Objective Hyperglycemic clamp technique (HGCT) was performed to evaluate the effect of short-term intensive insulin therapy on the first and second-phase (1PH and 2PH) insulin secretion and maximum insulin secretion (MIS) in newly diagnosed type 2 diabetics. Methods Twelve volunteers with normal glucose tolerance (NC group) and six newly diagnosed type 2 diabetics (DM group) were included and HGCT was performed to assess the function of pancreatic islet beta cell. Then HGCT was repeated in the 6 patients following two week intensive insulin therapy. Results The levels of secreted insulin in 1PH, 2PH and MIS were 257?36 mU/L, 63?5 mU/L and 80?5 mU/L in NC group respectively, and 95?19 mU/L, 34?9 mU/L and 39?12 mU/L in DM group respectively. 1PH insulin secretion was significantly improved in the diabetics following 2 week treatment compared with that before the treatment (135?27 mU/L vs 95?19 mU/L, P=0.01). The insulin secretions in 2PH and MIS were slightly increased (40?9 mU/L vs 34?9 mU/L, P=0.09, 46?11 mU/L vs 39?12 mU/L,P=0.08, respectively). Conclusions Short-term intensive insulin therapy can improve the insulin secretions significantly in 1PH and slightly in 2PH and MIS in newly diagnosed type 2 diabetics.

The microbiota of the human gastrointestinal tract inhabits a complex ecosystem.Intestinal normal flora is obtained by newborn after birth,and suffers influences on the type of delivery,the type of feeding and contamination from the environment.There is emerging evidence indicating that quantitative and qualitative changes on gut microbiota contribute to alterations in the mucosal activation of immune system leading to intra-or extra-intestinal diseases.A balance between pathogenic and beneficial microbiota throughout childhood is important to gastrointestinal health,including protection against pathogens,inhibition of pathogens,nutrient processing,and regulation of host fat storage.Probiotics can promote an intentional modulation of intestinal microbiota favoring the health of the host.This paper is a review about modulation of intestinal microbiota on prevention and adjuvant treatment of intra-and extra intestinal pediatric diseases.

Objective To explore the alternations of CD4 + T cell subsets and their cytokines and transcription factors in children with Henoch - Schonlein purpura(HSP). Methods Forty - one children were enrolled in this stud-y,including 41 in acute stage of HSP,35 cases of HSP in clinical remission stage and 30 healthy children as healthy control group. The percentages of helper T lymphocytes(Th)1,Th2,regulatory T cells(Treg)and Th17 subsets were determined by flow cytometry(FCM). The concentrations of plasma interferon - γ( INF - γ),interleukin( IL) - 4, transforming growth factor - β1(TGF - β1 )and IL - 17 were examined by ways of enzyme - linked immunosorbent assay(ELISA). The expressions of T - bet,GATA3,Foxp3 and ROR - γt mRNA in peripheral blood mononuclear cells were examined by means of reverse transcription - polymerase chain reaction(RT - PCR). Results (1)During the a-cute and recovery stage of HSP,compared with the control group,the percentages of Th2 and Th17 cell subsets,the le-vels of plasma IL - 4 and IL - 17,and the expressions of GATA3 and ROR - γt mRNA were significantly higher(all P ﹤ 0. 05). The percentages of Th1 and Treg cell subsets,the levels of plasma INF - γ and TGF - β1 and the expres-sions of T - bet and Foxp3 mRNA were lower(all P ﹤ 0. 05). The imbalances of Th1 / Th2 and Treg/ Th17 appeared during the acute stage of HSP.(2)During the recovery stage of HSP,the percentages of Th1,Th2,Th17 and Treg,and the ratio of Treg / Th17 were of no difference compared with those in acute stage( all P ﹥ 0. 05). The ratio of Th1 / Th2,and the expressions of T - bet and Foxp3 mRNA were increased(all P ﹤ 0. 05),while the levels of plasma IL - 4 and IL - 17,the expressions of GATA3 and ROR - γt mRNA were decreased(all P ﹤ 0. 05)compared with those in acute stage. In the recovery stage of HSP,the imbalances of Th1 / Th2 and Treg/ Th17 were still obvious .(3)There was a positive correlation in every 2 cytokines of Th1,INF - γ and T - bet. And the same correlation existed in Th2, IL - 4 and GATA3,in Treg,TGF - β1 and Foxp3,and in Th17,IL - 17 and ROR - γt(P ﹤ 0. 05). Conclusions The imbalance of Th1 / Th2 and Treg/ Th17 is critical in pathological mechanism of HSP. The disturbance of immune tole-rance induced by Treg cells is important in HSP.
