OBJECTIVE: To explore the three-dimensional ultrasound locatization in endoscopic thyroidectomy for multinodular goiter (MG). METHOD: Thirty two patients with MG underwent ET via bilateral areolar approach. Preoperative ultrasonography were used to locate lesions and marked in the 3-D map designed by us. Dur ing ET procedure, surgery skills were adopted to expose inferior pole of thyroid, glands in the area of Berry ligament or (and) upper pole were retained according to the preoperative location map. RESULT: According to the preoperative ultrasonic orientation, 3 lobectomy were performed in 15 cases of unilateral lesions, 12 subtotal thyroidectomy were performed in 17 cases of bilateral lesions, and 5 patients performed unilateral lobectomy add partial thyroidectomy. All patients had successful ET using bilateral areola approach. No conversions to open surgery, no complication occurred, and no nodules were found missing in the postoperative ultrasonography examinations. CONCLUSION Preoperative ultrasonic orientation and intraoperative operating skills are contributing to a successful ET for MG.

ObjectiveTo evaluate the accuracy of EUS,EUS-guided fine needle aspiration ( EUSFNA) and targeted biopsy in the diagnosis of wall-thickened gastric lesions with negative malignant results ofendoscopic biopsies.MethodsA retrospective study was carried out in 57 patients who were found with thickened gastric wall of negative malignant endoscopic biopsies and underwent EUS from January 2008 to December 2010 in our hospital.Compared the EUS findings with the surgical results and follow-up status.The diagnostic yield of EUS was characterized by the disappearance of the layers or the changes of thickness of gastric wall,the characteristics of echo imaging,and the results of EUS-FNA or EUS targeted biopsy were recorded to evaluate the value of EUS.ResultsOf 57 cases,gastric cancer was confirmed in 19,lymphoma in 10,dysplasia in 1,Menetrier's disease in 1 and inflammatory changes in 26.EUS could clearly demonstrate the changes of gastric wall including the thickness and the changes of layers,with the accuracy rate of 73.07％ ( 14/19 ) on gastric cancer.EUS diagnosed gastric cancer in 26 cases,in which 14 (53.8％) were confirmed by pathology.Gastric lymphoma was suspected by EUS in 20 cases,in which 10 (50.0％ ) were proved.EUS-FNA was conducted in 19 cases,with positive result in 9 (accuracy rate 50％ ).EUS-guided targeted deep biopsy or piece-meal biopsy were performed in 10 cases,with 8 malignant results.ConclusionEUS with/without EUS-FNA is not a golden standard for the diagnosis of gastric lesions in thickened gastric wall,yet it still has some significance.

To investigate the association between red blood cell volume distribution width (RDW) and osteophytes.
 Methods: This cross-sectional study was conducted in the Department of Health Examination Center of Xiangya Hospital, Central South University in Changsha, Hunan Province, China. A total of 8 334 subjects were included in this study. The severity of osteophytes was graded using the criteria of the Osteoarthritis Research Society International (OARSI). Osteophytes incident was defined as at least one side of the knee had a osteophytes grade ≥1. According to the quartiles of the RDW level, the subjects were divided into 4 groups. Multivariate logistic regression analysis was used to calculate the odds ratio (OR) and the 95% confidence interval (CI) of the knee osteophytes incidence between each RDW group and the lowest level group. Tests for linear trends were conducted based on logistic regression using a median variable of RDW level in each category.
 Results: Quartile 1 (Q1), RDW≤9.78; Q2, 9.7813.10. The multivariable adjusted ORs (95%CI) of the prevalence of osteophytes were 1.38 (1.06 to 1.79) in the second percentile interval, and 1.27 (0.97 to 1.66) and 1.50 (1.15 to 1.94) in the third and fourth percentile interval, respectively. Test for linear trends suggested that there was a positive association between the RDW level and the risk of knee osteophytes incidence (P=0.019).
 Conclusion: The risk of osteophytes incidence increases with the increasing RDW levels.
