ObjectiveTo compare the exposure, identification of parathyroid and postoperative complications between total thyroidectomy (TT) and subtotal/near total thyroidectomy (S/NT) for bilateral multiple thyroid nodules. MethodsA total of 278 cases were performed TT and S/NT randomly from Dec. 2006 to Dec.2009. The histology, identification of parathyroid and recurrent laryngeal nerves (RLN), and incidence of complications were compared between the 2 surgical procedures. The data were processed with t test or x2 test.Results227 cases were estimated to be benign preoperatively, among whom 28 cases ( 12.3% ) were diagnosed as focal cancer by postoperative pathology. The identification rate of parathyroid was 96.5% in TT group and 60.4% in S/NT group (P<0.05). The mean postoperative serum calcium level was 2.057 +0.016 mmol/L in TT group and 2. 15 + 0.019 mmol/L in S/NT group (P < 0.05 ). The incidence rate of transient hypoparathyroidism (HPT) was 16.9% in TT group and 5.7% in S/NT group (P<0.05). There was no statistical difference between the 2 groups in terms of the incidence rate of permanent HPT and transient recurrent laryngeal nerves (RLN) palsy ( P > 0.05 ). The incidence rate of permanent HPT was higher in reoperation cases ( 11.1% ) than in primary surgery cases (0.0%) in TT group ( P <0.05 ). ConclusionBased on the accurate technique under microscope field, TT is a safe surgical procedure for primary surgery with bilateral multiple thyroid nodules.

ObjectiveTo evaluate the nephroprotective effects of transplanting metanephric mesenchymal cells (MMCs) into the renal subcaspsule of rats with acute tubular necrosis (ATN) induced by gentamicin. MethodsMMCs were expanded in culture and immunocytochemistry was used to characterize the cells. After gentamicin-induced ATN, fluorescence-labeled cells were transplanted and traced in kidney tissues by fluorescence microscopy. Serum creatinine (Scr) and N-acetyl-b-D-glucosaminidase (NAG) were tested. Kidney pathology was studied by hematoxylin-eosin staining. Apoptosis was examined by the TUNEL assay. Ki-67 and Bcl-2 expression was examined by immunohistochemistry. ResultsMMCs were expanded in culture and the phenotype of the cells was vimentin-positive and keratin-negative. Compared with other ATN groups, in the MMCs-treated group, Scr and NAG clearly decreased[14d Scr: (101.38±20.46) μmol/L vs (248.78±23.15), (252.98±33.52), (229.08±18.18) μmol/L;NAG: (14.83±7.74) U/L vs (33.33±14.88), (29.62±10.54), (30.22±10.94) U/L, P<0.05, respectively];the histopathoiogic lesion scores were lower (P<0.05);the Ki-67 antibody and apoptosis of renal tubular epithelial cells were improved or reduced respectively;the expression of Bcl-2 protein was up-regulated (P<0.05). ConclusionThe subcapsular transplantation of MMCs can ameliorate renal function and repair kidney injury.

Objective To report the clinical results and the advantages/disadvantages of anterolateral thigh flap (ALT) and forearm flap (FAF) in reconstruction of head and neck defect after cancer ablation. Methods 20 FAFs and 12 ALTs were performed to repair the head and neck tumor ablation defects. Of the 20 FAFs, 7 were used for repair of the through and through buccal defects, 4 for circumferential bypopharyngeal defects, 2 for plate defects, 1 for parotid area skin defect, 4 for floor of the mouth defects, and 2 for defect, of the base of the tongue, while of the 12 ALTs, 3 were used for repair of the defects of the base of the tongue, 4 for plate defects, and 5 for the floor of the mouth and/or lower gum defects. Survival of the flaps, function of the recipient site, and impact to the donor site were compared between these two groups to analyze the advantages/disadvantsges and key technique details of these two flaps. Results 19 FAFs totally survived. Vascular crisis occurred in 2 cases of FAF, of which 1 flap survived after conservative treatment, while the other 1 developed partial necrosis. All the 12 ALTs survived, without vascular crisis. 2 of the 14 planed ALTs were abandoned and replaced by FAFs, of which 1 because of absence of the perforating branch and the other 1 because of injury of the perforating branch. Secondary defects of the ALTs could be closed primarily, while secondary defects of the FAFs should be closed with skin grafts. Conlusion Both ALT and FAF can be performed with high survival rate. Each has its own advantages. Selection of the donor site deponds on situation of the defect and purpose of the reconstruction.
