Objective To investigate the effect of Niaoduqing Particles on the microinflammatory state in patients with maintenance hemodialysis. Methods Totally 240 patients with hemodialysis for more than 6 months were randomly divided into conventional hemodialysis group, Chinese medicine group (treated with Niaoduqing Particles) and western medicine group (treated with Vitamin E), 80 cases in each group, with 30 healthy people as control group. The levels of hs-CRP, IL-6 and HCY were detected before and after 1, 3, 6 months of treatment. Results Before treatment, the levels of inflammatory factors in hemodialysis patients were higher than control group. And after 3 months of treatment, the levels of hs-CRP, IL-6 and HCY of Chinese medicine group were decreased. And after 6 months of treatment, the levels of inflammatory factors were decreased obviously compared with pretherapy (P<0.01), and the difference with the conventional hemodialysis group was significant (P<0.01). Compared with pretherapy, the changes of inflammatory factors of western medicine group were statistically insignificant. Conclusion Niaoduqing Particles can significantly improve the microinflammatory state in maintenance hemodialysis patients, and the effect is superior to Vitamin E.
