Objective:To investigate the health resources utilization efficiency from the perspective of the end-of-life medical costs in advanced cancer patients,estimate the method of calculating the price range for medical service package in community health service center.Methods:Taking the medical cost of cancer patients in final year of the end of life in Hubei under the dual-referal policy of high leveled hospitals and community medical institutions,it estimated the pricing range for palliative care medical package and designed the medical payment policy for hierarchy diagnosis.Results:With the new medical service package policy,maintained the same level of medical service quantity,the total medical cost would save a great amount.Conclusion:Based on the accurate budget calculation of end-of-life costs,it had great significance for the implementation of classified diagnosis policy,rationally design the link and pricing range between hospitals and community medical service package.

Objective:To explain the supplier induced demand theory paradigm,track the empirical research progress,so as to provide references for health care reform in China.Methods:The new classical theory,game theory and behaviorism school were launched to process theoretical derivation of induced demand.The classical empirical research and the latest research progress were introduced to systemically review on supplier induced demand.Results:The generation of supplier induced demand was related with incentive system,the type of diseases and the crowd of research.Conclusion:It could effectively reduce the induced demand for health care that constraining hospital internal incentive,conducting medical supply side structural reform,developing the “Internet +medical” and building Diagnosis Related Groups (DRGs) payment system.

Objective:To investigate the expression of estrogen receptor in genioglossus of female rats. Methods:30 female Sprague-Dawley rats were randomly assigned to three groups: normal group(NORMAL), sham operation group (SHAM) and ovariectomized group(OVX). The rats were sacrificed 6 weeks after surgery, and the genioglossus was removed for analysis. The expression of estrogen receptors(ER? and ER?) was examined by immunohistochemical assay. Results:ER? and ER? were found in genioglossus of normal rats. The expression of ER? was significantly higher than ER? (P0.05). Conclusions:Estrogen receptors are expressed in genioglossus of female rats.ER? expression is significantly impacted by the estrogen level.

0.05); while in the androgen group, SR Ca 2+-ATPase activity [22.91 ? 4.56 ?mol Pi/(mg protein?hour)] was reduced to 67% (P

Objective: To evaluate the effects of the combined radiofrequency (RF) with oral appliance (OA) therapy on obstructive sleep apnea(OSA). Methods: 15 patients with OSA were diagnosed by overnight monitoring of polysomnography(PSG).They all received bi-polar radiofrequency treatment on palate twice.Polysomnography were taken for the patients 6 weeks after the second RF treatment. 10 cases without TMJ disease and periodontal disease with more than 10 teeth on each of maxillae or mandibulae were treated with OA. Reexamination of PSG was taken one month after application of OA.Statistic analyses were made in the measurements of PSG. Results:PSG measurements showed sleep improvement after treatment(P

Objective:To investigate the correlation of dentofacial structure and the sagittal size of the upper airway in youthful nonsnoring men with malocclusion.Methods:Lateral cephalometry was carried out in 52 nonsnoring males with malocclusion. The average age of the patients was 19.23 years, with a range of 18 to 24 years. Stepwise regression analysis was used to relate those cephalometric parameters to the sagittal airway size at different levels.Results:SNB angle,S-N length and H-C_3 length were the related variables to superior posterior airway space(SPAS). H-C_3 length,SNB angle and L1-MP angle were the related variables to middle airway space(MAS). SNB angle,H-C_3 length,S-N length and L1-MP angle were the related variables to inferior airway space(IAS).Conclusion:The sagittal upper airway size in youthful nonsnoring men with malocclusion is correlated to the dentofacial structure and the hyoid position.

Objective To investigate the changes of soft and hard tissues after extraction space closure with micro-screw implant as orthodontic anchorage. Methods Twenty cases were selected randomly with the first premolars extraction. Micro-screw implant was used as orthodontic anchorage. Sliding technique was used to close the extraction space. The lateral cephalograms before and after the treatment were evaluated.Results The upper incisors moved 7. 15 mm palatelly, 1. 63 mm intruded. The upper first molar moved 0. 80 mm distally, 1. 80 mm intruded. The lower incisors moved 4. 65 mm distally, 0.48 mm extruded. The lower first molar moved 0. 18 mm mesially, 1.18 mm extruded. A point, B point, upper lip, lower lip showed distal movement. Conclusions Micro-screw implant can provide acceptable and reliable anchorage in the process of extraction space closure, and improve the profile. Besides, it produces skeletal change on the maxilla.

Objective:To examine the relation between the alteration of condylar endochondral in response to mandibular protrusion and the action time length by establishing a model of mandibular protrusion on young adult rats. Methods: 75 female Sprague-Dawley rats aged 9 weeks were divided into two experimental groups and one control group. In two experimental groups, bite jumping appliances created forward positioning of the condyle for twelve hours and whole day, respectively. The experimental rats, together with the control rats, were sacrificed on days 3, 7, 14, 21 and 30, respectively. Tissue sections were cut in the sagittal plane through the mandibular condyle and were processed for in situ hybridization and immunostaining of type X collagen. Results: The peak of type X collagen protein expression in 24-hour experimental groups appeared on day 21 which was on the top of all experimental groups, while in 12-hour experimental groups it was found on day 30. The results of in situ hybridization were basically in agreement with the results of immunostaining. Conclusion: Both intermittent and continuous mandibular advancement can provoke endochondral ossification in young adult rat condylar, while 24-hour ones can produce more obvious and quicker effect.

Objective:To investigate the effects of extraction orthodontic treatment on the upper airway dimensions in young adult patients with malocclusion,and to evaluate the relationship between changes in the craniofacial morphology,position of incisor and upper airway dimensions.Methods:26 patients with upper and lower first premolar extraction and 21 patients without extraction were recruited.Cephalometry and dental cast analysis were performed pretreatment and posttreatment.Results:No statistical difference was found in the parameters of the upper airway dimensions in both non-extraction group and extraction group after treatment.In linear correlation analysis,SPAS was positively correlated with cephalometric variables U1-Y and L1-Y.MAS and IAS was positively correlated with cephalometric variables SNB,U1-Y and L1-Y.The multiple regression analysis revealed that the change of U1-Y had a significant positive effect on SPAS and IAS,and the change of L1-Y also had a significant positive effect on SPAS and MAS.Conclusion:The upper airway dimensions can not be altered during extraction orthodontic treatment,while the changes of incisors are significant associated with the change of the upper airway dimensions.
