Objective:To conduct a survey on the influence of personality trait on depres-sive symptom and obesity in patients before bariatric and metabolic surgery.Methods:The retros-pective cross-sectional investigation study was conducted. Patients who underwent bariatric and metabolic surgery in The Third Xiangya Hospital of Central South University and The First Affiliated Hospital of Ji′nan University from January 1 to June 1,2024 were recruited. The survey was conducted in electronic format using the general information survey questionnaire, the patient health question-naire-9 (PHQ-9), and the Chinese big five personality inventory brief version (CBF-PI-B). Observa-tion indicators: (1) results of the questionnaire; (2) general data of patient; (3) personality trait scores for patient with different subtypes of obesity; (4) depression symptom scores for patient with different subtypes of obesity; (5) correlation analysis for patient personality trait, depressive symptom and body mass index (BMI). Comparison of measurement data with normal distribution between groups was conducted using the independent t test, and one-way analysis of variance was used for comparison among multiple groups. LSD test was used for pairwise comparison. Comparison of measurement data with skewed distribution among multiple groups was conducted using the Kruskal-Wallis H test, and Dunn Bonferroni test was used for pairwise comparison. The Spearman correlation analysis and Pearson correlation analysis were used for correlation analysis, and the mediation effect analysis was conducted using the Process 4.0 model and the Bootstrap test. Results:(1)Results of the questionnaire. A total of 146 questionnaires were distributed and collected, including 83 questionnaires from The Third Xiangya Hospital of Central South University and 63 questionnaires from The First Affiliated Hospital of Ji′nan University. Of 146 questionnaires, 137 questionnaires were valid, yielding an effective response rate of 93.836%(137/146). (2)General data of patient.

Conclusion:Preoperative personality trait of patients undergoing bariatric and metabolic surgery can influence their depressive symptom and BMI.

Systemic sclerosis is an autoimmune rheumatic disease that often leads to multisystem diseases,frequently resulting in pulmonary interstitial fibrosis.According to the theory of sanjiao(triple energizers)membranous channels,sanjiao connects the five zang-organs and six fu-viscera internally and the skin,muscles,and bones externally.It serves as a four-way membranous channel that connects internal organs and external structures,linking with the micromembranes of organs and blood vessels.The pathogenesis of pulmonary interstitial fibrosis secondary to systemic sclerosis involves external cold obstructing the skin and interstitial layers,impairing the defense qi and defense yang,which originate in the essence of the kidney.This leads to weak defensive qi and kidney deficiency,causing stagnation in sanjiao's energy flow and disruption of water and gasification and loss of fluid,resulting in accumulation of dampness,phlegm,and blood stasis.These obstructive factors spread along sanjiao's membranous channels,leading to multiorgan micromembrane involvement and systemic damage.The lungs,which are in direct contact with the external environment,are particularly susceptible to invasion by external pathogens.When combined with stagnation of dampness,phlegm,and blood in the lungs,this leads to secondary pulmonary fibrosis,resulting in lung dysfunction.Continuous stagnation of sanjiao exacerbates the overall condition of the patient,leading to a mixed cold-heat imbalance.Treatment focuses on"unblocking,transforming,and regulating"to restore sanjiao function,promote qi and fluid circulation,invigorate blood,and adjust the cold-heat imbalance,ultimately restoring the overall condition of the patient.

Objective:To investigate the role of ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) in renal tubular epithelial-mesenchymal transition (EMT) in diabetic nephropathy (DN).Methods:Renal tissue specimens from 24 DN patients (DN group) confirmed by medical history, clinical laboratory tests, and pathological diagnosis at the Third Hospital of Hebei Medical University and 15 adjacent normal renal tissues (control group) from 2018 to 2023 were collected. Immunohistochemical staining was performed to detect the expression of EBP50, E-cadherin, and Vimentin proteins. Additionally, 10 healthy volunteers were enrolled as a normal group, and fasting blood glucose, serum creatinine, blood urea nitrogen, and 24 h urinary protein levels were compared between DN patients and the normal group.Results:Fasting blood glucose, serum creatinine, blood urea nitrogen, and 24 h urinary protein levels were significantly higher in the DN group than in the normal group (all P<0.01). Periodic acid-schiff (PAS) staining revealed significant thickening of the glomerular basement membrane, increased extracellular matrix, vacuolar degeneration of renal tubules, and elevated extracellular matrix in the renal interstitium in the DN group. Immunohistochemistry showed higher expression of EBP50 and E-cadherin proteins in the control group than in the DN group (all P<0.01), while Vimentin expression was lower in the control group ( P<0.01). Conclusions:EBP50 is involved in the EMT process of renal tubules in DN and is associated with tubular injury.

