ObjectiveTo summarize the role of circular RNA (circRNAs) in thyroid papillary carcinoma (PTC) and the emphasis of future research.MethodRelevant literatures in recent years about the biological function of circRNA and its role in PTC were reviewed.ResultscircRNAs had abnormal expression in PTC tissues. Besides, by working as miRNA sponges or interacting with RNA-binding proteins, circRNAs regulated the expression of proteins that were associated with cell proliferation, apoptosis, invasion, and metastasis, which could affect the biological characteristics of tumor cells.ConclusioncircRNAs are expected to be the biomarkers for early diagnosis of PTC or potential targets for PTC therapy and provid therapeutic bases to prevent PTC.
ObjectiveTo investigate the diagnosis and treatment value of multi-disciplinary team (MDT) model in patient with gastric perforation combined with hyperthyroidism crisis.MethodWe summarized the experiences of MDT model in treating one case of gastric perforation with hyperthyroidism crisis in the Fuling Central Hospital of Chongqing City on February 2019.ResultsThis patient had a history of hyperthyroidism and didn’t receive systemic treatment, diagnosing as acute diffuse peritonitis and perforation of hollow organs. After MDT discussions and a series of treatments, including anti-infection, control of heart rate and hyperthyroidism, this patient underwent surgical treatment of gastric peptic ulcer perforation, during and after the surgery, this patient suffered from hyperthyroid crisis. The surgery was successful, with the operation time was about 110 min, and the blood loss was about 50 mL. There was no side injury occurred without blood transfusion, and the patient was cured and discharged on 20 days after operation. The patient was followed up for about 1 year, and the general condition and life returned to normal.ConclusionMDT discussion is a very helpful way in the treatment of gastric perforation combined with hyperthyroidism crisis and can give a better outcome.

Methods The pertinent literatures in recent thirty years were screened with key words “parathyroid micro vascular anatomy， capsular technique， and protection”and reviewed. Results There were many types of number， origin， and length of parathyroid vascular， and specific measurements should be taken in thyroid lobectomy with capsular technique. Conclusion Fully awareness of parathyroid micro vascular anatomy will benefit to ensure preservation of their function during thyroid lobectomy with capsular technique.
ObjectiveTo evaluate the safety and effectiveness of total hip arthroplasty (THA) in patients with hypothyroidism.MethodsSixty-three patients with hypothyroidism (hypothyroidism group) and 63 euthyroid patients without history of thyroid disease (control group) who underwent primary unilateral THA between November 2009 and November 2018 were enrolled in this retrospective case control study. There was no significant difference between the two groups in gender, age, body mass index, hip side, reason for THA, American Society of Anesthesiology (ASA) classification, preoperative hemoglobin (Hb) level, and preoperative Harris score (P>0.05). The perioperative thyroid stimulating hormone (TSH) and thyroxine (T4) levels, the hypothyroidism-related and other complications during hospitalization, the decrease in Hb, perioperative total blood loss, blood transfusion rate, length of hospital stays, and 90 days readmissions rate in the two groups were recorded and evaluated. The periprosthetic joint infection, aseptic loosening of the prosthesis, and hip Harris score during follow-up were recorded.ResultsThe differences in the TSH and T4 of hypothyroidism group between pre- and 3 days post-operation were significant (P>0.05) and no hypothyroidism-related complications occurred after THA. The decrease in Hb and perioperative total blood loss in the hypothyroidism group were significantly higher than those in the control group (P<0.05), but there was no significant difference between the two groups in terms of transfusion rate, length of hospital stays, and 90 days readmission rates (P>0.05). No significant difference in the rate of complications (liver dysfunction, heart failure, pulmonary infection, urinary infection, and wound complication) between the two groups was found (P>0.05) except for the rate of intramuscular vein thrombosis which was significantly lower in the hypothyroidism group, and the rate of postoperative anemia which was significantly higher in the hypothyroidism group (P<0.05). The two groups were followed up 1.0-9.9 years (mean, 6.5 years). At last follow-up, Harris score in both groups were significantly higher than those before operation (P<0.05). An increase of 39.5±12.3 in hypothyroidism group and 41.3±9.3 in control group were recorded, but no significant difference was found between the two groups (t=0.958, P=0.340). During the follow-up, 1 case of periprosthetic joint infection occurred in the hypothyroidism group, no loosening or revision was found in the control group.ConclusionWith the serum TSH controlled within 0.5-3.0 mU/L and T4 at normal level preoperatively, as well as the application of multiple blood management, hypothyroid patients can safely go through THA perioperative period and effectively improve joint function, quality of life, and obtain good mid-term effectiveness.
