ABSTRACT
Clinical data of a child with acromesomelic dysplasia Maroteaux type (AMDM) treated in the Department of Pediatrics, Tianjin Medical University General Hospital at November 2018 was retrospectively analyzed.The female child aged 3 years and 3 months old with 83 cm height (-3.84 SD) had clinical manifestations of disproportionate short stature, disproportionate shortening of forearms and forelegs, and stubby fingers and toes.Gene sequencing identified compound heterozygous mutations, c.1640T>A(p.Val547Asp)/c.682G>A(p.Gly228Ser), in the NPR2 gene, which have not been reported in the Human Gene Mutation Database.Their protein function was predicted harmful.The child was diagnosed as AMDM.During the follow-up until 4 years and 8 months old, the child was 90 cm tall (-4.35 SD), with a growth velocity of 4.9 cm/year.She was treated with recombinant human growth hormone (rhGH) treatment for 9 months and regularly followed up.The child was now 98.2 cm height (-3.07 SD) and she had a growth velocity of 10.9 cm/year.This case report enriched the gene mutation spectrum of AMDM.Treatment with rhGH can effectively improve the height of the child, but the long-term effect needs further follow-up and observation.
ABSTRACT
Objective To investigate the characteristics of plasma glucose, insulin secretion and changes of insulin resistance (IR) after a glucose load in obese children, and to predict islet β-cell function. Methods A total of 635 obese children were classified into normal glucose tolerance (NGT) group (n=483), impaired glucose regulation (IGR) group (n=112) and type 2 diabetes mellitus (DM) group (n=40) based on their glucose levels. Subjects were also divided into G1 group (23 kg/m2≤BMI<30 kg/m2, n=393) and G2 group (BMI≥30 kg/m2, n=242) based on their different BMI levels. Level of fast plasma glucose (FPG, 0.5 h-PG, 1 h-PG, 2 h-PG and 3 h-PG) and insulin (FINS, 0.5 h-INS, 1 h-INS, 2 h-INS and 3 h-INS) were measured 0 h, 0.5 h, 1 h, 2 h and 3 h after a glucose load. Insulin resistance index (HOMA-IR), whole body insulin sensitivity index (WBISI), function of pancreatic beta-cell (HOMA-β), first-phase insulin secretion index (ΔI30/ΔG30) and area under curve of insulin (AUCI) were calculated and compared between groups. Results The value of insulin at each time point was significantly higher in IGR group than that of NGT group. The values of insulin at 0.5 h, 1 h, and 2 h were significantly lower in DM group than those of IGR group, respectively (all P<0.05). Compared with NGT group, AUCI, HOMA-IR and HOMA-β increased, but WBISI and ΔI30/ΔG30 decreased in IGR group (all P<0.05). HOMA-IR increased but WBISI, HOMA-βandΔI30/ΔG30 decreased in DM group (all P<0.05). Compared with IGR group, AUCI, HOMA-βandΔI30/ΔG30 decreased in DM group (all P<0.05). Values of FINS, AUCI, HOMA-IR, 2h-PG and HOMA-βwere significantly higher in G2 group than those of G1 group, but WBISI decreased (all P<0.05). There were no significant differences in FPG and ΔI30/ΔG30 between these two groups. Conclusion From NGT, IGR to DM, the peak of insulin secretion is postponed, insulin resistance is getting heavier and the compensation of insulin secretion after a glucose load is increased first and then decreased.
ABSTRACT
Objective To investigate the possible association of circulating components of GH-IGFs-IGFBPs system with the GHR-exon 3 genotype in idiopathic short stature (ISS) children. Methods Genomic DNA was extracted and isolat-ed from peripheral leukocytes in 108 ISS children. GHR-exon 3 polymorphism was analyzed with multiplex poly-merase chain reactions (PCR) assay. According to the results of genotype, ISS children were divided into GHRfl group and GHRd 3 group. The height and weight were recorded in two groups. The body mass index (BMI) and BMI standard deviation score (SDS) were measured. The serum levels of insulin-like growth factor (IGF)-1, IGF-binding protein (IGFBP)-3, IGF-1 SDS and IGFBP3 SDS were calculated. GH stimulation test was used to measure the serum GH peak value. Fifty-five ISS chil-dren were treated with recombine human GH [0.15 IU/(kg·d)] for three months to analyse the association of IGF-1 response of GH treatment and genotypes. Results There were 63 GHRfl and 45 GHRd3 in 108 ISS children. There were no signifi-cant differences in BMI, IGF-1, IGFBP3, GH peak, IGF-1 SDS and IGFBP3 SDS between two groups (P>0.05). Multiple stepwise regression analysis showed that age, IGFBP3, lg (BMI) and lg (GH peak) were influencing factors of lgIGF-1 (P<0.05). In 55 ISS children treated with rhGH, there were 34 cases of GHRd3. The differences of △IGF-1 and △IGF-1 SDS were higher in GHRd3 group than those of GHRfl group (n=21). Conclusion The GH sensitivity may be a risk factor in ISS children, which may not be related with GHR polymorphism.

