OBJECTIVE:To establish a method for test of bacterial endotoxin on cefalotin sodium for injection by gel clot.METHODS:Cefalotin sodium for injection was diluted in water for determination of bacterial endotoxin and allocated to sample negative and sample positive controls to determine its maximum noninterference concentration;Then bacterial endotoxins were diluted into solutions of different concentrations with the test solutions,and interference test was carried out by using tachy?pleus amebocyte lysate sensitivity compound nucleus.RESULTS:The maximum noninterference concentration of cefalotin sodium for injection was6.68mg/ml;And cefalotin sodium at the concentration of1.67mg/ml did not interfere with the test for bacterial endotoxins.CONCLUSION:The present method can replace pyrogen test with rabbit for examination of bacterial endotoxin in cefalotin sodium for injection.

The application of radio frequency identification(RFID) and wireless network to neonates' management can effectively avoid occupying infants by mistake.This technology can provide an advanced accessorial instrument in hospital management and upgrade the hospital's professional level.

Thalassemias are a group of inherited disease which is caused by globin gene defects.Identification and quantification of hemoglobin play a very important role for the screening and diagnosis of thalassemia,especially the quantitative analysis of Hb A2 and Hb F.Through past 60 years,the methods for Hemoglobin analysis have been developed from starch gel electrophoresis,paper electrophoresis,cellulose acetate electrophoresis,agarose gel electrophoresis,column chromatography,high-performance liquid chromatography till capillary electrophoresis,Its development closely associates with the research on thalassemia.No matter what kind of methods is chosen,quality control is very important.

Objective To study on the effect of joint surgery of anterior-posterior in the treatment of vitreoretinal diseases complicated with cataract.Methods 78 vitreoretinal diseases patients complicated with cataract(86 eyes)were recruited.All the cases accepted vitrectomy and cataract extraction at the same time.The vision improving situation and postoperative complications of the treatment were analyzed.Results After the joint surgery of anteriorposterior,the visual improvement rate was 88.4％(76/86 eyes),and with unchanged vision in 7.0％,and decreased vision in 4.7％.In 4 patients with decreased vision,1 case was a secondary neovascular glaucoma,and 2 cases were macular hemorrhage or hiatus,1 case was a retinal detachment.In phase Ⅰ,72 eyes did not implant artificial lens,63 eyes(87.5％)got postoperatively improved vision,and 14 eyes implanted artificial lens,and all of them got improved vision(100.0％),and the difference was not statistically significant(P ＞ 0.05).The total postoperative complication rate was 10.5％(9/86 eyes).Conclusion Joint surgery of anterior-posterior in the treatment of vitreoretinal diseases complicated with cataract had determined curative effect and lower complication rate,which deserved further study and widely using.

Objective To understand the total score of health management knowledge demand and self evaluation score of known health management knowledge,in order for hospitals to take more reasonable and effective health management education for patients after discharge.Methods From March to May of 2012,700 patients in a certain three level of first-class general hospital were selected before their discharge,using self-made health management questionnaire for investigation.The total score of health management knowledge demand and score of known health management knowledge among 700 patients with different demographic characteristics underwent statistics.Results After investigation,the results showed that patients with different nationalities,payment method,the average monthly income,family history,residence and intend demonstrated statistical significance in total score of health management knowledge requirement.Patients with different occupation,culture degree and accept frequency showed statistical significance in known health management knowledge.Conclusions According to the current investigation of total score of different health management knowledge demand and known health management knowledge in patients with different demographic characteristics,the hospital should take corresponding adjustment for health management mission to ensure the health management quality of patients after discharge,and improve the health management level of patients after discharge.

Objective To realize the current status of central sterile supply departments(CSSDs)in hospitals,and provide the basis for making improvement measures.Methods Field investigation was adopted to study the resource distribution,personnel structure,and the quality of medical instrument cleaning in 78 hospitals in Chongqing.Re-sults Qualified results of 78 hospitals was 24.36% (19/78),basically qualified rate 52.56% (41/78),unqualified rate 23.08% (18/78);inspection results of different types of hospitals were significantly different(Hc= 16.643,P=0.002),qualified hospitals mainly concentrated on city- and county-level hospitals.Unqualified rate of CSSD con-struction area was 78.21% (n= 61),unqualified rate of personal allocation was 75.64% (n= 59),concentrated man-agement of operating rooms and CSSDs was 52.56% (n= 41),mainly concentrated on city- and county-level hospi-tals;decentralized management accounted for 47.44% (n= 37),58(74.36% )hospitals used repeated cleaning stain-less steel tables for receiving,50% didn’t install automated cleaning machine and drying cabinet,42.31% (33/78) performed manual cleaning,40(51.28% )didn’t equip with water treatment system;12(15.38% )hospitals used patched or worn clothing for packing,47 didn’t equip with hard metal container,37(47.44% )had no heat sealing machine,21(26.92% )had no detection equipment for cleaning quality,41(52.56% )had no low temperature sterili-zation instruments;52(66.67% )hospitals performed biological monitoring on high pressure steam sterilizer.Conclu-sion Clean and disinfection equipments in CSSDs in city- and county-level hospitals are well-appointed,procedures of clean and disinfection are standard,and can achieve the standard of clean quality;while hospitals affiliated to fac-tories and private hospitals are not well-appointed,procedures of clean and disinfection are not standard. Construc-tion of CSSD should be standard,so as to ensure the effectiveness of clean,disinfection and sterilization of surgical instruments.

Aim To investigate the effect of allopurinol and benzbromarone on serum level of uric acid, hepatic xanthine oxidase(XOD) activity and intestinal expression of glucose transporter(GLUT) 2 and 5 in rats with fructose-induced hyperuricemia.Methods Wistar rats were fed with 10% fructose in drinking water for consecutive 8 weeks to induce HUA.Treatment with 5 mg·kg-1 allopurinol or 10 mg·kg-1 benzbromarone were intragastricly administered from 5~8 weeks.Serum level of uric acid and XOD activity in liver were tested.Expression of GLUT2 and GLUT5 in intestine was analyzed by immunohistochemistry staining and Western blot.Results Treatment with allopurinol or benzbromarone significantly decreased the serum level of uric acid in fructose-induced hyperuricemic rats.At the same time, allopurinol treatment significantly reduced the XOD activity in liver and GLUT5 expression in intestine.Nevertheless, benzbromarone treatment did not show inhibitory effect on hepatic XOD activity and intestinal GLUT5 expression.In addition, neither allopurinol nor benzbromarone showed inhibitory effect on GLUT2 expression in intestine.Conclusions Allopurinol decreases serum level of uric acid in fructose-induced hyperuricemic rats.The mechanism is related to reducing XOD-mediated uric acid production in liver, and decreasing GLUT5-mediated fructose absorption in intestine.

Objective To study the therapeutic methods of cholecystic duct stones. Methods A retrospective analysis of the clinical data of 158 cases of cholecystic duct stones treated in the recent 6 years was made. Results 97 of the 158 cases of cholecystic duct stones were removed by open surgical operation and 61 cases by laparoscopic cholecystectomy(LC).In 49 of the 61 cases treated with LC,the cholecystic duct stones were removed together with removal of the gallbladder, and 12 by duodenoscopy after LC. Conclusions One should strive to extract the cholecystic duct stones while removing the gallbladder. If the stones or stone fragments escape into the common bile duct, they could be removed through a choledochotomy at the time of the open operation ,or by postoparative duodenoscopy in cases undergoing LC. The latter method of treatment is associated with minor trauma, quick recovery and definite therapeutic results.
