改良的HAMPT方案治疗难治性急性淋巴细胞性白血病

我们将常规的ＨＡＭＰＴ方案中的氨甲喋呤（ＭＴＸ）剂量改为大剂量组成良的ＨＡＭＰＴ方案治疗难治性急性淋巴细胞白血病（ＡＬＬ）２０例，１７例完全缓解，３例部分缓解。其中１６／１７例一疗程则获完全缓解（ＣＲ），ＣＲ率８５％，诱导缓解时间平均１７天。本方案疗效较满意，副作小用，可作为难治作ＡＬＬ治疗的较好方法。     

甲氰咪胍致昏迷1例

甲氰咪胍现临床广泛应用于治疗消化性溃疡，对胃酸分泌、组织胺、促胃液素等的分泌均有强大的抑制作用，对急性胃出血也有较好的止血作用。但有关副作用的报道也逐年增多。现将甲氰咪胍致昏迷1例报告如下。     

石杉碱甲和乙促进小鼠的空间辨别学习和记忆

石杉碱甲和乙是从石杉科石杉属植物蛇足石杉[Huperzia scrrata(Thunb.)Trev.]中分得的二个新生物碱。“Y”迷宫实验表明,ip Hup-A 0.075～0.125 mg/kg或Hup-B 0.4～0.8mg/kg,均能明显促进小鼠的空间辨别学习,并能显著预防CO₂产生的短时识别障碍,促进记忆保持和记忆再现。ig Hup-A 0.1～0.3 mg/kg或Hup-B 0.8 mg/kg也有促进学习的作用。促进作用Hup-A>Phys>Hup-B。剂量与效应曲线呈倒U型。     

异丙酚静脉全麻复合硬膜外腔阻滞麻醉期间CO2气腹对血流动力学和氧耗的影响

OBJECTIVE: To investigate the effects of intraperitoneal CO2 insufflation on the hemodynamics, oxygen consumption (VO2) and carbon dioxide production (VCO2) during intravenous anesthesia with propofol in combination with epidural block. METHODS: Intratracheal intubation was performed after rapid induction of anesthesia and mechanical ventilation was given. Maintenance of anesthesia was achieved using continuous intravenous propofol infusion (2 mg/kg/h) ?N2O inhalation and intermittent epidural administration. Indices of hemodynamics and respiratory function were collected 5 min before induction, 1 min before CO2 insufflation, and 5, 10, 20, 30, 40, 50, 60 min after the start of insufflation and 5 min after the termination of insufflation. RESULTS: The mean arterial pressure (MAP), heart rate (HR), end-tidal PCO2 (P(ET)CO2), VO2 and VCO2 1 min before insufflation were markedly reduced(P<0.01), compared with those recorded before induction. MAP and HR did not undergo any conspicuous changes during CO2 insufflation and 5 min after insufflation termination. Compared with that 1 min before insufflation, PETCO2 was significantly increased 20 min after the start of insufflation (P<0.01), and subsequently carried on the increase though of a lesser scale. VO2 and VCO2 gradually rose after the start of insufflation, and VO2 presented a significantly elevation (P<0.01) 10 min after the insufflation while VCO2 did not show this marked increase(P<0.05) till 20 min after the insufflation in comparison with the levels before insufflation. Subsequently, VO2 continued to rise and VCO2 also retained the increase but of smaller magnitude. CONCLUSION: Intravenous propofol anesthesia combined with epidural block assisted by well-managed excessive ventilation before insufflation can alleviate the adverse effects of CO2 insufflation on respiratory and circulatory systems.     

复方丹参注射液与甲钴胺联用治疗糖尿病周围神经病变

糖尿病周围神经病变是糖尿病十分常见的并发症,也是糖尿病致残的常见原因之一,由于其原因不甚明了,目前的治疗手段也有限。近年来,国内多采用甲钴胺(商品名:弥可保)改善糖尿病周围神经病变的症状,但其疗效也未令人满意。为此,我们采用复方丹参与甲钴胺联合治疗糖尿病周围神经病变三个月,与单用甲钴胺对比,疗效满意。现报告如下。     

肿瘤乏氧组织显像剂的研究进展

乏氧组织显像剂能选择性地滞留在乏氧组织或细胞中,通过无创性的核医学正电子发射体层摄影术/单光子发射计算机体层摄影术可评价实体肿瘤缺氧状态.一些显像剂适宜进行乏氧显像并能很好地反映肿瘤乏氧及其程度等情况,这些信息在肿瘤的临床诊断决策中起到重要作用.     

多种药物与腹腔镜协同治疗PCOS疗效分析

资料与方法对象:随机选择2003年2月~2006年5月在我院妇科内分泌门诊就诊且确诊为PCOS患者90例,年龄在18~34岁之间,平均29.56±3.2岁。均存在不同程度的闭经、月经稀少、肥胖、多毛、不孕、痤疮等症状。经超声检查双侧卵巢均匀性增大,呈多囊样改变,激素测定中性激素、体重指数、胰岛素均有不同程度的异常。所有患者经妇科检查、输卵管碘油造影示盆腔正常,肝肾及其他功能正常,无其他内分泌疾病。近6个月无激素治疗史。方法:将90例患者随机分成A、B两组,A组单纯腹腔镜卵巢打孔;B组服用达因-35和二甲双胍3个月后行腹腔镜卵巢打孔。方案A组:…
