Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

Objective: To investigate the prevalence and influencing factors of the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province, so as to provide evidence for comprehensive interventions on physical and mental health among adolescents. Methods: From September to December 2024, a multi stage random cluster sampling method was used to select 103 225 junior and senior high school students from 16 prefecture level cities in Anhui Province. Data were collected through questionnaire surveys and physical measurements. Elevated blood pressure was determined according to the Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years. Depressive symptoms among middle school students were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Chi-square test, Chi-square test for trend, and multivariate Logistic regression model were used to analyze the risk factors for the co-occurrence of elevated blood pressure and depressive symptoms. Results: The detection rate of elevated blood pressure was 15.22%, the detection rate of depressive symptoms was 18.56%, and the co-occurrence rate of the two conditions was 2.67% among junior and senior high school students. Multivariate Logistic regression analysis showed that after controlling for gender, school stage, household registration, and overweight and obesity status,compared with those who don t drink sugary drink and eat fried food, and get enough sleep, sugar sweetened beverage intake <1 and ≥1 time/d( OR =1.28,1.61), fried food consumption ≥1 time/d( OR =1.37), and insufficient sleep ( OR =1.54) were all associated with an increased risk of the co-occurrence of elevated blood pressure and depressive symptoms(all P <0.05). Daily fresh vegetable intake ≥1 time/d( OR =0.78) and fresh fruit intake ≥1 time/d( OR =0.85) were both associated with a decreased risk of the co-occurrence(both P <0.05). Compared with students who did not eat breakfast, students who ate breakfast sometimes and every day ( OR =0.62,0.36) had a lower co-occurrence risk(both P < 0.05). Junior and senior high school students with daily outdoor activity duration≥1 h ( OR =0.81) had a lower risk of the co-occurrence of elevated blood pressure and depressive symptoms ( P <0.05). Conclusions Sugar sweetened beverage drink and fried food consumption, inadequate consumption of fresh vegetables, fruits and breakfast, lack of outdoor activity, and insufficient sleep are risk factors for the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province. It is necessary to establish school health promotion strategies integrating nutrition, exercise and sleep management as intervention targets to reduce the co-occurrence risk of elevated blood pressure and depressive symptoms among junior and senior high school students.

Objective To investigate the role of reactive oxygen species(ROS)and the extracellular signal-regulated kinase(ERK)/cAMP response element binding protein(CREB)signaling pathway in arsenic-induced apoptosis in HT-22 cells.Methods HT-22 cells were cultured in vitro and exposed to NaAsO2.The cells were divided into the following groups:control group,4,6,8,and 10 μmol/L NaAsO2 groups,NAC(5 mmol/L)group,and NAC(5 mmol/L)+NaAsO2(10 μmol/L)group.ROS levels were measured using a DCFH-DA assay.The expression of ERK/CREB signaling pathway-related and apoptosis-related proteins were analyzed by Western blotting.Apop-tosis rates were evaluated using flow cytometry.Results Compared with the control group,ROS levels in HT-22 cells significantly increased,while p-ERK protein level in the nucleus and p-CREB and Bcl-2 protein levels in the cells significantly decreased in the NaAsO2 only exposed groups(P＜0.05).Additionally,the apoptosis rate significantly increased in the 8 and 10 μmol/L NaAsO2 groups compared with the control group(P＜0.05).In the NAC+NaAsO2 group,ROS levels and the apoptosis rate significantly decreased while p-ERK protein level in the nucleus and p-CREB and Bcl-2 protein levels in the cells significantly increased compared with the 10 μmol/L NaAsO2 group(P＜0.05).Conclusion Arsenic exposure induces oxidative stress,inhibits the nuclear translocation of p-ERK,and dis-rupts the CREB signaling pathway,leading to apoptosis.

Malignant tumors(commonly referred to as cancers)represent a major global public health challenge and contribute substan-tially to the global disease burden.Early screening plays a crucial role in improving detection rates,enabling timely intervention,and enhan-cing patient survival.However,current cancer screening guidelines primarily focus on site-specific screening,which may not fully address the need for comprehensive early detection.A scientifically rational,multi-cancer screening approach offers several advantages:it optimizes the use of biological samples,reduces the time burden for participants,enhances the efficiency and comprehensiveness of screening,and min-imizes overall expenses.Moreover,this approach facilitates rational allocation of healthcare resources,ultimately helping to reduce the soci-etal burden of cancer.To address gap,the Cancer Epidemiology Committee of the China Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers.This consensus integrates multidisciplinary expertise and synthesizes the latest do-mestic and international researches on cancer screening,early detection,and treatment of prevalent malignancies.Drawing upon China's unique demographic and healthcare context and practical screening experiences,the consensus provides evidence-based recommendations on target populations,screening technologies,and procedural workflows for multi-cancer screening.These guidelines align with the prin-ciples and methodologies established by the World Health Organization(WHO),aiming to enhance the effectiveness of combined cancer screening in China,improve early detection rates,and provide a scientific foundation for national cancer prevention and control strategies.

Objective: Uterine cancer (UC) is a major cause of cancer-related deaths among women. This study assesses the global burden of UC from 1990 to 2021. Methods: Data from the Global Burden of Disease 2021 study were used to analyze UC incidence, mortality, and disability-adjusted life years (DALYs) across 204 countries.Age-standardized rates were evaluated by age and Socio-Demographic Index (SDI), with trends forecasted to 2036 using Bayesian models. Results: In 2021, the global incidence of UC reached 473,614 cases (95% uncertainty interval [UI]=4,29916–5,13667), with an age-standardized incidence rate of 5.41 per 100,000 (95% UI=4.90–5.87), showing an upward trend since 1990, particularly in high-SDI regions. However, the mortality rate in high SDI regions exhibited a declining trend, with an estimated annual percentage change (EAPC) of −0.25 (95% confidence interval=−0.42 to −0.08). Although the number of deaths globally has increased, the age-standardized mortality rate has decreased compared to 1990 (EAPC: −0.85). The global age-standardized DALYs also show a downward trend, except in high SDI and low-middle SDI regions. The highest incidence was observed among individuals aged 70–74 in 2021. By 2036, new cases are projected to rise, though incidence, mortality, and DALYs are expected to decline. Conclusion Regional disparities in the global UC burden highlight the need for tailored strategies, especially in low-income countries, to reduce its impact.

