前尿道代后尿道成形术治疗男性复杂性后尿道狭窄

目的探讨长段复杂性后尿道狭窄治疗新方法。方法采用分期前尿道代后尿道成形术治疗3例复杂性后尿道长段狭窄（6．5—10．0cm）患者。第一期行阴茎转位尿道端端吻合术，术后3—6个月行二期阴茎伸直、尿道会阴造口术，6个月后行第三期前尿道成形术（Johanson Ⅱ期尿道成形术）。结果例1术后排尿通畅，膀胱尿道造影检查示尿道通畅，双侧输尿管返流近消失，最大尿流率18．8ml／s，随访2年，最大尿流率18ml／s，无剩余尿。例2术后排尿通畅，最大尿流率19．5ml／s，无剩余尿，尿道扩张可顺利通过22F尿道探子。例3经会阴一耻骨联合径路行第一期阴茎转位尿道端端吻合术、尿道直肠瘘、尿道会阴瘘切除、修补术，术后尿道直肠瘘及尿道会阴瘘治愈，但因耻骨联合切口感染致吻合口狭窄，有待进一步治疗。结论分期前尿道代后尿道加前尿道重建方法是治疗男性长段复杂性尿道狭窄的有效方法。     

骨调素和单核细胞趋化蛋白在大鼠梗阻性肾病中的表达及可能作用

目的:探讨骨调素(OPN)和单核细胞趋化蛋白(MCP-1)在大鼠梗阻性模型中的表达及其在肾脏纤维化发病机制中的作用.方法:采用-单侧输尿管结扎制造梗阻性肾病模型,分别于造模后7 d、14 d取肾组织,应用HE染色观察肾脏病理改变,免疫组化方法检测肾组织畔OPN和MCP-1蛋白的表达,应用逆转录-聚合酶链式反应(RT-PCR)法观察肾组织中OPN mRNA和MCP-1 mRNA的变化.结果:OPN、MCP-1表达主要位于肾小管上皮细胞,随着梗阻时间的延长,肾组织中OPN、MCP-1蛋白和mRNA表达明显增加.结论:OPN、MCP-1蛋白和mRNA在梗阻性肾病大鼠肾组织表达明显增加介导炎症过程,参与肾间质纤维化.     

妇产科手术后粘连性肠梗阻的治疗

目的:探讨妇产科手术后粘连性肠梗阻的治疗 .方法:分析30例妇产科手术后粘连性肠梗阻的临床特点和治疗.结果:保守治疗成功16例(53.3%),保守无效而中转手术14例(46.7%),9例行肠切除术.结论:妇产科手术后粘连性肠梗阻易发生肠绞窄,临床表现不典型,应采取积极的手术疗法.     

CT对肝外胆管梗阻性质的鉴别诊断

目的：探讨良恶性肝外胆管梗阻病变的CT表现及其诊断意义。方法：回顾经手术病理证实的肝外胆管梗阻病变76例(良性34例，恶性42例)。结果：肝内胆管呈枯枝状轻中度扩张，肝内外胆管不一致扩张(内轻外重)，肝外胆管远段梗阻，梗阻部胆管呈削尖状狭窄，肝外胆管壁呈弥漫环形增厚，对良性梗阻的诊断有重要意义。肝内胆管呈软藤状重度扩张，肝外胆管中段梗阻，梗阻部胆管呈伴或不伴肿块的截断型或突然狭窄型，肝外胆管壁局限不规则增厚，高度揭示恶性梗阻。结论：良恶性肝外胆管梗阻病变均有特征性CT表现，通过分析胆管形态和临床资料基本能判断梗阻的性质。     

Ultrasound evaluation of female urinary incontinence

Thirty women, 25 with incontinence and five asymptomatic volunteer control subjects, were evaluated urodynamically by a variety of techniques, including ultrasound cystourethrography. The ultrasound evaluation was found to be a helpful adjunct in diagnosis. In comparison with radiologic techniques it offers more safety, more comfort, more privacy, more viewing time, and less cost. Bladder and urethral morphology during voiding activity and the amount and direction of urethrovesical mobility are easily determined by utilizing ultrasound techniques.     

