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.

After the problems in military postgraduate information literacy education were analyzed, the construction of a systematic and coherent information literacy education course system for military postgraduates in close combination with their subjects was proposed by setting up multidimensional education target, designing three-stage foundation-subject-innovation course, combining traditional literature retrieval course and embedded professional course, combining case teaching, heuristic discussion and innovative talent information literacy training approach, by infiltrating the physical and virtual space both in and outside university, and by participating in the study and research activities of postgraduates.

ObjectiveTo investigate the clinical value of ATP bioluminescence tumor chemosensitivity assay (ATP-TCA) for recurrent and refractory non-Hodgkin lymphoma (NHL) specimens in vitro.Methods Thirty-four freshlytaken recurrent andrefractoryNHL specimens weretestedin vitro for cancer chemosensitivity by ATP-TCA.ResultsDrug sensitivity of NHL specimens had heterogeneity.Different drugs had different tumor growth inhibition ratio in vitro.Response rate (RR) of the patients receiving chemotherapy according to in vitro assay was 82.4 ％ (28/34),complete response rate (CR) was 52.9 ％ (18/34).In DICE group RR was 60.0 ％ (18/30),CR rate was 33.3 ％ (10/30).In GDP group RR was 62.3 ％ (33/53),CR rate was 26.4 ％ (14/53).In ATP-TCA group RR was significantly higher than those in DICE and GDP groups (x2 =3.93,P =0.047; x2 =3.98,P =0.046).ConclusionThe results of ATP-TCA assay are correlated well with clinical treatment responses.The assay may be an important and useful method for individual-based chemotherapy of cancers.

OBJECTIVETo evaluate the clinical results after arthroscopic rotator cuff repair using a suture-bridge technique in late middle-aged adults.

METHODSA retrospective analysis of 30 patients with rotator cuff tears, who were treated consecutively between December 2012 and December 2013 at our clinic, was carried out to evaluate the outcome of arthroscopic suture-bridge technique. The visual analogue scale (VAS), the range of motion (ROM), the rating scale of the University of California at Los Angeles (UCLA), and the shoulder index of the American Shoulder and Elbow Surgeons (ASES) were determined as the evaluation criteria.

RESULTSThe mean follow-up period was 13 months. The follow-up rate was 100%. The study included 0 small, 16 medium, 12 large and 2 massive rotator cuff tears. At the latest follow-up, the VAS score decreased significantly from preoperative 6.3±3.2 to 0.8±1.4 at rest,and from preoperative 7.7±2.1 to 1.7±1.6 during motion. The UCLA score improved significantly from 15.1±4.6 preoperatively to 31.2±5.0 at follow-up. The ASES shoulder index improved significantly from 30.2±16.0 preoperatively to 80.4±13.0 at follow-up. The ROM improved significantly. The satisfactory rate was 94%. There were no complications.

CONCLUSIONThe results of this study indicate that the arthroscopic suture-bridge technique is an effective and reliable treatment for patients with rotator cuff tear in late middle-aged adults.

BACKGROUND: Classic isolation method of bone marrow mesenchymal stem cells (BMSCs) is Percoll density gradient centrifugation. Blood cell component was removed. However, this method is complicated. Preparation density was needed when isolating dog bone marrow. Moreover, centrifugation was frequent, which had a great damage to cells. OBJECTIVE: To establish methods of the isolation, proliferation, culture and osteoinduction of canine BMSCs, and observe the in vitro proliferation and ability to osteoinduction differentiation. METHODS: 10 mL bone marrow was extracted from dog posterior superior iliac spine, heparin anticoagulation, diluted using Hanks juice, treated with 1.077 g/mL Ficoll solution 3 mL, and centrifuged at 2 000 r/min for 20 minutes. Karyocytes were absorbed to form white cloudlike layering interface, and then centrifuged twice using DMEM supplemented with fetal bovine serum, incubated at 12×10~4/cm~2 at 37 ℃ in a 5% CO_2 incubator. Following subculture, cells were incubated in DMEM containing dexamethasone, β-sodium phosphoglycerol and ascorbic acid 2-phosphate. Immunocytochemical staining and immunofluorescence staining were utilized to detect osteocalcin, osteopontin and type Ⅰ collagen expression in osteoblasts. Alkaline phosphatase staining and alizarin red staining were performed. RESULTS AND CONCLUSION: 1.077 g/mL Ficoll density gradient centrifugation was used to isolate karyocytes that were significant compared with Percoll solution. Obtained BMSCs had high purity, good growth and the mean doubling time was 24 hours. Following in vitro osteogenic incubation of dog BMSCs, osteocalcin, osteopontin and type Ⅰ collagen showed positive expression. Alkaline phosphatase staining demonstrated bluish-green cytoplasm. Alizarin red staining showed red nodes in extracellular matrix, and could differentiate into osteoblasts in vitro.

11.0 for the pH of reaction solution,65℃～75℃for the reaction temperature,and 1:1.7 for the mass ratio of corn(dry weight)to FeCl_3?6H_2O.The corn polysaccharide-Fe(Ⅲ)complex synthesized with the optimized process was stable,with good solubility in water.The assay of Fe(Ⅲ)was 39.86%,40.20%and 40.17%,respectively for three batches of products.The RSD was

control group from the high to the low. When the typeⅢand type Ⅳglomerular function was changed (BUN and BCr in high value),the drainage quantity of the enzymes evidently increased.Conclusions Urine enzyme series can sensitively reflect the damage of renal tubules in early stage, even if BUN and BCr value is on the normal level , and the drainage quantity of these enzymes are changed more or less, which show that renal tubule damage exists. The value of BUN and BCr is positively correlated with the drainage quantity of these enzymes.the more urine enzymes are drained out, the more renal tubule function is involved, therefore, the more renal globe function is damaged.
