BACKGROUND: Changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels may not fully translate into patient-reported health status in patients with heart failure (HF). We aimed to evaluate the correlation between NT-proBNP levels and patient-reported health status changes at one month after discharge of patients, and their associations with risk of death and rehospitalization in patients with acute HF. METHODS: We used data from the China Patient-centered Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (PEACE 5p-HF Study). Patient-reported health status was measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Patients who were hospitalized for HF and completed the KCCQ-12 and NT-proBNP tests before and one month after discharge were eligible in our study. We stratified patients into different groups based on NT-proBNP levels (i.e., improved, stable, and deteriorated) and KCCQ-12 scores (i.e., not deteriorated and deteriorated). We also examined the associations of the joint NT-proBNP and KCCQ-12 change with the risk of one-year and four-year clinical outcomes. RESULTS: A total of 2461 patients were included in the analysis. The mean age was 64.06 ± 13.51 years, and 36.37% (895/2461) of the study population were female. Among patients with improved NT-proBNP levels, 115 (10.95%) patients had deteriorated KCCQ-12 scores. The correlation between the change in the KCCQ-12 score and NT-proBNP level was weak ( r2 = 0.002, P = 0.013). Stratification by changes in the KCCQ-12 score revealed subgroups with distinctive risks, such that patients with deteriorated KCCQ-12 scores in any of the NT-proBNP change groups exhibited an increased risk of one-year all-cause death than participants with not deteriorated KCCQ-12 scores in any of the NT-proBNP change groups. Patients with improved NT-proBNP levels and deteriorated KCCQ-12 scores presented greater risks of one-year all-cause death (hazard ratio [HR]: 2.45, 95% confidence interval [CI]: 1.34-4.48) than patients with stable NT-proBNP levels and not deteriorated KCCQ-12 scores (HR [95% CI], 1.77 [1.25-2.53]). CONCLUSIONS: A discrepancy between changes in NT-proBNP levels and KCCQ-12 scores was common. The change in NT-proBNP levels was not sufficient to characterize critical aspects related to HF during one month after discharge of patients. Changes in the KCCQ-12 score exhibit complementary information to NT-proBNP levels for the prediction of clinical outcomes in patients with acute HF.

Lung cancer is one of the most common and deadliest cancers globally, with its incidence and mortality rates rising each year. Therefore, finding new, safe, and effective alternative therapies poses a significant research challenge in this field. Programmed cell death refers to the process by which cells actively self-destruct in response to specific stimuli, regulated by genetic mechanisms. Modern research indicates that dysregulation of programmed cell death is widespread in the occurrence and progression of lung cancer, allowing cancer cells to evade death while continuing to proliferate and metastasize. Thus, inducing the death of lung cancer cells can be considered a novel therapeutic strategy for treating the disease. In recent years, research on traditional Chinese medicine(TCM) in the field of oncology has gained widespread attention, becoming a focal point. An increasing number of studies have demonstrated that TCM can inhibit the progression of lung cancer and exert anti-cancer effects by inducing apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis. This paper provided a comprehensive review of the molecular mechanisms of programmed cell death in lung cancer, along with the potential mechanisms and research advancements related to the regulation of these processes by TCM, so as to establish a theoretical foundation and direction for future basic and clinical research on lung cancer.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Objective: To investigate the distribution of pupil diameter and its association with myopia in school age children, providing ideas into the mechanisms of the role of pupil diameter in the onset and development of myopia. Methods: Adopting a combination of stratified cluster random sampling and convenience sampling method, 3 839 children from six schools in Shandong Province were included in September 2021. Pupil diameters distribution was analyzed by age, sex, and myopic status. Pearson correlation analysis was used to assess the relationship between pupil diameter and cycloplegic spherical equivalent (SE), as well as axial length (AL) and other variables. Propensity score matching (PSM) was applied to match myopic and non myopic children at a 1∶1 ratio based on age and sex. A generalized linear model (GLM) was constructed with pupil diameter as the dependent variable to identify independent factors influencing pupil size and its association with myopia. Results: The mean pupil diameter of school age children was (5.77±0.80)mm. Pupil diameter exhibited a significant increasing trend with age ( F =49.34， P trend ＜ 0.01). Myopic children had a significantly larger mean pupil diameter [(6.10±0.73)mm] compared to non myopic children [(5.62±0.79)mm] with a statistically significant difference( t=18.10, P <0.01). Multivariable GLM analysis, adjusted for age, amplitude of accommodation, and uncorrected visual acuity, revealed a negative correlation between pupil diameter and cycloplegic SE (before PSM: β =-0.089, after PSM: β =-0.063, both P ＜0.01). Conclusions Myopic school age children exhibite larger pupil diameters than their non myopic counterparts. Pupil diameter may serve as a potential indicator for monitoring myopia development in school age children.

