ABSTRACT
Objective:To construct an evaluation index system of perceived service quality for Internet hospitals, and to provide references for scientific evaluation and effective management of such hospitals′ service quality.Methods:Thanks to literature review and expert interviews, an index system was initially built based on the Brady and Cronin model.From August to November 2021, Delphi expert consultation method was used in three rounds of correspondence questionnaire survey, and experts were consulted to assess the importance, familiarity and judgment basis of these indexes. The importance of the indexes was expressed by ± s, and the weight value of each index was calculated using analytic hierarchy process fuzzy comprehensive evaluation method and SPSS Au software. Results:The evaluation index system of perceived service quality for such hospitals included 3 level-1 indexes, namely environmental quality, interaction quality and result quality; and 10 level-2 indexes, namely software platform, service support, social factors, attitude, behavior, professional quality, service effect, service efficiency, service cost, satisfaction; and 30 level-3 indexes. Among these indexes, result quality of level-1 indexes scored the highest weight value(0.337); Software platform, professional quality, service support and attitude of level-2 indexes scored a higher weight values, respectively 0.119, 0.119, 0.109 and 0.109. Of level-3 indexes, reputation of Internet hospitals, service attitude of their doctors and doctor-patient communication skills of doctors online scored a higher weight values, respectively 0.102, 0.057 and 0.055.Conclusions:The index system for Internet hospital perceived service quality evaluation built in this study proved scientific, contributing positively to guiding Internet hospitals to improve their quality and safety management.
ABSTRACT
The positive interaction between medical treatment system and medical insurance system is of great significance to promote the reform of medical and health care system. Due to the complexity of the relationship between them, it is difficult to explain it comprehensively with a single theoretical method. The authors analyzed the relationship between medical treatment system and medical insurance system by applying system theory, game theory and synergy theory, and then put forward policy suggestions to optimize the linkage reform of medical treatment system and medical insurance system, so as to better promote the reform of " three medical linkage" and promote the construction of healthy China. The suggestions included optimizing the allocation of health resources, accelerating the construction of medical insurance legislation and health technical evaluation system, strengthening the construction of multi-level medical insurance system, promoting the inter regional information interconnection between medical care and medical insurance, improving the coordination mechanism, negotiation mechanism, incentive and constraint mechanism between medical care and medical insurance.
ABSTRACT
ObjectiveTo evaluate the clinical benefits of early right median nerve electrical stimulation on coma patients following craniocerebral trauma. MethodsCraniocerebral trauma patients with up to two weeks of coma in the years 2005-2011 were involved in the study and were randomly divided into control group (received routine management ) and treatment group (routine management plus right median nerve electrical stimulation).The treatment lasted for a period of more than two weeks.The clinical efficacy of the right median nerve electric stimulation and the conscious status of the patients within six months after craniocerebral trauma were observed.ResultsA total of 456 patients were enrolled in the study,of whom 437 patients completed the treatment course,including 221 patients in the treatment group and 216 in the control group.There was no complication related to electric stimulation during the treatment.Cerebral blood flow (CBF) imaging and brain stem evoked potential (BEP) examination demonstrated significant improvement in the treatment group.A total of 386 patients were followed up for six months postoperatively,which showed that there were 122 patients with regained consciousness,46 in minimally conscious state and 36 in vegetative state in the treatment group (204 patients) and there were 84 patients with regained consciousness,40 in minimally conscious state and 58 in vegetative state in the control group ( 182 patients).The patients in the treatment group showed a higher ratio of regained consciousness and a lower ratio of vegetative state compared with the control group,but the ratio of minimally conscious state showed no statistical difference between two groups. ConclusionsRight median nerve electrical stimulation is a suitable coma awaking means at early stage after craniocerebral trauma.
