ABSTRACT
Objective To investigate the correlation between uterine globulin associated protein 1(UGRP1)and Fas mediated apoptosis pathway in hashimoto thyroiditis(HT).Methods The expression of UGRP1 in thyroid cells of normal people and HT patients was detected by immunohistochemistry(IHC).FRTL-5 cells were transfect-ed by plasmids in vitro,and control group,UGRP1 group,Fas group were established respectively.Real-time fluo-rescent quantitative reverse transcription PCR(RT-qPCR)was used to detect the expression of Fas and UGRP1 mRNA in each group.Results UGRP1 expression was positive in thyroid cells of HT patients and negative in that of normal people.There were no significant differences between control group and UGRP1 group in Fas gene ex-pression(1.085 0±0.124 9 vs 1.021 0±0.113 9).Compared with the control group,the expression of UGRP1 gene increased significantly in Fas group(P＜0.000 1,5.807 0±0.323 2 vs 0.752 7±0.076 0).Conclusion The high expression of UGRP1 in HT may be related to apoptosis pathway mediated by Fas.
ABSTRACT
Objective:To analyze and compare the pathological data characteristics of patients with simple papillary thyroid carcinoma (PTC) and PTC combined with Hashimoto’s thyroiditis (HT), so as to provide clinical treatment ideas.Methods:A retrospective analysis was performed on the medical records of 326 PTC patients who met the requirements and underwent surgical treatment in the Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine from Jan. 2020 to May. 2022. There were 81 males and 245 females. They were divided into PTC group and HT-PTC group, according to whether they were combined with HT. Clinical data were collected and organized. The collection indicators included patient gender, age, body mass index (BMI), five preoperative thyroid function items including free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), BRAF gene mutation, single or bilateral lesions, single or multiple lesions, largest postoperative pathological tumor lesions diameter, cervical lymph node metastasis (LNM) status, etc. At the same time, all patients were divided into CLNM group and no CLNM group according to CLNM status. The two groups were compared in terms of gender, age ≥55 years old, whether combined with HT, number of lesions, unilateral and bilateral, extraglandular invasion, microcarcinoma, and BRAF gene. Statistical software was used to analyze the results. t test, χ2 test, and logistic regression analysis were adopted. P<0.05 indicates that the difference is statistically significant. Results:The proportion of female patients in both groups was higher, and the proportion of female patients in the HT-PTC group (90/100, 90%) was higher than that in the PTC group (155/226, 69.59%). HT-PTC patients were younger than patients in the PTC group (43.03±12.72 vs. 43.70±12.63) years old, and their TSH (2.71±1.69 vs. 2.02±1.46) uIU/mL was higher. The differences were statistically significant (all P<0.05). There were no statistically significant differences in BMI, FT3, FT4, T3, or T4 (all P>0.05). The HT-PTC group had a lower proportion of BRAF gene mutations [87/100 (87%) vs. 212/226 (93.8%) ], a smaller maximum tumor diameter (1.06±0.73 vs. 1.32±0.97 cm), and a lower proportion of CLNM [37 /100 (37%) vs. 118/226 (52.2%) ]. The number of LNMs with metastasis is less (3.33±2.21 vs. 4.76±4.00), and it was more likely to be multifocal [44/100 (44%) vs. 73/226 (32.74%) ]. All differences were statistically significant (all P<0.05), and the differences in bilateral gland lobes involvement and extra-glandular invasion were not statistically significant. When accompanied by CLNM, gender (male vs. female) [55/100 (35.45%/64.52%) vs. 26/145 (15.2%/84.85%) ], age ≥ 55 years (yes vs. no) [21/134 (13.55) %/86.45%) vs. 50/121 (29.24%/70.76%) ], HT (yes vs. no) [37/118 (23.87%/76.13%) vs. 63/108 (36.84%/63.16%), number of lesions (single focus vs. multiple focus) [90/65 (41.94%/50.06%) vs. 119/52 (69.59%/30.41%) ], microcarcinoma (yes vs. no) [83/72 (53.55%/45.45%) vs. 139/32 (81.29%/18.71%) ] and extraglandular invasion (with vs. without) [38/117 (24.52%/75.48%) vs. 27/144 (17.42%/84.21%) ] had statistics significance (both P<0.05). There was no statistical significance in bilateral lesion involvement or BRAF gene mutation (all P>0.05). Multivariate logistic regression analysis showed that age, microcarcinoma, HT, gender, and number of lesions were independent risk factors for CLNM, and male gender and multifocal cancer were risk factors for CLNM. Age ≥55 years, microcarcinoma, and combined HT were negatively associated with CLNM. Conclusions:HT may promote the occurrence of PTC, but can inhibit its development. In the short term, patients with HT can have a better prognosis than those with simple PTC.
