AIM: To observe the clinical effects of intravitreal injection of triamcinolone acetonide ( TA ) before vitrectomy for retinal detachment associated with choroidal detachment. · METHODS: Totally 23 cases ( 23 eyes ) of retinal detachment associated with choroidal detachment in our hospital were treated by intravitreal injection of TA 4-5d before 23-Gauge micro-invasive vitrectomy combined with silicone oil injection. All the cases were followed up between 6 to 9mo. The anatomic retinal reattachment, visual acuity, intraocular pressure and postoperative complications were observed and analyzed. ·RESULTS: After the surgery, the visual acuity of all patients were improved, with 9 eyes better than 0. 3 (39%), and 18 eyes better than 0. 05 (78%). The BCVA at 1wk, 1 and 3mo and last follow up were different compared with before operations (P<0. 05). The mean intraocular pressure was 4. 02±1. 47mmHg before injection, 13.69±4. 68mmHg before operation (P<0. 05), and17.72±5.87 mmHg after operation (P<0.05). The retina of all patients treated were reattached 2wk post-operatively. The retinal reattachment rate after the primary surgery and the secondary surgery was 87% and 100%, respectively. Post-operative complications included 7 eyes of transient high intraocular pressure, occurred during 12-14d after operations and returned to normal after less glucocorticoid eye drops and giving IOP lowering drugs. There were no intraocular hemorrhage, iatrogenic retinal breaks, infections, or lens injuries. · CONCLUSION: Intravitreal injection of TA before vitrectomy for retinal detachment associated with choroidal could improve the clinical effects, and decrease the difficulty of surgery while the injection itself is pretty safe.

Objective To evaluate the clinical applications and surgical methods of combined laparoscopic common bile duct (CBD) exploration with choledochoscopy. Methods From 2006 to 2009,clinical data of 42 patients with choledocholithiasis undergoing laparoscopic common bile duct exploration were retrospectively analyzed. We applied a step-by-step electric coagulating incision technique on the CBD,the step-by-step suturing technique, and the step-by-step clamping technique with alligator forceps, and soft tube irrigating technique with suctioning by selecting the proper exploration route, improving the common bile duct incision technique and calculus removing techniques. Results Procedures were successful in all the cases. There was no conversions to open surgery, no postoperative bleeding and no operative mortality. The mean operating time was 120 minutes (ranging, 90 to 150 minutes) with minimal intraoperative blood loss ( ranging, 20 to 40 ml). Ductal stone clearance was successful in 41 out of 42 patients ( 93% ). The largest number of the common bile duct stones was 16. With the diameter of stones larger than 15 mm in 18 cases in which the biggest was 30 mm. Bile leak developed in 1 patient, retained stones found in 3 patients,including intrahepatic cholelithiasis in one case. As a result, 38 out of 42 patients underwent common bile duct exploration. 35 patients were placed on T-tubes. Four patients underwent cystic duct exploration in which 3 had primary suture of the cystic duct and 1 had drainage. There was no infection and stenosis of biliary tract in the 42 followed-up cases. Conclusions Laparoscopic common bile duct exploration with stone extraction can be performed with high efficiency, minimal morbidity and without mortality. Improving the way of operation and selecting suitable exploration can result in better clinical outcomes.

ObjectiveTo investigate the role of platelet-derived growth factor(PDGF) and its receptor in the development of hypertrophic scar. MethodsThe expression of PDGF and its receptor were detected in biopsy specimens of 9 pieces of normal skin, 7 pieces of granulation tissue of burn wound and 34 pieces of hypertrophic scar by immunohistochemical staining using specific polyclonal antibodies.ResultsPDGF and its receptor markedly increased in granulation tissue and hypertrophic scars, reaching the peak in the hypertrophic scars within 6 months and then decreased after the peak, whereas PDGF and its receptor expressed weakly in only a few normal skin specimens, and the differences were significant(P<0.05).ConclusionsThe increasing expression of PDGF and its receptor may be related to the development of hypertrophic scar.
