Objective To investigate changes in craniomaxillofacial soft and hard tissues following orthodontic treatment by MBT edgewise technique with fix appliance in patients with Angle classⅡdivisionⅠmalocclusion. Methods Fifty patients with Angle classⅡdivisionⅠmalocclusion were selected in this study. All patients were treated with MBT edgewise technique. Cephalometrics tracings were performed before treatment and after treatment. Cephalometrics measurements were statistically analysed by t-test. Results After the orthodontic treatment, the main changes were the reduction of maxillary and mandibular prominence and the increasement of the Pg′B′-FH and Pog-Pog′and upper-lower prominence as well. The appearance of uncovered teeth by their lips was obviously improved. The changes of soft issue profile are the increment of nasolabial angle and the changes among UL-U1, LL-L1 and the E-line. Conclusion Patients with Angle classⅡdivisionⅠmalocclusion have normal overjet and overbite, and also have a better appearance of soft tissue after the extraction treatment.

Objective To review and summerize effectiveness and method of the Boston's balloon dilation in cardiac achalasia. Methods The intensified guide wire was inserted into stomach through mouth cavity under TV controll. The Boston's balloon was inserted to the cardiac stricture through the guide wire and dilatated with 15% contrast medium with to a maximum diameter for five minutes and then the balloon was dilatated again for 3~5 minutes, all together for 3~4 times. The severe stricture must be pre dilatated with 20~25mm diameter balloon. Results The balloon insertion was technically successful in all 26 patients. The once succese of ballon dilation was achieved in 24 patients and twice in other 2. Follow up time was from 2 weeks to 31 months(mean 10.6 months). Recurrent stenosis had not occurred in all patients. Remission rate of dysphagia was 100%. Esophageal reflux occurred in 3 patients. Conclusions The Boston's balloon dilatation is simple and effective for treatment of cardiac achalasia. The method sometimes may replace surgical procedure.

Objectives: To identify the peptide sequence of a epitope and study its three dimensional structure on molecule of cyclophilin A. Methods: Using anti oyelophilin A (CyPA) monoclonal antibody (McAb D4) as the capture antibody, the library displayed random heptapeptides was screened by biopanning. The phage clones with high affinity for McAb D4 were chosen and their inserts were sequenced and then the antibody binding site was searched for on three dimensional structure of CyPA with RasMol software. Results:After 3 rounds of biopanning, 7 phage clones with high affinity for McAb D4 were sequenced and 3 different species were obtained, five of seven clones shared a predominant consensus sequence, WSLQSFL. The amino acid sequences of the inserts were compared with that of human CyPA.No homologous sequence was found in the primary structure of CyPA. With the data from PDB database and RasMol software, we found that W121,S99,L98,Q111,S110,F112 and L122 constructed a hydrophobic pocket which may be the epitope for McAb D4. Conclusions: W121,S99,L98,Q111,S110,F112 and L122 may form a conformational epitope of cyclophilin A.
