Objective To study the technique of using the postauricular revolving door island flap in one-stage reconstruction of concha defect and its efficacy.Methods Fifteen cases of concha de fect were repaired by the postauricular revolving door island flap in one stage reconstruction from 2000-2010.The maximum size of defect was 2.7 cm× 3.0 cm,and the minimum was 1.0 cm×1.3 cm.Results All the island flaps were survived postoperatively,and satisfactory in auricular appearances of all patients by 6 months to 5 years follow-up.Conclusions The revolving door island flaps with abundant blood supply are transferred to reach the auricular defect,which match normal auricular tissue in contour,color,and texture. This flap on the retroauricular area is relatively concealed,and it therefore can be one of the best procedures for repair of the auricular defects,especially concha.

Complex regional pain syndrome (CRPS) is a neuropathic pain disorder, characterized by persistent and severe pain after trauma or surgery. Diagnosis is mainly based on clinical signs and treatment is based on a multidisciplinary approaches, including non-pharmacological approaches and occupational therapy，pharmacotherapy and invasive therapeutics. This article reviewed the current advice of diagnosis and treatment of CRPS.

Objective To investigate the role of Epstein-Barr virus(EBV) infection on the abnormal activation of peripheral B-iymphocytes of systemic lupus erythematosus (SLE) patients,and the relationship between EBV infection and the abnormal activation of B-lymphocytes and SLE activity is explored. Methods BamH I-W genome in EBV DNA of 52 SLE patients and 23 controls were examined by PCR-Southern blotting. The level of ANA and EBV VCA-IgM in sera was measured by ELISA. The expression of CD19+ and expression rate of CD19+ and CD23+/CD19+ in EBV-positive SLE patients was higher than that of EBV-negative patients. Meanwhile,the fluorescence signal of CD23 in B cell of EBV-positive SLE patients was stronger than that of EBV-negative ones. Conclusion EBV infection may be related to abnormal activation of B-lymphocytes.EBV may infect and activate B-lymphocytes by up regulating the expression of CD23 of B-lymphocytes. The abnormal activation of B-lymphoeytes is associated with SLE activity.

An ideal assessment is an essential aspectfor patients with rectal cancer in personal treatment management and prognosis prediction.Magnetic resonance imaging (MRI) plays a central role in this process.High-resolution MRI can be used to accurately measure the depth of extramural rectal cancer spread.Therefore,high-resolution MRI can define the tumor category of rectal cancer in accordance with American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC).MRI can detect the extramural venous invasion that has been demonstrated as an independently predicting factor for prognosis and survival of patients.In addition,MRI defines the tumor and relevant anatomy,providing the most detail on treatment choice.
