[Objective] To explore the accuracy and feasibility of non-invasive prenatal diagnosis of fetal RhE genotype using cell-free fetal DNA (cff-DNA) from maternal peripheral blood. [Methods] A total of 134 pregnant women with single fetuses and RhE-negative blood group were selected from our hospital from November 2023 to August 2024. Free DNA extraction kit was used to extract free DNA from peripheral blood of pregnant women, and the RhE blood group genotype of free DNA was detected by real-time fluorescent quantitative PCR (RT-qPCR). If the qPCR amplification signal of the sample was negative, the methylated RASSF1A gene was amplified, and the positive amplification result was used as a sign of successful extraction of cff-DNA. Serological microcolumn gel method was used to detect the phenotype of RhE blood group in neonatal peripheral blood. [Results] Among the 134 maternal peripheral blood samples, the cff-DNA detection of RhE blood group phenotypes was consistent with the RhE blood group genotyping of neonatal peripheral blood in 133 cases, including 90 cases of Rhee genotype and 43 cases of RhE genotype, with diagnostic concordance rate of 99.3%, sensitivity of 97.7%, specificity of 100%, youden index of 0.977, area under ROC curve of 0.995, the Kappa value of 0.983, positive predictive value of 100%, and negative predictive value of 98.9%. The sample of 1 case failed to be detected. After the amplification of methylated RASSFIA gene, it was confirmed that the reason for the failure was that no cff-DNA was extracted from the sample. The diagnostic concordance rates of the first, second and third trimesters were 93.8% (15/16), 100% (51/51) and 100% (67/67), respectively. Fisher's exact test method was used to calculate the P value, which was P>0.05, indicating that there was no statistical significance in the difference of diagnostic concordance rate among the three pregnancy periods, and there was no difference in the detection concordance rate of this method in different pregnancy periods. [Conclusion] The use of cff-DNA in maternal peripheral blood for the detection of fetal RhE blood group genotype is an accurate and highly feasible non-invasive prenatal diagnostic method, which is helpful for the clinical diagnosis of fetal and neonatal hemolytic disease caused by anti-E antibody.

Objective:To investigate the protective effect of quercetin against LasB-induced apoptosis, inflammation, and oxidative stress in THP-1 macrophages, providing valuable insights into the use of quercetin as a virulence inhibitor for Pseudomonas aeruginosa infection treatment. Methods:This was an experimental study. The experimental strain was the standard strain. The LasB protein was obtained utilizing protein recombination technology, while the enzyme activity of LasB was assessed through both the Elastin Congo red assay and fluorescently labelled elastin assay. The LasB-induced THP-1 macrophage infection model was established, and quercetin was utilized for intervention. Cell viability was evaluated via CCK-8 assay, while cell morphology was observed under an inverted microscope. Apoptosis detection involved employing both TUNEL and Annexin V/PI staining. The mRNA expression and protein levels of inflammatory cytokines and COX-2 were determined by RT-qPCR and ELISA respectively. Intracellular ROS levels were quantified using the DCFH-DA fluorescent probe. One-way ANOVA was used for statistical analysis, and Tukey test was used for multiple comparisons. Results:The pLasB with a molecular weight of 33 000 and acceptable enzymatic activity (purity>90%), was successfully obtained. THP-1 macrophages treated with pLasB at a concentration of 100 μg/ml presented significantly decreased viability and integrity rate when compared with the normal control group. Additionally, pLasB promoted apoptosis, up-regulated the levels of inflammatory cytokines IL-1α, IL-1β, IL-6, IL-10, IL-12, and TNF-α, increased intracellular ROS fluorescence intensity, and elevated COX-2 mRNA expression level. Furthermore, the viability of THP-1 macrophages was significantly enhanced under quercetin intervention at concentrations of 2.5 μmol/L, 5 μmol/L and 10 μmol/L. The apoptosis rate exhibited a significant reduction from 18.32%±0.17% to 13.17%±0.20%, 11.43%±0.06% and 7.74%±0.04%, respectively ( F=1 679, P<0.05). There was a notable down-regulation of pro-inflammatory cytokines IL-1α, IL-1β, IL-6, IL-12 and TNF-α while the anti-inflammatory cytokine IL-10 showed a significant up-regulation. Both intracellular ROS fluorescence intensity ( F=86.92, P<0.05) and COX-2 level ( F=24.62, P<0.05) demonstrated a substantial decrease. Conclusion:Quercetin demonstrates significant efficacy in inhibiting LasB-induced apoptosis, inflammation, and oxidative stress in THP-1 macrophages, which highlights immense potential as a potent virulence inhibitor of Pseudomonas aeruginosa.

