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 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 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 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 study the development of available space of lower posterior arch. Methods: The sample consisted of 188 randomly selected subjects aged from 11 to 18 years, 76 males and 112 females. The distance from the distal surface of mandibular first molar to the anterior border of the ramus was measured on orthopantomography. All the data were analyzed statistically. Results: 1) The distance(mm) in female and in male was 14.45?3.54 and 13.29?4.17 respectively( P

Objective: To investigate the cephalometric parameters related with anterior overbite. Methods: 144 patients with malocclusion in permanent dentition (74 skeletal Class I and 70 skeletal Class II) were recruited into the study. Cephalometric analysis was performed from pre-orthodontic lateral headfilm in natural head position. Both linear correlation analysis and stepwise regression analysis were respectively performed in the two groups. Results: In the stepwise regression equation of Class I group, the larger the overjet, posterior facial height and upper incisor height, or the smaller the lower facial height and lower molar height, the deeper the anterior overbite was. In the 70 Class II, the larger the overjet, interincisal angle and inclination of lower incisors, or the smaller the mandibular angle and upper molar height, the deeper the anterior overbite was. The equations could explain 75.8% and 62.3% overbite variations, respectively. Of all the parameters, overjet took the most important part in maintaining a normal and stable anterior overbite. Conclusion: Those cephalometric parameters correlated with anterior overbite can be both dental and skeletal. They may compensate each other to maintain stable anterior overbite. Of them, anterior overjet may be the main factor.

ObjectiveTo analyze the causes of and principles for reoperation of congenital choledochal cyst (CCC).MethodsDuring the period of 1986 to 2000, 120 cases of CCC were admitted to our unit,53 of them underwent reoperation. There were 33/14/2/4 cases respectively in Todani Type of Ⅰ/Ⅳa/Ⅳb and Ⅴ. First operation included simple external drainage in 17 cases, choledochoduodenostomy in 8 cases, and choledochojejunostomy with Roux en Y loop in 22 cases etc.ResultsPostoperative complications after external or internal drainage were cholangitis and hepatolithiasis, and high incidence of biliary carcinoma 19% (10/53). The mode of reoperation was mainly cyst excision with Roux Y hepaticojejunostomy (46/53).Conclusions Inappropriate surgical management of CCC incurred much complications that necessitated a reoperation. Cyst excision with reconstruction of the biliary tree by a Roux Y anastomosis is recommended as the therapy of choice for reoperation for patient with CCC.
