Objective: To investigate the iodine nutrition status of children aged 8-10 in Guangming, Longhua and Yantian District of Shenzhen in 2023, and to explore the influencing factors of thyroid volume. To evaluate prevention strategies and to provide a scientific basis for the elimination of iodine deficiency disorders. Methods: Urine and household salt samples were randomly collected from 580 non-boarding students aged 8-10 years foriodine content detection. Thyroid volume was measured using a fully digital ultrasound imaging system, and goiter prevalence was calculated. Results: A total of 580 samples was tested. The median salt iodine concentration was 23.86 mg/kg, with 93.62% qualified iodized salt and 94.48% coverage rate. The median of urinary iodine was 265.00 μg/L, mainly distributed between 200 - < 300 μg/L and ≥300 μg/L. The proportion of children with ap⁃ propriate iodine was 20. 86% , and the proportion of children with insufficient or excessive urinary iodine levels was 10. 86% and 68. 28% of the total surveyed population , respectively. The median thyroid volume was 3. 27 mL , and the goiter rate was 1. 72% . Multiple linear regression analysis showed that age was the risk factor for thyroid volume (8=0 328, P<0.05). while urinary iodine was the protective factor for thyroid volume(B=-4.134x10-4,P<0.05). Conclusion The qualified iodized salt rate, median of urinary iodine,and goiter prevalence of 580 children aged 8 - 10 meet the elimination criteria for iodine deficiency disorders. Age and urinary iodine are closely related to thyroid volume change. The urinary iodine level of children is generally high and requires serious attention.

Surgery is the important treatment for each type of thyroid cancer. Single or multiple parathyroid injuries or blood supply disorders may occur during the operation, resulting in dramatic decline of parathyroid hormone and hypocalcemia after operation, which is common in clinical practice. After discharge, chronic hypocalcemia can cause great physical and psychological pain to patients. Although the residual parathyroid glands can compensate after surgery in some cases, long-term negative calcium balance and postoperative hypocalcemia may cause excessive hyperplasia of the residual parathyroid glands, resulting in parathyroid hyperfunction or even hyperparathyroidism, which can lead to osteoporosis, urinary calculi, metastatic vascular calcification, and systemic abnormal migratory calcium deposits. It’s advisable to enhance the awareness of the cause and harm of the postoperative hypocalcemia, evaluate and diagnose it early, and actively intervene in every stage of before, during and after the operation and long-term follow-up, which can effectively reduce the occurrence and severity of hypocalcemia and improve the postoperative life quality and the prognosis.

Thyroid cancer is the common malignant tumor in the neck, and surgery is the important treatment measure for it. Some patients suffer from hypoparathyroidism and hypocalcemia after thyroidectomy, which will seriously affect the patient’s life quality and prognosis. This article reported a case of 42 years old female patient with hypocalcemia for 6 years after total thyroidectomy due to thyroid cancer, who still had frequent hypocalcemia with high dose of oral calcium and active vitamin D supplementation. Long-term and frequent facial and limb numbness, convulsions, epileptic-like seizures and sudden unconsciousness afflicted her due to hypocalcemia. After admission, her symptoms were obviously relieved after one week of adequate calcium supplementation through oral administration or intravenous infusion under close monitoring. Upon discharge she was able to maintain the normal level of blood calcium by decreased dose of oral calcium supplementation alone. Long-term limb numbness, convulsions, low back pain, shoulder pain, walking instability and other symptoms disappeared basically. The epileptic-like seizures did not recur. During six months of follow-up, her blood calcium was still well controlled in normal level.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.

