Objective:To understand the level of iodine nutrition in the areas with iodine deficiency and high iodine in Anyang City of Henan Province, and to provide a basis for taking targeted prevention and treatment measures and scientific adjustment of intervention strategies.Methods:In 2019, three areas with iodine deficiency (median iodine in water < 10 μg/L) and three areas with high water iodine (median iodine in water > 100 μg/L) were selected from counties (cities and districts) in Anyang City by stratified random sampling. Children aged 8-10 and pregnant women were selected in areas with high iodine and areas with iodine deficiency, respectively. Urine samples and salt samples were collected and tested, and children's thyroids were examined by B-mode ultrasound.Results:A total of 654 salt samples were collected in iodine deficiency areas, among which non-iodized salt accounted for 1.83% (12/654). A total of 628 salt samples were collected from areas with high iodine, among which non-iodized salt accounted for 6.05% (38/628). The difference in non-iodized salt rate between the two areas was statistically significant (χ 2=15.19, P < 0.05). A total of 654 urine samples were collected from children in iodine deficiency areas, with a median of 211.15 μg/L of urinary iodine, and 628 urine samples were collected from high iodine areas, with a median of 390.50 μg/L of urinary iodine. The difference was statistically significant ( U=- 18.34, P < 0.05). A total of 300 urine samples were collected from pregnant women in iodine deficiency areas, with a median of 223.95 μg/L, and 127 urine samples were collected from pregnant women in high iodine areas, with a median of 258.00 μg/L. The difference was statistically significant ( U=- 4.07, P < 0.05). The thyroid volume of 560 children in the iodine deficient areas was detected, and the swelling rate was 1.43% (8/560). The thyroid volume of 628 children in high iodine areas was detected, and the swelling rate was 2.07% (13/628). Conclusion:The iodine nutrition level of the population in the iodine deficiency areas of Anyang City is appropriate, while the iodine nutrition level of the population in the water source high iodine areas is excessive.

BACKGROUNDImmunocytochemistry is valuabale in differentiating malignant fluids from benign ones. However, the diagnostic value of a single tumor marker is limited. The aim of this study is to evaluate the clinical value of capture of cancer cells in pleural fluids of patients with lung cancer by cytochip.
METHODSA new pattern cytochip was developed to immunize hybridization of cells in pleural fluids of patients with 42 lung cancers and with 20 lung benign lesions. Ten antibodies were fixed on the cytochip, they were epithelial specific antigen (ESA), CD44V6, ND-1, T cell (CD3), CD45RO, B cell (CD20), CD79a, Hodgkin's cell (CD15), CD30 and macrophage (CD68).
RESULTSThe point of positive hybridization showed round distribution with clear border, and the shape of cell displayed well. The positive numbers of ESA, CD44V6, ND-1 were 35, 30, 38 respectively in pleural fluids of 42 patients with luog cancers; lymphocytes and neutrophils were found on the 1 ESA and 1 ND-1 respectively, and only lymphocytes were found on the 3 CD44V6 in 20 ones with lung benign lesions; the other 7 antibodies did not capture cancer cells except for lymphocytes, neutrophils and macrophages from two pleural fluids.
CONCLUSIONSThe cytochip could be an important practical foreground in clinic for diagnosing cancer cells in pleural fluids of patients with lung cancer.
