老年急重症胆管炎临床分析

目的：探讨重症胆管(ACST)患者的临床特点及死亡原因。方法：分析我院近十五年来收治46例ACST的治疗情况。结果：手术41例．非手术5例，死亡9例，其中手术治疗死亡6例。结论：老年ACST患者，伴发病多，死亡率高，及时就诊，早期应用大量激素，选择适宜手术方法是降低死亡率的关键。     

不稳定型下颈椎损伤的手术治疗(附56例分析)

目的分析手术治疗下颈椎不稳定性损伤的适应证、手术方法及疗效。方法2001年1月～2003年1月,手术治疗下颈椎不稳定性损伤共56例。参照Aebi及White等人的手术适应证,以前路手术为主;对于难复性颈椎脱位或不伴椎间盘损伤者,行后路施术或前后联合入路手术;稳定性评分大于8分的前后柱损伤者,行前后联合入路手术。以Frankel评分系统评价神经功能恢复情况,以损伤节段Cobb角及水平移位来评价复位情况,采用Bohlman的X线片标准判定植骨融合情况。结果Frankel评分术前平均为2.3分,术后3.1分;按Bohlman标准3个月时植骨融合率为80%,6个月时为100%。术前Cobb角平均为8°,术后为1.5°,水平移位由术前的平均3.5mm减小到0.5mm。结论手术治疗下颈椎不稳定性损伤具有改善神经功能、恢复颈椎序列、恢复椎间高度及生理曲度、可早日下地活动等优点,手术病例及方法的选择应根据患者是否有致压因素及颈椎稳定性等综合考虑。     

动脉瘤术后血管痉挛的综合治疗(附284例报告)

目的总结动脉瘤手术后血管痉挛及延迟性缺血性神经功能障碍(DIND)的防治经验。方法回顾性分析284例接受颅内动脉瘤夹闭术病人的临床资料,对颅多普勒超声(TCD)的结果与DIND的发生情况进行统计分析。结果137例病人手术后发生血管痉挛,79例发生DIND。TCD所示血流速度与DIND的发生有密切的相关关系。经治疗,62例DIND病人(78.5%)症状消失。病死率2.5%。结论血管痉挛是导致DIND的主要因素,个体化的综合治疗能明显提高疗效。     

The Post Therapy Breast

Both systemic and local therapy, for conditions of the breast and unrelated to it, may produce manuno-graphic changes. Some of these are characteristic, such as the pattern of scarring seen in reduction mammo-plasty. In many other instances, however, the changes produced overlap features commonly seen in malignancy. A knowledge of the timing, natural history and spectrum of these changes will aid mammographic interpretation.     

肺心病血液光量子治疗前后血液流变性质变化及机制探讨

１５例肺心病血液高粘滞患者自体血２５０ｍｌ用ＸＺＹ－Ⅰ型量子血液治疗机进行紫外线照射和充以纯氧后再输入，每周一次，最多连续做三次（平均１．８６±０．７１次）后，作者发现血液全血高切、低切粘度，全血高切、低切还原粘度，血浆比粘度，血浆纤维否白原含量，红细胞聚集指数，红细胞电泳率等有显著性改变，单纯常规治疗组１５例患者血液流变无此变化，分析认为，这些变化可能与红细胞聚集性降低、纤维蛋白源溶解度提高及血氧饱和度增加有关。     

Referral pattern of patients with oral mucosal lesions in The Netherlands

The referral pattern of 140 Dutch patients with oral mucosal lesions, who had been referred to a Department of Oral & Maxillofacial Surgery and Oral Pathology, shows that patients with oral mucosal lesions consult the dentist as often as the family doctor as the first source of help or information. Furthermore, family doctors were much more used to refer patients with oral mucosal disease to medical specialists rather than to the dentist or the oral and maxillofacial surgeon.     

