Construction of competitive endogenous RNA network mediated by lung ischemia-reperfusion core genes / 器官移植

Objective To analyze the core genes of lung ischemia-reperfusion injury and construct a competitive endogenous RNA (ceRNA) network. Methods Original data of GSE145989 were downloaded from the Gene Expression Omnibus (GEO) database as the training set, and the GSE172222 and GSE9634 datasets were used as the validation sets, and the differentially-expressed genes (DEG) were identified. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Protein-protein interaction (PPI) network was constructed, and the core genes were screened, and the diagnostic values of these core genes and the immune infiltration levels of immune cells were evaluated. The ceRNA network was constructed and validated. The targeted drugs based on ceRNA network were assessed. Results A total of 179 DEG were identified, including 61 down-regulated and 118 up-regulated genes. GO analysis showed that DEGs were associated with multiple biological processes, such as cell migration, differentiation and regulation, etc. They were correlated with cell components, such as vesicle membrane, serosa and membrane raft, etc. They were also associated with multiple molecular functions, such as chemokine receptor, G protein-coupled receptor, immune receptor activity and antigen binding, etc. KEGG pathway enrichment analysis revealed that DEG were involved in tumor necrosis factor (TNF), Wnt, interleukin (IL)-17 and nuclear factor (NF)-κB signaling pathways, etc. PPI network suggested that CD8A, IL2RG, STAT1, CD3G and SYK were the core genes of lung ischemia-reperfusion injury. The ceRNA network prompted that miR-146a-3p, miR-28-5p and miR-593-3p were related to the expression level of CD3G. The miR-149-3p, miR-342-5p, miR-873-5p and miR-491-5p were correlated with the expression level of IL-2RG. The miR-194-3p, miR-512-3p, miR-377-3p and miR-590-3p were associated with the expression level of SYK. The miR-590-3p and miR-875-3p were related to the expression level of CD8A. The miR-143-5p, miR-1231, miR-590-3p and miR-875-3p were associated with the expression level of STAT1. There were 13 targeted drugs for CD3G, 4 targeted drugs for IL-2RG, 28 targeted drugs for SYK and 3 targeted drugs for lncRNA MUC2. No targeted drugs were identified for CD8A, STAT1 and other ceRNA network genes. Conclusions CD8A, IL2RG, STAT1, CD3G and SYK are the core genes of lung ischemia-reperfusion injury. The research and analysis of these core genes probably contribute to the diagnosis of lung ischemia-reperfusion injury and providing novel research ideas and therapeutic targets.

Aim To analyze the differences in plasma biomarkers and metabolic pathways between Atractylodes chinensis and Atractylodes coreana after intervention in spleen deficiency rats, and discuss the spleen strengthening mechanism of the two from a non targeted metabolomics perspective. Methods A spleen deficiency model was established in SD rats using a composite factor method of improper diet, excessive fatigue, and bitter cold diarrhea. To determine the content of gastrointestinal and immunological indicators, UHPLC-QE-MS technology was used, combined with principal component analysis (PC A) and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) methods to search for biomarkers in plasma of spleen deficiency rats, and metabolic pathways were induced using the Pathway database. Results After administration of Atractylodes chinensis and Atractylodes coreana, various indicators in plasma of spleen deficiency rats showed varying degrees of regression. Metabolomics analysis showed that Atractylodes chinensis and Atractylodes coreana respectively recalled 70 and 82 plasma differential metabolites. Atractylodes chinensis mainly regulated two metabolic pathways : "Glycine, serine, and threonine metabolism, and "Thiamine metabolism". Atractylodes coreana mainly regulated five metabolic pathways, "Glycine, serine, and threonine metabolism", "Thiamine metabolism, "Pyrimidine metabolism", "Butanoate metabolism", and "Riboflavin metabolism". Conclusions Both Atractylodes chinensis and Atractylodes coreana have certain regulatory effects on spleen deficiency rats, and their mechanism of action may be related to regulating metabolic pathways such as "Glycine, serine, and threonine metabolism, and "Thiamine metabolism"in spleen deficiency.

