Three new polycyclic phenol derivatives, 2-acetyl-4-hydroxy-6H-furo [2,3-g]chromen-6-one (), 2-(1',2'-dihydroxypropan-2'-yl)-4-hydroxy-6H-furo [2,3-g][1]benzopyran-6-one () and 3,8,10-trihydroxy-4,9-dimethoxy-6H-benzo[c]chromen-6-one (), along with seven known ones (-, and ) were isolated for the first time from the leaves of . Their structures were determined by spectroscopic analysis and comparison with literature-reported data. These compounds were tested for their in vitro antibacterial activity against four Gram-(+) bacteria: (), methicillin-resistant (), (), (), and the Gram-(-) bacterium .

Mechanisms of pruritus are implicated in the dysregulation of the metabolites in the spinal cord. We investigated pruritus behavioral testing in three groups of young adult male C57Bl/6 mice, including one group treated with normal saline, while the other groups intradermally injected with α-Me-5-HT (histamine-independent pruritogen), compound 48/80 (histamine-dependent pruritogen) at the nape skin of the neck, respectively. Proton nuclear magnetic resonance spectroscopy (MRS) was used to compare spinal metabolites from the vertebral cervical among three groups, and to study the association of spinal metabolite ratio and pruritus intensity.

The identification of the expression patterns of long non‑coding RNAs (lncRNAs) and mRNAs in the spinal cord under normal and cardiac ischemia/reperfusion (I/R) conditions is essential for understanding the genetic mechanisms underlying the pathogenesis of cardiac I/R injury. The present study used high‑throughput RNA sequencing to investigate differential gene and lncRNA expression patterns in the spinal cords of rats during I/R‑induced cardiac injury. Male Sprague Dawley rats were assigned to the following groups: i) Control; ii) 2 h (2 h post‑reperfusion); and iii)v0.

Background: Whether primary tumor surgery should be performed in breast cancer patients with metastatic disease at diagnosis has been debated for decades. This study aims to evaluate the value of primary tumor surgery with respect to the mortality of patients with stage IV breast cancer and to define the heterogeneity of this population.

Methods: stage IV patients from the Surveillance, Epidemiology and End Results database (SEER) from 2010 to 2015 were included in our study.

Background: We aimed to evaluate the prognostic value of the lymph node ratio (LNR) in patients with axillary lymph node-positive triple-negative breast cancer (TNBC).

Methods: The prognostic efficacy was investigated in the first cohort from the Surveillance, Epidemiology, and End Results (SEER) dataset (n=4114) and was further validated in an independent cohort from Fudan University Shanghai Cancer Center (n=417). Patients were classified into low-, medium- and high-risk LNR groups.

Several studies have shown that CNS provides the regulation of gastric functions. Recent evidence indicated that the activation of melanocortin 4 receptors (MC4R) in brain nuclei played an important role in modulating gastric activity. This study was designed to assess whether MC4R signaling existed in autonomic circuitry modulated the activity of stomach by a virally mediated transsynaptic tracing study.
