Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Objective To retrospectively analyze the prevention and control effect and epidemic characteristics of elderly tuberculosis in Hubei Province from 2016 to 2020, and to provide a scientific basis for the prevention and treatment of elderly tuberculosis in Hubei Province． Methods The data on tuberculosis patients aged 60 and above who registered their current address in Hubei Province from 2016 to 2020 were collected and analyzed. The registration rates and composition ratios were analyzed using χ² test and χ² test for trend. Results A total of 135 976 tuberculosis patients were reported in Hubei from 2016 to 2020. The annual average registration rate of elderly tuberculosis among the elderly registered residence population (referring to the registration rate of elderly registered residence population aged 60 and above as the denominator, and tuberculosis patients aged 60 and above as the numerator) was 263.51/100 000. The highest rate was 300.02/100,000 in 2017, and the lowest was 188.19/100,000 in 2020 (χ²=70,227.603, P<0.001). In terms of composition, the average annual proportion of tuberculosis patients in the 60-70 years old group was 59.60%, which decreased year by year (χ²_trend=40.448，P<0.001 ). The average annual proportion of males was 73.35%, which was significantly higher than that of females (26.65%). The average annual proportion of farmers was 62.03%. From the perspective of case management, the annual average proportion of major epidemic online reports was 85.17%. The classification of cases was mainly based on clinical diagnosis, accounting for 48.33% annually and showing a decreasing trend year by year (χ²_trend=740.911, P<0.001). The proportion of confirmed cases was 25.08%, which showed an increasing trend (χ²_trend=380.557, P<0.001). From 2016 to 2019, the delay rate of diagnosis and treatment of elder tuberculosis patients was 49.42% (67 876/135 967), and the delay rate decreased year by year (χ²_trend=323.764, P<0.001). Conclusion The elderly population with pulmonary tuberculosis in Hubei Province shows a downward trend. It is necessary to focus on the efforts of designated hospitals to proactively identify cases, increase the proportion of confirmed cases, maintain a high tracking in place, reduce medical delays, and ensure the effectiveness of tuberculosis prevention and treatment for the elderly.

BACKGROUND:It was found that the ligands and receptors of Notch are both cell membrane surface proteins,which are important proteins to mediate intercellular communication,and the Notch signaling pathway plays a crucial regulatory role in the proliferation and differentiation of mesenchymal stem cells. OBJECTIVE:To review the regulatory mechanism of the Notch signaling pathway on the proliferation and differentiation of mesenchymal stem cells,summarize and clarify the research advance in how the Notch signaling pathway regulates the proliferation and differentiation of mesenchymal stem cells,and provide theoretical support for the future use of stem cells to treat various related diseases. METHODS:By using the computer,the first author searched the relevant studies involving Notch signaling pathway regulation of mesenchymal stem cell proliferation and differentiation on CNKI,Wanfang,VIP,PubMed,Web of Science,and Nature databases with Chinese search terms"mesenchymal stem cells,Notch,Notch signaling pathway,proliferation,differentiation"and the English search terms"mesenchymal stem cells,MSC,Notch,Notch signaling pathway,proliferation,differentiation".Part of the literature was searched in combination with the literature tracing method.Finally,87 articles were included in the review analysis. RESULTS AND CONCLUSION:(1)Notch signaling pathway is a conserved signaling pathway in multicellular organisms,which plays an important role in regulating cell differentiation,proliferation,apoptosis,and the cell cycle by mediating communication between neighboring cells through receptor-ligand binding.(2)Mesenchymal stem cells are a class of adult stem cells with self-proliferative and multi-directional differentiation potential,which can be regulated by external signaling pathways to affect their proliferation and differentiation.Notch signaling pathway,as one of them,when Notch ligands are activated,the Notch proteins will undergo two protein hydrolysis cleavages to release Notch intracellular structural domain NICD,which then enters the nucleus and thus promotes the transcription of target genes to regulate the proliferation and differentiation of mesenchymal stem cells from different sources,such as bone marrow,adipose,and umbilical cord.However,the specific mechanisms that regulate the proliferation and differentiation of mesenchymal stem cells from different tissue sources of the same species are different.(3)The Notch signaling pathway can regulate the differentiation of mesenchymal stem cells into different target cells,but due to different target cells,the expression levels of receptors or ligands in the Notch signaling pathway vary.(4)Clinical targeting of the Notch signaling pathway to promote mesenchymal stem cells for the treatment of various refractory diseases,such as aplastic anemia,severe joint injuries,ischemic strokes,and myocardial infarctions,has a promising application.(5)By exploring the Notch signaling pathway via regulating the expression levels of its receptors and ligands in bone marrow mesenchymal stem cells from rat,mouse,and human,it can be found that the Notch signaling pathway expression levels in the proliferation and differentiation of mesenchymal stem cells from different species origins are also different.(6)The role of mesenchymal stem cells in tissue engineering has been gradually highlighted due to their advantages of safety,low immune rejection,and wide therapeutic prospects.The Notch signaling pathway regulates the proliferation and differentiation of mesenchymal stem cells with a wide range of influencing factors,and subsequent studies should further optimize the influencing factor variables and explore the standardized studies of regulating the proliferation and differentiation of mesenchymal stem cells.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

