The glomerular mesangial cell proliferation under different times and different concentrations were observed by MTT. Results The cell growth in blank group is the slowest at different time points. Compared with the control group, in the same culture conditions, GMCs proliferation stimulation in 0.4 g/L glucose group and 0.5 g/L glucose group at 48 h, 72 h were stronger (P<0.05,P<0.01), GMCs proliferation stimulating effect in 0.6 g/L glucose group, 0.7 g/L glucose group and 0.8 g/L glucose group at 24 h, 48 h, 72 h were stronger (P< 0.05, P <0.01), GMCs proliferation stimulating effect in 0.6 g/L glucose at 48 h, 72h were the strongest (P < 0.01). GMCs proliferation in high glucose group was more rapid than that in blank control group (P < 0. 05, P < 0.01). Compared with the high glucose group, GMCs proliferation in each group of containing Qiyaoxiaoke capsule serum at 48 h, 72 h was slow (P<0.05).

    • 摘要: Objective To study the effect of high glucose and lysophosphatidylcholine (LPC) on the role of fibronectin and plate-let activating factor (PAF) via the interaction of endothelial cells and mesangial cells. Methods The model of intercellular interaction be-tween endothelial cells and mesangial cells was established and divided into 4 groups: control, mannitol, high glucose and LPC, and BN52021 group. The level of fibronectin and PAF were determined by enzyme linked immunosorbent assay in the culture media. Results The level of fibronectin and PAF of high glucose and LPC group were higher than those of control group in co-culture and monolayer cell cul-ture (P<0.05). Intervened by high glucose and LPC, the level of fibronectin and PAF of co-culture were higher than those from monolay-er cell culture (P<0.05). The level of fibrocentin in the BN52021 group was lower than that of high glucose and LPC (P<0.05). Con-clusions Exposed to high glucose and LPC, endothelial cells and mesangial cells can interact with each other to produce more fibrocentin and PAF. The increase of fibronectin is partly concerned with PAF.%目的 探讨高糖高脂环境下内皮细胞与系膜细胞相互作用对纤维连接蛋白(Fn)产生的影响及PAF在内皮细胞与系膜细胞相互作用的地位.方法 内皮细胞与系膜细胞共培养和系膜细胞单独培养,分为对照组、甘露醇组、高糖高脂组、BN52021组,比较各组细胞上清液Fn、PAF含量.结果 高糖高脂促进共培养和单培养Fn和PAF升高(P<0.05);高糖高脂条件下,共培养组Fn和PAF均较单培养组升高(P<0.05),BN52021可抑制高糖高脂刺激的Fn升高(P<0.05).结论 高糖高脂条件下,系膜细胞和内皮细胞存在异常的相互作用,这种作用促进Fn、PAF产生,高糖高脂刺激的Fn分泌增加部分与PAF有关.

    • 摘要: Objective To explore the effect of angiotensin-(1-7) [Ang-(1-7)] on proliferation and secretion in cultured rat's glo-merular mesangial cells(GMC) induced by transforming growth factor-β1 (TGF-β1). Methods GMC in logarithmic growth phase were in-cubated, and then were divided into 4 groups: control, Ang-(1-7), TGF-β1,and TGF-β1 + Ang-(1-7) group. Cell numbers of rat's GMC were detected by WST-1. Laminin(LN) and collagenlV (ColⅣ) mRNA expressions in GMC were analyzed by RT-PCR. The secretion of LN and ColⅣ in culture medium of rat's GMC was measured by radioimmunoassay. Results Ang-(1-7) significantly inhibited basal and TGF-β1-induced proliferation of cultured glomerular mesangial cells. Ang-(1-7) significantly down-regulated LN and Col Ⅳ mRNA expressions in glomerular mesangial cells and also inhibited the secretion of LN and ColⅣ induced by TGF-β1(P <0. 05). Conclusions Ang-(1-7) can inhibit basal and TGF-β1-induced proliferation, and inhibit ECM secretion of cultured rats glomerular mesangial cells.%目的 探讨血管紧张素-(1-7)[Ang-(1-7)]时转化生长因子-β1(TGF-β1)诱导大鼠系膜细胞(GMC)增殖和细胞外基质分泌的影响.方法 选择对数生长期GMC,分为对照组、Ang-(1-7)组、TGF-β1组、TGF-β1+Ang-(1-7)组,采用WST-1检测系膜细胞增殖,RT-PCR法和放射免疫法检测细胞外基质层粘蛋白(LN)、Ⅳ型胶原(COL Ⅳ)的表达.结果 与对照组相比,Ang-(1-7)组细胞数目和细胞外基质减少(P<0.05);与TGF-β1组相比,Ang-(1-7)可抑制TGF-β1诱导的系膜细胞增殖、使细胞内LN mR-NA、COLⅣmRNA表达量明显下调、同时导致上清液中细胞外基质LN、COLⅣ含量显著减少(P<0.05).结论 Ang-(1-7)能抑制基础和TGF-β1诱导的GMC细胞增殖及细胞外基质的分泌,可能在抑制肾脏纤维化过程中发挥作用.

