Objective To construct and compare logistic regression and decision tree models for predicting systemic inflammatory response syndrome (SIRS) in patients with type B aortic dissection (TBAD) after interventional surgery. Methods A retrospective analysis was conducted on clinical data of TBAD patients at Peking University Shenzhen Hospital from 2020 to 2024. The patients were divided into a SIRS group and a non SIRS group based on whether SIRS occurred within 24 hours after surgery. Multivariate logistic regression was used to analyze the influencing factors of SIRS occurrence in TBAD intervention patients, and a decision tree model was constructed using SPSS Modeler to compare the predictive performance of the two models. Results A total of 742 patients with TBAD were included, including 579 males and 163 females, aged 27-97 (58.85±10.79) years. Within 24 hours after intervention, a total of 506 patients developed SIRS, with an incidence rate of 68.19%. Logistic regression analysis showed that the extensive involvement of the dissection, the surgical time≥2 hours, PET coated stents implanted, serum creatinine, white blood cell count, C-reactive protein, monocyte (MONO), neutrophil count levels elevated, estimated glomerular filtration rate and decreased albumin levels were independent risk factors for SIRS (P<0.05). The decision tree model selected a total of 10 explanatory variables and 6 layers with 37 nodes, among which MONO was the most important predictor. The area under the decision tree model curve was 0.829 [95%CI (0.800, 0.856)], which was better than the logistic regression model's 0.690 [95%CI (0.655, 0.723)], and the difference was statistically significant (P<0.001). Conclusion The incidence of SIRS after TBAD intervention is high, and the decision tree model has better predictive performance than logistic regression. It can identify high-risk patients with higher accuracy and provide a practical tool for early clinical intervention.

Objective To analyze the effect of Callicarpa nudiflora on wound healing and phos-phatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/AKT/mTOR)path-way by regulating M2 macrophage polarization in rats with diabetic foot ulcer.Methods A total of 40 rats were selected,with 10 rats in control group(topical application of saline),and the remaining 30 were used to establish rat model of diabetic foot ulcer.Ultimately,27 rats were successfully mod-eled and divided into model group(topical application of saline),Callicarpa nudiflora group(topi-cal application of Callicarpa nudiflora),and Callicarpa nudiflora combined with inhibitor group(topical application of Callicarpa nudiflora combined with CD206 inhibitor,a marker protein of M2 macrophages),with 9 rats in each group.The wound healing rate,levels of basic fibroblast growth factor(bFGF)and vascular endothelial growth factor(VEGF),relative expression levels of induc-ible nitric oxide synthase(iNOS),CD16/32,CD206,PI3K,AKT and mTOR as well as mRNA ex-pression levels of PI3K,AKT and mTOR were compared among groups.Results On the 3rd,7th and 14th days after intervention,compared with the control group,the wound healing rate,VEGF,bFGF,relative expression level of CD206,relative expression of PI3K,AKT and mTOR at mRNA and protein levels were significantly decreased while the relative expression levels of iNOS and CD16/32 were significantly increased in all other groups(P＜0.05);compared with the model group,the Callicarpa nudiflora group and the Callicarpa nudiflora combined with inhibitor group showed significant increased wound healing rate,VEGF,bFGF,relative expression level of CD206,and relative expression of PI3K,AKT and mTOR at mRNA and protein levels,and significant de-creased relative expression levels of iNOS and CD16/32(P＜0.05);compared with the Callicarpa nudiflora group,the Callicarpa nudiflora combined with inhibitor group showed significant decreased wound healing rate,VEGF,bFGF,relative expression level of CD206,and relative expression of PI3K,AKT and mTOR at mRNA and protein levels,and significant increased relative expression levels of iNOS and CD16/32(P＜0.05).Conclusion Callicarpa nudiflora can promote M2 mac-rophage polarization,increase wound healing rate and levels of VEGF and bFGF in rats with diabetic foot ulcer,and activate the PI3K/AKT/mTOR signaling pathway.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Objective:To evaluate the efficacy of bevacizumab in reducing dyspnea, avoiding tracheostomy, and assessing the overall safety and effectiveness of the treatment in patients with juvenile-onset recurrent respiratory papillomatosis (JORRP).Methods:This study included 19 patients with JORRP treated with Bevacizumab at the Department of Otolaryngology-Head and Neck Surgery, BenQ Medical Center, from March 2022 to June 2024. The age of patients ranged from 1.0 to 27.0 years (10.47±8.45 years), with age at onset ranging from 0.5 to 15.0 years (3.66±3.70 years). The cohort included 11 males and 8 females. Bevacizumab was administered intravenously at a dose of 10 mg/kg every three weeks for three sessions. Efficacy was evaluated by comparing the standardized lesion volume pre-and post-treatment, with statistical analysis performed using R software (4.3.1).Results:Among the 19 patients, 11 presented with dyspnea before treatment. All patients experienced varying degrees of dyspnea relief within 72 hours following the initial treatment, and only one patient had mild dyspnea by the second treatment session three weeks later. The average reduction rates at 24 and 48 hours post-initia treatment were 25.75% and 47.16%, respectively. Following three treatment cycles, the average cumulative reduction rate was 67.47%, significantly higher than after the first treatment ( Z=3.38, P=0.002). Throughout the treatment period, no adverse events that of grade 2 or higher were noted. Conclusions:Bevacizumab can rapidly alleviate dyspnea symptoms and significantly reduce lesion volume in JORRP patients, exhibiting satisfactory overall safety and effectiveness. However additional large-scale prospective studies are warranted to validate its long-term safety and efficacy.

