Objective The present study was to analyze the role of ACh-lateral septum(SL)pressor system in the Central amygdaloid nucleus(AC)-emotional pressor circuit.Method Interurban microinjection of different drugs,then blood pressure and heart vate were vecorded.Results(1)CRF(corticotropin releasing factor)or SP(substance P)microinjection into the SL can induced pressor responses.The AC pressor responses to glutamate(Glu)could be attenuated by preinjection of CRF antagonist or SP antagonist into bilateral SL.(2)the AC pressor responses to Glu were also reduced by preinjection of atropine into either bilateral HBL,LC or RVL respectively,(3)Since lateral HB(HBL)projects to the posterior hypothalamus(HP)containing ACh-ergic neurons,and excitation of the latter produces pressor response via the RVL and LC-RVL;atropine preinjection into the HP could also decrease the HBL-and AC-pressor response.Conclusion The present results indicate that the AC produce pressor responses involved with the SL via their CRF and SP,mechanism underlying pressor response of SL is involved in pressor response of AC.

Objective To observe the clinical efficacy of auricular point sticking with magnetic bead in treating insomnia in hepatocirrhosis patients. Method Ninety patients with hepatocirrhosis complicated with insomnia were randomized into a treatment group and a control group, 45 in each group. The treatment group was intervened by auricular point sticking with magnetic bead, while the control group was by auricular point sticking with medical adhesive tape. After successive 2-week treatments, the Insomnia Severity Index (ISI) and the Evaluation Criteria of Therapeutic Efficacy for Mental Disorders were observed for evaluating the treatment result. Result The ISI was significantly improved in the treatment group after intervention (P<0.05), and the improvement was significantly different from that in the control group (P<0.05). The total effective rate was 86.7% in the treatment group versus 60.0% in the control group, and the difference was statistically significant (P<0.01). Conclusion Auricular point sticking with magnetic bead is easy-to-operate and can produce a satisfactory efficacy in treating insomnia of hepatocirrhosis patients.

Objective To explore the effects of Tongfu Huayu Daotan Decoction (通化阏导痰汤)on the serum concentration of S-100β protein, neuron-specific enolase(NSE) and Prognosis in patients with severe craniocerebral injury.Methods Sixty patients with severe craniocerebral injury were randomly divided into a a'eatment group and a control group.The treated group was treated with Tongfu Huayu Daotan Decoction plus conventional treatments including dehydration,antibiotics, organ functional support, nerve nutrition, prevention of complication, etc.; the control group was treated with conventional treatments alone. The concentration of serum S-100β protein and neuron-specific enolase(NSE) in plasma at admission and at24, 36, 72huors, and 5, 7 days after treatment were determined respectively; the Glasgow outcome scale (GOS)and neurological deficits scoring at 2weeks and 4weeks after hospitalization were compared to observe the efficacy of the patients. Results The concentration of serum S-100β protein and neuron-specific enolase (NSE) in plasma at previous treatment and at 24, 36 hours after the treatment had no statistical difference in the two groups(P＞0.05 ), The concentration of serum S-100β protein and neuron-specific enolase (NSE) in plasma at 72huors, 5 and 7 days after the treatment in the Tongfu Huayu Daotan Decoction group were lower than those in the control group, the differences being significant (P＜0.01). The Glasgow outcome scale (GOS) and neurological deficits scoring at 2weeks and 4weeks after the treatment in the Tongfu Huayu Daotan Decoction group were significantly nigher than those in the control group, the differences being significant (P＜0.01) .Conclusion Tongfu Huayu Daotan Decoction can alleviate the plasma concentrations of S-100β protein and neuron-specific enolase (NSE) in patients with severe craniocerebral injury and markedly improve the clinical therapeutic effects. Combined Tongfu Huayu Daotan Decoction and western medicine can significantly reduce mortality and improve the Glasgow outcome scale (GOS), neurological deficits scoring and therapeutic effect.

OBJECTIVE：To optimize the primary processing technology of Gentiana rigesce ns. METHODS ：HPLC method was adopted for content determination of loganic acid ，swertiamarin and gentiopicroside in G. rigescens ，and overall desirability value （OD value ） of the contents of above 3 components was taken as index to carry out single factor test on blanching temperature，blanching time and drying temperature. Based on that ，Box-Behnken design-response surface methodology was used to optimize primary processing technology of G. rigescens . Validation test was also performed. The samples prepared by optimized technology were compared with those dried in the shade. RESULTS ：The optimal primary processing technology of G. rigescens included blanching time of 5 min，blanching temperature of 40 ℃ and drying temperature of 60 ℃. Validation test showed that the average OD value of the 3 components was 0.565 2，with a deviation of 0.94％ from the predicted value （0.570 6）. Compared with samples dried in the shade ，OD value of 3 components in samples prepared by optimized technology were increased significantly ， indicating the quality of the samples prepared by the optimized technology was better. CONCLUSIONS ：The optimal technology is stable and feasible ，and can be used for the primary processing of G. rigescens .
