      Objective To evaluate the long-term cost-effectiveness of opportunistic atrial fibrillation（AF）screening using a single-lead handheld ECG device among hospital-attending adults within an urban medical consortium．Methods No screening and opportunistic screening at different frequencies（quarterly，semiannual，and annual）were compared by a Markov model calibrated to Guangzhou-specific epidemiological data．From the healthcare provider perspective，we estimated costs and quality-adjusted life-years（QALYs），calculated incremental net monetary benefit（INMB）and incremental cost-effectiveness ratio（ICER），and performed probabilistic and scenario sensitivity analyses．Results The AF model demonstrated good predictive validity．Under the baseline scenario，quarterly screening was the optimal strategy，yielding a gain of 0.525 5 QALYs，cost savings of CNY 15 626.61，and an INMB of CNY 85 312.14 versus no screening．Sensitivity analyses indicated that adherence to anticoagulation had the greatest impact on cost-effectiveness．Scenario analyses varying diagnostic sensitivity and specificity did not change the conclusion regarding the optimal strategy．Conclusions In the context of an urban medical consortium，quarterly opportunistic AF screening based on a single-lead handheld ECG device for hospital-attending adults aged ≥65 years is robustly cost-effective．Integrating screening into tiered care with end-to-end management，while prioritizing adherence management，can maximize stroke-prevention benefits and improve resource allocation efficiency．

      目的 调查住院老年患者因经外周静脉置入中心静脉导管（PICC）而引发的血栓情况，并分析其影响因素，为老年患者置入PICC产生的相关性血栓（PICC-CRT）和症状性血栓的评估与干预提供借鉴。方法 在2023年1月—2023年12月期间，选取广州市第一人民医院接受PICC置管的317例住院老年患者。采用包括患者一般情况调查表、运动功能评定、肌力检测、 Barthel指数评定、Padua评分等多种工具进行综合评估。采用多因素 Logistic 回归构建 PICC-CRT 及症状性血栓的预测模型，并应用逐步回归法优化变量筛选过程。模型性能通过 ROC 曲线进行评估。结果 去除临床资料不完整的患者40例，最终纳入277例患者的完整资料，其中123例患者出现了PICC-CRT，发生率为44.40%（123/277）。血栓分级中，I级78例，Ⅱ级37例，Ⅲ级8例。无症状血栓83例，占67.48%，发生率29.96%（83/277）；症状性血栓40例，占32.52 %，发生率14.44%（40/277）。单因素分析联合多因素Logistic回归显示，卒中史、凝血酶原时间（PT）、导管留置时间是住院老年患者PICC-CRT的关键因素（P＜0.05），预测模型ROC曲线下面积为0.719；置管史、恶性肿瘤史、导管留置时间、置管后并发症数量是住院老年患者PICC症状性血栓的独立影响因素（P＜0.05），预测模型ROC曲线下面积为0.812。结论 文章总结了PICC-CRT和症状性血栓独特的影响因素，基于关键因素构建了预测模型预测其发生，为护理人员预防PICC-CRT和症状性血栓的发生提供了参考。

   Objective To explore the incidence of thrombosis associated with peripherally inserted central catheter（PICC）placement in hospitalized elderly patients and to analyze its influencing factors，in order to provide a reference for the assessment and prevention of PICC-catheter related thrombosis（PICC-CRT）and symptomatic thrombosis in this population．Methods A total of 317 elderly inpatients who underwent PICC placement at a tertiary hospital in Guangzhou between January and December 2023 were enrolled．Comprehensive assessments were conducted using general patient information forms，motor function evaluation，muscle strength testing，Barthel Index，and Padua score．Multivariate Logistic regression analysis was used to construct predictive models for PICC-CRT and symptomatic thrombosis，with variable selection optimized via stepwise regression．Model performance was evaluated using receiver operating characteristic（ROC）curve analysis．Results After excluding 40 patients with incomplete clinical data，277 cases were included in the final analysis．Among them，123 patients developed PICC-CRT，with an incidence rate of 44.40%（123/277）．Thrombosis was graded as Grade I in 78 cases，Grade II in 37 cases，and Grade III in 8 cases．Asymptomatic thrombosis occurred in 83 cases（29.96%），accounting for 67.48% of PICC-CRT；symptomatic thrombosis occurred in 40 cases（14.44%），accounting for 32.52%．Univariate and multivariate Logistic regression analyses identified history of stroke，prothrombin time（PT），and catheter dwell time as key risk factors for PICC-CRT（P＜0.05），with the area under the curve（AUC）of 0.719．History of catheterization，malignancy，catheter dwell time，and number of post-catheterization complications were independent predictors of symptomatic thrombosis（P＜0.05），with an AUC of 0.812．Conclusions This study identified distinct risk factors for PICC-CRT and symptomatic thrombosis in elderly inpatients．Predictive models based on key variables may provide useful references for clinical staff in preventing the occurrence of PICC-related and symptomatic thrombosis．

