Objective To observe the clinical effectiveness of alprostadil combined to pancreatic kininogenas in the treatment of gerontal diabetic peripheral neuropathy.Methods Totally 90 gerontal patients with diabetic peripheral neuropathy were randomly divided into three groups,the first group received the treatment of mecobalamin,the second group received mecobalamin plus pancreatic kininogenas,the last group received mecobalamin,alprostadil and pancreatic kininogenas (30 cases for each).The course of treatment was 4 weeks,the nerve conduction and effective rate of 3 groups were compared after treatment.Results Compared with the first group(53.3%),the total effective rate was significantly improved in the second group (80.0%)and the third group(100.0%) (P<0.05).After treatment,the therapeutic effect of every group was boosted,and the second group was better than the first group,and the last group was best(P<0.05).Conclusions Alprostadil combined to pancreatic kininogenas is effective and safe for the treatment of elderly diabetic peripheral neuropathy.

Objective To assess the association of obesity, serum lipid levels and insulin resistance with leptin in Nanjing population. Methods One hundred and eighty eight subjects aged 22~81 years in Nanjing were divided into three groups according to BMI and dignosis criteria of diabetes: normal group, obese group and diabetes group. Their weight, height, waist, abdomen and hip circumferences were measured. Total cholesterol, triglycerides, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apoA, apoB, fasting plasma glucose (FPG), true insulin (TI), immunoreactive insulin (IRI) and leptin were also measured. ISI 1=1/(FPG?TI) and ISI 2=1/(FPG?IRI) as insulin sensitivity indexes were used to analyse the relation between leptin and insulin resistance. Results Fasting serum leptin level was associated with sex (four fold as high in women as that in men). BMI was the second strongest determinant of leptin. Leptin was positively correlated with TI (r=0.32, P

Objective To explore the effect of microRNAs 224 and 21 on human glioma stem cells survival and the possible molecular mechanisms.Methods qPCR was used to detect the dysregulated expression of microRNAs in malignant glioma samples, human GBM stem cells, artificially established GBM stem cell lines and human tissues.Caspase 3/7 assay, Annexin V apoptosis/fluorescence assay were performed to determine the effect of miR-21 or miR-224 mimics and inhibitor on cell apoptosis.Living cells count was used to assess miR-21 or miR-224 mimics and inhibitor on cell growth.TargetScan was used to explore potential targets of miR-21 and miR-224, and dual luciferase reporter assay was used to identify whether the 3’UTR of Caspase 3, Caspase 9 and Bim mRNA was a binding target of miR-21 or miR-224.Western blot was used to detect the expression of Caspase 3, Caspase 9 and Bim protein after transfection of miR-21 or miR-224 mimics or inhibitors.Results miR-21 and miR-224 are strongly upregulated in GSC samples, multiple GBM human tumor specimens, and GBM neurosphere stem cell lines ( P<0.05 ) .Caspase 3/7 assay and Annexin V apoptosis/fluorescence assay results showed that miR-224 and miR-21 regulated GSC apoptosis.Living cells count results demonstrated that miR-224 and miR-21 regulated GSC growth.miR-224 and miR-21 regulate pro-apoptotic gene expression by directly targeting Caspase 3, Caspase 9, and Bim 3’-UTRs. Conclusion These results indicate that miR-224 and miR-21 are important physiologic drivers of GSC resistance to apoptosis, providing new points of therapeutic leverage against these treatment-resistant cells.

Objective To investigate the relationship between interleukin-18(IL-18)and the pathogenesis of type 2 diabetes melli-tus.Methods 72 healthy Sprague-Dawlay male rats were randomly divided into four groups, NC group,NCS group,HF group and HFS group.At the end of the 8th week,NCS group and HFS group were injected with STZ(25mg/kg)into abdominal cavity.At the end of the 10th week,diabetic rats were screened by oral glucose tolerance test(OGTT).The blood sample was collected when the rats were killed at the end of the 14th and 20th week.The levels of serum IL-18,IL-6 and tumor necrosis factor-α(TNF-α)were assayed with ELISA.Results Most rats in HFS group were achieved the diagnostic standard of diabetic rat, and their insulin sensitivity index(ISI)were decreased.At the end of the 14th week and 20th week,the levels of serum IL-18,IL-6 and TNF-α in HFS group were significantly higher than those in NC group(P<0.01).In HFS group,the levels of serum IL-18,IL-6 and TNF-α at the end of the 20th week were higher than those at the end of the 14th week,but it had no statistic significance(P>0.05).Pearson linear correlation analysis showed that the level of serum IL-18 in HFS group was positive correlated with FBG,IL-6,and TNF-α(r=0.90,P<0.01 or r≥0.73,P<0.05),and negative correlated with ISI(r=-0.86,P<0.01).Condusions Our results show that IL-18 is related with the pathogenesis of type 2 diabetes mellitus and chronic inflammation plays an important role in the development of type 2 diabetos mellitus.

