With the continuous advancement of internet technology and the improvement of internet literacy among the general population, the concept of online-offline integration in internet hospitals has gradually gained acceptance and has been applied and developed both domestically and internationally. In thoracic surgery, the applicability of this model lies in enhancing efficiency and delivering comprehensive, diversified, and personalized medical services to address complex and severe conditions. However, challenges such as hardware limitations and diagnostic/treatment risks persist during the implementation of internet hospitals. Through future in-depth and localized research, the online-offline integration of internet hospitals is expected to undergo further development and refinement. This progress will facilitate its integration into clinical practice in thoracic surgery, ultimately providing patients with improved medical care services.

Objective:To investigate the clinical characteristics and major allergens of patients with pollen-food allergy syndrome（PFAS） and their correlation with the severity of symptoms, and to provide a basis for identifying high-risk patients, optimizing the allergen testing process and developing individualized dietary management strategies. Methods:The clinical data of 166 patients with PFAS admitted to our hospital from January 2021 to July 2023 were retrospectively analyzed. The clinical symptoms, pollen types and food allergy of the patients were analyzed by questionnaire survey and serum specific IgE detection. phi coefficient, Apriori algorithm modeling and multivariate logistic regression analysis were used to evaluate the association between allergen and symptom severity. Results:Artemisia pollen was the most common allergen in this area, with a positive rate of 96.39%. Peach and mango were the most common food allergens, which caused allergic reactions in 24.10% and 22.89% of patients, respectively. Oral mucosal symptoms were the main symptoms. Correlation analysis showed that there was a correlation between pollen allergens and allergenic food. Association rule analysis showed that when the patient was allergic to the combination of peanuts and trees, the probability of high severity of symptoms was 82.35%. Multivariate analysis showed that ragweed allergy was significantly positively correlated with the severity of PFAS symptoms. Conclusion:Artemisia pollen and related food allergens play an important role in the pathogenesis of PFAS. Association rule mining and network map analysis revealed direct associations between peanut and tree combination allergy and symptom severity, as well as potential links between other inhaled allergens and specific food allergies. Ragweed and peach allergy are independent risk factors for the aggravation of PFAS symptoms, which can be used as early warning indicators. These results help to improve the screening of high-risk patients and the construction of regional allergen databases.

Peptide-based radiopharmaceuticals targeting integrin α5β1 show promise for precise tumor diagnosis and treatment. However, current peptide-based radioligands that target α5β1 demonstrate inadequate in vivo performance owing to limited tumor retention. The use of PEGylation to enhance the tumor retention of radiopharmaceuticals by prolonging blood circulation time poses a risk of increased blood toxicity. Therefore, a PEGylation strategy that boosts tumor retention while minimizing blood circulation time is urgently needed. Here, we developed a PEGylation-enabled peptide multidisplay platform (PEGibody) for PR_b, an α5β1 targeting peptide. PEGibody generation involved PEGylation and self-assembly. [⁶⁴Cu]QM-2303 PEGibodies displayed spherical nanoparticles ranging from 100 to 200 nm in diameter. Compared with non-PEGylated radioligands, [⁶⁴Cu]QM-2303 demonstrated enhanced tumor retention time due to increased binding affinity and stability. Importantly, the biodistribution analysis confirmed rapid clearance of [⁶⁴Cu]QM-2303 from the bloodstream. Administration of a single dose of [¹⁷⁷Lu]QM-2303 led to robust antitumor efficacy. Furthermore, [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 exhibited low hematological and organ toxicity in both healthy and tumor-bearing mice. Therefore, this study presents a PEGibody-based radiotheranostic approach that enhances tumor retention time and provides long-lasting antitumor effects without prolonging blood circulation lifetime. The PEGibody-based radiopharmaceutical [⁶⁴Cu]/[¹⁷⁷Lu]QM-2303 shows great potential for positron emission tomography imaging-guided targeted radionuclide therapy for α5β1-overexpressing tumors.