Objective: To understand the characteristics of injury cases in Longhua District, Shenzhen City, Guangdong Province from 2021 to 2024, so as to provide the evidence for the development of injury prevention and control measures. Methods: The data of injury cases in the first visit due to injury in the sentinel hospitals of Longhua District from 2021 to 2024 were collected from the Shenzhen Injury Surveillance System. The time, cause, place, activity, intention, nature, position, severity, and outcome of injury were described. Results: From 2021 to 2024, a total of 167 524 injury cases were reported in Longhua District, with a male-to-female ratio of 1.89∶1. The incidence of injuries was higher in cases aged 30-<45 years (49 957 cases, 29.82%). Injuries mainly occurred from July to August (31 272 cases, 18.67%). The main cause of injury was falls (52 048 cases, 31.07%). Injuries mainly occurred at home (64 110 cases, 38.27%). Leisure activities were the main activities when injuries occurred (79 008 cases, 47.16%). Most of the injuries were unintentional (159 173 cases, 95.02%). The main type of injury was contusion/abrasion (71 900 cases, 42.92%). The main injury site was upper limb (64 247 cases, 38.35%). Most injuries were mild (131 369 cases, 78.42%). The main injury outcome was discharge after treatment, 160 882 cases (96.04%). The second cause of male injury was blunt force injury (30 140 cases, 27.49%), and the second cause of female injury was animal injury (14 648 cases, 25.31%). Fall was the leading cause of injury in people aged 0-<15 years and ≥65 years, and blunt force injury was the leading cause of injury in people aged 15-<65 years. The second place for male injuries was industrial and construction places (23 722 cases, 21.64%), and for female injuries was school/public places (9 644 cases, 16.66%). The first place for injuries in people aged 45-<65 years was in industrial and construction places. The proportions of fractures, moderate injuries, and hospitalizations increased with age (all P<0.05). Conclusions The main injury cases in Longhua District were males and people aged 30-<45 years. July and August were a period of high risk for injuries. People aged 0-<15 years and ≥65 years were the high-risk groups of falls. More attention should be paid to the fracture risk in the elderly.

Neuraminidase(NA),a glycoprotein on the surface of the influenza virus,plays a crucial role in viral escape and serves as a stable target for drug candidates.Monoclonal antibodies targeting the NA active site can bind to multiple influenza virus subtypes and inhibit the spread of influenza virus through various mechanisms,such as neutralizing,mediating antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotox-icity.In vivo experiments have shown that human monoclonal antibodies targeting the influenza virus NA can ef-fectively exert preventive and therapeutic effects,rescuing mice infected with lethal doses and reducing viral ti-ters in lungs of mice.This article provides a review of the currently reported human monoclonal antibodies targe-ting NA of Influenza A and Influenza B viruses,providing new ideas and prospects for the subsequent development of anti-influenza drugs.

