动态监测血清、尿液和肾组织液中SIL－2R水平在肾移植早期的应用价值

为了了解可溶性白介素２受体（ＳＩＬ－２Ｒ）在肾移植早期的应用价值，动态监测４０例肾移植患者血清、尿液及肾组织液中可溶性白介素２受体水平变化，发现术前透析患者血清ＳＩＬ－２Ｒ水平较正常人高，术后迅速下降。急性排斥（ＡＲ）发生时，ＳＩＬ－２Ｒ水平均有不同程度的升高，以肾组织液中升高最明显，比临床症状和血清肌酐出现早１～５天。在急性ＣｓＡ中毒发生时血清和肾组织液中ＳＩＬ－２Ｒ水平明显升高，而急性感染发生时只在血清中明显升高。结果表明：动态监测血清、尿液ＳＩＬ－２Ｒ水平有助于预测和早期诊断ＡＲ，同时行肾组织液及血清、尿液ＳＩＬ－２Ｒ水平测定能较好地诊断与鉴别诊断ＡＲ、急性ＣｓＡ中毒和感染     

肾移植后血清白细胞介素2、可溶性白细胞介素2受体和白细胞介素6的监测

动态监测６０例肾移植患者术后２个月内血清白细胞介素２（ＩＬ－２）、可溶性ＩＬ－２受体（ｓＩＬ－２Ｒ）和白细胞介素６（ＩＬ－６）的变化。结果发现发生急性排斥反应时，上述细胞因子的升高较临床诊断提早数天，并且显著高于环孢素Ａ肾中毒组；对甲泼尼龙敏感的排斥反应，抗排斥治疗数天后上述因子下降到排斥前水平。提示肾移植术后动态监测患者血清ＩＬ－２、ｓＩＬ－２Ｒ和ＩＬ－６有助于急性排斥反应的早期诊断、鉴别诊断、及时治疗和甲泼尼龙抗排斥的疗效评价。     

肝移植后急性排斥反应的诊断和治疗

目的 探讨肝移植术后急性排斥反应的诊断和治疗。方法 １９９６年５月至１９９８年２月成功地进行了４例同种异体原位肝移植术,术前诊断：１例肝炎后肝硬变,３例肝豆状核变性。术后均采用环孢素Ａ,硫唑嘌呤和甲基泼尼松龙三联免疫抑制疗法。结果 ４例肝移植后共出现５次急性排斥反应。急性排斥反应时血清游离ＩＬ－２Ｒ明显升高,ＣＤ４／ＣＤ８比值减小,嗜酸性粒细胞增加,２例胆汁ＩＬ－２Ｒ也升高,而ＩＬ－６,ＩＬ－８,     

肾移植受者体内细胞因子及其受体的水平及意义

检测了７２例肾移植患者血中可溶性白细胞介素２受体（ＳＩＬ－２Ｒ）、肿瘤坏死因子（ＴＮＦ）及白细胞介素６（ＩＬ－６）的水平。结果发现，正常健康对照组ＳＩＬ－２Ｒ为１２５±５４ｋＵ／Ｌ，术后肾功能平稳组为２５６±９３ｋＵ／Ｌ，环孢素Ａ中毒组为３３８±７３ｋＵ／Ｌ，而ＴＮＦ在这几组中均测不出，ＩＬ－６均小于５ｋＵ／Ｌ。肾移植术后ＳＩＬ－２Ｒ迅速下降，与血肌酐有明显的一致性，ＩＬ－６水平升高，第２天达高峰（１８．２５±２．３６ｋＵ／Ｌ），以后逐渐下降，１０天后降至５ｋＵ／Ｌ。发生急性排斥反应组ＳＩＬ－２Ｒ为１０７７±４４８ｋＵ／Ｌ，升高较血肌酐提早２．２天，敏感性达９４．４％，特异性达９１．７％；ＩＬ－６为５９．９±３５．２７ｋＵ／Ｌ，并较临床症状出现平均提早１．２天；ＴＮＦ为３３．６７±１３．７μｇ／Ｌ，检出率为６７％。感染组的ＳＩＬ－２Ｒ、ＩＬ－６、ＴＮＦ分别为１６２０±３９７ｋＵ／Ｌ、７９．７５±６１ｋＵ／Ｌ及１２７．５±８３．８μｇ／Ｌ。结果表明，ＳＩＬ－２Ｒ、ＴＮＦ、ＩＬ－６可作为监测肾移植排斥反应的指标。     

同种异体肾移植患者血清SIL－2R水平变化及其临床意义

作者采用双抗体夹心酶联免疫吸附法（ＥＬＩＳＡ）对２０例同种异体尸肾移植患者进行了８９例次可溶性白介素２受体（ＳＩＬ－２Ｒ）检查。结果表明：移植前明显高于正常对照组，Ｐ＜０．００１。移植后随着肾功能的恢复而接近正常，但仍轻度高于正常对照组，Ｐ＜０．０１。发生急性排斥反应时较稳定期明显升高，Ｐ＜０．００１，且其上升时间早于血肌酐上升２～７天。而发生环孢素Ａ肾中毒或急性肾小管坏死时，血清ＳＩＬ－２Ｒ水平则变化不明显，Ｐ＜０．０５。因此，ＳＩＬ－２Ｒ的测定可作为移植肾排斥反应诊断和鉴别诊断的重要非创伤性指标。     

