中西医结合治疗坏死性筋膜炎

本文积累了１９８１～１９９４年近十余年的临床资料，总结了中西医结合治疗坏死性筋膜炎的临床治疗经验。指出坏死性筋膜炎是一种少见的严重的软组织感染，发展迅速，病死率高，应引起临床医生的高度警惕，做出早期诊断是非常必要的。提出了扶正祛邪的中西医结合的整体治疗方案，全身治疗与局部处理相结合。对患处要采取早期，这时的多切口引流，给＂邪＂以出路。取得良好的疗效。     

动脉分支处的红细胞流变学研究与小动脉端侧吻合

为了探讨动脉分支处及小动脉端侧吻合处的血液流动方式，采用微循环电视显微镜成像技术，活体观察大鼠肠系膜微动脉分支区域血液流动方式和红细胞流变行为，研究动脉血流方向的改变对血流方式的影响。实验中观察到，在形态各异的大鼠肠系膜微动脉分支区域血液流态为稳定层流；红细胞通过不规则变形能很好地适应血管腔不同的几何形态，以保持血液流态的稳定。结果表明，微小动脉血流方向的改变未能在分支区域导致湍流发生，小动脉端侧吻合只是人为增加了侧支循环，同样不会导致血流紊乱和增加血栓形成的危险     

The effect of individual HLA-A and -B mismatches on the generation of cytotoxic T lymphocyte precursors

In order to study the correlation between HLA mismatches and the cytotoxic T lymphocyte precursor frequency, we used a limiting dilution analysis to determine the CTLp frequencies against individual mismatched HLA-A and -B alloantigens in 21 patients waiting for a renal transplant. Altogether, thirty-three mismatched HLA-A antigens and 55 HLA-B antigens were tested. The CTLp frequencies against mismatches of HLA-B locus antigens were found to be significantly higher than those against HLA-A antigens (P less than 0.002). This may explain why matching for HLA-B antigens is more important for a good renal allograft survival than matching for HLA-A antigens.     

Effects of an anti-interleuktn-6 (IL-6) murine monoclonal antibody in a patient with acute monoblastic leukemia

Because IL-6 has been involved in the pathogenesis of acute monoblastic leukemia, we investigated thein vitro anti-proliferative effect and thein vivo anti-tumoral effect of an anti-IL-6 murine monoclonal antibody (mAb) in a patient with MSB type acute leukemia. In the current study, we clearly show the IL-6 dependence of monoblastic cell viability and proliferationin vitro in short-term cultures of malignant cells and the clinical activity of the anti-IL-6 murine mAb. The complete neutralization of IL-6in vivo was associated with a transient but complete disappearance of malignant monoblastic cells in the peripheral blood, with improvement or even normalization of several other biological parameters of disease activity, No immunization against the anti-IL-6 murine mAb was observed.     

肺移植急性排斥反应及其控制实验研究

观察了大鼠实验性肺移植术后急性排斥反应的病理改变。异系间移植术后２ｄ，移植肺内小血管及支气管周围出现单核细胞浸润。４ｄ上述细胞浸润波及肺泡壁，导致肺泡壁增厚，肺内小静脉系及毛细血管管腔变窄，血流不畅。术后６ｄ，血液循环严重障碍处，肺泡完全坏死，环抱素Ａ可使上述排斥反应得到明显抑制。     

TPA诱导的血小板聚集的研究

应用不同浓度ＴＰＡ诱发血小板聚集，观察２０名正常人血小板的聚集率。结果显示：ＴＰＡ从５ｎｇ／ｍｌ到１０ｎｇ／ｍｌ之间，随着浓度的增加，血小板聚集率逐渐增加，最佳浓度为１０ｎｇ／ｍｌ。当ＴＰＡ浓度〉１０ｍｇ／ｍｌ时，继续增加ＴＰＡ浓度，血小板聚集率将不再升高，且于２０ｍｇ／ｍｌ时出现明显的解聚现象。     

恩施土家族人眼的表面形态特征

按随机抽样原则选择湖北恩施土家族人５９８名观测了眼的表面形态。该民族大部分人两眼位置适中，虹膜褐色，眼裂水平，开度中等，无蒙古褶，双睑；多为细窄眼型或中等眼型；眼的各径男大于女，一般存在性别差异；随年龄增加，眼型由中等型向细窄型转化，根据眼外形特征和聚类分析推测，土家人眼属于南、北方民族间的过渡型。     

雌激素,胎盘生乳素,钙,磷与妊高征的关系

目的：探讨雌激素，胎盘生乳素，钙在妊高征发病中的作用及其相互关系，方法：采用放射免疫法及离心分析钙试剂，测定了４２例妊高征患者血清雌二醇，胎盘生乳素，钙，磷及尿钙，磷的含量，３４例同期门诊正常孕妇作为对照组，结果：轻度妊高征患者血清雌二醇明显增加（Ｐ〈０．０５）。重度妊高征患者血清胎盘生乳素显著减少（Ｐ〈０．０５），轻，中，重度妊高征患者血钙，尿钙含量显著降低（Ｐ〈０．０５，Ｐ〈０．０１，Ｐ〈０．     

消炎痛及乙胺嗪对动物急性缺氧性肺、脑血管反应的影响

研究消炎痛及乙胺嗪对家兔肺、脑血管和大鼠脑微动脉缺氧反应的影响。发现吸入10％氧使家兔肺血管阻力(PVR)增加,脑血管阻力(CVR)降低,大鼠脑微动脉扩张。用消炎痛明显增强家兔缺氧性肺、脑血管反应。△PVR％由用药前26.6±16.7％增至44.2±7.7％;△CVR％则由一12.9±4.5％减至-30.7±4.7％;大鼠微动脉直径增大率(△D％)由用药前28.2±2.0％增至41.3±5.8％;用乙胺嗪则使缺氧时△PVR％由 84.6±18.1％降至 23.8±8.5％;△CVR％由-16.7±4.5％变为 6.9±2.8％;△D％由 29.7±5.8％减至 25.6±5.0％。结果表明前列腺素在缺氧性肺血管收缩反应及脑血管扩张反应中起调节作用,而白三烯则在缺氧性肺血管收缩反应中起介导作用。
