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。     

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。     

彩色多普勒组织显像对川崎病心肌病变的诊断价值

应用彩色多普勒组织显像(DTI)比较观察10例川畸病(KD)患儿与143例正常儿童二尖半环、左室壁及心内膜不同时相运动速度的变化.结果显示10例KD患儿的二尖半环舒张早期运动速度(MVR-DeV)明显降低,与对照组比较有显著差异,同时KD患儿M VR-DeV的异常率显著高于DTI的其它检查指标.     

Emergency free flaps to the type IIIC tibial fracture

Type IIIC tibial fractures are complex injuries involving extensive bone and soft-tissue devascularization that result in a high percentage of complications and ultimate amputation. An emergency free flap transfer not only may salvage the limb but also may improve the aesthetic and functional results of reconstruction by placing the injured structures in a well-vascularized bed. Two cases of type IIIC tibial fracture were treated in this manner, and we present our experience with a 30-month follow-up of one patient and a 6-month follow-up of another patient.

四叠体池蛛网膜囊肿

目的:探讨四叠体池蛛网膜囊肿的临床特征和治疗方法。方法:对11例四叠体池蛛网膜囊肿进行了回顾性总结分析。所采用的手术方法有:①脑室分流手术;②囊肿-腹腔分流术;③囊肿切除;④囊肿切除加囊肿-脑池分流术,或囊肿部分切除(即囊肿开窗术),或囊肿切除加脑室-脑池分流术。结果:其主要临床表现以颅内压增高症和中线综合征为主。上述方法中单纯囊肿壁切除只能使部分病人的病情缓解,脑室分流或囊肿切除加脑室分流手术的疗效较好。结论:四叠体区蛛网膜囊肿常合并梗阻性脑积水,单纯囊肿切除不能解除多数病人的梗阻性脑积水。作者根据囊肿是否与蛛网膜下腔相通提出:对交通性蛛网膜囊肿采用单纯性脑室分流术,对非交通性者采用囊肿切除加脑室分流手术的治疗方法。