OBJECTIVES: In recent years, the incidence and detection rate of pancreatic cystic lesions (PCLs) have increased significantly. Endoscopic ultrasound (EUS) plays an indispensable role in the diagnosis and differential diagnosis of PCLs. However, evidence comparing the diagnostic performance of EUS-guided fine-needle aspiration (EUS-FNA) and fine-needle biopsy (FNB) remains limited. This study aims to compare the diagnostic yield, adequacy of tissue acquisition, and safety between EUS-FNA and EUS-FNB in evaluating PCLs to inform clinical practice. METHODS: A retrospective review was conducted on patients with PCLs who underwent either EUS-FNA or EUS-FNB between January 2014 and August 2021. The diagnostic yield, tissue acquisition adequacy, and incidence of adverse events were compared between the 2 groups. RESULTS: A total of 90 patients with PCLs were included (52 in the FNA group and 38 in the FNB group). The diagnostic yield was similar between the FNA and FNB groups (94.2% vs 94.7%, P>0.05). The adequacy of tissue acquisition was 71.2% in the FNA group and 81.6% in the FNB group (P>0.05). No statistically significant difference was observed in the incidence of adverse events between the 2 groups (P>0.05). CONCLUSIONS Both EUS-FNA and EUS-FNB demonstrate equally high diagnostic yields and tissue adequacy in PCLs, with excellent safety profiles. Both methods are safe and effective diagnostic tools for evaluating PCLs.

Objective:To study the cardiac morphology and function of fetuses with different types of complete transposition of the great arteries（cTGA）by using fetal heart quantification（fetal HQ）.Methods:A retrospective study was conducted on 50 fetuses diagnosed with cTGA through fetal echocardiography at Sir Run Run Shaw Hospital，Zhejiang University School of Medicine from July 2020 to December 2024. These cases were categorized into simple cTGA group（ n=31）and complex cTGA group（ n=19）based on the presence of concomitant cardiac anomalies. A control group of 160 normal fetuses with matched gestational ages was selected for comparison. Utilizing fetal HQ technology，the cardiac longitudinal diameter，transverse diameter，area，global sphericity index（GSI），left and right ventricular end-diastolic area（LVEDA，RVEDA），left and right ventricular fractional area change（LVFAC，RVFAC），left and right ventricular global longitudinal strain（LVGLS，RVGLS），and segmental sphericity index of 24 segments for both left and right ventricles（LVSI，RVSI）were measured. The analysis focused on comparing the differences among the simple cTGA group，complex cTGA group，and the control group. Results:Compared to the control group，the simple cTGA group exhibited significantly lower fetal GSI，LVEDA，RVFAC，and RVGLS（all P<0.05）. Statistically significant differences were observed in LVSI segments 1-4 and 10-17，as well as RVSI segments 1-7，9，and 15-23 compared to the control group（all P<0.05）. In comparison with the control group，the complex cTGA group demonstrated significantly reduced fetal GSI，LVFAC，LVGLS，RVFAC，and RVGLS（all P<0.05）. Significant differences were noted in LVSI segments 5-8 and 10-14，along with RVSI segments 1-14 and 24 compared to the control group（all P<0.05）. When compared to the simple cTGA group，the complex cTGA group showed significantly lower LVFAC，LVGLS，RVFAC，and RVGLS（all P<0.05），while GSI and LVEDA were significantly higher（all P<0.05）. Statistically significant differences were observed in LVSI segments 3-4，6-8，and 17，as well as RVSI segments 10-19 between the complex cTGA group and the simple cTGA group（all P<0.05）. Conclusions:The comprehensive parameters provided by Fetal HQ facilitate the assessment of cardiac morphology and function in cTGA fetuses，enabling a deeper understanding of the alterations in cardiac structure and function across different types of cTGA. This advanced analysis offers valuable reference information for clinical guidance during pregnancy.