ABSTRACT
Objective·To investigate the effect of Astragali Radix on T lymphocyte subsets and cytokine expression in Hashimoto's thyroiditis patients with normal thyroid function.Methods·A total of 120 Hashimoto's thyroiditis patients with normal thyroid function and complete data were selected from January 2020 to December 2020 in Jinshan Branch of Shanghai Sixth People's Hospital.The patients were randomly divided into intervention group(n=60)and control group(n=60)by the method of random number table.The treatment plan of the control group was iodine appropriate state diet,and the intervention group was combined with oral Astragali Radix solution(150 mL per time,twice/d)on the basis of the treatment of the control group.The two groups were treated for 6 months.The changes in peripheral blood serum T lymphocyte subsets(CD3+,CD4+,CD8+,and CD4+/CD8+),cytokines[interleukin-2(IL-2),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-10(IL-10)],hypersensitive C-reactive protein(hs-CRP),erythrocyte sedimentation rate(ESR),thyroid function,autoantibody,liver and kidney function,and other biochemical indexes were compared before and after treatment between the two groups.Adverse reactions were observed during the treatment.The factors influencing the change amplitude of thyroid peroxidase antibody(TPOAb)were analyzed by multifactor linear regression.Results·Finally,118 patients,with 59 cases in each group,were included in the study.After 6 months of treatment,the intervention group showed significant improvements in the proportions of CD4+ T cells,the ratio of CD4+/CD8+,and the levels of IL-2,TNF-α,IL-10,hs-CRP,ESR,TPOAb,and thyroglobulin antibody(TGAb)compared to the values before treatment and in the control group(P<0.05).There were no statistically significant differences on the above indicators before and after treatment in the control group(P>0.05).No serious adverse reactions were observed in the intervention group.Multiple linear regression analysis results showed that the use of Astragali Radix,increase of CD4+ level,increase of CD4+/CD8+ ratio,and decrease of hs-CRP level were influencing factors for the decrease of TPOAb level(β=-0.393,P=0.029;β=-0.513,P=0.010;β=-0.351,P= 0.035;β=0.434,P=0.023).Conclusion·Astragali Radix can improve the levels of CD4+ T cells,CD4+/CD8+ratio,IL-2,TNF-α,IL-6,and IL-10 in Hashimoto's thyroiditis patients with normal thyroid function,and it is safe to use.
