patients with type II diabetes mellitus group ( G5 ) were observed at the same time.Results The MPV increased with the increasing FPG levels in the following order:G1(8.62 ±0.77) fl, G2 (8.85 ±0.80) fl, G3(8.90 ±0.69) fl,G4(9.14 ±0.78) fl and G5(12.03 ±1.42) fl.MPV[(12.03 ±1.42) fl] of type Ⅱdiabetes mellitus group(G5) was higher than that in the IFG group (G4)[(9.14 ±0.78) fl] and normal FPG groups[G1(8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01);MPV of the IFG group [ ( 9.14 ±0.78 ) fl ] was significantly higher than that in normal FPG groups [ G1 (8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01 for G4 vs.G1 and G2, P<0.05 for G4 vs.G3) ;MPV in the high-normal glucose group (G3) [(8.90 ±0.69) fl] was obviously higher than that in the low-normal glucose group (G1) [(8.62 ±0.77) fl] (F=12.773,P<0.05);MPV was positively associated with FPG in normal FPG groups ,IFG group and type Ⅱ diabetes mellitus group (G1-3:r=0.22, P<0.05;G4:r=0.26, P<0.01;G5:r=0.29, P<0.01).Conclusions Significant difference of MPV was observed in population of different FPG levels.Especially, MPV in IFG group was evidently higher than that in normal FPG group and was positively associated with FPG levels.

Objective To investigate the relationship between personal disposable income and female depression,and to examine the moderating roles of personality in this link.Methods The demographic questionnaire,self-rating depression scale (SDS) and eysenck's personality questionnaire short scale (EPQ-RSC) were used to survey 139 cases of married female patients with depression.Results Personal disposable income could be used to significantly and negatively predict female depression(β=-0.669,P＜0.01).The interaction between personal disposable income and introversion-extroversion,personal disposable income and neuroticism was significant (β=0.142,P＜0.05.β=-0.232,P＜0.01).In the groups of higher and lower scores on the introversion-extroversion dimension,personal disposable income could be used to significantly predict female depression(β=-0.397,P ＜0.05.β=-0.452,P＜0.05).In the group of higher scores on the neuroticism dimension,personal disposable income could be used to significantly predict female depression(β=-0.553,P＜0.01),but not in the group of lower scores(β=-0.349,P＞0.05).Conclusion Personal disposable income has significantly negative prediction effect on female depression,and introversion-extroversion and neuroticism have significant moderating effects on the relationship between personal disposable income and female depression.

Objective To study the mutations of Env sequence of SIVmac239 after infection of Chinese rhesus monkeys, and compare the differences and characteristics of Gp120 sequences of enterotropic and neurotropic SIV strains. Methods Six strains of simian immunodeficiency virus were analyzed in this study: four separated from peripheral blood mononuclear cells of SIVmac239-infected monkeys and two neurotropic SIVmac251 strains.Isolated and cultured monoclonal virus was obtained by limiting dilution assay.Gp120 sequences were amplified after the RNA extraction and phylogenetic analysis was processed thereafter.So did the Gp120 amino acid sequence and N-glycosylation sites analysis of the enterotropic and neurotropic strains.Results SIVmac239 had different mutations in four rhesus monkeys.The diversity in amino acid sequences of the enterotropic and neurotropic strains concentrated in the V1 and V4 regions of Gp120.The enterotropic strains had an addition of glycosylation site in V4 but the glycosylation site changes of neurotropic strains were located in the conservative regions of C1, C2 and C3.Conclusions The addition of one glycosylation site in V4 region of GP120 and loss of one glycosylation site in C1 region are associated with enhanced enterotropism and neurotropism.The differences between the enterotropic and neurotropic strains are not dipicted in Gp120 V3 region which is closely related with the tropism of strains.

In order to establish a rapid method for identifying six constituents in Guizhi Fuling capsule, Q-TOF with DART ion source was used to perform the direct analysis of compounds in Guizhi Fuling capsule. The DART sampler delivery rate was 0.2 mm s(-1). The temperature of helium gas of DART was 450 degrees C. The capillary voltage was kept at 1 000 V. The temperature of the drying gas of Agilent 6538 Q-TOF MS was set at 350 degrees C. The flow rate of the drying gas of MS was set at 3.5 L x min(-1). The MS scan range was m/z 50-1 000. Based on accurate mass measurements and the elemental compositions of the product ions and fragmentation patterns of reference conpounds, six components, amygdalin, paeonol, paeoniflorin, cinnamic acids, gallic acid, benzoic acid were identified rapidly. The method can rapidly identify six chemical constituents in three batch of Guizhi Fuling capsule. The DART-Q-TOF-MS method is simple, rapid and specific and it can be used for rapid identification and characterization of compounds in traditional Chinese medicines.

To systematically evaluate the efficacy and safety of tripterygium glycosides (TG) combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV. The computer retrievals were made in Cochrane Libarary, PubMed, Embase, SCI, Sinnomed, CNKI, Chinainfo and VIP, and hand retrievals were conducted for meeting and academic papers (updated to December 30, 2014), in order to collect randomized controlled trials and quasi-randomized control trials for TG combined with ACEI/ARB preparation in treating diabetic nephropathy stage IV and set the literature inclusion and elimination standards. Eligible literatures were included and evaluated according to standards in Cochrane Handbook. RevMan 5.3 and Stata 12.0 were used for a Meta-analysis. A total of 13 randomized controlled trials and quasi-randomized control trials involving 1119 patients with diabetic nephropathy were included. The Meta analysis result showed that compared with the control group, the combination group showed better effects in reducing the 24-hour urinary protein [MD = -0.84, 95% CI (-1.02, -0.66)], raising albumin [SMD = 0.98, 95% CI (0.81, 1.16)], the total efficiency [OR = 4.23, 95% CI (2.77, 6.46)] and the significant efficiency [OR = 5.35, 95% CI (2.70, 10.60)], with no statistical difference in Serum Creatinine between Both groups [MD = -0.82, 95% CI (-4.30, 2.66), P = 0.64]. However, the risk of adverse reactions increased by 7% [RD = 0.07, 95% CI (0.03, 0.12)]. The Egger's test showed no publication bias. Tripterygium Glycosides combined with ACEI/ARB in treating diabetic nephropathy stage IV is supper than the single administration of ACEI/ARB, with a good prospect in clinical application. Nevertheless, due to the small-size and low-quality samples in this study, more high-quality and large sample-size randomized controlled trials shall be conducted to verify the findings.
