RESUMO
OBJECTIVE: To compare the curative effects of primary osteoporosis treated with heat-sensitive point moxibustion and Gaitianli (Oyster Shell and Calcium Carbonate Chewable) tablets for oral administration and explore the treatment mechanism. METHODS: Sixty cases of primary osteoporosis were randomly divided into a heat-sensitive point moxibustion group (moxibustion group) and a Gaitianli tablets group (medication group), 30 cases in each group. In the moxibustion group, the heat sensitized points were searched around Zusanli (ST 36), Pishu (BL 20), Shenshu (BL 23) and Mingmen (GV 4) and treated by heat-sensitive point moxibustion; in medication group, Gaitianli tablets were taken by oral administration, 3 pills for once and 3 times a day. The curative effects, bone mineral density (BMD), alkaline phosphatase (S-AKP) and urinary calcium to creatinine ratio (U-Ca/Cr) in both groups were observed before and after treatment. RESULTS: The total effective rate was 86.7% (26/30) in moxibustion group, superior to that of 76.7% (23/30) in medication group (P < 0.05). After treatment, the BMD of lumbar vertebrae (L2-L4) mean was improved (P < 0.05), and the S-AKP and U-Ca/Cr were reduced (all P < 0.05); in medi cation group, the indexes above were no obvious changes (all P > 0.05). CONCLUSION: The therapeutic effect of primary osteoporosis treated with heat-sensitive point moxibustion is superior to that with Gaitianli tablets for oral administration. The mechanism is restraining bone resorption, increasing bone strength, keeping balance of bone metabolism, in order to increase bone mineral density and improve the clinical symptoms.
