Objective To determine the distribution and antibiotics resistance characteristic of pathogens in urinary tract infections in aged female diabetics patients and provide scientific basis for clinicians in selecting effective antibiotics. Methods Pathogenic bacteria, isolated from specimens of 107 elderly female diabetic cases with urinary tract infections, were identified and drug susceptibility tests were performed by VITEK-32 analysator. Results Among all 107 kinds of isolated bacteria,the ratio of gram-negative bacteria was 74. 8% ( 80/107 ), predominated by Escherichiacoli ( accounting for 48. 6% [52/107] ); the ratio of gramposition bacterias was 13. 1% (14/107) and eumycetes was 12. 1% (13/107). In antibiotic resistance analysis,the gram negative bacteria showed higher drug-resistance to the some common-antibiotics, such as ampicililin,cefazolin,cefuroxime-sodium and cefuroxime axetil ( ＞ 70. 0% ), while they were sensitive to imipenem and amikacin( ＜ 10. 0% ). The gram positive bacteria were most sensitive to vancomycin (0%), followed by Linezolid(7.7% ). Conclusion Escherichiacoli were the major pathogenic bacteria in urinary tract infections in aged female diabetic patients, with higher drug resistance. Therefore, drug resistance monitoring should be carried out according to the variety of pathogenic bacteria so as to guide rational use of antibiotics and decrease drug resistance.

Objective Collecting the loosening periprosthetic interface-membrane, to discuss the mechanism of hip arthroplasty loosening. Methods The periprosthetic interface tissues of 29 hip arthroplasty revision cases from February 1995 to December 2003 were collected. The retrieved periprosthetic interface tissues were detected by immunohistochemistry. Some of them were studied by electronic microscope. Results (1)Transmission electronic microscope examination: the mitochondria swell. There were some substantia like lipid in the plasm of macrophages. Wear particles could be seen under scaning electronic microscope.(2)Immunohistochemistry: there were 22 IL-1? positive cases in cells of interface membrane. There were 29 IL-6 positive cases in cells of interface membrane. There were no positive results in TNF-? test. Conclusion (1)The wear particles of arthroplasty are important factors which cause biological reaction.(2)The interface membranes contain cytokine IL-1? and IL-6, which may play an important role in periprosthetic osteolysis and arthroplasty loosening.

Background and purpose:It has been demonstrated that radical prostatectomy for patients with oligometastatic prostate cancer may contribute to improving local control of prostate cancer and overall survival by several retrospective studies. Perioperative complications play an important role in determining whether radical prostatectomy is appropriate for patients with oligometastatic prostate cancer. This study aimed to discuss the recurrence rate and the sever-ity of perioperative complications, and the primary curative effect of radical prostatectomy on oligometastatic prostate can-cer patients.Methods:A total number of 247 patients who received radical prostatectomy were recruited in the study from Jul. 2015 to Jan. 2016, including 25 patients with oligometastatic prostate cancer and 222 patients with localized prostate cancer. Patients with perioperative complications in both groups were graded with the Clavien-Dindo grading system. The proportion of PSA decline and the rates and severity of perioperative complications were analyzed in both groups.Results:The cases of prostate specific antigen (PSA) decline in the oligometastatic group were 21 (84.0%), lower than the localized group with 212 cases (95.5%). There were 6 cases (24.0%) with postoperative complications in the oligometastatic group, including serious complications (Ⅲ or above) 1 case (4.0%), and 49 cases (22.1%) with postoperative complications in the localized group, including serious complications (Ⅲ or above) 7 cases (3.2%). The differences between the groups reached no statistical significance (P>0.05).Conclusion:Radical prostatectomy for patients with oligometastatic prostate cancer could be safe, effective, and appropriate, the risk of perioperative complications should not be one of the limiting factors.

OBJECTIVETo evaluate the efficacy of infliximab combined with surgery in the treatment of perianal fistulizing Crohn disease (CD).

METHODSClinical data of 15 patients with perianal fistulizing CD receiving infliximab combined with surgery in the Affiliated Hospital of Nanjing University of Chinese Medicine from March 2010 to June 2011 were analyzed retrospectively. One week after operation, all the patients received infliximab infusion thrice at weeks 0, 2, and 6. Crohn disease activity index (CDAI), perianal Crohn disease activity index (PDAI), body mass index (BMI), routine blood test and endoscopy were evaluated at week 0, 14. Adverse reactions and healing time were recorded.