      目的 调查消化系统恶性肿瘤患者营养风险、营养知识-态度-行为（知信行）水平的现状，探究各因素是否对患者的营养风险、营养知信行水平具有影响，并分析两者之间的相关性。方法 选取中山大学附属第八医院（深圳福田）2024年2月—10月的244例消化系统恶性肿瘤患者为研究对象，采用一般资料调查表、营养风险筛查NRS2002量表以及消化系统肿瘤患者营养知信行问卷进行调查，数据收集后进行统计分析，从而研究消化系统恶性肿瘤患者营养筛查风险与营养知信行水平的现状、影响因素及两者间的相关性。结果 69.3%的消化系统恶性肿瘤患者存在营养风险，营养风险评分为（2.72±1.42）分。消化系统恶性肿瘤患者营养知识水平得分为（12.30±5.26）分、营养态度水平得分为（14.80±2.68）分、营养行为水平得分为（22.82±4.55）分、营养知信行水平总分为（49.96±9.50）分。家庭经济收入是患者营养风险水平的核心影响因素（P＜0.05），学历水平是患者营养知信行水平的核心影响因素（P＜0.05）。消化系统恶性肿瘤患者营养风险水平与营养知信行的总体水平呈负相关（r=-0.143，P＜0.05）。结论 消化系统恶性肿瘤患者的营养知信行水平总体处于中等水平，但普遍存在营养风险较高的情况。在患者治疗期间实施个性化营养健康宣教至关重要，这将有助于提升患者的营养知识水平，从而整体性改善其营养知信行素养并降低其营养风险，但在进行营养宣教和制定个性化营养方案时应充分考虑患者的家庭经济收入及学历水平。

    Objective To explore the nutritional risk and nutritional knowledge-attitude-behavior status of patients with digestive system malignant tumors，to analyze the influencing factors of nutritional risk，nutritional knowledge-attitude-behavior，and explore the correlation between them．Methods From February 2024 to October 2024，244 patients with digestive system malignant tumors at the Eighth Affiliated Hospital of Sun Yat-sen University were selected as the research subjects．A general information questionnaire，Nutritional Risk Screening 2002，and digestive system tumor patient nutrition knowledge-attitude-behavior questionnaire were used to study the influencing factors and correlations between the nutritional screening risk and nutritional knowledge-attitude-behavior in patients with digestive system malignant tumors．Results There were 69.3% of the patients with digestive system malignant tumors had nutritional risk score ≥3，and the overall score was（2.72±1.42）．The scores of nutritional knowledge，attitude，behavior and total score of digestive system malignant tumors patients were（12.30±5.26），（14.80±2.68），（22.82±4.55）and（49.96±9.50），respectively．Family economic income was the core influencing factors of nutritional risk in patients with digestive system malignant tumors，while educational level was the core influencing factor of nutritional knowledge-attitude-behavior in patients with digestive system malignant tumors．The nutritional risk level of patients with malignant tumors of the digestive system was significantly negatively correlated with the overall level of nutritional knowledge-attitude-behavior．Conclusions The nutritional knowledge-attitude-behavior level of patients with malignant tumors of the digestive system is generally at a medium level，but there is a widespread situation of relatively high nutritional risk．It is extremely important and necessary to conduct personalized nutrition knowledge education for patients during their treatment period，which will help enhance patients’ nutritional knowledge level，thereby comprehensively improving their nutritional knowledge-attitude-behavior literacy and reducing their nutritional risks．However，when conducting nutrition education and formulating personalized nutrition plans，the patient’s family economic income，medical payment methods and educational level should be fully considered．

