Objective:To evaluate the efficacy and safety of the treatment of traumatic hemothorax by closed pleural drainage using a central venous catheter(CVC),compared with using a conventional chest ***:A prospective controlled study with the Ethics committee approval was undertaken.A total of 407 patients with traumatic hemothorax were involved and they were randomly assigned to undergo closed pleural drainage with CVCs(n={1.4) or conventional chest tubes(n=1.3..The Seldinger technique was used for drainage by CVC,and the conventional technique for drainage by chest *** the residual volume of the hemothorax was less than {1.0 ml after the daily volume of drainage decreased to below 1.0 ml for two consecutive days,the treatment was considered *** correlative data of efficacy and safety between the two groups were analyzed using t or chi-squared tests with SPSS 1.2}0.A P value of less than 0.05 was taken as indicating statistical ***:Compared with the chest tube group,the operation time,fraction of analgesic treatment,time of surgical wound healing,and infection rate of surgical wounds were significantly decreased(P0.05),or in the mean catheter/tube indwelling time and mean medical costs of patients treated successfully(P>0.05).Conclusions:Management of medium or large traumatic hemothoraxes by closed thoracic drainage using CVC is minimally invasive and as effective as using a conventional large-bore chest *** complications can be prevented and it has the potential to replace the large-bore chest tube.

Human rights of women are an inalienable, integral and indivisible part of universal human rights, as well as a major reflection of social civilization and social harmony. Human society is a whole consisting of men and women. The world will inevitably be a disharmonious one if women, who make up half of the total population, cannot enjoy equal human fights. Therefore, gender equality is an essential part of a harmonious society. Strengthening protection of human fights of women is absolutely necessary for building a harmonious world and the development of human fights of women will inevitably promote the building of a harmonious world.

当代资本主义的新变化主要表现为资本占有、经济运行、阶级关系、分配形式四个方面。引起这些变化的原因是 :资本主义生产关系尚有对生产力的适应力 ;工人阶级的不懈斗争改变了资本主义进程 ;社会主义的成就对资本主义产生了深刻的影响。但是 ,资本主义的本质没有改变 ,资本主义基本矛盾没有消除 ,社会主义代替资本主义的总趋势没有改变。资本主义的新变化借鉴了社会主义的成就 ,增添了社会主义的因素 ,这是社会主义必然性的预示。
