       1型糖尿病（T1DM）是一种免疫介导的胰岛β细胞特异性破坏的自身免疫性疾病，全球发病率逐年上升。胰岛自身抗体（IAbs）是T1DM最可靠的生物标志物，用于早期预测和诊断。然而，传统的放射配体法（RBA）虽然具有高实验特异度，但在疾病特异度方面存在局限性，尤其是单抗体阳性的预测价值较低。近年来，电化学发光法（ECL）作为一种无放射性污染的新方法，能够区分高亲和力和低亲和力的IAbs，显著提高了疾病特异度。多项研究表明，ECL法在预测T1DM风险方面优于RBA法，特别是在单抗体阳性的情况下。本文综述了IAbs检测方法的进展及其在T1DM预测和诊断中的应用，强调了ECL法在提高疾病特异度方面的优势。

       Type 1 diabetes mellitus（T1DM）is  an  autoimmune  disease  characterized  by the immune-mediated destruction of pancreatic β-cells，with a rising global incidence．Islet autoantibodies（IAbs）are the most  reliable biomarkers for early prediction and diagnosis of T1DM．However，the traditional radio-binding assay（RBA），despite its high experimental specificity，has limitations in disease specificity，particularly in the predictive value of single autoantibody positivity．Recently，the electrochemiluminescence（ECL）method，a non-radioactive approach，has been developed to distinguish high-affinity from low-affinity IAbs，significantly improving disease specificity．Multiple studies have shown that the ECL method outperforms RBA in predicting T1DM risk，especially in cases of single autoantibody positivity．This review discusses the advancements in IAbs detection methods and their applications in T1DM prediction and diagnosis，highlighting the advantages of the ECL method in enhancing disease specificity．

      目的 分析儿童大环内酯类耐药重症肺炎支原体肺炎（SMPP）的危险因素,构建列线图预测模型。 方法 回顾性收集2023年1月—2024年9月在广州医科大学附属番禺中心医院儿科住院治疗的1 121例大环内酯类耐药肺炎支原体肺炎患儿入院初期的临床资料。按7∶3比例将患儿资料随机分为训练集（784例）和验证集（337例）。采用R4.4.1软件使用10重交叉验证最小绝对收缩与选择算法（LASSO）回归分析进行单因素变量筛选,采用Logistics回归分析建立预测模型, 绘制可视化列线图。使用受试者操作特征曲线（ROC）, 校准曲线、Hosmer-Lemeshow（HL）检验及临床决策曲线（DCA）分别评估模型的区分度、校准度和临床使用价值。 结果 在训练集中, LASSO回归结合Logistics回归分析结果显示,院前发热时间>5.5 d、谷丙转氨酶>14.5 U/L、乳酸脱氢酶>287.5 U/L、C反应蛋白>18.65 mg/L、肺实变、合并病毒感染是大环内酯类耐药SMPP发生的危险因素（P<0.05）, 根据上述危险因素构建列线图预测模型。训练集和验证集ROC曲线下面积分别为0.847和0.822; 校准曲线和HL检验显示模型具有良好的校准度; DCA显示预测模型在风险阈值为0.05~0.95时预测性能最优。 结论 院前发热时间、谷丙转氨酶、乳酸脱氢酶、C反应蛋白、肺实变、合并病毒感染是大环内酯类耐药SMPP发生的影响因素, 基于以上因素构建的列线图模型具有较好的预测效能, 有利于早期识别耐药重症病例, 及早采取有效干预,改善患者预后。

      Objective To explore the risk factors and to construct a nomogram prediction model for severe macrolide-resistant Mycoplasma pneumoniae pneumonia（MPP）in children．Methods The clinical data during the initial admission period of 1 121 children with macrolide-resistant MPP who were hospitalized in the Department of Pediatrics of the Affiliated Panyu Central Hospital of Guangzhou Medical University from January 2023 to September 2024 were retrospectively collected．The children data were randomly divided into a training set（n=784）and a validation set（n=337）at a ratio of 7∶3．With R language software（version 4.4.1）, least absolute shrinkage and selection operator（LASSO）regression analysis with tenfold cross-validation was used to screen risk factors, Logistics regression analysis was used to establish prediction model, and a visualization of the risk variables was created using a nomogram．The receiver operating characteristic（ROC）curves, calibration curves, Hosmer-Lemeshow（HL）test and clinical decision curve analysis（DCA）were used to evaluate the discrimination, calibration and clinical application value of the model．Results In the training set, LASSO regression analysis combined with Logistics regression analysis showed that prehospital fever duration > 5.5 days, alanine aminotransferase level> 14.5 U/L, lactate dehydrogenase level> 287.5 U/L, C-reactive protein > 18.65 mg/L, lung consolidation, and co-infection with virus were risk factors for severe macrolide-resistant MPP（P<0.05）．A nomogram prediction model was constructed based on the above risk factors．The area under the ROC curves of the training set and the validation set were 0.847 and 0.822, respectively．The calibration curves and HL test showed that the model had good calibration． The DCA curves showed that the prediction model had the best prediction performance when the risk threshold was between 0.05-0.95．Conclusions Prehospital fever duration, alanine aminotransferase level, lactate dehydrogenase level, C-reactive protein level, lung consolidation and co-infection with virus were risk factors for prediction of severe macrolide-resistant MPP．The nomogram model based on the above factors had a good prediction efficiency, which was conducive to early identification of severe cases with macrolide-resistant, and taking early effective interventions to improve the prognosis．

