沙培林增强人腹腔巨噬细胞抗癌免疫功能的研究

目的:探讨腹腔内注射沙培林增强人腹腔抗癌免疫功能的机制。方法:72例早中期胃肠道肿瘤患者术前48h和24h腹腔内分别注射生理盐水和5KE的沙培林,术中采集腹腔内巨噬细胞,计数并测定乳酸脱氢酶(LDH)和酸性磷酸酶(ACP)的活性,巨噬细胞吞噬活力,一氧化氮(NO)的分泌以及对人胃癌MKN1细胞的细胞毒性进行分析。同时采集大网膜,对大网膜乳斑的数量和面积进行观察。结果:沙培林显著增加腹腔巨噬细胞(PMΦ)的数量和NO的分泌,增强LDH和ACP的活性,吞噬活力,以及抗癌细胞毒性,也显著增加了大网膜乳斑的数量和面积。结论:腹腔内注射沙培林可显著增加人大网膜乳斑的数量和面积,并因此增加PMΦ的数量,增强PMΦ的活性。因而增强了腹腔巨噬细胞的免疫功能。     

三康胶囊对高原移居者运动后NO乳酸及血氨的影响

目的探讨三康胶囊对高原人体运动后一氧化氮(NO)及其合酶(NOS)、乳酸(BLA)、血氨(Ammo)的影响.方法选择进驻海拔3 700 m高原1年的10名健康青年,口服三康胶囊15 d,在服药前后分别采用功量自行车进行渐增负荷运动,测定其血清 NO、NOS、BLA及Ammo含量.结果服药后较服药前运动后NO水平[(101.02±6.49) Vs (77.10±8.11)]和NOS活性[(71.40±7.23) Vs (56.29±6.28)]均增高, BLA[(7.58±0.79)Vs (6.13±0.74)]和Ammo[(80.11±9.44)Vs (69.38±8.86)]降低,有非常显著性差异(P＜0.01).结论 三康胶囊能增强高原移居者运动后NOS活性,加速乳酸清除,减缓运动疲劳的发生.     

Thirty-two Cases of Acne Treated with Blood-letting Puncture,. Cupping and Chinese-Drug Facemask

To observe the therapeutic effect on acne treated with blood-letting puncture,cupping and Chinese-drugfacemask.Thirty-two patients with acne were treated with above-mentioned therapeutic method.Cure,improvement and ineffectiveness were respectively found in 24,7 and 1 case,with a curative rate of 75.0%and a total effective rate of 96.8%.The combination of blood-letting puncture,cupping and externalapplication of Chinese-drug facemask is effective in treating acne.     

云南省600例0~5岁儿童维生素A缺乏调查

目的:了解云南省城乡0~5岁儿童维生素A营养状况及影响因素。方法:省、地、县随机整群抽取600例儿童,采用微量荧光光度法检测VitA含量。结果:VitA缺乏发生率16·17%,地、县明显高于省会城市;0岁儿童明显高于其他年龄组;腹泻儿童明显高于正常儿童;VitA缺乏的影响因素:近1周内进食鸡蛋、奶类制品、鱼虾类、肝类、黄绿色蔬菜、鱼肝油等食物有利于维生素A的吸收,急性呼吸道感染、发烧与维生素A缺乏发生率差异不明显。结论:维生素A缺乏发生率城市明显低于农村地、县两级,说明维生素A缺乏防治工作重点在农村,特别是0岁儿童,防治的主要措施是采取合理膳食,均衡营养,控制腹泻流行。     

小脑幕切迹疝CT诊断及临床价值

目的:探讨小脑切迹疝的CT早期表现及临床应用价值。方法:对临床诊断为小脑切迹疝75例CT表现和临床分型进行分析。结果:小脑切迹疝CT表现鞍上池、脚间池、环池、四叠池缩小变形或闭塞分别占52/75、52/75、47/75、20/75。中脑变形移位33/75,脑室系统扩张(侧、三脑室)7/75,蛛网膜下腔出血占26/75。临床分前疝、后疝、全疝、环疝,各占24/75、31/75、16/75、4/75。行脑定位抽吸术治疗27例,外科手术34例。结论:小脑切迹疝CT表现具有特征性,脑疝早期可无典型脑疝临床表现,而CT检查可早期诊断,且优于其他检查。     

Cathodes for fuel cells using proton-conducting Li2SO4–Al2O3 electrolyte

The performances of three widely different cathode materials (Pt, strontium-doped lanthanum manganite (LSM), and NiO) have been compared for use with proton conducting Li₂SO₄–Al₂O₃ composite electrolyte, using H₂S–air and H₂–air fuel cells operating at 600 °C. Surface analysis and electrochemical techniques were used to characterize fresh and used electrode materials. Pt or LSM cathodes each became covered with Li₂SO₄ and Al₂O₃ and, as a consequence, the fuel cells showed poor performance. In contrast, the NiO cathode catalyst did not become covered with Li₂SO₄ and good fuel cell performance was achieved. Exceptionally good current densities of over 100 mA/cm² and power densities of over 30 mW/cm² were obtained for H₂S–air fuel cells having Mo–Ni–S anode catalysts. Slight agglomeration of NiO particles during fuel cell operation had only a minor effect on performance.     

高血压家系802人的高血压患病率、知晓率、治疗和控制状况调查

目的了解高血压家系人群高血压患病率、治疗率和控制率特点。方法用整群随机抽样调查的方法调查高血压家系高血压的流行和控制情况，分析比较相关指标的差异。结果家系成员高血压患病率为55．86％，存在危险因素聚集现象。高血压的知晓率、治疗率、控制率分别为79．46％、62．72％、19．64％。结论该地区高血压家系高血压患病率较高，遗传因素是重要原因。虽高血压控制水平较高，但需加强高血压的一级预防。
