Objective To investigate the correlation between the expression of STAT3 and MMP-2 in human pancreatic cancer,and to probe the mechanism by which STAT3 signal pathway regulates the expression of MMP-2 in pancreatic cancer cells.Methods Immunohistochemistry was used to detect the expression of STAT3,phosphorylated STAT3(p-STAT3)and MMP-2 in pancreatic cancer tissues of 34 cases and normal pancreatic tissues of 10 cases.Correlation between the expression of STAT3、p-STAT3 and MMP- 2 were statistically analyzed.Human pancreatic cancer cell lines SW1990 was cultured.AG490,an inhibitor of the upstream Janus kinase(JAK)of STAT3 was added into the culture medium.Electrophoretic mobility shift assay(EMSA)was used to detect STAT3 DNA-binding activity in SW1990 cells.Western blot was used to detect the expression of STAT3,p-STAT3 in SW1990 cells.In addition,the protein and mRNA expression of MMP-2 in SW1990 cells were determined by Western blot and RT-PCR,respectively. Results Immunohistochemistry revealed that the expression rate of STAT3,p-STAT3 were both higher in pancreatic cancer tissues than in normal pancreas tissues(P

Objective To investigate the application of venereal disease research laboratory(VDRL) test and toluidine red unheated serum test(TRUST) in syphilis laboratory diagnosis.Methods Serum,plasma and cerebrospinal fluid (CSF) in syphilis patients and healthy controls were measured by VDRL and TRUST.Results The VDRL detection results in serum and CSF sepcimens were generally higher than the TRUST detection results by 1-2 titers,while in plasma specimen,the VDRL detection results were generally lower than the TRUST detection results by 1-2 titers than TRUST when using plasma specimen.In addition,the VDRL detection in normal control serum and plasma specimens all appeared different degrees of false positive,but in the detection of normal control CSF,the results of TRUST and VDRL were consistent.Conclusion TRUST is more suitable for serum and plasma specimens,and CSF is suitable for the CSF specimen,but not suitable for serum and plasma detection.

OBJECTIVETo observe the clinical effect of low-dose once-daily tadalafil combined with Shuganyiyang Capsules in the treatment of mild-to-moderate erectile dysfunction (ED).

METHODSNinety patients with mild-to-moderate ED were equally randomized to groups A, B and C to receive Shuganyiyang Capsules, tadalafil, and tadalafil + Shuganyiyang Capsules, respectively. The scores of the patients on IIEF-5 and SF-PAIRS (15-Item Short Form of Psychological Interpersonal Relationship Scales) were recorded before and at 1 and 3 months after treatment.

RESULTSThe IIEF-5 scores of groups A, B and C were 10.13 +/- 1.55, 11.00 + 1.60 and 10.73 +/- 1.91 before treatment, and 13.77 +/- 2.11, 17.77 +/- 2.13 and 17.17 +/- 3.84 at 1 month after treatment, significantly higher in B and C than in A (P <0. 001) , but with no remarkable difference between B and C (P =0. 411). At 3 months after treatment, the IIEF-5 scores were 15.77 +/- 2.05, 18.07 +/- 2.24 and 19.37 +/- 3.76 in the three groups, dramatically higher in B and C than in A (P <0.001) as well as in C than in B (P<0.05). The scores on sexual self-confidence, sexual spontaneity and time concerns in SF-PAIRS were 3.90 +/-0.80, 8.67 +/- 1.94 and 14.43 +/- 1.92 before medication, 5.83 +/- 1.02, 9.90 +/- 1.75 and 11.17 +/- 1.68 at 1 month and 6.73 +/- 0.98, 11.07 +/- 2.08 and 10.67 +/-1.60 at 3 months after medication in group A; 4.17 +/- 0.87, 9.37 +/-1.43 and 14.47 +/-1.57 before medication, 6.47 +/-0.78, 10.83 +/- 2.18 and 10.20 +/-1.56 at 1 month and 6.83 +/-0.91, 11.30 +/- 1.88 and 9.47 +/- 1.57 at 3 months in group B; and 4.23 +/-0. 94, 9.50 +/- 1.89 and 14.67 +/- 2.91 before medication, 8.03 +/- 1.67, 13.43 +/-1.10 and 9.70 +/-1.21 at 1 month and 8.93 +/- 1.78, 14.70 +/- 1.26 and 8. 87 +/- 0. 97 at 3 months in group C. Compared with the baseline, the SF-PAIRS scores of the three groups were all significantly improved after treatment (P <0. 05) , and markedly higher in C than in the other two groups (P <0.05).