ABSTRACT
Objective To investigate the diagnostic value of the T2WI gray scale ratio for Hashimoto's thyroiditis(HT).Methods The T2WI-iterative decomposition of water and fat with echo asymmetry and least square estimation(IDEAL)quantitation sequence water images of 22 HT cases were analyzed retrospectively.The gray scale ratio of the thyroid,sternocleidomastoid muscle,trachea cavity,and subcutaneous fat at the same layer were measured on the picture archiving and communication systems(PACS).The gray scale ratios of thyroid/sternocleidomastoid muscle(T/M),thyroid/trachea cavity(T/Tr),and thyroid/lipid(T/L)were calculated.The intraclass correlation coefficient(ICC)was used to evaluate the consistency among the measurements,and the optimal threshold for distinguishing HT from non-HT was determined via the receiver operating characteristic(ROC)curve.The Spearman correlation analysis was used to analyze the correlation between T/M,T/Tr,T/L ratios,and titers of thyroid peroxidase antibody(TPO-Ab)and thyroglobulin antibody(Tg-Ab),respectively.Results On the T2WI-IDEAL quantitation sequence water images,the(x)±s of T/M,T/Tr,T/L ratios for HT and non-HT were 2.17±0.47 and 1.62±0.21(t=14.90,P<0.001),9.40±3.24 and 4.87±2.93(t=11.42,P<0.001),1.66±0.32 and 1.21±0.31(t=7.51,P<0.001),respectively.The area under the curve(AUC)of T/M,T/Tr,and T/L ratios for diagnosing HT were 0.89,0.86,and 0.85,respectively;the optimal thresholds were 1.90,3.50,and 1.36,and the sensitivity and specificity were 72.7%and 100%,100%and 40.5%,95.5%and 29.7%,respectively.The T/M ratio had a moderate correlation with TPO-Ab(r=0.513,P<0.05),and T/Tr,T/L ratios had a mild correlation with TPO-Ab,respectively.Conclusion The T/M ratio in the T2WI gray scale ratio can quantitatively and objectively distinguish HT from non-HT to some extent and is correlated with TPO-Ab.It has extremely high specificity and holds promise as a non-invasive imaging method for the diagnosis of incidental HT.
ABSTRACT
Objective To investigate the factors affecting the number of lymph nodes obtained by unilateral lobectomy and isthmus combined with prophylactic ipsilateral central lymph node dissection for papillary thyroid cancer,and to analyze the pattern of change so as to provide an important basis for clinical treatment of papillary thyroid cancer.Methods Retrospective analysis was performed on the clinical and pathological data of 193 patients admitted to the department of Thyroid Surgery of the First Affiliated Hospital of Jinzhou Medical University from January 2019 to January 2022 for papillary thyroid cancer who underwent unilateral glandular lobe and isthmus resec-tion combined with prophylactic ipsilateral central lymph node dissection.The number of obtained lymph nodes was divided into a group with high number of obtained lymph nodes(n>6)and a group with low number of obtained lymph nodes(n≤6).Univariate analysis and multivariate analysis were used to explore the factors affecting the num-ber of obtained lymph nodes.The influence of the number of lymph nodes on the central lymph node metastasis was evaluated by correlation analysis,and the influence of the number of lymph nodes on the quality of life of patients by postoperative complications analysis.Results The number of lymph nodes obtained was positively correlated with the number of lymph node metastases in the central region(r = 0.240,P<0.05)and the rate of lymph node metastasis(r = 0.161,P<0.05),respectively.The number of lymph node metastases controlled remained unchanged,and the rate of lymph node metastasis decreased with the increase of the number of obtained lymph nodes(r =-0.444,P<0.05).Univariate analysis of the number of lymph nodes between the two groups showed no significant differences in terms of sex,age,operation duration,BMI,maximum tumor diameter,multifocality,Hashimoto's thyroiditis,focal location,capsular invasion,contralateral thyroid nodule,parathyroid transplantation and BRAF gene V600E mutation(P>0.05).There was statistical significance in the application of nano carbon between the two groups(P<0.05).Logistic binary regression analysis showed that the combination of Hashimoto's thyroiditis and the application of carbon nanoparticles were independent influencing factors for the high number of lymph nodes obtained(P<0.05).ROC curve analysis suggested that the area under the curve occupied by carbon nanoscale was 0.658(95%CI:0.580～0.735,P<0.05),and the area under the curve occupied by Hashimoto's thyroiditis was 0.584(95%CI:0.504～0.665,P<0.05).In addition,there was no significant difference in the incidence of vocal cord paralysis and lymphatic leakage between the two groups(P>0.05).Conclusions When the number of lymph nodes in the cen-tral region remained unchanged,the higher the number of lymph nodes obtained,the lower the rate of lymph node metastasis.The application of nano-carbon and patients with Hashimoto's thyroiditis could increase the number of lymph nodes obtained,and there is no significant difference in the incidence of postoperative complications between high and low number of lymph nodes obtained.
