ABSTRACT
Objective:To investigate the influencing factors of goiter in school-age children aged 8 to 10 in non-high iodine areas of Shijiazhuang City.Methods:In April 2018, 9 non-high iodine counties (cities) were selected as monitoring sites in Shijiazhuang City, and capacity proportional probability sampling (PPS) method was used. Each monitoring site was divided into five sampling areas according to five orientations: east, west, south, north, and middle, one township was selected from each area, one elementary school was selected from each township, and 40 school-age children aged 8 to 10 (balanced age, half males and half females) were selected from each school as respondents. Urine samples from any one time of children and drinking water samples from their village were collected, and urinary iodine and water iodine were detected by arsenic cerium catalytic spectrophotometry; the thyroid volume of children was measured by B ultrasound method; at the same time, the height and weight of children were measured and the body mass index was calculated. The influencing factors of goiter were analyzed by logistic regression analysis.Results:A total of 1 867 urine samples of school-age children were collected, and the median urinary iodine was 190.65 μg/L, which was in the suitable level of iodine. A total of 1 046 drinking water samples were collected, water iodine ranged from 0.11 to 87.91 μg/L, and the median water iodine was 3.01 μg/L. A total of 1 867 school-age children were tested thyroid, the median thyroid volume was 3.01 ml. The medians thyroid volume of boys and girls (928 and 939 cases) were 2.90 and 3.13 ml, respectively, the difference was statistically significant between sex ( U = 2.09, P < 0.05); the medians thyroid volume of children aged 8, 9, and 10 years old (622, 629, 616 cases) were 2.47, 2.87, and 3.13 ml, respectively, the differences were statistically significant among ages ( H = 203.96, P < 0.01); the medians thyroid volume of normal, overweight and obese children (1 231, 300, 336 cases) were 2.61, 3.05 and 3.16 ml, respectively, the differences were statistically significant among body mass index ( H = 65.55, P < 0.01). The results of multifactorial logistic regression analysis showed that female and obesity were risk factors of goiter in school-age children [odds ratio ( OR) = 2.08, 2.86, 95% confidence interval ( CI): 1.05 - 4.12, 1.39 - 5.88, P < 0.05]. Conclusion:Female and obesity are risk factors of goiter in school-age children aged 8 to 10 in non-high iodine areas of Shijiazhuang City.
ABSTRACT
Objective To investigate the therapeutic method of extensive abdominal adhesion and organ edema ("frozen abdomen" status) with severe retroperitoneal infection. Methods The treatment measures, therapeutic course and characteristics of 21 patients with retroperitoneal infection complicated with sepsis under "frozen abdomen" status admitted to Rizhao Hospital of Traditional Chinese Medicine from 2004 to 2017 were retrospectively analyzed, inductive therapeutic measure and characteristics and the clinical efficacy and prognosis were also observed. Results In 21 cases, 19 cases were cured clinically, 1 case died of massive hemorrhage and 1 case died of multiple organ failure (MOF). In the 8 cases, abdominal cavity opening were performed, no exposure of intestinal fistula occurred, although the abdominal wall hernias were left behind in 6 cases and pancreatic pseudo-cyst was formed in 1 case. The patients total time of hospitalization was (61.0±10.5) days, and the stay in Intensive Care Unit (ICU) was (28±5) days. Conclusion In the comprehensive treatments, the multi-form flushing drainages were the core of effective means to control the severe retroperitoneal infection.
ABSTRACT
Objective To explore the iodine status of pregnant women after 17 years of salt iodization in rural areas of Shijiazhuang City.Methods Probability proportionate to size sampling was employed in which 30 towns were selected from the 211 towns in the rural areas of Shijiazhuang City.In each town selected,40 pregnant women were randomly selected to collect their spot urine samples,edible salt samples and drinking water samples from their households to measure iodine content.The iodine content of salt was determined quantitatively using a titration method (GB/F 13025.7-2012).The urinary iodine content was determined using the method of ammonium persulfate digestion arsenic cerium catalytic spectrophotometry (WS/T 107-2006).The iodine content in drinking water was determined by the method of standard test for drinking water.Results A total of 1 200 salt samples was collected from the pregnant women's households in 30 towns,with the overall median iodine content being 27.2 mg/kg.The median salt iodine content in 30 towns varied from 23.4 to 32.6 mg/kg.A total of 478 water samples were collected,with a median of 5.3 μg/L.The median urinary iodine content (UIC) of 1 200 pregnant women in 30 towns was 146.4 μg/L.The median UIC in the first (≤ 13 weeks),second (14 ～ 26 weeks) and third (≥27 weeks) trimesters was 166.3,145.1 and 133.5 μg/L,respectively.The median UIC in the first trimester was significantly higher than that in the third trimester (Mann-Whitney Test,U =18 265,P ＜ 0.05).Except for the 9-20 and 37-40 weeks period of pregnancy,the median UIC was lower than the WHO criteria (150 μg/L).Tested by linear correlation,the pregnant women's median UIC did not correlate with median salt iodine (r =0.725,P ＞ 0.05).Conclusion Under the current universal salt iodization,the pregnant women's iodine intake could almost meet their requirement in the rural areas of Shijiazhuang City,however,mild iodine deficiency has existed in the third trimester.Alternative measures of iodine supplement could be implemented.
