    Abstract Idiopathic pulmonary fibrosis (IPF) is a globally prevalent, progressive disease with limited treatment options and poor prognosis. Because of its irreversible disease progression, IPF affects the quality and length of life of patients and imposes a significant burden on their families and social healthcare services. The use of the antifibrotic drugs pirfenidone and nintedanib can slow the progression of the disease to some extent, but it does not have a reverse effect on the prognosis. The option of lung transplantion is also limited owing to contraindications to transplantation, possible complications after transplantation, and the risk of death. Therefore, the discovery of new, effective treatment methods is an urgent need. Over recent years, various studies have been undertaken to investigate the relationship between interstitial pneumonia and lung cancer, suggesting that some immune checkpoints in IPF are similar to those in tumors. Immune checkpoints are a class of immunosuppressive molecules that are essential for maintaining autoimmune tolerance and regulating the duration and magnitude of immune responses in peripheral tissues. They can prevent normal tissues from being damaged and destroyed by the immune response. While current studies have focused on PD-1/PD-L1 and CTLA-4, PD-1/PD-L1 may be the only effective immune checkpoint IPF treatment. This review discusses the application of PD-1/PD-L1 checkpoint in IPF, with the aim of finding a new direction for IPF treatment.

    Abstract Diabetes mellitus is a chronic metabolic disorder marked by hyperglycemia and systemic complications, including hepatic dysfunction, significantly contributing to disease progression and morbidity. This article reviews recent advances in gene-based therapeutic strategies targeting hepatic complications in diabetes, offering a promising approach for precision medicine by addressing underlying molecular mechanisms. Traditional treatments for hepatic complications in diabetes often manage symptoms rather than molecular causes, showing limited efficacy. Gene-based therapies are poised to correct dysfunctional pathways and restore hepatic function. Fundamental gene therapy approaches include gene silencing via small interfering RNAs (siRNAs) to target hepatic glucose production, lipid metabolism, and inflammation. Viral vectors can restore insulin sensitivity and reduce oxidative stress in diabetic livers. Genome editing, especially CRISPR-Cas9, allows the precise modification of disease-associated genes, offering immense potential for hepatic complication treatment. Strategies using CRISPR-Cas9 to enhance insulin receptor expression and modulate aberrant lipid regulatory genes are explored. Safety challenges in gene-based therapies, such as off-target effects and immune responses, are discussed. Advances in nanoparticle-based delivery systems and targeted gene editing techniques offer solutions to enhance specificity and minimize adverse effects. In conclusion, gene-based therapeutic approaches are a transformative direction in managing hepatic complications in diabetes. Further research is needed to optimize efficacy, safety, and long-term outcomes. Nevertheless, these innovative strategies promise to improve the lives of individuals with diabetes by addressing hepatic dysfunction's genetic root causes.

    Abstract Short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate, have emerged as critical mediators in the communication between the human microbiota and its host. As the first responder to the inflammatory site, neutrophils play an important role in protecting the host against bacterial infections. Recent investigations revealed that SCFAs generated from microbiota influence various neutrophil activities, including activation, migration, and generation of mediators of inflammatory processes. SCFAs have also been demonstrated to exhibit potential therapeutic benefits in a variety of disorders related to neutrophil dysfunction, including inflammatory bowel disease, viral infectious disorders, and cancer. This study aims to examine the molecular processes behind the complicated link between SCFAs and neutrophils, as well as their influence on neutrophil-driven inflammatory disorders. In addition, we will also provide an in-depth review of current research on the diagnostic and therapeutic value of SCFAs as possible biomarkers for neutrophil-related diseases.

    Abstract Background: S100A12, S100A8, and S100A9 are inflammatory disease biomarkers whose functional significance in idiopathic pulmonary fibrosis (IPF) remains unclear. We evaluated the significance of S100A12, S100A8, and S100A9 levels in IPF development and prognosis.
    Methods: The dataset was collected from the Gene Expression Omnibus (GEO) database and differentially expressed genes were screened using GEO2R. We conducted a retrospective study of 106 patients with IPF to explore the relationships between different biomarkers and poor outcomes. Pearson's correlation coefficient, Kaplan-Meier, Cox regression, and functional enrichment analyses were used to evaluate relationships between these biomarkers' levels and clinical parameters or prognosis.
    Results: Serum levels of S100A12, S100A8, and S100A9 were significantly elevated in patients with IPF. The two most significant co-expression genes of S100A12 were S100A8 and S100A9. Patients with levels of S100A12 (median 231.21 ng/mL), S100A9 (median 57.09 ng/mL) or S100A8 (median 52.20 ng/mL), as well as combined elevated S100A12, S100A9, and S100A8 levels, exhibited shorter progression-free survival and overall survival. Serum S100A12 and S100A8, S100A12 and S100A9, S100A9 and S100A8 concentrations also displayed a strong positive correlation (r
    Conclusions: S100A12, S100A8, and S100A9 are promising circulating biomarkers that may aid in determining IPF patient prognosis. Multicenter clinical trials are needed to confirm their clinical value.

