OBJECTIVE:To facilitate the construction of Chinese pharmaceutical profession associations. METHODS: We analyzed the current situation and problems existing in Chinese pharmaceutical profession association as well as the developmental experience of foreign pharmaceutical associations then put forward suggestions for the development of pharmaceutical profession associations in China. RESULTS & CONCLUSIONS: The sound development of pharmaceutical profession associations calls for the cooperated efforts of government, profession association and pharmaceutical enterprises, meanwhile its function as bridge and tie between pharmaceutical enterprises and government should be brought into full play.

Objective:To study the value of clinical application of 16-slice spiral CT in the diagnosis of acute chest pain.Methods:53 cases who presented with acute chest pain were included in the study.All of the patients underwent CTA examination to evaluate the coronary arteries,pulmonary arteries,thoracic and abdomen aorta.Coronary arteries angiography and interventional therapy was performed in 6 of the 53 cases.Multi-planar reconstruction(MPR),maximum intensity projection(MIP),curved-planar reconstruction(CPR)and volume rendering(VR)were used to display coronary arteries,pulmonary arteries,thoracic and abdomen aorta.The image quality was then evaluated according to whether the examinations can fulfill the clinical demand for the differential diagnosis of acute chest pain.Results:In the 53 cases,there were 33 cases with coronary arteries disease,9 cases with aortic dissection or dissecting aneurysm,2 cases with pulmonary arteries embolism,2 cases with spontaneous rupture of esophagus,2 cases with pneumothorax.Conclusion:CTA examination with 16-slice spiral CT can display the coronary arteries,pulmonary arteries,thoracic aorta in 11～13s with good image quality.It is of great value of clinical application in the etiological diagnosis for the patients with acute chest pain.

Objective:To explore the possible molecular mechanism of inhibiting the proliferation of lung cancer cells by studing curcumin regulating neucleoprotein ?-catenin,the key factor of Wnt signaling pathway.Methods:Non-toxic different doses of curcumin affected human lung adenocarcinoma cell A549 for 48 hours.Inhibitory effect of curcumin on proliferation of A549 cells was evaluated by MTT assay.The correclation of doses and inhibition ratio was analyzed statistically.The neucleoprotein levels of ?-catenin was analyzed by Western blot.The expression level of c-myc was analyzed by reverse transcription-polymerase chain reaction(RT-PCR).The exchange of cell cycle was examined by flow cytometry(FCM).Results:Curcumin inhibited the proliferation of A549 in a concentration-dependent manne(rP

By using the method of eross-sectional anatomy, we examined human eerebral asymmetries in 31 Chinese adult brain.The left cortical language areas is larger than the right. The distribution of the hemispheric asymmetries is compatible with that reported by CT scan.The asymmetry of the posterior language areas mainly reflect the asymmetry of the occipital length and the asymmetries of the wide occipital lobe and the wide occipital horn might be in relation to the handedness. Though both the anterior and the posterior language area are mostly larger on the left hemisphere,there is no relationship between them

2,5-DKG reductase I was purified from cell-free extracts of a recombinant,ER97 by a procedure involving ammonium sulfate precipitation and successive column chromatography on DEAE-Sepharose CL-6B and Phenyl Sepharose CL-4B with 5 fold purification,27 % recovery and 3418 U/mg specific activity.The molecular weight of the enzyme estimated by SDS-PAGE was 34kD.The isoelectric point was estimated to be 6.0 by PAG-IEF.The optimum pH was 7.0 and the optimum temperature was about 40℃.The enzyme can catalyze the stereospecific NADPH-dependent reduction of 25-DKG to 2-KLG.The michaelis-menten constant(Km) for 2,5-DKG and NADPH were 0.29 mmol/L and 14.7 mmol/L respectively.The enzyme is specific for NADPH and 2,5-DKG,1 mmol/L Cu~(2+) or Zn~(2+) could highly inhibited the enzyme activity.EDTA and ?-Mercaptoethanol have no effect on the enzyme activity.

Objective to reveal the research situation about food safety in China by analysing the articles published from 2000 to 2008. Methods bibliometrics were used to analyze the articles. The cooperation and the distribution of foundations were searched out from CBMdisc ( China scientific journal Database) with "food safety" as keywords. Results 1829 documents and 4,063 authors were identified. The rate of cooperation was 68.05% and the authors came from 32 provinces, autonomous regions and special administrative regions of China. 194 papers were supported by various kinds of fund. Conclusion Research on food safty is developing fast to meet the soring needs in this respect of the society.

Objective To study the therapy of clearing away the hemorrhagic and necrotic polyps of maxillary sinus.Methods Twenty-five cases,which were diagnosed as hemorrhagic and necrotic polyps of maxillary sinus were treated by surgery of nasal endoscopy with the use of double electrocoagulate and shave system and the surgery of cutting-off front wall of maxillary sinus.Results There is no complication after 6 ～24 months followup.The cure rate is 100% and the recurrence rate is 0.Conclusion The method has the advantage of clearing away the hemorrhagic and necrotic polyps of maxillary sinus with high cure rate.
