RESUMEN
OBJECTIVE: To observe the effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle (LMM) in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy (PTED). METHODS: A total of 104 patients with lumbar disc herniation treated with PTED were randomly divided into an observation group (52 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). Patients of both groups received rehabilitation training of two weeks 48 h after PTED treatment. The observation group was treated with acupotomy (L3-L5 Jiaji [EX-B 2]) once within 24 h after PTED. In the two groups, the fat infiltration cross sectional area (CSA) of LMM was compared before and 6 months after PTED, the visual analogue scale (VAS) score and Oswestry disability index (ODI) score were observed before and 1, 6 months after PTED. The correlation between fat infiltration CSA of LMM in each segment and VAS score was analyzed. RESULTS: Six months after PTED, the fat infiltration CSA of LMM in L4/L5 and the total L3-S1 segments of the observation group was lower than that before PTED (P<0.05), and the fat infiltration CSA of LMM in L4/L5 of the observation group was lower than the control group (P<0.01). One month after PTED, the ODI and VAS scores of the two groups were lower than those before PTED (P<0.01), and those in the observation group were lower than the control group (P<0.05). Six months after PTED, the ODI and VAS scores of the two groups were lower than those before PTED and 1 month after PTED (P<0.01), and those in the observation group were lower than the control group (P<0.01). There was a positive correlation between the fat infiltration CSA of LMM in the total L3-S1 segments and VAS scores in the two groups before PTED (r = 0.64, P<0.01). Six months after PTED, there was no correlation between the fat infiltration CSA of LMM in each segment and VAS scores in the two groups (P>0.05). CONCLUSION: Acupotomy can improve the fat infiltration degree of LMM, pain symptoms and activities of daily living in patients with lumbar disc herniation after PTED.

OBJECTIVE: To study on relationship of inducible nitric oxide synthase (iNOS) activity and nitric oxide (NO) content in the injured local soft tissue with injured degrees of the soft tissue in the third lumbar vertebrae (L3) transverse process syndrome model rat and to observe the effect of needle-knife therapy. METHODS: One hundred and sixty male SD rats were randomly divided into normal group, model group, aminoguanidine (AG) group, needle-knife group, 40 rats in each group. The L3 transverse process syndrome rat model was established, and after treatment of needle-knife and AG iNOS activities and NO contents and histomorpholocal changes in the soft tissues around L3 transverse process on 1, 3, 7 and 14 days were observed in the groups. RESULTS: Compared with the normal group, iNOS activity and NO content in the model group were significantly increased (P < 0.01); Compared with the model group, iNOS activities and NO contents were significantly decreased in both the needle-knife group and the AG group (both P < 0.01); And both iNOS activities and NO contents were identical with both local inflammation response and injured degrees of the injured tissue in the groups. CONCLUSION: Needle-knife therapy can significantly inhibit generation of NO, alleviate inflammatory response and injured degree of the injured soft tissue, improve microcirculation, prevent formation of pathological scar tissue, and promote repair of the chronic soft tissue injury.
