[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.

[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 vs.>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.

OBJECTIVETo investigate the distribution patterns of neuron-specific enolase (NSE) and synaptophysin (SYN) during the development of human fetal stomach.
METHODSSixteen specimens of human fetal (gestational age 2 to 4 months) gastric tissues were examined with immunohistochemistry for detecting the distribution of NSE and SYN expressions in the gastric walls.
RESULTSDuring the second to fourth gestational months, NSE was strongly expressed in the nerve cells and nerve fibers of the myenteric nerve plexus of human fetal stomach. As the gestational age increased, the numbers of NSE positive cells and fibers increased gradually in the gastric submucosa, but NSE was negative in the gastric mucosa. At the second gestational month, SYN expression was negative in the mucosa but positive in the myenteric nerve plexus; during the third to fourth months, positive SYN expression was found in the mucosa, submucosa and myenteric nerve plexus of the embryonic gastric walls and its expression intensity increased with the gestational age.
CONCLUSIONSYN and NSE are both involved in the regulation of the nervous system in the gastric wall but their expressions and distributions follow different patterns during the development of human fetal stomach.
