Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective:To investigate the role of microRNA-709(miR-709)in erythroid development and its correlation with multiple hematological diseases.Methods:The expression of miR-709 in multiple tissues of mice was detected by qRT-PCR;The expression of miR-709 and other miRNAs in day-14.5 fetal liver cells from mouse embryos was detected by transcriptome microarray analysis;The expression of miR-709 in nucleated red blood cells derived from bone marrow and spleen,and in peripheral blood erythrocytes of mice was detected by magnetic bead sorting combined with qRT-PCR;The expression of miR-709 during erythroid differentiation of murine erythroleukemia(MEL)cells was analyzed by cell culture and qRT-PCR;The expression of miR-709 during erythroid lineage differentiation of mouse erythroid precursor cells derived from fetal livers was analyzed by magnetic bead sorting,flow cytometry,cell culture and qRT-PCR;The expression of miR-709 in peripheral blood of patients with different hematological diseases was measured by qRT-PCR.Results:Among the various tissues examined in mice,miR-709 exhibited the highest expression in peripheral blood,followed by high expression levels in muscle,bone marrow,and liver;In day-14.5 fetal liver cells from mouse embryos,miR-709 was highly expressed,significantly surpassing miR-451,which was most highly expressed in mature red blood cells;In nucleated red blood cells derived from mouse bone marrow and spleen,the expression of miR-709 was higher than that of miR-451,whereas the opposite pattern was observed in peripheral blood;During the differentiation of erythroid precursor cells derived from mouse embryonic liver,the expression level of miR-709 first increased and then decreased;During the differentiation of MEL cells,the expression of miR-709 gradually increased;Compared with the healthy controls,patients with myelodysplastic syndrome(MDS),α-thalassemia and β-thalassemia expressed lower levels of miR-709 in peripheral blood;while the expression of miR-709 in patients with infectious hemolytic anemia(IHA)was higher than that in healthy controls.Conclusion:miR-709 is highly expressed in the early stage of erythropoiesis and exhibits dynamic changes during erythroid development,potentially playing an important role.It is also differentially expressed in different hematological diseases,which is expected to serve as a promising biomarker and therapeutic target in the clinical diagnosis and treatment of hematological diseases.

Objective To investigate the value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI radiomics and signal intensity in hepatobiliary phase(HBP)in predicting the pathological differentiation degree of hep-atocellular carcinoma(HCC).Methods The clinical and imaging data of 224 patients pathologically confirmed with HCC were col-lected.All patients were randomly divided into test group(68 cases)and training group(156 cases)at a ratio of 7︰3.The ITK-SNAP software was used to delineate region of interest(ROI)on arterial phase(AP),portal venous phase(PVP)and HBP,the radiomics features of the tumor tissues were extracted and the radiomics models were established using the FAE software.Logistic regression analysis was used to determine the clinical independent predictors associated with the pathological differentiation degree of HCC and to construct clinical model and clinical-radiomics model.Receiver operating characteristic(ROC)curve was plotted for each model and the area under the curve(AUC)was calculated to compare the diagnostic efficacy of the models.Results Age,alpha-fetoprotein(AFP),and r-glutamyltransferase(r-GT)were independent risk factors for predicting the degree of pathological differentiation of HCC.The AUC of the clinical-radiomics model in the training group and test group were 0.825 and 0.779,respectively,which were higher than those of the radiomics model(0.812 and 0.771)and the clinical model(0.687 and 0.666).Conclusion Gd-EOB-DTPA enhanced MRI radiomics have certain value in predicting the degree of pathological differentiation of HCC,while the predictive value of the signal intensity on HBP and the signal intensity ratio(SIR)on HBP is limited.

