目的 探讨超声弹性成像联合高频超声在甲状腺乳头状癌诊断中的应用价值。方法 2022年1月—2023年6月选择在中国人民解放军联勤保障部队第九九〇医院诊治的疑似甲状腺乳头状癌患者82例,所有患者均给予超声弹性成像联合高频超声检查,记录超声特征。所有患者均行病理检查,并以病理检查作为判断的金标准。结果 在82例患者中,病理诊断为甲状腺乳头状癌48例（癌性组）,占比58.54%;甲状腺良性结节34例（良性组）,占比41.46%。癌性组的形态异常、后方回声衰减、钙化、晕环征、边界不清晰、内部低回声等超声征象占比为81.25%、83.33%、83.33%、83.33%、81.25%、81.25%,高于良性组的52.94%、47.06%、47.06%、41.18%、47.06%、52.94%（P<0.05）。癌性组的收缩期最高流速低于良性组（P<0.05）,阻力指数、搏动指数与良性组相比有提高（P<0.05）。癌性组的弹性成像评分多为3~4分,良性组多为2分,两组比较差异有统计学意义（P<0.05）。超声弹性成像联合高频超声判断为甲状腺乳头状癌47例,诊断中的灵敏度与特异度分别为97.92%（47/48）和100.00%（34/34）。结论 甲状腺乳头状癌在超声上多表现为血流信号异常、钙化、后方回声衰减、晕环征等特征,超声弹性成像评分多为3~4分,超声弹性成像联合高频超声在其诊断中具有较高的应用价值。

Objective To explore the application value of ultrasound elastography combined with high-frequency ultrasound in the diagnosis of papillary thyroid cancer（PTC）．Methods From January 2022 to June 2023,82 patients with suspected PTC were treated at Chinese People’s Liberation Army Joint Logistics Force 990 Hospital．All patients were given ultrasound elastography combined with high-frequency ultrasound examination to record ultrasound features．All cases were given pathological examination,and the pathological examination were used as the gold standard for diagnosis．Results Among the 82 patients,48 were PTC（cancerous group）,accounting for 58.54%;and the other 34 were benign thyroid nodules（benign group）,accounting for 41.46%．The proportion of morphological abnormalities,posterior echo attenuation,calcification,halo ring signs,unclear boundary and internal hypoechoics in cancerous group were 81.25%,83.33%,83.33%,83.33%,81.25% and 81.25%,which were significantly higher than 52.94%,47.06%,47.06%,41.18%,47.06% and 52.94% in the benign group（P<0.05）．The highest systolic flow velocity in the cancerous group was significantly less than that in the benign group（P<0.05）,and the resistance index and pulse index were also significantly higher compared with the benign group（P<0.05）．The elastography score were mostly 3~4 in the cancerous group and 2 in the benign group,with a significant difference between the two groups（P<0.05）．Forty-seven cases of PTC were diagnosed by ultrasound elastography combined with high frequency ultrasonography,and the sensitivity and specificity in diagnosis were 97.92%（47/48）and 100.00%（34/34）,respectively．Conclusions PTC is often characterized by abnormal blood flow signals,calcification,posterior echo attenuation,halo sign and so on．The ultrasound elastography score is usually 3~4 points．Ultrasonic elastography combined with high frequency ultrasound has high value in diagnosis of PTC．

目的 探讨甲状腺乳头状癌患者在严重短期甲减的状态下甲状腺功能及相关因素对血脂水平的影响。方法 纳入61例通过病理确诊为甲状腺乳头状癌的患者,采集所有患者在手术前与碘治疗前的甲状腺功能水平与血脂水平等资料,比较患者不同性别、年龄、术式、淋巴结转移情况等相关因素对血脂的影响。结果 碘治疗前的全部血脂指标均高于手术前的基线水平;在促甲状腺激素 (TSH)>60 mIU/L组中的总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、载脂蛋白A1(APO-A1)、载脂蛋白B(APO-B)、脂蛋白(LP)水平明显高于TSH≤60 mIU/L组;女性患者的甘油三酯(TG)、动脉硬化指数(AI)水平明显低于男性患者,男性组的HDL-C、APO-A1水平低于女性组,年龄>45岁的患者TC水平高于年龄≤45岁的患者,差异均有统计学意义(P均＜0.05);不同术式及淋巴结转移分组间的血脂水平未见明显差异(P＞0.05);TC水平与游离三碘甲状原氨酸(FT3)、游离甲状腺素(FT4)、甲状腺素(T4)水平呈负相关(r分别为-0.342、-0.370、-0.340),HDL-C、LDL-C及APO-B水平与T4水平呈负相关(r分别为-0.294、-0.354、-0.324),APO-A1水平与FT4、三碘甲状腺原氨酸(T3)、T4水平呈负相关(r分别为-0.306、-0.262、-0.263),LPa水平与T3、T4水平呈负相关(r分别为-0.268、-0.313)。结论 甲状腺乳头状癌碘治疗前短期甲减可以导致全套血脂指标升高,在此甲减状态下程度越严重的甲减可产生越高的血脂水平,同时男性患者与中老年患者也可伴随更高的血脂水平。

