Objective:To understand the cognitive differences and its influential factors of medical dispute and physician′s professionalism between medical personnel and patients, and further to provide evidence for the preven-tion and treatment of medical dispute. Methods:In the case of quality control, we surveyed on the cognitive of medical dispute and physician′s professionalism in medical personnel and patients using self-designed question-naire. Stratified cluster sampling method was used in this study, which recruited 847 medical workers and 577 pa-tients. Data analysis was conducted with SPSS 16. 0. The two sample rates were compared using Chi squaretest (α=0. 05). Results:There is a statistically significance in doctor-patient relationship evaluation, dispute pre-vention, dispute responsibility, fair treatment,impact on the doctors and patients, causes of medical disturbance, attitude tomedical disturbance, medical disturbance elimination, physician′s professionalism evaluation, improve-ment approach, and the physician′s professional value between the two samples, having a direct impact on the con-struction of physician′s professionalism. Conclusion:For medical personnel, they should strengthen the construc-tion of physician′s professionalism and establish effective mechanism to prevent medical dispute. For patienes, they should understand, trust and respect the doctors, and solve medical dispute rationally. For government, they should establish a reasonable mechanism for the settlement of medical dispute, create a rational atmosphere respon-ding to the medical dispute, and reduce the intensification of medical dispute.

OBJECTIVE:To explore the content variation rule and influencing factors of 5-hydroxymethylfurfural(5-HMF)in the extraction process of the herbs Schisandra chinensis and improve the quality of monitoring the extract of Schisandra chinensis. METHODS:High performance liquid chromatography was adopted to determine the contents of 5-HMF in the extracts during the extraction process (decoction,vacuum concentration,alcohol precipitation,vacuum drying,alkali adjustment),and the content variation rule was found out. For vacuum drying during which the content of 5-HMF reduced obviously,the effects of the tempera-ture and time of drying on the content of 5-HMF were studied,and the effects of vacuum drying and freeze drying on the 5-HMF contents were compared. RESULTS:The content variation trend in the extraction process of Schisandra chinensis was as follows as a large amount of 5-HMF was produced in the herbs decoction process;the content of 5-HMF increased during concentration,re-duced during the alcohol precipitation and the vacuum drying of the extracts by three times concentrate,and maintained substantial-ly unchanged during alkali adjustment. In the process of vacuum drying,the content of 5-HMF decreased with temperature rise and time extension. Freeze drying had no effect as good as that of vacuum drying in the reduction in the content of 5-HMF. CON-CLUSIONS:It is suggested that the vacuum drying of the extracts by three times concentrate at higher temperature,which may pro-duce the extract of Schisandra chinensis with lower content of 5-HMF and thus improve the quality of Schisandra chinensis extract.

The main ingredients of Ophiopogonjaponicas include steroidal saponins,flavonoids,polysaccharides,and so on,but the research on polysaccharides is relatively less.This particle will mainly review the chemical composition,analytical methods,and pharmacological effects of Ophiopogon polysaccharides.The Ophiopogon polysaccharides contain a variety of substances,such as MDG-1,Md-1,Md-2,OJP-1,etc;The main analysis methods were sulfuric acid method,phenol-sulfuric acid method,3,5-dinitrosalicylic acid (DNS) colorimetric method,and near-infrared spectroscopy combined with partial least squares regression method.Ophiopogon polysaccharides can effectively improve the cardiovascular system diseases,with antihypoxia,anti-inflammatory,antitumor,anti-oxidation,and other pharmacological effects.
