Atherosclerosis （AS） is the main pathological basis of cardiovascular diseases and seriously threatens human quality of life. Its prevention and treatment urgently need breakthroughs. The inflammatory response， which runs through the physiological and pathological evolution process of AS， is one of the important mechanisms for AS occurrence. Currently， the treatment methods for AS in Western medicine are relatively mature. However， they have adverse reactions such as abnormal liver and kidney function， drug tolerance， target vessel restenosis， and stent thrombosis， which remain the key bottleneck restricting clinical efficacy. Traditional Chinese medicine （TCM）， characterized by multiple components， multiple targets， and multi-pathway synergy， shows unique clinical application potential and efficacy advantages in the intervention of AS. This article reviewed the research progress of TCM in intervening in AS by regulating inflammatory-related signaling pathways， such as nuclear factor-κB （NF-κB）， Toll-like receptors （TLRs）， mitogen-activated protein kinase （MAPK）， and Janus kinase/signal transducer and activator of transcription （JAK/STAT）， in the past five years. It summarized the combined mechanism of action of TCM monomers， TCM pairs， and compound preparations in inhibiting the inflammatory cascade reaction through multiple targets， regulating lipid metabolism disorders， and improving vascular endothelial dysfunction and the imbalance of the microenvironment. It deepened the research on the molecular mechanism of TCM in anti-AS， so as to provide a scientific basis for the clinical transformation application and related theoretical research of TCM in anti-AS.

Background Lead smelting workers are exposed to mixed heavy metals such as lead (Pb) and cadmium (Cd). However, the specific associations and molecular mechanisms by which their combined exposure induces genetic damage remain unclear. Objective To clarify the association between combined Pb-Cd exposure and genetic damage and to explore the possible biological mechanisms through occupational epidemiological investigations and animal experiments. Methods (1) Population study: A cross-sectional study was conducted on 374 lead smelting workers in northern China. Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect urinary levels of 8 metals including Pb and Cd, and graphite furnace atomic absorption spectroscopy (GFAAS) was used to quantify blood levels of Pb and Cd. The cytokinesis-block micronucleus assay (CBMN) was used to assess genetic damage. Poisson regression was used to analyze the association between metal exposure and micronucleus rates. (2) In vivo experiment: Thirty SD rats were randomly assigned to five groups: control (pure water), Pb (300 mg·L⁻¹ lead acetate), Cd (50 mg·L⁻¹ cadmium chloride), combined exposure (Pb + Cd), and resveratrol intervention (Pb + Cd + 50 mg·L⁻¹ resveratrol). After 8 weeks of ad libitum drinking water exposure, liver pathology, oxidative stress indicators [reactive oxygen species (ROS), reduced glutathione (GSH), oxidized glutathione (GSSG), malondialdehyde (MDA), catalase (CAT), and superoxide dismutase (SOD)], genetic damage (Comet assay and γ-H2AX) were evaluated. Furthermore, cell cycle distribution, apoptosis rates, and mRNA expression of DNA damage response (DDR), DNA repair, and apoptosis-related genes were measured. Results (1) The geometric mean (GM, 95%CI) of urinary Pb and Cd were 14.69 (13.14, 16.51) µg·L⁻¹ and 2.11 (1.90, 2.33) µg·L⁻¹, respectively; the blood Pb and Cd levels were 117.10 (105.59, 129.87) µg·L⁻¹ and 4.55 (4.23, 4.89) µg·L⁻¹, respectively among the 374 workers. The mean micronucleus rate was (1.64±0.081) ‰, with significantly higher rates in males (1.65±0.083) ‰ than females (1.53±0.334) ‰ (U=4.166, P=0.041). All Pb and Cd biomarkers were positively correlated with micronucleus rate (FR>1, P<0.05), with a significant interaction effect observed between Pb and Cd (FR>1, P<0.05). (2) In rats, co-exposure to Pb and Cd caused liver tissue damage and inflammatory infiltration. Significant increases were observed in lymphocyte ROS; GSSG and MDA in lung tissue increased, while GSH and CAT activity decreased. Comet assay indicators and γ-H2AX levels were significantly elevated. Co-exposure induced S-phase arrest and increased apoptosis. mRNA levels of DDR (ATM, ATR, Chk2, and P53) and pro-apoptotic genes (Bax and Caspase-3) were upregulated, while the anti-apoptotic gene Bcl-2 and DNA repair genes (BRCA1, BRCA2, RAD51, RAD52, and CtIP) were downregulated. Two-way ANOVA confirmed synergistic effects on GSSG, Comet assay indicators, and ATR/Chk2 mRNA expression. Conclusion Occupational co-exposure to Pb and Cd synergistically induces genetic damage. This damage is mediated by oxidative stress and DNA damage, which activates the DDR pathway and inhibits the expression of DNA repair genes, ultimately leading to cell cycle arrest and apoptosis.

