Objective: To follow up the participants of the randomized clinical trial "Efficacy and Safety of niaoduqing Particles(尿毒清颗粒) for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of niaoduqing Particles on delaying the progression of renal dysfunction. Methods: Participants, who had previously been randomly assigned to receive niaoduqing Particles or placebo for 24 weeks(146 cases in each group), were invited to follow-up and all were administered niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine(Scr) and estimated glomerular filtration rate(e GFR) after completion of the open-label treatment period. Results: After the double-blind period, the median(interquartile range) changes in Scr were 1.1(–13.0–24.1) and 11.7(–2.6–42.9) μmol/L for the niaoduqing Particle and placebo groups, respectively(P=0.008), and the median changes in e GFRs were –0.2(–4.3–2.7) and –2.21(–5.7–0.8) mL·min^(-1)·1.73 m^(-2), respectively(P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0(–10.0–41.9) and 17.5(–6.0–50.0) μmol/L for the niaoduqing Particle and placebo groups according to baseline grouping, respectively(P=0.214), and the median changes in eGFRs were –2.3(–6.4–1.9) and –3.7(–7.5–1.1) mL·min^(-1)·1.73 m^(-2), respectively(P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted niaoduqing Particle treatment for 48 weeks was projected to 2.5 m L·min^(-1)·1.73 m(-2) per year. Conclusions: niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of niaoduqing Paticles seems to ameliorate the worsening of renal function.

in the advanced stage of kidney diseases,the functional capacity of the diseased kidney gradually declines , and develops into uremia. There is no medicine to retard the progression of early stage chronic renal failure to end-stage renal failure. For this reason, a clinical study was performed in two groups of patients with early stage chronic renal failure. Group 1 patients (400 cases) were treated with a herbal preparation, niaoduqing,and group 2 patients (160 cases) received therapy with Oxyamyli Tectus Sldehydum. It was found that both blood urea nitrogen (BUN) and serum creatinine (Scr) levels decreased in group 1 patients (P0. 05).According to theory of traditional Chinese medicine , niaoduqing can clear BUN and Scr . ameliorate uremic symptoms and protect the residual renal function. From the study, it is suggested that this herbal mixture can be used to treat patients with moderate renal failure. Furthermore , the mixture can be conveniently taken orally and has no side effects.
