Objective To observe the relationship of the red blood cell distribution width and white blood cell count with coronary heart disease and coronary artery lesions.Methods Totally 590 patients undergoing coronary angiography were selected and divided into two groups based on the results of coronary angiography:coronary heart disease group (n=383) and control group (n=207).Based on the number of coronary lesions,patients in coronary heart disease were divided into different subgroup.The Gensini scores of coronary lesions were assessed.The differences in red blood cell distribution and white blood cell count were compared among different groups,and the correlations of coronary lesions with red blood cell distribution and white blood cell count were analyzed.Results The red blood cell distribution and white blood cell count were higher in coronary heart disease group than in control group [(13.06±0.57)％ vs.(12.63±0.49)％,(6.33±1.56) 109/L vs.(5.86± 1.29) 109/L,t=9.771 and 3.728,both P=0.000].The red blood cell distribution and white blood cell count were increased along with the increasing number of coronary lesions (F=51.454 and 7.544,both P=0.000),and positively correlated with the Gensini score (r=0.414 and 0.111,P =0.000 and 0.030).The red blood cell distribution was positively correlated with white blood cell count (r=0.108,P=0.009).The receiver operating characteristic(ROC) curve for red blood cell distribution predicting coronary heart disease showed that the threshold value of red blood cell distribution was 12.75％ and the area under the ROC curve was 0.723 (95％ Cl:0.680-0.765) with a sensitivity of 67.6％ and specificity of 65.2％ for the diagnosis of coronary heart disease.Conclusions Red blood cell distribution and white blood cell count are significantly increased in patients with coronary heart disease and are independently correlated with the severity of coronary lesions.Red blood cell distribution and white blood cell count are independent predictiors for coronary artery disease.

Objective To investigate the prevalence of psychological distress and analyze the relevant factors among patients with bladder tumor so as to provide evidence for future clinical practice. Methods Totally 128 patients were recruited from a urological surgery ward of a comprehensive hospital in Beijing in the study by using self-design questionnaire and the psychological distress thermometer (DT) recommended by the U.S. national comprehensive cancer network (NCCN). The acquired data were analyzed by SPSS17.0. Results The average score of the patients was 4.00(1.00~5.00). The identification rate of psychological stress was 55.47%( 71/128 ) , higher than the Chinese normal ( U = 8 . 28 , P < 0 . 05 ) . The relevant factors of psychological stress based on the rank from high to low scores included emotion problems ( 1 . 63 ± 0 . 67 ) , practical problems ( 1 . 42 ± 0 . 64 ) , communication problems (1.29 ± 0.65), physical problems (1.28 ± 0.33) and religion problems (1.00 ± 0.08). Conclusions The prevalence of psychological distress is higher among patients with bladder tumor and the influence factors mainly include emotional problems , practical problems and communication problems. Nurses should pay attention to the psychological distress of patients with bladder tumors and develop targeted interventions so as to relieve their distress.

Conclusions Oxidative stress and inflammation in OSAHS patients are increased,which are involved in the devel-opment of OSAHS associated hypertension.

Objective To analyze the characterization of cognitive function in Parkinson's disease with dementia and Alzheimer's disease. Methods Cognitive function was examined in Parkinson's disease with dementia (PDD) patients ( n = 30) , Alzheimer's disease (AD) patients ( n = 30) and healthy elderly control subjects ( n = 60) . Neuropsychological evaluation contained semantic fluency test, phonemic fluency test, action fluency test, objective and action naming tests. Results In PDD group , the score of semantic fluency test is 9. 33 ±2. 78, 6. 17 ± 1.67 of phonemic fluency test and 7.03 ±2. 34 of action fluency test,it is 6.90 ±2.47, 7.87±2.01,8.30±3. 17 of AD group. The score of objective and action naming tests is 36.33 ±3.39, 17.63 ±2. 17 in PDD group,while AD patients is 33.23 ±3.56 and 22.33 ±2.37. The verbal fluency tests and naming tests were impaired in PDD and AD patients compared with the healthy elderly control group (P ＜ 0. 01 ), phonemic fluency, action fluency and action naming were more impaired in PDD patients compared with the AD group , while semantic fluency and objective naming were more impaired in AD patients (P ＜ 0. 01 ). Conclusions Executive function deficit and naming impairment are found in PDD and AD patients, it shows that PDD is characterized by the addition of cortical dysfunction upon a predominant and progressive fronto-subcortical impairment. There is subcortical dysfunction in AD patients.

