OBJECTIVE: To offer reference for Chinese pharmaceutical enterprises in formulating a physicians' prescription behavior-based marketing strategy. METHODS: A survey and analysis was carried out by reviewing pertinent literature and interviewing experts. RESULTS: Physicians' prescription behavior was influenced by many factors. Most pharmaceutical enterprises had inertia thinking in formulating marketing strategies in that they put an emphasis on the quantity rather than the quality of information available to physicians, which has caused the unsatisfactory sales performance. CONCLUSIONS: The pharmaceutical enterprises could improve the efficiency of sales performance by analyzing physicians' prescription behavior, getting rid off inertia thinking and taking corresponding strategies.

Colonoscopy has been accepted as the standard method for evaluation of colon and rectum,its success rate depends on the quality of bowel preparation. Aims:To evaluate the cleanliness and tolerance of fractionated dose versus single dose polyethylene glycol electrolyte solution( PEG-ES) bowel preparation regimens for colonoscopy. Methods:A total of 427 consecutive asymptomatic individuals undergoing colorectal cancer screening were enrolled and randomly assigned into 2 groups. Subjects in group A drank 1. 5 L PEG-ES on the eve and 4 hours before colonoscopy, respectively;subjects in group B received a single dose of 3 L PEG-ES 5 hours before colonoscopy. Score and degree of Boston bowel preparation scale(BBPS)and PEG-ES related adverse effects of the two groups were assessed and compared. Results:There were no significant differences in gender,age and cecal insertion rate between group A and group B(P ﹥ 0. 05). Score of BBPS was significantly higher in group A than in group B(P ﹤0. 01). Both regimens met the requirement of conventional colonoscopy,however,the cleanliness of colon was graded as excellent in more subjects of group A( P ﹤ 0. 01),and less subjects of group A complained PEG-ES related nausea(P ﹤0. 05). Logistic regression analysis revealed that the PEG-ES drinking pattern was associated with cleanliness of colon and occurrence of nausea( P ﹤ 0. 05). Conclusions:Fractionated dose PEG-ES regimen provides a better colonic cleansing quality and tolerance for bowel preparation of colonoscopy,which is superior to that of single dose regimen.

Objective:To express rationally engineered antibodies against EGFR and assess their affinity to EGFR and anti-tumor cell migration effect. Methods:L and V_H genes of humanized antibodies against EGFR were designed and synthesized. Genes encoding V_H and C_H were connected and then cloned into a pIRES based bicistronic expression vector. Gene encoding the corresponding L gene was also cloned into the same vector. 293T cells were transfected with the recombinant plasmid and the antibody expression was confirmed by Western blotting. The antibodies were purified by protein A based affinity chromatography. Binding of the humanized antibody to the EGFR was assessed by Surface Plasmon Renainance with Biacore3000, and the biological activity of the humanized antibody was determined by tumor cell invasion test.Results:Three expression vectors were constructed and the humanized anti-EGFR antibodies were expressed and purified successfully. In reducing SDS-PAGE, the antibodies exhibited two bands of approximately 25×10~3and 50×10~3, respectively. Western blot assay showed that the humanized antibodies had recognition specificity to goat-human IgG antiserum. Biacore assay revealed that the humanized antibody C3 binds to EGFR with high affinity(6.13×10~(-10)M). Cell migration test showed that C2,C3 and C5 could suppress growth and migration of tumor cells.Conclusion:Three anti-EGFR humanized antibodies (C2,C3 and C5) have been constructed and expressed successfully, and the C3 antibody retained high affinity for EGFR and showed improved inhibitory effect on tumor cell growth and migration.
