Based on the findings of the past five decades, the seasonal regularity of respiratory disease was summed leading to respiratory tract diseases were summed up.

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.

Objective: To study the technological parameters of the enrichment purification process of Baohe Pills with macroporous resin. Methods: With the enriched degree of hesperidin of Pericarpium Citri Reticulatae of Baohe Pills as a marker, the optimum technological parameters of the enrichment process were studied. Results: The optimum process is that 5mL of the extract of BaoHe Pills (500mg/mL) was adsorbed for 30min with a column of macroporous resin (R15mm?H100mm) and the resin was washed with 100mL of distilled water, then the hesperidin was eluted from the macroporous resin with 100mL of 50% ethanol. Conclusion: The elutive rate of hesperidin was above 95% by means of the macroporous resin. So this process enriching the active components of Baohe Pills is feasible.

Objective To study the influences of polysacch arides(PS)from Radix Codonopsis on immune function and hematopoiesis in mice.Methods Several experiments have been condu cted for detecting delayed type hypersensitivity(DTH),hemolysin antibody concentration,endogenous spleen colony,3 H-TdRpermeate nuleated cells in bon e marrow.Results By oral administration,PS from Radix Codonopsis can promote the humoral immunity and PS at a small dosage en-hance the cellular immunity.PS from Radix Codonopsis can also elevate the hemoglobin cont ent of the hemolysis -induced blood -deficiency mice and increase the formation of endogenous spleen c olony,but has less effect on DNA synt hesis in the bone marrowof blood -deficiency mic e caused by 60 Co -?ray.Conclusion PS from Radix Codonopsis can enhance the im-mune function and improve the compen satory hematopoiesis of spleen and t heir mechanisms need to be further studied.

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 investigate the effect of open nursing management on hospital rehabilitation of patients with schizophrenia.MethodsThe outcome of group A,which included 113 patients in open nursing management,and group B,which included 141 patients in close nursing management at the same time,were evaluated with the Brief Psychiatric Rating Scale(BPRS)and the Nurses' Observation Scale for Impatient Evaluation(NOSIE),etc.ResultsThe difference between the two groups in such as the time of symptoms improved,drugs administration,effective rates were not significant(P>0.05).The compliance of medicine,social capability and personal sanitation of group A were improved compared with those in group B(P<0.05),while the time stay in hospital obviously shortened(P<0.01).ConclusionThe open nursing management is helpful to improve the rehabilitation and shorten the time stay in hospital of patients with schizophrenia.

Object To study the volatile constituents in the TCM preparation "Pao Chai Pill" made in Yangcheng (Guangzhou) (YPCP) in comparison with that made in Hongkong (HPCP) to gain some insight for the renewal of YPCP to a new dosage form Methods The volatile constituents were extracted with the aid of ultrasonic wave in organic solvent, and identified by GC-MS and elucidated on the standard MS data Their relative contents in percentage were calculated by area normalization Results 24 and 20 volatile constituents were identified in YPCP and HPCP respectively Conclusion YPCP showed more rich in sesquiterpene lactones but less sesquiterpenes and sesquiterpene alcohols than HPCP

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.
