From May 1982 to September 1994, 13 cases patients with acute suppurative thyroiditis were treated. Their ages ranged from 6 to 39 years with a mean of 13. 9 years (nine of them were children). In this group, 8 cases had a pre-existing thyroid mass. Correct diagnosis were made preoperatively in 11 cases and the other two were misdiagnosed before operation. Eleven patients underwent incision and drainge, amony them 6 cases had been followed up with no recurrence. Based on this result and re-viewing literatures, the author draw the conclusion that acute suppurative thyoiditis is related with fistula of pyriform fossa, incision and drainage must be carried out and if there is fistula present, fistulectomy should be performed.
Thirty patients with heperthyroidism were investigated for triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), thyromicrosome antibody (TMA), thyroglobulin antibody (TGA) and hydrocortisone before and after operation. The levels of serum T3, T4, TGA, TMA were markedly decreased after operation, and the level of hydrocortisone farther decreased from the preoperative low level. But only a little decrease in TSH level was found as compared with that before operation. The assay of these hormones and antibodies has very important clinical significance for judgement of the effect of operation and prevention of crisis of hyperthyroidism.
ObjectiveTo investigate the association between serum thyroid hormone levels and prognosis for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) without thyroid disease, and explore the prognostic value of serum thyroid hormone levels for patients with AECOPD.MethodsThe clinical data of 239 hospitalized cases of AECOPD [149 males, 90 females, aged 42-92 (77.7±8.9) years] from January 2013 to November 2017 were retrospectively analyzed. Serum thyroid hormone levels including total tetraiodothyronin (TT4), total triiodothyronin (TT3), thyroid stimulating hormone (TSH), free tetraiodothyronin (FT4) and free triiodothyronin (FT3) were measured by chemiluminescence immunoassay. All patients were divided into a survival group and a death group according to the prognosis. Serum thyroid hormone levels were compared between two groups. Correlations of serum thyroid hormone levels with the occurrence of death in AECOPD patients were analyzed. The prognostic value of serum thyroid hormone levels for AECOPD patients was explored by receiveroperating characteristic (ROC) curve analysis. And the best cut-off value of serum thyroid hormone level in predicting the risk of death was calculated.ResultsSerum TT4, TT3, FT4 and FT3 levels in the survival group were significantly higher than those in the death group [TT4: (89.35±21.45) nmol/L vs. (76.84±21.33) nmol/L; TT3: (1.05±0.34) nmol/L vs. (0.72±0.19) nmol/L; FT4: (16.17±2.91) pmol/L vs. (14.45±2.85) pmol/L; FT3: (3.06±0.81) pmol/L vs. (2.24±0.72) pmol/L; all P<0.05]. The differences of serum TSH level between two groups were not statistically significant [0.98 (0.54-1.83)vs. 0.57 (0.31-1.84), P>0.05]. Spearman correlation analysis showed that serum TT4, TT3, FT4 and FT3 levels were significant correlated with the occurrence of death (r values were 0.226, 0.417, 0.220, 0.387, respectively, P<0.05). And there was no significant correlation between serum TSH level and the occurrence of death (P>0.05). ROC curve analysis was done between serum thyroid hormone levels (TT4, TT3, TSH, FT4 and FT3) and the occurrence of death in the AECOPD patients. The areas under ROC curve were 0.659, 0.793, 0.588, 0.655 and 0.772, respectively. Serum TT3 was the best indicator for predicting the occurrence of death. When serum TT3 level was 0.85nmol/L, the Youden index was the highest (0.486), with a sensitivity of 70.2%, and a specificity of 78.3%. It was the best cut-offl value of serum TT3 to predict the risk of death in AECOPD patients.ConculsionsSerum thyroid hormone levels are significant associated with the prognostic for AECOPD patients. There is certain value of serum thyroid hormone levels in prognostic evaluation of AECOPD patients.