Objective: To investigate the status and influencing factors of influenza vaccination among the elderly, so as to provide insights into improving the strategies for influenza vaccination among the elderly. Methods: Elderly people aged 60 years and above were recruited from one community each in five sub-districts of Shihezi City, Xinjiang Uygur Autonomous Region using a random sampling method. Demographic information, knowledge about influenza and influenza vaccines, vaccine literacy and influenza vaccination status in the past year were collected through questionnaire surveys. Factors affecting influenza vaccination among the elderly were analyzed using a multivariable logistic regression model. Results: Totally 1 121 valid questionnaires were recovered, with an effective recovery rate of 95.08%. There were 417 males (37.20%) and 704 females (62.80%). The majority were aged 60-<81 years, accounting for 80.37% (901 individuals). The awareness of knowledge about influenza and influenza vaccines was 78.86%. Low vaccine literacy was observed in 786 individuals, representing 70.12%. The influenza vaccination rate was 20.96%. Multivariable logistic regression analysis showed that age (71-<81 years, OR=1.607, 95%CI: 1.041-2.479; ≥81 years, OR=1.719, 95%CI: 1.040-2.842), educational level (middle school/technical secondary school, OR=0.616, 95%CI: 0.416-0.911), medical expense payment (employee medical insurance, OR=6.531, 95%CI: 2.030-21.010; resident medical insurance, OR=3.385, 95%CI: 1.095-10.466; public expense, OR=4.828, 95%CI: 1.700-13.712), vaccination willingness (yes, OR=6.237, 95%CI: 3.277-11.871), influenza vaccination history (yes, OR=14.600, 95%CI: 8.733-24.408) and vaccine literacy (medium and above, OR=2.412, 95%CI: 1.636-3.555) were associated with influenza vaccination among the elderly. Conclusion The influenza vaccination rate among the elderly was relatively low, and was mainly affected by age, educational level, medical expense payment, vaccination willingness, influenza vaccination history and vaccine literacy.

Objective:To investigate the effects of Juglone on the apoptosis of osteosarcoma(OS)cells(U2OS and MG63 cells)through the cysteinyl aspartate specific proteinase-3(Caspase-3)/gasdermin E(GSDME)-mediated pyroptosis pathway.Methods:The U2OS and MG63 cells were cultured in vitro and divided into control group,different concentrations(5,10 and 20 μmol·L-1)of Juglone groups and Caspase-3 inhibitor Z-DEVD-FMK group(10 μmol·L-1 Juglone+30 μmol·L-1 Z-DEVD-FMK).The survival rates of cells in various groups were assessed by cell counting kit-8(CCK-8)assay,and the apoptotic rates were detected by flow cytometry.Lactate dehydrogenase(LDH)release assay was used to measure the release rates of LDH from the cells.Western blotting method was used to detect the expression levels of apoptosis-related proteins including B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),cleaved-Caspase-3 and poly(ADP-ribose)polymerase(PARP)and pyroptosis-related proteins including GSDME full form(GSDME-F)and GSDME N-terminal(GSDME-N).The levels of interleukin-1β(IL-1β)and interleukin-18(IL-18)in the cell supernataut in various groups were measured by enzyme-linked immunosorbent assay(ELISA)method.Results:Compared with control group,the survival rates of cells in 5,10,and 20 μmol·L-1Juglone groups were significantly decreased(P＜0.05 or P＜0.01),and the 50％inhibitory concentration(IC50)values of U2OS cells and MG63 cells were 8.4 and 10.2 μmol·L-1,respectively.Compared with control group,the apoptotic rates and LDH release rates of U2OS and MG63 cells in 5 and 10 μmol·L-1Juglone groups were significantly increased(P＜0.05 or P＜0.01).Compared with control group,the expression levels of Bax,cleaved-Caspase-3,and cleaved-PARP proteins in 5 and 10 μmol·L-1 Juglone groups were significantly increased(P＜0.01),while the expression levels of Bcl-2 protein were significantly decreased(P＜0.01).Compared with control group,the levels of IL-1β and IL-18 in cell supernatant in 5 and 10 μmol·L-1Juglone groups were increased(P＜0.01).Compared with control group,the expression levels of cleaved-Caspase-3 and GSDME-N proteins in 5 and 10 μmol·L-1 Juglone groups were significantly increased(P＜0.01),while there was no difference in the expression level of GSDME-F protein(P＞0.05).Compared with 10 μmol·L-1 Juglone group,the expression levels of cleaved-Caspase-3 and GSDME-N in Z-DEVD-FMK group were significantly decreased(P＜0.01),while there was no difference in the expression level of GSDME-F protein(P＞0.05).Conclusion:Juglone can induce the apoptosis of U2OS and MG63 cells and cause the Caspase-3/GSDME-mediated pyroptosis.

