[摘 要] 目的:探究着丝粒蛋白M(CENPM)在脑胶质瘤中的表达特征、临床预后价值及其对肿瘤恶性生物学行为的调控机制,为脑胶质瘤的精准治疗提供潜在靶点。方法:基于中国胶质瘤基因组图谱(CGGA)和癌症基因组图谱(TCGA)数据库分析CENPM在胶质瘤中的表达及其与患者临床病理特征和预后的相关性。通过基因本体论(GO)分析、京都基因与基因组百科全书(KEGG)富集分析和单细胞转录组分析探索CENPM的生物学功能和作用机制。WB法检测CENPM在胶质瘤细胞(LN-18、LN-229、U-138MG、U-251MG)和正常胶质细胞(HEB)中的表达;构建CENPM敲低细胞后,通过CCK-8、集落形成、Transwell和划痕实验评估恶性表型改变。结果:CENPM在WHO高级别胶质瘤中呈高表达(P < 0.05),与肿瘤恶性程度正相关。高表达组患者总体生存期显著短于低表达组(P < 0.01),Cox回归证实CENPM是影响胶质瘤患者预后的独立危险因素(P < 0.05)。功能富集分析结果显示CENPM相关基因主要富集于细胞周期调控、PI3K-Akt通路和免疫相关过程。单细胞分析结果显示CENPM主要在CD8⁺ T细胞高表达,并通过PTN-PTPRZ1/NCL配受体调控细胞通信。体外实验证实CENPM在胶质瘤细胞表达高于正常胶质细胞(LN-18:P < 0.01,LN-299:P < 0.05);敲低CENPM显著抑制迁移(P < 0.05),但增强集落形成,提示其在肿瘤进展中的双重调控作用。结论:CENPM作为胶质瘤独立预后危险因子,通过调控细胞周期、PTN通路和免疫微环境驱动肿瘤进展,其差异化调控机制(抑制迁移、促进增殖)具有潜在的临床转化价值,可作为分子分型和靶向治疗候选标志物。

Objective To analyze the disease burden and trends of bladder cancer in China and globally from 1992 to 2021. Methods Using the GBD 2021 database, the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) rates of bladder cancer in China and globally from 1992–2021 were analyzed. Average annual percentage change (AAPC) was calculated using Joinpoint regression. Subgroup analyses by sex and age were conducted, and a Bayesian age-period-cohort (BAPC) model was used to predict trends in age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) for the next 15 years. Results In 2021, China reported 106 000 new cases (ASIR: 5.14/100 000), 571 000 prevalent cases (age-standardized prevalence rate, ASPR: 26.61/100 000), 43 000 deaths (ASMR: 2.34/100 000), and a DALY rate of 45.31/100 000. From 1992–2021, China showed upward trends in ASIR and ASPR but declines in ASMR and DALYs, while global ASIR, ASMR, and DALYs decreased overall with slow ASPR growth. The peak cases in China and globally were both concentrated in the 65-79 age group, with a significantly higher burden on males than females. In China, smoking-related ASMR and ASDR exceeded global averages and rose, whereas high glucose-related indexes were lower and declined. Projections for 2021–2036 indicated that the global incidence and mortality rates would be rising, but ASIR/ASPR would be declining, while in China, the incidence rate would continue to rise, and the mortality rate will stabilize, with a significant increase in ASIR and a gradual decrease in ASPR. Conclusion From 1992 to 2021, the incidence of bladder cancer in China has shown a continuous upward trend and is projected to persist in the future, with significant gender and age differences. Particular attention should be given to elderly males aged 85-89. The disease burden of bladder cancer attributable to smoking continues to rise, highlighting the urgent need to strengthen tobacco control policies.

