Objective To investigate the incidence trends and influencing factors of non-alcoholic fatty liver disease (NAFLD) -related cirrhosis in China, predict future disease burden, and provide evidence for public health prevention strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we employed joinpoint regression analysis to analyze NAFLD-related cirrhosis trends in China from 1990 to 2021, quantified influencing factors using age-period-cohort modeling, and predicted future incidence through Bayesian age-period-cohort analysis. Results The age-standardized incidence rates (ASIRs) of NAFLD-related cirrhosis showed a persistent increase from 1990 to 2021, with annual percentage changes (APCs) of 0.70% for male and 0.79% for female(both P<0.05). Age-effects revealed a U-shaped variation pattern, peaking in the 60-69 age group. Period effects indicated an incidence peak during 2017-2021. Cohort effects showed the most prominent risk in the 1992-1996 birth cohort. Projections suggested ASIR would further increase to 578.40 and 930.61 per 100 000 population for males and females, respectively, by 2030. Conclusions The disease burden of NAFLD-related cirrhosis continues to worsen in China, with future incidence rates projected to keep rising. Priority attention should be given to middle-aged and elderly populations and sex differences, with targeted prevention and control measures needing to be developed.

OBJECTIVE:
To investigate the detection patterns, clinical phenotypic characteristics, and differences in diagnostic timeliness of Klinefelter syndrome (KS) across prenatal and postnatal stages, with an aim to provide a basis for optimizing strategies for early screening, diagnosis, and intervention.
METHODS:
A retrospective study was conducted to analyze data from two phases. The prenatal diagnosis group included 33,302 pregnant women who underwent amniocytic karyotyping due to advanced maternal age, abnormal ultrasound findings, or high-risk non-invasive prenatal testing (NIPT). The postnatal diagnosis group included 52,101 patients who underwent peripheral blood karyotyping due to primary infertility, abnormal external genitalia, or growth and developmental abnormalities. Additionally, medical histories of adult diagnosed patients were reviewed retrospectively to identify early occult symptoms. This study was approved by the Medical Ethics Committee of Chengdu Women's and Children's Central Hospital (Ethics No.: LCYJ-2025-030).
RESULTS:
In the prenatal group, 96 cases of KS were detected (detection rate 0.29%). The primary indications for referral were NIPT indicating sex chromosome abnormalities (45.83%), advanced maternal age (16.66%), and ultrasound abnormalities (17.70%). In the postnatal group, 128 cases of KS were detected (detection rate 0.25%). Clinical presentations were primarily primary infertility/azoospermia (77.34%), and the patients were predominantly adults (84.40%). Retrospective analysis revealed that adult patients presented with specific physical signs that had been overlooked during childhood.
CONCLUSION
As KS lacks typical early clinical manifestations, diagnosis is often delayed until adulthood when reproductive needs arise, showing a pattern of "passive detection" and resulting in missed opportunities for optimal intervention. By conducting a comparative analysis of prenatal diagnostic data and postnatal retrospective data, a risk association model linking prenatal screening indications with childhood-specific signs was developed. This study has provided empirical evidence for establishing a multidisciplinary, full life-cycle management system of "screening ~ diagnosis ~ monitoring ~ intervention" helping to shift from "passive detection in adulthood" to "proactive management across the entire life course," and laid a foundation for improving early diagnosis rate and long-term quality of life for patients.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

Objective To explore the safety and effects of alpha-lipoic acid (ALA) in patients with ischemic heart failure (IHF). Methods A randomized, double-blind, placebo-controlled trial was designed (ClinicalTrial.gov registration number NCT03491969). From January 2019 to January 2023, 300 patients with IHF were enrolled in four medical centers in China, and were randomly assigned at a 1∶1 ratio to receive ALA (600 mg daily) or placebo on top of standard care for 24 months. The primary outcome was the composite outcome of hospitalization for heart failure (HF) or all-cause mortality events. The second outcome included non-fatal myocardial infarction (MI), non-fatal stroke, changes of left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) from baseline to 24 months after randomization. Results Finally, 138 patients of the ALA group and 139 patients of the placebo group attained the primary outcome. Hospitalization for HF or all-cause mortality events occurred in 32 patients (23.2%) of the ALA group and in 40 patients (28.8%) of the placebo group (HR=0.753, 95%CI 0.473-1.198, P=0.231; Figure 1A-1C). The absolute risk reduction (ARR) was 5.6%, the relative risk reduction (RRR) associated with ALA therapy was approximately 19.4% compared to placebo, corresponding to a number needed to treat (NNT) of 18 patients to prevent one event. In the secondary outcome analysis, the composite outcome of the major adverse cardiovascular events (MACE) including the hospitalization for HF, all-cause mortality events, non-fatal MI or non-fatal stroke occurred in 35 patients (25.4%) in the ALA group and 47 patients (33.8%) in the placebo group (HR=0.685, 95%CI 0.442-1.062, P=0.091; Figure 1D). Moreover, greater improvement in LVEF (β=3.20, 95%CI 1.14-5.23, P=0.002) and 6MWD (β=31.7, 95%CI 8.3-54.7, P=0.008) from baseline to 24 months after randomization were observed in the ALA group as compared to the placebo group. There were no differences in adverse events between the study groups. Conclusions These results show potential long-term beneficial effects of adding ALA to IHF patients. ALA could significantly improve LVEF and 6MWD compared to the placebo group in IHF patients.

