Objective To evaluate the pattern of lateral cervical metastases and to investigate the risk factors for lateral cervical lymph node metastases in paoiuary thyroid carcinoma patients with clinical negative lateral neck lymph node.Methods 73 patients with paoiuary thyroid carcinoma who underwent prophylactic lateral neck dissections(level Ⅱ-Ⅵ or level Ⅱ-ⅣandⅥ) were reviewed retrospectively on their medical records paoiuary thyroid carcinoma.None of patients in this study had a clinically positive lymph node.Neck dissection specimens were obtained for histological analysis for node metastasis with respect to the individual neck levels.Results Occult metastases in lateral neck were observed in 12(16.4 ％)patients.9.6 ％,0,13.6 ％,9.6 ％,0,4.8 ％ and 42.4 ％ patients had histologically positive lymph nodes in levels Ⅱa,Ⅱb,Ⅲ,Ⅳ,Va,Vband Ⅵ respectively.In multivariate analysis,lymphatic metastases in level Ⅵ was associated with lateral neck metastasis(OR=7.3,P=0.020)in cN0 patients with paoiuary thyroid carcinoma.Conclusion Levels Ⅲ,Ⅱa and Ⅳwere the most common stages showing occult lymph node metastases.Prophylactic lateral neck dissections may be omitted in the treatment of cN0 PTC patients ff level Ⅵ lymphatic metastases are not found on histological exam.

ObjectiveTo research the endothelial dysfunction and early changes in arterial elasticity in patients with hyperlipidemia and effects of atorvastatin on these changes.Methods40 patients with hyperlipidemia but without any treatment in our hospital were selected as a study group,and 30 healthy people were selected as control group.Use the Flow mediated dilation,FMD detection which bases on the echo-trackingtechnology,eTRACYING to evaluate the right brachial atherosclerosis parameters and vascular diastolic parameters,including the pressure strain elastic modulus(Ep) ;stiffness index (β) ;compliance (AC) ;FMDs and FMDd.The study group take atorvastatin 20mg per day,then retested above parameters and TC,LDL-C after 12 weeks and analyzed all parameters.ResultsThe values of β and Ep in study group are significantly higher than the control group (all P ＜ 0.001 ),but AC;FMDs and FMDd are significantly lower than the control group( all P ＜ 0.001 ).The results of the study group after the treatment of atorvastatin are as follwing:TC,LDL-C,β and Ep are lower than before,AC,FMDs and FMDd are higher than before;and the differences are of significance in statistics ( all P ＜ 0.001 ).ConclusionHyperlipidemic patients had shown the vascular endothelial injury and vascular early hardening before the abnormal changes in intimal,but the atorvastatin intervention could reverse these changes.

Objective To evaluate if Ⅵ region lymph nodes metastasis status can be a reliable indicator in prediction of lateral lymph nodes metastasis in papillary thyroid carcinoma (PTC) with negative cervical lymph nodes (cN0).Methods Retrospectively reviewed the medical records from January 2003 to October 2011 of 73 patients with PTC who underwent prophylactic lateral neck dissection (Ⅱ-Ⅴ region or Ⅱ-Ⅳ region).The relationship between cervical lymph nodes metastasis and lateral lymph nodes metastasis was assessed.Results The rate of lateral lymph nodes metastasis was 16.4％(12/73).The rate of Ⅵ region lymph nodes metastasis was 42.5％(31/73).Multivariate analysis showed that Ⅵ region lymph nodes metastasis was the risk factor of lateral lymph nodes metastasis in cN0 patients with PTC(OR =7.3,P=0.020).Conclusion Ⅵ region lymph nodes metastasis status can be a reliable indicator of lateral lymph nodes metastasis in cN0 patients with PTC.

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.
