ObjectiveTo investigate the methods and clinical significance of detecting PLAC4 and COL6A1 gene on fetal chromosome 21 from maternal peripheral blood. Methods From Oct. 2008 to Nov. 2009 30 normal pregnancies in Weifang People's Hospital were selected as pregnant group, and 9 nonpregnant women were selected as control group. Quantitative real-time PCR was used to determine transcript levels of the target genes ( PLAC4 and COL6A1 ) in blood samples. Correlation between the expression level and gestational age was analyzed. Results ( 1 ) PLAG4 mRNA was detected in peripheral blood of all pregnant women. Its maximum level was 12. 760 × 103 copies/ml, whereas the minimum was 2. 105 × 103 copies/ml, and the average value is 6. 612 × 103 copies/ml. In control group the PLAC4 mRNA could not be detected. There was statistically significant difference ( P < 0. 01 ) between the two groups. ( 2 ) COL6A1 mRNA is detected in pregnant group and control group, and the concentration was 6. 847 × 103 copies/ml and 7. 322 × 103 copies/ml respectively, with no statistically significant difference ( P > 0. 05 ). ( 3 ) Correlation analysis: there was no relationship between the level of PLAC4, COL6A1 mRNA and the gestational age, the correlation coefficients (r) were 0. 29 and 0. 31, and the P values were 0. 121 and 0. 168 respectively. Conclusions COL6A1 mRNA can be detected in both pregnant group and control group, so it is not specific for pregnancy. PLAC4 mRNA can be detected only in pregnant women, so it has specificity in pregnancy and can be a discriminative marker gene for prenatal dignosis of trisomy 21 fetuses.

Objective To investigate the effects and mechanism of glucagon-like peptide-1 ( GLP-1 ) receptor agonist liraglutide on the proliferation and apoptosis of human pancreatic cancer cells. Methods The human pancreatic cancer cell line MIA PaCa-2 was incubated for 24 h with liraglutide at various concentrations (10-1 000 nmol/ L), or with 100 nmol/ L liraglutide for various durations (0-72 h). Cell proliferation was determined by Cell Counting Kit-8 (CCK-8) analysis. RT-PCR and Western blot were used to detect the mRNA and protein expression levels of related genes. Results GLP-1 receptor was expressed in the MIA PaCa-2 cells. Liraglutide suppressed cell proliferation, up-regulated the expression levels of pro-apoptotic protein Bax and down-regulated the expression levels of anti-apoptotic protein Bcl2 in human pancreatic cancer cells in a dose- and time-dependent manner. Meanwhile, liraglutide down-regulated the expression levels of insulin receptor (INSR) and insulin-like growth factor-1 receptor (IGF-1R), and the phosphorylation levels of their downstream signaling proteins Erk1 / 2 and Akt, in a dose- and time-dependent way. Conclusion Liraglutide inhibits proliferation and promotes apoptosis of human pancreatic cancer cells; the process may be mediated via suppressing the expression of INSR and IGF-1R and inhibiting activation of the downstream MEK/ Erk1 / 2 and PI3k/ Akt pathways.

Objective:Reflux esophagitis (RE) may be negatively correlated with Helicobacter pylori ( H. pylori) infection, but the conclusion and relevant mechanism is still controversial. This study proposed to explore the correlation between RE and H. pylori infection based on natural population. Methods:From July 2013 to December 2014, 3 940 residents aged 40-69 years were recruited in Linqu County of Shandong Province and Hua County of Henan Province by the whole sampling method. All the subjects underwent gastroscopy, and gastric mucosa biopsy specimens were collected for pathological diagnosis and Warthin-Starry (WS) staining to identify H. pylori infection. Venous blood samples of some subjects were collected for H. pylori immunoglobulin G ( H. pylori-IgG) detection. Also, demographic and sociological data were collected. Chi-square test and logistic regression were used to analyze the correlation between RE and H. pylori infection. Results:A total of 359 cases of RE were detected. Excluding RE and other upper gastrointestinal organic diseases, 3 382 cases were considered as controls. Chi-square test showed that WS staining positive rate in RE group was significantly lower than that in control group ( P=0.023), but there was no significant difference in the positive rate of H. pylori-IgG between the two groups ( P=0.281). There were significant differences between RE group and control group in gender composition, age, body mass index (BMI), smoking, alcohol consumption, education level and mucosal active inflammation. Multivariate regression analysis showed that RE was negatively correlated with gastric mucosa active inflammation [ OR=0.754 (95% CI 0.600-0.949), P=0.016], and positively correlated with male [ OR=4.231 (95% CI 3.263-5.486), P<0.001], age ≥60 years, BMI≥24 kg/m 2 [ OR=1.540 (95% CI 1.220-1.945), P<0.001]. Compared to those aged 40-49 years and 50-59 years, the odds ratio ( OR) of RE in these aged ≥60 years were 1.566 (95% CI 1.144-2.143, P=0.005) and 1.405 (95% CI 1.093-1.805, P=0.008). Conclusion:RE is more closely related to H. pylori present infection. Multivariate analysis showed that RE is negatively correlated with active inflammation of gastric mucosa caused by H. pylori infection, and positively correlated with male, overweight and aged ≥60 years.

Objective To investigate the overweight status of military officers and soldiers and to analyze the risks of the induction of chronic diseases. Methods Questionnaires and biochemical analysis were used to randomly survey the living and training status of 485 officers and soldiers in a military unit. Blood and urine samples were collected and analyzed using blood biochemical analysis methods and conventional dry chemical methods. Statistical analysis was performed through EXCEL 2007 and SPASS 12.0 software. Results The survey results showed that the proportion of BMI abnormal people in the officers and soldiers was high. Compared to the normal population, the officers and soldiers with abnormal BMI had more bad daily life habits such as smoking and drinking, while their diet balance was relatively poor, and their frequency of daily exercise was significantly less. Biochemical tests showed that the proportion of the officers and soldiers with hyperuricemia and hyperbilirubinemia was high, but there was no significant difference in the officers and soldiers with different BMI. Urine analysis showed that the number of urinary protein and occult blood in the officers and soldiers increased significantly after military training, and the BMI abnormal population was more significant than the normal population. Conclusion There was a relatively low correlation between different BMI and chronic metabolic diseases in military officers and soldiers, but those with abnormal BMI were at high risk for exercise-induced kidney injury. Military officers and soldiers should strengthen health management and actively control the acquired factors that cause BMI abnormalities, to effectively prevent and reduce the BMI abnormality and lower the risk of induced early chronic kidney injury disease, promoting the overall health level.
