简介：目的评估抗高血压治疗中血压值与卒中的发生是否存在J型曲线。方法回顾性分析2009年1月-2013年10月于门诊或住院接受治疗的2059例高血压患者,采用限制性立方样条（restrictedcubicspline,RCS）拟合Cox回归模型来评估不同的血压截点与卒中的关系,用Kaplan-Meier法评估随访期间卒中的发生率,Cox比例风险模型分析影响卒中的独立危险因素。结果总体患者1、3、5年累积卒中发生率分别为2.5%、8.8%和16.6%。经RCS拟合Cox模型评估,发现血压值与是否发生卒中呈非线性关系,对于收缩压（systolicbloodpressure,SBP）〈110mmHg或〉150mmHg的患者,以及舒张压（diastolicbloodpressure,DBP）〈60mmHg或〉90mmHg的患者,卒中的发生风险增加。经Cox风险比例模型多因素分析,吸烟史（HR2.32,95%CI1.36-3.13,P=0.009）、糖尿病（HR2.07,95%CI1.18-3.05,P=0.011）、心房颤动（HR1.89,95%CI1.16-2.98,P=0.014）、SBP〈110mmHg（HR1.62,95%CI1.11-2.24,P=0.032）或〉150mmHg（HR1.79,95%CI1.21-2.72,P=0.013）和颈动脉狭窄（HR2.47,95%CI1.37-4.18,P=0.008）是卒中的独立危险因素。结论抗高血压治疗中,存在血压值与卒中的J型曲线现象;SBP〈110mmHg或〉150mmHg的患者,卒中的发生风险增加。

简介：Labbe＇s静脉是连接大脑中浅静脉和横窦之间的吻合静脉,又称下吻合静脉,在脑的静脉回流中起着重要的作用[1,2]。重型颅脑损伤合并Labbe＇s静脉损伤时常可导致严重后果,由于颅脑损伤的复杂性,如同时合并Labbe＇s静脉损伤使治疗更为困难。本文通过对榆林市北方医院自2006年3月至2012年2月采用手术治疗的36例重型颅脑损伤同时合并Labbe＇s静脉损伤病例分析，探讨最佳的治疗方案，现报告如下。
