Chinese Journal of School Health 2026;47(1):90-93
Objective:
To explore the association between the cumulative effect of body mass index (BMI) in childhood and the frequency of elevated blood pressure and cumulative burden of blood pressure, so as to provide a basis for preventing high blood pressure in children.
Methods:
Data were derived from the "Cardiometabolic Risk Cohort Study" conducted from 2012 to 2018, which included all students from three nine year schools (comprising primary and secondary school) in Zigong City. A total of 1 583 students with normal blood pressure at baseline were included in the study. Questionnaires and physical examinations were administered to collect demographic information, BMI, systolic blood pressure (SBP), and diastolic blood pressure (DBP). Follow up surveys were conducted annually. To measure cumulative effects, the total area under the BMI curve (BMI-AUCt), cumulative burden of SBP (CB-SBP), and cumulative burden of DBP (CB-DBP) were calculated using the trapezoidal rule. Multinomial Logistic regression models were employed to analyze the relationship between BMI-AUCt and the frequency of elevated blood pressure during the follow up period. Additionally, multiple linear regression models combined with restricted cubic splines (RCS) were used to explore the dose response relationships of BMI-AUCt with CB-SBP and CB-DBP, respectively.
Results:
At baseline, the median ( IQR ) values for BMI, SBP and DBP of the students were 15.0(14.2, 16.1) kg/m 2 ,89.0(87.0, 90.0) mmHg and 58.0(54.0, 60.0 ) mmHg, respectively. During follow up, the median( IQR ) BMI, SBP and DBP for students with 0, 1 and ≥2 occurrences of high blood pressure were: 14.8(14.0, 15.9), 15.2(14.3, 16.3), 15.8(14.9, 17.0) kg/m 2; 89.0(87.0, 90.0),89.0(87.0,90.0), 89.0(87.0, 90.0)mmHg; 58.0(54.0, 60.0), 58.0(54.0, 59.5), 59.0(56.0, 59.0) mmHg. Results from the multinomial Logistic regression model, after adjusting for baseline age, sex, school, overweight/obesity status and number of measurements showed that compared to students with 0 occurrence of high blood pressure during follow up, for every 1 unit increase in BMI-AUCt, the risk of having 1 occurrence and ≥2 occurrences of high blood pressure increased by 4%( OR =1.04) and 6%( OR =1.06), respectively(both P <0.05). Multiple linear regression combined with restricted cubic splines(RCS) revealed non linear dose response relationships between BMI-AUCt and both CB-SBP and CB-DBP(all P trend <0.01, all P non linearity <0.01). Specifically, BMI-AUCt was positively correlated with CB-SBP when BMI-AUCt exceeded 30.08 kg/m 2×year( β =0.13) and with CB-DBP when BMI-AUCt exceeded 48.41 kg/m 2×year( β =0.12)(both P <0.01).
Conclusions
Children with a higher cumulative BMI may face an increased risk of cumulative blood pressure burden. It is necessary to enhance dynamic monitoring of children s BMI and blood pressure for reducing the risk of elevated blood pressure in childhood.

ObjectiveTo investigate the mechanisms by which Liuwei Buqi prescription (LWBQ) regulates alveolar macrophage efferocytosis and improves inflammatory responses in rats with chronic obstructive pulmonary disease (COPD) characterized by lung-kidney Qi deficiency based on the nuclear factor erythroid 2-related factor 2 (Nrf2)/macrophage receptor with collagenous structure (MARCO) pathway. MethodsSuccessfully modeled rats were randomly divided into a model group, low-dose LWBQ group (LWBQ-L, 2.25 g·kg-1·d-1), medium-dose LWBQ group (LWBQ-M, 4.5 g·kg-1·d-1), high-dose LWBQ group (LWBQ-H, 9 g·kg-1·d-1), and aminophylline group (AMIN, 50 mg·kg-1·d-1), with 8 rats in each group. Another 8 healthy rats were included as the blank group. Except for the blank group, rats in the remaining groups were subjected to smoke exposure combined with forced swimming, intratracheal lipopolysaccharide (LPS) instillation, and subcutaneous hydrocortisone injection to establish a COPD model with lung-kidney Qi deficiency. After successful modeling, rats were administered different doses of LWBQ or AMIN by gavage. Body weight, fur condition, and oral secretions were observed. Pulmonary function was measured using an animal lung function analyzer. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of interferon-γ (IFN-γ), interleukin-6 (IL-6), interleukin-1 (IL-1), and tumor necrosis factor-α (TNF-α) in bronchoalveolar lavage fluid (BALF) and serum (SER). Hematoxylin-eosin (HE) staining was used to examine pathological changes in lung tissue. Giemsa staining was performed to detect eosinophils, basophils, and neutrophils in BALF. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was used to detect apoptosis in lung tissue. Western blot and real-time polymerase chain reaction (Real-time PCR) were employed to determine the protein and mRNA expression levels of efferocytosis-related proteins growth arrest-specific gene 6 (GAS6), milk fat globule-epidermal growth factor 8 (MFG-E8), and pathway-related proteins Nrf2 and MARCO in lung tissue. ResultsCompared with the blank group, the model group showed reduced food intake, nasal and oral secretions with sputum, and decreased body weight (P<0.01), decreased peak expiratory flow (PEF) (P<0.01), increased forced vital capacity (FVC) (P<0.01), and decreased forced expiratory volume in 0.3 s/forced vital capacity [FEV0.3/FVC (%)] (P<0.01). The expression levels of IFN-γ, IL-6, IL-1, and TNF-α in BALF and SER were increased (P<0.01). Lung tissue exhibited structural destruction, hyperplasia, inflammatory exudation, increased apoptotic cells, and increased mean optical density (P<0.01). The protein and mRNA expression levels of GAS6, MFG-E8, and MARCO, as well as Nrf2 mRNA expression, were increased (P<0.01). Compared with the model group, the LWBQ groups showed increased food intake, reduced nasal and oral secretions with sputum, and increased body weight (P<0.05, P<0.01). PEF was increased (P<0.01). FVC was increased in rats treated with low- and medium-dose LWBQ (P<0.01), and FEV0.3/FVC (%) was increased in rats treated with medium- and high-dose LWBQ (P<0.05, P<0.01). The expression levels of IFN-γ, IL-6, IL-1, and TNF-α in BALF and SER were decreased (P<0.01). Lung tissue structure was relatively intact, with improvement in hyperplasia and inflammatory exudation. The number of apoptotic cells in lung tissue was reduced, and mean optical density was decreased (P<0.05, P<0.01). The protein and mRNA expression levels of efferocytosis-related proteins GAS6 and MFG-E8 and pathway-related proteins Nrf2 and MARCO were increased (P<0.01). ConclusionLWBQ can alleviate pulmonary and systemic inflammation, improve lung function, and reduce lung tissue damage in rats with COPD characterized by lung-kidney Qi deficiency. The mechanism may be related to enhancement of alveolar macrophage efferocytosis through regulation of the Nrf2/MARCO pathway.

