To determine the lysis spectrum of Yersinia enterocolitica bacteriophage phiYe-F10 and to analyze the relationship between the lysis ability of phiYe-F10 and the virulence gene of Yersinia enterocolitica. To observe the lysis ability of the phage phiYe-F10 to the different Yersinia strains with the double-layer technique. The strains used in this study including 213 of Yersinia enterocolitica and 36 of Yersinia pseudotuberculosis and 1 of Yersinia pestis. The virulence genes of these Yersinia enterocolitica (attachment invasion locus (ail) and enterotoxin (ystA, ystB) and yersinia adhesin A (yadA), virulence factor (virF), specific gene for lipopolysaccharide O-side chain of serotype O : 3 (rfbc) were all detected. Among the 213 Yersinia enterocolitica, 84 strains were O : 3 serotype (78 strains with rfbc gene), 10 were serotype O : 5, 13 were serotype O : 8, 34 were serotype O : 9 and 72 were other serotypes. Of these, 77 were typical pathogenic Yersinia enterocolitica harboring with virulence plasmid (ail+, ystA+, ystB-, yadA+, virF+), and 15 were pathogenic bacterial strains deficiency virulence plasmid (ail+, ystA+, ystB-, yadA-, virF-) and the rest 121 were non pathogenic genotype strains. PhiYe-F10 lysed the 71 serotype O : 3 Yersinia enterocolitica strains which were all carried with rfbc+, including 52 pathogenic Yersinia enterocolitica, 19 nonpathogenic Y. enterocolitica. The phiYe-F10 can not lysed serotype O : 5, O : 9 and other serotype Y. enterocolitica, the lysis rate of serotype O : 3 was as high as 84.5%. The phiYe-F10 can not lysed Yersinia pseudotuberculosis and Yersinia pestis. Yersinia phage phiYe-F10 is highly specific for serotype O : 3 Yersinia enterocolitic at 25 degrees C, which showed a typical narrow lysis spectrum. Phage phiYe-F10 can lysed much more pathogenic Y. enterocolitica than nonpathogenic Y. enterocolitica.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Proteomics is an emerging discipline developed on the basis of genomics.The fundamental techniques of proteomics include sample preparation,protein separation,protein identification and analysis,and its core techniques are two-dimensional gel electrophoresis and mass spectrometry.In recent years,proteomics has been used in researching the field of Mycobacterium tuberculosis(MTB).Proteomics promotes deep understanding of the pathogenesis of MTB and resistance mechanism via isolating,identifying and analyzing the whole-cell protein and secreted proteins.The development of new vaccine against MTB has showed some promising results based on proteomics.Some powerful early diagnostic markers have been discovered via analyzing the protein composition of MTB clinical isolates.Proteomics also applies to find potential new drug targets,and it has shown many valuable research productions in developing new an-ti-MTB drugs.In summary,the application of proteomics has built a solid foundation for the development of prevention,early diagnosis and treatment of tuberculosis.

Objective:To investigate the efficacy of double balloon enteroscopy (DBE) in the treatment of bleeding from small intestinal vascular lesion and risk factors of bleeding recurrence .Methods:From April 2013 to May 2020, at Air Force Medical Center, the clinical data of 65 patients with confirmed or suspected bleeding from small intestinal vascular lesion were retrospectively analyzed. The patients were divided into DBE treatment group (patients of Yano classification 1a and 1b received argon plasma coagulation, and patients of Yano classification 2 and 3 accepted combination of titanium clip and submucosal injection of lauromacrogol sclerosing agent) and non-DBE treatment group (traditional treatments such as stopping anticoagulant or antiplatelet drugs, blood transfusion, and iron supplementation). The bleeding recurrence of patients with single small intestinal vascular lesion between DBE treatment group and non-DBE treatment group, and patients with single or mulitiple vascular lesion of DBE treatment group were compared. Univariate analysis was used to analyze the clinical data of patients with or without recurrent bleeding. Multivariate logistic regression model was used to analyze the independent risk factors and protective factors of recurrent bleeding in small intestinal vascular lesion. Independent sample t test, chi-square test and Fisher exact probability method were used for statistical analysis. Results:Forty-four (25 of single vascular lesion and 19 of multiple vascular lesion) patients were diagnosed with small intestinal vascular lesions and received DBE treatment (DBE treatment group). Twenty-one patients with single vascular lesion accepted traditional treatment (non-DBE treatment group). The recurrent rate of bleeding in patients with single vascular lesion of DBE treatment group was lower than that in patients with single vascular lesion of non-DBE treatment group and patients with multiple vascular lesion of DBE treatment group (24.0%, 6/25 vs. 71.4%, 15/21 and 12/19), and the differences were statistically significant ( χ2=10.348 and 6.848, P=0.001 and 0.009). The results of univariate analysis showed that the proportion of blood transfusion, hypertension, complicated with valvular heart disease and DBE treatment in patients with rebleeding or not rebleeding from small intestinal vascular lesion was different with statistically significant (69.7%(23/33) vs. 37.5%(12/32), 51.5%(17/33) vs. 18.8%(6/32), 42.4%(14/33) vs. 12.5%(4/32) and 54.5%(18/33) vs. 81.2%(26/32), χ2=6.777, 7.628, 7.265, and 5.298, all P<0.05). The results of multivariate logistic regression analysis indicated that blood transfusion during the course of disease (odds ratien ( OR)=3.736, 95% confidence interval ( CI) 1.082 to 12.898, P=0.037) and complication with valvular heart disease ( OR=4.916, 95% CI 1.107 to 21.829, P=0.036) were independent risk factors of bleeding recurrence in patients with small intestinal vascular lesions. DBE treatment was the protective factor of bleeding recurrence in patients with small intestinal vascular lesion ( OR=0.214, 95% CI 0.057 to 0.808, P=0.023). Conclusions:DBE is effective in the treatment of small intestinal vascular lesion bleeding, especially for single vascular lesion. Blood transfusion during disease course and complication with valvular heart disease are independent risk factors for bleeding recurrence in patients with small intestinal vascular lesion.

?AlM: To evaluate the clinical effects and security of posterior chamber implantable Collamer lens ( lCL ) implantation in patients with extreme highly myopia.
?METHODS:ln this study, 18 patients ( 32 eyes ) with extreme highly myopic patients who had undergone posterior chamber lCLs implantation from July 2010 to July 2013 were evaluated. Diopter -10. 5 ~ 19. 0D, and astigmia -0. 5 ~4. 5DC. Changes in intraocular pressure ( lOP ) , refraction, visual acuity and corneal endothelium, anterior chamber depth, iris, high arch, lens were noted at 1d, 1wk, 1, 3mo and 1a after surgery respectively, and follow-up was of 1a.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
