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.

Obsessive-compulsive disorder (OCD) is a chronic, disabling mental disorder characterized by distressing and intrusive thoughts (obsessions) and/or repetitive or ritualized behaviors (compulsions), which has a multi-factorial pathogenesis. Recent studies suggest that immune dysregulation is present in OCD patients. Since the immune system plays a crucial role in maintaining central nervous system homeostasis, its dysfunction may be a key factor in the pathogenesis of OCD. This article reviews the current research on the immunological pathogenesis of OCD and explores future research directions, aiming to provide insights into the etiology, subtyping and treatment.

Objective:To investigate the characteristics of anxiety and depression of postgraduates in military medical university under public health emergencies.Methods:By means of self-rating anxiety scale (SAS) and self-rating depression scale (SDS), 944 postgraduate students of a military medical university were investigated to analyze their characteristics of anxiety and depression. SPSS 25.0 was used to statistically analyze the collected data.Results:①The positive rates of anxiety and depression were respectively 8.03% and 8.25%. ②The positive rate of anxiety of male postgraduates was significantly higher than that of female postgraduates ( P=0.035). ③The positive rate of anxiety of serviceman students was significantly higher than that of civilian students ( P=0.022). ④There was no statistical difference in the positive rates of anxiety and depression among postgraduates in different areas ( P > 0.05). ⑤The levels of anxiety and depression of left-behind children were significantly higher than those of unleft-behind children ( P=0.000, P=0.018). ⑥The levels of anxiety and depression of postgraduate students were lower than those of undergraduate students ( P=0.000, P=0.002). Conclusion:Under the outbreak of public health emergencies, anxiety and depression occur in the postgraduates. To strengthen the mental health maintenance of postgraduates in military medical university during the outbreak, it is necessary to pay more attention on the mental health of military students, males and who were left-behind children before.

OBJECTIVE To ev aluate the economical efficiency of nivolumab versus everolimus in the second-line treatment of metastatic clear cell renal cell carcinoma. METHODS From the perspective of China ’s health system ，cost-effectiveness analysis of the two therapies was carried out by developing a three-state partitioned survival model. The clinical parameters were from the updated CheckMate 025 study，and the cost and health utility were from relevant websites and published literatures. The model adopted a 2-week cycle and a lifetime research time. The robustness of the results was verified by sensitivity analysis. The economical efficiency of two therapy schemes were evaluated in the scenario of model simulation time of 80 months and charitable drug donation scheme. RESULTS The results of basic analysis showed that compared with everolimus ，the incremental cost-effectiveness ratio （ICER）of nivolumab was 586 982.60 yuan/quality-adjusted life year （QALY），which was far higher than 3 times of China ’s per capita gross domestic product （GDP）in 2020. The results of single-factor sensitivity analysis showed that the 3 parameters that had the greatest impact on the economic evaluation results were the cost of nivolumab ，the utility value of nivolumab group and everolimus group in progressive disease state. The results of probability sensitivity analysis verified the robustness of the basic analysis results. Results of scenario analysis showed that in the first scenario analysis ，in which model simulation time lasted for 80 months，ICER of nivolumab was 417 204.52 yuan/QALY；in the second scenario analysis ，in which nivolumab charitable drug donation program for low-income people was considered ，ICER of nivolumab was 124 988.58 yuan/QALY. CONCLUSIONS Under the threshold of 1-3 times of China ’s per capita GDP in 2020，compared with everolimus ，it is not economical to use nivolumab as the second-line treatment for metastatic clear cell renal cell carcinoma ； nivolumab is economical when considering its charitable drug donation program for low-income people.

Objective:This meta-analysis was conducted to systematically evaluate the short-term efficacy and safety of indocyanine green fluorescence imaging guided laparoscopic liver tumor resection (FIGLTR).Methods:A systematic search was made for the literature on indocyanine green fluorescence image-guided laparoscopic hepatectomy in randomized, semi-randomized controlled trials and observational studies, and manually search published materials and conference papers in Chinese and English and trace references included in the literature. The retrieval period was up to September 2021. The quality of included studies was evaluated, then the meta-analysis was conducted using Review Manager 5.1 software.Results:Ten studies were included with 803 patients, including 341 in the FIGLTR group and 462 in the non-FIGLTR group. Meta results showed that: Compared to the traditional resection group, indocyanine green fluorescence imaging can significantly shorten the operative time ( MD=-22.61, 95% CI: -34.20--11.03, P<0.001), reduce intraoperative bleeding ( MD=-49.17, 95% CI: -84.99--13.36, P<0.01), shorter hospital stay ( MD=-0.89, 95% CI: -7.72--0.06, P<0.05), Improve the removal rate of R 0 edge ( OR=8.80, 95% CI: 1.96-39.44, P<0.05) and reduce the incidence of postoperative complications ( OR=0.55, 95% CI: 0.34-0.87, P<0.05) of laparoscopic liver tumor resection. There were no differences found in portal block time and transfusion rate. Conclusion:Indocyanine green fluorescence imaging technology provides a new way for safe and accurate laparoscopic resection of liver tumors.

A 24-year-old female patient presented with recurrent itchy annular erythema and scales on the trunk and extremities for 9 years. Histopathological study revealed hyperkeratosis with focal parakeratosis, neutrophil aggregation in the stratum corneum, blisters below the stratum corneum, and perivascular infiltration with lymphocytes, a small number of eosinophils and neutrophils in the superficial and middle dermis. Direct immunofluorescence assay showed negative staining for IgG, IgM, IgA and C3. Whole-exome sequencing of the SPINK5 gene showed a missense mutation c.2423C>T (p.T808I) in exon 25, and a splicing site mutation c.2965-1G>A in exon 31. The compound heterozygosity for the two mutations may be the cause of Netherton syndrome in the patient. Based on the clinical manifestations and genetic testing results, the patient was diagnosed with Netherton syndrome.

Objective To understand the status of Ascaris eggs pollution in soil at national monitoring spots of soil-transmit-ted nematodiasis,so as to provide the evidence for making countermeasures and evaluating the control effect. Methods Ten households were selected from each of the 22 national monitoring spots annually according to the National Surveillance Program of Soil-Transmitted Nematodiasis(Trial),and the soil samples from vegetable gardens,toilet periphery,courtyards and kitchens were collected and examined by using the modified floatation test with saturated sodium nitrate. Fertilized or unfertilized eggs as well as live or dead fertilized eggs were discriminated and identified. In addition,a SWOT analysis of monitoring of Ascaris eggs pollution in the soil of rural China was carried out. Results A total of 1 090 households were monitored in 22 monitoring spots from 2006 to 2010. The total detection rate of Ascaris eggs in the soil was 30.73%,and the detection rates of fertilized,unfertilized and live fertilized eggs were 13.21%,26.42%and 20.28%,respectively. The total detection rates of Ascaris eggs in the vegetable garden,toilet periphery,courtyard and kitchen were 16.51%,13.49%,14.22% and 10.73% respectively. The SWOT analysis demonstrated that the monitoring work had both advantages and disadvantages,and was faced with opportunities as well as threats. Conclusion The pollution status of Ascaris eggs in the soil is still quite severe at some national monitoring spots,and the counter-measures such as implementing hazard-free treatment of stool,improving water supply and sanitation and reforming environment should be taken to protect people from being infected.
