ABSTRACT
Objective To observe the effect of Qingshen Granule (QG) on expressions of nucle- ar factors-κB p65 (NF-κB p65) and phosphonated inhibitor of nuclear factor-κB (p-lκBα) in peripheral blood NF-κB signal transduction pathway of chronic renal failure (CRF) patients with damp-heat syn- drome (DHS) , and to study possible mechanism. Methods Totally 68 CRF patients with DHS were as- signed to the control group and the treatment group by random digit table, 34 in each group. Actually 63 patients completed, 32 in the treatment group and 31 in the control group. A normal group (20 cases) was set up. All patients received basic treatment of Western medicine (WM) and retention enema of Chi- nese medicine (CM). Patients in the treatment group additionally took QG, 1 package each time, 3 times per day. The therapeutic course for all was 8 weeks. The clinical efficacy, level of serum creatinine (SCr), estimated glomerular filtration rate (eGFR), the levels of NF-κB p65 and p-IκBα in peripheral blood were observed and measured before and after treatment. They were also compared with those of the normal group. Results The clinical efficacy and the total effective rate of CM syndrome were 84. 38% (27/32)and 81. 25% (26/32), superior to those of the control group [54. 84%(17/31), 51. 61% (1631) ; P <0. 01 ]. Compared with before treatment, the level of SCr was obviously lower, and eGFR was obviously higher in the treatment group after treatment (P <0. 01). They were better than those of the control group after treatment (P <0. 05). Compared with the normal group, the levels of NF-κB p65 and p-IκBα were significantly higher in the treatment group and the control group before treatment (P < 0. 01). Compared with before treatment, the levels of NF-κB p65 and p-IκBα were obviously lowered in the treatment group after treatment (P <0. 01). They were also better than those of the control group after treatment (P <0. 05). Conclusions QG could improve clinical symptoms of CRF patients with DHS, de- crease SCr level, and increase eGFR level. It could protect renal function. Its mechanism might possibly be related with reducing peripheral blood levels of NF-κB p65 and p-IκBα.
