Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

Objective Using the Chinese anthropomorphic chest phantom to measure the absorbed dose of various tissues and organs under different noise index, and to assess the radiation dose of MSCT chest scanning with the effective dose(ED). Methods The equivalence of the Chinese anthropomorphic chest phantom(CDP-1C) and the adult chest on CT sectional anatomy and X-ray attenuation was demonstrated. The absorbed doses of various tissues and organs under different noise index were measured by laying thermoluminescent dosimeters(TLD) inside the phantom, and the corresponding dose-length products(DLP) were recorded. Both of them were later converted into ED and comparison was conducted to analyze the dose levels of chest CT scanning with automatic tube current modulation (ATCM) under different noise index. Student t-test was applied using SPSS 12.0 statistical software. Results The Phantom was similar to the human body on CT sectional anatomy. The average CT value of phantom are -788.04 HU in lung,45.64 HU in heart,65.84 HU in liver,254.32 HU in spine and the deviations are 0.10%,3.04%, 4.49% and 4.36% respectively compared to humans. The difference of average CT value of liver was statistically significant(t=-8.705,P<0.05),while the differences of average CT values of lung, heart and spine were not significant(t value were -0.752,-1.219,-1.138,respectively and P>0.05).As the noise index increased from 8.5 to 22.5, the DLP decreased from 393.57 mGy·cm to 78.75 mGy·cm and the organs dose declined. For example, the average absorbed dose decreased from 22.38 mGy to 3.66 mGy in lung. Compared to ED calculating by absorbed dose, the ED calculating by DLP was lower. The ED values of the two methods were 6.69 mSv and 8.77 mSv when the noise index was set at 8.5. Conclusions Application of the Chinese anthropomorphic chest phantom to carry out CT dose assessment is more accurate. The noise index should be set more than 8.5 during the chest CT scanning based on ATCM technique.
