Objective:To understand the applicability of different thyroid volume correction methods for school-age children in Wuhan, and to explore the appropriate thyroid volume correction methods for school-age children in Wuhan.Methods:From May to August 2019, Hongshan, Hanyang, Hannan, Jiangxia and Dongxihu districts of Wuhan were divided into five sampling areas according to five directions: east, west, south, north and middle. One primary school was selected from each area, and 40 non-boarding students aged 8 - 10 years old (gender balanced) were selected from each primary school as survey subjects. Random urine sample and household edible salt sample were collected to detect urinary iodine and salt iodine contents, and the height, weight and thyroid volume of the children were measured. At the same time, the thyroid volume was corrected by height corrected volume index 1 (HVI1), weight and height corrected volume index (WHVI), body mass index corrected volume (BMIV), body surface area corrected volume (BSAV) and height corrected volume index 2 (HVI2).Results:A total of 1 000 children aged 8- 10 years old were investigated, including 499 boys and 501 girls; among them, there were 269, 321 and 410 children aged 8, 9 and 10 years old, respectively. The median urinary iodine was 247.50 μg/L; the median salt iodine was 23.20 mg/kg; the height, weight and thyroid volume were 140.00 (133.00, 146.00) cm, 31.00 (27.00, 37.00) kg and 2.56 (2.13, 3.21) ml, respectively. A total of 30 children with goiter were detected, and the goiter rate was 3% (30/1 000). The thyroid volumes of boys and girls were 2.57 (2.16, 3.28) and 2.56 (2.10, 3.16) ml, respectively, and the difference was not statistically significant ( U = - 0.981, P > 0.05). The thyroid volumes of children aged 8, 9 and 10 years old were 2.31 (1.98, 2.81), 2.68 (2.13, 3.30) and 2.74 (2.28, 3.35) ml, respectively, and the differences were statistically significant ( H = 47.585, P < 0.01). Spearman correlation analysis showed that the original thyroid volume was positively correlated with height and weight in children aged 8, 9 and 10 years old ( P < 0.01). After HVI1 correction, no correlation was found between thyroid volume and height in children aged 8 years old ( P > 0.05), but thyroid volume was positively correlated with weight ( P < 0.01); thyroid volume was positively correlated with height and weight in children aged 9 and 10 years old ( P < 0.01). After WHVI correction, the thyroid volumes of children aged 8, 9, and 10 years old were negatively correlated with height and weight ( P < 0.01). After BMIV correction, the thyroid volume was positively correlated with height in children aged 8, 9, and 10 years old ( P < 0.01); thyroid volume was negatively correlated with weight in children aged 10 years old ( P < 0.05). After BSAV correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.05). After HVI2 correction, thyroid volume was positively correlated with weight in children aged 9 years old ( P < 0.01). The thyroid volume obtained by the 5 correction methods were all smaller than the original thyroid volume, and the thyroid volume after BSAV correction was the closest to the original thyroid volume, with a difference of 0.87% - 13.87%. Conclusions:The thyroid volume of school-age children in Wuhan is affected by age, height, and weight, judgment of goiter should be corrected for these factors. BSAV is relatively independent and stable, it can eliminate the effect of height and weight on thyroid volume. It is initially considered that BSAV is suitable for the correction of thyroid volume in school-age children in Wuhan.

