Objective To investigate the effect of trimetazidine postconditoning on myocardial cell apoptosis in acute ischemia-reperfusion injury in rats.Methods 40 healthy adult Wistar rats were randomly assigned to Sham-operated group,MIRI group(I/R group),trimetazidine group and ischemic postconditioning group(IPOC group).The left anterior descending coronary artery of rat was ligated and the acute myocardial ischemia-reperfusion injury model was established.After that,ultrastructural changes of apoptotic myocardial cells were observed under electron microscope,and apoptotic cells were detected under optical microscope.The expressions of the Bcl-2,caspase-3 apoptosis related proteins were determined.Results ① The degree of ultrastructural injury of apoptotic myocardial cells was mild and basically the same in trimetazidine group versus IPOC group,and had a significant improvement as compared with I/R group.② The degree of myocardial apoptosis was basically the same in trimetazidine versus IPOC group,and lighter than in I/R group.③ Bcl-2 protein expression levels were(61.9 ± 2.9) ％,(21.4 ± 3.2) ％,(46.8 ± 3.5) ％ and (49.7 ± 3.1) ％,and caspase-3 protein expression levels were(38.1±4.5) ％,(72.8±5.7) ％,(47.2±5.1) ％ and(39.8 ±4.6)％ in Sham-operated group,I/R group,trimetazidine group and IPOC group respectively.Compared with I/R group,the expression of Bcl-2 protein was increased obviously,while the expression of easpase-3 protein was decreased in trimetazidine group and IPOC group.But there were no significant differences in the protein levels of Bcl-2 and caspase-3 between trimetazidine group and IPOC group(both P＞0.05).Conclusions Trimetazidine postconditoning can inhibit the myocardial cell apoptosis in acute ischemia-reperfusion injury in rats,and has a protective effect on myocardial cells.

Objective To investigate the safety and feasibility of laparoscopic pylorus-preserving pancreaticoduodenectomy.MethodsThe data of 59 patients with laparoscopic pancreaticoduodenectomy in Shangjin hospital of West China hospital of Sichuan University from January 2014 to December 2015 were analyzed retrospectively.The general data,operative time,estimated blood loss,conversion rate,time to liquid diet,postoperative hospital stay and complications were analyzed.Results The laparoscopic pylorus-preserving pancreaticoduodenectomy were successfully performed in 56 cases,the successful rate was 94.9%,the other 3 patients were converted to laparotomy for superior mesenteric vein/portal vein involvement.The operative time was 255~510 minutes,with mean operative time (384±145) minutes,the intraoperatve blood soss was 50~800 mL,with mean estimated blood loss (148±28)mL,the time to liquid diet was 1.0~4.0 days,with average time (3.2±1.1)days,the postoperative hospital stay was 5.0~53.0 days,with average time (10.3±2.6)days.After surgery,16 cases suffered from complication,the rate was 27.1%.The most common complication was pancreatic fistula which occurred in 13 cases including 12 cases of grade A and 1 case of grade pancreatic fistula.No grade C pancreatic fistula occurred in this series.Six patients suffered from delayed gastric emptying.One patient suffered from bile leakage.Conclusion Laparoscopic pylorus-preserving pancreaticoduodenectomy was safe and feasible.Pylorus-preserving does not increase the incidence of delayed gastric emptying.

Objective Experimentally to investigate the changes in vasospastic canine basilar arteries. Methods Vasospasm of basilar arteries was induced by double-injecting autologous blood into the brain cisterns. 28 adult mongrel dogs of both genders served as the subjects, of them 20 involved in experimental group and accepted the PTA treatment and the other 8 doges were in negative control group without any treatment. PTA was performed by a single inflation of balloon for 10 seconds at a peak pressure of 2.0 atmospheres. Angiography was re-performed at 30 day, 90 day and 300 day following PTA, respectively. The histologic changes were then evaluated using light and electron microscopy. Results Caliber of basilar arteries of all canines decompressed obviously, from 1.3 mm to 0.8 mm. In test group, PTA succeeded in 15 ones, with caliber of vasospastic basilar arteries enlarged obviously after PTA ( P

OBJECTIVE: To discuss the clinical characteristics of bilateral bronchial foreign body in children, increase the curative rate and reduce the complications. METHOD: The clinical data of 35 cases with bilateral bronchial foreign body in children were retrospectively analysed, including surgery, key surgery points, and postoperative combined therapy. RESULT: The foreign bodies of all cases were removed under intravenous general and tropical anesthesia without complications. CONCLUSION The bilateral bronchial foreign body is a serious case, the timely and effective treatment can lower the mortality rate and postoperative complications. The children lack of oxygen for a long time before and in operation should be give comprehensive therapy, for example: sedation and hyperbaric oxygen.

Objective To analyze the risk factors of respiratory depression occurring during recovery period in patients after having undergone general anesthesia and laparoscopic operation.Methods A total of 374 patients after general anesthesia and laparoscopic surgery admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2015 to June 2016 were enrolled, they were divided into with or without the incidence of respiratory depression two groups by whether or not respiratorydepression, with the incidence of respiratory depression group 52 cases, without the incidence of respiratory depression group 322 cases. The patients' gender, age, body mass index (BMI), operation time, anesthesia maintenance mode, artificial airway mode, operative type and medication used in operation, intra-operative hypotension presence or absence, and type of operation were recorded. Univariate and multivariate logistic regression analyses were used to evaluate the risk factors of respiratory depression occurring in the recovery period after general anesthesia; receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of age, intraoperative medication, and age combine with intraoperative medication respectively in the occurrence of respiratory depression during recovery period after general anesthesia and lapatoscopic operation.Results Univariate analyses showed that there were no statistical significant differences in gender, BMI, operation time, anesthesia maintenance mode, artificial airway mode, intra-operative hypotension presence or absence, type of operation, etc. compared between patients with and without the incidence of respiratory depression groups (allP > 0.05); while the differences were statistically significant in age and drug used in the operation (dezocine, flurbiprofen, dexmedetomidine or dezocine combined with dexmedetomidine, allP < 0.05). Multivariate analyses showed that age and medication used in operation were the independent risk factors for the occurrence of respiratory depression during the anesthesia recovery stage (P values being 0.000, 0.002 respectively). ROC curve showed that age, intra-operative medication and age combine with intraoperative medication respectively had certain predictive value for the occurrence of respiratory depression during the recovery period after general anesthesia and laparoscopic surgery, the area under the ROC curve (AUC) of age combine with intraoperative medicationfor prediction of occurrence of respiratory depression during recovery period after anesthesia and laparoscopic surgery was significantly larger than that of single age or single intraoperative medication (0.826 vs. 0.668, 0.750,P < 0.01), 95% confidence interval (95%CI) of age, intraoperative medication and age combined with intraoperative medication were 0.598-0.738, 0.670-0.830, 0.764-0.888, the sensitivity, specificity and accuracy rate of age combine with intraoperative medication were 53.8%, 94.4% and 88.8%, respectively.Conclusion Elderly patients undergoing general anesthesia and laparoscopic operation and dezocine, dexmedetomidine or dezocine combined with dexmedetomidine being applied in the laparoscopic operation are more easily associated with incidence of respiratory depression during recovery period of anesthesia.
