Lung cancer remains one of the leading causes of cancer-related morbidity and mortality worldwide, and its treatment continues to face major challenges such as therapeutic resistance and tumor recurrence. Pyroptosis, a newly characterized form of programmed cell death, induces tumor cell death through gasdermin-mediated membrane pore formation and is accompanied by the release of inflammatory mediators, thereby playing complex roles in lung cancer initiation, progression, and modulation of the tumor microenvironment. Active components and herbal formulas derived from traditional Chinese medicine can modulate pyroptosis-related signaling pathways through multi-target mechanisms, showing potential advantages in inducing lung cancer cell death, inhibiting proliferation and migration, and reversing chemoresistance. This review systematically summarizes relevant studies from domestic and international sources, focusing on the molecular mechanisms of pyroptosis, its roles in lung cancer development and tumor microenvironment remodeling, and the current research progress on traditional Chinese medicine-based interventions targeting pyroptosis, with the aim of providing references for the prevention and treatment of lung cancer using traditional Chinese medicine.

AIM: To compare the clinical outcomes of extended depth-of-focus intraocular lenses(EDOF IOLs)using either micromonovision implantation or mixed implantation of EDOF and diffractive bifocal IOLs.METHODS: This retrospective clinical trial included 130 patients(260 eyes), who were divided into two groups. Group RR comprised 70 patients(140 eyes)bilaterally implanted with ZXR00 IOLs(Tecnis ZXR00, where one target was -0.5 D to -0.75 D and the other was 0 to -0.25 D). Group RM comprised 60 patients(120 eyes)unilaterally implanted with both ZXR00 and ZMB00 IOLs(Tecnis ZMB00, 0 to -0.25 D). Postoperative outcomes were compared after 3 mo, including visual acuity, defocus curves, stereoacuity, modulation transfer functions(MTFs), higher-order aberrations, and Visual Function-14(VF-14)questionnaire responses.RESULTS: Group RR had superior bilateral intermediate vision, while the group RM had superior bilateral near vision(both P<0.05). Group RM also exhibited superior MTFs and reduced higher-order aberrations(both P<0.05). Stereoacuity and VF-14 questionnaire results showed no statistically significant difference between groups(P>0.05).CONCLUSION: The implantation of micromonovision has significantly improved near vision. IOLs and their collocation can be customized according to individual patient needs to achieve precise treatment and provide cataract patients with high-quality vision.

The concept of holism is the core idea of traditional Chinese medicine (TCM). Various organs and tissues coordinate with each other to maintain the body's life activities, with a close and mutual influence between the spleen, stomach, and the central nervous system (brain). The gut-brain axis plays an important bridging role between the digestive system and the central nervous system, achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence, coordination, and integration between different organs and systems; multimodality, on the other hand, utilizes multiple sensory modalities, such as vision, hearing, and touch, to convey information. By combining TCM theory with the gut-brain axis theory, a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders, precancerous gastrointestinal diseases, Alzheimer's disease, Parkinson's syndrome, type 2 diabetes, and depression.

To investigate body composition and associated factors in adolescents undergoing long-term regular sports training. This prospective longitudinal cohort study employed convenience sampling to recruit adolescents receiving structured athletic training at Jining Sports Training Center in June 2023. Baseline measurements included height, weight, body mass index (BMI), blood pressure, heart rate, waist circumference, and hip circumference. Questionnaires assessed sleep duration, screen time, and household income. Follow-up measurements in June 2024 repeated these assessments while adding bioelectrical impedance analysis for body composition (lean mass, skeletal muscle mass, fat mass, and body fat percentage). Linear regression models examined associations between training type (direct-contact vs. non-contact sports) and follow-up body fat percentage, BMI, and waist circumference as dependent variables, adjusting for covariates. The study included 110 adolescents (39 female, 71 male) with median age 13.21 years (IQR: 12.46-14.33). Participants comprised 65 direct-contact and 45 non-contact athletes. Baseline prevalence rates were 27.27% for overweight/obesity, 24.55% for elevated waist circumference, and 16.36% for elevated blood pressure. At follow-up, corresponding rates were 24.55%, 26.36%, and 13.64% respectively. The elevated blood pressure subgroup showed significantly higher waist circumference ( Despite regular athletic training, substantial proportions of adolescents exhibited overweight/obesity, abdominal obesity, and elevated blood pressure, warranting clinical attention. Training modality appears to influence body composition changes, with direct-contact sports associated with more favorable adiposity-related outcomes.

