Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

Objective To construct a recombinant poxvirus vector vaccine, rVTTδTK-RBD, and to evaluate its safety and immunogenicity. Methods The receptor-binding domain (RBD) gene was synthesized with reference to the gene sequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was inserted into the polyclonal site of the self-constructed recombinant plasmid pSTKE, to construct the recombinant poxvirus shuttle vector pSTKE-RBD. This was then transfected into BHK-21 cells pre-infected with the vaccinia virus Tiantan strain (VTT). The recombinant poxvirus rVTTδTK-RBD was successfully obtained after several rounds of fluorescence phage screening. The effect of rVTTδTK-RBD on the body mass of BALB/c mice was detected after immunizing mice by intra-nasal vaccination. The levels of specific and neutralizing antibodies produced by rVTTδTK-RBD on BALB/c mice were analyzed after immunizing mice intramuscularly. The effect of rVTTδTK-RBD on T cell subsets in BALB/c mice was detected by flow cytometry. Results Through homologous recombination, enhanced green fluorescent protein (EGFP) screening marker, and multiple rounds of fluorescent phosphorescence phage screening, a recombinant poxvirus rVTTδTK-RBD, expressing RBD with deletions in the thymidine kinase (TK) gene, was successfully obtained, which was validated by PCR. The in vivo experiments on BALB/c mice showed that rVTTδTK-RBD was highly immunogenic against SARS-CoV-2 and significantly reduced toxicity to the body compared to the parental strain VTT. Conclusion The recombinant poxvirus vaccine rVTTδTK-RBD against SARS-CoV-2 is successfully constructed and obtained, with its safety and immunogenicity confirmed through various experiments.

italic>Schisandra chinensis is a traditional Chinese medicine with the functions of reinforcing deficiency, strengthening, and inducing astringency, appliable to treat the chronic cough and deficiency in breath, palpitation, and insomnia, etc. A hybrid mass spectrometry scanning strategy (high-definition data-independent/data-dependent acquisition, HDDIDDA), enabling the ion mobility separation and alternating data-independent acquisition/data-dependent acquisition, was established, which, in combination with in-house library-driven automatic peak annotation workflows facilitated by the UNIFI software, was utilized to systematically characterize the multi-classes of chemical components from S. chinensis. The use of an HSS T3 column (100 mm × 2.1 mm, 1.8 μm), 0.1% formic acid in H₂O-acetonitrile as the mobile phase running at the flow rate of 0.3 mL·min^-1, and column temperature at 35 ℃, could enable good separation of the S. chinensis components within 42 min. HDDIDDA scan in both the positive and negative ion modes was employed for data acquisition. Based on the automatic peak annotation, reference standards comparison, MS² data interpretation, and literature analysis, we were able to identify or tentatively characterize 105 compounds in the S. chinensis decoction, involving 56 terpenoids, 42 lignans, five glycosides, one organic acid, and one flavonoid. HDDIDDA scanning can improve the coverage of data acquisition and improve the accuracy of identification, while CCS prediction analysis provides the possibility to distinguish isomers by the ion mobility technology. The results provide reference for the intelligent material basis research of TCM.

Objective:To analyze epidemiological characteristics and spatiotemporal clustering of hepatitis A in China from 2005 to 2023.Methods:The incidence data of hepatitis A in China during 2005-2023 were collected from the China Disease Control and Prevention Information System .Results:From 2005 to 2023, a total of 605 509 cases of hepatitis A were reported in China. The average annual reported incidence rate was 2.32/100 000, the incidence was 2.85/100 000 in men and 1.81/100 000 in women, and the incidence was 3.25/100 000 in age group 0-14 years, 2.10/100 000 in age group 15-64 years and 2.49/100 000 in age group ≥65 years , respectively. The case count in farmers was highest (40.57%, 245 639/605 509). The proportion of the cases in jobless or the unemployed increased most obviously (347.32%), and the proportion of the cases in students decreased most significantly (90.27%). The average annual reported incidence rate in the western China was highest (4.45/100 000), followed by that in northeastern China (2.02/100 000), central China (1.89/100 000) and eastern China (1.16/100 000). From 2020 to 2023, the incidence of hepatitis A showed no spatial clustering. From 2005 to 2019, the obvious hot spots and high-high clustering areas mainly distributed in provinces, such as, Sichuan, Qinghai, Xinjiang, Xizang and Gansu. The low-low clustering areas were mainly distributed in Beijing, Tianjin, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Henan, Anhui, Jiangxi, Jilin and Liaoning. An independent high-low clustering was found in Shanxi during 2014-2019. A total of 5 high incidence clustering areas were detected through spatiotemporal scanning analysis.Conclusions:The incidence rate of hepatitis A in China declined significantly from 2005 to 2023. The reported incidence rate in the elderly showed no obvious decrease, and the reported cases accounted for the highest proportion in the whole population. Before 2020, the reported incidence rate of hepatitis A showed high-high clustering in western China, the spatiotemporal clustering disappeared from 2020 to 2023, but the reported incidence rate of hepatitis A in western China was still high. It is suggested to pay attention to the prevention and control of hepatitis A in populations at high risk and areas with high incidence of hepatitis A.

