Targeting DUSP16/TAK1 signaling alleviates hepatic dyslipidemia and inflammation in high fat diet (HFD)-challenged mice through suppressing JNK MAPK.

Nonalcoholic fatty liver disease (NAFLD) is featured by hepatic steatosis, insulin resistance, lipid deposition and inflammation. However, the pathogenic mechanism of NAFLD is still poorly understood. Dual-specificity phosphatase 16 (DUSP16), a c-Jun N-terminal kinase-specific phosphatase, has been reported to negatively modulate the mitogen-activated protein kinases (MAPKs) signaling, and it has never been investigated in NAFLD progression.

[Effect of fibrous root extract of Coptis chinensis on soil microbes and enzyme activities].

Coptis chinensis is widely used as Chinese medicine herbs and serious soil problems occur after continual cultivation of this medicinal plant. In the preset experiment, fibrous root extract of C. chinensis (REC) was added into soil to study the effect of REC on microbes and enzyme activity in soil.

[Study on optimal harvest period of Lonicera Flos (Lonicera macranthoides)].

To ascertain the optimal harvest period of Lonicera Flos (Lonicera macranthoides) the configuration yield and quality of L. macranthiodes bloom verity and bud verity flower at different develop periods were Observed. The quality of L.

[Effect of fertilization on phenolic components and antioxidant activities of Artemisia annua].

Objective: A pot experiment with variable fertilizer treatments was carried out to study the influence of fertilization on the concentration and accumulation of polyphenols, scopoletin, chrysosplenol-D and chrysosplenetin in roots, stems and leaves and their antioxidant activities. The main aims were to fertilize scientifically in cultivation of Artemisia annua and improve the quality of the harvest organs.

Method: These active components in leaves, stems and roots in the squaring stage were analyzed by HPLC and antioxidant activities of the extracts were evaluated by ultraviolet visible light colorimetric method.

[Allelopathic effect of artemisinin on green algae].

To study the growth effects of differing concentrations of artemisinin on green algae and to evaluate the ecological risk. The effects of artemisinin on the growth and the content change of chlorophyll, protein, oxygen, conductivity, SOD, CAT, MDA in Chlorella pyrenoidosa and Scenedesmus oblique were studied through 96 h toxicity tests. Artemisinin accelerated the growth of algae at a lower concentration ( <40 microg .

[Interspecific association of companion species in Artemisia annua community in southwest of China].

The interspecific association of companion species in Artemisia annua community in 48 region of southwest China was analyzed by variance analysis, chi2-test and association indices. The total related variance ratio among species in A. annua community was 2.

[Allelopathic effects of extracts from fibrous roots of Coptis chinensis on two leguminous species].

An experiment was carried out to study the allelopathic effects of Coptis chinensis fibrous root extracts (CRE) on the germination and seedling growth of Vicia faba and Pisum sativum in order to alleviate the allelopathic effects and increase land productivity. The seeds of both garden pea (P. sativum) and broad been (V.