Objective:To investigate the treatment and prognosis of esophageal cancer patients with pulmonary resection history.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 58 esophageal cancer patients with pulmonary resection history who were admitted to Chest Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Jiangxi Provincial People's Hospital from May 2019 to April 2024 were collected. There were 52 males and 6 females, aged (69±3)years. Observation indicators: (1) surgical and postopera-tive conditions; (2) postoperative pathological examination results; (3) follow-up; (4) stratified analysis. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was conducted using the non-parametric rank sum test. The Kaplan-Meier method was used to plot survival curve and calculate survival rate, and the Log-rank test was used for survival analysis. Results:(1) Surgical and postoperative conditions. Of the 58 esophageal cancer patients, 49 patients underwent transthoracic approach (26 cases of ipsilateral approach and 23 cases of contralateral approach of pulmonary resection history), and 9 patients underwent mediastinoscopic-laparoscopic approach. There were 57 cases with R 0 resection and 1 case with R 2 resection because of tumor invading carina. The total operation time of 58 patients was (246±27)minutes, and the volume of intraoperative blood loss was (114±29)mL. There was no unplanned reoperation or perioperative death for all patients. The duration of postoperative hospital stay of 58 patients was (10.4±4.6)days, and time for intensive care unit stay was (1.4±0.5)days, and no patient readmitted to intensive care unit due to changes in conditions. The postoperative total incidence of complications of 58 patients was 41.4%(24/58). The Clavien-Dindo grading of complications for all patients was 1-2 grade. (2) Postoperative pathological examination results. Results of postoperative pathological examination showed there were 51 cases of squamous cell carcinoma, 6 cases of adenocarcinoma, and 1 case of melanoma. Number of lymph node dissected of 58 patients was 27±6. The ratio of patient with positive lymph node was 37.9%(22/58). One patient may experience more than 1 region of positive lymph node metastasis. Results of postoperative pathological staging showed 5 cases of ⅠA stage, 2 cases of ⅠB stage, 13 cases of ⅡA stage, 15 cases of ⅡB stage, 4 cases of ⅢA stage, 16 cases of ⅢB stage, and 3 cases of ⅣA stage. Thirteen of the 58 patients underwent neoadjuvant therapy, with the pathological staging as 6 cases of Ⅰ stage, 4 cases of Ⅱ stage, 3 cases of ⅢB stage after therapy. Results of postoperative tumor regression grade for the 13 patients with neoadjuvant therapy showed 4 cases of grad 0, 3 cases of grade 1, 6 cases of grade 2. (3) Follow-up. All 58 patients were followed for 24 (4, 50)months, and no patient died within 90 days after surgery. During the follow-up period, 19 patients experienced tumor recurrence and metastasis and 17 patients died. Twenty-one patients underwent postoperative adjuvant therapy, including 7 cases with chemoradiotherapy, 7 cases with chemotherapy, 3 cases with chemotherapy and immunotherapy, 2 cases with immuno-therapy, 2 cases with radiotherapy. The postoperative 1-, 2-year overall survival rates of the 58 patients were 91.3%, 78.7%, respectively, of whom undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery with postoperative 1-, 2-year overall survival rates as 89.2%, 83.1% and 85.7%, 53.6%, respectively. The postoperative 1-, 2-year esophageal cancer specific survival rates for patients undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery were 94.4%, 87.9% and 85.7%, 71.4%, respectively. There was no significant difference in postoperative 1-, 2-year overall survival rates and postoperative 1-, 2-year esophageal cancer specific survival rates between patients undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery ( P>0.05). (4) Stratified analysis. Of the 49 patients underwent transthoracic approach for esophageal cancer, there were significant differences in surgical method, surgical type, time of chest surgery, cases with upper mediastinal lymph node dissection, and duration of postoperative hospital stay between patients with pulmonary resection history as ipsilateral approach and contralateral approach ( χ2=11.74, 11.68, t=-2.25, χ2=8.45, t=-2.17, P<0.05), and there was no significant difference in total operation time, volume of intraoperative blood loss, the number of lymph node dissected, post-operative total complications, and postoperative pathological TNM staging ( P>0.05). For patients with pulmonary resection history as ipsilateral approach and contralateral approach, the postopera-tive 1-, 2-year esophageal cancer specific survival rates were 95.5%, 95.5% and 81.4%, 71.1%, showing a significant difference between them ( χ2=5.63, P<0.05). Conclusions:The transthoracic approach and mediastinoscopic-laparoscopic approach are safe and feasible for esophageal cancer patients with pulmonary resection history. Compared with patients with pulmonary resection history as contralateral approach, patients with pulmonary resection history as ipsilateral approach have a higher ratio of McKeown surgery, minimally invasive surgery and upper mediastinal lymph node dissection, shorter time of chest surgery and duration of postoperative hospital stay, better esophageal cancer specific survival rate. And there is no increase in perioperative risk.

