ABSTRACT
[Objective]Dysregulated long noncoding RNAs(lncRNAs)have been found involved in human diseases,including cancers. Long non-coding RNA growth arrest-specific 5(GAS5)was reported to be dysregulated in different types of cancers. Howev-er,the role of GAS5 in ovarian cancer remains elusive.[Methods]In the present study,the expression of GAS5 was detected in 108 ovarian cancer tissues and compared adjacent normal tissues by quantitative real-time PCR(qRT-PCR).[Results]The results showed that the expression levels of lncRNA GAS5 were significantly decreased in cancer tissues(P=0.0004),and it was negatively correlated with tumor size(5 cm,P<0.0001),invasion depth(T1-T2 vs. T3-T4,P=0.0021),and tumor grade(Ⅰ~Ⅱgrades vsⅢ~Ⅳgrades,P=0.0086)in ovarian cancer patients. Kaplan-Meier analysis demonstrated that decreased lncRNA GAS5 expression contributed to poor disease-free survival and overall survival.[Conclusion]In conclusion ,our study suggested that decreased lncRNA GAS5 expression may beidentified as a potential poor prognostic biomarker in ovarian cancer.
ABSTRACT
[Objective] To investigate the relationship of different types of gestational diabetes mellitus (GDM) and thyroid function.[Methods] A Total of 3846 cases,which received prenatal examination,delivered in the Eastern Hospital of the First Affiliated Hospital,Sun Yat-sen University and performed a 75 g oral glucose tolerance test (75 g 0GTT) at 24-28 gestational weeks,from Jan 1st,2014 to Dec 31st,2015,were divided into 2 groups.Normal blood glucose group:the result of OGTT (fasting plasma glucose,1 hour glucose and 2 hour glucose) was normal;Gestational diabetes mellitus group (GDM group):the result of 0GTT was abnormal.GDM group were divided into Ⅰ,Ⅱ,and lⅢ.GDM Ⅰ defined as one abnormal blood glucose of result.GDM Ⅱ:two abnormal blood glucose.GDM Ⅲ:three abnormal blood glucose.1868 cases of healthy pregnant women were reselected as the control group.TSH,FT4 and TPO Ab were detected in two groups.Analysis of Variance,Mann-Whitney U test,Kruskal Wallis rank test or Fisher's test was used for statistical analysis.[Result] There were statistically significant difference in TSH,FT4 between GDM subgroup and control group (P =0.012,P =0.002).TSH median trend to increase in GDM Ⅱ,and FT4 median trend to decrease in GDM Ⅱ.The Prevalence of hypothyroidism in GDM Ⅱ and GDM Ⅲ were higher than those in control group.[Conclusion] The GDM group with two or three abnormal blood glucose had a higher incidence thyroid gland dysfunction,especial with subclinical hypothyroidism.We should fully test the thyroid function,treat diabetes as early as possible and improve the pregnancy outcome as we could.
