OBJECTIVE:To establish the method for content determination of?-Schisandrin in Lingzhi granules.METH_ ODS:HPLC method was adopted and a C 18 column was used.The mobile phase was acetonitrile-0.1%H 3 PO 4 of water solution(67∶33).The detection wavelength was at254nm.RESULTS:The calibration curve of?-Schisandrin was linear in the range of0.0816?g～0.816?g(r=0.9999),and the average recovery was99.21%(RSD=0.79%).CONCLUSION:The method is simple and accurate,and can be used for the quality control of Lingzhi granule.

OBJECTIVE:To research how to successfully convert prescribed drug into OTC and to predict the conversion prospect.METHODS:Several prescribed drug-OTC conversion cases in some countries of the world were introduced and the reasons for success or failure were analyzed.RESULTS & CONCLUSIN:The strategy of successful conversion of prescribed drug into OTC is recommended.The conversion prospect depends on the future development trend of a series of factors.

OBJECTIVE: To provide referrences for the state drug administrations strengthening supervision and administration, and also for the pharmaceutical enterprises develeping drug marketing.METHODS: To explain the concept of DTC marketing.And the present situation of drug DTC marketing in several foreign countries were discussed and its development process and existing problems in these countries were also analyzed. RESULTS: Drug DTC marketing was under development in the world and pharmaceutical enterprises hawe showed increasing interest in it, however, drug DTC marketing needed further standardization and improvement. CONCLUSION: Drug DTC marketing holds a promising prospect, the effective and standardized development of it will be a big challenge to state drug administrations and pharmaceutical companies in the world.

The special anatomy around the head of pancreas leads to difficulties in arriving at a definitive diagnosis for a pancreatic head mass,the management of which has recently become a hot topic and a challenge for clinicians.Despite recent advances in tumor markers,ultrasound,CT,PET/CT and MRI,some of these pancreatic head masses cannot be diagnosed with certainty.A fine needle aspiration biopsy can be used before operation; however,false negative results not infrequently happen.Based on the reports from domestic and foreign medical literatures published recently,this paper reviewed and discussed the proper treatment strategies when biopsy results from a pancreatic head mass turn out negative.

Objective:To discuss the dynamic three-dimensional reconstruction of tissue Doppler ultrasound cardiac image.Methods: To separate anatomical structure and function parameter information from Doppler ultrasound medical image, and then combines with the three-dimensional distribution to reconstruct it and fuse imaging.Results: Ultimately, it reveals the relationship between function parameter and anatomical structure. The dynamic three-dimensional reconstruction of tissue Doppler ultrasound cardiac image is also expounded in this paper.Conclusion: It scientifically completed the dynamic three-dimensional reconstruction of tissue Doppler ultrasound cardiac image by combining both tissue Doppler imaging and ultrasound medical image reconstruction technique. It is of great significance in clinical medicine.

With continuous research of the formation mechanism of chronic pancreatitis with mass in the head of the pancreas and its relation with pancreatic cancer,and steady improvement of the operation safety,the number of operation for the chronic pancreatitis with mass in the head of the pancreas is increasing.On the other hand,with the improvement of the accuracy of preoperative diagnosis,Tru-cut intraoperative biopsy is increasingly applied to patients with negative results of preoperative ultrasonography biopsy,which is important for the surgical procedure selection.With the premise of effective treatment,continous improvement of treatment strategies to the chronic pancreatitis with mass in the head of the pancreas can maximize the benefit of patients.

Objective]Training students to consult literature, teamwork, language expression, report writing and other aspects of the ability to develop professionalism, improve the overall quality.[Methods] We review reflections of the current situation on teachingChinese Medical Historycurriculum, put forward a set of time as the main line, physicians investigating and studying as the center, set questionnaires, group discussions, class reporting, comprehensive evaluation of integrated interactive solutions.[Results] By strengthening the self-study and discussion, to stimulate students' enthusiasm for learning and exploration, so that students master the initial medical history of the life, works and academic achievements, for the future in-depth study of traditional Chinese medicine professional knowledge and lay a good foundation. [Conclusion] After preliminary practice, it achieved good results, to be promoted in Tianjin University of Traditional Chinese Medicine.
