Sjogren's syndrome (SS) is a common autoimmune disorder that primarily targets exocrine glands, leading to hallmark manifestations of xerostomia and xerophthalmia, with potential progression to multisystem involvement. The rapid advances in omics technologies-including metabolomics, proteomics, and transcriptomics-have yielded substantial insights into SS pathophysiology. This review consolidates current evidence on omics-derived biomarkers in SS. Studies consistently implicate aberrant glucose metabolism, neutrophil-derived enzyme activity, mitochondrial bioenergetic impairment, ferroptosis, and apoptotic pathways as central to SS development. These findings refine our understanding of disease mechanisms and the heterogeneity of therapeutic responses. Hydroxyproline has emerged as a candidate marker for distinguishing SS from IgG4-related disease, whereas distinct cytokine and chemokine signatures may enable earlier diagnosis. Genomic analyses demonstrate a robust association between expression of the rs11797 locus and SS-related lymphomagenesis, and several genes controlling DNA methylation represent promising therapeutic targets. Collectively, these findings lay the groundwork for personalized risk stratification and intervention in SS. The review concludes by summarizing existing progress and outlining priorities for future omics-based investigations.

Objective: To explore the correlation and lag effects of environmental factors on pediatric respiratory disease visits at hospital, so as to provide scientific basis for disease prediction and optimizing clinical diagnosis and treatment. Methods: Data from 503 889 pediatric respiratory disease outpatient and emergency visits a central hospital in Minhang District of Shanghai between 2017 and 2019, along with concurrent meteorological data were collected. A distributed lag non-linear models (DLNM) was constructed to explore the specific relationship between pediatric respiratory disease consultations and various environmental factors and to quantify the cumulative lag effects of environmental factors on respiratory disease consultations. Results: Among the environmental factors, temperature, fine particulate matter (PM 2.5 ), inhalable particulate matter (PM 10 ), nitrogen dioxide (NO 2), and sulfur dioxide (SO 2) were associated with pediatric respiratory disease visits. After adjusting for temperature, PM 2.5 and PM 10 concentrations did not show significant immediate or lag effects. The relative risk (RR) of pediatric respiratory disease visits increased with rising NO 2 concentrations. When NO 2 concentration ≥55 μg/m 3, significant immediate and lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.05, 1.13, 1.17, and 1.21( P <0.05). The RR values showed an inverted “U” shaped relationship with SO 2 concentrations. When SO 2 concentration ≥5 μg/m 3, significant lagged effects (lag 3, 5, and 7 days) were observed. The RR values were 1.03 , 1.03, and 1.04 ( P <0.05). Conclusion High concentrations of NO 2 and SO 2 increase the risk of pediatric respiratory disease visits, with observable lag effects.

Rapid and ultrasensitive detection of pathogen-associated biomarkers is vital for the early diagnosis and therapy of bacterial infections. Herein, we developed a close-packed and ordered Au@AgPt array coupled with a cascade triggering strategy for surface-enhanced Raman scattering (SERS) and colorimetric identification of the Staphylococcus aureus biomarker micrococcal nuclease (MNase) in serum samples. The trimetallic Au@AgPt nanozymes can catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine (TMB) molecules to SERS-enhanced oxidized TMB (oxTMB), accompanied by the color change from colorless to blue. In the presence of S. aureus, the secreted MNase preferentially cut the nucleobase AT-rich regions of DNA sequences on magnetic beads (MBs) to release alkaline phosphatase (ALP), which subsequently mediated the oxTMB reduction for inducing the colorimetric/SERS signal fade away. Using this "on-to-off" triggering strategy, the target S. aureus can be recorded in a wide linear range with a limit of detection of 38 CFU/mL in the colorimetric mode and 6 CFU/mL in the SERS mode. Meanwhile, the MNase-mediated strategy characterized by high specificity and sensitivity successfully discriminated between patients with sepsis (n = 7) and healthy participants (n = 3), as well as monitored the prognostic progression of the disease (n = 2). Overall, benefiting from highly active and dense "hot spot" substrate, MNase-mediated cascade response strategy, and colorimetric/SERS dual-signal output, this methodology will offer a promising avenue for the early diagnosis of S. aureus infection.