Relationship between core function and pressure pain threshold in senior women with non-specific chronic low back pain: cross-sectional study / Relação entre a função do core e o limiar de dor a pressão em mulheres idosas com dor lombar crônica inespecífica: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic nonspecific low back pain (CNLBP) is a public health issue. Dysfunctions in muscle activation and spinal stability are estimated to directly impact pain intensity. Additionally, senior women experience greater decline in muscle function due to aging, rendering this demographic more susceptible to developing low back pain. The aim of this study was to analyze the correlation between core muscle instability, strength, and endurance with pressure pain threshold in senior individuals with CNLBP. METHODS: This is a quantitative observational study, with a descriptive cross-sectional design, conducted on women aged 60 to 79 years. The pressure pain threshold (PPT). The pressure pain threshold (PPT) was assessed using a pressure algometer applied to the paravertebral and anterior tibial musculature. Trunk instability was assessed on both a stable and an unstable seat, positioned atop a force platform that provided real-time displacement of the pressure center. Maximum isometric strength and endurance of trunk flexors and extensors were assessed using the McGill protocol. Person's correlations coefficient (r) was calculated, and the data were presented as mean and standard deviation. The significance level was set at p<0.05. RESULTS: This study included 49 senior women (67,3±5,6 years; body mass index of 28,5±5,2 kg/m2; pain intensity of 4,6±2,3 on a 0-10scale). No correlation was observed between PPT at L3, L5 and TA with lumbar instability, maximum isometric strength and trunk muscle endurance. CONCLUSION: In this study, no correlation was found between lumbar instability, maximum isometric strength and trunk muscle endurance with the PPT in senior women with CNLBP.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor lombar crônica inespecífica (DLCI) é um problema de saúde pública. Estima-se que disfunções na ativação muscular e na estabilidade da coluna possam repercutir diretamente na intensidade da dor. Além disso, em decorrência da idade, as mulheres idosas apresentam maior declínio na função muscular, tornando esse público mais suscetível a desenvolver a dor lombar. O objetivo deste estudo foi analisar a correlação entre instabilidade, força e resistência dos músculos do core com o limiar de dor por pressão em idosas com DLCI. MÉTODOS: Trata-se de um estudo observacional quantitativo, com delineamento transversal descritivo, realizado em mulheres com idade entre 60 e 79 anos. O limiar de dor por pressão (LDP) foi avaliado com um algômetro de pressão na musculatura paravertebral (bilateralmente ao processo espinhoso nível de L3 a L5) e cinco cm abaixo da tuberosidade da tibial direita no tibial anterior. A instabilidade de tronco foi avaliada em um assento estável e outro instável, posicionados sobre uma plataforma de força para análise do deslocamento do centro de pressão em tempo real. A força isométrica máxima e a resistência de flexores e extensores do tronco foi avaliada por meio do protocolo de McGill. Foi calculado o coeficiente de correlação de Pearson (r), os dados foram expressos em média e desvio padrão e o valor considerado significativo quando p<0,05. RESULTADOS: Participaram deste estudo 49 mulheres (67,3±5,6 anos; índice de massa corporal de 28,5±5,2 kg/m2; intensidade da dor 4,6±2,3 em uma escala de 0- a 10). Não foi encontrada correlação entre o LDP em L3, L5 e TA com instabilidade lombar, força isométrica máxima e resistência dos músculos do tronco. CONCLUSÃO: Não foi encontrada, neste estudo, uma correlação entre a instabilidade lombar, a força isométrica máxima e a resistência dos músculos do tronco com o LDP em mulheres idosas com DLCI.

Biomechanical impact of labiolingual diameter on endodontically treated anterior teeth with crown restoration under occlusal loading

