射精管异位开口于苗勒管囊肿

报告２例射精管异位开口于苗勒管囊肿。均以血精、血尿就诊，通过经皮输精管穿刺造影及染色尿道镜检查确诊。经抗炎及窥视下纵行剪开苗勒管囊肿前壁。１例治愈，１例好转。对本病的病因、临床表现、诊断、治疗及预后进行了讨论。     

两种不同抗体双弹头标记物导向治疗肝癌的比较

在动物实验的基础上，比较了抗ＡＦＰ单克隆抗体（ｍＡｂ）和抗ＡＦＰ多克隆抗体（ｐＡｂ）两种不同抗体双弹头标记物在肝癌患者体内的生物代谢情况。结果显示，两种抗体标记物的血浆清除半衰期均在２４ｈ左右，ｍＡｂ标记物的清除较ｐＡｂ标记物略慢。尿清除的半衰期，ｍＡｂ标记物约为１２０ｈ，而ｐＡｂ标记物则约为１８ｈ，表明二者的体内生物代谢不同，疗效可能不一。     

Omega-3 fatty acid treatment fails to alter alpha 1-adrenergic receptor mediated phosphoinositide turnover in streptozotocin-induced diabetic rats

1. The effect of omega-3 fatty acid supplementation on alpha 1-adrenergic receptor-mediated phosphoinositide turnover in the hearts of 6-week streptozotocin diabetic rats was studied. 2. The diabetic state was characterized by decreased body weight gain, hypoinsulinemia and hyperglycemia. Omega-3 fatty acid treatment did not have any significant effects on the above parameters. 3. Plasma triglyceride and cholesterol levels were significantly higher in diabetic rats compared with controls. 4. Omega-3 fatty acid treatment reduced the plasma triglyceride levels in the diabetic rats, whereas plasma cholesterol levels remained unaffected. 5. Norepinephrine (10 and 100 microM) stimulated inositol monophosphate (IP1) formation was significantly decreased in the diabetic rat heart compared with controls. Omega-3 fatty acid treatment had no significant effect on the norepinephrine-mediated IP1 formation in these rats. 6. Inositol bisphosphate (IP2) formation in response to 100 microM of norepinephrine was significantly lower in the diabetic rat heart; which was also not affected by omega-3 fatty acid treatment.     

大鼠头颅瞬间侧向旋转后脑干水肿的形成及其超微形态学基础

带蚓状肌的游离足趾再造拇、手指

自１９７２年以来，在游离足趾再造拇、手指手术中，应用足趾蚓状肌与缺损拇、手指蚓状肌残端或关节囊进行缝合的方法共完成手术３００例，由于再造拇、手指的蚓状肌得到修复，既改善了其指间关节屈曲畸形，又防止了掌指关节的过伸。术后随访１－２２年，再造拇、手指的外形及功能均满意。     

新药甲磺酸帕珠沙星的手性拆分

目的：建立新药甲磺酸帕珠沙星手性拆分的方法。方法：运用AD手性柱法和流动相添加剂法，考察了不同条件下对分离的影响。结果：运用这两种方法，甲磺酸帕珠沙星都可以达到基线分离，相同条件下，柱温越低，拆分因子越大。结论：在分离甲磺酸帕珠沙星时，流动相添加剂法要优于手性柱法。     

毛喉萜对人肝癌细胞增殖影响的实验研究

目的　探讨毛喉萜 (Forskolin)的抗肝癌作用。方法　采用克隆形成、MTT比色法观察毛喉萜对SMMC 772 1细胞的作用 ,并利用免疫细胞化学方法检测其对rasp2 1、p5 3蛋白表达的影响。结果　毛喉萜可明显抑制SMMC 772 1细胞的增殖 ,其抑制率与剂量呈正相关 (P <0 .0 1 ) ,经毛喉萜处理后 ,rasp2 1、p5 3蛋白表达均有明显下降。结论　毛喉萜能明显抑制肝癌SMMC 772 1细胞增殖 ,其作用可能与降低rasp2 1、p5 3蛋白表达有关。