Objective:Using surface-based morphometry (SBM), this study longitudinally tracks dynamic changes in whole-brain cortical morphological parameters in depression patients before and after vortioxetine treatment. Through three-dimensional topological characterization, we investigate the neuroanatomical correlations between cortical structural reorganization and improvements in affective symptoms and cognitive functions.Methods:Prospectively collected clinical data from 22 outpatients with depression (10 males and 12 females, aged 18-50 years, mean age 28.1±9.1) who attended Beijing Huilongguan Hospital clinic from October 2018 to December 2019. An age-matched healthy control group ( n=21; 10 males and 11 females, aged 22-44 years, mean age 30.8±6.6) was recruited concurrently. The Hamilton Rating Scale for Anxiety (HAMA), the 17-item Hamilton Depression Scale (HAMD 17), and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used to evaluate the severity of depressive symptoms and cognitive function in patients. Structural magnetic resonance imaging (sMRI) was performed to assess brain structural indices in depression patients before and after vortioxetine treatment, as well as in healthy controls. Whole-brain cortical structure measurements were calculated for all subjects using CAT12 software. Paired-sample t-tests were used to compare changes in cortical structure and clinical scale scores in depression patients before and after treatment, and two-sample t-tests were conducted to compare whole-brain cortical structure differences between patients (pre-and post-treatment) and healthy controls. Multiple regression analysis in SPM 12 was applied to examine the correlation between post-treatment cortical structural indices and clinical and cognitive scale scores in patients. Spearman correlation analysis was used to evaluate the correlation between changes in whole-brain cortical structure and cognitive function before and after vortioxetine treatment. Results:After vortioxetine treatment, patients with depression exhibited significant reductions in HAMA and HAMD 17 scores, along with significant increases in immediate memory, delayed memory, and total RBANS scores, with statistically significant differences observed ( t=8.43, 12.28, -4.71, -2.41, -3.86 respectively; all P<0.05), while there were no significant changes in visual span, language function, or attention ( P>0.05). Compared to healthy controls, depression patients showed a significantly reduced gyrification index in the right insula/superior temporal gyrus before treatment (28.74±1.20 vs 27.44±1.17; t=4.47, P<0.001), but no significant differences in whole-brain cortical structure were observed before and after treatment or between post-treatment patients and healthy controls ( P>0.05). Correlation analysis indicated that fractal dimension was negatively correlated with HAMA and HAMD 17 scores after treatment, while gyrification index was positively correlated with HAMD 17 ( rpartial=-0.79, -0.83, 0.72; P<0.05). Visual span was positively correlated with fractal dimension ( rpartial=0.78) and negatively correlated with gyrification index ( rpartial=-0.73, P<0.05). Sulcal depth was negatively correlated with attention and RBANS total scores ( rpartial=-0.77, -0.75; P<0.05). Additionally, changes in gyrification index in the left fusiform gyrus were positively correlated with changes in attention ( r=0.51), changes in gyrification index in the left posterior cingulate gyrus were positively correlated with changes in immediate memory ( r=0.58), and changes in sulcal depth in the left superior frontal gyrus were negatively correlated with changes in language ability ( r=-0.79) (both P<0.05). Conclusion:Vortioxetine treatment can improve anxiety and depressive symptoms in depression patients, as well as enhance certain cognitive functions, while also affecting cortical structure in the specific cortical area. Changes in cortical structure after vortioxetine treatment are closely related to clinical symptom improvement and cognitive function changes.

