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.

Periodontitis is a common oral disease caused by bacteria coupled with an excessive host immune response. Stem cell therapy can be a promising treatment strategy for periodontitis, but the relevant mechanism is complicated. This study aimed to explore the therapeutic potential of mitochondria from human embryonic stem cell-derived mesenchymal stem cells (hESC-MSCs) for the treatment of periodontitis. The gingival tissues of periodontitis patients are characterized by abnormal mitochondrial structure. Human gingival fibroblasts (HGFs) were exposed to 5 μg/mL lipopolysaccharide (LPS) for 24 h to establish a cell injury model. When treated with hESC-MSCs or mitochondria derived from hESC-MSCs, HGFs showed reduced expression of inflammatory genes, increased adenosine triphosphate (ATP) level, decreased reactive oxygen species (ROS) production, and enhanced mitochondrial function compared to the control. The average efficiency of isolated mitochondrial transfer by hESC-MSCs was determined to be 8.93%. Besides, a therapy of local mitochondrial injection in mice with LPS-induced periodontitis showed a reduction in inflammatory gene expression, as well as an increase in both the mitochondrial number and the aspect ratio in gingival tissues. In conclusion, our results indicate that mitochondria derived from hESC-MSCs can reduce the inflammatory response and improve mitochondrial function in HGFs, suggesting that the transfer of mitochondria between hESC-MSCs and HGFs serves as a potential mechanism underlying the therapeutic effect of stem cells.

Malignant tumors are one of the main causes of death from chronic diseases in China,and their incidence and mortality rates show an in-creasing trend year by year.Advanced non-surgical treatment of malignant tumors is an important means of improving patients'prognosis and en-hancing their quality of life.The traditional Chinese medicine Ganoderma lucidum has anti-tumor ef-fects and plays a role in the treatment of many ma-lignant tumors.In this paper,a systematic review of the effects of Ganoderma lucidum active ingredi-ents on tumors has been conducted at home and abroad in the past five years to explore the anti-tu-mor mechanism of Ganoderma lucidum active in-gredients and to lay a theoretical foundation for the application of Ganoderma lucidum active ingre-dients in clinical practice.

Objective To analyze the impact of mini plate and cannulated screw internal fixation on joint function recovery in patients with posterior malleolus fracture.Methods A total of 150 patients with posterior malleolus fractures,treated at our hospital from March 2021 to June 2023,were included in this study.They were divided into two groups using the odd-even number method.The control group consisted of 75 patients who underwent cannulated screw internal fixation,while the study group comprised 75 patients who received mini plate internal fixation.Clinical indicators,ankle range of motion,ankle function,and health status were compared and analyzed between the two groups.Additionally,levels of inflammatory factors,postoperative complications,and clinical efficacy were assessed.Results In terms of operation time and intraoperative blood loss,there was no statistically significant difference between the two groups(P＞0.05).However,the study group exhibited shorter ambulation days,fracture healing time,and hospitalization days compared to the control group(P＜0.05).Moreover,the study group demonstrated significantly improved ankle dorsiflexion,ankle plantar flexion,foot varus and foot valgus range of motion compared to the control group(P＜0.05).Additionally,higher AOFAS score and KPS score were observed in the study group as compared to the control group(P＜0.05).Furthermore,levels of IL-6,IL-8 and CRP were lower in the study group than in the control group(P＜0.05).The incidence of postoperative complica-tions was also lower in the study group than in the control group(P＜0.05).Conclusion Mini plate internal fixa-tion for posterior malleolus fracture yields ideal outcomes by promoting improvement in clinical indicators and ankle range of motion while effectively enhancing ankle function,reducing inflammatory reaction as well as minimizing postoperative complications.

Objective To investigate the predictive value of white blood cell count,LDL-C and fasting blood glucose on the occur-rence of AMI in elderly patients with coronary atherosclerotic heart disease(CAD).Methods A total of 210 elderly patients with CAD were selected and divided into the AMI group as the case group and the chronic CAD group as the control group based on clinical manifes-tations and laboratory and coronary angiography results.The general data,laboratory data,coronary angiography results,and other clinical information of the two groups were retrospectively analyzed.We used the Logistic regression analysis to explore the risk factors for acute myocardial infarction in elderly CAD patients and the receiver operating characteristic curve(ROC)to evaluate the predictive efficacy of white blood cell count,LDL-C and fasting blood glucose on the occurrence of AMI in elderly CAD patients.Results Compared with the chronic CAD group,the AMI group had a higher smoking rate,white blood cell count,CRP,ALT,AST,D-D dimer,fasting blood glu-cose,total cholesterol,LDL-C and Gensini score and lower LVEF(P＜0.05).The Logistic regression analysis showed that white blood cell count(β=0.859,P＜0.001,OR=2.361),LDL-C(β=1.003,P=0.009,OR=2.728)and fasting blood glucose(β=0.495,P=0.007,OR=1.641)were independent risk factors for AMI in elderly CAD patients.The ROC curve analysis showed that when the cut-off values of fasting blood glucose,white blood cell count,and LDL-C were 4.895mmol/L,7.19 x 109/L and 2.635 mmol/L respectively,the area under the curve for predicting AMI was the largest,with values of 0.734,0.859 and 0.735.The area un-der the ROC curve of the combination of the three is 0.902.Conclusion White blood cell count,LDL-C and fasting blood glucose are associated with AMI in elderly patients with CAD.Higher levels of white blood cell count,LDL-C and fasting blood glucose indicate a higher risk of AMI.The combination of the three can serve as a more valuable predictive index.

