Objective:To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] levels and 24-h urinary calcium excretion (24-h UCaE) and hypercalciuria in Chinese adults.Methods:This cross-sectional study was conducted from March 2022 to March 2023 in nine cities in China and included 1 239 residents. Demographic characteristics were collected through questionnaires and physical examinations, fasting blood samples were assessed for bone metabolism indicators, and 24-h urine samples were used to determine the 24-h UCaE. Multiple linear regression analysis was used to explore the relationship between serum 25(OH)D and 24-h UCaE and bone metabolism indexes. The relationship between serum 25(OH)D and hypercalciuria was analyzed using a multiple logistic regression model combined with restricted cubic spline modeling.Results:The mean participant age was (47.9±18.1) years, of which 453 (36.6%) were male. The percentages of vitamin D sufficiency, insufficiency, and deficiency were 7.6% (94/1 239), 29.0% (359/1 239), and 63.4% (786/1 239), respectively. The multiple linear regression model showed that after adjusting for the covariates the 24-h UCaE gradually increased with higher levels of 25(OH)D ( P overall <0.001, P nonlinear <0.001). The logistic regression analysis revealed that compared with the vitamin D deficient group, the OR for the prevalence of hypercalciuria in the vitamin D sufficient and vitamin D insufficient groups were 3.290 (95% CI 1.745 to 6.202) and 3.742 (95% CI 2.458 to 5.697), respectively. The results of the restricted cubic spline modeling showed a positive nonlinear relationship between 25(OH)D and the prevalence of hypercalciuria ( P overall <0.001, P nonlinear <0.001). The prevalence of hypercalciuria increased when 25(OH)D was >17.00 μg/L and peaked at 26.71 μg/L, after which there was a decreasing trend in the prevalence of hypercalciuria with increasing 25(OH)D. Conclusion:Associations between serum 25(OH)D levels and urinary calcium excretion and the prevalence of hypercalciuria were observed in the Chinese adult population.

ObjectiveTo explore the regulatory effects and mechanisms of Astragali Radix polysaccharide （APS） on inhibitor of differentiation1 （ID1） and protein kinase B （Akt） in gastric cancer. MethodsImmunohistochemical staining was used to detect the expression of ID1 and Akt in 61 gastric cancer tissue samples and 20 adjacent normal gastric tissue samples. Immunofluorescence was used to detect the localization of ID1 and Akt. The effects of APS at the concentrations of 0.625， 1.25， 2.5， 5， 10， 20 mg·L^-1 on the proliferation of gastric cancer MGC-803 cells were examined by the cell counting kit-8（CCK-8） method and the colony formation assay. The target information of APS was retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Platform and Swiss Target Prediction. Keywords such as gastric cancer， gastric tumor， and stomach cancer were searched against GeneCards， UniProt， DisGeNET， and Online Mendelian Inheritance in Man （OMIM） for the screening of gastric cancer-related targets. The online tool jvenn was used to create the Venn diagram to identify the common targets， and STRING and Cytoscape were used to construct the protein-protein interaction network. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were conducted via R 4.2.2 to predict the potential roles of APS in the development of gastric cancer. The cell scratch assay was employed to assess the effect of APS on the migration of MGC-803 cells. The protein and mRNA levels of ID1 and Akt in the cells treated with APS were determined by Western blot and Real-time PCR， respectively. ResultsCompared with the adjacent normal gastric tissue， the gastric adenocarcinoma tissue showed increased positive expression of ID1 （χ² =81.00， P<0.01）. Immunofluorescence detection showed that ID1 and Akt were mainly located in the cytoplasm of gastric adenocarcinoma cells. Bioinformatics analysis identified 14 common genes shared between APS and gastric cancer. The average degree of protein-protein interaction network nodes was 14.29. GO and KEGG pathway enrichment results showed that ID1 and Akt were significantly enriched in the Rap1 and phosphatidylinositol-3-kinase （PI3K） /Akt signaling pathways. Cell experiments demonstrated that 5-fluorouracil （0.1 mg·L^-1） and APS （10， 20 mg·L^-1） groups showed decreased cell proliferation， migration， and colony formation. Compared with the control group， 10， 20 mg·L^-1 APS inhibited the proliferation of MGC-803 cells （P<0.01）， with 10 mg·L^-1 APS demonstrating stronger inhibitory effect. In addition， APS at 10， 20 mg·L^-1 inhibited the migration （P<0.01） and colony formation （P<0.05， P<0.01） of MGC-803 cells. Compared with the control group， APS at 10， 20 mg·L^-1 down-regulated the protein levels of ID1 （P<0.01） and Akt （P<0.05） and the mRNA levels of ID1 （P<0.05， P<0.01） and Akt （P<0.05， P<0.01） in MGC-803 cells. ConclusionID1 and Akt are highly expressed in the gastric adenocarcinoma tissue， which may be related to the development of gastric cancer. APS can down-regulate the protein and mRNA levels of ID1 and Akt to exert anti-tumor effects， which is expected to provide new therapeutic targets for gastric cancer treatment.

Objective:To analyze the clinical features of postnatal cytomegalovirus (pCMV) infection in very preterm infants or very low birth weight infants.Methods:This was a case-control study. A total of 50 very preterm or very low birth weight infants who were hospitalized and diagnosed with pCMV infection in the Neonatal Intensive Care Unit of Children′s Hospital, Zhejiang University School of Medicine from January 2019 to June 2024, were enrolled as the pCMV group. Meanwhile, through propensity score matching, each infant in the pCMV group was paired with a very preterm or very low birth weight infant without cytomegalovirus infection during the same period, constituting the control group, also consisting of 50 cases. Subsequently, the pCMV group was divided into a treated subgroup and an untreated subgroup according to antiviral treatment. Clinical data of all enrolled infants, including clinical features, laboratory test results, and clinical outcomes were collected. Differences in relevant parameters were analyzed using with χ2 test or continuity-corrected χ2 test or Fisher′s exact test, independent-samples t test, Mann-Whitney U test as appropriate. Logistic regression was employed to analyze the risk factors, and Spearman correlation analysis was applied for non-normal distribution data or ordinal data. Results:There were no significant differences between the pCMV group and the control group in terms of gestational age, birth weight, proportion of male infants, Apgar score at the 1 st minute and 5 th minute and days of breastfeeding during the first 3 weeks of life (all P>0.05). Compared with the control group, the duration of hospital stay and invasive mechanical ventilation were both longer in the pCMV group (both P<0.05). The risks of bronchopulmonary dysplasia, retinopathy of prematurity, and hearing impairment were all higher in the pCMV group when compared with the control group(all P<0.05). The body weight and body length of the infants in the pCMV group were both lower than those of in the control group at the corrected gestational age of 36 weeks (both P<0.05). pCMV infections were associated with the increased incidence of both necrotizing enterocolitis ( OR=11.50, 95% CI 1.94-68.30, P=0.007) and severe intraventricular hemorrhage ( OR=6.82, 95% CI 1.19-38.97, P=0.031) in very preterm infants or very low birth weight infants. In the treated group, the platelet count was significantly improved after 6-8 weeks of antiviral treatment compared with that before treatment ((245±19)×10 9/L vs. (119±14)×10 9/L, t=5.37, P<0.001). Conclusions:Very preterm infants or very low birth weight infants with postnatal cytomegalovirus infection have longer hospital stay and duration of invasive mechanical ventilation, and are highly susceptible to bronchopulmonary dysplasia, retinopathy of prematurity, hearing impairment, and growth restriction. Antiviral treatment can effectively ameliorate thrombocytopenia in these infants.
