Objective To explore the effects of exercise with psychological rehabilitation on motor function of upper limbs for stroke patients with hemiplegia. Methods 34 stroke patients with hemiplegia were divided into treatment group (n=17) and control group (n=17). Both groups were treated with basic medication and exercise while the treatment group received psychological rehabilitation additionally. The motor function of upper limbs was evaluated with Fugl-Meyer assessment (FMA), and activities of daily living was assessed with Barthel index (BI) before and after treatment. Results After treatment, the scores of FMA and BI improved significantly in both groups (P<0.001), and was better in the treatment group than in the control group (P<0.001). Conclusion Exercise with psychological rehabilitation can effectively improve the motor function of upper limbs and activities of daily living for stroke patients with hemiplegia.

Objective To explore the evaluation value of modified USA National Institutes of Health Stroke Scale (mNIHSS) score combined with bedside transcranial Doppler ultrasonography (TCD) on the early prognosis of ischemic stroke (AIS).Methods One hundred and thirty-six anterior circulation AIS patients were collected,mNIHSS score was evaluated on admission,and emergency bedside TCD examination was performed to evaluate vascular anomalies.After active treatment after discharge,the modified Rankin scale (mRS) score was recorded to evaluate 90 d prognosis.The value of mNIHSS score combined with TCD examination analysis on the prognosis was analyzed.Results If the mNIHSS score ＞ 8 scores was judged to be poor prognosis,the sensitivity was 0.684,the specificity was 0.806,the positive predictive value was 0.578,the negative predictive value was 0.868.If related macro vascular abnormalities in bedside TCD examination were evaluated for clinical prognosis,the sensitivity was 0.736,the specificity was 0.643,the positive predictive value was 0.444,the negative predictive value was 0.863.If both,the specificity was 0.918,the positive predictive value was 0.714,the positive likelihood ratio was 6.41 ;and the two were not available,the negative predictive value was 0.928,negative likelihood ratio was 0.20.Conclusion mNIHSS score combined with TCD examination in evaluating the prognosis of AIS patients can improve the positive or negative predictive value.

Objective To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome. Methods PCR-RFLP was used to detect lipoprotein lipase Hind Ⅲ and S447X genotypes in 401 subjects(including 201 controls, 200 metabolic syndrome patients). Results ( 1 ) The levels of waist circumference ( WC ) , hip circumference ( HC ) , waist-to-hip ratio ( WHR ) , body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure ( DBP) , total cholesterol ( TC) , triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting plasma glucose (FPG) were significantly different between metabolic syndrome group and control group (all P< 0.05). (2)The frequencies of H+H+ genotype,H+allele,SS genotype, and S allele for metabolic syndrome were all significantly higher than those for controls( H+H+ genotype:66. 5% vs 54.2% ,P=0.012; H+ allele:78.0% vs 71.4%, P=0.031;SS genotype:89.5% vs 77. 1% , P = 0.001; Sallel:94.5% vs 87. 56% , P = 0.001). (3) The levels of WC, HC, WHR, BMI, SBP, DBP, TG, LDL-C, and FPG in H + H-/H-H- genotype were significantly lower than those in H+H+ genotype, HDL-C was significantly higher than that in H+H+ genotype ( all P<0. 05). The levels of WC, HC, WHR, BMI, SBP, DBP, TC, TG, and FPG in SX/XX genotype were significantly lower than those in SS genotype, HDL-C was significantly higher than that in SS genotype ( all P< 0.05). (4)Multi-way logistic regression analysis suggested that risk factors for metabolic syndrome were smoking, drinking, and SS genotype (OR value was 4.289,2.268, and 2. 597, respectively ). (5) Result of interaction analysis among different factors indicated that the risk for metabolic syndrome in smoker with SS genotype was 3. 996 times of non-smokers with SX/XX genotype. Conclusions The lipoprotein lipase gene S447X polymorphism is associated with metabolic syndrome risk in Kazakh, and SS genotype and S allele may serve as genetic risk factors of metabolic syndrome, H + H-/H-H- and SX/XX genotypes yield beneficial effect for lipid and blood pressure. SS genotype and smoking may exist additive effect.

