Dry eye disease(DED)is a multifactorial disorder with an unclear pathogenesis. Advances in omics technologies have introduced a novel medical research approach, enabling the identification of global response variables from a single-factor perspective. However, multi-omics methods integrate multiple omics datasets to analyze all potential response variables, generating multidimensional and evidence-supported holistic inferences. These insights help elucidate functional impairments of ocular cells and biomolecular processes during disease progression, thereby revealing correlations between biomolecules and complex diseases. This review summarizes the application of multi-omics technologies in clarifying the pathogenesis and intricate molecular mechanisms of dry eye disease. Distinctive features from genomics, transcriptomics, proteomics, metabolomics, and microbiomics are integrated to deepen the understanding of the pathogenesis and complex molecular mechanisms underlying dry eye disease.

Objective To explore the optimization strategy of Qishen Granules in treating coronary heart disease with heart failure(CHD-HF)based on data mining and the pathogenic"toxin"theory,and to predict its active components and mechanisms using network pharmacology.Methods Literature on traditional Chinese medicine(TCM)for treating CHD-HF was collected from relevant databases,and prescriptions were screened and established into a database according to inclusion and exclusion criteria.Frequency,association rules,and hierarchical clustering analyses were performed using the Ancient and Modern Medical Case Cloud Platform.Network pharmacology techniques were applied to screen potential targets of the optimized combination for treating CHD-HF,and carry out the targets and pathways enrichment analysis.Results A total of 336 articles and 339 prescriptions involving 191 herbs were included,with 12 herbs used more than 100 times.The core drug combinations for treating CHD-HF included Astragali Radix,Poria,Salviae Miltiorrhizae Radix et Rhizoma,Glycyrrhizae Radix et Rhizoma,Chuanxiong Rhizoma,etc,while commonly used detoxifying herbs included Leonuri Herb,Coptidis Rhizoma,etc.Association rule analysis yielded 10 two-item associations and 17 three-item associations;clustering analysis grouped the data into 5 categories.Based on data mining and the pathogenic"toxin"theory,the combination for treating CHD-HF was optimized to include Astragali Radix,Salviae Miltiorrhizae Radix et Rhizoma,Aconiti Lateralis Radix Praeparata,Glycyrrhizae Radix et Rhizoma,Coptidis Rhizoma,and Taraxaci Herba.Network pharmacology analysis identified 366 common targets between the optimized combination and CHD-HF,with 16 core targets screened out.Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis revealed significant enrichment in pathways such as cancer pathways,lipid and atherosclerosis,Rap1 signaling pathway,hypoxia-inducible factor 1(HIF-1)signaling pathway,phosphatidylinositol-3-kinase/protein kinase B(PI3K/Akt)signaling pathway,Ras signaling pathway,and mitogen-activated protein kinase(MAPK)signaling pathway.Conclusion TCM treatment for CHD-HF primarily focuses on replenishing qi and warming yang,activating blood circulation and resolving fluid retention.Based on data mining results and the pathogenic"toxin"theory,the formulation strategy of Qishen Granules for treating CHD-HF was optimized,potentially exerting therapeutic effects through anti-inflammatory,anti-apoptotic,and anti-hypoxia physiological processes.

Malignant insulinoma is a kind of rare and challenging neuroendocrine tumor. It is often accompanied by distant metastasis, among which liver metastasis is most common, and the prognosis is often non-promising. In this paper, we report a case of multiple liver metastases from malignant insulinoma. The patient, a 70-year-old male, was admitted to the hospital due to "episodic consciousness disorder for more than four months." Blood glucose monitoring revealed recurrent hypoglycemia in the early morning, after meals, and at night. Pancreatic perfusion CT and dynamic enhanced MRI of the liver revealed a mass in the uncinate process of the pancreatic head and multiple liver metastases. Percutaneous liver biopsy confirmed the diagnosis of insulinoma. After multidisciplinary discussions, hepatic artery embolization and radiofrequency ablation were performed in stages, in combination with everolimus treatment. Thereafter, the enhanced CT demonstrated that some liver metastases shrank. The patient had regular meals, and the blood sugar gradually increased and remained normal thereafter. This article discusses this case's clinical characteristics and multidisciplinary collaborative diagnosis and treatment, aiming to provide experience for the comprehensive clinical diagnosis and treatment of malignant insulinoma patients.

Objective:To compare the clinical efficacy of neoadjuvant chemoradiotherapy (nCRT) and neoadjuvant chemo-immunotherapy (nCIT) for locally advanced esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of patients who received nCRT or nCIT followed by esophagectomy for locally advanced ESCC between January 2010 and December 2022 were retrospectively collected from Zhejiang Cancer Hospital, with 155 patients in the nCRT group and 470 patients in the nCIT group. Propensity score matching (PSM) was performed in the two groups. After PSM, 120 patients were allocated to the nCRT group and 192 patients to the nCIT group. The pathological response and disease recurrence were compared between the two groups after PSM. Log rank test were used to compare the survival outcomes before and after PSM. Univariate and multivariate Cox regression analyses were performed to identify the prognostic factors for locally advanced ESCC.Results:After PSM, the R0 resection rate in the nCRT group and the nCIT group was 93.3% (112/120) and 93.8% (180/192), respectively, with no statistical significance ( P=0.884). However, the pathological complete response rate in the nCRT group [36.7% (44/120)] was higher than that in the nCIT group [21.4% (41/192), P=0.003]. For patients with R0 resection, the major recurrence pattern was distant metastasis [18.8% (21/112)] in the nCRT group, while the pattern was locoregional recurrence [12.2% (22/180)] in the nCIT group. The 3-year disease-free survival rates were 52.7% and 66.1% ( P=0.022) and the 3-year overall survival rates were 59.2% and 75.5% ( P=0.002) in the nCRT and nCIT groups, respectively. Multivariate Cox regression analysis also revealed that the neoadjuvant therapy mode was an independent prognostic factor for patients with locally advanced ESCC. Compared with nCRT, nCIT could significantly prolong disease-free survival ( HR=0.58, 95% CI: 0.40-0.86) and overall survival ( HR=0.53, 95% CI: 0.35-0.79). Conclusion:These results suggest that nCIT could significantly improve disease-free survival rate and overall survival rate over nCRT in locally advanced ESCC, even with lower pathological complete response rate.
