    • 摘要: 目的探讨血中性粒细胞明胶酶相关脂质运载蛋白(NGAL)、尿NGAL、血清胱抑素C(Cys-C以及血清肌酐(Scr)预测肾移植受者发生肾功能延迟恢复(DGF)的价值。方法收集159肾移植受者的临床资料及血液、尿液标本,根据是否发生DGF,分为DGF组(42例)和即刻肾功能恢复(IGF)组(117例)。分析两组受者的临床资料,对比两组受者的血NGAL、尿NGAL、Cys-C及Scr变化情况,分析不同指标对DGF的早期预测价值。结果159例肾移植受者中,42例发生DGF,发生率为26.4%。两组供者年龄、供肾冷缺血时间及补体依赖淋巴细胞毒性试验(CDC)比较,差异有统计学意义(均为P<0.05)。DGF组血NGAL在术后2周内均高于IGF组(均为P<0.05);DGF组Cys-C、Scr、尿NGAL在术后3周内均高于IGF组(均为P<0.001)。血NGAL、尿NGAL、Cys-C和Scr对肾移植受者发生DGF具有一定预测价值,其中Cys-C预测价值最高,截取值为4.73 mg/L,灵敏度为0.833,特异度为0.812,曲线下面积(AUC)为0.895。结论Cys-C早期预测肾移植受者发生DGF的价值高于血NGAL、尿NGAL及Scr。

    • 摘要: 微小病变肾病(minimal change disease,MCD)是原发性肾病综合征中最常见的病理类型之一,尤其好发于儿童及青少年.肾病综合征患者容易合并一系列并发症,如感染、静脉血栓栓塞、急性肾损伤(acute kidney injury,AKI)等.近年来肾病综合征合并AKI的发病率明显上升,其中以MCD合并AKI最为常见.MCD合并AKI会致使患者病情加重,增加临床治疗难度,并与肾脏不良预后密切相关.MCD合并发生AKI的机制涉及多种不同途径,常见的包括有效循环血容量下降导致的肾小球滤过率下降,肾血管病变带来的肾单位缺血,以及蛋白尿对肾小管的直接毒性作用,等等.本文回顾近年来有关MCD合并AKI领域的临床和基础研究,对其发病率、病理生理学机制、早期的诊断指标和防治原则进行综述,旨在提高临床对MCD合并AKI的认识和诊疗水平.

    • 摘要: 目的 观察Necrostatin-1(坏死性凋亡特异性抑制剂,Nec-1)对急性肾小管坏死(ATN)大鼠的保护作用,并对其作用机制进行分析.方法 选取45只SD雄性大鼠,采用肌肉注射甘油的方法制作ATN动物模型,随机分为Nec-1低剂量组、Nec-1高剂量组和模型组,每组15只;另选15只大鼠作为对照组.Nec-1低剂量组和高剂量组大鼠分别给予0.4 mg/kg和0.8 mg/kg Nec-1(二甲基亚砜溶解)尾静脉注射,模型组和对照组注射等体积二甲基亚砜.分别对各组大鼠血肌酐(Scr)、血尿素氮(BUN)和肾功能衰竭指数(RFI)进行分析;采用ELISA法检测各组大鼠肾脏组织中肿瘤坏死因子-α (TNF-α)和白细胞介素-1β(IL-1β)水平;采用Western blot方法检测受体相互作用蛋白1和3(RIP1,RIP3)的表达;苏木精伊红(HE)染色观察分析肾脏组织病理学变化.结果 与对照组比较,模型组、Nec-1低剂量组和高剂量组大鼠Scr水平、BUN水平以及RFI显著升高(P<0.05),肾脏组织中TNF-α、IL-1β、RIP1以及RIP3水平显著升高(P<0.05).与模型组大鼠比较,Nec-1低剂量组和高剂量组大鼠Scr水平、BUN水平以及RFI显著下降(P<0.05),肾脏组织中TNF-α、IL-1β、RIP1以及RIP3水平显著下降(P<0.05).病理结果显示,与对照组比较,模型组、Nec-1低剂量组和高剂量组大鼠肾脏均不同程度增大,肾小管变形明显,管腔中蛋白管型增多,且模型组大鼠病理变化较Nec-1低剂量组和高剂量组显著(P<0.05);其中,低剂量和高剂量组大鼠各项指标的变化均呈剂量依赖性.结论 Necrostatin-1能够有效改善急性肾小管坏死大鼠Scr、BUN水平及RFI,起到保护肾脏损伤的作用,其机制可能与抑制体内炎症因子水平和细胞程序性坏死相关.%Objective To observe the protective effect of Necrostatin-1 on acute tubular necrosis (ATN) rats,and to analyze the mechanism.Methods Forty-five SD male rats were enrolled to prepare ATN aninal model by intramuscular injection of glycerol production,and they were randomly divided into model group,low dose group and high dose group,with 15 rats in each group.Fifteen normal rats were selected as control group.Rats in low dose group and high dose group were given 0.4 mg/kg and 0.8 mg/kg Nec-1 (dissolved in DMSO) by tail vein.Rats in model group and control group were injected with equal DMSO.Serum creatinine (Scr),blood urea nitrogen (BUN) and renal failure index (RFI) were analyzed.Tumor necrosis factor alpha (TNF-α) and interleukin-1 β (IL-1 β) levels in peripheral blood were detected by ELISA method.Receptor interacting protein 1 (RIP1) and receptor interacting protein 3 (RIP3) were detected by Western blot.Pathological changes of kidney were observed and analyzed by HE stain.Results Compared with control group,Scr level,BUN level and RFI of rats in model group,low dose group and high dose group were increased significantly (P < 0.05),TNF-α,IL-1 β,RIP1 and RIP3 levels in kidney tissues of rats were increased significantly (P < 0.05).Compared with model group,Scr level,BUN level and RFI of rats in low dose group and high dose group were decreased significantly (P < 0.05),TNF-α,IL-1 β,RIP1 and RIP3 levels in kidney tissues of rats were decreased significantly (P < 0.05).Compared with control group,pathological results showed that the kidney grew in varying degrees,renal tubular deformed obviously,protein tube type in lumen increased in model group,low dose group and high dose group.The pathological change of rats in model group were more significant than that of low dose group and high dose group (P < 0.05).The changes of each index of the low dose and high dose group were dose dependent.Conclusions Necrostatin-1 can effectively improve Scr,BUN level and RFI of rats with acute renal tubular necrosis.It plays a role in protecting the kidney with the mechanism of the inhibition of the levels of inflammatory factors and programmed cell necrosis.

