Pharmacological evaluation on the improvement of sleeping effect usingSi-Ni-San(SNS) in order to conduct further study on scientific connotation of soothing liver-qistagnation. Rats, mice and fruit flies were used as animal model. Pharmacological assessment was conducted and done on the improvement of sleep effect by SNS with the cortical EEG scanning and analysis, biochemistry, molecular pharmacological methodology and technology. SNS can prolong the sleeping time of mice which were induced by pentobarbital sodium. Its effect showed the dose-dependent and time-dependent manner. It can prolong the slow-wave sleep time in normal and sleep deprivation rats. It influenced several neurotransmitters and endogenous sleep factors in brain of normal and sleep deprivation rats. SNS can improve sleeping. The effect was closely related the effect of soothing liver-qi stagnation. The function was realized through multiple pathways and targets.

ObjectiveTo discuss the impact of conflict psychological stress on rats'sleep time and sleep phrase.Methods20 Wistar male rats were randomly divided into vehicle group and model group,10 in each group.The improved experiment of Vogel drinking water conflict was used to establish the model of conflict psychological stress in rats and monitoring the changes of rats'weight and concentration of corticosterone (CORT) in serum after a week.After one week,the 12 h EEG and EMG of rats were traced by the polygraph in order to clarify the effect of conflict psychological stress on rats′ sleep time and sleep phrase.ResultsAfter one week,compared with vehicle group the weight of model group decreased significantly ( t =2.87,P ＜ 0.05 ),the concentration of CORT in serum raised significantly( t=5.19,P ＜ 0.05 ).A week later,compared the vehicle group,total sleep time( TST),light sleep,slow wave sleep(SWS) and rapid eye movement sleep (REM) time in model group rats ( (337.8 ±84.2)min,( 169 ±49.2) min,( 136.9 ±40.8)min,(33.1 ± 10.1 ) min for vehicle group; ( 155.4 ±16.7 ) min,( 111.6 ± 16.4 ) min,( 30.6 ± 4.9 ) min,( 12.6 ± 3.3 ) min for model group) were significantly reduced ( t =6.75,2.43,5.51,5.78,P ＜ 0.05 ),and the proportion of lightsleep increased ( (49.6 ± 3.4 ) ％,( 71.7 ±5.4)％ ) ( t =6.90,P＜0.05),the proportion of SWS decreased( (40.3 ± 10.9)％,( 19.8 ±3.2)％ ) ( t=6.74,P ＜ 0.05 ) ;but no significant change in the proportion of REM ( t =1.57,P＞ 0.05 ).Rats,sleep-wake rhythm figure indicated that the rats'sleep duration reduced and the number of awakening increased ; sleep tended to be fragmentation.ConclusionsConflict psychological stress lead to hypothalamus-pituitary-adrenal axis hyperactivity,weight loss,and the rhythm of sleep and sleep phase change in rats.

Objective To investigate the influence of illumination changes on the drosophila circadian rhythm and 24 h sleep time.Methods We collect the unmated fruit flies (a total of 128,single-sex) under CO2 anesthesia within 8 hours of eclosion.And put them into the group of normal light group,day and night reversed group,24 h light group and 24 h dark group with the simple random sampling method,male and female with 4 single-sex groups(n=32).Change the illumination conditions of the living environment of the fruit flies and use Drosophila Activity Monitoring System (DAMS) and Data Acquisition System (DAS),to observe and compare the changes of drosophila circadian rhythm and 24 h sleep time between the different illumination conditions.Results Compared with the normal light group,drosophila circadian rhythm of the day and night reversed group was significantly reversed,the number of fruit flies' activities of 24 h light group was increased,and circadian rhythm was decline,drosophila circadian rhythm of the 24 h dark group is still there,but frequent activity appears during the day,and the 19 : 00 activity peak disappears.Conclusion The drosophila circadian rhythm and 24 h sleep time changes with illumination conditions change.

AIM To investigate the effects of ethyl acetate extract from Huangqi Injection (HQIEACE) on leucopenia mice.METHODS An experimental mouse model of leucopenia was induced by cyclophosphamide.NMR based metabolomic profiling technique coupled with multivariate statistical method was used for performing metabolomic analysis.RESULTS HQIEACE could elevate the levels of white blood cell,monocytes,neutrophils and lymphocyte in modeled mice.The levels of ten potential endogenous metabolites (lipid,leucine,3-D-hydroxybutyrate,lactate,alanine,pyruvate,creatine,scyllo-inositol,betaine and glucose) were reversed.CONCLUSION The metabolic pathways related to the pharmacological effects of HQIEACE on leucopenia are probably involved in body energy metabolism,amino acid metabolism,oxidative stress and choline metabolism.

Objective To evaluate the effect of olmesartan medoxomil tablets (olmesartan) in comparison with Olmetec on 24 h ambulatory blood pressure (ABPM) and blood pressure variability (BPV)in patients with mild to moderate hypertension.Methods A randomized,double-blind,double-mimic controlled trial was performed.Forty-eight patients with mild to moderate essential hypertension were randomly into treatment group (olmesartan) and control group (Olmetec) for eight weeks.The ABPM was taken before and at the end of the trial.Results After eight weeks,treatment with olmesartan induced a significant reduction in ABPM in patients [(9 ± 3)/(11 ± 3) mmHg (1 mmHg =0.133 kPa)],which is similar with the reduction by Olmetec [(9 ± 4) / (9 ± 5) mmHg],P ＞ 0.05.This situation holds for BPV with the standard deviations of 24 h,systolic blood pressure/diastolic blood pressure of pre-treatment and pro-treatment were (10 ± 2)/(11 ± 3) mmHg vs (10 ± 3)/(12 ± 2) mmHg in olmesartan group,and (10 ± 3)/(11 ±3) mmHg vs (12 ±3)/(12 ±4) mmHg in Olmetec group.(3) There is no difference in the rate of adverse event between olmesartan (10.42％) and Olmetec (8.33％) treatment(P ＞ 0.05).Conclusion Similar to Olmetec,treatment with olmesartan once daily can significantly reduce ABPM in patients with mild to moderate essential hypertension.
