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 explore the effectiveness of the diffusion of innovation theory in com-bination with multidisciplinary nursing collaboration in intervention for patients with severe pneumonia complicated by heart failure.Methods A total of 120 patients with severe pneumonia complicated by heart failure admitted between April 2021 and April 2024 were enrolled and randomly divided into observation group(n=60)and control group(n=60)using a random black-and-white ball method.The control group received conventional nursing intervention,while the observation group received an intervention model combining the diffusion of innovations theory with multidisciplinary collaboration on top of the conventional nursing.Rehabilitation outcomes(time to control of pulmonary inflammation,time to resolution of cough and expectoration,length of hospital stay)and post-intervention cardiac function[left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV)]were compared between the two groups.The Minnesota Living with Heart Failure Questionnaire(MLHFQ)was used to assess quality of life,and the Self-Care Heart Failure Index(SCHFI)was used to evaluate self-care behaviors.Complications were compared between the two groups,and cost-effectiveness was analyzed(patient medical expenses and re-hospitalization rates).Results The observation group had shorter time to resolution of cough and expectoration,control of pulmonary inflammation,and length of hospital stay compared with the control group,with statistically significant differences(P＜0.05).After intervention,LVEF increased in both groups compared with pre-intervention lev-els,and was higher in the observation group than in the control group,with a statistically significant difference(P＜0.05);ESV decreased in both groups compared with pre-intervention levels,and was lower in the observation group than in the control group,with a statistically significant difference(P＜0.05).After intervention,physiological,emotional,and social functioning scores in the MLHFQ decreased in both groups compared with pre-intervention levels,and were lower in the ob-servation group than in the control group,with statistically significant differences(P＜0.05).After intervention,scores for self-care maintenance,self-care management,and self-care confidence in the SCHFI increased in both groups,and were higher in the observation group than in the control group,with statistically significant differences(P＜0.05).There was no statistically significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion The combination of the diffusion of innovations theory and multidisciplinary collaboration nursing model can accelerate the rehabilitation process in patients with severe pneumonia complicated by heart fail-ure,improve their quality of life,and effectively enhance their self-care abilities.

Objective:To investigate the feasibility of oblique overlap anastomosis plus single flap valvuloplasty (OSF) for reconstruction after laparoscopic proximal gastrectomy.Methods:The C-shaped seromuscular flap (2.5 × 3.5 cm), which was 2 cm from the top of the remnant stomach, was extracorporeally created on the anterior wall of the remnant stomach. The stomach was opened approximately 1.0 cm above the lower edge of the mucosal flap. Four supporting stitches were sutured around the hole and the right wall of the esophageal stump was incised with a support suture to prevent the linear stapler from entering the submucosa. Liner stapler was inclined to the left side of the esophagus at an angle of about 30 degrees to the longitudinal axis of the esophagus for oblique anastomosis between the dorsal side of the esophagus and the anterior stomach and then esophagogastrostomy was performed with the length of anastomosis was 4 cm. Entry hole was suture with 3 stitches and then the linear stapler was used for closing the entry hole. Finally, the seromuscular flap was closed using barbed sutures.Results:Clinical data of 11 patients with Siewert type II esophagogastric junction adenocarcinoma who underwent radical gastrectomy and reconstruction by OSF between January 2022 and May 2023 were retrospectively collected. There were 7 males and 4 females. The average age was (69.9±7.8) years, the BMI was (21.7±7.2) kg/m 2 and the tumor size was (2.1±0.6) cm. OSF reconstruction was successfully completed in all 11 patients. The median operative time was 275 (270-428) minutes, the time for OSF reconstruction was 112 (80-140) minutes, and the blood loss was 50 (20-400) ml. The pathological stage was 0-I in 7 cases and II-III in 4 cases. The patients were fed on the 4th day (4-7 days) and discharged from hospital on the 7th day (6-9 days) after surgery. No patient had gastroesophageal reflux symptoms of grade B and above, and no patient took anti-reflux medicine. Conclusions:OSF is a safe and feasible treatment for Siewert type II esophagogastric junction adenocarcinoma.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

This study was designed to investigate the effet of phillyrin(PHI)on sciatic nerve injury in diabetic peripheral neuropathy(DPN)rats based on the high mobility group protein box-1(HMGB1)/advanced glycation end product receptor(RAGE)signal pathway.DPN rat model was established by high fat and high sugar diet combined with injection of streptozotocin(STZ)solution,and the rats were randomly grouped into model group,phillyrin low dose(PHI-L,50 mg/kg)group,phillyrin medium dose(PHI-M,100 mg/kg)group,phillyrin high dose(PHI-H,200 mg/kg)group,and positive drug(mecobalamin,250 μg/kg)group,while another rats with normal diet were treated as the control group.Each group consisted of 10 rats.The conduction velocity of sciatic nerve was measured by BL-420S biological function experiment system;fasting blood glucose(FBG)level was detected by blood glucose meter;the levels of serum HbAlc,IL-6 and TNF-α were measured with ELISA kits;the ultrastructure of sciatic nerve was observed with electron microscope;the levels of ROS,SOD,MDA and MBP in sciatic nerve were detected with commercial kits;the mRNA and protein levels of HMGB1 and RAGE in sciatic nerve were detected by RT-qPCR and Westem blotting.Compared with model group,pathological injury of rats in PHI-M group,PHI-H group and positive drug group was significantly alleviated,the sciatic nerve conduction velocity and MBP/SOD levels were significantly recovered,the levels of FBG,HbAlc,IL-6,TNF-α,and the mRNA and protein levels of ROS,MDA,HMGB1 and RAGE were decreased significantly(P＜0.05).In conclusion,PHI can reduce the inflammatory reaction,reduce DPN in rats,thus plays a therapeutic role,and the mechanism may be related to the inhibition of HMGB1/RAGE signal pathway.

