养阴清热煎剂对系统性红斑狼疮患者黏附分子表达及狼疮损伤指数的影响

目的:研究中医药对系统性红斑狼疮(SLE)的治疗作用机制及其对SLE器官损害的远期疗效.方法:1999～2003年住院及门诊的SLE患者51例,随机分为以中药养阴清热煎剂为主的中西医结合治疗组(简称治疗组)和单纯西药治疗的对照组(简称对照组),进行了治疗前后血清细胞黏附分子1(ICAM-1)、黏附分子3(ICAM-3)、P-选择素以及SLE损伤指数(SLICC/ACRDI)的研究.结果:SLE患者的ICAM-1、ICAM-3、P-选择素均较正常人明显增高;治疗组治疗后ICAM-1、P-选择素比对照组明显下降;而SLE损伤指数积分显示,治疗组比较稳定,对照组较治疗前有明显增加.结论:提示以中药养阴清热煎剂为主的治疗组对SLE患者的血清黏附分子高表达有明显的抑制作用,并对SLE的器官损害有明显的保护与修复作用.     

丹参酮ⅡA对兔髂动脉球囊损伤后胶原生成抑制的效应观察

目的:观察兔髂动脉损伤后,丹参酮ⅡA治疗组中膜平滑肌细胞(SMC)周围胶原变化的趋势.方法:取体重2.5～3kg纯种雄性新西兰大白兔30只,球囊导管扩张法制作左髂动脉内膜球囊损伤模型,术后分配到治疗组和对照组.治疗组丹参酮ⅡA稀释静脉注射,疗程6天;对照组采用等量生理盐水静脉注射.术后7天、14天和28天处死实验兔,将左侧髂动脉取出制作石蜡切片,并作胶原染色.结论:术后7天治疗组和对照组胶原纤维染色均不明显,术后14天和28天对照组SMCs周围可见胶原染色阳性,红染增多;治疗组14天SMCs周围也可见红染增多,但28天红染不明显;两组差异以术后28天明显(P=0.017);胶原染色随时间变化的趋势有统计学意义(P=0.005).结论:丹参酮ⅡA有抑制血管损伤后细胞外基质堆积的作用,从而可能有防治术后再狭窄的效应.

痰瘀同治急性脑梗死浅析

急性脑梗死现代医学又可称脑卒中，好发于中老年人，属中医中风范畴，临床表现复杂多端，大多缠绵难愈，后遗偏瘫失语等症，自古为中医内科四大疑难病证（风、痨、臌、膈）之一。我院脑病中心应用痰瘀同治法，治疗急性脑梗死，临床疗效满意，本文总结有关资料，粗略探讨如下。     

Pivotal study of iodine-131-labeled chimeric tumor necrosis treatment radioimmunotherapy in patients with advanced lung cancer.

PURPOSE: Tumor necrosis treatment (TNT) uses degenerating tumor cells and necrotic regions of tumors as targets for radioimmunotherapy. Previous studies in animal tumor models and clinical trials have demonstrated that when linked to the therapeutic radionuclide iodine-131, recombinant chimeric TNT antibody ((131)I-chTNT) can deliver therapeutic doses to tumors regardless of the location or type of malignancy. Therapeutic efficacy and toxicity of (131)I-chTNT in advanced lung cancer patients were studied in this pivotal registration trial. PATIENTS AND METHODS: Patients with advanced lung cancer were treated with systemic or intratumoral injection of (131)I-chTNT in eight oncology centers in China. The objective response rate (ORR) was assessed as the primary end point. RESULTS: All 107 patients who were entered onto the study and completed therapy had experienced treatment failure after prior radiotherapy or chemotherapy a mean of three times. The results showed an ORR of 34.6% (complete response, 3.7%; partial response, 30.8%; no change, 55.1%; and progressive disease, 10.3%) in all patients and 33% in 97 non-small-cell lung cancer patients. A biodistribution study demonstrated excellent localization of the radioactivity in tumors in both systemically and intratumorally injected patients. The most obvious adverse side effect was mild and reversible bone marrow suppression. CONCLUSION: Radioimmunotherapy with (131)I-chTNT was well tolerated and can be used systemically or locally to treat refractory tumors of the lung.     

中华眼镜蛇毒组分C与几种临床化疗药体外对人胶质瘤株作用的差异研究

背景与目的：脑胶质瘤是常见的颅内肿瘤，占脑恶性肿瘤的50％以上，化疗作为综合治疗的一项重要手段，仍存在效果不理想、易耐药等问题。本文就研究中华眼镜蛇毒组分C（Fraction C from Naja Naja Actra Venom，NNAV．FC）体外对人胶质瘤细胞株U-251的细胞毒性作用，并与几种临床脑肿瘤化疗用药进行比较，以求为脑胶质瘤的治疗提供新的化疗药物。方法：应用MTT法．观察NNAV．FC人胶质细胞瘤株U-251的细胞毒作用、量效关系等，并与依托泊苷（vp=16、鬼臼乙叉苷、Vepesid）、卫萌（替尼泊苷、鬼臼甲叉甙vm-26，Teniposide）、顺铂（Cisplatin、CDDP）、卡铂（Carboplatin）、五氟尿嘧啶（5-FU）等对上述细胞的细胞毒作用进行比较。结果：FC对人胶质瘤细胞有明显的抑制作用，其24及48h的IC50分别为5．76和7．19μg／ml，且呈良好的量效关系。结论：在本实验中，FC能有效抑制胶质瘤细胞株的生长，抑制作用与浓度呈正相关，与临床胶质瘤化疗药相比较。FC是有效地抑制胶质瘤细胞生长的药物。
