Enlightenment of the DRG payment reform in the United States on the reform of China′s medical insurance payment methods / 中华医院管理杂志

In order to curb the excessive growth of medical expenses, the United States has initiated payment reform of diagnosis-related groups (DRG) since 1983, and developed a series of complementary measures to address issues such as overcoding and declining healthcare service quality which were exposed during the reform. The authors discussed the implementation of DRG payment reform in the United States, namely the case-mix specialization of medical institutions and the reduction of costs, as well as the relationship between the two. On this basis, the authors suggested that when implementing reforms to the medical insurance payment system in China, it is imperative to avoid such loopholes as overcoding by medical institutions and excessive pursuit of efficiency at the expense of quality control, as well as the decline of comprehensive rescue capability and quality of care incurred by the exacerbated specialization.

Effect of naringenin on the anti-inflammatory, vascularization, and osteogenesis differentiation of human periodontal ligament stem cells via the stromal cell-derived factor 1/C-X-C motif chemokine receptor 4 signaling axis stimulated by lipopolysaccharide / 华西口腔医学杂志

OBJECTIVES@#This study aimed to investigate how naringenin (Nar) affected the anti-inflammatory, vascula-rization, and osteogenesis differentiation of human periodontal ligament stem cells (hPDLSCs) stimulated by lipopolysaccharide (LPS) and to preliminarily explore the underlying mechanism.@*METHODS@#Cell-counting kit-8 (CCK8), cell scratch test, and Transwell assay were used to investigate the proliferation and migratory capabilities of hPDLSCs. Alkaline phosphatase (ALP) staining, alizarin red staining, lumen-formation assay, enzyme-linked immunosorbent assay, quantitative timed polymerase chain reaction, and Western blot were used to measure the expression of osteopontin (OPN), Runt-related transcription factor 2 (RUNX2), vascular endothlial growth factor (VEGF), basic fibroblast growth factor (bFGF), von Willebrand factor (vWF), tumor necrosis factor-α (TNF-α), and interleukin (IL)-6.@*RESULTS@#We observed that 10 μmol/L Nar could attenuate the inflammatory response of hPDLSCs stimulated by 10 μg/mL LPS and promoted their proliferation, migration, and vascularization differentiation. Furthermore, 0.1 μmol/L Nar could effectively restore the osteogenic differentiation of inflammatory hPDLSCs. The effects of Nar's anti-inflammatory and promotion of osteogenic differentiation significantly decreased and inflammatory vascularization differentiation increased after adding AMD3100 (a specific CXCR4 inhibitor).@*CONCLUSIONS@#Nar demonstrated the ability to promote the anti-inflammatory, vascularization, and osteogenic effects of hPDLSCs stimulated by LPS, and the ability was associated with the stromal cell-derived factor/C-X-C motif chemokine receptor 4 signaling axis.

Application status and suggestions of obstetric intelligent medical service system / 中华医院管理杂志

By leveraging information technologies such as the internet, the internet of things and artificial intelligence, the data-driven intelligent medical service system for obstetrics is an important means to alleviate the uneven distribution of obstetric medical resources, improve service efficiency and reduce medical costs. In recent years, the application advantages of the obstetric intelligent medical service system in maternal health monitoring, health education and remote consultation had gradually emerged, which could effectively improve pregnancy outcomes and improve the utilization of medical resources. Given the significant advantages of the system in convenience, accessibility and interactivity, it is also challenged in such aspects as imperfect application system, poor information security, imperfect policy system and uneven smartness among regions. Therefore it is necessary to further protect maternal and infant safety, promote system upgrading, improve the policy system, promote regional layout balance, and improve medical insurance payment system.

Medical disputes analysis based on DRGs mortality risk ranking / 中华医院管理杂志

Objective@#To analyze cases in different groups of DRGs mortality risk ranking regarding overall medical dispute cases of the hospital from 2012 to 2017, and to study various groups of such ranking for these disputes as faced by different clinical departments, for the purpose of targeted intervention into medical risk exposures.@*Methods@#Inpatient medical dispute cases in 2012-2017 period were selected, and classified into the various mortality groups by the standards and definition of BJ-DRGs. These data were used to calculate medical dispute incidence in each group, and analyze the difference between internal medicine and surgery departments.@*Results@#Medical disputes of the hospital were mostly found in case groups of mortality free and those of low mortality risks, accounting for 66% of the total cases. This figure was the highest in surgical departments, having a percentage as high as 72%, and the CMI values of these cases were low as well (0.765 and 1.416 respectively).@*Conclusions@#As case groups of mortality free and low risks tend to attract disputes, the hospital is recommended to enhance the risk awareness and training of its medical staff and key medical regulations.
