Functional dyspepsia （FD） is a prioritized disease category where traditional Chinese medicine （TCM） demonstrates distinct therapeutic advantages. The current western medicine treatment for FD is mainly based on proton pump inhibitors and prokinetic agents， with digestive enzymes， probiotics and antidepressants serving as adjuvant medication， yet such therapies still have certain limitations. TCM treatment for FD includes oral administration of Chinese herbal formulas and Chinese patent medicines， as well as external TCM therapies such as acupuncture and moxibustion， acupoint application， hot medicinal compress therapy， rubbing with ointment， medicinal iontophoresis， auricular acupoint therapy and tui na （Chinese medical massage）. The combined treatment of FD with integrated TCM and western medicine can significantly improve clinical effectiveness and reduce adverse reactions. The common mechanisms underlying the therapeutic effects of both TCM and western medicine revolve around the core pathological processes of FD， mainly focusing on restoring gastrointestinal motility， regulating the levels of brain-gut peptides， modulating intestinal microecology， and ameliorating inflammatory status. The differential mechanisms lie in the precise targeting feature of western medicine versus the holistic-regulating and multi-target characteristics of TCM， and the two approaches exert a synergistic effect to enhance efficacy. This paper proposes to leverage the advantages of TCM in holistic regulation and the strengths of western medicine in targeted treatment， so as to provide personalized and comprehensive treatment regimens for FD patients.

Objective:To investigate the role of the angiopoietin (Ang)/tyrosine kinase receptor 2 (Tie2) pathway in mediating histone-induced coagulation activation in mice with acute lung injury, and the protective mechanism of unfractionated heparin (UFH).Methods:Twenty-four mice were randomly divided into three groups ( n=8 per group): Control group, Histone group, and Histone + UFH group using the random number table method. The Histone group and Histone + UFH group were administered 50 mg/kg histone via the tail vein. One hour later, UFH was given at a dosage of 400 U/kg by the same way. The Control group was administered an equivalent volume of sterile saline solution. Four hours after modeling, tissue samples were collected. HE staining was performed to observe the pathology of lung tissue. Lung lobe wet and dry weights were measured to assess the degree of pulmonary edema. Immunohistochemistry was used to observe the expression of fibrinogen (FIB) in lung tissue. ELISA was used to detect the levels of thrombin-antithrombin complex (TAT), plasminogen activator inhibitor type-1 (PAI-1), and D-dimer (D-D) in plasma. The qRT-PCR was used to measure the mRNA expression levels of tissue factor (TF), FIB, PAI-1, angiopoietin (Ang)-1, Ang-2, and Tie2 in lung tissue. Western blot was used to measure the protein expression levels of TF, FIB, Ang-1, Ang-2, and pTie2 in lung tissue. Results:The HE staining results revealed that, compared to the Control group, the Histone group exhibited thickened alveolar walls, significant neutrophil infiltration, and alveolar congestion with edema, indicating histone-induced ALI ( P<0.001). In contrast, the Histone + UFH group exhibited milder lung injury ( P<0.001), suggesting that UFH mitigated the lung damage induced by histones. The lung wet/dry weight ratio and lung water content percentage were significantly higher in the Histone group than in the Control group ( P<0.001), while UFH reduced the severity of pulmonary edema ( P<0.01). Immunohistochemistry revealed intravascular thrombus formation and fibrin deposition in the Histone group, which were reduced by UFH. ELISA results showed significantly elevated levels of TAT, PAI-1, and D-D in the Histone group ( P<0.001), and UFH decreased the levels of these parameters stimulated by histone ( P<0.05). The qRT-PCR showed increased mRNA expression of TF, FIB, PAI-1, and Ang-2, and decreased expression of Ang-1 and Tie2 in lung tissues in the Histone group, while UFH mitigated the effects of histones on mRNA expression of these parameters. Western blot analysis indicated increased protein expression of TF, FIB, and Ang-2 ( P<0.01), and decreased expression of Ang-1 and Tie2 in lung tissues in the Histone group ( P<0.01), and UFH reduced the impact of histones on the protein expression of these parameters ( P<0.05). Conclusions:Histones can cause lung injury, pulmonary edema, and coagulation activation in mice lung tissue. UFH can effectively alleviate histone induced lung injury, and coagulation activation in by histones via the Ang/Tie2 signaling pathway.