Ulcerative colitis(UC) is a chronic non-specific inflammatory bowel disease characterized by inflammation and ulceration of the colonic mucosa and submucosa, and its complex pathogenesis involves immune abnormality, oxidative stress and other factors. The nuclear transcription factor E2-related factor 2(Nrf2), encoded by the Nfe212 gene, plays a central role in antioxidant responses. It not only activates various antioxidant response elements such as heme oxygenase-1(HO-1) and quinone oxidoreductase 1(NQO1), but also enhances the activity of glutathione-S-transferase(GST) and superoxide dismutase 1(SOD1), effectively eliminating reactive oxygen species(ROS) accumulated in the body, and mitigating oxidative stress-induced damage to intestinal mucosa. In addition, Nrf2 can reduce the release of inflammatory factors and infiltration of immune cells by regulating immune response, cell apoptosis and autophagy pathways, thereby alleviating intestinal inflammation and promoting the repair and regeneration of damaged mucosa. Based on this, this paper reviews the research progress of Chinese materia medica in the prevention and treatment of UC by modulating the Nrf2 signaling pathway. It deeply explores the physiological role of Nrf2, the molecular mechanism of activation, the protective effect in the pathological process of UC, and how active ingredients in Chinese materia medica regulate the Nrf2 signaling pathway through multiple pathways to exert their potential mechanisms. These studies have revealed in depth that Chinese materia medica can effectively combat oxidative stress by regulating the Nrf2 signaling pathway. It can also play a role in anti-inflammatory, promoting autophagy, inhibiting apoptosis, protecting the intestinal mucosal barrier, and promoting intestinal mucosal repair, providing new ideas and methods for the multi-faceted treatment of UC.

