西罗莫司与未成熟树突状细胞延长小鼠皮肤移植存活时间的协同作用

目的 研究西罗莫司（SRL）对小鼠骨髓源树突状细胞（DC）分化及成熟的影响，观察西罗莫司与未成熟树突状细胞在延长小鼠皮肤移植存活时间中的协同作用。方法 （1）在诱导C57BL／6小鼠骨髓细胞定向分化为DC时加入SRL，通过流式细胞仪检测CD11c、CD86及MHCⅡ类分子表达情况，经脂多糖（LPS）刺激后，再检测各分子表达的变化。（2）通过单向混合淋巴细胞反应（MLR）观察经SRL处理的DC刺激同种异基因小鼠T细胞增殖情况。（3）以C57BL／6小鼠为供者，BALB／c小鼠为受者建立皮肤移植模型。观察皮肤移植前7d经尾静脉注射供者未成熟DC及经胃管连续灌注SRL7d的受者移植皮片存活情况及组织学变化。结果 （1）经SRL处理的DC表面CD11c表达仅有轻度降低，但CD86和MHCⅡ类分子表达明显减少。（2）MLR显示经SRL处理的DC刺激同种异基因小鼠T细胞增殖的能力降低。（3）受者皮肤移植术前联合应用供者未成熟DC和SRL，可减轻移植皮片炎症反应并延长其存活时间。结论 SRL对DC分化的影响不明显，但可抑制DC发育成熟。受者术前应用SRL和未成熟DC可延长皮肤移植的存活时间。

目的 探析Waveone Gold、Protaper、MTwo及Reciproc 4种不同镍钛器械在磨牙弯曲根管中的应用效果。方法 收集100颗弯曲离体磨牙,采用随机数字表法分为五组,分别使用Waveone Gold、Protaper、Reciproc、MTwo和不锈钢K锉进行根管预备。比较五组根管预备效果及相关并发症、根管偏移量、根管充填效果。结果 五组根管预备时间比较,差异有统计学意义（P<0.05）,以Waveone Gold组根管预备时间最短;五组台阶形成发生率比较,差异有统计学意义（P<0.05）,五组根管侧穿、器械折断发生率比较,差异无统计学意义（P>0.05）。五组2mm、4mm及6mm垂直平面根管偏移量较小,差异有统计学意义（P<0.05）,以Waveone Gold组根管偏移量最小。五组超充率比较,差异无统计学意义（P>0.05）。五组恰充及欠充率比较,差异有统计学意义（P<0.05）,其中Waveone?Gold组、Reciproc组恰充率均高于对照组,欠充率均低于对照组（P<0.05）。结论 磨牙弯曲根管应用镍钛器械可缩短根管预备时间,相关并发症少、根管偏移量小、根管充填效果佳,尤以Waveone Gold具有明显优势。     

HIV感染者的自身抗体检测分析

目的分析人免疫缺陷病毒（HIV）感染者中出现的自身抗体和自身免疫现象。方法回顾性分析经间接免疫荧光法检测过自身抗体的HIV感染者的临床和相关实验室指标。结果共有19例HIV感染者检测了自身抗体,明确合并银屑病、溃疡性结肠炎、特发性血小板减少性紫癜（ITP）的患者各1例;8例出现风湿性症状,主要表现为原因不明的皮疹（5例）、关节疼痛（2例）和肌痛（1例）。10例自身抗体检测结果阳性,出现的自身抗体分别为抗核抗体（ANA）、抗平滑肌抗体（SMA）、抗线粒体抗体（AMA）、抗细胞骨架抗体（CS）、抗胃壁细胞抗体（AP—CA）。自身抗体阳性组患者的IgG和IgA水平明显高于自身抗体阴性组（P〈0．05）。结论HIV感染者中可检测出自身抗体,而且可以合并有自身免疫病或免疫亢进的现象。     

西罗莫司的作用机制及应用研究进展

西罗莫司是一种大环内酯类抗生素，为一种免疫抑制剂，结构与他克莫司(FK506)相似，但其作用机制却与神经钙蛋白阻滞剂类免疫抑制剂如环孢素A（CsA）和FK506等完全不同。近年来研究发现，它在抗移植排斥反应、抗肿瘤、预防支架植入术后再狭窄等方面均有作用。本文主要介绍了西罗莫司的作用机制及其应用的研究进展。     

抗乙醇脱氢酶抗体ELISA法的建立及其对自身免疫性肝炎诊断的价值

Objective To establish the enzyme-linked immunosorbent assay (ELISA) for the detection of serum alcohol dehydrogenase (ADH) antibody and evaluate its role in its diagnosis of autoimmune hepatitis( AIH ). Methods The reactivity between yeast ADH and human anti-ADH serum antibody was tested by Western blot analysis. ELISA was established using yeast ADH. The method was applied in serums of 67 AIH patients,94 primary biliary cirrhosis(PBC) patients, 199 chronic hepatitis B (CHB) patients, 132 chronic hepatitis(CHC) patients, 24 alcohol hepatitis disease(ALD) patients, 99 connective tissue disease(CTD) patients and 31 healthy individuals. The positive rate of ADH antibody in the patients and healthy individuals was measured. The χ2 test was used to compare the positive rates. Results The ELISA method for detecting human anti-ADH serum antibody was established successfully and the optimum reaction conditions were defined. Western blot showed that yeast ADH has cross reactivity with human anti-ADH antibody. The positive rate of anti-ADH antibody in the AIH group [59. 7% ,40/67 ] was higher than that in the normal control group(0,χ2 = 31. 271 ,P <0. 05), PBC group (6. 4% ,χ2 =54. 492,P <0. 05), CHB group( 14. 1% ,χ2 =54. 848,P <0. 05) ,CHC group(21.2% ,χ2 = 29.269,P<0.05), ALl) group ( 25. 0% ,χ2 =8.512,P <0.05)and CTD group ( 43. 4% ,χ2 =4.229, P <0. 05). Conclusions Compared with the PBC, CHB, CHC, ALD and CTD group, the anti-ADH antibody positive rate in the serums of AIH was significantly increased. The antibody may be helpful to the diagnosis of autoimmune hepatitis.