    • 摘要: Objective To investigate the value of diffusion-tensor imaging(DTI) and blood oxygen level-dependent(BOLD) in differentiation acute rejection(AR) and acute tubular necrosis(ATN), and to explore a sensitive, noninvasive strategy of evaluating renal allograft function.Methods A total of51 renal allograft recipients at2-3 weeks after transplantation in Tianjin First Center Hospital were included in this study from May2012 to March2014 and they were examined using a fat-saturated echo-planar DTI and GRE-BOLD sequence in oblique-coronal orientation at3.0 Tesla magnetic resonance(MR) imager(diffusion directions=6,b=0.300 s/mm2). All patients were divided into three groups: normal renal function group, acute rejection group and acute tubular necrosis group, and the AR and ATN groups were confirmed by pathological biopsy. Mean apparent diffusion coefficient(ADC) and mean fractional anisotropy(FA) and apparent spin-spin relaxation rate(R2*) values of the cortex and medulla were determined separately and comparisons of parameters between the3 groups were tested by one-way ANOVA analysis. Meanwhile, the receiver operating characteristic(ROC) curves was used to compare the differential diagnostic efficacies of every parameters in AR group and ATN group for determine the best diagnostic threshold.Results Compared with normal group, mean ADC value in cortex, mean ADC value in medulla and medullary R2* value of AR group were significantly lower〔mean ADC value in cortex(×10-3mm2/s):2.31±0.49 vs. 2.85±0.28, mean ADC value in medullar(×10-3mm2/s):2.21±0.50 vs.3.07±0.38,medullary R2* value(1/s):19.5±3.3 vs.22.7±3.3,allP0.05). ROC curves revealed that the cut-off values of cortical ADC, medullary ADC and medullary R2* in differentiation AR and ATN were 2.68×10-3 mm2/s,2.73×10-3 mm2/s and21.4/s respectively. Both sensitivity and specificity were higher than70%. The three parameters had comparable power in differentiating ATN and AR allografts(P>0.05).Conclusion DTI and BOLD can identify transplanted renal AR and ATN noninvasively, and mean R2* value in the medulla, mean ADC value in the cortex and medulla can be used as index for differentiating.%目的:探讨扩散张量成像(DTI)、血氧水平依赖成像(BOLD)对移植肾急性排异反应(AR)和急性肾小管坏死(ATN)鉴别诊断价值,以期探寻无创、敏感的评价移植肾功能的方法。方法选取2012年5月—2014年3月在天津市第一中心医院进行异体肾移植术后2~3周的患者51例纳入本研究,所有受试者均于Siemens MAGNETOM Trio Tim3.0T超导磁共振扫描仪进行常规磁共振成像(MR)及脂肪抑制平面回波斜冠状面DTI检查(在6个非共线性方向上施加扩散敏感梯度场,b值为0.300 s/mm2)及斜冠状面BOLD检查。患者分为三组:移植肾功能正常组、AR组及ATN组,其中AR组与ATN组均经病理穿刺证实。分别测量并计算各组移植肾皮质、髓质的表观扩散系数(ADC)值、各向异性分数(FA)值及表观自旋-自旋弛豫率(R2*)值,采用单因素方差分析比较移植肾各组间各参数值的差异。采用受试者工作特征曲线(ROC)比较皮髓质ADC值及R2*值对AR组以及ATN组的鉴别诊断效能并确定最佳诊断阈值。结果与正常组相比,AR组皮质ADC值、髓质ADC值、R2*值显著下降〔皮质ADC值(×10-3mm2/s):2.31±0.49比2.85±0.28,髓质ADC值(×10-3mm2/s):2.21±0.50比3.07±0.38,R2*值(1/s):19.5±3.3比22.7±3.3,均P<0.05〕。与ATN相比,AR组皮质ADC值、髓质ADC值、R2*值显著下降〔皮质ADC值(×10-3mm2/s):2.31±0.49比2.85±0.27,髓质ADC值(×10-3mm2/s):2.21±0.50比2.76±0.35, R2*值(1/s):19.5±3.3比23.6±2.8,均P<0.05〕;三组之间皮质、髓质FA值及皮质R2*值均无明显差异(P>0.05)。皮质ADC值、髓质ADC值及髓质R2*值对AR组与ATN组鉴别的最佳诊断阈值分别为2.68×10-3mm2/s、2.73×10-3mm2/s、21.4/s,其敏感性和特异性均在70%以上,鉴别诊断效能均无明显统计学差异(P>0.05)。结论 DTI、BOLD能无创、有效鉴别移植肾AR与ATN,其中皮髓质ADC值及髓质R2*值可作为鉴别诊断指标。
