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.

BACKGROUND:D1-3-n-butylphthalide has antioxidant and anti-inflammatory effects and has been explored to have protective role in Parkinson's disease,but the underlying mechanisms are unknown.OBJECTIVE:To investigate the protective effect of D1-3-n-butylphthalide by the approach of network pharmacology,molecular docking,and cellular experimental validation.METHODS:(1)Network pharmacology and molecular docking:The database was used to screen the targets of D1-3-n-butylphthalide and Parkinson's disease.The intersection was taken from the construction of the target protein interaction network,and then screen the core targets.The GO and KEGG pathway enrichment was used to further analyze the core targets.The interaction between the target proteins and D1-3-n-butylphthalide was verified by molecular docking.(2)Cell validation:The passage 6 PC12 cells were divided into six groups for culture.The control group was cultured with conventional culture medium.The model group was cultured with N-methyl-4-phenylpyridinium iodide to induce Parkinson's disease model.The ML385 inhibitor group was added with nuclear factor E2-related factor 2 inhibitor ML385 on the basis of inducing Parkinson's disease model.The D1-3-n-butylphthalide treatment group was added with butylphthalide on the basis of inducing Parkinson's disease model.The D1-3-n-butylphthalide combined with ML385 treatment group was added with D1-3-n-butylphthalide and ML385 on the basis of inducing Parkinson's disease model.The D1-3-n-butylphthalide group was cultured with conventional culture medium containing butylphthalide alone.Cell proliferation,intracellular reduced glutathione and malondialdehyde levels,and protein expression of protein kinase B/glycogen synthase kinase 3β/nuclear factor E2-related factor 2(AKT/GSK-3β/Nrf2)signaling pathway were detected.RESULTS AND CONCLUSION:(1)A total of 52 targets were screened for the intersection of drugs and disease targets,and the core targets including the matrix metalloproteinase 9 and GSK-3β were involved the phosphatidylinositol 3-kinase(PI3K)/AKT and oxidative stress-related signaling pathways.The molecular docking binding energy of D1-3-n-butylphthalide and GSK-3β was-18.27 kJ/mol,which indicated that D1-3-n-butylphthalide had a good binding ability with GSK-3β.(2)Compared with the model group,the PC12 cell activity and reduced glutathione level in the D1-3-n-butylphthalide treatment group were increased(P＜0.05),the malondialdehyde level was decreased(P＜0.05),and the expression of p-AKT,p-GSK-3β,Nu-Nrf2,and T-Nrf2 proteins was increased(P＜0.05).Compared with the D1-3-n-butylphthalide group,the PC12 cell activity and reduced glutathione level in the D1-3-n-butylphthalide combined with ML385 treatment group were decreased(P＜0.05),the malondialdehyde level was increased(P＜0.05),and the expression of Nu-Nrf2 and T-Nrf2 proteins was decreased(P＜0.05).(3)These results demonstrate that D1-3-n-butylphthalide can inhibit oxidative stress and improve cell activity through the AKT/GSK-3β/Nrf2 signaling pathway,and has a protective effect on the Parkinson's cell model induced by N-methyl-4-phenylpyridinium iodide.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: To investigate the relationship between physical activity and genetic risk and their combined effects on the risk of developing chronic obstructive pulmonary disease. METHODS: This prospective cohort study included 318,085 biobank participants from the UK. Physical activity was assessed using the short form of the International Physical Activity Questionnaire. The participants were stratified into low-, intermediate-, and high-genetic-risk groups based on their polygenic risk scores. Multivariate Cox regression models and multiplicative interaction analyses were used. RESULTS: During a median follow-up period of 13 years, 9,209 participants were diagnosed with chronic obstructive pulmonary disease. For low genetic risk, compared to low physical activity, the hazard ratios ( HRs) for moderate and high physical activity were 0.853 (95% confidence interval [ CI]: 0.748-0.972) and 0.831 (95% CI: 0.727-0.950), respectively. For intermediate genetic risk, the HRs were 0.829 (95% CI: 0.758-0.905) and 0.835 (95% CI: 0.764-0.914), respectively. For participants with high genetic risk, the HRs were 0.809 (95% CI: 0.746-0.877) and 0.818 (95% CI: 0.754-0.888), respectively. A significant interaction was observed between genetic risk and physical activity. CONCLUSION Moderate or high levels of physical activity were associated with a lower risk of developing chronic obstructive pulmonary disease across all genetic risk groups, highlighting the need to tailor activity interventions for genetically susceptible individuals.

