RESUMEN
Objective To identify the current research hotspots of global health training, and construct a global health talent training evaluation index system. Methods Publications pertaining to global health talent training evaluation were retrieved in China National Knowledge Infrastructure, Wanfang Database, and Web of Science Core Collection from 2003 to 2022, and keywords were extracted from eligible publications for co-occurrence and cluster analyses using the CiteSpace software. Based on keywords clustering results, a global health talent training evaluation index system was constructed using a context, input, process, and product (CIPP) evaluation model as a theoretical framework. Results A total of 692 Chinese publications and 1 264 English publications were included. Keyword co-occurrence and cluster analyses yielded 10 Chinese and 10 English keyword clusters, and the 10 Chinese keyword clusters included analytic hierarchy process, health diplomacy, personnel structure, crossdiscipline, educational assessment, global health discipline development, training needs, curriculum program, quality evaluation and logistics support, while the English keyword clusters included evidence-based practice, capacity building, global health, quality of life, machine learning, leadership, sub-Saharan Africa, health equity, global health security and global health diplomacy. Based on keyword clustering, a global health talent training evaluation index system was constructed with CIPP as the theoretical framework, which contained 4 primary indicators, 15 secondary indicators and 59 tertiary indicators, and the primary indicators included 4 dimensions of context evaluation, input evaluation, process evaluation and product evaluation. Conclusions A global health talent training evaluation index system has been constructed, which provides an effective evaluation tool and quantitative evidence for future global health talent training.
RESUMEN
Depressive disorder seriously affects people's physical and mental health.Acupuncture is a safe and effective treatment for depression,yet,its mechanism is unclear.Therefore,acupuncture's action mechanism in intervening depression was summarized from several perspectives,including morphology and ultrastructure of neurons in depression-related brain areas,function and structure of glial cells,brain functional and structural connectivity,and neuroelectrophysiology.It's discovered that acupuncture can repair the morphological and ultrastructural damage of neurons in the hippocampus and prefrontal lobe,mitigate the functional and structural injuries of glial cells in the hippocampus and prefrontal lobe,strengthen functional connectivity and heal structural connection,and promote neuroelectrophysiological activities,which possibly are the principal mechanisms of how acupuncture works in intervening depressive disorder.
RESUMEN
Objective To investigate the characteristics of symptom burden and extract symptom clusters in lung cancer patients at the end of thoracic radiotherapy.Methods Lung cancer patients receiving Thoracic Radiotherapy were collected from 20 tertiary hospitals in China,including Guang'anmen Hospital of the Chinese Academy of Traditional Chinese Medicine,during November 2014—September 2017,and the MDASI-TCM scale assessed patient symptoms at the end of radiotherapy,and descriptive statistics and exploratory factor analysis explored symptom burden and the distribution of TCM symptom clusters.Results At the end of radiotherapy,45.1%of patients reported two or more moderate to severe symptoms,with fatigue being the most prevalent and severe symptom.Fatigue(31.4%),cough(30.9%),expectoration(24.1%),distress(23.2%)and shortness of breath(20.9%)were the top five symptoms from the highest to the lowest in the incidence of moderate to severe symptoms.The enjoyment of life(36.4%)had the highest incidence of interference with moderate to severe symptoms.Exploratory Factor analysis extracted three symptom clusters,namely the excessive heat and damaged yin-Spleen and stomach disorders related symptom cluster,the heart and spleen-deficient related symptom cluster,and the lung qi-unfriendly related symptom cluster,with a cumulative variance contribution of 70.1%.Conclusion Lung cancer patients undergoing thoracic radiotherapy have a certain symptom burden at the end of radiotherapy.The identification of symptom burden and symptom group characteristics is conducive to promoting standardization of TCM syndrome differentiation and laying a preliminary foundation for formulating reasonable and effective TCM intervention measures in the future.
RESUMEN
Rejection has constantly been an unresolved challenge in the field of organ transplantation. The research on the mechanism of rejection plays a significant role in improving the efficacy of organ transplantation and enhancing the survival rate of graft. The innate and specific immune responses of the human body jointly participate in the graft rejection, leading to graft injury. In recent years, multiple researchers have conducted in-depth studies on the mechanism underlying the role of microRNA (miR) in regulating rejection. Among them, miR-155 has been widely considered as a key factor involved in immune regulation. The expression level and functional status of miR-155 may be intimately associated with the occurrence of rejection, which may become a new target for overcoming rejection. In this article, relevant studies on the role of miR-155 in regulating key immune cells in innate and specific immune responses were reviewed, aiming to provide novel ideas for the development of new immunosuppressants and rejection therapy.