   Objective To analyzes the current situation of hospital drug supply guarantee under the policy of centralized and volume-based procurement（hereinafter referred to as “central procurement”），and proposes optimization strategies and suggestions for the policy and guarantee．Methods By extracting the procurement data of drugs supplied through centralized procurement at Yubei District People’s Hospital in Chongqing from January 2023 to December 2024，descriptive statistical analysis of the drug supply situation through centralized procurement was conducted．Results Among the 416 selected drugs purchased，69 were in short supply during the contract period，with a shortage rate of 16.59%．The reasons for the shortage were related to the production capacity of the enterprise，seasonal demand fluctuations，strong seasonality，and mainly chronic diseases and anti-infective．Conclusions It is suggested to build a monitoring platform，improve the reporting system，formulate emergency plans，and evaluate the supply capacity to ensure supply．

       目的 探究1990—2023年中国人群下背痛（LBP）疾病负担，并预测2024—2040年LBP疾病负担发展趋势，为公共卫生政策制定提供数据支撑。方法 基于GBD2023数据库，采用Joinpoint模型、分解分析（decomposition analysis）量化我国LBP负担变化趋势，最后通过ARIMA（autoregressive integrated moving average model）模型预测未来趋势。结果 2023年我国LBP患病人数达9 532.40万人，发病人数为4 138.36万人，伤残调整生命年（DALYs），虽然患病人数、发病人数及DALYs绝对数较1990年显著增长，但年龄标准化率（ASR）均呈显著下降趋势（AAPC依次为-0.90%、-0.84%、-0.89%）。分解分析表明，人口年龄结构是我国LBP疾病负担增长的主要正向驱动因素，流行病学趋势变化对患病率和DALYs起关键抑制作用，且存在明显性别差异。ARIMA模型预测显示，2024—2040年男性和女性LBP相关ASR将持续下降，但我国女性LBP负担仍高于男性。结论 我国LBP负担沉重，受人口结构、性别差异、行为与职业等多方面因素影响，未来需通过分人群、分职业精准干预及多部门协同，持续降低疾病负担。

     Objective To explore the characteristics of disease burden of low back pain（LBP） in the Chinese population from 1990 to 2023，and predict its development trend from 2024 to 2040，so as to provide data support for the formulation of public health policies．Methods Based on the Global Burden of Disease Study 2023（GBD 2023） database，the Joinpoint model and decomposition analysis were adopted to quantify the changing trend of LBP burden in China．The autoregressive integrated moving average（ARIMA） model was used to predict the future trend，with the data for prediction stratified by gender and age group．Results In 2023，the number of LBP patients in China reached 95.3240 million，the number of incident cases was 41.3836 million，and the disability-adjusted life years（DALYs） were 10.6359 million person-years．Although the absolute numbers of prevalent cases，incident cases，and DALYs increased significantly compared with 1990，the age-standardized rates（ASRs） all showed a significant downward trend（average annual percentage changes were -0.90%，-0.84%，and -0.89%，respectively）．Decomposition analysis revealed that population age structure was the primary positive driving factor for the growth of LBP disease burden in China，while changes in epidemiological trends played a key inhibitory role in prevalence and DALYs，with significant gender differences．ARIMA model prediction indicated that the LBP-related ASRs would continue to decrease in both males and females from 2024 to 2040，but the LBP burden in females would remain higher than that in males in China．Conclusions The baseline burden of LBP in China is heavy，affected by multiple factors such as population structure，gender differences，behavioral and occupational factors．In the future，targeted interventions for specific populations and occupations，as well as multi-sectoral collaboration，are needed to continuously reduce the disease burden．

