BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.

Engaging in physical activity was proved to have positive effects on physical and mental health in children. Built environment is an important correlate of physical activity participation. School recess provides a daily opportunity for children to be active during school day. Therefore, the purpose of the present article was to review literatures regarding 1) physical activity during school recess, 2) the relationship between recess physical activity and school physical environment, 3) intervention for physical activity promotion during recess by changing school physical environment, and to explore trends of current researches and assignments of future research. A review was conducted and included studies published to May 31, 2011. Twenty-two studies were selected in 1) and showed boys often engaged in more physical activity than girls, but the results on differences in physical activity between ages were inconsistent. Six studies were selected in 2) and indicated recess physical activity was associated with playground environments such as equipments, marking, and surface situate. School environment intervention was observed to be a potential method for promoting physical activity in children by 8 studies in 3). Playground environment with marking, additional play equipments, and designated activity zones increased physical activity during recess. Most researches regarding recess physical activity was conducted in U.S., Australia, and Western countries, and confirmed the effectiveness of recess to promote physical activity. However, few studies on this topic were conducted in Japan. Further researches are needed to draw a conclusion about the possibility of recess to promote physical activity among Japanese children.

Results There were significant increases in the length, anteroposterior diameter and thick-ness of maxillary sinus (P<0.05), while there was no significant differences in the site and central point of maxillary sinus(P>0.05). Conclusions It is a effective approach to change the hard tissue after ortho-dontic treatment for Angle's class Ⅲ malocclusion adolescence patient with front traction in maxillary area.

OBJECTIVETo establish the rat model of acute pulmonary embolism, and study the changes of vascular active substances in pulmonary embolism rats, and investigate the interventive effect of anticoagulant drugs on vascular active substances.

METHODSOne hundred and twenty-eight rats were randomly divided into four groups: control group, model group, low-molecular-weight heparin and warfarin treated group and rivaroxaban-treated group (n = 32 in each group). The method of autologous thrombosis was used to establish the animal model of acute pulmonary embolism. The animals were treated with saline or different anticoagulant drugs. The physiological and biochemical parameters were detected at different time points after embolization. The rats were killed after embolism of 24 h, 3 d, 5 d or 1 week respectively and the pathologic samples of lung tissues were collected to analyze the pulmonary pathological changes in different groups.

RESULTSRats in embolization group after blood clots injection showed shortness of breath, oral cyanosis; quicken heart rates and other symptoms. All embolization groups had pulmonary hypertension, the levels of type B natriuretic peptide (BNP) were increased significantly. The ratio of endothelin-1 (ET-1)/NO and thromboxane (TXB2) and prostacyclin (6-k-PGFla) were abnormal. After treated with effective anticoagulant drugs, the levels of BNP, ET-1, NO, TXB2 and 6-k-PGF1a were tended to the normal levels in the control group. The pulmonary hypertensions were gradually decreased. The efficacy of rivaroxaban on pulmonary embolism was the same as that of the low molecular weight heparin or warfarin.

CONCLUSIONAnticoagulation therapy can effectively improve endothelial function after pulmonary embolism, reduce pulmonary hypertension, and revise the increased BNP levels to normal levels. The efficacy of rivaroxaban is not inferior to that of low molecular weight heparin and warfarin.

BACKGROUND:Distraction osteogenesis applied in patient’s canine distal movement, can greatly improve the speed of tooth movement, and protect the molar anchorage. But the researches on the traction rate, canine pulp vitality, canine periodontal tissue remodeling and the biological mechanisms of the technology are rare recently. OBJECTIVE:To evaluate the feasibility of rapid canine retraction through distraction osteogenesis of the periodontal ligament in adult patients and to monitor the pulp vitality, root resorption and periodontal remodeling of the canine. METHODS:Nine malocclusion patients were selected, and the bilateral maxil ary canine in adult patients were rapidly retracted and moved to the scheduled position using modified distraction devices. The canine distal movement distance, anchorage loss, root resorption and alveolar interval alterations were measured through intraoral radiographs, and lateral cephalograms. The pulp and periodontal of canine were mointrored. RESULTS AND CONCLUSION:The canines could be rapidly retracted to the schedualed position through distraction osteogenesis of the periodontal ligament in 12-16 days, the average amount of retraction was 7.18 mm and the canines tipped distal y (13.24±2.87)°. The anchorage loss was 0.5 mm. There was no obvious root resorption and periodontal tissue loss. The pulp vitality of the canines was decreased significantly right after distraction, but it recovered significantly after 3 months. The results indicated that periodontal ligament distraction osteogenesis can significantly accelerate canine movement speed, shorten treatment time, while protecting the molar anchorage;there was no significant adverse reaction of root resorption, loose teeth, pulp necrosis and loss of periodontal tissue. Indcating that distraction osteogenesis of periodontal ligament can move canines rapidly and effectively.

