小中风的前兆

正想象一下这两种情况,当您准备写一张纸条时,感觉自己手中的笔是在湿湿的混凝土上移动。或者是您的视力突然不正常了——就好像一块黑色的窗帘盖在您的一只眼睛上了。如果这些奇怪的症状只持续几分钟,你可能只是按按自己的双手或是揉揉自己的双眼,认为这只是一次很普通的肌肉抽搐或仅仅是因为疲劳。神经内科专家称,千万不     

“无声”心脏病发作的危险

<正>多达一半的心脏病发作未能被发现,而他们的长期后果可能是严重的。大多数人在没有觉察的情况下就发作了心脏病。这种心脏病发作通常被称作"无声"心脏病发作,但我们用一个更准确的术语称之为"未被识别"的心脏病发作。专家指出,有些人确实出现了症状,所以从这种意义上来说,他们的心脏病发作并不是无声的。他们只是没有意识到这些不适感源自心脏。有两个最常见的患者感到不适的感觉是消化不良和肌肉疼痛,但其真正的原因是心脏的血流量变

遗传性中性粒细胞髓过氧化物酶缺乏

人的中性粒细胞（PMN），用罗氏染色（Romanowsky stain）在光学显微镜下观察，可见胞浆中含有两种颗粒：嗜天青颗粒（又称初级颗粒）和特异性颗粒（又称次级颗粒）。嗜天青颗粒为粗大的紫红色，在原始粒细胞阶段很少或见不到，至早幼阶段含量最丰富。随着细胞的成熟，酸性粘蛋白合成增加，并与嗜天青的碱性颗粒形成复合物，从而失去嗜天青的特性。故自中幼阶段以下，嗜天青颗粒已变得不明显，甚至已见不到，而让位于细小、不规则的特异性颗粒。然而，在电子显微镜下，即使成熟的PMN，嗜天青颗粒仍可见到。[第一段]     

胰腺假性囊肿的治疗：附35例报告

回顾分析35例胰腺假性囊肿患者的临床资料。非手术治疗6例，6例经皮导管引流，23例开腹手术治疗,疗效满意。提示:胰腺假性囊肿的治疗,应根据囊肿形成的时间、囊肿的大小、 囊肿的不同部位、患者能否耐受手术以及有无合并症等因素,采用不同的治疗方法。     

在腹腔镜下行髂内动脉结扎及置泵10例

目的 探讨腹腔镜髂内动脉结扎及置泵可行性。方法 对10例膀胱癌患者采用经腹腔镜行一侧髂内动脉结扎并植泵，对侧髂内动脉结扎，用于膀胱癌经尿道电切术后的序贯化疗。结果 1例改行开放髂内动脉置泵，9例手术成功。手术时间40～120min，平均65min。出血10～30mL，肠功能恢复6～12h，当日开始灌注化疗药物，术后3d下床活动。带泵2、3a。结论 在腹腔镜下行髂内动脉结扎及置泵具有创伤小、出血少、愈合快等优点，在泌尿外科有很宽广的发展前景。

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.