Objective:To analyze the clinicopathological features of prostate cancers with BRCA2 pathogenic mutations, and the association between BRCA2 pathogenic mutation and clinicopathological characteristics. Patient survivals were also examined.Methods:Clinicopathological data of 249 prostate cancer patients who underwent genetic testing in West China Hospital of Sichuan University, Chengdu, China from June 2014 to August 2021 were collected. A retrospective analysis of histopathological morphology, clinicopathological characteristics, and patient survivals was conducted.Results:The genetic testing in the 249 prostate cancer patients showed a pathogenic mutation of DNA damage repair gene (DRG) in 73 cases (73/249, 29.3%), including 22 cases (8.8%) with BRCA2 pathogenic mutation and 51 cases with pathogenic mutations of other DRG. Among the 22 patients with BRCA2 pathogenic mutation, 14 patients (5.6%) harbored germline mutations and 8 patients (3.2%) somatic mutations. Their ages ranged from 48 to 91 years, with a median of 67 years. Seventeen patients (77.3%) had distant metastasis, including 16 cases with bone metastasis and 1 case with multiple metastases. Thirteen patients (59.1%) were castration-resistant prostate cancer. The histological type was mainly classical prostatic acinar adenocarcinoma, including 16 cases (72.7%) with intraductal carcinoma of the prostate (IDC-P). Six cases (27.3%) showed focal neuroendocrine differentiation. Perineural/vascular invasion and extraprostatic extension were seen in 11 cases (50.0%) and 8 cases (36.4%), respectively. The Gleason scores of 19 patients (86.4%) were≥8. IDC-P was more commonly found in patients with BRCA2 germline pathogenic mutation than those with BRCA2 somatic pathogenic mutation, other DRG pathogenic mutation or no-DRG pathogenic mutation ( P=0.002). With a total follow-up time of 189 months, the median overall survival (OS) was 132.3 months. Patients with DRG pathogenic mutation had shorter OS than those with no-DRG pathogenic mutation ( P=0.040). The OS of patients with BRCA2 germline pathogenic mutation did not significantly differ from that of patients with BRCA2 somatic pathogenic mutation, other DRG pathogenic mutation or no-DRG pathogenic mutation ( P=0.216). Conclusions:The presence of BRCA2 gene pathogenic mutation is common in the prostate cancers with high Gleason grade, advanced clinical stage, and castration resistance. IDC-P is more commonly noted in cases with BRCA2 germline pathogenic mutation than those without. Patients with DRG pathogenic mutation have shorter OS than those with no-DRG pathogenic mutation, but there is no significant association between BRCA2 pathogenic mutations and OS.

Conclusion:Glycyrrhetinic acid can correct the shift of Th2 in the immune system of cough variant asthma mice and has a certain therapeutic effect.

Background and purpose:Lung adenocarcinoma has the characteristics of difficult early detection,rapid tumor progression and low surgical resection rate.Although studies on immunotherapy alone and immunotherapy combined with chemotherapy have shown initial success in improving prognosis and overcoming drug resistance,the majority of lung adenocarcinoma patients still receive limited benefits.Therefore,there is an urgent need to identify novel biomarkers with relatively high sensitivity and specificity to improve the prognosis of lung adenocarcinoma.Cell division cycle protein 20(CDC20)is involved in the occurrence and development of various tumors,but its biological role and mechanism in lung adenocarcinoma remain unclear.The aim of this study was to investigate the expression of CDC20 in lung adenocarcinoma and its predictive value for the prognosis of patients with lung adenocarcinoma,and to further explore the effects of CDC20 on the proliferation and invasion capabilities of lung adenocarcinoma cells.Methods:Utilizing immunohistochemistry(IHC)to detect the expression of CDC20 in lung adenocarcinoma tissues,we analyzed its correlation with poor prognosis in combination with bioinformatics and clinicopathological parameters.Kaplan-Meier survival curves were employed to illustrate the impact of CDC20 on postoperative survival rates in lung adenocarcinoma patients.COX multivariate regression analysis was conducted to identify independent prognostic factors influencing postoperative survival rates.Additionally,receiver operating characteristic(ROC)curves were applied to assess the diagnostic value of CDC20 expression in lung adenocarcinoma patients.Real-time fluorescence quantitative polymerase chain reaction(RTFQ-PCR)and Western blot were used to measure the expression levels of CDC20 in normal human lung epithelial cells(BEAS-2B)and human lung adenocarcinoma cells(A549 and H1299).In cellular experiments,CDC20 was knocked down in lung adenocarcinoma cells,which were divided into three groups:si-NC(control group),si-CDC20#1(knockdown group 1)and si-CDC20#2(knockdown group 2).Cell counting kit-8(CCK-8),colony formation,transwell and wound healing assays were conducted to assess cell proliferation,migration and invasion capabilities.Functional enrichment analysis using Geng Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways was conducted to explore the biological roles of CDC20 in lung adenocarcinoma.Finally,gene set enrichment analysis(GSEA)was employed to investigate potential regulatory pathways of CDC20 in lung adenocarcinoma.This study was approved by the Ethics Committee of Hebei Chest Hospital(Number:2022051).Results:The results of both bioinformatics analysis and IHC demonstrated a significantly high expression of CDC20 in lung adenocarcinoma tissues(P＜0.05).Both bioinformatics analysis and clinical parameter evaluation revealed a correlation between high CDC20 expression and poor patient prognosis.Kaplan-Meier survival analysis and COX regression analysis consistently indicated a significant negative correlation between CDC20 expression and postoperative survival rates in patients(P＜0.05).Additionally,the expression levels of CDC20 were higher in human lung adenocarcinoma cell lines A549 and H1299 compared with BEAS-2B(P＜0.05).Knockdown of CDC20 effectively inhibited the proliferation,migration and invasion of lung adenocarcinoma cells(P＜0.05).The results of GO,KEGG pathways and GSEA consistently pointed to a relationship between CDC20 and cell cycle regulation.Conclusion:CDC20 is highly expressed in lung adenocarcinoma.High expression of CDC20 is an independent risk factor for poor prognosis of lung adenocarcinoma patient.CDC20 can promote the proliferation,migration and invasion of lung adenocarcinoma cells.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe₃O₄@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe₃O₄@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe₃O₄@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T₂ magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe₃O₄@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.
