Neutrophil extracellular traps (NETs), intricate reticular structures released by activated neutrophils, play a pivotal regulatory role in the pathogenesis of malignant tumors. Lung cancer is one of the most prevalent malignancies globally, with persistently high incidence and mortality rates. Recent studies have revealed that NETs dynamically modulate the tumor microenvironment through unique pathological mechanisms, exhibiting complex immunoregulatory characteristics during the progression of lung cancer, and this discovery has increasingly become a focal point in tumor immunology research. This paper provides a comprehensive review of the latest advancements in NETs research related to lung cancer, offering an in-depth analysis of their impact on lung cancer progression, their potential diagnostic value, and the current state of research on targeting NETs for lung cancer prevention and treatment. The aim is to propose novel strategies to enhance therapeutic outcomes and improve the prognosis for lung cancer patients.

Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.

The isolated working heart of guinea pig perfused with Tyrode's solution could work normally for at least 60 min. It was shown that berbamine ( BA ) could depress the function of isolated working heart of guinea pig in dose-dependent manner. BA 3 mol/L could decrease the left ventricular pressure, aortic pressure, -dP/dtmax, aortic blood flow and coronary blood flow, and increase left ventricular end-diastolic pressure. BA 100 mol/L could result in the ventricular asystole, however, no obvious influence the contraction of atrium.It was also demonstrated that BA could antagonise the arrhythmias induced by the adrenaline in isolated working heart of guinea Pig.

AIM:To investigate the apoptotic pathway of MCF-7 breast cancer induced by the grub extract in vitro.METHODS:MTT assay was used to determine the effect of the grub extract on proliferation of MCF-7 human breast cancer cell line and cell toxicity.Morphological changes of the apoptosis in cancer cells were observed by HE staining through invert microscope,light microscope,AO/EB double fluorescent staining under fluorescent microscope.FCM was used to assay the change of apoptotic rate.The expression of Bcl-2,Fas,caspase-9,caspase-3 in apoptotic pathway was detected with immunocytochemical method before and after exposure to the grub extract,and the effect of that on apoptotic pathway was explored.RESULTS:(1)The MTT test showed that the growth of MCF-7 human breast cancer cell line was significantly inhibited by the grub extract in dose and time dependent manners.The inhibitory rate in exposure group was significantly different from that in control group(P
