[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.

Objective:To investigate the early behavioral characteristics of children with autism within the age of 1.5 to 3 years in order to provide basis for early diagnosis and intervention. Methods: Using mass random sampling, 8006 children aged 1.5 to 3 years in nine districts in Tianjin were screened with a self-made questionnaire. Totally 432 children with suspected autism were diagnosed and rated according to the diagnosing criteria of DSM-Ⅳ and assessed with the Childhood Autism Rating Scale (CARS). Their behavioral characteristics were assessed with the Autism Behavior Checklist (ABC) and the early behaviors were compared between the children with autism and the normal children. Results: Children with autism in infants and suspicious positive group were different from normal children in 9 items such as" Abnormal language skills", "No index points the light", "No acts of posing as the game", "Could not normally play with toys, "and others(P <0.05). Children with autism in infants were different from suspicious positive group in 5 items such as"Children have no eye contact with others". The items with positive rate higher than 95% were interpersonal communicate barriers, mimic the functional deficiencies, language communicate barriers, non-verbal communication barriers and mental deficiency in CARS. The results of ABC showed that severe autism had much higher scores than mild to moderate autism both in the sense (S) and body function(B) areas [(8.00 ±3.30) vs. (5.15 ±2.58), (12.00 ±6.12) vs. (6.15 ±3.26); Ps <0.05]. Conclusion: The develop mental and behavioral symptoms can exist in early period of life of children with alltism, to which highly attention should be paid.

Objective:To understand the clinical features and risk factors of the first seizures in children with febrile seizures, to guide clinicians to take appropriate intervention measures for children with risk factors, and to reduce the incidence of febrile seizures.Methods:A total of 616 children with first-onset febrile seizures admitted in our hospital from August 2016 to August 2018 were enrolled in this study.The clinical characteristics and risk factors of first-onset seizures were retrospectively analyzed.And 601 children with fever but no seizures were randomly selected as the control group.Results:There were 616 children with febrile seizures, including 344 males and 272 females, 584 Hans and 32 Mongolian.A total of 126 cases (20.5%) were under 1 year old, 405 cases (65.8%) were 1-3 years old, and 85 cases(13.7%) were over 3 years old.The upper third of the episodes were acute upper respiratory tract infections[53.6%(330/616)], herpetic angina[25.9% (160/616)], and infant acute rash[10.5%(65/616)]. There were 570 cases(92.5%) with seizures at 38.0 ℃ and above, 16 cases(2.6%)had fever after seizures.A total of 534 cases(86.7%) had seizures within 24 hours of fever, and 608 cases(98.7%) presented with a generalized seizures.The duration of seizures was less than 5 min in 548 cases (89.0%), 5-14 min in 48 cases (7.8%), 15-29 min in 16 cases (2.6%) and more than 30 min in 4 cases (0.4%). Of the 572 patients (92.9%), only one seizure occurred in a single heat stroke.In the clinical type, simple febrile seizures accounted for 88.3%(544/616), complex febrile seizures accounted for 11.0%(68/616), and seizures persisted in 0.7%(4/616). Risk factors analysis showed that age, low sodium, low iron and low zinc, cesarean section, abnormal birth history, vaccine exposure history one week before convulsion, and family history of febrile seizures were statistically different between the febrile seizure group and the control group( P<0.05). Logistic regression analysis found that the age of first febrile seizures, low iron, cesarean section, low sodium and family history of febrile seizures were the independent risk factors for the first episode of febrile seizures ( P<0.05). Conclusion:The first episode of febrile seizures are more common in infants and young children under 3 years old.It is mainly caused by simple febrile seizures.The temperature of seizures is high and it is easy to occur within 24 hours after fever.Viral infection is the most common cause.The risk factors for the first episode of febrile seizures are episode age, low iron, cesarean section, low sodium and family history of febrile seizures.Taking appropriate interventions for risk factors can reduce the incidence of febrile seizures.

Radiotherapy uses high-energy X-rays or other particles to destroy cancer cells and medical practitioners have used this approach extensively for cancer treatment (Hachadorian et al., 2020). However, it is accompanied by risks because it seriously harms normal cells while killing cancer cells. The side effects can lower cancer patients' quality of life and are very unpredictable due to individual differences (Bentzen, 2006). Therefore, it is essential to assess a patient's body damage after radiotherapy to formulate an individualized recovery treatment plan. Exhaled volatile organic compounds (VOCs) can be changed by radiotherapy and thus used for medical diagnosis (Vaks et al., 2012). During treatment, high-energy X-rays can induce apoptosis; meanwhile, cell membranes are damaged due to lipid peroxidation, converting unsaturated fatty acids into volatile metabolites (Losada-Barreiro and Bravo-Díaz, 2017). At the same time, radiotherapy oxidizes water, resulting in reactive oxygen species (ROS) that can increase the epithelial permeability of pulmonary alveoli, enabling the respiratory system to exhale volatile metabolites (Davidovich et al., 2013; Popa et al., 2020). These exhaled VOCs can be used to monitor body damage caused by radiotherapy.
