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 investigate whether acupoint penetration acupuncture (APA) could regulate chondrocyte autophagy and apoptosis via the PI3K/Akt-mTOR signaling pathway to reduce cartilage degeneration in knee osteoarthritis (KOA) rats. Methods: KOA was induced in rats via intra-articular injection of sodium iodoacetate resolution. Forty male Sprague-Dawley rats were randomly assigned to blank control, model, APA, electro-acupuncture (EA), and sham model groups (n = 8) and those in the APA and EA groups received their respective therapies. Following completion of the treatment course, histological examinations of cartilage and muscle were conducted. Levels of apoptosis- and autophagy-related factors, including Bax, Bcl-2, mTOR, ULK-1, and Beclin-1 protein, and mRNAs were assessed. Additionally, β-endorphin (β-EP) concentrations in the brain and serum were measured. Results: Histological analysis revealed that APA alleviated cartilage and muscle damage compared with the model group. APA inhibited cartilage degeneration by modulating the expression of apoptosis- and autophagy-related proteins and mRNA, thus preventing chondrocyte apoptosis. In the APA group, Bax and mTOR protein levels were significantly lower than those in the model group (both P = .024). Conversely, the Bcl-2 expression level was significantly higher than that in the EA group (P = .035). Additionally, ULK-1 expression was significantly lower than that in the EA group (P = .045). The mRNA level of Bax was significantly higher than that in the blank control group (P < .001). However, Beclin-1 levels were significantly higher than those in both the model and EA groups (both P < .001). ELISA results showed a significant decrease in the concentration of β-EP in the brains of the rats in the APA group compared with those in the model group (P = .032). Conclusions APA reduced osteoarthritis-related pain and alleviated cartilage damage by upregulating chondrocyte autophagy and down-regulating apoptosis via signaling pathways involving PI3K/Akt-mTOR in KOA rats.

Objective To explore the effect and possible pharmacological mechanism of Bufei Tongbi Decoction in the treatment of systemic lupus erythematosus interstitial lung disease (SLE-ILD).Methods The effective components and related targets of Bufei Tongbi Decoction were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Uniprot database. Key genes for SLE-ILD were screened based on DrugBank,DisGeNET,GeneCards,PharmGKB,OMIM,and GEO databases. Using Cytoscape software,a drug active ingredient-target-disease relationship network diagram was constructed to obtain the effective active ingredients and possible mechanisms of action of Bufei Tongbi Decoction in the treatment of SLE-ILD. Gene ontology (GO) function enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used to reveal related target genes and pathway functions. Taking C57BL/6 mice as normal group,MRL/lpr mice were injected with bleomycin 5mg/kg in the nasal cavity. According to the random number table method,the mice were divided into model group,Bufei Tongbi Decoction low-dose group (10.4 g/(kg·d)),Bufei Tongbi Decoction medium-dose group (20.8 g/(kg·d)),Bufei Tongbi Decoction high-dose group (41.6 g/(kg·d)) and prednisone group (3 mg/(kg·d)). The intervention lasted for 28 days. Hematein eosin and Masson staining were used to observe the pathological changes of mouse lung tissue,the expressions of transforming growth factor-β1 (TGF-β1) and collagen type Ⅲ (Col-Ⅲ) in lung tissue were detected by immunohistochemistry,and the expressions of interleukin-1β(IL-1β),interleukin-10 (IL-10) and interleukin-17 (IL-17) in serum were detected by ELISA. The mRNA expressions of matrix metallopeptidase 1(MMP-1),hypoxia inducible factor-1α(HIF-1α),retinoid-related orphan receptor γt (RORγt ) and forkhead box P3 (FOXP3) in lung tissue were analyzed by RT-PCR,the protein expressions of HIF-1α and MMP-1 in lung tissue were detected by Western blotting,and the expressions of T helper 17 cells (Th17) and regulatory T cells (Treg cells) in blood were detected by cytometry.Results A total of 163 effective ingredients,259 targets,1729 SLE-ILD disease targets,958 SLE-ILD differential genes and 40 drug-disease interaction targets were obtained by screening. GO functional enrichment and KEGG pathway enrichment showed that IL-17 signaling pathway activated by IL-1β and MMP-1,and Th17 cell differentiation activated by IL-1β and HIF-1α were the main pathways. Animal experiments showed that Bufei Tongbi Decoction could effectively improve the degree of lung interstitial lesion and reduce the expressions of TGF-β1 and Col-Ⅲ in SLE-ILD mice (P<0.01). The expressions of IL-1β,HIF-1α and IL-17 were decreased (P<0.01). Medium and high doses of Bufei Tongbi Decoction decreased the expressions of MMP-1 and RORγt mRNA (P<0.01),and increased the expressions of IL-10 and FOXP3 mRNA (P<0.01). Bufei Tongbi Decoction could reduce the proportion of Th17 cells,increase the proportion of Treg cells,downregulate the balance of Th17/Treg (P<0.05),and improve the immune disorder. Conclusion Bufei Tongbi Decoction has the characteristics of multi-target and multi-pathway in treating SLE-ILD,and its mechanism may be related to the regulation of Th17/Treg cell balance.

Objective To observe the clinical safety and efficacy of foscarnet prophylaxis and pre-emptive therapy for cytomegalovirus (CMV) infection in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Ninety-six patients undergoing allo-HSCT from October 2014 to December 2016 were retrospectively analyzed. Plasma CMV-DNA was monitored with real-time quantitative polymerase chain reaction (RQ-PCR) from beginning to 180 days after transplantation. Foscarnet was used not only for prophylaxis but also for first-line pre-emptive therapy when plasma CMV-DNA turned to positive. Foscarnet was given 60 mg·kg-1·d-1 and 120 mg·kg-1·d-1 respectively in prevention and pre-emptive therapy. Incidences of CMV infection and CMV disease were observed, influencing factors on CMV in faction and the efficacy and safety of foscarnet prophylaxis were analyzed, and survival of patients treated by all-HSCT was evaluated. Results Of the total 96 patients, 42 cases (43.8%) had CMV infection with the median time of 42 days after allo-HSCT. CMV-DNA became negative in 36 patients (85.7%, 36/42) after pre-emptive therapy. Six patients (14.3 %, 6/42) developed CMV disease, including 5 patients with CMV negative and 1 patient died for CMV pneumonia. Haploidentical donor and grade Ⅱ-Ⅳacute graft versus host disease (GVHD) were the risk factors for CMV reactivation (χ2 = 3.834, P< 0.05; χ2 = 16.807, P< 0.001). The side effects of foscarnet prophylaxis were mild without hematologic toxicities. 12 patients (28.6 %) died in 42 patients with CMV infection, and 6 patients (11.1 %) died in 54 patients without CMV infection. The difference of survival rates between both groups was not statistically significant. Conclusion Foscarnet is an effective agent for prophylaxis and pre-emptive therapy in CMV infection after allo-HSCT with mild adverse reactions, especially for patients following with hematopoietic recovering.
