Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

OBJECTIVE To explore the effects of CD20 coding gene （MS4A1） polymorphism on the blood concentration and efficacy of rituximab in patients with non-Hodgkin’s lymphoma. METHODS A prospective observational study was conducted on 160 newly diagnosed non-Hodgkin’s lymphoma patients who received the R-CHOP regimen at the Sun Yat Sen University Cancer Center from January 2016 to December 2020， with a minimum follow-up period of approximately 5 years. The blood concentration of rituximab was detected by enzyme-linked immunosorbent assay. MS4A1 tagSNPs were selected by Haploview4.2 software， including rs1051461， rs17155034， rs4939364， and rs10501385. The genotype of MS4A1 was detected by Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Univariate linear regression analysis was employed to examine the correlation between various factors（demographic， clinical， and genotypic variables） in patients and the steady-state trough concentration of rituximab during the first course of treatment， followed by multivariate linear regression analysis. Kaplan-Meier curves were drawn to evaluate progression-free survival （PFS） and overall survival （OS）. Using MS4A1 genotype and tumor stage as independent variables， Cox regression model was employed to evaluate the factors influencing patient prognosis. RESULTS The blood concentration of rituximab in MS4A1 rs10501385 CC carriers was 15.20 μg/mL，which was significantly lower than 21.95 μg/mL in AA+AC carriers （P＜0.05）. The multivariate linear regression model incorporating tumor stage and MS4A1 rs10501385 polymorphism explained 7.3% of the interindividual variability in rituximab concentrations. Compared with MS4A1 rs1051461 CC carriers， CT+TT carriers had significantly prolonged PFS and OS （P＜0.05）. The Cox proportional hazards regression model showed that the MS4A1 rs1051461 CC genotype （HR＝4.406， 95%CI：1.743-11.137， P＜0.05） and tumor Ⅲ&Ⅳ （HR＝3.233， 95%CI： 1.413-7.399， P＜0.05） were independent risk factors for PFS. CONCLUSIONS The tumor staging and MS4A1 rs10501385 polymorphism are key influencing factors for blood concentration of rituximab， and MS4A1 rs1051461 polymorphism significantly affects PFS in non-Hodgkin’s lymphoma patients.

The innate immune sensor NLRP3 inflammasome overactivation is involved in the pathogenesis of ulcerative colitis. PGAM5 is a mitochondrial phosphatase involved in NLRP3 inflammasome activation in macrophages. However, the role of PGAM5 in ulcerative colitis and the mechanisms underlying PGAM5 regulating NLRP3 activity remain unknown. Here, we show that PGAM5 deficiency ameliorates dextran sodium sulfate (DSS)-induced colitis in mice via suppressing NLRP3 inflammasome activation. By combining APEX2-based proximity labeling focused on PGAM5 with quantitative proteomics, we identify NEK7 as the new binding partner of PGAM5 to promote NLRP3 inflammasome assembly and activation in a PGAM5 phosphatase activity-independent manner upon inflammasome induction. Interfering with PGAM5-NEK7 interaction by punicalagin inhibits the activation of the NLRP3 inflammasome in macrophages and ameliorates DSS-induced colitis in mice. Altogether, our data demonstrate the PGAM5-NEK7 interaction in macrophages for NLRP3 inflammasome activation and further provide a promising therapeutic strategy for ulcerative colitis by blocking the PGAM5-NEK7 interaction.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Inflammation plays a pivotal role in the etiology and progression of various diseases. In traditional Chinese medicine, the whole plants of Thesium chinense Turcz. and its preparations (e.g. Bairui Granules) have been employed to manage inflammatory conditions. While flavonoids were previously considered the primary anti-inflammatory components, other potentially active constituents have been largely overlooked and not thoroughly investigated. This study presents a novel finding that the total alkaloids of T. chinense (BC-Alk) are potent active substances underlying the traditional and clinical applications of T. chinense and Bairui Granules as anti-inflammatory agents. UPLC-MS/MS analysis identified the composition of BC-Alk as quinolizidine alkaloids. The anti-inflammatory efficacy of BC-Alk was evaluated using a lipopolysaccharide (LPS)-induced lung inflammation model in mice. Results demonstrated that BC-Alk significantly mitigated LPS-induced lung inflammation, attenuated the overproduction of IL-1β and the overproduction of inflammatory factors (TNF-α), and ameliorated lung tissue hyperplasia in mice in vivo. Mechanistic studies in vitro revealed that BC-Alk upregulated the expression of Nrf2 and its downstream proteins NQO1 and glutamate-cystine ligase and modifier subunit (GCLM), inhibited NF-κB phosphorylation, and suppressed NLRP3 activation. Collectively, these findings indicate that BC-Alk exerts potent inhibitory effects against lung inflammation by modulating Nrf2, NF-κB, and NLRP3 pathways. This study provides new insights into the anti-inflammatory constituents of T. chinense and Bairui Granules.

