AIM: To establish the technique of precision-cut fibrotic liver slice (PCLS) and grope the optimal cultural conditions for researching the liver xenobiotic metabolism in vitro and the drug interaction. METHODS: Complex factors (higher fat diet, alcohol and CCl 4) were used to make the animal model of liver fibrosis. Fibrotic liver slices were prepared and cultivation system was established. Lactate dehydrogenase (LDH) leakage, glutathione S-transferase (GST) activity and 3[4,5-Dimethythiazole-2-yl]-2,5- diphenyltetrazolium bromide (MTT) reduction were chosen as indexes to assess the viability of the slice in different thickness, medium pH and cultural time. RESULTS: Rats were in earlier hepatic fibrosis after administration for 3 weeks. When the thickness of slices was 300 ?m and medium pH was 7.0, the LDH leakage, GST activity and MTT reduction could maintain on a steady level in 6 h. CONCLUSION: A 300 ?m of thickness, 7.0 of medium pH and 6 h of cultural time are the optimal slicing and culturing conditions for fibrotic liver slice.

Development of primary angle closure glaucoma (PACG) is closely related to the changes of the position and morphology of the lens owing to a shallow anterior chamber,pupillary blockage and angle closure.Lens extraction can deepen the depth of the anterior chamber and resolve the pupillary blockage,and therefore increase the outflow of aqueous fluid.Furthermore,the combination of lens extraction with goniosynechialysis can reopen the closed anterior chamber angle and relieve peripheral anterior synechia of pupil,with a better clinical effectiveness for primary angle closure glaucoma.Recently,the studies related to lens extraction for primary angle closure glaucoma have madc great progression,especially its mechanism and efficacy,and of course some existing problems of lens extraction are concerned.In this review,the relationship between lens and primary angle closure glaucoma,the clinical effectiveness of lens extraction for primary angle closure glaucoma,the safety evaluation of lens extraction and goniosynechialysis were summarized.

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.

Objective To investigate the role of PAG in migraine Methods A transformed superior sinus stimulation migraine model was applied to observe Fos expression and co localization of 5 HT with Fos in PAG following the stimulation of dual matter adjacent to the superior sagittal sinus in rats Results 5 HT immunoreactive neurons, densely located in ventrolateral and ventromedial sectors, were found throughout the PAG Fos like immunoreactivity neurons were obviously increased in stimulated group than in unstimulated and control groups The double labelled neurons accounted for 15 0%?2 8% of 5 HT immunoreactive neurons and 24 0%?4 3% of Fos like immunoreactivity The double labelled population mainly distributed in ventrolateral sector Conclusions It suggests that neurons in PAG, especially in ventrolateral sector in caudal segment, might be excited in migraine model of rat The excited cells and 5 HTnic neurons might have a similar distribution pattern in PAG, with part of excited cells being 5 HTnic neurons Other types of excited neurons and the subtype of 5 HT receptor were not included in the experiment, and would be studied further as to getting a better understanding of the pathophysiology of migraine

[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 .

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.
