2.Clinical observation of sitagliptin combined with insulin aspart 30 with in the treatment of secondary failure of sulphonylurea in type 2 diabetes mellitus
Chinese Journal of Postgraduates of Medicine 2016;39(3):258-260
Objective To observe the effect of sitagliptin combined with insulin aspart 30 in the treatment of secondary failure of sulphonylurea in type 2 diabetes mellitus. Methods Fifty-six cases were divided into group A and group B in random block design, with 28 cases of each group. The patients in group A was treated with sitagliptin combined with insulin aspart 30, while the patients in group B was given subcutaneous injection of insulin aspart 30R. All patients were treated for 12 weeks. Fasting plasma glucose(FPG), 2-hour postprandial plasma glucose(2 hPG), glycosylated hemeglobin(HbA1c), insulin secretion index (HOMA-β), body mass index (BMI), and incidence of low blood glucose before and after treatment were compared. Results Compared with that in group B, FPG [(5.61 ± 1.14) mmol/L vs. (7.8 ± 1.22) mmol/L], 2 hPG [(7.62 ± 1.35) mmol/L vs(9.72 ± 1.41) mmol/L] and HbA1c [(7.11 ± 0.83)%vs.(8.32 ± 1.04)%] in group A had a significant decrease;HOMA-β[(50.31 ± 5.12) vs. (41.86 ± 4.53)] of group A was higher than that of group B (P

OBJECTIVETo investigate the impacts of biological factors (age and sex) and family factors (socioeconomic status and parenting style) on the early lexical and intellectual development of children in a longitudinal tracking study.
METHODSA total of 38 Mandarin-speaking children aged from 18 to 24 months were surveyed using the Putonghua Chinese Communicative Development Inventory (PCDI), the Ages and Stages Questionnaire (ASQ), and a self-designed Questionnaire for Parents. All of the subjects were retested using PCDI and ASQ after 6 months.
RESULTSBiological factors accounted for 65% of the variance in lexical development, 10% of which was attributed to gender, in the first survey. After six months, the contribution of age decreased to 26% and gender had no significant impact. Lexical development could positively predict the intellectual development of children. When age and gender were controlled, it accounted for 22% of the variance in intellectual development. Family socioeconomic factors had no significant impacts on lexical and intellectual development. Children's recognition of people and objects around them with guidance of parents in parenting styles could positively predict the intellectual development of children six months later, which accounted for 10% of the variance.
CONCLUSIONSBiological factors play an important role in the early lexical development of children. However, the influence decreases with the increase of age (months). Biological factors, lexical development, and parenting style have a combined influence on children's intellectual development.

Objective To explore the migration of transplanted neural stem cells labeled with SPIO with 4.7T MR system and study cell differentiation by immunohistochemistry in ischemic rats. Methods Rat neural stem cells(NSCs)co-labeled with SPIO mediated by poly-L-lysine and bromode- oxyuridine(BrdU)were transplanted into the middle cerebral artery occlusion(MCAO)rats after 14 days when MCAO model was made successfully.4.7T MR scanner was used to monitor the migration of transplanted cells after 1.2,3,4,5 and 6 weeks post-transplantation.After MRI examination at 6th week,the rats were killed and Prussian blue staining and immunohistochemistric staining were per- formed to study migration and functional differentiation of NSCs.Results Three weeks after trans- plantation,linear hypointensity area derived from migration of labeled NSCs was observed in the corpus callosum adjacent to the injection site.Six weeks after transplantation,linear hypointensity area was moved toward the midline along the corpus callosurn.MRI findings were confirmed by Prussian blue staining and immunohistochemical straining.Co-labeled immunohistochemical methods demonstrated transplanted NSCs could differentiated into astrocytes and neurons.Conclusion MRI is very useful in demonstrating the migration path of labeled NSCs.Transplanted NSCs into ischemic rats can differen- tiated into astrocytes and neurons during the process of migration.

Objective To investigate the application of the parenteral nutrition prescriptions for tumor patients in a tertiary hospital .Methods In this cross-sectional study , the parenteral nutrition prescriptions of all tumor inpatients in a tertiary hospital were collected from May to June in 2015 .The general data of patients who had used parenteral nutrition , the types of parenteral nutrition products , as well as the ratio of energy to ni-rogen ( E/N) , glucose/lipid ( G/L) ratio, non-protein energy to nitrogen ratio , and liquid volume were recor-ded and analyzed .Results Parenteral nutrition prescriptions were collected from 528 patients and showed high irrationality.The nutrient insufficiency rate was nearly 58.3%.The E/N (100:1 ~200:1) accounted for 32.3%and the G/L ( 1:1 ~2:1 ) 20.6%.Conclusions The rational application of parenteral nutrition should be a priority in clinical settings .A clinical nutrition supporting team may be established in tertiary hospi-tals to guide the appropriate use of parenteral nutrition .
