AlM:To investigate the influence of phacoemulsification with different incision on tear film.
METHODS:Tear film was monitored in 152 patients (169 eyes) after phacoemulsification. Patients were divided into two groups according to the type of incision:group A (76 patients, 83 eyes) with a 3. 2mm corneoscleral limbus incision phacoemulsification and group B (76 patients, 86 eyes ) with a sclemtic tunnel incision. Tear break-up time ( BUT ) , cornea fluorescein staining ( CFS ) , lid-parallel conjunctival folds ( LlPCOF) and lid-wiper epitheliopathy ( LWE ) were observed at 3d preoperatively and 1wk, 1, 3 and 6mo postoperatively. The results were analyzed using a Chi-square test and t-test with SPSS 17. 0.
RESULTS:BUT: The BUT of two groups was obviously shorter at 1wk, 1mo postoperatively, the differences were statistically significant (P<0. 05), however, there were no statistically significant at 3, 6mo(P>0. 05). CFS score:There was a large increase in CFS at 1wk, 1mo postoperatively, the differences were statistically significant between the two groups(P<0. 05), however, there were no statistically significant at 3, 6mo (P>0. 05). LlPCOF:There was a large increase in LlPCOF at 1wk, 1 and 3mo postoperatively, the differences were statistically significant between the two groups (P<0. 05), however, there were no statistically significant at 6mo (P>0. 05). LWE: There was a large increase in tear osmolarity at 1wk, 1mo postoperatively. The differences were statistically significant between the two groups (P<0. 05), however, there were no statistically significant differences between the two groups at 3, 6mo (P>0. 05).
CONCLUSlON:The stability of tear film in patients with scleral tunnel incision is much better than in patients with 3. 2mm corneoscleral limbus incision phacoemulsification. There is no significant difference between the two groups during later postoperative periods.

OBJECTIVETo explore the surgical management and its results of intercondylar fractures of the humerus through approach of osteotomy of olecranon (AOO) with dual steel plate.
METHODSFrom June 2001 to March 2007, 38 patients of intercondylar fractures of humerus were treated surgically through AOO, and the fracture was reduced and fixed with dual steel plate. There were 24 males and 14 females with a mean age of 37 years (range 19 to 48 years). All cases were closed fractures. The fractures were classified according AO included 12 cases of C1, 20 cases of C2 and 6 cases of C3. The time from injured to operation was 6 hours to 14 days (means 7 days).
RESULTSThese 38 patients were followed up from 5 months to 2 years (average 12 months). The wound healing of one patient was below the mark. After the treatment of change dressings, the wound healed. Of these 38 patients, no loosening or breakage of internal fixation occurred. All the osteotomies healed in 15 weeks averagely (range 12 to 22 weeks). According to Cassebaum scoring system, the results were excellent in 15 cases, good in 17 cases, fair in 5 cases and poor in 1 case.
CONCLUSIONThe technique of dual steel plate for the treatment intercondylar fractures of the humerus through approach of osteotomy of olecranon (AOO) offers many advantages, such as sufficient exposure easy, stable fixation and earlier exercise. Functional exercise in the early period is the crucial factor of enhancing the therapeutic effect.

In this paper, we propose that, the need of the costly re-initialization procedure can be completely eliminated by using the variation formulation, thus increasing the speed of computing operations. The edge detecting function in the geodesic active contour model is improved by incorporating a prior knowledge. The accuracy of the segmentation algorithm can be enhanced by using the minimal variance. Experimental results show that the proposed algorithm can segment the prostate ultrasound images effectively and avoid the problem of contour leakage.

OBJECTIVETo investigate the effects of the reconstruction of the mentum with cervical tissue flaps in the surgical management of postburn cervical scar contracture.
METHODSThirteen postburn patients with severe cervical scar contracture and mental deformity were enrolled in the study. The platysma flap (3 cases), scar tissue flap (6 cases) and cervical deep fascia tissue flap (3 cases), with the pedicle containing the facial and the superior thyroidal artery, were turned upwards to replenish mental soft tissue, and to form new mentum and sulcus mentolabialis. The cervical scars were repaired with expanded flap (11 cases), free flap (1 case) or trapezius muscular flap.
RESULTSThe post-operative cervical configuration was found to be good, and the tissue flaps for mental reconstruction healed satisfactorily. Ten patients were followed-up for 6 to 24 months. All flaps were successful and achieved good results, except that scar formation was found in the cervical linear incision in 4 patients.
CONCLUSIONTransfer of the platysma flaps, scar tissue flaps, or deep cervical fascial flaps for the reconstruction of cervical scar were simple and effective. The use of cervical scar tissue flaps could not only loose the constructed scar, but also beneficial in rectifying the configuration of the chin.
