Objective:To investigate the molecular mechanisms by which HMGB1 in lung cancer cells affects the function of lung cancer cells themselves and immune cells through the NF-κB pathway.Methods:Western blot detected HMGB1 expressions in Lewis lung cancer(LLC)cells,Raw264.7 cells,and mouse spleen cells,while tumor cell lysates(TCL)with low HMGB1 was pre-pared by inhibiting HMGB1 expression in lung cancer cells with glycyrrhetinic acid(GA);the effects of endogenous HMGB1 inhibi-tion or TCL with low HMGB1 on apoptosis and proliferation of lung cancer cells were detected by flow cytometry and CCK-8;TCL with normal HMGB1 or TCL with low HMGB1 was prepared by freeze-thawing;Raw264.7 cells and mouse splenocytes were treated with them for 48 h.Apoptosis and CD69 expression were detected by flow cytometry,and secretion of cytokines IL-2,IL-4,IL-6,TNF-α and TNF-β were detected by ELISA;Western blot detected lung cancer cells or immune cells.Western blot was performed to detect the protein expression of key signaling molecules of the NF-κB signaling pathway in lung cancer cells or immune cells.Results:HMGB1 was expressed in LLC cells,Raw264.7 cells,and mouse spleen cells,among which LLC cells had the highest expression of HMGB1,and 30 μg/ml GA had the best inhibitory effect on HMGB1 expression in LLC cells.Endogenous HMGB1 in LLC cells could promote cell proliferation.Exogenous HMGB1 in TCL induced apoptosis in lung cancer cells and inhibited immune cell activation and prolifera-tion.Inhibition of endogenous HMGB1 in lung cancer cells leaded to activation of the apoptosis-inducing factor CASP9 in the NF-κB signaling pathway,which was inhibited in lung cancer cells or immune cells after the action of TCL with low HMGB1.Conclusion:Tumor cell HMGB1 has a dual role in lung carcinogenesis,promoting the proliferation of lung cancer cells while suppressing the func-tion of immune cells,which in turn causes lung carcinogenesis,a process associated with the activation of the NF-κB signaling path-way in different cells.

Objective:This study retrospectively analyzed the clinical characteristics of patients newly diagnosed with acute myeloid leukemia (AML) who were admitted to the hematology intensive care unit (HCU) with critical illness. It also examined factors associated with critical illness and early mortality in these patients.Methods:Clinical data were collected from 91 newly diagnosed AML patients admitted to the HCU of the Department of Hematology, First Affiliated Hospital of Soochow University, from October 2020 to 2024. Reasons for HCU admission, major therapeutic interventions, and risk factors for critical illness and early mortality were analyzed.Results:The median time from diagnosis to HCU admission was 3 days ( IQR: 3–9 days), and the median HCU stay was 10 days ( IQR: 3–23 days). Of the 91 patients, 71 were admitted to the HCU before induction chemotherapy, while 20 were transferred to the HCU after its initiation. The leading causes of HCU admission were pulmonary infection (78.0% ), respiratory failure (44.0% ), hepatic insufficiency (28.6% ), renal insufficiency (27.5% ), disseminated intravascular coagulation (DIC; 25.3% ), and sepsis (23.1% ). Median Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and SOFA scores at HCU admission were 14 ( IQR: 11–18) and the median Sepsis Related Organ Failure Assessment (SOFA) score was 7 ( IQR: 4, 10). Major HCU interventions included vasoactive drugs, noninvasive and invasive mechanical ventilation, continuous renal replacement therapy, therapeutic leukocyte clearance, and cardiopulmonary resuscitation. Among patients receiving induction chemotherapy, the composite complete remission rate was 65.4%, and the overall remission rate was 88.5%. Thirty-five (38.5% ) patients died within 28 days of HCU admission. Independent risk factors for 28-day mortality were DIC ( OR=9.350, 95% CI 1.999–43.745, P=0.005), sepsis ( OR=6.817, 95% CI 1.571–29.582, P=0.010), and cardiac insufficiency ( OR=12.281, 95% CI 2.385–63.254, P=0.003) . Conclusion:The main reason for HCU admission in newly diagnosed critically ill AML patients was pulmonary infection. Nearly 40% of patients experisenced early death, and DIC, sepsis, and heart failure were factors influencing early mortatlity.

Objective:To evaluate the clinical efficacy of methylation sensitive-high resolution melting curve (MS-HRM) detection of IFN-induced protein 44-like (IFI44L) gene methylation in the diagnosis of systemic lupus erythematosus (SLE), as well as the relationship between IFI44L gene markers and the early onset of SLE.Methods:From February 2020 to September 2022, the MS-HRM was used to detect the methylation level of the IFI44L gene in peripheral blood mononuclear cells of 602 SLE patients and 524 other autoimmune disease patients (excluding SLE) from Beijing Peking Union Medical College Hospital, Guangdong Provincial People′s Hospital, and Shenzhen People′s Hospital, totaling 1 126 patients. Compared with the 2012 SLICC criteria, the suspected cases were followed up for 6 months until the onset and clinical diagnosis of SLE were confirmed. The measurement data of normal distribution were expressed as mean±SD, and the consistency analysis was performed using the Kappa consistency test. The clinical diagnostic efficacy indicators were calculated using the receiver operating characteristic (ROC) curve. Results:RR (95% CI) of early suspected cases was 17.06 (9.43, 30.82). The results of IFI44L gene methylation level were in good agreement with the 2012 SLICC criteria, and the sensitivity, specificity and total coincidence rate were 90.53%, 92.56% and 91.47%, respectively. The Kappa value (95% CI) was 0.829(0.796, 0.862) ( P<0.001). The diagnostic efficiency of IFI44L gene methylation level ( Kappa value 0.817) was superior to anti-nuclear antibody, anti-SM antibody and anti-dsDNA antibody ( Kappa value 0.418, 0.216 and 0.440, respectively). The Kappa values (95% CI) of methylation between MS-HRM and pyrosequencing was 0.861(0.806, 0.916), P<0.001. Conclusion:The hypomethylation of IFI44L gene methylation level detected by MS-HRM is closely related to the occurrence and development of SLE, and its diagnostic performance is better than that of three autoantibodies in SLE diagnosis, which can be used for the early diagnosis of SLE.
