原发癌灶定位与甲状腺微小癌颈侧区淋巴结转移关系研究

目的 探究原发灶定位与甲状腺乳头状微小癌（PTMC）颈侧区淋巴结转移的关系，评估超声检查预测颈侧区淋巴结转移的准确率。方法 回顾性分析2014年1月至2015年12月天津医科大学肿瘤医院收治的134例PTMC病人的临床资料，均行中央区淋巴结清扫+改良颈侧区淋巴结清扫。依据超声定位分组，分析癌灶位置与颈侧区淋巴结转移的关系。结果 颈侧各分区淋巴结转移发生率分别为：Ⅱ区30.6%、Ⅲ区50.7%、Ⅳ区57.5%、Ⅴ区11.3%。癌灶位于中上极者颈侧区淋巴结转移发生率高于癌灶位于下极者（89.7% vs. 75.7%，P=0.038），靠近外侧者较内侧者更易出现颈侧区淋巴结转移（93.7% vs. 81.4%，P=0.049）。超声检查判定Ⅱ、Ⅲ、Ⅳ、Ⅴ区淋巴结转移的敏感度分别为43.9%、85.3%、85.7%、14.3%；特异度为91.4%、57.6%、35.1%、99.1%。超声预测Ⅲ、Ⅳ区淋巴结转移敏感度较高，Ⅱ、Ⅴ区淋巴结转移特异度较高。结论 癌灶位置与甲状腺微小癌颈侧区淋巴结转移密切相关，超声可为临床确定颈侧区淋巴结的清扫范围提供依据。

甲状腺癌根治术中不同途径显露喉返神经的应用效果评价

目的 探讨甲状腺癌根治术中不同途径显露喉返神经的应用情况.方法 根据随机数字表法将92例进行甲状腺癌根治术的患者随机分为对照组和观察组,每组46例.对照组采用甲状腺下动脉途径法显露喉返神经,观察组采用甲状腺最下动脉途径法显露喉返神经.比较两组患者寻找喉返神经的时间、术中出血量、手术时间、术后声音嘶哑和喉返神经损伤的发生率.结果 观察组患者寻找喉返神经的时间和手术时间均明显短于对照组患者,差异均有统计学意义(P﹤0.01).观察组患者的术中出血量明显少于对照组患者,差异有统计学意义(P﹤0.01).观察组患者术后声音嘶哑和喉返神经损伤的发生率均低于对照组患者,差异均有统计学意义(P﹤0.05).结论 甲状腺癌根治术中应用不同途径显露喉返神经,其效果存在差异.与甲状腺下动脉途径法相比,甲状腺最下动脉途径法能够明显缩短寻找喉返神经的时间和手术时间,减少术中出血量,降低术后声音嘶哑和喉返神经损伤的发生率,值得临床推广应用.     

甲状腺乳头状癌预后因素的研究进展

甲状腺癌是最常见的内分泌系统恶性肿瘤,近年来发病率迅速上升,其中以甲状腺乳头状癌最为多见.尽管甲状腺乳头状癌患者的肿瘤特异性死亡率较低,但仍有部分患者可出现复发甚至远处转移,严重影响患者的生活质量.包括临床特征和分子特征在内的多种因素可影响甲状腺乳头状癌患者的预后,本文综合相关研究,对甲状腺乳头状癌患者的预后因素进行综述,以便于临床评估患者的预后,并根据患者的个体情况制订合理的治疗方案及临床管理策略.     

经鼻高流量氧气湿化治疗老年慢性阻塞性肺疾病急性加重合并呼吸衰竭的可行性研究

ObjectiveTo investigate the feasibility of transnasal heated humidified high flow nasal cannula oxygen therapy (HFNC) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with respiratory failure in elderly patients. MethodsA total of 176 elderly patients with AECOPD complicated with respiratory failure who were hospitalized at Peking University Shougang Hospital from December 2016 to January 2022 were enrolled, including 82 patients in an HFNC group and 94 patients in an NPPV group. After treatment, pulse oxygen saturation (SPO₂), arterial partial pressure of carbon dioxide (PaCO₂), oxygenation index (OI), respiratory rate (RR), heart rate (HR), mean arterial pressure (MAP), comfort score, discharge rate, rate of endotracheal intubation, rate of transfer to intensive care unit (ICU), and mortality were compared between the two groups. The independent sample t-test was used for comparison between the two groups. Statistical data are expressed in percentage or number of cases and the χ² test was used for their comparisons. ResultsThe SPO₂ values at 30 min, 1 h, and 6 h were significantly higher in the HFNC group than in the NPPV group (t=-2.049,-2.618, and -3.314, P=0.043, 0.010, and 0.001, respectively). SPO₂ before discharge was significantly lower than that of the NPPV group (t=2.162, P=0.033), but OI at each time point and before discharge had no statistical significance (P＞0.05). MAP at 6 h was significantly higher in the HFNC group than in the NPPV group (t=-2.209, P=0.029), but within the normal range. HRs at 2 h and 3 h in the HFNC group were significantly higher than those of the NPPV group (t=-2.199 and -2.336, P=0.030 and 0.021, respectively). There were no significant differences in RR, HR, or MAP between the two groups at other time points and before discharge (P＞0.05). There was no significant difference in PaCO2 between the two groups (P＞0.05). Comfort score in the HFNC group was significantly higher than that of the NPPV group (t=-46.807, P＜0.001). There were no significant differences in discharge rate, ICU transfer rate, endotracheal intubation rate, and mortality between the two groups (P＞0.05). ConclusionHFNC is as effective as NPPV in treating elderly patients with AECOPD complicated with type Ⅰ or mild type Ⅱ respiratory failure, and HFNC is more comfortable than NPPV.     

数显角度仪在CT引导经皮肺穿刺活检中的应用

  目的  CT引导经皮肺穿刺活检对于肺小结节以及临近大血管的病灶具有难度。本研究旨在探讨数显角度仪在CT引导经皮肺穿刺活检中的应用价值。  方法  回顾性分析2018年1月至2018年9月南华大学附属第一医院经皮肺穿刺活检的35例患者。将患者分为A、B、C3组，A组与B组为病灶直径≤30 mm的肺结节，其中A组接受数显角度仪协助下的CT引导经皮肺穿刺活检，B组则在CT引导下徒手操作经皮肺穿刺活检。C组为病灶直径 > 30 mm肺部肿块，在CT引导下徒手操作经皮肺穿刺活检。然后比较3组之间穿刺前的肿块大小、进针次数、进针距离及术后血气胸并发症的差异。  结果  A组肺结节最大直径为（18.4±2.1）mm，显著小于B组（28.3±2.0）mm及C组（43.3±3.6）mm（P=0.003与P=0.003）。A组部分患者合并严重慢性阻塞性肺疾病（chronic obstructive pulmonary diseases，COPD）及病灶邻近大血管，且该组穿刺点至胸壁外侧距离也明显高于B组（P=0.039）。但A组一次性穿刺成功概率为100%，明显高于B、C组，同时该组术后并发症亦明显少于另外两组。  结论  经数显角度仪协助的CT引导下经皮肺穿刺活检术为一项安全、简便、准确的诊断方法，特别在肺小结节病变的患者中具有较好的应用价值。
