儿童脊髓内肿瘤81例

目的总结儿童脊髓内肿瘤的病理特点、临床表现和手术治疗效果,探讨其特点和规律。方法81例儿童髓内肿瘤均经显微手术切除和病理证实,进行回顾性分析。结果儿童髓内肿瘤以星形细胞瘤24例(29.6%)、室管膜瘤13例(16.0%)和表皮样囊肿11例(13.6%)为多见,其运动系统损害是儿童髓内肿瘤最常见首发症状,其次为疼痛、感觉障碍、括约肌功能障碍等。放疗用于高度恶性肿瘤。椎板成形术可以有效减少脊柱畸形发生率。结论运动系统损害是儿童髓内肿瘤最常见首发症状,感觉障碍较成人发生率低。积极手术切除能获得满意疗效。     

肾综合征出血热血清TNF-α、E-选择素、L-选择素、ICAM-1、TGF-β1的变化及其意义

目的:阐明TNF-α、可溶性E-选择素、L-选择素、ICAM-1、TGF-β1在肾综合征出血热(HFRS)发病机制中的作用。方法:34例HFRS患者(轻症组19例,重症组15例)按病期采血,分别用放射免疫法和ELISA检测TNFα、E-选择素、L-选择素、I-CAM-1和TGF-β1,并同期作肾功能和血常规检查。结果:从发热期至多尿期,血清TNF-α、E-选择素、L-选择素和ICAM-1水平均显著增高,而TGF-β1显著降低,TNF-α与BUN呈一致性变化趋势,而与血小板的变化趋势相反。结论:TNF-α、E-选择素、L-选择素、ICAM-1等细胞因子在肾综合征出血热发病机制中起重要作用,而TGF-β1水平下降可能是造成失控性全身炎症反应和多器官功能障碍综合征的重要因素之一;合理的对症治疗和适量使用免疫调节剂可望改善本病的预后。     

新生儿行为神经测定的临床观察

目的研究新生儿的神经精神行为,早期发现中枢神经系统的功能异常,以便早期干预治疗,让家长了解和关注婴儿的精神神经发育,增加保健意识。方法采用新生儿行为神经测定(NBNA)法对2000年6月-2004年10月5200例足月新生儿进行检测。结果总分>37分的为5048例,占97.07%;≤37分的为152例,占2.93%。其中缺血缺氧性脑病13例,腭裂2例,先天性听力障碍2例。结论NBNA法不仅有助于早期发现脑损伤及先天性缺陷,为及早干预治疗提供临床依据,且可增加家长对儿童保健的认识,是婴儿神经精神发育的简便实用的一种临床检测方法。     

原发性高血压血管内皮损伤与血栓前状态的研究

目的探讨内皮损伤的分子标志物与原发性高血压发生血栓性疾病的关系。方法应用酶联免疫吸附法(ELISA)分别测定98例原发性高血压患者和36例健康对照者血浆血栓调节蛋白(TM)、血管性血友病因子(VWF)、纤溶酶原激活剂抑制物-1(PAI-1)的水平变化。结果与正常对照组比较,1、2、3级高血压组VWF、PAI-1水平显著增高(P<0.05),23、级高血压组TM水平显著增高(P<0.05),与1级高血压组比较,2、3级高血压组TM、VWF、PAI-1水平显著增高(P<0.05)。结论原发性高血压病患者存在的血管内皮损伤、抗凝作用减弱、血小板粘附与聚集、纤溶活性的下降,可能是其并发心、脑血管血栓性并发症的原因之一。     

Outcomes of using Firebird rapamycin eluting stents in routine coronary intervention practice: one-year results from the pilot study of Firebird in China registry

Recent clinical trials with rapamycin-eluting stents have shown very low restenosis rates.1-4 However, the higher penetration of drug eluting stent (DES) in China is being limited by the high costs of these imported devices, especially when considering multiple stenting.     

Cardio-protective Effects of Corocalm (疏冠胶囊)on Acute Myocardial Ischemia/Reperfusion Injury in Rats

Objective: To investigate the cardio-protective effects of Corocalm (疏冠胶囊) on acute myocardial ischemia in rats, and to explore its possible therapeutic mechanisms. Methods: The acute ischemic model was prepared by ligating the left anterior descending (LAD) coronary artery in rats. The animals were divided into 6 groups, 8 in each group. The sham operated group underwent heart exposure without ligation and were treated with normal saline 3 ml/kg, while the other 5 groups, the model groups, consisted of acceptable acute ischemic model rats and were also treated with normal saline, with the Guanxin Capsule ted with 85 mg/kg and 340 mg/kg of Corocalm respectively, and the Diltiazem group, treated with Diltiazem 5 mg/kg, with all the tested drugs prepared with normal saline into equal volume ( 3 mi/kg) and administrated once via duodenum 10 min before ligation. Myocardial infarction area was determined by the quantitative histological assay with nitroblue tetrazolium (N-BT) stain. And the levels of creatine phosphokinase (CK),lactate dehydrogenase (LDH), malondialdehyde (MDA) content, and the activity of superoxide dismutase (SOD) in serum were measured by biochemical assay and spectrophotometry respectively. Besides, the blood viscosity in another 50 rats was determined, who received for 7 successive days oral administration with different concentration of Corocalm or aspirin. Results: It showed that low and high dose Corocalm could significantly reduce the infarction area, inhibit the increase of serum CK, LDH activity and MDA content, and enhance the SOD activity after ischemia/reperfusion. The whole blood viscosity at different shear rates in rats treated with high dose Corocalm was significantly lower than those treated with normal saline (P＜0.05). Conclusion: Corocalm has favourable protective effects on heart in ischemic condition, the effect of which might be through its actions in inhibiting CK and LDH activity, scavenging oxygen free radicals, and lowering blood viscosity.
