●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

OBJECTIVERNA interference was applied to knockdown the Dhcr7 gene in mouse embryonic palatal shelves to facilitate understanding of the function of Dhcr7 gene variants in the fusion of palatal shelves.

METHODSThe pAdTrack-CMV-siDhcr7 was constructed using the specific siRNA sequence of Dhcr7 from C57BL/6J mouse. The pAdTrack-CMV- siDhcr7 of positive clones was reconstructed in vitro, and the recombinant adenovirus pAdEasy-1-siDhcr7 of kanamycin resistance was screened. The adenovirus vector DNA was then prepared for transfecting the embryonic palatal shelves. Thirty pairs of embryonic palatal shelves at 13.5 d gestational age were harvested and then randomly divided into the following three groups: normal control group (n = 10), which included palatal shelves inculture medium without cholesterol; blank adenovirus control group (n = 10), which included palatal shelves in culture medium without cholesterol and blank adenovirus; and experimental group (n = 10), which included palatal shelves in culture medium without cholesterol and adenovirus encoding Dhcr7 siRNA. At 48 h after in vitro cultivation, the mRNA and protein of the palatal shelves were obtained for scanning electron microscopy (SEM), reverse transcription polymerase chain reaction (RT-PCR), and Western blot analyses.

RESULTSSEM showed that the palatal shelves of the normal control and blank adenovirus control groups fused and formed continuous palates, whereas those of the experimental group was almost undeveloped but exhibited large gaps between the two palatal shelves. RT-PCR and Western blot analyses showed that the mRNA and protein of Dhcr7 in the experimental group decreased compared with those in the normal control group with a significant difference (P < 0.05).

CONCLUSIONResults indicate that Dhcr7 gene silencing affects the fusion of palatal shelves. Thus, Dhcr7 gene may serve a function in the normal development of palates.

Objective To investigate the clinical efficiency of repairing ankle and calf wounds by antegrade or retrograde perforating flap of posterior tibial artery. Methods 13 cases with skin defects of ankle and calf wounds were reviewd. The defects were repaired using antegrade or retrograde perforating flap of posterior tibial artery from January 2011 to February 2013, 8 males and 5 females; aged 19 to 65 years old. Wounds were located in the ankle and calf, area which the tibial artery support contu-sioned slightly;defects were associated with exposed bone or tendon, exposed blood vessels. Of the 13 cases, 5 cases have multiple ankle fracture with blood circulation disorders, internal and external fracture fixation were performed emergency with blood ves-sels and nerves exposed, at the same time emergency line wound repair by posterior tibial artery perforating flap. The other 8 cases have no blood vessels and nerves exposure, and accepted vacuum sealing drainage emergency external fixation and flap surgery. Seven cases accepted V-Y antegrade perforating flap of posterior tibial artery, 6 cases using retrograde tibial artery perforator flap. Whose defects were ranged from 1.5 cm×2.0 cm to 9.0 cm×5.0 cm. Antegrade or retrograde perforating flap of posterior tibial ar-tery with 1.5 cm×3.0 cm to 14.0 cm×7.0 cm was used to repair ankle or lower leg medial defect. Antegrade flap donor site sutured directly, but retrograde flap donor site take full thickness skin graft repair from abdomen. Results Circulations of the all 13 cases were stable, with wound healing well after 2 weeks. The patients were followed up for 6 months to 24 months, average of 13 months. All flap graft survived, pedicle no bloated andcat eardeformity. Flaps were soft, no bloated appearance;color was con-sistent with normal skin. Fracture line in the 5 patients was disappeared. Bone healing time was 3.0 to 4.0 months. At the direct su-ture skin donor sites, postoperative scar was small;skin graft donor sites had no obvious scar. Postoperative ankle dorsiflexion 10° to 25°, plantar flexion 15° to 45°. Patients were extremely satisfied with the results of repair. Conclusion Using antegrade or ret-rograde posterior tibial artery perforator flap without sacrificing the main vessel, it is a simple and effective method to repair the medial malleolus and calf wounds.

OBJECTIVETo investigate the application of relay flaps pedicled by perforator from digital artery for reconstruction of soft tissue defects at finger tip.

METHODSFrom Mar. 2012 to Jun. 2014, 9 cases with soft tissue defects at finger tip were reconstructed with relay flaps at one side of finger pedicled by perforator from digital artery. The flap size ranged from 1.3 cm x 1.6 cm to 1.6 cm x 2.2 cm. The defects at donor sites were covered by adjacent web perforator V-Y advanced flaps.

RESULTSAll the 18 flaps in 9 cases survived completely with primary healing both in recipient and donor sites. The patients were followed up for 5 months to 2 years ( average, 12 months) with good elasticity and cosmetic results. No pain happened in the treated finger. The 2-point discrimination distance was 7-8 mm in fingertip flaps, and 10-12 mm in web perforator flaps. Hand function was graded as excellent in 7 cases, good in 2 cases, based on ATM assessment. The affected fingers had normal temperature and cold-resistance during winter. The width and depth of web in the donor site were not affected.

CONCLUSIONSThe relay flaps pedicled by perforator from digital artery can be applied for reconstruction of soft tissue defects at finger tip. The procedure is easy with satisfactory results and reservation of main artery. No skin graft is necessary for closure of defects on donor sites.
