简介:目的探讨自然人群中血糖、体重指数(BMI)、腰臀比(WHR)的水平对血压的影响及作用的大小.方法应用1998年广东省糖尿病流行病学调查资料,采用分层整群抽样方法,调查对象年龄在20~74岁.血糖值为早晨空腹口服75g葡萄糖2h后的血糖值.糖尿病及糖耐量低减(IGT)的诊断标准采用1999年WHO糖尿病诊断标准.高血压诊断标准采用1999年中国高血压防治指南.结果共调查11377人,其中男性5183人,女性6194人,平均年龄43岁,平均收缩压、舒张压、血糖、体重指数、腰臀比分别为117mmHg、74mmHg、104mg/dL、22kg/m2和0.84.糖尿病者高血压患病率明显高于血糖正常者,为45.3%比14.4%,糖耐量低减者高血压患病率明显高于糖耐量正常者,为32.2%比14.5%,肥胖者高血压患病率明显高于非肥胖者,为21.5%比10.4%.多重线性回归模型分析显示,年龄、血糖、体重指数、腰臀比对男女性收缩压和舒张压有显著影响.结论广东省自然人群的分析结果显示,血糖、体重指数和腰臀比是影响血压的重要因素,在控制我省高血压患病率不断增加的同时,尚须要注意控制血糖、体重指数和腰臀比的升高.
简介:目的探讨甲型H1N1流感患者心脏损害的特点。方法回顾性研究分析2009年7月至2010年1月期间确诊为甲型H1N1流感患者172例的临床资料,所有患者根据病情分为轻症组,重症组,危重症组,并收集非甲型H1N1流感患者21例作为对照。大部分患者接受分子生物学检测磷酸肌酸激酶,磷酸肌酸激酶同工酶,高敏C反应蛋白,并接受胸部X线摄片检查,计算心胸比。结果甲型H1N1流感多发生于青壮年患者,轻症患者较重症患者更年轻(P<0.05)。在危重症患者中,磷酸肌酸激酶,磷酸肌酸激酶同工酶,高敏C反应蛋白和心胸比均较其他组高(P<0.05或P<0.01)。1例死于心肌损害。结论与既往研究相符,2009甲型H1N1流感可以导致心肌损害,特别是在危重症患者中心肌损害较显著,从而将导致心脏扩大等损害,导致死亡率升高。
简介:目的探讨老年慢性心力衰竭(CHF)住院患者中合并糖尿病的比率,并比较其在不同年龄段的区别.方法回顾性分析近30年来我院确诊为CHF的住院并且出院时尚存活的患者704例,并对老年前期(45~59岁),老年期(60~74岁)和高龄期(≥75岁)3组患者的资料进行比较.结果≥60岁CHF患者中合并糖尿病者占20.3%(87/428);在3组的比率随年龄增高分别为6.2%,18.7%和23.4%(P<0.01);在两种病因所致的老年CHF患者中合并糖尿病的比率为27.5%,在3组中的比率随年龄的增加分别为11.4%,23.0%和38.5%;在两种以上多病因所致的CHF患者中上述比率为15.9%(49/309),3组的比率依次为9.5%,11.6%和42.9%.结论老年CHF住院非死亡患者随年龄的增长,合并糖尿病的比率明显增高;在多病因所致的CHF中此比率亦明显增高.

简介:摘要目的比较脊麻硬膜外联合麻醉(CSEA)用于剖宫产时使用等比重和重比重布比卡因对剖宫产患者麻醉起效时间、脊麻平面、运动阻滞程度、麻醉效果、并发症等方面的影响。方法选择ASAⅠ~Ⅱ级剖宫产妇100例,随机分成两组,每组50例,均采用CSEA麻醉,穿刺成功后蛛网膜下腔分别注入Ⅰ组等比重液,Ⅱ组注入重比重液,平卧位后,针刺法测定阻滞范围。麻醉期连续监测BP、HR、ECG和SPO2,观察并记录给药后麻醉起效时间、运动阻滞程度、脊麻平面、麻醉效果、并发症的发生率。结果麻醉起效时间、脊麻平面、运动阻滞程度两组间无显著差异,两组间麻醉效果、低血压、恶心呕吐、呼吸困难、术后头痛发生率无差异。结论CSEA用于剖宫产时,选择等比重和重比重布比卡因的脊麻效果、并发症相当。但等比重液可能更具优点。等比重布比卡因CSEA用于剖宫产尤其是胎儿宫内窘迫等急症剖宫产,用药单一,操作相对简单。局麻药液在脑脊液中的扩散受患者体位影响较小,无需头高足低体位,无需担心硬膜外置管不顺或其他原因而导致一侧腰麻效果不佳。

简介:摘要目的研究反复呼吸道感染(RRI)患儿细胞及体液免疫功能及血清sIL—2R水平监测情况。方法回顾分析2015年1月至2016年1月期间在我院治疗的82例反复呼吸道感染患儿临床资料,检测患者血清免疫球蛋白IgA、IgG、IgM水平、总T淋巴细胞、T淋巴细胞亚群变化(CD4+、CD8+、CD4+/CD8+、)。结果RRI患儿总T淋巴细胞、CD4+、CD4+/CD8+明显低于正常患儿,CD8+、sIL-2R水平明显高于正常患儿,差异有统计学意义(P<0.05);血清免疫球蛋白IgA、IgG水平明显低于正常患儿,差异有统计学意义(P<0.05)。结论反复呼吸道感染患儿细胞及体液免疫功能均明显发生紊乱,临床检测胞及体液免疫功能对临床治疗具有一定的指导意义。