      Objective To perform accurate and efficient statistical analysis of EP09c in clinical studies of in vitro diagnostic reagents（IVDR）．Methods Bias quantification was performed on the difference plot using MedCalc．Bias quantification was conducted on the scatter plot using regression modeling in SPSS and MedCalc．The difference plot and scatter plot were employed to corroborate the accuracy of the bias quantification results．Results Difference plots demonstrated that the low-concentration data of the working sample exhibited a constant standard deviation distribution with a bias of 0.10（0.09，0.28），while the high-concentration data conformed to a constant coefficient of variation distribution with a bias of -5.0%（median：-7.2%，1.5%） or -3.2%（Hodges-Lehmann median：-5.5%，-0.8%）．Scatter plots confirmed that Passing & Bablok（P-B） regression and weighted least square（WLS） regression（weight 1/x_i ^1.4） were applicable to the data from the working sample，with the resulting regression equations being y=0.122+0.952x（R²=0.983） and y=0.269+0.977x（R²=0.981），respectively．Conclusions The results of bias quantification must be confirmed by difference plot and scatter plot，otherwise the correctness of the results cannot be assured．

      目的 探讨不同体质指数（BMI）分组成年1型糖尿病（T1DM）患者的临床特征以及超重/肥胖与心血管代谢危险因素之间的关系。方法 纳入2015年6月至2022年6月在广州市第一人民医院内分泌代谢科住院的268例成人T1DM患者。分为超重肥胖组（BMI≥24.0 kg/m²，41例）、体质量正常组（18.5≤BMI＜24.0 kg/m²，155例）和体质量过低组（BMI＜18.5 kg/m²，72例）。比较三组人口学、人体测量及代谢指标的差异，采用多元线性回归分析BMI与估算肾小球滤过率（eGFR）的关联。结果 超重肥胖组患者的特征表现为年龄更大、病程更长、体脂肪量更高、腹部皮下脂肪面积更大、腰围、臀围更大、合并高血压比例更高、收缩压更高、高密度脂蛋白胆固醇更低、eGFR更低、糖化血红蛋白（HbA1c）更低。多元线性回归分析显示，校正年龄、性别、病程后，BMI与eGFR呈负相关（β=-2.050，P=0.012）；进一步校正HbA1c、血压、血脂后，该关联不再显著。结论 超重/肥胖成人T1DM患者存在多重代谢异常聚集，BMI与eGFR的负向关联可能主要与血糖、血压、血脂等代谢因素有关。

Objective To investigate the clinical characteristics of adult patients with type 1 diabetes mellitus（T1DM）in different body mass index（BMI）categories and the associations of overweight and obesity with cardiometabolic risk factors．Methods A total of 268 adult T1DM inpatients from Guangzhou First People’s Hospital were enrolled．Patients were divided into three groups：overweight/obese（BMI≥24.0 kg/m²，n=41），normal-weight（18.5≤BMI＜24.0 kg/m²，n=155），and underweight（BMI＜18.5 kg/m²，n=72）．Demographic characteristics，anthropometric measurements，and metabolic parameters were compared among the three groups．Multivariable linear regression analyses were performed to evaluate the association between BMI and estimated glomerular filtration rate（eGFR）．Results Patients in the overweight/obesity group were characterized by older age，longer diabetes duration，higher body fat mass，larger abdominal subcutaneous fat area，greater waist and hip circumferences，a higher prevalence of hypertension，higher systolic blood pressure，lower high-density lipoprotein cholesterol levels，lower eGFR，and lower glycated hemoglobin（HbA1c）levels．Multivariable linear regression analysis demonstrated that BMI was inversely associated with eGFR after adjustment for age，sex，and diabetes duration（β=-2.050，P=0.012）．However，this association was no longer significant after further adjustment for HbA1c，blood pressure，and lipid parameters．Conclusions Overweight/obese adult T1DM patients exhibit clustering of metabolic abnormalities．The negative association between BMI and eGFR may be primarily mediated by metabolic factors such as hyperglycemia，hypertension，and dyslipidemia．

