Background::The increasing incidence of inflammatory bowel disease (IBD) presents significant medical and societal challenges. A well-designed IBD database is crucial for both epidemiological studies and clinical management. However, inconsistencies between regional databases hinder cross-institutional and international research, especially between Eastern and Western societies.Methods::We developed a new IBD database, the 301 IBD database, integrating the IBD clinical characteristics from the Penn IBD database (USA) and the latest IBD guidelines and consensus and clinical practices of the Chinese PLA General Hospital (PLAGH). We applied this database to analyze clinical data of IBD inpatients at PLAGH from 2008 to 2023.Results::The 301 IBD database contains 490 items in 6 sections including demographic characteristics, personal history, clinical phenotype, disease activity, laboratory tests and examinations, and treatment. Features of the 301 IBD database include inpatient focus, biochemical indicators and opportunistic infection focus, and more about ulcerative colitis (UC)-associated complications. Single-center analysis revealed an increasing hospitalization trend, from 2.35% in 2008 to 3.94% in 2023. We found that the clinical characteristics of our UC inpatients are predominantly male (62.5%), extensive lesions (55.1%), low usage of biologics (4.1%), and a high incidence of UC-CRC (3.0%). The clinical characteristics of CD inpatients included male predominance (68.39%), early onset age (35.43 ± 14.75-year-old), and high rate of surgery (25.81%).Conclusion::The 301 IBD database, integrating Eastern and Western clinical data, provides a valuable tool for IBD clinical research. Future international, multicenter collaborations are expected to further enhance its utility.

Objective:To investigate the relationship between the serum levels of vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9), S100 calcium binding protein B (S100B) with glycolipid metabolism, pregnancy outcome in pregnant women with gestational diabetes.Methods:The clinical data of 153 pregnant women with gestational diabetes (research group) and 153 healthy pregnant women (control group) in the Second Affiliated Hospital of Xi ′an Medical University from January 2020 to October 2023 were retrospectively analyzed. The serum levels of VEGF, MMP-9 and S100B were measured by enzyme linked immunosorbent assay, and the fasting blood glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting insulin and glycated hemoglobin were measured, and the homeostasis model assessment insulin resistance index (HOMA-IR) was calculated. The adverse outcomes of pregnant women with gestational diabetes were recorded. Pearson method was used to analyze the correlation between glycolipid metabolism indexes and VEGF, MMP-9, S100B in pregnant women with gestational diabetes. Multivariate Logistic regression was used to analyze the independent risk factors of adverse pregnancy outcome in pregnant women with gestational diabetes. Receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of VEGF, MMP-9 and S100B on adverse pregnancy outcome in pregnant women with gestational diabetes. Results:The fasting blood glucose, fasting insulin, glycated hemoglobin, HOMA-IR, triglyceride, total cholesterol, LDL-C, VEGF, MMP-9 and S100B in research group were significantly higher than those in control group: (9.42 ± 0.65) mmol/L vs. (4.13 ± 0.46) mmol/L, (16.58 ± 2.37) mU/L vs. (13.41 ± 2.05) mU/L, (7.28 ± 0.46)% vs. (4.35 ± 0.39)%, 4.83 ± 0.42 vs. 2.71 ± 0.37, (3.41 ± 0.67) mmol/L vs. (2.85 ± 0.63) mmol/L, (5.54 ± 1.56) mmol/L vs. (5.12 ± 1.50) mmol/L, (3.14 ± 0.97) mmol/L vs. (2.86 ± 0.93) mmol/L, (184.02 ± 30.25) ng/L vs. (156.33 ± 26.41) ng/L, (45.78 ± 7.56) μg/L vs. (29.36 ± 5.03) μg/L and (117.51 ± 25.12) ng/L vs. (89.74 ± 22.46) ng/L, the HDL-C was significantly lower than that in control group: (1.34 ± 0.27) mmol/L vs. (1.42 ± 0.30) mmol/L, and there were statistical differences ( P<0.01 or <0.05). Pearson correlation analysis result showed that VEGF, MMP-9, S100B in pregnant women with gestational diabetes were positively correlated with fasting blood glucose, fasting insulin, glycated hemoglobin, HOMA-IR, triglyceride, total cholesterol and LDL-C ( P<0.01), negatively correlated with HDL-C ( P<0.01). Among 153 pregnant women with gestational diabetes, 49 had adverse pregnancy outcome, and 104 had good pregnancy outcome. The VEGF, MMP-9 and S100B in pregnant women with adverse pregnancy outcome were significantly higher than those in pregnant women with good pregnancy outcome: (212.75 ± 28.63) ng/L vs. (170.49 ± 26.58) ng/L, (52.37 ± 7.14) μg/L vs. (42.68 ± 6.35) μg/L and (136.83 ± 23.62) ng/L vs. (108.41 ± 21.35) ng/L, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that VEGF, MMP-9 and S100B were independent risk factors for adverse pregnancy outcome in pregnant women with gestational diabetes ( OR = 7.013, 5.382 and 6.129; 95% CI 5.206 to 9.447, 3.449 to 8.398 and 3.520 to 10.673; P<0.01). ROC curve analysis result showed that the area under the curve of VEGF, MMP-9 combined S100B in predicting adverse pregnancy outcome in pregnant women with gestational diabetes was significantly larger than that of VEGF, MMP-9 and S100B alone (0.945 vs. 0.863, 0.847 and 0.801; P<0.05 or <0.01), with sensitivity of 89.80% and specificity of 91.30%. Conclusions:The high serum levels of VEGF, MMP-9 and S100B are associated with abnormal glycolipid metabolism and adverse pregnancy outcome in pregnant women with gestational diabetes, and the combination of the three indexes has a high predictive value for adverse pregnancy outcome.

