Objective:To investigate the effect of 25 hydroxyvitamin D [25 (OH) D] on postoperative parathyroid function in patients with papillary thyroid carcinoma (PTC) .Methods:426 patients who diagnosed as PTC and underwent at least total thyroidectomy plus central lymph node dissection (including lateral lymph node dissection) in Center of Thyroid and Parathyroid Surgery of West China Hospital, Sichuan University, from Jun. 2017 to Sep. 2019 were retrospectively analyzed. Among them, 313 were women and 113 were men, they were divided into vitamin D deficient (VDD) group ( n=297) and normal group ( n=129) according to preoperative 25 (OH) D levels ≤ 20ng/ml and > 20ng/ml. SPSS 23.0 statistical software was used for data processing. Pearson χ2 test or Fisher exact test were used to compare the incidence of clinical hypoparathyroidism, biochemical temporary and biochemical permanent hypoparathyroidism between the two groups. Univariate and multivariate logistic regression analysis were used to analyze the related factors of postoperative hypoparathyroidism between the two groups. Results:Preoperative 25 (OH) D level was significantly correlated with postoperative biochemical temporary hypoparathyroidism ( P=0.04, OR=1.11) . Compared with patients with adequate preoperative vitamin D, preoperative vitamin D deficiency increased the risk of biochemical transient hypoparathyroidism by 6.67 times ( P=0.03;OR=6.67) . There was no significant correlation between preoperative vitamin D deficiency and early postoperative clinical hypoparathyroidism (2.7% vs 3.9%, P=0.55) . Conclusion:Correction of vitamin D deficiency before operation may reduce the incidence of postoperative temporary hypoparathyroidism caused by 25 (OH) D deficiency.

Objective:To study the use of radioactive I-125 seed implantation in the treatment of transarterial chemoembolization (TACE)-refractory hepatocellular carcinoma (HCC).Methods:A retrospective study was conducted on 70 patients with HCC who were initially treated with TACE between July 1, 2016 and August 31, 2019 at the Second Affiliated Hospital of Guangzhou Medical University. After these patients were found to be refractory to TACE, 29 patients were converted to radioactive I-125 seed implantation (the 125I seed group), and 41 patients were continued with TACE (the TACE group). The objective response rate, progression-free survival (PFS), overall survival (OS), total overall survival (TOS) of the two groups were compared. Results:There were 59 males and 11 females, aged (60.5±11.9 ) years in this study. At 1, 3, 6 months after treatment, the objective response rates of the 125I seed group were 20.7%, 40.7%, 34.6%, respectively, which were significantly higher than that of the TACE group of 2.6%, 3.3%, 5.0%, respectively. The PFS, OS, TOS in the 125I seed group were 7.6, 21.1, 32.1 months, respectively, which were significantly better when compared with the TACE group (3.5, 8.5, 14.8 months, respectively, all P<0.05). There was no significant difference in the embolization syndrome between the two groups [93.1%(27/29) vs 100.0%(41/41), P>0.05]. Child-Pugh B grading ( HR=0.311, 95% CI: 0.160-0.603, P=0.005) and TACE ( HR=0.308, 95% CI: 0.159-0.597, P=0.002) were independent risk prognostic factors for survival. Conclusion:This study showed better treatment efficacy and safety using radioactive I-125 seed implantation in TACE-refractory HCC and this treatment significantly improved survival of patients when compared with TACE alone.

Objective:To examine the correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis.Methods:The clinical data of patients with unilateral papillary thyroid carcinoma who underwent total thyroidectomy and bilateral central lymph node dissection and ipsilateral cervical lymph node dissection from June 2016 to June 2018 at Department of Thyroid Surgery, West China Hospital, Sichuan University were analyzed retrospectively. A total of 317 patients, including 87 males and 230 females, aged (41.4±12.1) years (range: 16 to 75 years), were enrolled in this study. The risk factors of contralateral central lymph node metastasis were analyzed by χ 2 test and Spearman correlation analysis. Results:There were 116, 69, 269, and 181 cases of pretracheal lymph node, prelaryngeal lymph node, ipsilateral central lymph node and contralateral central lymph node metastasis, respectively, and 16 cases of skipping metastasis. Univariate analysis showed that contralateral central lymph node metastasis was associated with gender, maximum tumor diameter, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, and ipsilateral central lymph node metastasis (all P<0.05). Spearman correlation analysis showed that male ( r s=0.162, P=0.004), maximum tumor diameter>10 mm ( r s=0.184, P=0.001), capsule invasion ( r s=0.135, P=0.016), pretracheal lymph node metastasis ( r s=0.394, P<0.01), prelaryngeal lymph node metastasis ( r s=0.272, P<0.01) and ipsilateral central lymph node metastasis ( r s=0.203, P<0.01) were independent correlation factors for contralateral central lymph node metastasis. Conclusion:For patients with unilateral papillary thyroid carcinoma with ipsilateral cervical lymph node metastasis, bilateral central lymph node dissection should be considered if male, tumor diameter>10 mm, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, or ipsilateral central lymph node metastasis.

