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 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.

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.

A 28-year-old female patient presented with indurated erythema and nodules on the right lower limb for 2 years,with mild itching and pain.Skin examination showed a well-circumscribed irregular dark red patch measuring about 10 cm × 5 cm in size on the extensor aspect of the right thigh.On the patch,there were scattered or densely distributed mung bean-to soybean-sized quasi-circular violaceous nodules with a smooth surface,which were hard on palpation.Subcutaneous nodules with medium hardness were found on palpation,and hyperpigmentation was observed on the surface of some nodules.Local skin temperature was increased,with tenderness on palpation.Histopathologically,mononuclear cells showed nodular or sheet-like distribution in the middle and upper dermis,some of which had pale-staining cytoplasm.Moreover,plenty of plasma cells were observed.Immunohistochemistry revealed that histiocytes were stained strongly positive for S100.The number of IgG4-positive plasma cells increased obviously,and was more than 50 per high-power field (× 200).The proportion of IgG4-positive plasma cells in IgG-positive plasma cells was 45％.Finally,the patient was diagnosed with cutaneous Rosai-Dorfman disease with increased IgG4-positive plasma cells.

Objective To study the influence of different starting time of hyperbaric oxygenation (HBO)therapy on acute cerebral infarction patients.Methods A total of 120 patients with first-time acute cerebral infarction were randomly and evenly divided into 4 groups:groups A,B,C and D.All the patients were treated with routine clinical regime.In addition,the patients in groups A,B andC started with HBO within 24 hours,between 24 and 72 hours and after 72 hours post-onset of the disease,respectively,while those in group D without HBO.All the patients were evaluated in terms of their neurological function and their perform- ante in activities of daily living,using the National Institutes of Health stroke survey(NIHSS)and Barthel In- dex(BI).Results At 14,28 and 90 davs after treatment,the patients in group A scored significantly better with NIHSS and BI than those in groups B,C and D(P0.05).No serious adverse reaction was found in the four groups.Conclusion The earlier the HBO therapy was started, the better the treatment.There will be no significant effects of HBO if it was started after 72 hours pust-onset of the disease.HBO therapy appears safe.

Objective To study the effects of infrasound of different frequencies and intensities on the levels of somatostatin(SS)and cholecystokinin(CCK)in rat duodenal mucosa.Methods A total of 140 male Sprague- Dawley rats were randomly divided into a control group,an 8 Hz-90 dB group,a 8 Hz-130 dB group and a 16 Hz- 130 dB group.The experimental groups were exposed to infrasound of 8 Hz-90 dB,8 Hz-130 dB or 16 Hz-130 dB,re- spectively,for 2 hours a day,and the control group was put under sham infrasonic exposure.After being exposed for 1, 7,14,21 and 28 days,7 rats were randomly selected from each group and underwent SS and CCK levels detection in duodenal mucosa by microarray radioimmunity method.Results Compared with the control group,the SS and CCK levels of duodenal mucosa did not change significantly after exposure for 1 day.The SS and CCK levels of duodenal mu- cosa significantly increased in 8 Hz-90 dB group,8 Hz-130 dB group and 16 Hz-130 dB group after exposure for 7,14, 21 and 28 days(P
