Between January 2011 and December 2011,86 patients undergoing operation for anorectal disease were randomized in a double-blind manner to receive a mixed injection of methylene blue,ropivacaine and sodium chloride (observation group,n =43) or traditional analgesic methods (control group,n =43).Patients in observation group had less visual analog scale (VAS) scores of pain at 6-48 h postoperation than control group (P ＜0.05).The scores had no significant difference at 72 h postoperation between two groups (P ＞ 0.05).The total postoperative complications (8,19％) and hospitalization duration [(5.3 ± 2.2) days] in observation group were significantly less than those [15,35 ％ and (6.4 ±1.7) days] in control group (P ＜ 0.05).A mixed injection of methylene blue and ropivacaine intraoperatively can relieve the postoperative pain of patients with anorectal disease and reduce the incidence of postoperative complications and the duration of hospitalization.

Objective To provide guidance for patients and enhance their trust in the hospital by achieving openness and transparency in medical fees. Methods The modular structure of the three-tiered process was employed and various information machines, inquiry devices and doctors' workstations were connected to the Hospital Information System to form an integrated inquiry system of hospital-wide coverage. Results The Hospital Information System, with its versatile functions, easy operation, strong compatibility and good reliability, could provide patients with accurate information and more convenience. Conclusion The Hospital Information System can meet different needs of all patients.

[Objective] To explore whether diabetes mellitus (DM) can influence the early bacterial translocation (BT) and progression of acute necrotizing pancreatitis (ANP) for guiding the early clinical treatment.[Methods] 35 Wistar male rats were randomly allocated to 4 groups,Group ANP associatcd with DM (DM+ANP,n =10):DM underwent induction of ANP;Group DM (n =10):DM underwent laparotomy with only manipulation of the pancreas and duodenum;Group ANP (n =10):non-DM underwent induction of ANP;Group sham operation (SO,n =5):non-DM underwent SO.After 12 h of the induction of ANP or laparotomy,the following parameters were analyzed:bacterial culture and identification of portal vein blood,mesenteric lymph nodes (MLNs),pancreas and liver,and calculate the total incidence of BT;serum amylase and endotoxin levels of portal vein blood;histological assessment of pancreas and ileum lesions.[Results] All animals except 3 in group DM+ANP (mortality rates:30％) and 1 in group ANP (mortality rates:10％) survived the experiment.The total incidence of BT was 23/28 (82.1％) in group DM+ANP whereas 16/36 (44.4％) in group ANP (P =0.002).Gram-positive bacteria were 17/23 (73.9％),3/16 (18.8％) in group DM+ANP and group ANP,respectively (P =0.001).Amylase activity (2302 ± 346) U/L in group ANP increased significantly (P =0.000) compared with other groups.However,group DM+ANP (501 ± 142) U/L decreased significantly (P =0.001) in comparison to group SO.Regarding to endotoxin concentrations and the severity of pancreas and ileum lesions,group DM + ANP increased significantly compared with group ANP,group DM and group SO (P ＜ 0.05).[Conclusion] Gram-positive bacteria translocates more frequently than Gram-negative bacteria in the early period of DM+ANP rats.DM aggravates the progression of ANP and increases early bacterial translocation,endotoxemia and severity of pancreas and ileum lesions.
