上海市少年儿童住院医疗保险费用分析

本文研究了上海市少年儿童住院医疗保险的费用水平、特点和影响因素。研究结果表明:手术与否、患者年龄、就诊地点、家长医疗保健制度和医院等级的差异造成次均费用的差异;次均费用构成比较合理,药品费比例低于全市水平。病种费用居前三位的是白血病、肺炎和先天性心脏病;特殊病种占总医疗服务人次的4.90％,而医疗费用占总费用的32.57％。     

5km重复低压缺氧对小鼠肝脏及脾脏中微量元素的影响

目的 探讨5km重复低压缺氧对小鼠肝脏及脾脏中微量元素的影响。方法 将小白鼠分为5km重复低压缺氧实验组及地面对照组。实验组每天进行5km重复低压缺氧30min,连续7d后，处死小鼠，取肝脏、脾脏烘干至恒重，采用火焰原子吸收法测定锌、铜、铁。结果 5km重复低压缺氧小鼠肝脏中Cu、Fe含量与对照组比较有显差异(P＜0．05)；脾脏中微量元素Fe的含量与对照组比较有显性差异(P＜0．05)。结论 5km重复低压缺氧，使肝脏中Fe、Cu含量降低，脾脏中Fe含量升高。     

彩色多普勒在心脏起搏器综合征诊断中的应用价值

目的 :探讨运用彩色多普勒血流显像 (CDFI)并结合心电图 (ECG)诊断起搏器综合征 (PMS)的临床价值。方法 :对具有详实临床及ECG资料的心室按需 (VVI)起搏器安置患者 6 0例及对照组 4 8例进行CDEI检查 ,观察起搏组与对照组的三尖瓣返流 (TR)的发生率、返流程度 ,并分析二者之间的相关性。结果 :起搏组出现逆传P波 (即PMS阳性 )者 15例 ,CDFI检测出现TR者 2 0例 ,明显高于对照组 ,且PMS阳性者TR发生率明显高于PMS阴性者 ,表明安置VVI起搏器后出现逆传P波与TR的发生相关性良好。结论 :CDFI对PMS的诊断具有重要意义 ,尤其将ECG与CDFI结合应用有助于诊断率的提高。

血清载脂蛋白A1,B100含量测定在冠心病诊断中的价值

分别采用联合火箭免疫电泳技术和酶法对49例冠心病患者和50例健康人血清载脂蛋白 A_1(apoA_1),载脂蛋白 B_(100)(apoB_(100)),以及血清总胆固醇(TC)、甘油三酯(TG),高密度脂蛋白胆固醇(HDL—ch)的含量进行了测定。结果冠心病患者血清 apoB_(100)(0.99±0.26g/L)明显高于健康人(0.62±0.18g/L);而apoA_1/apoB_(100)比值(1.22±0.35)则明显低于健康人(2.12±0.49);TC,TG,HDL-ch 的含量亦有统计学意义。提示,在预示冠心病危险因素的各种脂类及脂蛋白中,以 apoB_(100)增高 apoA_1/apoB_(100)比值降低最为灵敏,最为准确,且高于单纯测定TC,TG 和 HDL-ch。

1-stage reconstruction of microtia associated with hemifacial soft tissue aplasia

Four cases of microtia association with hemifacial aplasia were repaired by one-stage reconstruction. The operations included external ear reconstruction and correction of facial deformity with free vascularized dermis fat flaps. All were successful, the results were satisfied. The method and the device of the operation are described in detail. The advantages of the technique are discussed.     

~(125)碘-绒毛膜促性腺激素的电泳纯化及分析

标记抗原在贮存过程中,由于受幅射分解和脱碘影响而使免疫活性和生物活性降低。我们对自制的~(125)碘-绒毛膜促性腺激素进行了实验观察。结果显示:贮存1月后,其免疫活性和生物活性分别降低了33.1％和44.0％;经电泳纯化后的标记物的免疫活性和生物活性明显提高,分别达到了最初的90.5％和95.3％。

REGULATING FUNCTION OF COENZYMIZATION AND DECOENZYMIZATION OF THE LACTATE DEHYDROGENASE ISOZYMES IN THE MOUSE TISSUES DURING HYPOXIA

Objective. To study the characteristics of changes of LDH enzyme patterns of mice under slight hypoxia.Methods. Mice treated with artificial hypoxia, various tissues were made for the test of LDH enzymatic activity by the specific staining technique. LDH (1 -5) relative percentage enzymatic activity (RPEA) were measured with CS-910 dual-wavelength thin layer chromatography scanner.Results. The RPEA of LDH isozymes of various tissues after slight hypoxia shifted to the isozymes LDH1 and LDH2, whose principal subunits are H subunits, and the RPEA of LDH,(H4), LDH2(H3M) increased, while RPEA of LDH5(M4) in various tissues decreased prominently except the cardiac muscle, and that of LDH4(HM3) decreased as well. After polyacrylamide gel electrophoresis (PAGE) of the hypoxia treated cardiac muscle specimen was made, activity subbands originated regularly in the isozyme patterns of LDH, with the regularity of LDH1 (0 subband), LDH2 (0-1 subbands), LDH3 (0-2 subbands), LDH4 (1-3 subbands), LDH5 (2-4 subbands).
