ObjectiveTo evaluate the antitumor activity of Periplaneta americana extract（PAE） against human-derived lung adenocarcinoma organoids（LUAD-PDOs） and to elucidate its potential mechanism based on transcriptomics. MethodsFresh tumor and adjacent normal tissues from patients with LUAD were collected to construct LUAD-PDOs and normal lung organoid（Nor-PDOs） models using 3D organoid culture technology. The effective intervention concentration of PAE was determined using the cell counting kit-8（CCK-8） assay. Experimental groups included the model group（LUAD-PDOs）， normal group， model administration group（LUAD-PDOs+PAE）， and normal administration group（Nor-PDOs+PAE）. Hematoxylin-eosin（HE） staining was used to observe the pathological structures of PDOs， immunohistochemistry（IHC） was performed to detect the expressions of the proliferation marker Ki-67 and lung adenocarcinoma differentiation markers cytokeratin-7（CK-7） and Napsin A， TUNEL staining was applied to detect cell apoptosis. RNA sequencing（RNA-Seq） was conducted to identify differentially expressed genes（DEGs）， followed by Gene Ontology（GO）， Kyoto Encyclopedia of Genes and Genomes（KEGG）， and Gene Set Enrichment Analysis（GSEA）， alongside protein-protein interaction（PPI） network analysis to screen core mechanisms. Finally， key targets were validated by integrating external database analysis with immunofluorescence（IF）. ResultsNor-PDOs and LUAD-PDOs that highly recapitulated the pathological characteristics of the primary tissues were successfully established. The CCK-8 assay determined that the effective intervention concentration of PAE was 16 g·L^-1. Morphological observation showed that Nor-PDOs exhibited lumen-forming structures， whereas LUAD-PDOs displayed dense， solid structures. CCK-8 and TUNEL assays revealed that， compared with the model group， PAE intervention inhibited the proliferation of LUAD-PDOs and promoted apoptosis in LUAD cells， while showing no significant effect on the viability of Nor-PDOs. Transcriptomic analysis identified 719 DEGs that were significantly reversed after PAE intervention（347 up-regulated and 372 down-regulated）（P<0.05）. GO enrichment analysis indicated that DEGs in the model administration group were significantly enriched in biological processes related to cell cycle regulation compared to the model group. KEGG pathway analysis revealed that PAE affected pathways related to proliferation and metabolism， including pathways in cancer and the p53 signaling pathway. GSEA further confirmed that PAE significantly enhanced the activity of the p53 signaling pathway（P<0.05）. PPI network analysis indicated that breast cancer type 1 susceptibility protein（BRCA1） and checkpoint kinase 1（CHEK1） were the core down-regulated targets in the p53 pathway. IF verified the high expression of BRCA1 and CHEK1 in LUAD-PDOs and their significant downregulation after PAE intervention（P<0.05）. Furthermore， survival analysis based on The Cancer Genome Atlas（TCGA） database indicated that low expression of BRCA1 and CHEK1 was significantly associated with prolonged overall survival in patients with LUAD（P<0.05）. ConclusionPAE effectively inhibits proliferation of LUAD-PDOs and promotes their apoptosis， its anti-tumor mechanism is potentially associated with the activation of the p53 signaling pathway， with BRCA1 and CHEK1 genes likely serving as key downstream targets for the effects of PAE.

Based on LI Gao's Academic Thought， focusing on the process of qi transformation and taking the regulation and restoration of metabolism and immunity as the entry point， a "source-pivot-convergence" diagnostic and therapeutic model for malignant tumors is constructed. In this model， spleen and stomach internal injury is the source of malignant tumor occurrence， while the disorder of ascending and descending is the pivot of the disease development， and the generation of yin fire is the convergence of malignant tumor progression. Based on this， the three major therapeutic methods of clearing the source， harmonizing the pivot， and resolving the convergence are established. To fortify spleen and boost qi， consolidate the root and clear the source， modified Buzhong Yiqi Decoction（补中益气汤）can be used. To raise the clear and direct the turbid downward， regulate qi and harmonize the pivot， modified Shengyang Yiwei Decoction （升阳益胃汤） is suggested. To restore balance and promote circulation， disperse accumulation and resolve convergence， modified Shengyang Sanhuo Decoction （升阳散火汤） is selected. In clinical practice， these formulas can be used in combination according to the complexity of the pathogenesis， and further adapted with prescriptions for promoting dispersion and penetrating pathogenic factors， resolving phlegm and promoting circulation， activating blood and eliminating concretions， which can provide a reference for the prevention and treatment of tumor diseases.

