Correlates of lifetime suicide attempts among individuals with affective disorders in a Chinese rural community.

The aim of this study was to compare the demographic and clinical characteristics of individuals with affective disorders who had attempted suicide at some time in their lives and those who had not made a suicide attempt. In a Chinese rural community, individuals with suicide attempt (N = 30) and those without suicide attempt (N = 166) were assessed with Present State Examination (PSE). Attempters had a significantly higher level of family economic status, higher rate of lifetime depressed mood and hopelessness, and delusions than nonattempters. The logistic regression models also indicated that depressed mood and hopelessness were the most important predictors of suicide attempts. No significant difference in treatment condition was found between attempters and non-attempters. Early identification and interventions focusing on reducing depressed mood, hopelessness, and controlling psychotic symptoms may be helpful in reducing the risk of suicide attempts among individuals with affective disorders residing in the community.     

两出口的医院网络用户管理解决方案

目的：由于办公需要，将以前走电信出口的图书馆、医疗二系及研究生处的用户改道为走科研教育网出口，和华中科技大学校总部相连，并在不改变原来管理模式下同时管理两出口的用户信息。方法：通过配置流分类，规定重定向行为以及配置策略路由进行实现。结果：将认证流和数据流分开，成功实现了医院内部两出口的需求。结论：利用原有设备的流分类和重定向功能．既可解决两出口的内部需求，也能在不增加设备的情况下对用户信息进行管理，为医院节省了开支。     

创伤性肾动脉下腔静脉瘘封堵术1例

患者女,59岁,因“胸闷伴中上腹不适2月余”入院。患者进食后腹部不适加重,休息后可缓解。晨起脸部浮肿,活动后可消退,不伴有双下肢水肿。27年前因右肾结石行右肾切除术。查体:心浊音界增大,中上腹可闻及收缩期杂音。MRA显示右肾动脉与下腔静脉异常交通,右肾动脉远端瘤样扩张,下     

输尿管上段结石的微创手术治疗

目的：探讨输尿管上段结石的治疗方法。方法：回顾性分析输尿管镜下气压弹道碎石(URSL），后腹腔镜输尿管切开取石(RLU)、经皮肾穿刺取石(PCNL)治疗输尿管上段结石患者的临床资料。其中URSL组25例，RLU组20例。PCNL组9例。结果：URSL组碎石成功18例；7例不成功，其中3例改为开放手术，1例改为后腹腔镜取石。2例行ESWL术，1例仅留置双J管。术后1个月拔管后自行排出。2例并发输尿管穿孔。RLU组取石成功18例，2例滑入肾内，经配合输尿管镜和腹腔镜直视下经皮肾穿刺取石成功，术后15例有伤口漏尿。PCNL组成功9例，无并发症。结论：USRL创伤小。术后恢复快。是治疗输尿管上段结石的较为满意的治疗方法。PCNL创伤小，取石成功率高，在结石靠近肾盂、儿童输尿管上段结石并同侧肾结石和结石以下输尿管狭窄时应优先考虑。但技术难度较大。RLU可作为URSL不成功后的辅助治疗方法。     

骨性AngleⅡ类2分类错正畸治疗前后硬组织的变化

目的:采用直丝弓矫治器矫治成年患者骨性AngleⅡ类2分类错牙合,以研究正畸治疗前后牙、颌硬组织变化,评价正畸矫治效果。方法:本文选择了8例AngleⅡ类2分类错牙合成年患者,男3例,女5例,年龄19~27岁,平均23.6岁。拔除双侧上颌第一双尖牙,运用直丝弓矫治器进行治疗,拍摄治疗前后X线头颅定位侧位片,进行治疗前后的X线头影测量研究。结果:治疗后SNA角减小,ANB角减小,U1-SN角增大,L1-MP角增大,U1-L1角减小。上颌切牙牙根及上颌基骨明显腭向移动,减小了上颌骨突度;下颌切牙牙冠明显唇向倾斜,代偿了下颌骨后缩。结论:骨性AngleⅡ类2分类错牙合患者经过上颌拔牙矫治后,面形有所改善,取得了理想的矫治效果。     

冠状CT扫描对颅脑疾患的诊断意义

作者通过对30例颅脑疾患冠状CT扫描资料进行研究,提出在一定情况下,在横断CT扫描的基础上,加用冠状CT扫描或冠矢重建图象,对病变的精确定位、病变的起源和发展方向以及病变与周围结构的关系等很有裨益。
