Objective To explore the correlation between serum ferritin and the risk of metabolic syndrome, and to provide evidence for the prevention and control of metabolic syndrome. Methods Data was from the Jiang'an District survey data of the Chinese Resident Nutrition and Health Monitoring Project in 2022. A total of 399 adult residents were selected as the study subjects and the investigation was performed by questionnaire, physical examination and biochemical testing. Statistical analysis was conducted by SAS 9.4 software, and the association between serum ferritin and metabolic syndrome was analyzed by using multivariate logistic regression. Results The prevalence of metabolic syndrome in the study population was 43.61%, and 39.04% after standrdization. With the increase of serum ferritin levels, the prevalence of metabolic syndrome gradually increased (P<0.05). Serum ferritin was positively correlated with WC, DBP, TG, FPG, hsCRP, and HbA1c, while negatively correlated with HDL-C (P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, female serum ferritin was positively correlated with the prevalence of metabolic syndrome (OR=3.59，95% CI：1.72-7.46); however, male serum ferritin level was not correlated with the prevalence of metabolic syndrome (OR=2.02，95% CI：0.76-3.40). Conclusion The prevalence of metabolic syndrome among residents in Jiang'an District is relatively high. Serum ferritin is associated with various components of metabolic syndrome, and the high serum ferritin level in women is associated with a higher risk of metabolic syndrome.

Rosacea is a chronic facial inflammatory skin disease. It has been proved that heredity, immunity, neurovascular disorders, microorganisms, skin barrier damage and ultraviolet rays are closely related to the occurrence of rosacea. However, the exact pathogenesis of rosacea has not been fully elucidated. This review summarizes recent advances in the pathogenesis of rosacea in the past 5 years.

Objective To preliminarily investigate the anti-tumor effects of phytosphingosine(PHS)and the involvement of inducing apoptosis of leukemia cells.Methods Cellular model of leukemia was established in leukemia cell lines K562 and SUP-B15.CCK-8 assay and EdU assay were used to measure the viability and DNA synthesis of K562 and SUP-B15 cells.RNA-seq was carried out to verify the differentially expressed genes(DEGs)after PHS treatment.Gene Ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were applied to analyze the involved functions and signaling pathways.Comparative Toxicogenomics Database(CTD)and Discovery Studio software were employed to predict the underlying targets of PHS and molecular docking.Cell apoptosis was detected by flow cytometry,mitochondrial membrane potential was evaluated by JC-1 probe,and protein expression of key molecules was validated by Western blotting.Results PHS inhibited the proliferation of K562 and SUP-B15 cells in a time-and dose-dependent manner.The half-maximal inhibitory concentration(IC50)of K562 cells was 17.67 and 12.52 pmol/L for 24 and 48 h,respectively,and the IC50 value of SUP-B15 cells was 17.58 and 14.86 μmol/L for 24 and 48 h,respectively.PHS treatment at a dose of 20 μmol/L for 48 h resulted in significant inhibition of DNA synthesis.GO enrichment analysis of the K562 cells showed that PHS might be involved in positive regulation of apoptotic process,plasma membrane and its integral components,and protein kinase binding and activity.Reverse predictive analysis showed that BCL-2 protein was the most likely target of PHS.PHS significantly increased the apoptotic rate of leukemia cells(P＜0.05)in a dose-dependent manner,reduced the mitochondrial membrane potential,and down-regulated BCL-2 level(P＜0.05)and up-regulated the levels of Cleaved caspase-3 and Cleaved caspase-9(P＜0.05).Conclusion PHS may inhibit the proliferation of leukemia cells by inducing mitochondria-dependent apoptosis,possibly through PHS and BCL-2 interaction.

