小儿氨基酸注射液治疗胎儿宫内发育迟缓的探讨

经临床鉴定静脉内注射小儿氨基酸对治疗胎儿宫内发育迟缓具有肯定效果。在Ｂ超监视下，使用小儿氨基酸的孕妇组于用药期间，胎儿生长参数ＢＰＤ和ＨＣ显著高于使用成人氨基酸的孕妇组。１０例足月娩出胎儿体重均达到甚至超过２．５ｋｇ。由此得出结论：使用小儿氨基酸注射液对于改善胎儿宫内发育迟缓优于成人氨基酸。     

直肠癌患者手术前后凝血状态变化的研究

目的：通过研究直肠癌患者凝血与纤溶系统的变化，观察其与手术切除与否、淋巴结转移、细胞分化程度等的关系。方法：选取直肠癌患者58例，于术前及术后两周检测PAGT、PT、APTT、TFPI、D－二聚体、t-PA:a等指标；同期52例非肿瘤病人作为对照组。结果：直肠癌患者较对照组血小板聚集增强（P＜0．05），凝血酶原时间、活化部分凝血活酶时间明显缩短，组织因子途径抑制物降低（P＜0．05），D－二聚体和t-PA:a显著升高（P＜0．01），存在淋巴结转移和低分化腺癌者尤为明显（P＜0．05或P＜0．01），手术切除后有所改善。结论：直肠癌患者处于高凝和纤溶亢进状态，在淋巴结转移和癌细胞分化差的病人中尤为明显；应用抗凝和抗纤溶药物可能对直肠癌的预防有一定作用。     

全雄激素阻断治疗晚期前列腺癌

为了评价全雄激素阻断治疗晚期前列腺癌的疗效，采用双侧睾丸切除、Ｆｌｕｔａｍｉｄｅ和Ｆｉｎａｓｔｅｒｉｄ联合治疗Ｄ２期前列腺癌病人５例。随访１５～２０个月，结果ＰＳＡ均正常，前列腺体积缩小６１．２％～６９．３％，有显著性差异（Ｐ＜０．０１），骨转移灶缩小、部分消失，积水肾脏完全恢复正常，所有病人治疗后全部有效。表明全雄激素阻断对晚期前列腺癌有良好的治疗效果。提出在三个层次上阻断雄激素治疗晚期前列腺癌的策略。     

预防性应用钙拮抗剂对缺血大鼠心肌细胞和红细胞内钙变化的影响

利用大鼠缺血模型观察预防性应用钙桔抗剂尼莫地平对大鼠缺血心肌和红细胞内钙的影响发现，缺血时大鼠心肌细胞、心肌组织和红细胞内均有钙积聚，红细胞膜钙泵活性下降；缺血前30分钟给予尼莫地平可使红细胞内钙恢复至正常水平，红细胞膜钙泵活性升高；心肌细胞和心肌组织内钙虽较缺血鼠降低，但仍高于对照组。提示：（1）缺血时细胞的钙内流可能是全身性的；（2）预防性应用尼莫地平可阻滞或减轻细胞内钙超载，同时还可保护细胞膜膜泵活性。     

The epidemiology and surveillance of blood lead in Taiwan (R.O.C.): A report on the PRESS-BLL project

 To monitor the lead hazards in industries and to investigate the prevalence of elevated blood lead levels (BLLs) in lead-exposed workers, a lead surveillance system (PRESS-BLLs) has been established and operated in Taiwan, Republic of China, since July 1993. A cohort of lead-exposed workers who received a periodic annual health examination at 55 accredited hospital laboratories was constructed. A total of 9807 separate BLL measurements were reported to the system in 1994. The mean BLL was 15.8 μg/dl in male workers and 11.6 μg/dl in female workers. The mean BLL of lead-exposed workers was significantly (P<0.05, z-test) higher than that of the general Taiwanese population (8.6 μg/dl for males and 6.7 μg/dl for females). In addition, the BLLs of 983 (10.0%) workers exceeded the regulatory action level (40 μg/dl for males; 30 μg/dl for females). The workplaces and homes of 57% of the workers with elevated BLLs were thoroughly investigated to determine the sources of lead contamination. These actions identified the causes of elevated BLLs and set up strategies to reduce workers’ lead exposure. The establishment of this occupational lead surveillance system represents a method for monitoring of lead hazards from occupational and environmental settings to prevent lead poisoning. The information acquired from the system can help in the setting up of a priority of prevention and the development of control measures. It is also useful for further monitoring of changes in the BLLs of the lead-exposed-worker cohort. The Health Department of Taiwan can use this information to evaluate the effectiveness of current industrial hygiene practice. Subjects with elevated BLLs have been medically treated and placed on long-term follow-up for sequelae. Received: 2 September 1996/Accepted: 29 November 1996     

