血清和糖皮质激素诱导蛋白激酶1在糖尿病大鼠肾脏的表达及氟伐他汀的调节作用

血清和糖皮质激素诱导的蛋白激酶（SGK）是丝氨酸／苏氨酸蛋白激酶家族的一个新成员。Lang等发现TGF-β1和体外高糖明显影响纤维母细胞中hSGK的转录水平，进一步提出hSGK是TGF-β1发挥作用的下游靶分子。现已证实，CTGF是TGF-β1介导的肾间质纤维化的重要下游效应因子。经检索，有关CTGF与SGK1的关系未见报道。本研究旨在探讨SGK1介导的信号转导通路在糖尿病肾病发生、发展中的作用．并观察氟伐他汀对其的调节作用。     

精氨酸-甘氨酸-天门冬氨酸肽在急性肾衰中的潜在治疗作用

精氨酸－甘氨酸－天门冬氨酸三肽（ＲＧＤ）是整合素受体与细胞外基质配体或基膜成份配体相结合的识别位点，在急性缺血性肾衰时可抑制肾小管上皮细胞之间的粘附，从而预防肾小管阻塞，改善急性肾衰预后，具有潜在的临床应用价值。本文综述了急性肾衰时整合素受体分布异常及其病理生理学意义，ＲＧＤ肽结合位点的组织分布，ＲＧＤ肽对急性肾衰的潜在治疗作用。     

Beagle犬血液细胞及生化值测定与比较

为了给Beagle犬的推广应用提供更多的正常背景资料，用ADVIA试剂及分析仪检测了168只成年、健康Beagle犬的血液学与血液生化指标值。共检测15个项目，并将其中的13个项目的平均值同20年前检测结果比较。结果发现，其中6项指标的差别有显著性，因此建议对Beagle犬的生理生化正常值应定期复查，尤其是在饲养、繁育条件有变化时。     

蛋白酶激活受体2在小鼠肾间质纤维化中的表达及其意义

目的 观察单侧输尿管梗阻(UUO)小鼠模型中蛋白酶激活受体2(PAR-2)在肾小管间质中的表达部位、动态变化及其与肾间质纤维化的关系。方法 制备UUO小鼠模型,采用RT-PCR方法检测UUO术后第1、3、5、7、10、14、21天肾组织中PAR-2mRNA的表达;免疫组化方法检测PAR-2蛋白的表达。分析它与肾间质相对面积、α-平滑肌肌动蛋白(SMA)表达水平的关系。结果 UUO术后第1天肾小管间质可见少量PAR-2mRNA和蛋白的表达,第7-14天表达显著增加,其后维持在较高水平。PAR-2表达量与肾间质相对面积、α-SMA表达量成正相关。PAR-2表达主要定位于肾小管上皮细胞(尤其为近曲小管),也可见于肾毛细血管袢、间质浸润细胞和成纤维细胞。结论 PAR-2在肾小管上皮细胞和肾间质的表达可能参与了肾间质纤维化发生发展的过程。     

不同形式补铁对尿毒症血液透析患者生活质量的影响

尿毒症是常见的慢性病。随着肾脏替代疗法的发展 ,尿毒症患者的生存时间已明显延长 ,但生活质量却仍然很低。近年 ,给尿毒症血液透析患者静脉补铁已成为国外研究的热点 ,借鉴他们的经验 ,我们给一部分尿毒症血透患者进行了静脉补铁 ,并从贫血、缺铁的改善和生活质量的提高两个方面对其疗效作了客观评价。国内迄今鲜见类似报道。本文着重介绍两种不同形式补铁对生活质量的影响。材料与方法一、病例选择1 .入选标准　从本中心 98名维持性血液透析 (ｈｅｍｏｄｉａｌｙ ｓｉｓ,ＨＤ)患者中选取符合下述条件的病例 :(1 )规律ＨＤ至少稳定 3个月 …     

罗格列酮抑制大鼠肾间质纤维化的实验研究

目的：探讨过氧化物酶体增生物激活受体-γ激动剂——罗格列酮对单侧输尿管梗阻(UUO)大鼠。肾间质纤维化的影响。方法：将30只wistar大鼠随机分成罗格列酮治疗组、模型组和假手术组。对治疗组，模型组行单侧输尿管结扎术建立输尿管梗阻的动物模型。术后第21天取3组术侧。肾组织做HE和Masson三色病理染色及用免疫组化方法检测α-平滑肌肌动蛋白(α-SMA)、转化生长因子-β1(TGF-β1)和Ⅰ型胶原(ColⅠ)在肾组织的表达水平。结果：罗格列酮可显著下调α-SMA、TGF—β1的表达．减轻Ⅰ型胶原在肾间质中的沉积，改善了肾脏病理改变。结论：罗格列酮对UUO所致的肾间质纤维化的形成有抑制作用。

The Effect of Connective Tissue Growth Factor on Human Renal Tubular Epithelial Cell Transdifferentiation

Summary To investigate the role of connective tissue growth factor (CTGF) in transdifferentiation of human renal tubular epithelial cell (HKC),in vitro cultured HKC cells were divided into 3 groups: negtive control, low dose CTGF-treated group (rh CTGF, 2.5 ng/ml) and high dose CTGF-treated (rhCTGF, 5. 0 ng/ml). Then the expression of α-smooth muscle actin (α-SMA) were assessed by indirect immuno-fluorescence, and the percentage of α-SMA positive cells were assessed by flow cytometry. RT-PCR were also performed to examine the mRNA level of α-SMA. Upon the stimulation of different concentrations of rhCTGF, the expression of α-SMA were markedly stronger than that in negative controls. The percentages of α-SMA positive cells were significantly higher in the stimulated groups than that of negative controls (38.9%, 65.5% vs 2.4%,P<0.01). α-SMA mRNA levels were also up-regulated by the stimulation of rhCTGF (P<0.01). These results suggest that CTGF can promote the transdifferentiation of human renal tubular epithelial cells towards myofibroblast (Myo-F). ZHANG Chun, male, born in 1977, M. D., Ph. D.

Effect of Two Different Iron Supplementation on the Quality of Life of Uremic Hemodialysis Patients

UREMIC RENAL FAILURE is a common chronicdisease. Hemodialysis therapy has increased thelifespan of uremic patients significantly. Patientquality of life (QL), however, is also an importantindicator of the effectiveness of the medical carethat patients receive and therapies that prolonglifespan may actually compromise quality of life.1In recent years, intravenous iron has been studiedas an adjunctive therapy for anemia in hemodialysispatients. Based on protocols published previously,we selected hemodialysis ...