    • 摘要: Objective To investigate the effects of Lp(a)on proliferation GMCs of rat model induced by lipopolysaccharide and explore the possible mechanism of Lp(a)in the proliferation of rat GMCs.Methods To observe the effects of Lp(a)on proliferation of GMCs,different dosage of Lp(a)were used,The research were divided into three groups:Control group,LPS group,Lp(a)group.After culture(at the end of 12h,24h,48h,60h and 72h),the cultured GMCs and suspension were collected to observe the rate of GMCs proliferation by MTT,the positive rate of proliferation cell nuclear antigen(PCNA)by immunohistochemisty,and the level of intercellular adhesion molecule-1(ICAM-1)by ELISA respectively.Results Compared with control and LPS group,MTT,positive rate of PCNA and ICAM-1 of GMCs were increased more significantly in Lp(a)group.MTT ,the positive rate of PCNA and ICAM-1 of GMCs were increased as Lp(a)dosage increased,a maximal effect was seen when Lp(a)was 2.5 μg/L or 5.0μg/L.When the dosage continue increased,MTT,the positive rate of PCNA and ICAM-1 activity of GMCs began to decrease in Lp(a)group.ICAM-1 showed positive correlation with MTT and the positive rate of PCNA.Conclusion Lp(a)can significantly affect the rate of GMCs proliferation,and this affection is in a dosage-and timedependent manner.Low dosage stimulates GMCs proliferation, and high dosage inhibits GMCs proliferation.ICAM-1 shows positive correlation with MTT and the positive rate of PCNA.The effect of Lp(a)on GMCs may be through ICAM-1.%目的 探讨脂蛋白(a)[Lp(a)]对大鼠肾小球系膜细胞(GMCs)增生及细胞间黏附因子-1(ICAM-1)表达的影响.方法 分离Lp(a),培养GMCs,在不同时间(12、24、48、60、72 h),应用不同剂量(1.25 μg/L、2.5μg/L、5.0μg/L、10μg/L、20μg/L)Lp(a)处理GMCs,采用MTT法测定GMCs增生率,免疫组化法检测GMCs的增生细胞核抗原(PCNA)阳性表达率,酶联免疫法检测培养液上清的ICAM-1浓度,并与脂多糖组、对照组比较.结果 与LPS组、对照组比较,随着Lp(a)剂量的增加,GMCs的MTT、PCNA阳性表达率、上清ICAM-1浓度呈增加趋势,明显高于对照组,但低于LPS组,在Lp(a)2.5μg/L、5.0μg/L其作用达到高峰,大剂量时出现下降,剂量越大,下降越明显,Lp(a)10.0μg/L低于对照组,20.0μg/L则明显低于对照组.随着处理时间的延长,GMCs的MTT、PCNA阳性表达率、上清ICAM-1浓度呈增加趋势,但随着剂量的增加,依次于72、60、48 h逐渐出现下降.GMCs上清的ICAM-1浓度与MTT和PCNA阳性表达率呈正相关.结论 Lp(a)能明显影响GMCs的增生,作用呈剂量依赖性和时间依赖性,小剂量时刺激GMCs的增生,大剂量则表现为细胞毒作用.Lp(a)明显影响大鼠GMCs的ICAM-1表达,GMCs上清的ICAM-1浓度与MTT和PCNA阳性表达率呈正相关.提示Lp(a)对GMCs的作用可能与ICAM-1有关.
