Objective:To investigate the role of transcription factor SP1 decoy oligodeoxynucleotides(ODN) on expression of ? Gal in SV-40-PED cells.Methods:Immortalized porcine aortic endothelial cells of the PED line were cultured and transfected with ?1,3galactosyltransferase(?1,3GT) specific decoy ODN.Cells transfected with mismatch ODN was used as negative controls.Twenty-six hours later the cells were collected.The expression of ? Gal was determined with fluorescence microscope and Western blot.The expression of ?1,3GT mRNA was examined by RT-PCR.Results:Fluorescence microscopy observed the decreased fluorescence of ? Gal after decoy ODN transfection.Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was(48.2?0.9).It is 52.6% of the mock group(P0.05).Conclusion:?1,3GT gene reduce actually occurs following transfection of decoy ODN.Porcine endothelial cells can be the targets of decoy ODN.

Objective To investigate the genotype of carbapenem-resistant Acinetobacter baumannii(CRAB) acquired from intensive care units (ICUs) environment in Shanghai hospitals and to evaluate the gene homology of CRAB isolated from patients and environment in ICUs in Shanghai hospital.Methods Sixty-one CRAB isolated from ICUs environment in Shanghai hospitals and 14 strains isolated from ICUs patients in S hospital were typed by REP-PCR based DiversiLab system.Results There were 7 types of the CRAB isolated from ICUs environment in Shanghai hospitals.Type G1 was the dominant type,accounting for 75.4％ of all CRAB,mainly in 13 hospitals in Shanghai.The percentage of the 7 types CRAB strains were 75.4％,13.1％,3.3％,1.6％,1.6％,3.3％ and 1.6％,respectively.Except for 1 strain of type G6 isolated in D hospital,type G1 CRAB was identified in every hospital which was isolated CRAB.There were 25 strains isolated from patients and environment in S hospital ICUs,which were divided into 4 types.Type G1 was the dominant type mainly distributed in SICU and CICU,including 9 from patients and 8 from environment.The distribution diagram of environmental and patients' strains indicated that the patients in adjacent bed isolated G1 CRAB in SICU and a patient in CICU and its surrounding environment both isolated G1 CRAB.Conclusion Type G1 is the dominant type in ICUs environment in Shanghai hospitals.There are inter-hospital transmission of CRAB in ICUs environment and highly homology of CRAB isolated from patients and environment in ICUs in Shanghai hospitals.Active surveillance of infection and colonization by CRAB,together with implementation of enhanced control strategies should be taken to eradicate CRAB in ICU environment.

Objective To study the characteristics of dynamic susceptibility-contrast(DSC)MR perfusion curves,color images and perfusion values in pre-operative brain metastasis.Methods Twenty- eight brain metastases underwent DSC MR perfusion imaging by using a first-pass T_2~* echo-planar sequence. The patients' data were transferred to on-line workstation.Time-signal intensity curves,color perfusion maps and rCBV,rMTT values in both tumor parenchyma and peri-tumor edema were analyzed,and independent t- test was used and P0.05).Conclusion Different originated brain metastases have nearly same characteristics in DSC MR perfusion imaging.

Melatonin has been reported to inhibit hepatic fibrosis and the mechanism may be correlated to its anti-oxidant effect.Nevertheless,the mechanism is not completely identified.This study was conducted to investigate the effects of melatonin on TGF-β1/Smad signaling pathway in liver fibrosis in rats.The liver fibrosis model was made by the subcutaneous injection of CCl4.The liver pathology changes were detected using hematoxylin and eosin (H&E) staining and Van Gieson (VG) staining.Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were measured with an autoanalyzer.Glutathione peroxidase (GPx) activities and levels of malondialdehyde (MDA) and hydroxyproline (Hyp) in liver were evaluated by spectrophotometry.Expression levels of TGF-β1,Smad2/3,phosphorylated Smad2/3 (p-Smad2/3) and Smad7 in liver were detected by immunohistochemistry and Western blot analysis.Results showed that melatonin suppressed CC14-induced liver fibrosis,along with an improvement in histological changes,significant decreases in pathologic grading sores and obvious decreases in Hyp levels in liver.Melatonin improved liver function indicated by decreased serum ALT and AST activities.In addition,melatonin exerted its anti-oxidant effects,as supported by decreased MDA levels and increased GPx activities in liver.Furthermore,melatonin inhibited TGF-β1/Smad pathway,as evidenced by decreased TGF-β1,Smad2/3 and p-Smad2/3 expression and increased Smad7 expression in liver.In conclusion,melatonin may suppress CCl4-induced hepatic fibrosis in rats via inhibiting TGF-β1/Smad pathway.It is possible for melatonin to be a potential reagent to treat and cure liver fibrosis.

Objective To study the anti-fatigue effect of Cynomorium songaricum flavone(CSF)on old rats.Methods50 old male Wistar rats were randomly divided into the control group(no swimming,no drugs),single swimming group(swimming,given saline by gavage),and three swimming plus CSF groups(swimming,given CSF 20 g/kg weight,10 g/kg weight and 5 g/kg weight respectively),total five groups with 10 animals in each group.Animals swam with free swimming in endless cycles water 30 minutes once every day for 10 days.The level of monoamine oxidase(MAO) and glutathione peroxidase(GSH-px) in blood of animals were examined by MAO kit,GSH-px kit and ultraviolet spectrophotometer at 11th day.ResultsCompared with single swimming group,the body weights of swimming plus CSF groups increased significantly by 12.9%,80.6% and 200% respectively(P<0.01);swimming times before sinking increased by 19.4%,29% and 48.4%;sinking times of each rat(time/10 min) decreased by 17.8%,43.2% and 72.9%;total swimming times increased by 2.8%,7% and 29.6% respectively(P<0.01);MAO decreased by 60%,69.8% and 80.5%,GSH-px increased by 465.3%,563.8% and 635% respectively(P<0.01).ConclusionCSF shows anti-oxidative and anti-fatigue properties and can be given as prophylactic/therapeutic supplements for increasing antioxidant enzyme activities and preventing lipid peroxidation during strenuous exercise.

OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.
