新时期戏剧艺术探索的成就与困顿

八十年代初中期 ,中国戏剧积极拓展我国传统戏剧的时空观、写意性特征 ,大胆借鉴西方现代戏剧的荒诞化、意象性技巧 ,出现了探索创新、多元发展的崭新局面。其中对“三一律、一堵墙”戏剧观的突破 ,运用意识形象外显人物的内心世界 ,嫁接多种艺术手段将现实时空转化为艺术时空 ,是新时期戏剧艺术探索最突出的三项成就。而过分强调形式技巧 ,脱离观众欣赏习惯 ,致使演出市场萎缩 ,观众锐减 ,无疑是新时期戏剧艺术探索中面临的最大困顿。     

小儿先天性髋关节脱位近年来应用术式的演变及其评估

本文介绍本院近４年来小儿先天性髋脱位治疗应用术式的演变。由２０多年来一直喜欢用骨盆截骨术演变为近１年来用得最多的是造盖术。近４年共手术４６３例，５６５髋。实践证明：比起骨盆截骨术，造盖术显得更简便，侵袭小，不需二次手术拔除内固定针。因在我国大龄髋脱位偏多，造盖术更适合我国国情。经过一些改进，可以克服造盖折断和吸收问题。     

Inter- and intra-individual variability of non-invasive tear break-up time in Hong Kong Chinese

Non-invasive tear break-up time (NITBUT) has been proposed as a measure of tear film integrity which is superior to the more commonly used tear break-up time (TBUT), since it does not alter the volume or the physicochemical properties of the tear layer by the addition of fluorescein. We measured NITBUT by measuring the time taken for distortions or discontinuities to appear in the reflected image of a grid pattern which covered about 80 per cent of the corneal surface. NITBUT measures were made 100 times on seven Hong Kong Chinese subjects with up to 20 consecutive measures being made on a single day. We also measured NITBUT on one occasion on an unselected population of 52 Hong Kong Chinese subjects. NITBUT shows a skewed distribution in all subjects, with many shorter values and some extremely long values. There are statistically significant variations in NITBUT from day to day, and from subject to subject. The group of 52 subjects also had a skewed NITBUT distribution with many short values and some very long values. The arithmetic mean does not adequately represent NITBUT data, either for individual subjects or for this group of subjects. As many as five to eight measures may be necessary to gain a stable estimate of the NITBUT and stability of the measure is improved if extreme values are omitted. We recommend the use of nonparametric statistics to compare NITBUT values from day to day in or between subjects.     

低位无肛术术中完整保留瘘口组织的必要性和可行性

目的探讨低位肛门直肠畸形术术中保留瘘口组织的必要性和可行性。方法对67例无肛前庭及会阴瘘患儿的临床资料进行回顾性分析。其中女童无肛前庭瘘59例,男童无肛会阴瘘8例。年龄3个月~16岁,平均10个月。患儿多以排便困难或肛门位置异常就诊。4例无肛前庭瘘患儿曾在婴儿期行瘘口后切术。患儿均采用完整保留瘘口的前矢状入路肛门成形术治疗。结果患儿术后3及6个月常规来院复诊,最长随访8年。65例(97.0%)患儿会阴部矢状切口一期愈合,会阴及肛门外观良好;另2例(男、女各1例)术中直肠破损患儿,自修补处穿孔导致会阴部矢状切口感染(占直肠破损修补术的40%),最终形成直肠会阴瘘,但肛门外观良好。67例均采用肛门功能临床评分标准评估患儿排便功能,64例(95.5%)患儿排便功能良好,总评分为5~6分;另3例(男1例,女2例)顽固便秘,需开塞露协助排便。结论低位无肛术中完整保留瘘口组织非常必要。     

外伤性肝破裂的救治

目的 分析创伤性肝破裂外科多种干预治疗的效果。方法 总结分析1982-2002年我院收治创伤性肝破裂76例的救治方法和病死率。其中Ⅲ级以上的严重肝破裂46例(60．53％)。手术治疗56例，手术方式包括单纯修补、清创性肝切除、规则性肝切除、肝周填塞止血；非手术治疗20例。结果 手术组：治愈44例，术后并发症17例均经保守治疗治愈，死亡12例，其中术中死亡2例；非手术组：治愈12例，好转6例，2例失访。全组治愈64例，死亡12例，病死率15．8％。结论 Ⅰ-Ⅱ级单纯性外伤性肝破裂可保守治疗；手术是治疗创伤性肝破裂的主要措施，正确的手术方式，积极处理合并伤，重视综合治疗可提高救治成功率。     

Postgraduate qualifications of British doctors

Among British-qualified doctors of 1974 and 1977, about 80% held postgraduate qualifications of some kind. The commonest qualifications were DRCOG, MRCP and MRCOG. There were considerable differences between medical schools in the numbers of qualifiers taking various examinations. Apart from the MRC Psych, DRCOG and Family Planning Certificate, qualifications were more commonly held by men than women. Tables show the type of work being done 9-13 years after leaving medical school by holders of various postgraduate qualifications; e.g. 60% of MRCP holders were working in medicine or a medical specialty and 84% of FRCS holders in general surgery or a surgical specialty. Discussion deals with the plurality, specificity, variability, perceived necessity, sufficiency, international utility and career significance of British postgraduate qualifications.     

保留齿状线加皮桥重建闭合切口治疗环状混合痔32例疗效观察

目的探讨保留齿状线加皮桥重建闭合切口治疗环状混合痔的可行性及疗效。方法治疗组选用保留齿状线加皮桥重建闭合切口32例，与对照组采用传统外剥内扎治疗34例在术后疼痛、水肿、出血、痔残留等并发症及住院时间、愈合时间等方面进行比较。结果治疗组在术后疼痛、水肿、出血、痔残留等及住院时间、愈合时间等方面均优于对照组。结论保留齿状线加皮桥重建闭合切口治疗环状混合痔安全、有效、可行。
