[Mechanism of Xianglian Pills in improving dyslipidemia in obese mice induced by high-fat diet based on network pharmacology and intestinal flora].

The present study aimed to investigate the effect of Xianglian Pills(XLP) on lipid metabolism in obese mice and explore the underlying mechanism based on network pharmacology and intestinal flora. Firstly, network pharmacology was used to predict the possible effect of XLP on obesity. Secondly, an obese mouse model induced by a high-fat diet was established to observe changes in mouse body weight, adiposity index, liver and adipose tissue pathology.

[Effect of Morus alba extract sanggenon C on growth and proliferation of glioblastoma cells].

Glioblastoma is the most common primary cranial malignancy, and chemotherapy remains an important tool for its treatment. Sanggenon C(San C), a class of natural flavonoids extracted from Morus plants, is a potential antitumor herbal monomer. In this study, the effect of San C on the growth and proliferation of glioblastoma cells was examined by methyl thiazolyl tetrazolium(MTT) assay and 5-bromodeoxyuridinc(BrdU) labeling assay.

[Secondary metabolites of endophyte fungi Xylaria sp. from Coptis chinensis].

Two new polyketides, lasobutone A(1) and lasobutone B(2), along with three known compounds, guignardianone C(3), guignardic acid(4), and 4-hydroxy-17R-methylincisterol(5), were isolated from the endophytic fungi Xylaria sp. by silica gel, MCI, and preparative HPLC, which was separated from the Chinese medicinal material Coptis chinensis and cultivated through solid fermentation with rice. Their structures were elucidated on the basis of spectroscopic methods, such as MS, NMR, IR, UV, and ECD.

[Research progress on chemical constituents and pharmacological activities of Morus alba].

Morus alba, a traditional economic crop, is also a significant medicinal plant. The branches(Mori Ramulus), leaves(Mori Folium), roots and barks(Mori Cortex), and fruits(Mori Fructus) of M. alba are rich in chemical components, such as alkaloids, flavonoids, flavanols, anthocyanins, benzofurans, phenolic acids, and polysaccharides, and possess hypoglycemic, hypolipidemic, anti-inflammatory, anti-tumor, anti-microbial, liver protective, immunoregulatory, and other pharmacological activities.

[A new polyketide of endophytic fungi Aspergillus sp. ZJ-58 from Coptis chinensis].

A new polyketide, coptaspin A(1), along with two known compounds 4-acetyl-3,4-dihydro-6,8-dihydroxy-3-methoxy-5-methylisocoumarin(2), and cytochalasin Z_(12)(3), was isolated from the endophytic fungi Aspergillus sp. ZJ-58, which was isolated from the genuine medicinal plant Coptis chinensis in Chongqing after solid-state fermentation on rice and silica gel, MCI, and HPLC-based separation. Their structures were elucidated by MS, NMR, IR, UV, and ECD.

[Effects of tetrandrine on proliferation, migration, and invasion of glioblastoma cells].

Glioblastoma is the most common intracranial primary malignant tumor, which leads to the poor quality of life of patients and has a high recurrence rate. Chemotherapy is a vital part in the treatment of this disease. Tetrandrine(Tet) is an active ingredient extracted from the root of the Chinese medicinal plant Stephania tetrandra, which has been proved with a wide range of pharmacological effects including anti-tumor.

[Effect of different fertilization treatments on growth,secondary metabolites,and seed yield and quality of Perilla frutescens].

Perilla frutescens,an annual plant in Labiatae family,is grown throughout China and can be used for medicine purposes and as food additives. The present field experiment was carried out to study the effects of different fertilizer treatments on the concentrations and accumulations of antioxidant components,including flavonoids and polyphenols,growth,seed yields and qualities of this plant.The main aim of this study is to provide farmers some advice for improving the yields and qualities of P.

[Total alkaloids of Coptidis Rhizoma combined with exercise inhibits tumor growth of orthotopically transplanted 4T1 breast cancer mice by blocking cell cycle G_1/S transformation].

Breast cancer is one of the leading causes for cancer-related death among women worldwide. Coptidis Rhizoma has antibacterial,anti-inflammatory,anti-tumor and other pharmacological activities,but whether exercise could synergistically promote the role of RC in the treatment of breast cancer has not been reported. In this experiment,the effects and mechanism of total alkaloids of Coptidis Rhizoma combined with exercise on the tumor growth of orthotopically transplanted 4 T1 breast cancer were systemically studied in mice.

Carbon dots derived from algae as HO sensors: the importance of nutrients in biomass.

Carbon dots produced hydrothermally from algae were used directly for HO sensing. The mineral nutrients in biomass were found be important for the composition, crystallinity, dispersion and photoluminescence (PL) quenching of the carbon dots under reactive oxygen species, which catalysed the oxidation of passivating ligands.

Conservation genetics in Chinese sheep: diversity of fourteen indigenous sheep (Ovis aries) using microsatellite markers.

The domestic sheep (Ovis aries) has been an economically and culturally important farm animal species since its domestication around the world. A wide array of sheep breeds with abundant phenotypic diversity exists including domestication and selection as well as the indigenous breeds may harbor specific features as a result of adaptation to their environment. The objective of this study was to investigate the population structure of indigenous sheep in a large geographic location of the Chinese mainland.

Cuticular waxes in alpine meadow plants: climate effect inferred from latitude gradient in Qinghai-Tibetan Plateau.

Alpine meadow ecosystems are susceptible to climate changes. Still, climate impact on cuticular wax in alpine meadow plants is poorly understood. Assessing the variations of cuticular wax in alpine meadow plants across different latitudes might be useful for predicting how they may respond to climate change.
