RESUMO
We aimed to assess dietary iodine intake and sources in Zhejiang Province a decade after a reduction in iodine concentration in iodized salt. Three-day 24 h dietary recall and household weighing were used, complemented by "Chinese Food Composition" data. Household water and salt samples were collected from 5890 residents and analyzed. Differences in iodized salt consumption rates were observed across the following regions: inland (84.20%), subcoastal (67.80%), and coastal (37.00%) areas. The median (P25, P75) iodine concentration in water and diet were 2.2 (0.9, 4.0) µg/L and 142.05 (58.94, 237.11) µg/d, respectively, with significant regional differences in dietary concentration (inland [185.61 µg/d], subcoastal [153.42 µg/d], and coastal [75.66 µg/d]). Males (149.99 µg/d) and iodized salt consumers (191.98 µg/d) had a significantly higher dietary iodine intake than their counterparts. Regions were ranked as follows based on the proportions of individuals meeting the recommended dietary iodine intake: inland (69.40%), subcoastal (56.50%), and coastal (34.10%) areas. Dietary sources included salt (48.54%), other foods (32.06%), drinking water (8.84%), laver (4.82%), kelp (3.02%), and other seafood (2.32%). The qualified iodized salt consumption rate was significantly lower than the national standard. Zhejiang Province should continue implementing measures to control iodine deficiency through salt iodization, education efforts, and increasing the qualified iodized salt consumption rate.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is characterized by high recurrence rates and poor prognosis, and effective first-line treatment is lacking. Recently, histone deacetylase inhibitors (HDACi), such as chidamide, have been found to induce durable remissions in AITL patients. Methods: Patients with untreated AITL from March 2015 to March 2023 were retrospectively collected and divided into chemotherapy (ChT) group and chidamide combined with chemotherapy (C-ChT) group based on the first-line treatment received. The comparison of efficacy and safety between the two groups was conducted. Results: 86 patients with newly diagnosed AITL were enrolled, in which 35 patients were in the ChT group and 51 in the C-ChT group. The objective response rate (ORR) of C-ChT group was significantly higher than that of ChT group (84.3% vs. 60%, P= 0.011), and had superior progression-free survival (PFS) (27 months vs. 12 months, P= 0.025). However, no significant difference in overall survival (OS) was observed between the two groups (P= 0.225). In addition, the responding patients who received autologous stem cell transplantation (ASCT) had superior PFS compared to those who did not (P= 0.015). Conclusions: Compared with ChT regimen, C-ChT regimen was well tolerated and had superior ORR and PFS in patients with untreated AITL. ASCT may contribute to longer PFS in remission patients.
RESUMO
The biosynthesis of thyroid hormones is essential for brain and neurological development. It requires iodine as a key component but is also influenced by other nutrients. Evidence for the combined nutrient status in relation to thyroid hormones during pregnancy is limited. We aimed to investigate the joint associations of iodine, selenium, zinc, calcium, magnesium and iron with maternal thyroid functions in 489 pregnant women from Hangzhou, China. Serum levels of six essential minerals and thyroid function parameters were measured during the first antenatal visit. Linear regression, quantile g-computation and Bayesian kernel machine regression were used to explore the individual and joint relationships between the six minerals and thyroid hormones. Linear regression analyses revealed that calcium was positively associated with free triiodothyronine (FT3). Zinc was positively associated with free thyroxine (FT4). Iodine was negatively associated with thyroid-stimulating hormone (TSH) and positively associated with FT3 and FT4. The quantile g-computation and BKMR models indicated that the joint nutrient concentration was negatively associated with TSH and positively associated with FT3 and FT4. Among the six minerals, iodine contributed most to thyroid function. The findings suggested that maintaining the appropriate concentration of minerals, either as individuals or a mixture, is important for thyroid health during pregnancy.

