2Up-regulation of PIK3CA promotes metastasis in gastric carcinoma显示文摘AIM:To explore expressions of PIK3CA in the progression of gastric cancer from primary to metastasis and its effects on activation of phosphatidylinositol 3-kinase(PI3K)/Akt pathway.METHODS:mRNA and protein levels of PIK3CA were assessed,respectively,by real-time quantitative polymerase chain reaction and immunohistochemistry in specimens of normal gastric mucosa,primary foci and lymph node and distant metastasis of gastric cancer.Akt and phosphorylated Akt protein were also examined by Western blotting in these tissues,in order to analyze the effect of PIK3CA expression level changes on the activation of PI3K/Akt signaling pathway.RESULTS:PIK3CA mRNA in lymph node metastasis were approximately 5 and 2 folds higher,respectively,than that in the corresponding normal gastric mucosa and primary gastric cancer tissues(P<0.05),while no statistical significance was found compared with distant metastasis.Immunohistochemically,PIK3CA protein expression was discovered in 7(35%)specimens of 20 primary foci vs 10(67%)of 15 of lymph node metastasis or 11(61%)of 18 of distant metastasis(35%vs 67%,P=0.015;35%vs 61%,P=0.044).With the increased level of PIK3CA expression,the total Akt protein expression remained almost unchanged,but p-Akt protein was upregulated markedly.CONCLUSION:Increased expression of PIK3CA is expected to be a promising indicator of metastasis in gastric cancer.Up-regulation of PIK3CA may promote the metastasis of gastric cancer through aberrant activation of PI3K/Akt signaling.Liu JF Zhou XK Chen JH Yi G Chen HG Ba MC Lin SQ Qi YC. 2010World Journal of Gastroenterology2010,16,39:20

5Co-effect of Demand-control-support Model and Effort-reward Imbalance Model on Depression Risk Estimation in Humans: Findings from Henan Province of China显示文摘Objective To investigate the co-effect of Demand-control-support(DCS) model and Effort-reward Imbalance(ERI) model on the risk estimation of depression in humans in comparison with the effects when they are used respectively. Methods A total of 3 632 males and 1 706 females from 13 factories and companies in Henan province were recruited in this cross-sectional study. Perceived job stress was evaluated with the Job Content Questionnaire and Effort-Reward Imbalance Questionnaire(Chinese version). Depressive symptoms were assessed by using the Center for Epidemiological Studies Depression Scale(CES-D). Results DC(demands/job control ratio) and ERI were shown to be independently associated with depressive symptoms. The outcome of low social support and overcommitment were similar. High DC and low social support(SS), high ERI and high overcommitment, and high DC and high ERI posed greater risks of depressive symptoms than each of them did alone.ERI model and SS model seem to be effective in estimating the risk of depressive symptoms if they are used respectively. Conclusion The DC had better performance when it was used in combination with low SS. The effect on physical demands was better than on psychological demands. The combination of DCS and ERI models could improve the risk estimate of depressive symptoms in humans.YU Shan Fa NAKATA Akinori GU Gui Zhen SWANSON Naomi G ZHOU Wen Hui HE Li Hua WANG Sheng 2013Biomedical and Environmental Sciences2013,26,12:8

9A Comparison Between Northern Blotting and Quantitative Real-Time PCR as a Means of Detecting the Nutritional Regulation of Genes Expressed in Roots of Arabidopsis thaliana显示文摘Quantitative real-time PCR (qRT-PCR) has become a routine and robust technique for measuring the expression of genes of interest, validating microarray experiments and monitoring biomarkers. However, concerns have been raised over the accuracy of qRT-PCR in China as well as in the rest of the world. We have previously used qRT-PCR to study the response of ANR1 and other root-expressed MADS-box genes to fluctuations in the supply of nitrate, phosphate and sulphate under hydroponic growth conditions. In this study, we have used both Northern blotting and qRT-PCR analyses to confirm the nutritional regulation of MADS-box genes in Arabidopsis thaliana and test whether both technologies produce the same results. The information obtained indicated that the qRT-PCR results are consistent with those obtained by Northern blotting hybridization for all the tested root-expressed MADS-box genes, in response to different nitrate, phosphate and sulphate growth conditions. Furthermore, our novel results showed that the expressions of AGL12, AGL18, and AGL19 were all down regulated in response to S and P re-supply in both qRT-PCR and Northern blotting analyses.GAN Yin-bo ZHOU Zhong-jing AN Li-jun BAO Sheng-jie Brian G Forde 2011Agricultural Sciences in China2011,10,3:4

11Cervical inlet patch-optical coherence tomography imaging and clinical significance显示文摘AIM:To demonstrate the feasibility of optical coherence tomography(OCT)imaging in differentiating cervical inlet patch(CIP)from normal esophagus,Barrett'sesophagus(BE),normal stomach and duodenum. METHODS:This study was conducted at the Veterans Affairs Boston Healthcare System(VABHS).Patients undergoing standard esophagogastroduodenoscopy at VABHS,including one patient with CIP,one representative patient with BE and three representative normal subjects were included.White light video endoscopy was performed and endoscopic 3D-OCT images were obtained in each patient using a prototype OCT system.The OCT imaging probe passes through the working channel of the endoscope to enable simultaneous video endoscopy and 3D-OCT examination of the human gastrointestinal(GI)tract.Standard hematoxylin and eosin(H and E)histology was performed on biopsy or endoscopic mucosal resection specimens in order to compare and validate the 3D-OCT data. RESULTS:CIP was observed from a 68-year old male with gastroesophageal reflux disease.The CIP region appeared as a pink circular lesion in the upper esophagus under white light endoscopy.OCT imaging over the CIP region showed columnar epithelium structure,which clearly contrasted the squamous epithelium structure from adjacent normal esophagus.3D-OCT images obtained from other representative patients demonstrated distinctive patterns of the normal esophagus,BE,normal stomach,and normal duodenum bulb.Microstructures,such as squamous epithelium,lamina propria, muscularis mucosa,muscularis propria,esophageal glands,Barrett's glands,gastric mucosa,gastric glands, and intestinal mucosal villi were clearly observed with OCT and matched with H and E histology.These results demonstrated the feasibility of using OCT to evaluate GI tissue morphology in situ and in real-time. CONCLUSION:We demonstrate in situ evaluation of CIP microstructures using 3D-OCT,which may be a useful tool for future diagnosis and follow-up of patients with CIP.Chao Zhou Tejas Kirtane Tsung-Han Tsai Hsiang-Chieh Lee Desmond C Adler Joseph M Schmitt Qin Huang James G Fujimoto Hiroshi Mashimo 2012World Journal of Gastroenterology2012,18,20:3
