砄bjective: To evaluate the effect on a transpalatal arch on reinforcing anchorage. Methods: 12 cases with ClassⅡ Division 1 malocclusion were selected and treated with a transpalatal arch for reinforcing anchorage. Results: ①The forward displacement of the first maxillary molar (6 Ptmo, 6 So, 6CR So and 6AP So) , the backward displacement(1 Ptmo and 1 So ) and the reduction of the axial inclination (1 NA and 1 SN) of the upper incisors were increased( P 0.05);③The forward displacement of the first maxillary molar was less than one third of the extraction space ( P

Objective: To study the effective initiating time of the maxillary protraction therapy for the children with skeletal classⅢ malocclusion. Methods: 20 cases with class Ⅲ malocclusion were divided into 2 groups: older group (9～ 12 years old) and younger group(5～8 years old), and treated with maxillary protraction. Before and after treatment cephalometric radiographs were taken and analyzed. Results: Good effects were found in both groups. The treatment in the younger patients showed the advantages of shorter treatment period, more skeletal changes, less dental changes and less side effects. Conclusion: Earlier maxillary protraction is more beneficial to the children with Angle Ⅲ malocclusion.

Objective To investigate the role of apoptosis and the regulating role of receptor interacting protein 1(RIP1) in acute pancreatitis .Methods Thirty C57 mice were divided into three groups :control group ,acute edematous pancreatitis (AEP) group and acute necrotizing pancreatitis (ANP) group .The AEP group was continuously injected by cerulein 50 μg/kg for 13 times ,the ANP group was continuously injected by cerulein 50μg/kg for 13 times and lipopolysaccharide 15 mg/kg once;the con‐trol group was injected by the same volume of normal saline for 7 times .The acinar cell apoptosis was observed by the terminal de‐oxynucleotidyl transferase‐mediated deoxyuridine triphosphate nick‐end labeling (TUNEL) assay .The RIP1 mRNA expression was measured by real time fluorescence PCR .The expression of RIP1 protein was detected by Western blotting .Results The mouse models of AEP and ANP were established successfully .Compared with the control group ,acinar cell apoptosis existed in both AEP and ANP model groups ,moreover compared with the AEP group ,apoptosis in the ANP group were decreased ,the differences were statistically significant(P<0 .05) .Compared with the control group ,the expression of RIP1 mRNA and protein in the AEP group was increased ,while which in the ANP group were decreased ,the differences were statistically significant(P<0 .05) .Conclusion RIP1 participate in the pathogenesis of acute pancreatitis ,which may associate with acinar cell apoptosis .

Objective In order to explore the relationship between the “Wits" appraisal and the ANB angle, and to see how accurately one can predict the “Wits”. Methods Given the ANB, lateral cephalometric radiographs were taken on 50 boys and 50 girls between the ages of 11～13. Results Each subject had no treatment either a Class Ⅰ or Class Ⅱ malocclusion, a good growth pattern. Group Ⅰ , 13 subjects of 100 had ANB≤1.5°, and negative “Wits” appraisal; group Ⅱ , 61 subjects had 5.8°＞ANB＞1.5°, and “Wits” appraisal either positive or negative; group Ⅲ , 26 subjects had ANB angle≥5.8°, and positive “Wits” appraisal. Statistically analysis showed that there was no sig nificant difference in sex (P＞0.05); there was significant correlation between the ANB and “Wits” values in the group Ⅱ and group Ⅲ (P ＜0. 05); there was statistical significance in regression analysis in the group Ⅰ and group Ⅱ (P ＜0. 05). We could predict the “Wits” with 21％ accuracy in group Ⅱ. Conclusion The results indicate that these figures are statistically significant but clinically irrelevant.

0.05). The cutaneous part occupied 2/3 of the entire upper lip height and the vermilion 1/3.The cutaneous part occupied more than 1/3 of the entire lower lip height.The chin occupied more than 60 percent of the entire mandibular height. Conclusion: The results of the study are consistent with the date of Farkas.

Objective To study prognosis and grading of somatosensory evoked potential(SEP)in long-term unconscious patients after severe traumatic brain injury(TBI).Methods Five prognostic factors including age,sex,injury mechanism,history of temporal craniotomy and SEP grading were selected and analyzed in 47 patients after severe TBI with a duration of unconsciousness longer than two weeks.The prognosis was judged by Glasgow Outcome Scale.Results Prognosis was closely associated with SEP grading(P=0.024).The accuracy of SEP in assessing the prognosis was 91.5%.About 95%-100% of patients with SEP at grade Ⅲ-Ⅲ ended up with severe disability,persistent vegetative state or death.However,43.75% of patients with SEP at grade Ⅰ had good prognoses.Conclusions The SEP grading can objectively and accurately evaluate patients' prognosis and demonstrate the brain function.

Objective The aim to assess the methodology and feasibility of ultrasound guided percutaneous thrombin injection(UGTI) for the treatment of Iarogenic Femoral Arterial Complexity Pseudoaneurysms(IFACP).Methods Thirty two iarogenic femoral arterial complexity pseudoaneurysms patients following femoral arerial puncture for arterial angiography were treated with UGTI.Twenty-three IFACP with 2 lobes,8 IFACP with 3 lobes,1 IFACP with 4 lobes.Under local anesthesia the lobe was pene trated by artery needle successively and thrombin jection was performed slowely into distal lobe with US guide precise localization.Dynamical observation was performed for the status of thrombogenesis and cavity plugging.US follow-up examination were performed after 24 h and 7 d.Results Reperfusion occurred in IFACP with 3 lobes after 24 h and UGTI failure.IFACPs with 4 lobes failure.Nothromboembolic,infectious,allergic complication soccurred.Conclusion UGTI is the first mothed for the treatment of IFACP.Precise localization and percutaneous can enhance the ratio of treatment of IFACPs and avoid the severe complications.

Objective To investigate the relationship between the level of mindfulness and the A-type behavior characteristics of the nursing college students.Methods 172 nursing college students were investigated by the scale of TABP and FFMQ.The results were analyzed.Results In the 172 nursing college students,there were 112 nursing college students belonging to type B behavior pattern,accounted for 65.1％,and 60 nursing college students belonging to type A behavior pattern,accounted for 34.9％.The correlation between the score of TABP and the observation items and describing items were positive statistically significant,and was negatively correlated with awareness items and non-judge items statistically.Conclusions The students with different behavior characteristics were different in their mindfulness level.In order to improve nursing college students' mindfulness level and their mental health,the educators should take intervention based on their behavior characteristics timely.

Objective:To study the feasibility of rapid tooth movement by periodontal ligament distraction osteogenesis. Method: Periodontal ligament distraction osteogenesis technology was applied on the experimental side; traditional orthodontic tooth movement technology on the control side in 8 dogs. The treatment was countinued for 14 days. Tooth movement and alveolar bone remodeling were studied by in vivo measuring,roentgenogram, histology and immunohistochemistry 2,3,6 and 10 weeks after treatment respectively. Results:2 weeks after application of treatment tooth movement(mm) with periodontal ligament distraction osteogenesis and that with traditional orthodontic method was 3.49?0.57 and 1.06?0.32 (P0.05) respectively. Active osteogenesis was obsered on the tension loaded side, BMP expression on the experimental tension-loaded side was stronger than that in the control side (P
