Objective To investigate the safety and efficacy of structured triglycerides in parenteral nutrition in elderly patients with acute biliary tract infection.Methods 62 elderly patients with acute biliary tract infection under conservative therapy were randomly divided into structured triglycerides (ST) group and medium-chain triglycerides plus long-chain triglycerides (MCT/LCT) group.Patients underwent parenteral nutrition for 5 days.Levels of hepatic enzymes,blood triglycerides,nitrogen balance,fasting blood insulin and glucose were compared between the two groups after 5 days of parenteral nutrition.Results There were no significant differences in levels of hepatic enzymes,blood triglycerides and fasting blood glucose between ST group and MCT/LCT group.Plasma total bilirubin (T-Bill) levels were increased in the two groups,and T-Bill level dropped faster in the ST group than in the MCT/LCT group after 7 days of parenteral nutrition(P＜ 0.05).The difference in total cholesterol level dropping was significant between ST group and MCT/ LCT group (P＜0.05).The cumulative nitrogen balance for 5 days had significant difference between ST and MCT/LCT groups [(4.7-±-2.2) g vs.(2.8±0.7) g,P＜0.05].STG group versus MCT/LCT group had less fluctuation of fasting blood insulin level after 1,4 and 7 days of parenteral nutrition.Conclusions In the acute phase of biliary tract infection in elderly patients,ST-based parenteral nutrition can provide energy and help maintain nitrogen balance,with a little fluctuation of fasting blood insulin level.Short-term nutritional support may have better tolerance in the liver and has little effect on the change of hepatic enzymes.

Objective To evaluate the anti-infection effects of biodegradable implant for sustained release of cefuroxime,which can be implanted into the anterior chamber in rabbits. Methods The implants for sustained release of cefuroxime were prepared with appropriate mixtures of cefuroxime axetil(CAE),poly(lactic-glycolic) acid(PLGA) and polyvinyl pyrrolidone by solvent evaporation method.Fifty rabbits were selected and divided into experiment group(n=35) and control group(n=15).The concentrations of cefuroxime in aqueous humor 0.5,1,2,6 and 24 h after subconjunctival injection of 125 mg cefuroxime were measured in control group,and those in aqueous humor and plasma 1,2,3,5,7,14 and 28 d after implantation into anterior chamber were detected in experiment group.Besides,for experiment group,the intraocular pressure before and after the implantation were obtained;the inflammation of anterior chamber was routinely observed by slit lamp;and cornea tissues were harvested for scanning electron microscopy and light microscopy. ResultsThe concentration of cefuroxime in aqueous humor in control group reached the highest at 0.5 h after injection of cefuroxime(47 736.18 ng/mL),while that was extremely low 24 h later(10.92 ng/mL).The concentrations of cefuroxime in aqueous humor were higher than 500 ng/mL within 7 d after implantation,and that was very low at d28(59.20?39.05 ng/mL).And the plasma concentrations of cefuroxime had been at lower levels ever since the implantation(

Objective To evaluate the efficacy of naloxone used in the postoperation of cerebral tumor.Methods Eighty patients were randomly assigned to receive (treated group:40 patients) or not re- ceive (control group:40 patients) naloxone.Both the two groups accepted the conventional therapy.Re- sults After operation,the content of?-EP,ET decreased continuously but the one of the treated groups was more obviously than that of the control groups (P

In this paper, an analysis was made on the varieties and standards of labiatae medicinal plants used in Tibetan medicine. The results showed 71 species of labiatae plants in 21 genera (including varieties) recorded in relevant literatures, involving 44 varieties of medicinal materials. Specifically, seven species (9.9%) were intersected with traditional Chinese medicines (TCM), 19 varieties (43%) were recorded in Chinese medicinal material standards at all levels, and 27 species (38%) were source plants. In Tibetan medicine standards and literatures, there are great differences between Tibetan names and translated Chinese names and among varieties of source plants. Apart from a few of varieties intersected with traditional Chinese medicines had complete standards and regulations in Chinese Pharmacopoeia, most of species only had characters, microscopic, physical and chemical identifications in Standards Issued by Ministry of Health-Tibetan Medicine, Tibetan Medicine Standard and local standards. Therefore, the Tibetan medicinal material variety-source specification and quality standard system shall be promoted on the basis of literatures research, investigations for resources and current applications and modern pharmaceutical studies.