OBJECTIVE To elucidate the mechanisms responsible for the inhibitory effects of limonene on the proliferation of non-small cell lung cancer(NSCLC) by non-targeted metabolomics and additional approaches. METHODS The CCK-8 assay was utilized to evaluate the inhibitory effects of limonene on NSCLC A549 cell viability and to ascertain the IC50. In vitro experiments, encompassing colony formation, flow cytometry, iron content assessment, and mitochondrial staining, were conducted to assess the anti-lung cancer and iron-induced cell death effects of limonene. Metabolomic analysis was employed to identify potential pathways influenced by limonene, and Western blotting was carried out to validate pivotal proteins within these pathways. RESULTS In comparison to the control group, the limonene-treated group demonstrated a significant, dose-dependent reduction in A549 cell proliferation and colony formation. Optical microscopy revealed cellular detachment and pronounced changes in cellular morphology following exposure to limonene. Limonene induced apoptosis in A549 cells and arrested them in the G0-G1 phase of the cell cycle. Confocal microscopy unveiled diminished mitochondrial fluorescence and an augmented intracellular iron content, indicative of the classical phenomenon of ferroptosis. Metabolomic investigations unveiled divergent metabolic pathways, including glutathione(GSH) metabolism, arginine biosynthesis, D-glutamine and D-glutamate metabolism, as well as cysteine and methionine metabolism, with many of them intricately linked to intracellular GSH synthesis. Western blotting experiments underscored a marked reduction in the levels of SLC40A1, SLC7A11(xCT), and GPX4 proteins within the cells post-limonene treatment. CONCLUSION Limonene may induce ferroptosis in lung cancer cells by reducing GSH synthesis and increasing Fe2+ levels.

This paper summarizes the exploration process and academic significance of the academic thought of Zhou Zhongying,a master of traditional Chinese medicine,who took the creation of a new system of TCM pathogenesis theory as the core,and interprets its theoretical connotation.As a pioneer in the construction of higher education textbooks for traditional Chinese medicine,Professor Zhou Zhongying created the outline of TCM internal medicine viscera differentiation,persisted in carrying out innovative research on patho-genesis theory,achieved fruitful academic results,and enriched and developed the academic system of TCM theory.In the clinical di-agnosis and treatment of exogenous febrile diseases and acute and difficult internal injuries,he systematically created new pathogenesis theories such as stasis-heat theory and cancer toxicity theory.Based on this,the legislation of medication can improve the clinical effi-cacy,and it is realized that identifying the pathogenesis is the key link in syndrome differentiation and treatment.In his later years,Professor Zhou Zhongying,guided by the holistic view,proposed the"thirteen pathogenesis"and constructed a new system of TCM pathogenesis differentiation,highlighting the guiding value of complex pathogenesis and the causal chain of pathogenesis elements to complex clinical diseases and syndromes,forming a theory with the idea of"examining syndromes and seeking pathogenesis,activating syndrome differentiation"as its soul.This theory breaks through the rigid thinking of syndrome differentiation and treatment based on a single pathogenesis or fixed syndrome type,reconstructs the theoretical framework of TCM with the idea of holistic view,and is a major academic innovation in modern TCM.
