Objective To investigate the epidemiological characteristics of lymphoma mortality and potential years of life lost among Wuhan residents, and to provide a scientific basis for the prevention and control of lymphoma. Methods Data on lymphoma deaths among residents in Wuhan from 2010 to 2019 were collected from the population-based Wuhan Mortality Surveillance System. Joinpoint regression model was used to evaluate the trends in age-standardized mortality rates and potential years of life lost due to lymphoma among the residents of different ages and genders. Potential years of life lost rate was used to assess the disease burden. Results There were 4 055 deaths (2481in male and 1 574 in female) from major kidney diseases in Wuhan residents between 2010 to 2019, with an age-standardized mortality rate of 5.11/100 000. The mortality rate of major kidney diseases showed an upward trend with increasing age. Between 2010 and 2019, the age-standardized mortality rates of the multiple myeloma and non-Hodgkin lymphoma were significantly increased (APC=6.924%, APC=1.407%, P＜0.05), and the potential years of life lost rate of non-Hodgkin lymphoma in female were significantly increased (APC=7.935%，P＜0.05). Conclusion From 2010 to 2019, the mortality rate of lymphoma among residents of Wuhan City shows an upward trend, especially for multiple myeloma and non-Hodgkin lymphoma. The disease burden of multiple myeloma shows an increasing trend in the female population, suggesting the need to take corresponding preventive and control measures.

ObjectiveTo systematically sort out literatures regarding telemedicine, wearable devices and artificial intelligence in pulmonary rehabilitation for chronic obstructive pulmonary disease (COPD) from 2011 to 2025, to identify the research status, hotspots and development trends. MethodsOriginal articles and reviews published from January 1, 2011 to December 31, 2025 were retrieved from Web of Science Core Collection and Scopus. Bibliometric analyses were performed via VOSviewer, CiteSpace and Scimago Graphica, including annual publication volume, collaboration networks of countries, institutions and authors, co-citation of journals and references, and keyword co-occurrence, clustering and bursting. ResultsA total of 917 literatures were included. The annual number of publications showed a sustained upward trend. The United States and the United Kingdom took the leading position in publication output and academic influence. The University of Toronto was the most productive institution, and Anne E. Holland was the most prolific author. European Respiratory Journal and American Journal of Respiratory and Critical Care Medicine were high-impact journals. COPD, pulmonary rehabilitation, telerehabilitation and telemedicine were high-frequency core keywords. Machine learning, interstitial lung disease, virtual reality and digital health were the bursting keywords in recent years. ConclusionThe researches on digital pulmonary rehabilitation for COPD are increasing continuously in the past 15 years. The research focus has shifted from hospital-based standardized rehabilitation to community home digital rehabilitation centered on patient self-management. Future studies will focus on the deep integration of multiple digital technologies and extension of rehabilitation protocols to other chronic respiratory diseases.

Objective:To explore the the possibility and potential mechanism of Coptis chinensis in treating caries based on network pharmacology and molecular docking technology.Methods:The active ingredients of Coptis chinensis and the targets of the active in-gredients and caries were obtained through a variety of databases.The intersection targets of Coptis chinensis and caries were obtained by VENNY.Based on the target of the intersection,the protein-protein interaction(PPI)networks relationship diagram was formed on the STRING platform.The core target diagram was formed through the Cytoscape software,and the Coptis chinensis-active ingre-dient-target network diagram was constructed.The intersection targets are analyzed by GO and KEGG.The core targets of Coptis chinensis active ingredients in treating caries was analyzed by molecular docking.Results:The 11 Coptis chinensis active ingredi-ents,465 targets of Coptis chinensis active ingredients and 1 160 targets of caries were obtained from the database.After analysis,71 targets of Coptis chinensis-caries intersection and 12 core targets were obtained.The potential therapeutic effect of Coptis chinensis on caries involved relaxin,phosphatidylinositol 3-kinase-protein kinase B(PI3K-Akt),mitogen activated protein kinase(MAPK),ras-re-lated protein 1(RAP1)and other signaling pathways.Berberine,one of the main active components of Coptis chinense,had strong binding activity on epidermal growth factor receptor(EGFR),matrix metalloproteinase 9(MMP9)and other core targets.Coptis chinen-sis and its active components can play a role in the treatment of caries through EGFR,MMP9 and PI3K-AKT,MAPK and other path-ways.Conclusion:Coptis chinensis and its active components can regulate several targets and signaling pathways such as EGFR,MMP9,PI3K-AKT and MAPK.Coptis chinensis may play a role in the prevention and treatment of caries through multiple pathways.