RESULTSAt week 14, the response rate was 100% with 86.7% (13/15) complete responders. One patient had local improvement and one developed recurrent fistula. The mean healing time was 32.5 (20-45) d. Anorectal stenosis in 4 patients was significantly improved. At week 14, CDAI decreased to 114.0±90.3 from 230.5±97.5 after IFX treatment. PCDAI decreased to 2.8±3.2 from 9.9±3.4, and BMI increased to (21.5±3.0)kg/m(2) from (19.1±3.1)kg/m(2). C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet and neutrophil were significantly decreased from baseline (all P<0.01). Intestinal mucosa healed completely in one patient. There were no serious adverse events except hypokalemia in one patient and severe infusion reaction in another.

CONCLUSIONInfliximab combined with surgery is effective and safe for perianal fistulizing CD.

UNLABELLEDOBJECTIVE To compare the differences in the scores of blood stasis syndrome (BSS) in three subtypes of acute ischemic stroke (AIS) based on modified Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria, and to explore the influencing factors of BSS.

METHODSPatients with AIS were classified by modified TOAST criteria. The BSS score was determined in 418 patients of atherosclerosis thrombosis (AT), cardioembolism (CE), and small artery disease (SAD) subtypes. The BSS scores were compared in the three subtypes. Univariate analysis and multivariable Logistic analysis were carried out to analyze the influencing factors of BSS.

RESULTSAs for the BSS score, CE (120.08 +/- 14.91) > AT (79.56 +/- 11.43) > SAD (37.88 +/- 8.32), and there was statistical difference among different subtypes (P < 0.01). Univariate analysis indicated that age, heart disease, carotid stenosis, NIHSS, GCS, and multiple infarction positions had significant effects on BSS. Multiple Logistic regression analysis suggested that age (OR: 1.71, 95% CII: 1.13-2.74, P = 0.034), heart disease (OR: 2.05,95% CI: 1.52-4.15, P = 0.000), carotid stenosis (OR: 2.74, 95% CI: 1.65-4.55, P = 0.007), and multiple infarction positions (OR: 3.46, 95% CI: 2.16-6.62, P = 0.005) were independent influencing factors of BSS.

CONCLUSIONSDifferent TOAST subtypes of BSS had different BSS scores, which was helpful to indicate the reasons for BSS. Age, heart disease, carotid stenosis, and multiple infarction positions were independent influencing factors of BSS.

OBJECTIVETo investigate the effect of hairpin small interference RNA (shRNA) on mdr1 and GSTpi protein expression in multidrug resistance human leukemia cell line K562/A02.

METHODThe shRNAs were synthesized targeting the coding region sequences of mdr1 (79 - 99 nt) and GSTpi (308 - 327 nt) respectively, and cloned to plasmid pSilencer2.1-U6 neo. The cloned products pSilence mdr1 and pSilence GSTpi were transfected into K562/A02 cells. Western blot and immunofluorescence analysis were used to detect the effectiveness and the specificity of the gene silence. 50% inhibition concentration (IC(50)) of doxorubicin (ADM) on K562/A02 cells was determined by MTT method.

RESULTpSilence mdr1 and pSilence GSTpi reduced the expression of P-gp and GSTpi protein from 0.75 +/- 0.02 and 0.54 +/- 0.02 to 0.48 +/- 0.05 and 0.39 +/- 0.02 (P < 0.01) respectively, with no effect on alpha-tubulin expression in comparison with the mock treatment. Transfection of pSilence lamin A/C into K562/A02 decreased lamin A/C expression but had no effect on the expression of P-gp and GSTpi. Immunofluorescence assay also showed that shRNAs significantly reduced the P-gp and GSTpi positive cells from (71.25 +/- 9.65)% and (81.25 +/- 6.49)% to (35.25 +/- 5.97)% and (41.25 +/- 4.43)% (P < 0.01), respectively, compared with the mock treatment. The resistance indexes after transfection were decreased to 8 (pSilence mdr1) and 10 (pSilence GSTpi) respectively from 23 (mock transfection) (P < 0.01).

CONCLUSIONThe shRNA could effectively and specifically reverse the multidrug resistance on K562/A02 cell line.
