ABSTRACT
Objective To establish a method and study the pharmacokinetics for concentration determination of effective components in Xiakucao Xiaoliu mixture in Normal Rat Plasma By LC-MS/MS. Methods The mobile phase was methanol-water (0.1% formic acid) system under the positive ion mode of C18 chromatographic column, gradient elution was adopted, and the flow rate was 0.3 ml/min. In the negative ion mode, the mobile phase was acetonitrile-water (0.1% formic acid) system, gradient elution, with a flow rate of 0.4 ml/min. Caffeic acid, rosmarinic acid, syringic acid, rutin in positive ion mode and Atractylodes lactone II and Atractylodes lactone III in negative ion mode were respectively determined. Normal rats were intragastrically given Xiakucao Xiaoliu Mixture 7.8 ml/kg, and blood was taken from the orbit at different time points after the administration. The blood concentration was determined by the validated LC-MS/MS method and the non-standard DAS2.0 software was used. The pharmacokinetic parameters of rats after administration were calculated by the compartment model. Results The pharmacokinetic parameters belonged to non atrioventricular model. The pharmacokinetic characteristics of the four main anti-cancer active ingredients of Caffeic acid, Rosmarinic acid, Syringic acid and Atractylodes Ⅲ in rats after administration of Xiakucao Xiaoliu Mixture were significantly different from those reported in the literature after the administration of monomers. Conclusion The established method was simple, accurate and sensitive, which could be suitable for the content determination of effective components in Xiakucao Xiaoliu mixture in Normal Rat Plasma, which would be a valuable information for the study on main anticancer active substances.
ABSTRACT
ObjectiveTo explore the obstacles and causes of communication and cooperation among doctors, nurses and rehabilitation therapists in a stroke rehabilitation team. MethodsFrom July to October, 2022, twelve rehabilitation evaluation meetings were observed using ethnographic research, based on Shared Mental Model theory. Semi-structured interviews were held with five doctors, ten nurses and four rehabilitation therapists. ResultsFour themes and nine sub-themes were presented, namely equipment (poor interoperability of information system, limited knowledge of rehabilitation equipment for doctors and nurses), task (members were under time pressure to attend meeting, imperfect inter-discipline communication system), team interaction (insufficient information sharing, unfamiliar with roles/responsibilities, misunderstanding between specialties) and team member (less participation of nurses, limited multidisciplinary knowledge). ConclusionThe communication and cooperation among stroke rehabilitation team members is limited by many factors, such as equipment, task, team interaction and team members. It is suggested to improve interoperability of information systems, create a supportive environment, know each other's roles/responsibilities, strengthen interdisciplinary crossover, pay attention to and support the cultivation of nurses' ability, to promote efficient communication and cooperation among team members.
ABSTRACT
Objective To analyze the main active components and potential molecular mechanism of Sophora flavescens against breast cancer based on network pharmacology and molecular docking. Methods The chemical constituents were collected and screened by TCMSP, ETCM database and literature review. The targets of active ingredients were predicted by Swiss Target Prediction database. Breast cancer-related targets were collected by GeneCards, TTD, Drugbank and OMIM. The anti-breast cancer targets of Sophora flavescens were screened by Venny 2.1.0 software. Cytoscape software was used to construct the network diagram of Sophora flavescens-key active ingredients-targets. STRING database was used to analyze the common targets, and PPI network diagram was constructed. GO function enrichment analysis and KEGG pathway enrichment analysis of key target proteins were performed by DAVID database and Hiplot online platform. Schrodinger software was used to calculate the molecular docking between the active ingredients and targets. Molecular biological methods were used to verify the key targets. Results A total of 36 active components with clear structures were screened from Sophora flavescens. 70 anti-breast cancer targets of Sophora flavescens were screened out. 12 core targets including EGFR, AKT1, ESR1, SRC, CYP19A1, AR and ABCB1 participate in endocrine resistance, EGFR tyrosine kinase inhibitors and estrogen signaling pathways in breast cancer. Moreover, the docking score between the core component and the key target AR is the highest. In vitro experiments showed that the extract of Sophora flavescens can inhibit the proliferation of breast cancer cells, induce cell apoptosis and up-regulate AR protein expression. Conclusion It was revealed that Sophora flavescens plays an anti-breast cancer role by regulating complex biological processes through multiple components acting on multiple targets and signaling pathways. The upregulation of AR protein by Sophora flavescens may become a new therapeutic strategy for the treatment of breast cancer.
