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 comprehensively analyze the effectiveness， safety and economic value of carfilzomib in the treatment of multiple myeloma （MM）， and provide evidence-based guidance for clinical rational drug use. METHODS A systematic search was performed in PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP， and relevant health technology assessment （HTA） websites， from database inception to December 31， 2024. Two researchers independently screened studies based on predefined inclusion and exclusion criteria， extracted data， and assessed study quality. Descriptive statistical analyses were conducted. RESULTS A total of 21 studies were included， comprising 7 systematic reviews/meta-analyses， 5 clinical trials， 5 pharmacoeconomic studies， and 4 HTA reports. Effectiveness analysis indicated that， compared with control groups， carfilzomib significantly improved overall response rate and clinical benefit rate （ P ＜0.05）， prolonged progression-free survival， and enhanced patient’s quality of life （ P ＜0.05）， while its impact on overall survival remains to be further confirmed. Safety analysis showed there was no significant difference in the risk of peripheral neuropathy between carfilzomib and controls， while the risks of cardiotoxicity and hypertension were significantly increased （ P ＜0.05）. Economic analysis suggested that carfilzomib regimens demonstrated certain cost-effectiveness in second-line treatment in the U.S. and some European countries. However， its economic value was influenced by drug price， dosing regimen， and regional differences， and it may lack a cost advantage in some countries or in third-line treatment. CONCLUSIONS Carfilzomib shows definite efficacy and generally acceptable safety in the treatment of MM， but cardiotoxicity and hypertension risks require careful monitoring. Given its high treatment cost， pharmacoeconomic studies in the Chinese population are urgently needed.

ObjectiveTo observe the effects of Xiere Xingpi Yin （XRXPY） on the body mass and body fat distribution in patients with simple obesity， and to preliminarily explore whether the mechanism involves the regulation of specific obesity-related microRNAs （miRNAs）. MethodsA randomized controlled trial design was employed to recruit patients with simple obesity diagnosed with the traditional Chinese medicine （TCM） syndrome of dampness-heat accumulating in the spleen. Using a randomized controlled trial design， 95 patients with simple obesity of dampness-heat encumbering the Spleen syndrome were recruited， after 3 were excluded， 92 were randomly assigned in a 1∶1 ratio by means of a random number table. On the basis of lifestyle intervention， the observation group received XRXPY granules， while the control group received a placebo. Serum samples and TCM symptom scores were collected before and after the 12-week observation period. Differences in body mass loss， body composition， lipid metabolism， and TCM symptom scores were compared between the groups. An obesity-related miRNA dataset was constructed by searching the Human MicroRNA Disease Database. Library construction， sequencing， and quality control were performed on 6 selected patients from each group to screen the differentially expressed miRNAs. The intersection of these miRNAs with the obesity-related miRNAs was verified by bioinformatics and correlation analysis. ResultsBaseline characteristics were comparable between the two groups before treatment. A total of 86 patients completed the study （42 cases in the observation group and 44 cases in the control group）. The proportion of patients achieving ≥5% body weight reduction was significantly higher in the observation group than in the control group 81.0% （34/42） vs. 43.2% （19/44） （χ²=12.963， P<0.01）. Compared with baseline within the observation group， body weight， waist circumference， and TCM syndrome score were significantly decreased （P<0.01）， as were body fat percentage （P<0.01） and serum triglyceride level （P<0.05）. Compared with the control group after treatment， waist circumference and TCM syndrome score were significantly lower in the observation group （P<0.01）， and body weight showed a trend toward reduction. When changes from baseline were compared between the two groups， the magnitudes of decrease in body weight， waist circumference， and TCM syndrome score were all significantly greater in the observation group than in the control group （P<0.01）. With respect to safety， no serious adverse events occurred in either group and no participant discontinued the study because of adverse events. Compared with baseline， alanine aminotransferase levels decreased significantly in both the control and observation groups （P<0.01）， and urea decreased significantly in the observation group （P<0.01）， indicating a favorable safety profile. Sequencing identified nine differentially expressed miRNAs. After intersecting with the obesity-related miRNA dataset （187 miRNAs）， 3 miRNAs were identified： miR-221 （log₂FC=-6.62， P=0.009）， miR-29a （log₂FC=6.33， P=0.016）， and miR-10b （log₂FC=-5.91， P=0.029）. A total of 262 target genes of the 3 miRNAs were identified， which were significantly enriched in 67 pathways， including the lysine degradation pathway （P=0.001）. Correlation analysis revealed a positive correlation between miR-221 and triglycerides （r=0.46， P=0.027）， a negative correlation between miR-29a and waist-to-hip ratio （r=-0.41， P=0.047）， and positive correlations of miR-10b with body fat percentage （r=0.49， P=0.014） and waist circumference （r=0.44， P=0.032）. ConclusionXRXPY combined with lifestyle intervention can effectively reduce the body mass and improve body composition. The underlying mechanism may involve the regulation of the lysine degradation pathway via miR-221， miR-29a， and miR-10b， though further verification is required.

