OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective : To investigate the changes of lipid biomarkers and lipid metabolic pathways related to liver injury in BTBR ob/ob mice with type 2 diabetes mellitus by biochemical and metabolomics methods． Methods : 16 BTBR wild-type (WT) mice (WT group) and 14 BTBR ob/ob obese mice (ob / ob group) at 7 weeks of age were selected and fed in SPF environment until 20 weeks of age．Liver injury was compared between the two groups : The activities of mitochondrial respiratory enzyme complex in liver tissue were detected by high-resolution respirators，and the lipid metabolomic analysis of liver tissue samples in the two groups of mice was performed by ultra-perform- ance liquid chromatography-quadrupole time-of-flight mass spectrometry，mainly detecting endogenous metabolites. Principal component analysis (PCA) ，orthogonal partial least squares discriminant analysis ( OPLS-DA) and other models were used to screen potential biomarkers，and the metabolic pathway analysis of the identified metabolites was performed by MetaboAnalyst 5. 0 . Results : Compared with the WT group，the ob / ob group had significantly increased body weight，fasting blood glucose ，serum levels of aspartate aminotransferase ( AST) ，alanine amin- otransferase (ALT) ，low-density lipoprotein (LDL-C) and cholesterol ( CHO) (P＜0. 01) ．Liver hematoxylin-eo- sin staining (HE) staining showed that the mice in ob / ob group had structural disorder of liver lobules，swelling of liver cells ，a large number of fat vacuoles in cells ，diffuse distribution and loose cytoplasm． Oil red O staining showed that there was a large amount of lipid deposition in the hepatocytes ofob/ob mice．The high resolution spi- rometer showed that the ob/ob mice had mitochondrial oxidative phosphorylation disorder and the activity of complex Ⅳ decreased．Lipid metabolomic analysis showed that the lipid metabolic profile of ob/ob mice changed，and the metabolic pathways involved mainly included glycerophospholipid metabolism，glycosylphosphatidylinositol ( GPI) anchor biosynthesis，triglyceride metabolism，linoleic acid metabolism，α-linolenic acid metabolism and arachidon- ic acid metabolism． Conclusion The liver injury of ob / ob group mice may be related to the disorder of lipid me- tabolism，in which the disorder of glycerophospholipid metabolism is the most critical metabolic pathway.

Objective:To detect the prevalence of mosaic loss of chromosome Y in adult men in ten study areas in China, describe the epidemiological distribution of mosaic loss of chromosome Y (mLOY) carriers and assess its prospective association with lung cancer.Methods:Based on the data from baseline survey, genetic analysis and follow-up (as of December 31, 2018) from China Kadoorie Biobank, we used Mosaic Chromosomal Alterations pipeline to detect mLOY carriers in 10 areas in China and described the epidemiological characteristics of mLOY carriers in adult men, including age, area distribution, lifestyle and disease history. We used multivariate logistic regression model to identify the potential relevant factor of mLOY. Cox proportional hazard regression model was fitted to assess the prospective association of mLOY with lung cancer. Stratification analysis were conducted to evaluate the potential modification effects of smoking and age. We also conducted mediation analysis to assess the mediating effect of mLOY in the association between smoking and lung cancer.Results:A total of 42 859 adult men were included in our analysis, in whom 2 458 mLOY carriers were detected (5.7%). The detection rate increased with age ( P<0.05). The detection rate was higher in urban area (7.3%±0.2%) than that in rural area (4.7%±0.1%). The results of logistic regression analysis indicated that smoking might be a risk factor for the detection of mLOY ( OR=1.49, 95% CI:1.36-1.64). After follow-up for average 11.1 years, 1 041 lung cancer cases were observed. The prospective analysis showed that mLOY carriers had an increased risk for lung cancer by 24% compared with non-mLOY carriers ( HR=1.24, 95% CI:1.01-1.52) and expanded mLOY carriers (mLOY cell proportion ≥10%) had an increased risk for lung cancer by 50% ( HR=1.50, 95% CI:1.13-2.00). Stratification analysis showed no modification effects of smoking and age in the association between mLOY and lung cancer (interaction P>0.05). Mediation analysis showed that mLOY could be a mediating factor in the association between smoking and lung cancer, the estimated effect was 0.09 (0.01-0.17). Conclusions:There were significant differences in the detection rate of mLOY in adult men with different social-economic characteristics and lifestyles in ten areas in China. Besides, mLOY carriers, especially expanded mLOY carriers, had increased risk for lung cancer and mLOY might be a mediating factor in the association between smoking and lung cancer.

