Deficiency of neuronal LGR4 increases energy expenditure and inhibits food intake via hypothalamic leptin signaling.

The metabolic effects of leucine-rich repeat-containing G protein-coupled receptor 4 (LGR4) remain largely unknown. Here, we showed that knockdown of Lgr4 in nestin progenitor or Sp1 mature neurons reduced high fat diet (HFD)-induced obesity by increasing energy expenditure and inhibiting food intake. Deficiency of LGR4 in AgRP neurons increased energy expenditure, and inhibited food intake, leading to alterations in glucose and lipid metabolism.

Mineralocorticoid Receptor Antagonism Reduces Atrial Arrhythmias Post-Cardiac Surgery and Attenuates Atrial Stress Responses to Cardioplegic Arrest.

Background: New postoperative atrial fibrillation (POAF) occurs in about 40% after cardiac surgery. Mineralocorticoid receptor antagonists (MRA) are known to reduce chronic atrial fibrillation (AF) development and burden. We examined the impact of preoperative MRA use on POAF and also examine the atrial cell type impacted by MRA treatment during cold cardiac preservation.

Methods: This was retrospective study. Eighty patients with ACI admitted to Institute of Psychology, Chinese Academy of Sciences from January 2021 to September 2022 were included and randomly divided into observation group (n=40) and control group(n=40).

Enhancing Iodine Capture of Porous Organic Cages through N-Heteroatom Engineering.

Iodine radioisotopes, produced or released during nuclear-related activities, severely affect human health and the environment. The efficient removal of radioiodine from both aqueous and vapor phases is crucial for the sustainable development of nuclear energy. In this study, we propose an "N-heteroatom engineering" strategy to design three porous organic cages with N-containing functional groups for efficient iodine capture.

Nuclear Acly protects the liver from ischemia-reperfusion injury.

Background And Aims: Hepatic ischemia-reperfusion (IR) injury is the most common complication that occurs in liver surgery and hemorrhagic shock. ATP citrate lyase (Acly) plays a pivotal role in chromatin modification via generating acetyl-CoA for histone acetylation to influence biological processes. We aim to examine the roles of Acly, which is highly expressed in hepatocytes, in liver IR injury.

The Functions and Mechanisms of Long Non-coding RNA SNHGs in Gastric Cancer.

Gastric cancer (GC) is one of the most common malignancies worldwide. Despite significant advancements in surgical and adjuvant treatments, patient prognosis remains unsatisfactory. Long non-coding RNAs (lncRNAs) are a class of RNA molecules that lack protein-coding capacity but can engage in the malignant biological behaviors of tumors through various mechanisms.

Oxygen-limited pyrolysis and incineration impact on biochar transport.

At present, studies on biochar transport have focused on biochar obtained by oxygen-limited pyrolysis, which may differ from conventional biochar produced by incineration in nature. This work investigated the transport and retention mechanisms of three types of oxygen-limited pyrolytic biochar and three types of traditional biochar in saturated porous media. The results showed that the specific surface area of the three oxygen-limited pyrolysis biochar (180-200 m·g) was higher than that of the traditional biochar (50-60 m·g).

Inhibition of AGEs-RAGE-PP2A Axis Alleviates Cognitive Impairment after Chronic Heart Failure.

To investigate the effect of the AGEs-RAGE-PP2A axis on cognitive impairment (CI) after chronic heart failure (CHF). Mice were divided into six groups: Sham, TAC, Sham+RAGE-/-, TAC+RAGE-/-, AG, and FTY720 group. AG mice and FTY720 mice were treated with AGEs inhibitor (aminoguanidine, AG) and PP2A activator (FTY720) respectively after TAC surgery.

Genome mosaic structure of two novel HIV-1 recombinant forms (CRF01_AE/B) in men who have sex with men in Hebei, China.

Background: Homosexual contact is the main route of human immunodeficiency virus type one (HIV-1) transmission in Cangzhou Prefecture, Hebei, China. Moreover, the number of circulating recombinant forms (CRFs) and unique recombinant forms (URFs) in this key population is ever increasing.

