立止血灌肠治疗急性下消化道出血的护理体会

下消化道出血以息肉、肿瘤、急性肠病及血管畸形多见,而急性出血往往是血管破裂所致。我院于2001年至2002年收住急性下消化道出血患者32例,经输液输血一般对症处理的基础上,加用立止血灌肠,经过精心护理治疗,效果较好,现     

急性心肌梗塞病人Q-T离散度变化及临床价值

急性心肌梗塞病人Ｑ┐Ｔ离散度变化及临床价值许美华１逢世敏１徐进亮２Ｑ－Ｔ离散度（Ｑ－Ｔｄ）指心电图各导联面Ｑ－Ｔ间期存在的差异，与心肌复极的不同步有关。Ｄａｙ等〔１〕研究表明，校正的Ｑ－Ｔ间期（Ｑ－Ｔｃ）及离散度（Ｑ－Ｔｃｄ）更能准确反映心肌离散程度...     

人类白细胞抗原-G蛋白在星形细胞肿瘤组织的表达

胶质瘤存在免疫耐受。而人类白细胞抗原-G(HLA-G)是一种非经典人类白细胞抗原,有研究表明HLA-G作为免疫耐受分子,在肿瘤免疫逃逸中可能具有重要作用。我们采用免疫组织化学、蛋白印迹实验观察HLA-G蛋白在星形细胞性肿瘤表达情况。     

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.     

两种单静脉法与传统Amplatzer法治疗动脉导管未闭

目的探讨两种单静脉入路法和动静脉双入路法治疗PDA各自的优缺点及最佳适应症,为PDA患者选择合理介入治疗方法提供依据。方法103例PDA患者经三种不同介入方法治疗,其中单静脉入路超声法37例,单静脉入路造影法14例,动静脉双入路法52例。PDA的位置、形态、大小经不同方法观察,单静脉超声法经超声观察,单静脉造影法在PDA内或降主动脉近PDA口外造影观察,动静脉双入路在主动脉弓降部侧位造影观察。选择合适型号的Amplatzer伞经股静脉建立的轨道进行封堵。术后15 min经胸超声及心脏听诊判断有无分流。术前、术后均行血流动力学测定,术后3 d、1个月复查超声心动图,观察大动脉水平有无分流及动脉导管未闭再通。结果103例患者全部一次封堵成功,技术成功率100%。术中操作平均透视时间(10.45±4.35)min,心导管检查测肺动脉收缩压由术前轻度增高[(33.2±3.11)mmHg]降为正常[(22.03±5.3)mmHg]。术后即刻所有患者心前区双期连续性杂音消失,术后无残余分流,无任何并发症发生,随访1个月未发生动脉水平分流及动脉导管再通。结论单静脉入路Amplatzer封堵器治疗动脉导管未闭简化了手术程序,不用或减少造影剂用量,缩短了操作透视时间,手术成功率高,疗效可靠,值得推广应用。
