Objective To study the expressions of nicotinamide phosphoribosyl transferase (Nampt)in main energy metabolism organs (liver, pancreas, skeletal muscle, and kidney ) of the rats with type 2 diabetes mellitus (T2DM),and to explore the correlation between the expression and distribution of Nampt and the occurrence of diabetes.Methods The SD rat diabetes model was established by injecting with streptozotcin (STZ).The SD rats were randomly divided into diabetes group and control group. Immunohistochemical Envision staining assay was used to detect the distribution and protein expressions of Nampt in liver,pancreas,muscle,and kidney tissues of the rats,at the same time the blood glucose and serum insulin levels were also be detected. Results The blood glucose level of the rats in diabetes group was significantly higher than that in control group (P<0.01),and the fasting insulin level was lower than that in control group (P<0.01).The Nampt expression in the liver tissue of the rats in diabets group was significantly increased,which distributed near the hepatic sinus in diabetes rats,and the Nampt expression was also increased in skeletal muscle in which the whole cell was thick dying;the Nampt expression mainly distributed in the renal tubular epithelial cells. Compared with control group, the positive expression rates of Nampt in liver,skeletal muscle,and kidney tissues of the rats in diabets group were significantly increased (P<0.05 or P<0.01).There was nearly no Nampt expression in pancreas tissue of the rats in diabetes group and the Nampt expression level was significantly lower than that in control group (P<0.01). Conclusion The Nampt expressions are much different in main energy metabolic organs of the rats with diabetes.It is suggested that Nampt may be used as a specific indicative marker in the process of diabetes.

Objective To study the effects of benzyl propionate nandrolone (BPN ) on the nicotinamide phosphoribosyl transferase (Nampt), insulin receptor substeate-2 (IRS-2 )and pancreatic duodenal homeobox-1 (PDX-1)expressions, cell cycle changes as well as insulin secretion in pancreatic islet cell NIT-1 lines, and to explore the influence of BPN in the Nampte xpression in NIT-1 cells and insulin signaling molecules in high glucose oxidation stress.Methods The NIT-1 cells were cultured with different concentrations (5.6,11.1,16.7,and 27.6 mmol·L-1)of glucose,then they were treated with 10 mg·L-1 BPN for 48 h with no BPN treatment as corresponding control groups.The expression levels of Nampt,IRS-2,and PDX-1 were tested by Western blotting assay.The changes of cell cycle were determined by FCM and the cell insulin secretion levels were measured with radioimmunoassay.Results Compared with corresponding control groups,the expression levels of Nampt,IRS-2, and PDX-1 proteins in the NIT-1 cells in various BPM groups were increased (P<0.05 or P<0.01).The G0/G1 phase arrest was relieved (P<0.01)when the cells was cultured in low glucose (5.6 mmol·L-1 )condition,and the G2/M block was remitted significantly in high glucose (27.6 mmol·L-1 )condition (P<0.01),furthermore, the cell insulin secretion was promoted compared with control groups except 1 1.1 mmol· L-1 glucose group (P<0.01).Conclusion BPN can promote the expression levels of Nampt,ISR-2 and PDX-1 proteins in NIT-1 cells. There is close relationship between the Nampt expression in NIT-1 cells and insulin signaling pathway and BPN prevents the cells from insulin resistance.

Objective To study the effect of Smad4 gene on angiogenesis related factors in human gastric cancer cell line.Methods Recombinant eukaryotie expressing plasmid pcDNA3.1 (-)-Smad4 containing Smad4 gene and empty vector pcDNA3.1 (-) were introduced into human gastric cancer cell line MKN28 using lipofectam and selected by G418,respectively.Two cell lines were obtained as follows:Smad4+-MKN28 cell line which was MKN28 transfected with a stable hybrid containing Smad4 gene and Smad4--MKN28 cell line with empty plasmid as control.The transcription and expression of VEGF and TSP1 were investigated by RT-PCR and Western blot.Results The mRNA expression of TSP1 in Smad4+-MKN28 cells was higher (P＜0.05) than that in control cells,while VEGF was lower(P＜0.05).Western blot showed the consistent results as measurement by RT-PCR.Conclusion Smad4 restoration in gastric cancer cells reduced angiogenesis rates through down-regulation of angiogenesis activitor and up-regulation of angiogenesis inhibitor.

Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".

Objective To construct and screen siRNA targeting a proliferation-inducing ligand (APRIL) gene in a mouse colorectal cancer celline, CT-26. To investigate the effects to the cell growth and migrant capacity of CT-26 after knockdown APRIL gene, lay the foundation for molecular targeted therapy to colorectal cancer. Methods Four pairs of APRIL siRNA were designed and chemically synthesized. And disorder sequences were synthesized as a negative control. These sequences were transfected with LipofectAMINE 2000 into CT-26 cells, which high-expressed APRIL gene. The transfection efficency rate of 6-FAM labelled control siRNA was detected by fluorescence microscope. The inhibition effectiveness of APRIL mRNA and protein was analyzed by FQ-RT-PCR and Western blot, respectively. Cell proliferation activity was analyzed by cell counting kit-8, cell migration capacity was detected by the repair of cell damage, and MMP-2 together with TIMP-1, two important regulatory genes in cell metastasis, were measured by RT-PCR.Results The different kinds of APRIL siRNA effectively suppressed the level of APRIL mRNA and the protein expression in CT-26 (P ＜ 0.05 ). Cell proliferation and metastasis ability were repressed after APRIL siRNA transfection( P ＜ 0.05 ), compared with random siRNA control and nontransfected control. The mRNA levels of MMP-2 and TIMP-1 genes wre significantly altered among APRIL siRNA groups and two control groups ( P ＜ 0.05). Conclusion We have constructed and screened a kind of siRNA (APsi737) targeting APRIL gene in a mouse colorectal cancer cell line, CT-26. APRIL siRNA can effectively inhibit the cell growth and migration capacity, maybe be regulated by MMP-2 and TIMP-1.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.
