Objective:To explore the level of mental health literacy and its relationship with symptoms of de-pression,anxiety,and insomnia in young adults.Methods:A total of 10 273 young adults aged 18-23 in Guang-zhou were selected and assessed with the National Mental Health Literacy Questionnaire,Patient Health Question-naire-9(PHQ-9),General Anxiety Disorder 7-Item Scale(GAD-7)and Insomnia Severity Index(ISI).Results:Totally 1 137(11.1％)participants met the criteria for adequate mental health literacy,2 758(26.8％)participants were with symptoms of depression,1 355(13.2％)with symptoms of anxiety and 4 936(48.0％)experiencing symptoms of insomnia.Logistic regression analyses showed that after adjusting for other factors,substandard mental health literacy was an independent risk factor for symptoms of depression,anxiety and insomnia(OR=2.08,1.93,1.49;95％CI:1.74-2.48,1.52-2.46,1.31-1.70).Conclusion:The level of mental health literacy in young a-dults is insufficient,and the lack of mental health literacy is significantly associated with the symptoms of depres-sion,anxiety and insomnia.

Coronavirus disease 2019 (COVID-19) is an acute infectious respiratory disease that has been prevalent since December 2019. Chinese medicine (CM) has demonstrated its unique advantages in the fight against COVID-19 in the areas of disease prevention, improvement of clinical symptoms, and control of disease progression. This review summarized the relevant material components of CM in the treatment of COVID-19 by searching the relevant literature and reports on CM in the treatment of COVID-19 and combining with the physiological and pathological characteristics of the novel coronavirus. On the basis of sorting out experimental methods in vivo and in vitro, the mechanism of herb action was further clarified in terms of inhibiting virus invasion and replication and improving related complications. The aim of the article is to explore the strengths and characteristics of CM in the treatment of COVID-19, and to provide a basis for the research and scientific, standardized treatment of COVID-19 with CM.

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.

Age-related macular degeneration (AMD) represents a predominant cause of blindness among older adults, with limited therapeutic options currently available. Oxidative stress, inflammation, and retinal pigment epithelium injury are recognized as key contributors to the pathogenesis of AMD. Regulated cell death plays a pivotal role in mediating cellular responses to stress, maintaining tissue homeostasis, and contributing to disease progression. Recent research has elucidated several regulated cell death pathways-such as apoptosis, ferroptosis, pyroptosis, necroptosis, and autophagy-that may contribute to the progression of AMD owing to cell death in the retinal pigment epithelium. These discoveries open new avenues for therapeutic interventions in patients with AMD. In this review, we provide a comprehensive summary and analysis of the latest advancements regarding the relationship between regulated cell death and AMD. Moreover, we examined the therapeutic potential of targeting regulated cell death pathways for the treatment and prevention of AMD, highlighting their roles as promising targets for future therapeutic strategies.

OBJECTIVE: This study reports the first imported case of Lassa fever (LF) in China. Laboratory detection and molecular epidemiological analysis of the Lassa virus (LASV) from this case offer valuable insights for the prevention and control of LF. METHODS: Samples of cerebrospinal fluid (CSF), blood, urine, saliva, and environmental materials were collected from the patient and their close contacts for LASV nucleotide detection. Whole-genome sequencing was performed on positive samples to analyze the genetic characteristics of the virus. RESULTS: LASV was detected in the patient's CSF, blood, and urine, while all samples from close contacts and the environment tested negative. The virus belongs to the lineage IV strain and shares the highest homology with strains from Sierra Leone. The variability in the glycoprotein complex (GPC) among different strains ranged from 3.9% to 15.1%, higher than previously reported for the seven known lineages. Amino acid mutation analysis revealed multiple mutations within the GPC immunogenic epitopes, increasing strain diversity and potentially impacting immune response. CONCLUSION The case was confirmed through nucleotide detection, with no evidence of secondary transmission or viral spread. The LASV strain identified belongs to lineage IV, with broader GPC variability than previously reported. Mutations in the immune-related sites of GPC may affect immune responses, necessitating heightened vigilance regarding the virus.

The menopausal age is one of the important menopausal factors, and women of different menopausal ages have different risks of diabetes. This study reviewed the evidence from prospective studies on the association between the age at natural menopause and diabetes risk, both domestically and internationally, and presented its research design and main findings. Advanced menopause, especially premature and early menopause, will increase the risk of diabetes in postmenopausal women. The research on the influence of delayed menopause on the incidence of diabetes is still insufficient. Many factors may modify the association between menopausal age and the risk of diabetes.

Objective:To adapt the Mindful Breastfeeding Scale (MINDF-BFS) into Chinese and assess its reliability and validity among breastfeeding mothers in China.Methods:Following the Beaton cross-cultural adaptation guideline, the original scale was translated, back-translated, discussed by experts, pre-tested, culturally adapted, and revised to develop the Chinese version of the MINDF-BFS. A convenience sampling method was used to select 305 postpartum women from Guangzhou Women and Children's Medical Center, Guangzhou Medical University, who visited between March and June 2024, as the study participants. The reliability and validity of the Chinese version of MINDF-BFS were evaluated.Results:The Chinese version of MINDF-BFS consisted of nine items, with the item-level content validity index ranged from 0.900 to 1.000, and the average scale-level content validity index was 0.990. Exploratory factor analysis extracted one common factor, with a variance contribution of 73.290%. Confirmatory factor analysis showed a good model fit. The Cronbach's α coefficient for the scale was 0.923, the split-half reliability coefficient was 0.915, and the test-retest reliability coefficient was 0.926.Conclusions:The Chinese version of MINDF-BFS has good psychometric properties and is suitable for assessing the mindful breastfeeding levels of Chinese postpartum women.
