ABSTRACT

Objective:To investigate the correlation between gut microbiota and serum diamine oxidase (DAO) level and to analyze the differences in gut microbiota between high DAO (DAO-H) and normal DAO populations.Methods:This study recruited 62 adult volunteers (31 in DAO-H group and 31 in normal control group) taking health examination in the Strategic Support Forces Special Medical Center in 2021. Their stool samples were collected to analyze the composition of gut microbiota in the two populations by full-length 16S rRNA gene sequencing.Results:No significant difference in the alpha diversity of gut microbiota was found between the DAO-H group and the normal control group, but the structure and function of gut microbiota varied. In the DAO-H group, commensal bacteria decreased, such as Phocaeicola and Bacteroidetes, while potential pathogenic bacteria increased, such as Klebsiella pneumoniae. There were changes in the metabolism of gut microbiota in the DAO-H group, including inhibited sphingolipid metabolism and enhanced biosynthesis of vancomycin group antibiotics, one carbon pool by folate pathway, terpenoid backbone biosynthesis, cell cycle-Caulobacter, protein export, base excision repair and nitrogen metabolism.Conclusions:Compared with the people with normal DAO, the population with high DAO had unique characteristics in gut microbiota composition and metabolism.

ABSTRACT

Objective:To analyze the differences in gut microbiota between patients with hyperuricemia (HUA) and healthy population for better understanding the correlation between gut microflora and high uric acid.Methods:This study recruited 63 adult volunteers, including 25 HUA patients (HUA group) and 38 healthy people (control group), who underwent physical examination in the PLA Strategic Support Force Characteristic Medical Center in 2021. Their fecal samples were collected and analyzed by 16S rRNA high-throughput full-length gene sequencing to analyze the composition of gut microbiota.Results:The overall composition of gut microbiota was different between HUA group and control group. The α diversity index decreased significantly in HUA group and β diversity analysis showed that there were significant differences between the two groups. HUA group showed increased Bacteroidetes and decreased Firmicutes. LEfSe analysis indicated a unique microbiota structure in HUA group, characterized by significantly decreased short-chain fatty acid (SCFA)-producing bacteria represented by Faecalibacterium prausnitzii and significantly increased Streptococcus salivarius, Bacteroides fragilis, Fusobacterium hwasookii, Flavonifractor plautii, Mycobacterium mucogenicum B and Blautia sp003287895. In addition, functional prediction through PICRUSt2 showed that the metabolism related to gut microbiota SCFA pathway in HUA group was decreased, which was consistent to the unique microbiota structure. Conclusions:Compared with healthy population, patients with hyperuricemia had different composition of gut microbiota and metabolic feature.

ABSTRACT

Summary@#Cisplatin is an anti-tumor drug which is widely used for the treatment of various solid tumors. Unfortunately, seriousside-effects have affected patients, such as hearing loss. Up to now, there is no clear and effective measure to protect the cisplatin-induced ototoxicity in the clinical use of cisplatin studies indicated that autophagy may be involved in the whole process of cisplatin-induced hearing loss. In this review, the relationship between cisplatin ototoxicity and autophagy was reviewed. It is hoped that this study can provide reference for further study of cisplatin ototoxicity and intervention of autophagy with autophagy activator or inhibitor.