Objective:To investigate the value of an MRI and digital pathology images based omics nomogram for the prediction of recurrence risk in soft tissue sarcoma (STS).Methods:This was a retrospective cohort study. From January 2016 to March 2021, 192 patients with STS confirmed by pathology in the Affiliated Hospital of Qingdao University were enrolled, among which 112 patients in the Laoshan campus were enrolled as training set, and 80 patients in the Shinan campus were enrolled as validation set. The patients were divided into recurrence group ( n=87) and no recurrence group ( n=105) during follow-up. The clinical and MRI features of patients were collected. The radiomics features based on fat saturated T 2WI images and pathomics features based on digital pathology images of the lesions were extracted respectively. The clinical model, radiomics model, pathomics model, radiomics-pathomics combined model, and omics nomogram which combined the optimal prediction model and the clinical model were established by multivariate Cox regression analysis. The concordance index (C index) and time-dependent area under the receiver operating characteristic curve (t-AUC) were used to evaluate the performance of each model in predicting STS postoperative recurrence. The DeLong test was used for comparison of t-AUC between every two models. The X-tile software was used to determine the cut-off value of the omics nomogram, then the patients were divided into low risk ( n=106), medium risk ( n=64), and high risk ( n=22) groups. Three groups′ cumulative recurrence-free survival (RFS) rates were calculated and compared by the Kaplan-Meier survival curve and log-rank test. Results:The performance of the radiomics-pathomics combined model was superior to the radiomics model and pathomics model, with C index of 0.727 (95% CI 0.632-0.823) and medium t-AUC value of 0.737 (95% CI0.584-0.891) in the validation set. The omics nomogram was established by combining the clinical model and the radiomics-pathomics combined model, with C index of 0.763 (95% CI 0.685-0.842) and medium t-AUC value of 0.783 (95% CI0.639-0.927) in the validation set. The t-AUC value of omics nomogram was significantly higher than that of clinical model, TNM model, radiomics model, and pathomics model in the validation set ( Z=3.33, 2.18, 2.08, 2.72, P=0.001, 0.029, 0.037, 0.007). There was no statistical difference in t-AUC between the omics nomogram and radiomics-pathomics combined model ( Z=0.70, P=0.487). In the validation set, the 1-year RFS rates of STS patients in the low, medium, and high recurrence risk groups were 92.0% (95% CI 81.5%-100%), 55.9% (95% CI 40.8%-76.6%), and 37.5% (95% CI 15.3%-91.7%). In the training and validation sets, there were statistically significant in cumulative RFS rates among the low, medium, and high groups of STS patients (training set χ2=73.90, P<0.001; validation set χ2=18.70, P<0.001). Conclusion:The omics nomogram based on MRI and digital pathology images has favorable performance for the prediction of STS recurrence risk.

Objective To explore the correlation between serum vitamin D levels,vitamin D receptor gene polymorphism,and the incidence of chronic urticaria in children,and to provide clinical evidence for screening the genetic susceptibility of chronic urticaria in children.Methods Clinical data and peripheral blood samples were collected from 100 children with chronic urticaria in the test group and 100 healthy children in the control group who were admitted to the Dermatological Department of Pingshan Distinct Maternal and Child Health Hospital from December 2021 to January 2023.Chemiluminescent assays were used to measure the levels of 25(OH)D,IgE and IgG.PCR amplification was performed to amplify the VDR gene polymorphic sites ApaI,BsmI,TaqI,FokI,and Tru9I,followed by sequencing to assess the VDR gene polymorphism and the expression levels of the associated genetic polymorphic sites rs7975232,rs1544410,rs731236,rs2228570,and rs757343.Results The levels of 25(OH)D in the test group were lower than that in the control group,while IgE and IgG levels were higher than those in the control group,and the differences were statistically sig-nificant.Multivariate logistic regression analysis showed that the T allele of rs757343 was a risk factor for the incidence of chronic urticaria in children(OR=1.45 8,95％CI:1.015-2.153,P=0.047),while the CC geno-type of rs757343 and 25(OH)D were protective factors(OR=0.250,95％CI:0.056-0.786,P=0.031;OR=0.553,95％CI:0.373-0.713,P＜0.001).ROC curve analysis showed that the area under the curve for 25(OH)D,white blood cell count,neutrophil percentage,lymphocyte percentage,and basophil percentage were 0.928,0.701,0.808,0.797 and 0.753,all＞0.7.Conclusion Vitamin D can assist in the diagnosis of uricaria in children and evaluate the progression of the disease.25(OH)D is a protective factor for the onset of chronic urticaria in children,the T allele of the VDR gene polymorphism rs757343 is a risk factor for chronic urticaria in children,while the CC genotype is a protective factor.

