Vitiligo is an acquired depigmentation skin disease characterized by depigmentation patches formed by the loss of epidermal melanocytes,which seriously affects the physical and mental health of patients.The pathogenesis of vitiligo has not yet been elucidated,mainly related to factors such as genetics,oxidative stress,autoimmunity,inflammatory response,and neurotransmitters.In recent years,with the in-depth study of the pathogenesis of vitiligo and the improvement of epidemiological data,some scholars be-lieve that vitiligo is not only a skin disease that affects beauty,but also may be related to metabolic disorders.Vitiligo is often accompa-nied by metabolic diseases such as obesity,dyslipidemia,abnormal glucose tolerance,diabetes and hypertension.Vitiligo patients with metabolic diseases limit their treatment options,increase the risk of drug interactions,and even increase mortality.At present,the pathogenesis of metabolic diseases in vitiligo patients is not clear.This article reviews the relationship between vitiligo and metabol-ic diseases,which can help in early clinical diagnosis and prevent the occurrence of metabolic diseases.

Objective:To study the changes in serum small molecule metabolites after brucella infection in humans using untargeted metabolomics methods, and screening representative biomarkers. Methods:A total of 109 serum samples collected from January 2019 to December 2021 at the Brucellosis Clinic of the Baotou Center for Disease Control and Prevention were divided into acute phase group ( n = 40), chronic phase group ( n = 35) of brucellosis, and healthy group ( n = 34) based on clinical diagnosis. Ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry technology was used to test serum samples and screen for differential metabolites. Receiver operating characteristic curve was used to evaluate the predictive ability of differential metabolites for brucellosis. Enriched pathways were screened using Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway to identify metabolic pathways significantly affected. Results:A total of 17 differential metabolites were screened between the acute phase group and the healthy group, and 12 differential metabolites were screened between the chronic phase group and the healthy group. There were a total of 5 differential metabolites (oleamide, linoleamide, stearamide, palmitoleic acid, α-linolenic acid) statistically significant among the three groups ( F = 16.84, 17.52, 14.31, 13.01, 20.76, P < 0.05). KEGG pathway analysis showed that the differential metabolites in the acute phase group were enriched in metabolic pathways such as ether lipid metabolism, glycerophosphate metabolism, sphingolipid signal and sphingolipid metabolism. The differential metabolites in the chronic phase group were enriched in metabolic pathways such as glycerophosphate metabolism, ether lipid metabolism, protein digestion and absorption metabolism. Conclusion:Untargeted metabolomics methods can screen out serum small molecule metabolites that undergo changes after brucella infection in the human body, including oleamide, linoleamide, stearamide, palmitoleic acid, α-linolenic acid can serve as potential biomarkers to distinguish brucellosis patients from healthy people.

Objective:To observe the detrimental effect of airborne black carbon suspension solution of different concentrations on the tear film function of mice.Methods:Twenty-eight SPF-grade male BALB/c mice, aged 6-8 weeks, were randomly divided into four groups, 0.5 mg/ml group, 1 mg/ml group, 5 mg/ml group, and control group, with 7 mice in each group.The right eyes of mice were dropped by 4 μl of 0.5 mg/ml, 1 mg/ml, 5 mg/ml black carbon suspension, or phosphate buffer solution, 3 times a day according to grouping.Tear volume, tear break-up time (TBUT), corneal fluorescein staining (CFS), and conjunctival congestion were assessed before treatment and 4, 7, 10, and 14 days after treatment.The use and care of experimental animals complied with the Regulations for Administration of Laboratory Animals in Peking Union Medical College Hospital (No.XHDW-2022-053).Results:At 14 days after treatment, the tear volumes of 0.5 mg/ml group, 1 mg/ml group, 5 mg/ml group and control group were (2.74±0.74), (2.73±0.76), (2.31±0.67), and (5.31±0.36)mm, respectively.TBUT of the four groups were (4.87±0.28), (4.00±0.76), (3.23±0.43), and (6.22±0.22)seconds, respectively.CFS of the four groups were 4(3, 4), 5(5, 6), 7(7, 8) and 0(0, 1) points, respectively.Conjunctival congestion grades of the four groups were 2(2, 3), 2(2, 3), 3(2, 3) and 0(0, 1), respectively.There were statistically significant differences in tear volume among the four groups at different time points ( Fgroup=83.325, P<0.001; Ftime=86.551, P<0.001; Finteraction=5.181, P<0.001). Before and at each time point after treatment, tear volumes were significantly lower in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group than in control group, and tear volumes in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group were significantly lower at 4, 7, 10, and 14 days after treatment than before treatment (all at P<0.05). There were statistically significant differences in TBUT among the four groups at different time points ( Fgroup=75.130, P<0.001; Ftime=56.265, P<0.001; Finteraction=6.103, P<0.001). Before and at each time point after treatment, TBUT was significantly shorter in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group than in control group, and the TBUT was significantly shorter in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group at 4, 7, 10, and 14 days after treatment than before treatment, shorter in 1 mg/ml group and 5 mg/ml group at 14 days after treatment than 4, 7 and 10 days after treatment (all at P<0.05). There were statistically significant differences in CFS score and conjunctival congestion grades among the four groups at different time points, but the interactions between concentration group and measurement time were not statistically significant (CFS: Hgroup=59.249, P<0.001; Htime=49.959, P<0.001; Hinteraction=15.980, P=0.192.conjunctival congestion grade: Hgroup=57.622, P<0.001; Htime=42.062, P<0.001; Hinteraction=12.565, P=0.401). Before and at each time point after treatment, the CFS scores and conjunctival congestion grades were significantly higher in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group than in control group, and CFS scores and conjunctival congestion grades were significantly higher in 0.5 mg/ml group, 1 mg/ml group, and 5 mg/ml group at 4, 7, 10, and 14 days after treatment than before treatment (all at P<0.05). Conclusions:The exposure of airborne black carbon on the ocular surface causes damage to tear film function and ocular surface inflammation in BALB/c mice.Within a certain concentration and time range, the tear secretion decreases, TBUT shortens, CFS and conjunctival congestion increase.
