1.Can prepayment reform of medical insurance control the rise of medical expenses in China? Empirical analysis based on PSM model and CHARLS data
Chinese Journal of Health Policy 2017;10(9):22-31
At present, China's medical service costs keep rising, and residents' out-of-pocket medical expen-ses are also increasing heavily. The prepayment reform of medical insurance is considered as an important starting point to solve the problem. It is of great significance to evaluate the effect of prepaid medical insurance reform on con-trolling medical expenses and reducing economic burden when sick. In order to achieve the objective of this study, a use of CHARLS data 2011 &2015 and DIDPSM theory, and a combination of the Interaction Item Model and PSM model, and make use of a natural experiment developed from experimental reform stage for the comprehensive promo-tion stage of new rural cooperative medical system (NCMS) in 2012, were very crucial. This paper finds that:(1) Prepayment system can control the rise in outpatient and inpatient expenses. Compared with those who did not partici-pate in NCMS in the initial stage of reform, after the universal reform, outpatient and inpatient expenses dropped by 6. 3% and 41%, the average decrease was 1041yuan and 2895yuan, respectively. (2) After the universal reform, the insured patients' medical burden of outpatient and inpatient reduced by 17% and 33%. Prepayment system has, to some extent, resisted the rise in medical expense, and alleviated the burden of medical treatment. (3) On the basis of PSM, the estimated value and significance of coefficients have not changed, the effect of PPS reform is good. The poli-cy implication is that accelerating the prepayment system reform is the key way to control the growing medical expenses.

Objective: To investigate whether grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) can alleviate cognitive decline and other pathologic features in early-stage Alzheimer disease (AD) using transgenic mice with 5 familial AD mutations (5XFAD). Methods: The genotype of transgenic mice was detected by polymerase chain reaction. A total of 40 transgenic mice (1.5 months old) were randomly and equally allocated to an AD model group (5XFAD group) or a grain-sized moxibustion group (5XFAD + GM group), with 20 wild-type (WT) mice (C57BL/6J) serving as the normal control group (WT group). Mice in the 5XFAD + GM group were treated by grain-sized moxibustion at bilateral Xinshu (BL15) and Shenshu (BL23). Mice in the WT group and 5XFAD group received no treatment but were restrained to ensure exposure to a similar experimental condition. Cognitive function and memory were assessed with the Morris water maze and Y-maze tests. The amyloid β 40 (Aβ40) and amyloid β 42 (Aβ42) levels in the brain were evaluated by enzyme-linked immunosorbent assay; amyloid plaque deposition in brain tissue sections was detected by thioflavin-S staining; the expression of glial fibrillary acidic protein (GFAP), cluster of differentiation 11b (CD11b), brain-derived neurotrophic factor (BDNF), and choline acetyltransferase (ChAT) in the hippocampus and prefrontal cortex was analyzed by immunohistochemistry. Results: In the Morris water maze test, compared with the 5XFAD group, mice in the 5XFAD + GM group had a shorter escape latency and more target area crossings and spent more time in the target quadrant (P<0.05). In the Y-maze test, compared with the 5XFAD group, the number of training times of the 5XFAD + GM group was significantly decreased (P<0.05), together with more correct responses (P<0.05). Compared with the 5XFAD group, the levels of Aβ40 and Aβ42 in the brain tissue of the 5XFAD + GM group were significantly lower (P<0.05); in the hippocampus and prefrontal cortex, the total number of amyloid β plaque deposition were significantly lower (P<0.05); the expression levels of GFAP and CD11b were significantly reduced (P<0.05); and the expression levels of ChAT and BDNF were significantly increased (P<0.05).Conclusion: Grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) greatly improves learning and memory functions, decreases the levels of Aβ40 and Aβ42, inhibits amyloid β plaque deposition, decreases the expression of GFAP and CD11b, and increases the expression of ChAT and BDNF in AD mice to inhibit the progression of AD.
