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.

[Conclusion] After preliminary practice, it achieved good results, to be promoted in Tianjin University of Traditional Chinese Medicine.

Primary biliary cholangitis (PBC)is a commonly seen cholestatic liver disease.Currently,ursodeoxy-cholic acid (UDCA)is the only drug approved for the effective treatment of PBC.However,up to 40% of PBC patients had poor response to UDCA.Farnesoid X receptor (FXR)can inhibit the synthesis of bile acid,regulating the transport of bile acid and playing a role in anti-hepatic fibrosis.This article reviewed the role of FXR in treatment of PBC.

OBJECTIVE: To establish a RP-HPLC method for the determination of the content of Emodin in Fugan oral liquid.METHODS: The sample was separated on Zorbax SB-C18 column(150 mm?4.6 mm,5 ?m) with methanol-0.1%phosphoric acid solution(85∶15) as the mobile phase at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 430 nm and the column temperature was 30 ℃.RESULTS: The calibration curve was linear at a range of 0.075 2 mg～0.376 0 mg(r=0.999 96) for the Emodin.The average recovery was 99.77% and the related standard deviation(RSD) was 1.03%(n=6).CONCLUSION: This method was proved to be simple,quick and reproducible and can be used for the quality control of Fugan oral liquid.

Objective To investigate the clinical manifestations and diagnosis and treatment of aortic dissection(AD).Methods The clinical data of 20 patients with aortic dissection were analyzed retrospectively.Results 20 patients were diagnosed by CT, MRI and colour ultrasonography (5,5,10 cases, respectively). According to DeBakey typing, this group of patients was composed of type I(11 cases, 55%), type II(2 cases, 10%)and type III (7 cases, 35%). All patients were treated with internal medicine ,average time in hospital stay was(29 8?25 5)days. The patients' conditions were improved in 19 person-times (76%). 4 patients died (20%) and 2 patients abandoned treatment (8%).Conclusions The accurate diagnosis as early as possible and active therapy was a key of improvment of prognosis in patients with aortic dissection.

OBJECTIVE:To provide references for how to enhance industrial technical level and research&development ability.METHODS:The status quo of the research&development and the investment of the multinational pharmaceutical enterprises in China,and the motive and impact of their increased investment in China were studied and analyzed.Some countermeasures and recommendations in coping with the international economical situation were presented.RESULTS&CONCLUSION:Under the situation of increasing investment on research&development in china by multinational pharma-ceutical enterprises,we should take advantage of the positive effects and avoid the negative effects,insist on independence and innovation meanwhile enhance international cooperation so as to promote the development of Chinese pharmaceutical indus-tries.
