中药鸦胆子化学成分的研究 (一)鸦胆子油

据本草纲目拾遗,鸦胆子一名苦参子,可治痔、治痢、治泻,其油治脱癌;裴鉴及周太炎二氏报告,鸦胆子系苦木科植物 Brucea javanica(L)Merr.的果实;吴其浚植物名实图考内载:一种鸦蛋子生云南与鸦胆子不同能治痔云。考我国于1751年何梦瑶氏曾用鸦胆子作治痢,1765年赵学敏氏在本草纲目拾遗上亦谓可治痢,张锡纯、李克惠二氏云可治慢性痢及久痢。近二十年来我国学者关于鸦胆子研究不论在化学、生理、药理方面以及临床试验均有报告,认为有截疟及治痢之效,但有中毒现象。作者由其仁中分出一种苦味甙,据浙江医学院陈志康氏研究谓有治肺吸血虫病之效。其油据于光元及李宝实二氏报告可治疣及乳头瘤。全慈光氏报告可治阿米巴痢、疟疾及杀虫。Power 及 Lees 报告,全果实含有油脂20%;其成分为油酸、亚麻仁油酸、软脂酸及硬脂酸,并含一种烟化物名 Pentatriacotane-C,熔点     

Surgical hip dislocation in symptomatic cam femoroacetabular impingement: what matters in early good results?

In order to assess outcome and possible predictors of early good results, a prospective study on 22 patients who were treated with save surgical hip dislocation for symptomatic isolated cam-type femoroacetabular impingement (FAI) was performed. After a follow-up of 6 and 12 months, standard clinical and radiographic parameters were recorded. A statistically significant improvement of the clinical status according to the Harris hip score could be assessed at six months (p-value = 0.003) and 12 months (p-value = 0.001) post-surgery. By comparing standard clinical and radiographic preoperative parameters with various follow-up outcomes, we revealed no specific parameter with predictive value. These findings are important for centers that have just started to use this surgical technique and are still identifying their learning curve.     

Validation of the treatment identification strategy of the HEDIS addiction quality measures: concordance with medical record review

Background  

Strategies to accurately identify the occurrence of specific health care events in administrative data is central to many quality improvement and research efforts. Many health care quality measures have treatment identification strategies based on diagnosis and procedure codes - an approach that is inexpensive and feasible but usually of unknown validity. In this study, we examined if the diagnosis/procedure code combinations used in the 2006 HEDIS Initiation and Engagement quality measures to identify instances of addiction treatment have high concordance with documentation of addiction treatment in clinical progress notes.     

SUBACUTE HEPATIC FAILURE-A CLINICAL PROFILE

A combined experience of 37 cases of subacute hepatic failure encountered in five major gastroenterology centres over a period of ten years is discussed. Majority (65%) were males with average age of 38 years. Maximum (54%) were in 5th decade. Jaundice (100%), abdominal distention (38.7%), swelling feet (64%), fever (54%), abdominal pain (54%), exhaustion (78.3%) were the major presenting features. Jaundice and ascites were present in all cases. Pedal oedema (78.3%), hepatomegaly (54%), splenomegaly (32.4%) and encephalopathy (27%) were the other important clinical features. Hypoalbuminemia and prolonged prothrombin time were significant laboratory findings in addition to hyperbilirubinemia and elevated ALT and AST. Hbs Ag was detected in 46%. Major complications encountered were renal failure (48.7%), spontaneous bacterial peritonitis (43.2%), other infections (43.2%), encephalopathy (43.2%) and upper gastrointestinal bleed (22%). 54% died during stay in hospital. To conclude subacute hepatic failure is potentially fatal condition.KEY WORDS: Subacute hepatic failure, HBsAg, Jaundice
