1.17q21 loci gene and childhood asthma
International Journal of Pediatrics 2017;44(7):471-474
Asthma,a chronic inflammatory airway disease,is influenced by both genetic and environmental factors.It is a complex disease that involves the interplay among multiple physiological processes.Currently,it has been identified that 17q21 loci genes especially orosomucoid like 3 (ORMDL3) and gasdermin B (GSMDB) are strongly linked with the susceptibility and severity of childhood asthma by using of the Genome-Wide Association Study (GWAS).Furthermore,a better understanding of the molecular mechanism contributes to the asthma target therapeutics and precision medicine.This review summarizes the 17q21 loci genes associated with the susceptibility,severity,and race specificities of childhood asthma.

AIM To study the effects of neferine on gastric car cinoma apoptosis induced by vincristine in vitro. METHODS Cytotoxicity assay was tested by MTT method. The influence of neferine to affect vincristine to induce gastric carcinoma apoptosis was detected by PI staining flow cytometry, AO/EB double fluorescence stain and terminal deoxynucleotidyl transferase mediated nick end labeling (TUNEL). RESULTS 2 5, 5,10 ?mol?L -1 neferine enhanced vincristine to inhibit the proliferation of SGC7901 cells; 10 ?mol?L -1 neferine enhanced vincristine (0 1, 0 5, 2, 4 mg?L -1 ) to induce SGC7901 cells apoptosis. CONCLUSIONS Neferine enhanced vincristine to induce gastric carcinoma cells apoptosis. It is inferred a kind of low poisonous and high effective chemosenstizers.

Objective To investigate the alien snails in Dapeng Peninsula Shenzhen City. Methods The survey on the snail diversity in Dapeng Peninsula was carried out from August 2012 to Jan 2013 and the species of the alien snails were iden?tified according to the shell morphology. Results Four species of alien snails including Achatina fulica Pomacea canalicula?ta Physa acuta and Biomphalaria straminea were found in Dapeng Peninsula P. acuta was found in all of the collected sites A. fulica and P. canaliculata were distributed in five regions except Yangmeikeng area and B. straminea was just found in Dapeng Town. Conclusion Four species of important alien snails invade widely in Dapeng Peninsula Shenzhen City. As their potential risk to the disease transmission and agriculture production the relative departments should strengthen the control and prevention.

1.15). Rosiglitazone at the concentration of 1.25 ?mol?L -1 augme nted the induction apoptosis of A549 cells by treatment with Cisplatin at variou s concentrations of 1.98 mg?L -1, 2.8 mg?L -1 and 4.0 mg?L -1 . A549 cells treated with Rosiglitazone at concentration of 1.25 ?mol?L -1 domostrated nuclear traslocations of PPAR? protein and down-regulation of Bcl-2 protein. Conclusion The ligand of PPAR? Rosiglitazone enhanc ed the inhibition of proliferation and induction of apoptosis by treatment with Cisplatin in A549 cells cultured in vitro. Activation of PPAR? protein and the down-regulation of Bcl-2 possiblely play an improtant role in chemosenstiz eic mechanism of Rosiglitazone in vitro.

Aim To explore the role of a peroxisome proliferators-activated receptor gamma ligand,Rosiglitazone,in angiogenesis in human lung adenocarcinoma cells with reference to the regulation of vascular endothelial growth factor(VEGF).Methods Human lung adenocarcinoma A549 cell line was cultured in vitro.Expression of PPAR? and VEGF in A549 lung adenocarcinoma cells treated with different concentrations of Rosiglitazone was examined by semi-quantitative RT-PCR and immunohistochemical staining.Results PPAR? protein levels were higher in cultured A549 cells.RT-PCR and immunohistochemical staining showed that PPAR? mRNA and protein were enhanced in cells treated with Rosiglitazone in a dose-dependent manner,compared with those of untreated cells.Rosiglitazone had a potent inhibitory effect on the expression of VEGF in A549 cells dose-dependently in a range of concentrations.The effect was maximal with 10 ?mol?L~(-1) RSG and weaken over 20 ?mol?L~(-1) RSG,whereas 100 ?mol?L~(-1) RSG didnot have this down-regulation.GW9662,a PPAR? antagonist,partially blocked this effect of Rosiglitazone.Conclusions Activation of PPAR? suppresses angiogenesis in human lung adenocarcinoma.This action is probably associated with the down-regulation of angiogenic factor,VEGF,which may be modulated by PPAR?.These results suggest that PPAR? might be a novel molecular target for angiogenesis lung adenocarcinoma.

Aim To investigate the molecular mechanism of Rosiglitazone on the expression of integrin ?1 in lung pulmonary carcinoma A549 cell line. Methods RT-PCR and flow cytometry methods were used to examine the expression of mRNA and cell total protein of PPAR? and integrin ?1 subunit. Results The expression of PPAR? mRNA and integrin ?1 mRNA had dose-dependent regulating action by Rosiglitazone,using PPAR? inhibitor GW9662 and ERK pathway inhibitor PD98059 could abolish the inhibition of PPAR? on the expression of integrin ?1. Conclusion The effect of PPAR? ligand Rosiglitazone on integrin ?1 expression is mediated through PPAR?-dependent signaling parthway. The mechanism may be partly involved in ERK pathway.

Objective To understand the gene characteristics of envelope region of human T lymphotropic virus type Ⅰ(HTLV Ⅰ)from Shantou region of China. Methods The gene of proviral envelope region of HTLV Ⅰ Shantou strain (named HTLV Ⅰ WHP)was amplified by PCR,using 4 designed primers,and then was sequenced,meanwhile it was compared with that of various HTLV Ⅰ representative strains from all around the world,and subsequently it was analyzed to construct its phylogenetic tree.Results The nucleotide sequence of complete envelope region of HTLV Ⅰ WHP provirus we have obtained was 1466 bp.There no deletion and insertion in the deducted amino acid sequence.The results of phylogenetic tree analysis showed that the HTLV Ⅰ WHP strain was most closed to some of the strains from Japan and Caribbean,and like the latter,belonged to the subtypea of cosmopolitan group.Conclusion The HTLV Ⅰ strains either from the coastal region of Southeast China or from Japan,Caribbean and so on have the common origin of evolution.
