Characterization of gut microbiota based on full-length 16S rRNA gene sequencing in high diamine oxidase population / 中华微生物学和免疫学杂志

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.

Characteristics of gut microbiota in hyperuricemia population based on full-length 16S rRNA sequencing / 中华微生物学和免疫学杂志

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.

Research progress on the relationship between cisplatin ototoxicity and autophagy / 临床耳鼻咽喉头颈外科杂志

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.

Efficacy of autologous fat injection to treat patulous Eustachian tube / 中国耳鼻咽喉头颈外科

OBJECTIVE To explore the efficacy of autologous fat injection of eustachian tube pharyngeal orifice in the treatment of Patulous eustachian tube (PET). METHODS We selected 18 patients who had no obvious improvement after medical treatment of PET over 1 months. They were treated with autologous fat injections to narrow the pharyngeal ostium of the eustachian tube. The treatment results were documented, including the patient's supervisory feeling and visual analogue scale (VAS). RESULTS The total effective rate was 83.3％ after 12 months of follow-up (symptoms significantly reduced in 27.8％ of patients and partial improvement is 55.6％), 16.7％ the symptoms remain unchanged, no one worsened. No patients had any complications. CONCLUSION Autologous fat injection of the eustachian tube is a effective and safe treatment for PET with the percentage of significant or partial relief of 83.3％, It is easy to conduct in clinical practice which could potentially serve as an alternative treatment for PET.

BACKGROUND:Knee society score of Peking Union Medical Col ege has been promoted and used in the 306th Hospital of PLA for 2 years and we have accumulated some clinical data. OBJECTIVE:To analyze the stability and feasibility for suitable clinical medical practice of knee society score of Peking Union Medical Col ege. METHODS:Fifty-five patients with osteoarthritis of the knee were included, and the patients were divided into three groups:the preoperative group;3 months postoperative fol ow-up group;6 months postoperative fol ow-up group. The measurement results obtained by the application of the scale were compared to those of the Western Ontario and McMaster Universityies Ostroarthritis Index, visual analog scale, and hospital for special surgery score, and then knee society score goodness-of-fit analysis was performed based on the structural equation model. RESULTS AND CONCLUSION:Knee society score performance assessment of the signs and symptoms of osteoarthritis of the knee patients was positively correlated with the pain severity of visual analog scale score;the overal knee society score of the patients after 6-month fol ow-up was significantly improved compared with that before treatment. The knee society score after 3-and 6-month fol ow-up was significantly higher than that before treatment, and the score was quite with the hospital for special surgery score. The overal assessment of the knee society score after treated for 3 and 6 months was improved for more than grade Ⅰ, the visual analog scale score was decreased for more than 30%. The pain assessment items and physiological functional assessment items of Western Ontario and McMaster Universityies Ostroarthritis Index after 6-month fol ow-up were significantly better than those before treatment (Pgoodness-of-fit analysis showed that the scale had good goodness which had scientific nature and application value.

Clinical significance of preS1,HBV DNA and HBV-M in patients with chronic hepatitis B / 中国基层医药

Objective To investigate the clinical significance and relationship of preS1, HBV DNA and HBV-M. Methods PreS1 and HBV-M was detected by ELISA method,and HBV DNA was detected by PCR. Then the results were analyzed. Results In HBV patients,the positive rates of preS1 and HBV DNA had no statistically significant ,they had fine dependability. The detection rate of preS1 in HBeAg(+) group(80.3%) and HBeAg(+)group( 56.3% ) had statistically significant. In some patients,though HBeAg had become negative, HBV still replicated. In HBV DNA replicated patients(≥103 copies/ml) ,the detection rate of HBeAg and preS1 were 51.5% and 70.9% ,they had statistically significant. Conclusion HBV DNA and PreS1 had fine dependability,preSl could reflect the replication of HBV sensitively than HBeAg,it could be used as a reliable new marker of HBV replication in vivo.
