Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

BACKGROUND: Generalized pustular psoriasis (GPP), a rare and recurrent autoinflammatory disease, imposes a substantial burden on patients and society. Awareness of GPP in China remains limited. METHODS: This cross-sectional survey, conducted between September 2021 and May 2023 across 14 hospitals in China, included GPP patients of all ages and disease phases. Data collected encompassed demographics, clinical characteristics, economic impact, disease severity, quality of life, and treatment-related complications. Risk factors for GPP recurrence were analyzed. RESULTS: Among 127 patients (female/male ratio = 1.35:1), the mean age of disease onset was 25 years (1st quartile [Q1]-3rd quartile [Q3]: 11-44 years); 29.2% had experienced GPP for more than 10 years. Recurrence occurred in 75.6% of patients, and nearly half reported no identifiable triggers. Younger age at disease onset ( P  = 0.021) and transitioning to plaque psoriasis ( P  = 0.022) were associated with higher recurrence rates. The median diagnostic delay was 8 months (Q1-Q3: 2-41 months), and 32.3% of patients reported misdiagnoses. Comorbidities were present in 53.5% of patients, whereas 51.1% experienced systemic complications during treatment. Depression and anxiety affected 84.5% and 95.6% of patients, respectively. During GPP flares, the median Dermatology Life Quality Index score was 19.0 (Q1-Q3: 13.0-23.5). This score showed significant differences between patients with and without systemic symptoms; it demonstrated correlations with both depression and anxiety scores. Treatment costs caused financial hardship in 55.9% of patients, underscoring the burden associated with GPP. CONCLUSIONS The substantial disease and economic burdens among Chinese GPP patients warrant increased attention. Patients with early onset disease and those transitioning to plaque psoriasis require targeted interventions to mitigate the high recurrence risk.

Objective To investigate the current status of cleaning,disinfection,and sterilization management of dental instruments in medical institutions in Henan Province,analyze potential issues in hospital infection control,and propose targeted nursing strategies.Methods A convenience sampling method was used to survey the cleaning,disinfection,and sterilization management of dental instruments in 352 medical institutions in Henan Province from February to April 2024.A self-made questionnaire was designed,covering aspects such as the handling model and personnel configuration for dental instruments,training for cleaning,disinfection,and sterilization personnel,configuration and maintenance of cleaning and disinfection equipment,use and management of small pressure steam sterilizers,and reprocessing status of dental instruments.Results A total of 352 questionnaires were distributed,with 348 valid responses.Among the 34 primary medical institutions,only 10(29.41％)had a centralized cleaning,disinfection,and sterilization model for dental instruments;13(38.24％)had dedicated personnel for cleaning,disinfection,and sterilization of dental instruments;25(73.53％)were equipped with pressure water guns.Compari-sons among medical institutions of different levels showed statistically significant differences(P＜0.001).In the 348 medical institutions,194(55.75％)arranged pre-job training for nursing personnel;143(41.09％)performed mainte-nance on cleaning and disinfection equipment once a year;52(14.94％)did not perform pre-treatment on contaminated dental instruments after use.Among the 104 institutions using small pressure steam sterilizers,21(20.19％)used Type N small pressure steam sterilizers.Conclusion The centralized management rate of dental instruments and the basic equipment configuration rate in primary medical institutions in Henan Province are relatively low.There are issues such as insufficient personnel training,neglect of equipment maintenance,improper management of small pressure steam sterilizer usage,and incomplete reprocessing procedures in medical institutions at all levels.It is recommended that nursing managers further strengthen the training of nurses in the disinfection supply center,standardize the cleaning,disinfection,and sterilization workflow for dental instruments,in order to prevent and control hospital infections.

AIM:To identify the expression characteristics of transfer RNA-derived small RNAs(tsRNAs)re-sponding to DNA damage in human hepatoblastoma HepG2 cells,and to investigate their potential functions.METHODS:Based on paired HepG2 cells and TP53 gene knockout HepG2 cells,we successfully constructed a DNA damage cellular model using adriamycin(ADR).Transcriptome analysis of small noncoding RNAs was performed to systematically identi-fy a set of tsRNAs responding to ADR and involved in p53 regulation.Functional enrichment analysis was conducted using the Kyoto Encyclopedia of Genes and Genomes(KEGG).Additionally,after silencing the expression of target tsRNA genes,the biological functions of these tsRNAs in HepG2 cells were initially confirmed through CCK-8 assay and plate colo-ny formation assay.RESULTS:DNA damage induced a set of tsRNAs involved in p53 regulation,among which tRF-5-1(tRF-5_tRNA-Gly-TCC-2-1)and tRF-i-1(tRF i_tRNA-Tyr-GTA-11-1)showed the most significant up-regulation in HepG2 cells(P<0.05).Silencing of either tRF-5-1 or tRF-i-1 gene inhibited the proliferative activity of HepG2 cells(P<0.05).CONCLUSION:A group of tsRNAs responding to DNA damage can be identified in HepG2 cell model,and tsRNAs can promote the proliferative activity of HepG2 cells,suggesting that tsRNAs may play an important role in the de-velopment and progression of liver malignancies.