Abstract Objective To evaluate the effect of the labiolingual diameter and construction of an endodontically treated (ET) anterior tooth with crown restoration on stress distribution and biomechanical safety under occlusal loading. Methodology Three-dimensional finite element models were generated for maxillary central incisors with all-ceramic crown restorations. The labiolingual diameters of the tooth, defined as the horizontal distance between the protrusion of the labial and lingual surfaces, were changed as follows: (D1) 6.85 mm, (D2) 6.35 mm, and (D3) 5.85 mm. The model was constructed as follows: (S0) vital pulp tooth; (S1) ET tooth; (S2) ET tooth with a 2 mm ferrule, restored with a fiber post and composite resin core; (S3) ET tooth without a ferrule, restored with a fiber post and composite resin core. A total of 12 models were developed. In total, two force loads (100 N) were applied to the crown's incisal edge and palatal surface at a 45° oblique angle to the longitudinal axis of the teeth. The Von Mises stress distribution and maximum stress of the models were analyzed. Results Regardless of the loading location, stress concentration and maximum stress (34.07~66.78MPa) in all models occurred in the labial cervical 1/3 of each root. Both labiolingual diameter and construction influenced the maximum stress of the residual tooth tissue, with the impact of the labiolingual diameter being greater. A reduction in labiolingual diameter led to increased maximum stress throughout the tooth. The ferrule reduced the maximum stress of the core of S2 models (7.15~10.69 MPa), which is lower compared with that of S3 models (19.45~43.67 MPa). Conclusion The labiolingual diameter exerts a greater impact on the biomechanical characteristics of ET anterior teeth with crown restoration, surpassing the influence of the construction. The ferrule can reduce the maximum stress of the core and maintain the uniformity of stress distribution.

Clinical longevity of metallic versus fiberglass intraradicular posts: a systematic review / Longevidade clínica de pinos intraradiculares metálicos versus de fibra de vidro: uma revisão sistemática

Objective: This systematic review aims to compare the clinical longevity of metallic and fiberglass intraradicular posts in teeth with severely compromised crowns, utilizing randomized clinical trials and case reports published in the last eleven years. Material and Methods: The research was conducted on PubMed, Medline, Lilacs, and BBO databases using the first search strategy with the descriptors 'dental posts,' 'longevity,' 'fiberglass-reinforced posts' or 'metallic posts.' The second search strategy involved analyzing the references of articles identified by the first search. Both studies were carried out with stringent inclusion and exclusion criteria. Results: No statistically significant and clinically relevant differences in longevity were observed between metallic and fiberglass posts. Conclusion: The clinical success and durability of the restorative procedure using intraradicular posts primarily depend on the remaining amount around the post (ferrule), the type and position of the tooth in the arch (impacting the masticatory forces exerted on the restored tooth), and the correct application of the cementation technique. It is noteworthy that fiberglass posts offer substantial advantages by presenting a modulus of elasticity similar to dental structure, ensuring a more homogeneous distribution of masticatory forces and reducing the risk of fractures. These findings have practical implications for material selection in restorative procedures involving intraradicular posts.(AU)

Objetivo: Esta revisão sistemática visa comparar a longevidade clínica de pinos intrarradiculares metálicos e de fibra de vidro em dentes com coroas severamente comprometidas, através de estudos clínicos randomizados e relatos de casos, publicados nos últimos onze anos. Material e Métodos: A pesquisa foi conduzida nas bases de dados PubMed, Medline, Lilacs e BBO, utilizando a primeira estratégia de busca com os s 'pinos dentais' e 'longevidade' e 'pinos reforçados com fibra de vidro' ou 'pinos metálicos'. A segunda estratégia de busca consistiu na análise das referências dos artigos identificados pela primeira estratégia. Ambos os estudos foram delineados com critérios rigorosos de inclusão e exclusão. Resultados: Não se constataram diferenças estatisticamente significativas e clinicamente relevantes na longevidade entre pinos metálicos e de fibra de vidro. Conclusão: O êxito clínico e a durabilidade do procedimento restaurador empregando pinos intrarradiculares dependem primordialmente da quantidade de remanescente ao redor do pino (férula), do tipo e posição do dente na arcada (o que impacta nas forças mastigatórias exercidas sobre o dente restaurado) e da aplicação correta da técnica de cimentação.Destaca-se que o pino de fibra de vidro oferece vantagens substanciais ao apresentar módulo de elasticidade similar à estrutura dentária, assegurando uma distribuição mais homogênea das forças mastigatórias e reduzindo o risco de fraturas (AU)

Evaluation of core decompression outcome in systemic lupus erythematosus with hip osteonecrosis: a retrospective cohort study