ABSTRACT
Objective To investigate the therapeutic effect of cholesterol sulfate(CS)on the Hashimoto's thyroiditis mouse model.Methods Female NOD.H-2h4 mice were fed with 0.05％NaI in different periods and treated with CS by intraperitoneal injection for two consecutive weeks.HE staining was used to visualize and score the degree of lymphocyte infiltration in the thyroid;serum levels of thyroglobulin antibody(TgAb),thyroid peroxidase antibody(TPOAb),thyroxine(T4),and thyroid stimulating hormone(TSH)were detected by ELISA.The proportions of B cells and Treg,Th17,Th1,and Th2 cells were analyzed by immunofluorescence staining flow cytometry.Results HE staining showed that the inflammatory score of thyroid tissue in mice after intraperitoneal injection of CS in the 8-week group and the 16-week group decreased significantly(P＜0.05).In the 64-week group,there was no significant difference between the treatment group and the induction group(P=0.31).Serological analysis showed that after CS intervention,the levels of TgAb and TPOAb in mice induced by 0.05％NaI significantly lowered(P＜0.05)in the 8-week group and the 16-week group,while thyroid function(TSH and T4 levels)of the mice changed significantly only in the 16-week group.Flow cytometry analysis showed that in the 8-week group,after CS intervention the proportions of B lymphocytes and Th1,Th2,Th17 and Treg cells in mice were significantly changed(P＜0.05).Conclusion CS has significant therapeutic and remission effects on the early and middle stages of Hashimoto's thyroiditis.

ABSTRACT
Objective:To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole.Methods:A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by xˉ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M( Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ 2 test was used to compare the constituent ratio of enumeration data among groups. Results:There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups ( t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L ( t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively ( t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L ( t=7.01, P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L ( t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s ( Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s ( Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion:Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.

ABSTRACT
Objective Evaluation of Chinese-thyroid imaging reporting and data system(C-TIRADS)combined with contrast-enhanced ultrasound(CEUS)for the assessment of category 4 nodules in the setting of Hashimoto's thyroiditis.Methods Retrospective analysis of 120 C-TIRADS category 4 thyroid nodules from 79 patients with confirmed Hashimoto's thyroiditis who attended the Yiyang Central Hospital from June to December 2022.Thyroid nodules exhibiting one or more benign or malignant features that were suspicious on CEUS were treated as downgraded or upgraded one level.Using the final surgical pathology results as the gold standard,working characteristic(ROC)curves of subjects based on C-TIRADS grading before and after CEUS adjustment were plotted to compare diagnostic efficacy.Results The sensitivity,specificity,and accuracy of the CEUS-adjusted C-TIRADS were 93.0％,87.8％and 90.8％,respectively(P<0.05).The area under the ROC curve was 0.811 and 0.904,respectively(P<0.05).Conclusion C-TIRADS combined with CEUS has better diagnostic efficacy in evaluating category 4 nodules in Hashimoto's thyroiditis.