胃癌患者胃液可溶性白细胞介素-2受体初步研究

应用双抗体夹心ELISA法对87例消化道疾病患者胃液可溶性白细胞介素-2受体(sIL-2R)水平进行测定。结果表明,胃癌患者胃液sIL-2R水平明显高于慢性浅表性胃炎及十二指肠溃疡患者(P相似文献   

慢性HBV感染患者HBsAg亚型分析

对包括慢性肝炎、肝炎肝硬变和原发性肝癌在内的１００例慢性ＨＢＶ感染者作了ＨＢｓＡｇ亚型分析。结果显示，在这组病例中ａｄｒ亚型占６１％，ａｄｗ占３３％，ａｙｒ占２％，ａｄｗｒ占４％。ａｄｒ亚型有随年龄增长更占优势的趋向。ａｄｒ和ａｄｗｒ亚型感染者ＨＢｓＡｇ滴度较ａｄｗ组显著增高，且ｅ抗原阳性率亦较高。上述发现提示，具有ａｄｒ和ａｄｗｒ亚型的ＨＢＶ株可能具有较强的复制活性，不易被清除，从而导致受感染者

对氯烯雌酚醚防治雌性大鼠去势后骨丢失的评价

目的：了解氯烯雌酚醚对去势雌性大鼠骨代谢的影响。方法：鼠龄７０天的Ｗｉｓｔａｒ雌鼠４８只，分别予假性手术与注射用油（ＳＶ组）、去势与注射用油（ＯＶ组）、假性手术与氯烯雌酚醚（ＳＥ组）及去势与氯烯雌酚醚（ＯＥ组）等处理，双侧卵巢去势或假性手术后７天，于每晚腹腔注射氯烯雌酚醚或注射用油４ｍｌ／ｋｇ，共４５天。处死大鼠时，测定子宫湿重，同时收集第１２胸椎和左胫骨制成脱钙骨切片，行骨组织形态计量学测定。结果：４组间子宫重量差异均有显著性。骨组织形态计量学显示，（１）ＯＶ与ＳＶ、ＳＥ及ＯＥ组间差异有显著性；（２）ＯＥ、ＳＥ和ＳＶ组间差异无显著性。结论：氯烯雌酚醚能抑制Ｗｉｓｔａｒ雌鼠去势后的骨丢失，减缓去势后的子宫萎缩，对骨骼有雌激素样的保护作用。     

Clinical observation of Qi deficiency syndrome in 72 patients with chronic obstructive pulmonary disease treated with Yiqi Mianyi Granule

Seventy-two patients of chronic obstructive pulmonary disease (COPD) of Qi deficiency syndrome with abnormal immune indices were treated with Yiqi Mianyi Granule (YQMYG) and the efficacy was compared with that of 30 cases treated with Zhenqi fuzheng Granule (ZQFZG) for control. Results showed that the markedly effective rate of symptomatic improvement of Qi deficiency in YQMYG group was 65.3%, the total effective rate 93.1%. 88.6% of the immune indices lower than normal were corrected and 43. 7% of them were normalized, while for indices that were higher than normal the rate were 78.2% and 52.9% respectively. These results suggested that YQMYG could improve symptom of Qi Deficiency markedly, strengthen cellular immunity and regulate immune dysfunction. Its therapeutic efficacy was obviously superior to ZQFZG (P<0.Q5).
