Objective To analysis causes of reoperation for primary hyperparathyroidism and its clinical characteristics. Method The clinical data of the patients with primary hyperparathyroidism who had undergone reoperation from January 1993 to May 2017 were retrospectively analyzed. Results A total of 11 patients underwent reoperation were collected in the 226 patients with primary hyperparathyroidism. Of the 11 cases, 8 cases underwent twice operations, 2 cases underwent thrice operations, 1 case underwent quintic operation. After the initial operation, 3 cases were persistent diseases and 7 cases were recurrent diseases, 1 patient was not defined as the persistent or recurrent disease. The main clinical manifestations before the reoperation were fatigue, pain in joints, bones, or muscle. The reasons for reoperation included 3 cases of ectopic parathyroid lesions, 3 cases of recurrent parathyroid carcinomas, 1 case of enlarged operation extent for parathyroid carcinoma, 2 cases of regrowth of double parathyroid aedomas, 1 case of missing adenoma, 1 case of parathyroid hyperplasia. Among the location examinations, the 99Tcm-MIBI was most sensitivity (8/9). Eight cases were received reoperation on the original incision, and the remaining 3 ectopic parathyroid lesions on the new incision. After the reoperation, 2 patients were lost of follow-up, 1 patient died, and the remaining 8 patients had no recurrences during follow-up period. Conclusion A comprehensive approach with multiple imageology examinations which attribute to accurate location of lesions, experienced surgeons and well knowledge of parathyroid anatomy and embryology help to descend reoperation ratio and improve success rate of reoperation.
【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.
ObjectiveTo explore the association between single nucleotide polymorphism (SNP) in the X-ray cross complementary repair gene-1 (XRCC1) rs1799782 locus and thyroid cancer.MethodsStudies investigating the association between SNP in the XRCC1 gene and thyroid cancer susceptibility were retrieved from the PubMed, Embase, Web of Science, CNKI (Chinese National Knowledge Infrastructure), Wanfang, and CBM (China Biology Medicine) databases (published date up to February 15, 2021). Eligible studies were screened according to inclusion/exclusion criteria and principles of quality evaluation. Meta-analysis was performed using Stata 14.0 software. Odds ratios with their corresponding 95% confidence intervals (95%CI) were pooled to assess the association between SNP in the XRCC1 gene rs1799782 locus and thyroid cancer susceptibility.ResultsTwelve articles were eligible for this meta-analysis. Meta-analysis results were shown as follows: No significant association was found between XRCC1 rs1799782 polymorphism and thyroid cancer in overall population [Dominant model: CT+TT vs CC, OR=1.07, 95%CI (0.84, 1.36). Recessive model: TT vs CT+CC, OR=1.48, 95%CI (0.95, 2.31). Allelic model: T vs C, OR=1.15, 95%CI (0.93, 1.43). Codominant model: TT vs CC: OR=1.44, 95%CI (0.83, 2.53); CT vs CC, OR=1.02, 95%CI (0.82, 1.28); TT vs CT, OR=1.40, 95%CI (0.98, 1.99)]. rs1799782 polymorphism was significantly associated with the risk of thyroid cancer in Chinese population [Dominant model: CT+TT vs CC, OR=1.38, 95%CI (1.11, 1.71). Recessive model : TT vs CT+CC, OR=1.97, 95%CI (1.55, 2.50); Allelic model: T vs C, OR=1.40, 95%CI (1.16, 1.68). Codominant model: TT vs CC, OR=2.12, 95%CI (1.66, 2.71); CT vs CC, OR=1.26, 95%CI (1.09, 1.47); TT vs CT, OR=1.70, 95%CI (1.31, 2.21)]. rs1799782 polymorphism was significantly associated with the risk of thyroid cancer in Asian population [Dominant model: CT+TT vs CC, OR=0.64, 95%CI (0.49, 0.83). Codominant model: TT vs CC: OR=0.50, 95%CI (0.33, 0.74); CT vs CC, OR=0.65, 95%CI (0.49, 0.86)].ConclusionsThere is no significant correlation between XRCC1 rs1799782 polymorphism and the risk of thyroid cancer in general population. The XRCC1 rs1799782 polymorphism may be associated with an increased thyroid cancer risk among Chinese, and a tendency for decreased thyroid cancer risk among Asians (Chinese excluded). The XRCC1 rs1799782 polymorphism is not associated with thyroid cancer susceptibility among Caucasians under all genetic models.
