Malignant pleural effusion(MPE)is a common complication in patients with advanced malignant tumors,which not only significantly reduces their quality of life but also shortens their survival duration.Despite the widespread use of traditional treatment methods such as thoracentesis and pleurodesis,their efficacy is limited accompanied by high recurrence rates.Therefore,exploring novel therapeutic strategies becomes particularly urgent.In recent years,immunotherapy has attracted extensive attention for its potential in cancer treatment.This article systematically reviews the roles of CD4+T cell subsets,including regulatory T cells(Treg),T helper cell(Th)17,Th9,and Th22 cells,within the immunosuppressive microenvironment of MPE.These cell subsets are involved in the formation of the immunosuppressive state of MPE through various mechanisms and play key roles in the occurrence and development of the disease.In addition,the article discusses in detail the role of immune checkpoint molecules,such as programmed death protein 1(PD-1),PD-1 ligand(PD-L1),and cytotoxic T-lymphocyte-associated protein 4(CTLA-4),in the immune evasion of MPE.The abnormal expressions of these molecules provide opportunity for tumor cells to evade immune system surveillance.At the same time,this article also summarizes the application prospects of novel immunotherapy strategies,such as adoptive cell therapy(ACT)and chimeric antigen receptor T cell(CAR-T)therapy,in the treatment of MPE.These innovative therapies offer possibilities for improving the prognosis of MPE patients through activating and enhancing the anti-tumor immune response.

Objective To investigate the effect of sanguinarine(SAN)on proliferation and ferroptosis of colorectal cancer cells.Methods SW620 and HCT-116 cells treated with different concentrations of SAN were examined for cell viability changes using CCK8 assay to determine the IC50 of SAN in the two cells.The inhibitory effects of SAN on proliferation,invasion and migration of the cells were evaluated using colony-forming assay and Transwell assays.ROS production in the treated cells was analyzed with flow cytometry,and lipid peroxide production was assessed by detecting malondialdehyde(MDA)level.Glutathione(GSH)levels in the cells were detected,and Western blotting was used to detect the expressions of ferroptosis-related proteins STUB1 and GPX4.Results SAN significantly inhibited the proliferation,invasion and migration of SW620 and HCT-116 cells.SAN treatment significantly promoted ROS production,increased intracellular MDA level,and lowered GSH level in the two cells(P<0.05).Western blotting showed that SAN significantly upregulated the expression of STUB1 and down-regulated the expression of its downstream protein GPX4(P<0.05).Conclusion SAN induces ferroptosis in colorectal cancer cells by regulating STUB1/GPX4,which may serve as a new therapeutic target for colorectal cancer.

Objective:To understand the cognition of the family caregivers of terminal cancer patients on digital health intervention, to clarify their actual needs, and to analyze the obstacles to their acceptance of digital health intervention, so as to develop a digital health intervention plan for the family caregivers of terminal cancer patients.Methods:From February 2024 to March 2024, the family caregivers of 16 patients with terminal cancer in Hunan Cancer Hospital Pain Hospice Ward were selected by objective sampling, who met the inclusion and exclusion criteria were interviewed in a semi-structured manner about the cognition and needs of digital health intervention, and the interview contents were sorted and analyzed using the Colaizzi7 step method.Results:A total of 16 family caregivers of terminal cancer patients, 4 males and 12 females, aged 26-55 years, were interviewed. Four themes were distilled from the interview results: family caregivers of terminally cancer patients agree on the importance of digital health interventions; lack of awareness of digital health interventions; expectations of digital health interventions; and possible confounders affecting digital health interventions.Conclusions:The family caregivers of terminal cancer patients had insufficient awareness of digital health intervention, but all showed affirmation of the development of digital health intervention services. It is recommended to actively improve the basic conditions of digital health services, strengthen publicity, raise the level of awareness of the family caregivers, and positively overcome the relevant interfering factors, so as to gradually promote the development of digital health services.

Objective To evaluate the effect of Internet-based psychosocial intervention for primary caregivers of patients with terminal stage cancer.Methods The relevant randomized controlled trials of Internet-based psychosocial intervention for primary caregivers of patients with terminal stage cancer were systematically searched from 10 databases,such as Chinese Biomedical Literature Database,CNKI,PubMed,Embase and CINAHL and etc.The search period was from the establishment to December 18,2023,and 2 investigators screened the literature according to inclusion and exclusion criteria and extracted data.Cochrane Manual 5.1.0 was used to assess the quality of the literature.Meta-analysis was performed using Revman 5.4 software.Results A total of 9 pieces of the literature including 592 primary caregivers were included.Meta-analysis showed that Internet-based psychosocial intervention reduced the level of anxiety and depression for primary caregivers of patients with terminal stage cancer[MD=-1.64,95％CI(-2.68,-0.59),P=0.002]and the burden of care[SMD=-0.39,95％CI(-0.60,-0.18),P＜0.001],and improved quality of life[SMD=0.25,95％CI(0.01,0.48),P=0.040];further research is needed to explore the effect of reducing the level of distress[MD=-0.88,95％CI(-1.91,0.16),P=0.100].Conclusion The Internet-based psychosocial intervention is effective in improving the anxiety,depression and the burden of care of the primary caregivers of patients with terminal stage cancer,and it can improve the quality of life;further research is needed to explore the level of distress reduction.

Substantial progress in the use of chemo-photodynamic nano-drug delivery systems (nano-DDS) for the treatment of the malignant breast cancer has been achieved. The inability to customize precise nanostructures, however, has limited the therapeutic efficacy of the prepared nano-DDS to date. Here, we report a structurally defined tandem-responsive chemo-photosensitive co-nanoassembly to eliminate primary breast tumor and prevent lung metastasis. This both-in-one co-nanoassembly is prepared by assembling a biocompatible photosensitive derivative (pheophorbide-diphenylalanine peptide, PPA-DA) with a hypoxia-activated camptothecin (CPT) prodrug [(4-nitrophenyl) formate camptothecin, N-CPT]. According to computational simulations, the co-assembly nanostructure is not the classical core-shell type, but consists of many small microphase regions. Upon exposure to a 660 nm laser, PPA-DA induce high levels of ROS production to effectively achieve the apoptosis of normoxic cancer cells. Subsequently, the hypoxia-activated N-CPT and CPT spatially penetrate deep into the hypoxic region of the tumor and suppress hypoxia-induced tumor metastasis. Benefiting from the rational design of the chemo-photodynamic both-in-one nano-DDS, these nanomedicines exhibit a promising potential in the inhibition of difficult-to-treat breast tumor metastasis in patients with breast cancer.