ABSTRACT
Objective:To construct and validate a theoretical model of residents′ willingness to participate in tiered medical care based on harmonious management theory, providing reference for promoting the tiered medical care system and aiding governmental decision-making.Methods:Based on the harmonious management theory and literature review, a model capturing residents′ propensity to engage in tiered medical care was formulated. Using convenience sampling method, a questionnaire survey was conducted on 2 067 residents from 24 communities in Zhejiang province from April to May 2022. Descriptive statistical analysis was conducted on the survey results, and multilevel linear regression and structural equation modeling were used to analyze the driving mechanism of residents′ willingness to participate in tiered medical care.Results:The willingness rate of residents to participate in tiered medical care was 69.7%, which was at an average level. Regression insights highlighted the positive influence of policy support perception ( β=0.170, P<0.01), awareness of management mechanisms ( β=0.093, P<0.01), cognitive attitudes ( β=0.102, P<0.01), and trust levels ( β=0.244, P<0.01) on residents′ participation willingness. In contrast, resource allocation perceptions lacked a significant effect ( β=0.065, P>0.05). The structural equation model revealed that cognitive attitudes played a mediating role in the " policy system perception → participation willingness" and " management mechanism perception → participation willingness" pathways, with effect sizes of 0.030 and 0.039, respectively. Trust levels also mediated these paths, with effect sizes of 0.039 and 0.045, and entirely mediated the " resource allocation perception → participation willingness" path, registering an effect size of 0.053. Conclusions:The harmonious management theory can be used to explain the formation mechanism of residents′ willingness to participate in tiered medical care. The government and medical institutions urgently need to further improve residents′ awareness of tiered medical care, focus on enhancing residents′ trust, and further improve policies and management measures such as financial investment, medical insurance reimbursement, and referral systems.
ABSTRACT
Objective:To explore the driving mechanisms of doctors′ collaborative willingness and behavior in the tiered diagnosis and treatment system, in order to provide reference for promoting the construction of the tiered diagnosis and treatment system.Methods:Based on the harmonious management theory, a theoretical framework for the driving mechanisms of doctors′ collaborative behavior in the tiered diagnosis and treatment system was developed. Through random sampling, a questionnaire survey was conducted among doctors from 40 medical institutions in five prefecture-level cities in Zhejiang province between April and May 2022. The t-test, variance analysis, and non-parametric tests were employed to analyze the differences in collaborative willingness and behavior among doctors based on various demographic characteristics. The structural equation model and stratified linear regression were used to assess the impact of collaborative factors (professional environment and work expectations) and harmonious factors (perception of policy support and perception of management mechanism) on doctors′ collaboration willingness and behavior. Results:A total of 1 959 doctors participated in the survey. Doctors′ collaborative behavior scored 2.13±1.12, indicating a slightly below-average level, whereas their willingness to collaborate scored 3.88±0.79, falling between neutral and somewhat willing. Significant differences in collaborative behavior scores were observed based on the medical institution′s ranking, age, years of experience, monthly average income, and professional titles ( P<0.05). Both collaborative and harmonious factors directly influenced the doctors′ willingness to collaborate, with standardized path coefficients of 0.428 and 0.139, respectively. Similarly, these factors directly impacted their collaborative behavior, with standardized path coefficients of 0.104 and 0.366. The perceptions of policy support and management mechanisms demonstrated a significant positive moderating effect on the relationship between doctors′ collaborative willingness and behavior, with effect values of 0.047 and 0.043 respectively ( P<0.05). Conclusions:The collaborative and harmonious elements serve as positive drivers for collaboration among doctors in the tiered diagnosis and treatment system at both the cognitive and behavioral levels. Enhancing and optimizing policy support and management mechanisms can facilitate the transition from intention to actual collaborative actions among doctors from different levels of medical institutions.

ABSTRACT
Based on a sufficient analysis of the theoretical framework of " transformation learning collaboration" ( TLC ) and " people-centered and integrated health care " ( PCIC ) mode, this article introduced the main practices and achievements of " Hangzhou characteristics" countywide medical alliances, centering on TLC mode.Hangzhou takes the countywide medical alliance construction as a pilot, refers to the TLC model, and takes growth-oriented collaboration as the guidance, to promote responsibility sharing, benefit sharing, service integration and management collaboration.Guided by the PCIC model proposed by the World Health Organization, the city has established an integrated service model of hierarchical medical system-prevention-rehabilitation-aging care.The countywide medical alliance system framework features " 5 fields, unified leadership, unified culture, 6 supports, 3 tasks and TLC teams " , which may provide references for the coordinated and integrated development of such alliances.
ABSTRACT
Reform of public hospitals is key to the healthcare system reform.This article introduced how Hangzhou implemented such a reform of " Hangzhou characteristics" by referring to the hospital reform framework of the World Bank, and the theoretical achievements and practical experiences of domestic public hospitals′reform.Led by the service concept of " Medicine has its limitations but we have the courage to overcome, service is boundaryless and we must pursue excellence" , Hangzhou has established a public hospital value system of " reorientation to public welfare".The smart healthcare system serves as a focus, to support the delicacy management of the hospitals. The construction of hierarchical medical care system functions as the pillar, to support the coordinated development of hospitals, primary health institutions and public health institutions.This way a public hospital comprehensive reform mode is established featuring " one value system, 2 levels of organization structure, 6 mechanisms, and 19 supporting measures ". Its experiences may serve as reference to streamline hospital internal operation and external cooperation mechanism.
