Objective To establish mathematical model for the differential diagnosis of endoscopic gastric ulcerative lesions with the help of image processing software and statistical analysis method. Methods The microscopic images of 25 gastric ulcers and 25 gastric peptic cancers were collected from January 2013 to December 2013.Then the Photoshop CS4 software was used for image processing and representative measurements gathering(area,perimeter,roundness,height,width,gray scale,involving the density,color,lightness,pixels).Then the principal component analysis,the scatter plot and cluster analysis were performed by SPSS 16.0.Results According to the results of principal component analysis, Z1 showed a strong positive correlation with area,perimeter,height,width,cumulative density,pixel,which represented the shape statistics of ulcer.And Z2 showed a strong positive correlation with gray scale,color, lightness,which represented the color statistics of ulcer.On the Scatter plot,gastric peptic cancer images showed a stronger positive correlation with the principal component Z1 and Z2 .Clustering analysis results showed that for the majority of patients,there was a pattern in its incidence.In the gastric ulcer diagnostic models,the effective information should include area≤10 000;perimeter≤250;height≤90;width≤60;gray scale≥90;cumulative density≤190 000;color≥110;and lightness≥110(unit:pixel).In the gastric ulcera-tive cancers,the effective information should include area≥38 000,perimeter≥690,height≥300,width ≥ 426,gray scale ≤ 100,cumulative density ≥ 14 000 000,color ≤ 125,and lightness ≤ 130 (unit:pixel). Conclusion Among the endoscopic image data,area,perimeter,roundness,height,width,gray scale, cumulative density,color,brightness,pixels are important indices,which can contribute to the differential diagnosis of gastric ulcerative lesions.The established mathematical model based on the ten indices can be applied to predict and diagnose gastric ulcerative lesions.

Objective:To evaluate the bone alteration subject to remodeling and analyze the esthetic result following immediate implant placement of incisors.Methods:In this study,20 patients (1 3 women,7 men)were involved,who needed implants for incisors of maxilla.The patients received 23 im-mediate implants totally.On the day of surgery and 6 months after the implants were placed,Cone beam CT (CBCT)was taken.The thickness of the alveolar ridge and the vertical change of marginal bone levels onthe mesial and distal aspects of theimplants were measured using the computer software (Planme-caRomexis Viewer 3.6.0.R).The evaluation of esthetic result by labial convexity score (LCS)and pa-pilla index score (PIS)were analyzed pre-operation and one year after the final crown was delivered.The statistics with paired-t test for the measurement data and Willcoxon test for rating data were done by SPSS 20.0.Results:The survival rate in the two-year follow-up was 1 00%.The measuring point 1 (MP1 ), MP2,MP3 and MP4 (0,2,4,6 mm apical to the implant platform,respectively)got significant altera-tions after 6 months of the follow-up.These differences were statistically significant (P<0.05 ).The major alteration happened at MP1 and MP4,which got (-0.89 ±2.06)mm and (-0.75 ±1 .28)mm reduction of the alveolar,respectively.The marginal alveolar ridge resorption was (-0.42 ±1 .24)mm and(-0.91 ±1 .96)mm for Ankylos System and Replace System,respectively,and the difference was not statistical significant .The esthetic results were quite acceptable.Before treatment,1 8 incisors rated 3 for LCS,and 2 incisors rated 4 for LCS;after final restoration,only 5 incisors rated 3 for LCS,and 1 4 incisors rated 2 for LCS.Before treatment,1 5 incisors rated 3 for PIS;after final restoration,1 3 incisors rated 3 for PIS.There was no statistically significant difference for the PIS pre-operation and 1 year after final restoration,while there was statistically significant negative change for LCS.Conclusion:Even fol-lowing the proper surgical technique,the alveolar ridge wall still can’t be maintained after immediate im-plant placed in fresh socket of incisors.The inter-dental papilla could be well maintained,while due to the remodeling of labial bone,labial convexity will inevitably collapse.Therefore immediate implant still has esthetic risk.
