ABSTRACT
Emerging evidence has demonstrated the vital role of metabolism in various diseases or disorders. Metabolomics provides a comprehensive understanding of metabolism in biological systems. With advanced analytical techniques, metabolomics exhibits unprecedented significant value in basic drug research, including understanding disease mechanisms, identifying drug targets, and elucidating the mode of action of drugs. More importantly, metabolomics greatly accelerates the drug development process by predicting pharmacokinetics, pharmacodynamics, and drug response. In addition, metabolomics facilitates the exploration of drug repurposing and drug-drug interactions, as well as the development of personalized treatment strategies. Here, we briefly review the recent advances in technologies in metabolomics and update our knowledge of the applications of metabolomics in drug research and development.
ABSTRACT
Objective:To analyze the current situation of the course of Pharmaceutical Analysis in the education and training of undergraduate students, explore the teaching reform and innovation to better accommodate the pharmacy education in the new era and build an advanced mode for training pharmaceutical talents with interdisciplinary expertise that meet the requirements and needs of job market. Methods:The first stage was to investigate the suggestions and needs of teaching reform; the second stage was to carry out the exploration and practice of the course reform; the third stage was to evaluate the teaching effect.Results:The demand survey showed that the teaching content, course design, and teaching methods of the Pharmaceutical Analysis need to be further optimized and expanded. Conclusion:By adjusting the teaching content, expanding teaching methods, innovating diversified teaching practices, and integrating the "curriculum ideology and politics" into the construction, the course reform has stimulated students' interest in learning and innovative spirit, strengthened their theoretical literacy and practical ability, and cultivated their international vision and lofty professional ethics.
ABSTRACT
Patients diagnosed to have acute coronary syndromes( ACS) were included in the study. All ACS patients were divided into non-diabetes group(40 cases) and diabetes group(80 cases) . Blood coagulation function was de-termined for all patients. In the diabetes group eighty patients were randomly divided into ticagrelor group (48 ca-ses) and clopidogrel group (32 cases) . After 5 days′treatment, platelet function was detected. Our study aimed to examine the effects of ticagrelor and clopidogrel on the platelet function.
ABSTRACT
BACKGROUND:Hepatocyte growth factor(HGF) is a kind of multifunctional growth factor,which can accelerate cell growth,transition and genesis in various organs.In cardiovascular system,HGF has reported to have anti-apoptotic,anti-fibrotic,as well as repair endothelial cell injury effects,suppose that HGF has relationships with hypertension.OBJECTIVE:To investigate the effect of HGF on blood pressure,vascular endothelial system and renin-angiotensin system(RAS) in spontaneously hypertensive rats,further more,to discuss the mechanisms between HGF and hypertension.DESIGN,TIME AND SETTING:The randomized control experiment on animal was performed at the Department of Cardiology,First Affiliated Hospital of Anhui Medical University from March to July 2007.MATERIALS:The exogenous HGF power was purchased from America Peprotech Company.Rats with 14-weeks-old,weighting 200-250 g,were randomly divided into the experimental and spontaneous hypertension groups,WKY rats were serves as the control group,with 12 animals in each group.METHODS:Rats in the experimental group were administrated 5,10,15,20,and 25 ?g/kg HGF per 24 hours,the partes aequales sodium chloride was injected into the spontaneous hypertension and control groups.Five minutes after administration,systolic pressure and heart rates were measured.The rats were sacrificed and harvested 2 mL blood of right ventricle when blood pressure decrease the lowest,about 30 minutes after administration.MAIN OUTCOME MEASURES:The effect of HGF on systolic pressure and heart rates,and levels of serum nitrogen monoxidum(NO),plasma endothelin(ET),as well as angiotensinⅡ(Ag Ⅱ) were detected by colorimetry and radio-immunity methods.RESULTS:When injected 5?g/kg HGF,the blood pressure did not significantly change.After 10 ?g/kg HGF injection,the blood pressure began to decrease and reached a peak after 30 minutes,gradually recovered after 1 hour,and back to the normal after 5 hours.Injection of 20 ?g/kg has largest effect on rats,with reduced contractive pressure 40-50mmHg,but no significantly changes appeared by adding HGF dose.There were no significantly differences of heat rate and blood pressure between the two control groups.Compared with the spontaneous hypertension group,the levels of ET and AgⅡ were decreased,however,the level of NO was increased(P