Objective:To explore the effects of smoking on peripheral regulatory T cells (Tregs), transforming growth factor beta1 (TGF-β 1) and interleukin-10 (IL-10) in elderly patients with non-small cell lung cancer (NSCLC). Methods:This was a cross-sectional study. A total of 43 elderly patients (≥60 years old) who were hospitalized in the Department of Geriatrics Medicine, Guangzhou First People′s Hospital from January 2018 to December 2024 and were newly diagnosed with NSCLC were recruited. According to smoking history, patients were divided into non-smoking group (15 cases), low smoking group (13 cases, smoking index<400) and high smoking group (15 cases, smoking index≥400). Venous blood samples were collected from participants, plasma and cells were separated. Flow cytometry was used to measure the proportions of Tregs and the expression of forkhead box P3 (Foxp3) in peripheral blood. Plasma levels of TGF-β 1 and IL-10 were measured by enzyme-linked immunosorbent assay. The effects of smoking on peripheral Tregs, TGF-β 1, and IL-10 in elderly patients with NSCLC were analyzed. Data were analyzed by one-way ANOVA, rank-sum test, and Fisher′s exact test. Results:The proportions of Tregs in non-smoking group, low smoking group and high smoking group were 2.50% (2.32%, 2.81%), 2.83% (2.48%, 3.72%), and 3.01% (2.37%, 3.73%), respectively, and there were no statistically significant differences among the three groups ( H=3.845, P>0.05). The proportions of Foxp3 +Tregs were (3.72±0.84)%, (4.64±1.10)%, and (4.68±1.27%), respectively. The mean fluorescence intensities (MFI) of Foxp3 were 123.0 (108.0, 128.0), 131.0 (123.5, 350.0), and 222.0 (141.0, 311.0), respectively. Both the proportions of Foxp3 +Tregs and the MFI of Foxp3 were higher in low smoking group and high smoking group than those in non-smoking group (all P<0.05). However, there were no significant differences between low smoking group and high smoking group (all P>0.05). The concentrations of IL-10 were 2.27 (1.42, 3.95), 3.42 (2.30, 5.08), and 3.26 (2.35, 6.28) ng/L, respectively. There were no statistically significant differences among the three groups ( H=2.930, P>0.05). The concentrations of TGF-β 1 were (10.72±9.37), (13.46±10.39), and (25.28±16.67) ng/ml, respectively. The concentration of TGF-β 1 in high smoking group was higher than that in non-smoking group and low smoking group (all P<0.05). However, there was no statistically significant difference between low smoking group and non-smoking group ( P>0.05). Conclusions:Smoking intensity may be correlated with the immunosuppressive function of Tregs in elderly patients with NSCLC. Higher smoking levels are associated with increased Foxp3 expression in Tregs and elevated plasma levels of TGF-β 1, potentially enhancing the immunosuppressive function of Tregs.