BACKGROUND: One of the most important treatment modalities for non-small cell lung cancer (NSCLC) is immune checkpoint inhibitor. Nevertheless, a small percentage of patients do not respond well to these therapies, highlighting the significance of identifying important CD8+ T cell subsets for immunotherapy and creating trustworthy biomarkers. The purpose of this study is to assess the potential utility of TIM3+CD8+ T cells as new biomarkers by examining their expressions in various areas of the NSCLC tumor microenvironment. METHODS: Based on biopsy techniques, tumor tissue samples were obtained from patients with NSCLC and categorized into tumor central and non-central regions. Using flow cytometry, the infiltration of TIM3+CD8+ T cells and the surface expression of programmed cell death 1 (PD-1) on these cells were examined, and their correlations with the effectiveness of immunotherapy were assessed. RESULTS: The non-central region of tumor tissues had considerably larger infiltration of TIM3+CD8+ T lymphocytes compared to the non-central region (P<0.0001). This pattern was found in both subgroups with tumor diameters ≥3 cm or <3 cm (P<0.01). In comparison to TIM3-CD8+ T cells, TIM3+CD8+ T cells showed higher levels of PD-1 (P<0.001), with more PD-1+TIM3+CD8+ T cells invading the non-central region (P<0.01). Clinical responders to immunotherapy had considerably lower infiltration levels of TIM3+CD8+ T cells in the tumor non-central region compared to non-responders, with lower levels correlated with better clinical outcomes (P<0.01), while no correlation was identified in the tumor central region (P>0.05). According to reciever operating characteristic (ROC) curve analysis, TIM3+CD8+ T cells in the tumor non-central region had an area under the curve (AUC) of 0.9375 for predicting the effectiveness of immunotherapy, which was considerably higher than that of TIM3+CD8+ T cells in the tumor central region and programmed cell death ligand 1 (PD-L1) [tumor proportion score (TPS)]. CONCLUSIONS In the tumor microenvironment of NSCLC, TIM3+CD8+ T cells show regional distribution patterns. The expression of this cell population in the non-central region of the tumor microenvironment may be a biomarker for predicting the effectiveness of immunotherapy.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Objective: To compare the safety between cervical conization (CC) alone and hysterectomy for patients with adenocarcinoma in situ (AIS) of the cervix. Methods: Patients diagnosed with AIS after CC during 2007–2021 were identified by computerized databases at Women’s Hospital of Zhejiang University School of Medicine. A total of 453 AIS patients were divided into 2 groups according to uterus preservation: hysterectomy group (n=300) and CC(s) alone group (n=153). The prevalence of residual disease and disease recurrence was compared between patients treated by CC(s) alone and hysterectomy. The prevalence of residual disease in specimens from women who had a hysterectomy and repeat CC were compared between positive and negative margins of CC. The factors influencing residual disease and disease recurrence were assessed. Results: Among 310 specimens from women who had a hysterectomy or repeat CC, the prevalence of residual disease was 50.6% (45/89) for a positive margin and 2.3% (5/221) for a negative margin (p=0.000). Four patients had recurrence of vaginal intraepithelial neoplasia in those treated by hysterectomy and one had recurrence of cervical squamous intraepithelial neoplasia in those treated by CC(s) alone. The prevalence of recurrence was 0.7% (1/153) for CC(s) alone and 1.3% (4/300) for hysterectomy (p=0.431). Hysterectomy did not influence residual disease or disease recurrence. Conclusion CC is an efficacious and safe option for patients with AIS of the cervix provided the margin is negative.

OBJECTIVE: To examine the bone proportional measurement standard on the chest and abdomen of modern women. METHODS: The height, weight and distances of bone proportional measurement chest and abdomen of 101 young females were measured. The height was divided by 75 to calculate the data of bone proportional measurement, and compared with the national standard published in 2006 and the ancient literature of Miraculous Pivot: Gudu. RESULTS: The bone proportional distances between two nipples and two coracoid processes of women were 8 cun and 12 cun respectively, which were in line with the 2006 national standard. The bone proportional distance from navel to superior margin of pubic symphysis (Qugu) was 6.5 cun, which was consistent with the ancient literature of Miraculous Pivot: Gudu. The bone proportional distance from suprasternal fossa to the middle point of xiphisternal synchondrosis (Qigu) was less than 9 cun, while the bone proportional distance from Qigu to navel was more than 8 cun, resulting in the ratio less than 9︰8. The bone proportional distance from suprasternal fossa to the middle point of xiphoid process was 9 cun, corresponding to the ratio of 9︰8 when comparing with the measurement from the middle point of xiphoid process to navel. CONCLUSION The bone proportional distance measurement between two nipples and two coracoid processes of women should follow the 2006 national standard, and the bone proportional distance measurement from navel to superior margin of pubic symphysis should follow the standard of Miraculous Pivot: Gudu. The middle point of xiphisternal synchondrosis should be replaced by the middle point of xiphoid process.
