A prognostic four-gene signature and a therapeutic strategy for hepatocellular carcinoma: Construction and analysis of a circRNA-mediated competing endogenous RNA network.

Background: Hepatocellular carcinoma (HCC) has a poor long-term prognosis. The competition of circular RNAs (circRNAs) with endogenous RNA is a novel tool for predicting HCC prognosis. Based on the alterations of circRNA regulatory networks, the analysis of gene modules related to HCC is feasible.

Anti-tumour effect of Huangqin Decoction on colorectal cancer mice through microbial butyrate mediated PI3K/Akt pathway suppression.

Huangqin Decoction (HQD), a Chinese herbal formula, is widely used for various diseases, including colorectal cancer (CRC). We proposed that microbial butyrate mediated PI3K/Akt pathway suppression might involve the anti-cancer effect of HQD. This study aimed to evaluate the potential mechanism of HQD against CRC.

Biliatresone: progress in biliary atresia study.

Background: Biliary atresia (BA) is one of the main causes of neonatal end-stage liver disease. Without timely diagnosis and treatment, most children with BA will develop irreversible liver fibrosis within the first two months. While current theorized causes of BA include viral infection, immune disorders, and genetic defects, the comprehensive etiology is still largely unknown.

Acupuncture for gastrointestinal diseases.

Acupuncture, an important component of traditional Chinese medicine, has gained growing attention around the world in the past decades. Both manual and electroacupuncture are commonly used in clinical practice, especially by patients with gastrointestinal disorders seeking symptoms control due to disease signs recurrence and/or lack of effective treatments. Currently, patients with functional gastrointestinal disorders, constipation, gastroesophageal reflux disease, inflammatory bowel disease, ileus, acute pancreatitis, and gastroparesis may benefit from acupuncture treatment, as clinically evident, and the most frequently used acupoints are chosen from the large intestine, stomach, bladder, and spleen meridian.

The interpretation of human body in traditional Chinese medicine and its influence on the characteristics of TCM theory.

Traditional Chinese medicine (TCM) has a long history of serving the Chinese people's health since its birth, including playing an important role in treating and preventing COVID-19 in 2020. The fact that TCM has been used in China for thousands of years shows the value and reason why it must exist. Although TCM has been or is being questioned, there is no doubt about its importance in terms of efficacy.

Selective activation of TWIK-related acid-sensitive K 3 subunit-containing channels is analgesic in rodent models.

The paucity of selective agonists for TWIK-related acid-sensitive K 3 (TASK-3) channel, a member of two-pore domain K (K2P) channels, has contributed to our limited understanding of its biological functions. By targeting a druggable transmembrane cavity using a structure-based drug design approach, we discovered a biguanide compound, CHET3, as a highly selective allosteric activator for TASK-3-containing K2P channels, including TASK-3 homomers and TASK-3/TASK-1 heteromers. CHET3 displayed potent analgesic effects in vivo in a variety of acute and chronic pain models in rodents that could be abolished pharmacologically or by genetic ablation of TASK-3.

pik3r3b, a novel immune-related gene in Nile tilapia (Oreochromis niloticus): Identification, expression and analysis of antibacterial activity.

A full-length cDNA encoding phosphatidylinositol 3-kinase regulatory subunit gamma b gene in Nile tilapia (Oreochromis niloticus), termed as On-pik3r3b, was identified and characterized in this study. The sequence analysis demonstrated that the full-length cDNA of On-pik3r3b was 2018 bp, containing a 5' untranslated region (UTR) of 171 bp, an open reading frame (ORF) of 1422 bp and a 3' UTR of 425 bp. Its protein sequence displayed a high degree of identity with other fish.

Subtype-selective inhibition of acid-sensing ion channel 3 by a natural flavonoid.

Aims: Acid-sensing ion channels (ASICs) are extracellular proton-gated cation channels that have been implicated in multiple physiological and pathological processes, and peripheral ASIC3 prominently participate into the pathogenesis of chronic pain, itch, and neuroinflammation, which necessitates the need for discovery and development of novel modulators in a subtype-specific manner.

Methods: Whole-cell patch clamp recordings and behavioral assays were used to examine the effect of several natural compounds on the ASIC-mediated currents and acid-induced nocifensive behavior, respectively.

Results: We identified a natural flavonoid compound, (-)-epigallocatechin gallate (EGCG, compound 11), that acts as a potent inhibitor for the ASIC3 channel in an isoform-specific way.

Epigenetic control of cyp19a1a expression is critical for high temperature induced Nile tilapia masculinization.

In fish species with temperature-dependent sex determination (TSD) or genotypic sex determination plus temperature effects (GSD + TE), temperature can either affect sex differentiation or determine the sex. However, it is unknown if epigenetic control of cyp19a1a expression is critical for high temperature induced masculinization in the freshwater fish Nile tilapia. We analyzed the cyp19a1a DNA methylation levels in three age groups and found that they were lower in females than in males.

[Multi-dimensional Clinical Profile for Functional Gastrointestinal Disorders and Diagnostic and Therapeutic Approaches of Chinese Medicine].

Functional gastrointestinal disorders (FGIDs) are manifested as digestive symptoms, but relative symptoms cannot be confirmed by traditional inspection methods. In 2015 Rome Foundation put forward the conception of multi-dimensional clinical profile (MDCP) for FGIDs, which emphasized multi-dimensional assessment of disease state and aimed to develop individualized treatment program. Chinese medicine also has multi-dimensional thoughts in diagnosis and treatment and has much in com- mon with MDCP in refining diagnosis, attaching importance to psychological factors and spirits, seeking biomarkers, and so on.