ObjectiveTo investigate the effects of Shegan Mahuangtang and its pungent and bitter Chinese herbs on the expression of transient receptor potential vanilloid-1 (TRPV1) and bitter taste receptor 14 (TAS2R14) in the lung tissue of the rat model of cold asthma. MethodSeventy SD rats were randomized into 7 groups: normal, model, Shegan Mahuangtang, pungent Chinese herbs, bitter Chinese herbs (6.43 g·kg-1), dexamethasone (0.5 g·kg-1), and Guilong Kechuanning (10 g·kg-1). The rat model of cold asthma was established by intraperitoneal injection and subcutaneous injection of 10% ovalbumin (OVA) and aluminium hydroxide in the limbs, combined with 2% OVA atomization and cold (2-4 ℃) stimulation. The rats were treated with corresponding drugs by gavage and atomization, and the normal and model groups were treated with the same amount of normal saline for 3 weeks. After the last excitation, airway inflammation and cell proliferation were observed by hematoxylin-eosin (HE), periodic acid-Schiff (PAS), and Masson staining of the lung tissue. The levels of interleukin-5 (IL-5), tumor necrosis factor-α (TNF-α), thymic stromal lymphopoietin (TSLP), and transforming growth factor-β1 (TGF-β1) in the serum were measured by enzyme-linked immunosorbent assay (ELISA). The expression of TRPV1 and TAS2R14 was detected by immunofluorescence. The expression of TRPV1, TAS2R14, phospholipase Cβ2 (PLCβ2), B-cell lymphoma-2 (Bcl-2), and α-smooth muscle actin (α-SMA) in the lung tissue was determined by Western blot. ResultCompared with the normal group, the model group showed decreased water intake, food intake, and body weight, increased airway inflammatory cell infiltration, goblet cell proliferation, tissue fibrosis and collagen deposition, elevated levels of IL-5, TNF-α, TSLP, and TGF-β1 in the serum (P<0.01), upregulated expression of TRPV1, PLCβ2, and α-SMA, and downregulated expression of TAS2R14 and Bcl-2 (P<0.05, P<0.01). Compared with model group, Shecgan Mahuangtang, pungent Chinese herbs, and bitter Chinese herbs increased the water intake, food intake, and body weight, reduced the inflammatory cell infiltration and goblet cell proliferation, alleviated tissue fibrosis and collagen deposition, lowered the levels of IL-5, TNF-α, TSLP, and TGF-β1 in the serum (P<0.01), downregulated the expression of TRPV1, PLCβ2, and α-SMA, and upregulated the expression of TAS2R14 and Bcl-2 (P<0.05, P<0.01). ConclusionShegan Mahuangtang and its pungent and bitter Chinese herbs can reduce OVA-induced airway inflammation, downregulate the expression of TRPV1, PLCβ2, and α-SMA, and upregulate the expression of TAS2R14 and Bcl-2 in asthmatic rats. Moreover, bitter Chinese herbs outperformed pungent Chinese herbs, and the combination of them enhanced the therapeutic effect. It is suggested that Shegan Mahuangtang and its pungent and bitter Chinese herbs may ameliorate the OVA-induced airway inflammation by inhibiting TRPV1 and activating TAS2R14.

