Objective:To investigate the iodine nutritional status of pregnant women in Qingdao and the effect of prevention and treatment of iodine deficiency disorders (IDD), so as to provide a basis for residents to supplement iodine scientifically, and take targeted prevention measures and adjust intervention strategies.Methods:In accordance with the requirements of the "National Iodine Deficiency Disorders Surveillance Program (2016 edition)" and "Shandong Iodine Deficiency Disorders Surveillance Program", the cluster sampling method was adopted to select pregnant women from 10 districts (cities) in Qingdao from 2018 to 2020, to investigate their basic information and thyroid disease history. Meanwhile, household edible salt samples and random urine samples were collected to detect iodine content.Results:A total of 3 000 pregnant women were monitored from 2018 to 2020, the median age was 31 years, and the median gestational age was 18 weeks. There were significant differences in the distribution of age, gestational age, whether senile puerpera, and pregnancy in different years ( H/χ 2 = 29.35, 81.03, 65.62, 77.34, P < 0.001). The median salt iodine of edible salt ( n = 3 000) and iodized salt ( n = 2 700) in pregnant women's homes were 23.02 and 23.70 mg/kg, respectively. The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt were 89.59% (2 419/2 700), 90.00% (2 700/3 000) and 80.63% (2 419/3 000). The comparison of qualified rate of iodized salt, coverage rate of iodized salt and consumption rate of qualified iodized salt among different years was statistically significant (χ 2 = 48.09, 36.62, 61.08, P < 0.001), the coverage rate of iodized salt and the consumption rate of qualified iodized salt showed a downward trend year by year (χ 2trent = 35.54, 29.50, P < 0.001). A total of 3 000 urine samples were collected from pregnant women and the median urinary iodine of pregnant women was 147.85 μg/L. The urinary iodine level in the third trimester was lower than that in the first and second trimesters ( P < 0.001). The urinary iodine level in the non elderly group was higher than that in the elderly group ( Z = - 6.66, P < 0.001). The urinary iodine level in the group without thyroid disease was higher than that in the group with thyroid disease ( Z = - 1.99, P = 0.047). The urinary iodine level in iodized salt group was higher than that in non-iodized salt group ( Z = - 2.42, P = 0.015). Conclusions:The iodine nutrition of pregnant women in Qingdao is generally at an insufficient level, and the risk of iodine deficiency is high, which needs attention. In recent years, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in Qingdao have shown a downward trend, and have failed to meet the requirements of national standards. In the future, we should strengthen the monitoring and health education of IDD in pregnant women.

Relationship Between Signaling Pathway and Diabetic Retinopathy and Intervention of Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Diabetic retinopathy （DR） is one of the most common chronic microvascular complications of diabetes mellitus. It has a high rate of blindness， and the age of onset is gradually getting younger， which seriously affects the physical and mental health and quality of life of patients. The disease is retinal damage induced by diabetes mellitus， which is a kind of fundus disease with the main manifestations of fundus hemorrhage， hard exudation， microhemangioma， cotton-wool spots， neovascularization， etc. In traditional Chinese medicine （TCM）， it is classified into the category of "diabetic cataracts" and other diseases. At present， there is no effective method to prevent the progress of the disease in modern medicine， so it is particularly important to choose a reasonable and effective intervention to prevent and treat DR. Studies have confirmed that TCM has unique advantages in the treatment of DR. It can use its advantages of multiple bioactive components， multiple targets， and multiple pathways to intervene in the development process of DR from various aspects. By searching for the relevant literature on the progress of the intervention of DR with TCM monomers and compounds， this paper mainly reviews the relevant research results of the treatment of DR with multiple signaling pathways such as phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor kappa-B（NF-κB）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor erythroid 2-related factor （Nrf2）/hemeoxygenase-1 （HO-1）， Hippo， advanced glycation end products （AGEs）/receptor for advanced glycation end products （RAGE）， and Akt/glycogen synthase kinase-3β （GSK-3β）， so as to provide more ideas and directions for the clinical prevention and treatment of DR.

Objective:To investigate the iodine nutritional status of children in Qingdao City and the effects of prevention and treatment measures on iodine deficiency disorders (IDD), and to provide a scientific basis for guiding residents to scientifically supplement iodine, taking timely targeted prevention and control measures, and scientifically adjusting intervention strategies.Methods:According to "National Iodine Deficiency Disorders Surveillance Program (2016 edition)" and "Iodine Deficiency Disorders Surveillance Program of Shandong Province", from 2018 to 2020, using the cluster sampling method, children aged 8-10 years in Qingdao City were chosen to test their household salt iodine content and random urinary iodine content, and to examine their thyroid volume by B-ultrasonography, and the correlation between thyroid volume and physical development indexes was analyzed.Results:From 2018 to 2020, a total of 6 057 children were monitored, including 3 068 boys and 2 989 girls. The median of salt iodine and iodized salt iodine of children was 23.50 and 24.10 mg/kg. The qualified rate of iodized salt was 89.95% (4 832/5 372), the coverage rate of iodized salt was 88.69% (5 372/6 057), and the consumption rate of qualified iodized salt was 79.78% (4 832/6 057). There were significant differences in the qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt between different years (χ 2 = 135.26, 314.71, 342.87, P < 0.001). A total of 6 057 urine samples were collected from children, and the median of urinary iodine was 193.92 μg/L, of which 16.2% (979/6 057) were < 100 μg/L, and 22.5% (1 361/6 057) were ≥300 μg/L. There were statistically significant differences in the medians of urinary iodine between different years, gender and whether eating iodized salt ( H/Z = 37.25,-3.89,-5.69, P < 0.001), the median of urinary iodine in boys was higher than that of girls, and the median of urinary iodine in eating iodized salt group was higher than that of eating non-iodized salt group. There was no significant difference in the median of urinary iodine between different age ( H = 4.33, P = 0.119). The rate of goiter in children was 3.45% (71/2 057), and the difference between different years was statistically significant (χ 2 = 42.68, P < 0.001). The incidence of goiter in 2020 [7.31% (45/616)] was significantly higher than that in 2018 and 2019 [2.81% (18/641), 1.00% (8/800), P < 0.001]. Thyroid volume of children was positively correlated with height and weight ( r = 0.20, 0.22, P < 0.001). Conclusions:The iodine nutritional level of children aged 8-10 years in Qingdao City is appropriate. However, the incidence of goiter in children in some years is relatively high. The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt are all lower than the national standard for elimination of IDD, which should be paid attention to.
