4.The correlation of dentofacial structure and the sagittal upper airway size in youthful nonsnoring men with malocclusion
Journal of Practical Stomatology 1996;0(02):-
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.
5.Estrogen receptor expression in genioglossus of ovariectomized rats
Journal of Practical Stomatology 2001;0(03):-
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.
6.Treatment of obstructive sleep apnea using bi-polar radiofrequency and oral appliance
Journal of Practical Stomatology 2000;0(06):-
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.

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.

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.