Objective:To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation (ECMO) for critically ill children.Methods:This was a retrospective cohort study. Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected. The cases were divided into primary and secondary transport groups by nature of transport. The clinical data, including demographics, ECMO indications, transport distance, pre-transport lab results, prognosis and complications were analyzed. Two independent samples t-test, Wilcoxon test, and χ2 test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport. Results:Among the 222 children transported with ECMO, there were 135 males and 87 females, with an age of 3.0 (0.2, 7.0) years. There were 202 cases in the primary transport group and 20 cases in the secondary transport group. All secondary transport patients had failed attempts at weaning ECMO before transfer. The patients in the secondary transport group were older, had higher rates of surgical cannulation, circulatory support, and pre-ECMO lactate levels compared to the primary transport group (7.0 (2.8, 10.0) vs. 3.0 (0.2, 6.0) years old, 55.0% (11/20) vs. 3.6% (7/202), 80.0% (16/20) vs. 41.6% (84/202), (10±4) vs. (7±6) mmol/L, Z=3.41, χ 2=66.31, 10.99, t=2.24, all P<0.05). In the secondary transport group, the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group (83±33 vs. 82±68, 51.0±1.8 vs. 37.4±10.2, t=2.36, 2.63, respectively; both P<0.05). There were no statistically significant differences between the 2 groups in sex, transport distance, pre-ECMO creatinine, arterial blood gas BE values, and ECMO duration (all P>0.05). No life-threatening complications occurred during the transport in either group. Two patients in the secondary transport group underwent heart transplantation, and 1 patient underwent radiofrequency ablation. The overall survival rate between the 2 groups showed no statistically significant difference (45.0% (9/20) vs. 55.4% (112/202), χ2=1.15, P>0.05). Conclusions:Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport. ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.

Objective:To evaluate the safety and clinical efficacy of enteral nutrition (EN) initiated within 24 h after heart transplantation in pediatric patients.Methods:A retrospective cohort study was conducted. Clinical data from 16 pediatric heart transplant recipients at the Seventh Medical Center of the Chinese People′s Liberation Army General Hospital between October 2022 and October 2024 were collected, including demographics, anthropometric measurements, biochemical markers, cytokine levels, and clinical outcomes. Based on the timing of EN initiation, the patients were divided into EN-initiated within 24 h and EN-initiated after 24 h 2 groups. Demographic data, preoperative extracorporeal membrane oxygenation (ECMO) support, physical examination indicators, laboratory parameters, and cytokine levels were compared between groups using independent samples t-test, Mann-Whitney U test, Fisher′s exact probability test. Results:The cohort comprised 16 patients (10 males and 6 females) with an age of (12.5±1.9) years. The EN-initiated within 24 h group comprised 6 cases, and the EN-initiated after 24 h group comprised 10 cases. No significant difference was observed between the two groups in age, preoperative body mass index Z-score, preoperative ECMO support, physical examination indicators, laboratory parameters (total protein, albumin, hemoglobin), or cytokine levels (all P>0.05). Compared to the EN-initiated after 24 h group, the EN-initiated within 24 h group exhibited a shorter intensive care unit stay ( t=2.65, P<0.05) and shorter mechanical ventilation duration ( t=2.23, P<0.05) than EN-initiated after 24 h group. Total hospitalization length had no significant difference ( P>0.05). At 72 h post-transplant, the EN-initiated within 24 h group had a lower interleukin-12 P70 ( t=2.46, P<0.05) and interferon-γ levels ( t=2.55, P<0.05) than EN-initiated after 24 h group. Prior to discharge, the EN-initiated within 24 h group has a lower mean skinfold thickness ( t=2.49, P<0.05) and lower mid-upper arm circumference ( t=2.36, P<0.05) compared with the EN-initiated after 24 h group. Conclusions:Initiating EN within 24 h postoperatively is safe and feasible in pediatric heart transplant recipients. Early EN may shorten the length of intensive care unit stay and mechanical ventilation while attenuating postoperative release of inflammatory cytokine.

Hypoplastic left heart syndrome is a congenital heart disease characterized by mitral and（or）aortic valve stenosis or atresia，leading to the hypoplasia of the left ventricle，ascending aorta and aortic arch.If not treated in time，most children die within a few weeks after birth.Congenital complete atrioventricular block is a rare congenital cardiac conduction disorder.When combined with severe cardiac malformations，the mortality rate is extremely high.In this case，a 26-year-old pregnant woman with a history of 3 pregnancies and 1 delivery，had a natural conception with monochorionic diamniotic twins. At 22 +5 weeks of gestation，it was first found that one of the twins had hypoplastic left heart syndrome with congenital complete atrioventricular block through fetal echocardiography detection.This situation was extremely rare，and there was a lack of clinical guidelines on how to manage the pregnancy and determine the time of delivery time.In this case，prenatal ultrasound was used to monitor and comprehensively evaluate fetal cardiac function through the cerebroplacental ratio（CPR）combined with the cardiovascular overall performance score（CVPS）.Pregnancy safety management was implemented，and a cesarean section was performed at an elective time.Another healthy fetus did not suffer any adverse effects. This case provides strong evidence for ensuring the safety of healthy fetus and mother in perinatal period.It is also confirmed that CPR and CVPS combined evaluation of fetal cardiac function and pregnancy outcome will be more accurate and comprehensive.This method is simple，accurate，non-invasive，and can be used as an effective method for clinical evaluation of fetal cardiac function.
