Objective To investigate the screening results and factors affecting abnormal detection rates among high-risk groups of esophageal cancer and to explore effective intervention measures. Methods We investigated and collected the information on gender, education level, age, marital status, symptoms of reflux esophagitis (heartburn, acid reflux, belching, hiccup, foreign body sensation in the pharynx, and difficulty swallowing), consumption of pickled vegetables, salt use, and esophageal cancer incidence of villagers in a natural village in Wenfeng District, Anyang City, Henan Province. Changes in reflux esophagitis symptoms in the high-incidence area of esophageal cancer before and after 16 years were observed, and the relationship of such changes with esophageal cancer was analyzed. Results In 2008, 711 cases were epidemiologically investigated, including 213 cases with one of the symptoms of reflux esophagitis such as heartburn, acid reflux, belching, hiccups, foreign body sensation in the pharynx, and difficulty swallowing (sorted in accordance with the abovementioned symptoms; if there are multiple symptoms, then the former is taken); 55 cases with at least two related symptoms, among which the most symptom was heartburn in 108 cases (15.1%); followed by acid reflux, belching, etc. In 2024, the same group of people was investigated, and eight people were missing because of relocation. A total of 703 people were successfully investigated, of which 189 cases (26.8%) had one of the symptoms of reflux esophagitis, such as heartburn (sorted in accordance with relevant symptoms, if there are multiple symptoms, then the former will be selected); 167 cases (23.7%) had at least two related symptoms, among which the most symptom was heartburn in 139 cases (19.7%); followed by acid reflux. Over 16 years, among the 703 people investigated, 45 cases had esophageal cancer and they had one or more of the abovementioned symptoms. No significant differences in the reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.26); no significant differences in the composition of reflux esophagitis-like symptoms were found between 2008 and 2024 (P=0.299). Conclusion The detection rate of reflux esophagitis-related symptoms in the population in a high-risk area of esophageal cancer has not decreased in the past 16 years, and the high-risk factors still exist. Esophageal cancer is closely related to reflux esophagitis, and clinical practice can provide early diagnosis and treatment for high-risk population.

Objective To investigate the relationship between tooth loss and the occurrence of esophageal cancer in a natural village in Wenfeng District, Anyang City, Henan Province. Methods A prospective cohort study was conducted to observe the occurrence of tooth loss and esophageal cancer among the asymptomatic residents of the natural village for 16 years from January 2008 to July 2024. Data were analyzed by chi-square test, binary logistic regression, and restricted cubic spline. Results Among the total population of 711 cases, 136 cases were lost to follow-up and 575 cases were included in the final statistics, including 45 cases with esophageal cancer. Significant statistical difference was found between esophageal cancer patients with and without tooth loss (P<0.05). Logistic regression analysis showed that tooth loss was associated with the occurrence of esophageal cancer (OR=3.977, 95%CI: 1.543-10.255). After the adjustment for confounders, tooth loss remained significantly associated with the occurrence of esophageal cancer (OR=3.038, 95%CI: 1.035-8.914). A nonlinear dose-response relationship was observed between the number of teeth lost and the incidence of esophageal cancer. When the number of teeth lost was less than 12, the risk of esophageal cancer increased with the number of teeth lost. When more than 12 teeth were lost, the risk of esophageal cancer decreased as the number of teeth lost increased. Conclusion Tooth loss is a risk factor for the occurrence of esophageal cancer in this natural village. When the number of teeth lost is less than 12, the risk of esophageal cancer increases with the number of teeth lost.

Objective:To assess the relationship between basophil levels and mortality in patients with intra-abdominal infection.Methods:Information on patients with intraperitoneal infection admitted to the intensive care unit were extracted from the MIMIC database.A time-dependent Cox regression model was used to adjust for confounders associated with 28-day mortality.Propensity score matching(PSM)was used to balance the baseline differences be-tween groups with different basophil levels,and a restricted cube chart(RCS)was used to show the relationship between basophil count and 28-day mortality in patients with intra-abdominal infection.Results:A total of 4403 patients with intra-abdominal infection were enrolled in the MIMIC database.Patients with high basophil levels have lower mortality than those with low basophil levels.There was an L-shaped curve between basophil level and 28-day mortality,with a cut-off value of 0.47×109/L.Cox regression analysis showed that basophil levels were an independent protective factor for mortal-ity in patients with intra-abdominal infection after adjusting for potential confounders(HR=0.586,95%CI:0.443-0.769).Protective factors for death at basophil levels remained after PSM adjusted for potential confounders(HR=0.628,95%CI:0.470-0.832).Conclusion:Basophil level is an independent protective factor for mortality in patients with intra-abdominal infection,and basophil levels should be dynamically monitored to better evaluate the prognosis of patients.

