Objective: To systemically evaluate the efifcacy and safety of coronary artery bypass grafting (CABG) without stopping pre-operative aspirin administration for anti-platelet therapy in relevant patients. Methods: The computer searching including Cochrane Library (Issue 2, 2014), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP was conducted to collect the randomized controlled trial (RCT) for CABG without stopping pre-operative aspirin administration from the data base establishment until 2014-07. There were 2 reviewers identiifed the literatures independently according to inclusion, exclusion criteria, and extracted the information, evaluated the quality of assessment methods, then meta-analysis was performed by RevMan 5.2 software. Results: A total of 8 RCT studies including 1945 patients were enrolled. The meta analysis showed that compared with stopping pre-operative aspirin administration, the patients without stopping pre-operative aspirin had obviously increased post-operative bleeding drainage as MD=235.97,P=0.01, re-operation for bleeding as OR=2.4,P=0.0005 and fresh frozen plasma transfusion requirement as MD=0.79,P<0.0001. While the packed red blood cell (PRBC) transfusion requirement as MD=0.66, P=0.05, platelet transfusion requirement as MD=0.99,P=0.25, the incidence rate of post-operative myocardial infarction as OR=1.03,P=0.90 and post-operative mortality (OR=1.24,P=0.56) were similar between two conditions. Conclusion: CABG without stopping pre-operative aspirin administration may increase the post-operative bleeding,transfusion and re-operation for bleeding; low dose aspirin administration before CABG needs further investigation to solve the above problems in clinical practice.

Objective To review systemically the safety of endoscopic vessel harvesting ( EVH ) in coronary artery bypass grafting (CABG). Methods By searching documentations in the Cochrane Library , Pubmed, Medline,EMbase, CBM, CNKI, Wanfang database , and Weipu database , with no limits for language , a random-controlled meta-analysis was assembled for evaluating the safety of EVH of great saphenous veins in CABG .The retrieval deadline of these databases was September 2013.Two evaluators were in charge of selecting , extracting , and assessing the quality of methodology in all these articles according to extract criterion independently.The RevMan 5.2 was used for meta-analyse. Results The whole test included 12 RCTs and 1510 patients, comprising of 857 patients with EVH and 653 patients with traditional harvesting .As compared with traditional group , the EVH group showed lower rate of postoperative incision infection [OR=0.24, 95%CI:0.16-0.36, P<0.0001], less postoperative pain [OR=-1.06, 95%CI:-1.26--0.86, P<0.0001], and less postoperative complications [OR=0.28, 95% CI:0.19-0.42, P<0.0001].There were no significant differences between the two groups in hospital stay [WMD=0.17, 95%CI:-0.22-0.56, P=0.40] and mortality [OR=0.88, 95% CI:0.30 -2.64, P=0.82]. Conclusion EVH factually reduces trauma in CABG, postoperative infection rate , postoperative pain , postoperative complications , and hospital stay ,being applicable for high risk patients .

In order to take advantage of the model of rat in cardiovascular research, get rid of the influences of the nerve and humoral factors to cardiac function, fix the cardiac load state, and obtain such valuable indices as ejection fraction, left ventricular volume, etc., an isolated working heart perfusion system was set up to observe the changes of the cardiac systolic and diastolic function, ventricular compliance and pumping function. The results of a series of experiments indicated that the stability and responsibility of this perfusion model are satisfactory. The results of coronary ligation and reperfusion were correspondent to those of other authers. This perfusion system can be used in the studies of physiolgoy, biochemistry, pharmacology and pathophysiology.

Cardiac functions were measured after the pretreatment. The results indicated that: 1. arterial blood pressure, cardiac output, stroke volume and heart rate had not changed significantly; 2. left ventricular spike pressure had not changed but ?dp/dtmax decreased by 14%(Control 728.88?38.39 KPa/s, ADM 626.77?25.59 P

