Objective To explore the effect of Valpar occupational assessment training system on cognitive dysfunction in schizophrenia. Methods Sixty patients with schizophrenia were randomly assigned into Valpar therapy group ( experiment group, n=30) and traditional rehabilitation therapy group ( control group, n=30) according to the order number. The duration of the treatment was six weeks. The brief assess?ment of cognition in schizophrenia ( BACS) and Wisconsin card sorting test ( WCST) were conducted as pre?and post?treatment assessment. Results There were significant differences between scores of BASC in pre?and post?treatment assessment in experiment group. More specifically, the BASC scores in symbol coding (37.50±6.50, t=-4.60, P<0.01),token movement(60.80±8.72, t=-2.54, P=0.017),verbal memory (44.40±11.29, t=-2.19, P=0.037)),and word fluency(14.23±4.35, t=-3.39, P=0.002) were signifi?cantly different when comparing pre?and post?treatment assessment outcomes. In control group,the only sig?nificant difference was found in word fluency (14.23±4.35, t=-3.39, P=0.002).In addition,response errors (57.80±10.35, t=-3.06, P=0.005) and repeat errors (34.67±6.96, t=3.41, P=0.002) in WCST in exper?iment group were significantly different in pre?and post?treatment assessment while only repeat errors (34.30 ±7.01, t=4.36, P=0.000) was different in control group. It was further discovered that scores in in symbol cod?ing( t=2.010, P=0.048),token movement ( t=2.124, P=0.038),response errors ( t=2.413, P=0.020) and repeat errors( t=2.009, P=0.047) in WCST were different between two groups. Conclusion Valpar professional evaluation train?ing system can significantly improve the cognitive function of people with schizophrenia.

Objective To explore the association between polymorphisms in non-muscle myosin heavy chain 9 gene (MYH9) and hypertension susceptibility in chronic kidney disease (CKD)patients.Methods Five hundred and ninety-five persons,including 301 patients with CKD and 294 healthy controls,were enrolled in the study.Two single nucleotide polymorphisms (SNPs) (rs3752462,rs4821480) were genotyped by TaqMan assay or a restriction fragment length polymorphism assay for a further case-control study.The discrepancies of the patients'quantitive traits (including age,sex,systolic and diastolic blood pressure,frequency of different primary diseases and using different kinds of antihypertensive drugs) among different genotypes of the two MYH9 SNPs were analyzed.Meanwhile,the association between polymorphisms in MYH9 and hypertension susceptibility in CKD patients were analyzed in the rs3752462 site.Results The systolic blood pressure of CT genotype patients [(147.94± 27.40) mm Hg] was significantly higher than that of C C genotype patients [(136.43 ± 19.09)mm Hg] by single factor analysis of variance (P ＜ 0.05).The frequency of using all kinds of antihypertensive drugs for CC genotype patients (7.4％) was lower than that of TT (43.9％) and CT (48.7％) genotype patients (P ＜ 0.05).After correcting the age factor,the result of Logistic regression analysis showed that CC genotype was a protective factor of systolic blood pressure increasing.The probability of high blood pressure for CT genotype patients with CKD was 0.175 times than that of CC genotype (95％ CI 0.071,0.431).Conclusions The CKD patients who carry the rs3752462 site CC genotype of MYH9 gene are not prone to high blood pressure.Polymorphism of MYH9 gene rs3752462 site is associated with systolic blood pressure in CKD patients.It may indicate that allele C mutation for T can lead to the increase in systolic blood pressure.

The present study was to estimate pharmacokinetic parameters of metformin hydrochloride in 20 Chinese healthy volunteers with a limited sampling strategy (LSS), which will provide scientific data for bioequivalence and clinical application. A single dose of metformin was administrated to 20 healthy volunteers. The concentration of metformin in whole blood was determined by validated high performance liquid chromatography (HPLC) method. Multi-linear regression analysis was performed to establish a model to estimate AUC(0-24 h) and Cmax of metformin by LSS method. The LSS models were validated by the Jackknife method. The result indicated: the linearity relationship between AUC(0-24 h) or Cmax and single concentration point was poor. Several models for metformin AUC(0-24 h) or Cmax, estimation were better (r2 > 0.9, P < 0.05). Validation tests indicated that most informative sampling points (C2, C6 for AUC(0-24 h), C1.5, C2 for Cmax) provided accurate estimations of these parameters. So, a multi-linear regression model for estimation pharmacokinetic parameters of metformin by using LSS method is feasible.

Methods Using immunohistochemistry to detect the expression of CIP2A, bcl-2 and p63 in 30 cases of nodular goiter (NG), 30 cases of thyroid adenoma (TA) and 57 cases of PTC [including classical PTC (cPTC) 20 cases, papillary microcarcinoma (PMC) 20 cases, follicular thyroid papillary carcinoma (FPTC) 7 cases]. Results In NG group, TA group and PTC group, positive rates of CIP2A were 0, 0 and 94.74 % (54/57), respectively. The differences were statistically significant. In NG group, TA group and PTC group, positive rates of bcl-2 were 16.67 % (5/30), 13.33 % (4/30) and 85.96 % (49/57), respectively. The differences were statistically significant. In each group, positive rates of p63 were 6.67% (2/30), 3.33% (1/30) and 5.26% (3/57), respectively, no significant difference among them. In PTC, expression of CIP2A and bcl-2 were significantly higher than in NG and TA (χ2 = 105.56, P= 0.00; χ2 = 58.95, P= 0.00). Furthermore, the expression of CIP2A and bcl-2 had correlation in PTC (r=0.94, P=0.00). The expression of CIP2A, bcl-2 and p63 had no significantly difference among all the PTC subtype (χ2 values were 2.02, 2.64, 1.85; all P> 0.05). The expression of CIP2A, bcl-2 and p63 was not associated with patients'age, sex, site, lymph node metastasis (all P>0.05). Conclusions High expression of CIP2A and bcl-2 is associated with PTC, and the expression of CIP2A and bcl-2 has correlation in PTC. The expression of p63 has no correlation with PTC.

Background:Gastrointestinal dysmotility is frequently seen in patients with chronic obstructive pulmonary disease ( COPD). Simo Decoction is used for promoting gastrointestinal motility in clinical practice. Aims:To study the effect of Simo Decoction on gastrointestinal symptoms and motility in patients with COPD. Methods:Thirty-six patients with stable COPD in Shiyan Renmin Hospital from Sep. 2012 to Jun. 2013 were enrolled and received a 28-day course treatment of Simo Decoction oral solution,19 healthy volunteers were served as controls. All subjects were assessed with gastrointestinal symptom rating scale(GSRS). Electrogastrography was performed and levels of vasoactive intestinal peptide(VIP)and intestinal fatty acid-binding protein( I-FABP)in peripheral blood were measured. Patients with COPD were re-examined for the above-mentioned parameters after treated with Simo Decoction. Results:The baseline GSRS score and serum I-FABP level in COPD patients were significantly increased as compared with controls(P<0. 05),while the baseline serum VIP level,as well as the fasting and postprandial normal gastric slow wave percentage in COPD patients were significantly decreased(P <0. 05). After 28-day course of Simo Decoction treatment,all these parameters in COPD patients were improved as compared with those before treatment(P<0. 05),serum levels of VIP,I-FABP and normal gastric slow wave percentage were similar to those of controls. Conclusions:Simo Decoction can ameliorate the gastrointestinal symptoms and dysmotility in patients with COPD. The regulatory effect of Simo Decoction on gastrointestinal motility might be bidirectional.