Objective To explore the role and potential mechanisms of all-trans retinoic acid(ATRA)on activation and oxidative stress of hepatic stellate cell(HSC).Methods Platelet-derived growth factor(PDGF-bb,10 ng/ml)was applied to induce the activation of HSCs,which was then treated with ATRA at a dosage of 5 μmol/L for 48 h.The effects of ATRA on HSC activation were evaluated by detecting changes in cell growth viability and phenotypic marker expression.The effects of ATRA on HSC oxidative stress were evaluated by detecting changes in intracellular reactive oxygen species(ROS),reduced glutathione(GSH)and malondialdehyde(MDA),and the expression of antioxidant genes.The effects of ATRA on HSC autophagic activity were evaluated by detecting changes in autophagy marker expression and autophagic flow.Results Compared with the PDGF-bb group,the cell viability was significantly reduced in ATRA-treated HSCs(P＜0.01),as well as the expression of α-SMA and Collagen I.The intracellular levels of ROS and MDA were significantly reduced in ATRA-treated HSCs(P＜0.01),whereas the GSH level was significantly increased(P＜0.01).The expression levels of antioxidant genes(NRF2,HO-1,and ATF4),were significantly higher in ATRA-treated HSCs than those in the normal ones under PDGF-bb condition(P＜0.01).Meanwhile,the expression of autophagy markers Beclin 1 and LC3 Ⅱ/I,and signal of autophagy flow in ATRA-treated HSCs were found to be significantly reduced(P＜0.01).Conclusion ATRA significantly inhibited PDGF-bb-induced HSC activation and reduced the level of oxidative stress and autophagic activity of HSCs,which had potential applications in the prevention and treatment of liver fibrosis.

Objective To investigate the family aggregation of human hookworm infections in Sichuan Province and to identify its influencing factors, so as to provide insights into management of hookworm infections. Methods Three to four counties (districts) were sampled from basins, hilly regions and mountainous regions around the basins in Sichuan Province from 2017 to 2022 as fixed survey sites, and 17 to 30 counties (districts) were selected as mobile survey sites. At least 1 000 permanent residents at ages of 3 years and older were sampled from each survey site, and hookworm eggs were detected in human stool samples using the Kato-Katz technique. Subjects with 2 and more family members and at least 2 individuals diagnosed with hookworm infections in the county (district) where they lived were selected, and the familial aggregation of hookworm infections was analyzed using the test of goodness of fit for binomial distribution. In addition, the knowledge and practice of hookworm disease control were investigated among residents in Hejiang County and Wutongqiao District, Leshan City, Sichuan Province in 2021 and 2022, and the difference in the knowledge and practice of hookworm disease control was compared between members with and without familial aggregation of hookworm infections. Results A total of 66 812 residents from 25 196 households were sampled from main endemic areas of hookworm diseases in Sichuan Province from 2017 to 2022 for detection of hookworm infections, and 4 403 infections were identified (6.59% prevalence). The distribution of human hookworm infections in Sichuan Province did not fit the binomial distribution, and showed family aggregations (χ² = 2 116.759, P < 0.001). Family aggregation of human hookworm infections was found in endemic areas with 1% and higher prevalence of human hookworm infections (χ² = 136.006 to 428.738, all P values < 0.001), and family aggregation of human hookworm infections was identified in different years (χ² = 87.615 to 471.838, all P values < 0.001) and in different terrains of endemic areas (χ² = 8.423 to 1 144.176, all P values < 0.001). The members with hookworm infections had median eggs per gram of 180 (interquartile range, 780) in aggregated families and 72 (102) in non-aggregated families (Z = −2.686, P < 0.05). The proportion of members in families with aggregation of hookworm infections who knew the preventive measures of hookworm disease was significantly lower than in non-aggregated families (24.49% vs. 51.72%; χ² = 10.262, P < 0.05), and the proportion of members in families with aggregation of hookworm infections who often worked barefoot on the ground was significantly higher than in non-aggregated families (30.61% vs. 13.25%; χ² = 6.289, P < 0.05). Conclusions There is a familial aggregation of human hookworm infections in Sichuan Province, and awareness of preventive measures for hookworm disease and frequent working barefoot on the ground are associated with familial aggregation of hookworm infections.