ObjectiveTo systematically review the efficacy and safety of recombinant human TSH (rhTSH) in radioiodine therapy for benign thyroid goiter. MethodsWe electronically searched MEDLINE, EBSCO, The Cochrane Library (Issue 6, 2015) and CNKI databases from January 1990 to March 2015, to identify randomized controlled trials (RCTs) about rhTSH in radioiodine therapy of benign thyroid goiter. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies, and then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 6 RCTs were included. The results of meta-analysis showed that: compared with the control group, the thyroid volume was significantly reduced at 1 year after radiation in the rhTSH group (MD=0.14, 95%CI 0.05 to 0.23, P=0.002). There were no significant differences in FT4, FT3 and the percentage of patients who had thyroid antibody between two groups before and after radiation. In addition, rhTSH did not significantly increase the incidence of hyperthyroidism and neck pain. ConclusionrhTSH is effective and safe in radioiodine therapy of benign thyroid goiter. Due to the limitation of quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
This is the first successful case expriences,a method of the procurement of the fetal cadavertic multiple argans for transplantation of the pancreas and thyroid-pararthyroid glands was produced. The liver,pancreas,duodenum,spleen,and both kidneys were harvested en bloc by a group of surgeons,and the right hem-ithyroid-parathyroid glands with pedicle of thd blood vessels wre removed by another group.The pancreas together with the spleen were transplanted to a patient having diabetes mellitus. The thyroid-parathyroid glands were given to another case with bypothyroidism and hypoparathyroidism.Both cases had good results.This method had dicreased the warm ischemia of the transplants,and could provide liver,pancreas,spleen,kidneys and thyroid-parathyroid glands to solve the problem of shortage of fetal organs.
Objective To explore the effect of preoperative hypothyroidism on postoperative cognition dysfunction (POCD) in elderly patients after on-pump cardiac surgery. Methods Patients who were no younger than 50 years and scheduled to have on-pump cardiac surgeries were selected in West China Hospital from March 2016 to December 2017. Based on hormone levels, patients were divided into two groups: a hypo group (hypothyroidism group, thyroid stimulating hormone (TSH) >4.2 mU/L or free triiodothyronine 3 (FT3) <3.60 pmol/L or FT4 <12.0 pmol/L) and an eu group (euthyroidism group, normal TSH, FT3 and FT4). The mini-mental state examination (MMSE) test and a battery of neuropsychological tests were used by a fixed researcher to assess cognitive function on 1 day before operation and 7 days after operation. Primer outcome was the incidence of POCD. Secondary outcomes were the incidence of cognitive degradation, scores or time cost in every aspect of cognitive function. Results No matter cognitive function was assessed by MMSE or a battery of neuropsychological tests, the incidence of POCD in the hypo group was higher than that of the eu group. The statistical significance existed when using MMSE (55.56% vs. 26.67%, P=0.014) but was absent when using a battery of neuropsychological tests (55.56% vs. 44.44%, P=0.361). The incidence of cognitive deterioration in the hypo group was higher than that in the eu group in verbal fluency test (48.15% vs. 20.00%, P=0.012). The cognitive deterioration incidence between the hypo group and the eu group was not statistically different in the other aspects of cognitive function. There was no statistical difference about scores or time cost between the hypo group and the eu group in all the aspects of cognitive function before surgery. After surgery, the scores between the hypo group and the eu group was statistically different in verbal fluency test (26.26±6.55 vs. 30.23±8.00, P=0.023) while was not statistically significant in other aspects of cognitive function. Conclusion The incidence of POCD is high in the elderly patients complicated with hypothyroidism after on-pump cardiac surgery and words reserve, fluency, and classification of cognitive function are significantly impacted by hypothyroidism over than other domains, which indicates hypothyroidism may have close relationship with POCD in this kind of patients.
