ObjectiveTo analysis the different types of bacteria in patients with a varying severity of acute cholangitis.Methods241 patients who presented with actue cholangitis between Jan 2008 to Oct 2011 to our hospital were retrospectively studied.These patients were divided into three groups according to the Tokyo Guideline.The bile specimens were obtained intraoperatively.The parameters were compared by SPSS 16.0 package program for statistical analysis.Results75.1 percent of the patients were positive for bacteria in the bile.There were 241 strains of bacterium which included 139 Gram-positive bacteria,99 Gram-negative bacteria and 6 strains of microzyme.Escherichia coli,Enterococcus faecalis,Enterococcus casseliflavus,Pseudomonas aeruginosa and Klebsiella species were the most frequently isolated bacteria.The positive rates for bacteria were significantly different between patients with mild and severe cholangitis (P＜0.05).There was no significant difference between patients with moderate and mild cholangits (P=0.141),or moderate and severe cholangitis (P=0.647).Gram-negative bacteria were more common than Gram- positive bacteria in patients with moderate and severe acute cholangitis (P＜0.05).In patients with moderate and severe acute cholangitis,there was more patients with multiple and mixed bacterial infection.ConclusionsEscherichia coli and Enterococcus species were more common in patients with acute cholangitis.The positive rate of bacteria in the bile in severe acute cholangitis was higher than that in mild acute cholangitis.In patients with moderate and severe cholangitis,Gram-negative bacterial infections and multiple and mixed bacterial infections were more common.

Objective To investigate the clinical significance of lymphatic mapping and sentinel lymph nodes (SLNs) biopsy in the diagnosis and treatment of gastric cancer. Methods A retrospective analysis was carried out based on the data of 46 patients who had received D2 gastrectomy from January 2003 to June 2006. The SLNs stained by methylene blue were resected for biopsy. Results The success rate of SLNs biopsy was 83% (38/46). The sensitivity, false-negative rate, accuracy, specificity, negative predictive value and positive predic-tive value of SLNs were 69% (18/26), 31% (8/26), 79% (30/38), 100% (12/12), 60% (12/20) and 100% (12/12). The sensitivity, accuracy and negative predictive value were 100% in patients with tumor in pT1 stage or TNM I stage, or with the diameters of the tumors under 4 era. The tumor site, and the degree of lymph node metastasis affected the success rate of biopsy, and the invasion depth, clinical stage and the degree of lymph node metastasis affected the sensitivity, accuracy and negative predictive value of biopsy. Conclusions The application of sentinel lymph node biopsy using methylene blue in gastrie cancer is feasible. The sensitivity, accuracy and reliability are high in patients at early stage of gastric cancer.
