BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

OBJECTIVE: To observe the clinical effect and safety of Lu'e Biyan Formula (LBF) combined with loratadine in the treatment of moderate to severe allergic rhinitis (AR) patients with Fei (Lung)-qi deficiency-coldness (FQDC) syndrome. METHODS: From September 2023 to December 2024, moderate to severe AR patients with FQDC syndrome were recruited from the Outpatient Department of Integrated Traditional Chinese and Western Medicine for Pulmonary Diseases Part 1, China-Japan Friendship Hospital. Participants were randomly assigned to a test group and a control group by using a random number table at a ratio of 1:1. Both groups received oral loratadine tablets (10 mg, once daily) for 2 weeks. In addition, the test group received oral LBF (30 mL, twice daily), and the control group received a placebo of LBF. Changes in the Total Nasal Symptom Score (TNSS), Total Non-nasal Symptom Score (TNNSS), Visual Analog Scale (VAS), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and Chinese medicine (CM) syndrome scores before and after treatment were compared between groups. Moreover, the total effective rates and disease recurrence rates were compared. Adverse events (AEs) during the study period were also recorded. RESULTS: Totally 109 participants were recruited, and the full analysis set included 105 cases, 54 in the test group and 51 in the control group. Compared with the pre-treatment values, the scores of sneezing, runny nose, nasal obstruction, nasal itching, TNSS, TNNSS, VAS, RQLQ, and CM syndrome were significantly reduced in both groups at 1 and 2 weeks post-treatment and 12 weeks post-drug withdrawal (P<0.01). After treatment, the aforementioned scores in the test group were all markedly lower than those in the control group (P<0.01). Moreover, the total effective rate in the test group was higher than that in the control group (98.15% vs. 70.59%, P<0.01). After 12 weeks of drug withdrawal, there was no significant difference in the recurrence rate between groups (13.21% vs. 22.22%, P>0.05). No obvious AEs were observed in either group following treatment. CONCLUSIONS The combination of LBF with loratadine can effectively alleviate the symptoms of moderate to severe AR patients with FQDC syndrome, thereby improving their quality of life. This therapy demonstrated both precise effect and high safety. (Trial registration No. ITMCTR2025000589).

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To observe the clinical efficacy of Qigui Tongluo Oral Liquid(a hospital preparation developed by Guangdong Second Traditional Chinese Medicine Hospital and being composed of Astragali Radix,Angelicae Sinensis Radix,Notoginseng Radix et Rhizoma,Paeoniae Radix Rubra,Achyranthis Bidentatae Radix,Spatholobi Caulis,Salviae Miltiorrhizae Radix et Rhizoma,Pheretima,etc.)combined with moxibustion for the treatment of chronic fatigue syndrome(CFS)of qi deficiency and blood stasis type on the basis of qi-collateral theory.Methods A retrospective study was conducted in 60 CFS patients with qi deficiency and blood stasis type.The patients were divided into an observation group and a control group,with 30 patients in each group according to the therapy.The control group was treated with mild moxibustion on Shenque(CV8)point with moxa sticks,and the observation group was treated with Qigui Tongluo Oral Liquid on the basis of treatment for the control group.The course of treatment lasted for 4 weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,Fatigue Scale-14(FS-14)scores,serum immunoglobulin IgA,IgM,IgG levels,and cortisol(COR)level in the two groups were observed before and after the treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the observation group was 96.67%(29/30),and that of the control group was 80.00%(24/30).The intergroup comparison showed that the clinical efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores and FS-14 scores of patients in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the effect on decreasing TCM syndrome scores and FS-14 scores in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the serum IgA and IgG levels of the two groups as well as the serum IgM and COR levels of the observation group were significantly increased compared with those before treatment(P＜0.01),and the effect of the observation group on increasing serum IgA,IgM,IgG,and COR levels was significantly superior to that of the control group(P＜0.05 or P＜0.01).(4)During the treatment,there were no significant adverse reactions occurring in the two groups.Conclusion Healthy-qi deficiency and collateral obstruction contribute to the core pathogenesis of CFS.Based on the TCM qi-collateral theory and following the therapeutic principle of replenishing deficiency and unblocking collaterals,Qigui Tongluo Oral Liquid combined with moxibustion for the treatment of CFS patients with qi deficiency and blood stasis type can achieve certain efficacy.The combined therapy could significantly alleviate the clinical symptoms,improve the immunity level,and regulate the neuro-endocrine-immune(NEI)network of the patients.

