This study was aimed to quickly and accurately identify different origins and categories of commodity edible bird’s nest (EBN) using DNA barcoding technique, in order to reveal its genetic differences. The total genomic DNA was isolated from the EBN samples. And Cytb gene sequences were amplified and sequenced by PCR. Then, 32 sequences were aligned and analyzed with DNAStar and MEGA 6.0 software. NJ phylogenetic tree was constructed. The nearest distance was calculated. The results showed that the original species of 32 samples of EBN were identified.Aerodramus fuciphagus was the genetic origin of 23 white nest samples. AndAerodramus fuciphagus germaniwas the genetic origin of the other 8 samples. The origin of black nest sample wasAerodramus maximusorAerodramus maximus lowi. It was concluded that the genetic origin of different EBN categories was variant. The identification of EBN’s origin species with Cytb sequence was quick and accurate.

Guangdong province assumes the task of pilot exploration and demonstration for building the preventive health service system of Chinese medicine. In the pilot process of preventive treatment of disease, a health pro-ject of Chinese medicine, sectoral agreements and policy studies are focusing issues. This paper explores the pre-ventive health service system building of Chinese medicine in G uangdong province , from following aspects such as access policy of service agencies, access policy of professional service staff, evaluation mechanism and verify sys-tem, the revision of existing medical subjects of medical institutions, health insurance policies and compensation policies, price policies, proactive technology policies and fiscal policies, incentive policies for the introduction of private capital .

Objective To evaluate the pharmacokinetic parameters and bioavailability of puerarin in Yufeng Ningxin tablets in mice by determining dose-time curve and by comparing with the pharmacokinetics of puerarin injection.Methods NIH mice were randomized into different groups. 6 %HClO4 was used to precipitate plasma protein and the plasma concentration of puerarin in mice was determined by HPLC.The PK solutions 2.0 program,a non-compartmental model software,was applied to calculate the pharmacokinetic parameters and bioavailability.Results The main pharmacokinetic parameters of puerarin injection by i.v.in mice were:t1/2=98.359 min,CL=35.548 mL?min-1,AUC(0-∞)=281.3 ?g?min?mL-1;the main pharmacokinetic parameters of puerarin in Yufeng Ningxin tablets by o.p.were:t1/2 =35.562 min,CL=898.685 mL?min-1,Cmax=9.3 ?g?mL-1,Tmax=30 min,AUC(0-∞)=222.5 ?g?min?mL-1 ,F(bioavailability value)=3.95 %comparing to puerarin injection.Conclusion As compared with puerarin injection,the absorptive content of puerarin in Yufeng Ningxin tablets is very poor and the bioavailability is also low,indicating that enhancement of bioavailability of Yufeng Ningxin tablets will be beneficial to the clinical application.

Objective To establish a method for the determination of berberine and salvianolic acid B in Fuyankang En- ema.Methods The chromatograhie separation was performed on a Kromasil C_(18) column (250 mm?4.6 mm,5?m) with a gradient elution of acetonitrile-0.04 mol/L potassium dihydrogen phosphate solution containing 0.1% phosphoric acid.The flow rate was 1.0 mL/min and column temperature was set at 30℃.The detection wavelength was 230 nm.Results There was a good linearity in the range of 0.0924～2.3100?g (r=0.999 9) for berbeine,and 0.1000～2.5000?g (r=0.999 9) for salvianolic acid B.The average recoveries of berberine at high,middle and low concentra- tions were 100.40 %,99.51% and 99.15 % respectively with RSD being 0.59 %,0.67 %and 1.02 % (n=3) re- spectively.The average recoveries for salvianolic acid B were 101.52 %,99.32 % and 98.68 % respectively with RSD being 0.60 %,0.92 % and 1.00 % (n=3),respectively.Conclusions This method is convenient,specific and re- producible for the determination of berbeine and salvianolic acid B in Fuyankang Enema by HPLC.

Objective To optimize the soaking treatment method for increasing the germination of Amomum villosum Lour.(AVL) seeds.Methods Nine groups were set up: the control group(without soaking treatment),treatment group 1(soaking AVL seeds with naphthylacetic acid 15 mg/mL for 8 hours),treatment group 2(soaking with gibberellin 100 mg/L for 30 hours) and treatment groups 3~8(soaking with clean water for 8,20,30,40,45 and 50 hours respectively).The sowing amount was 100 grains in each group for each time,and the seeds were planted in the outdoor pot at a planting space of 4cm?4cm.Results Naphthylacetic acid had an obvious inhibition on the germination of AVL seeds and delayed the shooting.Gibberellin promoted the germination and shooting of the seeds.Soaking with clean water for 8 hours had no obvious effect on the seed germination,but soaking for 20~50 hours increased the seed germination to various degrees,in particular soaking for 30~50 hours.Conclusion Soaking with gibberellin or clean water can increase the germination of AVL seeds.This method is simple and practical and economic,and is worth of extensively applying in the sowing and breeding of AVL seeds.

Objective To study the effect of different treatment methods on seed germination of wild Morinda officinalis How(MOH),which will provide evidence for breeding new cultivars of MOH.Methods We observed the morphological feature,thousand-seed weight and hygroscopicity of wild MOH,and studied the effect of different treatment methods on the germination rate,germination vigor,and germination index of the seeds.Results The thousand-seed weight was 38.03 g and the seed coat had good hygroscopicity.Stripping seed coat,acid etching with sulfuric acid,and the combined treatment of stripping seed coat with exogenous hormones of gibberellin(GA) and 6-benzyladenine(6-BA) had an effect on increasing germination rate,and the germination rate arrived 88.89% after the combined treatment of stripping seed coat with 4 mg/L 6-BA.Conclusion The germination inhibitors containing in the seed coat mainly contribute to the difficulty of the germination of MOH,and the germination inhibitors containing in the seed also have some influences on the germination.