Objective:To explore the early- to mid-term therapeutic efficacy of using porous-coated metaphyseal sleeves to reconstruct severe bone defects in revision total knee arthroplasty (rTKA).Methods:A retrospective analysis was conducted of the clinical data of the 39 patients (40 knees) who had undergone rTKA by porous-coated metaphyseal sleeve reconstruction at Department of Orthopaedics, West China Hospital, Sichuan University between May 2017 and September 2023. The cohort included 6 males (6 knees) and 33 females (34 knees), with an age of (67.0±9.7) years. The revision was to cure periprosthetic infection after TKA in 12 knees, to correct prosthesis loosening in 19 knees, to treat periprosthetic fracture in 4 knees, to stabilize postoperative joint instability in 4 knees, and to manage postoperative joint stiffness in 1 knee. All patients underwent standard revision procedures, including removal of the original prosthesis, management of bone defects, implantation of revision prosthesis, and adjustment of ligamentous balance and fixation. The patients' surgical time, intraoperative blood loss, incidence of complications, as well as visual analogue scale (VAS), knee range of motion, and Hospital for Special Surgery (HSS) knee joint scores at the last follow-up were recorded.Results:The surgical time was (2.7±0.8) hours, and intraoperative blood loss (337.5±165.4) mL for this cohort. All the 39 patients were followed up for (4.8±2.1) years after surgery. At the last follow-up, their VAS pain score was 2.0 (1.0, 2.0) points, their knee range of motion reached 116.3°±12.2°, and their total score, pain score, and function score of the HSS system were respectively 87.0 (82.8, 89.3) points, 25.0 (22.8, 29.0) points, and 61.0 (60.0, 62.0) points, all showing statistically significant improvements compared with their preoperative values [(6.8±1.7) points, 70.4°±15.2°, (43.1±9.6) points, (9.3±3.1) points, and (33.8±10.1) points] ( P<0.05). In all patients, incisions healed at one stage after surgery, and no complications such as deep vein thrombosis or neurovascular injury occurred. Complications included popliteal artery thrombosis in 1 patient (1 knee) immediately after surgery, acute infection in 1 patient (1 knee) at 3 years after surgery, and periprosthetic fracture due to a traffic accident in 1 patient (1 knee) at 4 years after surgery, and distal prosthesis-related pain in 3 patients (3 knees). Conclusion:Use of porous-coated metaphyseal sleeves in rTKA to reconstruct severe bone defects exhibits favorable early- to mid-term therapeutic outcomes.

Objective:To analyze the clinical efficacy of internal fixation and prosthesis revision in the treatment of periprosthesis fracture after total knee arthroplasty.Methods:A total of 35 patients (35 knees) with periprosthetic fractures after total knee arthroplasty were retrospectively analyzed from January 2008 to January 2022 in the Department of Orthopaedics, West China Hospital, Sichuan University, including 13 males and 22 females, aged 71.4±4.1 years (range, 62-81 years). Left knee 19 cases, right knee 16 cases. There were 20 cases of Rorabeck type II and 15 cases of Rorabeck type III. The initial replacement was performed using a fixed platform post-stabilized knee prosthesis, which was fixed with bone cement. Patients with Rorabeck type II were treated with internal fixation alone (internal fixation group) and patients with Rorabeck type III underwent revision with replacement prosthesis (revision group). The Hospital for Special Surgery (HSS) score, range of motion (ROM) of knee joint, alignment of lower extremity and incidence of postoperative complications were compared between the two groups.Results:All patients successfully completed the operation and were followed up for 5.2±3.6 years (range, 1-12 years). Intraoperative blood loss was 680±102 ml (range, 420-1100 ml). The operative time in the internal fixation group was 105±17 min, which was less than 140±21 min in the revision group, and the difference was statistically significant ( t=-5.450, P<0.001). There was no complication of nerve or blood vessel injury during the operation. Five cases in the internal fixation group had unsatisfactory lower extremity force lines (>3° deviation from normal) after surgery, and all lower extremity force lines in the revision group were satisfied, and the difference in the satisfaction rate of lower extremity force lines between the two groups was not statistically significant ( P=0.057). The