Objective To establish a predictive model for long-term tumor-specific survival after surgery for patients with intermediate to advanced medullary thyroid cancer (MTC) based on American Joint Committee on Cancer (AJCC) TNM staging, by using the Surveillance, Epidemiology, and End Results (SEER) Database. Methods The data of 692 patients with intermediate to advanced MTC who underwent total thyroidectomy and cervical lymph node dissection registered in the SEER database during 2004–2017 were extracted and screened, and were randomly divided into 484 cases in the modeling group and 208 cases in the validation group according to 7∶3. Cox proportional hazard regression was used to screen predictors of tumor-specific survival after surgery for intermediate to advanced stage MTC and to develop a Nomogram model. The accuracy and usefulness of the model were tested by using the consistency index (C-index), calibration curve, time-dependent ROC curve and decision curve analysis (DSA). Results In the modeling group, the multivariate Cox proportional hazard regression model indicated that the factors affecting tumor-specific survival after surgery in patients with intermediate to advanced MTC were AJCC TNM staging, age, lymph node ratio (LNR), and tumor diameter, and the Nomogram model was developed based on these results. The modeling group had a C-index of 0.827 and its area under the 5-year and 10-year time-dependent ROC curves were 0.865 [95%CI (0.817, 0.913)], 0.845 [95%CI (0.787, 0.904)], respectively, and the validation group had a C-index of 0.866 and its area under the 5-year and 10-year time-dependent ROC curves were 0.866 [95%CI (0.798, 0.935)] and 0.923 [95%CI (0.863, 0.983)], respectively. Good agreement between the model-predicted 5- and 10-year tumor-specific survival rates and the actual 5- and 10-year tumor-specific survival rates were showed in both the modeling and validation groups. Based on the DCA curve, the new model based on AJCC TNM staging was developed with a significant advantage over the former model containing only AJCC TNM staging in terms of net benefits obtained by patients at 5 years and 10 years after surgery. Conclusion The prognostic model based on AJCC TNM staging for predicting tumor-specific survival after surgery for intermediate to advanced MTC established in this study has good predictive effect and practicality, which can help guide personalized, precise and comprehensive treatment decisions and can be used in clinical practice.
Objective To explore value of multidisciplinary team (MDT) model in diagnosis and treatment of patients with advanced special thyroid cancer who lost chance of operation. Method Two patients with the advanced special thyroid cancer who lost chance of operation were treated by low dose apatinib (250 mg/d) after the MDT discussion. Results One medullary thyroid cancer patient with the compressing of the trachea for mediastinal metastatic lymphadenopathy and inability to lie down underwent the multiple surgical treatment, the therapeutic effect was poor. Then low dose apatinib (250 mg/d) was performed, the patient could supine, breathe smoothly, and move freely, whose life quality was obviously improved, the mediastinal lymph nodes reduced and no serious drug toxicity occurred on month 1 after the treatment. One undifferentiated thyroid cancer patient with the lung metastasis, hemoptysis, and tumor invasion resulted in the inability to lie down and having difficulty in breathing, these symptoms still existed and more pleural effusion occurred after the resection of the invaded trachea. Then low dose apatinib (250 mg/d) was performed, the patient could supine, the pleural effusion disappeared, the hemoptysis stopped, the breathing was smooth, and could do some minor housework, no drug toxicity occurred on month 1 after the treatment. Conclusion After MDT discussion, low dose apatinib in treatment of advanced special thyroid cancer is reliable and safe and has a good short-term effect, which could be used as a new remedy, but long-term effect should be further researched by increasing case samples and a long-term following-up.
ObjectiveTo explore the clinical characteristics, diagnosis and treatment of ectopic thyroid gland (ETG) so as to reduce the misdiagnosis and improper treatment. MethodsAccording to the patients who were definitely diagnosed ETG by pathology from 2002 to 2010 in our hospital, their clinical and pathological data were retrospectively analyzed. ResultsThere were 14 patients, 4 cases of male and 10 cases of female. Five patients had clinical symptoms. Eight cases were diagnosed before operation and six cases were diagnosed by pathology after operation. There were 4 cases were malignancy and 10 were benign. Three cases of differentiated ectopic thyroid carcinoma patients and 1 normal position's thyroid had papillary carcinoma patient accepted TSH suppression treatment after operation, 4 benign patients and 1 ectopic thyroid medullary carcinoma patient accepted levothyroxine substitution treatment after operation, and the other 5 benign patients did not accept any treatment after operation. Nine patients who accepted follow-up in 1-10 years had orthobiosis, and the malignancy patients without recurrence and metastasis. ConclusionsETG usually reveal no any special clinical features. For any masses from root of tongue to mediastinum, especially cervical masses, should be carefully check whether there are thyroid in normal position, and to exclude ETG. The color Doppler ultrasound, thyroid radioactive scanning, thyroid function tests, computed tomography, and fine needle aspiration cytology are all important examination measures. Due to the ETG may occur the same lesions as the normal position's thyroid, so once it is be definitly diagnosed, the treatment should be based on patient's age, position, size, and type of ETG, and nature of the lesions to select follow-up observation, operative treatment, levothyroxine replacement or therapeutic inhibition of TSH, and 131I therapy.
