Objective To explore the surgical treatment of posttraumatic epilepsy in functional cerebral area Methods After preoperative evaluation,nineteen patients with intractable posttraumatic epilepsy of functional cerebral area underwent multiple subpial transaction under the electrocorticogram monitoring during the operation, combining with anterior corpus callosotomy, anterior temporal lobectomy and selective amygdalo-hippocampectomy. Results The follow-up results showed seizures of these patients improved considerably. According to Engel' s grading,among 19 cases,10 cases were grade Ⅰ ,7 cases were grade Ⅱ ,2 cases were grade Ⅲ ,and no cases were grade Ⅳ. Conclusions The satisfactory clinical outcome of the surgical treatment of intractable posttraumatic epilepsy in functional cerebral area could be obtained with the help of careful preoperative evaluation and multiple subpial transaction under the electrocorticogram monitoring.

AIM:To investigate the expression of transmembrane protein 16A(TMEM16A) in Fischer rat thy-roid follicular epithelial ( FRT) cells and its electrophysiologic properties .METHODS: The eukaryotic expression vector of pUB6/V5-TMEM16A was constructed and transfected into FRT cells by liposome-mediated transfection .In order to ob-tain the high efficiency of gene transfection and expression , the quantity and ratio of lipid/DNA complexes were optimized . The FRT cells stably expressing TMEM16A were gained by the selection with blasticidin and confirmed by the techniques of RT-PCR and immunofluorescence .The expression and location of TMEM 16A in the FRT cells were observed under an in-verted fluorescence microscope .TMEM16A protein was associated with calcium-dependent chloride current , as measured with halide-sensitive fluorescent protein and patch-clamp technique .RESULTS: The results of double digestion and se-quencing indicated that TMEM16A was cloned into pUB6/V5.The results of RT-PCR and immunofluorescence confirmed that TMEM16A was expressed in the FRT cells after transfection with TMEM16A.The classical calcium-activated chloride channel currents were recorded in the FRT cells stably expressing TMEM 16A by the technique of patch-clamp and halide-sensitive fluorescent protein YFP-H148Q/I152L.CONCLUSION:The protein expression of TMEM16A in the FRT cells was observed.TMEM16A is the molecular identity of calcium-activated chloride channels .

Objective:To evaluate the long-term efficacy of laparoscopic-assisted natural orifice specimen extraction surgery (NOSES) colectomy using Cai tube for treating left-sided colorectal cancer.Methods:This was a randomized controlled trial. Inclusion criteria were as follows: preoperative pathological diagnosis of left-sided colorectal adenocarcinoma (rectal, sigmoid colon, descending colon, or left transverse colon cancer with the caudad margin ≥8 cm from the anal margin); preoperative abdominal and pelvic computed tomography (or magnetic resonance imaging) showing maximum tumor diameter <4.5 cm; and BMI <30 kg/m 2. Patients with synchronous multiple primary cancers or recurrent cancers, a history of neoadjuvant chemoradiotherapy, preoperative evidence of significant local infiltration, distant metastasis, or complications such as intestinal obstruction and intestinal perforation, or who were not otherwise considered suitable for laparoscopic surgery were excluded. A random number table was used to randomize sequential patients to NOSES surgery using Cai tube (non-assisted incision anal sleeve: patent number ZL201410168748.2) (NOSES group) or traditional laparoscopic-assisted surgery (CLS group). Relevant clinical data of the two groups of patients were analyzed, the main outcomes being disease-free survival, overall survival, overall recurrence rate, and local recurrence rate 5 years after surgery. Results:Patients in both study groups completed the surgery successfully with no requirement for additional surgery. After mean 70 (7–83) months postoperative follow-up, the 5-year overall postoperative survival in the NOSES and CLS groups was 90.0% and 83.3%, respectively ( P=0.455); disease free survival was 90.0% and 83.3%, respectively ( P=0.455); overall recurrence rate 6.6% and 10.0%, respectively ( P=0.625); and local recurrence rate both were 3.3% ( P=0.990), respectively. None of these differences was statistically significant. Conclusions:NOSES and CLS have similar long-term efficacy, and NOSES deserves to be used in clinical practice.
