Objective:To investigate the infection rate of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in patients with severe aplastic anemia (SAA) after intensive immunosuppressive therapy in combination with a thrombopoietin receptor agonist (lST+TPO-RA) as well as assess the clinical impact of treatment.Methods:A retrospective, case series study was undertaken involving patients with SAA who were admitted to Soochow Hopes Hematonosis Hospital, The First Affiliated Hospital of Soochow University, and Zhengzhou Third People′s Hospital from June 2022 to February 2025. Thirty patients with complete CMV and EBV monitoring data after IST+TPO-RA treatment were enrolled. The first activation time of CMV and EBV, the maximum viral load, the first negative conversion time, and blood routine tests within 3 days before CMV and EBV positivity, during the positive period, and within 3 days after turning negative were recorded. The patients were followed up for 9 months after the completion of IST. One-way analysis of variance was used to compare the changes of blood routine before and after virus positivity and after turning negative. The χ2 test was used to compare the viral infection rate and the therapeutic effect of IST between the two groups. Results:The 30 SAA patients comprised 15 males and 15 females with an average age of (40.0±16.9) years. Of the 30 patients, 18 (60.0%) were infected with CMV and 6 (20.0%) with EBV. Among them, 17 cases received rabbit anti-human thymocyte immunoglobulin (r-ATG) treatment (r-ATG group), 13 cases received porcine anti-human lymphocyte immunoglobulin (p-ALG) treatment (p-ALG group). The CMV infection rate was significantly higher in the r-ATG group than in the p-ALG group (15/17 vs. 3/13, χ2=13.03, P<0.001); meanwhile, the rate of EBV infection was only slightly higher in the r-ATG group than in the p-ALG group, and the difference did not reach statistical significance (5/17 vs. 1/13, χ2=2.17, P=0.196). In patients infected with CMV, neutrophil, hemoglobin, and platelet counts were significantly decreased during the infection phase, followed by significant increases after CMV clearance ( F=14.48, 11.38, 4.73; all P<0.05). No significant differences in treatment efficacy were found between the r-ATG and p-ALG groups at 3, 6, and 9 months post-IST (all P>0.05). Conclusions:This preliminary study showed that the incidence of CMV and EBV infection in patients with SAA increased after IST, with CMV infections occurring significantly more frequently than EBV infections. The CMV infection rate was significantly higher in patients treated with r-ATG than in those receiving p-ALG. CMV infection was associated with notable alterations in hematological parameters, highlighting the need for close clinical monitoring.

Objective:To explore the impact of the Yiqi Huoxue formula combined with nucleos(t)ide analogs (NAs) antiviral therapy on the serum N-glycan abundance in patients with hepatitis B-related liver fibrosis so as to clarify the application value of the oligosaccharide chain test (GT) for dynamic monitoring of the liver fibrosis progression.Methods:Sixty-two cases diagnosed with chronic hepatitis B at the Department of Hepatology, the Third Hospital of Hebei Medical University, between January 2020 and December 2022 were enrolled and divided into a Yiqi Huoxue Formula (YQHX) combined with NAs group and an NAs monotherapy group ( n=31), with 31 cases in each group for a total of 96 weeks of follow-up. Patient's basic clinical characteristics and liver stiffness measurement (LSM) were collected. GT was used simultaneously to detect the serum N-glycan profile and abundance changes. The nonparametric Mann-Whitney U test was used to compare the differences between the two groups. Enumeration data were expressed as number of cases and percentages (%). The χ2 test was used to compare constituent ratios between two or more groups. Correlation analysis was performed using the Spearman method, with P<0.05 considered statistically significant. Results:The proportion of patients was significantly higher in the YQHX combined with NAs group than the NAs monotherapy group [61.29% (19/31) vs. 9.68% (3/31), P<0.05] with no progression in liver fibrosis staging following 96 weeks of follow-up. The abundance of the N-glycan marker peak 8 [triantennary N-glycan (NA3)] had resulted in significant change for liver fibrosis improvements ( P<0.05), which predicts liver fibrosis progression and reversal in populations sensitive to traditional Chinese medicine. Conclusion:The combined application of Yiqi Huoxue formula and NAs can significantly promote the improvement rate of hepatitis B-related liver fibrosis. Serum N-glycan peak 8 may serve as a potential biomarker for monitoring the reversal of hepatitis B-related liver fibrosis.

Objective To explore the change of nucleoplasm distribution of glucocorticoid receptor alpha(GRα)in peripheral blood of children with primary nephrotic syndrome(PNS)during the course of the disease,aiming at evaluating the correlation between nuclear transport abnormality and different GC responses.Methods A total of 45 children with PNS were enrolled as subjects in this prospective study,and divided into steroid-sensitive nephrotic syndrome(SSNS,n=36)and steroid-resistant nephrotic syndrome(SRNS,n=9)groups,according to their response to GC.The SSNS group was further subclassified into non-frequently relapsing nephrotic syndrome(NFRNS,n=21)and frequently relapsing nephrotic syndrome(FRNS,n=15)based on relapse frequency during 12-month follow-up.Peripheral blood samples were collected before GC treatment,6-week and 6-month after GC treatment.GRα nuclear localization was detected by immunofluorescence assay,and their correlations with clinical-laboratory indicators were analyzed.Results Before the GC treatment,the average fluorescence intensity showed no significantly difference among different groups(P＞0.05),the GRαin the three groups were localized mainly in cytoplasm,and the nucleocytoplasmic ratio showed no significantly difference among the three groups(P＞0.05).6-week after the GC treatment,the average fluorescence intensity showed no significantly difference among the three groups(P＞0.05),the GRα in SSNS group were localized mainly in nucleus,while those in SRNS group were localized mainly in cytoplasm.Furthermore,nucleocytoplasmic ratio in NFRNS group and SRNS group demonstrated significant differences,while those in NFRNS group and FRNS group showed no significant difference(P＞0.05).6-month after the GC treatment,the average fluorescence intensity in NFRNS group and FRNS group showed no significant difference(P＞0.05),GRα in the two groups were localized mainly in nucleus,and their nucleocytoplasmic ratio had significantly differences(P＜0.05).The GRα nucleocytoplasmic ratio in children with PNS was negatively correlated with 24-hour urine protein(24 h-UTP),TNF-α,while positively correlated with serum albumin(Alb).Conclusion There are differences in nuclear transport ability among PNS children of SRNS,NFRNS and FRNS groups,and these differences are correlated with the differency of GC responses.