Objective To investigate the correlation between cognitive impairment and depression in elderly patients with type 2 diabetes mellitus(T2DM).Methods Based on China Health and Retirement Longitudinal Study in 2011,totally 521 elderly T2DM patients were enrolled,and according to the results of minimum mental state examination(MMSE)and their education lev-els,they were divided into a cognitively impaired group(437 cases)and a cognitively normal group(84 cases).Center for ED Epidemiological Survey Depression Scale was used to assess the depression symptoms.The correlation between cognitive impairment and depression was analyzed.Results Compared with the cognitively normal group,the cognitively impaired group had signifi-cantly advanced age(71.98±5.29 year vs 69.42±3.98 year,P=0.000),larger proportion of de-pression(60.6％vs 35.7％,P=0.000),and higher C-reactive protein level(5.09±12.80 mg/L vs 2.25±2.43 mg/L,P=0.000),and obviously lower ratios of being married(72.1％vs 86.9％,P=0.001)and having cardiovascular disease(20.1％vs 32.1％,P=0.010),and decreased estimated glomerular filtration rate[77.15±15.88 ml/(min·1.73 m2)vs 81.91±13.55 ml/(min·1.73 m2),P=0.001].Multivariate logistic regression analysis showed that cognitive impairment was an independent risk factor for the development of depression in elderly T2DM patients(OR=3.44,95％CI:1.89-6.27,P＜0.01).ROC curve analysis indicated that the AUC value of MMSE score in predicting depression in elderly T2DM patients was 0.669(95％CI:0.626-0.709,P＜0.01).The direct effect of cognitive impairment and the mediating effect of loneliness on depression in elderly T2DM patients accounted for 72.22％and 27.78％of the total effect,respectively.Conclu-sion Cognitive impairment is associated with the presence of depression in elderly T2DM pa-tients,and loneliness plays a mediating role.

The incidence rate of coronary atherosclerotic heart disease(commonly referred to as coronary heart disease)remains high in China.In clinical practice,drug therapy,percutaneous coronary intervention(PCI),and coronary artery bypass grafting(CABG)are commonly employed.For patients with multi-vessel coronary artery stenosis,minimally invasive interventional therapy is often the preferred option.However,for those with multi-vessel disease complicated by comorbidities,CABG is generally recommended.Despite its advantages,PCI carries risks such as vascular restenosis,thrombosis,and other adverse events.Consequently,hybrid coronary revascularization(HCR)has emerged as an alternative approach.This paper provides an overview of coronary heart disease and re-views the advantages,applications,and patient selection criteria for HCR.

OBJECTIVE: To assess the clinical value of digital PCR (dPCR) for the prenatal diagnosis of common fetal aneuploidies. METHODS: A dPCR-based assay was developed for detecting trisomies 21, 18, and 13. A retrospective analysis was carried out on 173 amniotic fluid samples collected by the Prenatal Diagnosis Center of Taizhou Hospital between January 2017 and December 2023. By using chromosomal karyotyping as the gold standard, the diagnostic performance of the multiplex dPCR system was evaluated in a double-blind manner. This study has been approved by the Ethics Committee of Taizhou Hospital (Ethics No. K20250339). RESULTS: Chromosomal karyotyping has identified 59 cases of trisomy 21, 5 cases of trisomy 18, 2 cases of trisomy 13, 6 cases with chromosomal structural abnormalities or mosaicisms, and 101 cases with a normal karyotype. The dPCR results (Z-score cutoff = 4.0, CI = 99.997%) showed full concordance with karyotyping (sensitivity = 100%, specificity = 100%, Kappa = 1). Among the 6 structurally abnormal or mosaicism samples, dPCR has accurately detected 4 cases, but mis-classified 2 cases of trisomy 21 with very low-level mosaicisms (3.3%, 6.9%, respectively) as normal. CONCLUSION The established multiplex dPCR system demonstrated high diagnostic accuracy for common chromosomal aneuploidies, with results available within 24 hours. It can serve as an efficient supplementary tool to conventional chromosomal karyotyping, providing reliable support for time-sensitive clinical decision-making in prenatal diagnosis.
