Analysis of Risk Factors for Postherpetic Neuralgia in Patients With Postmalignancy Herpes Zoster.

Background: The high risk of developing postherpetic neuralgia (PHN) is associated with severe immunosuppressive diseases. A malignancy itself, as well as surgery, radiotherapy, and other treatments, can lead to changes in the immune status of the body and predispose patients with a malignancy to PHN.

Objective: To investigate the risk factors of postherpetic neuralgia in herpes zoster (HZ) after a malignant tumor and to provide better preventive strategies for clinical practice.

Importance of GWAS Risk Loci and Clinical Data in Predicting Asthma Using Machine-learning Approaches.

Introduction: To understand the risk factors of asthma, we combined genome-wide association study (GWAS) risk loci and clinical data in predicting asthma using machine-learning approaches.

Role of Sensory Pathway Injury in Central Post-Stroke Pain: A Narrative Review of Its Pathogenetic Mechanism.

Central post-stroke pain (CPSP) is a severe chronic neuropathic pain syndrome that is a direct result of cerebrovascular lesions affecting the central somatosensory system. The pathogenesis of this condition remains unclear owing to its extensive clinical manifestations. Nevertheless, clinical and animal experiments have allowed a comprehensive understanding of the mechanisms underlying CPSP occurrence, based on which different theoretical hypotheses have been proposed.

Therapeutic Mechanism of Xiaoqinglong Decoction against COVID-19 Based on Network Pharmacology and Molecular Docking Technology.

Complete plastome sequence of Hook. f. (Hamamelidaceae).

The complete chloroplast genome of (Hamamelidaceae) was firstly reported in this study. The complete chloroplast genome of R. championii is 159,115 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 88,123 bp), a single-copy region (SSC, 18,131 bp) and a pair of inverted repeats (IRs, 26,420 bp).

GSP-2, a polysaccharide extracted from Ganoderma sinense, is a novel toll-like receptor 4 agonist.

Ganoderma sinense is a Chinese unique medicinal fungus that has been used in folk medicine for thousands of years. Polysaccharides are considered to be biologically active ingredients due to their immune-modulating functions. Previously we found that GSP-2, a new polysaccharide isolated from Ganoderma sinense, exerts an immunomodulatory effect in human peripheral blood mononuclear cells but the underlying mechanism is unclear.