ABSTRACT
Further healthcare system reform calls for desirable pathway design. This paper introduced the logical framework of the new healthcare system reform pathway design and typical practical experience in Hangzhou.Known for " Internet+Smart healthcare" forerunner, Hangzhou has pioneered the reform of public hospitals and the construction of smart handy service for the public.With the aim of fully protecting the health rights and interests of urban and rural residents, comprehensive policy has been taken to deepen the reform of public hospitals; with the comprehensive promotion of contracted services and the primary level sharing of resources as a carrier, we will build a hierarchical medical service system of vertical linkage.We will also innovate and practice the governing philosophy of " Medicine has its limitations but we have the courage to overcome, service is boundaryless and we must pursue excellence".Promotion of party building in the industry also ranks high.Deepening the reform of " one visit for all" in the field of medical and health services as a measure to enhance people′s sense of gain; The " public-private partnership" to encourage the development of the social governance system and legalization in healthcare proves successful at this stage. However, there are still many challenges in the information security maintenance of smart healthcare, the balance of stakeholder interests in public hospitals, the all-round advancement of hierarchical medical service, standardizing and streamlining the reform of " one visit for all".
ABSTRACT
Objective To measure and analyze the order degree of the internal subsystems and the synergetic degree of the compound system of rural public health service in county areas based on the synergy model of the compound system. Methods According to the distribution of eastern, central and western regions in China, Xiangshan county in Zhejiang province, Wuzhi county in Henan province and Bin county in Shaanxi province were sampled. Based on the index system of synergetic degree measurement including the 52 level-2 evaluation indicators, a questionnaire survey was used to measure the synergetic degree of the compound system of rural public health service in county areas. Results The highest synergetic degrees of the compound system of rural public health service in Xiangshan county, Wuzhi county and Bin county were only 0. 18153, 0. 18068 and 0. 21312 respectively. This indicated the synergy at a low degree. And the synergy of the supply-demand system was an important influential factor for synergy of this compound system, as their development trends were consistent basically. Conclusions The synergy model of the compound system can play a useful role in rural public health service system in county areas. The demand of rural residents deserves more attention and the difference between the service supply and demand should be reduced.
ABSTRACT
Based on synergetics, system theory and dissipative structure theory, the connotation and composition of the compound system of rural public health service in country area are described in the paper. The authors proposed that the synergy degree model of the compound system for rural public health service in county areas comprises the order degree model and the synergy degree model of the compound system, which are composed of such subsystems as functionality, service network, demand, and economy. They also probed into the evaluation method for synergy degree and built the measuring index system of synergy degree comprising 59 level-2 evaluation indicators.
ABSTRACT
Objective To further improve the comprehensive evaluation program of patient satisfaction in view of the defective item screening and weight design short of considerations for patients'psychological expectation and rational judgment, based on the theory of bounded rationality. Methods A satisfaction measurement scale was compiled and used to survey 847 inpatients in July-August 2017. The internal consistency test, correlation and factor analysis were used to evaluate the reliability and validity of the scale. The combination weight PWi was calculated based on patients' importance of the five satisfaction dimensions and the scoring of certainty degree of their responses. The combination weight EWi was calculated based on the five-dimension importance and operability scoring of expert consultation. The indicator combination weight OWi was determined using the integrated factors scoring, TOPSIS, weight rank-sun ratio, gray correlation method, and synthetic index method were used in a general assessment of patient satisfaction of a hospital in question. Results The Cronbach α coefficient of the patient satisfaction rating scale was 0.939, and the half-reliability coefficient was 0.951. The cumulative contribution rate of the five common factors variance extracted from the factor analysis was 71. 4%. The rational weights of five dimensions of service environment, service efficiency, service attitude, service technology, and service costs were 0.220, 0.214, 0.217, 0.179, and 0.171 respectively, while the comprehensive weights of the five dimensions were 0.115, 0.233, 0.196, 0.264, and 0.192 respectively. The comprehensive evaluation results of the two correlation coefficients were greater than 0.95. Conclusions The patient satisfaction measurement scale developed based on the theory of bounded rationality can expand the index connotation and items of core elements such as service technology and cost. The design of index weights fits with the concern of medical service factors and the degree of rational judgment in the patient's medical treatment process. The evaluation results are basically consistent with the actual situation and can be used as a reference tool for the scientific rational evaluation of patient satisfaction.