Objective: To investigate the antidepressant effects of Yuanzhi (Polygalae Radix, PR) aqueous extract on chronic unpredictable mild stress (CUMS)-induced depression rat models and the underlying mechanisms. Methods: A total of 40 male Sprague Dawley (SD) rats were randomly divided into control, model, low dose of PR (PR-L, 0.5 g/kg), high dose of PR (PR-H, 1 g/kg), and fluoxetine (10 mg/kg) groups, with 8 rats in each group. Except for the rats in control group, those in the other four groups underwent CUMS-induced depression modeling. PR and fluoxetine were administered intragastrically once daily, 30 min prior to the CUMS procedure, for 14 consecutive days until the behavioral tests were performed. After CUMS modeling, the sucrose preference test (SPT), open field test (OFT), novelty-suppressed feeding test (NSFT), forced swim test (FST), and tail suspension test (TST) were employed to assess the pharmacological effects of PR on the mitigation of depressive-like behaviors in rat models. Additionally, the enzyme-linked immunosorbent assay (ELISA) was utilized to quantify the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the rats. Western blot analysis was also conducted to evaluate the protein expression levels of nuclear factor kappa-B (NF-κB), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nucleotide-binding oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein containing caspase recruitment domain (ASC), and caspase-1 in the hippocampal tissues of the rats. Immunofluorescence staining was performed to observe the morphological changes in ionized calcium-binding adapter molecule 1positive (Iba-1+) cells in the dentate gyrus (DG) of rats with CUMS-induced depression. Result: (i) Treatment with PR-H and fluoxetine resulted in significant enhancements in both the total distance and time the rats moved during tests (P < 0.01 and P < 0.05, respectively). Post-administration of PR-H and fluoxetine also led to statistically significant increase in sucrose preference among rats (P < 0.05). Besides, PR-L, PR-H, and fluoxetine treatment markedly decreased the latency of ingestion (P < 0.05, P < 0.05, and P < 0.01, respectively). As observed from the FST, PR-L, PR-H, and fluoxetine presented antidepressant effects on rats with CUMS-induced depression, leading to the reduction in time of their immobility (P < 0.05, P < 0.01, and P < 0.01, respectively). The results of TST indicated reduced immobility time in rats receiving PR-H and fluoxetine treatment as well (P < 0.01). (ii) Rats in model group showed an increase in the levels of Iba-1+ microglia in their left and right brains in comparison with control group (P < 0.01). However, such increase was negated post PR treatment (P < 0.01). Treatment with PR-L, PR-H, and fluoxetine considerably reduced the levels of inflammatory factors (TNF-α, IL-1β, and IL-6, P < 0.01). In addition, treatment of PR-L and PR-H effectively counteracted the elevated levels of NLRP3, ASC, and caspase-1, and markedly down-regulated the expression levels of phosphorylated p65 (p-p65), COX-2, and iNOS in rats’ hippocampus (P < 0.01). Conclusion Collectively, these findings indicate that PR exerts an antidepressant effect on rats with CUMS-induced depression partially through the modulation of the NLRP3 and NF-κB signaling pathways.

Objective To investigate the molecular mechanism of lipid metabolism disorder in mouse spleen tissues due to high-altitude hypoxia.Methods Ten C57BL/6 male mice were randomly divided into normoxia group(maintained at an altitude of 400 m)and high-altitude hypoxia group(maintained at 4200 m)for 30 days(n=5).Lipidomics and metabolomics analyses of the spleen tissue of the mice were conducted using liquid chromatography-mass spectrometry(LC-MS)to identify the differential metabolites,which were further analyzed by KEGG enrichment and pathway analyses,and the differential genes were screened through transcriptome sequencing.Bioinformatics analysis was conducted to identify the upstream target genes of the differential metabolites in specific metabolic pathways.RT-qPCR and Western blotting were used to detect mRNA expressions of 11β-hydroxysteroid dehydrogenase 1(HSD11B1),steroid 5α reductase 1(SRD5A1),prostaglandin-endoperoxide synthase 1(PTGS1),hematopoietic prostaglandin D synthetase(HPGDS),xanthine dehydrogenase(XDH),purine nucleoside phosphorylase(PNP),hypoxanthine guanine-phosphoribosyltransferase(HPRT)and extracellular 5'-nucleotidase(NT5E)and protein expressions of HSD11B1,SRD5A1,XDH,PNP and HPRT in the mouse spleens.Results We identified a total of 41 differential lipid metabolites in the mouse spleens,and these metabolites and the differential genes were enriched in steroid hormone biosynthesis,arachidonic acid metabolism,and purine metabolism pathways.Compared to the mice kept in normoxic conditions,the mice exposed to high-altitude hypoxia showed significantly upregulated expressions of adrenosterone,androsterone,prostaglandin D2,prostaglandin J2,xanthine,xanthosine,and uric acid in the spleen with also changes in the expression levels of HSD11B1,SRD5A1,PTGS1,HPGDS,XDH,PNP,HPRT,and NT5E.Conclusion High-altitude hypoxia can result in lipid metabolism disorder in mouse spleen tissue by affecting steroid hormone biosynthesis,arachidonic acid metabolism,and purine metabolism pathways.