       目的  探讨TAP水平与乳腺癌分子亚型及临床病理参数之间的相关性。方法  以2021年3月—2025年1月期间收治的150例乳腺癌病例为样本，采用静脉采血方式测定TAP凝聚物表面积指标，通过免疫组织化学EnVision双步染色技术，对雌激素受体（ER）、雄激素受体（AR）、孕激素受体（PR）、Ki-67及p53等表达水平进行分析，采用荧光原位杂交（FISH）对人表皮生长因子受体2（HER2）基因扩增状态进行检测。结果  150例患者中，TAP强阳性131例，TAP弱阳性15例，TAP阴性4例，TAP阳性率97.33%。免疫表型：ER阴性43例，ER阳性107例；AR阳性133例，AR阴性17例；PR阴性60例，PR阳性90例；p53阳性73例，p53阴性77例；HER2强阳性41例，HER2弱阳性89例，HER2阴性20例；Ki-67增殖指数≥20% 116例，Ki-67增殖指数＜20% 34例。FISH对65例免疫组织化学检测结果为HER2（2+ ）的乳腺癌病例进行基因扩增状态分析，其中阳性7例，阴性58例。Ki-67高增殖组TAP表达水平显著高于低增殖组（P＜0.05）；不同临床分期患者TAP表达水平存在差异（P＜0.05）；三阴型、HER2阳性型、Luminal A型和Luminal B型的患者之间的TAP表达水平存在差异（P＜0.05），各分子分型（HER2阳性型、三阴型、Luminal A型和Luminal B型）与其对应非分型组的TAP表达均无统计学差异（均P＞0.05）。结论  TAP在乳腺癌中广泛表达，且与Ki-67增殖指数、临床分期呈正相关。虽然不同分子分型间TAP表达存在总体差异，但具体亚型对比未显示显著性，后期需扩大样本量验证。

       Objective  To explore the relationship between tumor abnormal protein（TAP）level and molecular typing and clinicopathological features of breast cancer．Methods  A total of 150 breast cancer cases admitted from March 2021 to January 2025 were enrolled in this study．The surface area of TAP condensates was measured using venous blood samples．The expression levels of estrogen receptor（ER），androgen receptor（AR），progesterone receptor（PR），Ki-67，and P53 were analyzed via immunohistochemistry（IHC）using the EnVision two-step staining technique．The amplification status of the human epidermal growth factor receptor 2（HER2+）gene was determined using fluorescence in situ hybridization（FISH）．Results  Among 150 patients，131 cases were strongly positive，15 cases were weakly positive and 4 cases were negative，with a positive rate of 97.33%．Immunophenotype：ER positive in 107 cases and ER negative in 43 cases，133 cases were  positive for AR and  17 cases were negative，PR was positive in 90 cases and negative in 60 cases，73 cases were positive for p53 and 77 cases were negative．HER2 is strongly positive in 41 cases，weakly positive in 89 cases and negative in 20 cases．There were 116 cases with Ki-67 proliferation index ≥ 20% and 34 cases with Ki-67 proliferation index ＜ 20%．Sixty-five cases of breast cancer HER2（2 ）were detected in the later stage．by FISH，of which 7 cases were positive and 58 cases were negative．The expression level of TAP in patients with high Ki-67 proliferation index was higher than that in patients with low Ki-67 proliferation index（P＜0.05）．The expression level of TAP in patients with different clinical stages was different（P＜0.05）．There were differences in TAP expression levels among patients with triple negative type，HER2 positive type，Luminal A type and Luminal B type（P＜0.05）．There was no statistical difference in TAP expression between each molecular type（triple negative type，HER2 positive type，Luminal A type and Luminal B type）and its corresponding non-typing group（all P＞0.05）．Conclusions  TAP is widely expressed in breast cancer，and it is positively correlated with Ki-67 proliferation index and clinical stage．Although there is a general difference in TAP expression among different molecular typing，the comparison of specific subtypes shows no significance，and it needs to be verified by expanding the sample size
