ObjectiveTo evaluate the clinical efficacy of Fuzheng Huaji Formula （扶正化积方） for chronic hepatitis B to reduce the incidence of liver cirrhosis and hepatocellular carcinoma. MethodsA retrospective cohort study was conducted， collecting medical records of 118 patients with chronic hepatitis B and 234 patients with hepatitis B-related cirrhosis who visited the hospital between January 1， 2014， and December 31， 2018. The use of Fuzheng Huaji Formula was designated as the exposure factor. Patients receiving antiviral treatment for hepatitis B without concurrent Fuzheng Huaji Formula therapy were included in the western medicine group， while those receiving antiviral treatment combined with Fuzheng Huaji Formula for a cumulative treatment lasting longer than 3 months were included in the combined treatment group. The follow-up observation period was five years. Kaplan-Meier survival analysis was used to assess the cumulative incidence of cirrhosis in patients with chronic hepatitis B and the cumulative incidence of hepatocellular carcinoma in patients with hepatitis B-related cirrhosis. Univariate and multivariate Cox regression analyses were employed to examine the factors influencing the occurrence of cirrhosis and hepatocellular carcinoma. ResultsAmong patients with chronic hepatitis B， there were 55 cases in the combined treatment group and 63 cases in the western medicine group； among patients with hepatitis B-related cirrhosis， there were 110 cases in the combined treatment group and 124 cases in the western medicine group. Five-year follow-up outcomes for chronic hepatitis B patients showed that the cumulative incidence of cirrhosis was 5.45% （3/55） in the combined treatment group and 17.46% （11/63） in the western medicine group， with a statistically significant difference between groups （Z = 2.003， P = 0.045）. Five-year follow-up outcomes for hepatitis B-related cirrhosis patients showed that the cumulative incidence of hepatocellular carcinoma was 8.18% （9/110） in the combined treatment group and 22.58% （28/124） in the western medicine group， also showing a statistically significant difference （Z = 3.007， P = 0.003）. Univariate and multivariate Cox regression analyses indicated that treatment with Fuzheng Huaji Formula is an independent protective factor in preventing the progression of chronic hepatitis B to cirrhosis and the progression of hepatitis B-related cirrhosis to hepatocellular carcinoma （P＜0.05）. ConclusionCombining Fuzheng Huaji Formula with antiviral therapy for hepatitis B can effectively intervene in the disease progression of chronic hepatitis B， reducing the incidence of cirrhosis and hepatocellular carcinoma.

Patients with chronic cholestatic liver diseases face numerous challenges in the detection， assessment， and management of suspected drug-induced liver injury （DILI）， and in particular， it is difficult to distinguish cholestatic DILI from the progression of underlying cholestatic liver diseases clinically and histologically. Currently， there is a lack of related research and management guidelines for DILI with chronic cholestatic liver diseases. This article discusses the potential risks， causality， and classification criteria for chronic cholestatic liver diseases with DILI， in order to improve the understanding of such diseases among clinicians and provide a reference for prevention， treatment， and management strategies.

Objective To develop and validate a questionnaire for assessing the synergistic effects of physician col-laboration within a tiered healthcare system,dissect its structural dimensions,and explore the internal logical rela-tionships among these dimensions.Methods Literature review and focus group discussions were employed to clarify the conceptual framework and components of the synergistic effects of physician collaboration in a tiered healthcare system,leading to the development of the questionnaire.Multi-stage sampling was used to survey 1 959 physi-cians.Results The questionnaire for assessing physician collaborative synergy effects consists of four dimensions:col-laborative cognition,collaborative trust,collaborative willingness,and collaborative behavior,comprising 10 items in total.The overall Cronbach's coefficient and the coefficients for four dimensions were all above 0.7.Exploratory factor analysis results extracted four common factors,with a cumulative variance contribution rate of 86.7％.Confirmatory factor analysis revealed that the composite reliability of the four dimensions of the questionnaire was above 0.7,and the average variance extracted was above 0.5.Collaborative cognition influenced collaborative behavior through the chain-mediating roles of collaborative trust and collaborative willingness.Conclusion The developed questionnaire for assessing the synergistic effects of physician collaboration in a tiered healthcare system has good reliability and validity.Its dimensions fit well with the interrelated structure of"knowledge","emotion","intention"and"action",making it a suitable reference tool for evaluating the extent and effectiveness of physician collaboration across different medical institutions within a tiered healthcare system.

ObjectiveTo investigate the effect of Tongxinluo capsules on the use of anti-ischemic drugs in patients with chronic coronary syndrome （CCS） of Qi deficiency and blood stasis. MethodA multicenter，prospective cohort study was conducted，with Tongxinluo capsules intervention as the exposure factor. Patients were divided into an exposed group （combination of traditional Chinese and western medicine） and a non-exposed group （western medicine alone），and followed up for one year. The use of anti-ischemic drugs was observed on the day of enrollment and at 3，6，12 months. ResultA total of 186 patients were enrolled，with 128 in the exposed group and 58 in the non-exposed group. There were no statistically significant differences in baseline characteristics between the two groups. At the 3-month follow-up，the types of first-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01），and this difference remained statistically significant at 6 months （P<0.05） but was no longer significant at 12 months. At the 3- and 6-month follow-ups，there were no significant differences between the two groups in the types of second-line anti-ischemic drugs used. However，at the 12-month follow-up，the types of second-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01）. At the 3-month follow-up，both groups showed a reduction in the types of first-line anti-ischemic drugs used compared to baseline （P<0.05），with a more pronounced reduction in the exposed group （P<0.05）. At the 6-month follow-up，the exposed group showed a significant reduction in the types of second-line anti-ischemic drugs used compared to baseline （P<0.05），while no significant changes were observed in the non-exposed group. At the 12-month follow-up，the difference in the types of second-line anti-ischemic drugs between the exposed and non-exposed groups was statistically significant （P<0.05），while there was no significant difference in the types of first-line anti-ischemic drugs. ConclusionTongxinluo capsules can effectively reduce the use of anti-ischemic drugs in patients with CCS of Qi deficiency and blood stasis.