Antibody-drug conjugates (ADCs) have emerged as a standard treatment modality for previously treated driver gene-positive advanced non-small cell lung cancer (NSCLC). Sacituzumab tirumotecan (sac-TMT), a novel TROP-2-targeting ADC, has been the focus of the phase Ⅲ clinical trial OptiTROP-Lung04. This trial demonstrated, for the first time, that single-agent sac-TMT significantly improves progression-free survival and overall survival compared with conventional platinum-based chemotherapy in patients with epidermal growth factor receptor (EGFR) mutant advanced NSCLC following resistance to EGFR tyrosine kinase inhibitors. This review combines existing consensus from literature with the latest research evidence to systematically analyze OptiTROP-Lung04 from multiple perspectives, including molecular mechanisms, study design, clinical significance, and safety management. Furthermore, it explores future development directions in an effort to provide new insights into precision therapy for advanced NSCLC.

Objective:To investigate the current status of pruritus care in dermatology departments of public hospitals in China.Methods:A multicenter, cross-sectional survey was conducted. By convenience sampling, dermatology nurses were selected from 85 public hospitals across 17 provinces in China from September 2 to September 14, 2024, and a self-designed pruritus care questionnaire survey was conducted. The survey content included two parts: general information (e.g., education levels, professional titles, regions, hospital grades) and current status of pruritus care (e.g., pruritus care systems or standards, establishment of pruritus clinics, pruritus assessment, pruritus intervention measures, pruritus nursing training, and challenges in pruritus care) .Results:A total of 607 nurses were investigated, including 322 (53.0%) from general hospitals and 285 (47.0%) from specialized hospitals; 359 (59.1%) were from tertiary grade-A hospitals. In total, 264 (43.5%) nurses reported that pruritus clinics had been established in their hospitals, 218 (35.9%) reported that pruritus nursing teams had been set up, and 283 (46.6%) noted a lack of pruritus care systems or standards in their hospitals. The most commonly used anti-pruritus measures were physical therapy (51.2%) , drug treatment (37.9%) , and environmental management (10.9%) . There were 418 (68.9%) nurses who had received pruritus nursing training. The most frequently used pruritus assessment tools were the numeric rating scale ( n = 341, 56.2%) and the visual analog scale ( n = 268, 44.2%) , while 165 (27.2%) nurses had not used any assessment tools. The most challenging issues in pruritus care were the selection of pruritus assessment tools ( n = 303, 49.9%) and poor efficacy of pruritus control ( n = 113, 18.6%) . Tertiary grade-A hospitals and hospitals with pruritus clinics exhibited higher rates of establishing pruritus care systems/standards and providing pruritus nursing training compared with non-tertiary grade-A hospitals and hospitals without pruritus clinics respectively (all P < 0.05) . Conclusions:Public hospitals in China currently face issues such as inadequate pruritus care management systems, non-standardized pruritus assessment, and insufficient pruritus nursing training. Pruritus nursing levels were variable among different hospitals, and the standardization and homogeneity of pruritus nursing urgently need to be improved.

Advances in targeted therapy and immunotherapy have significantly improved clinical outcomes for patients with advanced non-small cell lung cancer (NSCLC), reshaping treatment paradigms. However, most patients ultimately face drug resistance, with limited options for subsequent therapies and suboptimal treatment efficacy, presenting a prominent challenge in current clinical practice. Antibody-drug conjugates (ADCs), characterized by high efficacy and favorable safety profiles, have emerged as a promising therapeutic frontier in recent years. This systematic review provides a comprehensive overview of the latest advancements in ADCs-based therapies for lung cancer, alongside discussions of the prevailing challenges in this rapidly evolving domain.

