Meniere's disease represents an idiopathic inner ear disorder characterized by endolymphatic hy-drops.Currently,the research methods for identifying genes associated with this disease mainly involve first-genera-tion sequencing and second-generation sequencing.This article reviews research on the genetic study of Meniere's disease,mainly summarizing the candidate genes with repeated pedigree validation in familial Meniere's disease,as well as those frequently reported in sporadic Meniere's disease.

Sennoside A(SA),a typical prodrug,exerts its laxative effect only after its transformation into rhei-nanthrone catalyzed by gut microbial hydrolases and reductases.Hydrolases have been identified,but reductases remain unknown.By linking a photoreactive group to the SA scaffold,we synthesized a photoaffinity probe to covalently label SA reductases and identified SA reductases using activity-based protein profiling(ABPP).From lysates of an active strain,Bifidobacterium pseudocatenulatum(B.pseu-docatenulatum),397 proteins were enriched and subsequently identified using mass spectrometry(MS).Among these proteins,chromate reductase/nicotinamide adenine dinucleotide(NADH)phosphate(NADPH)-dependent flavin mononucleotide(FMN)reductase/oxygen-insensitive NADPH nitroreductase(nfrA)was identified as a potent SA reductase through further bioinformatic analysis and The Universal Protein Resource(UniProt)database screening.We also determined that recombinant nfrA could reduce SA.Our study contributes to further illuminating mechanisms of SA transformation to rheinanthrone and simultaneously offers an effective method to identify gut bacterial reductases.

Objective:To investigate the change of cortical activation pattem during wrist extension in health subjects in-duced by neuromuscular electrical stimulation(NMES)and peripheral magnetic stimulation(PMS),using func-tional near infrared spectroscopy(fNIRS).Method:Fifteen health adults received 2 randomly ordered interventions(NMES and PMS),which were applied to the dominant wrist extensor muscle to induce wrist extention.Qxy-hemoglobin(HbO2)and deoxygenated he-moglobin(HbR)were measured in seven regions of interest(ROI)during NMES and PMS stimulation.The difference between these two non-invasive peripheral stimulation on the cortical activation was recorded in the changes of HbO2 and HbR concentrations.Result:During NMES motor phase,HbO2 values of 38 channels in ROI except bilateral S1 region showed a significant decreased compared with the rest period(P＜0.05).The HbO2 values of six channels were significant-ly changed in PMS motor phase,and the activated channels were concentrated on M1 region.The HbO2 val-ues of the left M1 region of hand movement area(channel 35)were higher than other ROI(P＜0.05).The acti-vation of HbO2 in the left M1 hand movement area(channels 23 and 35)was significantly stronger in PMS motor phase than in NMES motor phase(P＜0.05).Based on HbR values,both NMES and PMS activated the same number of channels compared to the rest period.Conclusion:The results showed that NMES induced wrist extension could lead to decreased cortical activation in multiple brain regions,and PMS induced more concentrated and effective cortical activation than NMES.PMS likely via massive inflows of'pure'proprioceptive information.Both PMS and NMES can increase the stimulation of functional activity in parts of muscle-innervated cortex based on changes in HbO2 values,with PMS stimulating cortical functional activity regionally.
