Intravenous cidofovir treatment for recalcitrant warts in the setting of a patient with myelodysplastic syndrome

Cidofovir is an acyclic nucleoside phosphonate with broad-spectrum activity against DNA viruses, including human papilloma virus (HPV). However, data on the efficacy of cidofovir in an immunosuppressive setting remain contradictory. We report for the first time on the promotion of the healing of recalcitrant warts in a patient with myelodysplastic syndrome with intravenous cidofovir treatment.     

二甲双胍对多囊卵巢综合征患者胰岛素样生长因子-1的影响

目的探讨二甲双胍对多囊卵巢综合征（PCOS）患者血清胰岛素样生长因子-1（IGF-1）及胰岛素样生长因子结合蛋白-1（IGFBP-1）水平的影响及其作用机制，明确二甲双胍治疗的临床效果。方法2002年1—11月对山西医科大学第二医院24例PCOS患者给予二甲双胍500mg，一日3次，8～24周治疗，比较治疗前后血清IGF-1、IGFBP-1、空腹胰岛素及睾酮水平，并对月经恢复、排卵、妊娠情况进行分析。结果二甲双胍可降低血清空腹胰岛素及睾酮水平，能显著升高IGFBP-1水平，治疗前后血清IGF—1水平差异无显著性。单纯二甲双胍治疗后月经恢复率为41．67％（10／24）；自然排卵率为25．00％（6／24），自然妊娠率为12．50％（3／24）。二甲双胍加促排卵治疗共18个周期，排卵周期率66．67％（12／18），妊娠周期率为11．11％（2／18）。结论二甲双胍可以降低血清空腹胰岛素及睾酮水平，增高IGFBP-1水平，可以改善卵泡微环境，有助于月经恢复，提高促排卵和妊娠率．是治疗PCOS的重要手段。     

2 121例老年急性冠脉综合征患者血清脂类浓度的分析

目的分析60岁以上老年人血清脂类水平的参考值,并探讨急性冠脉综合征与血脂指标的相关性.方法将3 766例健康成人分为≤60岁和＞60岁的两个年龄段,采用生物化学的方法测量他们的血脂水平,找出60岁以上老年人的脂类参考值.同时分析2 121例老年急性冠脉综合征病人的脂类指标.结果 60岁以上老年人血脂参考值为:TC 4.65±1.96×1.05mmol/L;TG 1.02±1.96×0.45mmol/L;HDL-C 1.47±1.96×0.40mmol/L;LDL-C 2.98±1.96×0.56mmol/L;ApoA1 1.32±1.96×0.25g/L;ApoB 0.99±1.96×0.35g/L,并且急性心肌梗死和不稳定性心绞痛病人血清脂类各项指标之间没有显著性差异.结论血清LDL-C/HDL-C＞5和TG ≥1.9mmol/L这两项联合指标比其他单独指标与老年人急性冠脉综合征关系更密切.     

肾综合征出血热患者T细胞亚群数量与白细胞介素2,4水平变化的关系

采用ABC免疫组化染色法及单克隆抗体夹心法ELISA，同步检测了34例肾综合征出血热（HFRS）患者外周血T细胞亚群数量和血清白细胞介素2和4（IL－2、IL－4）水平。发现HFRS病程中各T细胞亚群数量均有不同程度的升高，其中CDS阳性T细胞在各病期均有升高。IL－4水平升高仅见于发热期．而IL－2的升高主要在低血压期和少尿期。病程中有CD4／CD8比值的下降甚至倒置。这种比值的变化与IL－2和IL－4的动态变化有一定的相关性。结果揭示，在HFRS发病机理中存在Thl型和Th2型免疫反应等多种免疫病理机制。     

Precise and limited decompression for lumbar spinal stenosis

Summary Fifty-eight consecutive patients with lumbosacral nerve root entrapment due to spinal stenosis were treated with modified microsurgical decompression. Only the clinically relevant sides and levels were decompressed while the spinous processes, the interspinous ligaments, the medial portion of ligamentum flavum and the functionally important parts of the facet joints were preserved. The reviewers rated recovery as good or excellent in 71% of patients while patient self-assessment indicated 76% good or excellent outcome. These data suggest that microsurgical decompression of spondyloarthritic changes can effectively relieve the signs and symptoms of nerve root compression and that with careful evaluation of all available data the number of nerve roots requiring decomperession is often fewer than what is suggested by diagnositic images alone.     

艾滋病142例临床表现分析

目的艾滋病(AIDS),是严重危害人类健康的疾病,临床上症状多变,应提高对AIDS的认识。现将作者在西非工作期间收治的142例AIDS病例的临床表现作一介绍。方法病例均为当地黑人居民,男性89例,女性53例,年龄14～45岁,平均年龄27.65岁。用酶联免疫吸附法和快速法检测患者血清中HIV—1和 HIV—2抗体。结果 HIV—1型25例(35.00％);HIV-2型74例(52.11％);混合型32例(22.53％)。临床表现为脑膜脑炎或脑炎7例(4.93％);肺型27例(19.01％);胃肠道感染84例(59.15％):包括急性48例(33.80％),慢性24例(16.90％),急腹症12例(8.45％);皮肤粘膜损害18例(12.68％):卡波齐肉瘤6例(4.23％),带状疱疹2例(1.41％),皮炎10例(7.04％),病死率19.72％(28/142)。其传播途径以性传播为主,高达78.87％(112/142),其次是密切生活接触,未发现吸毒或输血者。结论艾滋病病死率高,病情复杂,且目前尚无特效药物,必须引起医护人员高度重视。     

Acute Leukemia in an Infant with Marfan's Syndrome: A Case Report

We describe a familial case of Marfan's syndrome with associated intrathoracic stomach detected during the neonatal period. The patient developed a primitive leukemia at 3 months of age. Acute leukemia in a patient with Marfan's syndrome has not previously been reported.     

Large granular lymphocyte expansions in patients with Felty's syndrome: analysis using anti-T cell receptor V beta-specific monoclonal antibodies.

Felty's syndrome (FS), the association of rheumatoid arthritis (RA) and idiopathic neutropenia, remains an unexplained phenomenon. HLA-DR4 is found in over 90% of cases. Patients with FS may have a T cell lymphocytosis of CD3+CD8+CD57+ large granular lymphocytes (LGL syndrome). In this study of 47 patients with FS, 19% had clear evidence for LGL expansions, while in total 42% had variable evidence for the LGL syndrome using currently available techniques. Of these T cell expansions, 76% were clonal, as demonstrated by Southern blotting and analysis with T cell receptor (TCR) beta chain constant region probes. This technique may fail to detect clonal populations in some patients. Cytofluorographic analysis using antibodies specific for TCR V beta chains identified patients with clonal LGL expansions with results comparable to those obtained with Southern blotting. No evidence for shared V beta usage among expansions from different patients was seen. The role of LGL in RA and FS is currently unclear, but this technique offers a practical and accessible means of identifying patients with LGL expansions, as a starting point for further investigation.
