Objective: To analyze the characteristics of alcohol poisoning cases among minors receiving pre hospital 120 emergency services in Zhengzhou, providing evidence for regional management strategies of alcohol poisoning among minors. Methods: A retrospective study was conducted on 1 630 alcohol poisoning cases (aged 0-18 years) from Zhengzhou s 120 emergency system during 2017-2019 and 2023. Data on gender, age, occurrence timeframes were analyzed using t-test and χ 2 test for intergroup comparisons. Results: Annual cases were 291 (2017), 353 (2018), 483 (2019), and 503 (2023). Compared with 2017, male alcohol poisoning cases increased by 66.94% while female cases surged 104.35% by 2023. The peak incidence of alcohol poisoning among minors occurred among 16-18 year olds (85.40%), followed by 13-15 year olds (13.74%). Most cases clustered between 21:01-03:00 (60.43%), with male cases peaking at 22:01-23:00 (12.73%) and female cases peaking at 02:01-03:00 ( 11.25 %). Between 00:01-03:00, male cases progressively decreased while female cases increased. Severity distribution showed 355 mild cases (21.78%), 1 035 moderate cases (63.50%), and 240 severe cases (14.72%). Conclusions Zhengzhou region has experienced sustained growth in underage alcohol poisoning cases, predominantly occurring from evening to early morning with moderate severity, female cases demonstrate faster growth rates. Multifaceted regulatory measures should be implemented to strengthen supervision of underage drinking behaviors.

Dendrobium moniliforme (D. moniliforme) is a traditional medicinal herb widely cultivated in Asia. Flavonoids, one of the largest groups of secondary metabolites in plants, are significant medicinal components in Dendrobium species. Several subgroups of R2R3-MYB proteins have been validated to directly regulate flavonoid biosynthesis. Using PacBio sequencing technology, we assembled a high-quality chromosome-level D. moniliforme genome with a total length of 1.20 Gb and a contig N50 of 3.97 Mb. The BUSCO assessment of genome annotation was 91.4%. By integrating the genome and transcriptome, we identified biosynthesis pathway enzyme genes related to flavonoids, polysaccharides, carotenoids, and alkaloids. A total of 90 R2R3-MYBs were identified in D. moniliforme and classified into 21 subgroups. Studies on the functions of R2R3-MYB transcription factors revealed that R2R3-MYB in SG6 can up-regulate flavonoid biosynthesis. Various validation experiments, including subcellular localization, transient overexpression, UPLC-MS/MS, HPLC, yeast one-hybrid, and dual-luciferase assays, demonstrated that DMYB69 directly up-regulates the expression of enzyme genes involved in flavonoid biosynthesis, increasing the content of flavonoids such as anthocyanin, flavone, and flavonol. Additionally, DMYB44 was shown to directly up-regulate the expression of carotenoid biosynthesis enzyme genes, thereby increasing carotenoid content. This study provides an essential genome resource and theoretical basis for molecular breeding research in D. moniliforme.

Objective:To investigate the association of monocyte-to-high-density lipoprotein cholesterol ratio (MHR) with the severity of white matter hyperintensities (WMHs) and its spatial distribution.Methods:Patients admitted to the Department of Neurology, Jiangning Hospital Affiliated to Nanjing Medical University due to various chronic diseases or physical examinations between January 2023 and December 2024 were included retrospectively. Past medical history, clinical and imaging data were collected. The Fazekas scale was used to assess the severity of WMHs. According to the scoring results of periventricular WMHs (PVWMHs) and deep WMHs (DWMHs), WMHs were divided into no/mild group (0-1 points) and moderate/severe group (2-3 points). Multivariate logistic regression analysis was used to determine independent correlation factors for the severity of WMHs, PVWMHs, and DWMHs. Results:A total of 357 patients were included, aged 65.42±9.95 years, with 198 males (55.5%). There were 193 patients (54.1%) in the no/mild group and 164 (45.9%) in the moderate/severe group. Univariate analysis showed that the proportion of patients with hypertension, diabetes, history of cerebral infarction and cerebral hemorrhage, carotid plaque, and age, serum creatinine, monocyte count and MHR in the moderate/severe group were significantly higher than those in the no/mild group (all P<0.05). Multivariate logistic regression analysis showed a significant positive correlation between MHR and the severity of WMHs (odds ratio 3.138, 95% confidence interval 1.042-9.451; P=0.042). Further analysis showed a significant positive correlation between MHR and PVWMHs (odds ratio 3.384, 95% confidence interval 1.111-10.305; P=0.032), but no independent correlation with DWMHs. In addition, age and hypertension, diabetes, history of cerebral infarction and cerebral hemorrhage were significantly positively correlated with the severity of WMHs, PVWMHs and DWMHs. Conclusion:MHR is correlated with the severity of WMHs, and higher MHR is significantly associated with PVWMHs, but not with DWMHs.