OBJECTIVE To investigate the incidence of hospital-associated infections among the children with acute leukemia and analyze the economic burden so as to provide scientific bases for formulating the hospital infec-tion management strategies.METHODS A total of 140 children with acute leukemia who were hospitalized in pedi-atric hematology department of the First Affiliated Hospital of Shandong First Medical University and underwent hematopoietic stem cell transplantation from Jan.1,2018 to Jun.30,2024 were recruited as the research subjects.The clinical data,incidence of infections and cost data were collected.The infection group and the non-infection group were matched in a 1∶1 ratio by propensity score matching method.The length of hospital stay and costs of medical items were compared between the infection group and the non-infection group.The economic burden due to the hospital-associated infections was estimated.RESULTS Of the 140 children,59 had hospital-as-sociated infections,with the incidence of infections 42.14％.A total of 125 children who conformed to the inclu-sion and exclusion criteria were included in the study,among whom 53 pairs were matched successfully by propen-sity score matching method.The median hospitalization cost was 230,125.79 yuan in the infection group after the matching,189,880.90 yuan in the non-infection group,and there was significant difference between the two groups(Z=-2.038,P=0.042).The direct economic burden due to the hospital-associated infections in the chil-dren with acute leukemia was 40,244.89 yuan.The median costs of western medicine,self-pay and antibiotics were increased most remarkably among all the costs of medical items(all P＜0.05).CONCLUSION The targeted surveillance of hospital-associated infections and early warning of suspected cases are the major strategies to reduce the incidence of infections and relieve the economic burden.

Objective To investigate the underlying mechanisms of the effect of Fufang Changtai Decoction(FFCT)in inhibiting colorectal cancer(CRC)through the ferroptosis pathway using network pharmacology combined with experimental validation.Methods The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and Swiss Target Prediction databases were employed for the systematic screening of potent active ingredients and therapeutic targets of FFCT.In addition,the identification of CRC-associated genes and ferroptosis-related genes(FRGs)was accomplished using the Gene Cards and FerrDb databases,respectively.Venn diagrams,coupled with Cytoscape software,facilitated the comprehensive analysis of key FRGs involved in FFCT's intervention in CRC by mapping the TCM compound-therapeutic target network.Transmission electron microscopy was used to examine the mitochondrial ultrastructure of SW480 and HCT116,2 Human CRC cell lines,after treatment with FFCT-containing serum.Intracellular reactive oxygen species(ROS)levels were measured using a ROS detection kit.To assess the role of ferroptosis,ferroptosis inhibitor liproxstatin-1(Lip-1)was co-administered with FFCT-containing serum.The effects on cancer cell viability and proliferation were evaluated using CCK-8 and colony formation assays.Key molecular targets involved in the regulatory effects of FFCT on the expression of FRGs were further analyzed using PCR Array and Western blot.The findings were then validated with human CRC tissue microarrays.Results A total of 103 active ingredients of FFCT,739 therapeutic targets,9 101 disease-related genes,and 564 FRGs were identified.Venn diagram analysis identified 81 FRGs associated with FFCT intervention.Network analysis revealed that NQO1,TP53,and PTGS2 served as hub nodes in the regulatory network.Findings from the in vitro experiments showed that FFCT induced ferroptosis changes,including mitochondrial condensation,membrane thickening,and cristae reduction,in SW480 and HCT116 cells.FFCT treatment significantly increased intracellular ROS levels in a dose-dependent manner(P<0.05)and reduced cancer cell viability and proliferative capacity(P<0.01).These inhibitory effects were partially reversed by Lip-1,suggesting that FFCT's antitumor activity was closely associated with the ferroptosis pathway.PCR Array and Western blot analyses further confirmed that FFCT significantly downregulated NQO1 mRNA and protein expression in cancer cells(P<0.001),which was consistent with network pharmacology predictions.Immunofluorescence analysis of clinical CRC tissue microarrays revealed that NQO1 expression was significantly higher in tumor tissues than in adjacent non-tumor tissues(P<0.001).Conclusion FFCT may induce intracellular ferroptosis by downregulating the oncogenic gene NQO1,thereby exerting anti-CRC effects.