Artificial intelligence(AI)has made major strides in ophthalmology in recent years.Yet,its application in resolving children's ocular problems has received limited attention.The automated detection system for retinopathy of pre-maturity has achieved expert-level accuracy in diagnosis.AI has been applied to categorize cataract abnormalities in chil-dren,forecast postoperative complications of cataracts,predict the progression of high myopia,and automatically detect strabismus and refractive error.Additionally,AI has also been utilized in visual development research,segmentation of vas-cular development in children's fundus images,and the synthesis of ophthalmic images.Applying AI technologies in pediat-ric ophthalmology can greatly enhance the accuracy of disease diagnosis and the efficiency of treatment and improve clinical care.This article reviews the application,shortcomings and future development of AI in the diagnosis of retinopathy of pre-maturity,dyslexia in children,pediatric vision screening,amblyopia,strabismus,ametropia,and childhood cataracts.

The prevalence of myopia is substantial in China,significantly impacting children's visual health.Current research indicates that extended screen time and inadequate outdoor activities are pivotal factors contributing to childhood myopia.These risk factors are closely associated with light parameters,including intensity,duration,frequency and spec-trum.Moreover,inappropriate nighttime lighting can disturb children's circadian rhythms and sleep and contribute to myo-pia development.This study reviews clinical research and epidemiological data on screen time,outdoor activities,light properties and circadian rhythms,aiming to offer recommendations and guidance for preventing myopia in children.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

This study aims to investigate the effect of Linggui Zhugan Decoction(LGZGD) on autophagy in the mouse model of chronic heart failure(CHF) induced by myocardial infarction(MI), as well as the regulatory effect of LGZGD on the hypoxia-inducible factor-1α(HIF-1α)/heme oxygenase-1(HO-1) signaling pathway, based on bioinformatics and animal experiments. The active ingredients and corresponding targets of LGZGD were retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Database, and GEO, GeneCards, and DisGeNET were searched for the disease targets. Cytoscape was used to establish a "drug-component-target" network. The protein-protein interaction(PPI) network analysis was performed on STRING. R language was used for Gene Ontology(GO) and Kyoto Encycloperfia of Genes and Genomes(KEGG) enrichment analyses. Molecular docking was adopted to validate the core targets. The mouse model of MI-induced CHF was established by surgical ligation of the left anterior descending coronary artery. The modeled mice were assigned into the sham, model, low-, medium-, and high-dose(2.34, 4.68, and 9.36 g·kg~(-1), respectively) LGZGD, and captopril(3.25 mg·kg~(-1)) groups. After continuous administration for 6 weeks, a Doppler ultrasound imaging system was used to examine the heart function indicators: left ventricular ejection fraction(LVEF), left ventricular fractional shortening(LVFS), left ventricular end-systolic dimension(LVIDs), and left ventricular end-diastolic dimension(LVIDd). The myocardial tissue was stained with hematoxylin-eosin for the observation of morphological changes. The mRNA levels of microtubule-associated protein 1 light chain 3 beta(LC3B), Beclin1, p62, HIF-1α, and HO-1 in the myocardial tissue were determined by RT-qPCR. The protein levels of LC3B, beclin1, p62, autophagy-related protein 5(ATG5), HIF-1α, and HO-1 were determined by Western blot. The results showed that 103 active components of LGZGD, corresponding to 224 targets, were obtained. A total of 3 485 and 6 165 targets related to MI and CHF, respectively, were retrieved. The GSE16499 dataset obtained 3 263 differentially expressed genes. There were 31 common targets. The top 3 core active components were quercetin, naringenin, and 1-methoxyphaseollidin. The topology analysis results showed that the core targets were MAPK3, HMOX1(HO-1), MYC, ADRB2, PPARD, and HIF1A(HIF-1α). The molecular docking results showed strong binding between the core targets and the main active components of LGZGD. LGZGD significantly improved the heart function and alleviated the pathological changes in the myocardial tissue of mice. Western blot and RT-qPCR results showed that the HIF-1α/HO-1 signaling pathway and autophagy were activated in the model group. LGZGD up-regulated the levels of LC3B, Beclin1, ATG5, HIF-1α, and HO-1 while down-regulating the mRNA and protein levels of p62. In summary, LGZGD can enhance autophagy and improve the heart function in the mouse model of CHF after MI by upregulating the HIF-1α/HO-1 signaling pathway.

Wound healing is a slow and complex biological process, including inflammatory reaction, cell proliferation, cell differentiation, cell migration, angiogenesis, extracellular matrix deposition, tissue remodeling, and so on. Wnt signaling pathway can be divided into classical pathway and non-classical pathway. Wnt classical pathway, also known as Wnt/β-catenin signaling pathway, plays an important role in cell differentiation, cell migration, and maintenance of tissue homeostasis. Many inflammatory factors and growth factors are involved in the upstream regulation of this pathway. The activation of Wnt/β-catenin signaling pathway plays an important role in the occurrence, development, regeneration, repair and related treatment of skin wounds. This article review the relationship between Wnt/β-catenin signaling pathway and wound healing, meanwhile summarizes its effects on important processes of wound healing, such as inflammation, cell proliferation, angiogenesis, hair follicle regeneration, and skin fibrosis, as well as the role of inhibitors of Wnt signaling pathway in wound healing.
