The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

Lung cancer （LC） is a significant global public health issue， with both its incidence and mortality rates ranking among the highest worldwide. The age-standardized incidence and mortality rates are increasing annually， posing a serious threat to the life and health of LC patients. Radical surgical resection is the primary treatment for malignant lung tumors. However， postoperative multidimensional functional impairments， including respiratory， mucosal， and psychological functions， are common. These impairments not only reduce patients' quality of life and affect their treatment tolerance and duration， but also negatively correlate with prognosis， facilitating disease recurrence and metastasis. At present， postoperative functional dysfunction after LC surgery remains a key clinical challenge that urgently needs to be addressed. There is a lack of standardized and regulated postoperative rehabilitation treatment management and traditional Chinese medicine （TCM） differentiation and treatment strategies for LC. Focusing on the core underlying pathogenesis of "Qi sinking" after LC surgery， and guided by the classical TCM theory of "lungs governing Qi"， this study， based on the core concept of the "five perspectives on treatment" theory， innovatively proposes the respiratory dysfunction as the core pathogenesis of "Qi sinking in the chest" during the rapid rehabilitation phase， mucosal dysfunction as the core pathogenesis of "Yin deficiency and Qi sinking" during the postoperative adjuvant treatment phase， and the psychological dysfunction as the core pathogenesis of "Qi sinking with emotional constraint" during the consolidation phase. Accordingly， stage-specific dynamic functional protection strategies are constructed. In the rapid rehabilitation phase， the strategy emphasizes tonifying Qi and uplifting sinking Qi， with differentiation and treatment based on the principle of ''descending before ascending''. In the adjuvant treatment phase， the approach focuses on nourishing Yin and uplifting Qi， with prescription combinations that integrate unblocking and tonification. In the consolidation phase， the strategy aims to resolve constraint and uplift Qi， with clinical treatment emphasizing a combination of dynamic and static methods. At each stage of functional rehabilitation， clinical differentiation and treatment should support healthy Qi and eliminate pathogenic factors simultaneously. This study is the first to propose the concept of postoperative functional protection in TCM， offering a new approach for TCM differentiation and treatment in the full-cycle， stage-based， and dynamic protection of postoperative function in LC patients. It is expected to contribute to the construction and development of an integrated TCM-Western medicine comprehensive program for cancer prevention and treatment in China.

OBJECTIVE: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. METHODS: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups ( P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury incidence, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. RESULTS: The closed reduction rate of the study group was significantly higher than that of the control group ( P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] ( χ ²=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group ( P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the incidence of ulnar nerve injury between the two groups ( P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group ( P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups ( P>0.05). CONCLUSION In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

OBJECTIVES: To explore the expression profile of circular RNAs (circRNAs) and their potential roles in prognosis and progression of Wilms' tumor (WT). METHODS: Four pairs of WT and adjacent tissues were collected for high-throughput circRNA sequencing to identify the differentially expressed circular RNAs. RT-qPCR was used to verify the expression levels of the top 6 candidate circRNAs in the clinical samples. hsa_circ_0001900 was selected for analysis of its correlation with clinicopathological features and prognosis in 34 patients with WT. Sanger sequencing and RNase R digestion experiments were used to verify the cycling site and structural stability of hsa_circ_0001900 molecule. RESULTS: A total of 23 978 circular RNA molecules were identified in WT tissues by high-throughput circular RNA sequencing, and among them 614 were differentially expressed in WT. hsa_circ_0001900 showed the highest expression level among the differentially expressed circRNAs, which was consistent with the findings in clinical tumor samples and the sequencing results. Correlation analysis showed that hsa_circ_0001900 expression level was positively correlated with WT volume, and the children with high hsa_circ_0001900 expression had a lowered recurrence-free survival rate. The results of Sanger sequencing verified the circular splice site sequence of the molecule, and Rnase R digestion assay confirmed its stable covalent structure. CONCLUSIONS This study presents a comprehensive expression profile of circular RNAs in WT, and the expression level of hsa_circ_0001900 is related to the size of WT and the patients' prognosis, suggesting its possible role as a key driving gene in WT progression.

