Objective To evaluate the efficacy of different doses of ulinastatin for prevention of insulin resistance in the patients undergoing partial hepatectomy.Methods Sixty patients of both sexes,aged 33-71 yr,weighing 44-70 kg,of ASA physical status Ⅰ or Ⅱ,scheduled for electivepartial hepatectomy,were randomly assigned into 3 groups (n =20 each) using a random number table:control group (group C),low dose of ulinastatin group (group UL) and high dose of ulinastatin group (group UH).Before induction of anesthesia and at the beginning of operation,ulinastatin 2 500 U/kg and 5 000 U/kg (in 20 ml of normal saline) were injected intravenously in UL and UH groups,respectively.The equal volume of normalsaline was given instead of ulinastatin in group C.Before skin incision,before removal of the liver,after removal of the liver,and after closure of the abdominal cavity,blood samples were taken from the right internal jugular vein for determination of plasma glucose,insulin and glucagon concentrations.Insulin sensitivity index was calculated.Results Compared with group C,insulin sensitivity index was significantly increased,and the plasma glucose and insulin concentrations were decreased in UL and UH groups.Conclusion Ulinastatin 2 500 U/kg injected intravenously before induction of anesthesia and at beginning of operation can effectively prevent insulin resistance in the patients undergoing partial hepatectomy.

Objective To investigate the clinical curative effect of“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine for acute soft tissue sprain of the ankle.Method A total of 90 patients with acute soft tissue sprain of the ankle from emergency department of WangJing Hospital, CACMS were recruited from July 2013 to April 2014 and randomly divided into two groups with 45 patients in each. The patients in the treatment group were treated with the court manipulation, plaster and Chinese herbs washing, and those in the control group were only treated with cast immobilization. The clinical curative effect was evaluated using Baird-Jackson score system(excellent: 96-100; good: 91-95; fair: 81-90; poor: 0-80).Result At the second, third week after treatment, the excellent/good rates in the treatment group were significantly higher than those in the control group(at week 2: 73.3%vs. 44.4%;χ2=11.468,P<0.01; at week 3: 86.7%vs.60.0%;χ2=6.875,P<0.05). At week 2 and 3, Baird-Jackson scores in the treatment group(87.41±14.12, 93.16±9.51)and in the control group(76.32±11.41, 82.54±9.22)were significantly higher than those before treatment(treatment group: 72.11±12.61; control group: 71.67±13.12, allP<0.05); at week 3, Baird-Jackson score in the treatment group were significantly higher than that in the control group(P<0.05).Conclusion“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine can increase Baird-Jackson score and aid recovery of the ankle function in patients with acute soft tissue sprain of the ankle.

Objective To evaluate bile duct drainage with ureteral catheter through cystic duct in laparoscopic common bile duct exploration followed by primary duct closure (LCBDEPDC) and posto laparoscopic endoscopic stone extraction treatment of extrahepatic bile duct stones.Methods The clinical data of 116 cases of extrahepatic bile duct stones were retrospectively analyzed.Patients were divided into 2 groups: 57 patients with dilated common bile duct were in group A treated with laparoscopic common bile duct exploration followed by primary duct closure and via cystic duct ureteral catheter biliary drainage.While in group B (59 patients) with normal calibre of the common bile duct, the procedures was laparoscopic cholecystectomy + via cystic duct ureteral catheter biliary drainage and postoperative endoscopic stone extraction.Results Procedures were successful in both the two groups.There was no postoperative pancreatitis and biliary leakage complications.The catheter was withdrawn in 6-9 d in group A postoperative hospitalization time was (8.5 ± 2) d.The catheter was withdrawn in 2-8 d in group B after endoscopic stone extraction.Postoperative hospitalization time was (7.6 ± 3) d.No complications occurred in both two groups relating extubation.Conclusions Bile duct drainage using the ureteral catheter via cyst duct after LCBDEPDC and endoscopic stone extraction treatment of extrahepatic bile duct stones effectively prevent postoperative pancreatitis, biliary leakage and bile duct stricture.

BACKGROUND: The number of patients undergoing total knee replacement due to severe gouty arthritis is increasing rapidly in recent years, and the ages of patients also present younger and younger. However, its clinical efficacy remains controversial, and it is lack of retrospective systematic analysis. OBJECTIVE: To assess the clinical efficacy of total knee replacement for severe gouty knee arthritis from several aspects, such as pain, function, quality of life and complications. METHODS: From January 2006 to January 2015, 17 patients (20 knees) with severe knee gouty arthritis received total knee replacement in Department of Orthopedics of Nanjing General Hospital of Nanjing Military Region of Chinese PLA. They underwent knee joint surface replacement with posterior cruciate ligament, and patel a was not replaced. Posterior stabilized prosthesis was used. Al patients were successful y fol owed up postoperatively. The Hospital for SpecialSurgery Knee Score, range of motion of the knee, Visual Analogue Scale score and SF-36 scale scores were determined before and after replacement and during final fol ow-up. RESULTS AND CONCLUSION: Patients were fol owed up for 1-9 years. No serious complications occurred during and after replacement. The Hospital for Special Surgery Knee Score, range of motion of the knee, Visual Analogue Scale score and SF-36 scale scores were significantly higher after replacement and during final fol ow-up than those before replacement (P < 0.001). X-ray films showed good prosthesis position, satisfactory limb alignment without radiolucent lines or loosing. These findings verified that total knee replacement was considered as the final way to treat the severe gouty knee arthritis; its short-term clinical effect is significant, but systematic anti-uric acid, prevention and treatment of complications, pain control, function exercising, and healthy mood maintenance were needed to get a better long-term clinical efficacy.

Objective To assess the clinical outcomes in patients who underwent laparoscopic primary closure of common bile duct (CBD) with or without transcystic cholangiography and transcystic biliary drainage.Methods From June 2013 to March 2016,we operated on 46 patients who underwent primary closure of common bile duct after laparoscopic choledochotomy (group A).The results were compared with 51 patients who underwent primary closure of common bile duct after laparoscopic choledochotomy together with transcystic biliary drainage (group B) during the same study period.Results There was a significant difference in the incidence of postoperative bile leakage between the two groups.The risk in group A was sig nificantly higher than group B (8.7％ vs 0％,P ＜0.05).The duration of operation in group A was significantly shorter than in group B [(125.3 ± 28.3) min vs (131.3 ± 20.5) min].There were no significant differences in the duration of hospital stay between the two groups [(7.3 ± 2.4) days vs (7.8 ± 1.9) days,P ＞ 0.05].All patients were followed up (range 3 months to 29 months,average 8.4 months).B-ultrasound examination showed no residual bile duct stones and the liver functions were normal.Conclusions Laparoscopic primary closure of common bile duct was possible after choledochotomy.Transcystic cholangiography and transcystic biliary drainage after primary closure of common bile duct were safer and more reli able.