In recent years,challenges persist in the grassroots Party building in the university-affiliated hospitals though increased efforts have been intensified.These challenges include a lack of alignment between Party building and the hospital's central tasks,an absence of distinctive Party building brands,an insufficiently prominent role of Party organizations in hospital development,and inadequate leveraging of the Party construction for promoting medical services and cultivating medical talents.Starting from an exploration of the connotation and significance of constructing framework of"One Integration and Two Highs"in university-affiliated hospitals,this paper conducts an in-depth analysis of the existing problems and their causes within this frame-work.From a holistic perspective,the paper proposes a new path for establishing the"One Integration and Two Highs"frame-work in university-affiliated hospitals,centered around"Seven Integrations":concept integration,organization integration,strength integration,vehicle integration,culture integration,innovation integration,and assessment integration.

Background/Aims: Existing hepatocellular carcinoma (HCC) prediction models are derived mainly from pretreatment or early on-treatment parameters. We reassessed the dynamic changes in the performance of 17 HCC models in patients with chronic hepatitis B (CHB) during long-term antiviral therapy (AVT). Methods: Among 987 CHB patients administered long-term entecavir therapy, 660 patients had 8 years of follow-up data. Model scores were calculated using on-treatment values at 2.5, 3, 3.5, 4, 4.5, and 5 years of AVT to predict threeyear HCC occurrence. Model performance was assessed with the area under the receiver operating curve (AUROC). The original model cutoffs to distinguish different levels of HCC risk were evaluated by the log-rank test. Results: The AUROCs of the 17 HCC models varied from 0.51 to 0.78 when using on-treatment scores from years 2.5 to 5. Models with a cirrhosis variable showed numerically higher AUROCs (pooled at 0.65–0.73 for treated, untreated, or mixed treatment models) than models without (treated or mixed models: 0.61–0.68; untreated models: 0.51–0.59). Stratification into low, intermediate, and high-risk levels using the original cutoff values could no longer reflect the true HCC incidence using scores after 3.5 years of AVT for models without cirrhosis and after 4 years of AVT for models with cirrhosis. Conclusions The performance of existing HCC prediction models, especially models without the cirrhosis variable, decreased in CHB patients on long-term AVT. The optimization of existing models or the development of novel models for better HCC prediction during long-term AVT is warranted.

Portal hypertension is a serious complication of liver cirrhosis resulting from the increases in portal vascular resistance and portal blood inflow. Both etiological and non-etiological therapies can effectively reduce portal venous pressure to a certain degree, but with an unsatisfactory effect in improving prognosis. New therapeutic drugs targeting the reduction in intrahepatic vascular resistance may help to achieve the reversal of portal hypertension. Based on the pathogenesis of cirrhotic portal hypertension, this article summarizes the current pharmacotherapies from the aspects of etiological and non-etiological therapies, so as to provide a comprehensive theoretical and evidence-based basis for clinical treatment options.