Objective To investigate the expression of BRAF-activated long non-coding RNA (BANCR) in colorectal cancer,and the influence of BANCR on the biological function of HCT116 cells.Methods Fifty-six samples of colorectal cancer specimen (including the cancer tissues and precancerous tissues) were obtained at the First Affiliated Hospital of Nanjing Medical University from March 2012 to June 2013.The expressions of BANCR in all the specimens were detected by qRT-PCR (28 cases in the BANCR-high expression group and 28 cases in the BANCR-low expression group).The relationship between the expressions of BANCR and the clinicopathological factors of colorectal cancer was analyzed.The HCT116 cells were divided into 4 groups after interfering BANCR with lentiviral-mediated shRNA-1 and shRNA-2:interference group 1 (HCT116 cells transfected with LV-shRNA-1),interference group 2 (HCT116 cells transfected with LV-shRNA-2),negative control group (HCT116 cells transfected with lentivirus vector with nonsense sequence) and blank control group (HCT116 cells cultured in RPMI 1640 medium).The proliferation,apoptosis and migration of HCT116 cells in the 4 groups were detected by CCK-8 assay,flow cytometry and Transwell assay,respectively.The comparison between the 2 groups was analyzed by u test,and multiple groups were compared by one-way analysis of variance,repeated measurement analysis of variance and LSD-t test.Multivariate analysis was done by Logistic regression model.The difference between categorical data was compared by chi-square test.Results The relative expression of BANCR in the cancer tissues was 1.6 ± 0.4,which was significantly higher than 0.9 ± 0.7 of the precancerous tissues (u =1 020.000,P ＜ 0.05).The result of univariate analysis showed that the high expression of BANCR was correlated with the lymph node metastasis and tumor stage (x2 =4.595,7.487,P ＜ 0.05).The result of multivariate analysis showed that lymph node metastasis and tumor stage (stage Ⅲ-Ⅳ) were the independent risk factors influencing the high expression of BANCR(OR =4.000,5.914,95％ CI:1.230-12.900,1.685-20.760,P ＜ 0.05).The relative expressions of BANCR of the interference group 1,interference group 2,negative control group and the blank control group were 0.25 ±0.04,0.20±0.06,0.96 ±0.04,0.98 ±0.03,with significant difference among the 4 groups (F =271.610,P ＜ 0.05).The cell proliferation rates at day 6 of the interference group 1,interference group 2 and the negative control group were 80.6％ ± 7.6％,81.2％ ± 5.1％ and 87.9％ ± 13.6％,with no significant difference among the 3 groups (F =0.559,P ＞ 0.05).The apoptotic rates of the interference group 1,interference group 2,negative control group and the blank control group were 4.7％ ± 1.7％,5.1％ ± 1.1％,3.1％ ± 0.6％ and 2.8％ ± 0.9％,with no significant difference among the 4 groups (F =2.881,P ＞ 0.05).The numbers of transmembrane cells of the interference group 1,interference group 2,negative control group and the blank control group were 135 ± 29,107 ± 18,240 ± 24 and 245 ± 22,with significant difference among the 4 groups (F =45.194,P ＜ 0.05).Conclusions BANCR was overexpressed in the HCT116 cells,and the BANCR overexpression was correlated with lymph node metastasis and tumor stage.BANCR can promote the migration of HCT116 cells.BANCR could be an important biomarker for the diagnosis and prognosis of colorectal cancer.

Objective: To analyze the clinical features in patients with hypertrophic cardiomyopathy (HCM) combining left ventricular apical aneurysm (LVAA) . Methods: A total of 1194 HCM patients treated in our hospital from 2007-01 to 2013-01 were studied. There were 23 (1.93%) patients combining with LVAA including 19 male and 4 female; coronary artery disease (CAD) was excluded and the patients received echocardiography and coronary angiography (CAG) examinations. Results: There were 21/23 LVAA patients having left mid-ventricular obstruction and 7 of them combining simultaneous left ventricular outflow obstruction.The average pressure gradient in those 21 patients was (56.8 ± 12.9) mmHg and the rest 2 patients suffered from apical hypertrophic cardiomyopathy.The mean maximum thickness of left ventricular wall was (21.8 ± 6.3) mm and the dimension of left ventricle was (39.4 ± 5.2) mm. Electrocardiography showed that 3 patients had paroxysmal ventricular tachycardia;CAG indicated that 6 patients combined with coronary artery muscular bridge at left anterior descending (LAD) artery. The patients were followed-up for (2.7 ± 1.3) years and adverse cardiovascular events occurred in 5 patients during that period. Conclusion: HCM combining LVAA was most frequently happened in patients with left mid-ventricular hypertrophic cardiomyopathy, some of them combining simultaneous left ventricular outflow obstruction and had the higher occurrence rate of adverse cardiovascular events. Early and accurate diagnosis is very important for guiding clinical treatment.

Objective:To measure the salary satisfaction level of medical staff in county-level public hospitals and provide reference for the design of policy reforms. Method:Eight county-level public hospitals were investigated. All analyses were performed using SPSS 19. 0 via statistical description and binary logistic regression. Results: The total salary satisfaction of the medical staff was 48 . 8%, and the average score was 54 . 05 ± 18 . 04 . The welfare satis-faction is the lowest (38. 8%), and the average score is 7. 98 ± 3. 51. Logistic regression analysis shows that the ac-ademic degree, department category, working hours per week, acceptance of bribes, and officially budgeted posts are the main factors affecting overall compensation satisfaction. Conclusion:The overall salary satisfaction level of medi-cal staff in county-level public hospitals is very low, and the welfare satisfaction is the lowest. Establishing the rea-sonable level of compensation, the rise of compensation, and the welfare mechanism are feasible choices to improve salary satisfaction.