Objective To systematically summarize the published literature on the genetic variants associated with nonalcoholic fatty liver disease(NAFLD). Methods Literature from Web of Science,PubMed,and Embase between January 1980 and September 2022 was systematically searched.Meta-analyses of the genetic variants were conducted using at least five data sources.The epidemiologic credibility of the significant associations was graded using the Venice criteria. Results Based on literature screening,399 eligible studies were included,comprising 381 candidate gene association,16 genome-wide association,and 2 whole-exome sequencing studies.We identified 465 genetic variants in 173 genes in candidate gene association studies,and 25 genetic variants in 17 genes were included in the meta-analysis.The meta-analysis identified 11 variants in 10 genes that were significantly associated with NAFLD,with cumulative epidemiological evidence of an association graded as strong for two variants in two genes(HFE,TNF),moderate for four variants in three genes(TM6SF2,GCKR,and ADIPOQ),and weak for five variants in five genes(MBOAT7,PEMT,PNPLA3,LEPR,and MTHFR). Conclusion This study identified six variants in five genes that had moderate to strong evidence of an association with NAFLD,which may help understand the genetic architecture of NAFLD risk.

Objective:We genetically modified our non-replicating vaccinia virus NTV to improve its immunogenicity.Methods:We constructed NTV-modified strain NTV-ΔF1L-C7L by homologous recombination of vaccinia virus based on CRISPR-Cas9 technology by inserting the C7L gene while deleting the F1L gene. The recombinant virus NTV-ΔF1L-C7L was then immunized with 10 7 PFU in BALB/c mice, and the levels of humoral and cellular immunity induced by NTV-ΔF1L-C7L were detected by ELISA and ELISpot method, respectively, and the levels of neutralizing antibodies were determined by the phage-reduced neutralization assay. Results:The PCR and western- blot identification proved that the F1L gene of the constructed NTV-modified strain NTV-ΔF1L-C7L was missing, while the C7L gene was inserted back in the region, and the C7L gene could be expressed normally, indicating that the recombinant virus was constructed correctly. After immunization of mice with NTV-ΔF1L-C7L, ELISA result showed that the recombinant virus NTV-ΔF1L-C7L induced a higher level of IgG antibody than NTV; ELISpot result also showed that the recombinant virus was able to induce a higher level of IFN-γ; and the result of plaque reduction neutralization test showed that the recombinant virus was able to induce a higher level of IFN-γ antibody than that of NTV.Conclusions:We correctly constructed the NTV gene-modified strain NTV-ΔF1L-C7L, which induced stronger humoral and cellular immunity compared with NTV, and provided reference data for the research and development of replacement products for smallpox or monkeypox vaccines.

OBJECTIVE To investigate the effect and mechanism of gracillin from Reineckia carnea on autophagy in non- small cell lung cancer A549 cells. METHODS Using A549 cells as subjects, the effects of different concentrations of gracillin (0.25, 0.5, 1, 2, 4 μmol/L) on the proliferation of cells were detected by CCK-8 after being treated for different time (12, 24, 48 h). Compared with the control group without medication, the effect of gracillin (2 μmol/L) on the formation of autophagosomes in cells was observed by transmission electron microscope after 24 h of exposure. The aggregation of GFP-LC3 on autophagosome membrane was detected by GFP-LC3 plasmid transfection after being treated with gracillin (0.25, 0.5, 1, 2 μmol/L) for 24 h. Quantitative real-time PCR and Western blot assay were used to detect the mRNA and protein expressions of family with sequence similarity 102 member A(FAM102A), the expressions of autophagy-related proteins [p62, Beclin-1, microtubule-associated protein 1 light chain 3B (LC3B)], and the expressions of phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway-related proteins in A549 cells after being treated with gracillin (0.25, 0.5, 1 and 2 μmol/L) for 24 h. RESULTS Gracillin significantly inhibited the proliferation of A549 cells in a concentration- and time-dependent manner. The IC50 was 2.55 μmol/L at 24 h. After 24 h of gracillin treatment, autophagosomes with bilayer membrane structure were found in the cell cytoplasm, and GFP-LC3 green fluorescent spots on autophagosome membrane were obvious, representing an increasing trend as drug concentration. Compared with the control group, mRNA and protein expressions of FAM102A (0.5, 1, 2 μmol/L groups), protein expression of Beclin-1 (1, 2 μmol/L groups) and LC3B-Ⅱ/LC3B-Ⅰ ratio (2 μmol/L group) were significantly increased in different concentrations of gracillin groups, while the protein expression of p62 (1, 2 μmol/L groups), and the protein phosphorylations of Akt (1, 2 μmol/L groups) and PI3K (2 μmol/L group) were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS Gracillin can promote excessive autophagy in A549 cells by up-regulating mRNA and protein expressions of FAM102A and inhibiting PI3K/Akt signaling pathway, thus inhibiting cell proliferation.
