Molecular phylogeny and morphology reveal four new species of (Thelephorales, Basidiomycota) from subtropical China, closely related to .

The genus of is a group of cosmopolitan ectomycorrhizal fungi with basidiocarps of morphological diversity that has an extremely scarce species reported from the forest ecosystem in China. In this study, phylogenetic analyses of species from subtropical China were carried out based on multiple loci including the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), and the small subunit of mitochondrial rRNA gene (mtSSU). Maximum likelihood and Bayesian analyses were used to construct the phylogenetic tree.

[Therapeutic effect of Actovegin on acute oral mucositis caused by radiotherapy].

PURPOSE： To explore the clinical effect of Actovegin in the treatment of acute oral mucositis in patients with radiotherapy. METHODS： One hundred and thirteen patients with acute oral mucositis caused by radiotherapy for nasopharyngeal carcinoma admitted to the Department of Oncology, the Fifth People's Hospital of Qinghai Province from July 2015 to September 2017 were randomly divided into the experimental group (57 cases) and control group (56 cases). Patients in the experimental group were treated with Aiweizhi, while patients in the control group were treated with new rehabilitation.