OBJECTIVE: To investigate the clinical characteristics and prognostic factors of reoperation patients with postoperative recurrence or metastasis of gastrointestinal stromal tumor (GIST). METHODS: A retrospective case-control study was performed on the clinical data of 31 patients with GIST who had recurrence or metastasis after the first surgery and underwent one or more operations again from February 2003 to January 2016 at Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The clinical characteristics of these patients were analyzed. Kaplan-Meier survival curve was used to calculate the survival rate, Cox univariate and multivariate regression model was applied to prognosis analysis. RESULTS: Age of these 31 patients at the first operation was 35-78 (median 49) years, including 17 males (54.8%) and 14 females (45.2%). The tumors of 21 cases located in small intestines (67.7%), 2 cases in stomach (6.5%), 4 cases (12.9%) in colorectum and of 4 cases (12.9%) in other sites. According to NIH criteria, risk assessment indicated 26 cases were(83.8%) with high risk, 3 cases (9.7%) with moderate risk, and 2 cases (6.5%) with low risk. After the first operation, 15 cases received the IM (imatinib) therapy regularly based on NCCN guideline,10 cases received the therapy irregularly, and the other 6 cases did not receive the therapy. R0 resection was performed in 29 cases (93.5%) and R1/R2 resection was performed in 2 cases (6.5%). The median interval between the first operation to the recurrence was 32.3 (5.2-117.6) months and the median age of recurrence was 56 years old. Refer to the recurrent location, 28 cases (90.3%) were found in the same location or liver, 1 case in greater omentum, and 2 cases in pelvic cavity. The median diameter of the tumor in reoperation was 6.5 cm. Twenty-three cases(74.2%) received R0 excision and the other 8 cases(25.8%) received R1/R2 excision. At diagnosis of tumor recurrence, 20 cases (64.5%) received the second surgery immediately and the other 11 cases received surgery after imatinib or sunitinib treatment. Twenty-nine (93.5%) patients were followed up for 7.3 to 160.3 (median 49.5) months. After the second surgery, the relapse-free survival (RFS) of the whole group was 3.2 to 148.6(median: 29.7) months. Till the end of follow-up, 9 cases died of recurrence. Among 20 alive cases, 8 cases were living with the tumor, 1 case received the third surgery. The median overall survival (OS) time was 38.4(6.2-160.3) months. The 5-year RFS and the 5-year OS of 15 cases who received regular targeted therapy after the first operation were 73.4% and 81.7% respectively, significantly higher than those of the other 16 cases who received irregular or no targeted therapy(37.6%, P=0.015 and 38.9%,P=0.023,respectively). The 5-year RFS rate and the 5-year OS rate of the 11 patients who were diagnosed or complicated with liver metastasis were 29.8% and 32.2% respectively, which were significantly lower than those of the 20 patients without liver metastasis (79.1% and 88.1% respectively, both P<0.001). Cox model for OS, the results showed that regular targeted therapy after first surgery(HR=0.362, 95%CI:0.210-1.074, P=0.089) and the liver metastasis (HR=5.342, 95%CI: 0.902-12.580, P=0.057) were not the independent risk factors. CONCLUSIONS Regular targeted therapy according to the guideline after the first operation for GIST patients with recurrence or metastasis may improve the prognosis. Prognosis of GIST patients with postoperative liver metastasis is poor.

Objective To explore the diagnostic value of the CT angiography (CTA) in the detection of mechanical obstructive cause of deep venous thrombosis of lower extremity. Methods Forty-seven cases of CTA and DSA image data of DVT in lower extremity with mechanical obstruction were retrospectively analyzed. The CTA three-dimensional reconstruction images were compared with DSA results, and the position and size of thrombus, collateral circulation of blood vessels, vascular compression area and the corresponding outside vascular lesions were evaluated. The causes of venous occlusion were analyzed. Diagnostic agreement of CTA and DSA was assessed by Kappa statistics. The difference of the accuracy between CTA and DSA in the diagnosis of the left and right iliac femoral vein, inferior vena cava, internal iliac vein thrombosis were analyzed with χ2 test. Results There were 47 patients with lower extremity DVT. Of them, DVT was detected in the left leg in 28 patients, in the right leg in 14 patients and in both lower extremities in 5 patients. Mechanical obstruction caused DVT in all of them. There were 27 patients of iliac vein compression syndrome(IVCS)complicated with lower limb DVT. The left iliac vein was oppressed by the right common iliac artery with compression degree from 55.41%to 100.00%,and mean of(77.1 ± 16.8)%. There was congenital stenosis or occlusion of inferior vena cava in 3 patients. There was Budd-Chiari syndrome in 2 patients. There was pelvic mass pressing the common iliac vein in 4 patients. Enlarged right inguinal lymph nodes oppressed the right femoral vein in 3 patients and enlarged left inguinal lymph nodes oppressed the left femoral vein in 2 patients. Other mechanical obstruction factors caused DVT in 6 patients, including right iliac artery aneurysms,spontaneous hematoma, etc. The agreement of CTA and DSA on the diagnosis of the iliac femoral thrombosis was good (Kappa=0.978), the diagnosis agreement on the inferior vena cava thrombus was good (Kappa = 0.737), while the diagnosis agreement on the internal iliac vein thrombosis was poor (Kappa=0.189). The difference of CTA and DSA in the diagnosis of left and right iliac femoral venous thrombosis was not statistically significant (52,51 case;χ2=0.00, P>0.05), neither was the diagnostic difference of inferior vena cava thrombus (21,17 cases;χ2=1.50, P>1.50). However, the difference of the diagnosis of the iliac vein thrombosis was statistically significant (14,2 cases;χ2=8.33, P<0.05) . Conclusions CTA can clearly show the location and scope of the thrombus. Compared with conventional DSA, CTA shows higher diagnostic coincidence rate, and can accurately determine the mechanical obstruction causes of lower extremity DVT.
