D1期前列腺癌的诊断

１９９０年１２月至１９９３年１２月，我们对临床Ａ－Ｃ期２７例病人进行盆腔淋巴结活检术，检出１２例Ｄ１期病人。临床Ａ期有５０％，Ｂ期有３７％，Ｃ期有７１％的病人发现盆腔淋巴结癌转移，其癌细胞的恶性程度也与淋巴结癌转移有关。近年，经腹腔镜盆腔淋巴结活检已成为诊断Ｄ１期前列腺癌的新方法。     

大鼠气管上皮细胞体内—体外转化模型的研究

本研究建立了大鼠气管上皮细胞体内－体外转化模型，大鼠气管内滴注苯并芘，三天后处死大鼠，消化气管上皮细胞，接种于无血清完全培养基。细胞形成集落后，换为选择培养基继续培养五周，统计转化率。结果显示，２５ｍｇ／ｋｇ和５０ｍｇ／ｋｇ的苯并芘可诱导大鼠气管上皮细胞转化及微核增加，用同样方法研究了煤焦沥青提取物，结果表明，剂量为８ｍｇ／ｋｇ和２５ｍｇ／ｋｇ的煤焦沥青提取物能明显诱导大鼠气管上皮细胞转化。     

血脂调节剂的研究——Ⅰ.HMG-CoA还原酶抑制剂M-8614A及MH-2688B产生菌的筛选

利用酶联免疫吸附测定法,酶标β-羟基β-甲基-戊二酸单酰铺酶A(HMG-CoA)还原酶抑制剂Compactin抗体,定向筛选血脂调节剂。从青霉M-8614菌株发酵液中分离到M-8614A。该物质理化性质及波谱解释表明与Mevastatin为同一物质。 M-8614菌株用亚硝酸盐等诱变剂处理,从诱变株MH-2688发酵液中分离到MH-2688B。该物质理化性质及波谱解释表明与Lovastatin为同一物质。     

颌骨造釉细胞瘤64例临床分析

本文对我院１９５４－１９９０年收治的６４例颌骨造釉细胞瘤进行了回顾性分析，未发现１例恶性。特别是我们在长期工作实践中发现肿瘤与周围正常骨质有较明显的分界。遂于１９６３年开始试行颌骨内种瘤出术，至１９９０年６月已经成功地施了１２例，１例因手术时肿物巨大而且合并感染于术后１０年复发外，其余１１例术后随访年６个月－２７年，中位１２年１０个月均无复发。发种手术损伤小，方法简单，无损美容，预后性，特别是对颌     

桑寄生、四川寄生、红花寄生中槲皮素的含量测定

采用双波长薄层扫描法测定桑寄生、四川寄生、红花寄生中槲皮素的含量。方法简便、准确、无杂质干扰。槲皮素含量分别为0.027%、0.12%、0.31%,回收率分别为97.8%、98.6%,98.0%。     

经结膜下穹隆至上颌窦插管术治疗泪道阻塞的临床研究

采用经结膜囊下穹隆至上颌窦插管的术式引流泪液，治疗泪道阻塞引起的溢泪症，获得较为满意的效果。手术的主要步骤是：局麻后于结膜囊下穹隆内1／3区作一4mm长的结膜切口，自筋膜下分离至眶线下5mm。从切口伸入上颌窦骨钻钻通上颌窦顶壁，插入长短适度的义管，并向管内注入生理盐水，证实有液体流入鼻咽部后，固定义管。术后定期冲洗，无需拆线，应用这种术式治疗泪道阻塞引起的溢泪症218眼，其中溢泪完全消失151眼占82．1％，溢泪减轻的27眼占14．6％，总效率96．7％。     

胰腺肿瘤的B型超声诊断

本文将资料完整的并经手术及病理证实的27例胰腺肿瘤初步小结。详细描述各例肿瘤的临床们诊与诊断、B型超声和手术情况，并重点讨论：临床们诊和B型超声未能检出的肿瘤，检出肿瘤大小较手术所见尺寸的要，10mm～40mm以及未见肿瘤浸润的原因。     

抗淋球菌IgA蛋白酶单克隆抗体特性的初步研究

本文对以重组淋球菌ＩｇＡ蛋白酶为抗原制备的７株特异性ＭｃＡｂ的特性进行了初步研究。结果有５株（１Ｃ８、１Ｅ５、１Ｆ１１、１Ｇ３和２Ｅ６）能中和淋球菌ＩｇＡ蛋白酶活性。经相加试验初步证明，其中１Ｆ１１、２Ｇ３与其它３株ＭｃＡｂ的作用位点不同。因此，淋球菌ＩｇＡ蛋白酶至少存在３个中和表位。     

Effects of Ethanol in an Experimental Model of Combined Traumatic Brain Injury and Hemorrhagic Shock

Objectives: Given that clinical and laboratory studies suggest that ethanol and hemorrhagic shock (HS) potentiate traumatic brain injury (TBI), the authors studied the effects of ethanol in a model of combined TBI and HS.
Methods: A controlled porcine model of combined TBI and HS was evaluated for the effect of ethanol on survival time, hemodynamic function, and cerebral tissue perfusion. Anesthetized swine (17–24 kg) were instrumented, splenectomized, and subjected to fluid percussion TBI with concurrent 25-mL/kg graded hemorrhage over 30 minutes. Two groups were studied: control ( n = 11) and ethanol ( n = 11). Ethanol, 3.5 g/kg intragastric, was given 100 minutes prior to TBI/HS. Systemic and cerebral physiologic and metabolic parameters were monitored for 2 hours without resuscitation. Regional cerebral blood flow (rCBF) and renal blood flow were measured with dye-labeled microspheres. Data were analyzed with 2-sample t-test and repeated-measures ANOVA.
Results: Ethanol levels at the time of injury were 162 ± 68 mg/dL. Average TBI was 2.65 ± 0.35 atm. Survival time was significantly shorter in the ethanol group (60 ± 27 min vs 94 ± 28 min, p = 0.011). The ethanol group had significantly lower mean arterial pressure, cerebral perfusion pressure, and cerebral venous
O₂ saturation in the postinjury period. Cerebral O₂ extraction ratios and cerebral venous lactate levels were significantly higher in the ethanol group. A trend toward lower postinjury rCBF in all brain regions was observed in the ethanol group.
Conclusion: In this TBI/HS model, ethanol administration decreased survival time, impaired the hemodynamic response, and worsened measures of cerebral tissue perfusion.