Cervical cancer (CC) is a significant cause of cancer-related deaths in women and ranks as the fourth most common malignant tumor worldwide. Cervical histopathology is currently the primary diagnostic method for confirming the presence of CC. Tumor markers and imaging techniques play crucial roles in monitoring treatment effectiveness and prognostic follow-up. Unfortunately, these traditional examination methods are invasive and often lack sensitivity and accuracy. Therefore, there is a need for a less invasive and more sensitive test to facilitate early diagnosis, efficacy evaluation, and prognostic monitoring of CC. In recent years, liquid biopsy has been developed as a new detection method. It involves analyzing tumor components released into the peripheral circulation, such as cell-free RNA, circulating tumor DNA, circulating tumor cells, tumor-educated platelets, and exosomes. Liquid biopsy offers advantages such as being less invasive, highly reproducible, and capable of real-time monitoring. Moreover, liquid biopsy can play a crucial role in the early diagnosis of CC, guiding targeted therapy, assessing prognosis, and evaluating treatment effectiveness.This review focuses on the value of liquid biopsy application in CC, detection markers, and detection methods. It also explores how liquid biopsy can be used in the detection, prognosis, and monitoring the progression of CC. The advantages and limitations of liquid biopsy in CC are analyzed to promote its application and improve the diagnosis and treatment of the disease.

Purpose The study aimed to analyze the relationship between MET gene variants and clinicopathologi-cal features in patients with non-small cell lung cancer(NSCLC).Methods Next-generation sequencing technology was used to detect MET gene variants in NSCLC specimens.The association between MET gene variant status and clini-copathological features was then analyzed.Results Among 1 633 cases of NSCLC,the overall MET mutation rate was 4.53％(74/1 633).Variants were mainly observed in male patients,never-smokers,those older than 60 years,ade-nocarcinoma histology,and patients with TNM stage Ⅲ+Ⅳ disease(P＜0.05).MET gene variant status showed no significant assocication with patient age,sex,smoking history,or pathological subtype(P＞0.05),but was statistical-ly correlated with clinical stage and presence of distant metastasis(P＜0.05).The two major variant types were MET exon 14 skipping and MET amplification,which together accounted for 71.62％of all variants.In addition,MET am-plification was positively correlated with EGFR(P=0.003,rs=0.340)and TP53 mutations(P=0.002,rs=0.362),but showed no correlation with KRAS or ALK gene mutations.In contrast,MET exon 14 skipping was nega-tively correlated with EGFR gene mutations(P＜0.001,rs=-0.409),and showed no significant correlation with KRAS,ALK,or TP53 mutations.Conclusion Different types of MET gene variants(amplification,exon 14 skip-ping,fusion,and others)are significantly associated with clinical advanced clinical stage and distant metastasis in NSCLC,but are independent of patient age,sex,smoking history,and pathological subtype.MET amplification fre-quently co-occur with EGFR and TP53 co-mutations.

Objective A rat model of cerebral small vessel disease(CSVD)was established by unilateral injection of a single dose of sodium laurate into the internal carotid artery.The effectiveness of the model was assessed by behavior scoring and analysis of serum-related indicators,cerebral infarction volume,cerebral microvascular density,hemodynamics,brain histopathology and the expression of blood-brain barrier(BBB)-related proteins.Methods SPF-grade male SD rats were divided randomly into a control group and a model group(n=6 per group).The model group received a single injection of 100 μL of sodium laurate(2 g/L)via the internal carotid artery,while the control group underwent the same surgical procedure but received an equal volume of saline.Neurobehavioral assessments were conducted using the Longa score and postural reflex test.Serum homocysteine(HCY)levels were measured by enzyme-linked immunosorbent assay.Cerebral infarction volume was detected by magnetic resonance imaging and changes in cerebral vascular density were observed by cerebrovascular imaging.The resistance index(RI)and perfusion index(PI)were measured by ultrasonography.Histopathological changes in brain tissue were evaluated by hematoxylin and eosin(HE)staining.Expression of the cerebral microvascular marker CD31 and tight junction proteins ZO-1 and Occludin in brain cortex tissue were detected by immunohistochemical staining.Results The Longa score,postural reflex score(P＜0.05),and cerebral infarction volume were significantly increased(P＜0.05)while the cerebral vascular density was decreased in the model group compared with the control group.Serum HCY levels,carotid RI,and PI values were all significantly increased in the model group(P＜0.05).HE staining revealed solidified neuronal nuclei and enlarged perivascular spaces in the brain cortex in the model group.Immunohistochemical staining revealed that CD31,ZO-1,and Occludin expression were significantly reduced in the brain cortex in the model group compared with the control group(P＜0.05).Conclusions A rat model of CSVD can be established rapidly and effectively by a single unilateral injection of high-concentration sodium laurate via the internal carotid artery.This model is characterized by neurobehavioral abnormalities,cerebral infarction,insufficient cerebral blood supply,reduced vascular density,and disruption of the BBB,suggesting that it may serve as an effective rat model for the study of CSVD.
