?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

Purpose To evaluate the clinical and pathological features of extramammary Paget’ s disease ( EMPD) and to investigate the related prognostic factors. Methods The clinical and pathological data of 30 patients with EMPD were reviewed retrospectively. The HE slides in the file were rechecked. Immunohistochemical stains were performed on archival paraffin-embedded sections with En-Vision method in 20 cases. Follow-up data were recorded. The relationship between the clinicopathological parameters and prognosis was statistically analyzed. Results Among the 30 patients, there were 26 males and 4 females, aged from 53 to 88 years with median age 70. Macroscopically, typical presentations of EMPD were eczematoid lesions. Microscopically, Paget’s cells were distributed sin-gly or in groups ( as glandular or nests patterns) within the epidermis. Immunohistochemical stains showed that Paget’ s cells were pos-itive for CK7, and negative for CK5/6 and p63. Follow-up data were available in 23 cases, 8 cases recurred resection, among them, 6 patients had positive resected margin and 4 died. The recurrent rate and mortality between the groups of dermal invasion and no der-mal invasion (P<0. 01 and P<0. 05), the groups of lymphatic metastasis and no lymphatic metastasis (P<0. 01), and the groups of positive and negative resected margin (P<0. 01 and P<0. 05) were statistically different. There were no statistically different with age and extent of lesion (P>0. 05). Conclusions CK7 is a sensitive and specific marker of Paget’s cells. Dermal invasion, lymphatic metastasis and positive resected margin are poor prognostic factors in EMPD.

Objective To explore the effect of using pedicle skin flaps for treatment of skin and soft tissue defects.Methods From January 2004 to September 2010,87 patients with skin and soft tissue injury which had been treated by using pedicle skin flaps without vessel anastomosis were retrospectively analyzed,including 61 males and 26 females with an average age of 40 years (range,14-61).The pedicle skin flaps selected were known vessel skin flaps or unknown vessel random skin flaps.The reconstruction treatment increased multiple selections of skin flaps for patients.Skin and soft tissue defects were located at the hand in 21 cases,at the lower extremities in 66.The kinds of skin flaps included adjacent transposition flaps in 50 cases,distal skin flaps in 37.The areas of the skin flaps were 2.0 cm×1.5 cm-18 cm×12 cm.Donor sites were as follows:lower leg in 61 cases,abdomen in 18,and hand in 8.Results Three patients appeared skin flaps hematoma after operation,which were removed immediately with no effect on flaps survival.Pedicle skin flap was compressed due to unstable fixation in 1 case,which made distal flap tissue necrosis approximately 2 cm in width.After dressing change for 6 weeks,the flaps got survival.Thirty seven patients underwent the second stage operation for breaking the perdicle 3 weeks after the first operation.All 87 patients were obtained follow-up for an average of 13 months (range,3-60).The total of 90.80％ patients treated with pedicle skin flaps were satisfied with the results.Conclusion Pedicle skin flap surgery can be performed more easily with less limitations of surgical designs.The survival rate of the flap is high,and the treatment of pedicle skin flaps could be well applied for soft tissue defects.

?AlM:To evaluate and observe the efficacy of silicon oil ( SO ) , perfluoropropane ( C3 F8 ) and balanced salt solution ( BSS ) that can be used as tamponade during vitrectomy to treat proliferative diabetic retinopathy ( PDR) complicated with vitreous hemorrhage ( VH) .
?METHODS: Studied retrospectively on 74 eyes of 60 patients who underwent vitrectomy surgery with diabetic vitreous hemorrhage in our hospital during June 2008 and June 2014. Based on repeated prior examines on fundus details and the vitrectomy tamponades were chosen. All the patients had been followed up at least 3mo. Depending on different tamponades, the paitents were nonrandomized in three groups and contrasted as visual acuity, intraocular pressure ( lOP ) and complications respectively.
?RESULTS: There was statistically significant difference among these three groups in preoperative eyesight ( P<0. 05 ). Moreover, the preoperative eyesight was statistically different between SO and BSS (P<0. 05), and difference for the rest being not remarkable(P>0. 05). The difference being statistically difference in the postoperative vision among these three groups ( P <0. 05). The further analysis showed that the paired-comparisons were statistically significant difference between SO and BSS ( P<0. 05 ), while the rest two groups of comparison were non-respectively(P>0. 05). The preoperative visual function was in contrast to the postoperative (P<0. 05). The lOP before surgery was not statistically significant difference(P>0. 05). However,the difference among three groups being statistically in the postoperative vision(P<0. 05), in addition,the difference existed in each group through pairwise comparison ( P<0. 05) . The occurence rate of complications after surgery in this survey was 47%, the SO group was 50%, the C3 F8 was 56%, the BSS group was 44%.
? CONCLUSlON: Vitrectomy is a safe and effective treatment that can help patients who have diabetic vitreous hemorrhage obtain better visual improvement. Because of the physicochemical properties and different conditions, there still has complications after surgery.
