ABSTRACT
OBJECTIVE：To construct China ’s Insurance Mode for ADR injury compensation model under marketing authorization holder （MAH）system，and to provide reference for reducing the medical disputes caused by ADR damage and protecting the rights and interests of patients. METHODS ：Using the methods of recommendation and “snowball”，the interviewers were invited to conduct semi-structured interviews to obtain qualitative data ，and the results were analyzed by thematic analysis. According to the results of subject analysis ，the ADR injury compensation model was designed from three aspects of insurance type setting，insurance level division and compulsory insurance protection objects ，and the Fuzzy comprehensive evaluation method based on AHP was used to evaluate the model ；questionnaire and multiple factor Logistic regression analysis was adopted to analyze the influential factors of whether drug related institutions were willing to establish ADR injury compensation system. RESULTS：A total of 40 experts were invited and 34 of them completed the interview ，with a response rate of 85.0％. At present ， the problems of ADR injury compensation in China mainly included the difficulties of third-party identification and adducing evidence of ADR injury ，the difficulty of timely and fair settlement of medical disputes caused by ADR injury ，the high cost and long time of handling ADR injury disputes ，and the uncertainty of compensation mode. More than half of the experts interviewed agreed with the compensation mode of insurance . The overall score of established model was 89.50. A total of 640 questionnaires were distributed and 559 valid questionnaires were recovered （204 drug manufacturers ，172 drug distributors and 183 medical institutions）. The effective rate of the questionnaire was 87.3％. Multiple Logistic regression analysis showed that the factors positively correlated with the approval of establishing ADR injury compensation system after the implementation of MAH system in China included the familiarity of ADR staff in drug manufacturing enterprises with ADR related policies （β＝1.697，P＜0.05），the types of drugs operated by pharmaceutical companies （β＝2.987， P＜0.05），the cognitionlevel of medical staff on ADR （β＝ 2.800，P＜0.05）. The working years of medical staff were negatively correlated with the approval of establishing ADR injury compensation system after the implementation of MAH system （ β ＝－ 2.544，P＜0.05）. CONCLUSIONS ：ADR injury compensation model designed in this study is feasible. It has reference value for reducing the economic burden of ADR patients ， treating patients ’health problems caused by ADR injury in time ，and promoting the development of China ’s drug insurance. Main influential factors for the establishment of ADR injury compensation model under MAH system contain the familiarity of ADR staff in drug manufacturing enterprises with ADR related policies ，the types of drugs operated by pharmaceutical companies ，the cognitionlevel of medical staff on ADR ，the types of drugs operated by pharmaceutical companies ，the cognitionlevel of medical staff on ADR.
ABSTRACT
OBJECTIVE： To provide reference for constructing ADR damage relief system in China. METHODS： Questionnaire survey was conducted among 217 pharmaceutical manufacturers in Shaanxi province by census method. Fisher’s exact test， Pearson χ2 test and multivariate Logistic regression analysis were used to analyze the factors effecting construction of ADR damage relief systerm unter marketing authorization holder （MAH） system， and the interaction among various factors. RESULTS： A total of 217 drug manufacturers were investigated in this study （217 questionnaires were sent out）. 209 questionnaires were collected and 204 valid questionnaires were screened out with recovery rate of 94.01％. Totally 9 independent influential factors screened by Fisher’s exact test and Pearson χ2 test had a significant impact on the attitude of building ADR damage relief system under MAH system， i.e. the last year’s earnings of enterprises， the proportion of pharmaceutical technicians， whether to set up R&D departments， whether to obtain new drugs/generic drugs in recent 3 years， whether to actively carry out post-marketing safety evaluation of drugs， whether ADR commissioners are familiar with ADR-related policies in MAH system， cognition about whether MAH system promotes the development of pharmaceutical industry， the development direction of enterprises after the full implementation of MAH， cognition about the lack of legal basis for ADR damage relief （P＜0.05）. Multivariate Logistic regression analysis showed that whether the ADR specialist was familiar with the ADR-related policies in MAH system was the main influential factor for constructing ADR damage relief system under the MAH system （P＝0.044）. It was positively correlated with the attitude of approving the construction of ADR damage relief system under MAH system （B＝1.697）. CONCLUSIONS： The pharmaceutical manufacturers， in which ADR specialists who are familiar with the ADR-related policies in the MAH system， are more inclined to agree to constructing ADR damage relief system under MAH system.
ABSTRACT
In recent years, the Gut Microbiota-Brain Axis theory has pointed out that there is an interaction between gut microbiota and central nervous system diseases.A number of studies have shown that there is a link between gut microbiota and depression, Parkinson's disease, and Alzheimer's disease.The association between gut microbiota and stroke has also attracted wide attention.This article reviews the association between gut microbiota and stroke.
ABSTRACT
Purpose To evaluate the correlation among diffusion weighted imaging (DWI), tumor Cellularity and hypoxia-inducible factor-1α (HIF-1α) for the high and low grade astrocytoma. Materials and Methods DWI was applied with 33 patients with astrocytoma confirmed by pathology, and ADC value was measured. Tumor Cellularity was measured using Scion Image 4.0.3.2. The expression of HIF-1α was tested using immunohistochemisty. Results Mean ADC value was higher in the low grade astrocytoma than that in the high grade astrocytoma (t=7.300, P<0.001). The tumor Cellularity was higher in the high grade astrocytoma than that in the low grade astrocytoma (t=-3.845, P<0.01). HIF-1αexpression could be demonstrated in the low grade [(20.08±10.01)%] and high grade [(47.91±19.03)%] astrocytoma. The negative correlation was demonstrated between ADC value and HIF-1αand tumor Cellularity (r=-0.756,-0.617;P<0.001). The positive correlation was demonstrated between HIF-1αand tumor Cellularity (r=0.622, P<0.001). Conclusion ADC value can be used to discriminate the low and high grade astrocytoma, and the role of HIF-1αshould be further to study with enlarged sample.
ABSTRACT
Objective To evaluate the implementation of the national essential medicine system in Shaanxi Province.Methods Using a standardized methodology (2008 Edition) developed by the World Health Organization(WHO) and Health Action International(HAD,data on the prices and availability of 38 essential medicines were collected from 120 primary,secondary and tertiary public hospitals in ten cities of Shaanxi Province from March to May 2012.Results The availability of essential medicines is generally low at public hospitals in Shaanxi province,as the average availability of originator brands is but 5.9％,and that of generics of the lowest prices is but 23.9％,while this availability at tertiary hospitals is higher than hospitals of lower levels.The procurement prices of originator drugs within essential medicines are distinctly higher than the international reference prices for the originator brands,and slightly higher for the lowest priced generics.The procurement prices at primary care hospitals are slightly lower than that of other hospitals.Retail prices of essential medicine are not significantly different among regions of different income levels.Affordability of originator brands is poor,while that of their generic equivalents is good.Conclusion The government is recommended to adjust the national essential medicine list,expand the variety of essential medicine moderately,improve the medicine pricing mechanism,and deepen public hospitals reform.