Objective:This study investigated the dynamic expression of lipocalin-2(LCN2)and its receptor,brain-type organic cation transporter protein(BOCT),in spinal cords of hSOD1G93A transgenic mice during disease pro-gression,providing potential targets for early anti-inflammatory therapy for ALS.Methods:Utilizing hSOD1G93A trans-genic mice and their wild-type littermates(WT)as animal models,this investigation examined the expression of LCN2 and BOCT at four distinct disease stages:pre-symptomatic stage(60 d),early-symptomatic stage(95 d),symptomatic stage(108 d),and late-symptomatic stage(122 d).Spinal cords were harvested,then RT-qPCR,Western blot,and immunofluorescence double-labeling techniques were employed to assess alteration expressions of LCN2 and BOCT.Ad-ditionally,BV2 cells transfected with the pcDNA3.1-G93A-SOD1 overexpression plasmid served as an in vitro hSOD1G93A BV2 microglial model.After stimulated with LPS for 24 hours,LCN2 mRNA and protein expression in hSOD1G93A BV2 microglial cells and its culture medium were measured by RT-qPCR and ELISA respectively,while BOCT expression was measured by Western blot.Results:Compared with WT mice littermates,increased expression of LCN2 mRNA was detected in the spinal cords of hSOD1G93A transgenic mice at 108 and 122 d.No significant differences were observed in LCN2 or BOCT protein expression in the spinal cords of hSOD1G93A transgenic mice from 60 to 122 d.Double-immunofluorescence labeling revealed co-localization of LCN2 and BOCT with the microglial marker Iba-1 in the ventral horn of lumbar spinal cord of hSOD1G93A transgenic mice from 95 to 122 d.In hSOD1G93A BV2 microglial model,LPS stimulation led to a significantly increased LCN2 mRNA expression and protein secretion.Conversely,there was no significant change in BOCT protein expression after LPS stimulation.Conclusion:Our findings suggest that during ALS progression,there is an enhanced expression and release of LCN2 from activated microglia,potentially exacerbating neuroinflammation and neuronal degeneration.

Conclusion:Insomnia can not only directly affect their cognitive impairment, but also indirectly affect their cognitive impairment through the chain mediation of fatigue, depression and anxiety of adolescents.

ObjectiveTo discuss the relationship between objective sleep quality and cognitive function in remission depression patients with insomnia. MethodsA total of 47 patients with depression in remission in Beijing Huilongguan Hospital were enrolled. Insomnia Severity Index （ISI） and the sleep efficiency calculated by the first four items of Pittsburgh Sleep Quality Index （PSQI） were defined as insomnia. Among the selected patients， 22 subjects were classified into insomnia group， and 25 subjects in non-insomnia group. The objective sleep status of all subjects was evaluated by polysomnography （PSG）， and the cognitive function was evaluated with the Repeatable Battery for Assessment of Neuropsychological Status （RBANS）. A regression model was established to explore the relationship between objective sleep quality and cognitive function in remission depression patients with insomnia. ResultsThere was statistically significant difference in immediate memory factor scores of RBANS between depression patients in remission with and without insomnia （t=-2.102， P<0.05）. The sleep efficiency （Z=-2.113， P<0.05）， the proportion of N3 sleep stage （Z=-3.175， P<0.01） and the duration of N3 sleep stage （Z=-3.196， P<0.01） in insomnia group were all lower than those in non-insomnia group， and the nocturnal awakening （Z=-2.058， P<0.01）， the proportion of N1 sleep stage （Z=-2.399， P<0.05） and the duration of N1 sleep stage （Z=-2.463， P<0.05） were higher than those of the insomnia group. Within insomnia group， the increased proportion of REM sleep was correlated with the improvement of attention function （β=0.953， 95% CI： 0.123~2.038， P<0.05）， and the increase of nocturnal awakening was correlated with the decline of delayed memory （β=-0.173， 95% CI： -0.325~-0.024， P<0.05）. ConclusionObjective sleep is associated with cognitive impairment in remission depression patients with insomnia， the proportion of REM sleep has a positive impact on attention function， and frequent nocturnal awakening at night has a negative impact on delayed memory.

Objective To explore the relationship and its mechanism of emphysema induced by different ways of rearing and tobacco smoke exposure with the atherosclerosis formation. Methods Forty-eight SD rats were randomly divided into 6 groups (n= 8 ,each):a normal diet + tobacco smoke exposure (TSE) group ,a fat-rich diet + TSE group ,a limit intake + TSE group ,a normal diet group ,a fat-rich diet group ,and a limit intake group for 24 weeks. Lee's index ,serum tumor necrosis factor-α (TNF-α) ,interleukin-6 (IL-6 ) ,adiponectin (APN ) levels ,mean linear intercept (MLI) ,mean alveoli number (MAN) ,the aortic pathology change ,vascular endothelial growth factor (VEGF) of aorta ,and bone morphogenetic protein-2 (BMP-2) level were collected. Results Tobacco smoke exposure ,fat-rich diet ,and limit intake increased the severity of emphysema. The microscopic features of aorta showed an early atherosclerosis in the tobacco smoke exposure groups , but no atherosclerosis in the non-smoking groups. Interactions between tobacco smoke exposure and different ways of rearing on serum APN level (F= 10.68 ,P< 0.05) were found.In the tobacco smoke exposure groups ,Pearson correlation analysis showed positive correlations of aortic VEGF and BMP-2 levels with MLI ,serum TNF-α and IL-6 levels (r= 0.431 ,0.471 ,0 ,448 ,0.449 ,0.428 , 0.447 ,all P<0.05) ,and an negative correlation with MAN (r= -0.411 ,-0.442 ,P<0.05). Conclusions Both tobacco smoke exposure and different ways of rearing can influence the formation of emphysema. There is a positive correlation between the severities of emphysema and atherosclerosis , and systemic inflammation may be involved.
