[Evaluation of methodological and reporting quality of domestic clinical guidelines for hyperuricemia].

This study aims to evaluate the methodological and reporting quality of diagnosis and treatment guidelines for hyperuricemia as well as the expert consensuses and promote the understanding and application of the diagnosis and treatment guidelines for hyperuricemia. With "hyperuricemia" "guidelines" "consensus" "recommendations" as the key words in titles, the authors searched for the published clinical guidelines on hyperuricemia in Chinese against CNKI, Wanfang, VIP, Medlive and the official website of the industry association. The retrieval time limit was until May 31, 2021.

Preparation and investigation of CaZr4(PO4)6:Dy(3+) single-phase full-color phosphor.

A novel single-phase full-color phosphor CaZr4(PO4)6:Dy(3+) has been synthesized by a high-temperature solid-state reaction. X-ray powder diffraction (XRD) analysis and FT-IR spectra confirmed the phase formation of CaZr4(PO4)6:Dy(3+) materials. The photoluminescence excitation and emission spectra, the concentration dependence of the emission intensity, decay curves, ultraviolet-visible absorption spectroscopy and Commission International de I(')Eclairage (CIE) of the phosphor were investigated.

Dihydromyricetin inhibits migration and invasion of hepatoma cells through regulation of MMP-9 expression.

Aim: To investigate the effects of dihydromyricetin (DHM) on the migration and invasion of human hepatic cancer cells.

Methods: The hepatoma cell lines SK-Hep-1 and MHCC97L were used in this study. The cells were cultured in RPIM-1640 medium supplemented with 10% fetal bovine serum at 37 °C in a humidified 5% CO2 incubator.

Nanosized metal oxide and nanobelts prepared by selective dealloying of Ti-based amorphous powders.

Two typical nanomaterials, nanosized metal oxides and nanobelts, are obtained in one-pot selective dealloying process by using multiple-component Ti-based amorphous powders as dealloying precursors. The microstructure and photoelectric conversion property of the as-synthesized Zr-doped nanobelts are comprehensively investigated. Particularly, a core-shell structure, for example, residual amorphous alloy as the microsized core and nanosized metal oxide composites (mainly TiO2 and CuO) as the shell, forms as a byproduct of the selective dealloying.

Neuropeptide Y Gene Promoter -399T/C Polymorphism Increases Risk of Ischemic Stroke.

Background: Several genetic factors underlying ischemic stroke have been identified. Variants of Neuropeptide Y (NPY), whose product plays diverse roles in modulating physiological functions, have been associated with an increased risk of ischemic stroke in South Korean individuals.

Aims: We explored the association between a polymorphism in the NPY gene promoter at position -399 and the risk of ischemic stroke in Han Chinese.

[The intercostal nerve transplantation with olfactory ensheathing cells modified by NGF, BDNF genes repairs the injured rat spinal cord].

Objective: To study the repairable effects of intercostal nerve transplantation with NGF,BDNF genes modifying olfactory Ensheathing cells (OECs) on spinal cord injury (SCI).

Methods: The spinal cord hemisection model was made by cutting 2 mm rat spinal cord from T11 and T12. And then the lesion was repaired using intercostal nerve linking manner (proximal gray substance to distal white substance and L1, L2, L3, L4 of radix posterior and proximal white substance), and with NGF, BDNF genes modifying OECs were transplanted into group A.