Ulcerative colitis (UC) is a chronic, non-specific intestinal inflammatory disease. Its pathogenesis is complex, involving interactions among genetic, immune, and environmental factors, and remains incompletely elucidated. Mitochondrial damage can trigger the abnormal release of mitochondrial damage-associated molecular patterns (mtDAMPs), activating inflammatory pathways and thereby exacerbating the inflammatory response in UC. Mitophagy, a core mitochondrial quality control mechanism, can clear damaged mitochondria and effectively reduce the abnormal release of mtDAMPs and the accumulation of harmful substances, thereby mitigating inflammatory damage resulting from mitochondrial dysfunction. Mitophagy plays a crucial role in maintaining the integrity of the intestinal epithelial barrier function and in the prevention and intervention of UC. Notably, the function of the spleen governing transportation and transformation in traditional Chinese medicine shares similarities with the role of mitochondria in energy transformation and substance metabolism. Furthermore, the pathological state of the spleen failing in transportation and transformation may be related to mitochondrial dysfunction, while the pathogenic characteristics of "endogenous turbid pathogen" align with the inflammatory cascade responses triggered by abnormal release of mtDAMPs. Based on this theoretical correlation, this paper aims to explore the correlation between the traditional Chinese medicine theory of "spleen dysfunction in essence distribution leading to endogenous turbid pathogens" and mitophagy. Using the correlation as an entry point, the potential role of mitophagy in the pathogenesis of UC was elucidated. Additionally, by considering the epidemiological characteristics of UC in the Southwest region of China, a new thinking for the treatment of UC from the perspective of turbid pathogens was proposed based on the "fortifying the spleen and resolving turbidity" method to provide theoretical support and research enlightenment for further exploring the prevention and treatment of UC with traditional Chinese medicine.

BACKGROUND:Studies have shown that rheumatoid arthritis and osteoporosis are positively correlated,but the causal relationship and related mechanisms have not yet been confirmed.With the cross-fertilization of computer science and life sciences,Mendelian randomization and bioinformatics analyses based on genome-wide association study(GWAS)and transcriptome sequencing data can assess the causal relationship between two diseases,explore the related mechanisms,and mine the therapeutic targets,which will be beneficial to the precision treatment of rheumatoid arthritis combined with osteoporosis.OBJECTIVE:To explore the causal relationship between rheumatoid arthritis and osteoporosis using two-sample Mendelian randomization and to mine potential co-morbid targets and potential targeted drugs through summary-data-based Mendelian randomization and bioinformatics analyses,aiming to provide theoretical basis for mechanism exploration and precision treatment in the field of rheumatoid arthritis combined with osteoporosis.METHODS:(1)Firstly,GWAS data of rheumatoid arthritis,osteoporosis,and cis-expression quantitative trait locus(cis-eQTL)in Asian and European populations were downloaded from the GWAS Catalog,IEU Open GWAS,FinnGen,and eQTLGen databases,and were used for two-sample Mendelian randomization analysis and summary-data-based Mendelian randomization analysis.(2)Transcriptome sequencing data of rheumatoid arthritis(GSE93272 and GSE15573)were downloaded from the GEO database for bioinformatics analysis.(3)Subsequently,forward and inverse Mendelian randomization analyses between rheumatoid arthritis and osteoporosis were performed,and inverse variance weighted was used as the main metric for the analyses,and the results were corroborated with MR Egger,simple mode,weighted median and weighted mode.(4)Then,the genes closely related to rheumatoid arthritis and osteoporosis were identified based on the summary-data-based Mendelian randomization analysis,and the co-disease targets of rheumatoid arthritis and osteoporosis were mined based on cross-analysis.Meanwhile,the biological functions of the co-morbid targets were verified based on bioinformatics analysis and cellular experiments.