Objective To mine and analyze the adverse event data of polatuzumab vedotin(Pola)and fam-trastuzumab deruxtecan-nxki(T-Dxd),so as to provide reference for clinical medication safety.Methods The adverse events reported from January 1,2004 to June 7,2023 were extracted based on openFDA database.The suspicious risk signals were screened by the Open Vigil 2.1 data platform and ranked by signal strength and frequency of occurrence;then ADEs were classified by reference to the MedDRA 26.0.Results A total of 7 164 and 22 870 ADE reports related to Pola and T-Dxd were obtained,and 104 and 95 suspicious ADE signals were detected,respectively.According to the signal intensity,cytomegalovirus enterocolitis(ROR=416.94)for Pola and interstitial lung disease[reporting odds ratio(ROR)=82.55]for T-Dxd ranked first,both of which were recorded in the drug instructions.According to the frequency of occurrence,the two drugs were most frequently associated with death(n=111)and nausea(n=285),respectively.The risk of Pola was associated with 12 systems/organs,of which 26 risk signals were not documented in the drug instruction,and the risk of T-Dxd was associated with 13 systems/organs,of which 18 risk signals were not documented in the drug instruction.Conclusion By tapping the ADE after real-world administration of Pola and T-Dxd,physicians are prompted to pay attention to the risk of adverse reactions in clinical use and actively take preventive and therapeutic measures to ensure the safety of patients'medication.

Objective To explore the mechanism of tumor-associated fibroblasts(CAFs)for regulating proliferation and migration of prostate cancer(PCa)cells.Methods We conducted a bioinformatics analysis to identify miRNAs with high expression in PCa.The proliferation,migration and hsa-miR-18b-5p expression levels were observed in PCa cells co-cultured with CAFs.We further examined hsa-miR-18b-5p expression level in 20 pairs of PCa and adjacent tissue samples and in different PCa cell lines and normal epithelial cells using RT-qPCR.In PCa cell lines C4-2 and LNCAPNC,the effects of transfection with a hsa-miR-18b-5p inhibitor on cell proliferation,migration,invasion,drug resistance,apoptosis and cell cycle were evaluated,and the effects of has-miR-18b-5p knockdown on C4-2 cell xenograft growth and mouse survival were observed in nude mice.Dual luciferase reporter gene assay was used to validate the targeting relationship between hsa-miR-18b-5p and its target genes,whose expressions were detected in PCa cells using RT-qPCR and Western blotting.Results The expression of hsa-miR-18b-5p was significantly increased in the co-culture of CAFs and PCa cell lines,which exhibited significantly enhanced proliferation and migration abilities.Transfection with has-miR-18b-5p inhibitor strongly attenuated the effect of CAFs for promoting proliferation and migration of PCa cells,and in C4-2 and LNCAP cells cultured alone,inhibition of hsa-miR-18b-5p obviously suppressed cell proliferation,migration,invasion,and drug resistance.In the tumor-bearing mice,hsa-miR-18b-5p knockdown in the transplanted cells significantly inhibited xenograft growth and increased the survival time of the mice.Target gene prediction suggested that FBXL3 was a potential target of hsa-miR-18b-5p,and dual luciferase reporter gene confirmed a binding site between them.In C4-2 and LNCAP cells,hsa-miR-18b-5p knockdown resulted in significantly increased expression levels of FBXL3.Conclusion CAFs promotes proliferation and migration of PCa cells by up-regulating hsa-miR-18b-5p to suppress FBXL3 expression.

Objective To investigate renal expression level of STING in mice with renal ischemia-reperfusion injury(IRI)and its regulatory role in IRI.Methods C57BL/6 mice were divided into sham operation group,IRI(induced by clamping the renal artery)model group,IRI+DMSO treatment group,and IRI+SN-011 treatment group.Serum creatinine and blood urea nitrogen of the mice were analyzed,and pathological changes in the renal tissue were assessed with PAS staining.RT-qPCR,ELISA,Western blotting,and immunohistochemistry were used to detect the expression levels of STING,KIM-1,Bcl-2,Bax,caspase-3,TLR4,P65,NLRP3,caspase-1,CD68,MPO,IL-1β,IL-6,and TNF-α in the renal tissues.In the cell experiment,HK-2 cells exposed to hypoxia-reoxygenation(H/R)were treated with DMSO or SN-011,and cellular STING expression levels and cell apoptosis were analyzed using RT-qPCR,Western blotting or flow cytometry.Results In C57BL/6 mice,renal IRI induced obvious renal tissue damage,elevation of serum creatinine and blood urea nitrogen levels and renal expression levels of KIM-1,STING,TLR4,P65,NLRP3,caspase-1,caspase-3,Bax,CD68,MPO,IL-1β,IL-6,and TNF-α,and reduction of Bcl-2 expression level.Treatment of the mouse models with SN-011 for inhibiting STING expression significantly alleviated these changes.In HK-2 cells,H/R exposure caused significant elevation of cellular STING expression and obviously increased cell apoptosis rate,which was significantly lowered by treatment with SN-011.Conclusion Renal STING expression is elevated in mice with renal IRI to exacerbate renal injury by regulating the TLR4/NF-κB/NLRP3 pathway and promoting inflammation and apoptosis in the renal tissues.