ABSTRACT
La encefalopatía de Hashimoto es una entidad poco frecuente, con una amplia gama de manifestaciones neurológicas que incluyen déficits focales, alteraciones cognitivas, crisis convulsivas, trastorno del movimiento e incluso el coma. Con un curso de la enfermedad de subagudo a fluctuante. Afecta más a mujeres que a hombres, con edad de presentación alrededor de los 44 años, aunque se han reportado casos en la edad pediátrica. De etiología poco clara, se desarrolla en el contexto de la presencia de anticuerpos antitiroideos, independientemente de la función tiroidea. La presencia de estos anticuerpos, sumado a la exclusión de otras etiologías y la respuesta al manejo esteroide son claves para su diagnóstico. Presentamos un caso clínico de una mujer de 57 años de edad que evoluciona con psicosis, alteración del lenguaje, deterioro cognitivo, mioclonías y crisis convulsivas de 5 meses de evolución, quien se excluyó otras causas de demencia rápidamente progresiva con presencia de anticuerpos anti tiroglobulina de 83,6 UI/mL (V.R. < 100 UI/mL) normal y anti tiroperoxidasa en 217 UI/mL (V.R. < 100 UI/mL) elevado. Recibió valoración por el Servicio de Endocrinología, donde se detectó hipotiroidismo y se indicó manejo con levotiroxina sin mejoría del cuadro neurológico. Se indicó manejo esteroide con pulsos de metilprednisona a 500 mg/día por 5 días, con mejoría clínica y se concluyó por criterios de exclusión como una encefalopatía de Hashimoto(AU)
Hashimoto encephalopathy is a rare entity, with wide range of neurological manifestations including focal deficits, cognitive alterations, seizures, movement disorders, and even coma, with a subacute to fluctuating disease course. It affects more women than men, it has age of presentation around 44 years, although cases have been reported in the pediatric age. Its etiology is unclear, it develops in the presence of antithyroid antibodies, regardless of thyroid function. The presence of these antibodies, added to the exclusion of other etiologies and the response to steroid management are key to the diagnosis. We report a clinical case of a 57-year-old woman who evolved with psychosis, language impairment, cognitive impairment, myoclonus, and seizures of 5 month-duration. Other causes of rapidly progressive dementia with the presence of normal antithyroglobulin antibodies of 83.6 IU/mL (RV < 100 IU/mL) and elevated antithyroperoxidase 217 IU/mL (RV < 100 IU/mL) were excluded. She was evaluated in the Endocrinology Department that detected hypothyroidism and indicated management with levothyroxine with no improvement in the neurological condition. Steroid management with methylprednisone pulses at 500 mg/day for 5 days was indicated. Clinical improvement was observed and was concluded to be a Hashimoto encephalopathy by exclusion criteria(AU)

Background: Thyroid gland is an endocrine organ. The non-neoplastic and neoplastic conditions affecting the gland can manifest as the swelling of the gland with thyroid dysfunction. Based on cytology, the diseases can be categorized into non-neoplastic, benign neoplastic, and malignant neoplastic conditions and according to hormone status, the lesions of thyroid can be categorized in hypothyroid, euthyroid, or hyperthyroid condition. Aims and Objectives: Our study was done to find out the various cytomorphological spectrum of thyroid diseases and to record their common clinical presentation along with hormonal status in a tertiary care hospital in Northern Odisha. Materials and Methods: A total of 220 cases of thyroid disorder were taken for analysis over a period of 2 years. Patients demographic data, brief clinical features, finding on FNAC (cytomorphology), and thyroid function status were analyzed with appropriate statistical method. Results: The predominant age group affected was 21–40 years and total female to male patient ratio was 5.5:1. Most common presentations were heat intolerance (22.27%), cold intolerance (28.63%), and tachycardia (27.72%) apart from thyroid enlargement. Most common non-neoplastic lesion were multinodular and colloid goiter constituting 38.18% of total cases and most common neoplastic lesion was papillary carcinoma constituting 14.55% of total cases. Thyroid function test showed predominantly euthyroid states for all conditions. Conclusion: As the rest part of India, this part of Odisha also showed that thyroid disorders are more common in females and the most affected age group is 21–40 years. Multinodular and colloid goiter are the most common thyroid lesions. Most of the cases present with euthyroid state.

