Background/Aims: This study assessed the long-term efficacy and safety of tenofovir alafenamide (TAF) in real-world settings. Methods: Patients who were candidates for TAF treatment and were followed up at 12-week intervals over 192 weeks were enrolled in this study. Results: One hundred and forty-four patients (50 treatment-naive and 94 treatment-experienced) were included in this study. The cumulative incidence rates of cirrhosis and hepatocellular carcinoma at 192 weeks were 3.9% and 0.7%, respectively. In treatment-naive patients, the rates of a virological response, HBeAg conversion, and HBsAg loss at 192 weeks were 100%, 33.3%, and 2%, respectively. The treatment-naive patients exhibited higher baseline HBsAg levels than the treatment-experienced patients (4.31 log10IU/mL vs. 3.97 log10IU/mL). A significant decrease in the HBsAg levels from the baseline was observed at 144 and 192 weeks in the treatment-naive patients (p=0.01). The baseline body mass index (BMI) <25 kg/m2 (p=0.02) and HBsAg <3.3 log10IU/mL (p=0.04) were identified as predictive factors for a decrease in HBsAg ≥0.5 log10IU/mL at 48 weeks. The eGFR levels were consistently lower in the treatment-experienced patients throughout the study. Although the treatment-naive patients showed no abnormal increases in urinary URBP, the treatment-experienced patients showed elevated urinary β2MG and NAG levels at the baseline, which decreased over the treatment course. The total cholesterol, triglyceride, and low-density lipoprotein levels were similar in both groups. Conclusions Prolonging the TAF treatment duration enhances the virological response rate. The decline in HBsAg levels was more significant in the treatment-naive patients than in the treatment-experienced patients. The baseline BMI <25 kg/m2 and HBsAg <3.3 log10IU/mL were predictive factors for a significant decline in HBsAg at 48 weeks. TAF has high renal safety and no significant impact on lipid levels.

Objective To establish age estimation models of northern Chinese Han adults using cranial suture images obtained by CT and multiplanar reformation(MPR),and to explore the applicability of cranial suture closure rule in age estimation of northern Chinese Han population.Methods The head CT samples of 132 northern Chinese Han adults aged 29-80 years were retrospectively collected.Volume reconstruction(VR)and MPR were performed on the skull,and 160 cranial suture tomography images were generated for each sample.Then the MPR images of cranial sutures were scored according to the closure grading criteria,and the mean closure grades of sagittal suture,coronal sutures(both left and right)and lambdoid sutures(both left and right)were calculated respectively.Finally taking the above grades as independent variables,the linear regression model and four machine learning models for age estimation(gradient boosting regression,support vector regression,decision tree regression and Bayesian ridge regression)were established for northern Chinese Han adults age estimation.The accu-racy of each model was evaluated.Results Each cranial suture closure grade was positively correlated with age and the correlation of sagittal suture was the highest.All four machine learning models had higher age estimation accuracy than linear regression model.The support vector regression model had the highest accuracy among the machine learning models with a mean absolute error of 9.542 years.Conclusion The combination of skull CT-MPR and machine learning model can be used for age esti-mation in northern Chinese Han adults,but it is still necessary to combine with other adult age estima-tion indicators in forensic practice.

This study was aimed at understanding the genomic characteristics of the Vibrio cholerae O1 group isolated from humans in Fujian Province,to provide essential data for the molecular epidemiological study of cholera.From 2008 to 2022,16 strains of the V.cholerae O1 group from patients and carriers were collected,and antibiotic sensitivity was determined accord-ing to the minimum inhibitory concentration(MIC).The whole genome sequences obtained through second generation sequen-cing were analyzed in open source software,including snippy,Roary,and Prokka,as well as online analysis websites,inclu-ding NCBI and BacWGSTdb,for core-genome multilocus sequence typing(cgMLST),core-genome single nucleotide polymor-phism analysis(cgSNP),virulence gene analysis,drug resistance gene prediction,and pan-genomic diversity analysis.The whole genome sequences of V.cholerae were divided into five sequence types(STs),among which the newly discovered ST182 and ST1480 were the evolutionary branches of the current dominant clonal group ST75 in China,and were highly related to two strains isolated from Taiwan in 2010 and 2013,respectively.Both toxigenic strains and non-toxigenic strains carried a variety of virulence factors and showed gene variation to varying degrees.Thirteen drug resistance genes in seven categories were predicted,among which the distribution of colistin and tetracycline resistance genes was consistent with the drug resistance phenotype.Pan-ge-nomic analysis indicated that V.cholerae had an open pan-genome,and Roary cluster analysis showed higher resolution than cgMLST.In summary,V.cholerae O1 group isolates from humans in Fujian Province have polymorphisms in genome structure and function,and the newly discovered ST1480 clone group has epidemic potential.Therefore,the monitoring of such strains must be strengthened.