Hypoparathyroidism is one of the most common complications of thyroid surgery. Permanent hypoparathyroidism would bring great pain to patients, seriously affect the postoperative quality of life, is becoming the source of medical disputes. Parathyroid autotransplantation can effectively reduce the incidence of postoperative permanent hypoparathyroidism. However, there are still some dispute about the choice, including the time, the number, the method and the location of parathyroid autotransplantation, which need to be further researched. As a result, the program and survival rate of parathyroid autotransplantation will be optimized and improved, respectively.

Objective To investigate the risk factors of hypoparathyroidism after total thyroidectomy and bilateral central lymph node dissection in patients with papillary thyroid carcinoma.Methods Data of patients with PTC who accepted total thyroidectomy and bilateral central lymph node dissection in the Department of Thyroid Surgery from Jan.2013 to Jun.2016 were collected and analyzed retrospectively.The patients were divided into normal group,transient hypoparathyroidism group and permanent hypoparathyroidism group according to the level of serum parathyroid hormone within 6 months after surgery.Clinical data were collected for comparison between the three groups.The risk factors of hypoparathyroidism were indentified with univariate analysis and multivariate analysis.Results A total of 468 patients,241 in the normal group and 227 in the hypoparathyroidism group (220 in the transient hypoparathyroidism group and 7 in the permanent hypoparathyroidism group),were included in the study.Univariate analysis showed that without application of carbon nanoparticles (P=0.04) and autotransplantation of more than one parathyroid gland (P＜0.001) were risk factors of hypoparathyroidism,and without application of carbon nanoparticles (P=0.047),incidental parathyroidectomy of one parathyroid gland (P=0.04),gross extrathyroidal extension (P=0.006) and c N1a were risk factors of permanent hypoparathyroidism.Multivariate analysis showed that without application of carbon nanoparticles (OR,0.437;95％ CI,0.243-0.789;P=0.006) and autotransplantation of more than one parathyroid gland (OR,3.025;95％ CI,1999-4579;,P=0.000) were independent risk fact ors of hypoparathyroidism,and without application of carbon nanoparticles (OR,0.197;95％ CI,0.039-0.982;P=0.048) and gross extrathyroidal extension (OR,12.381;95％ CI,1.432-107.036;P=0.022) were independent risk factors of permanent hypoparathyroidism.Conclusion When total thyroidectomy and bilateral central lymph nodes dissection were performed,carbon nanoparticles were routinely applied.Although autotransplantation of more than one parathyroid gland can increase the incidence of transient hypoparathyroidism,it can reduce the incidence of permanent hypoparathyroidism.If extrathyroidal extension is suspected,hypoparathyroidism should be emphasized to patient,and accurate operation should be done to reduce the incidence of hypoparathyroidism.

OBJECTIVE: To examine the psychometric features of the body image after breast cancer questionnaire-Chinese version (BIBCQ-C) in Chinese women with breast cancer. METHODS: A total of 545 women with breast cancer received a demographics investigation: BIBCQ-C and hospital anxiety and depression scale (HAD). Four weeks later, 31 patients were selected randomly to finish BIBCQ-C again. RESULTS: The Cronbach's alpha coefficient for the total scale was 0.90, and that for the 6 factors ranged from 0.62 to 0.87. The mean inter-item correlation coefficient of the total scale was 0.16, and the mean inter-item correlation coefficient of the subscales ranged from 0.21 to 0.57, and the test-retest reliability of the total scale and 6 factors was over 0.60. The confirmatory factor analyses supported the 6-factor model, and BIBCQ-C were significantly correlated with the symptom scales of anxiety and depression (r=0.20, 0.21, P<0.01). CONCLUSION BIBCQ-C is reliable and valid, which can effectively assess body image of Chinese women with breast cancer.

PURPOSE: The aim of this study is to explore signal transducer and activator of transcription 3 (STAT3) expression in breast cancer and to analyze the detailed mechanism that STAT3 contributes to the progression of breast cancer. METHODS: We retrospectively analyzed the clinicopathologic characteristics and overall survival (OS) of 140 breast cancer patients after curative surgery, and detected STAT3 expression, phosphorylated STAT3 (pSTAT3) expression, Ki-67 expression, vascular endothelial growth factor (VEGF)-C and -D expression in breast cancer tissues, and adjacent nontumor tissues. Survival analysis and relationship analysis were adopted for demonstrated the important mechanism of STAT3 contribution to progression of breast cancer. RESULTS: STAT3 expression, pSTAT3 expression, Ki-67 expression, VEGF-C expression, and VEGF-D expression in breast cancer tissues were significantly higher than those in adjacent nontumor tissues, respectively. With survival analysis, only number of lymph node metastasis (N stage) was identified as the independent predictors of the OS of breast cancer patients. Besides, we demonstrated there was the most prominent correlation between STAT3 expression and lymph node metastasis in breast cancer tissues by using the multinominal regression method. CONCLUSION: STAT3, a poor survival biomarker potential association with lymph node metastasis, was suitable for predication the OS of breast cancer patients after curative resection.