fracture healing time, knee ROM and HSS scores at the last follow-up were 5.1±1.3 months, 86°±5° and 84±5 in the internal fixation group and 4.8±1.5 months, 83°±6° and 82±4 in the revision group. One case in the revision group was diagnosed postoperatively with periprosthetic infection with pathogen culture suggestive of Candida albicans, recurrent anterior knee sinus tracts and patellar ectasia, which progressed to osteomyelitis, and mid-thigh amputation was performed 1 year after revision. Conclusion:The stability of prosthesis is an important reference for the treatment of periprosthetic fractures after total knee arthroplasty. Strong internal fixation in patients with unloosened prosthesis and revision with replacement of prosthesis in patients with loose prosthesis can achieve good knee joint function.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective:To explore the clinical correlation and prognostic value of the Albumin-Bilirubin(ALBI)score in children with secondary hemophagocytic syndrome(sHLH).Methods:A retrospective analysis was conducted on the data of children's sHLH cases clearly diagnosed in the Affiliated Hospital of Zunyi Medical University from January 2012 to March 2023.Survival analysis was conducted according to the ALBI classification.Spearman correlation analysis was conducted between the ALBI score and clinical indicators.The Receiver Operating Characteristic(ROC)curve was used to evaluate the ALBI score,select the best cutoff value,and evaluate the accuracy of prognostic prediction value.Kaplan-Meier method was used to draw the survival curve.Log-rank method was used to compare the differences of survival curve between groups.Cox regression was used for prognostic analysis and restricted cubic spline curves used to calculate the relationship between ALBI scores and the risk of death in children with sHLH.Results:A total of 128 children with sHLH were included in this study,with a median age of 38(13.25,84)months.There were 70 males(54.69％)and 58 females(45.31％).The survival analysis results of ALBI grading showed that the survival rate of HLH patients with ALBI grade 3 was significantly lower than those with ALBI grades 1 and 2.Spearman correlation analysis results showed that ALBI score was positively correlated with splenomegaly,respiratory failure,disseminated intravascular coagulation(DIC),pulmonary hemorrhage,gastrointestinal hemorrhage,central nervous system involvement,ALT,AST,TG,LDH,PT,APTT,and SF(the correlation coefficients are:r=0.181,0.362,0.332,0.221,0.351,0.347,0.391,0.563,0.180,0.448,0.483,0.37,0.356),and was negatively correlated with HB,PLT,and FIB(the correlation coefficients are:r=-0.321,-0.316,-0.423),but was not significantly correlated with EBV infection,fungal infection,hepatomegaly,and ANC(P＞0.05).Using the ROC curve,the cutoff value of ALBI was-1.76.Single factor Cox regression analysis results showed that HB＜90 g/L,ALT ≥ 80 U/L,AST≥200 U/L,LDH ≥1 000 U/L,PT ≥20 s,APTT≥40 s,FIB＜1.5 g/L,ALBI ≥-1.76,combined pulmonary hemorrhage,DIC,central nervous system involvement,gastrointestinal bleeding,and not using blood purification may be the prognostic risk factors for children with sHLH(P＜0.05).Multivariate Cox regression results showed that FIB＜1.5 g/L(HR=2.119,95％CI:1.028-4.368),ALBI≥-1.76(HR=2.452,95％CI:1.233-4.875),and central nervous system involvement(HR=4.674,95％CI:2.486-8.789)were independent risk factors affecting prognosis,while blood purification(HR=0.306,95％CI:0.153-0.612)was an independent protective factor for prognosis.The application of restricted cubic splines shows that the risk of death increases with the increase of ALBI score.The area under the ROC curve(AUC)of the ALBI score for predicting the risk of 1-week,2-week,4-week,and overall mortality were 0.825,0.807,0.700,and 0.693,respectively,indicating good predictive performance for early mortality risk.According to subgroup analysis results of clinical manifestations,compared with the ALBI＜-1.76 group,ALBI≥-1.76 was associated with age ≤2 years,EBV infection,HLH-1994/2004 treatment,concomitant respiratory failure,and ANC≤1.0 × 109/L,HB＜90 g/L,PLT＜100 × 109/L,TG≥3.0 mmol/L,LDH ≥ 1 000 U/L,APTT≥40 s,and FIB＜1.5 g/L(P＜0.05).Conclusion:The ALBI score is related to the clinical characteristics and laboratory indicators of sHLH,and can be used as a beneficial indicator for assessing the prognostic risk of sHLH in children.It has good accuracy and clinical application value in predicting the prognosis of sHLH in children.
