天津市1989 ～ 1998 年伤害死亡状况分析

探明不同地区、不同时期、不同年龄的伤害类型和严重性 ,有助于政府及全社会对伤害的控制和预防。为此我们对天津市 1989～ 1998年的伤害死亡水平及其年龄分布特征进行分析。1.伤害总死亡状况及主要死因分析 :1989～ 1998年伤害一直是天津市居民主要死亡原因中的第五位 ,年平均死亡率为 31.2 8/ 10万 ,年均死亡人数为 2 75 7.3人 ,低于全国伤害死亡的平均水平[1] 。 10年资料的分析显示 ,除“意外的机械性窒息”从未列入过前十位死因外 ,其他死因均在不同年份中进入前十位。其中机动车交通事故、自杀、意外中毒这 3种死因始终位居前三位 ;“…

The relationship of variability of blood pressure with cardiac structure and functions in hypertension

ObjectiveTo study the relationship of variability of blood pressure with cardiac structure and functions in essential hypertension.Methods A hundred and ten patients suffered from essential hypertension were divided into two groups according whether having left ventricular hypertrophy. The characteristics of overload and variability of blood pressure in both groups were analysed and several indexes on cardiac structure and function were compared between two groups. Results Both groups showed significant differences in the mass of left ventricle (LVM), the mass index (LVMI) of left ventricle, the thickness of interventricular septum (IVS), posterior wall of left ventricle (LVPW) and relative wall thickness (RWT) except for hypertensive ages. The ratio of E/A in both groups was significantly decreased. The rate of SBP load (SBPLO) both at day and night, the level of SBP in 24 hours and reductive rate of SBP at night (nSBPrr), the variabilities of systolic blood pressure (SBPV) and mean arterial pressure (MAPV) as well as hypertensive vascular overload index (HTNVOI) in two groups were obviously different. Conclusions 1) In early stage, the diastolic cardiac function in essential hypertension was damaged. 2) The happeness of left ventricular hypertrophy in essential hypertension was not only associated with the degrees and types of vascular overload, the increased variabilities of systolic blood pressure and mean arterial pressure, reversely with the reductive rate of SBP at night as well, but feebly with hypertensive age. 3) As a low awareness, hypertensive age was unreliable in the recollection. 4) Age was also a risk factor of left ventricular hypertrophy in essential hypertension.
