The extraction of flavonoids is of increasing interest because of their various pharmacological effects. This study is the first attempt for the ultrasonic-assisted enzymatic hydrolysis (USAEH) applied in the extraction of 2 bioactive flavonoid compounds in celery--luteolin and apigenin. The quantitative yields of luteolin and apigenin were determined by(More)
Eucommiae Cortex (Eucommia ulmoides Oliver Bark) has been used for anti-osteoporosis usually as an ethnic drug for hundred years in China. In this study, a bioactive compound, 5-(hydroxymethyl)-2-furaldehyde (5-HMF), was isolated from Eucommiae Cortex. We found that after rat bone mesenchymal stem cells (bMSCs) were induced by 5-HMF at the concentration of(More)
Traditional Chinese medicine can promote the proliferation of bone marrow-derived mesenchymal stem cells (BMSCs). We chose four "Kidney-tonifying" Chinese herbal medicines, Radix Astragali, Salvia, Herba Epimedii, and Saussurea Involucrata, to evaluate whether they had positive effects on the proliferation of BMSCs and TGF-β1-induced chondrogenic(More)
Medical education to international students has become an important part of higher education in China. Medical genetics is an essential and required course for international medical students. However, the internationalization of higher education in China has challenged the traditional teaching style of medical genetics. In this article, we discussed current(More)
BACKGROUND & OBJECTIVE Our previous study found that BALB/c mice are highly susceptible to transplanted SP2/0 tumors, whereas C57BL/6J mice are barely susceptible. This study was to detect genetic modifier loci that would influence the size of transplanted SP2/0 tumors using these two inbred mouse strains and their F2 progenies. METHODS A total of 5x106(More)
