To observe the effects of acupuncture-moxibustion on chronic allograft nephropathy (CAN) and explore the methods of acupoint selection along meridian for transplanted-kidney-related diseases.
A total of 180 patients of CAN were randomized into a syndrome differentiation group, a spleen-meridian group, a kidney-meridian group and a control group, 45 cases in each one. A total of 33 cases dropped out before the end of the study, including 8 cases in the syndrome differentiation group, 12 cases in the spleen-meridian group, 13 cases in the kidney-meridian group and no case in the control group. Patients in the control group were treated with conventional western medicine; based on this, patients in other three groups were treated with acupuncture-moxibustion. In the syndrome differentiation group, Qihai (CV 6), Hegu (LI 4), Guanyuan (CV 4), Feishu (BL 13), Shenshu (BL 23), etc. were selected for qi deficiency of lung and kidney; Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), etc. were selected for deficiency of qi and yin; Ganshu (BL 18), Shenshu (BL 23), Sanyinjiao (SP 6), Taixi (KI 3), Yinlingquan (SP 9), Ququan (LR 8), etc. were selected for yin deficiency of liver and kidney; Zhongji (CV 3), Guanyuan (CV 4), Mingmen (GV 4), Guanyuanshu (BL 26), etc. were selected for yang deficiency of spleen and kidney. In addition, Sanyinjiao (SP 6), Diji (SP 8), Yinlingquan (SP 9), Xuehai (SP 10), etc. were added in the spleen-meridian group; Taixi (KI 3), Zhaohai (KI 6), Fuliu (KI 7), Ciliao (BL 32), etc: were added in the kidney-meridian group. Serum creatinine (Scr), creatinine clearance (Ccr) and 24-hour urinary protein before and after the treatment were com- pared among the four groups.
After treatment, 24-hour urinary protein in the acupuncture-moxibustion groups and control group were all reduced (all P < 0.05); compared before treatment, the Scr in the spleen-meridian group was significantly reduced (P < 0.05); the difference of Ccr before and after treatment was insignificant in all the groups (all P > 0.05). Compared with the control group, 24-hour urinary protein in spleen-meridian group could relieve or recover the damage of transplant kidney induced by CAN. A new interlink may be established between the transplanted kidneys and the spleen meridians, indicating that transplanted kidney-related diseases can be treated by selecting acupoints of spleen meridian.