Objective:To investigate the short-term efficacy and safety of rituximab (RTX) in children with calcineurin inhibitor (CNI) resistant steroid resistant nephrotic syndrome (SRNS).Methods:A retrospective case analysis was conducted. Thirteen children with CNI resistant SRNS who were regularly treated with RTX (375 mg/m 2 per dose (maximum dose 500 mg), 1 dose per week, a total of 4 doses) in Department of Nephrology, Children′s Hospital of Fudan University from January 2016 to December 2023 were enrolled. The general data, disease related information, urinary protein/creatinine, serum albumin, blood creatinine before RTX treatment, immunosuppressants, adverse events, and monthly urinary protein/creatinine, serum albumin, and blood creatinine indexes within 6 months after RTX treatment were collected. The changes of urinary protein/creatinine, serum albumin and estimated glomerular filtration rate (eGFR) before and after RTX at 3 and 6 months were analyzed by using paired sample t test and Wilcoxon signed-rank test. Results:Among the 13 patients, 8 were male and 5 were female. The age of disease onset was 4.0 (2.9, 6.8) years and the age of RTX treatment was 9.8 (5.9, 13.6) years. There were 8 cases of focal segmental glomerulosclerosis, 3 cases of minimal change disease and 2 cases of mesangial proliferative glomerulonephritis. No clinically significant gene variation was detected in 12 cases and the other one did not receive gene test. Before RTX treatment, 11 cases were in chronic kidney disease stage G1, and 1 case each was in stage G2 and stage G3. Ten children completed 4 doses of RTX treatment, 1 patient completed 3 doses, and 2 patients completed 2 doses. Urinary protein/creatinine in 13 children at 3 and 6 months after RTX treatment was significantly lower than baseline (0.60 (0.13, 2.04), 0.49 (0.28, 1.10) vs. 1.44 (0.76, 4.11) mg/mg, Z=-2.34, -2.34, both P<0.05), and serum albumin was significantly higher than baseline ((35±8), (34±7) vs. (30±6) g/L, t=2.30, 2.60, both P<0.05). The eGFR at 6 months after RTX treatment was not significantly different from the baseline ((110±32) vs. (113±35) ml/(min·1.73 m 2), t=-0.76, P>0.05)). No serious adverse reactions occurred in this study. Conclusion:RTX could reduce urinary protein and increase serum albumin in short-term treatment in children with CNI resistant SRNS without significant side effects.

Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

OBJECTIVE: To analyze the Epstein-Barr virus (EBV) load in different lymphocyte subsets, as well as clinical characteristics and outcomes in patients with hematologic malignancies experiencing EBV reactivation. METHODS: Peripheral blood samples from patients were collected. B, T, and NK cells were isolated sorting with magnetic beads by flow cytometry. The EBV load in each subset was quantitated by real-time quantitative polymerase chain reaction (RT-qPCR). Clinical data were colleted from electronic medical records. Survival status was followed up through outpatient visits and telephone calls. Statistical analyses were performed using SPSS 25.0. RESULTS: A total of 39 patients with hematologic malignancies were included, among whom 35 patients had undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT). The median time to EBV reactivation was 4.8 months (range: 1.7-57.1 months) after allo-HSCT. EBV was detected in B, T, and NK cells in 20 patients, in B and T cells in 11 patients, and only in B cells in 4 patients. In the 35 patients, the median EBV load in B cells was 2.19×10⁴ copies/ml, significantly higher than that in T cells (4.00×10³ copies/ml, P <0.01) and NK cells (2.85×10² copies/ml, P <0.01). Rituximab (RTX) was administered for 32 patients, resulting in EBV negativity in 32 patients with a median time of 8 days (range: 2-39 days). Post-treatment analysis of 13 patients showed EBV were all negative in B, T, and NK cells. In the four non-transplant patients, the median time to EBV reactivation was 35 days (range: 1-328 days) after diagnosis of the primary disease. EBV was detected in one or two subsets of B, T, or NK cells, but not simultaneously in all three subsets. These patients received a combination chemotherapy targeting at the primary disease, with 3 patients achieving EBV negativity, and the median time to be negative was 40 days (range: 13-75 days). CONCLUSION In hematologic malignancy patients after allo-HSCT, EBV reactivation commonly involves B, T, and NK cells, with a significantly higher viral load in B cells compared to T and NK cells. Rituximab is effective for EBV clearance. In non-transplant patients, EBV reactivation is restricted to one or two lymphocyte subsets, and clearance is slower, highlighting the need for prompt anti-tumor therapy.
