锤造金属全冠由于其材料易得，工艺简单，经济方便，在临床工作中依然起着不可替代的作用。尤其在以下几种情况时：1)基层医院不具备烤瓷、铸造冠修复条件；2)牙折裂的固定修复治疗；3)牙体殆面大面积缺损经银汞或复合树脂充填后，由于剩余牙体轴壁过薄，其抗力严重不足，可能导致冠折；4)年轻恒磨牙由于其髓角较高，如果设计铸造冠，可能造成意外穿髓，病人难以忍受等等，以上均为锤造冠的适应证。牙体组织切割较少是锤造冠的一个很大优势，     

生姜凝胶贴剂的制备及其体外透皮吸收的研究

目的：制备生姜凝胶贴剂，研究不同促渗剂对生姜凝胶贴剂体外透皮性能的影响。方法：以卡波姆U10为基质主要成分制备生姜凝胶贴剂，用离体大鼠皮肤为透皮屏障，采用改进的Franz扩散池，通过体外渗透性实验对含有不同处方的生姜凝胶贴剂进行了透皮性能的研究。结果：生姜凝胶贴剂制备工艺简单，各类促渗剂对6-姜酚的经皮渗透有不同程度的促进作用，其中含4％氮酮的生姜凝胶贴剂具有良好的透皮性能。结论：生姜凝胶透皮贴剂具有临床应用价值，值得在临床上试验推广。     

病后调养莫过度

人在大病初愈之时,以谷、肉、果、菜等调补滋养,可谓天经地义。但如果调养失宜,往往事与愿违,反致疾病复发,症状加重,     

单腔起搏复律除颤器反复放电1例分析

患者女性，46岁，既往有甲亢病史5年，阵发性房颤间歇服用胺碘酮一年。于2002年8月19日因精神悲伤，突然意识丧失，晕倒在地，口唇发绀小便失禁，5min后送入我院急救中心，心电图示：尖端扭转型室速室颤，前、后反复电除颤10次，恢复窦性心律，频发房早，间歇短阵房颤，T波倒置，Q—T间期440-480ms，为防止再次室颤，于2002年9月7日安置单腔起博复律除颤器(ICD)，     

非程序性冷冻仪冻存人胚胎干细胞的方法

在人胚胎干细胞（human embryonic stem，hES）的研究中，有效的冻存方法非常重要。目前，冷冻Es细胞主要有两种方法：慢速冷冻一快速复温和超快速玻璃化法。慢冻法需要昂贵的程序性冷冻仪，而玻璃化法步骤繁琐且只能冻存小量细胞．不能满足临床应用。因此，本研究旨在寻找非程序性冷冻仪冻存大量hES细胞的方法。     

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.
