Objective To investigate the effects of DNA demethylation drugs combined with histone deacetylase in-hibitors on fragile X mental retardation 1 neighbor protein (FMR1NB) expression and its promoter methylation in human oral cancer cells and try to find a strategy of weakening the heterogeneity of FMR1NB expression.Methods Human oral cancer cell lines Cal27 and SCC-9 were treated with decitabine (DAC) , an inhibitor of DNA meth-yltransferase, combined with trichostatin A (TSA) and valproic acid (VPA), inhibitors of histone deacetylase.Then reverse transcription-polymerase chain reaction (RT-PCR) , quantitative real-time PCR (qRT-PCR) and Western blot were used to detect the expression of FMR1 NB and pyrosequencing was used to detect the methylation of FMR1NB promoter.Results Compared with the blank control group, DAC and its combination with TSA and VPA significantly induced the expression of FMR1NB mRNA and protein in Cal27 and SCC-9 cells.Compared with DAC alone group, FMR1NB mRNA expression of each DAC-combined drug groups significantly increased, but FMR1NB protein did not significantly change in Cal27 cells; for SCC-9 cells, except for DAC+TSA group, the mRNA and protein levels of FMR1NB significantly increased in all other groups.In addition, there was no signifi-cant difference in the expression of FMR1 NB mRNA and protein between the three-combined drugs group and two-combined drugs groups.Further methylation assay showed that the methylation level of the overall FMR1NB promot-er and its each CpG site measured were reduced to varying degrees in all treatment groups except for three-combina-tion drug group of SCC-9.Conclusion DAC and its combination with TSA and VPA can enhance the expression of FMR1NB by mediating the demethylation of FMR1NB promoter, wherein the enhanced expression effect of the com-bination of the two drugs is stronger, suggesting that they have the potential to weaken the heterogeneity of FMR1NB expression and improve the immunotherapy effect of oral cancer.

Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

Objective: This study examined the gut bacterial communities of dogs from different breeds, all kept under identical domestication conditions. Methods: Noninvasive sampling and 16S rRNA high-throughput sequencing were used to compare the composition and function of the gut microbiota of three dog breeds: the Chinese Kunming dog (CKD), German Shepherd dog (GSD), and Belgian Malinois dog (BMD). Results: The gut microbiota of the three dog breeds consisted of 257 species across 146 genera, 60 families, 35 orders, 15 classes, and 10 phyla. The dominant bacterial phyla across the three breeds were Firmicutes (57.44%), Fusobacteriota (28.86%), and Bacteroidota (7.63%), while the dominant bacterial genera across the three breeds were Peptostreptococcus (21.08%), Fusobacterium (18.50%), Lactobacillus (12.37%), and Cetobacter (10.29%). Further analysis revealed significant differences in the intestinal flora of the three breeds at the phylum and genus levels. The intestinal flora of BMD was significantly richer than that of CKD and GSD. The functional prediction and Kyoto Encyclopedia of Genes and Genomes analysis showed that the primary functions of the gut microbiota in these breeds were similar, with significant enrichment in various metabolic pathways, including carbohydrate and amino acid metabolism, secondary metabolite biosynthesis, and microbial metabolism in different environments. The intestinal flora of these breeds also played a crucial role in genetic information processing, including transcription, translation, replication, and material transport. Conclusions and Relevance: These results provide novel insights into the intestinal flora of intervention dogs and suggest novel methods to improve their health status, which help increase microbial diversity and normalize metabolite production in diseased dogs.

Results : Database analysis showed that compared with other tumor types，LINC01152 was highly expressed in glioblastoma (GBM) and low grade glioma (LGG) ，and was higher than normal brain tissue．qRT-PCR showed that the expression of LINC01152 mRNA in glioma tissues was significantly higher than that in normal brain tissues (P＜0. 01)．The expression of LINC01152 was correlated with Ki-67 (P < 0. 05) ，but not with clinical parameters such as gender，age，tumor size，P53 protein，glial fibrillary acidic protein (GFAP) ，O-6-methylguanine-DNAmethyltransferase ( MGMT) and WHO grade of glioma patients． Functional enrichment analysis of co-expressed genes indicated that the LINC01152 was mainly involved in biological processes such as cell adhesion and synaptic signaling．LINC01152-miRNA-mRNA regulatory network was constructed according to predicted target genes．After down-regulation of LINC01152 expression，the proliferation，migration and invasion abilities of A172 and U87 cells decreased(P＜0. 01) ，while the apoptosis of glioma cells significantly increased (P＜0. 001) ． Conclusion LINC01152 is highly expressed in glioma，which can promote the malignant biological behavior of glioma cells by enhancing proliferation，migration as well as invasion and inhibition of apoptosis.

Objective:To observe any effect of repeated magnetic stimulation of the spine on lower urinary tract function and the life quality of patients with neurogenic bladder after suprasacral spinal cord injury (SCI).Methods:Fifteen suprasacral SCI patients whose lower urinary tract function was not improving were enrolled. In the first 2 weeks, all received water drinking management and intermittent catheterization, while in the following 4 weeks they were additionally provided with daily transspinal magnetic stimulation at the level of the spinous process of the first lumbar vertebra five times a week. The stimulation frequency was 1Hz. The patients kept voiding diaries. Their urodynamics were quantified using neurogenic bladder symptom scoring (NBSS) and a life quality scale.Results:The frequency of catheterization and the average voided volume, as well as the maximum detrusor pressure during the storage phase, maximum bladder capacity, maximum urethral pressure during the voiding phase and voiding efficiency at the end of the sixth week were significantly different from those at the end of the second week and before the intervention. The average NBSS and life quality scores then showed significant differences from the earlier time points.Conclusion:Repeteitive transspinal magnetic stimulation of the spine can improve lower urinary tract functioning and the life quality of persons with neurogenic bladder after a suprasacral SCI.

Objective:To investigate the association between oxygen saturation (SpO 2) and risk of 3-year all-cause mortality among Chinese older adults aged 65 or over. Methods:The participants were enrolled from Healthy Aging and Biomarkers Cohort Study in year of 2012 to 2014 in 9 longevity areas in China. In this prospective cohort study, 2 287 participants aged 65 or over were enrolled. Data on SpO 2 and body measurements were collected at baseline in 2012, and data on survival outcome and time of mortality were collected at the follow-up in 2014. Participants were divided into two groups according to whether SpO 2 was abnormal (SpO 2<94% was defined as abnormal). Results:The 2 287 participants were (86.5±12.2) years old, 1 006 were males (44.0%), and 315 (13.8%) were abnormal in SpO 2. During follow-up in 2014, 452 were died, 1 434 were survived, and 401 were lost to follow-up. The all-cause mortality rate was 19.8%, and the follow-up rate was 82.5%. The mortality rate of SpO 2 in normal group was 21.1%, and that of abnormal group was 41.6% ( P<0.001). After adjusting for confounding factors, compared to participants with normal SpO 2, participants with abnormal SpO 2 had increased risk of all-cause mortality with HR (95% CI) of 1.62 (1.31-2.02); HR (95 % CI) was 1.49 (0.98-2.26) for males and 1.71 (1.30-2.26) for females in abnormal SpO 2group, respectively; HR (95% CI) was 2.70 (0.98-7.44) for aged 65-79 years old, 1.22 (0.63-2.38) for aged 80-89 years old, and 1.72 (1.35-2.19) for aged over 90 years old in abnormal SpO 2 group, respectively. Conclusion:Abnormal SpO 2 was responsible for increased risk of 3-year all-cause mortality among Chinese elderly adults.