BackgroundChronic insomnia is characterized by a prolonged and recurrent course. The efficacy of repeated transcranial magnetic stimulation （rTMS） as a physical therapy method to improve sleep quality remains inadequately supported by evidence， particularly regarding its relationship with personality traits. ObjectiveTo explore the efficacy and influencing factors of rTMS in the treatment of chronic insomnia， and to provide insights into its therapeutic potential. MethodA total of 46 patients who met the diagnostic criteria for chronic insomnia according to the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， and were treated at the Third Hospital of Mianyang from September 2022 to September 2023 were selected. Prior to treatment， participants underwent assessments using the Eysenck Personality Questionnaire （EPQ）， Hamilton Depression Scale-17 item （HAMD-17） and Hamilton Anxiety Scale （HAMA）. The Pittsburgh Sleep Quality Index （PSQI） was used to assess sleep quality before treatment， at the end of the second week of treatment and one week post-treatment. ResultsAt the end of the second week of treatment， patients exhibited significantly improved total PSQI score and subscale scores related to subjective sleep quality， sleep latency， sleep duration， sleep efficiency， sleep disturbance and daytime dysfunction （t=4.755~13.361， P<0.01）， with 24 cases （54.35%） showing effective treatment outcomes. Multiple linear regression analysis showed that introverted and extroverted personality traits contributed significantly to the regression equation （B=0.317， P<0.01）， explaining 29.90% of the total variation （R²=0.299）. ConclusionrTMS treatment may effectively improve the sleep quality of patients with chronic insomnia， with its therapeutic effect appearing to associated with introverted and extroverted personality traits. ［Funded by National Natural Science Project of China （number， 82372080）］

Objective: To investigate the epidemilogical characteristics of pulmonary tuberculosis in Huzhou City, Zhejiang Province from 2014 to 2023, so as to provide the basis for formulating prevention and control measures for the construction of "TB-free city". Methods: The data of pulmonary tuberculosis cases in Huzhou City from 2014 to 2023 was collected through the Infectious Disease Reporting Management System of Chinese Disease Prevention and Control Information System. The onset time, region, and population distribution characteristics of the cases were described. Results: A total of 11 598 cases of pulmonary tuberculosis were reported in Huzhou City from 2014 to 2023, with an average annual incidence of 37.42/105. The reported incidence decreased from 47.50/105 in 2014 to 28.36/105 in 2023 (P<0.05), with an annual decline rate of 5.57%. There were 6 304 etiological positive cases, accounting for 54.35%. The peak season for pulmonary tuberculosis cases was from March to September, with the highest seasonal ratio of 112.48% in May. The average annual reported incidence rates in Anji County and Changxing County were relatively high (46.14/105 and 41.15/105). The reported incidence rate of pulmonary tuberculosis in Huzhou City increased with age (P<0.05), peaking at 97.36/105 in the group aged 75 to <80 years. There were 7 991 male pulmonary tuberculosis cases and 3 607 female cases, with a male-to-female ratio of 2.22∶1. The average annual incidence rates of pulmonary tuberculosis was higher in males than in females (50.39/105 vs. 23.87/105). Farmers were the primary occupation affected, with 6 350 cases accounting for 54.75%. Conclusions The reported incidence rate of pulmonary tuberculosis in Huzhou City decreased from 2014 to 2023, with a high incidence in spring and summer. The incidence rates in Anji County and Changxing County were higher than Huzhou City's average. Male, elderly residents and farmers were the key populations for pulmonary tuberculosis prevention and control.

Central precocious puberty (CPP) is an endocrine disease of children due to the early onset of hypothalamic-pituitary-gonadal axis function. This leads to increased secretion of gonadotropin release impulse, causing the development of internal and external genitalia and the presentation of secondary sex characteristics. Studies have found that the onset of CPP in children may be related to vitamin D deficiency. Vitamin D, affected by sunlight duration, acts on neurons and neurotransmitters in the hypothalamic-pituitary-gonadal axis, promotes obesity and affects the expression level of insulin-like growth factor-1, which are four factors involved in the occurrence and development of CPP. The overall effect of vitamin D combined with gonadotropin-releasing hormone analogues on CPP is significant. This article reviews the correlation between vitamin D deficiency and CPP, as well as the possible mechanism of action, in order to provide some theoretical basis for researchers.

