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.

ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease （CAD） complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized， double-blind， and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group， with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo， respectively， both in combination with conventional Western medication. The dose was 45.0 mg， three times daily， for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire （SAQ） scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine （TCM） syndrome score， the patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， inflammatory markers ［interleukin-18 （IL-18）， interleukin-10 （IL-10）， tumor necrosis factor-alpha （TNF-α）， CD40， etc.］， monoamine neurotransmitters ［e.g.， dopamine （DA）］， vascular endothelial function markers ［e.g.， endothelin-1（ET-1）］， adipokines， and ischemia-modified albumin （IMA）. Adverse reactions were also recorded. ResultsA total of 92 patients completed the study， with 44 in the observation group and 48 in the control group. Compared with baseline， both groups showed significant decreases in PHQ-9， GAD-7， and TCM syndrome scores following treatment （P<0.05）， along with a significant increase in SAQ scores （P<0.05）. In the observation group， DA levels were significantly increased （P<0.05）， while levels of IL-18， TNF-α， CD40， ET-1， and IMA were decreased （P<0.05）. In contrast， the control group exhibited significantly increased CD40 levels （P<0.05）. Compared with the control group after treatment， the observation group showed significant improvements in the SAQ dimensions of physical limitation， angina stability， treatment satisfaction， and disease perception， as well as in TCM syndrome score， PHQ-9 score， IL-18， CD40， ET-1， and IMA （P<0.05）. No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression， alleviate angina symptoms， and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation， improvement of vascular endothelial function， reduction of IMA， and increase of monoamine neurotransmitter levels.

Natural product-based drug combinations (NPDCs) present distinctive advantages in treating complex diseases. While high-throughput screening (HTS) and conventional computational methods have partially accelerated synergistic drug combination discovery, their applications remain constrained by experimental data fragmentation, high costs, and extensive combinatorial space. Recent developments in artificial intelligence (AI), encompassing traditional machine learning and deep learning algorithms, have been extensively applied in NPDC identification. Through the integration of multi-source heterogeneous data and autonomous feature extraction, prediction accuracy has markedly improved, offering a robust technical approach for novel NPDC discovery. This review comprehensively examines recent advances in AI-driven NPDC prediction, presents relevant data resources and algorithmic frameworks, and evaluates current limitations and future prospects. AI methodologies are anticipated to substantially expedite NPDC discovery and inform experimental validation.

Accurate evaluation of pain intensity in children is the prerequisite for implementing effective analgesic interventions, it is necessary to chose age-specific assessment tools tailored to developmental stages of children. The degrees of patin reported by children themselves are the gold standard for evaluation, and self-assessment should be prioritized when feasible. In addition, behavioral and physiological assessments also show good reliability and validity. This review summarizes current domestic and international researches on pediatric pain assessment tools and their clinical applications, aiming to provide reference for optimizing pain evaluation in pediatric practice.

Objective To compare the effects of desflurane inhalation anesthesia versus propofol total intravenous anesthesia on postoperative recovery quality in patients undergoing endoscopic transnasal pituitary adenoma resection,and to provide evidence-based recommendations for optimizing anesthetic management in this surgical population.Methods This single-center,prospective,randomized controlled trial enrolled 112 patients scheduled for endoscopic transnasal pituitary adenoma resection,who were randomly assigned to either the desflurane group(n=56)or the propofol group(n=56).The desflurane group received desflurane[0.7-1.0 minimum alveolar concentration(MAC)]combined with remifentanil for anesthesia maintenance,whereas the propofol group received propofol(4-6 mg·kg-1·h-1)with remifentanil.The primary outcome was defined as the time from discontinuation of anesthetics to achieving an Aldrete score of 9.Secondary outcomes included emergence time,extubation time,and incidences of postoperative agitation and vomiting.Results Patients receiving desflurane achieved an Aldrete score of 9 significantly faster than those in the propofol group(13.0 min vs 16.5 min,P=0.003).Similarly,both emergence time(14.0 min vs 16.5 min,P=0.009)and extubation time(13.0 min vs 16.5 min,P=0.003)were significantly shorter in the desflurane group.However,the desflurane group had higher incidences of postoperative agitation(17.9%vs 3.6%,P=0.015)and vomiting(19.6%vs 5.4%,P=0.022).No significant difference was observed in severe agitation rates or 24 h postoperative recovery quality[Quality of Recovery-15(QoR-15)scores]between groups.Conclusion Desflurane anesthesia significantly accelerates postoperative recovery in patients undergoing endoscopic transnasal pituitary adenoma resection,however,it may increase risks of mild agitation and vomiting.In clinical applications,it is necessary to balance recovery benefits against potential adverse effects,and take targeted prophylactic measures.

BACKGROUND:Adolescent idiopathic scoliosis is a common spinal deformity that seriously affects the physical and mental health of patients.Modal analysis will focus on analyzing the natural vibration characteristics of the thoracic spine and its stability and response under the influence of external vibration.This analysis is expected to not only enhance the understanding of the thoracic curvature of adolescent idiopathic scoliosis,but also provide new perspectives and methods for developing new treatment strategies,designing personalized braces,and evaluating surgical outcomes.OBJECTIVE:To create a three-dimensional finite element model to evaluate the response modes of the entire thoracic spine and intervertebral discs in adolescent idiopathic scoliosis patients at different vibration frequencies,and determine the potential frequency range of injury risk.METHODS:This study was jointly conducted at the Sixth Affiliated Hospital of Xinjiang Medical University and the School of Mechanical Engineering at the Boda Campus of Xinjiang University from June 2023 to June 2024.The research subject was a patient with severe spinal and thoracic curvature.CT images were obtained using Siemens dual source spiral CT scanning,and a fine T1-T12 three-dimensional finite element model was established using software such as Mimics,Geomagic Studio,Solidworks,and Hypermesh.Abaqus software was used to perform modal analysis on the model and obtain the maximum amplitude and corresponding vibration modes of the first 12 modes of the entire thoracic spine and intervertebral disc.RESULTS AND CONCLUSION:(1)The modal analysis results showed that the entire thoracic vertebrae and intervertebral discs mainly bent and twisted around the X and Y axes in the lower order modes,while increasing rotation around the Z axis in the higher order modes.(2)The T1-T3 and T6-T8 segments showed the most significant deformation and higher load burden,indicating that these regions played a crucial role in the development of scoliosis.(3)When the natural frequency was concentrated between 98.832 to 121.97 cycles/s for a long time,the vibration displacement of the entire thoracic vertebrae and intervertebral discs was large,which might lead to spinal injury.(4)Through finite element modal analysis,this study provides a scientific basis for understanding the response of the entire thoracic spine and intervertebral discs in adolescent idiopathic scoliosis patients under various vibration frequencies,thereby offering crucial insights into clinical treatment,prevention,and particularly,vibration-related protective strategies.Furthermore,by identifying the potential frequency range of injury risk,this study provides an important basis for developing vibration protection measures and optimizing spinal care strategies for adolescent idiopathic scoliosis patients.