Objective:To explore the neuroprotective effects and mechanisms of memantine on sepsis-associated encephalopathy (SAE) model mice.Methods:Totally 90 male C57BL/6J mice aged 8-12 weeks were randomly divided into 3 groups (with 30 mice in each group) : sham group, model group and memantine group. The SAE mouse model was established by cecum ligation and puncture while mouse in sham group received open and closed abdomen only. The mice in the memantine group were irrigation with memantine (15 mg · kg -1· d -1) 3 hours before surgery and 7 consecutive days after modeling. The mice in the model group and sham group were irrigation with an equal volume of 0.9% sodium chloride solution. The 7-day survival rate was observed, neurobehavioral and cognitive function scores of each group of mice after modeling were assessed.Blood-brain barrier permeability was measured by detecting the content of Evans blue. Immunofluorescence staining was used to detect the expression of astrocytes. Enzyme linked immunosorbent assay was conducted to detect cellular inflammatory factors and the glutamic acid content detection kit was used to detect the expression of glutamic acid. All data were analyzed by Graphpad Prism 8.3.0 software, survival rate was analyzed using Kaplan-Meier survival curve.Multigroup comparisons were conducted by one-way ANOVA or Kruskal-Wallis test. Results:(1) There was a statistically significant difference in the 7-day survival rate among the three groups of mice after modeling ( F=24.11, P<0.01), and the 7-day survival rate of the memantine group was higher than that of the model group (57% (17/30), 27% (8/30), P<0.01). (2)The behavioral results showed that after 7 days of modeling, there were statistically significant differences in the total distance of the open field test, central area stay time, four corner area stay time, neurobehavioral scores, pole climbing test, and preference index for new object recognition test among the three groups of mice ( F/ χ2=17.67, 17.30, 9.39, 14.06, 10.36, 14.81, all P<0.05).The neurobehavioral score, pole climbing test score, preference index for new object recognition test, total distance of open field test, and central area stay time of the model group were all lower than those of the sham group (all P<0.05), while four corner area stay time of the model group was higher than that of the sham group ( P<0.05).The total distance of open field test (1 564.07(1 363.24, 1 988.19) cm, 913.91 (574.32, 1 096.23) cm), central area stay time (5.21 (4.91, 8.76) s, 1.09 (0.25, 1.64) s), neurobehavioral scores (9.75±0.50, 8.25±0.50), pole climbing test scores (5.67±0.52, 4.56±0.53), and preference index for new object recognition test (56.50±10.59, 26.84±2.91) of the memantine group were all higher than those of the model group (all P<0.05). The four corner area stay time was lower than that of the model group ((480.30±50.64) s, (529.80±36.20) s, P<0.05).(3)The comparison of molecular indicators showed that there were statistically significant differences in the content of Evans blue in the brain, the number of astrocytes in the hippocampus and cerebral cortex, pro-inflammatory cytokines (TNF-α、IL-1β、IL-6), anti-inflammatory cytokines (IL-10), and glutamic acid among the three groups of mice ( F/ χ2=8.84, 6.43, 28.46, 23.63, 12.23, 16.04, 69.22, 6.65, all P<0.05).The content of Evans blue, the number of astrocytes in the hippocampus and cerebral cortex, the expression of TNF-α、IL-1β、IL-6, and glutamate in the model group were all lower than those in the sham group(all P<0.05). The levels of IL-10 in the model group was lower than that in the sham group ( P<0.05).The content of Evans blue ((5.67±1.38)μg/g, (11.08±2.79)μg/g), the number of astrocytes in the hippocampus (16.50 (13.75, 22.25)/μm 2), 80.00 (73.50, 83.50)/μm 2) and the cerebral cortex (40.00 (29.00, 48.00)/μm 2, 81.50 (72.25, 89.00)/μm 2) in the memantine group were lower than those in the model group (all P<0.05).The pro-inflammatory factor TNF-α, IL-1β, IL-6 and glutamic acid expression in the memantine group were lower than those in the model group (all P<0.05), and the anti-inflammatory cytokine IL-10 was higher than that in the model group ( P<0.05). Conclusions:Memantine can improve the neurobehaviors and cognitive functions of SAE mice through improving the integrity of the damaged blood-brain barrier, alleviating inflammation in the brain, as well as reducing glutamate levels in the brain.

Aim To investigate the protective effect of eriodictyol(ERD)on kidney damage in hypertensive mice and its possible mechanism.Methods Thirty C57BL/6J mice were randomly divided into five groups of six in each group.They were the control group(Ctrl),the hypertension model group(DOCA/Salt),the eriodictyol low-dose(DOCA/Salt+ERD-L),the high-dose(DOCA/Salt+ERD-H)and the positive drug perindopril group(DOCA/Salt+Perindopril).The classic hypertension model was induced by DOCA/Salt,and ERD was administered continuously for four weeks,and blood pressure,serum urea nitrogen,cre-atinine and other indicators were measured.Hematoxy-lin-eosin staining(HE)and Masson staining were used to observe the pathological changes of the kidney.Western blot was used to detect the expression of EMT marker proteins α-SMA,Vimentin,E-cadherin and FN in renal epithelial mesenchymal transition.Real-Time PCR was used to detect the expression of renal inflammatory cytokines Nlrp3,TNF-α,IL-1 β,IL-18,MCP-1 and NADPH oxidase(NOXs).Western blot was employed to detect the expression levels of TGF-β1,phosphorylated(p)-Smad2,TLR4 and NF-κB p65 proteins in mice.Results ERD intervention could delay the occurrence of hypertension,improve the pathological damage of renal tissue,reduce renal collagen deposition.It could also reduce the level of renal inflammation and oxidative stress,improve the level of EMT protein,and significantly reduce the pro-tein expression of TGF-β1,p-Smad2,TLR4 and NF-κB p65.Conclusions ERD is shown to have a signif-icant protective effect on DOCA/Salt hypertensive renal damage,and its mechanism may be related to the regu-lation of TGF-β1/Smad2,TLR4/NF-κB p65 and other signaling pathways.
