Objective:We performed a Mendelian randomisation (MR) analysis to explore the relationship between serum metabolites and tinnitus.Methods:In this study, 486 serum metabolites were considered as exposure factors, and single nucleotide polymorphisms (SNP) significantly associated with them were used as instrumental variables (IV). The serum metabolite data were obtained from a public database ( http://metabolomips.org/gwas/index.php), while the genome-wide association study (GWAS) summary association statistics for tinnitus were obtained from a Finnish database ( https://r10.finngen.fi/pheno/H8_TINNITUS). The inverse variance weighting (IVW) method was employed as the primary determination method for MR analysis, with corrections for multiple comparisons made using the false discovery rate (FDR). Sensitivity tests were conducted using the MR-Egger regression, Mendelian random polymorphism residuals and outliers (MR-PRESSO) methods. The identified serum metabolites were subjected to chained disequilibrium regression analysis (LDSC) and metabolic pathway analysis. Reverse MR analysis was performed to investigate the possibility of reverse causality. Analyses were performed in R software (version 4.3.1). Results:A total of 17 serum metabolites (including 10 known and 7 unknown metabolites) associated with tinnitus were identified. The known metabolites included protective metabolites such as acetylcarnitine, hydroxyisovaleryl carnitine, glycine, monounsaturated glycerol ester, and glycine-L-valine, and hazardous metabolites such as allantoin, glycerylphosphorylcholine 1-eicosatrienoate, myo-inositol, 15-methylpalmitate, and pseudouridine; the strongest causally protective metabolites were acetylcarnitine, the followed by hydroxyisopentanoyl carnitine and glycine; the hazardous metabolite with the strongest causal effect was pseudouridine, followed by inositol and 15-methylpalmitate; and only hydroxyisopentanoyl carnitine ( PFDR=0.04) and glycerol monooleate ( PFDR=0.04) reached significance values after FDR correction. The findings were free of heterogeneity, pleiotropy and reverse causal associations. The metabolic pathways were mainly enriched in pathways such as ascorbic acid and aldolac metabolism. Conclusions:The study suggests a causal relationship between serum metabolites and tinnitus risk. Serum metabolite levels may influence tinnitus-related metabolic pathways.

Objective To investigate the mechanisms that mediate the neuroprotective effect of the intestinal microbial metabolite sodium butyrate(NaB)in a mouse model of Parkinson's disease(PD)via the gut-brain axis.Methods Thirty-nine 7-week-old male C57BL/6J mice were randomized equally into control group,PD model group,and NaB treatment group.In the latter two groups,PD models were established by intraperitoneal injection of 30 mg/kg 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)once daily for 5 consecutive days,and normal saline was injected in the control group.After modeling,the mice received daily gavage of NaB(300 mg/kg)or an equal volume of saline for 14 days.Behavioral tests were carried out to assess the changes in motor function of the mice,and Western blotting was performed to detect the expressions of tyrosine hydroxylase(TH)and α-synuclein(α-syn)in the striatum and nuclear factor-κB(NF-κB),tumor necrosis factor(TNF-α),interleukin 6(IL-6),and the tight junction proteins ZO-1,Occludin,and Claudinin the colon.HE staining was used to observe inflammatory cell infiltration in the colon of the mice.RNA sequencing analysis was performed to identify the differentially expressed genes in mouse colon tissues,and their expressions were verified using qRT-PCR and Western blotting.Results The mouse models of PD with NaB treatment showed significantly increased movement speed and pulling strength of the limbs with obviously upregulated expressions of TH,Occludin,and Claudin and downregulated expressions of α-syn,NF-κB,TNF-α,and IL-6(all P<0.05).HE staining showed that NaB treatment significantly ameliorated inflammatory cell infiltration in the colon of the PD mice.RNA sequencing suggested that Bmal1 gene probably mediated the neuroprotective effect of NaB in PD mice(P<0.05).Conclusion NaB can improve motor dysfunction,reduce dopaminergic neuron loss in the striatum,and ameliorate colonic inflammation in PD mice possibly through a mechanism involving Bmal1.

The ABRACL protein, the regulator of actin and cell motility, belongs to the HSPC280 family, and its conserved hydrophobic groove can interact with other proteins to facilitate actin motility and cellular activity. ABRACL is upregulated in tumor tissues and is closely linked with the proliferation and migration of tumor cells. A deeper understanding of the role of ABRACL in tumorigenesis and development may provide new ideas and insights for ABRACL to prevent or reverse tumor progression.

Eyelid tumor is a serious eye disease that leads to vision loss or even blindness.The similarity between benign and malignant characteristics makes it difficult for ophthalmologists lacking clinical experience to distinguish between them.To address the problem,a method(ResNet101_CBAM)based on two-stage target localization using fully convolutional one-stage object detection(FCOS)and residual network incorporating a dual attention mechanism is proposed to realize the automatic diagnosis of benign and malignant eyelid tumors.FCOS is used to automatically localize the overall contour of the orbit,removing the background and surrounding noise,and then finely localize the tumor lesion inside the orbit.The obtained lesion region is input into ResNet101_CBAM for the automatic diagnosis of benign and malignant eyelid tumors.The experimental results show that the average precision of the target localization algorithm for tumor lesion is 0.821,and that compared with ResNet101,ResNet101_CBAM improves the sensitivity and accuracy in eyelid tumor classification by 4.7%and 3.0%,respectively,indicating that the proposed model has superior performances in the automatic diagnosis of benign and malignant eyelid tumors.