Objective To conduct a rapid health technology assessment(rHTA)of the efficacy,safety,and cost-effectiveness of tirzepatide for the treatment of type 2 diabetes mellitus(T2DM),and to provide evidence for clinical medication.Methods PubMed,Web of Science,Embase,Cochrane Library,WanFang Data,CNKI databases,and health technology assessment(HTA)websites were searched to collect systematic reviews/Meta-analysis,pharmacoecomic literature and HTA reports of tirzepatide in the treatment of T2DM from inception to February 28,2025.Two researchers independently conducted literature screening,data extraction,and quality assessment,and then summarized and analyzed the results.Results A total of 13 articles were included,comprising 2 HTA reports,8 systematic reviews/Meta-analyses,and 3 pharmacoeconomic studies.In terms of efficacy,tirzepatide outperformed placebo or other antidiabetic drugs in reducing glycated hemoglobin(HbA1c),increasing the rate of HbA1c＜7％,lowering blood glucose,and reducing weight.The antihyperglycemic and weight-loss effects of tirzepatide were dose-dependent,and it also had certain advantages in reducing the risk of cardiovascular events and renal composite endpoint events.Regarding safety,the incidence of gastrointestinal adverse events in the tirzepatide group was higher than that in the placebo group and the insulin group,mainly manifested as diarrhea,nausea,and vomiting.However,it did not increase the risk of serious gastrointestinal adverse events,nor did it increase the risk of hypoglycemia and pancreatitis.In terms of cost-effectiveness,tirzepatide had cost-utility and cost-effectiveness advantages compared with semaglutide and other antidiabetic drugs.Conclusion Compared with other antidiabetic drugs,tirzepatide has better efficacy,safety,and cost-effectiveness in the treatment of T2DM.

Objective To explore the gender differences in the relationship between depressive symptoms and cognitive functions in patients with depression.Methods From January 2021 to June 2024,375 patients meeting the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)criteria for depression were selected by convenience sampling from the Affiliated Psychological Hospital of Anhui Medical University.Depressive symptom severity was assessed using the 24-item Hamilton depression scale(HAMD-24),while cognitive function was evaluated using a series of neuropsychological assessment tools,including the trail making test,logical memory,figure memory,digit symbol substitution test,digit span backward,and Wisconsin card sorting test.Network analysis was performed using R software to examine the relationships between symptoms and cognitive function.Results The core symptom factors and core cognitive domains for male depressive patients are sleep disturbances(strength=1.253)and information processing speed(strength=1.605),respectively;In contrast,female patients exhiboted emotional stagnation(strength=1.322)and working memory(strength=1.289).Sleep disturbances and emotional stagnation were the bridging nodes(bridge strength=1.253 and 1.322)for male and female patients,respectively.The correlation stability(CS)coefficients for the node strength centrality in male and female patient groups were 0.514 and 0.515,respectively,both exceeding threshold of 0.25,indicating good network stability.There were no significant differences between genders in terms of global network strength(male vs.female:2.22 vs.4.87;P=0.356)and edge weight distribution(P=0.293).Conclusion The network relationships between depressive symptoms and cognitive function in depression patients show significant gender differences.Sleep disturbance and information processing speed play central roles in males,whereas emotional retardation and working memory impairment are core features in females.These findings provide a theoretical basis for developing gender-specific intervention strategies.

