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.     

兔肢体爆炸伤合并海水浸泡后在不同复温速率及维持浅低体温下机体炎症反应的特征

Objective To investigate effects of different rewarming rates and maintenance of light hypothermia on inflammatory response in rabbits after limb blast injury, coupled with seawater immersion. Methods First, the model of limb blast injury coupled with seawater immersion was reproduced [the animals were immersed to low body temperature of (31.0±0.5℃)]. Then, 24 adult rabbits were randomly divided into group Ⅰ [the rapid rewarming group, n=6, rewarmed to (38±0.5)℃ at a rate of (8.94±0.93)℃/h], group Ⅱ [the slow rewarming group, n=6, rewarmed to (38±0.5)℃ at a rate of (3.88±0.22)℃/h], group Ⅲ [another slow rewarming group, n=6, rewarmed to (38±0.5)℃ at a rate of (2.18±0.12)℃/h], and the H group [the hypothermia group, n =6, rewarmed to (34 - 35)℃ at a rate of (4.49±0.66)℃/h and kept at that temperature till termination of the experiment]. Regulation of ambient temperature and warm transfusion were used to restore body temperature to target levels and maintained there for 6 hours. Blood samples were taken at 5 different times, I.e. Pre-injury time(T0), post-immersion time (T1), the time when rewarming started (T2), 3 h after rewarming (T3), and 6 h after rewarming (T4). Tissue samples from heart, liver, intestinum, lung and kidney were also collected. Levels of TNF-α (tumor necrosis factor-α), IL-1β (interleukin-1β) and IL-6 (interleukin-6) in plasma and MPO (myeloperoxidase) in homogenate were detected. Results Following rewarming, TNF-α, IL-1β, IL-6 concentrations in the plasma of the animals in group Ⅰ and group H were significantly higher when compared with those of the animals in group Ⅱ and group Ⅲ (P<0.05, P<0.01), and MPO activity in homogenate was significantly higher when compared with that of the animals in group Ⅱ and group Ⅲ(P<0.01, P<0.05), and no statistical difference could be seen between group Ⅱ and Ⅲ (P>0.05). Conclusions Rapid rewarming and maintenance of light hypothermia could obviously elevate TNF-α, IL-1β, IL-6 concentrations in plasma and MPO activity in homogenate, following limb blast injury coupled with hypothermia induced by seawater immersion, while slow rewarming (with a rewarming rate of 2-4℃/h) could significantly inhibit TNF-α, IL-1β, IL-6 levels and PMN activity.     

The Application of Topical Anesthesia Combined with Subconjunctival Anesthesia for Glaucoma Surgery

Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5％ Alcaine eye drops combined with subconjunctival anesthesia with 2％ Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes (85.2％) were painless (Grade Ⅰ), 50 eyes (14.0％) were slight painful (Grade Ⅱ), and 3 eyes (0.8％) were more painful (Grade Ⅲ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow vi

军队在职干部腰身指数与心血管危险因素相关性探讨

目的 研究用腰身指数（腰围/身高比值WHtR）作为腹型肥胖指标探讨与心血管危险因素的相关性。方法 对2005年3月～2006年12月入住广州疗养院的军队在职干部共495人进行身高、体重、腰围、血压、心率、生化等检测,并进行统计学分析。结果 腰身指数异常组的年龄、体重、SBP、DBP、FBS、TC、TG以及尿酸均显著高于腰身指数正常组,HDL-C的结果则相反（P〈0.01～P〈0.001）;同时腰身指数与年龄、体重、SBP、DBP、FBS、TC、TG呈显著正相关,与HDL-C呈显著负相关（P〈0.05～P〈0.001）。结论 腰身指数可作为有效的腹型肥胖参考指标,腰身指数异常者其心血管危险因素水平比正常者高,及时控制腰身指数可以有效改善人群的健康状况。
