Objective To explore clinic effect and advantages of the free arm lateral neurocutaneous flap in repairing cutaneous defects of opisthenar.Methods Between July,2012 and December,2013,12 patients with skin and soft tissue defects in opisthenar caused by trauma factor,accident,machine injury,hot crush injury etc were treated with free arm lateral neurocutaneous flap at our institution.Vessels both in recipient and donor site were detect-ed by color Doppler ultrasound preoperatively.Relative cutaneous nervers were reserved in the flap during selective operation.The flap size resected range from 6 cm × 4 cm to 10 cm × 6 cm.The posterior cutaneous nerve of the forearm were included in the flap to restore sensory sesation after transection.The wound in the donor site was closed in in-tradermal suture primarily.Postoperative algesia,touch,temperature sensation,Weber test of flap were tested and reco-rded.The critia of follow-up in this study were donor site morbidity,abnormal sensations,functional outcomes and sat-isfaction.Results The success rate was 100 percent in the series cases.The average length of follow up was 35 months (range,24 to 41 months).The wound in recipient area healed primarily and flaps showed no pigmentation but fine overall appearance,texture,and elasticity.The functional recovery of protective sensation was S3+ in 4 cases,S3 in 6,S2 in 2.Patients with liner scar in donor site were higly satisfied with the flaps for the sake of no significant joint functional outcomes.In terms of sensory sesation,the excellent and good rate of flap reached to 83 percent.Conclusion The free arm lateral flap represented a constant vascular anatomy,rich blood supply.Easy dissection,pliable texture,skin colour close to dorsum of hand and the possibility to be innervated through the posterior cutaneous nerve of the arm acceptable donor side morbidity provide a good option for the reconstruction of cutaneous defects of opisthena.

Nipah virus (NiV) is a highly contagious zoonotic pathogen, responsible for a relatively high mortality in human and posing a serious threat to human health. There are currently no licensed vaccines or antiviral drugs. Preclinical studies on NiV vaccines with different strategies are mainly based on NiV glycoprotein (G) and/or fusion protein (F). Internationally, three NiV vaccine candidates are currently in the Phase I clinical stage. The risk of Nipah virus transmitted to China is relatively high. In order to cope with potential future epidemics, China should develop NiV prevention and control strategies, and accelerate Nipah virus-related technology reserves and vaccine development. This article introduces NiV from the aspects of microbiology, epidemiology, clinical characteristics, and vaccine research, and puts forward prevention and control suggestions in light of the risk of NiV transmission to China and China′s national conditions, hoping to provide reference for NiV vaccine research and development.
