ObjectiveTo investigate the clinical features of patients with acute-on-chronic liver failure (ACLF), and to construct a risk scoring table that can accurately predict the prognosis of patients in the early stage. MethodsA retrospective analysis was performed for the clinical data of 502 patients with ACLF who were admitted to Tangdu Hospital, Air Force Medical University, from January 1, 2010 to December 31, 2020 (training set), and the influencing factors for 28-day mortality rate were identified. The 69 ACLF patients who were admitted to Tangdu Hospital, Air Force Medical University, from January 1 to December 31, 2021 were enrolled as the validation set. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A univariate Cox regression analysis was used to obtain the early warning indicators associated with the 28-day prognosis of ACLF patients, and variance inflation factors were used to assess multicollinearity among predictors; a multivariate Cox regression analysis was used to construct a risk model for ACLF prognosis (mortality). A risk scoring table for ACLF prognosis (mortality) was developed based on regression coefficients (β) from the model equation and weight assignments in the nomogram. Internal validation and comparison were performed for the risk model for ACLF prognosis (mortality), the scoring table for ACLF prognosis (mortality), and other scoring models (Child-Turcotte-Pugh [CTP] score, Model for End-Stage Liver Disease [MELD] score, MELD combined with serum sodium concentration [MELD-Na] score, and integrated MELD [iMELD] score) in the training set, while external validation and comprehensive evaluation of the scoring table and the other scoring models were performed in the validation set. The Nagelkerke’s R2 test and the Hosmer-Lemeshow test were used to assess the degree of fitting of the risk model for ACLF prognosis (mortality), the scoring table for ACLF prognosis (mortality), and other scoring models, and fitting curves were plotted. C-index was used to assess the discriminatory ability of the scoring table for ACLF prognosis (mortality) and the other scoring models, and the Z-test was used for comparison of C-index between different models. The decision curve analysis was used to compare the clinical benefits of the scoring table for ACLF prognosis (mortality) and the other scoring models. ResultsThe multivariate Cox regression analysis showed that age (hazard ratio [HR]=1.027, 95% confidence interval [CI]: 1.015 — 1.039, P<0.001), hepatic encephalopathy grade (grade 1: HR=2.928, 95%CI: 1.463 — 5.858, P=0.002; grade 2: HR=3.811, 95%CI: 2.078 — 6.988, P<0.001; grade 3: HR=3.916, 95%CI: 1.917 — 8.001, P<0.001; grade 4: HR=6.966, 95%CI: 4.559 — 10.644, P<0.001), an increase in total bilirubin (TBil) by ≥17.1 μmol/L per day (HR=1.771, 95%CI: 1.248 — 2.513, P=0.001), creatinine (HR=1.005, 95%CI: 1.004 — 1.006, P<0.001), neutrophil count (HR=1.092, 95%CI: 1.060 — 1.126, P<0.001), and international normalized ratio (HR=1.298, 95%CI: 1.187 — 1.418, P<0.001) were independent risk factors associated with the 28-day mortality rate of ACLF patients, and a risk scoring table was constructed for ACLF prognosis (mortality). The Nagelkerke’s R2 test showed that the risk scoring table for ACLF prognosis (mortality) had an R2 value of 0.599 in the training set and 0.722 in the validation set, which were higher than the R2 values of CTP, MELD, MELD-Na, and iMELD scores. The Hosmer-Lemeshow test showed that the risk scoring table for ACLF prognosis (mortality) had a P value of 0.280 in the training set and 0.788 in the validation set. The C-index analysis showed that the scoring table had a higher C-index than the other scoring models in the validation set (all P<0.001), as well as a higher C-index than CTP score in the training set (P<0.001). The decision curve analysis showed that the risk scoring table for ACLF prognosis (mortality) had higher clinical net benefits than the other scoring models. ConclusionCompared with other scoring models currently used in clinical practice, the novel risk scoring table for ACLF prognosis (mortality) constructed based on the six predictive factors of age, hepatic encephalopathy grade, an increase in TBil by ≥17.1 μmol/L per day, creatinine, neutrophil count, and international normalized ratio has a relatively high value in predicting the 28-day prognosis of ACLF patients.

ObjectiveTo observe the efficacy of Huoxue Jiedu Formulas (活血解毒方药, HJF) as an adjunctive treatement for patients with binding of stasis and toxin syndrome during the vulnerable period after acute myocardial infarction (AMI) percutaneous coronary intervention (PCI) surgery, and to explore its potential mechanism from the perspective of serum neutrophil extracellular traps (NETs). MethodsA total of 129 patients with binding of stasis and toxin syndrome within 6 months after PCI for AMI were enrolled and divided into a treatment group (65 cases) and a control group (64 cases) based on patients' willingness to take Chinese herbal medicine. The control group received standard western medical therapy alone, while the treatment group additionally received HJF, one dose daily. Both groups were treated for four weeks. Before and after treatment, TCM syndrome scores were assessed. Seattle angina questionnaire (SAQ) was used to record angina stability and frequency scores, while the short form-36 health survey (SF-36) was employed to assess quality of life across eight dimensions, including physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. The Pittsburgh sleep quality index (PSQI) was used to evaluate sleep quality, and the patient health questionnaire-15 (PHQ-15) was used to assess psychosomatic symptoms; Duke activity status index (DASI) was used to measure daily physical activity. Serum levels of neutrophil extracellular traps (NET) markers including myeloperoxidase-DNA (MPO-DNA), neutrophil elastase-DNA (NE-DNA), and citrullinated histone H3 (CitH3) were measured in 20 patients from the treatment group. ResultsAfter treatment, TCM syndrome score, PSQI score and PHQ-15 score in both groups significantly decreased, while DASI score, angina stability and frequency scores, and all eight dimensions of the SF-36 scale significantly increased (P<0.05). Compared to the control group, the treatment group had significantly lower TCM syndrome scores and significantly higher DASI, angina stability and frequency scores (P<0.05), as well as higher scores in the SF-36 dimensions of physical functioning, role-physical, social functioning, bodily pain, and vitality (P<0.05). After treatment, serum levels of MPO-DNA, CitH3, and NE-DNA in the treatment group were significantly reduced (P<0.05). ConclusionHJF combined with conventional therapy can significantly improve angina symptoms, TCM syndrome scores, and psychosomatic conditions in patients with binding of stasis and toxin syndrome during the vulnerable period after AMI. It also enhances quality of life, sleep quality, and daily physical activity. The underlying mechanism may be associated with the inhibition of serum NETs level.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Methods:
The case data of brucellosis in Shanxi Province from 2019 to 2023 were collected through the Infectious Disease Surveillance System of the Chinese Disease Prevention and Control Information System. The seasonal distribution, population distribution, and region distribution of brucellosis cases were described. Spatial autocorrelation analysis was applied to explore the spatial clustering characteristics of brucellosis.
