《流行病学》作为公共卫生与预防医学的主干课程,对于培养高质量公共卫生人才至关重要。在大数据、人工智能和互联网技术迅猛发展的时代背景下,传统的单一教学模式已无法满足现代医学教育的需求。线上线下混合教学模式逐渐成为高等医学教育的主要教学方式。这种模式结合了线上资源的丰富性和线下课堂的互动性,能够拓展教学内容,提高学生的自主学习能力。通过大数据分析和人工智能技术,可以提供个性化学习体验和实时反馈,优化教学效果。然而,这一模式在实际应用中仍面临诸如资源整合不够、师生互动不足等挑战。文章以广州医科大学为例,分析了《流行病学》课程中混合教学模式的优势与不足,并提出了针对性的改进建议。通过这些建议,旨在提升混合教学模式的有效性,为未来教学改革提供新的思路和参考。

Epidemiology,as a core course in public health and preventive medicine,is crucial for training high-quality public health professionals．With the rapid development of big data,artificial intelligence,and internet technologies,traditional single-mode teaching methods no longer meet the demands of modern education．The blended learning model,combining online and offline teaching,has gradually become a primary method in higher medical education．This model integrates the richness of online resources with the interactivity of offline classes,expanding instructional content and enhancing students' self-directed learning abilities．By leveraging big data analysis and artificial intelligence,personalized learning experiences and real-time feedback can be provided to optimize teaching effectiveness．However,this model still faces challenges such as inadequate resource integration and insufficient teacher-student interaction in practical application．This study uses a medical university as a case study to analyze the advantages and limitations of the blended learning model in epidemiology courses and proposes targeted improvement suggestions．The aim is to enhance the effectiveness of blended learning and provide new insights and references for future teaching reforms．

Objective To investigate the prevalence of fatty liver disease and influencing factors among employees of a water purification company in Guangzhou．Methods Employees of a water purification company in Guangzhou who participated in occupational health examinations in 2023 were selected as the study subjects．The subjects' general conditions,personal history,occupational history,BMI,blood pressure,blood biochemical indicators,and liver ultrasound images were collected．Descriptive analysis was used to analyze the prevalence of fatty liver disease in this population．The influencing factors of fatty liver were analyzed by single factor and multiple factor Logistic regression．Results A total of 1 217 subjects were included in this study,and 543 were diagnosed as fatty liver disease,with a detection rate of 44.62%．The results of single factor analysis showed that the occurrence of fatty liver was closely related to gender,age,BMI and hypertension（P<0.05）．The analysis of occupational hazard factors showed that,the detection rate of fatty liver disease was higher in people exposed to hydrogen sulfide and ammonia compared to non-exposed individuals（P<0.05）．The longer the working years,the higher the detection rate of fatty liver（P<0.05）．The levels of liver function,lipid metabolism,blood glucose and uric acid in workers with fatty liver were higher than those in workers without fatty liver（P<0.05）．Multivariate Logistic regression analysis showed that age,BMI,abnormal liver function,abnormal lipid metabolism,high blood glucose levels and hyperuricemia were independent influencing factors for fatty liver disease（P<0.05）．Conclusions The detection rate of fatty liver disease among employees of a water purification company in Guangzhou is high,and the occurrence of fatty liver disease is mainly related to factors such as age,BMI,abnormal liver function,abnormal lipid metabolism,high sugar levels and hyperuricemia．

目的 探讨动态对比增强磁共振成像（DCE-MRI）多参数定量特征对乳腺癌腋窝淋巴结转移（ALNM）风险的预测价值。方法 回顾性收集2020年3月—2022年11月在佛山市高明区人民医院经手术病理确诊的155例乳腺癌患者临床资料,根据患者是否发生ALNM分为ALNM 组（n=39）和无ALNM 组（n=116）。采用单因素分析和多因素Logistic回归分析乳腺癌发生ALNM的影响因素。结果 ALNM组和无ALNM 组患者的肿块质地、肿块直径、肿块部位、肿块形状、肿块内部强化特征等指标比较差异无统计学意义（t/χ²=2.249、0.977、1.369、0.524、2.158,P>0.05）。两组患者肿块表观扩散系数（ADC）值、腋窝淋巴结（ALN）短径、肿块边缘、动态增强时间-信号强度曲线（TIC）曲线等指标比较,差异有统计学意义（t/χ²=6.573、9.873、29.441、2.031,P<0.05）。二元Logistic回归模型结果显示,肿块ADC值、ALN 短径（≥5 mm）、TIC曲线（流出型）为乳腺癌ALNM发生的危险因素（OR=0.251、0.106、0.002,P<0.05）。结论 DCE-MRI多参数定量特征中,乳腺癌患者的肿块ADC值低、ALN 短径（≥5 mm）、TIC曲线（流出型）为乳腺癌ALNM发生的危险因素。

Objective To investigate the predictive value of multi-parameter quantitative features of dynamic contrast-enhanced magnetic resonance imaging（DCE-MRI）in the risk of axillary lymph node metastasis（ALNM）in breast cancer．Methods Clinical data of 155 patients with breast cancer diagnosed by surgery and pathology in Foshan Gaoming District People's hospital from March 2020 to November 2022 were retrospectively collected．According to whether the patients had ALNM,they were divided into ALNM group（n=39）and non-ALNM group（n=116）．Univariate analysis and multiple Logistic regression models were used to explore the influencing factors of ALNM in breast cancer．Results There was no significant difference in mass texture,mass diameter,mass location,mass shape and internal enhancement between the ALNM group and the non-ALNM group（t/χ²=2.249,0.977,1.369,0.524,2.158,P>0.05）．There were significant differences in ADC value,ALN short diameter,tumor margin and TIC curve between the two groups（t/χ²=6.573,9.873,29.441,2.031,P<0.05）．Binary Logistic regression model showed that ADC value,ALN short diameter（≥5 mm）and tumor margin（blur）were risk factors for the occurrence of breast cancer ALNM（OR=0.251,0.106,0.002,P<0.05）．Conclusions Among the multi-parameter quantitative features of DCE-MRI,the ADC value of breast cancer,the short diameter of ALN（≥5 mm）,and the edge of the tumor（blur）are the risk factors for the occurrence of ALNM in breast cancer．