Objective:Our study aims to determine histological regression and clinical improvement after long-term antiviral therapy in hepatitis B virus-related cirrhosis patients.Methods:Treatment-na?ve chronic hepatitis B patients with histologically or clinically diagnosed liver cirrhosis were enrolled. Liver biopsies were performed after 5 years entecavir-based antiviral treatment. Patients were followed up every 6 months. Cirrhosis regression was evaluated based on Metavir system and P-I-R score. Clinical improvement was evaluated before and after the long-term treatment. Kruskal Wallis test and Wilcoxon signed-rank test were used for continuous variables, Fisher's exact test was used for categorical variables and multivariate analysis was performed using logistic regression analysis.Results:Totals of 73 patients with HBV-related liver cirrhosis were enrolled. Among them, 30 (41.1%) patients were biopsy proved liver cirrhosis and the remaining 43 (58.9%) cirrhotic patients were diagnosed by clinical features. Based on Metavir system and P-I-R score, 72.6% (53/73) patients attained histological regression. Furthermore, 30.1% (22/73) were defined as significant regression (Metavir decrease ≥2 stage), 42.5% (31/73) were mild regression (Metavir decrease 1 stage or predominantly regressive by P-I-R system if still cirrhosis after treatment) and 27.4% (20/73) were the non-regression. Compared to levels of clinical characteristics at baseline, HBV DNA, ALT, AST, liver stiffness(decreased from 12.7 to 6.4 kPa in significant regression, from 18.1 to 7.3 kPa in mild regression and from 21.4 to 11.2 kPa in non-regression)and Ishak-HAI score significantly decreased after 5 years of anti-HBV treatment, while serum levels of platelets and albumin improved remarkably ( P<0.05). In multivariate analysis, only the pre-treatment liver stiffness level was associated with significant regression ( OR=0.887, 95% CI: 0.802-0.981, P=0.020). Conclusions:After long-term antiviral therapy, patients with HBV-related cirrhosis are easily to attain improvements in clinical parameters, while a certain percentage of these patients still cannot achieve histological reversal.

Objective:To clarify the effect and related factors of antiviral therapy on the change of esophageal varices in patients with hepatitis B virus-related cirrhosis.Methods:Fifty-two cases with hepatitis B virus-related cirrhosis who underwent endoscopy before and after antiviral therapy were selected from prospective cohorts. Patients were divided into three groups: no, mild, and moderate-severe based on the degree of esophageal varices. The changes in the severity of esophageal varices in each group were compared after antiviral therapy. Clinical characteristics (platelet, liver and kidney function, liver stiffness, and virological response) of patients with different regressions were analyzed. Measurement data were analyzed by independent sample t-test, one-way ANOVA, Mann-Whitney U test and Kruskal-Wallis H test, and Chi-Square test was used for count data.Results:All patients received entecavir-based antiviral therapy. The median treatment time was 3.1 (2.5-4.4) years. The proportion of patients without esophageal varices increased from 30.8% to 51.9%, the proportion of mild esophageal varices decreased from 40.4% to 30.8%, and the proportion of patients with moderate-to-severe esophageal varices decreased from 28.8% to 17.3% ( χ2=14.067, P=0.001). A total of 40.4% of patients had esophageal varices regression, and 13.5% had esophageal varices progression. The progression rate was significantly higher in patients with moderate-severe esophageal varices than patients with mild and no esophageal varices ( χ2=28.126, P<0.001), and 60.0% of patients with moderate-severe esophageal varices still remained in moderate-severe state after antiviral treatment. Baseline platelet count and 5-year mean change rates were significantly lower in patients with progressive moderate-to-severe esophageal varices than in those without progression (+3.3% vs. +34.1%, Z=7.00, P=0.027). Conclusion:After effective antiviral treatment, 40.4% of patients with hepatitis B virus-related cirrhosis combined with esophageal varices has obtained esophageal varices regression, but those with moderate to severe esophageal varices still have a considerable risk of progression while receiving mono antiviral treatment only. Thrombocytopenia and without significant improving are the clinical signs of progression risk after receiving antiviral treatment.
