Objective:To investigate the iodine nutrition level and thyroid function status of pregnant women in Hubei Province.Methods:According to the requirements of "the National Iodine Deficiency Disorders Monitoring Program (2016 Edition)", in 2020, using a cross-sectional survey method, two mountainous counties and two plain areas in Hubei Province were 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) as survey subjects. Urine iodine content and thyroid function indicators [serum free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb)] were tested. Abnormal thyroid function rate and antibody positive rate were analyzed, and correlation analysis of thyroid function indicators was conducted (Spearman method). Results:A total of 321 pregnant women were included, including 43, 114, and 164 in early, middle, and late pregnancy, respectively; The median urinary iodine was 164.80 μg/L. The median serum FT 3, FT 4, TSH, TPOAb, TgAb levels were 4.10, 12.83 pmol/L, 1.85 mU/L, 15.84 and 13.35 U/ml, respectively. There were statistically significant differences in FT 3, FT 4, and TSH levels among different trimesters ( P < 0.05). According to Spearman's correlation analysis, FT 3 in early stage of pregnancy was negatively correlated with TSH and TPOAb levels ( r = - 0.46, - 0.33, P < 0.05), while TSH was positively correlated with TPOAb level ( r = 0.33, P = 0.032); there was a positive correlation between FT 4 and TgAb levels in middle stage of pregnancy ( r = 0.21, P = 0.032); there was a negative correlation between FT 3 and TPOAb levels in late stage of pregnancy ( r = - 0.19, P = 0.017); FT 3 and FT 4, TPOAb and TgAb levels were positively correlated throughout pregnancy ( P < 0.05). There was no correlation between urinary iodine content and thyroid function indicators ( P > 0.05). The total abnormal rate of thyroid function was 7.79% (25/321), with 16.28% (7/43), 5.26% (6/114), and 7.32% (12/164) in early, middle, and late pregnancy, respectively. There was no statistically significant difference in the abnormal rate of thyroid function among different pregnancy periods (χ 2 = 4.83, P = 0.097). The detection rates of hypothyroxinemia, hypothyroidism, subclinical hypothyroidism, hyperthyroidism, and subclinical hyperthyroidism were 4.36% (14/321), 0.31% (1/321), 2.49% (8/321), 0.31% (1/321), and 0.31% (1/321), respectively. The positive detection rate of autospecific antibodies was 10.28% (33/321), with a TPOAb positive detection rate of 9.97% (32/321) and a TgAb positive detection rate of 5.30% (17/321). Conclusions:The iodine nutrition level of pregnant women in Hubei Province is at a suitable level, and the rates of abnormal thyroid function and thyroid autospecific antibody positive are relatively low. It is necessary to continuously monitor the iodine nutrition and thyroid function indexes of pregnant women, strengthen health education on the hazards of iodine deficiency during pregnancy, and minimize the harm to maternal and infant health caused by iodine deficiency.

OBJECTIVE To predict the core ingredients, targets and signaling pathways of Sanhuang ointment in the treatment of haemorrhoids based on network pharmacology, and preliminarily discuss the mechanism of action preliminarily by means of molecular docking and experimental verification. METHODS Active ingredients, targets and haemorrhoid related targets of Sanhuang ointment were obtained through literature research and database screening. Association networks were constructed and core targets were screened by Cytoscape, and gene function analysis and pathway enrichment analysis were conducted. Autodock Vina was used for molecular docking verification, and the regulatory effects of Sanhuang ointment on core targets were verified by ELISA and immunohistochemistry. RESULTS The 77 active ingredients and 61 potential targets of Sanhuang ointment for treating haemorrhoids were collected. KEGG showed that Sanhuang ointment could regulate calcium signaling pathways, neuroactive ligand receptor interactions, cGMP-PKG pathway, etc. Affect 6 core targets of CGRP, NK-1R, TRPV1, VEGF, IL-6 and TNF-α. Molecular docking showed that Sanhuang ointment had a good affinity with target protein, and animal experiments verified that Sanhuang ointment could inhibit the expression of IL-6, CGRP, substance P, and promote the expression of VEGF. CONCLUSION Sanhuang ointment may act on CGRP, NK-1R and other targets, regulate Calcium signaling pathway and PI3K-Akt pathways, and exert analgesic and anti-inflammatory effects, promoting blood circulation and removing blood stasis to treat haemorrhoids.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVE: To assess the value of non-invasive prenatal testing (NIPT) for women with advanced gestational age but normal measurement for nuchal translucency (NT). METHODS: A total of 9371 singleton pregnancies with negative NT screening at early pregnancy were reviewed. Among these, 8627 cases were selected to be screened again by NIPT, and their indications and results were analyzed. The results were compared with those of with other high risk factors and young gestational age. RESULTS: The incidence of fetal aneuploidies increased in women with advanced gestational age and ultrasound soft markers, in particular among those who were negative for NT screening but over the age of 37. The detection rate of pathological or likely pathological copy number variations was 1.88% among women who directly underwent invasive prenatal diagnosis because of the advanced age, but there was no correlation with the increase of age. 0.68% of the women where with negative NT screening and NIPT still need to undergo invasive prenatal diagnosis. CONCLUSION After NT screening in early pregnancy, NIPT can replace invasive prenatal diagnosis for those below the age of 37, though there is still a possibility of missed detection of pathogenic copy number variation. It is necessary to strengthen ultrasonic monitoring in later period.
