RESUMO
OBJECTIVES: Stroke imposes a heavy economic burden and loss of productivity on individuals and society. This study assessed a range of crucial factors, including direct costs and indirect costs, to gauge the economic implications of stroke in China. These outcomes were evaluated with specific reference to the year 2018, using the Chinese yuan (¥) as the unit of measurement and providing the corresponding purchasing power parity dollar ($PPP) currency value. METHODS: A cost-of-illness methodology was used to ascertain the economic implications of stroke in 2018. Within the constraints of this approach, economic costs were defined as 'direct costs' or 'indirect costs'. We estimated direct costs from sample data, the National Health Service Survey and the National Health Account and Health Statistical Yearbook. A human capital method was used to conservatively estimate indirect costs. RESULTS: In 2018, of the economic burden of stroke in China, the direct costs were ¥247.8 billion ($PPP 58.6 billion) and indirect costs were ¥704.4 billion ($PPP 166.5 billion). The curative care expenditure for stroke was ¥193.1 billion ($PPP 45.7 billion), consuming nearly 5.5% of curative expenditure. The cost of stroke treatment relied heavily on public financing, with 58% from social health insurance and 14% from government sources. CONCLUSIONS: A significant economic burden is imposed by stroke on China's economy, and there is a risk of underestimating this burden if indirect costs are not comprehensively considered. The importance of implementing effective preventive measures and screening strategies for stroke, with a particular focus on high-risk populations, is underscored by this study's findings. Such investments in public health have the potential to yield substantial benefits.

Introduction: Depression is the leading cause of disability worldwide and has become a health issue of global concern. Based on the "System of Health Accounts 2011" (SHA 2011) for patients with depression, this paper studies the changes in the current curative expenditure (CCE) of outpatient depression in Liaoning Province, China, and provides policy recommendations. Method: A stratified multistage random sample of 56,994 patients with depression included from 1,227 healthcare facilities in Liaoning Province were included. The significance of differences in variables within groups was analyzed by univariate analysis (including descriptive statistics analysis, Mann-Whitney U test and Kruskal-Wallis H test), and factors influencing depression outpatient CCE were analyzed by multiple linear regression analysis and constructing structural equation models (SEM). Results: The CCE of outpatient depression was ranging from CNY 75.57 million to CNY 100.53 million in 2015-2020, with the highest of CNY 100.53 million in 2018, CNY 103.28 million in 2019. Medical expenditures are mainly concentrated in general hospitals and provincial healthcare institutions, accounting for about 90% of all provincial scope expenditures. The multiple regression results show that provincial healthcare institutions, purchase of drug, select medical treatment for depression, general hospitals and urban employees' health insurance are the main influencing factors for depression outpatient CCE. The results of SEM show that insurance status negative impact outpatient expenditure. Conclusion: Health insurance is an important factor in equitable access to healthcare resources for patients, and medication expenditure is the influential factor affecting the high expenditure of outpatient clinics. It is of great importance to reduce the medical burden of patients by increasing the coverage of medical insurance, increasing the proportion of bills that are eligible for reimbursement, and improving the system by guaranteeing the supply of psychotropic medication.
RESUMO
Polygoni Multiflori Radix (PMR) is a medicinal herb commonly used in China and Eastern Asia. Recently, the discovery of hepatotoxicity in PMR has received considerable attention from scientists. Processing is a traditional Chinese medicine technique used for the effective reduction of toxicity. One uncommon technique is the braising method-also known as 'Wen-Fa' in Chinese-which is used to prepare tonics or poisonous medications. Braised PMR (BPMR)-also known as 'Wen-He-Shou-Wu'-is one of the processed products of the braising method. However, the non-volatile components of BPMR have not been identified and examined in detail, and therefore, the hepatotoxic advantage of BPMR remains unknown. In this study, we compared the microscopic characteristics of different samples in powder form using scanning electron microscopy (SEM), investigated the non-volatile components, assessed the effects of different processed PMR products on the liver, and compared the differences between BPMR and PMR Praeparata recorded in the Chinese Pharmacopoeia (2020 edition). We found that the hepatotoxicity of BPMR was dramatically decreased, which may be related to an increase in polysaccharide content and a decrease in toxic substances. The present study provides an important foundation for future investigations of the processing mechanisms of BPMR.

