Abstract
Long noncoding RNA (lncRNA) is closely related to the pathogenesis of cancer,representing a burgeoning field in tumor research in recent years. MAGI2-AS3, a tumor-associated lncRNA, exerts pivotal roles in epigenetics, transcription and post-transcriptional regulation. Studies have suggested that MAGI2-AS3 may be involved in multiple stages of tumor development, and has potential applications for tumor diagnosis, therapy and prognosis. This review summarizes the expression, regulatory mechanism and clinical application value of MAGI2-AS3 in common malignant tumrs, providing the reference for tumor prevention and treatment.

Objective To evaluate the prognostic value of blood lactate (Lac) level in sepsis patients with or without diabetes.Methods 106 patients admitted to intensive care unit (ICU) of Zhongshan Hospital Affiliated to Fudan University from April 2015 to November 2016 were enrolled. The patients with age > 18 years and the length of hospital stay > 24 hours were included. Records including blood Lac, serum creatinine (SCr), white blood cell count (WBC), platelet count (PLT), sequential organ failure assessment (SOFA) on the first day of admission; minimum oxygen index (PaO2/FiO2) in 3 days after admission; mechanical ventilation, whether there was a history of diabetes, usage of biguanides, etiology control treatment, usage of continuous renal replacement therapy (CRRT) were collected. According to the level of blood Lac patients were divided into high Lac group (Lac > 2 mmol/L) and low Lac group (Lac ≤ 2 mmol/L);based on their diabetic history, sepsis patients were divided into the diabetes group and non-diabetes group. The survival curve of each group was analyzed by Kaplan-Meier regression analysis, and the factors influencing the prognosis were analyzed by multivariate Cox regression analysis.Results There were 76 males and 30 females sepsis patients, with an average age of (68.1±14.7) years old. In the 51 patients of low Lac group, there were 7 patients who suffered from diabetes. While in the 55 patients of high Lac group, there were 12 patients who suffered from diabetes. Compared with low Lac group, high Lac group had a higher age, higher SOFA score, and a lower proportion of patients who had the treatment of etiology control (allP < 0.05). There was no significant difference of blood Lac in sepsis patients with diabetes and those without diabetes (mmol/L: 3.03±2.73 vs. 2.81±2.40,P > 0.05). Kaplan-Meier survival curve analysis showed that the 90-day survival rate in the high Lac group was significantly lower than that in the low Lac group (56.36% vs. 90.20%,χ2 = 0.697,P = 0.008). The high Lac group without diabetes had lower survival rate, and the 90-day survival rate was significantly lower than that of the low Lac group without diabetes (58.14% vs. 90.90%,χ2 = 7.152,P = 0.007); there was no significant difference in 90-day survival rate between the high Lac group and the low Lac group with diabetes (50.00% vs. 85.71%,χ2 = 0.012,P = 0.914). Multivariate Cox regression analysis showed that blood Lac was an independent risk factor for the prognosis of sepsis patients [odds ratio (OR) = 3.863, 95% confidence interval (95%CI) = 1.237-12.060,P = 0.020]. After stratification according to their diabetic history, the blood Lac was an independent risk factor for the prognosis of sepsis patients without diabetes (OR = 4.816, 95%CI = 1.407-15.824, P = 0.010), but the blood Lac had no effect on the prognosis of sepsis patients with diabetes (OR = 0.000, 95%CI =0.000-1.103,P = 0.270).Conclusions The predictive value of blood Lac on sepsis patients with or without diabetes was different. The blood Lac was related with the prognosis of sepsis patients without diabetes, while further study should be conducted for the prognostic value of blood Lac in sepsis patients with diabetes, and it's possible to increase the cut-off-point of Lac level in these patients.

