Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

OBJECTIVES: To investigate the molecular mechanism by which salvianolic acid B (Sal-B) modulates mitochondrial functional homeostasis and alleviates myocardial ischemia-reperfusion (I/R) injury in mice. METHODS: Mouse cardiomyocyte HL-1 cells were pretreated with 5 μmol/L Sal-B with or without sh-Sirt1 transfection before exposure to hypoxia-reoxygenation (HR), and the changes in ATP production, mitochondrial superoxide activity, substrate oxidation level were evaluated. In the animal experiment, 36 C57BL/6J mice were randomized into 3 groups (n=12) for sham operation or ligation of the left anterior coronary artery to induce myocardial I/R injury with or without intravenous injection of Sal-B+I/R (50 mg/kg). In the rescue experiment, 60 adult C57BL/6J mice were randomized into 5 groups (n=12): sham-operated group, myocardial I/R group, Sal-B+I/R group, I/R+Sal-B+Sirt1fl/fl group, and I/R+Sal-B+cKO-Sirt1 group. Myocardial injury was evaluated with HE staining, and cardiac function was assessed by measurement of the ejection fraction and fractional shortening using echocardiography. RESULTS: In HL-1 cells with HR injury, Sal-B pretreatment significantly increased cellular ATP production, reduced mitochondrial superoxide anion levels, and enhanced oxygen consumption level. In the mouse models of myocardial I/R injury, Sal-B pretreatment markedly ameliorated I/R-induced structural disarray of the cardiac myocytes and improved cardiac ejection. Cycloheximide chase with Western blotting and ubiquitination assays after Sirt1-IP showed that Sal-B significantly inhibited Sirt1 degradation in HL-1 cells. Sirt1 knock-down reversed Sal-B-induced increases in ATP production, reduction in superoxide, and elevation of OCR in HL-1 cells. Cardiomyocyte-specific Sirt1 knockout obviously reversed Sal-B-mediated improvement in cardiac ejection function and myocardial structure damage in mice with myocardial I/R injury. CONCLUSIONS Sal-B promotes mitochondrial functional homeostasis in cardiomyocytes with HR injury and improves cardiac function in mice after myocardial I/R by inhibiting Sirt1 protein degradation.

Objective To analyze the clinical manifestations of delayed serological transfusion reactions(DSTR)after platelet transfusion in tumor patients,and to explore the transfusion strategy.Methods Clinical data and laboratory test re-sults of patients with positive antibody screening were analyzed after platelet transfusion in our hospital from January 1,2015 to June 30,2023,and the incidence rate,clinical characteristics and transfusion strategy of patients with DSTR were ana-lyzed.Results A total of 2 553 patients with 6 057 platelet transfusions were reviewed.Eight patients developed DSTR and received a total of 21 therapeutic amounts of platelets,and 5 patients were subsequently transfused with red blood cells.Rh system antibodies were detected in 7 cases(4 anti-E,1 anti-c/E,1 anti-C and 1 anti-c)and Kell system antibodies in 1 case.Conclusion Tumor patients may also develop DSTR after platelet transfusion.It is necessary to pay close attention to the antibody situation and perform matched transfusion when transfusing blood again.

Objective:To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021.Methods:A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children.Results:The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M ( Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 ( χ 2trend=111.427, P<0.001). The median of urinary iodine concentration M ( Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [ M ( Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [ M ( Q1, Q3): 173.00 (113.00, 250.30) μg/L] ( P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95% CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95% CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95% CI: 2.64%-3.10%), 588/20 530] ( P=0.001). Conclusion:From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

Influenza imposes a significant disease burden on society and individuals annually, and influenza vaccination is considered a significant public health measure to prevent influenza and reduce influenza-related severe disease and death. The low influenza vaccination rate in China is partly due to certain factors affecting the willingness and behavior of individuals to receive them. Scientific research and targeted interventions on these factors can effectively improve the vaccination situation. Commonly used individual-level theoretical models for influenza vaccination behavior include the health belief model, protection motivation theory, and theory of planned behavior. This study reviews theoretical models commonly employed in researching influenza vaccination willingness and behavior. An overview of these practical applications and challenges models is presented to provide references for relevant research and intervention programs in China.

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 This study aims to explore the associations between threat and deprivation childhood traumas and dysfunctional attitudes among patients with major depressive episode,based on the dimensional model of adversity and psychopathology(DMAP).Methods Data from 970 patients with major depressive episode were collected and categorized based on the childhood trauma questionnaire-short form(CTQ-SF)scores into no trauma(426),threat-only(86),deprivation-only(210),and mixed groups(248).Cognitive distortions were assessed using the dysfunctional attitudes scale(DAS),with scores above the upper quartile indicating significant distortions.Multifactorial logistic regression analysis was employed to examine the association between threat and deprivation and dysfunctional attitudes.Results There were significant differences in the proportion of cognitive distortions among the no trauma,threat-only,deprivation-only,and mixed groups(19.25% vs.30.23% vs.20.00% vs.35.89%,P<0.001),with differences across all dimensions(P≤0.001).Multifactorial logistic regression revealed a positive correlation between threat and overall cognitive distortions(OR=2.031,P<0.001),and specific positive correlations with dimensions such as vulnerability(OR=1.709,P<0.001),appeal and repulsion(OR=2.088,P<0.001),perfectionism(OR=2.321,P<0.001),compulsivity(OR=1.765,P=0.001),approval seeking(OR=1.837,P<0.001),dependency(OR=1.554,P=0.006),and autonomous attitudes(OR=1.864,P<0.001).In contrast,deprivation was only positively correlated with the cognitive philosophy dimension(OR=1.495,P=0.015).Conclusion Childhood trauma is closely associated with dysfunctional attitudes in patients with major depressive episode.Threat correlates positively with cognitive distortions in all dimensions except cognitive philosophy,whereas deprivation correlates only with the cognitive philosophy dimension.

Objective:To investigate the clinicopathological characteristics of rashes in monkeypox patients through a series of skin biopsies, and examine their pathological features and the most effective tests.Methods:Patients with monkeypox virus infection admitted to Beijing Ditan Hospital from June to August 2023 were identified. Among them, 24 patients underwent skin biopsies for clinical pathological study that were included in this study. Clinical information, rash pictures, and nucleic acid test results were analyzed using histopathology, immunohistochemistry, RNAscope ? hybridization and electron microscopy. Results:All 24 patients were male, including 14 patients with concurrent human immunodeficiency virus infection. Their average age was (32.3±5.4) years. The nucleic acid test confirmed monkeypox virus infection. The clinical feature of monkeypox rashes was solitary rather than clustered distribution, with rashes occurring in similar phase, distinguishing it from herpesvirus. The rashes in these patients were mostly scattered, with an average of (13.0±11.8) rashes, and most commonly present in the perineum, face, limbs, and trunk. The three main pathological features of these rashes were ballooning degeneration of the epidermal spinous cell layer, the characteristic intra-cytoplasmic Guarnieri′s bodies and significant infiltration of inflammatory cells in whole dermal layer. Immunohistochemistry, RNAscope ? hybridization, and electron microscopy can all effectively detect the monkeypox virus. Electron microscopy showed viral replication in various types of skin cells. Conclusions:The study describes the pathological features of monkeypox virus rashes. Pathological examination of skin biopsy samples is helpful to diagnose these rashes. The study suggests that the monkeypox virus has a unique epitheliotropic affinity and can infect various types of cells in the skin.
