ABSTRACT
<p><b>OBJECTIVE</b>To explore the mechanism of acupotomy lysis in treatment of the third lumbar vertebrae transverse process syndrome.</p><p><b>METHODS</b>One hundred and eighty patients were randomly assigned into an acupotomy group and an electroacupuncture (EA) group, 90 cases in each group. The acupotomy group was treated with acupotomy on the tip of the 3rd lumbar vertebrae transverse process (tender point) combination with massage manipulation of hyperflexion and hyperextension on the waist, once a week for 3 weeks. The EA group was treated with EA at bilateral Shenshu (BL 23), Yaoyangguan (GV 3), Ashi point (local tender point) and ipsilateral Weizhong (BL 40), 3 times a week for 3 weeks. The 500 g pressure displacement and the energy absorption ratio were measured by JZL-II soft tissue tension meter and the clinical effect was evaluated by JOA low back pain scale before treatment, after treatment and 6 months after treatment.</p><p><b>RESULTS</b>After treatment and at follow-up visit, the 500 g pressure displacement in the acupotomy group increased significantly (both P < 0.01), but it was decreased significantly in the EA group (P < 0.05, P < 0.01). The energy absorption ratio in the acupotomy group after treatment and at follow-up visit increased significantly (both P < 0.01), and in the EA group, there was no significant difference after treatment as compared with that before treatment (P > 0.05), but it was increased significantly at follow-up visit (P < 0.01). The total therapeutic level distribution in the acupotomy group was better than that in the EA group after treatment and 6 months after treatment (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Acupotomy therapy can significantly increase the 500 g pressure displacement and the energy absorption ratio of the local soft tissue around the third lumbar vertebrae transverse process, decrease the local soft tissue tension so as to alleviate pain. The clinical effect of the acupotomy is superior to that of electroacupuncture.</p>

<p><b>OBJECTIVE</b>To study the analgesia mechanism of needle-knife lysis in spinal cord and other parts of central nervous system by comparing the changes of Leu-Enkephalin (L-ENK) content in different parts of centrium of rats undergone needle-knife lysis and electro-acupuncture respectively.</p><p><b>METHODS</b>Sixty healthy SD rats were randomly devided into normal control group, model group, needle-knife lysis (NKL) group and electro-acupuncture (EA) group. 4% papain solution mixed with 0.3 mol/L cysteine solutin in the ratio of 1:1, paused for 0.5 h,injected the mixture, 20 microl each time,into the left knee joint cavities of rats in model, NKL, EA groups at the 1st, 4th, 7th day. After 4 weeks in NKL group and EA group were treated with needle-knife lysis and electro-acupuncture, respectively. Three weeks after treatment, samples of spinal cord of the swollen part of rat waists and rat brains were taken from and the content of L-ENK of medulla oblongata, midbrain, pituitary gland, and hippocampus were measured.</p><p><b>RESULTS</b>L-ENK content of model group increased higher than that of normal control group in spinal cord, hippocampus and midbrain (P < 0.01); there were no significant difference between normal control group and modle group on L-ENK in medulla oblongata and thalamus (P > 0.05). After intervening of NKL or EA, L-ENK content of NKL group increased higher in hippocampus than that of model group and EC group (P < 0.05); but L-ENK content of NKL group in midbrain was lower than that of model group (P < 0.05).</p><p><b>CONCLUSION</b>Needle-knife lysis has characteristic of regulation for the L-ENK content in different parts of central nervous system of rats with knee osteoarthritis, and analgesic effect of needle-knife was possibly related with regulation of center L-ENK.</p>
