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.

0.05). The concentrations of MMP-2 and MMP-9 were significantly increased on days 1, 10, and 30 after percutaneous coronary intervention, and those on day 10 were higher than on day 1 (P

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.

Objective To evaluate endothelium-dependent dilation (flow-mediated dilation, FMD) and endothelium-independent dilation(nitroglycerin-mediated dilation, NMD) of the brachial and superficial arteries in elderly patients with atherosclerotic disease(LEASD) of the lower extremity, and to evaluate the correlation between brachial and superficial femoral FMD and NMD and their characteristics. Methods Both FMD and NMD of the brachial artery and the superficial femoral artery were determined in 33 old LEASD patients with the high-resolution ultrasound, and the results were compared with that of 40 healthy elderly controls and 30 non-LEASD elderly patients with cardiovascular risk factors, respectively. Results Both FMD and NMD of the brachial artery and the superficial femoral artery were significantly lower in 33 elderly LEASD patients compared with those of 40 healthy elderly controls and 30 non-LEASD elderly patients but with cardiovascular risk factors (P

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.

This paper aimed to introduce and review the antioxidant and material base of selaginella medicinal plants.On the basis of the systematic identification of selaginella medicinal plants,we found that the ethyl acetate extract and flavonoids could inhibit the activity of XOD,LOX or/and COX-2 to some extent.Fourteen biflavonoids,one flavonoid and five flavonoid glycosides have been isolated from three resource plants,among them five compounds were firstly reported and fifteen compounds were firstly isolated in selaginella plants.Amentoflavone (AME),robustaflavone and robustaflavone-4''-dimethylether are three common characteristic constituents of selaginella plants,which can act as marks of common active ingredients and be applied to evaluate the quality of selaginella.Further studies found that some plants had stronger anti-Coxsackie virus and anti-tumor effects,and their mechanisms were associated with inhibiting multiple oxidase and mitigating harm of free radicals due to whole function.