Objective To explore the effects of tripterygium glycosides(TGs)on adipocyte differentiation,inflam-mation,and fibrosis of orbital fibroblasts(OFs)in thyroid associated ophthalmopathy(TAO).Methods OFs isolated from 12 TAO patients were cultured and identified.CCK-8 experiment was used to detect the effect of different concentra-tions of TGs(0,12.5,25.0,50.0,100.0 mg·L-1)on the activity of OFs.Then,adipocyte differentiation phenotypes of OFs were induced and divided into a control group,an adipocyte differentiation group(DM),and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Inflammation phenotypes of OFs were induced and divided into a control group,an IL-1 β group,and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Fibrosis phenotypes of OFs were induced and divided into a control group,a TGF-βi group,and TG groups(12.5,25.0,and 50.0 mg·L-1 TGs).Oil red O staining was used to detect the formation of lipid droplets in OFs of adipocyte differentiation phenotype.ELISA was used to measure IL-6 and TNF-α levels in OFs of inflammation phenotype and HA levels in OFs of fibrosis phenotype.Transwell experiment was used to detect the cell migration rate of OFs of fibrosis phenotype.Real time quantitative polymerase chain reaction(RT-qPCR)and Western blot were used to detect the expression levels of PPAR-γ,c/EBP-α,FABP-4,perilipin-1,and adiponectin mRNAs and pro-teins in OFs of adipocyte differentiation phenotype,the expression levels of IL-6,TNF-α,COX-2,MCP-1 and ICAM-1 mR-NAs and proteins in OFs of inflammation phenotype,and the expression levels of Vimentin,Fibronectin,COL1A1,COL1A2 and ACTA2 mRNAs and proteins in OFs of fibrosis phenotype.Results The cells were identified as OFs.12.5,25.0,and 50.0 mg·L-1 of TGs had no significant effect on OF activity and these three concentrations were used in the subsequent ex-periment.In OFs of adipocyte differentiation phenotype,the number of orange red lipid droplets greatly decreased after TG treatment.The expression levels of PPAR-γ,c/EBP-α,FABP-4,perilipin-1,and adiponectin mRNAs and proteins in cells of TG groups were significantly lower than those of the DM group(all P＜0.05).In OFs of inflammation phenotype,IL-6 and TNF-α levels in supernatant and cells of TG groups were significantly decreased,compared with those of the IL-1βgroup(all P＜0.05).The expression levels of COX-2,MCP-1,and ICAM-1 mRNAs and proteins in cells of TG groups were significantly lower than those of the IL-1 β group(all P＜0.05).In OFs of fibrosis phenotype,the cell migration rates,HA levels in cell culture supernatant,and the expression levels of Vimentin,Fibronectin,COL1A1,COL1A2,and ACTA2 mR-NAs and proteins in cells of TG groups were significant lower than those of the TGF-β1 group(all P＜0.05).Conclusion TGs can inhibit the adipocyte differentiation,IL-1 β-induced inflammatory responses and TGF-β1-induced fibrosis of TAO-OFs.

Objective To compare the effects of quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL)and erector spinae plane block(ESPB)on early postoperative recovery in patients undergoing posterior lumbar surgery.Methods Ninety-three patients,aged 25～70 years,BMI 18～30 kg/m2 and ASA physical status Ⅱ or Ⅲ and scheduled for posterior lumbar surgery,were randomly divided into QLB-LSAL combined with general anesthesia(Group Q),ESPB combined with general anesthesia(Group E),and general anesthesia alone(Group N).Postoperatively,all groups received patient-controlled intravenous analgesia(PCIA).The following parameters were recorded:the scores of Richmond Agitation-Sedation Scale(RASS)and Bergman Comfort Scale(BCS)at awakening,6 h,12 h,and 24 h postoperatively;Likert scale score at PCIA cessation;the scores of Pittsburgh Sleep Quality Index(PSQI)and Early Postoperative Quality of Recovery-15(QoR-15)at 1 day preopera-(P<0.05).(2)Compared with Group N,group Q exhibited lower PSQI scores and higher QoR-15 scores at 1 and 3 days postoperatively(P<0.05).No statistically significant difference in PSQI scores was observed between group E and N(P>0.05),while group E had higher QoR-15 score than group N only at 1 day postoperatively(P<0.05).Both at 1 and 3 days postoperatively,group Q had lower PSQI scores and higher QoR-15 scores than group E(P<0.05).(3)Postoperative awakening time,extubation time,PACU stay time,time to first anal exhaust and time to first ambulation were significantly shorter in group Q than those in group N(P<0.05).Group E only showed shorter time to first anal exhaust compared to group N(P<0.05).Furthermore,group Q had a significantly shorter PACU stay time than group E(P<0.01).(4)There was no statistically significant difference in the incidence of adverse reactions among the three groups of patients.(P>0.05).Conclusions Both QLB-LSAL and ESPB effectively improve postoperative analgesia and early recovery quality.However,QLB-LSAL demonstrates advantages in enhancing patient comfort,analgesia satisfaction,sleep quality,and accelerating overall postoperative recovery.

Chronic stress triggers the imbalance of the homeostasis of the tumor immune microenvironment(TIME),which is a key factor driving the development of lung cancer.Based on the mapping relationship between the concept of"spirit"in traditional Chinese medicine and chronic stress,and between"qi"and"immunity",it is believed that the cross-linking mechanism of"chronic stress-TIME-lung cancer"aligns with the understanding of traditional Chinese medicine of disease as involving the interplay between the"body,qi and spirit".The disorganization of"spirit"and"qi"is not only the root of the change of the"form",but also the key to prevent and control it.The treatment principle of synergizing to improve the chronic stress of"regulating the spirit"and remodeling the TIME of"invigorating the qi"is further proposed,which emphasizes on grasping the core pathogenesis of lung cancer at each stage of its evolution in order to administer medicines,drawing on the clinical experience and pharmacological research results in order to accurately hit the target,and combining special therapies like acupuncture,Chinese kungfu,sound therapy to treat the change of"shape"by modulating neuro-endocrine-immune network homeostasis,so as to provide new ideas and accessible solutions for the comprehensive prevention and treatment system of lung cancer.
