Objective To compare the therapeutic efficacy of two different administration routes of insulin administra?tion on juvenile type 1 diabetes mellitus (T1DM) complicated with diabetic ketoacidosis(DKA). Methods A total of 223 cases of juvenile T1DM was included in this study, among which 98 were complicated with DKA. Insulin was delivered through either continuous subcutaneous insulin infusion(CSII) by insulin pump or via multiple subcutaneous insulin injec?tion (MSII). Recovery period of blood glucose, insulin doses that were adminstrated, the urinary ketone bodies clearance time, the recovering time from DKA and the frequency of hypoglycemia incidence were all compared between these two routes. Results Both CSII and MSII routes reversed blood glucose and DKA effectively. However the recovering time of blood glucose and DKA, insulin dosage,the urinary ketone bodies clearance time and the frequency of hypoglycemia inci?dence all improved better or quicker in CSII than in MSII. Conclusion CSII by insulin pump is safer and more effective than MSII in the treatment of junvenile T1DM with metabolic disturbance and diabetic ketoacidosis.

Objective To investigate metformin combined with insulin aspart 30 injection (NovoMix 30) in the treatment of type 1 diabetes mellitus (T1DM) in children and adolescents. Methods A total of 126 T1DM children over 10 years of age were randomly divided into insulin group (A) and insulin + metformin group (B). A group (n=60) was given insulin aspart 30 injection (insulin aspart 30), and B group (n=66) was given the metformin and insulin aspart 30 injection (NovoMix 30). Results The two groups can effectively control blood glucose, but the B group in the blood glucose control time, insulin dosage, the incidence of hypoglycemia, fasting blood glucose and hospitalization time were better than those of A group. There was no significant difference in liver and kidney function before and after oral administration of metformin in B group (P>0.05). Conclusion Metformin combined with insulin is effective and safe in the treatment of children with T1DM.

Plant expression cassette for TaDREB from wheat was constructed into plasmid pBIR1.Aloe stems were used as explants for the transformation mediated by Agrobaterium.Infected tissues were selected using G418 to generate transformants.In total,58 resistant plantlets to the antibiotics were obtained from the infected explants.The designed primers according to the selective gene npt II and the target gene TaDREB were used to analyze all of the G418 resistant plantlets.PCR results demonstrated that TaDREB were successful transferred into aloe genomic with the transformation efficiency of 0.5%.The transgenic aloe plants were treated under 4℃ for two weeks and then at-20℃ for 30min.The treatment showed that the leaves of negative plants appeared severe evidence of freeze injury with brown,withered and translucent,while the positive plants appeared good growing condition.The activities of enzymes such as peroxidase(POD)and superoxide dismutase(SOD)of transgenic plants which were stressed for 14 days under low temperature were analyzed.The results indicated that the trend of SOD and POD activities in transgenic plants was down-up-up-up,and that in non-transgenic plants was down-up-down-down.The average value of relative electrical conductivity in the positive plants was 0.456 which was lower than 0.685 in the negative plants.It is supposed that transformation of the kind of gene could improve the resistant ability of aloe to low temperature.
