ABSTRACT:Objective To analyze the effects of antisurvivin oligonucleotide (Survivin ASODN)on IL-6/STAT3 signaling pathway and down-stream cancer genes of ovarian cancer SKOV3 cell line and to detect the changes of invasive ability of cell line in order to explore the role of Survivin ASODN in reducing metastasis and recurrence of ovarian cancer and its potential clinical value.Methods ASODN was transfected into SKOV3 cells by lipofectamineTM2000 in ASODN group,and lipofectamineTM 2000 was introduced in control group.The invasive ability in ASODN and control groups was detected by Transwell chamber.The expressions of interieukin-6 (IL-6 ), signal transducer and activator of transcription 3 (STAT3 ), Survivin, and vascular endothelial growth factor (VEGF)in ovarian cancer cell line at mRNA level were detected by Real-time PCR.The expressions of IL-6 , STAT3 ,signal transducer and activator of transcription 3 phosphorylation (p-STAT3 ),Survivin,and VEGF-A in ovarian cancer cell line at protein level were detected by Western blot.Results The expressions of IL-6,STAT3, Survivin,and VEGF in ovarian cancer cell line at mRNA level were significantly down-regulated in ASODN group (P<0 .0 5 ).IL-6 ,STAT 3 ,p-STAT 3 ,Survivin and VEGF-A protein levels in ovarian cancer cell line were significantly down-regulated in ASODN group (P<0.05).The invasive ability was significantly reduced by ASODN (P<0.01).Conclusion ASODN targeting Survivin could reduce the invasive ability of ovarian cancer cell line. The mechanism may be blocking IL-6/STAT3 signaling pathway and its down-stream cancer genes of ovarian cancer cell line.ASODN targeting Survivin may have clinical value in preventing and treating the metastasis and recurrence of ovarian cancer.

Objective To quantitatively analyze the fetal lung echo and right lung volume in the third trimester by real-time three-dimensional ultrasound (3-D US) and evaluate the feasibility of fetal lung maturity. Methods A total of 732 women with normal singleton pregnancies between 28 and 42 weeks of gestation underwent ultrasound examination. The 3-D US equipment with a 3.5-5MHz transabdominal transducer was used for the fetal biometric measurement. The echogenicity ratio between fetal lung and liver was compared. The fetal lung volume was calculated by the rotational multiplanar technique for volume measurement (VOCAL). Results The right fetal lung volume increased with the increase of gestational age with a linear positive correlation (r=0.884, P<0.01). After 34 weeks, the echogenicity ratio of fetal lung to liver was more than 1.1. Conclusion The echogenicity of lung/liver and fetal lung volume could be used as normal fetal predictable indicators for fetal lung maturity.

Objective To observe the changes of intedeukin (IL)-17 in patients with maintenance hemodialysis (MHD) and its relationship with anemia. Methods Twenty sera from normal people(normal group) and sixty-eight sera from patients with MHD were sampled. Patients with MHD were divided into 4 groups by haemoglobin (Hb) levels: severity anemia group (12 cases), midrange anemia group(18 cases),light anemia group(18 cases) and non-anemia group(20 cases). IL-6 and IL-17 levels were measured in all the sera with ELISA. Meantime, C-reactive protein (CRP),Hb, ferritin and iron saturation ratio was observed. Results CRP,IL-17 and IL-6 levels in MHD patients were much higher than those in normal group. IL-17 levels in severity and midrange anemia group were higher than those in light anemia group,and IL-17 was positively correlated to Hb. Conclusions IL-17,IL-6 and CRP in patients is higher than that in normal people,and the microinflammation status exists in MHD. IL-17 may play a role in pathogenesis of microinflammation in MHD patients with anemia.

Objective To compare the carriage of dematiaceous fungi in wild toads from both en-demic area and non-epidemic area of chromoblastomycosis.Methods A total of354and45wild toads(Bufo Chinese)were caught from two counties of Shandong Province,Zhangqiu county,an endemic area of chromoblastomycosis,and from Laiyang county,an area where the infection of dematiaceous fungi in humans has not been found,respectively.The toads were killed and the suspension of the internal organs were used to isolate dematiaceous fungi.Results Eleven species including162strains of dematiaceous fungi were iso-lated from151of354(42.7%)toads from the endemic area.The isolated strains consisted of49Phialopho-ra verrucosa,33Exsophiala,19Phialophora(nonpathogenic),19E.jenselmei,12Cladosporium carrionii,3suspected of C.carrionii,7Rhinocladiella sp.,5Fonsecaea pedrosoi,4C.trichoides,3E.spinifera,1C.mi-nourae,4unidentified.Only4nonpathogenic dematiaceous fungi were isolated from4of45(8.9%)toads obtained from non-epidemic area.Conclusions Varieties of pathogenic dematiaceous fungi,especially C.carrionii,are isolated from wild toads in endemic area of chromoblastomycosis,while none from non-endemic area.The results suggest that the colonization of pathogenic dematiaceous fungi in wild toads may be associa-ted with endemicity of chromoblastomycosis.
