经阴道超声介入治疗多囊卵巢综合征的临床分析

目的探讨在B超引导下经阴道卵泡穿刺术(transvaginal immature follicle aspiration,TV-IMFA)治疗耐药多囊卵巢综合征(polycystic ovarian syndrom,PCOS)合并不孕患者的疗效和可行性.方法选择78例难治性PCOS患者,随机分为两组:A组(n=40)为B超引导下经阴道卵巢穿刺组(TV-IMFA),B组(n=38)为腹腔镜下卵巢打孔组(LOD),术后监测排卵,若2个月无排卵,则使用促排卵药物,同时指导性生活,并随访1a,了解妊振情况.结果 A,B两组术后内分泌激素水平都得到改善,而两组排卵率、妊振率、自然流产率差异无显著性.结论 A,B两组治疗手段不同,但具有相同的临床疗效.     

Integrated plasma cortisol concentration in children with asthma receiving long-term inhaled corticosteroids.

We assessed the effect of long-term therapy with inhaled beclomethasone dipropionate (BDP) on the pituitary-adrenal axis, by measuring the integrated concentration (IC) of plasma cortisol in eight children with asthma (age, 6-16 years) who regularly used inhaled BDP in doses ranging from 8 to 26.5 micrograms/kg (200-450 micrograms/day) for 6 months to 4 years. The control group included six children (age, 6-16 years) who had the IC of plasma cortisol measured as part of an endocrinological evaluation and were found to be healthy. Cortisol concentration was measured in blood samples collected continuously over a 24-hr period. Mean IC of plasma cortisol in the study group was significantly lower than in the healthy controls (mean +/- SD, 4.9 +/- 3.3 vs 9.1 +/- 1.9 micrograms/mL; P less than 0.02). Cortisol response to 0.25 mg ACTH (iv) was abnormal in one of the eight BDP-treated patients. No correlation was found between IC of plasma cortisol and the BDP dose, severity of asthma, height percentile, or the Tanner stage. We conclude that long-term therapy, even with relatively conventional doses of inhaled BDP may cause reduction in the normal physiological secretion of cortisol. The clinical relevance of low IC of plasma cortisol is not clear, but it may reflect partial suppression of the pituitary-adrenal axis.     

高血压病合并脑梗死的动态血压特点

目的 :观察高血压病合并脑梗死患者的动态血压特点。方法 :对 70例高血压病合并脑梗死患者和 1 0 2例单纯高血压病患者进行 2 4h动态血压监测。结果 :84 %高血压病合并脑梗死患者血压昼夜节律消失 ,而单纯高血压病患者 5 8%消失 (P <0 .0 1 ) ;高血压病合并脑梗死组 85 %出现晨峰 ,而单纯高血压病组 5 5 %出现晨峰 (P <0 .0 1 )。结论 :血压的昼夜变化和晨峰与高血压病合并脑梗死密切相关。高血压病合并脑梗死患者晨峰明显增加 ,昼夜节律消失明显     

主动免疫恢复T辅助细胞平衡治疗习惯性流产

An immediate light microscopic response of neuronal somata,dendrites and axons to contusing concussive head injury in the rat

Summary Thirty-four rats were killed by transcardial perfusion fixation 1 min after a contusing concussive head injury, and 17 rats 1 day later. From the results obtained with a new silver method demonstrating traumatically damaged neuronal somata, dendrites and axons the following conclusions were drawn: (1) outside the contused territories all features of traumatically induced neuronal argyrophilia are similar to those found in non-contusing concussive head injury, as reported in an accompanying paper; (2) within contused territories the neuronal argyrophilia is abolished by some substance released either from damaged blood vessels or from damaged parenchymal cells, while the neuronal damage otherwise underlying the induction of argyrophilia is present; (3) different phenotypes of neurons are vulnerable to different values of the parameters of the intracranial pressure wave generated by the trauma; (4) some of the neurons may recover from the traumatically induced argyrophilic damage; (5) traumatically induced inundation of neurons with extracellular tracers, as reported by other authors, and somato-dendritic argyrophilia may be different manifestations of one and the same phenomenon; and (6) diffuse primary traumatic axonal injury in human neuropathology may be closely correlated to axonal argyrophilia.
