Objective:To evaluate the short-term effect of robotic pancreaticoduodenectomy (RPD) and laparoscopic pancreaticoduodenectomy (LPD) in the treatment of ampullary and periampullary tumor systematically.Methods:A systematic search of the PubMed, Embase and Cochrane library database using the key words "pancreaticoduodenectomy, duodenopanreatectpmy, whipple, laparoscopic, robotic, Da Vinci" . A systematic search of the Sinomed, Wangfang, VIP and CNKI databases including the key words "胰十二指肠切除" , "腹腔镜" , "机器人" , "达芬奇" . To investigate the differences of the conversion rate of laparotomy, incidence of postoperative complications, and the postoperative hospital stay between the RPD group and the LPD group. The software RevMan5.3 was used in this meta-analysis.Results:A total of 4 retrospective cohort studies and 1 001 patients were included in this meta-analysis, including 451 patients in the RPD group and 550 patients in the LPD group. The results of the meta-analysis showed that there were significant differences between RPD group and LPD group for the conversion rate laparotomy ( OR=0.35, 95% CI: 0.24-0.50, P<0.05). There were no significant differences between RPD group and LPD group for the incidence rate of overall complication( OR=1.23, 95% CI: 0.95-1.58, P>0.05), hemorrhage ( OR=0.71, 95% CI: 0.50-1.00, P>0.05), pancreatic fistula ( OR=1.09, 95% CI: 0.80-1.49, P>0.05), delayed gastric empty ( OR=0.81, 95%CI: 0.57-1.14, P>0.05) and hospital stay after surgery ( WMD=-2.87, 95% CI: -1.44-1.70, P>0.05). Conclusions:RPD is as safe as LPD, with the same complication rate. Therefor it is worthy for further application in medical institutions with relevant conditions.

Objective To investigate the drug resistance of bacteria clinically isolated from Yuyao people's hospital and its relationship with antibiotic consumption, in order to provide basis for rational use of antibiotics in clinic.MethodsA total of 3178 strains of bacteria were detected in our hospital from the third quarter of 2015 to the second quarter of 2016.The drug resistance of bacteria, the consumption of antibacterial agents in each quarter, and their relationships were analyzed.ResultsThe major isolated bacteria was gram-negative bacteria, among which constituent ratio of Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa ranked the top 4.Gram-negative bacteria's resistance rates of several antibiotics were positively correlated with the utility rate of quinolones, and also had a different degree of positive correlation with the use of beta lactamase/inhibitor, aminoglycosides and carbapenems.Staphylococcus were the mainly gram positive bacteria, whose resistance rates to penicillin, ciprofloxacin, levofloxacin and erythromycin were positively correlated with the usage of the same type of antibiotics.ConclusionBacterial resistance rates are closely associated with the consumption of antimicrobials.Selecting antibacterial agents reasonably according to the results of drug susceptibility test is important to control the drug resistance of bacterial.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.
