305例尿石成份分析及预防对策

目的研究一种快速、简便的方法对泌尿系结石进行分析,并探讨其防治方法。方法用化学常量法对305例患者的尿石标本进行化学成份测定,并结合临床资料进行分析。结果发现结石发病男性多于女性(比例为3.2∶1),20~50岁多发,上尿路结石多于下尿路结石(5.4∶1)。结石中草酸钙检出率达82%,尿酸盐55.2%,磷酸钙48.6%,磷酸镁铵与碳酸磷灰石则多见于泌尿系感染病例,胱氨酸结石少见。结论化学常量法分析泌尿系结石简便、快捷、准确。结石成份分析对于了解结石成因、预防结石复发具有一定的意义。     

泰素蒂加顺铂治疗进展期NSCLC的临床研究

目的观察泰素蒂加顺铂方案治疗进展期非小细胞肺癌的临床疗效、毒副作用。方法收集可评价疗效的进展期非小细胞肺癌50例,以泰素蒂加顺铂方案进行化疗,泰素蒂75 mg/m2静脉滴注,第1天;顺铂25 mg/m2～30 mg/m2静脉滴注,第2天～第5天,每3周为一个周期,2～3周期后评价疗效和毒副反应并随访。结果50例患者中,总有效率为50.0 %,其中初治病例为53.1 %,复治病例为44.4 %,初复治病例间差异无显著性(P >0.05)。中位缓解期为5个月。中位生存期为9.5个月,1年生存率为61.0 %。毒副反应主要为骨髓抑制,白细胞下降达Ⅲ度、Ⅳ度者52.0 %,血小板下降达Ⅲ度、Ⅳ度者为14.0 %。血红蛋白下降不严重。其他毒副反应还有脱发、过敏反应、水钠潴留、静脉炎、末梢神经炎、口腔炎、腹泻等,但发生率均较低。结论泰素蒂加顺铂方案治疗进展期非小细胞肺癌,特别是复发病例,临床疗效比较满意,毒副反应能够耐受。辅以G蛳CSF可防治重度的骨髓抑制,有较好的临床应用价值。

Multicentric fibromatosis of familial inheritance

This is an unusual case presentation of a young woman with a clinical history and course simulating juvenile hyaline fibromatosis, but without hyalinization in the stroma. Because of the age of onset, the apparent familial inheritance, the nonaggressive and nonregressive tumor traits, the disease cannot be classified as multicentric fibromatosis. Therefore, we are referring to this case as multicentric fibromatosis with familial inheritance, a previously unreported entity to our knowledge.     

Observations on pathological and histochemical changes in piglet livers infected with Taenia saginata asiatica

To study the pathological and histochemical characteristics of lesions in piglet livers infected with Taenia saginata asiatica (T. saginata asiatica) throughout the different stages, piglets were fed with eggs of T. saginata asiatica and raised in isolation in an animal center to establish the T. saginata asiatica infection model with normal piglets as control. The pathological changes in the piglet livers were observed after the infection using liver sections stained with hematoxylin and eosin. Histochemical methods were used to check the changes in lipid, glycogen and protein content in the liver. The data collected by image analysis were analyzed statistically with Statistical Package for the Social Science. The results show that T. saginata asiatica-exposed piglets were indeed infected. Inflammatory reactions began on the fourth day and progressed rapidly. Kupffer cell hyperplasia, hepatic hydropic degeneration and ballooning degeneration were found in the 10th–20th days after infection. Hepatic central veins and hepatic sinusoids were dilated and congested. Spotty necrosis occurred in some local liver tissues. In the 40th–60th days, granulomatous reactions and mild hepatocirrhosis were the main lesions. In the 70th–80th days, hepatocirrhosis and bile duct proliferation were observed in the liver. In the different stages, lipid drops were increased while glycogen and protein levels were decreased to some degree. There was a significant difference in metabolism between the infected group and the control group (P < 0.01). It is concluded that pigs are the favorable intermediate host of T. saginata asiatica and its infection can result in serious pathological and histochemical lesions in host organs.

~(125)Ⅰ眼镜蛇毒及抗眼镜蛇毒血清在小白鼠体内分布的比较观察

用氯胺-T法125I标记眼镜蛇毒示踪液及抗眼镜蛇毒血清。小白鼠分二组，用125I-眼镜蛇毒、125I-抗眼镜蛇毒血清分别给小白鼠尾静脉注射，于注射后的不同时间测定血、颈部肌肉、肝、肺、肾、心等脏器放射性分布。结果发现：125I-眼镜蛇毒在肌肉及肝、肺等器官中于注射后2小时过高峰，在肾脏中浓度高，在脑未见放射性分布，抗眼镜蛇毒血清与眼镜蛇毒分布相似但在肌肉及肺脏有更高的分布。证明抗眼镜蛇毒血清能跟踪分布眼镜蛇毒。
