    Abstract:
    OBJECTIVE: To observe the effect of small needle-knife lysis on plasma calcitonin gene-related peptide (CGRP), endothelin (ET), 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha), thromboxane A2 (TXA2) contents in rats with experimental third lumbar vertebra transverse process syndrome (TLVTPS) so as to explore its underlying mechanism in clinical treatment. METHODS: Forty SD rats were randomly divided into normal control, model, lysis and EA groups. TLVTPS model was established by embedding a piece of gelatin sponge (0.5 cm x 0.5 cm) to the transverse process of the 3rd lumbar vertebra under anesthesia. EA (2/100 Hz, 1-2 mA) was applied to left "Shenshu" (BL23) -"Yaoyangguan" (GV3) for 20 min, once every other day, 6 times altogether. For animals of lysis group, the lysis was performed by using a small needle-knife in the induration spot or cord-like region near the incision, once a week and twice altogether. Four weeks later after modeling, plasma CGRP, ET, 6-keto-PGF1alpha and TXA2 contents were detected by using radioimmunoassay and enzyme linked immunosorbent assay (ELISA). RESULTS: Compared with normal control group, plasma CGRP, ET, TXA2 and 6-keto-PGF1alpha increased significantly in model group (P<0.01); in comparison with model group, plasma CGRP, TXA2 and 6-keto-PGF1alpha in both EA and lysis groups decreased considerably (P<0.05, 0.01). No significant differences were found between EA and lysis groups in plasma CGRP, ET and 6-keto-PGF1alpha levels (P>0.05). CONCLUSION: Both EA and lysis of acupotomology have an adjusting effect on vasoactive substances (CGRP, TXA2 and 6-keto-PGF1alpha) levels in TLVTPS rats, which may contribute to their effects in improving local blood circulation and relieving soft tissue injury in the treatment of third lumbar vertebra transverse process syndrome.