Objective The aim of this study is to review the association between long non-coding RNA (lncRNA) and papillary thyroid carcinoma (PTC). Method The relevant literatures about lncRNA associated with PTC were retrospectively analyzed and summarized. Results The expression levels of noncoding RNA associated with MAP kinase pathway and growth arrest (NAMA), PTC susceptibility candidate 3 (PTCSC3), BRAF activated non-coding RNA (BANCR), maternally expressed gene 3 (MEG3), NONHSAT037832, and GAS8-AS1 in PTC tissues were significantly lower than those in non-thyroid carcinoma tissues. The expression levels of ENST00000537266, ENST00000426615, XLOC051122, XLOC006074, HOX transcript antisense RNA (HOTAIR), antisense noncoding RNA in the INK4 locus (ANRIL), and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in PTC tissues were upregulated in PTC tissues, comparing with the non-thyroid carcinoma tissues. These lncRNAs were possibly involved in cell proliferation, migration, and apoptosis of PTC. Conclusion LncRNAs may provide new insights into the molecular mechanism and gene-targeted therapy of PTC and become new molecular marker for the diagnosis of PTC.
ObjectiveTo summarize the risk factors of the change of voice quality after thyroidectomy without recurrent laryngeal nerve injury and to provide reference for the prevention and treatment of postoperative voice quality damages.MethodThe research progress of the change of voice quality after thyroidectomy without recurrent laryngeal nerve injury was reviewed by reading the related literatures at home and abroad.ResultsEven if there was no obvious recurrent laryngeal nerve injury during the operation, the voice quality may change after the operation for the patients undergoing thyroidectomy. The change of voice quality after thyroidectomy without recurrent laryngeal nerve injury was associated with various risk factors such as dysfunction of superior laryngeal nerve, injury of anterior laryngeal band muscles, endotracheal intubation, surgical methods, age, gender and special occupations.ConclusionsThe change of voice quality is a common complication after thyroidectomy, which seriously affects the quality of life of patients. In the absence of significant recurrent laryngeal nerve injury, many patients will still experience problems with voice quality. Understanding the related risk factors of voice quality change after thyroidectomy is helpful to optimize postoperative voice function, to prevent possible secondary injuries, and to improve the quality of life of patients.
【Abstract】ObjectiveTo investigate the technique of establishing a model of aparathyroid rat which could be used in the study of parathyroid cells transplantation. Methods Parathyroid glands were surgically excised and identified pathologyically. Serum calcium and parathyroid hormone in rats before operation and on day 2，5，10，15 and 30 after operation were measured. Results Parathyroid glands were resected successfully in 8 rats, and the resection rate was 80% (8/10). No obvious changes of serum calcium and parathyroid hormone levels were found before and after operatiion in sham parathyroid gland excision group (Pgt;0.05). However, statistically significant changes of those data were found perioperatively in parathyroid gland excision group (P＜0.01). Conclusion The model of aparathyroid rat can be established successfully after parathyroid glands in rats are excised exactly. Parathyroid allotransplantation could be performed ten days after parathyriodectomy.
Objective To summarize the value of serum thyroglobulin (Tg) in diagnosis before surgery and monitoring after surgery for differentiated thyroid cancer (DTC). Methods By using the method of literature review, the literatures related to the diagnosis and monitoring value of serum Tg for DTC were studied. Results ① Serum thyroglobulin had a certain value in diagnosis of thyroid nodules, especially in follicular cancer or Hürthle cancer whose diagnosis undetermined by fine-needle aspiration biopsy (FNAB), and it was closely linked with the tumor’s size and distant metastasis of the DTC. ② Raise of serum Tg postoperatively was important for judging the recurrence and metastasis of DTC. However, how to establish an appropriate threshold of serum Tg, identify the differences of results for different measurement methods, make the accurate judgment for false positive and false negative, and combine with other imaging methods appropriately, needed our attention. Conclusion Serum Tg plays a very important role in diagnosis before surgery and monitoring after surgery of DTC, clinical doctors need pay high attention on it.
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.
