Cancer is one of the most lethal and burdensome diseases worldwide. Its progression not only causes irreversible damage to the body, but also imposes a substantial psychological burden on patients due to its complex prognosis. Immune imbalance, a hallmark of the tumor microenvironment (TME), accelerates tumor invasion and metastasis by impairing the function of effector immune cells, promoting the abnormal infiltration of immunosuppressive cells, and disrupting cytokine homeostasis, thereby constituting a major barrier to the efficacy of cancer immunotherapy. Compared with conventional chemotherapy and radiotherapy, aerobic exercise has shown considerable potential in antagonizing tumor progression through relatively mild but effective immunomodulatory mechanisms. On the one hand, regular aerobic exercise enhances the number and activity of key effector immune cells, such as CD8⁺ T cells, thereby strengthening their ability to recognize and eliminate tumor cells and alleviate immune imbalance. On the other hand, aerobic exercise promotes tumor vascular normalization, improves vascular maturity, and stimulates the secretion of irisin and other anti-inflammatory myokines, thereby remodeling the TME and relieving its immunosuppressive state to delay tumor progression. However, psychological stress following a cancer diagnosis can not only act as an independent disruptive factor that exacerbates immune imbalance within the TME, but also amplify the effects of other detrimental factors, such as reduced treatment adherence, thereby further weakening the antagonistic effect of aerobic exercise on tumor growth. Psychological stress, as a chronic stressor, promotes the excessive secretion of emotion-related hormones, including glucocorticoids (GCs) and norepinephrine (NE), which further suppress the activation and effector functions of antitumor immune cells such as CD8⁺ T cells and natural killer (NK) cells, while facilitating the recruitment of protumor immune cells such as regulatory T cells (Tregs). These changes ultimately disrupt immune homeostasis in the TME, promote tumor immune evasion, accelerate tumor invasion and metastasis, and offset the beneficial effects of aerobic exercise on tumor control. In addition, psychological stress induces hyperactivation of the hypothalamic-pituitary-adrenal (HPA) axis and abnormal excitation of the sympathetic nervous system (SNS), thereby maintaining elevated levels of GCs, NE, and related stress hormones, suppressing inflammatory chemokine expression and immune cell recruitment, and further disturbing immune homeostasis in the TME, which accelerates tumor progression. More importantly, prolonged psychological stress can also disrupt the homeostasis of central neurotransmitters, such as 5-hydroxytryptamine (5-HT) and glutamate (Glu). This not only directly inhibits the activation and effector functions of antitumor immune cells and promotes the establishment of an immunosuppressive microenvironment, but also impairs cellular energy metabolism and continuously provides energy for tumor cells through metabolic reprogramming, thereby sustaining rapid tumor growth and adaptation to a hostile TME. Ultimately, these alterations contribute to the dysregulation of “neuro-endocrine-immune” axis and weaken the protective effect of aerobic exercise against tumor progression. Therefore, this review focuses on the interaction between psychological stress and the “neuro-endocrine-immune” axis, with particular emphasis on the mechanisms by which psychological stress induces immune imbalance and weakens the antagonistic effect of aerobic exercise on tumor progression. We further highlight the important role of psychological stress in tumor progression and propose that combining psychotropic interventions, aerobic exercise, and clinical antitumor immunotherapy may help restore the tumor-killing capacity of the immune system. Such a multimodal strategy may exert synergistic effects at multiple levels, including psychological stress relief, neuroendocrine regulation, and reconstruction of immune homeostasis, thereby providing new perspectives for identifying therapeutic targets in solid tumors, enhancing the efficacy of cancer immunotherapy, and improving patient prognosis.

Objective To investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

Objective To establish a flow cytometry method for detecting C1s protein on platelet surface and preliminarily explore its potential application value in the auxiliary diagnosis of primary immune thrombocytopenia(ITP).Methods C1s-conjugated 2 μm car-boxylated magnetic beads(C1s beads)were prepared and used as quality control particles.Fluorescein isothiocyanate(FITC)-labeled anti-C1s antibody was employed as the detection antibody to develop a flow cytometric assay for detecting C1s protein expression on platelets.The intra-assay and inter-assay precision,as well as the dilution linearity of the method,were evaluated.Subsequently,the expression levels of C1 s protein on the surface of platelets were compared among the ITP group,the non-ITP thrombocytopenia group,and the healthy control group.Results Light microscopy showed that both unconjugated carboxylated magnetic beads(blank beads)and C1s-conjugated beads were uniformly dispersed without aggregation.Under fluorescence microscopy,C1s beads exhibited strong yellow-green fluorescence,whereas the blank beads showed no fluorescence signal.The established flow cytometry assay exhibited ac-ceptable precision,with intra-assay coefficient of variation(CV)values of 7.02％,7.12％,and 3.91％for low,medium,and high con-centrations of C1s beads,respectively,and inter-assay CV values of 13.49％,6.15％,and 0.78％,respectively.The dilution linearity was satisfactory,coefficient of determination(R2)=0.998 8.Clinical sample testing revealed that the proportion of C1s-positive plate-lets in ITP group(2.56±0.79)％was significantly higher than that in healthy control group(0.23±0.18)％and the non-ITP thrombo-cytopenia control group(0.22±0.10)％,with statistically significant differences(both P＜0.05).Conclusion This study successfully established a stable and reliable flow-cytometry method for quantifying C1s expression on platelet surface and preliminarily demonstrated that C1s expression is significantly elevated on platelets of ITP patients,suggesting that C1s could serve as a potential auxiliary diag-nostic marker for ITP.

Fibroblast growth factor,as a critical protein regulating cell growth and differentiation,exhibits aberrant signaling closely associated with various pathological pathologies,including cancer.Among the members of the fibroblast growth factor family,fibroblast growth factor 9(FGF9)has been identified as a critical player in cancer initiation and progression.While numerous studies have investigated the molecular mechanisms of FGF9 individually,comprehensive reviews addressing its impact in cancer remain scarce.This article systematically reviews the functional mechanisms and regulatory networks of FGF9 in cancer,with a focus on its roles in common malignancies such as lung cancer,liver cancer,gastric cancer,colorectal cancer,breast cancer,and ovarian cancer.The aim is to facilitate translational research on FGF9 for targeted cancer diagnosis and therapy.
