目的探究美国放射学会(ACR)提出的甲状腺影像报告和数据系统(TIRADS)与欧洲甲状腺协会提出的TIRADS(简称EU-TIRADS)在甲状腺结节(TN)诊断中的一致性及差异原因。方法回顾性分析2019年6月至2022年1月于来安家宁医院(272例)和南京医科大学附属南京医院(10例)经细针穿刺活检或手术组织病理学检查结果确诊的282例TN患者的年龄、性别、TN情况(大小、个数、结构、回声、形状、边缘、钙化)、ACR-TIRADS和EU-TIRADS检查结果等资料,其中男性72例、女性210例,年龄(45.9±10.9)岁。计量资料的组间比较采用两独立样本t检验;计数资料的组间比较采用χ^(2)检验。采用McNemar配对χ^(2)检验比较二者的诊断准确率;采用多分类资料的Kappa检验进行一致性分析;以2种系统检查结果相符为A组,不相符为B组,比较2组的超声诊断特征;采用多因素Logistics回归预测模型分析2种系统检查结果不相符的独立危险因素;采用临床决策曲线评价模型的精准度。结果TN的恶性风险均随着ACR-TIRADS和EU-TIRADS分类类别升高而增加。二者相比,EU-TIRADS较ACR-TIRADS的灵敏度更高(91.54%对79.31%),差异有统计学意义(χ^(2)=19.135,P<0.001);ACR-TIRADS较EU-TIRADS的特异度更高(75.67%对62.38%),差异有统计学意义(χ^(2)=12.900,P<0.001)。ACR-TIRADS 2~4类无论是良性还是恶性TN均与EU-TIRADS 2~4类一致性良好。Logistic回归分析结果显示,结节长径<20 mm(OR=1.196,95%CI:1.005~1.422,P<0.001)、海绵样结节(OR=1.119,95%CI:1.022~1.226,P=0.016)、低和(或)中低回声(OR=1.627,95%CI:1.031~1.732,P=0.011)、圆形(OR=1.072,95%CI:1.012~1.134,P=0.022)、边缘模糊(OR=1.567,95%CI:1.063~1.683,P<0.001)、微分叶边缘(OR=1.169,95%CI:1.051~1.301,P=0.004)均是二者检查结果不相符的独立危险因素。结论EU-TIRADS较ACR-TIRADS对TN诊断的灵敏度高、特异度低;二者对2~4类TN的检查结果一致性良好。

目的探讨精蛋白生物合成人胰岛素、地特胰岛素分别联合门冬胰岛素对妊娠期糖尿病(GDM)孕妇糖脂代谢及母婴结局的影响,以期为临床治疗提供参考。方法本研究选取2021年1月—2023年12月遂宁市中医院收治的120例GDM孕妇为研究对象。采用随机数字表法将孕妇分为观察组与对照组,每组60例。2组孕妇均给予门冬胰岛素治疗。对照组孕妇在门冬胰岛素应用基础上给予精蛋白生物合成人胰岛素治疗;观察组孕妇在门冬胰岛素应用基础上联合地特胰岛素治疗。2组孕妇均以治疗2周为1个疗程,比较治疗前、治疗4个疗程时的血糖控制情况[空腹血糖(FPG)、糖化血红蛋白(HbA1c)、餐后2h血糖(2hFPG)]、血脂水平[总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)]及胰岛素相关指标[胰岛素抵抗指数(HOMA-IR)、胰岛β细胞功能指数(HOMA-β)、空腹胰岛素水平(FINs)]水平变化。比较2组孕妇低血糖事件发生情况及母婴结局。结果治疗前,2组孕妇FPG、2h-PBG、HbAlc水平比较,差异无统计学意义(P>0.05)。治疗4个疗程时,2组孕妇FPG、2h-PBG、HbAlc水平均低于治疗前,且观察组低于对照组,差异均有统计学意义(P0.05)。治疗4个疗程时,2组孕妇TC、LDL-C水平均低于治疗前,且观察组低于对照组,差异有统计学意义(P0.05)。治疗4个疗程时,2组孕妇HOMA-IR及FINs水平均低于治疗前,且观察组低于对照组,差异均有统计学意义(P0.05)。2组孕妇剖宫产、胎膜早破发生率及总发生率比较,差异均无统计学意义(P>0.05)。2组新生儿早产、高胆红素血症、巨大儿发生率及总发生率比较,差异均无统计学意义(P>0.05)。结论地特胰岛素联合门冬胰岛素可有效改善GDM孕妇血糖、血脂水平,恢复胰岛β细胞功能,提高临床疗效,且不增加低血糖及不良妊娠结局风险,值得推广。

目的分析工业园区作业工人认知功能现状,阐明在不同认知功能水平下,相关因素对作业工人认知功能的影响。方法2022年3—7月采用整群抽样方法在宁夏回族自治区某工业园区抽取18~60岁的作业工人进行问卷调查和体格检查,运用简易智力状态检查量表(mini-mental state examination,MMSE)评估作业工人的认知功能。非参数检验比较不同特征下作业工人认知功能得分差异,运用分位数回归模型分析作业工人认知功能在不同分位数上的影响因素。结果1785名作业工人认知功能评分的M(P_(25),P_(75))为16.00(14.00,17.50)分。文化程度在5%、25%、50%、75%、95%分位点的回归系数(β)分别为0.449、0.412、0.288、0.231、0.361(P均<0.05)。50%分位数回归显示,年龄、文化程度、是否有夜班、体育锻炼、阅读书报存在统计学意义,高龄(β=0.055,P<0.05)、有夜班(β=0.359,P<0.05)是作业工人认知功能的危险因素;较高的文化程度(β=0.288,P<0.05)、经常锻炼(β=0.342,P<0.05)、良好的阅读习惯(β_(偶尔)=0.348,P<0.05;β_(经常)=0.775,P均<0.05)是作业工人认知功能的保护因素。结论不同影响因素在作业工人认知功能的不同分位数水平,其作用模式是不同的,多数自变量的显著性或回归系数大小发生改变,应采取个体化的预防策略促进作业工人健康、提高职业生命质量。