(5)In addition,a rheumatoid arthritis risk prediction nomogram was constructed based on DYRK2,and its prediction performance was verified by receiver operating characteristic curve,correction curve and decision curve.Finally,the target potential drugs were mined based on Enrichr database and molecular docking was performed.RESULTS AND CONCLUSION:(1)Forward Mendelian randomization analysis of rheumatoid arthritis and osteoporosis showed statistically significant results except for GCST90044540 and GCST90086118,and all other results indicated a significant causal relationship and positive correlation between rheumatoid arthritis and osteoporosis.(2)Inverse Mendelian randomization analysis suggested that no significant causal relationship was seen between osteoporosis and rheumatoid arthritis.(3)Summary-data-based Mendelian randomization analysis identified a total of 412 and 344 genes positively associated with rheumatoid arthritis and osteoporosis,and 421 and 347 genes negatively associated.Based on the cross-analysis,26 co-morbid genes were subsequently obtained.Among them,DYRK2 was a potential therapeutic target,and subsequent bioinformatics analysis and cellular experiments confirmed its important role in the progression of rheumatoid arthritis and osteoporosis.(4)Furthermore,the constructed nomogram has excellent predictive performance.Finally,four potential DYRK2-targeting drugs(undecanoic acid,metyrapone,JNJ-38877605,and ACA)were discovered and molecular docking also demonstrated reliable targeting ability.(5)In conclusion,based on GWAS data from Asian and European populations,we successfully demonstrated that rheumatoid arthritis and osteoporosis are causally related at the genetic level,DYRK2 is a potential therapeutic target,and four small molecules are potential target drugs.

BACKGROUND:Several observational studies have found a strong association between thyroid function and its related disorders and osteoporosis,but the causal relationship is unclear.OBJECTIVE:To ascertain the causal relationship between genetically predicted thyroid function and its associated disorders,as well as osteoporosis,through the Mendelian randomization analysis with extensive pooled genetic data.METHODS:Pooled data from genome-wide association studies were employed to investigate the causal relationship between thyroid function and its associated disorders and osteoporosis.This was achieved through the utilization of the inverse variance weighting method as the primary Mendelian randomization analysis method,in conjunction with the MR-Egger method,weighted median method,simple model method,and weighted model method.A two-step mediated Mendelian randomization analysis was used to calculate the mediating effect of drug-mediated thyroid dysfunction on osteoporosis and the mediating proportion.Subsequently,sensitivity analyses were conducted using the MR-Egger intercept test and MR-PRESSO to detect multiplicity,Cochran's Q test to detect heterogeneity,and leave-one-out to perform sensitivity analyses.RESULTS AND CONCLUSION:(1)The results of the inverse variance weighting method showed that thyroid function had an effect on bone mineral density,and that thyrotropin,free triiodothyronine on bone mineral density,free thyroxine,and subclinical hyperthyroidism all had a causal effect on bone mineral density.(2)In addition,mediation analyses revealed a potential mediating effect of carbimazole in the causal relationship between hyperthyroidism and the risk of developing osteoporosis,as well as a potential mediating effect of levothyroxine sodium in the causal relationship between hypothyroidism and the risk of developing osteoporosis.(3)In conclusion,thyrotropin,which is high in the normal range,has been demonstrated to increase bone mineral density.Conversely,free triiodothyronine and free thyroxine,which are also high within the normal range,as well as subclinical hyperthyroidism,have been shown to decrease bone mineral density.The risk of developing osteoporosis is partially mediated by the pathway of taking the therapeutic medication in the context of pharmacologic treatment of thyroid dysfunction.(4)The present study primarily focuses on European population data.However,given the commonality of the genetic background and the generalizability of genome-wide data analysis methods,it is of significant importance to explore the pathogenesis of osteoporosis in the Chinese population,develop effective interventions,and provide genetic counseling.

