Yin-chen Wu-ling powder alleviate cholestatic liver disease: Network pharmacological analysis and experimental validation.

Background: Yin-chen Wu-ling Powder (YWP) has potential therapeutic effects on cholestatic liver disease (CLD), however, its active compounds and conceivable mechanism are as yet indistinct.

Methods: The network pharmacology and gene function annotation examined the multiple active ingredients, potential targets, and possible mechanisms of YWP in CLD treatment. Then the molecular docking reassured the reliability of the core compounds including the key genes and farnesoid X receptor (FXR).

Coexistence of SFO-1 and NDM-1 β-lactamase genes and fosfomycin resistance gene fosA3 in an Escherichia coli clinical isolate.

This study aims to characterize antimicrobial resistance and antimicrobial resistance genetic determinants of an Escherichia coli clinical isolate HD0149 from China in 2012. This strain displayed high-level resistance to cephalosporins, carbapenems, fluoroquinolones, aminoglycosides and fosfomycin. A range of antimicrobial resistance genes was detected responsible for its multiple antimicrobial resistances, involving the blaCMY-2, blaCTX-M-65, blaNDM-1, blaSFO-1, blaTEM-1, fosA3, rmtB, sul1 and sul2 genes.

A randomized controlled trial comparing total glucosides of paeony capsule and compound glycyrrhizin tablet for alopecia areata.

Objective: To observe the efficacy and safety of total glucosides of paeony capsule (TGPC) in patients with mild and moderate alopecia areata.

Methods: A total of 86 outpatients were randomly allocated into two groups of TGPC (treatment, 44 cases) and compound glycyrrhizin tablet (control, 42 cases). The treatment group was given oral TGPC, three times daily and 600 mg per time; the control group was given oral compound glycyrrhizin tablets, three times daily and 50 mg per time.

[Effects of Ag nanocrystals on electroluminescence in Si oxide films].

Ag nanocrystal-embedded silicon oxide (SiO2 : Ag) films with varying Ag fractions were prepared on p-Si substrate by magnetron co-sputtering and thermal annealing. Visible electroluminescence (EL) was observed from the structures of ITO/SiO2 : Ag/p-Si. The authors found that Ag nanocrystals in the SiO2 film can not only shift the EL peak evidently but also enhance the EL intensity markedly.

Effect of Chinese herbal medicine combined with acitretin capsule in treating psoriasis of blood-heat syndrome type.

Objective: To observe the clinical curative effect of Chinese herbal medicine combined with acitretin capsule in treating psoriasis of blood-heat syndrome (P-BH).

Methods: Eighty patients of P-BH were randomly assigned to two groups, 39 in Group A and 41 in Group B. Both was treated with Chinese herbal medicines for clearing heat, cooling blood and removing toxic substance, and acitretin capsule was given to Group A additionally, with 8 weeks as one therapeutic course.

From trifluoroacetate complex precursors to monodisperse rare-earth fluoride and oxyfluoride nanocrystals with diverse shapes through controlled fluorination in solution phase.

We report the first systematic synthesis of monodisperse rare-earth (RE=La to Lu, Y) fluoride and oxyfluoride nanocrystals with diverse shapes (trigonal REF3 triangular, truncated-triangular, hexagonal, and polygonal nanoplates; orthorhombic REF3 quadrilateral and zigzag-shaped nanoplates; cubic REOF nanopolyhedra and nanorods) from single-source precursors (SSP) of [RE(CF(3)COO)(3)] through controlled fluorination in oleic acid (OA)/oleylamine (OM)/1-octadecene (ODE). To selectively obtain REF3 or REOF nanocrystals, the fluorination of the RE-O bond to the RE-F bond at the nucleation stage was controlled by finely tuning the ratio of OA/ODE or OA/OM, and the reaction temperature. For phase-pure REF3 or REOF naocrystals, their shape-selective syntheses could be realized by further modifying the reaction conditions.

Selective synthesis of monazite- and zircon-type LaVO(4) nanocrystals.

Pure monoclinic (m-) and tetragonal phased (t-) LaVO(4) nanocrystals could be obtained by a hydrothermal method in a controllable way with additives. It is found that chelating ligands, such as ethylenediaminetetraacetic acid [EDTA or H(4)L, where L(4-) = (CH(2)COO)(2)N(CH(2))(2)N(CH(2)COO)(2)(4-)], favor the formation of t-LaVO(4) and can induce the polymorph transformation from stable m-LaVO(4) to metastable t-LaVO(4). Further studies demonstrated the important roles of chelating ligands in this transformation process.

High-quality sodium rare-earth fluoride nanocrystals: controlled synthesis and optical properties.

We report a general synthesis of high-quality cubic (alpha-phase) and hexagonal (beta-phase) NaREF4 (RE: Pr to Lu, Y) nanocrystals (nanopolyhedra, nanorods, nanoplates, and nanospheres) and NaYF(4):Yb,Er/Tm nanocrystals (nanopolyhedra and nanoplates) via the co-thermolysis of Na(CF3COO) and RE(CF3COO)3 in oleic acid/oleylamine/1-octadecene. By tuning the ratio of Na/RE, solvent composition, reaction temperature and time, we can manipulate phase, shape, and size of the nanocrystals. On the basis of its alpha --> beta phase transition behavior, along the rare-earth series, NaREF4 can be divided into three groups (I: Pr and Nd; II: Sm to Tb; III: Dy to Lu, Y).

Self-organized monolayer of nanosized ceria colloids stabilized by poly(vinylpyrrolidone).

Four nanometer colloidal ceria nanocrystals in a fluorite cubic structure have been synthesized via an alcohothermal treatment at 180 degrees C for 24 h from Ce(NO(3))(3)*6H(2)O in ethanol, using various alkylamines including triethylamine, butylamine, and hexadecylamine as the bases and poly(vinylpyrrolidone) (PVP) as the stabilizer. They were characterized by multiple measurements of X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), ultraviolet visible (UV-vis) spectroscopy, dynamic light scattering (DLS), and infrared spectroscopy (IR). The introduction of PVP could effectively stabilize the cerium nuclei against self-aggregation and finally lead to the formation of the CeO(2) colloids.

Hierarchical assembly of SnO2 nanorod arrays on alpha-Fe2O3 nanotubes: a case of interfacial lattice compatibility.

SnO2 nanorod arrays were hierarchically assembled onto the surface of alpha-Fe2O3 nanotubes via a facile solution method. Determined by the hexagonal geometrical nature of the alpha-Fe2O3 nanotubes, the heterostructures were of 6-fold symmetry. HRTEM characterizations demonstrated that the lattice mismatch at the interface was an important factor in determining the growth direction of the secondary nanorod arrays.
