危重症患者的APACHEⅡ评分与中医辨证相关性研究

目的：通过比较不同中医证型的ICU危重症患者的APACHEⅡ评分，同时对比两组死亡率，评价中医辨证在预后判断中的临床意义。方法：对纳入研究的85例ICU危重症患者于入ICU及出ICU时分别进行中医辨证，分为阳类证和阴类证两型，对所有病人进行APACHEⅡ评分，比较两型病人在进入ICU及出ICU时的APACHEⅡ分值，并与死亡率比较。结果：初始为阴类证的患者在入ICU及出ICU时的APACHEⅡ评分显著高于初始为阳类证的患者（P=0．0001及F〈0．05），死亡率亦显著高于阳类证患者（P=0．0369）：治疗后由阳类证转为阴类证患者APACHEⅡ评分较维持阳类证者增高（P=0．0161），而阴类证转为阳类证的患者APACHEⅡ分值较维持阴类证者减低（P=0．0424）。结论：中医证型对危重症的病情程度及预后判断有较好的预测价值，阴类证患者的预后较阳类证患者差，证型转换可能引起预后改变。     

Cause-specific and total mortality in the Canterbury (New Zealand) insulin-treated Diabetic Registry population: a 15-year follow-up study.

AIMS: To establish all-cause and cause-specific death rates, and risk factors for mortality in insulin-treated diabetic individuals living in the province of Canterbury, New Zealand. METHODS: Insulin-treated diabetic subjects (n = 995) on the Canterbury Diabetes Registry were followed up over 15 years and vital status determined. Death rates were standardized and hazard regression was used to model the effects of demographic covariates on relative survival time. RESULTS: There were 419 deaths in 11 226.3 person-years of follow-up with a standardized mortality ratio (SMR) of 2.0 (95% confidence interval (CI) 1.8-2.2). Relative mortality was greatest for the group aged 0-29 years (SMR 3.0 (95% CI 2.4-3.7)). After controlling for diabetes duration and gender, a 10-year increment in age of onset was associated with a 33% decrease in relative hazard (95% CI 29-36%), indicating that excess mortality due to diabetes declines with rising age of onset. After controlling for age of onset and gender, each 10-year increment in duration of diabetes is associated with a 26% decrease in relative hazard (95% CI 24-29%), indicating that with longer survival the mortality hazard approaches the general population hazard. Relative mortalities were increased for cardiovascular, renal and respiratory disease, but not malignancy. Relative mortality from acute metabolic complications was increased in the subgroup with age of onset of diabetes < 30 years and requiring insulin within 1 year of diagnosis. CONCLUSIONS: Mortality rates are high for insulin-treated diabetic individuals relative to the general population.

发育期大鼠高热惊厥前后海马γ-氨基丁酸B受体亚基表达的变化

目的：研究高热惊厥(febrile seizures，FS)对发育期大鼠脑内γ-氨基丁酸(γ-aminobutyric acid，GABA)B受体亚基GABABR1与GABARR2蛋白表达的影响。方法：采用热水浴诱导大鼠高热惊厥模型。隔日诱导惊厥1次，共诱导10次，末次惊厥后24h处死大鼠。发育期大鼠随机分为3组：对照组(n＝24)，1次高热处理组(n＝28)，10次高热处理组(n＝40)。高热处理组根据是否出现惊厥再分为1次高热惊厥组(FS1，n＝16)与1次高热未惊厥组(F1，n＝12)，10次高热惊厥组(FS10，n＝15)与10次高热未惊厥组(F10，n＝13)。采用免疫组化方法观察不同次数高热惊厥大鼠脑内GABABR1与GABABR2蛋白表达的变化。结果：FS10大鼠海马齿状回、CAl-CA3区GABABRl和GABABR2蛋白表达明显低于F10、F1、FSl和对照组；F10大鼠上述脑区GABABRl和GABABR2蛋白表达低于F1、FS1和对照组；F1及FS1大鼠与对照组相比差异无显著性；海马各区GABABR1与GABABR2表达的改变大部分平行，但10次高热惊厥后GABABR2在CA1—CA3区下降更明显，而GABABR1在齿状回下降更明显。结论：反复高热惊厥及反复高热均可使发育期大鼠脑内GABABR亚基蛋白表达降低，高热惊厥的影响较单纯高热更为明显，提示GABABR亚单位与发育期大鼠高热惊厥及其脑损伤密切相关。GABABR1与GABABR2改变的不平行可能与受体亚单位组合的可塑性改变有关，这种改变可能导致抑制功能的改变。     

Facial reanimation after acoustic neuroma excision: the patient's perspective

Facial reanimation after acoustic neuroma excision is currently accomplished using a variety of surgical techniques. A multi-institutional survey of patient perceptions of facial reanimation success was accomplished by mailing a questionnaire to 809 randomly selected members of the Acoustic Neuroma Association. Four hundred sixty patients who underwent 296 reanimation procedures responded. Facial to hypoglossal nerve anastomosis, tarsorrhaphy, and upper eyelid implants were most frequently performed. The patient's estimations of initial deficit, spontaneous recovery, and overall satisfaction with the reanimation procedures are discussed.