BACKGROUND: Decompression-internal fixation is needed in the treatment of atlantoaxial dislocation accompanying with spinal compression caused by cranium-neck junction area malformation and other diseases.Different internal fixation methods are chosen according to different conditions, including anterior atlantoaxial internal fixation, posterior atlantoaxial internal fixation or occipitocervical internal fixation. Transoralpharyngeal atlantoaxial plate internal fixation is a method for atlantoaxial anterior fixation. It is developed recently and used for difficult and complicated atlantoaxial dislocation induced by congenital disease, trauma or rheumatoid arthritis.OBJECTIVE: To probe into the clinical application of transoralpharyngeal atlantoaxial reduction plate system in the atlantoaxial dislocation caused by obsolete odontoid fracture.DESIGN: Single Sample observation SETTING: Department of Orthopaedics, Guangzhou General Hospital of Guangzhou Military Medical University of Chinese PLA PARTICIPANTS: Twelve patients with atlantoaxial dislocation caused by obsolete odontoid fracture were selected in the Department of Orthopaedics, General Hospital of Guangzhou Military Medical University of Chinese PLA from January 2003 to October 2005. Among them, 7 were male and 5 were female, they were aged 47 years on average ranging from 36 to 59 years. The mean injured time was 19 months ranging from 4.5 to 36 months; 6 patients were graded as C degree, 3 as D degree and 3 as E degree in Frank gradation.METHODS: Twelve obsolete odontoid fracture caused by atlantoaxial dislocation underwent transoralpharyngeal anterior decompression. Transoralpharyngeal atlantoaxial reduction plate system was used in reduction and fixation. Autogeneic ilium was implanted into bilateral articulatio atlantoepistrophica.MAIN OUTCOME MEASURES: ① Frank gradation of patients at the 4th week after operation. ② whether the internal fixation is loose or not after operationRESULTS: ①Frank gradation at the 4th week after operation: Among the 6 patients who were primarily graded as C degree, 4 patients improved to be E degree and 2 patients D degree; Three patients who were primarily graded as D degree all improved to be E degree; Patients who were primarily graded as E degree did not changed. ② Except for one patient who suffered dislocation again for loosening of screw caused by tumble, the other patients had firm fixation, ideal fusion and satisfying spinal decompression.CONCLUSION: Transoralpharyngeal atlantoaxial reduction plate system finishes atlantoaxial reduction and fixation once. It avoids conducting posterior fusion fixation operation after anterior decompression. It also avoids fetal injury for spinal cord caused by extreme atlantoaxial unsteadiness in the process of movement and turning over.

OBJECTIVEThe sex therapy is not yet popularized at present. This study aimed to evaluate the effect of the combination of the improved sex therapy and oral sildenafil on erectile dysfunction (ED).

METHODSA total of 3130 Uigur cases of ED received in Xinjiang Bogda Hospital were divided into a control group (n=625) and a trial group (n=2505), the former treated with oral sildenafil alone, and the latter by the combination of the improved genital therapy and sildenafil, both for 3 months and followed up at 6 and 12 months after the treatment. The therapeutic effects were evaluated and compared using IIEF-5.

RESULTSThe IIEF-5 scores of the control group were 12.80 +/- 3.76 and 18.10 +/- 2.61 before and after the treatment, and 17.35 +/- 2.73 and 16.64 +/- 2.63 at 6 and 12 months, respectively, while those of the trial group were 12.73 +/- 3.52 and 19.06 +/- 4.07 before and af- ter the treatment, and 19.86 +/- 2.42 and 20.47 +/- 2.38 at 6 and 12 months, respectively, with statistically significant differences either between pre- and post-treatment (P < 0.05) or between the control and trial groups at 6 and 12 months (P < 0.05).

CONCLUSIONThe combination of the improved sex therapy and oral sildenafil is superior to sildenafil alone in the treatment of ED, and its efficacy is relatively stable at 12 months.
