[Drinking-water type fluorosis treated with acupuncture of reinforcing kidney and activating spleen: a randomized controlled trial].

ABSTRACT

OBJECTIVE: To observe the impacts of acupuncture of reinforcing kidney and activating spleen on the excretion of urinary fluoride and pain of the patients with drinking-water type fluorosis. METHODS: The randomized controlled and single-blind trial was adopted. Seventy-two cases were randomized into an observation group and a control group, 36 cases in each one. In the observation group, acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuan (CV 4), Zusanli (ST 36), etc. , three treatments a week. In the control group, the Calcium Carbonate D3 tablets were prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months. The changes of the content of urinary fluoride and pain score (by VAS) before and after treatment between two groups were compared. RESULTS: The urinary fluoride excretion was increased obviously after treatment in the observation group (P < 0.01), which was superior apparently to that in the control group [(11.06 +/- 4.54) mg/L vs. (8.30 +/- 4.14) mg/L, P < 0.05]. After treatment, VAS score was reduced significantly in either group (both P < 0.01). The result in the observation group was lower remarkably than that in the control group (1.93 +/- 1.30 vs. 3.47 +/- 2.29, P < 0.01). CONCLUSION: Acupuncture achieves the significant efficacy on the promotion of urinary fluoride excretion and pain relieving of the patients with drinking-water type fluorosis in light of reinforcing kidney and activating spleen, which is superior to the oral administration of the calcium carbonate D3 tablets.
