氧自由基致痛、痛敏及其与阿斯匹林、吲哚美辛镇痛的关系

采用光照核黄素产生氧自由基，观察后者在外周和脊髓水平对疼痛的影响。发现在外周，小鼠足跖部皮下注射ＬＲＦ０．０６，０．６７ｍｍｏｌ．ｍｏｕｓｅ＾－１有致痛作用；脊髓水平，小鼠鞘内注射ＬＲＦ０．１０６－０．６６５ｎｍｏｌ．ｍｏｕｓｅ＾－１有致痛敏作用；进一步研究发现ＯＦＲ的脊髓痛敏与Ｃａ＾２＋有密切关系，用维拉帕米，尼莫地平，ＥＧＴＡ可拮抗ＯＦＲ的痛敏作用。     

生殖道解脲支原体和沙眼衣原体感染与女性不孕的相关性研究

目的探讨生殖道解脲支原体（UU）和沙眼衣原体（CT）与女性不孕症的关系。方法对305例不孕症患者（观察组）和130例正常女性（对照组）,应用荧光定量PCR技术检测生殖道分泌物中的UU和CT,观察两组的差异。结果观察组UU、CT、UU和CT双重感染率分别为59．3％、41．0％和17．0％,均明显高于对照组（x2=89．82、44．86、19．11,均P〈0．05）;原发性不孕组UU、CT感染率与继发性不孕组比较,差异均无统计学意义（均P〉0．05）。结论UU和CT的感染与女性不孕症有一定的相关性。     

实时三维超声在膀胱癌虚拟立体模型及体积测量中的应用

目的探讨实时三维超声在膀胱癌虚拟立体模型及体积测量中的应用价值。方法对经膀胱镜活检病理确诊的29例膀胱癌患者,进行实时三维超声扫查,然后应用虚拟组织计算机辅助分析（VOCAL）技术对癌体虚拟立体模型及体积测量。结果实时三维超声不仅在膀胱癌虚拟立体模型明显优于三维图像,并且癌体体积测量十分准确。结论应用实时三维超声VOCAL技术,在膀胱癌虚拟立体模型,能够客观准确地反映癌体空间形态,并且对癌体积测量更加准确。

巨大儿的相关因素及对母婴的影响

目的探讨巨大儿的发生率、相关因素、分娩方式及其对母婴的不良影响,从而预防巨大儿的发生,减少其并发症,降低产科风险.方法对1989-2004年在我院分娩的巨大胎儿694例进行回顾性分析,择紧接巨大儿之后分娩的单胎足月(2500～3999g)孕妇作为对照组,对巨大儿的发生率及其相关因素进行比较分析.结果巨大儿发生率近年来逐步上升,发生率为7.12%,巨大儿组与对照组相比,两组孕妇身高、BMI、宫高 腹围和胎儿BPD FL有显著的差异(P＜0.01),且巨大儿组手术助产、剖宫产、母婴并发症发生率均明显增高(P＜0.01).结论重视巨大儿的预防,加强产前检查,及时诊断,选择合理的分娩方式,对于降低巨大儿发生率,减少母婴并发症有重要的意义.     

Role of cholinergic and adrenergic mechanisms in the action of ketamine and thiopental sodium on the structures of the hippocampal-reticular complex and the neocortex

Under conditions of free behaviour of rabbits with electrodes implanted into the brain structures it was found that ketamine and sodium thiopental decrease the excitability in the dorsal hippocamp, reticular formation and periaqueductal gray matter of the midbrain. Excitability of the frontal neocortex increases during general anesthesia with ketamine and decreases during thiopental narcosis. Changes in excitability of the studied cerebral structures during general anesthesia can be determined by common N-cholinoblocking and alpha-adrenomimetic properties of ketamine and thiopental at the level of the dorsal hippocamp, cholinoblocking and adrenoblocking properties at the level of the reticular formation and central gray matter. In the frontal cortex ketamine presented properties of an M-cholinomimetic and adrenomimetic agent, sodium thiopental--those of a M-cholinoblocker and beta-adrenoblocker.     

Comparison of the efficacy and tolerability of dexibuprofen and celecoxib in the treatment of osteoarthritis of the hip

CONTEXT: Osteoarthritis (OA) is often treated with nonsteroidal anti-inflammatory drugs (NSAIDs) or selective inhibitors of cyclooxygenase-2 (COX-2). OBJECTIVE: This clinical trial aimed to assess directly the relative therapeutic efficacy of the isolated active enantiomer of ibuprofen, named dexibuprofen (S(+)-ibuprofen) in a special crystal form, and the selective COX-2 inhibitor celecoxib in adults with OA of the hip. Moreover, the hypothesis that the tolerability/safety profile of dexibuprofen is comparable to celecoxib is to be tested. METHODS: The investigation was a randomized, parallel-group, double-blind, active controlled clinical trial, conducted from January 2001 to February 2002 in 4 rehabilitation centers in Austria. 148 inpatients were randomly assigned to dexibuprofen 800 mg or celecoxib 200 mg daily. The primary criterion was the improvement in the Western Ontario and' McMasters osteoarthritis index (WOMAC OA index) after 15 days of therapy. RESULTS: Evaluation of the WOMAC OA index proved that dexibuprofen 400 mg b.i.d. is not inferior to celecoxib 100 mg b.i.d. with the Mann-Whitney estimator equal to 0.5129 and the corresponding lower boundary of the 95% confidence interval equal to 0.4409. The overall incidence of adverse drug reactions was 12.16% in the dexibuprofen group and 13.51% in the celecoxib group. 8.1% of patients on dexibuprofen and 9.5% on celecoxib suffered from gastrointestinal disorders. CONCLUSION: In the presented clinical trial dexibuprofen has at least equal efficacy and a comparable safety/tolerability profile as celecoxib in adult patients suffering from osteoarthritis of the hip.