ABSTRACT
Objective To investigate the therapeutic effect of NSR siRNA on nerve regeneration following spinal cord hemi-transsection injury in rats. Methods Rats with T8 spinal cord hemi-trans-section were didded into 3 groups, ie, siRNA group, NS group and control group. SiRNA or NS was in-jected into lateral cerebral ventricle just after spinal cord injury. The therapeutic effect of NgR siRNA was evaluated by using BBB locomotor rating scale, retrograde horseradish peroxidase(HRP)tracing and HE staining. Results BBB locomotor rating scale showed that the recovery of the locomotor function of siRNA group seemed to be better than that of the other two groups from the 4th week, but there was no statistical difference. Retrograde HRP tracing showed a large number of positive cells in the anterior horn of spinal cord, with statistical difference compared with NS group and control group(P<0. 05). Eight weeks after spinal injury, HE staining showed disorderly distribution of the fibres in NS group and control group but serial fibres in the injury region in siRNA group. Conclusion NSR siRNA may promote the nerve regeneration following spinal cord injury.
ABSTRACT
Objective To set up a rat model with acute traumatic coma and identify the variation of microRNA in mesencephalon. Methods After rats were injured moderately by central fluid percussion system, tissues of the mesencephalon were removed one hour after injury. RNA of brain tissue of the mesencephalon was isolated for microRNA array by using the exiqon microarray system. The data were analyzed statistically by Genepix Pro 6.0 after hybridization results were scanned and fluorescence intensity standardized. Resets Hybridization results showed 33 microRNAs with up-regulated expressions but 38 microRNAs with down-regulated activity. Conclusion Expression of microRNA array shows marked changes in the tissues of the mesencephalon in rats with traumatic coma, as may be injury mechanism of traumatic coma and also a way of neurobiological protection of coma.
ABSTRACT
Objective To screen the altered gene expression profile of hippocampus after traumatic brain injury(TBI)in rats. Methods Rats(n=3)in experimental group underwent moderate fluid-percussion(F-P)brain injury and the hippoeampus sample in the injured hemisphere was removed and conserved in liquid nitrogen three hours later.The rats(n=5)of the control group underwent the same procedure except for injury.Mfymetrix rat genome 230 2.0 array was used to detect the gene expression profile of hippocampus in two groups and find the altered gene expression profile. Results A total of 159 genes in the experimental group changed significantly(≥2 folds)compared with the control group,of which 136 genes were up-regulated and 23 genes down-regulated. Conclusions The significant gene expression changes of hippocampus,especially a large mount of up-regulated genes,are detected after moderate TBI in rats,suggesting that the secondary injury following TBI is a procedure involving multiple factors.
ABSTRACT
OBJECTIVE: To study the effect of hyperventilat ion on brain tissue oxygen pressure (P(ti)O(2)), brain tissue carbon dio xide pressure (P(ti)O(2)), pH value and intracranial pressure (ICP) dur ing intracranial hypertension in pigs. METHODS: Autologous arterial blood (5.5 mlplus minus0.5 ml) was injected into the left frontal lobe by micropump to establish the model of intr acerebral hematoma in pigs. After blood injection, the animals were hyperventila ted for 15 minutes to decrease the pressure of carbon dioxide in arterial blood (P(a)CO(2)) to 27.35 mm Hgplus minus11.97 mm Hg (1 mm Hg=0.133 kPa). The mean arterial pressure (MAP), intracranial pressure (ICP), cerebral perfusion pressure (CPP), P(ti)O(2), (P(ti)CO(2)), pH value and [HCO(3)(-)] were continuously monitored and the blood gas was analyzed. RESULTS: After hyperventilation, the ICP significantly decr eased (P<0.01), the CPP significantly increased (P<0.05), while the P(ti)O(2) greatly decreased to t he ischemic level (8.20 mm Hgplus minus2.50 mm Hg) (P<0.01), the P(ti)CO(2) decreased (P<0.01) and the pH value increased (P<0.01). At the same time, bl ood gas analysis showed that the P(a)CO(2) greatly decreased and the pH valu e increased. CONCLUSIONS: Hyperventilation can decrease the ICP and the P(ti)O(2) significantly. Therefore, hyperventilation should be avoided earl y after brain injury. The P(ti)O(2) monitoring will be helpful for detec ting cerebral ischemia early.
