Objective: To observe the clinical efficacy of warm needling moxibustion plus lumbar traction for lumbar disc herniation (LDH) and its effect on Oswestry disability index (ODI) score, present pain intensity (PPI) score, and the degree of straight leg raising.Methods: A total of 146 patients with LDH were randomized into a combination group and a control group by the random number table method, with 73 cases in each group. The control group was treated with lumbar traction, and the combination group was treated with lumbar traction plus warm needling moxibustion. The curative efficacy of the two groups was compared. Also, the lumbar function, pain, straight leg raising degree, and inflammatory factor levels before and after treatment were compared. Results: The total effective rate of the combination group was 93.2％, which was higher than 78.1％ of the control group (P<0.05). After treatment, the lumbar ODI score, the PPI scores of lumbar pain and lower-limb pain, tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels, and straight leg raising test score in both groups were significantly decreased (P<0.05). The Japanese Orthopaedic Association (JOA) score significantly increased (P<0.05). The improvements of the above items in the combination group were all superior to those in the control group (P<0.05). Conclusion: Warm needling moxibustion plus lumbar traction in the treatment of LDH can improve lumbar function, relieve pain, and reduce inflammatory response of the body.

BACKGROUND:Bone marrow mesenchymal stem cells (BMSCs) can be induced to differentiate into neuron-like cells directional y. Accordingly, BMSCs can be used as seed cells theoretical y in constructing tissue-engineered peripheral nerves.
OBJECTIVE:Using combination of two cytokines to induce BMSCs differentiating into neuron-like cells directional y, and further to discusse its application in peripheral nerve injury.
METHODS:BMSCs were isolated and purificated from the bone marrow of Wistar rats by using the differential adherence method. Basic fibroblast growth factor and epidermal growth factor were used to induce the BMSCs differentiating into neuron-like cells. The morphological change was observed and the neuronal specific markers were detected by immunohistochemistry technique. The morphological and immunohistological changes were also studied after the induce agent were removed.
RESULTS AND CONCLUSION:With presence of morphological and immunohistochemical features of nerve cells induced by neurotrophic factors, BMSCs exhibited two or more processes that were interconnected as a meshwork;cellnucleus and nucleus could be observed with strong light refraction of cytoplasm. After immunohistochemical staining, neuroln specific enolase, neurofilament protein and synaptophysin protein positive cells were detected. A great amount of cells reversed to their original fibroblast-like morphology, and the expression of the three above-mentioned proteins decreased as the induce agent withdrawn. Our study showed that BMSCs can be induced to differentiate into neuron-like cells, but the transdifferentiation is a short-time reversible phenomenon.
