Value of serum progesterone for ectopic pregnancy in therapeutic effect monitoring]

OBJECTIVE: To study the value of serum progesterone in selecting the candidate patients with ectopic pregnancy (EP) for methotrexate (MTX) treatment and in monitoring the effect of the treatment. METHODS: Thirty-seven EP patients who were given single-dose intramuscular injection with 50 mg/m2 MTX were divided into success and failure groups according to the effect of the treatment. The serum progesterone concentrations in these patients were measured and compared between the 2 groups, and the receiver-operator curves (ROC) were used to determine the critical serum progesterone levels for assessing the effect of MTX treatment. The time consumed respectively by serum progesterone and beta-human chorionic gonadotrophin (beta-hCG) decreasing to below normal level was also compared. RESULTS: The serum progesterone concentrations of the success group (7.93+/-2.02 ng/ml) were significantly lower than those of the failure group (14.53+/-1.72 ng/ml, P<0.05). The recommended critical level for assessing the effect of MTX treatment for EP patients was 11 ng/ml according to the ROC, and the time for serum progesterone decreasing to below normal level was significantly less than that for beta-hCG. CONCLUSION: Serum progesterone can be used as an index for selecting candidate EP patients for MTX treatment, and also as a good indicator for assessing the therapeutic effect after treatment.

经尿道电切与气化切割和激光治疗前列腺增生症的疗效比较

目的 :比较经尿道电切前列腺术 (TURP) ,经尿道前列腺气化切除术 (TUVP)及经尿道接触式激光前列腺切除术 (TULP)的治疗效果。方法 :在 30 0 0例前列腺增生症患者中 ,按三种术式各随机抽取 2 0例术前条件具有可比性的患者 ,进行疗效比较。结果 :3种术式患者手术前后前列腺症状评分 (IPSS)、生活质量评分(QOL)、最大尿流率 (MFR)、剩余尿 (PVR)比较均得到显著改善 (P <0 .0 1) ,3组之间相比差异无显著性意义(P >0 .0 5 )。手术时间 :TUVP及TURP组明显短于TULP组 (P <0 .0 1) ,术中失血量及术后置管时间 :TUVP及TULP组明显少于TURP组 (P <0 .0 1)。TURP组术后继发感染、出血、暂时性尿失禁发生率少于TUVP及TULP组。结论 :3种术式治疗效果相同 ;TUVP操作简单、安全 ,对初学者来说尤其适宜 ;TURP仍为治疗BPH的金标准术式     

动态脑电图与视频脑电图对癫癎诊断的对照研究

目的:观察24小时动态脑电图与视频脑电图对癫发作类型鉴别的价值。方法:242例患者进行24小时视频脑电监测,陪同家属做记录。结果由两名医师判定,一人关闭视频进行分析作为动态脑电组。一人打开视频分析作为视频脑电组。结果:242例患者中63例临床发作伴癫样放电,视频脑电监测后符合例数53例(84%),动态脑电监测后符合例数39例(61·9%),有显著性差异。结论:视频脑电监测与动态脑电图对癫发作类型的鉴别有显著的差异,视频脑电图更准确。