SUMMARY: Coreopsis tinctoria Nutt. (C. tinctoria Nutt.) can protect diabetic kidneys, but the mechanisms are unclear. This work is to investigate the potential mechanisms of C. tinctoria Nutt. in the treatment of diabetic nephropathy based on network pharmacology analysis of its active ingredients. Twelve small molecular compounds of C. tinctoria Nutt. and targets related to diabetic nephropathy were docked by Discovery Studio 3.0. DAVID database was used for GO enrichment and KEGG pathway analysis. Cytoscape 3.6.1 was used to construct active ingredient-target network. Cell viability was detected with MTT. Glucose consumption was analyzed with glucose oxidase method. Protein expression was measured with Western blot and immunofluorescence. Electron microscopy observed autophagosomes. The core active ingredients of C. tinctoria Nutt. included heriguard, flavanomarein, maritimein, and marein. Twenty-one core targets of the 43 potential targets were PYGM, TLR2, RAF1, PRKAA2, GPR119, INS, CSF2, TNF, IAPP, AKR1B1, GSK3B, SYK, NFKB2, ESR2, CDK2, FGFR1, HTRA1, AMY2A, CAMK4, GCK, and ABL2. These 21 core targets were significantly enriched in 50 signaling pathways. Thirty- four signaling pathways were closely related to diabetic nephropathy, of which the top pathways were PI3K/AKT, insulin, and mTOR, and insulin resistance. The enriched GO terms included biological processes of protein phosphorylation, and the positive regulation of PI3K signaling and cytokine secretion; cellular components of cytosol, extracellular region, and extracellular space; and molecular function of protein kinase activity, ATP binding, and non-membrane spanning protein tyrosine kinase activity. In vitro experiments found that marein increased the expression of phosphorylated AKT/AKT in human renal glomerular endothelial cells of an insulin resistance model induced by high glucose, as well as increased and decreased, respectively, the levels of the microtubule-associated proteins, LC3 and P62. C. tinctoria Nutt. has many active ingredients, with main ingredients of heriguard, flavanomarein, maritimein, and marein, and may exert anti-diabetic nephropathy effect through various signaling pathways and targets.
RESUMEN: Coreopsis tinctoria Nutt. (C. tinctoria Nutt.) puede proteger riñones diabéticos, sin embargo los mecanismos son desconocidos. Este trabajo se realizó para investigar los potenciales mecanismos de C. tinctoria Nutt. en el tratamiento de la nefropatía diabética basado en el análisis de farmacología en red de sus principios activos. Doce compuestos moleculares pequeños de C. tinctoria Nutt. y los objetivos relacionados con la nefropatía diabética fueron acoplados por Discovery Studio 3.0. La base de datos DAVID se utilizó para el enriquecimiento GO y el análisis de la vía KEGG. Se usó Cytoscape 3.6.1 para construir una red de ingrediente-objetivo activa. La viabili- dad celular se detectó mediante MTT. El consumo de glucosa se analizó con el método de glucosa oxidasa. La expresión proteica fue determinada mediante Western blot e inmunofluorescencia. En la microscopía electrónica se observó autofagosomas. Los principales ingredientes activos de C. tinctoria Nutt. incluyeron heriguard, flavanomarein, maritimin y marein. Veintiún de los 43 objetivos potenciales fueron PYGM, TLR2, RAF1, PRKAA2, GPR119, INS, CSF2, TNF, IAPP, AKR1B1, GSK3B, SYK, NFKB2, ESR2, CDK2, FGFR1, HTRA1, AMY2A, CAMK4, GCK y ABL2. Estos 21 objetivos principales se enriquecieron significativamente en 50 vías de señalización. Treinta y cuatro vías de señalización estuvieron estrechamente relacionadas con la nefropatía diabética, de las cuales las principales vías fueron PI3K/ AKT, insulina y mTOR, y resistencia a la insulina. Los términos GO enriquecidos incluyeron procesos biológicos de fosforilación proteica, la regulación positiva de la señalización de PI3K y la secreción de citoquinas; componentes celulares del citosol, región extracelular y espacio extracelular; y la función molecular de la actividad de la proteína quinasa, la unión de ATP y la actividad de la proteína tirosina quinasa que no se extiende por la membrana. Los experimentos in vitro encontraron que la mareína aumentaba la expresión de AKT/AKT fosforilada en células endoteliales glomerulares renales humanas en un modelo de resistencia a la insulina inducida por niveles elevados de glucosa, así como aumentaron y disminuyeron respectivamente, los niveles de las proteínas asociadas a los microtúbulos, LC3 y P62. C. tinctoria Nutt. tiene muchos principios activos, con ingredientes principales de heriguard, flavanomarein, maritimain y marein, y puede ejercer un efecto de nefropatía antidiabética a través de distintass vías de señalización y objetivos.