Objective To investigate the correlation between serum plasma membrane vesicle-associated protein (PLVAP) levels and metabolism-associated fatty liver disease (MAFLD) in patients with T2DM. Methods Atotal of 255 patients with type 2 diabetes mellitus (T2DM) went to Gansu Provincial Hospital from September 2023 to March 2024 were selected in this study,and were divided into T2DM alone group (n=141) and the T2DM combined with MAFLD group (n=114) according to whether they were combined with MAFLD or not.Spearman correlation analysis was used to analyze the correlation between serum PLVAP and other indexes,multiple linear regression analysis was used to analyze the influencing factors of serum PLVAP,and Logistic regression analysis was used to analyze the influencing factors of MAFLD in T2DM patients. The early diagnostic value of serum PLVAP on MAFLD in patients with T2DM by analyzing the receiver's operating characteristics (ROC) curve. Results Compared with the MAFLD group,BMI,WC,FPG,C-P,HOMA-IR,TG,AST,ALT,GGT,hepatic steatosis index (HSI) and phytohaemagglutinin-like oxidized low-density lipoprotein receptor 1 (LOX-1) were decreased in the T2DM group (P<0.05).DM duration,HDL-C,AST/ALT and PLVAP were elevated (P<0.05). Spearman correlation analysis showed that PLVAP was positively correlated with AST/ALT (P<0.05) and negatively correlated with WC,DBP,C-P,ALT,GGT and HSI (P<0.05). Multiple linear regression analysis showed that WC was an influencing factor for PLVAP.Logistic regression analysis showed that DM duration,WC,TG,PLVAP,LOX-1 were influencing factors for MAFLD. Analysis of the subjects' work characteristics (ROC) curve showed that the area under the ROC curve was 0.785,with a sensitivity of 81.6％ and a specificity of 67.4％. Conclusions Reduced PLVAP is a risk factor for comorbid MAFLD in patients with T2DM and is important for predicting the co-existence of MAFLD in patients with T2DM.

Objective:To compare the value of 3 methods (threshold method, visual method and CT method) based on 18F-FDG PET-CT for qualitative diagnosis of solitary pulmonary nodules (SPN). Methods:The clinical characteristics, pathological results, CT signs and maximum standardized uptake value (SUV max) of 226 SPN patients who underwent 18F-FDG PET-CT and met lung imaging reporting and data system (Lung-RADS1.1) grading criteria grade 2-4 in Shanxi Province Cancer Hospital from January 2015 to January 2019 were retrospectively analyzed, and the diagnostic efficacy of threshold method (according to SUV max), visual method [according to the degree of fluorodeoxyglucose (FDG) uptake in the mediastinum or liver blood pool] and CT method (according to Lung-RADS1.1 grading criteria) for SPN were compared by using receiver operating characteristic (ROC) curve. The highest diagnostic accuracy of CT method and the highest diagnostic accuracy of threshold method and visual method were combined as PET-CT comprehensive diagnosis method, and the diagnostic efficiency of which was compared with the other methods. Results:Among the 226 patients with SPN, 174 cases were malignant and 52 cases were benign in pathology. ROC curve analysis showed that the area under the curve (AUC) of CT method 2 (defined Lung-RADS1.1 grade 4A and below as benign, grade 4B and above as malignant) in CT methods for qualitative diagnosis of SPN was 0.622, the sensitivity was 87.93%, and the accuracy was 76.11%, the diagnostic efficiency was higher than method 2. The AUC of the threshold method 1 (defined solid nodules that SUV max≥2.5 and ground-glass nodules that SUV max≥1.14 as malignant, the others as benign) in threshold methods for qualitative diagnosis of SPN was 0.675, the sensitivity was 85.06%, and the accuracy was 76.99%, the diagnostic efficiency was higher than other methods in the threshold methods and visual methods. The AUC of PET-CT comprehensive diagnosis method (combination of CT method 2 and threshold method 1) for qualitative diagnosis of SPN was 0.652, the sensitivity was 97.70%, and the accuracy was 82.74%, the diagnostic efficiency was higher than other methods. Conclusions:There is no significant difference among threshold method, visual method and CT method based on 18F-FDG PET-CT in qualitative diagnosis of SPN. The diagnostic efficiency of combining CT method with threshold method is significantly improved.