ObjectiveTo investigate the inhibitory effect of tauroursodeoxycholic acid （TUDCA） on neurogenic heterotopic ossification （NHO） after spinal cord injury and its potential mechanism. MethodsSPF-grade male C57BL/6 mice were used to establish an NHO model. The mice were randomly divided into three groups： sham operation group （laminectomy only）， NHO model group （spinal cord injury + intramuscular injection of cardiotoxin）， and TUDCA treatment group （NHO model + daily intragastric administration of TUDCA at 200 mg/kg for 4 consecutive weeks）. The area and maturity of heterotopic ossification were quantitatively assessed by micro-computed tomography（micro-CT） and hematoxylin-eosin（H&E） staining. Flow cytometry was used to quantify the interleukin（IL）-1β secretion level of M2 macrophages. RAW264.7 macrophages were cultured in vitro and divided into control， tumor necrosis factor（TNF）α， and TNFα+TUDCA （200 μmol/L） groups to detect the expression level of the polarization marker CD206. Additionally， macrophages were divided into control， TUDCA 200 μmol/L， and TUDCA 400 μmol/L groups to assess the IL-1β secretion level. ResultsCompared with the NHO group， the bone volume in the TUDCA-treated group was significantly reduced （12.69±1.13 vs. 7.647±1.19， P=0.003）. Compared with the TNFα group， qPCR results showed that the expression of the M2 macrophage marker CD206 was significantly upregulated in the TNFα+TUDCA group （0.55±0.019，1.11±0.023， P＜0.001）. Compared with the control group， ELISA results showed that TUDCA stimulation of macrophages significantly upregulated IL-1β secretion （404.7±24.38 vs. 652.8±32.61， P=0.003 7）. TUDCA administration upregulated IL-1β secretion by local muscle macrophages and inhibited heterotopic ossification formation. ConclusionsTUDCA might participate in inhibiting NHO formation by inducing M2 macrophage polarization and upregulating IL-1β secretion， thereby alleviating the development and progression of neurogenic heterotopic ossification after spinal cord injury. This finding provides experimental evidence for expanding the application of TUDCA in the treatment of complications following spinal cord injury.

Background:Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials.Microbial agents,as environmentally friendly and efficient plant growth promoters and soil conditioners,have increasingly attracted attention in eco-agriculture research.Objective:Our understanding remains limited regarding how the application of microbial agents,alone or in combination,affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials.Methods:In this study,Epimedium pubescens Maxim.was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis)applied individually and in combination on plant growth and the accumulation of bioactive components.Additionally,this study explored the relationship between the rhizosphere microbiome and plant development.Results:The application of microbial agents increased the yield of E.pubescens leaves by 20.30％to 33.66％and enhanced the total flavonol glycosides content by 11.40％to 29.94％.Meanwhile,microbial treatments reshaped the rhizosphere microbiome,promoted the enrichment of beneficial microorganisms(e.g.,Frankia and Paenibacillus),suppressed phytopathogenic fungi such as Didymella and Scytalidium,and enhanced the stability of the soil microbial co-occurrence network.The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumula-tion of bioactive components by modulating the soil microbiome.Conclusion:These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere micro-biomes as mediated by microbial agents.They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture.

Objective To investigate the influencing factors associated with the risk of positive methylation levels of SHOX2/RASSF1A/PTGER4 genes in patients with pulmonary nodules with TCM susceptibility.Methods Using a cross-sectional study method,totally 165 patients with pulmonary nodules from the Respiratory Department of Wangjing Hospital,China Academy of Chinese Medical Sciences were included from May 2024 to December 2024.Clinical data such as patients'general medical history,nodule imaging reports,lung cancer gene methylation levels,and TCM constitution assessments were organized and statistically analyzed.On the basis of exploring the correlation between various variables and the risk of positive methylation of lung cancer genes through univariate correlation analysis,a binary logistic regression model was used for independent risk factor analysis.Results Univariate correlation analysis showed that age,gender,TCM susceptibility score,diameter of pulmonary nodules and upper lobe of the right lung were correlated with positive methylation levels of the SHOX2/RASSF1A/PTGER4 genes(P=0.03,P=0.02,P=0.01,P<0.01,P=0.03);and binary Logistic regression analysis showed that yang-deficiency quality,qi deficiency,qi depression and phlegm-dampness,the four pulmonary nodules susceptibility body scores were significantly and positively correlated with the risk of SHOX2/RASSF1A/PTGER4 gene methylation positivity.Compared with yang deficiency,phlegm-dampness and qi depression had a higher risk of gene methylation positivity for patients with pulmonary nodules(P=0.04,P=0.02).Conclusion Older age,males,and TCM susceptibility body correlated with the lung cancer gene methylation positive risk are correlated,in which phlegm dampness and qi depression are independent risk factors.

Compared with the TBI group ([247.20±9.88] cells/mm 2), the TBI+10 mg/kg NSA group had significantly decreased number of Iba-1 +Caspase-1 p20 + cells in the injured parietal cortex ([181.70±9.37] cells/mm 2, P<0.05). (2) Compared with the LPS+ATP+DMSO group, the LPS+ATP+5 μmol/L NSA group, LPS+ATP+10 μmol/L NSA group, and LPS+ATP+15 μmol/L NSA group had decreased IL-18 content in the supernatant, successively, with significant differences ( P<0.05); and compared with the LPS+ATP+DMSO group, the LPS+ATP+10 μmol/L NSA group and LPS+ATP+15 μmol/L NSA group had significantly decreased contents of LDH, IL-1β, and TNF-α in the supernatant and ratio of PI +/CAM + cell counts ( P<0.05). Compared with the LPS+ATP+DMSO group (2.62±0.50), the LPS+ATP+10 μmol/L NSA group and LPS+ATP+15 μmol/L NSA group had significantly decreased Caspase-1 p20 protein expression (1.36±0.14, 1.32±0.07, P<0.05). Compared with the LPS+ATP+DMSO group (5.00±1.67), the LPS+ATP+5 μmol/L NSA group and LPS+ATP+15 μmol/L NSA group had significantly decreased GSDMD protein expression (1.42±0.26, 1.68±0.32, P<0.05). Compared with the LPS+ATP+DMSO group (2.28±0.24), the LPS+ATP+15 μmol/L NSA group had significantly decreased GSDMD-N protein expression (1.23±0.08, P<0.05). Conclusion:NSA can inhibit microglial pyroptosis after TBI by inhibiting the Caspase-1 p20/GSDMD pathway, thereby playing a neuroprotective role.
