The Protective Effects of Adenovirus-mediated IL-10 Gene and Anti-CD20 Monoclonal Antibody on the Pancreatic β Cells of NOD Mice in the Early Stage of Natural T1D Onset

Li Tang , Li Cheng , Fan Lei , Tian Fei , Tang Aiping

Background: Type 1 diabetes (T1D) is an autoimmune disease (AID) whose primary features include progressive pancreatic β cell damage and absolute insufficient endogenous insulin secretion. Recent studies have shown that a Th1/Th2 cell subset unbalance and excessively activated B lymphocytes are important pathogenic mechanisms.Objective and hypotheses: To investigate the protective effects of Adenovirus-mediated IL-10 gene and anti-CD20 monoclonal an...

Protective Effects of Combined Intervention with Adenovirus Vector Mediated IL-10 and IGF1 Genes on Endogenous Islet β Cells in Nonobese Diabetes Mice with Onset of Type 1 Diabetes Mellitus

Li Tang

Introduction: To investigate the protective effects of combined intervention with adenovirus vector mediated interleukin 10 (IL-10) and insulin-like growth factor 1 (IGF1) genes on islet β cells in nonobese diabetes (NOD) mice with type 1 diabetes mellitus (T1D) at early stage.Methods: Twenty-four female NOD mice at onset of diabetes and aged 17–20 weeks old were randomly divided into four groups. Mouse 1, 2 and 3 groups were intraperitoneally ...

Clinical characteristics and genetic expansion of 46, XY disorders of sex development children in a Chinese prospective study

Tang Yijun

Disorders of sex development (DSD) refer to a group of congenital diseases with inconsistencies between chromosomal karyotypes, external genitalia, and gonadal development. Diagnosis and management strategy of DSD is difficult and various due to heterogeneous phenotype and genotype. Under widespread use of genomic sequencing technologies, multiple genes and mechanism has been identified and proposed as genetic causes of 46, XY DSD. In this study, 178 46, XY DSD patients were e...

Insight of Differential Diagnosis of DAX-1 from Two Patients with Elevated Testosterone in Early Infancy

Li Tang , Ge Juan

DAX-1 is Dosage-sensitive sex reversal - Adrenal hypoplasia congenita critical region on the X chromosome 1, caused by mutation of NR0B1. It commonly presents X-Linked adrenal hypoplasia congenital, hypogonadotropic hypogonadism and infertility. However, we observed two patients whose testosterone elevated in their early infancy. Both of them are males with uneventful gestation and birth, and have a primary symptom as jaundice. For patient 1, poor feeding and pigment genital a...

The Role of IGF1R Gene Mutation in the Development of Oligodendrocytes

Yang Fan , Tang Mei , Li Hedong

Background: IGF1R gene mutation usually cause IUGR. The children born with IUGR were prone to some kinds of brain function disorders.Objective and hypotheses: The dysfunction of the brain was caused by the abnormal oligodendrocyte development.To establish lentivirus vector of IGF1R gene mutation (R709Q) and transfect oligodendrocyte precursors (Ge6). Observe the IRS/MAPK and PI3K/Akt/PKB signaling pathway and the change of proliferation, differentiation,...

Incidence of Newly Diagnosed Childhood Diabetes and Severity at Onset Between Pre-Pandemic and Pandemic COVID-19 Eras in Northern Thailand

Sinthuprasith Pattharaporn , Wejaphikul Karn , Puttawong Dolrutai , Tang-Ngam Hataitip , Sanrattana Naphatsorn , Unachak Kevalee , Dejkhamron Prapai

Background: The incidence rate (IR) of childhood diabetes is increasing globally. These upward trends were also found in Thailand. However, newly diagnosed childhood diabetes incidences are not updated, especially in Northern Thailand. There are possibilities that COVID-19 pandemic affects the development of acute diabetes after infection and the severity of the first clinical presentation of childhood diabetes. However, data are also conflicting regarding the...

Quantitative analysis of endogenous and exogenous steroid hormones is an important step for our understanding of the causes of endocrine disorders in pediatric. In this study, we developed a method to simultaneously quantify endogenous and exogenous steroids in pediatric urine and plasma. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to simultaneously quantify steroid hormones in children plasma and urine. Under the optimum conditions, th...

Gut microbiota, a potential cause of higher insulin sensitivity in children with Prader-Willi syndrome

Zhong Mian-Ling , Cai Yu-Qing , Tang Yan-Fei , Dai Yang-Li , Jiang Yong-Hui , Ni Yan , Zou Chao-Chun

Keywords: Prader-Willi syndrome; Gut microbiota; Insulin sensitivity; Metagenomics sequencing; Obesity.Aim: Obesity is the main driving factor for comorbidities in Prader-Willi syndrome (PWS) patients due to overeating behaviors. The gut microbiota has been implicated in the aetiology of obesity and associated comorbidities. The purpose of the present study is to characterize the fecal microbiota in Chinese patients with...
