Objective To investigate the value of combined use of laparoscopic cholecystectomy(LC)and duodenoscopic procedures in the treatment of gallbladder stones with common bile duct stones.Methods We retrospectively analyzed clinical data of 164 cases of gallbladder stones with common bile duct stones treated with laparoscopic cholecystectomy + endoscopic sphincterotomy(EST)from January 2003 to December 2007.Results All the cases underwent ERCP and endoscopic sphincterotomy(EST)followed by LC.In the 164 cases,196 bile duct stones were extracted from 155cases with a success rate of 94.5%.The procedures were unsuccessful in 9 cases,and among them,4 cases had stricture of bile duct more than 2 cm in length,and 5 cases had impacted stones that precluded passage of the guide wire.After EST,6 of the 155 cases had the complication of mild acute pancreatitis and LC was performed after its treatment.The success rate of LC was 96.5% and the average hospital stay was(11?4)d.Conclusions The combined use of EST and ERCP before LC is effective in treatment of gallbladder stones with common bile duct stones,and has broadened the utilization of minimally invasive treatment for bile duct diseases.

The method for preparation of models of myocardial ischemia in rats have been well described in the literature, are of practical value and have been chosen by many researchers for pharmacological studies of drugs for human diseases.However, there is still lack in some details of their operability and practicability.We re-selected the coronary artery ligation site, simplified the procedures and improved the experimental method for preparation of the models, and made satisfactory result.In this paper we will review the selection of method for preparing myocardial ischemia model in rats, describe some details of the surgical operation, explored the influencing factors and so on, and provide a reference for selecting most appropriate animal model in research.

Objective To identify risk factors associated with the severity of acute kidney injury (AKI) in-duced by crush syndrome and whether the patient required hemodialysis (HD). Method A retrospective study was designed. Within 19 days after the Chinese Wenchuan earthquake (May 12, 2008), 63 victims (33 men, 30women) of 2139 cases were hospitalized at Mianyang Central Hospital (Siehuau, China) because of crush syn-drome caused by crush injuries. The patients with renal dysfimcfion before the earthquake were excluded. Totally 63 patients with AKI associated with crush syndrome were included in this study and were divided into two groups: group 1, 25 patients, requiring HD (when urine volume <250 mL/d;serum potassium> 6 mmol/L) ; and group 2, 38 patients, without HD. The following data were collected retrospectively for all patients: (1) epidemiological parameters: age, gender, race, time under the rubble, liquid treatmem before being rescued; (2) clinical param-eters: blood pressure, body area crushed, amputation, fasciotomy, blood transfusion, quantity of fluid infusion, urine output in the first 24 hours; (3) initial laboratory data: complete blood count, urine analysis, serum chem-istry, arterial blood gas analysis. Comparisons between the two groups were made using SPSS 10.0. The quantita-tive data and categorical data were analyzed using t tests and χ2 tests, respectively. P -values < 0.05 were consid-ered to indicate significant differences. The significant variables were entered into logistic regression models to de-termine the risk factors for the severity of AK1 in patients with crush syndrome and whether the patient required HD. Results Four significant risk factors with P -values < 0.05 were identified: fasciotomy, cystatin C (Cys C)level, myoglobin (MB) level and lactic acidosis. The odds ratios (95% confidence intervals) were 8.641 (3.027~76.479), 6.956 (3.027~76.479), 5.379 (3.027~76.479) and 4.833 (2.569~32.764), respectively. Conclusions In addition to urine output and potassium levels, we found that four risk factors, namely faseiotomy, Cys C and MB levels, and lactic acidosis, were significanfly associated with the severity of AKI and whether the patient required hemodialysis.

Objective To survey the resistance profile of clinical isolates to antibiotics across the hospitals in Dongguan,Guangdong Province during 2015.Methods Kirby-Bauer method or automated system was used to test the susceptibility of clinical isolates to selected antimicrobial agents.Results were analyzed according to CLSI 2015 breakpoints.The susceptibility data were analyzed using WHONET 5.6 software.Results A total of 29 665 strains of microorganisms were isolated,of which gram positive cocci accounted for 32.1% (9 509/29 665) and gram negative bacilli accounted for 67.9% (20 156/29 665),respectively.The prevalence of methicillinresistant Staphylococcus was 23.3% (705/3 024) in S.aureus and 43.6% (1 054/2 419) in coagulase-negative Staphylococcus.No vancomycin-resistant staphylococcal strain was found.ESBLs-producing strains accounted for 36.4% (2 554/7 020) in E.coli and 24.5%(792/3 227) in Klebsiella isolates.The prevalence of carbapenem-resistant Enterobacteriaceae was 0.2% (30/13 077).The prevalence of carbapenem-resistant Pseudomonas aeruginosa (CRPA) and carbapenem-resistant Acinetobacter baumannii (CRAB) was 16.0% (500/3 116) and 53.9% (827/1 533),respectively.The prevalence of penicillin-resistant S.pneumoniae (PRSP) strains was 10.1% (142/1 404).Beta-lactamase was produced in 30.6% (276/902) of the H.influenzae strains.The prevalence of vancomycin-resistant Enterococcus (VRE) strains was 0.7% (10/1 441).Conclusions Periodic surveillance of antimicrobial resistance is valuable for rational antimicrobial therapy,formulation of treatment guidelines and infection control and prevention measures,as well as preventing the spread of drug-resistant strains.

Monitoring blood glucose level timely and accurately and management of glucose level is crucial for the treatment of diabetes and the prevention of diabetic complications. Glycated albumin is one of the important biomarker to evaluate the fluctuation of blood glucose level, which has been widely used in clinic. To understand the advantages and limitations of the glycated albumin in monitoring glucose level will contribute to its better application in clinic.
