Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

Objective: To analyze the current situation of adolescent depressive symptoms in singleparent families in Jianyang City, and to construct and verify the early warning model, so as to provide a scientific basis for the government to formulate a plan of promoting the development of adolescent mental health. Methods: A stratified cluster random sampling method was used to select 12 125 middle and high school students from 25 middle schools in Jianyang City from March 2022 to October 2023 for an anonymous selffilling questionnaire survey, and a total of 1 142 adolescents from valid singleparent families were obtained as the survey objects. They were randomly divided into the training set (914 participants) and the verification set (228 participants) according to the ratio of 8∶2. The Chinese version of Beck depression Inventory (BDI) was used to evaluate depressive symptoms among adolescents from singleparent families in Jianyang City. The factors related of depressive symptoms in adolescents from singleparent families were analyzed, and a prediction model was established to verify the model and evaluate its effectiveness. Results: There were 158 adolescents (17.29%) in the training set and 43 adolescents (18.86%) in the verification set with depressive symptoms. Multivariate Logistic regression analysis showed that learning stress (OR=4.31, 95%CI=1.67-11.13), Connor-Davidson Resilience Scale (CDRISC) score (OR=0.29, 95%CI=0.12-0.71) and Family Adaptability and Cohesion Scale (FACESⅡ) scores (OR=0.19, 95%CI=0.06-0.63) were all related factors the occurrence of depressive symptoms in adolescents from singleparent families (P<0.05). The results showed that the C-index was 0.80 (95%CI=0.75-0.80), and the correction curve for predicting the occurrence of depressive symptoms in singleparent families was close to the ideal curve (χ2=0.26, P>0.05). Receiver operating characteristic (ROC) curve results of the training set showed that the sensitivity and specificity of the nomogram model in predicting depressive symptoms in adolescents from singleparent families were 80.38% and 80.03% respectively, ROC area under the curve (AUC) was 0.84 (95%CI=0.76-0.92). The ROC curve results of the verification set showed that the sensitivity, specificity and AUC of histogram model to predict depressive symptoms in adolescents from singleparent families were 79.07%, 82.16% and 0.83 (95%CI=0.76-0.91). Conclusions Learning stress, mental resilience and family function are all factors that affect the occurrence of depressive symptoms in adolescents from single parent families in Jianyang City. Based on this, the early warning model can predict depressive symptoms in Jianyang City.

Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism, and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-β expression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.

Gliomas are the most common primary intracranial tumors in adults, among which high-grade glioma patients are characterized by short survival and poor prognosis. The diagnosis, treatment, evaluation of effective treatments, and prognosis prediction of high-grade gliomas are of great significance for improving patient survival. Conventional enhanced magnetic resonance imaging has deficiencies in delineating tumor extent, identifying tumor progression and treatment-related changes. Therefore, there is a broad consensus to incorporate amino acid PET, and ¹⁸F-FET PET inparticular, into the diagnostic and therapeutic process of high-grade gliomas. In this article, we review the new research progress of ¹⁸F-FET PET in the diagnosis and treatment of adult high-grade glioma in recent years.
