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:
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 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 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 present our initial experience with robot-assisted laparoscopic prostatectomy (RALP) for complicated cases.Methods:Clinical and pathological data from 4 complicated prostate cancer cases,who underwent RALP from October to November in 2015,were analyzed retrospectively.All the cases were conducted transurethral plasmakinetic enucleation of prostate and hormonal therapy before RALP.Results:All surgeries were done successfully.The age,baseline prostatic special antigen,clinical tumor stage,operation time and estimated blood loss were 58-70 years,6.04-70.15 ng/mL,T2bT3b,210-360 min and 50-250 mL,respectively.No blood transfusion was needed.All surgical margin were negative.Conclusion:Although previous transurethral surgeries and hormonal therapies may increase the difficulty for operations,RALP is still appropriate for the complicated cases of prostate cancer.
