Sixty lumbar intervertebral disc herniation (LDH) cases were treated with electroacupuncture on such major points as Jiaji ( Ex-B 2) in L4, L5, and S1 and Huantiao (GB 30) as well as adjunctive corresponding points in the affected area plus short-lever micro-adjustment manipulation. Another 60 cases in the control group were treated with tra-ction. After three treatment courses, the former got the effective rate of 93.3%, while the latter only got 77.8%. The two groups have a statistical difference in therapeutic effect (P＜0.05).

Hypoxia inducible factor-1αis a kind of hypoxia response factor. Acute cerebral ischemia and anoxia can induce up-regula-tion of hypoxia inducible factor-1α, and the downstream genes, which plays a role in both the energy metabolism and collateral circulation after cerebral ischemia. Neural stem and progenitor cells regeneration also benefit the functional outcome after ischemic stroke. Hypoxia in-ducible factor-1αmay induce proliferation and differentiation of neural stem and progenitor cells through Notch, Wnt/β-catenin pathways, etc., in the ischemic stroke model.