Objective:To explore the distribution of allergen-specific IgE (sIgE) for children with atopic dermatitis in Tianjin City and provide the evidences of clinical diagnosis and treatment.Methods:A retrospective cross-sectional study was conducted to analyze the children who were suspected of atopic dermatitis and tested for serum sIgE in the Tianjin Children′s Hospital from March 2021 to February 2023. Using first detection results only, a total of 1 841 serum samples were tested for twenty common allergens. The method was the enzyme-linked immune capture assay. The allergen epidemiological characteristics were statistically analyzed by Chi square test based on the children′s characteristics and factors such as different sexes, ages and seasons by the mass data.Results:Among the 1 841 cases, the results showed that 1 247 (67.73%) were sensitized to at least 1 allergen-sIgE, comprising to 49.86% (918/1 841) to food allergen-sIgE and 47.96% (883/1 841) to aeroallergen-sIgE. The top three food allergens-sIgE were egg 32.10% (591/1 841), milk 25.91% (477/1 841) and wheat flour 14.61% (269/1 841); the top three positive rates of aeroallergens-sIgE were house dust 24.33% (448/1 841), alternaria 20.59% (379/1 841) and dermatophagoides farinae 14.83% (273/1 841). The positive rates of food allergens-sIgE were the highest in the 1-3 years old group (64.11%, 434/677) ( χ2=122.854, P<0.001), while the positive rates of aeroallergens-sIgE were higher in the 11-14 years old group (71.26%, 62/87) ( χ2=134.968, P<0.001). No seasonal difference was revealed in the overall positive rate of food allergen-sIgE and aeroallergen-sIgE ( χ2=4.047, P=0.256; χ2=7.549, P=0.056). The positive rates of soybean-sIgE and milk-sIgE were the highest in summer ( χ2=11.329, P=0.010; χ2=28.720 , P<0.001), whereas alternaria-sIgE and mugwort-sIgE were the highest in summer and autumn, respectively ( χ2=8.462, P=0.037; χ2=10.641 , P=0.014). Among the 1 841 cases, 32.21% were sensitized to three or more allergens-sIgE. The sIgE concentration levels of egg, milk and house dust were mainly level 1 to 2, and the proportions of level 3 and above were all under 15%; although the positive rates of crab, shrimp, and peanut were low, the proportions of grade 3 and above were all beyond 30%. Children sensitized to alternaria, dermatophagoides farinae, mugwort, and cat dander had higher sIgE concentration levels, which were 68.07%, 49.45%, 56.57% and 47.83% respectively. Conclusions:This study can reflect the epidemic characteristics of allergen-sIgE in children with atopic dermatitis in Tianjin region to a certain extent. Allergen-sIgE positivity in patients differed by age, and there were seasonal differences and grade distribution differences in the positive rates of some allergens-sIgE. It is necessary to reasonably avoid the high-risk allergens according to the epidemiological characteristics and clinical symptoms, which provide valuable information for the prevention, diagnosis and treatment of atopic dermatitis.

The relationship between the duration of type 2 diabetes mellitus (T2DM) and the risk of female reproductive malignancies is complex and multifaceted. Large population cohort studies revealed a negative association between the duration of T2DM and the incidence of breast cancer and endometrial cancer. Furthermore, the risk of breast and endometrial cancer is the highest within a short time after T2DM diagnosis and remains remarkably higher in patients with longer diabetes duration than in the nondiabetic population. This phenomenon suggests causal reverse bias and potential detection bias. Nevertheless, T2DM remains an important risk factor for breast and endometrial cancer. Research on the association between diabetes with cervical and ovarian cancer is limited, and results vary by region. Future epidemiological studies should focus on large prospective studies with long follow-up to further investigate this association. Research into the biological mechanisms linking diabetes and female reproductive cancers is also necessary to develop effective cancer prevention and early intervention strategies.