Methods: In this study, we identified two novel URFs (hcz0017 and hcz0045) from two men who have sex with men (MSM) based in Cangzhou Prefecture.

Carcinoma with signet ring cell differentiation associated with invasive breast cancer: A case report.

Carcinoma with signet ring cell differentiation is uncommon in patients with invasive breast cancer. Clinical evidence has suggested that the prognosis of this tumor is usually poor if the stage is advanced. The case of a 40-year-old female patient with primary cancer in the right breast accompanied by bilateral neck, axillary, right subclavian and mediastinal lymph node metastases, and left breast metastasis is presented in the current study.

Biclonal lymphoplasmacytic lymphoma/Waldenström macroglobulinemia associated with POEMS syndrome: A case report and literature review.

Due to its unique clinical, immunological and molecular genetic characteristics, biclonal lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM) with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes (POEMS) syndrome is extremely rare in clinical practice, and there is no standard treatment for patients afflicted with this condition. In the present case report, a rare case of double LPL/WM with POEMS syndrome is described. The patient, a 65-year-old male, exhibited significant renal impairment and polylymphadenopathy.

Chinese expert consensus on the diagnosis and treatment of HER2-altered non-small cell lung cancer.

Human epidermal growth factor receptor 2 (HER2) possesses tyrosine kinase activity and participates in cell growth, differentiation and migration, and survival. Its alterations, mainly including mutations, amplifications, and overexpression are associated with poor prognosis and are one of the major drivers in non-small cell lung cancer (NSCLC). Several clinical trials had been investigating on the treatments of HER2-altered NSCLC, including conventional chemotherapy, programmed death 1 (PD-1) inhibitors, tyrosine kinase inhibitors (TKIs) and antibody-drug conjugates (ADCs), however, the results were either disappointing or encouraging, but inconsistent.

A prognostic nomogram for predicting overall survival in colorectal mucinous adenocarcinoma patients based on the SEER database.

A nomogram was constructed to predict the survival of patients with colorectal mucinous adenocarcinoma based on data extracted from the Surveillance, Epidemiology and End Result (SEER) database. Data collected between 2010 and 2018 were obtained from the SEER database. The log-rank test and multivariate Cox regression were performed to identify the independent prognostic factors for overall survival, which were further used to construct a nomogram model to predict 1-, 3-, and 5-year overall survival.

Chinese expert consensus on the multidisciplinary management of pneumonitis associated with immune checkpoint inhibitor.

Immune checkpoint inhibitors (ICIs) have successfully treated a number of different types of cancer, which is of great significance for cancer treatment. With the widespread use of ICIs in clinical practice, the increasing checkpoint inhibitor pneumonia (CIP) will be a challenge to clinicians. To guide the diagnosis and treatment of CIP, we conducted in-depth discussions based on the latest evidence, forming a consensus among Chinese experts on the multidisciplinary management of CIP.

BC loaded with nano-FeS for the catalytic degradation of QNC: Contribution and mechanism of OFGs for reductive iron regeneration.

Biochar currently served as the support for dispersed metal nanoparticles and cooperated with pyrite to generate more reactive radicals in organic pollution degradation system. But the mechanism of interaction between biochar and pyrite has not been elucidated. In this paper, biochar with oxygen-containing functional groups (OFGs) served as a stable dispersant to prepare nano-FeS loaded biochar materials (BC@nano-FeS).

Efficacy and safety of triplet chemotherapy plus anti-EGFR agents in metastatic colorectal cancer: a systematic review and meta-analysis.

Background: To date, the optimal treatment for potentially resectable metastatic colorectal cancer (mCRC) patients has yet to be determined. Encouraging results have been reported in studies exploring the efficacy of triplet chemotherapy plus anti-epidermal growth factor receptor (anti-EGFR) target agents. Thus, we conducted a meta-analysis to evaluate the efficacy and safety of triplet chemotherapy plus anti-EGFR target agents.
