Objective:To discuss the influence of intensive lipid-lowering therapy by atorvastatin on blood lipid and serum von Wille-brand factor ( vWF) and thrombomodulin ( TM) levels of patients with unstable angina pectoris. Methods: Totally 88 cases of patients with unstable angina pectoris were selected and divided into the intensive group (n=44) and the routine group (n=44) at random. The patients in the two groups were given routine medical treatment, such as nitrates, bayaspirin,β-blocker, low molecular heparin and etc. The patients in the routine group were orally given atorvastatin 20mg, qd, while the patients in the intensive group were given atorvastatin 40mg, qd with the treatment course of 8 weeks. The changes in serum vWF and TM levels in the two groups before and after the medical treatment were observed, and the occurrence rates of cardiac ischemia related events and untoward effect during the medical treatment were compared as well. Results:After the 8-week medical treatment, the levels of TC, TG and LDL-C in the two groups were obviously declined and the levels of HDL-C were obviously increased than those before the treatment (P<0. 05 or P<0. 01), and the declining and increasing rates in the intensive group were much higher than those in the routine group (P<0. 05). The serum vWF and TM levels in the two groups were obviously declined than those before the treatment (P<0. 05 or P<0. 01), and the declining rates in the intensive group were much higher than those in the routine group (P<0. 05). The occurrence rates of cardiac ischemia related events in the inten-sive group during the medical treatment were much lower than those in the routine group (P<0. 05). Respectively 4 and 6 cases of unto-ward effect appeared in the routine group and the intensive group during the medial treatment with light symptom, and the difference showed no obvious statistical significance (P>0. 05). Conclusion:Atorvastatin intensive lipid-lowering has favorable curative effect and security in the treatment of unstable angina pectoris, which can reduce the occurrence rates of cardiac ischemia related events, and the mechanism is related to reducing blood lipid and serum vWF and TM levels and improving the function of vascular endothelial cells.

Perforator flaps became popular in past 30 years due to the minimum donor site morbidity and good aesthetically contour. Limitations are found in the use of traditional perforator flap, such as limited surface area, unsuitable for repairing super-long wounds, extensive wound and wounds accompanying with dead space, etc. Special form of perforator flap is derived from the perforator flap. It overcomes the shortcomings of traditional perforator flaps, such as less donor-site morbidity, thinner flap, better patient satisfaction and without severe complications in the recipient area. In addition it further improves the clinical curative effect and enhances the value and the applications of perforator flaps. In this article, the historical development and evolution of special form perforator flaps are reviewed, and the clinical applications of the special form perforator flap in recent years are summarised, for the purpose to promote the application and development of special form perforator flap in the reconstruction of complex soft tissue defects.

Objective To explore the method of sensory reconstruction after the operation of reversed island pedicled sural flap and evaluate its therapeutic effect of clinical application. Methods Thirteen clinical cases with traumatic soft tissue defects in heel had recepted the treatment of reversed island pedicled sural flap. All flaps were innervated by anastomosing the distal end of the sural nerve in the flaps and the recipient nerve (superficial peroneal nerve) in end to end or end to side. All patients were evaluated at 9-15 months on the postoperative follow-up parameters, including flap contour, flap stability, locomotor activity,touch sensation, pain sensation, static two-point discrimination, thermal sensibility, and the skin sensory recovery level in lateral dorsutn of foot. Results Thirteen cases flaps had good blood supply and primary healing. All cases were followed up 9-15 months, the rate of good sensory recovery was 53.85%. All pa tients had protective sensory in lateral dorsum of foot, the rate of good sensory recovery was 61.54%. Conclusion Anastomosing the proximal end of sural nerve and superficial peroneal nerve together will be good for the sensory recovery in flap and lateral foot in repairing soft tissue defects in heel with reversed island pedicled sural flap.

Objective To describe a technique to achieve primary donor-site closure, extend applications and minimize donor-site morbidity by applying the double skin paddle principle.Methods All 16 cases of the double skin paddle anterolateral thigh perforator flap reconstruction from May, 2008 to June, 2014 were reviewed.Defects locations included calf, dorsum pedis or planta pedis.A long anterolateral thigh perforator flap was marked out using standard points of reference.At least two separate cutaneous perforator vessles were identified on hand-held Doppler.Separating and dissecting flap at superficial layer of fascia lata was adopted in all cases.Then skin paddle was then divided between the two cutaneous perforators to give two separate paddles with a common vascular supply which was the descending branch of the lateral circumflex femoral artery.The skin paddles could be used to cover complex skin defects, whilst still allowing for primary donor-site closure.Results Fifteen patients were successfully treated with the double skin paddle anterolateral thigh perforator flap with no major complications.One case was suffered with partial skin flap necrosis.The type A dumbbell-like flaps was used to cover defects involving two different units of the foot.The type B pattern were stacked side by side on a flap inset, effectively doubling the width of the flap, to resurface a large defect of a single unit of the calf.The type C pattern was used to repair adjacent skin defects.In all cases, the donor site was closed directly.All patients were satisfied with their outcomes.Conclusion The double skin paddle anterolateral thigh perforator flap is an excellent method of resurfacing large defects of the extremity involving multiple subunits with improved morbidity and cosmesis of the donor site.

OBJECTIVETo explore the feasibility and the effect of free chimeric perforator flap with deep inferior epigastric artery for the soft tissue defect on the lower extremity with deep dead space.
METHODSFrom Mar. 2010 to Aug. 2011, 8 patients with soft tissue defects on the lower extremities combined with dead space, bone or joint exposure were reconstructed with free hinged perforator flaps with deep inferior epigastric artery. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The defects on the donor sites were closed directly.
RESULTSAll the flaps survived with primary healing. Good color and texture was achieved. The patients were followed up for 12-24 months, with an average of 16 months. 2 over-thick flaps were treated by flap-thinning surgery. Only linear scar was left on the donor site on abdomen with no malfunction.
CONCLUSIONSThe free chimeric perforator flap with deep inferior epigastric artery can simultaneously construct the dead space and superficial defect with only anastomosis of one set of vascular pedicle. It is an ideal method with good results on recipientsites and less morbidity on donor sites.