Objective:To analyze the correlation between MRI indicators and clinical features of multifidus degeneration in patients with unilateral lumbar disc hemiation. Method:Eighty-six eligible patients with unilateral lumbar disc hemiation admitted to our hospital from Janu-ary 2018 to December 2021 with complete clinical data were retrospectively analyzed and divided into three groups according to the level and number of lumbar disc hemiation:27 patients in group A were treated with L4/5 disc hemiation only,30 patients in group B were treated with L5/S1 disc hemiation only,and 29 pa-tients with multi-level lumbar disc hemiation in group C.All patients underwent lumbar MRI scans,and the measurements included the ratio of the total cross-sectional area of the unaffected and affected sides of the multifidus muscle at L4/5 and L5/S1 levels,the degree of bilateral multifidus muscle atrophy,and the propor-tion of fatty infiltration.The lumbar visual analogue scale(VAS),Oswestry disability index(ODI)and other clinical features of patients with lumbar disc herniation were obtained from the medical records,and Spearman correlation was used to analyze the correlation between the ratio of the total cross-sectional area of the unaffect-ed and affected sides of the multifidus muscle at L4/5 and L5/S1 levels and the proportion of fatty infiltration. Result:There was no significant difference in age,gender and body mass index(BMI)between the groups(P＞0.05);the total cross-sectional area ratio of the unaffected and affected sides of the multifidus muscle in the three groups was positively correlated with the VAS score(P＜0.05)and not correlated with the ODI score(P＞0.05);the degree of bilateral multifidus muscle atrophy and the proportion of fatty infiltration were posi-tively correlated with the ODI score(P＜0.05)and not correlated with the VAS score(P＞0.05). Conclusion:In patients with unilateral lumbar disc herniation,the degree of asymmetry in the left and right cross-sectional areas of the multifidus muscle was associated with lumbar pain,whereas the degree of bilateral multifidus muscle atrophy and the proportion of fatty infiltration were associated with ODI scores.

Immunotherapy drugs are a class of medications that treat diseases by modulating the function of immune system.As frontline therapies in clinical practice,they play a particularly crucial role in alleviating disease symptoms and improving adverse prognoses caused by severe inflammation.In recent years,with the rapid development of internet technology and the continuous innova-tion in the technology industry,various national directives have been issued,urging schools to strengthen online teaching and promote the development of"Internet+education".Online teaching,unaffected by time or geographical constraints,has facilitated resource sharing and stimulated student interest.However,in practice,both singular online or offline teaching models have their drawbacks.This article takes the severe inflammation immunotherapy drugs as an example,integrating the concept of intersubjectivity in teaching to explore a"two-line"teaching mode in immunotherapy drugs.This study views students as the main body of learning,emphasizes the importance of individual learning,and solves the drawbacks of"one-line"teaching mode.Exploration and application of intersubjective"two-line"teaching mode has guiding significance for educational reform in the internet era.

Objective To conduct a scoping review of studies on the use of virtual reality(VR)in cancer-related cognitive impairment(CRCI),and to generalize and summarize the current state of the art of VR use in CRCI.Methods The computerized retrieval of PubMed,Embase,Web of Science,the Cochrane Library,WanFang Data,CNKI and VIP databases was carried out.Studies were collected from the database establishment to July 2023.3 researchers independently screened the literature,extracted data,and evaluated the risk of bias in the included studies.Results A total of 9 studies were included.VR was used for CRCI assessment and intervention.The assessment included visual and auditory memory,executive function and verbal fluency.The intervention content involved common cognitive impairment dimensions of CRCI,including memory,executive ability,attention,information processing speed and language fluency.The intervention frequency ranged from 3 to 5 times/week,15 to 60 min/time,and the duration was 2 to 8 weeks.The intervention frequency and intensity were dynamically adjusted based on the patient performance,game type and complexity.VR has shown good validity and benefits in CRCI assessments and interventions,while improving patients'sleep quality and ability to perform daily living,with higher patient acceptance and no VR related adverse events being reported,but its role in improving mental health remains controversial.Conclusion VR shows good validity and benefits in CRCI assessment and intervention,and has good safety and high acceptance.In the future,it is still necessary to conduct large-sample,randomized controlled studies,attach importance to the role of patient needs in the formulation of VR cognitive intervention programs,and increase CRCI-related objective indicators to further verify the effect of VR intervention on CRCI.At the same time,longitudinal evaluation and follow-up programs may be considered to determine progressive changes in CRCI from VR interventions.