ObjectiveTo investigate the effects of Yiqi Wenyang Huoxue Lishui components on the cardiac function and mitochondrial energy metabolism in the rat model of chronic heart failure (CHF) and explore the underlying mechanism. MethodsThe rat model of CHF was prepared by transverse aortic constriction (TAC). Eight of the 50 SD rats were randomly selected as the sham group, and the remaining 42 underwent TAC surgery. The 24 SD rats successfully modeled were randomized into model, trimetazidine (6.3 mg·kg-1), and Yiqi Wenyang Huoxue Lishui components (60 mg·kg-1 total saponins of Astragali Radix, 10 mg·kg-1 total phenolic acids of Salviae Miltiorrhizae Radix et Rhizoma, 190 mg·kg-1 aqueous extract of Lepidii Semen, and 100 mg·kg-1 cinnamaldehyde) groups. The rats were administrated with corresponding agents by gavage, and those in the sham and model groups were administrated with the same amount of normal saline at a dose of 10 mL·kg-1 for 8 weeks. Echocardiography was used to examine the cardiac function in rats. Enzyme-linked immunosorbent assay was employed to determine the serum levels of N-terminal pro-B-type natriuretic peptide (NT-ProBNP), hypersensitive troponin(cTnI), creatine kinase (CK), lactate dehydrogenase (LD), free fatty acids (FFA), superoxide dismutase (SOD), and malondialdehyde (MDA). The colorimetric assay was employed to measure the levels of adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine monophosphate (AMP) in the myocardial tissue. The pathological changes in the myocardial tissue were observed by hematoxylin-eosin staining and Masson staining. The Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities in the myocardial tissue were determined by the colorimetric assay. The ultrastructural changes of myocardial mitochondria were observed by transmission electron microscopy. Western blot was employed to determine the protein levels of ATP synthase subunit delta (ATP5D), glucose transporter 4 (GLUT4), and carnitine palmitoyltransferase-1 (CPT-1). The mitochondrial complex assay kits were used to determine the activities of mitochondrial complexes Ⅰ, Ⅱ, Ⅲ, and Ⅳ. ResultsCompared with the sham group, the model group showed a loosening arrangement of cardiac fibers, fracture and necrosis of partial cardiac fibers, inflammatory cells in necrotic areas, massive blue fibrotic tissue in the myocardial interstitium, increased collagen fiber area and myocardial fibrosis, destroyed mitochondria, myofibril disarrangement, sparse myofilaments, and fractured and reduced cristae. In addition, the rats in the model group showed declined ejection fraction (EF) and fractional shortening (FS), risen left ventricular end-diastolic diameter (LVIDd), left ventricular end-systolic diameter (LVIDs), left ventricular end-diastolic posterior wall thickness (LVPWd), left ventricular end-systolic posterior wall thickness (LVPWs), left ventricular end-diastolic volume (LVVOLd), and left ventricular end-systolic volume (LVVOLs), elevated levels of NT-ProBNP, cTnI, CK, MDA, FFA, and LD, lowered level of SOD, down-regulated protein levels of GLUT4 and CPT-1, decreased activities of Na+-K+-ATPase, Ca2+-Mg2+-ATPase, and respiratory complexes Ⅰ-Ⅳ, and declined levels of ATP5D, ATP, ADP, and AMP (P<0.05, P<0.01). Compared with the model group, the Yiqi Wenyang Huoxue Lishui components and trimetazidine groups showed alleviated pathological damage of the mitochondria and mycardial tissue, risen EF and FS, declined LVIDd, LVIDs, LVPWd, LVPWs, LVVOLd, and LVVOLs, lowered levels of NT-ProBNP, cTnI, CK, MDA, FFA, and LD, elevated level of SOD, up-regulated protein levels of GLUT4 and CPT-1, increased activities of Na+-K+-ATPase, Ca2+-Mg2+-ATPase, and respiratory complexes Ⅰ-Ⅳ, and elevated levels of ATP5D, ATP, ADP, and AMP (P<0.05, P<0.01). ConclusionYiqi Wenyang Huoxue Lishui components can improve the cardiac function, reduce myocardial injury, regulate glucose and lipid metabolism, optimize the utilization of substrates, and alleviate the damage of mitochondrial structure and function, thus improving the energy metabolism of the myocardium in the rat model of CHF.

Diabetes is a very complex endocrine disease whose common feature is the increase in blood glucose concentration. Persistent hyperglycemia can lead to blindness, kidney and heart disease, neurodegeneration, and many other serious complications that have a significant impact on human health and quality of life. The number of people with diabetes is increasing yearly. The global diabetes prevalence in 20-79 year olds in 2021 was estimated to be 10.5% (536.6 million), and it will rise to 12.2% (783.2 million) in 2045. The main modes of intervention for diabetes include medication, dietary management, and exercise conditioning. Medication is the mainstay of treatment. Marketed diabetes drugs such as metformin and insulin, as well as GLP-1 receptor agonists, are effective in controlling blood sugar levels to some extent, but the preventive and therapeutic effects are still unsatisfactory. Peptide drugs have many advantages such as low toxicity, high target specificity, and good biocompatibility, which opens up new avenues for the treatment of diabetes and other diseases. Currently, insulin and its analogs are by far the main life-saving drugs in clinical diabetes treatment, enabling effective control of blood glucose levels, but the risk of hypoglycemia is relatively high and treatment is limited by the route of delivery. New and oral anti-diabetic drugs have always been a market demand and research hotspot. Inhibitor cystine knot (ICK) peptides are a class of multifunctional cyclic peptides. In structure, they contain three conserved disulfide bonds (C3-C20, C7-C22, and C15-C32) form a compact “knot” structure, which can resist degradation of digestive protease. Recent studies have shown that ICK peptides derived from legume, such as PA1b, Aglycin, Vglycin, Iglycin, Dglycin, and aM1, exhibit excellent regulatory activities on glucose and lipid metabolism at the cellular and animal levels. Mechanistically, ICK peptides promote glucose utilization by muscle and liver through activation of IR/AKT signaling pathway, which also improves insulin resistance. They can repair the damaged pancrease through activation of PI3K/AKT/Erk signaling pathway, thus lowering blood glucose. The biostability and hypoglycemic efficacy of the ICK peptides meet the requirements for commercialization of oral drugs, and in theory, they can be developed into natural oral anti-diabetes peptide drugs. In this review, the structural properties, activity and mechanism of ICK pattern peptides in regulating glucose and lipid metabolism were summaried, which provided a reference for the development of new oral peptides for diabetes.

Purpose:
The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations.
Methods:
This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits.
Results:
Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01).
Conclusion
Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.
