Value of intravenous urography before shockwave lithotripsy in the treatment of the middle and lower ureteral calculi / 中国基层医药

Objective To study the impact of preprocedure intravenous urography(IVU)on the outcome of shock wave Iithotripsy(SWL)for the middle and lower ureteral stones.Methods 112 patients with solitary radiopaque the middle and lower ureterat stones on plain radiographs and no severe hydronephrosis on ultrasonographic examination were divided randomly to two treatment groups.IVU group(n=56)had IVU before the start of SwL,whereas patients in the control group(n=56)underwent SWL without IVU.Postoperative success,stone-free rates and complications were evaluated in both groups.Results Eleven patients in the IVU group were excluded from the study.The SUCCESS rate[91.1%(41/45)in IVP group VS 94.6%(53/56)in control group],stone-free rate[88.9%(40/45)vs 89.3%(50/56)],and complication rate[22.2%(10/45)vs 21.4%(12/56)]were similar in two groups(P＞0.05).ConclusionIt is not necessary to obtain an IVU for patients who have solitary radiopaque the middle and lower calculi on plain radiographs with no severe hydronephrosis on ultrasonographic examination before scheduling them for SWL,thus minimizing the cost,avoiding exposure to contrast medium,and reducing radiation exposure.

Assessment system of research program upgraded / 医学研究生学报

The authority of hospital administration in charge of the science and technology development will adopt the standard of national evaluation system and implimentation approach into practical regulation.The research projects will be judged by new items including the research objective,demonstration medality,graunds of argument,classification systems,etc. The goal of the new guidelines carried will assure the open and fair policy being practised in examining the adequacy of the research program. The scceessful implimentation of the new rule will encourage the development of highly qualified results achieved in research schemes,and bring about greater social and economic benefits from extensive research work.

Comparison of neuromuscular blockade in slow and fast muscles following administration of pancuronium or atracurium in rats / 中华麻醉学杂志

0.05) in ED,ED, recovery index (time between 25% and 75% recovery),the maximal depression and the maximal recovery of twitch response between slow and fast muscles following Pan or Ate. It is indicated that the dose-response and time-response relationships of Pan or Atc may be similar in slow muscles to those in fast muscles.