Objective:To investigate the correlation between body mass index (BMI)/high-density lipoprotein cholesterol (HDL-C) ratio and cerebral small vessel disease (CSVD) in middle-aged and elderly people.Methods:Consecutive middle-aged and elderly patients (aged ≥40 years) who were hospitalized for chronic disease examinations in the Department of Neurology, Jiangning Hospital Affiliated to Nanjing Medical University between February 2022 and May 2024 were included prospectively. According to the overall burden score of CSVD, they were divided into CSVD group (≥1) and non-CSVD group (0). According to age, they divided into middle-aged group (40-59 years old) and elderly group (≥60 years old). The demographic characteristics and clinical data were collected. Binary multivariate logistic regression analysis was used to determine the independent correlation between BMI/HDL-C ratio and CSVD. Forest plot was used to analyze the correlation between BMI/HDL-C ratio and CSVD in different age groups. Results:A total of 710 patients were included, with an age of 66.0±10.0 years and 361 were males (50.8%). There were 261 patients (36.8%) in the CSVD group and 449 (63.2%) in the non-CSVD group. The BMI/HDL-C ratio in the CSVD group was significantly higher than that in the non-CSVD group (23.60±7.00 vs. 20.78±6.40; P<0.001). Multivariate logistic regression analysis showed that BMI/HDL-C ratio was an independent risk factor for CSVD in middle-aged and elderly populations (odds ratio 1.046, 95% confidence interval 1.027-1.064; P<0.001). There were 475 patients in the elderly group, of which 198 (41.7%) had CSVD; there were 235 patients in the middle-aged group, of which 63 (26.8%) had CSVD. Forest plot analysis showed that the association between BMI/HDL-C ratio and CSVD still had statistical significance in different age groups, but the effect intensity was higher in the elderly group than in the middle-aged group. Conclusion:The BMI/HDL-C ratio is independently correlated with CSVD in middle-aged and elderly population, particularly significant in the elderly population.

After the onset of ischemic stroke, microglia undergo lipid metabolic reprogramming, especially lipid droplet accumulation, which significantly affects their polarization state and inflammatory response. Lipid droplets can exacerbate neuroinflammation by synthesizing inflammatory lipid mediators, and may also have a protective effect under certain conditions. Its metabolic reprogramming involves multiple pathway regulation such as fatty acid oxidation and cholesterol efflux. This article reviews the mechanism of changes in lipid droplet metabolism of microglia and its role in the pathological process after stroke, aiming to provide new ideas for metabolic intervention strategies.

Objective:To investigate effect of SARI expression induced by IFN-β on proliferation and apoptosis of acute myelo-blastic leukemia(AML)cells,and to explore its potential regulatory molecules.Methods:qPCR and Western blot were used to screen AML cells with low SARI expression as experimental cell lines.AML cells were treated with different concentrations of IFN-β,and expression of SARI was detected by qPCR and Western blot at different time to select appropriate concentration and time of IFN-β.RNA-Seq transcriptome sequencing and KEGG enrichment analysis were used to preliminarily screen potential regulatory molecules of IFN-β-induced SARI expression in AML cells.AML cells were treated with corresponding molecular inhibitors combined with IFN-β,cell proliferation was detected by MTS assay,and apoptosis was detected by flow cytometry.To clear this molecule was involved in IFN-β-induced SARI expression on AML cell proliferation and apoptosis.Results:SARI expression in HL60 and NB4 cells were rela-tively decreased,so they were selected as experimental cell lines.After treatment with 1 ng/ml IFN-β for 12 h,SARI expression in AML cells was increased,cell proliferation was inhibited and apoptosis were increased.STAT1 was screened as a potential regulatory mole-cule for IFN-β-induced SARI expression.After inhibiting STAT1,effects of IFN-β on SARI expression,proliferation inhibition and apop-tosis promotion of AML cells were reversed significantly.Conclusion:IFN-β can promote SARI expression in AML cells by STAT1,in-hibit cell proliferation and promote apoptosis.

Purpose To explore the subcortical structure characteristics in autism spectrum disorder(ASD)aged 12-18 years old and the developmental characteristics of abnormal regions with age.Materials and Methods A total of 102 adolescents aged 12-18 years old meeting the diagnostic criteria for ASD in diagnostic and statistical manual,fifth edition and 42 gender and age matched typically developing controls were enrolled from March 2013 to January 2021 in Peking University Sixth Hospital.Structural magnetic resonance imaging scans were performed on all participants.The freeSurfer software was used to process the 3D T1 images of all participants and segment the subcortical regions.Covariance analysis was performed to compare the volumes of subcortical regions between the two groups.Analysis of variance and covariance were used to explore the developmental differences of brain regions with significant group differences within the ASD and control groups in the age groups of 12-13,14-15 and 16-18,as well as between the ASD and control groups in these age groups.Results Compared to the control group,the volumes of the right caudate,right pallidum,left hippocampus,and corpus callosum anterior region were significantly increased in the ASD group(F=4.522,5.955,7.191,5.326,P<0.05).The volume of the corpus callosum anterior region showed significant differences among the aged 12-13,14-15 and 16-18 years groups of the control group(F=5.248,P=0.01),while there was no significant difference among these three groups of the ASD group(F=2.345,P=0.101).Conclusion Adolescents with ASD aged 12-18 years show abnormalities in multiple subcortical structures,and the developmental characteristics of the corpus callosum anterior region are different from typically developing controls,suggesting that the brains of adolescents with ASD have distinct developmental features.

Building on a clear understanding of the diagnosis and treatment patterns for cold-damp epidemics， and incorporating the insights of Academician TONG Xiaolin regarding the differentiation and treatment of such epidemics， this article have distilled the key diagnostic principles. These principles primarily entail observing color and pulse， initially distinguishing between yin and yang， with treatment focusing on dispelling cold and dampness. A comprehensive approach is adopted throughout treatment， with a combination of overall strategies and tailored treatments that evolve in line with the patient's condition. In critical and severe cases， particular attention is given to aspects such as sweating， pulse analysis， and consciousness， preventing the pathogen from penetrating deeply. Efforts are made to open and close organ networks， expelling external pathogens without fixating on resolving constipation. The dosage and efficacy of herbal remedies are adjusted based on individual circumstances and clinical symptoms. The objective is to eliminate pathogens comprehensively， while being vigilant against relapses， ultimately achieving a full recovery. This overview of the thought processes and clinical principles for diagnosing and treating cold-damp epidemics will guide precise clinical practices and provide a theoretical foundation for the involvement of traditional Chinese medicine in epidemic prevention and treatment.