CONCLUSIONLow-dose once-daily tadalafil combined with Shuganyiyang Capsules is obviously effective in the treatment of mild-to-moderate ED, which not only improves the patients'erectile function, sexual self-confidence and sexual spontaneity, but also reduces their time concerns.

Objective To evaluate the accuracy of high-aensitivity C-reactive protein (hs-CRP) in the prediction of perioperative cardiovascular accidents (CVAS) in patients with diabetes mellitus. Methods Ninetyone type 2 diabetic patients undergoing elective non-cardiac surgery were divided into 3 groups according to their blood concentrations of hs-CRP: low-concentration group ＜ 1.0 mg/L ( group Ⅰ , n = 9); median-concentration group 1.0-2.9 mg/L (group Ⅱ ,n= 16) and high-concentration group 3.0-10.0 mg/L (group Ⅲ ,n =66). Risk factors for perioperative CVA were analyzed using Spearman rank correlation analysis. Various risk factors including sex, age, ASA physical status, BMI, NYHA claasification, smoking history ,preoperative ECG changes, duration,treatment and complications of diabetes mellitus, hypertension and blood lipids were correlated with perioperative CVA. The risk factors of which P values were less than 0.05 would enter the binary logistic regression analysis to stratify CVA-related risk factors. Area under the ROC curve was used to analyze the accuracy of the risk factors in prediction of perioperative CVA. Results The incidences of perioperative CVAs were 0, 31% and 35 % in Ⅰ ,Ⅱ and Ⅲ groups respectively. It was determined by Spearman rank correlation analysis that preoperative ECG,NYHA classification, age, preoperative cardiovascular color doppler ultrasound, blood hs-CRP concentration and ASA classification of physical status were important risk factors ( P ＜ 0.05 or 0.01 ). Binary logistic regression .malysis indicated that preoperative ECG, NYHA classification and age were highly related to perioperative CVA (P ＜0.05 or 0.01).The area under ROC curve of preoperative ECG, NYHA classification, age and blood hsCRP concentration was 0.855, 0.755, 0.702 and 0.605 respectively. Conclusion The accuracy of blood concentration of hs-CRP in prediction of perioperative CVA in patients with diabetes mellitus is lower than that of the preoperative ECG, NYHA classification or age.

Objective To investigate the mechanism of quinolone resistance in Psendomonas aeruginosa.Methods The minimum inhibitory concentrations (MICs)of ciprofloxacin and levofloxacin with and without carbonylcyainde-m-chlorophenylhydrazone(CCCP)were determined by agar dilution method.Polymerase chain reaction(PCR)and DNA sequencing were used to study the mutations in quinolone resistance-determining region of gyrA and parC genes.The strains were genotyped by enterbacterial repetitive intergenie consensus-PCR(ERIC-PCR).Results Sixteen quinolones-resistant Pseudomonas aeruginosa strains were obtained.The MICs of ciprofloxacin and levofloxacin were not reduced significantly by adding CCCP.Thr-83→Ile of gyrA and Ser-87→Leu of parC were found simultaneously in 16 strains of resistant Pseudomonas aeruginosa.Analysis of ERIC-PCR products indicated that 16 quinolone-resistant strains had an identical band pattern which was different from that seen in the sensitive strains.Conclusion Mutations in gyrA and parC may be the main mechanism of quinolone resistance in clinical isolates of Pseudomonas aeruginosa.

Objective: To obtain the antibody against N terminal of 1A6/DRIM, and thereafter get the profile of 1A6/DRIM expression in different cell lines. Methods: The N terminal of 1A6/DRIM (aa 577 714) was cloned into pGEX 4T 3. Multiple antigenic peptides (MAPs)(aa638 661) was synthesized as the antigen with Fmoc/PyBOP method. Rabbits were immunized by injecting the MAPs and the immunized sera were analyzed with ELISA and Western Blot. The Western Blot and immunofluorescence were performed to analyze the expressing profiles of the 1A6/DRIM in different tumor cell lines. Results: The antibody specifically recognized the full length of 1A6/DRIM as a 310 kDa band, which was also recognized by C terminal monoclonal antibody shown by Western Blot. 1A6/DRIM is expressed in multiple tumor cell lines and mainly located in the nuclei. Conclusion: Preparation of the antibody with MAPs is a useful technique when the fusion proteins can not be induced in E coli . The antibody we got via MAPs has supplied a good tool for further studies on the functions of the novel gene 1A6/DRIM.