    Abstract Hepatitis B virus (HBV) reactivation is a clinically significant challenge in disease management. This review explores the immunological mechanisms underlying HBV reactivation, emphasizing disease progression and management. It delves into host immune responses and reactivation's delicate balance, spanning innate and adaptive immunity. Viral factors' disruption of this balance, as are interactions between viral antigens, immune cells, cytokine networks, and immune checkpoint pathways, are examined. Notably, the roles of T cells, natural killer cells, and antigen-presenting cells are discussed, highlighting their influence on disease progression. HBV reactivation's impact on disease severity, hepatic flares, liver fibrosis progression, and hepatocellular carcinoma is detailed. Management strategies, including anti-viral and immunomodulatory approaches, are critically analyzed. The role of prophylactic anti-viral therapy during immunosuppressive treatments is explored alongside novel immunotherapeutic interventions to restore immune control and prevent reactivation. In conclusion, this comprehensive review furnishes a holistic view of the immunological mechanisms that propel HBV reactivation. With a dedicated focus on understanding its implications for disease progression and the prospects of efficient management strategies, this article contributes significantly to the knowledge base. The more profound insights into the intricate interactions between viral elements and the immune system will inform evidence-based approaches, ultimately enhancing disease management and elevating patient outcomes. The dynamic landscape of management strategies is critically scrutinized, spanning anti-viral and immunomodulatory approaches. The role of prophylactic anti-viral therapy in preventing reactivation during immunosuppressive treatments and the potential of innovative immunotherapeutic interventions to restore immune control and proactively deter reactivation.

    Abstract Background: In recent years, the Chinese government has placed growing emphasis on environmental development. The implementation of effective waste separation practices in schools is crucial for establishing an ecological civilization in China.
    Objective: The present study aimed to assess the knowledge, attitude, and practice (KAP) of waste separation among Chinese university students and to understand the demographic factors influencing the KAP of the interviewed students. These sociodemographic factors include gender, age, education, and family environment.
    Methods: Based on the KAP theoretical model and the Lewin behavioral model (LBM), this study developed its questionnaire on college students' KAP of rubbish sorting. A survey was conducted on 1,282 college students from five colleges and universities in Beijing. A one-way ANOVA, Pearson's correlation analysis, and multiple linear stepwise regression analyzes were employed to explore the factors influencing college students' KAP scores on waste sorting. The questionnaire's reliability and validity were effectively verified through two rounds of Delphi expert consultation.
    Results: The scores for KAP dimensions were 55.64, 69.18, and 54.8%, respectively. The overall KAP score of university students in waste classification was 46.93 ± 9.93, with a percentage score of 62.57%. More than half of the college students lack a clear understanding of waste classification. Grade, gender, major, highest family education, and family economic status all influence college students' KAP scores on waste classification. There is a notable deficiency in school education regarding waste classification, with only 30.7% reporting having received such education.
    Conclusion: This study unveils the overall KAP score of waste separation among Chinese college students, which is marginally acceptable. The interviewed students exhibit a positive attitude and a willingness to participate in waste separation. However, there is room for improvement in both knowledge and practices. A lack of knowledge about waste sorting emerges as the primary influence on individual-level practices. Consideration should be given to enhancing education and management of waste separation among college students, emphasizing the cultivation of an eco-conscious culture, and guiding students to establish correct ecological values.

    Abstract Background: Zinc deficiency can lead to multiple organ damage. In this study, we investigated the effects of zinc deficiency on obesity-related lung damage.
    Methods: C57BL/6 J mice were fed a diet with differing amounts of zinc and fat over a 6-month period. Palmitic acid was used to stimulate A549 cells to construct a high-fat alveolar epithelial cell model. Western blotting and histopathological staining were performed on animal tissues. Nuclear expression of nuclear factor erythroid 2-related factor 2 (Nrf2) was detected in cultured cells. A reactive oxygen species (ROS) assay kit was used to detect intracellular ROS. Furthermore, Nrf2 siRNA was used to examine zinc deficiency effects on A549 cells.
    Results: Pathological results showed significant damage to the lung structure of mice in the high-fat and low-zinc diet group, with a significant increase in the expression of inflammatory (IL-6, TNF-α) and fibrosis (TGFβ1, PAI-1) factors, combined with a decrease in the expression of Nrf2, HO-1 and NQO1 in the antioxidant pathway. In A549 cells, high fat and low zinc levels aggravated ROS production. Western blot and immunofluorescence results showed that high fat and zinc deficiency inhibited Nrf2 expression. After Nrf2-specific knockout in A549 cells, the protective effect of zinc on oxidant conditions induced by high fat was reduced. Phosphorylated Akt and PI3K levels were downregulated on the high-fat and low-zinc group compared with the high-fat group.
    Conclusions: Zinc attenuated lung oxidative damage in obesity-related lung injury and Nrf2 activation is one of the important mechanisms of this effect.
    General significance: Regulating zinc homeostasis through dietary modifications or supplemental nutritional therapy can contribute to the prevention and treatment of obesity-related lung injury.

    Abstract Idiopathic pulmonary fibrosis (IPF) is a severe interstitial lung disease; although the recent introduction of two anti-fibrosis drugs, pirfenidone and Nidanib, have resulted in a significant reduction in lung function decline, IPF is still not curable. Approximately 2-20% of patients with IPF have a family history of the disease, which is considered the strongest risk factor for idiopathic interstitial pneumonia. However, the genetic predispositions of familial IPF (f-IPF), a particular type of IPF, remain largely unknown. Genetics affect the susceptibility and progression of f-IPF. Genomic markers are increasingly being recognized for their contribution to disease prognosis and drug therapy outcomes. Existing data suggest that genomics may help identify individuals at risk for f-IPF, accurately classify patients, elucidate key pathways involved in disease pathogenesis, and ultimately develop more effective targeted therapies. Since several genetic variants associated with the disease have been found in f-IPF, this review systematically summarizes the latest progress in the gene spectrum of the f-IPF population and the underlying mechanisms of f-IPF. The genetic susceptibility variation related to the disease phenotype is also illustrated. This review aims to improve the understanding of the IPF pathogenesis and facilitate his early detection.