Questionnaire-based survey, physical examination, and blood testing were conducted according to cluster random samplings in Kazakh residents in Xinjiang.2 760 samples were collected to analyze the association of different strata of waist circumference and clustering of metabolic syndrome (MS) components.Accoding to International Diabetes Federation standard, the prevalence of ≥1and ≥2 components of MS showed increasing trend with the increase of waist circunference, and odds ratio of clustering of MS components also increased significantly.The distance of receiver operating characteristic curve was the shortest and the prevalence of MS was 22.1% ;22.4% in men, and 21.9% in women;when the waist circumference was ≥91 cm for men, and ≥88 cm for women.

Objective To explore the regulation and effect factors of arsenic expose and arsenic methylation level, then to provide a reference for study the function of arsenic metabolism in a arsenic poisoning process. Methods A meta-analysis was performed by two researchers. Twenty-five papers satisfying our priori eligibility criteria were included by searching Cochrane library, Pubmed, Springer, Embase and China National Knowledge Infrastructure. Based on the results of heterogeneity, a random or fixed effects model was chosen for the meta-analysis. Results The results showed that the following arsenic metabolites increased (all P<0.01) following arsenic exposure: inorganic arsenic [iAs; standardized mean difference (SMD): 1.07; 95% confidence interval (CI):0.61 - 1.53)], monomethyl arsenic (MMA; SMD: 1.10; 95% CI: 0.81 - 1.40), dimethyl arsenic (DMA; SMD: 2.50;95%CI:1.50-3.69), and total arsenic (TAs, SMD:3.10;95%CI:2.13-4.07). Additionally, the percentages of iAs (iAs%; SMD: 1.00; 95% CI: 0.60 - 1.40) and MMA (MMA%; SMD: 0.49; 95% CI: 0.21 - 0.77) also increased, while the percentage of DMA (DMA%; SMD: - 0.55; 95% CI: - 0.80 - - 0.31) decreased (P<0.01). The primary methylation index (PMI; SMD: - 0.57; 95% CI: - 0.94 - - 0.20), and secondary methylation index (SMI;SMD: - 0.27; 95% CI: - 0.46 - - 0.09) decreased (all P< 0.01). Compared to female, male had higher MMA%(SMD:0.44;95%CI:0.35-0.52), lower DMA%(SMD:-0.33;95%CI:-0.38--0.28) and SMI (SMD:-0.36;95%CI:-0.53--0.19). The smoker had higher MMA%(SMD: 0.22; 95%CI: 0.07 - 0.37) and lower DMA%(SMD:-0.16;95%CI: - 0.26 - - 0.05). The drinker had higher MMA% (SMD: 0.17; 95% CI: 0.07 - 0.27) and lower DMA%(SMD:-0.24;95%CI:-0.39--0.10). The older people had higher MMA%(SMD:-0.23;95%CI:-0.40--0.06). In addition, the body mass index may influence the percentages of MMA (SMD: - 0.18; 95% CI: - 0.31 - - 0.04, P < 0.01). Conclusion Arsenic exposure, smoking, drinking, and older age can reduce the capacity of arsenic methylation. Arsenic methylation is more efficient in women than in men.

Objective To investigate the effect of acetyl-L-carnitine (ALC) preconditioning on the PC12 cell apoptosis induced by oxygen-glucose deprivation.Methods PC12 cells were seeded in 96-well plates and randomly divided into 5 groups ( n =6 each):control group (group C),cell injury group (group Ⅰ) and preconditioning with different concentrations of ALC groups (groups A1-3 ).In group C,the cells were incubated with DMEM liquid culture medium containing glucose 0.5 g/L for 3 h.In groups Ⅰ and A1-3 the cells were incubated with DMEM liquid culture medium containing sodium hydrosulfite (Na2S2O4) 3 mmol/L and glucose 0.5 g/L for 3 h,and in addition the cells were pre-incubated with ALC 0.2,0.4 and 0.6 mmol/L for 24 h in groups A1-3 respectively.Cell viability was evaluated by MTF assay,while the apoptosis in cells was detected using TUNEL.The activities of ATPase and SOD and MDA content were also detected.Results Oxygen-glucose deprivation significantly increased the number of apoptotic cells and the content of MDA,and decreased the cell viability and activities of SOD and ATPase in group Ⅰ compared with group C ( P ＜ 0.05).Preconditioning with ALC significantly increased the cell viability and the activities of SOD and ATPaes,and decreased the number of apoptotic cells and the content of MDA in groups A1-3 compared with group Ⅰ ( P ＜ 0.05).Conclusion ALC preconditioning can attenuate PC12 cell injury induced by oxygen-glucose deprivation through inhibition of apoptosis in cells.
