2004年黑龙江省富裕县克山病病情监测分析

目的了解克山病国家级监测点富裕县永进村2004年克山病患病和发病情况。方法对监测点区居民进行体检和心电图检查．对病人和可疑病人进行胸部X线片检查。结果永进村2004年无新发各型克山病病例。在检查的636人中，检出克山病现患病人16例，总检出率2．5％。其中潜在型10例，慢型6例，检出率分别为1．6％和0．9％。结论富裕县永进村克山病病情稳定，无新发病例，但继续进行病情监测、观察现患病人的病情变化．仍然是克山病监测的重点。     

硒和维生素E对大鼠的抗氧化作用

目的研究硒和维生素E(VE)在抗氧化损伤过程中的单独及联合作用。方法80只健康雄性Wistar大鼠,按体质量随机分为4组(每组20只):低硒低VE组、低硒补VE组、补硒低VE组、补硒补VE组。饲养3个月后,乙醚麻醉活杀,采腹主动脉血,离心制备血浆,测定各组大鼠谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)、总抗氧化能力(T-AOC)、活性氧(ROS)和丙二醛(MDA)水平。结果①与低硒组比较(不考虑VE),补硒组SOD、GSH-Px、T-AOC活性高于低硒组,而补硒组MDA、ROS水平低于低硒组,差异均有统计学意义(P<0.01);与低VE组比较(不考虑硒),补VE组SOD、T-AOC活性高于低VE组,而GSH-Px、MDA水平低于低VE组,差异均有统计学意义(P<0.05)。②在对SOD、GSH-Px、T-AOC活性及MDA、ROS水平影响方面,硒和VE的主效应分别为:23.05、6.75 kU/L;350.21、-20.73μmol/L;1.99、1.67 kU/L;-0.89、-0.78μmol/L;-199.71、-17.43 kU/L。③硒与VE的协同作用在提高SOD、GSH-Px活性方面比较明显(P<0.05)。结论补充硒和VE能够增强机体抗氧化能力,防止脂质过氧化损伤。但二者的作用强度不同,在补硒0.25 mg/L和补VE 0.2/kg条件下,硒的抗氧化作用明显高于VE,并且硒和VE在提高抗氧化能力方面有明显协同作用。     

克山病患者抗氧化能力测定

Objective To explore the relationship between myocardial damage and antioxidant capacity in vivo of Keshan disease patients and to analyze the possible pathogenesis. Methods In the period from 2005 to 2006, 41 chronic and latent Keshan disease cases were chosen as the case group from such serious endemic areas as Yongjin Village, Xinfa Village of Fuyu County, Fuan Village of Shangzhi County, Xinghuo Village of Wudalianchi County, 61 healthy people from the same area as internal controls, 48 healthy people from Xianglansan Village of Wangkui County, an un-endemic area, as external control. Fasting peripheral venous blood was collected from all the people. And blood selenium, glutathione peroxidase(GSH-Px) and suporoxide dismutase.(T-SOD) activities, malondialdehyde (MDA) levels were examined. Results Blood selenium level of the patient group [(34.80±13.30) μg/L], GSH-Px[(104.10±34.19)U/L]and T-SOD[(92.16±17.98)×103 U/L]actives were significantly lower than the internal control group [(41.24±13.57)μg/L, (118.57±25.49)U/L, (104.82±13.56)×103 U/L]and the external control group [(48.33±16.51)μg/L, (155.00±24.01)U/L, (108.48±12.73)×103 U/L], respectively, with a statistically significant difference(all P < 0.05). MDA level of the patient group[(7.12± 1.37)μmol/L]was higher than that in the internal control group[(5.36±1.18)μmol/L]and the external control group[(5.22±0.83)μmol/L]with a statistically significant differences(both P < 0.05). The blood selenium level, GSH-Px activity of internal control group was resoectively lower than that in the external control group, the differences being statistically significant(beth P < 0.05). Conclusions Selenium deficiency may lead to reduced antioxidant capacity and enhanced oxidative damage in Keshan disease patients in vivo. There may be a certain relationship between oxidative stress disorder and myocardial damage of Keshan disease.