ABSTRACT
Objective To investigate the change of HO-1 expression in adipose tissue of obese young SD rats as well as its relationship with macrophage infiltration and polarization. Methods Three-week old SD rats (n=24) were randomly divided into 2 groups, routine diet group (NC) and high fat diet group (FC). After feeding 4 weeks, triglyceride (TG), high den?sity lipoprotein (HDL-C), fasting glucose and insulin were compared between these two groups and the insulin resistance in?dex was calculated. The gene expressions of HO-1, IL-6, IL-10 and MCP-1 were assessed by quantitative PCR. Infiltration and polarization of macrophages and M2 macrophages in the visceral adipose tissue were examined by immunohistochemis?try. Results The levels of FINS, FBG and HOMA-IR in rats of FC group were higher than those of rats in NC group after 4 weeks feeding (P0.05) in MOD value of F4/80 and CD206 between these two groups (P>0.05). Conclusion The infiltration of macrophage in visceral adipose tissue of obese young SD rats significantly increased while HO-1 expression was reactively increased. This insinuated that HO-1 might play an important role in anti-inflammatory mechanism through regulating polar?ization of macrophages.
ABSTRACT
Objective:To explore the correlation between Coronin-1 and non-Mtb induced autophagy in macrophages and its possible signal pathway.Methods: The pEGFP-C1-Coronin-1 plasmids encoding the over-expression of Coronin-1 and pGenesil-1-Coronin-1 plasmids encoding the siRNA of Coronin-1 gene were constructed and transfected into RAW264.7 respectively in order to obtain their stable transfected cell line ( RAW264.7-Cor.Plus and RAW264.7-Cor.Minus ).After the RAW264.7, RAW264.7-Cor.Plus and RAW264.7-Cor.Minus group cells were treated with complete medium, starvation, Rapamycin and Cyclosporine A respectively,the transcription level of Beclin-1 gene was detected by RT-PCR,and the protein expression level of Coronin-1 and Beclin-1 and the ratio of LC3BⅡ/LC3BⅠwas analyzed by Western blot.Results:The over-expression plasmids,the siRNA plasmids and their stable transfected cell lines which can over-express the Coronin-1 or inhibit its expression were successfully constructed.When the three groups cell treated with blank control,the ratio of LC3BⅡ/LC3BⅠwas found that:RAW264.7-Cor.Minus>RAW264.7>RAW264.7-Cor.Plus significantly,and the transcription level of Beclin-1 gene and its protein detected by RT-PCR and Western blot respectively showed the same trend with the ratio of LC3BⅡ/LC3BⅠ;When the three groups cell treated with starvation,the ratio of LC3BⅡ/LC3BⅠjust become the opposite of the first result significantly;When the RAW264.7 cells treated with Rapamycin, the expression of Coronin-1 was inhibited significantly.The ratio of LC3BⅡ/LC3BⅠin the RAW264.7-Cor.Plus group treated with Rapamycin and CsA respectively was higher than its corresponding control treatment group.Conclusion:There is a correlation between Coronin-1 and non-Mtb induced cell autophagy in macrophage.In the nutrition sufficient condition, Coronin-1 can inhibit autophagy;in the hungry condition,Coronin-1 can promote autophagy.The regulation of autophagy by Coronin-1 may be associated with mTOR and calcium signaling pathway.

ABSTRACT
Objective To investigate the association of eosinophils with glucose and lipid metabolism disorder in obese children. Methods A total of 180 subjects,102 boys and 78 girls,aged 7 to 14 years were enrolled in General Hospital,Tianjin Medical University. The subjects were divided into 3 quartiles according to eosinophil percentage. E1 (0 to<37% of eosinophils),E2(37% to<73% of eosinophils),and E3(73% to 100% of eosinophils). Forty-six chil-dren were selected as control group with matched age and sex (26 boys and 20 girls). The body weight,height,waist circumference,blood pressure,blood routine examination,fasting plasma glucose (FPG),fasting insulin (FINS),and blood lipid in 4 groups were measured. The values of glucose and lipid metabolism and the indexes of physical examina-tion were compared among each group. Results The values of eosinophil percentage,body mass index (BMI),trig-ly-ceride,total cholesterol, low-density lipoprotein cholesterol, FINS, FPG,homeostasis model assessment of insulin resistance(HOMA-IR) and waist circumference in E1,E2,E3 group were significantly higher than those in control group,and the value of high-density lipoprotein cholesterol was significantly lower than that in control group,and there were significant differences (all P<0. 05). The blood pressure was significantly higher in E1 groups than that in other 3 groups (all P<0. 05). The values of BMI and HOMA-IR in E1 group were higher than those of E3 group(all P<0. 05). Eosinophil percentage was positively correlated with FINS (r=0. 190,P=0. 01),and negatively correlated with BMI and HOMA-IR(r=-0. 259,-0. 190 respectively,all P<0. 05). Conclusions Obese children have emerged glucose and lipid metabolism disorders. Peripheral eosinophil percentage may be an early marker of insulin resistance.

ABSTRACT
Objective To study the relationship between the level of serum epithelial fatty acid binding protein (E-FABP) and cardiovascular disease in obese children. Methods Thirty children with metabolic syndrome (MS), 32 obesity children with no MS and 50 healthy children were recruited. Serum E-FABP and glucose/lipid metabolic indices were measured. Results Com-pared with the healthy children, levels of serum E-FABP in MS children were signiifcantly elevated (P=0.001). Compared with obesity children, levels of serum E-FABP of MS children were elevated, but the difference was not signiifcant (P>0.05). The cor-relations of E-FABP with waist to hip ratio, waist-to-height ratio, atherogenic index, fasting insulin, insulin resistance index were positive (P<0.05). According to the multivariate stepwise regression analysis, E-FABP was the independent risk of atherogenic index (P=0.018). Conclusions E-FABP plays a role in the development of atherosclerosis in obesity and MS.
ABSTRACT
Because of their physiological and anatomical immaturity, premature infants are prone to disorders of glucose metabolism. In the ifrst week after birth, infants have the greater risk of abnormal glucose metabolism. Compared with term infants, the glucose/insulin homeostasis of preterm infants is very different. This article reviewed the characteristics of glycometabolism in premature infant and the methods of glucose test.