ObjectiveTo analyze the processing mechanism underlying the enhanced effect of invigorating spleen and stopping diarrhea of soil-fried Atractylodis Macrocephalae Rhizoma(AMR) by analyzing the changes of microstructure, chemical composition and anti-ulcerative colitis(UC) activity before and after soil stir-frying. MethodsThe microstructure and elemental composition of AMR before and after soil stir-frying were analyzed by scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS), to investigate the differences in microstructure and the underlying causes. Ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) coupled with UNIFI 1.9.2 natural product analysis platform were used to analyze and identify the chemical constituents in raw and soil-fried products, and multivariate statistical methods including principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to explore the differences and sources of chemical constituents between them. A dextran sulfate sodium(DSS)-induced UC mouse model was established. The method of disease activity index(DAI) was used to evaluate the severity of intestinal inflammation. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of colon tissue, enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of inflammatory factors, Real-time quantitative polymerase chain reaction(Real-time PCR) and Western blot were used to analyze the expressions of key genes and proteins involved in the intestinal mucosal barrier. The 16S rRNA sequencing was used to evaluate the diversity of intestinal flora, headspace gas chromatography-mass spectrometry(HS-GC-MS) was used to explore the levels of short-chain fatty acids(SCFAs) in feces. Base on the above findings, this paper investigated the effects of raw and soil-fried AMR on the biological, chemical, mechanical and immune barriers of model animals, and the differences in pharmacological effects and underlying mechanisms from the perspective of regulating the intestinal mucosal barrier in UC mice. ResultsSEM observation revealed numerous hearth soil particles on the surface of soil-fried AMR, accompanied by bubble-like bulges. At the same time, there were many cracks and folds on the surface of the hearth soil. EDS analysis revealed that the contents of Si, Al, Mg and Ca in soil-fried AMR were significantly higher than those of raw products, and these elements constituted the primary components of hearth soil. UPLC-Q-TOF-MS combined with database comparison was used to identify the chemical constituents of raw and soil-fried AMR. In positive ion mode, a total of 132 components were identified, primarily comprising three categories of terpenoids, polyphenols and amino acids. In negative ion mode, a total of 40 components were identified, primarily polyphenolic and glycoside compounds. Among them, the contents of sesquiterpenes and polyphenolic acids were changed significantly before and after processing. Soil-fried AMR could reduce the DAI score of UC mice, alleviate the shortening of colon length, reduce the levels of pro-inflammatory factors such as interleukin(IL)-17, IL-18, γ-interferon(IFN-γ) and tumor necrosis factor(TNF)-α in serum, increase the levels of anti-inflammatory factors such as secretory immunoglobulin A(sIgA), IL-10, IL-4 and transforming growth factor-β(TGF-β) in serum, increase the expressions of key genes and proteins of intestinal mucosal barrier such as tight junction protein-1(ZO-1), Occludin, Claudin-1 and mucin 2(MUC2) in colonic mucosa, and improve the disorders of intestinal flora diversity and the levels of SCFAs(P<0.05, P<0.01). The raw and stir-fried products of AMR also exhibited the aforementioned effects, but they were weaker than the soil-fried products. Additionally, the auxiliary material hearth soil also had a certain pharmacodynamic effect. ConclusionSoil-fried AMR can enhance the protective effect on intestinal mucosal barrier in UC mice. These changes or heating-induced alterations in the microscopic structure and chemical composition of AMR may be attributed to the dual effects of adsorption of hearth soil.

