Objective To investigate the quality of life (QOL) of maintenance hemodialysis (MHD) patients and its influencing factors.Methods A total of 257 MHD patients in our hospital were recruited in this study.Clinical data of the patients were collected,and the QOL was assessed by MOS 36 item short form health survey(SF-36).Nutritional status of patients was evaluated by modified quantitative subjective global assessment (MQSGA).Univariate analysis of variance,pearson correlation analysis and multiple linear stepwise regression analysis were performed to determine the effect of related factors on QOL scores.Results The scores of all scales of SF-36 evaluation in MHD patients were relatively lower than that of general population as reported before.Their physiological component summary (PCS) score decreased gradually as age grew,nevertheless,the mental component summary (MCS) score was highest in the group aged 41-60.The score was lower in patients with moderate to severe malnutrition or diabetic nephropathy when compared with other patients.Univariate analysis of variance also revealed that high SF-36 scores associated with higher education or income.Multivariate analysis indicated that PCS score and total SF-36 score of MHD patients were positively correlated with body mass index (BMI) and cholesterol,but negatively correlated with diabetic nephropathy,pulmonary artery systolic pressure and MQSGA score (all P ＜ 0.05).There was positive correlation between MCS score and income,yet negative correlation between MCS score and MQSGA score (all P ＜ 0.05).Conclusion MHD patients had relatively poor QOL.Primary diseases and nutritional status were probably the main influencing factors.Age,educated level,family income and pulmonary artery systolic pressure might also have effects on their QOL.

Objective To investigate the changes of cardiac structure and function in type 2 diabetes mellitus (T2DM), analyze the related risk factors of heart failure, and improve the awareness of the effect of diabetes on the heart. Methods Randomly selected 170 cases of T2DM patients As the object of study, 170 cases of non diabetic patients as con-trol group, according to whether complicated with heart failure were divided into heart failure patients and non heart failure patients.Comparison of each group left ventricular posterior wall thickness, left ventricular end diastolic diameter, left ven-tricular end systolic diameter, left ventricular ejection fraction, E/A ratio Differences, analysis of the related risk factors of heart failure by logistic regressive.Results T2DM group left ventricular posterior wall thickness, left ventricular end diastolic diameter and left ventricular end systolic diameter increased , Left ventricular ejection fraction decreased, E/A ratio de-creased, were statistically significant difference compared with the control group (p <0.05).These differences are mainly come from non heart failure patients.Logistic regression showed that factors in patients with diabetes duration, HbA1c, com-pliance and complications of hypertension, coronary heart disease, is a risk factor for heart failure complicated with T2DM (all p<0.01).These may be the risk factor for diabetic patients with heart failure.Conclusion Diabetes can cause cardiac remodeling, systolic and diastolic dysfunction maybe some T2DM patients.They did not show symptoms of heart failure in the clinical, but their Cardiac structure and function are abnormal.We should pay attention to the cardiac function examination and early evaluation, prevention of risk factors, to avoid the occurrence of heart failure.

Objective To understand the incidence and clinical characteristics of scabies-associated glomerulonephritis and to investigate its pathogenesis.Methods The patients with scabies from Qijiang District People's Hospital.were collected from the outpatient department and divided into the simple scabies group (A) and glomerulonephritis group (B) according to whether complicating glomerulonephritis.The general clinical indicators and serum C-reactive protein(CRP),complement components C3 and C4,immunoglobulin,TNF-α,IL-6,IL-1β and IL-18 in the early stage of the disease were determined and compared between the two groups.The differences of above indicators were collected and compared between before and after clinical cure in the patients with scabies-associated glomerulonephritis.Results Among 376 cases of scabies,16 cases developed glomerulonephritis.The clinical manifestations included glomerular hematuria and/or mild-moderate proteinuria.The kidney injury manifestations in 12 cases were completely disappeared at 2-6 months after scabies cure.The levels of serum CRP,IgG,TNF-α,IL-6,and IL-18 in the group B were significantly increased and the serum C3 level was significantly decreased compared with the group A,the differences were statistically significant(P＜0.05).The levels of serum IgG,hs-CRP,TNF-α,IL-6 and IL-18 after cure in 12 cases of clinically cured scabies-associated glomerulonephritis were significantly decreased and the serum C3 level was significantly increased,and the difference was statistically significant compared with the early onset stage(P＜0.05).Conclusion The majority of prognosis in scabies-associated glomerulonephritis is good.Its occurrence is closely correlated with immune and inflammatory reactions induced by sarcoptes mites irffection.

