Remission following an elemental diet or prednisolone in Crohn's disease

The short- and long-term effects of an elemental diet in children with acute Crohn's disease were compared with those of prednisolone in historical controls. Clinical remission was induced in 25 of 30 and in 18 of 28 episodes treated for six weeks with an elemental diet and prednisolone. Patients with proximal disease had longer remission after treatment with an elemental diet (p < 0.05) than did patients with colonic disease after treatment with prednisolone (p < 0.01). Disease activity index score improved in both groups compared with the pretreatment scores (p < 0.05). However, the improvement in the elemental diet group was significantly better than in the prednisolone group (p < 0.001). Changes in linear growth were better after treatment with an elemental diet compared with steroids (p < 0.001). Serum albumin and haematocrit concentrations all improved significantly in the children treated with an elemental diet (p < 0.001) but not in those treated with steroids. Thus an elemental diet was better than prednisolone in proximal disease and confirmed improved growth and nutritional status.     

不同内耳畸形人工耳蜗植入效果分析

目的 就不同内耳畸形人工耳蜗植入特点及效果进行分析,积累经验。方法 1996年1月～2004年5月北京同仁医院共开展多道人工耳蜗植入术410例(410耳),对其中双侧内耳畸形患者82例(82耳)进行回顾性分析,就不同原因内耳畸形的人工耳蜗植入手术特点及术后开机调试特点与耳蜗形态正常的人工耳蜗植入者进行了比较。结果 ①所有内耳畸形患者人工耳蜗植入术后都有听觉;②内耳畸形人工耳蜗术中容易出现井喷;③82例中除2例患者各遗留2对蜗外电极外,其余电极均完全植入蜗内;④术后无面瘫、脑脊液漏等并发症;⑤术后开机调试数值与结构正常植入者接近,无统计学差异(P>0.05);⑥术后经过语训,1年后听力及言语能力均有不同程度的提高。结论 伴有内耳发育畸形的深度感音性聋患者可以行人工耳蜗植入手术,植入效果与耳蜗发育正常患者的人工耳蜗植入效果基本一致,人工耳蜗植入术可以作为伴有内耳畸形的深度感音性聋患者的治疗和康复手段。     

Le syndrome de Smith-Magenis

Smith-Magenis syndrome is caused by a 17p11.2 deletion. It associates mental retardation, facial dysmorphism and brachydactyly; aberrant behavior and major sleep problems are present in 70% of the cases. It is probably under-diagnosed because the facial abnormalities are mild and the behavioral problems with hyperactivity and self-injuries are dominant, leading to the diagnosis of psychiatric pathology. However these behavioral problems are sufficiently characterized to allow the diagnosis of the syndrome and look for a 17p11.2 microdeletion. Otorhinolaryngologic, ophtalmologic, cardiac and renal abnormalities can be associated and their evaluation is necessary. Smith-Magenis syndrome is considered as a contiguous gene syndrome. Genes have been mapped and isolated to the critical region, but their participation in the pathogenesis of the syndrome remains unclear.     

22例胸廓、脊柱畸形青年肺通气功能、右心改变相关性分析

目的 对胸廓畸形程度与肺通气功能、右心改变作相关性分析。方法 对22例18－22岁胸廓、脊柱畸形青年,以笔者拟定的“身高形变指数”、“胸廓形变指数”及按文献方法测定的脊柱畸变成角度数,综合判断残疾程度,同时检测其血氧饱和度、肺通气功能、心电图及超声心动图,综合评价其肺呼吸功能和右心改变,作相关分析。结果 初步显示本文所拟残疾指标的适用性以及与通气功能的相关性,而与右心改变尚未显示明显的相关性;部分指标提示脊柱中段变形可导致右心改变。结论 进一步证明胸廓、脊柱残疾导致慢性肺源性心脏病在发病机制上与COPD类疾病的差异。

Hyperbilirubinemia, hypocarbia and periventricular leukomalacia in preterm infants: relationship to cerebral palsy

This study comprised 103 preterm infants with a gestational age less than 33 weeks who were born in Tampere University Hospital and who were followed up to two years of age. Sixty-four perinatal variables were compared to ultrasound findings in the neonatal period and neurologic handicap at the age of two years. Duration of hypocarbia (PCO2 < or = 30 mmHg) during the first 72 h and hyperbilirubinemia (the mean level of serum total bilirubin) at three days of age were independently and significantly related to periventricular leukomalacia, but not directly to cerebral palsy. The only perinatal variables related independently and significantly to cerebral palsy at two years of age were periventricular leukomalacia and ventriculomegaly. According to these results, periventricular leukomalacia was the main predictor of cerebral palsy in preterm infants. In addition to hypocarbia, hyperbilirubinemia may also be involved in the pathogenesis of extensive (severe cystic) periventricular leukomalacia.

胃癌组织中Survivin外显子1甲基化状态的分析

目的：研究胃癌组织Survivin外显子1去甲基化与Survivin mRNA表达以及临床病理参数之间的关系。方法：25例胃癌及与其配对的正常胃组织DNA经甲基化敏感性限制性内切酶HpaⅡ和MspⅠ处理后用SYBR Green Ⅰ实时荧光PCR对Survivin外显子1进行检测，Survivin mRNA的表达水平采用实时荧光定量PCR的方法进行检测。结果：Survivin外显子1去甲基化率在胃癌组织和癌旁组织分别为96．0％（24／25）和20．0％（5／25），χ^2=29.639，P〈0．001。在25例胃癌组织中有22例（88．0％）发生Survivin mRNA过表达，并且表达与去甲基化呈正相关，rs=0．5528，P=0．00416。没有发现去甲基化与年龄、性别、肿瘤大小、病理分级、临床分期和转移与否等病理参数之间存在统计学上的相关性，P〉0．05。结论：Survivin外显子1去甲基化增强Survivin mRNA的表达，可能是胃癌发生和发展过程中的早期事件。
