[Inner-heating acupuncture of lumbar degenerative lesions based on β-catenin signaling pathway]

By observing the effect of inner-heating acupuncture on the expression of Wnt1, Axin and β-catenin in the intervertebral disc of rats with lumbar degenerative disease and to explore the regulatory mechanism of inner-heating acupuncture on the apoptosis of annulus fibrosus cells in rats with lumbar degenerative disease.

Forty SD rats were randomly divided into normal group, model group, inner heating acupuncture group and acupuncture group with 10 rats in each group. Except for normal group, all rats were modeled. Bilateral Da Chang Shu were selected for inner-heating acupuncture and acupuncture treatment. Western-bolt assay was used to detect the expression of Wnt1, Axin and β-catenin in rat intervertebral discs.

Compared with the model group, Wnt1 and β-catenin expression in annulus fibrosus cells of rats in the inner heating acupuncture group and the acupuncture group were significantly decreased(P<0.05);the expression of Axin in annulus fibrosus of rats in the inner heating acupuncture group was significantly increased(P<0.05). There was no significant difference in the expression of Axin in annulus fibrosus of rats between acupuncture group and model group(P>0.05).

Inner heating acupuncture can down regulate the expression of Wnt1 and β-catenin and up regulate the expression of Axin in annulus fibrosus of rats with lumbar degenerative desease. It is suggested that the mechanism may be to regulate the expression of related factors in the β-catenin signaling pathway, so as to achieve the goal of treating lumbar degenerative diseases.