乡村医生基本专业素质的循证研究

乡村医生的最后学历与年龄、工作年限之间都无相关关系。抗生素的正确用法是什么?和感冒的治疗原则是什么?这是两个比较有代表性的问题。分析结果显示，乡村医生对这两个问题的回答正确率分别为14．0％和59．8％。结论认为，他们的医学知识存在一定程度的缺陷，主要跟他们的最后学历和每次接受培训的持续时间有关。改善乡村医生队伍的基本专业素质至关重要。     

孤独症儿童混合面部表情识别及面孔性别区分能力研究

【目的】 测试孤独症儿童混合面部表情的识别能力及通过眼和嘴对面孔性别进行区分的能力。 【方法】 采用自制计算机系统对32例孤独症儿童和32例正常儿童进行测试并分析,以正确率、反应时和错误类型为分析指标,两组儿童在发展年龄上进行匹配。 【结果】 1)孤独症组儿童识别混合面部表情的平均正确率小于正常对照组〔(58.0±15.6)%和(78.4±13.5)%,t=5.4,P=0.000〕,平均反应时长于正常对照组[(9 948.3±3 116.2)ms 和(5 617.0±1 362.9)ms,t=4.7,P=0.000]。2)孤独症组儿童区分面孔性别的平均正确率小于正常对照组[眼部为(76.7 ±11.5)%和(86.6±10.9)%,嘴部为(66.2 ±12.8)%和(73.1 ±10.7)%],平均反应时长于正常对照组[眼部为(4 138.7±542.0)ms和(2 721.9±636.6)ms,嘴部为(3 807.8±710.1)ms 和(2 836.5±619.9)ms]。 【结论】 孤独症组儿童在做关于面部表情的判断时更依赖于面孔的下半部分信息;他们可以使用来自眼部的信息来加工面孔的性别信息,而与正常对照组相比他们没有显示出有使用嘴部信息来处理面孔性别信息的优势。

佳木斯市大气PM10对呼吸系统疾病日人院人数的影响

目的 探讨2010-2014年佳木斯市大气PM10对城区居民呼吸系统疾病日入院人数的影响.方法 采用1∶3配比的时间分层病例交叉研究,控制气象等因素的影响,以条件logistic回归分析佳木斯市2010年1月1日-2014年12月31日大气PM10浓度与呼吸系统疾病日入院人数的关系,并按性别(男、女)、年龄(＜15岁、15～65岁、＞65岁)和疾病类型[肺炎、慢性阻塞性肺疾病(COPD)和支气管肺炎],对大气污染物的健康效应进行分层分析.结果 研究期间佳木斯市大气PM10的日均浓度及年均浓度均低于国家二级标准.大气PM10日均浓度与SO2、NO2、日均气压呈正相关,与日均温度呈负相关,差异均有统计学意义(P＜O.01).单污染物模型显示,研究期间大气PM10浓度每升高10μg/m3,与肺炎、COPD日入院人数的OR值分别在滞后4、3d达到最高,相应的OR值(95％CI)分别为1.021(1.002～1.041),1.022(1.004～1.040),均有统计学意义(P＜0.05);在控制气温、相对湿度、气压的影响后,多污染物模型显示,大气PM10浓度每升高10 μg/m3,仍会增加肺炎、COPD日入院人数,均有统计学意义(P＜0.05).性别分层结果显示,大气PM10浓度每升高10 μg/m3,可引起男性肺炎患者及男、女性COPD患者日入院人数增加,差异均有统计学意义(P＜0.05);年龄分层结果显示,大气PM10浓度每升高10μg/m3,可引起＜15岁、15～65岁、＞65岁肺炎、COPD、支气管肺炎患者日入院人数增加,差异均有统计学意义(P＜0.05).结论 佳木斯市呼吸系统常见疾病的日入院人数增加可能与该市大气PM10短期低浓度暴露有关联.