      目的   残余胆固醇（RC）是反映动脉粥样硬化性血脂异常的重要指标，其在糖尿病合并冠心病患者中的临床意义尚不明确。本研究旨在探讨RC水平对糖尿病合并冠心病患者心力衰竭风险的预测价值，并分析其相关性。方法   本研究为回顾性横断面研究，纳入2021年1月—2024年1月期间在鹤壁市人民医院接受诊治的292例糖尿病合并冠心病患者。根据是否存在心力衰竭分为心力衰竭组（128例）和无心力衰竭组（164例）。对基线特征进行比较，采用单因素和多因素Logistic回归分析RC与心力衰竭的相关性。同时，通过限制性立方样条（RCS）分析探讨RC与心力衰竭风险的线性关系，并通过受试者操作特征（ROC）曲线和曲线下面积（AUC）评估RC的预测价值。结果   心力衰竭组患者的男性比例、高血压患病率、RC水平等高于无心力衰竭组，而估算肾小球滤过率水平显著降低（P＜0.05）。单因素分析显示，RC＞0.7 mmol/L显著增加心力衰竭风险（OR=1.854，95%CI：1.161~2.960，P=0.010）。多因素Logistic回归分析中，全调整模型结果显示，RC作为分类变量时，RC＞0.7 mmol/L的患者心力衰竭风险显著增加1.891倍（OR=1.891，95%CI：1.047~3.415，P=0.035）；作为连续变量时，RC每增加1单位，心力衰竭风险增加2.464倍（OR=2.464，95%CI：1.495~4.064，P＜0.001）；Log₁₀RC的风险比为6.411（95%CI：2.246~18.302，P=0.001）；标化RC的风险比为1.687（95%CI：1.262~2.255，P＜0.001）。限制性立方样条分析表明RC与心力衰竭风险呈线性正相关，ROC分析显示RC预测心力衰竭的AUC为0.621（95%CI：0.555~0.687，P＜0.001）。结论  RC水平与糖尿病合并冠心病患者心力衰竭风险显著相关，且呈线性正相关。RC具有一定的预测价值，可作为该人群心力衰竭风险评估的潜在指标。

       目的   调查江西省南昌市东湖区孕妇2022—2024年碘营养状况与盐碘监测情况，为区域干预提供依据。方法   将江西省南昌市东湖区划分为东、南、西、北、中5个片区，每个片区随机抽取一个街道（管理处），于每年5月份随机抽取各街道（管理处）20名孕妇，每年共抽取100名孕妇，3年共计300名孕妇，采集其尿液样本和家中食用盐样本检测碘含量，以统计学方法进行分析。结果  3年来孕妇家庭食用盐碘含量中位数为23.02 mg/kg，碘盐覆盖率为98.67%，碘盐合格率为95.33%，3年的食用盐碘含量比较差异有统计学意义（H=38.545，P＜0.05）。孕妇的尿碘水平中位数为115.15 μg/mL，3年来孕妇的尿碘水平中位数均低于150 μg/mL，有62.67%的孕妇碘缺乏，3年间的尿碘水平比较差异有统计学意义（H=9.392，P＜0.05），其中2024年的尿碘水平中位数为140.00 μg/mL，校正后高于2022年（Z=2.693，P＜0.0167）和2023年（Z=2.590，P＜0.0167）。Spearman相关性分析结果显示孕妇尿碘水平与盐碘含量及碘盐质量均无相关性（均P＞0.05），孕妇碘营养状况与盐碘含量及碘盐质量均无相关性（均P＞0.05），孕妇尿碘水平与碘营养状况正相关（r_s=0.857，P＜0.05），盐碘含量与碘盐质量正相关（r_s=0.314，P＜0.05）。结论   江西省南昌市东湖区2024年孕妇碘缺乏有所改善，但整体形势严峻，超半数的孕妇碘缺乏，食用碘盐基本符合国家消除碘缺乏病标准，但仍需改进。卫生部门要强化孕妇碘营养监测，向孕妇科普碘缺乏病知识，增强补碘意识，促其科学补碘。盐业监管部门需加大监管，严控碘盐质量，确保东湖区居民食盐合格。

自发性脑出血由于外伤性原因引起脑实质出血作为神经系统急危重症,该患病率约占所有脑卒中的10%~15%, 具有高患病率、高死亡率、高致残率的特点, 随着年龄的不断增长血管逐渐变薄、失去弹性,受到外在原因干扰时, 导致出血, 形成血肿, 依据血肿的不同程度, 患者的生存及预后有着显著的差异。因此快速且及时识别自发性脑出血尤为重要,可为临床医生评估患者病情变化及预后具有重要指导的意义, 然而在临床实践过程中对于快速识别脑出血的方法有所欠缺, 需要进一步优化其监测方法。因此本文综述了自发性脑出血的监测方法, 探讨通过无创监测、有创监测及联合监测自发性脑出血为临床快速高效判断脑出血提供科学的依据和参考。

The incidence of spontaneous cerebral hemorrhage accounts for about 10% to 15% of the stroke cases, and it has the characteristics of high incidence, high mortality rate, and high disability rate．It is very important to quickly identify spontaneous cerebral hemorrhage, which has important guiding significance for clinical doctors to evaluate patient condition changes and prognosis．This article reviews the latest research on non-invasive monitoring, invasive monitoring, and combined monitoring of spontaneous cerebral hemorrhage.