Objective:To investigate the predictive value of a machine learning model combining contrast-enhanced ultrasound（CEUS）parameters，radiomics features of ultrasound images，and clinical data for pathological grading in bladder urothelial carcinoma（BUC）.Methods:A retrospective analysis was conducted on 174 BUC patients from Inner Mongolia Autonomous Region People 's Hospital and the First Affiliated Hospital of Baotou Medical College from December 2017 to March 2024. One hundred and thirteen BUC patients from the former hospital were randomly divided into training group and internal test group in a ratio of 7 to 3，while 61 BUC patients from the latter hospital served as an external test group. The patients were stratified into low-grade bladder urothelial carcinoma（LGBUC）and high-grade bladder urothelial carcinoma（HGBUC）groups based on pathology. Two-dimensional grayscale ultrasound images were subjected to super-resolution（SR）reconstruction，followed by extraction and screening of radiomics features in comparison with CEUS video sequences. Selected features were input into a support vector machine（SVM）to build the radiomics model. CEUS parameters，conventional ultrasound metrics and clinical data with statistical significance between LGBUC and HGBUC groups were input into SVM to construct the clinical model. The radiomics and clinical model outputs were fused via multivariate Logistic regression to form a combined model. Model performances were evaluated using ROC curves，calibration curves，and clinical decision curves. Results:Seven radiomics features from SR images were used to build the radiomics model，while CEUS parameters（peak intensity and time-to-peak half），age，tumor-wall interface and tumor-wall angle formed the clinical model. The combined model integrated these outputs. All 3 models exhibited respective strengths，the combined model showed superior robustness. The AUCs of the combined model in the training，internal test and external test groups were 0.92，0.84 and 0.82，respectively.Conclusions:The combined model combining CEUS parameters，ultrasound radiomics features，and clinical data accurately predicts BUC pathological grade，providing a potential tool for clinical diagnosis and treatment.

Objective:To explore the effect of persuasion system-based health intervention in orthodontic patients treated with clear aligners.Methods:From January 2022 to December 2023, convenience sampling was used to select patients treated with clear aligners at the Department of Orthodontics in Affiliated Stomatological Hospital of Nanjing Medical University as participants. Patients admitted from January to December 2022 were included in the control group ( n=60), and those admitted from January to December 2023 were included in the observation group ( n=59). The control group received health guidance based on the theory of knowledge, attitude, and practice. Based on the control group, the observation group added health intervention with the assistance of a persuasion system. After one year of intervention, the oral care self-efficacy, enamel demineralization, periodontal health index (gingival index, plaque index, sulcus bleeding index, probing depth), and restart rate of both groups were evaluated. Results:After the intervention, the scores of the Self-efficacy Scale for Self-care in the observation group were higher than those in the control group, and the difference was statistically significant [ (71.03±1.97) vs. (57.82±2.58), P<0.01]. The enamel demineralization rate, periodontal health index (plaque index, gingival index, sulcus bleeding index, probing depth) score, and restart rate in observation group were all lower than those in control group ( P<0.05) . Conclusions:Persuasion system system-based health intervention can improve the oral care self-efficacy of orthodontic patients treated with clear aligners, alleviate oral health issues during clear aligners, and reduce the restart rate of clear aligner patients.

Objective:To explore the clinical characteristics and genetic etiology of four children with Phelan-McDermid syndrome (PMS).Methods:Four children who had visited the Affiliated Women and Children′s Hospital of Ningbo University between June 2, 2022 and May 8, 2023 were selected as the study subjects. Clinical data of the children were collected. Genomic DNA was extracted from peripheral blood samples of the children and their parents and subjected to whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing and quantitative PCR (q-PCR) analysis. This study was approved by the Medical Ethics Committee of the Affiliated Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048).Results:All children had presented with speech and language delays and intellectual disability. Children 3 and 4 also presented with autistic behaviors. WES showed that the children 1 and 2 had respectively carried a heterozygous c.731T>C (p.Leu244Pro) and a c.2782_2851del (p.Gly928ArgfsTer4) variant of the SHANK3 gene. Sanger sequencing confirmed that their parents did not carry the same variant, suggesting that they were de novo in origin. Children 3 and 4 had respectively harbored a 121 kb and 52.02 kb heterozygous deletion at chromosome 22q13.33, which had both encompassed the SHANK3 and ACR genes mapped to 22q13.33. q-PCR results showed that the deletion of SHANK3 and ACR genes were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 731T>C and c. 2782_2851del variants were predicted to be likely pathogenic (PS2+ PM2_Supporting+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PS2_Supporting), respectively. Furthermore, the 52.02 kb and 121 kb heterozygous deletions in 22q13.33 were both predicted to be pathogenic (2D+ 4C, 1.05 in score; 2D+ 4C, 1 in score). Conclusion:The four children were all diagnosed with PMS by genetic testing. Above finding has enriched the phenotypic and mutational spectrum of PMS, and provided a basis for clinical diagnosis and genetic counseling for their families.