Results:
A total of 21 241 human brucellosis cases were reported in Shanxi Province from 2019 to 2023, with an average annual reported incidence of 11.87/100 000, showing an upward trend (P<0.05). The peak incidence period was from March to August, with 14 163 cases reported cumulatively, accounting for 66.68% of the total. There were 16 336 male cases and 4 905 female cases, with a male-to-female ratio of 3.33:1. The high-incidence age group was 40-<70 years, with 15 675 cases accounting for 73.80%. The majority of patients were farmers, with 17 926 cases accounting for 84.39%. Spatial autocorrelation analysis showed that there was spatial clustering in the incidence of brucellosis from 2019 to 2023 (all Moran's I>0, P<0.05). The high-high clustering areas were mainly Datong City, and Shuozhou City in northern Shanxi, and Linfen City in the southern Shanxi. The low-low clustering areas were mainly Taiyuan City and Yangquan City in central Shanxi, and Changzhi City and Jincheng City in southeastern Shanxi.
Conclusions

ObjectiveTo investigate the change in the activity of hepatitis B virus (HBV)-specific CD8+ T cells after pegylated interferon-α-2b (PEG-IFN-α-2b) therapy in HBeAg-negative patients with chronic HBV infection. MethodsA total of 53 HBeAg-negative patients with chronic HBV infection who attended The First Affiliated Hospital of Xinxiang Medical University and Tangdu Hospital of Air Force Mdical University from April 2020 to June 2022 were enrolled and treated with PEG-IFN-α-2b (180 μg/week, subcutaneous injection) antiviral therapy. The study endpoint was HBsAg clearance (course of treatment<48 weeks) or 48 weeks (course of treatment≥48 weeks). Peripheral blood mononuclear cells were isolated at baseline and study endpoint, and peripheral blood T cell counts were measured. Enzyme-linked immunospot assay was used to measure the frequency of HBV-specific CD8+ T cells secreting perforin, granzyme B, and interferon-γ. A total of 17 HLA-A*02-restricted patients were selected, and CD8+ T cells were purified to establish direct- and indirect-contact co-culture systems for HBV-specific CD8+ T cells and HepG2.2.15 cells. The level of lactate dehydrogenase in supernatant was measured to calculate the mortality rate of HepG2.2.15 cells, and the levels of HBV DNA, cytotoxic molecules, and cytokines in supernatant were also measured. Flow cytometry was used to measure the expression of apoptosis ligands, and the cytotoxicity of HBV-specific CD8+ T cells was evaluated. The independent samples t-test or the paired t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test or the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. ResultsThe HBsAg clearance rate at study endpoint was 30.19% (16/53). There were no significant differences in peripheral blood T cell counts (CD3+, CD4+, and CD8+ T cells) between baseline and study endpoint (P>0.05). At study endpoint, there was a significant increase in the frequency of HBV-specific CD8+ T cells secreting perforin, granzyme B, and interferon-γ (U=177.50, t=11.90, U=186.50, all P<0.001), and the patients with HBsAg clearance had a significantly higher frequency of such HBV-specific CD8+ T cells than those without HBsAg clearance (U=120.50, t=2.73, U=121.50, all P<0.01). In the direct- and indirect-contact co-culture systems at study endpoint, HBV-specific CD8+ T cells induced a significant reduction in HBV DNA in the supernatant of HepG2.2.15 cells (all P<0.001) and significant increases in the secretion of interferon-γ and tumor necrosis factor-α (all P<0.05); in the direct-contact co-culture system, HBV-specific CD8+ T cells induced significant increases in the mortality rate of HepG2.2.15 cells (13.62%±3.27% vs 11.39%±2.40%, t=2.27, P=0.030) and the secretion of perforin and granzyme B (t=72.50, U=52.50, both P<0.05). In the direct- and indirect-contact co-culture systems, compared with HBV-specific CD8+ T cells from the patients without HBsAg clearance, the HBV-specific CD8+ T cells from patients with HBsAg clearance had a significantly greater reduction in HBV DNA (P<0.05) and significant increases in the secretion of interferon-γ and tumor necrosis factor-α (P<0.05). ConclusionPEG-IFN-α-2b therapy can help to achieve a relatively high HBsAg clearance rate in HBeAg-negative patients with chronic HBV infection, and the activity of HBV-specific CD8+ T cells is significantly enhanced, which is closely associated with HBsAg clearance.