BACKGROUND: At present, little research concerning the assessment of left atrial (LA) dysfunction in patients with obstructive sleep apnea (OSA) using a combined assessment by speckle tracking (STE) and real-time three-dimensional echocardiography (RT3DE) is available. The objective of this study was to evaluate the LA volume and function by STE and RT3DE in patients with OSA. METHODS: In our cohort study, ninety-two OSA patients and 50 healthy individuals were enrolled. According to the apnea hypopnea index (AHI), patients (AHI >15/h) classified as having moderate and severe OSA were included. The patients were divided into 2 subgroups according to the left ventricular mass index (LVMI): the left ventricular hypertrophy (LVH) group in which patients had LVH (n=30), and the nonLVH group in which patients did not have LVH (n=62). All subjects underwent LA function assessment by conventional techniques and the combination of STE and RT3DE. RESULTS: OSA patients showed impaired LA global longitudinal strain during early diastole (LA S-E) and systole (LA S-S) but increased LA global longitudinal strain during late diastole (LA S-A) compared with controls (all P<0.05). In addition, OSA patients with LVH had lower LA S-S and LA S-E than patients without LVH (all P<0.05). With regard to parameters obtained from RT3DE, indexed LA maximum, minimum, and preatrial contraction volumes (LAVi-max, LAVi-min, LAVi-preA) and the LA active emptying fraction (LAAEF) were significantly higher, whereas the LA passive emptying fraction (LVPEF) was significantly lower in OSA patients in comparison with controls (all P<0.05). The LA total emptying fraction (LVTEF) and the LA expansion index were significantly lower in OSA patients with LVH than in controls (all P<0.05). Additionally, OSA patients with LVH had higher LAVi-min, LAVi-preA and LAAEVi but lower LAPEF than patients without LVH (all P<0.05). CONCLUSIONS: OSA is associated with LA remodeling and dysfunction that occurs in the subclinical stage before the development of LVH and left ventricular diastolic dysfunction, and it will be further aggravated along with the development of LVH and OSA severity. The process can be detected with a detailed evaluation of active and passive functions of the LA using the STE and RT3DE method.

PURPOSE: Adolescent health has been gaining increasing attention in the Sustainable Development Goals era. Data on adolescent health financing are essential for evidence-based policy planning and evaluation. Little is known on national expenditure on adolescent health in China. To inform decision-making on national strategies of adolescent health and development, this study estimated expenditure on adolescent health-care utilization in China and identified funding sources and their allocation among different health functions. METHODS: We constructed and implemented an institutional survey and collected primary financial data from health institutions in the nine selected administrative provinces in 2014. We used the collected data to generate estimate of proportion of health spending on adolescent health and its breakdowns by health-care functions, health-care financing schemes, and diseases based on primary diagnosis. We applied the proportion estimates to the 2014 national-level health expenditure data and estimated national-level estimates of spending on adolescent health and breakdowns in aforementioned areas. RESULTS: Spending on adolescents health in 2014 amounted to CNY82.1 billion (USD 13.4 billion) or 2.6% of the total health expenditures in the year. Per adolescent health expenditures was CNY525 (USD 85.5), less than per capita health spending (CNY2349, USD382.4). National spending on adolescent health was 73.1% on curative care and 10.3% on preventive care. Out-of-pocket spending is the major source of adolescent health financing, contributing to 57.9% of total spending on adolescent health. Spending on respiratory, digestive, injury and poisoning, genitourinary diseases, and neoplasms accounted for 59.8% of curative care expenditures on adolescents. CONCLUSIONS: Current financing mechanism on adolescent health stressed on curative care and imposed a large portion of financial burden on households. Future investment on adolescent health shall focus more on preventive care. Financing schemes shall be adjusted so as to reduce household out-of-pocket spending on medical care used by adolescents.

BACKGROUND: To evaluate subtle and early premature ventricular complex (PVC)-induced ventricular impairment in patients with frequent PVCs and without structural heart disease by real-time 3-dimensional (3D) speckle tracking echocardiography (RT3D-STE). HYPOTHESIS: Patients with frequent premature ventricular complexes with normal left ventricular ejection fraction have subtle left ventricular dysfunction. METHODS: Forty patients (22 male) with a single source of frequent PVCs and 40 healthy controls (24 male) underwent assessment by conventional 2-dimensional (2D) echocardiography and RT3D-STE. Left ventricular ejection fraction (LVEF), and global longitudinal, circumferential, radial, and area strain (GLS, GCS, GRS, and GAS, respectively) and individual segment strain were calculated using off-line analysis software and compared between the 2 groups. RESULTS: There were no significant differences in baseline clinical or 2D echocardiographic variables including LVEF between groups. However, all RT3D-STE assessed variables, including GLS, GCS, GRS, GAS, and individual segment strain, were significantly lower (P < 0.05) in the PVC group than the control group, and showed strong correlations, most prominently GCS (r = -0.84, P = 0.020), with LV function as assessed by LVEF. 3D-STE measurements showed good intraobserver, interobserver, and test-retest agreement. CONCLUSIONS: In patients with frequent PVCs and normal LVEF, 3D -STE revealed lower global and regional strain values than in healthy controls. RT3D-STE is a novel, feasible and reproducible method to assess cardiac function and appears suitable to detect subtle left ventricular dysfunction.

We estimate the distributional incidence of health care financing in 13 Asian territories that account for 55% of the Asian population. In all territories, higher-income households contribute more to the financing of health care. The better-off contribute more as a proportion of ability to pay in most low- and lower-middle-income territories. Health care financing is slightly regressive in three high-income economies with universal social insurance. Direct taxation is the most progressive source of finance and is most so in poorer economies. In universal systems, social insurance is proportional to regressive. In high-income economies, the out-of-pocket (OOP) payments are proportional or regressive while in low-income economies the better-off spend relatively more OOP. But in most low-/middle-income countries, the better-off not only pay more, they also get more health care.