血清及尿白细胞介素-6检测在肾移植中的意义

目的探讨血、尿ＩＬ－６检测在肾移植急性排斥（ＡＲ）诊断及鉴别诊断中的作用。方法应用ＥＬＩＳＡ技术，分别对肾移植术后不同状态下患者血、尿ＩＬ－６水平进行检测。结果急性排斥及感染患者血ＩＬ－６水平较环孢素（ＣｓＡ）中毒、急性肾小管坏死（ＡＴＮ）、移植肾功能正常及正常对照组高。尿ＩＬ－６在急性排斥及感染组也较ＣｓＡ中毒、ＡＴＮ、移植肾功能正常组有明显升高，而急性排斥组较感染组升高更明显。结论血、尿ＩＬ－６水平的升高可作为判断肾移植急性排斥的指标之一；也可作为鉴别急性排斥反应与ＣｓＡ中毒、ＡＴＮ的重要参考指标；对鉴别急性排斥反应和感染具一定的参考价值     

脑胶质瘤患者血清sIL—2R水平变化的研究

应用双抗体夹心法１１３例Ｉ～Ⅳ级脑胶质瘤患者手术前后血清可溶性白细胞介素２受体（ｓＩＬ－２Ｒ）水平。结果发现胶质瘤患者术前血清ｓＩＬ－２Ｒ均高于正常对照组，其升高程度与肿瘤分级有明显关系（Ｐ〈０．０１），术后ｓＩＬ－２Ｒ均有不同程度下降，其中Ⅱ～Ⅳ级者下降尤为明显（Ｐ〈０．０１），术后ｓＩＬ－２Ｒ再次升高可先于肿瘤复发；血清ｓＩＬ－２Ｒ与脑脊液（ＣＳＦ）及肿瘤囊液中ｓＩＬ－２Ｒ均呈正相关。提示血清     

慢性肾功能衰竭患者血清及尿白细胞介素—8的检测及意义

目的 了解慢性肾功能衰竭（ＣＲＦ）患者血清及尿ＩＬ－８水平的变化及意义。方法 双抗体夹心ＥＬＩＳＡ法。结果 ＣＲＦ患者血清及尿中ＩＬ－８的含量均显著高于正常对照组（Ｐ〈０．００１），但与Ｓｃｒ无明显相关性（ｒ＝－０．２７，Ｐ〉０．０５和ｒ＝－０．０５，Ｐ〉０．０５）。结论 ＣＲＦ仍存在比较严重的免疫炎症反应，此可能为肾小球功能受损的重要原因之一。     

监测肾移植术后IL－2和sIL－2R的变化及其意义

对７２例肾移植患者术后血清ＩＬ－２和ｓＩＬ－２Ｒ进行检测，分析移植术后ＩＬ－２和ｓＩＬ－２Ｒ的变化规律，发现在急性排斥和继发感染时，患者血中ＩＬ－２和ｓＩＬ－２Ｒ含量均明显升高．认为监测肾移植术后ＩＬ－２和ｓＩＬ－２Ｒ的变化有助于了解免疫抑制水平和体内免疫系统的功能状态，并可早期诊断急性排斥和继发感染．

基于慢病毒的SHARP-2特异的RNA干扰延长肾移植受者大鼠存活时间

Objective To investigate if rat enhancer of split- and hairy-related protein-2 (SHARP-2) short hairpin RNA interference (shRNAi) prolongs the survival time of rat kidney transplant recipients. Methods Gene recombinant procedures, transfection and co-transfection were carried out to introduce short hairpin RNA interference sequences target for SHARP-2 into 3rd generation self-inactivated lentiviral-ViraPower packaging mix. Limiting dilution method was used for viral titration. Real-time PCR was employed for quantification of gene expression. Rat kidney transplantation was utilized to investigate the effect of SHARP-2 gene silence on the recipient survival. Results A lentiviral-based shRNAi construct LV-SHARP-2iC showed 84% SHARP-2 gene silence efficiency in normal rat kidney cells. At multiplicity of infection 20, 57% T cells could be transfected by lentivirus with spinoculation method. In activated T cells, SHARP-2 g ene silence resulted in 61.3% and 68.7% reduction of intedeukin 2 (IL-2) and interferon γ (IFN-γ) gene expression. When donor kidney was perfused with 5×107 TU LV-SHARP-2iC, the median survival time prolonged for 4-5 days as compared to blank and scramble control groups. Conclusions A recombinant lentivirus LV-SHARP-2iC that effectively silence SHARP-2 gene expression is constructed successfully, leading to the inhibition of IL-2 and IFN-γ. LV-SHARP-2iC treatment can prolong the survival time of rat kidney transplant recipients.