ObjectiveTo realize the relevance between hypertension and serum uric acid (SUA) in residents in Baise City.MethodsTwenty one thousand,five hundred and eighty eight Baise residents were examined.The body weight,height,waist circumference,hip circumference,blood pressure(BP) were recorded and blood lipidlevels,blood glucoseand serum uric acid (SUA) were tested.The relevance between hypertension and hyperuricemia (HUA) was analyzed by multi-factor variance analysis,x2 test,t test,linear regression and Logistic regression analysis.ResultsHypertension prevalence rate was 31.5％,the frequency of HUA was 12.0％,and 5.8％ residents had both.For patients with both hypertension and HUA,when compared to those with normal serum uric level,their mean diastolic blood pressure(DBP) was(84±10),(72±6) mm Hg res-pectively,there mean systolic blood pressure (SBP) was(151±12),(127±6) mm Hg respectively,and pulse pressure (PP) was (50±12),(37±8) mm Hg respectively.The average BMI of those two groups was (23.9±2.6),(21.7±2.4) kg/m2 respectively.The average TC level was (6.0±1.3),(5.2±1.1)mmol/L respectively,the average TG level was(2.3±2.2),(1.5±0.7) mmol/L respectively,and the average LDL-C level was(3.4±1.3),(3.0±1.1) mmol/L respectively.All these parameters were higher than those people without hypertension or HUA(P＜0.01).However,the situation of HDL-C[ (1.2±0.4),(1.5±0.5)mmol/L] was the opposite (P＜0.01).Regression analysis had shown that age,BMI,waist-hip ratio,SUA,blood glucose,TC,TG,HDL-C and LDL-C were independent risk factors for hypertension,while people with HUA was 3.1 times more when compared to those without HUA.The prevalence rate of HUA in people with hypertension was 2.6 times higher than that of the control group.ConclusionHypertension and HUA are two public health problems that prevalent in the residents in Baise City.Obesity,high blood glucose level and hyperlipidemia are thebasis for the development of hypertension and HUA.Hypertension can be the cause of HUA and verse versa.They may have mutual interactions.The adverse effect of HUA on-cardiovascular system should be taken into consideration clinically.

Objective To study prospectively the likelihood and the affecting factors of endometrial cell dissemination into the peritoneal cavity during hysteroseopie procedures.Methods A total of 121 patients with benign endometrial pathology underwent hysteroscopy combined with laparoseopy.All the patients had pelvic washings performed just before and after the procedure of hysteroscopy.We collected the peritoneal washings and analyzed the peritoneal cytology changes in both groups pre-and post-hysteroscopy, as well as the dissemination rate related to the time of hysteroscopy,the intrauterine distention pressure,the volume of distention media,and the feature of endometrial conditions.Results The ratio of positive endometrial cells in the peritoneal washings of post-hysteroscopy group was 51.2%(62/121),which was significantly higher than pre-hysteroscopy group,38.0%(46/121)(P0.05).Conclusions Hysteroseopic procedures may have a risk of disseminating the endometrial cells into peritoneal cavity.Under a certain uterine distention pressure,the rate of dissemination is correlated with hysteroscopie duration.

Class Ⅱa bacteriocins can be considered as the major subgroup of bacteriocins from lactic acid bacteria, not only because of their large number, but also because of their activities and potential applications. They have first attracted particular attention as listericidal compounds and are now believed to be the next in line if more bacteriocins are to be approved in the future. The present review attempts to provide an insight into general knowledge available for class Ⅱa bacteriocins and discuss common features and recent findings concerning these substances.
