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

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 .

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 influence of Akt inhibitor MK2206 in the proliferation and apoptosis of tongue squamous cell carcinoma TCA-8113 cells,and to clarify the possible mechanism.Methods The tongue squamous carcinoma TCA-8113 cells at the logarithmic phase were randomly divided into control group and 1,5,25,125, 250 nmol·L-1 MK2206 groups.The inhibitory rate of proliferation of TCA-8113 cells was detected with MTT method,and the apoptotic rate of TCA-8113 cells was determined with flow cytometry(FCM),and the expressions of caspase-9,Bad,GSK-3β,p-Akt and T-Akt proteins in the TCA-8113 cells were detected with Western blotting method.Results The IC50 of tongue squamous cell carcinoma TCA-8113 cells after treated with MK2206 for 12, 24,and 36 h were (112.54±1.67),(79.67±2.01),and (33.33±1.98)nmol·L-1 .The FCM results showed that the apoptotic rates of TCA-8113 cells after treated with 1,5,25,125,and 250 nmol·L-1 MK2206 for 12 h were (14.2±0.74)%,(19.3±0.45)%,(35.1±0.45)%,(39.6±0.48)% and (52.1±0.19)%;there were significant differences compared with control group(P<0.01).The Western blotting method results showed that the expressions of p-Akt, Bad and GSK-3βwere decreased with the increasing of dose and time of MK2206;compared with theβ-actin in control group,the bands got darken;the expression level of caspase-9 was increased, compared with theβ-actin in control group, the bands got darken;the T-Akt protein expression did not change significantly;compared with the β-actin in control group, the color of bands had no significant difference.Conclusion Akt inhibitor MK2206 can inhibit the proliferation of tongue squamous cell carcinoma TCA-8113 cells and induce apoptosis.

Objective To construct and to identify eukaryotic expression vector expressing Islet-brain 1(IB1) gene.Methods Total RNA was extracted from human insulinoma.IB1 gene was amplified by PCR from human IB1cDNA library.The eukaryotic expression vector encoding IB1 was constructed by inserting the IB1 cDNA into EcoR I/Kpn I sites of the pEGFP-N1 vector with the green fluorescent.The construct was transfected into RINm5F cell line,screened by G418.The phase contrast fluorescence microscope,flow cytometer,and Western blot were used to identify the recombinant plasmid and transfeced cell line.Results The RT-PCR products for IB1(AA1-280)generated from human insulinoma was 840 bp.Sequence analysis proved the same sequence as published in Gen-Bank.Two bands showed that pEGFP-N1 vector encoding IB1 digested by EcoR I or Kpn I.Western blot showed IB1 gene was expressed in RINm5F cells.Conclusion The recombinant prokaryotic expression plasmid pEGFP-N1-IB1 has been successfully constructed.
