ABSTRACT

Objective:To discuss the comprehensive evaluation of the effectiveness of iodine deficiency disorders prevention and control in Xinjiang Production and Construction Corps (Corps for short) using technique for order preference by similarity to an ideal solution (TOPSIS) and rank-sum ratio (RSR) methods, and identify weaknesses in the prevention and control of iodine deficiency disorders in the Corps at present.Methods:The monitoring data on iodine deficiency disorders in the Corps from 2014 to 2020 were collected from the Disease Control and Prevention Center of the Corps. Six indexes were selected, including the consumption rate of qualified iodized salt, the coverage rate of iodized salt, the qualified rate of iodized salt, the appropriate percentage of urinary iodine in children, the goiter rate of children and the appropriate percentage of urinary iodine in pregnant women. The TOPSIS method and RSR method were combined to comprehensively evaluate the prevention and control effect of iodine deficiency disorders in the Corps.Results:The results of TOPSIS method showed that the control effect was from superior to inferior in the order of 2020, 2018, 2016, 2019, 2015, 2017 and 2014. Based on the RSR method, the control effect was divided into three levels: 2018 and 2020 (with an estimated RSR value of ≥0.525) in the first level (good), 2014 (estimated RSR value < 0.007) in the third level (poor), and other years (0.007≤estimated RSR value < 0.525) in the second level (medium). Referring to the monitoring data, the appropriate percentage of urinary iodine in children and pregnant women in the middle years was the weak point. Conclusions:TOPSIS method combined with RSR method can accurately and reasonably evaluate the effectiveness of prevention and control of iodine deficiency disorders in the Corps, the evaluation results are consistent with the actual situation. It is found that the appropriate iodine nutrition levels of children and pregnant women are the weak points in the prevention and control of iodine deficiency disorders in the Corps.

ABSTRACT

Objective:To fully learn about the iodine nutrition level and the status quo of prevention and control of iodine deficiency disorders (IDD) among children aged 8 - 10 years and pregnant women in Southern and Northern Xinjiang of Xinjiang Production and Construction Corps (hereinafter referred to as the Corps), and to provide a basis for consolidating the prevention and control effect of IDD and proposing sustainable prevention and control strategies.Methods:From May to November 2020, IDD monitoring was carried out within the Corps. ⑴Salt iodine monitoring: in 14 divisions of the Corps, 1 regiment was selected in each division from five directions of East, West, South, North and Middle, and 4 companies were selected from each regiment and edible salt samples were collected from the homes of 15 Corps employees to test for salt iodine. ⑵Monitoring of urinary iodine and goiter: in 13 divisions of the Corps, 1 regiment was selected from each division according to five directions of East, West, South, North and Middle, and 40 children aged 8 - 10 years (age balanced, half male and female) from one primary school and 20 pregnant women were selected as the survey subjects. Once random urine sample was collected from children and pregnant women to detect urinary iodine; the thyroid volume of children was measured and the goiter rate was calculated.Results:⑴A total of 4 149 salt samples were tested, the median salt iodine was 27.3 mg/kg, the coverage rate of iodized salt was 99.9% (4 146/4 149), the qualified rate of iodized salt was 98.1% (4 069/4 146), and the consumption rate of qualified iodized salt was 98.1% (4 069/4 149). Among them, 1 197 and 2 952 salt samples were tested in Southern and Northern Xinjiang of the Corps, the median salt iodine was 26.7 and 27.5 mg/kg, respectively; the coverage rate of iodized salt was 99.7% (1 194/1 197) and 100.0% (2 952/2 952), respectively; the qualified rate of iodized salt was 95.0% (1 134/1 194) and 99.4% (2 935/2 952), respectively; the consumption rate of qualified iodized salt was 94.7% (1 134/1 197) and 99.4% (2 935/2 952), respectively; and the differences between regions were statistically significant ( P < 0.05). ⑵A total of 2 602 urine samples of children aged 8 - 10 years were detected, and the median urinary iodine was 186.5 μg/L; the median urinary iodine of children (800 and 1 802) in Southern and Northern Xinjiang of the Corps was 181.9 and 188.5 μg/L, respectively. A total of 1 247 urine samples of pregnant women were detected, and the median urinary iodine was 192.6 μg/L; the median urinary iodine of pregnant women (397 and 850) in Southern and Northern Xinjiang of the Corps was 182.2 and 200.3 μg/L, respectively. ⑶A total of 2 602 children aged 8 - 10 years were examined for thyroid volume, and the goiter rate was 1.2% (31/2 602); the goiter rate of children in Southern and Northern Xinjiang of the Corps was 1.4% (11/800) and 1.1% (20/1 802), respectively. Conclusion:In 2020, the Corps has reached the elimination standard of IDD by divisions, and children aged 8 - 10 years and pregnant women are generally at an appropriate iodine level.

ABSTRACT

Objective:To understand the iodine content of edible salt in residents of Xinjiang Production and Construction Corps (referred to as Corps), and provide scientific evidence for prevention and treatment of iodine deficiency disorders.Methods:According to the requirements of the "National Iodine Deficiency Disorders Surveillance Program" form 2015 to 2019, in accordance with the principle of random sampling, one regiment from each of the five directions of east, west, south, north and center in the Corps was selected, and four companies were selected from each regiment. Edible salt samples from the homes of 15 residents in each company were collected, and salt iodine content was quantitatively tested and the test results were analyzed.Results:From 2015 to 2019, 21 028 household salt samples were collected, qualified iodized salt were 20 204, non-qualified iodized salt were 712, non-iodized salt were 112, iodized salt coverage rate was 99.47% (20 916/21 028), iodized salt qualified rate was 96.60% (20 204/20 916), qualified iodized salt consumption rate was 96.08% (20 204/21 028). The average salt iodine content was (27.72 ± 4.81) mg/kg. From 2015 to 2019, the iodized salt coverage rates in the whole Corps were all > 95%, and the iodized salt qualified rates and the qualified iodized salt consumption rate were all > 90%. Among the 14 divisions of the Corps, iodized salt coverage rates were all > 95%, except for the 12th and 14th divisions, where the iodized salt qualified rates and qualified iodized salt consumption rates were < 90%, all other divisions were > 90%.Conclusions:Iodized salt coverage rate, iodized salt qualified rate and qualified iodized salt consumption rate have all reached the national standard for eliminating iodine deficiency disorders from 2015 to 2019, however, non-iodized salt exists in some areas, and the qualified iodized salt consumption rate is low. We should strengthen monitoring of iodized salt in key areas and promote health education, consolidate and maintain achievements in eliminating iodine deficiency disorders.

ABSTRACT

Objective To study the relationship of apoptosis-related gene Survivin with Bcl-2,Bax protein in adenomyosis.Methods The expressions of Survivin,Bcl-2 and Bax protein were deteeted by immunohistochemical method(SP)in ectopic and eutopic endometrium of adenomyosis from 46 cases,and compared with that in eutopic endometrium from endometrium 30 cases without adenomyosis.Results The expression rate of Survivin protein in ectopic endometrium of adenomyosis was much higher than that in normal endometrial cells.The Survivin was positively corelated to Bcl-2,negatively to Bax.Conclusion Survivin may play an important role in pathogenesis of adenomyosis.With Survivin gene,apoptosis-related gene Bcl-2 may have a synergic role and Bax have an antagonistic role in the formation and progression of adenomyosis.