BACKGROUND: Double gene transfection using bone morphogenetic protein 2 (BMP2) and vascular endothelial growth factor 165 (VEGF165) for bone marrow stromal stem cells (BMSCs) to induce osteogenesis provides experimental basis for the study on tissue engineering bone. OBJECTIVE: To investigate the ability of BMP2 and VEGF165 double gene modified rat BMSCs to induce osteogenesis. METHODS: BMSCs were isolated from the femur and tibia of four 4-week-old Sprague-Dawley rats by whole bone marrow adherent culture. Passage 3 BMSCs were randomized into five groups: non-transfection group, empty plasmid group, BMP2 transfection group, VEGF165 transfection group, BMP2 and BMP2/VEGF165 transfection group (co-transfection group). Then, western blot assay was used to detect expression of BMP2 and VEGF165 at 48 hours after transfection, and the activity of alkaline phosphatase was detected in each group at 7 days after transfection. RESULTS AND CONCLUSION: Highly expressed BMP2 in BMP2 and co-transfection groups and highly expressed VEGF165 in VEGF165 and co-transfection groups were found after transfection. The expression of BMP2 or VEGF165 in the co-transfection group was significantly higher than that in the BMP2 or VEGF165 transfection group after transfection, respectively (P < 0.05). Western blot results showed that the activity of alkaline phosphatase was ranked as: co-transfection group > BMP2 transfection group > VEGF165 transfection group > empty plasmid group and non-transfection group. There was a significant difference in the activity of alkaline phosphatase between co-transfection group and any of single gene transfection groups (P < 0.05). To conclude, BMP2/VEGF165 co-transfection promotes the ectopic osteogenesis of BMSCs.

AIM:To investigate the influence and mechanisms of human pancreatic cancer tumor microenvironments on T-cell immunoglobulin mucin-3 (TIM-3) expression and function of dendritic cells (DCs).METHODS:Tumor-infiltrating dendritic cells (TIDC) and para-carcinoma tissue DCs were isolated by Ficoll-Hypaque density centrifugation from trypsinized pancreatic carcinoma tissues, and the peripheral blood mononuclear cells were isolated from pancre-atic cancer patients or healthy people.The expression of TIM-3 on DCs was detected by flow cytometry.DCs isolated from healthy people peripheral blood mononuclear cells were induced by rhGM-CSF and IL-4.The expression of TIM-3 in the DCs treated with the culture supernatants of Capan-2, SW1990 and Panc-1 pancreatic cancer cells or human skin fibroblast (Hs27) cells for 48 h, and in the DCs treated with supernatants of Capan-2 cells, anti-VEGF-R2, anti-IL-10 and EP2 re-ceptor blocking peptide were evaluated by flow cytometry.The releases of IFN-βand IL-12 in the culture supernatants of DCs pretreated with monoclonal antibody ( mAb) to TIM-3 or DNase+RNase, followed by stimulation with apoptotic Ca-pan-2 cells, were detected by ELISA.RESULTS:DCs in tumor microenvironments had higher expression of TIM-3 than the DCs from para-carcinoma tissues and pancreatic cancer patient or healthy people peripheral blood ( P<0.01 ) .TIM-3 expression in the DCs treated with the culture supernatants of Capan-2, SW1990 and Panc-1 pancreatic cancer cells for 48 h was much higher than that in Hs27 cells (P<0.05).Treatment with a combination of anti-VEGF-R2, anti-IL-10 and EP2 receptor blocking peptide largely diminished the upregulation of TIM-3 on the DCs mediated by Capan-2 cell superna-tants (P<0.05).The concentrations of IFN-βand IL-12 in the DCs with high expression level of TIM-3 were lower than those in the DCs with low TIM-3 expression level.Treatment with mAb to TIM-3 resulted in much more IFN-βand IL-12 releases (P<0.01), but DNase+RNase made this effect disappear.CONCLUSION:TIM-3 serves as a negative regula-tor of DCs innate immune responses in the pancreatic cancer microenvironments.The secretion of soluble factors to tumor microenvironment by pancreatic cancer cells, including IL-10, VEGF and PGE2 , may contribute to the regulation of TIM-3 expression.

