【Abstract】Objective To study the relation between iodine and experimental autoimmune thyroiditis(EAT). Methods Establishment of animal model was performed with iodine and thyroglobulin(TG).The rats were randomly divided into 5 groups: normal control group(NC), low iodine group (LI,500 μg/L), high iodine group(HI,500 mg/L), TG+Freund adjuvant group(TG) and TG+Freund adjuvant+HI group(TG+HI). The rats in TG group and TG+HI group were rejected hypodermically with TG emulsified by complete Freund adjuvant, and strengthen immunity was conducted with TG emulsified by incomplete Freund adjuvant on 15 days. After that, strengthen immunity was done weekly till the end of the experiment. Serum TGAb and TPOAb were measured by radioimmunoassay. Observation of the pathological changes of thyroid gland was also done. Results Thyroid follicular destruction and lymphocytic infiltration in the TG+HI group (3.83±1.72) and HI group (3.00±0.89) were significantly higher than that of the NC group(0.67±0.82)，P＜0.05. The results of the TG group were higher compared with the NC group, but there were no significant differences between them（Pgt;0.05）. The levels of TGAb in the TG+HI (4.990±1.505)，HI (3.589±1.240) and TG group (4.883±1.198) were significant higher than those of the NC group (0.642±0.454) and the LI group (0.707±0.240)，P＜0.01. The levels of TPOAb in TG+HI group (1.475±0.523) and TG group (1.316±0.606) were significantly higher than those of the NC group (0.365±0.196) and the LI group（P＜0.01）. Serum TGAb and TPOAb levels were positively correlated with the histological grades of lymphocytic thyroiditis(r=0.9,P＜0.05）. Conclusion Excessive iodine intake may induce the occurrence of EAT. The induction of EAT with excessive iodine and TG may be more efficient.

Methods : Analyze the clinical data of 77 children with Chronic lymphocytic thyroiditis. Results : The proportion of men to women was 1:67 in all 77 children, and the mean age at diagnosis was 1021±233(age range 5~15 years). The percentage of positive TGAb and TPOAb were 94% and 96%, respectively in all the 77 children. One children was diagnosed Chronic lymphocytic thyroiditis coexistent with thyroid papillary carcinoma by FNAB. There were 37 children had hypothyrodism in all the 77 after 1～39 months. Conclusion : CLT is more frequent in females, and at the time of diagnosis more children and adolescents had hypethyrodism than adults. TGAb and TPOAb are important markers for the diagnosis of CLT. The percentage of children had hypothyrodism is increasing along with the course of disease.
Objective To summarize research status of correlation of chronic lymphocytic thyroiditis (CLT) and papillary thyroid carcinoma (PTC), in order to provide a basis for early diagnosis, prognosis, and prevention of PTC. Method The literatures about the recent studies of the correlation of the CLT and PTC were reviewed according to the results searched from PubMed database, SpringerLink database, Web of Science database, Wanfang database, CNKI database, and VIP database. Results The most of patients with CLT combined with PTC are young women, the characteristics are multifocal and occult, the prognosis is good. Its genesis might be related to the ionizing radiation, iodine intake, endocrine disorders, immune disorders, molecular biology, and other factors. But there are still different controversies about its specific pathogenesis and surgical treatment. Conclusions CLT is closely related to PTC. However, relationship between CLT combined with PTC and changing regularity of molecular biology, pathogenesis, or prognosis needs further to be studied and followed-up for a longer-term.
