Objective To investigate the bacterial distribution and resistance to antibiotic of male urinary tract infections in China,2012.Methods The urine specimens from the tertiary hospitals and the second class hospitals were routinely isolated and identified.Disc diffusion test, MIC test and E -test were used to detect the antimicrobial sensitivity.Results All the clinical stains isolated from 557 tertiary hospitals and 232 second class hospitals.A total of 61293 pathogenic strains were co-llected from male urine specimen, which included E.coli 20357strains ( 33.2%) , E.faecalis 5280 strains ( 8.6%) , K.pneumonia 5249 strains (8.6%) and E.faecium 4516 strains (7.4%).In tertiary hos-pital, The top four bacteria were E.coli, E.faecalis.K.pneumonia and E.faecium, and in second class hospitals were E.coli, P.aeruginosa, K.pneumonia and E.faecalis.The resistant rate of E.coli, K.pneumo-nia and E.cloaecae strains to cefotaxime were above 70%.The resistant rate to levofloxacin were 63.8%, 40.9%and 35.7%, respectively.The 4.2%and 4.0%of E.faecium isolates were resistant to vancomycin and teicoplanin, respectively.The 1.1% and 2.8% of E.faecalis isolates were resistant to vancomyicin and teicoplanin, respectively.Conclusion E.coli were predominant organism in male urinary tract infections in China.There were some difference in bacterial distribution and resistance between the tertiary hospitals and second class hospitals.

OBJECTIVETo investigate the mRNA expression of bFGF and MMP-9 in gastric carcinomas and to find their correlation with tumor microvascular density (MVD), invasion, metastasis and patients survival.

METHODSIn situ hybridization and immunohistochemistry technique were used to test the expression of bFGF mRNA and MMP-9 mRNA and protein of CD34 in 105 specimens of gastric carcinoma.

RESULTSIn situ hybridization revealed that the positive rates of bFGF mRNA and MMP-9 mRNA were 60.95 and 58.1%, respectively; The mean MVD (46.09 +/- 11.52, 43.75 +/- 13.41 piece/0.72 mm(2)) in tumors with bFGF mRNA and MMP-9 mRNA positive expression was significantly higher than that (29.41 +/- 12.47; 33.45 +/- 13.92 piece/0.72 mm(2)) in tumors with their negative expression, respectively; The positive expression rates of bFGF and MMP-9 mRNA were correlated to invasion depth (r(s) = 0.211, P = 0.031; r(s) = 0.335, P = 0.001, respectively), growing pattern (r(s) = 0.324, P = 0.001; r(s) = 0.267, P = 0.006, respectively), vessel invasion (r(s) = 0.579, P = 0.001; r(s) = 0.209, P = 0.032, respectively), lymph node metastasis (r(s) = 0.405, P = 0.001; r(s) = 0.343, P = 0.001, respectively) and distant metastasis (r(s) = 0.474, P = 0.001; r(s) = 0.468, P = 0.001, respectively), but not correlated to tumor type (r(s) = 0.134, P = 0.173; r(s) = 0.103, P = 0.145, respectively) and differentiation (r(s) = 0.096, P = 0.332; r(s) = 0.102, P = 0.298, respectively); And then, the mean MVD in tumors with infiltrating type, stage T(3)-T(4), vessel invasion, lymph node metastasis and distant metastasis was significantly higher than that in tumors with expanding type (t = 10.105, P = 0.001), stage T(1)-T(2) (t = 5.961, P = 0.001), non-vessel invasion (t = 7.394, P = 0.001), non-lymph node metastasis (t = 3.819, P = 0.01) and non-distant metastasis (r = 10.578, P = 0.001); There was a positive relationship between MVD and bFGF mRNA and MMP-9 mRNA (t = 3.207, P = 0.002; t = 7.035, P = 0.001), respectively; the mean survival time in cases with positive bFGF mRNA and MMP-9 mRNA and MVD value >/= 39.5 was significantly shorter than that in cases with their negative expression and MVD value < 39.5.

CONCLUSIONSbFGF and MMP-9 promote angiogenesis in gastric cancer. Test of the expression of bFGF and MMP-9 may act as an useful index to determine angiogenesis, invasion, metastasis and patients survival.

Since Firstly isolated in 1986s,vancomycin resistant Enterococci (VRE) has spread throughout the United States,Europe and other places.Molecular detection methods(MDM) for VRE active surveillance can obtain test results quickly,helpful to prevent VRE infection.In different studies,there are many factors resulting in different sensitivity,specificity,positive predictive value (PPV),and negative predictive value(NPV) by different methods or the identical method.Here we present an overview about the research progress in pplymerase chain reaction based methods for rapid identification of VRE.

OBJECTIVETo discuss the therapeutic effect and toxicity of second line Hycamtin for lung cancer patients.

METHODSTen of these 21 patients had been treated with operation. All these 21 patients received second line Hycamtin treatment; given at the dose of 1.2 mg/m(2) per day, four consecutive days as one cycle and 21 days as one course. A total of 1 - 4 courses were given according to the patient's tolerance. Four of these 21 patients also received combination of cisplatin.

RESULTSAmong the 13 un-operated patients, two patients showed CR, six showed PR, three SD and two PD, giving an effective rate of 62%. Among the 8 operated patients, seven showed SD but one developed distant metastasis. The 1-year survival rate was 88%.

TOXICITYleukopenia I-II degree 14 (66.7%), leukopenia III-IV degree 5 (23.8%), thrombocytopenia III-IV degree 1 (4.8%) and one patient died of high fever and neutocytopenia. Nausea 8 (38.1%), vomiting 3 (14.3%) and diarrhea 2 (9.5%) alopecia 4 (19.1%). Were the other side-effects.

CONCLUSIONHycamtin is indicated for second line therapy for lung cancer giving tolerable toxicity.

OBJECTIVETo investigate the blockness effects of purified polyclonal anti-porin I antibody on N. gonorrhoeae adherence to genitourinary tract epithelia of BALB/c mouse.

METHODSPolyclonal anti GST-PI antibody was generated by immunizing rabbit with GST-PI fusion protein which was constructed and expressed by ourselves. The purified immunoglobulin G was obtained by ammonium sulphate deposition and DEAE cellulose chromatography. Mice model of gonorrhea was established. In order to evaluate the effects of PI-IgG on gonococcus adhesion to vagina mucus, the macroscopic and pathological assessing as well as gonococcus culture was employed after gonococcus challenge on PI-IgG immunized mice.

RESULTNo pus and pathological inflammation were observed on mice vagina mucus treated with 1 mg/ml PI-IgG 3 hours before gonococcus challenge. Gonococcus could not be detected in the smears and washing solutions from vagina. Pathological inflammation was found in mice treated with anti PI-IgG, in which the concentrations were lower than 1 mg/ml or the treated time was longer than 3 hours prior to gonococcus challenge.

CONCLUSIONThe purified anti PI-IgG can effectively inhibit the adherence and infection of gonococci to genitourinary tract epithelia of BALB/c mice. In addition, the blocking duration of anti PI-IgG is associated with antibody concentration.