RESUMEN
Objective:To investigate the epidemiological and clinical features of patients with hemorrhagic fever with renal syndrome (HFRS) from 2017 to 2019.Methods:Seventy-five patients with HFRS from the Department of Infectious Diseases, The First Affiliated Hospital of Anhui Medical University during January 1, 2017 to December 31, 2019 were included. The data of epidemiology, clinical symptoms, blood routine, urine routine, serum creatinine, liver function and other laboratory examination indexes were retrospectively analyzed. The measurement data with skewness distribution were expressed by M( QR) and compared by nonparametric test. Multivariate logistic regression analysis was used to analyze disease-related risk factors. Results:The 75 patients were mainly located in the western and northern regions of Anhui Province. A total of 37 cases (49.3%) were infected during November, December and January next year. Fifty-four (72.0%) patients were farmers and 10(13.3%) patients had a clear history of rodent contact. Only 19(25.3%) patients had typical clinical manifestations of "three red and three pain" . Fifty-eight (77.3%) patients had elevated white blood cell count, 67(89.3%) patients had decreased platelet count, 55(73.3%) patients had urinary protein + + + , 65(86.7%) patients had abnormal urinary occult blood, and 67(89.3%) patients had elevated serum creatinine. The serum creatinine and potassium levels in 31 severe and critical patients were 495(301) μmol/L and 4.14(0.77) mmol/L, respectively, which were both higher than those in 44 mild and moderate patients (235(289) μmol/L and 3.65(1.02) mmol/L, respectively). The differences were both statistically significant ( Z=-3.187 and -2.796, respectively, both P<0.01). Multivariate logistic regression analysis showed that serum creatinine (odds ratio ( OR)=1.005, 95% confidence interval ( CI)1.002-1.008) and serum potassium ( OR=2.632, 95% CI 1.098-6.313) were independent risk factors for disease severity. All patients received comprehensive medical treatment, and 27 patients received renal replacement therapy. Sixty-eight patients had good prognosis and four patients died. Conclusions:HFRS is still common in the rural area in winter and spring. Patients with atypical clinical manifestations and severe and critical patients should be intensively monitored.

Objective To analyze the differences of clinical manifestations and organ damage between patients with severe fever with thrombocytopenia syndrome(SFTS)and patients with tsutsugamushi disease,and to investigate the prognostic factors of SFTS.Methods The research was performed on 49 patients with SFTS and 16 patients with tsutsugamushi disease who visited the First Affiliated Hospital of Anhui Medical University from October 2014 to June 2017.The general information of patients including region,age,gender and clinical manifestations were evaluated.Blood routine,liver and kidney function,myocardial enzyme levels,lipase,amylase,electrolytes,C-reactive protein,procalcitonin,prothrombin time(PT)and activated partial thromboplastin time(APTT)were continuously monitored during the course of disease.T test was used for continuous variables of normal distribution,and non-parametric test was used for variables of non-normal distribution.Chi-square test was used for categorical variables.Results The mean age of SFTS patients was 62.1±15.5(ranging from 17 to 87 years)and the mean age of tsutsugamushi patients was 56.1±9.2(ranging from 47 to 73 years).There was no significant difference between the two groups(t=1.47,P=0.147).There were 25 males(51%)in SFTS patients and 8 males(50%)in tsutsugamushi disease patients.There was no significant difference between the two groups(x2=0.005,P=0.943).The incidences of headache,vomiting,superficial lymphadenectasis,disturbance of consciousness,proteinuria,hematuria,pulmonary infection,multiple organ dysfunction and acute pancreatitis in SFTS patients were all significantly higher than those in tsutsugamushi disease patients(x2=8.82,4.38,8.71,11.17,7.88,5.56,4.35,9.43,and 8.13,respectively,P <0.05 or 0.01).The counts of leukocytes(Z=2.73),neutrophils(Z=2.46),lymphocytes(Z=3.15),platelets(Z=4.25),albumin(Z=2.65)and sodium ion(t=2.10)in SFTS patients were all significantly lower than those in patients with tsutsugamushi disease(P <0.05 or 0.01).The levels of aspartate aminotransferase(Z=2.94),lactate dehydrogenase(Z=3.42),creatine kinase(CK)(Z=2.88),amylase(Z=2.11),lipase(Z=2.82),creatinine(Z=2.07)and urea nitrogen(Z=2.50)in fatal SFTS patients were all significantly higher than those in patients with tsutsugamushi disease(P <0.05 or 0.01).Among 49 SFTS patients,16 patients died and 33 patients recovered finally.The age(t=3.33),platelet count(Z=2.55),alanine aminotransferase(ALT)(Z=2.10),aspartate aminotransferase(AST)(Z=2.22),lactate dehydrogenase(Z=2.26),CK(Z=3.50),CK-MB(Z=3.10),creatinine(Z=2.17),urea nitrogen(Z=2.36),and sodium(t=2.65)between the two subgroups had significant differences(P <0.05 or 0.01).Conclusions SFTS is more severe and has high mortality,while tsutsugamushi disease has a better prognosis.Early differential diagnosis and early rational treatment are important to reduce the mortality of patients with SFTS.
RESUMEN
Vascular endothelial cell glycocalyx is a layer of glycoprotein complex located on the surface of endothelial cells, forming a selective permeation barrier on the surface of endothelial cells. In the present review, after a brief introduction of glycocalyx, the relationship between glycocalyx and mass transport under fluid sheer stress (FSS), especially the relationship between glycocalyx and macromolecules such as low density lipoprotein (LDL) has been discussed. This relationship was reflected as following: on the one hand, the thickness and integrity of the glycocalyx affects the concentration polarization of LDL and its transendothelial transport and heparan sulfate proteoglycan (HSPG) participates in the whole process of residual lipoproteins metabolism. On the other hand, ox-LDL, an oxidized product of LDL, destroys heparan sulfate (HS) which is a major component of the endothelial cell glycocalyx. The study on relationship between vascular endothelial glycocalyx and lipoproteins will provide a new clue to elucidate the pathogenesis of atherosclerosis and provide more evidence to view the glycocalyx as a new control target.