Nutrition therapy is considered as the basis for prevention and management of chronic kidney disease (CKD), throughout the three-tier prevention strategies of CKD. The primary objective is to delay the disease progression, correct metabolic disorders, and improve the outcomes of CKD. Low protein diet has been recognized as an important therapeutic measure in CKD, but the quantity, quality and source of protein are always the points of contention. Recently, both domestic and foreign guidelines have been updated on the amount of protein intake. In addition to quantity, attention has been paid to the type and diversity of proteins. With the rise of plant-based food consumption and the concept of vegetarian diet, the scientific community began to review the benefits of plant protein again, and a plant-based diet is recommend extensively. Whether the plant-based dietary pattern is also suitable for CKD patients who need a low-protein diet, and whether it could meet the nutritional needs of CKD patients are hot topics, this article reviews the recent progress of these research hotspots.

Objective:To investigate the turnover intention and its influencing factors in rural general practitioners in southwest Shandong province.Methods:In May 2020, a survey with self-designed questionnaire was conducted among 2 805 rural general practitioners in southwest Shandong province selected by multi-stage sampling method. Pearson chi square test (χ2) and binary logistic regression were used to analyze the factors influencing the turnover intention of rural general practitioners.Results:A total of 2 805 questionnaires were sent out, 2 693 were collected and 2 272 were valid, with an effective rate of 84.4%. Among 2 272 participants, 1 076 (47.4%) had medium to high level turnover intention. Binary logistic regression showed that part-time job ( OR=1.443, 95% CI: 1.105-1.884, P<0.01), average monthly night shifts ≥20 times ( OR=1.340, 95% CI: 1.106-1.623, P<0.01), daily working time ≥13 hours ( OR=1.358, 95% CI: 1.107-1.666, P<0.01), insomnia ( OR=2.075, 95% CI: 1.755-2.454, P<0.01), feeling depressed at work ( OR=2.987, 95% CI: 2.516-3.546, P<0.01), degree of emotional exhaustion ( OR=3.801, 95% CI: 3.188-4.533, P<0.01) and degree of de-personalization tendencies ( OR=2.493, 95% CI: 2.086-2.981, P<0.01) were the significant factors influencing the turnover intention of rural general practitioners. Conclusions:Rural general practitioners in southwest Shandong have a high-level turnover intention, part-time jobs, average number of night shift per month, working time, insomnia, depression and job burnout are the main factors affecting the turnover intention. Necessary measures should be taken by relevant departments to enhance the stability of rural general practitioners.

Objective To investigate the impact of secreted frizzled-related protein 1 (SFRP 1) gene polymorphisms and gene-smoking interactions on the risk of large artery atherosclerotic (LAA) stroke.Methods Two hundred and sixty-four patients diagnosed with LAA stroke and 228 healthy controls were enrolled from the Department of Neurology,Affiliated Hospital of Qingdao University from August 2016 to June 2017.The methods of polymerase chain reaction-restriction fragment length polymorphism,combined with DNA sequencing,were used to detect the three single nucleotide polymorphisms (SNPs:rs7832767,rs1127379,rs3242) in the SFRP 1 gene.Logistic regression was applied to analyze associations between SNPs and LAA stroke.Cross analysis of additive model was used to evaluate gene-smoking interactions.Results The genotype TT/CT and allele T of rs7832767 in case group were in higher frequency than that in controls (54.9％ (145/264) vs 37.7％ (86/228),OR =2.123,95％ CI 1.482-3.041,P ＜0.01;33.9％ (179/528) vs 20.0％ (91/456),OR=2.057,95％ CI 1.536-2.755,P＜ 0.01).However,the frequencies of genotypes and alleles in other SNPs (rs1127379,rs3242) showed no significant differences between cases and controls.Multivariate Logistic regression analysis showed that TT/CT genotype was a risk factor for LAA stroke (OR =1.649,95％ CI 1.066-2.550.P =0.025).Moreover.SFRP 1 gene was not related to the distribution of cerebralvascular stenosis in LAA stroke patients.Additive model analysis showed significant interactions between rs7832767 and smoking (relative excess risk of interaction =2.442,95％ CI 0.281-4.603).Smokers with T allele of rs7832767 showed significantly increased risk of LAA stroke (OR =3.252,95％ CI 1.629-6.491,P =0.001).Whereas,no significant interaction was detected between rs3242 or rs1127379 and smoking.Conclusion The T allele of rs7832767 within SFRP 1 gene may be a risk factor of LAA stroke,and the interactions between rs7832767 and smoking can significantly increase the risk of LAA stroke.
