BACKGROUND:Autophagy,as a key regulatory mechanism of cell development,plays an important role in different stages of embryonic development.The mechanism of how autophagy regulates embryonic development through histone modifications is currently unclear.OBJECTIVE:To investigate the effect of autophagy on trimethylation of lysine 4 on histone H3(H3K4me3)modification in embryos and its effect on embryonic development.METHODS:Mouse fertilized eggs were divided into control and autophagy inhibitor-treated groups(chloroquine phosphate-treated group and 3-methyladenine-treated group),and cultured in vitro to different periods of time,and were then classified as early 2-cell embryos,middle 2-cell embryos,late 2-cell embryos,4-cell embryos,8-cell embryos,morula stage,and blastocyst stage.Levels of reactive oxygen species,autophagy marker proteins LC3B and P62,DNA loss marker γH2AX,and H3K4me3 were analyzed by immunofluorescence assay in late 2-cell embryos of each group.Changes in H3K4me3 modification in late 2-cell embryos of each group were detected by CUT&Tag.RESULTS AND CONCLUSION:(1)Autophagy inhibition caused embryo development arrest.(2)There was no significant difference in reactive oxygen species and γH2AX between the autophagy inhibitor-treated groups and control group.(3)H3K4me3 levels were significantly elevated in the autophagy inhibitor-treated group compared with the control group.(4)CUT&Tag results showed a significantly increased H3K4me3 peaks on the proximal promoter region of the genes after autophagy inhibition and an increase of H3K4me3-specific modification genes.These findings suggest that autophagy may affect embryonic development by regulating the level of H3K4me3 modification.

Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

Purpose: This study aims to examine the prevalence of overweight and obesity in children with type 1 diabetes mellitus (T1DM) in Hong Kong and to evaluate the association between obesity, glycemic control, and metabolic comorbidities. Methods: A retrospective cross-sectional study was conducted from 2022–2023 at the Hong Kong Children’s Hospital, enrolling all children with T1DM. Anthropometric measurements and biochemical data were extracted from medical records, and prevalence rates of metabolic complications were compared. Results: One hundred twenty-six children (41% male, 89% Asian) with a median age of 12.8 years were included. Of these, 17.5% were either overweight or obese. There were no significant differences in hemoglobin A1c values between the normal-weight and overweight/obesity groups, though the latter group required higher total daily insulin doses. Children with overweight/obesity had higher prevalence rates of hypertension (28.6% vs. 2.9%) and dyslipidemia (90.5% vs. 71.9%). They were also more likely to have hypertension (adjusted odds ratio [aOR], 18.48; 95% confidence interval [CI], 3.42–99.94) and hypertriglyceridemia (aOR, 7.71; 95% CI, 1.66–35.76). The overweight/obese group also exhibited significantly higher alanine aminotransferase levels (median, 18 IU/L vs. 14 IU/L), non–high-density lipoprotein cholesterol (HDL-C) levels (median, 3.3 mmol/L vs. 2.9 mmol/L), and triglyceride/HDL-C ratios (median, 1.09 vs. 0.52) and lower HDL-C levels (median, 1.4 mmol/L vs. 1.6 mmol/L). Among those with dyslipidemia, only 8% were started on lipid-lowering agents, while none of those with hypertension were started on antihypertensive agents. Conclusion Despite a lower prevalence of overweight/obesity in Asian children with T1DM compared to Western populations, metabolic comorbidities occur at an exceptionally high rate. Early interventions to tackle these modifiable cardiovascular risk factors are crucial to prevent long-term complications.

Acute lung injury （ALI） is one of the most common and critical diseases in clinical practice， with extremely high morbidity and mortality， seriously threatening human life and health. The pathogenesis of ALI is complex， in which the inflammatory response is a key factor. Studies have shown that NOD-like receptor protein 3 （NLRP3） inflammasomes are involved in ALI through mechanisms such as inflammation induction， increased microvascular permeability， recruitment of neutrophils， oxidative stress， and pyroptosis， playing a key role in the occurrence and progression of ALI. Therefore， regulating NLRP3 inflammasomes and inhibiting the release of inflammatory factors can alleviate the damage in ALI. At present， ALI is mainly treated by mechanical ventilation and oxygen therapy， which have problems such as high costs and poor prognosis. In recent years， studies have shown that traditional Chinese medicine （TCM） can reduce the inflammatory response and the occurrence of oxidative stress and pyroptosis by regulating the NLRP3 inflammasome， thus alleviating the damage and decreasing the mortality of ALI. Based on the relevant literature in recent years， this article reviews the research progress in TCM treatment of ALI by regulating NLRP3 inflammasomes， discusses how NLRP3 inflammasomes participate in ALI， and summarizes the active ingredients， extracts， and compound prescriptions of TCM that regulate NLRP3 inflammasomes， aiming to provide new ideas for the clinical treatment of ALI and the development of relevant drugs.