ABSTRACT
Objective:To analyze the metabolic mechanism of papillary thyroid cancer(PTC) in normal and Hashimoto′s thyroiditis(HT) background, and to explore the relationship between HT and PTC.Methods:This study included a matched sample set collected from Tianjin Medical University General Hospital between January 2018 and January 2019, consisting of PTC and paracancular tissue from 31 cases with coexisting HT(HT group), and 30 cases without(NC group), all confirmed pathologically following thyroidectomy. The ultra-high performance liquid chromatography combined with mixed four-stage poles time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to acquire data from the samples. Metabolite differences between the two groups were compared, aiming to identify distinct metabolic mechanisms of PTC under different backgrounds. Metabolic pathway analysis was conducted using Metabo-Analyst 5.0 to explore relevant metabolic pathways.Results:The HT group and NC group shared 7 common differentially expressed metabolites, including arginine, glutamic acid, cysteine, citric acid, malic acid, uracil, and taurine. Logistic regression model combined with receiver operating characteristic(ROC) analysis of these 7 biomarkers yielded excellent discriminatory capacity for PTC(area under ROC curve of HT group and NC group were 0.867 and 0.973, respectively). The common metabolic pathways were taurine and hypotaurine metabolism, arginine biosynthesis, alanine, aspartic acid and glutamic acid metabolism, arginine and proline metabolism, and glutamine and glutamic acid metabolism. The specific metabolic pathways in HT group were aminoacyl tRNA biosynthesis, glycine, serine, and threonine metabolism.Conclusion:The metabolic profiles of thyroid cancer exhibit significant differences between cases with normal backgrounds and those with HT. The specific pathways for PTC and HT are aminoacyl tRNA biosynthesis and the metabolism of glycine, serine, and threonine.
ABSTRACT
Objective:To investigate the gut microbiota composition in subclinical hypothyroidism and euthyroidism patients with Hashimoto′s thyroiditis, and its relationship with clinical indicators and inflammatory factors.Methods:A total of 48 patients diagnosed with Hashimoto′s thyroiditis and 28 healthy controls(HC group) were enrolled from Henan Provincial People′s Hospital from July 2019 to March 2022 in this cross-sectional study. According to thyroid function, 18 patients with Hashimoto′s thyroiditis were divided into subclinical hypothyroidism group(SH group) and 30 patients in euthyroidism function group(Eu group). Fecal microbial composition was detected by 16S rRNA sequencing technology, and peripheral blood was collected to test clinical indicators and inflammatory factors.Results:Compared with HC group, there were significant differences in α and β diversity of gut microbiota in SH and Eu group( P=0.045, P=0.037). At the phylum level, Firmicutes, Bacteroidota, and Proteobacteria were the dominant phylum in the three groups. At the genus level, the abundance of 4 bacterial genera increased gradually in HC group, Eu group, and SH group, including Streptococcus, Comamonas, Elizabethkingia, Achromobacter. However, the abundance of the other 9 genera decreased gradually, such as Subdoligranulum, Coprococcus, Oscillospirales_ UCG-010, Clostridia_ UCG-014, Oscillospiraceae_ UCG-002, Alistipes et al. In addition, the level of serum B-cell activating factor was positively correlated with several bacterial genera such as Achromobacter, Streptococcus, Intestinibacter et al. Conclusion:There are differences in the gut microbiota structure of patients with Hashimoto′s thyroiditis in different thyroid functional states, which is correlated with inflammatory factors.