Objective:
To investigate the status of iodine nutrition and prevalence of goiter among children at ages of 8 to 10 years in Zhejiang Province in 2021, so as to provide insights into the management of iodine deficiency in children.
Methods :
A total of 90 counties (districts) were sampled as field survey sites from 11 cities of Zhejiang Province using a multi-stage stratified random sampling method in 2021, and non-residential children at ages of 8 to 10 years in these sites were sampled as study subjects. Subjects' household edible salt samples and random urine samples were collected. The iodine content in salt and urinary iodine level were determined using the direct titration method and arsenic-cerium catalytic spectrophotometry for evaluation of iodine nutrition among children. In addition, the lateral lobe of the thyroid gland was measured using ultrasound, and the prevalence of goiter was estimated.
Results:
A total of 19 363 children were recruited, including 9 710 male children and 9 653 female children, with a male to female ratio of 1.01︰1, and there were 10 704 urban children (55.28%) and 8 659 rural children (44.72%), 9 149 children living in coastal areas (47.25%) and 10 214 children in inland regions (52.75%). The mean iodine content was (19.79±9.25) mg/kg in salt, and the coverage of qualified iodized salt (15 252) was 78.77%. The coverage of qualified iodized salt was significantly lower in urban children than in rural children (76.70% vs. 81.21%; χ2=68.301, P<0.001), and was lower in children living in coastal regions than in inland regions (68.05% vs. 88.27%; χ2=1 270.769, P<0.001). The median urinary iodine concentration was 195.1 μg/L, and the household iodine content in salt correlated positively with urinary iodine concentration in children (rs=0.383, P<0.001). There were 2 885 children with iodine deficiency (14.90%), 7 137 children with adequate iodine (36.86%), 5 414 children with excessive iodine intake (27.96%), and 3 927 children with iodine overdose (20.28%), and the distribution of iodine nutrition in children varied significantly in regions (χ2=283.277, P<0.001) and gender (χ2=126.349, P<0.001). The prevalence of goiter was 2.45% among 7 195 children receiving ultrasound examinations, and a higher prevalence rate of goiter was detected in urban children than in rural children (2.76% vs. 2.00%; χ2=3.962, P=0.047).
Conclusions
The overall urinary iodine nutrition was adequate among children at ages of 8 to 10 years in Zhejiang Province in 2021, and the prevalence of goiter in children fell within the threshold defined in the criteria of elimination of iodine deficiency. However, the supervision of the iodized salt quality remains to be improved and iodine deficiency control remains to be reinforced.

Objective:To evaluate the current situation of prevention and control of iodine deficiency disorders (IDD), and to describe the iodine nutrition level of pregnant women in key population in Zhejiang Province.Methods:In 2021, a cross-sectional survey on iodine nutrition status of the population was conducted in all 90 counties (cities, districts) in Zhejiang Province. Each county (city, district) was divided into five districts: east, west, south, north, and central. One township (street) was selected from each district, and 20 pregnant women were selected from each township (street) to collect edible salt samples and one random urine sample for salt and urinary iodine testing. The above indicators were stratified and analyzed according to urban, rural, coastal, inland, early pregnancy, mid pregnancy, and late pregnancy.Results:A total of 9 679 pregnant women's salt samples were tested, with a salt iodine content of (20.2 ± 9.2) mg/kg, an iodized salt coverage rate of 84.2% (8 153/9 679), and a qualified iodized salt consumption rate of 80.4% (7 785/9 679). Among them, the qualified iodized salt consumption rate of pregnant women in coastal areas was 69.4% (3 175/4 575), significantly lower than that in inland areas [90.3% (4 610/5 104)]; and the proportion of non iodized salt consumption in coastal areas [25.8% (1 181/4 575)] was significantly higher than inland areas [6.8% (345/5 104)]. A total of 9 679 pregnant women's urine samples were tested, with a median urinary iodine of 133.0 μg/L ( < 150 μg/L). In urban areas, the median urinary iodine (129.8 μg/L) was lower than that in rural areas (135.0 μg/L). Likewise, the median urinary iodine was 126.0 μg/L, lower than inland areas (140.3 μg/L). And as pregnancy progressed, the iodine nutrition level of pregnant women gradually decreased (the median urinary iodine: 137.0 μg/L in early pregnancy, 134.1 μg/L in mid pregnancy, and 129.4 μg/L in late pregnancy).Conclusion:In 2021, pregnant women in Zhejiang Province are in a state of iodine deficiency, and there is a greater risk in urban areas compared to rural areas and coastal areas compared to inland areas.

Objective:To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021.Methods:A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children.Results:The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M ( Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 ( χ 2trend=111.427, P<0.001). The median of urinary iodine concentration M ( Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [ M ( Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [ M ( Q1, Q3): 173.00 (113.00, 250.30) μg/L] ( P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95% CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95% CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95% CI: 2.64%-3.10%), 588/20 530] ( P=0.001). Conclusion:From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.