Objective To investigate the efficacy and significance of endoscopic sphincterotomy(EST)and endoscopic nasobiliary drainage(ENBD)combined with the continuous blood purification(CBP)in the treatment of severe acute pancreatitis(SAP).Meth-ods The clinical data of 179 patients with SAP treated in our hospital over a period of ten years were retrospectively analyzed.The cases were divided into four groups according to the treatment methods.The conventional group was treated with the routine meth-od,the CBP group received the CBP therapy combibed with routine methods,the endoscopic group was given EST and ENBD on the basis of the routine methods and the combined group was treated with CBP,EST and ENBD.The patients′vital signs,WBC,CRP, APACHE Ⅱ score,abdominal signs change,incidence of complications,mortality and hospitalization days were compared among 4 groups.Results Compared with the conventional group,the clinical indicators,WBC,CRP,APACHEⅡ scores,blood amylase lev-el,incidence of local complications,mortality and hospitalization days in the rest three groups were decreased significantly(P<0.05),the total effective rate of abdominal signs relief was significantly increased(P<0.05);compared with the rest groups,the to-tal effective rate of abdominal signs relief in the combined group was increased(P<0.05),the blood amylase level,incidence of local complications and hospitalization days were decreased significantly(P<0.05),the mortality was significantly lower than that in the conventional group(P<0.05),however there was no difference between the CBP group and the endoscopic group(P>0.05).Con-clusion CBP combined with EST and ENBD in treating SAP has the active and effective role for improving the disease condition, reducing complications and the mortality,and shortening the hospitalization time.

Objective To analyze the role of sleep quality (SQ) in quality of life (QOL) ofheroin addicts receiving methadone maintenance treatment (MMT).Methods A total of 603 heroin addicts completed the socio-demographic questionnaire,Pittsburgh Sleep Quality Index (PSQI),and the World Health Organization'sQuality of Life Questionnaire-Brief Version (WHOQOL-BREF).Hierarchical Multiple Linear Regression was used to examine the unique contribution of SQ in the explanation of QOL.Results The overall unique contributions of the seven components in PSQI,measured by △R2,ranged from 0.139 to 0.216,which could account for 41.3％ ～55.7％ of the total explainable variance in the four domains of WHOQOL-BREF.Conclusion SQ is an important predictor of Q0L in heroin addicts receiving MMT.QOL can be improved through the intervention of low SQ.

Objective To analyze the hypothalamic-pituitary-adrenal axis function in type 2 diabetes mellitus(T2DM) patients combined with depression with different courses.Methods Forty T2DM without depression patients (T2DM without depression group) and 42 T2DM combined with depression patients (T2DM combined with depression group) were divided into 3 groups according to the courses:＜ 5years,5-15 years,＞ 15 years.Thirty healthy person were selected as control group.The levels of serum adrenocorticotropic hormone (ACTH),cortisol (Cor),fasting blood glucose (FPG),glycosylated hemoglobin (HbA1c),24 h urinary-free cortisol (UFC) were determined at 8:00 Am.Results The levels of serum ACTH,24 h UFC in T2DM without depression group were higher than those in control group [(241.7 ±132.6) pg/L vs.(174.1 ± 108.2) pg/L and (96.67 ± 15.92) μg vs.(76.04 ±24.60) μg],and there were significant differences (P ＜ 0.05 or ＜ 0.01).There were no significant differences in the levels of serum ACTH,Cor,24 h UFC among ＜ 5 years,5-15 years,＞ 15 years in T2DM without depression group (P＞0.05).The levels of serum Cor,24 h UFC in T2DM combined with depression group were higher than those in T2DM without depression group and control group,and there were significant differences (P ＜ 0.01),but compared with those in T2DM without depression group with the same courses,only ACTH was different in ＜5 years (P ＜ 0.01),Cor,24 h UFC was different in ＞ 15 years (P ＜ 0.01).There was significant difference in the level of serum ACTH between ＜ 5 years and 5-15 years,＞ 15 years in T2DM combined with depression group (P ＜ 0.01),Cor had no difference among different courses (P ＞ 0.05),24 h UFC had difference between ＞ 15 years and ＜ 5 years,5-15 years (P＜ 0.01 or ＜ 0.05).In T2DM without depression group,the level of serum Cor was positively correlated with FPG (P ＜ 0.01),the level of serum ACTH was positively correlated with FPG (P ＜0.05).In T2DM combined with depression group,the level of serum Cor was positively correlated with FPG,HbA1c (P ＜ 0.01),the level of serum ACTH was no relationship with others,the level of serum 24 h UFC was positively correlated with FPG,HbA1c (P＜ 0.01).Conclusion With the prolonged courses of diabetes,the function of hypothalamic-pituitary-adrenal axis gets worse in T2DM patients combined with depression.

Epstein-Barr virus( EBV )is a ubiquitous human gamma-1 herpesvirus,which is associated with human malignancies,such as nasopharyngeal carcinoma,Burkitt's lymphoma and Hodgkin lymphoma.Based on the polymorphism of amino acids in the polymorphic region of EBV genome,it can be classified into different subtypes/variants.By now,whether the subtypes/variants of EBV preferentially is associated with particular malignancies or represent geographical polymorphism remains controversial.This review summarized the literature on sequence variation in EBV genes,focusing on LMP-1,EBNA-1,and BZLF-1 and their distribution by geography and disease.