Objective:To analyze epidemiological characteristics and spatiotemporal clustering of hepatitis A in China from 2005 to 2023.Methods:The incidence data of hepatitis A in China during 2005-2023 were collected from the China Disease Control and Prevention Information System .Results:From 2005 to 2023, a total of 605 509 cases of hepatitis A were reported in China. The average annual reported incidence rate was 2.32/100 000, the incidence was 2.85/100 000 in men and 1.81/100 000 in women, and the incidence was 3.25/100 000 in age group 0-14 years, 2.10/100 000 in age group 15-64 years and 2.49/100 000 in age group ≥65 years , respectively. The case count in farmers was highest (40.57%, 245 639/605 509). The proportion of the cases in jobless or the unemployed increased most obviously (347.32%), and the proportion of the cases in students decreased most significantly (90.27%). The average annual reported incidence rate in the western China was highest (4.45/100 000), followed by that in northeastern China (2.02/100 000), central China (1.89/100 000) and eastern China (1.16/100 000). From 2020 to 2023, the incidence of hepatitis A showed no spatial clustering. From 2005 to 2019, the obvious hot spots and high-high clustering areas mainly distributed in provinces, such as, Sichuan, Qinghai, Xinjiang, Xizang and Gansu. The low-low clustering areas were mainly distributed in Beijing, Tianjin, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Henan, Anhui, Jiangxi, Jilin and Liaoning. An independent high-low clustering was found in Shanxi during 2014-2019. A total of 5 high incidence clustering areas were detected through spatiotemporal scanning analysis.Conclusions:The incidence rate of hepatitis A in China declined significantly from 2005 to 2023. The reported incidence rate in the elderly showed no obvious decrease, and the reported cases accounted for the highest proportion in the whole population. Before 2020, the reported incidence rate of hepatitis A showed high-high clustering in western China, the spatiotemporal clustering disappeared from 2020 to 2023, but the reported incidence rate of hepatitis A in western China was still high. It is suggested to pay attention to the prevention and control of hepatitis A in populations at high risk and areas with high incidence of hepatitis A.

Objective:To analyze the status quo, hotspots and fronts of emergency nursing training research at home and abroad in the past ten years, and to provide reference and ideas for the efficient development of emergency nursing training in China.Methods:CiteSpace 6.2.R2 software was used to visually analyze the Chinese and English literatures on emergency nursing training included in CNKI and Web of Science core databases from January 1, 2013 to June 1, 2023.Results:A total of 1 177 Chinese literatures and 1 163 English literatures were included. The number of foreign articles in this field increased year by year, while the number of domestic articles showed a downward trend since 2018. There were many stable core author groups and core institution groups in foreign countries, while there was less cooperation among domestic authors and institutions. The common research hotspots and frontiers at home and abroad focused on broadening the training audience of emergency nursing, innovating the training methods of emergency nursing, strengthening the evaluation of the effect of emergency nursing training, and paying attention to the training experience and needs of nurses. Foreign researches also focused on specialized nurses, interprofessional education and nurses′mental health, etc, and the research direction was diversified.Conclusions:The development stages of emergency nursing training researches at home and abroad are different, and the research hotspots are different. In the future, we should learn from foreign research, strengthen interdisciplinary cooperation, improve the depth and breadth of research, and strengthen the cooperation between authors, institutions and countries to promote the high-quality development of emergency nursing training research in China.

Objective To evaluate the effect of preoperative visits using virtual reality(VR)tech-nology on alleviating perioperative anxiety in children undergoing adenotonsillectomy for obstructive sleep ap-nea syndrome(OSAS).Methods Sixty children with OSAS scheduled for elective adenotonsillectomy were selected,including 32 males and 28 females,aged 6 to 12 years,ASA physical status Ⅰ or Ⅱ.The chil-dren were randomly divided into two groups using random number table:control group and VR group,30 children in each group.The control group received routine education and preoperative visits,while the VR group used VR smart glasses to play videos of three-dimensional scenes of the operating room in addition to routine visits.The modified Yale preoperative anxiety scale-short form(m-YPAS-SF)was used to assess perioperative anxiety levels.The heart rates(HR)of the children on the day before surgery,upon entering the preparation room,and immediately after anesthesia induction,and the induction compliance checklist(ICC)was used to evaluate anesthesia induction compliance,as well as the duration of stay in the recovery room and the length of hospital stay were recorded.Results Compared with control group,the m-YPAS-SF scores in VR group were significantly lower(P＜0.05),the HR was significantly lower upon entering the preparation room and immediately after anesthesia induction(P＜0.05),and the ICC scores were signifi-cantly lower(P＜0.05),recovery room stay duration and length of hospital stay were significantly short-ened(P＜0.05).Conclusion Preoperative visits using VR can effectively alleviate perioperative anxiety in children with OSAS undergoing adenotonsillectomy which can improve anesthesia compliance and reduce the length of hospital stay.
