20例腔隙性脑梗塞临床分析

腔隙性脑梗塞是指发生在大脑半球深部白质和脑干，直径约2—15mm的缺血性梗塞。梗塞灶呈圆形或卵圆形，多发于基底节和内囊区，因为这些部位供血动脉大多远离动脉主干，行走弯曲，易要缺血影响。1、临床资料1．1、一般情况本组20例，男14例，女6例。年龄最小50岁，最大74岁，平均年龄62岁。其中既往有高血压病史者13例，糖尿病病史者4例，发作者曾出现短暂性脑缺血发作（TIA）者3例。1．2、临床表现根据本组病例临床表现分以下几种类型：1．2．1、纯感觉障碍型。表现为一侧面部及肢体麻木，但无肢体力弱、偏盲、失语等症状。肢体麻木呈持…     

The outbreak pattern of the SARS cases in Asia

The severe acute respiratory syndrome (SARS) caused tremendous damage to many Asia countries, especially China. The transmission process and outbreak pattern of SARS is still not well understood. This study aims to find a simple model to describe the outbreak pattern of SARS cases by using SARS case data commonly released by governments. The outbreak pattern of cumulative SARS cases is expected to be a logistic type because the infection will be slowed down due to the increasing control effort by people and/or due to depletion of susceptible individuals. The increase rate of SARS cases is expected to decrease with the cumulative SARS cases, as described by the traditional logistical model, which is widely used in population dynamic studies. The instantaneous rate of increases were significantly and negatively correlated with the cumulative SARS cases in mainland of China (including Beijing, Hebei, Tianjin, Shanxi,the Autonomous Region of Inner Mongolia) and Singapore. The basic reproduction number R0 in Asia ranged from 2.0 to 5.6 (except for Taiwan, China). The R0 of Hebei and Tianjin were much higher than that of Singapore, Hongkong, Beijing, Shanxi, Inner Mongolia, indicating SARS virus might have originated differently or new mutations occurred during transmission. We demonstrated that the outbreaks of SARS in many regions of Asia were wall described by the logistic model, and the control measures implemented by governments are effective. The maximum instantaneous rate of increase, basic reproductive number, and maximum cumulative SARS cases were also calculated by using the logistic model.
