Zhongshan Daxue xuebao. Yixue kexue ban, 2019 【目的】探究甲状腺乳头状癌（PTC）颈侧区淋巴结转移的临床特征。【方法】回顾性分析皖南医学院附属弋矶山医院2011年6月1日至2018年5月30日收治的PTC患者临床资料。【结果】本研究共纳入241例病例。术后常规病理证实颈侧区淋巴结转移率73.44%（177/241）。与颈侧区淋巴结无转移的PTC患者相比，伴颈侧区淋巴结转移的PTC患者年龄偏小，多为女性，癌肿直径较大，颈中央区淋巴结转移数目较多，超声及CT检查积分更高。而BMI指数、桥本氏甲状腺炎病史及甲亢病史对PTC颈侧区淋巴结转移率无显著性影响。【

DWI对鼻咽癌颈部小淋巴结转移瘤的诊断价值及其对放疗靶区的优化
Zhongguo shiyan zhenduanxue, 2021 目的探讨磁共振扩散加权成像（DWI）对鼻咽癌（NPC）小淋巴结转移瘤的诊断价值和NPC小淋巴结转移瘤表观扩散系数（ADC）的诊断阈值,及其对放疗靶区的优化。方法选取2017年9月至2019年12月广西科技大学第二附属医院收治的72例NPC患者,按检查方法分为对照组和观察组。对照组常规扫描确定放疗靶区,观察组DWI确定放疗靶区。测量颈部小淋巴结转移瘤、大淋巴结转移瘤和良性淋巴结ADC值,绘制受试者工作特征（ROC）曲线,确定诊断NPC颈部小淋巴结转移瘤的ADC诊断阈值和效能。比较两组放疗靶区勾画面积 ...

H19、CHI3L1在发生侧颈淋巴结转移的甲状腺乳头状癌中的表达研究
Zhongguo shiyan zhenduanxue, 2023 目的 以发生侧颈淋巴结转移的甲状腺乳头状癌(PTC)为研讨对象，旨在找到阻断淋巴管形成、降低侧颈淋巴结转移率的方法。方法 长链非编码RNA(lncRNA)测序得出，在发生侧颈淋巴结转移的PTC中存在差异表达基因，筛选明显上调、下调的基因。结果 发生侧颈淋巴结转移的PTC中有4782个上调lncRNA,3807个下调lncRNA。结论 lncRNA H19、lncRNA CHI3L1出现明显表达差异，推测与发生侧颈淋巴结转移有关，可作为靶点构建lncRNA-X敲除慢病毒，验证是否与淋巴管形成有关。