Objective:To retrospectively analyze the survival outcomes of the surgical management of primary small cell carcino-ma of the esophagus. Methods:The medical records were reviewed for patients diagnosed with esophageal carcinoma and underwent esophagectomy from January 2000 to December 2009 at the Department of Thoracic Surgery of the Henan Cancer Hospital. We fo-cused on the clinical data of patients with small cell carcinoma of the esophagus. The Kaplan-Meier approach with log-rank test was used for survival analysis. Results:A total of 5,062 patients underwent esophagectomy with curative intent at the Department of Thorac-ic Surgery of the Henan Cancer Hospital;among which, 57 (1.1%) were diagnosed with small cell carcinoma of esophagus. The most common surgical approach was trans-left thoracic incision esophagectomy. Cervical esophagogastrostomy was performed for all pa-tients. The most common chemotherapy regimen was EP. The overall 5-year survival rate was 12.5%, and the median survival time was 45 months. Among the various stages, the 5-year survival rate and survival time were 25% and 50 months for Stage I, 5.9% and 43 months for Stage II, and 4.3%and 43 months for StageⅢ. Subgroup analysis showed that cases treated with surgery alone had poorer overall median survival time compared with those cases that underwent surgery plus chemotherapy (23.2 months vs. 60.7 months, re-spectively;P<0.01). Even for Stage I patients, thesurgery plus chemotherapysubgroup was associated with a significantly longer me-dian survival time than the surgery alone subgroup (81.9 months vs. 22.3 months, P<0.01). Conclusion:For patients with primary small cell carcinoma of the esophagus, surgery alone cannot provide the optimal prognosis. Surgery combined with systemic chemother-apy can improve the survival time.

Background and purpose: Sorafenib hepatocellular carcinoma assessment randomized protocol (SHARP) and sorafenib in patients in Asia-Pacific region with hepatocellular carcinoma (ORIENTAL) had indicated that multi-kinase inhibitor sorafenib could prolong overall survival (OS) and time to progression (TTP) as well as improve progress free survival (PFS) in patients with advanced stage hepatocellular carcinoma. Drug-related adverse events in the course of treatment restricted its clinical application to a certain degree. This study was aimed to summerize the adverse events as well as the management of sorafenib in our clinic. Methods: Twenty-five cases clinically diagnosed as advanced hepatocellular carcinoma were enrolled from January 2008 to October 2009. All the patients who received sorafenib treatment met inclusion criteria as followed: (1) Progression of disease after trans-hepatic arterial chemoembolization therapy; (2) Extensive portal vein cancerous thrombus formation; (3) Portal zone or retroperitoneal lymph node metastasis or multiple remote metastasis, such as lung or bone; (4) Diffused poor blood supply to tumor; (5) Inform consent was obtained. All adverse events with different grade were observed during the beginning 12 weeks, and clinical treatment were carried out relatively. Results: Total of 25 cases were enrolled. Nine patients died of the disease, 3 of them died during the first 12 weeks, 3 patients abandoned sorafenib treatment, among them 2 died before the finish of 12 weeks treatment and 1 patient discontinued 5 months after the sorafenib treatment. Twenty cases finally assigned. Number of patients encountered drug-related adverse events were: HFSR (hand-foot-skin-reaction) 4(4/20), diarrhea 4(4/20), alopecia 5(5/20), rasb 4(4/20), fatigue 8(8/20), leukopenia and Thrombocytopenia 4(4/20), elevated blood pressure 1(1/20) and abdominal pain 1(1/20). After clinical management, 20 patients' sorafenib treatment were eventually not affected by adverse events. Conclusion: Sorafenib was well-tolerated and is a safe option of treatment for patients with advanced hepatocellular carcinoma.

This study described the radiological features on echocardiography and MRI specific to cardiac amyloidosis confirmed on biopsy. Eleven cases of biopsy-proven cardiac amyloidosis were retrospectively reviewed in this study. All patients underwent biopsy, cardiac MRI and echocardiography. The main echocardiography and MRI findings were as follows: diffuse ventricular and septum wall thickening, atrial enlargement, pericardial effusion, restricted left ventricular (LV) systolic and diastolic function, characteristic granular sparkling of myocardium. MRI revealed a characteristic pattern of global subendocardial late enhancement, extending in varying degrees into the neighboring myocardium. The findings agreed with the infiltration distribution of amyloid protein. Typical abnormalities seen on echocardiography and MRI should have important diagnostic and prognostic value of cardiac amyloidosis. MRI should be considered in the diagnosis of cardiac amyloidosis if echocardiographic features are suspicious.
