Objective To investigate the implications of gene expression pattern of pancreatic endocrine differentiation from mouse embryonic stem cells (mES) in vitro.Methods Mouse ES cell line ES W9.5 was cultured and differentiated into pancreatic endoerine progenitor cells by using the stepwise differentiation strategy in vitro,then stage specific genes expression were tested by RT-PCR and immnunoeytochemistry.The Illumina Mouse Ref-8 vl.1 Expression BeadChips were used to compare the changes in the transcriptome of mES-derived differentiated cells on day4,8,15,20,22,25 after differentiation to undifferentiated mES cells.Results A total 86 differentially expressed genes,both up- and down-regulated,were found during the whole differentiation stage,6 gene clusters with the same developing patterns and differentially expressed genes in 6 groups were collected.By number,the most differentially expressed genes corresponded to posterior foregut stage( 201 genes) followed by definitive endoderm stage ( 17 genes).Conclusions The analysis of the genes with the same developing pattern and differentially expressed genes at each differentiation stage during pancreas development by microarray analysis provides some evidences of early embryonic and pancreatic development.

Objective To analyze the influencing factors of hemoglobin A1c in type 2 diabetic patients,including blood glucose,anti-diabetic therapeutic regiments,disease course,age,diabetic education,degree-educated,self-monitoring blood glucose.Methods Seventy-eight type 2 diabetic patients were divided into two groups by different degree of blood glucose,anti-diabetic therapeutic regiments,disease course,age,diabetic education,degree-educated,self-monitoring blood glucose.The levels of hemoglobin A1c in two groups were compared.Results There were significant changes in the levels of hemoglobin A1c between fasting blood glucose (FBG) ≤ 6.1 mmol/L group (30 cases) and FBG ＞ 6.1 mmol/L group (48cases),2 h postprandial blood glucose (2hBG) ≤8.0 mmol/L group (32 cases) and 2hBG ＞ 8.0 mmol/L group (46 cases ),insulin treatment group (27 cases) and no-insulin treatment group ( 51 cases ),combined drugs treatment group ( 36 cases ) and single drug treatment group ( 15 cases),age ≤ 65 years old group (41cases) and age ＞65 years old group (37 cases),disease course≤ 10 years group (39 cases) and disease course ＞ 10 years group( 39 cases),degree-educated above high grade group( 34 cases) and degree-educated below high grade group (44 cases),diabetic education ≥2 times/month group (20 cases) and diabetic education ＜ 2 times/month group (58 cases),self-monitoring blood glucose≥2 times/week group ( 19 cases)and self-monitoring blood glucose ＜ 2 times/week group (59 cases)[ (6.7 ± 1.5 )％ vs.(7.9 ± 1.3 )％,(6.8 ±1.1)％ vs.(7.8 ± 1.2)％,(6.7 ± 1.5)％ vs.(8.1 ± 1.4)％,(6.8 ± l.0)％vs.(8.0 ± 1.6)％,(6.9 ± 1.7)％ vs.(7.4 ± 1.6)％,(6.5 ± 1.2)％ vs.(8.2 ± 1.3)％,(6.9 ± 1.0)％ vs.(7.6 ± 1.4)％,(6.1 ± 1.7)％ vs.(8.0 ±1.1 ) ％,(6.7 ± 1.1 )％ vs.(7.6 ± 1.2)％ ] (P ＜ 0.01 or ＜ 0.05 ).Conclusion Blood glucose,anti-diabetic therapeutic regiments,disease course,diabetic,degree-educated,self-monitoring blood glucose are the important factors influencing hemoglobin A1c.

Objective To investigate the endovascular treatment of peripheral vascular anomaly in children and its efficacy.Methods Eighty-three children with peripheral vascular anomaly were treated via endovascular means. Before and during the endovascular operation,all the cases were diagnosed as follows: arteriovenous fistula in 23 cases, cirsoid angioma 32 and cavernous hemangioma 28. The endovascular approaches included:①transcatheter embolization using coils or gelfoam sponge;② transcatheter embolization combined with local cirrhosis agents treatment.Results Immediate angiography after embolization showed all the arteriovenous fistulas and hemangiomas were efficiently occluded and the clinical presentation and symptoms improved greatly. Follow-up one to three years after operation demonstrated 100% of efficacy and 68.7% curative rate with no complications. Conclusions Endovascular approach for peripheral vascular anomaly in children is a micro-invasive, safe and effective way.

Objective:Study the relationship of HLA I and B7 1 to elucidate the role of costimulatory molecule on antigen presentation in immunological rejection.Methods:FCM was applied to detect the expression of B7 1 Then the cytotoxicity of PBML was observed before and after blocking the HLA I Results:The level of HLA I expression increased greatly(P

Clinical features of 2 cases of ectopic ACTH syndrome with manifestation of severe hypercortisonism are described with the aim of exploring effective therapies.

The leucoanthocyantin reducase (LAR) gene, an important functional gene of catechins biosynthesis pathway, was cloned from Fagopyrum dibotrys (D.Don) Hara by degenerate PCR and rapid amplification of cDNA ends (RACE). The full-length cDNA of FdLAR is 1 581 bp (GenBank accession: JN793953), containing a 1 176 bp ORF encoding a 391 amino acids protein, and its 3'-untranslated region has an obvious polyadenylation signal. The recombinant plasmid containing FdLAR completed ORF was transformed into E. coli BL21 (DE3). The target fusion peptide with molecular weight of 66 kD was expressed under the condition of 16 degrees C and induced by IPTG at final concentration of 1.0 mmol x L(-1). Bioinformation analysis indicated that the amino acid sequence of FdLAR showed great homology to other LAR with the NADB-Rossmann conversed domain in the N-terminus. Real-time quantitative PCR was used to detect the expression levels of FdLAR gene during different development periods. The determination of flavonoids contents in appropriate rhizomes showed that the relationship between FdLAR gene expression and the accumulation of flavonoids displayed different trends during vegetative growth and reproductive growth stages, suggesting that the FdLAR gene may be involved in the pathway of flavonoid metabolisms in Fagopyrum dibotrys.

Survivin gene is the strongest inhibitor of apoptosis so far.Recently,it was found that the promoter polymorphism of survivin gene is closely related to risk of cancer and genetic susceptibility.This finding might provide clues for further elucidation of the correlation of risk of cancer and genetic polymorphism,and for diagnosis,prevention and screening of cancer gene.

MicroRNAs (miRNAs) regulate target genes expression in the post-transcriptional levels.There are many kinds of differential expressions of miRNA in head and neck cancer,and the miRNA participate in a series of important biological processes such as cell development,proliferation,differentiation,apoptosis and etc.miRNAs is expected to become an effective means for the diagnosis and treatment of head and neck cancer.