The tiered medical treatment system stands as a cornerstone in the deepening reforms of China′s medical and health sectors, playing a crucial role in building a healthy China. Exploring the harmonious coexistence mechanism of multiple entities on the supply and demand sides of the tiered diagnosis and treatment system, and promoting the formation of a scientific and reasonable tiered diagnosis and treatment order, has become an urgent public proposition that needs to be answered and has significant social impact. Addressing the challenges in China′s tiered medical treatment system, particularly its need for a more systematic, comprehensive, and collaborative approach, this study is informed by a thorough literature review. Based on the harmonious management and symbiosis theories, the authors proposed a theoretical concept and future research path for the formation of a harmonious symbiotic mechanism in the tiered diagnosis and treatment system, in order to pave the way for exploring the harmonious symbiotic mechanism in the tiered diagnosis and treatment system.

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.

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.

Objective:To analyze the research hot topics, knowledge evolution context, potential frontier trends and future breakthrough directions in the field of medical security governance in China.Methods:Subject term retrieval was used to study the literatures related to medical security governance published by CNKI from January 2009 to December 2021. CiteSpace V software was used to draw the keyword co-occurrence network, time zone map, cluster map, and emergent word graph, and to visually analyze and predict the frontier hotspots and evolution trends in the field of medical security governance.Results:A total of 793 literatures were retrieved. The cooperation network among medical security governance research institutions in China needed to be strengthened; the mainstream of research focused on basic research on medical insurance system design, research on medical security governance paths and methods, and empirical research combined with the era background or policy hotspots.Conclusions:There are some problems in the current rerearch on medical security governance, such as imperfect theoretical construction, research content to be expanded, insufficient communication and cooperation, etc. Future research hotspots tend to be innovation of the goal, structure and path of medical security governance, application of big data in the field of medical security governance, and research on crisis response and challenges of medical security governance under public health emergencies. Future research should strengthen multi-cooperation to jointly tackle key problems, pay attention to the cross-integration of disciplines, develop localized medical security governance innovation systems and mechanisms, and enrich problem-oriented empirical research.

Background::Previous studies have shown that inflammation plays an important role in intracranial atherosclerotic stenosis (ICAS). The platelet-to-lymphocyte ratio (PLR) has recently emerged as a potential inflammatory biomarker. This study aimed to explore the association of the PLR with ICAS in a Chinese Han population.Methods::A total of 2134 participants (518 with ICAS, 1616 without ICAS) were enrolled in this study. ICAS was defined as atherosclerotic stenosis >50% or the occlusion of several main intracranial arteries. Multivariable logistic regression analyses were used to assess the association of the PLR with ICAS. Additional subgroup analyses were performed according to age (<60 vs. ≥ 60 years) and acute ischemic stroke. Results::Multivariate regression analysis showed that a high PLR was associated with a higher risk of ICAS in all participants ( P < 0.001). Compared with the lowest quartile, the fourth PLR quartile was significantly associated with ICAS (OR 1.705, 95% confidence interval 1.278–2.275, P < 0.001). In the subgroups stratified by age, an association between the PLR and ICAS was found in the late-life group ( P < 0.001), but not in the mid-life group ( P = 0.650). In the subgroups stratified by acute ischemic stroke, the relationship between an elevated PLR and a higher risk of ICAS remained unchanged (stroke group, P < 0.001; non-stroke group, P = 0.027). Conclusions::An elevated PLR was associated with a higher risk of ICAS in a Chinese Han population. The PLR might serve as a potential biomarker for ICAS in the elderly population.

Objective: Based on the KAP and Prospect theory, to explore, construct and verify the theoretical model and formation mechanism of driving factors of primary care doctors′ willingness to carry out the primary diagnosis. Methods: Using the random cluster sampling method, from April to May 2019, a questionnaire survey was conducted among doctors at 20 primary medical and health service institutions in Hangzhou. The survey covered the primary care doctors′ cognition level of primary diagnosis, their self-evaluation of primary medical care capabilities, evaluation of policies and systems, expectation of primary medical care, and their job satisfaction. Descriptive statistic, multiple linear regression and structural equation model were used to analyze and explore the driving factors and formation mechanism of their willingness to carry out the primary diagnosis. Results: Primary care doctors′ willingness rate for primary diagnosis was 76.4%(308/403). Positive expectation(beta=0.309), cognition level(beta=0.216), evaluation of policies and systems(beta=0.184), and self-evaluation of primary diagnosis capability(beta=0.170), all of which directly affect the said willingness. The total effect of the five types of driving factors on the willingness of the primary diagnosis was as follows: cognitive level of the primary diagnosis(0.536), evaluation of the policy system(0.494), self-evaluation of the primary diagnosis capability(0.436), positive expectations of the primary diagnosis work(0.186), job satisfaction(0.146). Conclusions The cognition of the primary diagnosis, the capability of the primary diagnosis, the policy system and the positive expectation are the important premises, key driving forces, and a strong guarantee and motivation to drive primary care doctors to carry out the primary diagnosis. It is suggested that the government and medical institutions should further improve the cognition level of primary care doctors, focusing on systematically improving the service capability of primary care doctors′ primary consultation, coordinating to improve policy guidance measures such as financial input, medical insurance reimbursement and referral system, establishing and improving incentive measures such as career development, performance appraisal, salary and welfare of primary care doctors.
