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.     

小儿急性偏瘫综合征18例临床分析

目的:探讨小儿急性偏瘫综合征(AHS)的病因，临床特征和治疗方法。方法:对18例小儿AHS的临床资料进行回顾性分析。结果:小儿AHS患者小于3岁者占61．1％，多因感染(33．3％)、脑外伤(22.2％)引起，治疗后患儿语言障碍恢复较快，惊厥严重者偏瘫恢复慢。结论:小儿AHS以婴幼儿多见，病因主要是感染、脑外伤等，临床综合治疗效果良好。及早控制惊厥，对减少惊厥性脑损伤的发生，具有重要意义。     

宫颈妊娠1例报告

宫颈妊娠是罕见的异位妊娠,现报告1例如下。患者,27岁,停经14周,因下腹阵发性隐痛,并触及包块,不觉胎动来院就诊。经B超探查提示为中期妊娠,活胎、宫颈口内见胎盘。因要求引产,于1986年1月15日住院。1984年曾作人工流产一次,1985年2月曾孕足月剖宫产,现存一女婴。查宫底达耻骨上4横指,胎位不清,胎心140次/分。入院后曾     

生殖免疫研究的进展

生殖免疫学是研究免疫与生殖现象关系的学科。在进入阴道的精子到输卵管同卵管细胞融合,形成受精卵,再回到子宫,着床在子宫内膜,经分化、发育直至分娩的过程中,母体实际遇到很多非自身抗原。诸如精子和精浆抗原、胎儿和胎盘等器官的特异性分化抗原和来自父亲方面的同种抗原等等。对这些抗原,母体所产生的免疫应答,有时起维持和促进妊娠的作用;而有时则起障碍作用而成为不孕和流产的原因。偶而人体也可对睾丸或卵巢等自身抗原产生免疫应答,而成为男性不育和女性不孕症的原因。因而,生殖免疫学涉及的研究领域是多方面的。本文拟就最近     

丙型肝炎病毒与其他病毒的重叠感染

1.HCV 与其他病毒重叠感染的流行病学这里包括 HCV 与其他型肝炎病毒的重叠感染和 HCV 与肝炎病毒以外的病毒的重叠感染。多数报告证实,急性甲型肝炎、乙型肝炎患者中,HCV 抗体的阳转例非常少。在 HCV 携带者中存在 HAV、HBV 急性感染的可能,而在HBV 携带者中也存在 HCV 急性感染的可能性。在暴发型甲型或乙型肝炎中也检出了 HCV 抗

身体的保护屏障——皮肤

皮肤的生理作用有: 1、保护作用。 2、知觉作用。 3、体温调节作用。 4、呼吸作用。人的皮肤看不出有呼吸的感觉,但其实与肺的呼吸相比较,大约有1%的呼吸作用,其表现是水蒸汽由皮肤表面蒸发或皮肤组织内摄取氧而排泄二氧化碳之过程。     

吃药您喝足水了吗