Objective To explore the application value of dual-phase dual-energy CT (DECT) perfusion imaging in preoperative lung function assessment of lung cancer patients. Methods Data were collected from patients with stageⅠA non-small cell lung cancer who underwent surgical treatment in the Department of Thoracic Surgery, the First Affiliated Hospital of Nanjing Medical University, from November 2022 to June 2024. All patients underwent DECT perfusion imaging and pulmonary function testing (PFT) before surgery. PFT observation indicators included ventilation function indicators such as forced expiratory volume in one second (FEV1), forced vital capacity (FVC), 1-second rate (FEV1/FVC), maximal voluntary ventilation (MVV), and diffusion function indicators such as diffusing capacity for carbon monoxide (DLCO) and DLCO per liter of alveolar volume (DLCO/VA). The software eXamine was used to obtain quantitative parameters of DECT perfusion imaging, including volume parameters and perfusion parameters of both lungs and each lung lobe. The correlation between the volume parameters and perfusion parameters of both lungs and the ventilation and diffusion function indicators of the patients, as well as the differences in quantitative parameters of each lung lobe, was analyzed. Results The end-inspiration lung volume and biphasic volume difference were strongly positively correlated with FEV1 and FVC (r=0.636, r=0.682, r=0.614, r=0.624, P<0.001) and moderately positively correlated with MVV and DLCO (r=0.499, r=0.514, r=0.549, r=0.447, P<0.001); the end-expiration lung volume was weakly negatively correlated with DLCO/VA (r=−0.295, P=0.026); the volume ratio was positively correlated with FEV1, FVC, MVV, and MVV% (r=0.424, r=0.399, r=0.415, r=0.310, P<0.05); the end-inspiration iodine content was weakly positively correlated with DLCO/VA% (rs=0.292, P=0.030); the end-expiration iodine content was weakly positively correlated with FEV1, FVC, MVV, DLCO%, and DLCO/VA (r=0.307, r=0.299, r=0.295, r=0.366, r=0.320, P<0.05) and moderately positively correlated with DLCO (r=0.439, P<0.001); the end-inspiration iodine concentration was negatively correlated with FEV1, FVC, MVV, and MVV% (rs=−0.407, rs=−0.426, rs=−0.352, rs=−0.277, P<0.05); the end-expiratory phase iodine concentration was moderately positively correlated with DLCO/VA (r=0.403, P=0.002); both the iodine concentration difference and the iodine concentration ratio were moderately positively correlated with FEV1, FEV1%, FVC, MVV, MVV% (P<0.05). The lung volume and iodine concentration ratio values were both highest in the left upper lung lobe and lowest in the right middle lung lobe; the differences in lung volume, lung volume ratio, intrapulmonary iodine content, and intrapulmonary iodine concentration were all highest in the lower lobes of both lungs and lowest in the middle lobe of the right lung. Conclusion Dual-phase DECT perfusion imaging can accurately assess overall lung function and quantify regional lung function.

ObjectiveTo explore the effect of tele-supervised home-based pulmonary music therapy on respiratory function, exercise capacity and clinical symptoms in patients with chronic obstructive pulmonary disease (COPD). MethodsA total of 96 COPD patients admitted to the Second People's Hospital of Lianyungang from January, 2023 to June, 2024 were selected. They were divided into control group and observation group (48 cases each) using block randomization combined with a random number table. The control group received routine treatment and nursing intervention, while the observation group added tele-supervised home-based pulmonary music therapy, for six months. Evaluations were conducted before intervention and one, three and six months after intervention. ResultsThree cases in the control group and two in the observation group dropped out. Compared to the control group, the observation group was better in forced expiratory volume in one second percentage of predicted (FEV1%) level six months after intervention (χ2 = 10.481, P < 0.001), maximal inspiratory pressure three months (Z = -2.045, P = 0.044) and six months (Z = -3.643, P = 0.033) after intervention, maximal expiratory pressure three months (Z = 2.111, P = 0.036) and six months (Z = 4.025, P < 0.001) after intervention, exercise capacity one month (t = 2.266, P = 0.028), three months (t = 3.943, P = 0.028) and six months (t = 6.703, P < 0.001) after intervention, fatigue scores three months (Z = -4.352, P < 0.001) and six months (Z = -5.718, P < 0.001) after intervention, clinical symptoms three months (t = -2.698, P = 0.007) and six months (t = -2.898, P = 0.003) after intervention, and clinical control levels three months (t = -3.402, P < 0.001) and six months (t = -5.036, P < 0.001) after intervention. ConclusionTele-supervised home-based pulmonary music therapy is beneficial in improving respiratory function, exercise capacity, fatigue, clinical symptoms and clinical control levels in patients with COPD.
