Objective To investigate the relationship between β3 - adrenergic receptor(β3 - AR)gene poly-morphism and the susceptibility of occurrence in children obesity. Methods The database of PubMed,Web of Science,Springer Link,Medlink,SinoMed,Wanfang,VIP and CNKI were systematically browsed online. The study re-ports regarding β3 - AR associated with children obesity from January 1995 to February 2014 were included in the re-search. The data were extracted,evaluated and heterogeneity tested by using software RevMan 5. 1. Results A total of 162 related literature were retrieved,and 9 of them were eligible with 1 494 obese children and 1 623 normal children were included. Allele T compared with C,the differences between the study group and the control group were statistical-ly significant(P < 0. 05),the findings from the same TC + CC compared to TT and TC compared with TT + CC were similar. Japanese research findings were similar to those of China,but the differences between the study group and the control group had no statistical significance(P ﹥ 0. 05)in Hungary. The sensitivity analysis in each study was stable and the funnel graphics were basically symmetric. The results of sensitivity analysis and publication bias diagnostics demonstrated the reliability and stability of the Meta analysis. Conclusions TC + CC/ TT,TC/ TT + CC genotype and allele T/ C are related to the occurrence of childhood obesity in China,Japan,but there is no significant correlation with childhood obesity in Hungary. There are regional difference between β3 - AR gene polymorphism and genetic susceptibility to children obesity.

BACKGROUND:Adipose stem cells can differentiate into bone cells, cartilage cells, smooth muscle cells, myocardial cells and nerve cells. Adipose-derived stem cells and mesenchymal stem cells have very similar biological properties, and they are also very close in terms of cellsurface marker expression profile. OBJECTIVE:To investigate the expression of human leukocyte antigen II in adipose-derived stem cells and its immunogenicity and immunomodulatory effect, and to explore the specific mechanism. METHODS:After isolation and culture, the adipose-derived stem cells were stimulated with interferon-γ, and the expression of human leukocyte antigen II was detected by flow cytometry, the expression of indoleamine 2,3-dioxygenase was determined by real-time PCR and western blot. Adipose-derived stem cells were used to stimulate lymphocytes, and the cellproliferation was observed. The lymphocytes were stimulated with phytohemagglutinin, and then 1×102-1×105 adipose-derived stem cells were added to inhibit the proliferation;meanwhile, adipose-derived stem cells, a third party, at a dose of 1×102-1×105 were added to the ongoing two-way mixed lymphocyte reaction, and the cellnumber was calculated as count per minute. RESULTS AND CONCLUSION:The expression of human leukocyte antigen II and indoleamine 2,3-dioxygenase was low in adipose-derived stem cells, but up-regulated with stimulation of interferon-γ. Adipose-derived stem cells could not stimulate lymphocyte proliferation, but could inhibit lymphocyte proliferation induced by phytohemagglutinin or al ogeneic lymphocytes, and interferon-γwas highly expressed in the supernatant of co-culture of adipose-derived stem cells and mixed lymphocytes. These results indicate that the adipose-derived stem cells have low immunogenicity and can inhibit cellproliferation of lymphocytes in vitro, and the addition of exogenous interferon-γcan enhance the immunosuppressive effects of adipose-derived stem cells.

BACKGROUND:The metastasis ways of colon cancer include blood metastasis, peritoneal metastasis and lymph node metastasis. Among them, the most common metastasis organ is the liver. It is necessary to establish a simple, suitable animal model to study the biological behavior of the colon cancer liver metastasis, the heterogeneity of cancer cells, and the mechanism of tumor metastasis. OBJECTIVE:To establish animal model of colon cancer liver metastasis with splenectomy injection method. METHODS:Human colon cancer celllines HT29 were cultured, and subcutaneously transplanted tumor was produced in BALB/c mice. Models of colon cancer liver metastases were established through spleen injection and excision of spleen method. The tumor growth and metastasis, the pathology of transplanted tumor, DNA content and cellcycle of the transplanted tumor were al determined. RESULTS AND CONCLUSION:In this study, we successful y established the model of colon cancer liver metastases through the spleen injection via the dorsal midline incision, the tumor formation rate reached 8/8 (100%). Observation of tissue slice showed that the transplanted tumor was adenocarcinoma I-II. Flow cytometry analysis results showed that DNA ploid was heteroploid DNA. This model provides a good technical platform for biology research for colon cancer metastasis.

Objective To explore the effect of lentiviral vector-mediated somatostatin (SST) expression on seizures induced by hippocampal kindling in rats.Methods Adult Sprague-Dawley rats were randomly divided into the sham group (Sham),epilepsy group (EP),Lenti-pSyn-EGFP (LV-EGFP) group and Lenti-pSyn-SST-2A-EGFP (LV-SST) group.The rats in LV-EGFP group were subsequently electrically hippocampal kindled and LV-EGFP (5 μl) was injected into dentate gyrus (DG).The rats in LV-SST group were kindled and LV-SST (5 μl) was injected into the dentate gyrus (DG),medial entorhinal cortex (MEC) or amygdala (Amy).Seizure severity was evaluated and immunohistochemical staining was employed to detect the expression of SST,neuron specific nuclear protein (NeuN) and microtubule associated protein 2 (MAP2).Results The current values to the first stage V seizure of LV-SST (DG) group,LV-SST (MEC) group or LV-SST (Amy) group ((143.8±3.8)μA,(142.5±4.1)μA,(142.5±5.3) μA,respectively) were significantly increased compared with that of epilepsy (EP) group ((136.3±5.3)μA),and V stage current values of LV-SST groups in each stimulation day were higher than that of EP group except the fifth stimulation day (P<0.05).After kindling,SST expression and NeuN-positive neurons of EP group and LV-SST groups were less than that of Sham group in CA1,CA3 and DG.SST and NeuN neurons loss in LV-SST groups were less than that of EP group (P<0.05) and MAP2 immunohistochemistry stainings in LV-SST groups were higher than that in EP group.Conclusion Lentiviral vector-mediated somatostatin expression suppresses seizures and can rescue the neuronal damage of seizure induced by kindling in hippocampus,which may provide a new method of gene therapy for temporal lobe epilepsy.