Objective:To summarize the preliminary experience of endoscopically assisted mid-cheek benign tumor resection using a single preauricular or transoral incision and to evaluate its indications, advantages, and disadvantages.Methods:Thirty-six patients with benign mid-cheek tumors were prospectively enrolled, including 11 males and 25 females, aged (37.2± 15.9) years and ranged from 11 to 65 years old. The patients were randomly divided into two groups: endoscope-assisted tumor dissections through a single preauricular incision (preauricular group, 19 cases) or transoral incision (transoral group, 17 cases). Their surgical approaches were introduced, and the tumor long-axis length, incision length, operative time, estimated intraoperative bleeding, postoperative drainage amount and time, aesthetic satisfaction, perioperative complications, and follow-up were recorded and analyzed.Results:The difference between the tumor long-axis lengths in the preauricular group [(2.2±0.9) cm] and the transoral group [(2.1± 0.7) cm] was not statistically significant ( t=0.46, P=0.687), and all surgical procedures were completed as planned. There was no significant difference in the incision size ( t=1.57, P=0.100) or operative time ( t=0.44, P=0.736). Compared with the preauricular group [(30.8±8.7) ml], transoral group [(23.6±8.9) ml] significantly reduced intraoperative blood loss ( t=2.97, P=0.006) and improved aesthetic pleasure ( t=3.44, P=0.015). Two cases of earlobe numbness and one case of temporary facial palsy were observed in the preauricular group; two cases of postoperative effusion were noted in the transoral group, and no signs of nerve injury were detected. No tumor recurrence was found during the 1-54-month of follow-up. Conclusions:Endoscopic-assisted preauricular or transoral incision for dissecting mid-cheek benign tumors provides excellent aesthetic and minimally invasive results, reducing complications and obtaining satisfactory aesthetic results.

Objective:To investigate the changes of ROS/TXNIP/NLRP3 signaling pathway in pyroptosis of human embryonic trophoblast cells induced by high glucose.Methods:Human embryonic trophoblast cells were cultured in vitro to establish high glucose injury model, and they were randomly divided into control group, high glucose (HG) group and HG + ROS inhibitor N-acetyl-L-cysteine (HG + NAC) group. MTT assay was used to detect the cell survival rate. The level of ROS in each group was detected by dihydroethidine ROS fluorescence probe. Expression of TXNIP and NLRP3 mRNA was detected by real-time quantitative PCR (RT-qPCR). Western blot analysis was used to detect the expression levels of TXNIP, NLRP3, Caspase-1, interleukin (IL) -1β, tumor necrosis factor-α (TNF-α) and GSDMD proteins. In addition, pyroptosis was detected by flow cytometry.Results:The optimal glucose concentration for high glucose-induced injury of human embryonic trophoblast cells was 30 mmol/L. Compared with the control group (96.27±3.10) %, the survival rate of human embryonic trophoblast cells in HG group (55.44±2.15) % was significantly lower ( P<0.05), while the fluorescence intensity (ROS level) of 7 'dichlorofluorescein (DCF), the expression levels of TXNIP and NLRP3 proteins, the number of pyroptosis, expression levels of Caspase-1, GSDMD, IL-1β and TNF-α proteins were significantly higher ( P<0.05) ; Compared with HG group, the survival rate of human embryonic trophoblast cells in HG+NAC group (84.75±2.33) % was significantly higher ( P<0.05), the fluorescence intensity (ROS level) of DCF, the expression levels of TXNIP and NLRP3 proteins, the number of pyroptosis, and expression levels of Caspase-1, GSDMD, IL-1β and TNF-α proteins were significantly lower ( P<0.05) . Conclusion:Inhibition of ROS level in human embryonic trophoblast cells induced by high glucose may promote cell proliferation and reduce the occurrence of pyroptosis by inhibiting TXNIP/NLRP3 signaling pathway.