Abstract Background Osteonecrosis is a major cause of morbidity for patients with systemic lupus erythematosus (SLE). Although core decompression is an approved and trusted technique to prevent further joint deterioration, this surgical method seems to be less beneficial for SLE patients. We aimed to evaluate the outcomes of core decompression in SLE patients with primary stages of femoral head osteonecrosis. Methods In this study, 23 patients (39 affected hip joints) with osteonecrosis of the femoral head with stage II of the disease, based on the Ficat-Arlet classification system, underwent core decompression. Also, patients demographic characteristics, clinical data, medication history, comorbidities, immunological findings, hip plain radiographs, history of total hip arthroplasty after core decompression, and patients satisfaction with joint function according to the Oxford hip score questionnaire were obtained. Results In the study, 53.8% of affected joints showed signs of radiographic deterioration in follow-up imaging. Sixty-one and a half percent (61.5%) of patients had unsatisfactory joint performance. A third (33.3%) of affected hip joints underwent total hip arthroplasty up to 5 years from core decompression. SLE patients with a history of receiving bisphosphonate were 83.2% less dissatisfied with their joint function than patients without a history of bisphospho-nate use (P < 0.02). Of the 23 studied cases, the mean cumulative dose of prednisolone before and after core decompression surgery was 46.41 mg and 14.74 mg respectively. Besides, one case (2.6%) that had a high anti-phospholipid antibodies level during follow-up did not have any radiographic deterioration, and 9 cases (23.1%) had some degrees of radiographic deterioration. Conclusions The patients group that used bis-phosphonate, had a higher level of satisfaction with joint function after core decompression. Patients with high-level anti-phospholipid antibodies are related to a poor prognosis after core decompression.

Prescription audit in post-operative patients of Dr. B. R. Ambedkar Medical College and Hospital, Bengaluru

Background: Prescribing drugs are an important skill which needs to be continuously assessed and refined accordingly. Many drugs especially antimicrobials and fixed dose combinations that maybe irrational are being prescribed. Hence, this study was undertaken to analyze the rational prescribing guidelines in post-operative patients which will help doctors to update their knowledge and improve their attitude toward selecting cost effective treatment. Aim and Objectives: The aims of this study were as follows: (i) To evaluate prevailing prescription trends and (ii) to evaluate rationality of prescriptions in post-operative cases of surgery, orthopedics, obstetrics, and gynecology (OBG), and Otorhinolaryngology (ORL) departments. Materials and Methods: A prospective observational study was conducted in post-operative wards of departments of surgery, orthopedics, ORL, and OBG of Dr. B. R. Ambedkar Medical College and Hospital, Bengaluru. The study duration was 15 months from December 2018 to March 2020 with a sample size of 2000. Results: In the present study, female preponderance (54.4%) was seen. Majority of the drugs (77.3%) were prescribed under brand name. The most common group of drugs prescribed was non-steroidal anti-inflammatory drugs (135%) and the antibiotic was Cephalosporins (77.5%). As per the World Health Organization (WHO) core prescribing indicators, 6.25 were the average drugs per prescription. Conclusion: According to the WHO core prescribing indicators, polypharmacy was observed and prescribing by generic name was also less. However, there was no irrational use of antibiotics in post-operative cases in our study which reduces the chances of development of antibiotic resistance. Practice of prescribing drugs from the essential drugs list (EDL) was less. The study suggests incorporating educative initiative, development of drug policy, and an EDL-based hospital formulary to ensure rational use of medicines.

Mining Novel Anti-Nocardia Drug Targets Based on Pan-genomics and Subtractive Proteomics / 中山大学学报(医学科学版)

