Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective:To establish an irritant contact dermatitis(ICD)model induced by sodium dodecyl sulfate(SDS)in mice,and explore its endotype to provide an experimental and theoretical basis for subsequent precise treatment.Methods:Mice were randomly divided into two groups(model group and control group),4%SDS was topically applied to induce ICD in mice,saline was used on control group,the dose and frequency were consistent with model group,and the skin lesions of mice were observed.Epidermal thickness and inflammatory cell infiltration were analyzed by HE staining,toluidine blue staining and immunofluorescence staining.Real-time quantitative PCR was performed to investigate mRNA expression levels of cytokines.Results:Compared with control group,mice in ICD model group showed epidermal thickness on the back of neck,and the numbers of inflammatory cells were increased in dermis.The number of neutrophils,macrophages and T cells were increased.Expressions of Il17a and Il17f mRNA levels were increased.Conclusion:SDS-induced ICD model is successfully established,with the elevated infiltration of neutrophils,macrophages and T cells,and secretion of type 17 cytokines.

Pediatric acute hyperextension spinal cord injury (SCI) named as PAHSCI by us, is a special type of thoracolumbar SCI without radiographic abnormality and highly related to back-bend in dance training, which has been increasingly reported. At present, it has become the leading cause of SCI in children, and brings a heavy social and economic burden. Both domestic and foreign academic institutions and dance education organizations lack a correct understanding of PAHSCI and relevant standards, specifications or guidelines. In order to provide standardized guidance, the expert team formulated this guideline based on the principles of science and practicability, starting from the diagnosis, differential diagnosis, etiology, admission evaluation, treatment, complications and prevention. This guideline puts forward 23 recommendations for 14 related issues.

ObjectiveTo observe the effect of Jianpi Yangzheng Xiaozheng decoction （JYXD） on the proliferation and stemness of the human gastric cancer （GC） cell line HGC-27 by inhibiting aerobic glycolysis， and explore the underlying mechanism. MethodMethyl thiazolyl tetrazolium （MTT） assay was employed to determine the survival rate and chemotherapy sensitivity of HGC-27 cells treated with JYXD （0.25， 0.5， 1， 2， 4， 8， 16， 32 g·L^-1）. Colony formation assay was employed to detect the effect of JYXD （2， 4， 8 g·L^-1） on the colony formation of the cells. The aerobic glycolysis level of HGC-27 cells after treatment with JYXD was measured by glucose assay kit and lactic acid assay kit. The proportion of stem cell subsets in HGC-27 cells was detected by flow cytometry. Western blot was employed to determine the expression of glycolysis-associated proteins such as lactate dehydrogenase （LDH）， hexokinase 2 （HK2）， glucose transporter 1 （GLUT1）， and pyruvate kinase isozyme M2 （PKM2）， and the expression of stemness-associated proteins such as octamer-binding transcription factor 4 （OCT4）， SRY-box transcription factor 2 （SOX2）， and Nanog. ResultJYXD （0.5， 1， 2， 4， 8， 16， 32 g·L^-1） inhibited the activity of HGC-27 cells （P<0.05， P<0.01）， with the inhibitory concentration 50（IC₅₀） of 4.83 g·L^-1， and it improved the sensitivity of HGC-27 cells to cisplatin chemotherapy. Compared with the control group， JYXD （2， 4， 8 g·L^-1） reduced the colony formation number of HGC-27 cells （P<0.01） in a concentration-dependent manner. Flow cytometry showed that compared with that in the control group， the proportion of CD44⁺CD24⁺ALDH⁺ population in the cells treated with JYXD （2， 4， 8 g·L^-1） decreased （P<0.05）. In addition， JYXD （2， 4， 8 g·L^-1） inhibited the glucose uptake and lactic acid production of HGC-27 cells. Western blot showed that compared with the control group， JYXD （2， 4， 8 g·L^-1） down-regulated the expression levels of SOX2， Nanog， OCT4， PKM2， LDH， GLUT1， and HK2 （P<0.05， P<0.01） in a concentration-dependent manner. ConclusionJYXD may inhibit the proliferation and reduce the stemness of HGC-27 cells by regulating the aerobic glycolysis.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Uric acid (UA) is the final product of purine metabolism in human body,and its metabolic disorder will induce hyperuricemia (HUA).The occurrence and development of HUA are associated with a variety of pathological mechanisms such as oxidative stress injury,activation of inflammatory cytokines,and activation of renin-angiotensin-aldosterone system.These mechanisms directly or indirectly affect the bioavailability of endogenous nitric oxide (NO).The decrease in NO bioavailability is common in the diseases with high concentration of UA as an independent risk factor.In this review,we summarize the mechanisms by which high concentrations of UA affect the endogenous NO bioavailability,with a focus on the mechanisms of high-concentration UA in decreasing the synthesis and/or increasing the consumption of NO.This review aims to provide references for alleviating the multisystem symptoms and improving the prognosis of HUA,and lay a theoretical foundation for in-depth study of the correlations between HUA and other metabolic diseases.

Objective: To analyze the spatial and temporal distribution characteristics of seasonal A(H3N2) influenza [influenza A(H3N2)] in China and to provide a reference for scientific prevention and control. Methods: The influenza A(H3N2) surveillance data in 2014-2019 was derived from China Influenza Surveillance Information System. A line chart described the epidemic trend analyzed and plotted. Spatial autocorrelation analysis was conducted using ArcGIS 10.7, and spatiotemporal scanning analysis was conducted using SaTScan 10.1. Results: A total of 2 603 209 influenza-like case sample specimens were detected from March 31, 2014, to March 31, 2019, and the influenza A(H3N2) positive rate was 5.96%(155 259/2 603 209). The positive rate of influenza A(H3N2) was statistically significant in the north and southern provinces in each surveillance year (all P<0.05). The high incidence seasons of influenza A (H3N2) were in winter in northern provinces and summer or winter in southern provinces. Influenza A (H3N2) clustered in 31 provinces in 2014-2015 and 2016-2017. High-high clusters were distributed in eight provinces, including Beijing, Tianjin, Hebei, Shandong, Shanxi, Henan, Shaanxi, and Ningxia Hui Autonomous Region in 2014-2015, and high-high clusters were distributed in five provinces including Shanxi, Shandong, Henan, Anhui, and Shanghai in 2016-2017. Spatiotemporal scanning analysis from 2014 to 2019 showed that Shandong and its surrounding twelve provinces clustered from November 2016 to February 2017 (RR=3.59, LLR=9 875.74, P<0.001). Conclusion: Influenza A (H3N2) has high incidence seasons with northern provinces in winter and southern provinces in summer or winter and obvious spatial and temporal clustering characteristics in China from 2014-2019.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).
