Objective:To investigate the transcriptomic signature of refractory nasal polyps (NP) after endoscopic sinus surgery.Methods:Tissue samples were collected from 36 patients with NP who underwent endoscopic sinus surgery at the Seventh Affiliated Hospital of Sun Yat-sen University and the First Affiliated Hospital of Sun Yat-sen University from January 2020 to December 2021. Raw sequencing data of normal nasal mucosa samples were downloaded from publicly available GEO database (Accession Number: GSE136825). Differential expression genes (DEGs) and Gene Ontology (GO) enrichment analysis were conducted to analyze the differences between refractory NP and normal controls, as well as among refractory, controlled, and partially controlled NP. Hierarchical clustering method was employed to analyze the inflammatory endotypes of NP. Weighted Gene Co-expression Network Analysis (WGCNA) and STRING database were used in combination with Cytoscape software to identify the characteristic transcriptional expression profiles of refractory NP. R software (version 4.3.1) was used for statistical analysis.Results:Refractory NP patients had significantly higher asthma comorbidity rates than controlled/partially controlled groups ( P<0.05). The numbers and percentages of peripheral blood and tissue eosinophilic granulocytes were significantly higher in the refractory subgroup than in the other two subgroups ( P<0.05). Compared to normal mucosa, controlled and partially controlled NP groups, 27 genes were consistently upregulated in refractory NP. Hierarchical cluster analysis showed that the refractory NP exhibited a mixed endotype dominated by type 2 inflammation with co-existing type 1 features. Differential genes were enriched in extracellular matrix organization, leukocyte activation, cytokine receptor activation, cystatin-mediated protease inhibition, granule exocytosis, and olfactory nerve development regulation. Further WGCNA analysis and protein-protein interaction network identified 33 hub genes represented by ITGAM, NCF1, NCF2, CD1C, PTAFR, CLEC10A, SIRPA, TREM2, ALOX5AP, PTGDR2 (officially PTGDR), F13A1, DUOX2, NOS2, CTSG, and SALL1.Conclusion:This study reveals the distinctive transcriptional signature of refractory NP through transcriptomic methods, providing novel research avenues and therapeutic targets for the treatment of refractory NP after surgery.

Objective To understand phenotype conversion in patients with first-episode depression over a 7-year period,to explore the longitudinal disease characteristics and functional outcomes of transitions and non-transitions,and to further analyse the relevant factors affecting transitions.Methods A total of 346 patients with Hamilton depression scale-17(HAMD-17)score≥18,aged 18-60 years and a single episode of major depressive disorder were included in the study.They were follow-up for 7 years to assess their natural history including demographic data,disease characteristics,whether transitions to manic occurred,treatment status.At the end of the 7-year follow-up,treatment emergent symptom scale(TESS),medication adherence rating scale(MARS),and global assessment function(GAF)were used to evaluate adverse reactions,compliance to medication,and patient's overall functional level.Patients were divided into two groups based on the occurrence of mania or hypomania episodes during the 7-year period:the conversion group(those who developed episodes)and the non-conversion group(those who did not).Results A total of 138 patients were followed up for 7 years,including 54 patients(39.1%)in the conversion group and 84 patients(60.9%)in the non-conversion group.When the first episode was enrolled at baseline,the age of first episode was earlier in the conversion group than in the non-conversion group[(27.63±9.63)years vs.(41.20±11.92)years],and there were differences in marital status(unmarried 40.7%vs.7.1%,first marriage 53.7%vs.85.7%,remarriage 3.7%vs.2.4%,separated/divorced 0.0%vs.2.4%,widowed 1.9%vs.2.4%).The proportion of patients with precipitating factors was lower in the conversion group(29.6%vs.48.8%)and shorter duration of untreated psychosis(DUP)[60(15,90)d vs.90(30,180)d].The treatment method in the conversion group had lower only used antidepressant drugs(61.1%vs.81.0%)and more antidepressant combined with mood stabilizers(31.5%vs.16.7%)(all P<0.05).In the 7 years,total number of episodes in the conversion group was more than in the non-conversion group(4.33±1.21 vs.2.70±1.25,P<0.05).By the end of 7 years,the GAF score was lower in conversion group than in the non-conversion group(66.57±8.22 vs.69.21±7.20,P<0.05).Dichotomous unconditional logistic regression analyses revealed that age at first episode(OR=1.109,95%CI:1.058-1.161,P<0.001),DUP(d)(OR=1.005,95%CI:1.001-1.009,P=0.017),was an independent influencing factor on conversion over a 7-year period in patients with first-episode depressive disorders.Conclusion The rate of conversion over 7 years in patients with first-episode depressive disorder is 39.1%in the present cohort and converted patients had relatively earlier age of onset,more pre-onset without inducement,shorter DUP(d),more recurrence,higher the rate of combined treatment and worse overall functional outcome.

Objective To analyze the epidemiology and trends of measles,tuberculosis,pertussis,scarlet fever,influenza,mumps and rubella in Beijing between 2014 and 2023 in order to provide data for prevention and control of related diseases.Methods Data on the incidences of seven respiratory infectious diseases in Beijing between 2014 and 2023 was collected.Descriptive epidemiological methods were employed to analyze their demographic,temporal and spatial distribution.Joinpoint regression analysis was used to assess temporal trends in incidence.Results A total of 1 406 777 cases of seven respiratory infectious diseases were reported in Beijing between 2014 and 2023,which corresponded to an average crude rate of 649.76/100 000 reported annually.The crude rate of incidencewas higher among females than among males,with the most vulnerable age groups being 0-4 years and 5-19 years,and was higher in the six districts than on the outskirts.Most of the respiratory infectious diseases peaked in winter and spring.The annual increase in the incidence of respiratory infectious diseases in Beijing in this period averaged 27.27％,with no statistically significant differences in trends.The incidence rates of measles,tuberculosis,scarlet fever,mumps and rubella decreased significantly while those of pertussis and influenza increased,but with no statistically significant difference.Conclusion The overall incidence of major respiratory infectious diseases in Beijing is increasing.It is recommended that more people get vaccinated,surveillance of such diseases as pertussis and influenza be enhanced,and regional health resources be allocated more effectively,all of which will be critical to subsequent prevention and control of respiratory infectious diseases in Beijing.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

Cell is the most basic unit of life,and normal metabolism is the key to cell growth and development.Reactive oxygen species(ROS)are important regulators of cell function,and hypoxi-a-inducible factor-1 alpha(HIF-1α)is a ROS receptor,which can activate transient receptor poten-tial vanilloid(TRPV)channel.TRPV is a sensor for temperature,pain,and osmotic pressure.Changes in the environment can induce changes in the activity of TRPV channel,which regulates various physiological and pathological processes of cells through its downstream signaling path-ways.Low temperature plasma can regulate cellular TRPV channel activity through HIF-1α.This article mainly reviews the effect of HIF-1α on cell function through TRPV channel,which has ref-erence significance for future research on various diseases related to TRPV channel and their pre-vention and treatment,as well as provides a new idea for using low temperature plasma technology to treat diseases through regulating TRPV channel.
