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.

Allergic asthma is a complex，polygenic disease characterized by chronic inflammation and airway hyperresponsiveness. Fungus and dust mites are the most important inhaled allergens of allergic asthma，and often exist in the form of mixed allergens. In recent years，genetic studies have shown that several genes are associated with allergic asthma attacks. This article reviews the studies on the genes related to allergic asthma caused by dust mites and fungus，such as a disintegrin and metalloproteinase 33（ADAM33），interleukin-4（IL-4），glycoprotein A repetitions predominant（GARP），toll like receptor 3（TLR3），mannose-binding lectin 2（MBL2），chemokine（C-C motif）ligand 17（CCL17）and other genes .

Asthma and rhinosinusitis are both common respiratory diseases in children，with a high rate of co-morbidity，and both affect each other.The theory of “same airway，same disease” has been confirmed in recent years.However，rhinosinusitis is often underdiagnosed，and correctly recognizing，diagnosing and treating rhinosinusitis in a timely manner is conducive to asthma control.Both rhinosinusitis and asthma are highly heterogeneous diseases，with diverse and complex inflammatory endotypes and biomarkers，including eosinophils and neutrophils.This article reviews the epidemiology of rhinosinusitis and asthma co-morbidities，the inflammatory endotypes and biomarkers of rhinosinusitis，the impact of rhinosinusitis on asthma and its mechanism of influence，and the impact of treating rhinosinusitis on asthma control.

Objective:To investigate the epidemiological characteristics of lower extremity deep vein thrombosis (DVT) in patients with femoral fracture.Methods:Retrospectively analyzed were the data of 2,571 patients with femoral fracture who had been treated at the Third Hospital of Hebei Medical University from January 2019 to December 2019. There were 1,079 males and 1,492 females, aged from 14 to 96 years (average, 67.1 years). There were 1,158 femoral neck fractures, 951 femoral intertrochanteric fractures, 309 femoral shaft fractures, and 153 femoral condylar fractures. 2,414 patients were treated surgically while 157 patients non-surgically. Color Doppler ultrasonography of both lower extremities was performed to determine the occurrence of DVT before operation and every week after operation for patients undergoing surgical treatment, and within 48 hours after admission and every week during hospitalization for those undergoing non-surgical treatment. The incidence and location of DVT were recorded for different femoral fractures.Results:The incidence of DVT in this cohort was 35.5%(913/2,517), that of proximal DVT 5.3%(135/2,571), and that of distal DVT 30.3% (778/2,571). In patients with femoral neck fracture, femoral intertrochanteric fracture, femoral shaft fracture and femoral condylar fracture, the incidence of DVT was respectively 28.8% (334/1,158), 44.7% (425/951), 30.7% (95/309) and 38.6% (59/153), the incidence of proximal DVT was respectively 2.7% (31/1,158), 5.6%(53/951), 9.7% (30/309) and 13.7% (21/153), and the incidence of distal DVT was respectively 26.2% (303/1,158), 39.1% (372/951), 21.0% (65/309) and 24.8%(38/153). The incidence of DVT in the femoral vein and above, popliteal vein, tibiofibular vein and intermuscular vein in this cohort was respectively 2.3%(60/2,571), 2.9%(75/2,571), 6.4%(165/2,571) and 23.8%(613/2,571).Conclusions:The incidence of DVT may be high in patients with femoral fracture, and the proximal DVT with a high risk of pulmonary embolism may occur more in patients with femoral condylar fracture.

Objective To examine the correlation between the gene of phosphate and tension homology deleted on chromosometen (PTEN gene) polymorphism and schizophrenia (SCZ) associated with the type 2 diabetes mellitus (T2DM ) in Shanghai Han population. Methods The study recruited 591 long-stay schizophrenic inpatients including 304 with and 287 without type 2 diabetes mellitus, 206 patients with the type 2 diabetes mellitus and 205 normal subjects from Shanghai Han population. SNPs of PTEN gene (rs1234225, rs12569998, rs1234223) were genotyped by using Taqman genotyping. The frequency distributions of allele, genotype and haplotype between groups were analyzed. Results There were significant differences in the frequency of rs1234223 genotype (P=0.01) and allele distribution (P=0.02) between the SCZ with type 2 diabetes mellitus group and the SCZ without type 2 diabetes mellitus group. The difference of genotype frequencies remained statistically significant (P=0.03) but the allele distribution was not (P=0.06) after Bonferroni correction. Haplotype analysis showed that TTC haplotype was less common in the SCZ with type 2 diabetes mellitus group than in the SCZ without type 2 diabetes mellitus group (P=0.02). Conclusions PTEN gene may be a susceptibility gene for schizophrenia with type 2 diabetes mellitus in Chinese Han population. The TTC haplotype may be a protective factor for schizophrenia with type 2 diabetes mellitus.

Objective To explore humor experience and its relationship with theory of mind in patients with schizophrenia. Methods sixty?one schizophrenic patients without treatment and sixty?three healthy subjects were assessed with the Humor Picture Test ( HPT) ,Humor Video Test ( HVT) and the Theory?of?Mind Picture?Se?quencing Task ( ToM?PST) . Results Compared with healthy subject in HPT,schizophrenic patients showed sig?nificantly higher non?humor picture rating score (24.41 ± 8.82 vs 28.41 ± 11.56, P<0.05),and less humor picture rating score (45.65 ± 11.49 vs 34.41 ± 13.06, P<0.05). Compared with healthy subject in HVT,schizophrenic patients also showed significantly less humor video rating score (3.56 ± 0.57 vs 2.46 ± 0.79, P<0.01) and the number of standard humorous moments (3.68 ± 1.19 vs 2.42 ± 1.40, P<0.01) and the sensitivity of standard hu?morous moments?d’(humor) score (1.11 ± 0.46 vs 0.47 ± 0.42, P<0.01). Schizophrenic patients had significant?ly less total score (39.89 ± 12.33 vs 58.76 ± 0.64, P<0.01) of ToM?PST compared to normal control. Correlation analysis showed a negative correlation between d’ ( humor) score and the Positive and Negative Syndrome Scale ( PANSS) total score ( r=-0.380, P<0.01) for the patients. There was significantly negative correlation between non?humor picture rating score and ToM?PST total score ( r=-0.316, P<0.05) ,and positive correlation between d’ (humor) score and ToM?PST total score ( r=0.400, P<0.01) in schizophrenic patient. After controlling for the PANSS total score,the correlation between d’(humor) score and ToM?PST total score remained significant. Conclusion Schizophrenic patients have poor humor experience,which is related to the impairments of theory of mind.Humor experience deficit may share a common neuropsychological base with the impairment of theory of mind.
