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.     

芬太尼复合丙泊酚与瑞芬太尼复合丙泊酚用于无痛人流术的麻醉效果观察

目的观察芬太尼复合丙泊酚与瑞芬太尼复合丙泊酚用于无痛人流术的麻醉效果和安全性。方法将160例行无痛人流术的早孕妇女随机分为两组,即芬太尼复合丙泊酚组（A组,n=80）和瑞芬太尼复合丙泊酚组（B组,n=80）。对两组患者的麻醉镇痛效果进行评级,观察并记录两组患者麻醉前、手术中、手术结束时的血压（BP）、心率（HR）、呼吸频率（RR）、血氧饱和度（SpO2）变化,以及丙泊酚用量、清醒时间、离院时间和术后腹痛情况。结果两组患者麻醉前、手术中、手术结束时的BP、HR、RR、SPO2均有变化,但组间比较无统计学意义（P〉0.05）;两组的术中镇痛效果均满意,组间比较差异无统计学意义（P〉0.05）;但术后镇痛效果比较A组优于B组（P〈0.01）;两组丙泊酚用量、术毕清醒及离院时间比较差异无统计学意义（P〉0.05）。结论芬太尼复合丙泊酚与瑞芬太尼复合丙泊酚应用于无痛人流术麻醉,两种方法均安全可靠,镇痛效果满意,但芬太尼复合丙泊酚麻醉的术后镇痛效果更好。

克山病发病危险因素的病例对照研究

目的探讨克山病发病的危险因素，为制定克山病防治措施提供依据。方法在黑龙江省克山病病区选取41例克山病患者作为病例组．另选134例健康人作为对照组，采用氢化物发生原子荧光光度法检测病例组和对照组全血含硒量．采用5，5’-二硫双-2-硝基苯甲酸（DTNB）分光光度法检测全血谷胱苷肽过氧化物酶（GSH—Px）活力：同时对病例组和对照组进行克山病危险因素的问卷调查，先用单因素卡方检验筛选有意义变量，再引入多因素Logistic回归模型进行综合分析。结果全血含硒量病例组[（34．86±13.14）μg／L]明显低于时照组[（40．97±13．62）μg／L]，两组比较差异有统计学意义（t=2．254，P〈0．05）；GSH—Px活力病例组[（104．10±34．19）U／L]明显低于对照组[（118．57±25．49）U／L]．两组比较差异有统计学意义（t=2．312，P〈0.05）。在问卷调查中，经卡方检验和多因素Logistic回归分析，发现年人均收入水平[比值比（OR）=2.570]、肉类（OR=0．284）和蛋类（OR=0．347）的摄入次数与克山病发生有统计学联系，结论在克山病病区人群中，机体内全血含硒量和GSH—Px活力的下降、年人均收入水平低很可能是克山病发病的危险因素，动物性蛋白摄入的增加可能对克山病的发病起到保护作用：     

Holter对老年无症状心肌缺血的诊断价值

目的 评价12导动态心电图(Holter)对老年无症状性心肌缺血的诊断价值.方法 对确诊的345例老年冠心病患者,在同期内(间隔小于3天)接受12导Holter及普通心电图(ECG)检查,将两种检查结果进行对比分析.结果 12导Holter和ECG对无症状性心肌缺血(SMI)的检出率分别是75.5%和7.7%,二者之间差异具有显著性(P＜0.05).结论 12导Holter可以较早地发现SMI,有助于指导临床治疗,降低心脏猝死.
