基于加权秩和比法评价广东省公共卫生资源配置

目的 评价2019年广东省不同地市（除中山市）的公共卫生资源配置状况。方法 从《2019年广东省卫生健康统计年鉴》中选取专业公共卫生机构数、专业公共卫生机构床位数、专业公共卫生机构执业(助理) 医师数、专业公共卫生机构注册护士数和每万人口公共卫生人数五个评价指标,利用加权秩和比法综合评价广东省不同地市的公共卫生资源配置差异。结果 WRSR与Probit的回归方程为[AKY^5]=0.250Probit-0.745（F=362.461,P<0.05,R=0.980）;将不同地市公共卫生资源配置分为四档,肇庆市、广州市、佛山市、深圳市四市公共卫生资源配置处于较高水平,则汕尾市、潮州市则较为落后。结论 广东省公共卫生资源整体上逐年提升,但每万人口公共卫生人数与目标相比还具有差距;不同地区间公共卫生资源配置差异大,人均获得资源不均衡。     

Changes in patterns of left ventricular hypertrophy after aortic valve replacement for aortic stenosis and regurgitation with St. Jude Medical cardiac valves

In this study, we analyzed the extent and pattern of regression of left ventricular (LV) hypertrophy after aortic valve replacement in patients with aortic stenosis (AS) and compared the results with those of another group of patients with aortic regurgitation (AR). Seventy patients who underwent isolated aortic valve replacement were divided into 2 groups. Group 1 was comprised of 29 patients who underwent aortic valve replacement for aortic stenosis, and Group 2 of 41 patients who underwent aortic valve replacement for aortic regurgitation. A third group of 10 healthy subjects served as a healthy control group. Echocardiographic studies were done before the operation and 5 years postoperatively. At follow-up, a significant reduction in the left ventricular mass was found in both groups, but it remained significantly greater than in the healthy control group. The ratio of LV wall thickness to radius (th/r) in Group 1 decreased significantly, and at follow-up it was within the normal value. In Group 2, the th/r ratio increased, and at follow-up it was within the normal value. After aortic valve replacement, the wall thickness remained significantly greater than normal for patients with AS, and the chamber radius remained significantly greater than normal for patients with AR. For these reasons, LV hypertrophy still existed in both groups at postoperative follow-up. The actuarial survival rate was 85.3% at 16 years for Group 1 and 83.4% at 18 years for Group 2. There was no significant difference in the long-term survival rates between the 2 groups. Actuarial freedom from valve-related events was 91.9% at 16 years for Group 1 and 82% at 18 years for Group 2. There was no significant difference in the valve-related event free curves between groups. After 5 years of follow-up, th/r reached normal for both groups, indicating remodeling of the LV geometry after aortic valve replacement.     

医疗保险风险因素的相对风险度分析

目的 :探讨医疗保险风险因素的相对风险度及其分析方法。方法 :借鉴流行病学研究方法 ,用 logistic回归模型产生比值比 (OR)来刻画风险因素与医疗保险赔付 (损失 )之间的定量关系。结果 :实例拟合单因素及多元 logistic回归模型 ,得到各风险因素的 OR值并能合理地解释。结论 :相对风险度分析为医疗保险风险控制提供了新的分析思路和定量依据     

An Analysis for the Comprehensive Evaluation of Health Resources Allocation in Shenzhen

INCREASING HEALTH COSTS are a dilemmafaced by the health administration. In order to en-hance the productivity, we must invest in healthservices. Meanwhile, limited health resources shouldbe properly allocated to obtain maximal socioeco-nomic benefits at lowest input. Thus, it is especiallyimportant to comprehensively assess the allocationof health resources from the perspectives of theInput and Output. The comprehensive evaluation ofhealth resources is a topic of interest for multi-objective assessment, wh...     

阻力指数比率对梗阻性积水肾功能的评估

目的:探讨多普勒超声肾内阻力指数比率在诊断单侧梗阻性肾积水及对积水肾功能的可复性评估的临床应用价值。方法:用多普勒超声检测53例单侧梗阻性肾积水患者主肾动脉、肾段动脉及叶间动脉的多普勒频谱,检测指标为收缩期最大峰值流速(Vmax)、舒张末最低流速(Vmin)、阻力指数(RI)和阻力指数比率(RIR),并且进行术前、术后3月和6月的动态观察,同时静脉尿路造影(IVU)对比,正常对照组36例。结果:53例单侧梗阻性肾积水患者中,中度肾积水和重度肾积水的RI及RIR均升高,但以RIR更为显著(P<0.01),轻度肾积水RIR升高(P<0.05)比RI(P>0.05)显著;梗阻解除术后动态观察RIR比RI恢复更为明显、迅速。结论:肾内阻力指数比率(RIR)为单侧梗阻性肾积水的诊断及积水肾功能的可复性评估提供了一种简便有效的方法。
