Laparoscopic right hemicolectomy is a commonly utilized surgical procedure for the treatment of right-sided colon cancer. However, the high degree of difficulty in separating adjacent structures and the frequent vascular variations present in laparoscopic right hemicolectomy contribute to ongoing challenges, including unclear dissection planes, increased intraoperative bleeding, and insufficient lymph node clearance. This article proposes a combined approach that employs the surgical trunk as a guide, providing a clearer anatomical perspective and safer procedural steps.

Laparoscopic right hemicolectomy has emerged as the preferred surgical modality for managing right-sided colon cancer, offering minimally invasive benefits and expedited recovery. However, the right colon anatomy, characterized by complex vascular branching patterns and frequent variations, presents significant surgical challenges.

However, its application in glioblastoma (GBM) is hindered by the diminished capacity of CDT agents to traverse the blood-brain barrier (BBB), inadequate tumour targeting efficiency, and restricted availability of HO within the tumour microenvironment (TME). To address these challenges, we devised a novel CDT agent (Fe@tFNAs-ANG-3AT) based on a tetrahedral framework nucleic acids (tFNAs).

The antibacterial or tumor microenvironment (TME)-modulating approaches have been shown to markedly improve antitumor efficacy, strategies focused on normalizing the microbial environment are rarely reported. Here, we reported the development of an orally administered inulin-based hydrogel with colon-targeting and retention effects, containing hollow MnO nanocarrier loaded with the chemotherapeutic drug Oxa (Oxa@HMI).

We have previously demonstrated that the intranuclear miR-204-3p in macrophages protects against atherosclerosis, which shares multiple risk factors with metabolic dysfunction-associated steatotic liver disease (MASLD). Herein, we aimed to explore the functional significance of miR-204-3p in steatohepatitis.

The gut microbiota and Short-chain fatty acids (SCFAs) can influence the progression of diseases, yet the role of these factors on gastric cancer (GC) remains uncertain. In this work, the analysis of the gut microbiota composition and SCFA content in the blood and feces of both healthy individuals and GC patients indicated that significant reductions in the abundance of intestinal bacteria involved in SCFA production were observed in GC patients compared with the controls. ABX mice transplanted with fecal microbiota from GC patients developed more tumors during the induction of GC and had lower levels of butyric acid.

In the present study, a nanoplatform (Fe O @IR820@CpG)-based immunotherapy strategy that targets the multiple key steps in cancer-immunity cycle is developed: 1) promotes the release of tumor-derived proteins (TDPs), including tumor-associated antigens and pro-immunostimulatory factors), in addition to the direct killing effect, by photothermal (PTT) and photodynamic therapy (PDT); 2) captures the released TDPs and delivers them, together with CpG (a Toll-like receptor 9 agonist) to antigen-presenting cells (APCs) to promote antigen presentation and T cell activation; 3) enhances the tumor-killing ability of T cells by combining with anti-programmed death ligand 1 antibody (α-PD-L1), which collectively advances the outstanding of the anti-tumor effects on colorectal, liver and breast cancers. The broad-spectrum anti-tumor activity of Fe O @IR820@CpG with α-PD-L1 demonstrates that optimally manipulating anti-cancer immunity not singly but as a group provides promising clinical strategies.

No previous study has addressed gap junctions and miRNAs in sepsis because the internal mechanism of sepsis-induced intestinal injury is complex. Therefore, we studied the relationship between connexin43 (Cx43) and miR-181b and provided a research direction for further study of sepsis.

Background: Stemness acquirement is one of the hallmarks of cancer and the major reason for the chemoresistance and poor prognosis of colorectal cancer (CRC). Previous research has revealed the stimulatory role of paired related homeobox 1 (PRRX1) on CRC metastasis. However, the role of PRRX1 in stemness acquirement and chemoresistance of CRC is still not clear.

Transmembrane member 16A (TMEM16A), a component of hepatocyte Ca-activated chloride channel, has been implicated in a variety of liver diseases. However, its role in hepatic I/R injury remains unknown.

However, it is unknown how to accomplish these adjustments in CRC by actin cytoskeleton genes (ACGs) and here we investigated the role of hub prognosis-related ACGs-Diaphanous-related formin 3 (DIAPH3) in CRC, as a potential, novel target.
Methods: The ACGs gene set from the Kyoto Encyclopedia of Genes and Genomes (KEGG) was used to group CRC patients and select prognosis-related ACGs by univariate and multivariate Cox regression for constructing prognostic model.

Background: Opioids have been identified by the World Health Organization to be 'indispensable for the relief of pain and suffering'. Side-effects, such as nausea, vomiting, postoperative delirium, and effects on breathing, of opioids have been well investigated; however, the influence of opioids on monocyte-endothelial adherence has never been reported. Therefore, we explored the effects of representative opioids, fentanyl, sufentanil, and remifentanil, on monocyte-endothelial adherence and the underlying mechanisms.

Background: BMP3 gene is often found hypermethylated and hence inactivated in several types of cancers including colorectal cancer (CRC), indicating that it has a suppressor role in carcinogenesis. Though BMP3 is a reliable biomarker for screening CRC, the molecular mechanism of BMP3 in carcinogenesis remains largely unknown.
Methods: The expression level of BMP3 was examined by immunohistochemistry staining and western blot.
Intestinal injury has long been considered to play a crucial role in the pathophysiology of sepsis and has even been characterized as the "motor" of it. Thus, we explored the effects of connexin43 (Cx43) on sepsis-induced intestinal injury in order to provide potential therapeutic strategies. Rat cecal ligation and puncture (CLP) models and cell models (IEC-6 cells) pretreated with LPS were used in the current study.

Objective: To explore the expression of Rictor and mTOR in the colorectal cancer and their clinical significance.
Methods: The expression levels of Rictor and mTOR in HCT116, SW480, LoVo and HCoEpiC cells were detected by indirect immunofluorescence and Western blotting. Sixty-two paraffin-embedded surgical specimens of colorectal cancer tissue and adjacent tissues were examined for Rictor expression using immunohistochemistry.
The Wnt/β-catenin pathway is known to contribute to colorectal cancer (CRC) progression, although little is known about the contribution of β-catenin on this process. We investigated the role of miR-490-3p, which was recently reported to suppress tumorigenesis through its effect on Wnt/β-catenin signaling. We found that hypermethylation of the miR-490-3p promoter down-regulates miR-490-3p expression in CRC tissue.

The lack of depth perception and spatial orientation in two-dimensional image of traditional laparoscopy require long-term training of the surgeons. Three-dimensional (3D) laparoscopy provides stereoscopic visions as compared to monocular views in a traditional laparoscopic system. In this review, the authors summarize the clinical application of 3D laparoscopy and its current research progress.
