OBJECTIVE:To understand the application of proprietary Chinese medicine by clinicians in integrated medical insti-tutions,and provide reference for its rational use. METHODS:The questionnaire was designed,including related issues of proprie-tary Chinese medicine clinical application(such as medication basis of proprietary Chinese medicine,combined medication,clini-cal efficacy and its influencing factors,medication for special groups and so on)and suggestions;the questionnaires were delivered to the clinicians who worked in some second and third grade of integrated medical institutions located in southwestern regions and Chengdu,and the questionnaires was in the form of an anonymous;relevant data of available questionnaire were collected statisti-cally;the application situation of proprietary Chinese medicines and the existence question were analyzed,and suggestions were put forward. RESULTS:Totally 300 questionnaires were sent out,264 were effectively received,with effective rate of 88.0%. The clinicians involved in investigation were mainly in undergraduate,mostly the resident physicians and attending physician;only 6.8%of the physicians received the training of basic theory of traditional Chinese medicine after work;36.4%physicians often pre-scribe proprietary Chinese medicines,and the medication basis was mainly in package insert (64.0%) and clinical experience (55.3%);51.1% thought unclear indications affected the application of proprietary Chinese medicines,64.0% thought package in-sert can not meet clinical needs. In terms of answers in brief questions,the surveyed clinicians generally considered the package in-sert was too simple,which needed further perfected. CONCLUSIONS:The problems in clinical application of proprietary Chinese medicines should not be ignored. The relevant departments should strengthen the supervision of clinical application of proprietary Chinese medicines,and strengthen the re-evaluation of proprietary Chinese medicines market,as to provide data support for the continuous improvement of package insert. Medical institutions should carry out training timely for the physicians who prescribe pro-prietary Chinese medicines,the pharmacists should strengthen checking of proprietary Chinese medicines prescription and special prescription comment,and ensure prescription checking and comment play a active role in promoting rational drug use based on“proprietary Chinese medicines clinical application guiding principle”“prescription management method”.

This study was designed to prove simultaneously blocking both EGFR and COX-2-medi-ated pathways may be an efficient means of inhibiting cancer cell growth in NPC. Method: A combination of tarceva (EGFR-selectivetyrosine kinase inhibitors) with celecoxib(Cox-2 inhibitor) was studied on its effects on cell growth, cell cycle progression, apoptosis and protein expression in CNE-2 cell lines by cell growth assay, flow cy-tometric analysis assay and Western blotting. Result: ①The inhibition rate of cell growth was higher in the group treated with a combination of two agents than that the sum of rates of the two groups treated with only one agent (P<0.05). ②The combination of tarceva with celecoxib significantly induced G_1 arrest(P<0.05) ,but did not in-crease apoptosis rate(P>0.05). ③The group of combination showed less expressions of p-EGFR and COX-2 than any other group. Conclusion Simultaneously blocking EGFR and COX-2 mediated pathways would significantly in-hibit the growth of CNE-2 cell line, increase G_1 arrest and reduce the expression levels of p-EGFR and COX-2.

RESULT: (1) The inhibition rate of cell growth was higher in the group treated with a combination of two agents than that the sum of rates of the two groups treated with only one agent (P < 0.05). (2) The combination of tarceva with celecoxib significantly induced G1 arrest (P < 0.05), but did not increase apoptosis rate (P > 0.05). (3) The group of combination showed less expressions of p-EGFR and COX-2 than any other group. CONCLUSION Simultaneously blocking EGFR and COX-2 mediated pathways would significantly inhibit the growth of CNE-2 cell line, increase G1 arrest and reduce the expression levels of p-EGFR and COX-2.