Objective To explore the effect of group psychological training on the mental health and self consistency of nurses from operating rooms.Methods 52 nurses of an operating room were randomized into the treatment group(n=25)and the control group(n=27): The latter received humane care and instructions for mental self care and the former received group psychological training for 8 weeks based on the same treatment as in the control group.Symptom checklist 90(SCL-90)and self consistency and congruence scale(SCCS)were used to assess and compare the difference of the two groups before and after training.Results The intra-and inter-group comparisons between pre-and post-intervention showed statistical differences in terms of the total score by SCL,interpersonal sensitivity,depression and hostility,total score by SCCS and the score on the subscale of inconsistency between themselves and their experience(all P<0.05 or P<0.01).Conclusion Group psychological training can effectively improve the level of mental health and self consistency of OR nurses and thus can improve the total psychological status of the OR nurses.

Objective To provide evidence for the prevention and control of nosocomial infection by knowing the infecting status of hospital.Methods The clinical data of 64 431 hospital patients from 2010 to 2012 were analyzed prospectively and retrospectively.Results A total of 2 636 patients of nosocomial infection were collected in 3 years,the infection rate was 4.09 ％ (2 636/64 431).Upper and lower respiratory tract was the main infection site.ICU,urology,neurology,endocrinology were the main infection outbreak departments.Gram negative bacilli was still the chief bacterium,accounted for 52.48％(689/1 313).Conclusion To strengthen the control of nosocomial infection and training of medical staff,strict insist on aseptic operation,reduce invasiveness operation,use antibacterial agent reasonable are the effective and preventative measures to decrease nosocomial infection.

Objective To explore the prevalence and the correlative factors of restless legs syndrome (RLS) in maintenance hemodialysis (MHD) patients.Methods The basic information and clinical laboratory results of 307 MHD patients were collected.The international RLS study group (IRLSSG) diagnostic criteria were applied to assess the presence and the severity of RLS.Binary logistic analysis was used for exploring correlative factors of RLS.Results The prevalence of RLS was 12.1％ in the MHD patients,with 73.0％ patients having mild-to-moderate symptoms and 83.8％ having chronic RLS.There was no significant difference between MHD patients with and without RLS in age,gender,dialysis age,daily urine,Kt/V,history of smoking,drinking,hemoglobin,serum creatinine,urea nitrogen,uric acid,calcium,phosphorus,magnesium,potassium,intact parathyroid hormone (iPTH),prealbumin,albumin and alkaline phosphatase.But the frequency of daily exercise in RLS group is significantly lower than that in non-RLS group (Z=-4.114,P ＜ 0.001).Logistic regression analysis showed that daily exercise was a correlative factor of RLS (B=-2.203,OR=0.111,95％CI 0.033-0.371,P ＜ 0.001).Conclusions RLS is a common complication in MHD patients,with chronic state and mild-to-moderate symptoms.RLS is correlated with daily exercise,which may be a scientific approach to treat or prevent this disease.

Objective To investigate the effect of rosiglitazone and insulin on islet ? cell function in latent autoimmune diabetes in adults (LADA). Methods Glutamic acid decarboxylase (GAD) antibody was screened in patients initially diagnosed type 2 diabetes. LADA patients, defined as positive GAD antibody and with a fasting C peptide of 300 pmol/L or more, were selected and randomly assigned to receive subcutaneous insulin alone ( n =6) or rosiglitazone combined with insulin ( n =6) to compare the changes of islet ? cell function. At entry and 1 year after treatment, blood was drawn to determine plasma glucose, HbA 1c and C peptide at fasting and 2 hours after taking 75 g glucose without medication. GAD antibody and C peptide were measured with radioligand immunoassay and radioimmune assay respectively. Results After 1 year treatment, LADA patients in rosiglitazone and insulin group had a higher postprandial C peptide than those in subcutaneous insulin group(782.1 pmol/L vs 1 695.0 pmol/L, P