Innovative drugs are defined as new chemical entities that play a vital role in the treatment and maintenance of human health. While single-target innovative drugs have achieved notable success, they face limitations in addressing the increasingly complex and precise spectra of diseases. The advent of multi-target innovative drugs offers new opportunities, supported by a growing body of pharmacological evidence. Herbal medicines are recognized as valuable sources of multi-target therapeutics due to their proven efficacy in treating complex diseases. However, the identification and validation of such drugs from herbal sources continue to pose significant challenges. This paper presents a comprehensive review of the literature on traditional Chinese medicine, integrated medicine, chemistry, and biology from 2015 to 2025. It summarizes the strategies employed in integrating traditional Chinese and Western medicine for innovative drug development, along with successful application cases. We believe these efforts will deepen understanding of the current landscape, accelerate the discovery of multi-target innovative drugs from herbal medicine, and contribute to addressing major human health challenges.

Guided by the cancer toxin theory of TCM master Professor Zhou Zhongying,and absorbing the thoughts of academician Tong Xiaolin's theory of state-target,the pathogenesis of multiple myeloma is summarized as deficiency of healthy qi,bone erosion and marrow damage,cancer toxin accumulation,phlegm and stasis mingling,the combat between healthy qi and evil qi,and dynamic evo-lution;a full-cycle anti-cancer and detoxification prevention and treatment strategy for multiple myeloma is proposed that incorporates the ideas of nourishing deficiency and strengthening healthy qi,preventing cancer and detoxification,resolving phlegm and removing stasis throughout the entire treatment process.The scientific connotation of the pathogenesis theory of"healthy qi deficiency and cancer toxin"in multiple myeloma is explained from multiple aspects such as protein overload and tumor microenvironment,and a prescrip-tion-drug medicine system with Xuanbi Xiaoliu Formula as the core is constructed,which provides new ideas and scientific basis for the clinical diagnosis and treatment plan and full-cycle prevention and control model of multiple myeloma combining Chinese and West-ern medicine.

Objective:To understand the current situation of the ability to screen health information of the elderly in rural areas and analyze its influencing factors, so as to provide a basis for taking targeted measures.Methods:A cross-sectional survey was adopted, and rural elderly people in Yonghe Town, Dahu Town and Dayao Town of Liuyang City, Hunan Province were selected as the survey subjects by the convenience sampling method. The investigation was conducted using the general information Questionnaire, the Health Information Discrimination Ability Scale, the filial Piety Expectation Scale and the two-way Social Support Scale.Results:A total of 228 questionnaires were distributed, and 215 valid questionnaires were retrieved, with an effective recovery rate of 94.30%. Among the 215 rural elderly people surveyed, 86 were male and 129 were female. The ability to discriminate health information was (69.19 ± 13.41) points, the expectation of filial piety was (37.67 ± 6.12) points, and the two-way social support was (46.82 ± 8.11) points. The ability of rural elderly people to discriminate health information was positively correlated with filial piety expectations and two-way social support ( r = 0.340, 0.456; both P<0.01). The results of hierarchical regression analysis showed that educational level, filial piety expectations and two-way social support were the influencing factors of the current status of health information discrimination ability of rural elderly people ( t values were 2.60 to 5.35, all P<0.05). Conclusions:The ability of discriminating health information of the elderly in rural areas is affected by the educational level, filial piety expectation and two-way social support. The health information of rural elderly people with low education level should be screened and targeted, so as to enrich their cultural life and combine education with fun. Actively build a filial piety culture to promote children′s attention to their parents. In addition to providing social support for the elderly, we should promote their interpersonal and social communication and exert their self-value, so as to improve the health information screening ability of the elderly in rural areas.
