Traditionally it has been widely accepted that our genes together with adult lifestyle factors determine our risk of developing noncommunicable diseases such as type 2 diabetes mellitus ,cardiovascular disease and obesity in lat-er life.Currently, there is substantial evidence that the early life environment plays a key role in determining our suscepti -ble to such diseases in later life .As an increased focus on the understanding of central insulin resistance , central nerve sys-tem plays an extremely important role in regulating the peripheral glucose homeostasis .Substantial studies have indicated that it may be regulated by epigenetic mechanisms .Epigenetics can be defined as the study of heritable changes in gene ex-pression that do not involve alterations in the DNA sequence .Epigenetic processes play a central role in regulating tissue specific gene expression and hence alterations in these processes can induce long -term changes in gene expression and me-tabolism which persist throughout the lifecourse .This review will focus on the epigenetic machanisms of central neuroregula-tion between early life environment and glucose metabolism in adulthood .

As traditional Chinese medicine components have become a hotspot in the field of traditional Chinese medicine study, they have followed a development trend of diversity and false identification. In studies on a new modem product, we shall encourage the diversified development mode, but avoid the false concept identification of traditional Chinese medicine components. In this paper, by analyzing the current development of traditional Chinese medicine components and problems, we discussed the standardization of traditional Chinese medicine components, with the aim of reducing and avoiding the situations to study non-traditional Chinese medicine components as traditional Chinese medicine components.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Background and purpose:Apollon gene is highly expressed in leukemia and other tumors. The study aimed to discuss whether RNAi technology can reverse multidrug resistance of chronic myeloid leukemia cell line K562 through constructing a eukaryotic vector of short hairpin RNA (shRNA) targeting at Apollon gene. Methods:The eukaryotic vector pGPHI-GFP-Neo-Apollon with shRNA targeting at Apollon gene was constructed and then transfected into K562 cells by LipofectamineTM2000, and G418 pressure selection. Reverse transcription-polymerase chain reaction (RT-PCR) and immunolfuorescence were used to detect the expression of Apollon mRNA and protein after Apollon was transfected stably in K562 cells. The changes of sensitivity of K562 cells to leurocristine (VCR) and etoposide (VP16) after transfection with shRNA-Apollon were detected by MTT method, and the apoptosis rate was detected by flow cytometry. Results: pGPHI-GFP-Neo-Apollon carrier was constructed successfully and expressed stably in K562 cells, and after G418 screening, it silenced Apollon mRNA and protein expression effectively. According to the result of MTT, the sensitivity of K562 cells to VCR and VP16 increased significantly in the group of gene interference, with half of its inhibition concentration (half-inhibitory, IC50) value signiifcantly lower than the control group (P<0.05);Flow cytometry showed that the cell apoptosis rate was increased signiifcantly (P<0.05), but there was no statistically signiifcant difference in the apoptosis rate between shRNA negative control group and normal control group (P>0.05). Conclusion:pGPHI-GFP-Neo-Apollon carrier can enhance the abilities of VCR and VP16 to induce the apoptosis of K562 cells, namely an increase of sensitivity to these chemotherapeutics in K562 cells, it is hinted that RNA interference targeting Apollon gene may reverse the multidrug resistance of leukemia cells in some degree.
