OBJECTIVETo compare the effect on erythropoietin (Epo) resistance between acupoint injection and subcutaneous injection of rHuEpo in patients with chronic renal failure (CRF).

METHODSThirty-eight cases were randomly divided into two groups, 19 cases in each one. In subcutaneous injection group (control group), subcutaneous injection of rHuEpo was administered, 3 times a week, lasting 2 months. In acupoint group (observation group), rHuEpo was injected on unilateral Shenshu (BL 23) and Zusanli (ST 36), one point was chosen each time, the bilateral acupoints were injected alternatively, 3 times a week, for 2 months. Meanwhile, a normal control group of 19 healthy persons was set up. The levels of CRP, IL-6, TNF-alpha, Scr, BUN, Hb, Hct and SF were observed.

RESULTSBefore treatment, the values of CRP, IL-6 and TNF-alpha in two groups were all higher than those in normal control group (all P < 0.01). After treatment for 2 months, the values of CRP, IL-6,TNF-alpha, Scr and BUN in two groups decreased apparently and those of Hb, Hct and SF increased obviously, indicating statistic significant differences as compared with the values before treatment separately (P < 0.05, P < 0.01). In comparison between two groups after treatment, every index above in observation group was improved much significantly (P < 0.05, P < 0.01).

CONCLUSIONAcupoint injection of rHuEpo at Zusanli (ST 36) and Shenshu (BL 23) increases significantly the values of Hb, Hct and SF, and decreases apparently the values of BUN, Scr and inflammatory factors, such as CRP, IL-6 and TNF-alpha as compared with subcutaneous injection. Acupoint injection improves Epo resistance and enhances Epo efficacy via alleviating micro-inflammatory state of the body.
