Objective To investigate the change in natural kill cell,T-ly mphocyte subset counts and effect of recovery after homologous and autologous blood transfusion.Methods 50 patients undergoing lung cancer operation were randomly divided into two groups:group A received autologous blood transfusion with 400ml and group H received homologous blood transfusion with 400ml.Venous blood samples were taken before surgery,before blood transfusion and on the 1st and 5th postoperative day for determination of T-ly mphocyte subsets and natural kill cell counts by flow cytomet.The existent ratio of 1～3 years were followed up.Results The NK cell,CD+_3 and CD+_4 counts and CD+_4/CD+_8 ratio decreased significantly on the 1st postoperative day in both groups(P

Objective To summarize clinical data of 33 patients with off-pumb coronary artery bypass grafting(OPCABG) procedure and analyze the benefit and curative effects of OPCABG procedure. Methods From February 2002 to June 2005,33 patients with cardiac function in class Ⅱ-Ⅲ (NYHA) and left ventricular ejection fraction(LVEF) was 34%-68%,and all of them underwent coronary artery bypass grafting(CABG) surgery without cardiopulmonary bypass. Results After operation,There was no death, the cardiac function improved in various degree. Preoperative angina disappeared. Conclusion OPCABG procedure is a safe, available, effective method for coronary artery disease.

Objective To summarize the experience of surgical treatment of venous drug-induced infective endocarditis(IE). Methods The 17 cases of drug-induced IE were found to have valvular vegetations,16 patients had involvement of tricuspid valve, 1 mitral valve associated with ventrieular septal defect. Preoperative blood culture was positive in 8 patients. The operations included tricuspid valve repair (6 cases),tricuspid valve replacement(8 cases), mitral valve replacement and VSD closure(1 cases). Results All patients were alive and discharges. After follow-up of 6 months to 6 years, 1 case had severd tricuspid alve regurgitation, 1 had haemoptysis because of incorrect anticoagulation. Conclusions This study indicated surgical intervention is effective treatment of venous drug-induced infective endocarditis.

0bjective To synthesis evidence of self-efficacy-based interventions to improve self-management and health behaviour change in patients with diabetes. Methods PubMed, Cochrane, MEDLINE, CINAHL, EBSCO and Web of Science were searched from 1977 to August 2018. The primary outcomes were self-efficacy and self-care ability. Pooled effect sizes of standardised mean difference ( SMD ) were calculated if outcome measurements and the units were different, and if outcome measurements and the units were the same, such as measuring blood glucose by HbA1c, weighted mean difference ( WMD ) were used to calculate pooled effect sizes. Results Nine eligible randomised control trials (RCTs) including 1578 participants were identified. The results showed that interventions based on self-efficacy significantly improved patients′self-efficacy ( SMD=0.69, 95% CI :0.58 to 0.80, P＜0.05) and self-management ( SMD=0.93,95% CI : 0.74 to 1.12, P＜0.05), helped them control blood glucose ( WMD=-0.69, 95% CI :-0.85 to-0.52, P＜0.05), reduced hospitalisation and emergency times, and improved their quality of life ( SMD=0.52,95% CI : 0.32 to 0.72, P＜0.05). Conclusions Even though the results showed significant improvement in self-efficacy and self-management after interventions, the conclusion needs to be generalised with caution because of the quality of RCTs and high heterogeneity. Future trials could consider RCTs with high quality, appropriate sample size, specific component of diabetes management, and reliable and valid scales or objective measures as outcomes.

Toxocara vitulorum has been rarely reported in yaks at high altitudes and remote areas of Sichuan Province of Tibetan Plateau of China. The current study was designed to investigate the prevalence, associated risk factors, and phylogenetic characteristics of T. vitulorum in yak calves on the Qinghai Tibetan plateau. Fecal samples were collected from 891 yak calves and were examined for the presence of T. vitulorum eggs by the McMaster technique. A multivariable logistic regression model was employed to explore variables potentially associated with exposure to T. vitulorum infection. T. vitulorum specimens were collected from the feces of yaks in Hongyuan of Sichuan Province, China. DNA was extracted from ascaris. After PCR amplification, the sequencing of ND1 gene was carried out and phylogenetic analyses was performed by MEGA 6.0 software. The results showed that 64 (20.1%; 95% CI 15.8–24.9%), 75 (17.2; 13.8–21.1), 29 (40.9; 29.3–53.2), and 5 (7.6; 2.5–16.8) yak calves were detected out to excrete T. vitulorum eggs in yak calve feces in Qinghai, Tibet, Sichuan, and Gansu, respectively. The present study revealed that high infection and mortality by T. vitulorum is wildly spread on the Qinghai Tibetan plateau, China by fecal examination. Geographical origin, ages, and fecal consistencies are the risk factors associated with T. vitulorum prevalence by logistic regression analysis. Molecular detection and phylogenetic analysis of ND1 gene of T. vitulorum indicated that T. vitulorum in the yak calves on the Qinghai Tibetan plateau are homologous to preveiously studies reported.
