CONCLUSION: The HPLC-FP of Fructus aurantii has been established.The method can be used to identify and evaluate the quality of Fructus aurantii.

Objective To study the anti-depressant effect of Xiaoyaofang on mice with behavioral despair. Method The mice were given the forced swimming test and tail suspension test to observe the anti-depressant effect of Xiaoyaofang. Result The high dosage of Xi-aoyaofang significantly shortened fast time in the tail suspension test of mice(P < 0.05). And Xiaoyaofang showed the trend of shortening the needed time in the forced swimming test. Conclusion Xiaoyaofang have an anti-depressant effect on mice with behavioral despair.

Objective To explore effect of Simotang on gastrointestinal motility and expression of vasoactive intestinal peptide(VIP) in the hypothalamus, spinal cord and duodenum of chronical stressed mice. Methods Mice were randomly divided into normal, stress and Simotang group( n= 10 in each group), and given a variety of unpredictable chronic mild stress. After 21 days gastric emptying and intestinal propulsion function were measured,the expression of VIP was detected by immunohistochemistry and RT-PCR. Results Compared with mice in normal group( (49.81 ± 8.56)%; (51.02 ± 5.11 )% ), chronic stress increased gastric residual rate( (61.53 ±8.71 ) %; P ＜ 0.05 ) and reduced small intestine propulsion rate ( ( 31.79 ± 2.38 ) %; P ＜ 0. 05 ). There were differences in expressions of VIP positive cells and mRNA in duodenum( (8.8 ± 1.1 )/mm2 and(0. 58 ±0.03) ),hypothalamus ( ( 12.9 ± 1.5 )/mm2 and (0.81 ± 0. 07 ) ) and spinal cord ( ( 12.1 ± 1. 2)/mm2 and (0.76 ± 0.02) )in chronic stress group compared with normal group( (6.5 ± 0. 9)/mm2 and (0.43 ± 0. 04);( 10.8 ± 1.3 )/mm2and (0.57 ± 0.03 ); (9.3 ± 1.5 )/mm2 and (0.53 ± 0. 02 ) respectively). There was not difference in gastric residual rate (52.93 ± 9.15 )%, small intestine rate(48.98 ± 4.38 )% and expressions of VIP positive cells and mRNA in duodenum ( (6.7 ± 0.9)/mm2 and (0.48 ± 0. 05 ) ), hypothalamus ( ( 10. 6 ± 1.4 )/mm2 and ( 0. 61 ± 0. 05 ) )and spinal cord ( (9. 1 ± 1.3)/mm2 and(0.55 ± 0.05 ) ) in Simotang group compared with those in normal group (P ＞ 0.05 ), but there were decreased compared with those in chronic stress group (P ＜ 0.05 ). Conclusion Simotang can regulate expressions of VIP in duodenum, hypothalamusand spinal cord in chronically stressed mice.

Objective To explore the effect of Buyang Huanwu decoction(BYHWD)on protein kinase B1 (AKT1)and c-Jun amino terminal kinase 1/2(JNK1/2)in rats after focal cerebral ischemia. Methods According to the random number table method,48 Sprague-Dawley(SD)rats were randomly allocated to four groups:normal control group,sham-operated group,model group,traditional BYHWD group(each n=12). The rat model of right focal cerebral ischemia was established by the method of middle cerebral artery occlusion(MCAO). The rats in BYHWD group were ingested with the decoction of BYHWD 14.2 g/kg after 2 hours of the operation(the main ingredients of BYHWD including astragalus mongholicus 120 g,Chinese angelica 6 g,radix paeoniae rubra 4.5 g, rhizoma ligustici wallichii 3 g,safflower 3 g,peach kernel 3 g,earthworm 3 g),once a day for 7 days. Other groups of animals were given the same amount of normal saline orally. After operation,on the 7th day,the animals were killed,and their brains were taken out. The reverse transcription-polymerase chain reaction(RT-PCR)assay was used to detect AKT1 mRNA expression,and immunohistochemical method was applied to measure JNK1/2 protein expression. Results Compared with normal control and sham-operated groups,the level of AKT1 mRNA expression〔absorbance(A)〕was decreased obviously(0.48±0.08 vs. 0.63±0.11,0.61±0.09,both P<0.05),and the number of JNK1/2 positive cells(cell/mm2)was increased significantly(34.13±4.57 vs. 16.15±1.09,16.23±2.05,both P<0.05)in model group;compared with model group,the AKT1 mRNA expression in brain tissue(0.93±0.11)and the number of JNK1/2 positive cells(45.04±5.68)was increased significantly in BYHWD group,the differences being statistically significant(P<0.05 or P<0.01). Conclusion BYHWD can up-regulate expressions of AKT1 mRNA and JNK1/2 positive cells in ischemic brain tissue that is one of the mechanisms in the protection of brain.
