SQYC formula improves the efficacy of PD-1 monoclonal antibodies in MSS colorectal cancer by regulating dendritic cell mitophagy via the PINK1-Parkin pathway.

Background: Microsatellite stable (MSS) colorectal carcinomas (CRCs) exhibit poor responsiveness to immunotherapy such as immune checkpoint inhibitors (ICIs). In the realm of clinical cancer treatment, traditional Chinese medicines (TCMs) are extensively utilized for their immunomodulatory properties. Shen Qi Yi Chang (SQYC), a clinical prescription for CRC treatment, improve the life quality of CRC patients and enhance their immune function.

Resiliency process in the family after childhood leukaemia diagnosis: A longitudinal qualitative study.

Aims: To construct a conceptual framework on the process of family resilience during the first year following childhood leukaemia diagnosis.

Design: A longitudinal qualitative interview study.

Methods: A longitudinal qualitative study following a grounded theory methodology was employed.

Self-Assembled Amphiphilic Chitosan Nanomicelles: Synthesis, Characterization and Antibacterial Activity.

Although amphiphilic chitosan has been widely studied as a drug carrier for drug delivery, fewer studies have been conducted on the antimicrobial activity of amphiphilic chitosan. In this study, we successfully synthesized deoxycholic acid-modified chitosan (CS-DA) by grafting deoxycholic acid (DA) onto chitosan C-NH, followed by grafting succinic anhydride, to prepare a novel amphiphilic chitosan (CS-DA-SA). The substitution degree was 23.

Development and validation of a machine learning model to predict venous thromboembolism among hospitalized cancer patients.

Objective: Hospitalized cancer patients are at high risk of venous thromboembolism (VTE). However, no predictive model has been specifically developed for this population. Machine learning (ML) is advantageous for model development.

Metabolomics Tools Assisting Classic Screening Methods in Discovering New Antibiotics from Mangrove Actinomycetia in Leizhou Peninsula.

Mangrove actinomycetia are considered one of the promising sources for discovering novel biologically active compounds. Traditional bioactivity- and/or taxonomy-based methods are inefficient and usually result in the re-discovery of known metabolites. Thus, improving selection efficiency among strain candidates is of interest especially in the early stage of the antibiotic discovery program.

Identification of a new TRAF6 inhibitor for the treatment of hepatocellular carcinoma.

Tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6) is an E3 ubiquitin ligase that plays a crucial role in signal transduction. Previous studies have demonstrated that TRAF6 is overexpressed in hepatocellular carcinoma (HCC) and that TRAF6 knockdown dramatically attenuates tumor cell growth. Thus, TRAF6 may represent a potential therapeutic target for the treatment of HCC.

Imaging genomics for accurate diagnosis and treatment of tumors: A cutting edge overview.

Imaging genomics refers to the establishment of the connection between invasive gene expression features and non-invasive imaging features. Tumor imaging genomics can not only understand the macroscopic phenotype of tumor, but also can deeply analyze the cellular and molecular characteristics of tumor tissue. In recent years, tumor imaging genomics has been a key in the field of medicine.

Gut microbiota metabolites as integral mediators in cardiovascular diseases (Review).

Cardiovascular diseases (CVDs), such as atherosclerosis, hypertension, myocardial infarction and diabetic heart disease, are associated with high morbidity and mortality rates worldwide, and may also induce multiple organ failure in their later stages, greatly reducing the long‑term survival of the patients. There are several causes of CVDs, but after nearly a decade of investigation, researchers have found that CVDs are usually accompanied by an imbalance of gut microbiota and a decreased abundance of flora. More importantly, the metabolites produced by intestinal flora, such as trimethylamine and trimethylamine N‑oxide, bile acids, short‑chain fatty acids and aromatic amino acids, exert different effects on the occurrence and development of CVDs, as observed in the relevant pathways in the cells, which may either promote or protect against CVD occurrence.

Endoplasmic reticulum stress, hepatocyte CD1d and NKT cell abnormalities in murine fatty livers.

The liver regulates lipid homeostasis and is enriched with natural killer T (NKT) cells that respond to lipid antigens. Optimal maturation and activation of NKT cells requires their interaction with lipid antigens that are presented by cluster of differentiation-1 (CD-1) molecules on antigen-presenting cells. Hepatocytes express CD1d and present lipid antigens to NKT cells.

Sustained activation of Rac1 in hepatic stellate cells promotes liver injury and fibrosis in mice.

Rac, a small, GTP-binding protein in the Rho family, regulates several cellular functions, including the activation of NADPH oxidase, a major intracellular producer of reactive oxygen species (ROS). Hepatic stellate cells (HSCs) isolated from mice that are genetically deficient in NADPH oxidase produce less ROS, and their activation during chronic liver injury is abrogated, resulting in decreased liver fibrosis. Therefore, we hypothesized that HSC ROS production and activation would be enhanced, and fibrosis worsened, by increasing Rac expression in HSCs.

Interleukin-15 increases hepatic regenerative activity.

Background/aims: Interleukin-15 (IL-15) is expressed in many organs. It generally inhibits apoptosis and increases cellular proliferation and differentiation. However, IL-15's roles in liver are unknown.

Role for hedgehog signaling in hepatic stellate cell activation and viability.

Hepatic stellate cells (HSC) have a complex phenotype that includes both neural and myofibroblastic features. The Hedgehog (Hh) pathway has been shown to direct the fate of neural and myofibroblastic cells during embryogenesis and during tissue remodeling in adults. Therefore, we hypothesized that Hh signaling may regulate the fate of HSC in adults.

Occupational health services in "small plants" in Shanghai County.

With the reorganization of the grassroots structure and economic readjustment, the commune- and brigade-run plants have now been changed to district (town)- and village-run plants, respectively, and the role of industrial production has become more important to the total income of the people. The Qi-yi Commune (District) is a good example. The number of plants showed an increase of 80% from 1975 to 1983, whereas the number of workers increased by 149%.
