不同起搏模式对病人生存质量影响的调查研究

[目的]探讨不同起搏模式对病人生存质量（QOL）的影响。[方法]以健康调查问卷（SF一36量表）对112例不同起搏模式病人进行问卷调查，比较3种起搏模式下病人的QOL水平。[结果]除机体疼痛、角色情绪2个维度外其余6个维度（生理功能、角色限制、活力、社会功能、精神健康、总体健康）3种起搏模式间比较差异有统计学意义（P〈0．05）。[结论]应用AAI型、DDD型起搏器的病人生存质量优于VVI型起搏。     

聚氯乙烯增塑糊流变行为的研究——Ⅳ.表面活性剂的影响

本文研究了各类表面活性剂对聚氯乙烯增塑糊流变行为的影响。阴离子表面活性剂使其增塑糊有较高致流值,呈明显假塑性流动;阳离子和非离子表面活性剂使其增塑糊有低的表观粘度,接近牛顿型流动。测定了聚氯乙烯粒子表面的Zeta电位和接触角,并讨论了表面活性剂影响增塑糊流变性能的机理。     

PREVIOUS INTRAVENOUS CHEMOTHERAPY DOES NOT ALTER RESPONSE RATE OR SURVIVAL TIME OF PATIENTS WITH HEPATIC METASTASES FROM COLORECTAL CANCER TREATED BY HEPATIC ARTERY CHEMOTHERAPY

Background : The present paper addressed the issue of whether pretreatment with intravenous (IV) chemotherapy affects response rate or survival in patients receiving hepatic artery chemotherapy (HAC). Methods : Case note reviews of 164 patients treated in a teaching hospital from June 1990 to July 1996 were carried out. Results : The response rate and carcino-embryonic antigen (CEA) fall in the two groups was almost identical. There was a nonsignificant survival advantage in the non-pretreatment group. Conclusions : Previous administration of IV chemotherapy did not affect the CEA response of patients receiving HAC.     

钚促排药物的设计与合成

利用仿生化学的原理，本文设计并合成了两个儿茶酚胺类和两个羟基吡啶酮类八配位的螯合剂，初步动物试验表明，具有较强的钚促排能力。     

带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎

目的：阐明带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎的疗效。材料和方法：对４２例４８髋晚期类风湿性髋关节炎病人采用以旋股外侧血管降支为蒂的股前外侧筋膜瓣移植行患髋成形术。结果：术后随访４～１０．５年，平均４．５年，髋关节活动范围术前平均１６．５°，术后２２８．６°，按照Ｃｈａｒｎｌｅｙ和吴之康人工髋关节置换术后的疗效评定标准，优良２９髋、很好１３髋、好６髋，尚可、差、很差无。结论：患者年龄在１５～４０岁之间为合适的治疗年龄。与人工髋关节置换术相比，本方法对髋关节正常结构破坏小；一旦手术失败仍可选用其它治疗方法弥补；且并发症少、费用低、远期效果好。     

Paraffinoma in the urinary bladder: CT findings.

A case of a paraffinoma in the urinary bladder is presented. Plain radiography and intravenous urography showed a low attenuation filling defect in the urinary bladder, and CT demonstrated a lobulated fat-attenuation mass floating in the urinary bladder.     

医学美学与美容医学的整体学科研究

回顾医学美学与美容医学形成独立的学科系统的十多年来的发展历程，认为这个新兴学科在“整体学科”方面还存在一些学术问题有待人们进一步探讨。并认为，所谓“整体学科研究”是遵循该学科发展的内在规律所进行的各项研究的总和，是该学科发展的灵魂。学者们的任务在于：通过“整体学科研究”寻求其学科内在规律，经一代代同道有志者坚持不懈的努力，达到学科完善的目的。     

Sonographic appearance of Krukenberg tumor from gastric carcinoma

Sonographic findings in 16 cases of Krukenberg tumor from gastric carcinoma were analyzed. The patients' ages ranged from 25 to 52 years (mean 42 years). The tumor involved both ovaries in 14 patients with asymmetrical masses in 9 of 14 cases. Ascites was noted in 15 cases. Echogenicity of the tumor varied from solid to predominantly cystic: solid in 8, mixed in 6, and predominantly cystic in 2 cases. Solid masses tended to be smaller than mixed or cystic masses. The primary gastric carcinoma had been diagnosed before emergence of the tumors in only 7 cases. The findings suggest that in relatively young patients with ovarian mass, particularly bilateral tumors, careful evaluation for gastrointestinal tract involvement should be done.
