Objective To establish a competency evaluation indicator system for school physicians. Methods A preliminary pool of competency indicators for school physicians was established through systematic literature review and policy document analysis. The Delphi method was used to conduct two rounds of expert consultations with 16 experts who involve in educational administration, clinical medicine, public health management, and school healthcare. Based on the opinions of the experts, the indicator system was screened, revised, and refined to establish the final competency evaluation indicator system for school physicians. Results The questionnaire recovery rates of the two rounds of expert consultations were both 100.0%. The expert authority coefficient were 0.93 and 0.94, and Kendall′s coefficients of concordance were 0.21 and 0.26, respectively (both P<0.01). The final competency evaluation indicator system for school physicians consisted of five primary indicators, including basic medical service capacity, school health service capacity, health education and communication capacity, professional ethics and competency, and self-improvement capacity, as well as 35 secondary indicators (items). All indicators received relatively high importance scores. The system demonstrated a reasonable structure, good scientific validity, and practical applicability. Conclusion The competency evaluation indicator system for school physicians developed in this study demonstrates high scientific validity and practicality. It can serve as an important tool for school physician management, competency development, and performance evaluation, providing references for improving school health service quality and strengthening the construction of school physician teams.

Objective To evaluate the efficiency of health resource allocation in 22 types of hospital institutions in Guangdong Province from 2018 to 2022,identify their strengths and shortcomings in resource utilization,and offer evidence-based recommendations for optimizing medical resource allocation and policymaking.Methods The efficiency of health resource allocation was assessed using the DEA-BCC model and the DEA-Malmquist index model across the 22 hospital categories.Results In 2022,the overall resource allocation efficiency of the 22 types of hospital institutions in Guangdong Province was suboptimal,with an average score of 0.657.From 2018 to 2022,the mean total factor productivity(TFP)change index for these hospitals was 0.968,with only 6 categories exhibiting a TFP index exceeding 1.Conclusion The efficiency of health resource allocation in Guangdong's hospitals remains inadequate.Government authorities should enhance macro-level planning for regional resource distribution,accelerate advancements in medical technology,and establish a real-time monitoring framework.Concurrently,policy interventions and incentive mechanisms should be reinforced to ensure both scientifically sound allocation and effective utilization of medical resources.

Objective:To analyze the regional differences in health resource allocation in Guangdong Province and provide references for optimizing health resource allocation in Guangdong Province. Methods:The health resource density index,entropy weight-TOPSIS method,and RSR method were used to comprehensively evaluate the allocation of health resources in Guangdong Province from 2018 to 2022. Results:The results of the entropy weight-TOPSIS analysis showed that the average levels of comprehensive evaluation in the Pearl River Delta,Western Wing (West Guangdong),Eastern Wing (East Guangdong),and mountainous areas (North Guangdong) from 2018 to 2022 were 0.4452,0.1338,0.2144 and 0.0566,respectively. The RSR grading results show that Zhuhai,Dongguan,Guangzhou and Shenzhen had better allocation of health resources,with a"good"grading result;Shaoguan,Yunfu and Heyuan are worse. Conclusion:There is an obvious regional difference in the allocation of health resources in Guangdong Province. The allocation level of health resources in the Pearl River Delta and the Eastern Wing (East Guangdong) is relatively high,while the allocation level of health resources in the western wing (West Guangdong) and the mountainous areas (North Guangdong) is relatively low. In the future,Guangdong Province should pay attention to the areas with poor allocation of health resources,develop regional characteristic economy,strengthen the training of health talents,optimize the allocation of health resources,and realize that all people in the province can enjoy high-quality,convenient and equal medical and health services. At the same time,it is also necessary to strengthen cooperation and exchanges among regions to jointly promote the comprehensive development of health undertakings in Guangdong Province.

5-(4-Hydroxyphenyl)-3H-1,2-dithiole-3-thione (ADT-OH) is a slowly releasing H2S donor with some neuroprotective effect.In order to study the structure-activity relationships,seventeen compounds (Y1-Y17) were synthesized by modification of ADT-OH at the aromatic ring position,and their structures were confirmed by 1H NMR,13C NMR and HR-MS.Among them,6 compounds (Y4,Y13-Y17) were novel compounds.Their effects had been evaluated on HT-22 hippocampal neuron cells damaged by glutamate with MTF method.The pharmacological results demonstrated that all the Y compounds had potent neuroprotection at most of the tested concentrations (1-100 μmol/L).Compounds Y1-Y9 and Y11 significantly improved the survival rates of the damaged cells at 1-100 μmol/L (P ＜0.01).Specially,compounds Y1,Y4,Y6-Y9,Yu are more potent than their parent compound ADT-OH at concentration of 1-10 μmol/L,which is worthy of further study.

Objective To investigate the effects of aerobic exercise during chemotherapy on cancer-related fatigue in breast cancer patients, and related mechanism thereof. Methods Sixty breast cancer patients who underwent radical surgery were randomly assigned to exercise group and control group, 30 patients for each group. Patients in exercise group received regular nursing care plus aerobic exercise during chemotherapy, while patients in control group only received regular nursing care. The revised Piper fatigue scale (RPFS) was used to assess the fatigue degree. Values of hemoglobin concentration(Hb), maximal oxygen uptake (VO2max) and RPFS scores were detected before chemotherapy, at the end of chemotherapy and 4 weeks after chemotherapy, respectively. Results There was no significant difference in Hb concentration before chemotherapy, at the end of chemotherapy and 4 weeks after chemotherapy between two groups (P>0.05). The level of Hb was significantly lower at the end of chemotherapy and 4 weeks after chemotherapy than that before chemotherapy in two groups (P<0.05). There were no significant differences in VO2max and RPFS score before chemotherapy between two groups (P>0.05). At the end of chemotherapy and 4 weeks after chemotherapy, there were no significant differences in VO2max and RPFS scores than those before chemotherapy in exercise group (P>0.05). In control group, value of VO2max was significantly lower at the end of chemotherapy and 4 weeks after chemotherapy than that before chemotherapy (P<0.05), RPFS score was significantly higher than that before chemotherapy (P<0.05). Conclusion Aerobic exercise during chemotherapy can be effectively against cancer-related fatigue, which may be related to the inhibitory effect of aerobic exercise on debasement of VO 2max.