ABSTRACT
Objective:To explore the risk factors of central lymph node metastasis (CLNM) in Hashimoto thyroiditis (HT) patients with thyroid micropapillary carcinoma (PTMC), and formulate a reasonable range of lymph node.Methods:Retrospective analysis of 448 cases of PTMC admitted to the People′s Hospital of Inner Mongolia Autonomous Region from September 2018 to September 2021 including 94 males and 354 females, with a male female ratio of 1.00∶3.77, all patients aged 21 to 82 years old, with the average of (46.9 ± 11.0) years old. According to whether Hashimoto thyroiditis (HT) is combined, it is divided into HT-PTMC group ( n=142) and non HT-PTMC group ( n=306).Single factor analysis and multiple factor analysis were used to explore whether the clinicopathological characteristics of patients such as gender, age, tumor diameter, number of lesions (single/multiple lesions), presence of capsule invasion, pretracheal/paratracheal lymph nodes, delphian lymph nodes, and lateral cervical lymph nodes were related to lymph node metastasis in the central region. SPSS 20.0 software was used for statistical analysis and logistic regression equation was established, The mathematical model was used to evaluate the predictive value of diagnosis and treatment. Results:There were significant differences between HT-PTMC group and non HT-PTMC group in terms of age, sex, metastasis of anterior laryngeal lymph nodes and lateral cervical lymph nodes ( P<0.05). Univariate analysis showed that tumor diameter, number of lesions, capsule invasion, calcification, lateral cervical lymph node metastasis were correlated with CLNM in HT-PTMC patients ( P<0.05). Multivariate logistic regression analysis showed that tumor diameter increase and capsule invasion were independent risk factors for CLNM ( P<0.05). Logistic regression mathematical model was established according to the above independent risk factors: (Y=-1.974+ 0.191 × Tumor diameter+ 1.139 × The area under the ROC curve for predicting CLNM in HT-PTMC patients was 0.669 (95% CI: 0.571- 0.766). When taking the maximum Jordan index, the sensitivity of prediction was 0.460, and the specificity was 0.859. Conclusions:For PTMC patients with HT, there is evidence that the tumor diameter increases or the capsule is invaded, and the risk of lymph node metastasis in the central region is increased. Preventive lymph node dissection in the central region is recommended.
ABSTRACT

There were 189 male patients, and 493 female patients, 529 patients < 55 years old and 153 patients ≥55 years old. 476 patients were classified as PTC group and 206 patients as PTC combined with HT group. Chi square test was used to compare the difference between two groups in gender, age, thyroglobulin antibody, thyroid stimulating hormone, thyroid peroxidase antibodies, thyroid peroxidase, number of lesions, metastasis lymph node in central region, thyroid stimulating hormone receptor antibody, carcinoembryonic antigen, whether microcarcinoma, vascular invasion, glandular outside violation, capsule and lateral transfer analysis, ultrasonic calcification, etc. At the same time, all patients were divided into the group without central lymph node metastasis (345 cases) and the group with central lymph node metastasis (337 cases) . The χ 2 test was used to compare the differences between the two groups in terms of sex, age, number of lesions, microcarcinoma, vascular invasion, extradular invasion, capsular invasion, lateral cervical lymph node metastasis, ultrasonic calcification and so on, so as to analyze the differences in clinical characteristics between the two groups. Results:There were 206 cases (30.21%) in PTC combined with HT group and 476 cases (69.79%) in PTC without HT group. There were significant differences in gender (12/194 vs 177/299) ( P=0.000) , age (175/31 vs 354/122) ( P=0.002) , TgAb (115/91 vs 455/21) ( P=0.000) ,TSH (13/175/18 vs 33/429/14) ( P=0.004) , TPOAb (90/116 vs 422/54) ( P=0.000) , number of lesions (114/92 vs 325/151) ( P=0.001) and lymph node metastasis in central area (87/119 vs 250/226) ( P=0.014) between the two groups ( P < 0.05) , but there were no significant differences in TRAb (196/10 vs 461/15) ( P=0.171) , CEA (205/1 vs 469/7) ( P=0.478) , microcarcinoma (136/70 vs 309/167) ( P=0.781) , vascular invasion (4/202 vs 16/460) ( P=0.446) , extraglandular invasion (52/154 vs 108/368) ( P=0.470) , capsule invasion (149/57 vs 358/118) ( P=0.429) , lateral neck lymph node metastasis (31/175 vs 72/404) ( P=0.979) or ultrasonic calcification (157/49 vs 392/84) ( P=0.063) . Compared with PTC group, PTC combined with HT group had the characteristics of more women, younger age, high TgAb, high TSH, high TPOAb, multiple lesions and high proportion of non central lymph node metastasis. There were 345 cases (50.59%) without central lymph node metastasis and 337 cases (49.41%) with central lymph node metastasis. Gender (71/274 vs 118/219) ( P=0.000) , age (246/99 vs 283/54) ( P=0.000) , exadular invasion (66/279 vs 94/243) ( P=0.007) , number of lesions (240/105 vs 199/138) ( P=0.004) , microcarcinoma (259/86 vs 186/151) ( P=0.000) , calcification on ultrasound (250/95 vs 299/38) ( P=0.000) , and HT (119/226 vs 87/250) ) ( P=0.014) had statistical significance ( P<0.05) but had no statistical significance in capsule invasion (250/95 vs 257/80) ( P=0.256) or vascular invasion (10/335 vs 10/327) ( P=0.958) . In addition, patients in the group with central lymph node metastasis were more male, younger, with multiple lesions, exadenocarcinoma, less microcarcinoma, and calcification on ultrasound without hashimoto. Univariate analysis showed that gender, age, number of lesions, extraglandular invasion, calcification, microcarcinoma and Hashimoto had significant effects on lymph node metastasis in the central region; Multivariate analysis showed that the presence of microcarcinoma, ultrasonic calcification, Hashimoto and the number of lesions were independent risk factors for central lymph node metastasis. Conclusion:HT may promote the occurrence of PTC, but at the same time inhibit its development, so that PC patients with HT have a better prognosis.
ABSTRACT
Objective:To study the value of CT texture analysis (CTTA) parameters in differential diagnosis of benign and malignant thyroid nodules in Hashimoto’s thyroiditis.Methods:From May. 2020 to Oct. 2021, 110 patients with thyroid nodules in the background of Hashimoto’s thyroiditis in the Radiology Department of Nanjing Integrated Hospital of Traditional Chinese and Western Medicine were selected, and CTTA was performed. CTTA parameters (entropy value, peak state and skewness) were counted. The pathological diagnosis results were taken as the "gold standard". Statistical pathological examination results were used to compare the general clinical characteristics and CTTA parameters of benign and malignant thyroid nodules. The receiver operating characteristic (ROC) was used to analyze the diagnostic value of CTTA parameters for thyroid nodules.Results:According to the clinicopathological examination, 43 of 110 patients with Hashimoto’s thyroiditis were malignant, accounting for 39.09%. Among them, 22 were papillary carcinoma, 13 were follicular carcinoma, 6 were medullary carcinoma, and 2 were malignant lymphoma; 67 cases were benign, accounting for 60.91%, including 32 nodular goiters, 20 Hashimoto’s nodules, 8 thyroid adenomas, and 7 focal inflammation. The levels of TSH, irregular shape, blurry border and calcification in patients with malignant thyroid nodules were higher than those in patients with benign thyroid nodules ( t/ χ2=13.167, 18.364, 20.180,17.621, P<0.001). In the background of Hashimoto’s thyroiditis, there was no significant difference in the peak and skewness of CTTA parameters between benign and malignant thyroid nodules ( t=1.633, 1.382, P=0.105, 0.170). The entropy value of patients with malignant thyroid nodules was higher than that of patients with benign thyroid nodules, and the difference was statistically significant ( t=9.862, P<0.001). ROC analysis showed that the cut-off value of entropy value for diagnosing benign and malignant thyroid nodules was 6.28, AUC value was 0.909, 95% CI was 0.839-0.955, sensitivity was 86.05% (37/43), and specificity was 88.06% (69/67) . Conclusion:CTTA parameters in Hashimoto’s thyroiditis patients with benign and malignant thyroid nodules are different, and CTTA parameters have certain diagnostic value for benign and malignant thyroid nodules.
