In this report, we present a case of duodenal squamous cell carcinoma with liver and adrenal metastasis. The patient was treated with gemcitabine and S-1, achieving a progression-free survival (PFS) of 7 months and an overall survival (OS) of 9 months.

α-Hederin induces human colorectal cancer cells apoptosis through disturbing protein homeostasis.

Protein homeostasis and quality control are crucial for normal cellular activities, and a severe imbalance in protein homeostasis can lead to cell death. α-Hederin, a pentacyclic triterpenoid saponin isolated from Fructus Akebia, has a clear role in promoting colorectal cancer (CRC) cell apoptosis and has been recently used for CRC therapy. However, whether the pro-apoptotic activity of α-hederin in CRC cells involves disturbing protein homeostasis remains unknown.

CRISPR-Cas9 gene editing strengthens cuproptosis/chemodynamic/ferroptosis synergistic cancer therapy.

Copper-based nanomaterials demonstrate promising potential in cancer therapy. Cu efficiently triggers a Fenton-like reaction and further consumes the high level of glutathione, initiating chemical dynamic therapy (CDT) and ferroptosis. Cuproptosis, a newly identified cell death modality that represents a great prospect in cancer therapy, is activated.

Clinical practice of acupuncture and moxibustion in treatment of tumor-related symptoms.

Tumor and its concomitant symptoms such as pain, fatigue and nausea bring a huge physical and mental burden to the patients. Although the medication is a common intervention for these symptoms, these problems have not been solved yet due to the side effects and patients' tolerance. In modern clinical practice of anti-tumor, acupuncture-moxibustion not only inhibits the growth of tumor, but also ameliorates the related symptoms as an auxiliary therapy.

Single-cell transcriptomics and Mendelian randomization reveal LUCAT1's role in right-sided colorectal cancer risk.

Colorectal cancer (CRC) is a malignancy with high incidence and mortality rates globally, categorized into left-sided and right-sided CRC, each exhibiting significant differences in molecular characteristics, clinical manifestations, and prognosis. This study employed single-cell transcriptomic data and various bioinformatics approaches, such as two-sample Mendelian randomization, reverse Mendelian randomization, colocalization analysis, directed filtering, pseudotime analysis, and intercellular communication analysis. It analyzed cellular-level disparities between left-sided and right-sided CRC, identifying distinct subpopulations with characteristic variations.

α-Hederin induces paraptosis by targeting GPCRs to activate Ca/MAPK signaling pathway in colorectal cancer.

Background: Non-apoptotic cell death is presently emerging as a potential direction to overcome the apoptosis resistance of cancer cells. In the current study, a natural plant agent α-hederin (α-hed) induces caspase-independent paraptotic modes of cell death.

Purpose: The present study is aimed to investigate the role of α-hed induces paraptosis and the associated mechanism of it.

Multiple-matrix metabolomics analysis for the distinct detection of colorectal cancer and adenoma.

Causal relationship of genetically predicted gut microbiota with thyroid cancer: a bidirectional two-sample mendelian randomization study.

Background: Previous investigations have demonstrated a correlation between the composition of gut microbiota and the development of thyroid cancer (TC). Nonetheless, there was no consensus on the causal effect of gut microbiota composition on TC risk. Therefore, the present study aimed to perform a bidirectional two-sample Mendelian randomization (MR) analysis to explore potential causal associations between gut microbiota and TC risk.

Efficacy and safety of Shenbai Granules for recurrent colorectal adenoma: A multicenter randomized controlled trial.

Background: Colorectal adenoma is benign glandular tumor of colon, the precursor of colorectal cancer. But no pharmaceutical medication is currently available to treat and prevent adenomas.

Purpose: To evaluate efficacy of Shenbai Granules, an herbal medicine formula, in reducing the recurrence of adenomas.

DPP2/7 is a Potential Predictor of Prognosis and Target in Immunotherapy in Colorectal Cancer: An Integrative Multi-omics Analysis.

Background: Colorectal cancer (CRC) ranks among the leading causes of cancerrelated deaths.

Objective: This study aimed to illuminate the relationship between DPP7 (also known as DPP2) and CRC through a combination of bioinformatics and experimental methodologies.

Methods: A multi-dimensional bioinformatic analysis on DPP7 was executed, covering its expression, survival implications, clinical associations, functional roles, immune interactions, and drug sensitivities.

Associations of nirmatrelvir-ritonavir treatment with death and clinical improvement in hospitalized patients with COVID-19 during the Omicron wave in Beijing, China: a multicentre, retrospective cohort study.

Background: The effectiveness of nirmatrelvir-ritonavir has mainly been shown in non-hospitalized patients with mild-to-moderate coronavirus disease 2019 (COVID-19). The real-world effectiveness of nirmatrelvir-ritonavir urgently needs to be determined using representative in-hospital patients with COVID-19 during the Omicron wave of the pandemic.

Methods: We performed a multicentre, retrospective study in five Chinese PLA General Hospital medical centers in Beijing, China.

Sophocarpine alleviates intestinal fibrosis via inhibition of inflammation and fibroblast into myofibroblast transition by targeting the Sirt1/p65 signaling axis.

In this study, we used alkaloids from Sophora flavescens to inhibit the SASP, leading to fibroblast-into-myofibroblast transition (FMT) to maintain intestinal mucosal homeostasis in vitro and in vivo. We used western blotting (WB) and immunofluorescence staining (IF) to assess whether five kinds of alkaloids inhibit the major inflammatory pathways and chose the most effective compound (sophocarpine; SPC) to ameliorate colorectal inflammation in a dextran sulfate sodium (DSS)-induced UC mouse model. IF, Immunohistochemistry staining (IHC), WB, disease activity index (DAI), and enzyme-linked immunosorbent assay (ELISA) were conducted to investigate the mechanism of action of this compound.

Association between the dietary inflammatory index and all-cause mortality in the U.S. cancer survivors: A prospective cohort study using the National Health and Nutrition Examination Survey database.

Membrane processes enhanced by various forms of physical energy: A systematic review on mechanisms, implementation, application and energy efficiency.

Membrane technologies in water and wastewater treatment have been eagerly pursued over the past decades, yet membrane fouling remains the major bottleneck to overcome. Membrane fouling control methods which couple membrane processes with online in situ application of external physical energy input (EPEI) are getting closer and closer to reality, thanks to recent advances in novel materials and energy deliverance methods. In this review, we summarized recent studies on membrane fouling control techniques that depend on (i) electric field, (ii) acoustic field, (iii) magnetic field, and (iv) photo-irradiation (mostly ultraviolet or visible light).

Single-cell analyses reveal cannabidiol rewires tumor microenvironment via inhibiting alternative activation of macrophage and synergizes with anti-PD-1 in colon cancer.

Colorectal tumors often create an immunosuppressive microenvironment that prevents them from responding to immunotherapy. Cannabidiol (CBD) is a non-psychoactive natural active ingredient from the cannabis plant that has various pharmacological effects, including neuroprotective, antiemetic, anti-inflammatory, and antineoplastic activities. This study aimed to elucidate the specific anticancer mechanism of CBD by single-cell RNA sequencing (scRNA-seq) and single-cell ATAC sequencing (scATAC-seq) technologies.
