目的预测直径>10 mm(非T1a期)甲状腺乳头状癌(papillary thyroid carcinoma,PTC)患者侧颈区淋巴结转移(lateral lymph node metastasis,LLNM),并分析其转移模式。方法回顾性分析166例行甲状腺切除术合并侧颈区清扫术且病灶直径>10 mm的PTC患者资料;分析其临床病理特征及侧颈部各分区淋巴结转移模式。收集临床病理、超声特征及实验室检查结果等资料,利用单因素、多因素Logistic回归分析来评估与LLNM相关因素;在此结果上建立列线图模型,采用受试者工作特征(receiver operating characteristic,ROC)曲线评估其模型的准确性。结果LLNM最常见于Ⅲ区(38.1%),且两个区域转移模式(42.2%)最常见。当病灶位于腺体不同位置时,淋巴结转移模式差异无统计学意义(P>0.05)。多因素Logistic回归结果显示,病灶位置、游离三碘甲腺原氨酸(free triiodothyronine,FT3)、促甲状腺激素(thyroid stimulating hormone,TSH)、甲状腺过氧化物酶抗体(thyroid peroxidase antibodies,TPOAB)水平及中央区淋巴结转移(central lymph node metastasis,CLNM)数目均是LLNM的独立危险因素。列线图预测模型的曲线下面积为0.851,提示模型诊断准确度较高。结论基于临床病理、超声特征及实验室结果(CLNM数目、病灶位置、FT3、TSH及TPOAB水平)的列线图模型对预测直径>10 mm PTC患者LLNM表现良好,可用于临床应用指导。

本研究旨在探讨青花椒(Zanthoxylum schinifolium)在石漠土环境下的最优施肥量与最经济用量,以期为集约用肥促进生态功能和丰产性能的消长关系提供科学依据。青花椒是典型的喜肥浅根性香料植物,在石漠土中顽强生存,生态功能与经济产量都高度依赖于土壤培肥。研究通过结构化培肥方案,分析了不同施肥水平对石漠化地区青花椒的光合代谢能力、产量性状的影响,构造肥料效应方程求解经济产量和逐步寻优法获得最佳经济产量时的最优施肥量区间。结果表明:产量性状中,果柄长无显著差异,果穗果实数在各处理中无明显差异。果实大小处理6、8、12与处理1、2、7、13差异显著(PN>P_(2)O_(5),各试验因子之间存在正向互作效应,其互作效应为NP>NK>PK。获得的三元二次经济产量函数,通过求导计算的最高产量为2.736 kg/株。参考市场肥料成本,获得的最佳经济产量(1.515 kg/株),最优肥料配比为:尿素(N)232.98 g/株,磷(P_(2)O_(5))166.64 g/株,钾(K_(2)O)297.38 g/株。石漠土条件下的产量性状受结构供肥影响大,青花椒选择与经济产量高度关联的优先策略,光合代谢的调解补偿次之。结构化肥干预可影响叶的净光合速率,在调整生态功能的发挥起积极的平衡作用,但与某些深根系植物(如甘草)不同,不符合肥效边际报酬递减律。在三元肥的干预下,能较好的拟合肥料效应方程,可获得最优肥料配方区间,来指导生态功能植被兼用型的经济作物,进行生产性供肥方案参考。

Duchenne muscular dystrophy(DMD)is a severe neuromuscular disorder caused by mutations in the dystrophin gene,which encodes the essential protein *** genetic condition,affecting approximately 1 in 5000 male births worldwide(Birnkrant et al.,2018),is characterized by progressive muscle weakness and wasting,leading to premature death in the second or third decade of life(Farini et al.,2016).The absence of dystrophin protein causes instability in the sarcolemma,which predisposes individuals to myonecrosis and activation of inflammatory signaling ***,there is currently no effective cure for DMD,and glucocorticoid steroids are commonly used in clinical settings to delay symptom development(Merlini et al.,2003).