ObjectiveNocardia is an apathogen that causes opportunistic infections in humans and has a global distribution. In recent years， resistance of Nocardia to commonly used drugs have been observed， highlighting the urgent need for the identification of new drug targets and the development of novel antimicrobial agents against Nocardia. MethodsThirty-one complete genome sequences of Nocardia strains were retrieved from the GenBank database. Pan-genomic analysis was performed using BPGA， and drug target candidates were screened using subtractive proteomics. Homology modeling was employed to predict the 3D structures of target proteins， and potential drugs targeting these proteins were predicted using DrugBank. Molecular docking techniques were utilized to validate the binding activity between the drugs and target proteins. ResultsThe pan-genomic analysis of the 31 Nocardia strains revealed 1 421 core proteins. Fifteen candidate drug target proteins were identified through subtractive proteomics analysis. Among them， the physicochemical properties of the OG1493 protein （such as amino acid count， molecular weight， isoelectric point， grand average of hydropathicity， fat index，and instability index Ⅱ） were found to be most suitable for a drug target protein. Using the DrugBank database， seven compounds， namely Adenosine-5'-Rp-Alpha-Thio-Triphosphate， alpha，beta-Methyleneadenosine 5'-triphosphate， Phosphoaminophosphonic Acid-Adenylate Ester ，Radicicol，2-Hydroxyestradiol， p-Coumaric acid， and Ethylmercurithiosalicylic acid were identified as potential compounds capable of exerting anti-Nocardia effects by targeting this protein. Molecular docking results indicated a strong binding affinity between the target protein and these compounds. The experimental result showed that that Radicicol could be a potential antibacterial drug targeting this particular protein. ConclusionPan-genomic analysis and subtractive proteomics are valuable approaches for mining novel anti-Nocardia drug targets.

Effectiveness of platelet-rich plasma as an adjunct to core decompression to treatment outcomes and femoral head preservation in avascular necrosis of the hip: A meta-analysis of randomized controlled trials

Background@#Avascular necrosis (AVN) of the femoral head results from intraosseous pathology causing functional impairment. Early diagnosis allows conservative treatment like core decompression, delaying total hip arthroplasty.@*Objective@#This meta-analysis aims to summarize platelet-rich plasma's (PRP) impact as an adjunct to core decompression (CD) on treatment outcomes and femoral head preservation in hip AVN. @*Methods@#The study conducted a comprehensive literature search using PubMed, Cochrane Library, Science Direct, Google Scholar and Med Line, including randomized controlled trials (RCTs) and previous meta-analyses from various databases. Using a random effects model, it compared PRP+CD with bone grafting to CD with bone grafting alone in AVN patients, evaluating function, pain scores, disease progression and the need for hip surgery.@*Results@#The meta-analysis examined 1041 records and included three studies. The primary outcomes were function and pain scores using Harris Hip Scoring (HHS) and Visual Analog Scale (VAS). Postoperative HHS scores at final follow-up favored the PRP+CD group significantly over CD alone. Postoperative VAS scores showed a trend towards higher scores in the CD alone group. The PRP+CD group demonstrated higher survival from disease progression compared to CD alone. Overall, the study suggests that PRP+CD led to better functional outcomes and disease progression outcomes than CD alone in AVN of the hip.@*Conclusion@#The PRP+CD treatment group showed significant benefits in AVN patients compared to CD alone, including higher HHS scores, improved disease progression survival and reduced need for hip surgery. Although PRP+CD resulted in decreased VAS scores, the difference was not statistically significant.

Screening of Clinical Efficacy Evaluation Indicators for Traditional Chinese Medicine Injections based on Mixed Method Research / 中医杂志

Currently， evidence on the efficacy and risk of traditional Chinese medicine （TCM） injections is seriously insufficient， and it is difficult to evaluate TCM injections comprehensively， truly and objectively using available efficacy evaluation indicators. Therefore， establishing a clinical efficacy evaluation system that can effectively reflect TCM injections is imperative. Core outcome set （COS） has played an important role in screening TCM efficacy evaluation indicators， however， there are still certain problems， such as large differences in efficacy indicators， non-standardization， and lack of featured and specific TCM indicators. Mixed method research （MMR） has the advantages of looking at problems from both quantitative and qualitative perspectives. It is thereby proposed to use COS and MMR integrated model to establish a clinical efficacy evaluation indicator system that not only fully considers the cha-racteristics of TCM injections， but also highlights the efficacy and advantages of TCM injections from the perspective of TCM intervention. Simultaneously， an indicator screening method using MMR to optimize COS research model is formulated， which can provide ideas for the research on efficacy evaluation indicators of TCM injections.