Objective:To investigate the influencing factors of adverse reactions of reconstructive flaps after postoperative precision radiation therapy for head and neck tumors.Methods:Medical records of 46 patients who underwent radiotherapy after flap reconstruction for head and neck tumors in the Affiliated Hospital of Inner Mongolia Medical University between January 2016 and October 2022 were retrospectively analyzed. The overall survival (OS), local regional control (LRC) and dosimetric parameters after radiotherapy were analyzed. The adverse reactions mainly including radiation dermatitis and flap necrosis at 3 and 6 months after radiotherapy, flap atrophy, flap fibrosis, dysphagia and chewing dysfunction at 12 and 24 months after radiotherapy were recorded. Adverse reactions were graded using the common terminology criteria for adverse events (CTCAE) version 5.0. Quantitative data were analyzed by one-way analysis of variance or rank-sum test. Qualitative data were analyzed by chi-square test or Fisher's exact test. Multivariate analysis of influencing factors of adverse reactions was performed using binary logistic stepwise regression.Results:All 46 patients were aged 57.6 years on average. The median follow-up time was 65 months (12-100 months). After the follow-up, 22 patients died, 6 recurred, and 7 had distant metastases. The 5-year OS rate was 48% and 5-year LRC rate was 69%. The incidence of radiation dermatitis was decreased over time after the end of radiotherapy: 80% (37/46) and 65% (30/46) at 3 months and 6 months after radiotherapy, respectively. The incidence of grade 3 radiation dermatitis was 11% (5/46) and 0 at 3 and 6 months after radiotherapy, respectively. The incidence of grade 2 flap necrosis was 4% (2/46) at 3 months after radiotherapy. At 12 months after radiotherapy, the incidence of flap atrophy and fibrosis was 83% (38/46) and 67% (31/46) , and the incidence of grade 3 flap atrophy and fibrosis was equally 4% (2/46) , respectively. All patients had dysphagia and chewing dysfunction at 12 months after radiotherapy. At 24 months after radiotherapy, 83% (38/46) and 61% (28/46) of patients still had dysphagia and chewing dysfunction. Multivariate regression analysis showed that irradiated flap volume, total radiotherapy dose, pharyngeal constrictor D mean and pharyngeal constrictor V 60 Gy, the interval between surgery and radiotherapy, gender and age were the independent influencing factors of adverse reactions of reconstructive flaps after precision radiation therapy for head and neck tumors. Conclusions:For patients undergoing flap reconstruction for head and neck tumors, under the premise of ensuring tumor control, the dose to normal tissue and flap blood supply area should be strictly limited, the irradiated volume should be reduced, and the interval between surgery and radiotherapy should be shortened (≤6 weeks) to reduce the risk of adverse reactions. Hypo-fractionated radiotherapy plan should be formulated or the total radiotherapy dose should be appropriately adjusted for elderly patients to reduce long-term complications.

Objective To investigate the relationship between lead exposure and the clinical heterogeneity of amyotrophic lateral sclerosis(ALS).Methods Baseline data were collected from 49 ALS patients hospitalized at the PLA General Hospital.Blood metal levels(copper,zinc,calcium,magnesium,iron,lead)were measured by graphite furnace atomic absorption spectrometry.The Revised ALS Functional Rating Scale(ALSFRS-R)was used to assess the severity of motor function impairment.Patients were grouped by site of onset and ALSFRS-R score,then blood metal levels were compared between two groups.General linear regression,ROC curves and Logistic regression models were applied to analyze the correlation between blood lead levels and disease severity to identify risk factors affecting motor function in ALS patients,and analyze its predictive value.Results The differences of blood metal levels between bulbar onset patients and non-bulbar onset patients were no statistical significance(all P＞0.05).Blood lead levels were significantly lower in the high ALSFRS-R score group than in the low ALSFRS-R score group,and the difference was significant(P=0.02).Blood lead levels were negatively correlated with ALSFRS-R scores in ALS patients(Y=-0.1267X+45.86,R2=0.08937,P=0.04).The area under the ROC curve was 0.70,indicating that blood lead had predictive value for ALS severity.The Logistic regression model demonstrated that elevated blood lead level was an independent risk factor for the severity of ALS disease(OR=1.107,95％CI:1.006-1.219,P=0.04).Conclusions Blood lead levels in ALS patients correlated with disease severity and exhibited predictive utility.Elevated blood lead was an independent risk factor for the severity of motor function impairment in ALS.