Objective:To summarize the distributional characteristics of postoperative occurrence of multi-drug resistant organism (MDRO) infections and their risk factors in simultaneous pancreas-kidney transplantation (SPK) recipients and examine the impact of MDRO infections on the survival of SPK recipients.Method:From January 2016 to December 2022, the relevant clinical data were retrospectively reviewed for 218 SPK recipients. The source of donor-recipient specimens and the composition percentage of MDRO pathogens were examined. According to whether or not MDRO infection occurred post-transplantation, they were assigned into two groups of MDRO (98 cases) and non-MDRO (120 cases). The clinical data of two groups of donors and recipients were analyzed. And the risk factors for an onset of MDRO infection were examined by binary Logistic regression. The survival rate of two recipient groups was compared by Kaplan-Meier method.Result:A total of 98/218 recipients (45%) developed MDRO infections. And 46 (46.9%) of sputum and 34 (34.7%) of urine were cultured positively and 49 (50%) pathogens expressed extended spectrum beta-lactamase. There were pneumonia (46 cases, 46.9%), urinary tract infections (34 cases, 34.7%), abdominal infections (16 cases, 16.3%) and bloodstream infections (2 cases, 2.0%). Univariate regression analysis revealed that length of renal failure ( P=0.037), length of hospitalization ( P<0.001), length of antibiotic use ( P<0.001), novel antibiotics ( P=0.014), albumin ( P<0.001) and leukocyte count ( P<0.001) were risk factors for an onset of MDRO infections. The results of multifactorial regression indicated that low albumin ( OR=0.855, 95% CI: 0.790~0.925, P<0.001) and leukopenia ( OR=0.656, 95% CI: 0.550~0.783, P<0.001) were independent risk factors for an onset of MDRO infections. The survival rates of recipients in MDRO group at Year 1/3 post-operation were 92.9% (91/98) and 89.8% (88/98). And the survival rate of recipients in non-MDRO group was 96.7% (116/120) at Year 1/3 post-operation. Inter-group difference was not statistically significant in 1-year survival rate of two recipient groups ( P=0.201); statistically significant inter-group difference in 3-year survival rate between two recipient groups ( P=0.041) . Conclusion:Low albumin and leukopenia are risk factors for MDRO infection. Infection with MDRO has some impact on the survival of recipients.

Objective To identify the key genes differentially expressed in Wilms tumor and analyze their potential impacts on prognosis and immune responses of the patients. Methods High-throughput RNA sequencing was used to identify the differentially expressed mRNAs in clinical samples of Wilms tumor and paired normal tissues, and their biological functions were analyzed using GO, KEGG and GSEA enrichment analyses. The hub genes were identified using STRING database, based on which a prognostic model was constructed using LASSO regression. The mutations of the key hub genes were analyzed and their impacts on immunotherapy efficacy was predicted using the cBioPortal platform. RT-qPCR was used to verify the differential expressions of the key hub genes in Wilms tumor. Results Of the 1612 differentially expressed genes identified in Wilms tumor, 1030 were up-regulated and 582 were down-regulated, involving mainly cell cycle processes and immune responses. Ten hub genes were identified, among which 4 genes (TP53, MED1, CCNB1 and EGF) were closely related to the survival of children with Wilms tumor. A 3-gene prognostic signature was constructed through LASSO regression analysis, and the patients stratified into with high- and low-risk groups based on this signature had significantly different survival outcomes (HR=1.814, log-rank P=0.002). The AUCs of the 3-, 5-and 7-year survival ROC curves of this model were all greater than 0.7. The overall mutations in the key hub genes or the individual mutations in TP53/CCNB1 were strongly correlated with a lower survival rates, and a high TP53 expression was correlated with a poor immunotherapy efficacy. RT-qPCR confirmed that the key hub genes had significant differential expressions in Wilms tumor tissues and cells. Conclusion TP53 gene plays an important role in the Wilms tumor and may potentially serve as a new immunotherapeutic biomarker as well as a therapeutic target.