Objective:To compare the significantly differentially expressed proteins in peripheral blood mononuclear cells between patients with different types of depressive disorders and normal participants and explore objective biomarkers with diagnostic significance.Methods:From March to May 2024, peripheral blood samples were collected from bipolar depression (BP), simple depression (DEP), persistent depressive disorder (PDD), and normal participants (NP) at the outpatient department of the Mental Health Center of Ningxia Medical University General Hospital. Using data-independent acquisition (DIA) quantitative proteomics technology, differentially expressed proteins were identified in the peripheral blood of patients with different types of depressive disorders and normal participants, conducting bioinformatics analysis to obtain candidate objective biomarkers, and finally identifying common and unique objective biomarkers for different types of depressive disorders. Data analysis was conducted using R software (version 4.0) and SPSS 27.0 software.Results:A total of 167 differentially expressed proteins were screened between BP and NP, 30 differentially expressed proteins were screened between DEP and NP, and 14 differentially expressed proteins were screened between PDD and NP.The differential proteins unique to the BP group were ARPC4 SPARC、MTPN、SNCA、YWHAH、MIF、COTL1, the differentially expressed proteins unique to the DEP group were RBBP9 APOF、S100A6, and the unique differential proteins in the PDD group were APOA5 CA1、IGLV3-25、APOC2.Conclusion:The objective biomarkers and signaling pathways obtained using DIA quantitative proteomics technology are of great significance for revealing the biological basis and diagnosing accurately of different types of depressive disorders.

Objective:To evaluate the sample preparation proficiency and storage proficiency of 11 clinical biobanks in Beijing through simulated experiments, and to establish an assessment method for the quality comparability of biological samples.Methods:An exploratory research design was adopted. In November 2023, artificial composite serum quality control materials containing six recombinant human protein markers—recombinant human alanine aminotransferase (rhALT), recombinant human aspartate aminotransferase (rhAST), recombinant human creatine kinase (rhCK), recombinant human creatine kinase-MB (rhCK-MB), recombinant human B-type natriuretic peptide (rhBNP), and recombinant human troponin I (rhTNI)—were distributed to 11 clinical biobanks in Beijing City. Sample preparation and storage followed the standardized operating procedures. Proficiency differences were assessed through statistical analysis.Results:Three-way repeated measures ANOVA revealed all six protein markers showed a declining trend over storage time in ultra-low-temperature environments ( F values 11.68-4 179.66, all P<0.01). However, neither long-term/temporary refrigerator types ( F values 0.01-1.23, all P>0.05)nor placement locations within refrigerators significantly affected the stability of these six proteins ( F valus 0.03-1.47, all P>0.05). The biases in detection results for rhALT, rhAST, rhTNI, and rhBNP at different storage time points were within the allowable bias limits for each item, supporting their use as markers for protein stability in biobank samples. All 11 institutions passed the storage proficiency assessment. In the preparation proficiency assessment, deviations were observed in post-preparation sample results, with a notably high out-of-control rate for rhCK (36.36%). Conclusion:Sample preparation proficiency can serve as a quality control metric for clinical biobanks. Future external quality assessment systems for biobanks should focus on sample preparation rather than storage processes.

Objective To observe the volume changes of brain regions and their correlation with cognitive function in temporal lobe epilepsy(TLE)patients.Methods Fifty TLE patients(TLE group)and 34 healthy controls(control group)were prospectively enrolled.Brain 3D-T1WI was collected,brain regions were delineated with automated segmentation technique,and hippocampus was segmented additionally with hippocampal brain template(HBT).The volume of brain regions were compared between groups,and the correlation of brain region volume with Montreal cognitive assessment(MoCA)score were analyzed.Results Compared with control group,in TLE group,bilateral cerebrum white matter,right globus pallidus,left posterior cingulate gyrus,left precentral gyrus,right fusiform gyrus,left cerebellum white matter,corpus callosum,left hippocampus(HBT segmentation and conventional segmentation)and right thalamus volumes decreased significantly(all P＜0.05),while right choroid plexus volume increased significantly(P＜0.05).The volume of left hippocampus(HBT segmentation)and right fusiform gyrus were both positively correlated with MoCA score in TLE group(r=0.335,0.376,P=0.009,0.007).Conclusion Widespread atrophy of brain regions could be seen in TLE patients,which were correlated with cognitive function.
