[Summary] From November 2013 to March 2014, 3D laparoscopic operations were carried out in 14 cases in the department of urology of our hospital .The operation went smoothly , without conversions to laparotomy .The operation time was 54-466 min, with an average of 180 min.The intraoperative blood loss was 5 -400 ml, with an average of 70 ml.No pressure sores or operation complications occurred.The medical staff participating in the operation generally felt a good 3D vision, without sense of vertigo.We deem that during urological operations which have different operation postures , it is very important to protect both laparoscopic system and operation area from pollution .Timely and properly wearing 3D glasses, application of one-eye-detection method for lens sharpness , and the switching between 2D and 3D modes can reduce and relieve visual fatigue .

Background Idiopathic macular epiretinal membrane (IMEM) shows a high incidence and affects visual function of patients.The primary management of IMEM is vitrectomy,but the study on prediction of visual acuity after operation by optical coherence tomography (OCT) is seldom.Objective This study was to evaluate the predicting ability of OCT for preoperative visual outcome for IMEM patients who received vitrectomy.Methods The clinical data of IMEM patients with vitrectomy from March 2009 to May 2013 were retrospectively analyzed in People's Hospital Peking University.Forty-nine eyes of 48 cases were divided into continuous group (19 eyes of 18 cases) and discontinuous group (31 eyes of 31 cases) based on whether the extraretinal layers were intact on OCT,including retinal pigment epithelium (RPE),inner and outer segment of photoreceptors (IS/OS) and external limiting membrane (ELM).Central foveal thickness (CFT) by high-resolution spectral-domain OCT and best corrected visual acuity (BCVA) (LogMAR) before surgery and 12 weeks after surgery were recorded and compared between the two groups,and the correlations of shift of CFT with the shift of LogMAR vision was analyzed by unitary linear regression to evaluate the value of OCT in predicting postoperative vision.Writen informed consent was obtained from each patient prior to any medical operation.Written informed consent was obtained from each patient before surgery.Results In 12 weeks after operation,reflective strips of RPE layer,IS/OS and ELM layer were intact in 18 eyes of the continuous group after vitrectomy.The number of eyes with discontinuous strip in RPE layer decreased to 1 eye after operation from 6 eyes before operation,and the number of eyes with IS/OS reflective strip discontinue decreased to 19 eyes after operation from 29 eyes before operation,and that with ELM layer discontinue decreased to 15 eyes after operation from before operation in the discontinuous group.The improvement of LogMAR BCVA was increased with the decline of CFT values with a negative correlation between them (R2 =0.298,B =0.001,P =0.000),and postoperative LogMAR visual acuity improved 1 line whenever CFT reduced by 100 μm.LogMAR BCVA was 0.4±0.19 before surgery and 0.36±0.21after surgery in the continuous group,showing a insignificant difference between them (t =0.876,P=0.393).In the discontinuous group,the postoperative IogMAR BCVA was significantly higher after operation (0.46±0.26) than 0.82 ±0.41 after operation (t =6.206,P =0.000).The increase value of LogMAR after vitrectomy was 0.3 in the discontinuous group,which was superior to 0.0 of the continuous group.Conclusions The continuity of extraretinal layers and CFT by OCT are closely associated with the improvement of vision after vitrectomy in the eyes with IMEM.Postoperative vision is better in IMEM eye with continuous retinal reflective strips before operation,and majority of IMEM eyes can improve vision after operation.Preoperative OCT seems to be an important diagnostic tool for the selection of patients who benefit or not from surgery to certain extent.

The technique of nipple-areola complex (NAC)-sparing mastectomy (NSM) facilitates the breast reconstruction due to preserving the skin and NAC of breast in the treatment of breast cancer. Key issues still remain controversial in NSM, in terms of the role of radiotherapy combined with NSM and sequence of radiotherapy and NSM, which arise from the consideration of the oncology safety. Some investigations addressed that post-NSM external beam irradiation and intra-operative radiotherapy (IORT) combined with NSM could reduce the local recurrence rate. Based on the appropriate patient selection and good quality of surgery, radiotherapy would be applied in different strategies of combination with NSM according to the risk of local recurrence of the cancer.