Objectives To investigate the influence of thyroid function and related factors on blood lipid levels in patients with papillary thyroid cancer under short-term severe hypothyroidism. Methods Sixty-one patients with papillary thyroid carcinoma diagnosed by pathology were included. The data of thyroid function and blood lipid levels of all patients before operation and iodine treatment were collected. The effects of gender, age, operation mode, lymph node metastasis and other related factors on blood lipid were compared. Results Before iodine treatment, all blood lipid indexes were higher than the baseline level before operation. The levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (APO-A1), apolipoprotein B (APO-B), lipoproteins (LP) in the thyroid stimulating hormone (TSH)>60 mIU/L group were significantly higher than those in the TSH≤60 mIU/L group.Triglyceride (TG) and arteriosclerosis index (AI) levels were significantly lower in female patients compared with male patients, HDL-C and APO-A1 levels were lower in male patients compared with female patients, and TC levels were higher in patients aged>45 compared with those aged≤45, with significant differences (all P<0.05). No significant differences were observed in lipid levels among the different surgical procedures and lymph node metastasis subgroups (P>0.05). TC levels were negatively correlated with free triiodothyronines (FT3), free thyroxine (FT4), thyroxine (T4) levels (r=-0.342,-0.370,-0.340,respectively). HDL-C, LDL-C, and APO-B levels were negatively correlated with T4 levels (r=-0.294, -0.354, -0.324,respectively), APO-A1 levels were negatively correlated with FT4, triiodothyronine (T3), T4 levels (r=-0.306,-0.262,-0.263,respectively), and LP levels were negatively correlated with T3 and T4 levels (r=-0.268,-0.313, respectively). Conclusions Short term hypothyroidism before iodine treatment for papillary thyroid cancer could lead to the increase of full set of blood lipid indexes, male patients and middle-aged and elderly patients could also be accompanied by higher blood lipid levels.

目的 探讨I¹³¹联合促甲状腺激素(TSH)抑制治疗对术后中高危组甲状腺乳头状癌(PTC)患者心肌纤维化及心房颤动(AF)的影响。方法 选取2016年8月—2017年8月南华大学附属第一医院收治的因PTC行甲状腺双侧腺叶全切术或近全切除术患者69例,根据复发危险度分层分为中危组(49例)和高危组(20例), 两组患者均行I¹³¹ 联合TSH抑制治疗,治疗后嘱患者3个月进行1次复诊或自觉不适及时复诊,观察患者心血管系统症状、心房颤动及心肌纤维化发生情况,患者治疗前后可溶性基质溶素-2(sST2)、生长分化因子-15(GDF-15)、半乳糖凝集素-3 (GAL-3)及血清乳酸脱氢酶(LDHA)含量变化。结果 I¹³¹联合TSH抑制治疗后患者心房颤动发生率和心肌纤维化相关指标水平明显高于治疗前,且高危组患者治疗后心房颤动发生率和心肌纤维化相关指标水平高于中危组,差异均有统计学意义(P<0.05)。结论 I¹³¹联合TSH抑制治疗会增加PTC患者心肌纤维化和心房颤动的发生概率,且高危组PTC患者心肌纤维化和房颤的发生率高于中危组。

Objective To investigate the impact of I¹³¹ combined with thyroid-stimulating hormone(TSH) for suppressive treatment on myocardial fibrosis(MF) and atrial fibrillation(AF) in patients with papillary thyroid (PTC). Methods 69 patients with PTC undergoing total or subtotal thyroidectomy admitted into First Affiliated Hospital of University of South China from Aug. 2016 to Aug. 2017 were selected and divided into middle-risk group (49 cases) and high-risk group (20 cases) according to the recurrence risk stratification. Two groups of patients were given I¹³¹ combined with thyroid-stimulating hormone for suppressive treatment. The patients were instructed to undergo a follow-up visit every 3 months after treatment or whenever felt unwell. The incidences of cardiovascular system symptoms, atrial fibrillation and myocardial fibrosis, changes of contents of serum soluble ST2 (sST2), growth differentiation factor-15 (GDF-15), galectin-3 (GAL-3) and lactate dehydrogenase A (LDHA) were observed. Results After I¹³¹ combined with thyroid-stimulating hormone suppressive treatment, the incidences of atrial fibrillation and myocardial fibrosis after treatment were higher than that before treatment, and the incidences of atrial fibrillation and myocardial fibrosis of high-risk group were higher than those of the middle-risk group, with statistically significant differences (P＜0.05). Conclusion Combined use of I¹³¹ and thyroid-stimulating hormone for suppressive treatment can increase the incidences of atrial fibrillation and ventricular remodeling of patients with PTC, and the incidences of high-risk group were higher than those of the middle-risk group.

Objective To follow-up 186 cases of papillary thyroid microcarcinoma and analyse their tumor recurrence rate、survival rate and complicationg after 5 and 10 years postoperation, to investigate prognosis of papillary thyroid microcarcinoma from different operation approaches. Methods 186 cases of papillary thyroid microcarcinoma were from 1993 to 2003. All the patients were divided into two groups,102 cases(group Ⅰ) performed with resection of the majority of thyroid gland, and 84 caces(group Ⅱ) performed with total thyroidectomy, thyroidectomy+isthmus thyroidectomy+contralateral thyroid lobectomy+central lymph node ablation. Results The recurrence and survival rates after 5 and 10 years were not significantly different between the two groups, but compared group Ⅰ, the incidences of hypocalcemia and hypothyroidism were higher in group Ⅱ(P<0.05). Conclusion Papillary thyroid microcarcinoma had better prognosis. Resection of the majority of thyroid gland treating papillary thyroid microcarcinoma is safe and feasible.