OBJECTIVE@#To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies.@*METHODS@#A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI.@*RESULTS@#All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up.@*CONCLUSION@#For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

Research ideas of core formulas-syndromes based on disease-syndrome-treatment combination / 中国中药杂志

The relationship between disease and syndrome is a research focus in integrated traditional Chinese and western medicine. Depending on the focus, the disease-syndrome combination for treatment is manifested as the different treatment methods for the same disease and the same treatment method for different diseases based on the syndrome, and different treatment methods for the same syndrome and the same treatment method for different syndromes based on the disease. The mainstream model is the combination of di-sease identification in modern medicine with syndrome identification and core pathogenesis in traditional Chinese medicine. However, current research on the combination of disease and syndrome and core pathogenesis tends to focus on the heterogeneity between disease and syndrome and the separation of syndrome and treatment. Therefore, the study proposed the research idea and model of core formulas-syndromes(CFS). According to the theory of formula-syndrome correspondence, the research idea of CFS deepens the research on core pathogenesis, which aims to summarize the core formulas and syndromes for diseases. The research fields include diagnostic criteria for the indications of formulas, distribution patterns of formulas and syndromes for diseases, the evolution of medicinal-syndrome based on formulas-syndromes, formula combination law based on formulas-syndromes, and the dynamic evolution of formulas-syndromes. Through the summary of ancient classics, clinical experience, and medical records, and with the methods of expert consultation, factor analysis, and clustering analysis, research on the diagnostic criteria for the indications of formulas aims to explore the diagnosis information such as the diseases, symptoms, signs, and pathophysiology. The research on the distribution patterns of formulas and syndromes for diseases tends to summarize the specific types of formulas and syndromes for the diseases through literature research and clinical cross-sectional studies based on the establishment of diagnostic criteria for the indications of formulas. The research on the evolution of medicinal-syndrome aims to clarify the medicinal-syndrome law through literature and clinical research. The formula combination law refers to the fact that the core prescriptions for a disease often appear in combination with other prescriptions on a regular basis. The dynamic evolution of formulas-syndromes refers to the continuous transformation and change of formulas and syndromes in the process of disease development with changes in time and space. The CFS is conducive to the unification of disease, syndrome and treatment and to the deepening of the research model of disease and syndrome integration.

Construction of a core competency training indicator system for high-level public health talents / 预防医学

Objective@#To construct a core competency training indicator system for high-level public health talents using the Delphi method, so as to provide insights into optimization of high-level public health talents training.@*Methods@#Based on review of publications pertaining to core competency training for high-level public health talents, in combination with public health priorities and development needs in China, a preliminary indicator system was constructed. Twenty public health experts were invited for two rounds of Delphi expert consultation. Indicators were screened based on the frequency of full marks, mean score and coefficient of variation (CV), and the weight of indicators was determined using the Entropy weight method. The effectiveness of the Delphi expert consultation was evaluated using the active degree, authority coefficient and the consistency degree. @*Results@#Twenty experts participated in the consultation, including 12 men, and there were 6 experts at ages of 30 to 39 years, 8 at ages of 40 to 49 years, and 6 at ages of 50 years and older. There were 17 experts with an educational level of master and above, 19 with senior professional titles and all experts had working experiences for 10 years and longer. The active degrees were 95.24% and 100.00% for two rounds of consultations, and the overall authority coefficient was 0.87. Following two rounds of consultations, all CVs were reduced to below 0.25, and the coordination coefficients were all statistically significant (P<0.05), with a higher coordination coefficient in the second round of consultation than in the first round. The constructed core competency training indicator system for high-level public health talents included four primary indicators, including health protection, health service improvement, health promotion, and essential quality, with weights of 0.388, 0.310, 0.122 and 0.180, 11 secondary indicators, with high weights seen for protection of human health from threats (0.178), monitoring and assessment of health service utilization (0.157) and promotion of health service quality and access (0.112), and 70 tertiary indicators, with high weights seen for Chinese writing (0.038), capability for health policy suggestions (0.034) and global perspective (0.030).@*Conclusion@#The core competency training indicator system for high-level public health talents constructed in this study may provide insights into training of high-level public health talents.