AIM:To explore a novel method to isolate human nucleus pulposus mesenchymal stem cells (hNP-MSCs) in vitro and to identify their biological characteristics.METHODS:The explant culture method was employed to isolate hNP-MSCs from nucleus pulposus tissue obtained by percutaneous endoscopic lumbar discectomy (PELD).The isolated cells were passaged for purification and cultured in vitro followed by morphological observation.The cell proliferation ability was detected by CCK-8 assay.Growth curves of the cells were drawn and surface antigens were detected by flow cytometry.The cells at the 3rd~6th passages were induced for adipogenic, osteogenic and chondrogenic differentiation, and examined by oil red O staining, alizarin red staining and Alcian blue staining.RESULTS:The cells with self-renewal were obtained from nucleus pulposus tissue obtained by PELD.The results of flow cytometry analysis revealed that the cells were positive for CD29, CD44, CD90, CD73 and CD105, but negative for CD34 and CD45.The proliferative capacity was consistent with the growth characteristics of MSCs and multilineage differentiation potential was identified.CONCLUSION:A novel method to efficiently isolate and culture hNP-MSCs,PELD combined with explant culture method,was established, which would promote the study of regenerative medicine based on hNP-MSCs.

AIM: To establish hybrid mouse embryonic stem (ES) cell line from blastocysts of the (C57BL/6J × 129/J) F1 mouse. METHODS: 3.5 days post- coitus (d.p.c.) blastocysts were cultured on mouse embryonic fibroblasts (MEFs) in the medium, after 3 - 4 days, Inner cell mass were picked up and disaggregated, then reseeded. After the ES - like colonies appeared, passaged them to give permanent ES cell lines. The pluripotent propertes of ES cells obtained were analyzed by alkaline phosphatase (AKP) activity, expression of SSEA- 1 and Oct-4, and their capacity to form teratoma. RESULTS: Two hybrid ES cell lines, SC1001, SC1002 were obtained from blastocysts of the (C57BL/6J × 129/J) F1 genotype. Most of these ES cells had a normal karyotype and an XY sex chromosome composition. The pluripotent properties of the cell lines were analyzed on the basis of their alkaline phosphatase activity, expression of SSEA - 1 and Oct - 4, and their capacity to form teratoma in severe combined immunodeficiency (SCID) mice. CONCLUSION: Two hybrid mouse ES cell lines having pluripotent properties and capacity for long - term self renewal were generated from blastocysts of the ( C57BL/6J × 129/J) F1 genotype.

Background and Objectives:
Mesenchymal stromal cells (MSCs)-based treatment for degeneration of intervertebral disc (IVD) has been proposed recently. We here addressed whether MSC secreted factors can rejuvenate nucleus pulposus- derived stem/progenitor cells from degenerated disc (D-NPSCs) in vitro.
Methods:
and Results: We analyzed the expression of MSCs and NP cell specific surface markers, pluripotency related genes, multilineage potential and cell proliferative capacity of D-NPSCs upon incubation with the conditioned medium which was collected from the umbilical cord derived MSCs (UCMSCs). Our results indicated that the conditioned medium restore the stemness of D-NPSCs by up-regulating the expression level of CD29 and CD105, pluripotency related genes OCT4 and Nanog, and NP progenitor marker Tie2. The increased stemness was accompanied by promoted cell proliferative capacity and improved osteogenic and chondrogenic differentiation potential.
Conclusions
Our findings suggested that the UCMSCs derived conditioned medium might be used to rejuvenate the degenerated NP stem/progenitor cells.