ObjectiveTo assess the clinical efficacy of percutaneous transplantation of parathyroid glands into the subcutaneous tissue of the epigastrium for treating malignant secondary hyperparathyroidism (SHPT). MethodsThe clinical data of the patients with SHPT who were treated by puncturing the subcutaneous tissue of the epigastrium and transplanting parathyroid glands in the Xuzhou Central Hospital from January 2020 to June 2022 were collected retrospectively. The preoperative and postoperative parathyroid hormone (PTH) level, calcium ion concentration, alkaline phosphatase (ALP) level, and phosphorus ion concentration, as well as postoperative follow-up results were analyzed. The data analysis was conducted using SPSS 23.0 software, with a testing level of 0.01. ResultsA total of 21 patients successfully underwent this surgery, including 12 males and 9 females, with a median age of 48 years old and a range of 32–71 years old. The dialysis time was (8.62±2.27) years, and 12 patients had hypertension, 9 patients had anemia, 17 patients had bone pain, and 11 patients had skin itching. On day 1 after treatment, the PTH level decreased from (1 893.23±539.30) ng/L to (5.99±3.50) ng/L (P<0.001), the calcium ion concentration decreased from (2.52±0.31) mmol/L to (2.24±0.35) mmol/L (P=0.003), and the phosphorus ion concentration decreased from (2.25±0.71) mmol/L to (1.76±0.38) mmol/L (P=0.006) as compared with the values before surgery. Although the ALP level decreased from (321.78±151.01) U/L to (229.32±89.32) U/L, there was no statistically significant difference (P=0.016). Among the 12 patients with hypertension before surgery, 6 patients improved and reduced the use of antihypertensive drugs after surgery; among the 9 patients with anemia, 3 patients improved before discharge; 17 patients with bone pain showed markedly relief before discharge; and 9 patients with skin itching improved before discharge. There were no complications such as hoarseness, choking cough when drinking water, or incision infection after the operation. All 21 patients were followed up for 6–12 months. The parathyroid hormone levels of the 21 patients all dropped to the normal level within 12 months after the operation. Among them, 3 patients recovered to the normal level at the 3rd month after the operation, 16 patients recovered to the normal level at the 6th month after the operation, and 2 patients recovered to the normal level at the 12th month after the operation. The time to return to the normal level was (5.86±2.70) months. No serious complications occurred in all patients, and there was no recurrent case during follow-up period. Conclusion From the analysis results of our study, parathyroid autotransplantation into the subcutaneous tissue of the epigastrium via puncture is a safe and effective method for patients with SHPT.
ObjectiveTo detect expressions of transient receptor potential channel C5 (TRPC5) and microRNA-320a (miR-320a) in thyroid cancer and explore clinical significances of them in thyroid cancer.MethodsThe expressions of TRPC5 and miR-320a mRNA in the thyroid cancer were investigated by searching the Ualcan database. While the expressions of TRPC5 and miR-320a mRNA in 80 cases of thyroid cancer, 35 cases of thyroid adenoma and 32 cases of normal thyroid tissues adjacent to thyroid adenoma tissues in the Zhengzhou Seventh People’s Hospital from March 2014 to March 2015 were tested. Real time PCR was used to detect the expressions of TRPC5 mRNA and miR-320a mRNA in the various tissues and Western blot was used to detect the TRPC5 protein in the thyroid cancer tissues. Therelationships between the expressions of TRPC5 and miR-320a mRNAs and clinicopathologic features of thyroid cancer were analyzed. The correlation between expressions of TRPC5 and miR-320a mRNA was analyzed by Pearson method. The risk factors influencing the prognosis were analyzed by univariate and multivariate Cox proportional hazards regression model.ResultsThe results of Ualcan database showed that the expression level of TRPC5 mRNA in the thyroid cancer was higher than that in the normal thyroid tissue (P<0.001), while the expression level of miR-320a mRNA was lower than that in the normal thyroid tissue (P<0.001). The results of clinical cases showed that the expression level of TRPC5 mRNA was significantly higher, while the expression of miR-320a mRNA was significantly lower in the thyroid cancer tissues as compared with the normal thyroid tissues (P<0.05). There was a negative correlation between the expression level of TRPC5 and miR-320a mRNA in the thyroid cancer (r=−0.653, P<0.001). The expressions of TRPC5 and miR-320a mRNA were correlated with the degree of differentiation, lymph node metastasis, and TNM stage (P<0.05). Kaplan-Meier survival curve analysis found that the patients with higher expression level of TRPC5 and lower expression level of miR-320a showed the poor prognosis, and multivariate analysis found that the lower tumor differentiation, later TNM stage, with lymph node metastasis, higher expression level of TRPC5 mRNA, and lower expression level of miR-320a mRNA were the risk factors affecting prognostic survival (P<0.05).ConclusionsFrom the database and clinical case data, it is concluded that TRPC5 mRNA is highly expressed, while miR-320a mRNA is lowly expressed in thyroid cancer tissues, and expressions of TRPC5 and miR-320a mRNA are related to degree of tumor differentiation, lymph node metastasis, TNM staging, and prognosis in patients with thyroid cancer. TRPC5 and miR-320a mRNA might be used as potential indicators for clinical and prognostic monitoring.
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.
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 investigate the diagnostic significance of fine needle aspiration cytology (FNAC) combined with BRAFV600E gene detection in the diagnosis of cervical lymph node metastasis of thyroid cancer. Methods Atotal of 140 patients with suspected cervical lymph node metastasis of thyroid cancer were collected as the research objects, and all patients were given ultrasound-guided FNAC and detection of BRAFV600E gene.