ObjectivesTo systematically review the efficacy of Bailing capsule for autoimmune antibodies in Hashimoto thyroiditis (HT).MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases were electronically searched to collect the randomized controlled trials (RCTs) on Bailing capsule in treatment of HT from inception to January 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs involving 428 patients were included. The results of meta-analysis showed that the changes of TGAb and TPOAb in Bailing capsule combined with Euthyrox group were higher than that in control group (MD=−228.91, 95%CI −398.61 to −59.20, P=0.008; MD=−158.19, 95%CI −222.44 to −93.94, P<0.000 01); the changes of TGAb and TPOAb in Bailing capsule combined with Iodine modification diet group were higher than that in control group(MD=−499.27, 95%CI −540.39 to −458.15, P<0.000 01; MD=−407.37, 95%CI −448.60 to −366.14, P<0.000 01).ConclusionsCurrent evidence shows that Bailing capsule combined with other therapies can decrease the levels of TGAb and TPOAb in HT patients. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
ObjectiveTo summarize and analyze the clinical characteristics of patients with thyroiditis who would be misdiagnosed with thyroid tumor easily. MethodThe clinical data of 19 patients with thyroiditis who were misdiag-nosed with thyroid tumor in our department from 2009 to 2012 were analyzed retrospectively. ResultsAll of 19 patients underwent surgery, among which 8 cases were diagnosed with chronic lymphocytic thyroiditis after operation, 10 cases diagnosed with subacute thyroiditis, and 1 case diagnosed with suppurative thyroiditis.Different surgery program such as the biopsy or wedge resection was adopted to the subacute thyroiditis and the chronic lymphocytic thyroiditis respec-tively. ConclusionSometimes, it is very difficult to distinguish atypical thyroiditis from thyroid tumor so that we must pay attention to the patients who had nontumorous characteristics in order to decrease the misdiagnosis.
目的 探讨慢性甲状腺炎合并亚急性甲状腺炎患者的临床特征，明确其诊断方法，以减少临床误诊率。方法 回顾性分析2008年6月至2009年12月期间吉林大学中日联谊医院甲状腺外科行手术治疗的5例慢性甲状腺炎合并亚急性甲状腺炎患者的临床资料，包括病史、症状、体征、临床诊治过程、临床辅助检查结果（甲状腺功能检查、彩色多普勒超声检查、核素扫描等）的特点及病理特征。结果 5例患者中仅1例患者术前伴有间断发热和颈部疼痛病史，另外4例患者均无甲状腺炎的典型临床表现。5例患者临床诊治过程较长，病程迁延，平均病程6.8个月，药物对症治疗效果欠佳，症状及彩色多普勒超声检查结果无明显改善，均因术前不能除外恶变情况而行手术治疗。术中及术后病理检查结果均证实为慢性甲状腺炎合并亚急性甲状腺炎。结论 慢性甲状腺炎合并亚急性甲状腺炎临床诊断较困难，病程迁延，易被误诊，必要时可行穿刺病理学检查以明确诊断。
Objective To compare differences of characteristics of ultrasonic elasticity imaging for benign and malignant small thyroid nodules with or without Hashimoto thyroiditis (HT). Methods The thyroid nodules with ≤1 cm size and the category 4A, 4B, 4C, and 5 of Thyroid Imaging Reporting and Data System (TI-RADS) were included into this study, and a further examination of real-time elastography was performed. The final diagnosis was relied on the pathological diagnosis. The elasticity score and strain ratio (SR) were recorded and compared between these two groups, respectively. Results Of the 424 nodules, 103 nodules were accompanied with HT (thyroid nodule with HT group), 321 nodules were not accompanied with HT (thyroid nodule without HT group). In the thyroid nodule with HT group, the area under the receiver operator characteristic (ROC) curve (AUCs) of the elasticity score and the SR was 0.685 and 0.676, respectively; the optimal cut offs of the elasticity score and the SR was 3 points and 2.45 respectively, their corresponding sensitivity, specificity, and accuracy was 75.7%, 57.6%, 68.0% and 75.7%, 60.6%, 67.6%, respectively. In the thyroid nodule without HT group, the AUCs of the elasticity score and the SR was 0.692 and 0.692, respectively; the optimal cut offs of the elasticity score and the SR was 4 points and 2.84, respectively; their corresponding sensitivity, specificity, and accuracy was 57.5%, 74.2%, 69.2% and 76.1%, 59.7%, 67.7%, respectively. Conclusions Elastography is helpful in differential diagnosis of benign and malignant small thyroid nodules. While, standards of elasticity score and SR value in differential diagnosis are different between benign and malignant small thyroid nodules with HT and without HT, elasticity score and SR ratio decrease in benign and malignant small thyroid nodules with HT.
