RESUMO

<p><b>OBJECTIVE</b>To observe the effects of Qufengtongluo Recipe (QFTLR) on the expressions of cell cycle regulatory proteins in rat mesangial cells (MCs) in vitro and investigate the mechanism by which QFTLR inhibits MC proliferation.</p><p><b>METHODS</b>Using the methods of serum pharmacology, we studied the expressions of cell cycle regulatory proteins in rat MCs treated with QFTLR by laser scanning confocal microscope and immunohistochemistry.</p><p><b>RESULTS</b>Compared with the normal control cells, the cells challenged with lipopolysaccharide (LPS) showed significantly enhanced expressions of cyclin D1, CDK2, and P21 (P<0.01) and obviously lowered protein expression of P27 (P<0.01). Treatment of the LPS-challenged cells with QFTLR and benazepril both resulted in significantly attenuated expressions of cyclin D1, CDK2, and P21 and obvious increase of P27 expression (P<0.05 or P<0.01), but QFTLR produced stronger effects than benazepril in regulating of cyclinD1, P21 and P27 protein expressions (P<0.05 or P<0.01).</p><p><b>CONCLUSION</b>QFTLR inhibits rat MC proliferation in vitro possibly by down-regulating the cellular expressions of cyclin D1, CDK2, and P21 and up-regulating the expression of P27 protein.</p>

RESUMO

Objective To explore the effects of Yishen Capsule on the soluble endothelium protein C receptor (sEPCR) and P-selectin (CD62P) as well as the serum levels of immunoglobulin (Ig) and complement 3 (C3) in patients with chronic glomerulonephritis (CGN). Methods The changes of sEPCR and CD62P levels in plasma as well as Ig and C3 levels in serum were assessed in 40 normal subjects and 78 patients before and after treatment by double-antibody enzyme-linked immunosorbent assay, flow cytometry and immunoturbidimetry, respectively. Results Compared with those in normal group before treatment, the levels of sEPCR and CD62P in plasma as well as IgA in serum increased obviously (P<0.01), and the levels of IgG and IgM as well as C3 in serum decreased significantly in CGN patients (P<0.01). After three months' treatment with Yishen Capsule, the levels of sEPCR and CD62P in plasma and IgA in serum decreased significantly (P<0.05 or P<0.01), and the levels of IgG and IgM in plasma as well as C3 in serum increased obviously (P<0.05 or P<0.01). Conclusion The mechanism of Yishen Capsule's effect in treating patients with CGN may be correlated with decreasing sEPCR and CD62P levels in plasma as well as regulating the levels of Ig in serum and C3.