For FNAC, the sensitivity was 63.6% (84/132), the specificity was 100% (8/8), the accuracy was 65.7% (92/140), the positive predictive value was 100% (84/84), and the negative predictive value was 14.3% (8/56). For detection of BRAFV600E gene, the sensitivity was 84.8% (112/132), the specificity was 100% (8/8), the accuracy was 85.7% (120/140), the positive predictive value was 100% (112/112), and the negative predictive value was 28.5% (8/28). For FNAC combined with BRAFV600E gene detection, the sensitivity was 90.9% (120/132), the specificity was 100% (8/8), the accuracy was 91.4% (128/140), the positive predictive value was 100% (120/120), and the negative predictive value was 40.0% (8/20). The area under curve of receiver operating characteristic for FNAC, detection of BRAFV600E gene, and FNAC combined with BRAFV600E gene detection were 0.818, 0.924, and 0.955, respectively. Conclusion FNAC combine with BRAFV600E gene detection improves the accuracy of neck lymph node metastasis in patients with thyroid cancer, which is worthyof performed.
ObjectiveTo screen prognosis prediction targets related to progression free survival (PFS) for patients with papillary thyroid cancer (PTC) based on the RNA binding proteins (RBPs) gene set. MethodsThe clinicopathologic data of patients with PTC were obtained from UCSC Xena database and the cancer tissues and paired tissue adjacent to cancer (a distance >2.0 cm) of the patients with PTC underwent thyroid surgery were obtained from the First Affiliated Hospital of Zhengzhou University. The differentially expressed RBPs genes between the cancer and normal tissues were determined from the comprehensive analysis of multiple public data sets, and the RBPs genes related to PFS were determined by univariate and multivariate Cox analyses. Western blot method was used to verify the protein expression of RBPs gene in the clinical cases. The RBPs genes with prognostic value and in combination with clinicopathologic parameters were use to establish a nomogram associated with prognostic prediction. Results① A total of 424 patients with PTC were included from the UCSC Xena database and 30 patients with PTC were collected from the First Affiliated Hospital of Zhengzhou University. ② Seven down-regulated RBPs genes (ARHGEF28, IGF2BP2, KHDRBS2, MVP, PPARGC1A, SMAD9, TDRD9) and 3 up-regulated RBPs genes (ZFP36, ZFP36L2, ZMAT3) were identified in PTC. ③ The RBPs gene ZFP36 associated with PFS was screened by multivariate Cox analysis. ④ The Western blot result showed that the expression of ZFP36 protein was basically consistent with its gene expression. ⑤ The areas under the receiver operating characteristics curve of nomogram constructed in combination the clinicopathologic features related to PFS (M stage, T stage) with ZFP36 in predicting 1, 3, and 5-year PFS rates were 0.80 [95%CI (0.69, 0.91)], 0.72 [95%CI (0.62, 0.81)], and 0.64 [95%CI (0.50, 0.77)], respectively. The consistency index of nomogram was 0.724 [95%CI (0.685, 0.763)], and the calibration curve of the 3-year PFS probability was very close to the ideal diagonal. ConclusionAccording to the preliminary research results of database and clinical case data, RBPs ZFP36 might be a potential prognostic target for patients with PTC.
ObjectiveTo explore the causes and surgical strategies of completion thyroidectomy for thyroid cancer. Method The clinical data of 35 patients with thyroid cancer who underwent completion thyroidectomy in Guizhou Provincial People’s Hospital from January 2020 to July 2022 were analyzed retrospectively. Results There were 23 females and 12 males, aged from 17 to 68 years (median 42 years). The nature of thyroid nodules in 22 patients was not determined at preoperative fine needle aspiration cytology or intraoperative frozen pathological examination, but the paraffin section examination after operation indicated thyroid cancer. Pathological examination after the first operation showed that 11 patients had a large number of lymph node metastasis in the central area (more than 5), and 2 patients were confirmed as medullary thyroid carcinoma. All the 35 patients underwent completion thyroidectomy at 5–93 days after the initial operation, among which 3 patients underwent resection of the affected side residual glandular lobe and isthmus ± ipsilateral CLN dissection, 18 patients underwent contralateral lobectomy and CLN cleaning, and 14 patients underwent contralateral lobectomy and lymph node dissection of the affected side cervical region (Ⅲ–Ⅳ region). The operative time was 45–135 min (median 105 min). Intraoperative blood loss was 10–50 mL (median 20 mL). One patient suffered from temporary recurrent laryngeal nerve injury after operation, and voice had returned to normal at 5 months after operation. Six patients showed temporary hypoparathyroidism, and serum parathyroid hormone returned to normal level in 1–3 months after symptomatic treatment. Nineteen patients were treated with iodine-131 after operation, and were followed-up for 1–16 months (median 12 months). No signs of tumor recurrence or metastasis were found. Conclusions Accurate preoperative and intraoperative evaluation of thyroid nodules and standardized surgery can reduce the incidence of completion thyroidectomy. For patients who really need completion thyroidectomy, adequate doctor-patient communication during the perioperative period, early response measures and appropriate completion thyroidectomy can reduce the probability of postoperative tumor recurrence and improve the survival of patients.
