多发性硬化干扰素治疗的概况及进展

多发性硬化 (ＭＳ)是临床常见的中枢神经系统 (ＣＮＳ)脱髓鞘性自身免疫性疾病。作为一种难治性疾病 ,人们对其发病机制及治疗进行了不断的深入研究。干扰素(ＩＦＮ)疗法成为近 2 0年研究的热点之一 ,Ⅰ型ＩＦＮ作为目前唯一一种有望改变ＭＳ病程的药物 ,被誉为开创了ＭＳ治疗的新纪元[1] 。本文就ＭＳ干扰素治疗的发展概况及进展作一综述。1　ＭＳ的发病机制与ＩＮＦ的治疗机制　　尽管经过了 1 0 0多年的研究 ,ＭＳ的确切病因及发病机制仍然未被完全阐明。与ＭＳ相类似的实验动物模型即实验性变应性脑脊髓炎 (ＥＡＥ)提示自身免疫反应在Ｍ…     

大剂量干扰素可为丙肝患者带来长期益处

感染慢性丙肝病毒(HCV)的患者经大剂量α-干扰素(α-IFN)治疗6个月后,其肝纤维化的进展可得以抑制,该作用效果可持续达5年以上。     

人α1,2岩藻糖苷转移酶基因在猪动脉内皮细胞的表达

目的通过基因工程技术使人α1,2岩藻糖苷转移酶(HT)基因在猪动脉内皮细胞(PAEC)表达,削减异种抗原αGal的表达。方法构建pcDNA3HTcDNA重组质粒,体外培养PAEC,脂质体转染法将pcDNA3HTcDNA转染PAEC,新霉素(G418)筛选具有抗性的细胞克隆,对其用PCR检测重组质粒的整合,流式细胞术(FCM)检测转染细胞H抗原和异种抗原αGal的表达。分别以未转染的PAEC和人脐静脉内皮细胞(HUVEC)作为对照。结果重组质粒转染PAEC经筛选得到抗性细胞克隆,PCR扩增出人HT基因片段,FCM检测转染细胞H抗原表达升高,αGal表达明显降低。结论成功构建了pcD NA3HTcDNA重组质粒,并使人HT基因在PAEC表达,抑制了αGal的合成。     

慢性乙型肝炎干扰素a-2b治疗后复发的治疗效果对比

目的 :观察干扰素a - 2b远期疗效。方法 :将在我科住院的曾用干扰素a - 2b抗病毒治疗和未抗病毒治疗的复发慢性乙肝患者 ,在相同治疗条件下 ,观察其血清总胆红素 (SB)、谷丙转氨酶 (ALT)、血清白蛋白(ALB)的变化情况及相应的住院时间和住院费用。结果 :与未抗病毒治疗的复发慢性乙肝患者相比 ,干扰素a- 2b治疗后的慢性乙肝患者再次出现肝功能损害时 ,其治疗有效率明显提高 (P <0 .0 5 ) ,血清总胆红素 (SB)下降速率明显增快 (P <0 .0 5 ) ,平均住院时间及治疗费用明显减少 (P <0 .0 5 )。结论 :干扰素a - 2b可能改善慢性乙肝的预后。     

~3H-α-第二丁基对羟基苄醇在家兔体内的药物动力学研究

本文报道给家兔注入不同剂量的~3H-α-第二丁基对羟基苄醇,观察该药在其体内的药物动力学。结果表明,血中分布相快,消除相慢,消除半衰期T_1/1β为12h。经F值检验和理论计算值与实测值的契合程度比较,表明该药在兔体内的运转符合二室开放模型的动力学方程。     

补肾解毒汤联合干扰素治疗慢性乙型肝炎25例分析

干扰素是目前公认有效的治疗乙型肝炎药物，但是荟萃分析表明，经干扰素治疗慢性乙型肝炎4～6个月后，HBVD-NA（杂交法）及HBeAg的转阴率分别为37％及33％^[1]，其疗效仍不尽如人意。因此如何寻找一种方法提高疗效值得进一步探讨。笔者于2004年1月-2006年12月自拟中药补肾解毒汤联合干扰素治疗慢性乙型肝炎取得较好的疗效，现报道如下。[第一段]     

The correlation between TNF-α, IL-6 in cervical mucous during follicular development and ovulation stimulation in different protocols

Objective To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods 36 infertile women were set up as experimental groups,divided into CC, HMG, IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase, luteal phase and ovulation phase were collected.TNF-α, IL-6 levels in cervical mucous were measured by radioimmunology assay (RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results (1) TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase, reached to peak during ovulation phase, and decreased during luteal phase (P＜0.05).IL-6 levels had no obvious periodical changes.(2) Compared with CC and control group, levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher (P＜0.05).(3) Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter (r=0.261, r=0.192 respectively,P＜0.05).(4) TNF-α and IL-6 showed positive correlation in the reproductive cycle (r=0.782,P＜0.05).Conclusions (1) TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2) TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4) TNF-α and IL-6 may have coordination properties and participate in the same biological effects.     

卡介菌多糖核酸联合微波治疗尖锐湿疣临床观察

目的观察卡介菌多糖核酸对尖锐湿疣治愈时间内微波治疗次数的影响。方法两组均用微波清除疣体,每周1次,直至疣体不再出现;治疗组同时肌注卡介菌多糖核酸,对照组肌注干扰素α-2b,均每周3次。两组均在疣体不再出现后巩固用药2个月,随访3个月。结果两组均治愈,治疗组平均应用微波治疗4.17次(1~18次),对照组平均应用微波治疗4.24次(1~20次),两组比较差异无显著性(P>0.05)。结论卡介菌多糖核酸与干扰素的疗效相当,但前者价格低、副作用小,值得临床应用。