The value of the acoustic analysis of pathological infant cry and breathing noise in everyday practice

During a period of twenty years [1969-1988] the author has observed 614 cases of congenital malformations and noninflammatory diseases of the larynx in infants and young children, Budapest. He summarizes the most characteristic symptoms of laryngeal pathology in infants, and discusses the diagnostic possibilities. Among the latter, spectrographic analyses complemented by auditory evaluation of pathological cry and different breathing noises play an important role. Based on his investigation author differentiates 20 kinds of pathological crying sounds and 4 basic forms of stridor. He describes the acoustic attributes of different pathological sound phenomena and summarizes characteristic voice changes.     

上腔静脉梗阻外科治疗(附5例报告)

本文通过应用大隐静脉、人造血管与经戊二醛处理后的新生儿脐带静脉,分别为5例上腔静脉梗阻进行6例次转流术或上腔静脉重建术,认为脐带静脉具有取材容易,处理简单,血管口径一致,无静脉瓣,缝合较易等优点;大隐静脉适用于不开胸者,为减轻症状治疗首选材料;人造血管不宜代上腔静脉。上腔静脉梗阻手术治疗指征是,当梗阻发生在奇静脉或其以上,侧枝循环少,左右无名静脉通畅,病人有不能耐受的脑部和呼吸道症状,估计能够耐受开胸手术。     

Specific sensitization to common allergens and pulmonary function in the European Community Respiratory Health Survey

BACKGROUND: The role of atopy in the evolution to chronic obstructive disease remains controversial. AIM: We aimed to assess the association between individual sensitization to common allergens and lung function. METHOD: We analysed data from 12,687 subjects aged 20 to 44 years, from 34 centres in 15 countries participating in the European Community Respiratory Health Survey (ECRHS). Participants performed a blood test, lung function test, methacholine challenge, and answered an administered questionnaire. The relationships between specific IgE, FEV1 and FEV1/FVC ratio were assessed for each study centre stratified by sex, followed by random effects meta-analysis. RESULTS: Asthmatics sensitized to house dust mite had a lower FEV1 (-119 mL in women and -112 mL in men) and FEV1/FVC ratio (-1.95%, and -2.48%) than asthmatics without sensitization. Asthmatics sensitized to cat had a lower FEV1 (statistically significant for women only) and a lower FEV1/FVC ratio. Asthmatic women sensitized to grass had a lower FEV1 and a lower ratio, and those sensitized to Cladosporium had a lower FEV1. A weak association was found with sensitization to cat and to Cladosporium among non-asthmatic women, which disappeared after adjusting for BHR. CONCLUSION: We conclude that atopy was related to a lower lung function, which was only apparent among asthmatics. This relationship was explained by specific sensitization to cat and to house dust mite, the latter being homogeneous across areas.     

SURGERY OF PERIURETERIC OBSTRUCTION IN 101 CHILDREN OVER ONE YEAR OF AGE

One hundred and one children over 1 year of age have had surgery for pelviureteric obstruction over an 11 year period. The common clinical features were abdominal pain, urinary infection or haematuria, but number presented as an incidental finding. Less commonly, the patients presented with an abdominal mass or with hypertension. The diagnosis was usually made on intravenous pyelography (IVP) but in the latter part of the series, renal nuclide scan (RNS) and ultrasonography (US) were preferred. Ninety–three patients had unilateral pyeloplasty, three had bilateral pyeloplasty and five had nephrectomy or heminephrectomy. Whereas initially nephrostomy drainage was used in the majority of patients after pyeloplasty, trend away from nephrostomy evolved in the latter part of the series. With experience, the incidence of postoperative complications was also reduced and there was reduction in the period of hospitalization. Clinical results were consistently satisfactory. Postoperative assessment after pyeloplasty was made by IVP and/or RNS and also US. A review of these investigations showed that RNS provided more factual information of the result when compared with the IVP.
