Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objective To analyze the epidemiologic burden of colorectal cancer in Xishan District, Kunming City, Yunnan Province from 2018 to 2020. Methods Indicators of epidemiologic burden were calculated, including incidence rate, mortality rate, age-specific incidence/mortality rates, potential years of life lost (PYLL), and disability-adjusted life years (DALY) based on the National Disease Control and Prevention Center’s "Cancer Information Registration and Reporting System" and "Cause of Death Registration System". Results From 2018 to 2020, the ASR (China) for the incidence of colorectal cancer in Xishan District, Kunming City increased from 25.27/10⁵ to 26.29/10⁵, while the ASR (China) for mortality decreased from 17.11/10⁵ to 16.03/10⁵. The PYLL in 2018–2020 were 1399.63, 1376.78, and 1571.56 person-years, respectively, whereas the DALY in 2018–2020 were 1927.74, 1875.05, and 1945.17 person-years, respectively. The morbidity, mortality, PYLL, and DALY were generally higher in males than in females over 45 years of age. Conclusion Given the parallel trends of persistent incidence risk and steadily declining mortality for colorectal cancer in Xishan District, Kunming City, a three-tier prevention and control system centered on "lifestyle intervention–regular screening–positive case tracking" should be established, with a focus on covering high-risk populations, particularly males over 45 years of age.

Aim To explore the specific mechanism by which scutellarin(Scu)antagonizes the injury of human aortic endothelial cells(HAEC)induced by 2,2-azobis(2-methylpropylimidate)dihydrochloride(AAPH)by regulating the protein kinase RNA-like endoplasmic reticulum kinase(PERK)-nuclear factor erythroid 2-related factor 2(NRF2)/ac-tivating transcription factor 4(ATF4)-C/EBP homology protein(CHOP)pathway.Methods HAEC were pre-pro-tected by Scu and then injured by AAPH to explore the molecular mechanism of Scu on HAEC injury.The cells were di-vided into control group,AAPH group,AAPH+Scu low,medium and high groups.The contents of superoxide dismutase(SOD),malondialdehyde(MDA),glutathione peroxidase(GSH-Px)and glutathione S-transferase(GSH-ST)in the cells were measured.The content of reactive oxygen species(ROS)in cells was detected by fluorescent probe,and the apop-tosis rate was detected by Annexin V-FITC/PI method.The mRNA expression of PERK and eIF2α in cells was detected by RT-qPCR.The protein expression of glucose regulated protein 78(GRP78),PERK,p-PERK,eukaryotic initiation factor 2α(eIF2α),p-eIF2α,ATF4,CHOP,Nrf2,Bcl-2,p53 up-regulated modulator of apoptosis(PUMA),Caspase-3 and Caspase-12 in cells was detected by Western blot.In order to further study the molecular mechanism of Scu against HAEC injury,gene silencing technology was used to inhibit the expression of PERK in HAEC.The cells were divided in-to five groups:control group,AAPH+si-con group,AAPH+Scu+si-con group,AAPH+si-PERK group,AAPH+si-PERK+Scu group.The mRNA expression of PERK and eIF2α in cells after si-PERK interference was detected by RT-qPCR.The protein expression of PERK,p-eIF2α,eIF2α,ATF4,CHOP,Nrf2,Bcl-2,PUMA,Caspase-3 and Caspase-12 in cells after si-PERK interference was detected by Western blot.Results The content of ROS and the rate of apoptosis were significantly reduced after Scu intervention(P＜0.01).Scu could down-regulate the mRNA expression of PERK and eIF2α,and down-regulate the protein expression of GRP78,p-PERK,p-eIF2α,ATF4,CHOP,PUMA,Caspase-3,Caspase-12 and up-regulate the protein expression of Nrf2 and Bcl-2(P＜0.01).After interference with si-PERK,there were significant differences in the protein expression of PERK,p-eIF2α,ATF4,CHOP,Nrf2,Bcl-2,PUMA,Caspase-3,Caspase-12,as well as the mRNA expression of PERK and eIF2α in cells compared to before interference(P＜0.01).It is proved that Scu could anti-endoplasmic role in reticulum stress and apoptosis,which is closely associated with the regula-tion of the PERK-Nrf2/ATF4-CHOP pathway.Conclusion Scu can effectively alleviate AAPH-induced injury to HAEC by regulating PERK-Nrf2/ATF4-CHOP pathways to inhibit endoplasmic reticulum stress and cell apoptosis.

OBJECTIVE: To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD. METHODS: A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot. RESULTS: Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01). CONCLUSION Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.

Objective To investigate the impact of vestibular dysfunction on various domains of cognitive function, providing a basis for developing comprehensive vestibular-cognitive intervention strategies. Methods A total of 33 patients with confirmed unilateral vestibular dysfunction treated at Eye & ENT Hospital, Fudan University between June 2024 and December 2024. Vestibular function was assessed using vestibular evoked myogenic potential (VEMP), caloric testing, video head impulse test (vHIT), and sensory organization test (SOT). Cognitive function was evaluated using mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA), Stroop color-word test, trail making test (TMT), and auditory verbal learning test (AVLT). Subjective symptoms were assessed using dizziness handicap inventory (DHI). Results In the vestibular function assessment of patients, abnormalities in caloric testing, utricle VEMP and saccule VEMP results were most common, with rates of 87.9%, 57.6%, and 66.7%, respectively; SOT abnormality primarily characterized by impaired vestibular function (21.2%). Spearman correlation analysis showed age, years of education, hearing ability, and emotional state were associated with overall or specific domains of cognitive function in patients. Greater vestibular dysfunction severity was associated with longer TMT-A time (r＝0.443，P＝0.010), most severe damage of short-term (r＝－0.405，P＝0.019) and long-term delayed recalls (r＝－0.537，P＝0.001). Patients with 31-60 of DHI scores showed longer TMT-A time than patients with 0-30 of DHI scores (P＝0.033). Conclusions Patients with vestibular dysfunction exhibit significant impairment in low-frequency semicircular canal and utricle function, which affects attention allocation, information processing speed, and memory performance in cognitive tasks.

With obesity rates climbing worldwide, metabolic and bariatric surgery has evolved over seven decades into a pivotal therapeutic approach for treating severe obesity and related disorders. Recent research highlights that new anti-diabetic and weight-loss drugs, especially GLP-1 receptor agonists (GLP-1 RA), are catalyzing a paradigm shift in obesity management. Within this context, the key scientific challenge in metabolic surgery is thoroughly investigating how pharmacological interventions and surgical procedures work together in weight management, especially evaluating if new drugs can match bariatric surgery's long-term effectiveness, complication management, and metabolic changes. Resolving this interdisciplinary debate will influence precision medicine in obesity treatment and reshape future multidisciplinary care models for metabolic disorders.
