Decreasing ascorbate intake does not affect the levels of glutathione, tocopherol or retinol in the ascorbate-requiring osteogenic disorder shionogi rats.

Levels of glutathione in liver and kidney, and other nutrients in plasma were evaluated in male and female ascorbate-requiring osteogenic disorder Shionogi (ODS) rats fed semipurified diets in which the concentrations of ascorbate were gradually decreased from 1965 to 180 mg/kg. Plasma ascorbate levels in ODS rats were unaffected when ascorbate levels in the diet were decreased from 1965 to 768 mg/kg. However, plasma ascorbate levels decreased progressively when levels of ascorbate in the diet were decreased from 527 to 180 mg/kg. Plasma ascorbate levels decreased up to 77% when the dietary ascorbate concentration decreased from 1965 to 180 mg/kg. Ascorbate levels in liver and kidney fell as much as 60-70% when the dietary ascorbate levels were reduced from 1965 to 180 mg/kg. However, the glutathione levels in these tissues were not affected. Plasma retinol and vitamin E levels were not affected by decreasing dietary ascorbate intake. Total cholesterol levels increased significantly in female rats as dietary ascorbate intake declined. Levels of glycated hemoglobin decreased significantly when dietary ascorbate levels decreased from 1965 to 527 mg/kg. This study suggests that levels of vitamin E, retinol and glutathione are not affected by decreased dietary intake of ascorbate under nonscorbutic conditions, whereas elevated ascorbate intake is associated with a decrease in levels of plasma cholesterol in female ODS rats. However, excessive intake of ascorbate may be associated with elevated glycation of hemoglobin. To achieve the maximal health benefit of ascorbate supplementation, further studies are necessary to define optimal ascorbate intakes.

为 ２３ 例喉癌患者行喉大部分切除术,采用下列方法重建喉功能,（１）重建声门关闭功能;（２）重建会厌覆盖功能;（３）保留或重建梨状窝;（４）保护喉上神经和喉返神经;（５）保持宽大的下咽部;（６）切断环咽肌。２３ 例中２１ 例获得随访,术后均能发音,术后２～４ 周拔除鼻饲管,无误吸及呛咳。５ 年生存１１ 例,生存率 ４７８％ 。     

化疗在晚期肺腺癌治疗中的作用

目的：探索晚期肺腺癌患者化疗疗效和对化疗的耐受性,化疗后生活质量变化和生存期。材料与方法：回顾分析1992－11~1995-04,经病理确诊为肺腺癌。按UICC分期为Ⅲb、Ⅳ期,Kamofsky评分≥60,连续完成2程以上的以铂类药物为主的联合化疗方案治疗患者。结果：化疗有效率3．1％,化疗后Kamofskv评分不变者43．8％,升高40．6％。下降≥10分15．6％,Ⅲb期中位生存期13月,Ⅳ期10月。结论：全身状况较好无化疗禁忌证的晚期肺腺癌患者,给予适当的联合化疗可使部分患者病情改善,生活质量提高。     

孕期沙眼衣原体、支原体感染治疗效果与胎儿状况相关性研究

研究孕期沙眼衣原体,支原体感染治疗效果与胎儿生长发育的关系。方法应用免疫荧光法对６００例孕妇宫颈分泌物行沙眼衣原体,支原体属抗原检测,阳性者对配偶行尿道分泌物检测,孕妇阳性者以口服红霉素治疗,观察治疗过程中,胎儿异常及低休 儿发生比较及与配遇感染的关系。     

藏药七十味珍珠丸对动物出血和凝血时间的影响

藏药七十味珍珠丸（RNSP）灌胃给药（ig）给药0．5g／kg和1g／kg对大、小鼠的出血时间和凝血时间无影响;对“血瘀”模型大鼠的凝血时间和血小板数也无统计学差异。而ig给药2g／kg对延长小鼠出血时间的作用非常明显。     

功能性消化不良患者的心理测评及抗抑郁治疗

目的：探讨心理异常与功能性消化不良(FD)发病的关系，并探讨抗抑郁治疗对FD患者的疗效。方法：采用焦虑自评量表(SAS)和抑郁自评量表(SDS)对100例FD患者及100名健康对照组进行心理测评，比较2组焦虑、抑郁的发生率；采用评分法对FD患者进行症状评分，随机将心理测评异常的FD患者分为常规组及综合组，分别给予抗消化不良药物及在此基础上加用抗抑郁药文拉法辛治疗，比较2种治疗方法的总有效率；将综合治疗有效的病例随机分成维持组及停药组，维持组继续给予文拉法辛维持量治疗，观察6mo中2组的复发率。结果：FD组患者焦虑及抑郁状态发生率明显高于健康组；综合组有效率高于常规组；文拉法辛6mo维持治疗复发率低于疗程结束后即停药者。结论：焦虑、抑郁的心理异常是FD发病的危险因素，但用抗抑郁治疗可提高FD患者常规治疗的有效率，6mo维持治疗能有效降低FD复发率。

妊高征患者胎盘组织中FasL的表达及其意义

目的　探讨FasL在妊高征患者胎盘组织中的表达是否异常 ,进一步从免疫学角度分析妊高征的发病机制。方法　 2 0 0 1年 11月至 2 0 0 2年 7月 ,采用免疫组织化学SP法检测 2 0例正常孕妇 (对照组 ) ,6 5例妊高征患者 (妊高征组 ,其中轻度 2 2例、中度 2 0例、重度 2 3例 )胎盘组织中FasL表达强度。结果　FasL主要表达于胎盘绒毛滋养细胞 ,妊高征组胎盘绒毛滋养细胞及蜕膜组织细胞FasL表达强度明显低于对照组 (P <0 0 1,P <0 0 5 )。结论　妊高征患者胎盘组织FasL表达减少 ,母胎免疫耐受机制遭到破坏 ,引发胎盘绒毛发育不全、功能下降等一系列免疫病理改变 ,最终可能导致妊高征及其并发症的发生。
