The total aralosides extracted from Aralia elata (Miq) Seem. were studied in mice ( 50 mg/kg/d for 7 d ) to investigate the pharmacological mechanisms on the molecular level.The results showed that aralosides can obviously stimulate the production of PGE2、PGF2, and cAMP but reduce the cGMP level and nave no effect on histamine release.It is suggested that the changes in the level of cyclic nucleotide might be due to the alternations of PGs, which is now been suspected as the "Second Messenger" . These findings could explain in part the pharmacological activities of aralosides on the molecular level.

Objective To explore the significance of multiple microelectrode guided technique in determining the sensory?motor area of the sub?thalamic nucleus(STN)in deep brain stimulation(DBS)surgeries. Methods A total of 22 electrophysiological recording data of STNs recorded by multiple microelectrode was retrospectively analyzed ,while another 20 electrophysiological recording data of STNs recorded by a single micro?electrode was recruited as the control group. Results A total of 64 microelectrodes were used in 22 STNs guided by multiple electrophysiological recording electrodes. Sensory or motor activated potentials were recorded in 21 sides(95.5%),while regular discharge was recorded in one side. The average length of typical STN activity on the optimal channel of multiple electrophysiological recording electrodes was 5.58±0.53 mm,and the average length of sensory or motor activated potentials was 3.27±1.54 mm. In contrast,the average length of typical STN activity recorded by single microelectrode was 5.02±1.01 mm. However,sensory or motor activated potentials were recorded in 13 sides(65.0%)with the average length of 1.36±0.98 mm. Among the 22 STNs guided by multiple electrophysiological recording electrodes,the final implanted target was consistent with the initially selected anatomic target in 13 sides(coincidence rate,59.1%). In 9 sides,the electrophysiological target was inconsistent with the initially selected anatomic target. Conclusion STN DBS performed with multiple electrophysiological recording electrodes resulted in better outcomes of recording of the average length of typical STN activity or the average length of sensory or motor activated potentials of STN ,final confirmation of STN sensory motor area and determination of the optimal channel of implantation. Application of multiple electrophysiological recording electrodes provides a premise for the precise electrode placement in STN DBS surgeries.

OJECTIVE To investigate the preventive effect of Fengliao extract on ulcerative colitis of mice. METHODS Using the intestinal propulsion rate experiment and senna induced diarrhea model , the intestinal propulsion rate, diarrhea rate and index of diarrhea were observed. Mice were randomly divided into normal group,model group,mesalazine hydrochloride group and Fengliao extract 11.7, 23.4 and 46.8 g · kg-1 group. The mouse colitis model was induced by 4% dextran sulfate sodium. The mice were administraed once daily for 7 d while the disease activity index(DAI)score was calculated and the activity of tumor necrosis factor α(TNF-α),interleukin-1β(IL-1β), myeloperoxidase(MPO) and content of malondialdehyde(MDA) and nitric monoxide (NO) in colon tissue were determined. RESULTS Fengliao extract 46.8 g · kg-1 inhibited the intestinal propulsion rate(P<0.05),reduced the frequency of diarrhea and the diarrhea index(P<0.05). Results of colitis showed that the body mass of mice in the model group was significantly decreased but the DAI score increased compared with normal group(P<0.05). The activity of MPO and the contents of IL-1β,TNF-α,MDA and NO in colon mucosa were increased(P<0.01). Compared with the model group,Fengliao extract 46.8 g·kg-1 decreased the DAI score(P<0.05)while Fengliao extract 46.8 and 23.4 g · kg-1 reduced MPO activity in colonic mucosa and content of IL-1β,TNF-α,MDA and NO in colonic homogenate(P<0.05). CONCLUSION Fengliao extract can significantly improve the DSS induced colitis in mice,which is probably associated with its antispasmodic and anti-diarrheal effect as well as the reduced release of inflammatory mediators and antioxidants.
