ABSTRACT
Hypoxia is an important basic feature of the solid tumor microenvironment. With the deepening of the research on the pathogenesis of renal cell carcinoma (RCC), the expression and function of hypoxia and hypoxia inducible factor (HIF) in RCC have attracted more and more attention. The hypoxia signal pathway has become a research hotspot of tumor and other diseases in recent years. This article reviews the current understanding of hypoxia signal pathway, its correlation with the occurrence and development of RCC, and the application prospect of HIF inhibitors, in order to guide the precise treatment of clinical RCC.
ABSTRACT
Dendrobium officinale is a kind of precious Chinese herbal medicine, which has good effects on the anti-aging, antineoplastic, and blood glucose reducing treatment. It has been listed in the top of “Nine Magic Herbs”, with significant cultural features of traditional Chinese medicine (TCM). Planting, processing, and cultural base construction of Dendrobium officinale in Hunan Province have obtained great achievements. Further combination of Dendrobium officinale with TCM culture will develop a series portable and convenient tourism products with the features of wide taking habits and large intended population. The planting of Dendrobium officinale should be integrated with ecofallow organically; the construction of science museums about Dendrobium officinale should be improved; the modern view on health maintenance “Health maintenance should focus on Yin nourishment” should be included in TCM cultural tourism in Hunan Province. All of these can improve the potential of tourism product development, meet the living requirements of modern people, and drive the development of tourist industry in Hunan Province.
ABSTRACT
Objective To observe the bacteriostatic effect of single herbs, traditional complex prescription and ultra-micro powder of Qiweibaizhusan. Methods The inhibiting zone and MIC of single herb and compound of Qiweibaizhusan on Escherichia coli, Staphylococcus aureus, Eubacterium aerofaciens, Pseudomonas aeruginosa, Salmonella sp, Saccharomyces cerevisiaes and Candida glabrata were measured by filter paper method. Results The growth of the tested bacteria and yeast except Staphylococcus aureus and Salmonella sp were inhibited by ginseng. The antibacterial effect of licorice was the best, and only Pseudomonas aeruginosa’s growth was not inhibited by licorice. The growth of Staphylococcus aureus and Eubacterium aerofaciens were inhibited by Agastache rugosa. The growth of Escherichia coli, Staphylococcus aureus, Eubacterium aerofaciens and Pseudomonas aeruginosa were inhibited by Poria cocos. Only Eubacterium aerofaciens’s growth was inhibited by Radix aucklandiae and fried Atractylodes macrocephala. The growth of all the bacteria and yeast were not inhibited by Radix puerariae. The growth of Staphylococcus aureus, Eubacterium aerofaciens and Salmonella sp were inhibited by the traditional decoction and ultra-micro powder of complex prescription of Qiweibaizhusan, and all the MIC of ultra-micro powder were smaller than the traditional decoction. Conclusion The main antibacterial component of Qiweibaizhusan was ginseng and licorice. The inhibiting effect of ultra-micro powder on bacteria was better than traditional decoction of Qiweibaizhusan in vitro.
