Orthopedic Journal of China 2006;0(06):-
[Objective]To establish a scoring standard of operative risk assessment for the orthopaedic surgery and evaluate the reliability of it.[Method]Anivariable analysis was performed for the preoperative and intraoperative clinical data of 768 patients undergoing orthopaedic surgery from Jan.2001 to Dec.2008,the risk factors associated with orthopaedic surgery were selected.Then multivariable analysis with logistic regression was performed for the selected risk factors.The scoring standard was made through these data.Reliability of the standard was evaluated by predicting of 160 patients in spinal surgery from 2006 to 2008,comparing with the real situation of each operation.[Result]Anivariable analysis showed age,heart function,blood pressure,electrocardiogram,sternum,liver function,renal function,albumin,blood sugar,number of operative variables within four weeks,magnitude,blood loss preoperation,timing of operation were risk factors.[Conclusion]The ORAOS could appropriately predict the occurrence of patients' postoperative complication before operation.

International Eye Science 2015;(2):273-275
To discuss long-term changes of refractive status in children after congenital cataract intraocular lens ( lOL) implantation and analyze its related influence factors.METHODS: Seventy cases ( 110 eyes ) with congenital cataract from January 2013 to January 2014 in our hospital were selected, according to the age of patients, they were divided into group A (<2 years old), group B (2~6 years old) , group C ( 7 ~ 12 years old ) . They were all given cataract extraction combined with lOL implantation in congenital cataract. Corneal curvature, axial length, refractive status of three groups after operation were compared, the influence factors ocular axis changes were analyzed. RESULTS: There were no statistically significant differences in corneal curvature of groups A, B, and C after operation ( P>0. 05 );The differences had statistical significances of the corneal curvature of group A after surgery and 3mo after operation (P<0. 05), there were no significant differences of the corneal curvature of group B, group C after surgery and 3mo after operation (P>0. 05);the corneal curvature 3mo after operation of group A was significantly higher than that of groups B and C (P<0. 05), there were no significant differences in the corneal curvature between group B, and group C after 3mo ( P>0. 05 ); There were no statistical significances on axial length after operation in groups A, B, and C (P>0. 05);Ocular axial length difference of group A 3mo after surgery was significantly higher than that of groups B and C ( P < 0. 05 ), ocular axial length had no statistical difference of group B, group c 3mo after surgery ( P>0. 05). Refractive status of three groups after operation showed myopia moving trend, refractive change rate and refractive diopter of group A after operation was significantly higher than that of group B, group C, the difference was statistically significant (P<0. 05). CONCLUSlON: After congenital cataract extraction combined with lOL implantation, patients present myopia refractive state trend. Performance of children below 2 years old is significant. The main factor of myopia is axial growth.

Chinese Journal of Medical Library and Information Science 2015;(1):50-54,60
Objective To mine the relation between leukemia and genes using Weka. Methods The papers on leuke-mia and genes were retrieved from PubMed, their subject headings and subheadings were extracted using BICOMB to generate co-occurrence matrix and term-paper matrix. The research hotspots were found by cluster analysis of the data on co-occurrence matrix using Weka and Cobweb. The literature was verified. Results The 42 high fre-quency words were clustered into 7 classes by Weka. No high frequency words of leukemia or genes were found in classes 1, 2, 4 and 5, indicating that their clustering efficiency was poor. The clustering efficiency of the other 3 classes was good. Conclusion Cluster analysis showed that leukemia is related with myc gene, ab1 gene, p53 gene, virus gene, immunoglobulin gene and mdm gene.
