Objective To systematically compare propofol and isoflurane for myocardial protection in patients undergoing coronary artery bypass grafting (CABG).Methods Electronic databases were searched for randomized controlled clinical trials comparing propofol and isoflurane for myocardial protection in patients undergoing CABG.Data which were extracted independently by two reviewers included the general data of patients,premedication,induction of anesthesia and anesthetics applied during maintenance of anesthesia,level of cardiac troponin I (cTnI) before operation and at 6,12,24 and 48 h after operation,requirement for positive inotropic agents during operation,and development of myocardial infarction within 24 h after operation.Meta-analysis was conducted using Review Manager 5.0.2.Results Sixteen randomized controlled clinical trials involving 794 patients were included in this meta-analysis.The patients were divided into 2 groups:propofol group (n =405) and isoflurane group (n =389).There were no significant differences between the two groups in the plasma concentration of cTnI after operation,incidence of myocardial infarction within 24 h after operation,and requirement for positive inotropic agents during operation (P ＞ 0.05).Conclusion There is no significant difference between propofol and isoflurane for myocardial protection in the patients undergoing CABG.

OBJECTIVE:To explore the reasons,occurrence mechanisms,as well as prevention methods for complications following cerebrovascular stent implantation.METHODS:A computer-based online search was performed by the first author.The databases of Medline and CNKI were searched with year's limitation of 1989-2009.According to the inclusive and exclusive criteria,the documents were screened,collected and evaluated from the following aspects:treating progress of cerebrovascular stent implantation;category and biocompatibility of cerebrovascular stent;as well as occurrence and prevention methods for complication following cerebrovascular stent implantation.RESULTS:A series of complications,such as carotid sinus response,hyper-perfusion syndrome,cerebral anglo spasm,bleeding at puncture locus,thrombosis,restenosis,as well as cerebral ischemia,would occur following cerebrovascular stent implantation.The complications were difficult to eliminate,but should be avoided by selecting correct implanting cases,elevating operator's proficiency,enhancing understanding of complications,obeying perioperative management,as well as correctly and in-time treatment.Polymer stent,coating stent,and drug eluting stent presented superior biocompatibility to metal stent,which could prevent restenosis following implantation.CONCLUSION:Cerebrovascular stent implantation is one of the main treatments for cerebrovascular disease.Polymer stent,coating stent,and drug eluting stent exhibit excellent biocompatibility.The complications associate to stent implantation are preventable and remediable via sufficient preoperatively preparation,exactly operation and perioperative management.

Objective To investigate the short-term efficacy and safety of gefitinib combined with dendritic cells-cytokine induced killer (DC-CIK) cells in the treatment of advanced lung adenocarcinoma.Methods Fifty patients with lung adenocarcinoma who in previous had underwent radiotherapy and first-line chemotherapy failure received DC-CIK in combination with gefitinib treatment,blood count changes,imaging data,carcinoembryonic antigen and changes in the quality of life before and after treatment were compared and evaluated.Results DC-CIK could improve effectively and relieve bone marrow suppression response after chemotherapy and significantly increase the WBC content of blood (P ＜ 0.01).After treatment,the tumor carcinoembryonic antigen (CEA) was significantly lower in patients (P ＜ 0.01).Fifty cases of patients in complete remission (CR) were 0 cases,partial remission (PR) were 24 cases,stable disease (SD) were 17 cases and progression (PD) were 9 cases,and the response rates (RR) were 48％;The quality of life of patients was significantly improved (P ＜ 0.05).Common adverse reactions were rash,diarrhea,chill and fever,but mild symptoms could be relieved after symptomatic treatment.Conclusions Gefitinib with autologous DC-CIK cell infusion second-line treatment of advanced lung cancer have a certain short-term efficacy,without significant adverse reactions.Gefitinib with autologous DC-CIK cell therapy can mitigate the response of bone marrow suppression in patients with advanced lung cancer and improve the quality of life of patients.Long-term effect remains to be investigated.

AIM:To observe the secretion of vascular endothelial growth factor(VEGF)when adenovirus induced VEGF165(AdVEGF165)gene transferred into neonatal cardiomyocytes in vitro,and to investigate the impact on heart function after transplanted the transferred cardiomyocytes into infarct myocardium in rats.METHODS:Neonatal cardiomyocytes were cultured in vitro and labeled with BrdU,then transferred by AdVEGF 165.ELISA was applied to assay the expression and secretion of VEGF.Wistar rats,in which left descending branch of coronary artery was ligated,were randomly divided into four groups and transplanted into MI area with transferred cardiomyocytes(group Ⅰ),untransferred cardiomyocytes(group Ⅱ),AdVEGF 165(group Ⅲ)and culture medium(group Ⅳ),respectively.The echocardiograph was applied to evaluate the heart function before and after cell transplantation.Then the rats were executed and the hearts were harvested for histological(hematoxylin-eosin)and immunohistological(anti-BrdU dyeing)examinations.The vessels were also counted in injected area.RESULTS:ELISA indicated that the expression and secretion of VEGF in groupⅠwere higher than those in the rest(P

Objective To observe the effect of Juli Sanjie Pill(JSP) on estrogen receptor(ER)? and ER? expression in the myometrium and hysteromyoma tissue,and to explore the correlation of ER? and ER? expression levels with the incidence of hysteromyoma. Methods Forty hysteromyoma patients were divided into two groups: 20 patients with operative indications after oral use of JSP and asking for operation,were enrolled in the treatment group,and other 20 patiens without mediation of medicine but asking for operation were in the control group.The ER? and ER? expression levels in hysteromyoma tissue and the surrounding normal myometrium of the two groups were detected by radioimmunoassay.Results There presented the expression of ER? and ER? in the hysteromyoma tissue and the surrounding normal myometrium of the two groups,and the levels in the hysteromyoma tissue were higher than that in the myometrium(P0.05).Conclusion The incidence of hysteromyoma is correlated with the local expression of ER? and ER? in the uterus.The therapeutic mechanism of JSP for hysteromyoma is probably related with the decrease of ER? and ER? expression levels in hysteromyoma tissue and with the decrease of ER? level in the surrounding normal myometrium.
