Objective To investigate the iodine nutrition level of vulnerable people in Inner Mongolia after adjustment of iodized salt standard and to provide theoretical bases for scientific iodine supplementation. Methods In 2013, 3 cities were selected from eastern, central and western parts of Inner Mongolia in accordance with the random number table, 3 or 4 counties were selected from each target city, 5 units according to their sub-area position of east, south, west, north and center were selected from each county, and then 1 township was selected from each unit, 5 groups of target population including school children aged 8- 10, women of childbearing age, pregnant and lactating women and infants each at least 10 people were investigated in each township. Edible salt samples from their homes and urine samples were collected. The direct titration method among the generic methods of iodide testing for salt production industry (GB/T 13025.7-2012) was used to determine the salt iodine level, and As3+-Ce4+catalytic spectrophotometry using ammonium per sulfate digestion (WS/T 107-2009) was used to test the urinary iodine level. Results Totally 3 300 samples of edible salt from local residents had been examined and median iodine was 26.20 mg/kg. The median of urinary iodine was 190.6μg/L of 1 289 school-age children;was 183.6μg/L of 621 women of childbearing age; was 178.2 μg/L o f 876 pregnant women; was 178.6 μg/L of 664 lactating women and was 167.7μg/L of 599 infants. Conclusion After adjustment of iodized salt standard, iodine nutrition level is suitable in all vulnerable people.

Objective Explore the difference of water channel protein 4 (AQP4) 's expression level in different grade glioma tissues.Methods select 57 cases of paraffin embedding glioma tissues and 10 cases of normal brain tissue in our hospital from 2008 to 2012,use immunohistochemical method to test the level of AQP4 and do statistical tests.Results The AQP4 expression level in high grade glioma tumor tissues is higher than in the low grade glioma and normal brain tissue (P ＜ 0.05),and there is no statistical significance about the difference AQP4 expression levels between low grade glioma tumor tissue and normal brain tissue (P ＞ 0.05).Conclusions AQP4 expression level in glioma is closely related to the tumor pathological level.

Objective To investigate the influence of the serum vascular endothelial growth factor (VEGF) in the glioma patients by the malignant degress.Methods Quantitative analysis the serum VEGF levels with the double antibody sandwich assay (ELISA) for 35 cases of glioma patients and 10 cases of healthy human and analyze the correlation of them.Results Mean serum VEGF expression in glioma patients was 120.71 ±45.99 pg/ml,normal value of the healthy people was 63.70 ± 6.50,the difference was statistically significant (P ＜0.05); serum VEGF expression was 156.43 ± 14.90 pg/ml in high-grade glioma patients (Ⅲ-Ⅳ grade) and 67.14 ± 6.12 pg/ml in low-grade glioma patients (Ⅰ-Ⅱ grade),the difference was statistically significant (P ＜ 0.05) ; there' s no different from low-grade glioma patients (Ⅰ-Ⅱ grade) and nomal(P ＞ 0.05).Conclusion The serum VEGF levels in the glioma patients was influence by the malignant degress.

Objective:To explore the prevalence and risk factors of thyroid diseases in the physical examination population of Hohhot.Methods:From July 2017 to July 2018, 3 100 health examinees from Inner Mongolia National Examination Medical Center were selected as subjects for questionnaire survey, thyroid function test and thyroid ultrasound examination; a multinomial logistic regression model was used to analyze the relationship between relevant investigation factors and different types of thyroid diseases (simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules).Results:Among the 3 100 healthy examinees, there were 2 885 effective responders, including 743 males and 2 142 females, aged (46.23 ± 12.32) years; the simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules were 909, 648, and 619 cases, respectively, and the detection rates were 31.51%, 22.46%, and 21.46%, respectively. Logistic regression analysis results showed that age [35 - 54 years old: odds ratio ( OR) = 1.30, 95% confidence interval ( CI): 1.01 - 1.68; ≥55 years old: OR = 2.30, 95% CI: 1.68 - 3.14, P < 0.05], gender ( OR = 1.65, 95% CI: 1.32 - 2.07, P < 0.05), obesity ( OR = 1.35, 95% CI: 1.08 - 1.70, P < 0.05), and mental stress [significant: OR = 1.64, 95% CI: 1.09 - 2.48; some: OR = 1.54, 95% CI: 1.02 - 2.32, P < 0.05] were the risk factors affecting the occurrence of simple thyroid nodules. The age (35 ~ 54, ≥55 years old), gender, bad mood (a little), and mental stress (significant) were risk factors that affected the occurrence of simple thyroid dysfunction; eating high iodine food was its protective factor. The age (35 ~ 54, ≥55 years old), gender, obesity, and thyroid family genetic history were risk factors for thyroid dysfunction with nodules; the consumption of iodized salt was its protective factor. Conclusions:Older women are high-risk groups for thyroid diseases. Obesity, bad mood, mental stress will increase the risk of the disease. Daily consumption of iodized salt and moderate consumption of high iodine food can reduce the risk of the disease.