High mobility group box protein 1(HMGB1)is one of the most widely expressed protein member in the HMGs family,which is well known for its involvement in the body inflammatory response.Previous researches have found that it plays a significant role in cell migration,immune identification and neuroprotection.Spinal cord injury is a disease that causes severe damage to the nervous system,and neural circuits are disrupted after a spinal cord injury,which leads to many conditions including ischemia and hypoxia,inflammatory responses,demyelinating lesions,and glial scar formation that are detrimental to nerve regeneration and repair,making it one of the most difficult diseases to treat in the modern spinal surgery field.HMGB1 is upregulated after spinal cord injury,thereby regulating neuroinflam-matory responses,and participating in the neuronal apoptosis,promoting neuronal regeneration,and inducing neural stem cell differentiation and migration,which plays an important role in the process of neural function recovery.This paper summarizes the structure and function of HMGB1,as well as its role in spinal cord injury,in order to provide direction for founding therapeutic target for neurological function recovery after spinal cord injury.

Aim To explore the effect of hydroxysafflor yellow A(HSYA)on lipocalin 2(LCN2)-induced fer-roptosis in HT22 cells and the related mechanism.Methods Thirty male Sprague-Dawley(SD)rats were used to establish the middle cerebral artery occlu-sion/reperfusion(MCAO/R)model by the suture method.The rats were randomly divided into the Sham group,the MCAO/R group,and the MCAO/R+HSYA group.The infarct area was measured by TTC staining,and the degree of neurological deficit was evaluated by the Z-Longa scoring method.The expressions of LCN2 and 24P3R in brain tissues were detected by Western blot.LCN2 protein was added to HT-22 cells,and the cells were divided into the normal group,the LCN2 group,and the LCN2+HSYA group.The optimal con-centration of LCN2-induced neuronal ferroptosis was screened by LDH assay and Western blot,and the ex-pression levels of ferritin,FPN1,GPX4,SLC7A11,COX2,and 24P3R were detected.LCN2 was knocked down by siRNA transfection,and the expressions of GPX4 and ferritin were detected.The contents of glu-tathione(GSH),malondialdehyde(MDA),GPX4,and Fe2+were determined by colorimetry,and the expres-sion of GPX4 was detected by immunofluorescence.The binding force between HSYA and LCN2 was ana-lyzed by molecular docking technology.Results Ani-mal experiments showed that HSYA could reduce the cerebral infarction area and decrease the neurological function score of MCAO/R rats.Compared with the sham group,the levels of LCN2 and 24P3R increased in the MCAO/R group,while HSYA inhibited their ex-pressions.Cell experiments showed that the optimal concentration of LCN2 to induce ferroptosis in HT22 cells was 2 μmol·L-1.After knocking down LCN2 by siRNA transfection,compared with the LCN2 group,the expression levels of GPX4 and ferritin in the siLCN2 group increased significantly.Compared with the nor-mal group,the expressions of SLC7A11,GPX4,FPN1,ferritin,and GSH in the LCN2 group decreased signifi-cantly,while the concentration of Fe2+,and the expres-sions of MDA,COX2,and 24P3R increased.HSYA could increase the expressions of SLC7A11,GPX4,FPN1,ferritin,and GSH,reduce the contents of Fe2+and MDA,and inhibit the expressions of COX2 and 24P3R.Molecular docking showed that the binding en-ergy between HSYA and LCN2 was-8.0 kJ·mol-1.Conclusion HSYA can inhibit LCN2-induced ferrop-tosis in HT22 cells through the SLC7A11/GPX4 signa-ling pathway.

As the first defense of respiratory system,airway epi-thelial cells(AECs)play an important role in separating the re-spiratory internal and external environment.They are essential for the natural immune function.Small airway lesions are an im-portant early pathology of chronic obstructive pulmonary disease(COPD),when AECs are exposed to harmful particles or gases for a long time,the epithelial barrier is damaged,and the signa-ling pathways which involved in differentiation,repair,and in-flammatory are disordered,resulting in epithelial cell cycle stag-nation and accelerated aging.A number of studies have sugges-ted that AECs of COPD patients express high levels of aging markers,suggesting that senescence of AECs is closely related to COPD.This review discusses the potential mechanisms of AECs senescence in COPD,the impact of AECs senescence on the de-velopment and severity of the disease,and highlights potential targets for modulating cellular senescence in airway epithelium as a therapeutic approach in COPD.
