Obesity usually exacerbates the immunosuppressive tumor microenvironment (ITME), hindering CD8⁺ T cell infiltration and function, which further represents a significant barrier to the efficacy of immunotherapy. Herein, a multifunctional liposomal system (CR-Lip) for encapsulating celastrol (CEL) was utilized to remodel obesity-related ITME and improve cancer immunotherapy, wherein Ginsenoside Rg3 (Rg3) was detected interspersed in the phospholipid bilayer and its glycosyl exposed on the surface of the liposome. CR-Lip had a relatively uniform size (116.5 nm), facilitating favorable tumor tissue accumulation through the interaction between Rg3 and glucose transporter 1 overexpressed in obese tumor cells. Upon reaching the tumor region, CR-Lip was found to induce the immunogenic cell death (ICD) of HFD tumor cells. Notably, the level of PHD3 in HFD tumor cells was effectively boosted by CR-Lip to effectively block metabolic reprogramming and increase the availability of major free fatty acids fuel sources. In vivo, experiments studies revealed that the easy-obtained nano platform stimulated enhanced the production of various cytokines in tumor tissues, DC maturation, CD8⁺ T-cell infiltration, and synergistic anticancer therapeutic potency with aPD-1 (tumor inhibition rate = 82.1%) towards obesity-related melanoma. Consequently, this study presented an efficacious approach to tumor immunotherapy in obese mice by encompassing tumor eradication, inducing ICD, and reprogramming metabolism. Furthermore, it offered a unique insight into a valuable attempt at the immunotherapy of obesity-associated related tumors.

Colorectal tumorigenesis generally progresses from adenoma to adenocarcinoma, accompanied by dynamic changes in the tumor microenvironment (TME). A randomized controlled trial has confirmed the efficacy and safety of Shen-Bai-Jie-Du decoction (SBJDD) in preventing colorectal tumorigenesis. However, the mechanism remains unclear. In this study, we employed single-cell RNA sequencing (scRNA-seq) to investigate the dynamic evolution of the TME and validated cell infiltration with multiplex immunohistochemistry and flow cytometry. Bulk RNA sequencing was utilized to assess the underlying mechanisms. Our results constructed the mutually verifiable single-cell transcriptomic atlases in Apc ^Min/+ mice and clinical patients. There was a marked accumulation of CCL22⁺ dendritic cells (DCs) and an enhanced immunosuppressive action, which SBJDD and berberine reversed. Combined treatment with cholesterol and lipopolysaccharide induced characteristic gene expression of CCL22⁺ DCs, which may represent "exhausted DCs". Intraperitoneal injection of these DCs after SBJDD treatment eliminated its therapeutic effects. TMEM131 derived CCL22⁺ DCs generation by TNF signaling pathway and may be a potential target of berberine in retarding colorectal tumorigenesis. These findings emphasize the role of exhausted DCs and the regulatory mechanisms of SBJDD and berberine in colorectal cancer (CRC), suggesting that the multi-component properties of SBJDD may help restore TME homeostasis and offer novel cancer therapy.

Objective To investigate the effect of circRNA-homeodomain-interacting protein kinase 2(circHIPK2)on angiotensinⅡ(AngⅡ)-induced apoptosis of vascular endothelial cells through the regulation of the miR-7-5p/transcription factor 4(TCF4)axis.Methods Human umbilical vein endothelial cells(HUVECs)were randomly divided into the control,model,negative control cotrans-fection,circHIPK2 knockdown,miR-7-5p overexpression,and circHIPK2 knockdown+miR-7-5p knockdown groups.Except for the control group,all other groups were administered 10 nmol/L Ang Ⅱ to establish a hypertensive injury model.The circHIPK2,miR-7-5p,and TCF4 mRNA expression levels were detected after transfection.Apoptosis,proliferation,mitochondrial membrane potential,reactive oxygen species(ROS),antioxidant enzymes,pro-inflammatory factors,and TCF4 protein expression were assessed.Results Compared with the control group,the expressions of circHIPK2 and TCF4 mRNA,cell apoptosis rate,relative expression of ROS,levels of IL-6,IL-1β,and IL-18,and expressions of Bax and TCF4 protein increased,and cell viability,miR-7-5p mRNA expression,mitochondrial mem-brane potential,activities of superoxide dismutase(SOD)and catalase(CAT),and Bcl-2 protein expression decreased in the model group(P＜0.05).Both circHIPK2 knockdown and miR-7-5p overexpression reversed Ang Ⅱ-induced pathological changes in vascular endothelial cells.miR-7-5p knockdown reduced the effect of circHIPK2 knockdown on pathological cellular changes in the model group.Conclusion circHIPK2 knockdown can weaken TCF4 expression by upregulating miR-7-5p,thereby reducing Ang Ⅱ-induced inflam-mation and oxidative stress in vascular endothelial cells and ultimately inhibiting cell apoptosis.

A retrospective analysis was conducted on data of 13 patients with rectal or anal canal lesions involving the dentate line who underwent endoscopic submucosal dissection (ESD) at the Digestive Endoscopy Center of Jiangsu Province Hospital of Chinese Medicine from January 2022 to July 2023. The efficacy and safety of ESD were evaluated. ESD was performed on 14 lesions in 13 patients. The lesions had a length of 1.4 to 12.5 cm and 5.4 cm in average, which were removed entirely in a single session, with an R0 resection rate of 92.31% (12/13). The ESD procedure duration ranged from 35 to 225 minutes, with an average of 88.3 minutes. Anal canal stenosis occurred in 1 case after ESD, which was improved after treatment with anal dilatation. No delayed bleeding, perforation, or other complications occurred. Pathological examination after ESD revealed 6 tubulovillous adenoma, 2 tubular adenoma, 3 tubular adenocarcinoma, and 2 squamous epithelial intraepithelial neoplasia (both 2 lesions were combined with human papillomavirus infection). In one case of tubular adenocarcinoma, the local resection margin showed focal tubulovillous adenoma, while the other cases were negative on lateral margins around and basal margins. The median follow-up period was 7.0 months (range 2 to 13 months), with no local residue, recurrence or metastasis observed. ESD is safe and effective for early rectal or anal canal lesions involving the dentate line, and is worthy of clinical promotion and application.
