Objective To assessed the distribution of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in Xinjiang Uygur and Han nationality populations,and to investigate correlation and the incidence of all cases of macrovascular disease (coronary artery disease,carotid atherosclerosis and peripheral arterial disease)and analysis of risk factors.To further study the correlation between the incidence of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in type 2 diabetes melli-tus(T2DM)of Han and Uygur ethnic and the incidence of all cases vascular disease,then to analysis the risk factors. Methods 497 adults with T2DM who were treated in the Endocrinology department in hospital from May 2012 to April 2014 were involved in this study,including 298 Uygur patients and 199 Han patients.215 non -T2DMpatients who were treated in the Cardiology department in hospital were also involved in the study,including 93 Uighur patients and 122 Han patients.Then the total 712 patients were detectedby using PCR -SNP Stream technology to analyse rs2383206.rs10757278 loci SNP genotyping.The relevant results were compared with t test,two different genotype distribution and allele frequency were compared with χ2 test,multiple factors analysis were calculated by Logisitic regression.Results The distribution of genotype with two SNP loci had no significant difference between the patients in Uygur group and Han group (rs2383206χ2 =5.570,P =0.062;rs10757278 χ2 =2.721,P =0.257 ),and there's no significant difference between the patients with macrovascular disease and non -macrovascular disease in all patients(rs2383206χ2 =0.120,P =0.950;rs10757278 χ2 =1.027,P =0.598).Logisitic regression analysis showed that the incidence of macrovascular was significantly associated with increasing age(χ2 =28.820,P =0.000)and fatty liver(χ2 =5.210,P =0.020)in Uighur group with type 2 DM.In Han group with type 2 DM,the macrovascular was significantly associated with the increase of age (χ2 =19.980,P =0.000),elevated fasting blood glucose (FPG)(χ2 =4.070,P =0.044)and poor controlled with glycosylated hemoglobin (χ2 =4.280,P =0.040). Conclusion This study found that there's no correlation between two single nucleotide polymorphisms (SNPS)loci (rs2383206.rs10757278)on chromosome 9 p21 large with macrovascular in Uygur group and Han group.Increasing age,higher FPG and poor controlled with glycosylated hemoglobin combined with fatty liver were the risk factors for macrovascular.

Objective To study the recovery mechanism of dysphagic patients after stroke using functional magnetic resonanee imaging(fMRI). Methods Thirteen patients with dysphagia caused by unilateral cortical or subcortical lesions were recruited into a dysphagia group,and eight age-matched healthy volunteers were recruited as controls.Both grouDs performed experimental volitional swallowing tasks during fMRI studies.All patients of the dys-phagia group received rehabilitation treatment targeting dysphagia.Of the 13 dysphagia patients,7 reached almost complete recovery and were identified as recovered in follow-up fMRI studies.A 3.0 T MR scanner and echo planar imaging(EPI)T_2 WI sequence were employed to obtain the fMRI data.SPM2 software was used for post-processing of the fMRI data and displaying activated brain maps.Lateral index(LI)was calculated as LI:(C-1)/(C+I).Paired t tests were used to compare activated brain volume before and after complete recovery. Results Consistent activation of the bilateral primary sensorimotor cortex,anterior cingulated gyrus and the bilateral insular cortex were observed in the control group. Activation of the pons,medulla,left cerebellum,left prefrontal area,right occipital area and the left insular cortex were observed in the dysphagia group.Activation was observed in the bilateral primary sensorimotor cortex.bilateral prefrontal area,bilateral superior temporal gyrus,left insular cortex,bilateral frontal o-pereulum and anterior cingulated gyrus in the recovered patients.The total activated volume before recovery in the ip-silesional hemisDhere was significantly less compared with the contralesional hemisphere in the dysphagia group.In the recovered patients,both the activated brain volume of the ipsilesional hemisphere and value of LI were significant-ly larger than those at the initial examination.Conclusions Decreased activation in the sensorimotor cortex,the in-sular lobe and the cingulate gyms might be causes.of dysphagia.Compensation by the contralesional hemisphere in the early stages and then the restoration of the ipsilesional hemisphere after recovery may be mechanisms of dysphagia recovery in stroke patients.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.

OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.

METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.

RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).

CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.

