OBJECTIVE:To establish a method for the contents determination of 4 amino acids in Pyrrosia lingua. METHODS:The samples were analyzed by RP-HPLC. It was performed on a column of Welchrom C18 with the mobile phase A of 0.1 mol/L So-dium acetate buffer(pH6.5)- acetonitrile(93∶7,V/V)and mobile phase B of acetonitrile-water(4∶1,V/V)(gradient elution)at the flow rate of 1.0 ml/min,detection wavelength was 254 nm,column temperature was 30 ℃ and the sample size was 5 μl. RE-SULTS:The linear range was 4.92-49.2 μg/ml for glutamate(r=0.999 1),3.168-31.68 μg/ml for glycine(r=0.999 9),2.6-26 μg/ml for alanine(r=0.999 4)and 2.88-28.8 μg/ml for leucine(r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 2.2%;average recoveries were 98.4%(RSD=2.2%,n=9),99.6%(RSD=2.5%,n=9),98.3%(RSD=2.2%,n=9)and 100.1%(RSD=2.3%,n=9),respectively. CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the contents determination of 4 amino acids in P. lingua.

Objective To observe the effects of Najia method of midday-midnight point selection for acute ischemic stroke (AIS) model rats onthe contents of NSE and S100B protein in serum. Methods SPF SD male rats were chosen to establish the models by middle cerebral artery bolt method. Rats were divided into blank group, sham-operation group, model group, channel-point group, and Najia method group by random number table method. Blank group, sham-operation group, and model group were in the absence of treatment, while the channel-point group received acupuncture treatment according to differentiation syndrome. Najia method group used Najia method of midday-midnight point selection to conduct acupuncture treatment once a day. Improvement of neural function and cerebral infarction volume were observed. The contents of NSE and S100B protein in serum were detected. Results Compared with model group, neurological function score, infarct volume and infarct volume percentage, and the contents of NSE and S100B protein in serum decreased in Najia method group and channel-point group (P<0.05, P<0.01). The effects of Najia group were generally better than the channel-point group. Conclusion Najia method of midday-midnight point selection can decrease the content of NSE and S100B protein in serum of AIS model rats, so as to achieve the effects of neuroprotection and treatment.

Objective To investigate the effects of Ligustilide on the withdrawal syndromes syn-dromes and monoamine neurotransmitters of hypothalamus and nucleus accumbens in morphine-dependent rats. Methods Totally 60 SD rats were divided into control group,model group,clonidine group and Ligust-ilide high(80 mg/kg),medium(40 mg/kg) and low(20 mg/kg) dose group according to the random number table with 10 in each group. Rats were given in gradual increasing doses of morphine to produce physical de-pendence. Morphine withdrawal syndrome was precipitated by naloxone and withdrawal symptoms were evalu-ated by Ryuta Tomoji score. The level of norepinephrine ( NE), dopamine ( DA) and 5-hydroxytryptamine (5-HT) in rats were tested with enzyme-linked immunosorbent assay(ELISA). Results The total score of somatic withdrawal syndromes in the control group,model group,clonidine group and Ligustilide low,medium and high dose group were 0,(31. 83±7. 33),(17. 92±6. 88),(25. 58±5. 99),(19. 88±4. 82) and (16. 75 ±4. 01) . Compared with the model group,the morphine withdrawal syndromes scores of Ligustilide low,me- dium and high dose groups and clonidine group were reduced(all P<0. 05). The level of NE,DA and 5-HT in hypothalamus and nucleus accumbens were increased compared with that of control group. Compared with the model group,the level of NE,DA and 5-HT in hypothalamus and nucleus accumbens of Ligustilide low, medium and high dose groups and clonidine group were significantly reduced (P<0. 05). Conclusion Ligu-stilide can effectively alleviate the symptoms in morphine-withdrawal rats,which may be related to the inhibi-tion of excessive release of monoamine neurotransmitters in hypothalamus and nucleus accumbens.

OBJECTIVE：To establish the fingerprint of crude/vinegar-processed Corydalis yanhusuo decoction pieces and their dispensing granules，and to determine the contents of five alkaloids （protopine，tetrahydropalmatine，corydaline，berberine hydrochloride，palmatine hydrochloride ）. METHODS ：HPLC method was adopted. The determination was performed on Agilent TC-C18 column with mobile phase consisted of 0.1％ phosphoric acid solution-methanol （gradient elution ）at the flow rate of 1.0 mL/min. The detection wavelength was set at 280 nm，and the column temperature was 30 ℃. The sample size was 10 μL. Using palmatine hydrochloride as reference ， Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition） was used to establish the fingerprint of 11 059） batches of C. yanhusuo decoction pieces ，7 batches of crude . yanhusuo dispensing granules ， 12 batches of vinegar- processed C. yanhusuo decoction pieces and 11 batches of vinegar-processed C. yanhusuo dispensing granules. The same HPLC method was adopted to determine the contents of protopine， tetrahydropalmatine， corydaline， berberine hydrochloride and palmatine hydrochloride in 41 batches of crude/ vinegar-processed C. yanhusuo decoction pieces and their dispensing granules. RESULTS ：There were 12 and 20 common peaks for crude C. yanhusuo decoction pieces and its dispensing granules ，and 14 and 16 common peaks for vinegar-processed C. yanhusuo decoction pieces and its dispensing granules. The similarity of each batch of same type were 0.529-0.981，0.342-0.985， 0.711-0.999，0.437-0.998，respectively. The linear range of protopine ，tetrahydropalmatine，corydaline，berberine hydrochloride and palmatine hydrochloride were 1.9-38.0，2.0-40.0，2.2-44.0，2.6-52.0，2.3-46.0 μg/mL（R2＞0.999 0）. The recoveries were 100.12％-100.98％（RSD＝1.05％-1.90％，n＝9）. RSDs of precision ，reproducibility，stability（24 h）and durability tests were all lower than 2.0％. The average contents of five alkaloids in different batches of crude/vinegar-processed C. yanhusuo decoction pieces and its dispensing granules were 0.24-0.46，0.37-0.82，0.24-0.58，0.07-0.75，0.24-0.76 mg/g. RSDs were 12.27％-147.48％. CONCLUSIONS：The fingerprint of crude/vinegar-processed C. yanhusuo decoction pieces and its dispensing granules is established successfully. The similarities of fingerprint are different before and after processing with vinegar ，and the contents of five alkaloids in C. yanhusuo decoction pieces and its dispensing granules are greatly different.