Objective:To construct a prediction model for neurogenic shock in patients with traumatic cervical spinal cord injury and validate its effectiveness.Methods:A retrospective case-control study was conducted on the clinical data of 381 patients with traumatic cervical spinal cord injury admitted to the Third Hospital of Shanxi Medical University from January 2017 to December 2022, including 311 males and 70 females, aged 12-86 years [(55.1±12.9)years]. A total of 121 patients (31.8%) were complicated with neurogenic shock. The patients were randomly divided into training set ( n=267) and validation set ( n=114) with a ratio of 7∶3. The training set was divided into neurogenic shock group ( n=81) and non-neurogenic shock group ( n=186) according to whether they were complicated with neurogenic shock. The general data, clinical data, laboratory indicators and imaging data of the patients were collected. Univariate analysis was used to determine differences in the aforementioned indicators between the neurogenic shock group and non-neurogenic shock group in the training set. Multivariate Logistic regression analysis was conducted to screen the predictors for neurogenic shock in patients with traumatic cervical spinal cord injury, and regression equation was constructed. A nomogram prediction model based on the regression equation was plotted with R programming language. Receiver operating characteristic (ROC) curves of the training set and validation set were plotted, when the area under the curve (AUC) was calculated to determine the discriminability of the model. The calibration of the model was assessed with calibration curves. The clinical applicability of the model was evaluated by the decision curve analysis (DCA). Results:The univariate analysis showed that there were statistically significant differences in the American Spinal Injury Association (ASIA) grade, tracheal intubation, serum albumin concentration within 24 hours on admission, intramedullary lesion length (IMLL), maximum spinal cord compression (MSCC), increased signal intensity (ISI), and highest damaged segment between the neurogenic shock group and non-neurogenic shock group in the training set ( P<0.05). The multivariate Logistic regression analysis revealed that AISA grade (grade C vs. grade A: OR=0.13, 95% CI 0.03, 0.59, P<0.01; grade D vs.grade A: OR=0.04, 95% CI 0.01, 0.28, P<0.01), serum albumin concentration within 24 hours on admission ( OR=0.75, 95% CI 0.65, 0.86, P<0.01), IMLL ( OR=2.71, 95% CI 1.68, 4.38, P<0.01), ISI (grade 2 vs.grade 0: OR=5.62, 95% CI 1.07, 29.48, P<0.05), and highest damaged segment ( OR=0.49, 95% CI 0.29, 0.83, P<0.01) were predictors for neurogenic shock in patients with traumatic cervical spinal cord injury. Based on the 5 forementioned variables, the regression equation was constructed as follows: Logit[ P/(1- P)]=10.99-1.06×＂AISA grade＂-0.29×＂serum albumin concentration within 24 hours on admission＂+1.04×＂IMLL＂+0.89×＂ISI＂-0.74×＂highest damaged segment＂. In the prediction model constructed based on the equation, the AUC values of the training set and validation set were 0.97 (95% CI 0.97, 0.99) and 0.95 (95% CI 0.91, 0.99). Calibration curves of the training set and validation set demonstrated the prediction curve roughly overlapped with the reference curve and the mean absolute errors of the two sets were 0.013 and 0.050. DCA results showed that the net benefit rate of patients was greater than 0 when the threshold probability ranged from 0% to 97% for the training set and from 0% to 100% for the validation set. Conclusion:The prediction model based on the AISA grade, serum albumin concentration within 24 hours on admission, IMLL, ISI, and highest damaged segment demonstrates good discriminability, calibration and clinical applicability in predicting neurogenic shock in patients with traumatic cervical spinal cord injury.

Biological age (BA) is a marker to accurately assess aging, facilitating the prediction of age-related diseases and promoting healthy aging. In recent years, first- and second-generation organ-system-specific BA has been developed using chronological age (CA) or aging-related outcomes (mortality) as training phenotypes and data from questionnaires, physical examinations, clinical biochemistry, imaging, and multi-omics to investigate the specificity of organ systems aging. Here, we review the methodologies for constructing BA, current efforts to assess organ system-specific BA, and related genome-wide association studies (GWAS). Previous studies predominantly used the first-generation BA method, using CA as training phenotypes. Organ-system-specific BA can accurately predict the disease risk of corresponding organ systems. We propose the development of organ system-specific BA through second-generation BA models and conducting GWAS and Mendelian randomization studies to explore organ system-specific aging processes, which will provide a theoretical foundation for the clinical application of organ system-specific BA.