Objective To observe the inter-observer consistency of diameter of inferior vena cava(IVC)and IVC collapsibility index(IVCCI)measured and assessed with echocardiography and the correlations with right heart parameters in patients with right heart dysfunction.Methods Forty-seven patients with right heart dysfunction were prospectively recruited in observation group,while 50 adults with normal right heart function were taken as controls(control group).Parameters of the right heart were obtained with echocardiography,including the right ventricular fractional area change(FAC),the tricuspid annular plane systolic excursion(TAPSE),the myocardial performance index(MPI),the tricuspid annular systolic velocity(S')as well as early and late diastolic velocity(e',a')and e'/a' ratio,also the tricuspid valve orifice early and late diastolic velocities(E,A)and E/A ratio and E/e',the vena contracta width of tricuspid regurgitation(TR-VCW),the maximum velocity of tricuspid regurgitation(TR-Vmax),the pulmonary artery systolic pressure(PASP)and right atrial area(RAA).Besides,the maximal and minimal diameter of IVC(IVCDmax,IVCDmin)during the respiratory cycle were measured with two dimensional(2D)ultrasound and anatomical M-mode ultrasound,respectively,and the IVCCI were calculated.Then 20 subjects were randomly selected from each group,and IVC parameters were obtained.The basic data,right heart parameters and IVC parameters were compared between groups,intra-class correlation coefficient(ICC)between 2 sonographers of IVC parameters were calculated,and correlations between IVC parameters and right heart parameters were assessed.Results No significant differences of gender,age nor body mass index(BMI)was detected between groups(all P＞0.05).Compared with those in control group,MPI,e',e'/a',E,A,E/e',TR-VCW,TR-Vmax,PASP and RAA increased,whereas FAC,TAPSE,S'and a'decreased in observation group(all P＜0.05).The inter-observer consistencies were good for IVCDmax and IVCCI in observation group(ICC=0.787-0.971)and IVCDmax in the control group(ICC=0.971,0.964)obtained with 2D ultrasound and anatomical M-mode ultrasound,but poor for IVCCI in control group(ICC=0.169,0.456).Compared with those in control group,IVC parameters 2D-IVCDmax,2D-IVCDmin,M-IVCDmax and M-IVCDmin increased but 2D-IVCCI and M-IVCCI decreased in observation group(all P＜0.05).In control group,2D-IVCDmax was weakly negatively correlated with TAPSE and a'(r=-0.392,-0.364),weakly positively correlated with e'/a',E,E/A,TR-VCW and RAA(r=0.396,0.483,0.461,0.565,0.582),2D-IVCCI was weakly negatively correlated with TR-VCW and RAA(r=-0.386,-0.380),while M-IVCDmax was weakly negatively correlated with TAPSE(r=-0.384),and weakly positively correlated with e'/a',E,E/A,TR-VCW and RAA(r=0.357,0.453,0.473,0.549,0.550),M-IVCCI was weakly negatively correlated with MPI,E,TR-VCW and RAA(r=-0.347,-0.337,-0.475,-0.421).Conclusion In patients with right heart dysfunction,IVCD diameter and IVCCI obtained with echocardiography had good inter-observer consistencies.Parameters obtained with 2D ultrasound and anatomic M-mode ultrasound had certain relations with the right heart parameters.

Objective:To investigate the application value of intraoperative motor nerve monitoring in cervical neurogenic tumor surgery.Methods:The efficacy of intraoperative neuromonitoring (IONM) was analyzed retrospectively in 18 patients, including 6 males and 12 females, aged from 15 to 74 years, treated in Affiliated Drum Tower Hospital, Medical School of Nanjing University from June 2019 to September 2022 who underwent total cystectomy of cervical neurogenic tumors under intraoperative nerve monitoring.Results:All 18 patients had complete tumor removal, including 8 patients with tumors from the vagus nerve and 10 patients with tumors from the brachial plexus nerve. Postoperative nerve functions were normal in patients with tumors from brachial plexus nerve, and incomplete vocal cord paralysis occurred in 2 patients with tumors from vagus vagus nerve. The total incidence of motor nerve injury was 11.1% (2/18). All patients were followed up for 6 to 45 months, with no tumor recurrence.Conclusion:Intraoperative neuromonitoring has significant values in surgery of cervical neurogenic tumors, which is helpful to remove completely the tumors on the basis of protecting the nerve functions to the maximum extent.