Long-term follow-up by video of cervical dystonia treated with botulinum toxin

We have analysed video recordings of 21 patients with cervical dystonia treated with botulinum toxin. Fourteen patients have a record both of their response shortly after injections were commenced and between four years five months and six years seven months later. Our analysis shows that the long term outcome is often better than the initial response. We suggest that chronic treatment with botulinum toxin allows different muscles to those initially injected to be identified as contributors to the dystonia. Subsequent injection of these muscles leads to further improvement. It implies that cervical dystonia is a more widespread disorder of motor control, rather than simply limited to a few muscles.     

胰腺分裂与慢性胰腺炎的病因学关系及发病机制

目的:探讨胰腺分裂(PD)在慢性胰腺炎病因学中的作用及其发病机制。方法:将32只犬随机分为4组(每组8只)。Ⅰ组:部分结扎背-腹胰管间的交通支。Ⅱa组:切断并结扎交通支。Ⅱb组:在背胰管注入小乳头前2mm处将其切断并结扎断端。Ⅲ组:假手术对照组,除不结扎交通支外,其余操作同上。于手术前检测各组犬血清磷脂酶(PLA2)和淀粉酶(Ams)活性及背、腹胰管基础压并在胰泌素激发后15、30、45、60和90分钟各测压一次。于术后180天再行胰胆管测压和造影并观察背、腹胰和十二指肠乳头的病理改变。结果:⑴Ⅰ、Ⅱa组和Ⅱb组术后5-80天血清PLA2和Ams活性显著升高。⑵处死时Ⅰ、Ⅱa组腹胰管和Ⅱb组背、腹胰管压力在激发后30-60分钟显著高于注药前(P<0.01);在60分钟后,前两组压力恢复到术前水平(P>0.05),而Ⅱb组仍较高(P<0.05),该组压力在90分钟后恢复正常。⑶光镜:Ⅱb组犬背、腹胰小叶间或/和胰管周围显著纤维组织增生,腺细胞结构破坏和炎细胞浸润。Ⅰ和Ⅱa组腹胰见轻度上述改变。⑷电镜:Ⅰ、Ⅱa组腹胰和Ⅱb组背、腹胰腺细胞粗面内质网脱颗粒、融合和扩张。酶原颗粒减少,线粒体肿张。Ⅰ和Ⅱa组背胰及Ⅲ组背、腹胰未见异常。结论:PD是慢性胰腺炎的病因学因素之一,其引发胰腺炎的机制是在胰液分泌的高峰期副乳头功能性梗阻。     

我对子午流注阴阳盛衰转换的认识

阐述了时相与阴阳的关系，阴阳昼夜的盛衰转换与经脉循行、气血流注密切相关；对传统流注说和任督为主的阴阳循环说进行了分析，认为子午流注阴阳盛衰转换在妇科学中有重要意义，子午流注所指出的4个较重要的时期与月经周期中的4期(行经期、经后期、经间排卵期、经前期)相关。重视研究日相阴阳太极钟的变化，将能更加深入地认识月经周期中阴阳消长转化的规律变化，从而推动中医妇科学向前发展。     

小包装全氟丙烷气体动力学实验研究

为检验塑料小包装全氟丙烷气体（C3F8）在不同包装和储存方法时浓度变化，将装有5～7mlC3F8的聚氯乙烯小袋，根据不同储藏温度和外包装方法随机分成四组：（1）22℃聚乙烯外包装，（2）36℃聚乙烯外包装，（3）22℃铝箔真空外包装，（4）-29℃聚乙烯外包装；每一组C3F8小袋气体存放一定时间后，应用气相色谱分析方法进行浓度测量。结果：第3组C3F8浓度最高和稳定，第2组浓度随放置时间降低最明显，第4组是临床应用气体的储藏和包装方法，其30天样本浓度和第3组相等，但放置一年时浓度降低。结果显示：塑料小包装C3F8予以铝箔真空外包装是一种可行的方法，利于C3F8运输和普及；聚乙烯外包装的C3F8，应放在-29℃保存，时间不超过一年。