Objective To investigate the in vitro effects of bladder cancer cell proliferation after silencing Notch1 gene. Methods The siRNA eukaryotic expression vector of Notch1 (psiRNA1)was constructed and transfected into bladder cancer cell lines T24 and BIU-87. Methabensthiazuron (MTT) and flow cytometry (FCM) assays were used to detect bladder cancer cells line growth, cell cycle and apoptosis after the transfection. RT-PCR and Western blotting were used to determine the expression changes of Notch1 in these cell lines. Results After transfection for 72 h, the rate of G0/G1 phase cells inceased from (23.89±1.32) % to (80.13±2.69)% in T24 cell line, and increased from (24.63±1.68)% to (69.44±2.41)% in BIU-87 cell line (both P<0.05). In addition, apop-totic cell index in T24 and BIU-87 cell lines increased from (1.28±0.14)% to (13.75±1.23)%, from (1.01±0.27)% to (8.72±1.01)%, respectively(both P<0.05). The growth of T24 and BIU-87 cell lines was obviously inhibited 24 h after the transfection, and the inhibitory effects lasted until 96 h after the transfection. Notch1 mRNA and protein significantly downregulated after transfection compared to the control(P<0.05). Conclusions Silencing Notch1 expression can inhibit the prolif-eration of bladder cancer cell lines. Notch1 gene might act as a tumor gene in bladder cancer.

Objective:To explore the mediating effect of coping efficacy on the relationship between psychological stress and adjustment.Methods:This study was a longitudinal study.Totally 267 college freshmen (137 males and 130 females,aged 19 to 21) were selected to fill in the China College Student Psychological Stress Scale (CCSPSS),China College Student Adjustment Scale (CCSAS) and Coping Efficacy Questionnaire (CEQ),each measurement interval two months,three times totally.Results:The CCSPSS scores were negatively correlated with scores of CCSAS and CEQ cognitive dimension (r =-0.29--0.08,Ps ＜ 0.05),and positively correlated with measurement period (represented by a continuous and dummy variable,r =0.08,P ＜ 0.05).The CCSAS scores were positively correlated with scores of CEQ cognitive dimension (r =0.25,P ＜ 0.01),and negatively correlated with measurement period (r =-0.13,P ＜ 0.01).The CEQ cognitive dimension scores was negatively correlated with measurement period (r =-0.14,P ＜ 0.01).The mediating effect analysis showed that coping efficacy played a partly mediating role between adjustment and psychological stress,measurement time,and the mediating effect were accounted for the total effect 45.7％,33.6％.Conclusion:It suggests that psychological stress and measurement time may not only directly affect the adjustment,but also indirectly affect adjustment through mediating effect of coping efficacy.

Verapamil was applied to PHT-CBZ resistant rats,followed by the observation on after discharge threshold (ADT),after discharge duration(ADD)and seizure activity.Results Compared with the control group, the ADT was higher in PHT-CBZ resistant rats peritoneally injected with verapamil((238.0?32.2)?A vs (177.0?23.3)?A,P

The effect of 1-deoxynojirimycin(DNJ)on the proliferation of rat mesangial cells was observed and its mechanism was explored.The results showed that DNJ significantly inhibited the proliferation of rat mesangial cells induced by high glucose in time-and dose-dependent manners.DNJ significantly decreased expressions of?-smooth muscle action(?-SMA),integrin?1 mRNA and protein and focal adhesion kinase (FAK)protein stimulated by high glucose in rat mesangial cells(P

Objective To investigate the attitudes of urban and rural community members toward total banning on smoking in public places and to explore the factors associated with these attitudes, in three counties/cities in China. Methods A cross-sectional study was conducted in three counties/cities in 2004, including Xin' an county of Henan province, Anyi county of Jiangxi province, and Mianzhu city of Sichuan province. A total of 5642 residents at age of 18-69 years old were interviewed face-to-face with a uniform questionnaire by locally-trained interviewers, through a random three-stage stratified sampling in each county. Factors were assumed to be associated with attitudes, using chi-square test in univariate analysis and non-conditional logistic regression model in multivariate analysis. Results The prevalence of current smoking among respondents was 44.3%. 80.7% (1379/1709) of the current smokers reported smoking often or sometimes in public places. Only 9.6% (479/4983) of the respondents reported that their indoor workplaces had totally banned on smoking. 43.5% of the respondents supported a total smoking ban strategy in pubic venues. The results of multivariate logistic regression model showed that eight factors were significantly associated with support for the total smoking ban in public places included region, residency, age, gender, education, smoking status, awareness about passive smoking hazards, and hearing of any message on tobacco control through media differences of rates regarding the factors as: residents in urban to rural areas (OR=1.29), elderly to youngsters (30-49 vs. 18-29, OR=1.46; 50-69 vs. 18-29, OR=1.71), female to male(OR=1.27), high-educated to less-educated ones, quitters to current smokers (OR=1.90), nonsmokers to current smokers (OR=2.01). Those who know messages on health hazards of passive smoking (OR=2.26), or heard of message on tobacco control through media (OR= 1.43). Conclusion Results from our study revealed that a thorough smoke-flee policy in public places should be developed and implemented in these three counties/cities.
