[ Objective ] To investigate the effect of electroacupuncture ( EA) on synaptic transmission in hippocampal dentate gyrus of rats with cerebral ischemic damage. [Methods] Sixty Wistar rats were enrolled into this study. Among them, 30 were given high-frequency stimulation (HFS) and the other 30 were not. Then the HFS rats were randomized into sham-operation group (group A), model group (group B) and acupuncture group (group C); so did the non-HFS rats. Bilateral carotid arteries were exposed but not blocked in Group A, while were blocked by traction with silk thread for modeling in group B. Group C were treated with EA before and after modeling. Effects of EA on synaptic transmission in hippocampal dentate gyrus of non-HFS rats were evaluated with in-vivo long-term potential ( LTP) recorded by electrophysiological technique. Effects of EA on LTP in hippocampal dentate gyrus of HFS rats were observed after LTP was induced by HFS. [Results] In non-HFS rats, no significant changes of magnitude of population spike (PS) occurred within 120 min in group A; magnitude of PS in group B decreased at 10th min after modeling ( P

As a part of the project for the Chinese Pharmacopoeia (2015 edition), the quality standard of Sophora flavescens root extract was investigated and established. According to the methods described in the Appendix of Chinese Pharmacopoeia (2010 edition), the water and ash inspections were carried out. The marker components trifolirhizin, sophoraflavanone G, oxymatrine and oxysophocarpine in the samples were identified by qualitative TLC. The determination of oxymatrine, matrine, oxysophocarpine and sophocarpine was conducted by HPLC and the total flavonoids were measured by ultraviolet spectrophotometry, using sophoraflavanone G as reference substance. The results indicated the spots on the plate were clear with good resolution and the contents of oxymatrine, matrine, oxysophocarpine and sophocarpine in the 13 batches of the samples were 3.87% - 11.1%, 0.970% - 4.33%, 1.30% - 2.59% and 0.260% - 1.14%, respectively. The total flavoids in the 13 batches of the samples were 3.88% - 7.93%. In the study, the validated methods were reproducible and the established quality standard was feasible, which could be used for the quality control of S. flavescens root extract and related preparations.

OBJECTIVETo explore the therapeutic effect and safety of fire needling on rat with rheumatoid arthritis.
METHODSForty female Wistar rats were randomly divided into a normal group, a model group, a methotrexate (MTX) group and a fire needling group, 10 rats in each group. The 0.1 mL of normal saline was subcutaneously injected in rat's right back paw in the normal group, while the other groups received subcutaneous injection of 0.1 mL of complete Freund's adjuvant to establish the model. The pricking method was applied in the fire needling group at "Jiaji" (EX-B 2), "Zusanli" (ST 36) and Ashi points with a depth of 5 mm, once every three days, and totally eight times were required. In the MTX group, with intragastric administration of 2.0 mg/kg per rat, the treatment was given once every seven days, and totally four times were required. The weight, swelling rate of foot, joint pain score and polyarthritis index of rats in each group as well as the pathological change of liver tissue under light microscope were observed.
RESULTSThe weight, swelling rate of foot, joint pain score and polyarthritis index in the model group were significantly higher than those in the normal group (P < 0.05, P < 0.01), after the treatment, the above-mentioned indexes in the two treatment groups were obviouly dereased as componed with those in the model group (all P < 0.01), and there were statistical differences between the fire needling group and MTX group (P < 0.05, P < 0.01). Compared with the normal group, inflammatory cells were appeared with a cluster distribution in the liver cells of rats in the model group. The inflammatory cells were reduced in the MTX group and fire needling group, and liver cells had degenerative edema and cell nucleus were largen and deformed in the MTX group.
CONCLUSIONThe fire needling has significant efficacy for rats with adjuvant arthritis (AA) without any damage to the liver, which coud have a better control of disease progression of rheumatoid arthritis .

Cerebral ischemia is one of the most common diseases treated by acupuncture therapeutics. Recent studies indicated that acupuncture treatment by needling the conception and governor vessels had positive effects in promoting neural regeneration in patients after cerebral ischemia injury. Acupuncture intervention could continuously promote the proliferation and differentiation of the neural stem cells in the brain, obviously up-regulate expression of growth factors, accelerate angiogenesis and inhibit apoptosis. Hence, it is necessary to present an exhaustive review on the mechanisms. The present review gives a detailed description of pathological changes of cerebral ischemia and acupuncture intervention applied to the conception and governor vessels, and proposes research prospects in the future.