The classification of stoma skin barriers varies based on their specific features. The curvature design of convex skin barriers provides a secure and effective seal for patients with flat, retracted stomas or peristomal skin folds. The secure sealing ability of convex skin barriers is attributed to several critical structural components. Although convex skin barriers offer many clinical advantages, there is currently no unified standard for measuring their characteristics, resulting in confusion among healthcare professionals when selecting stoma care products. To address this issue, the 2021 International Stoma Care Expert Meeting proposed the Expert Consensus on Characteristics of Convex Skin Barriers and Clinical Application, which clearly defines five essential properties and clinical application guidelines for convex barriers. However, as most consensus contributors are from Europe and North America, its applicability in Chinese healthcare settings may be limited. Therefore, this paper provides a detailed interpretation of the five characteristics and clinical application statements of convex skin barriers, aiming to offer practical guidance to clinical nurses in selecting appropriate convex products and managing stoma-related complications.

Objective To investigate the relationship between triglyceride glucose body mass index(TyG-BMI),high density lipoprotein cholesterol to Apolipoprotein A ratio(HAR),glycemic risk index(GRI)and diabetic retinopathy(DR).Methods A total of 159 patients with type 2 diabetes mellitus(T2DM)complicated with DR(the DR group)were divided into the non-proliferative retinopathy group(NPDR group,66 cases)and the proliferative retinopathy group(PDR group,93 cases)according to DR international clinical grading criteria,and 159 T2DM patients without DR were selected as the control group.Clinical information and baseline laboratory test results were recorded,and TyG-BMI,HAR and GRI were calculated.Multivariate Logistic regression analysis was conducted to analyze the related factors of the incidence of DR,and receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of TyG-BMI,HAR and GRI for DR.Results The duration of T2DM,the proportion of hypertension,diabetic nephropathy and diabetic foot,levels of HbA1c,homeostasis model insulin resistance index(HOMA-IR),total cholesterol(TC),C-reactive protein(CRP),TyG-BMI,HAR and GRI were higher in the DR group than those in the control group(P<0.05).TyG-BMI,HAR and GRI were higher in the PDR group than those in the NPDR group(P<0.05).Multivariate Logistic regression analysis showed that the longer course of T2DM disease[OR(95%CI):2.781(1.398-5.534)],high TyG-BMI[2.036(1.169-3.546)],high HAR[1.890(1.090-3.280)]and high GRI[1.836(1.065-3.167)]were risk factors for DR(P<0.05).ROC curve analysis results showed that,the area under the curve(AUC)of combined TyG-BMI,HAR and GRI diagnosis of DR was higher than that of single diagnosis[0.940(0.908-0.964),0.864(0.821-0.900),0.796(0.747-0.839)and 0.836(0.790-0.875),all P<0.05].Conclusion The increased TyG-BMI,HAR and GRI in T2DM patients is associated with the onset and severity of DR,and which can be used to assess the risk of DR.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Objective:To construct a sizeable naive human Fab phage display antibody library to screen high-affinity specific antibodies in vitro. Methods:Total RNA was extracted from peripheral blood mononuclear cells (PBMCs) of 126 healthy individuals, subsequently reverse-transcribed into cDNA, and used as a template. PCR amplification was performed to obtain the V H from IgG, IgM and light chain κ, λ, separately, with the initial PCR products serving as templates for a second round of PCR. Overlap extension PCR was employed to generate fragments of the κ and λ light chains. These fragments were ligated with the phage vector pNC3, which harbors the variable region 1 of the heavy chain, to construct a recombinant phage plasmid. This plasmid was then electroporated into competent Escherichia Coli TG1 cells to establish a naive human Fab phage display antibody library. One hundred clones were randomly selected for identification and sequencing, and antibody gene polymorphisms were analyzed using the IMGT database and MAFFT software. Recombinant α-hemolysin from Staphylococcus aureus was utilized to screen Fab antibody fragments through biopanning of the antibody library, followed by random selection of phage ELISA-identified clones. The positive clones (antigen A450∶blank control A450≥2.1) were sequenced. Results:Two large naive Fab phage display antibody libraries were successfully constructed, in which the capacity of κ and λ chain antibody libraries were 1.25×10 11 and 1.54×10 11, respectively. The titers for two antibody libraries were 6.04×10 13 CFU/ml and 3.50×10 13 CFU/ml. The positive transformation insertion rates for κ and λ chain antibody libraries were 96% (96/100) and 100% (100/100), respectively. Sequence analysis revealed that all antibody sequences were unique. The amino acid sequences in the skeletal region were relatively conserved. In contrast, significant variations in the length of the complementarity determining region (CDR) were found, and the diversity of amino acid sequence of the complementary determining region was high, especially the CDR3. Analysis using the IMGT database indicated that the sequences exhibited a broad distribution across variable-diversity-joining gene families. After six rounds of panning, specific phage antibodies enrichment targeting α-hemolysin were achieved. A total of 142 monoclonal antibodies were sequenced, yielding 8 distinct Fab antibody sequences. Conclusion:This study successfully constructed two naive human Fab phage display antibody libraries with large capacity and good diversity, which can be used for screening human antibodies for serum epidemiology.
