(Rubiaceae), a new species from south-western China and northern Vietnam.

, a new species from south-western China and northern Vietnam, is described and illustrated. The new species is characterised by the glabrous surfaces on almost all plant parts, congested inflorescences and broad-ovate to ovate bracts 9-22 × 4-11 mm. It morphologically differs from the closest species, , mainly in most plant parts being glabrous, bracts broad-ovate to ovate, apex acute or sometimes obtuse, corollas inside with a ring of white hairs at the middle and anthers inserted near the middle in long-styled flowers.

Computed Tomography-Guided Percutaneous T4 Thoracic Sympathetic Radiofrequency Thermocoagulation for Primary Palmar Hyperhidrosis: A Retrospective Observational Trial.

Purpose: To evaluate the efficacy, safety, and patient satisfaction of computed tomography (CT)-guided percutaneous T4 thoracic sympathetic radiofrequency thermocoagulation (RFT) for the treatment of primary palmar hyperhidrosis (PPHH).

Materials And Methods: A total of 158 patients who underwent bilateral thoracic sympathetic RFT at the T4 level were analysed. Hyperhidrosis Severity Scale (HDSS), Dermatologic Quality of Life Index (DLQI), patient satisfaction, and adverse events were evaluated within 12 months after RFT.

Sodium aescinate and its bioactive components induce degranulation via oxidative stress in RBL-2H3 mast cells.

Sodium aescinate (SA) is a vital salt of sodium escin from Rehd seeds. SA injection (SAI) has received great success in treating cerebral edema, venous reflux disease and other inflammatory conditions. Recently, high incidences of immediate hypersensitivity reactions were reported after SA infusion, which raised questions on safety and risk associated with its clinical application.

Determination, characterization and cytotoxicity on HELF cells of ZnO nanoparticles.

Three kinds of ZnO nanoparticles (NPs) with different size were characterized with transmission electron microscopy (TEM), X-ray diffraction (XRD). The potential cytotoxicity of ZnO NPs with various concentrations has been investigated using human embryonic lung fibroblasts (HELF) cells. The cytotoxicity of ZnO NPs on the normal HELF cell was evaluated by 3-(4,5-dimethylthiazol)-2,5-diphenltetrazoliumhromide (MTT) assay and characterized with photo microscopy and scanning electron microscopy (SEM).

[Analysis of nine kinds of elements contents in the milk powder by inductively coupled plasma-atomic emission spectrometry].

Objective: To establish a method of determination of nine kinds of elements contents in the milk powder by inductively coupled plasma-atomic emission spectrometry (ICP-AES).

Methods: The milk powder is analyzed by ICP-AES. At the same time, the optimum conditions of digesting and analyzing sample are chosen.
