Breast cancer has become the most common malignant tumor and the major cause of cancer-related death for women around the world. The number of patients shows an increasing trend recently. Breast cancer is a big threaten to wom?en’s health and quality of life. With the development of molecular biology, molecular biomarkers have been found assiciated with prognosis in patients with breast cancer, which makes it possible to predict cancer patient survival precisely and practi?cally. This review summarized those new developments of biomarkers on the prognosis of breast cancer.

Objective To identify snoRNA, which may be related to prognosis of gastric cancer. Methods Ninetygastric cancer patients who diagnosed at Tianjin Medical University Cancer Institute and Hospital were randomly collected in this study, and their clinical data were followed up. A total of 405 snoRNA expression profiles were analyzed in 90 gastric cancer patients. Patients were classified aslow expressiongroup orhigh expressiongroup according to the median expression of each snoRNA expression, which was calculated by univariate and multivariate survival analysis. We also screened out the snoRNAs, in which patients were survived differently. Patients were classified as high, middle, or low risk groups based on the snoRNA risk score. Values of age, gender, smoking, drinking, histological differentiation (well, moderately-differentiated and poorly differentiated), clinical stage (Ⅰ+Ⅱstage andⅢ+Ⅳstage), tumor size (<5 cm and≥5 cm), tumor location (upper 1/3 and others) and snoRNA risk score (high, middle, and low risk group) were assessed by multivariate Cox analysis. Results There were significant differences in overall survival and (or) progression-free survival rates in 19 patients with high and low snoRNAs expressions (P<0.05). Results of multivariate Cox analysis showed that patients with high expression of ACA61,ACA27 and U36A showed a higher overall survival and progression-free survival rates, while patients with high expression of ENSG00000206898 showed a lower overall survival and progression-free survival survival rates (P<0.01). SnoRNA risk score is an independent prognostic factor for patients with gastric cancer. Compared with low risk group, patients in middle risk group and in high risk group showed a shorter overall survival and progression-free survival rates (P<0.001). Conclusion The expressions of ACA61, ACA27, U36A and ENSG00000206898 are independent prognostic factors of gastric cancer. Low expressions of the first three indexes and high expressions of the last one predict a bad prognosis.

PurposeTo evaluate left ventricular function in patients with non-obstructive hypertrophic cardiomyopathy (HCM) by using three-dimensional speckle tracking imaging (3D-STI).Materials and Methods Twenty-eight patients with non-obstructive hypertrophic cardiomyopathy (HCM group) and 30 healthy volunteers (control group) underwent both conventional two-dimensional echocardiography and 3D-STI. Indexes of conventional echocardiography including interventricular septal thickness (IVST), left ventricular posterior wall at end-diastolic thickness (LVPWT), left ventricular diameter, left ventricular volume, end-systolic left ventricular volume, peak velocity of early diastolic mitral valve, peak diastolic of late diastolic mitral valve, outflow tract frequency spectrum of the aortic valve and left ventricular were compared between the two groups to get the pressure difference and velocity time integral of the left ventricular outflow tract. Early and late diastolic peak velocity of mitral annular were calculated and E/A, Ea/Aa, E/Ea were also obtained. 3D-STI indicators including three-dimensional left ventricular ejection fraction (3D-LVEF), sphericity index (SPI) and global area of strain (GAS), global longitudinal train (GLS), global circumferential strain (GCS), global radial strain (GRS) were also compared.Results In HCM group, IVST, LVPWT and E/Ea increased (P<0.01), Ea/Aa and E/A decreased significantly (P<0.01), LVOT-PG and LVOT-VTI increased significantly (P<0.05 orP<0.01). GCS, GAS, GLS and GRS were significant lower in HCM group than those in control group (P<0.01). Local strain values at the level of papillary muscle and apex were decreased, which were significantly decreased at ventricular septum, anterior wall and inferior wall.Conclusion HCM patients have various degree of decreased myocardial contractility. The real time 3D-STI offers a novel way to assess the left ventricular function of patients with HCM.

OBJECTIVE:To evaluate the efficacy and safety of tiotropium bromide in the treatment of COPD patients and pro-vide evidence-based reference for the clinical treatment.

CONCLUSIONS:Tiotropium bromide has good efficacy in the treatment of COPD. However,it may cause dry mouth. Due to the methodological limitations of included studies,it remians to be further verified by large-sample and high-quality RCT.

Objective To assess the value of nuchal translu-cency in combination with non-invasive prenatal DNA test in fetal with chromosomal disease. Methods A total of 713 cases with single pregnancies, with 11 ~ 14 gestational weeks, were enrolled in this study. We measured the thickness of nuchal translu-cency, If the thickness was abnomal, the pregnant women would receive the non-invasive prenatal DNA test on voluntary basis and were followed up. Results There were 27 cases with abnormal NT among 713 cases. Twenty-one cases received non-invasive prenatal DNA test , the test results showed that 3 cases were trisomy 21 , 1 cases was trisomy 18. Among the 17 cases with normal chromosome karyotype, 6 cases were found abnomal during the follw-up. Two cases were found abnomal among the 6 cases undergo the non-invasive prenatal DNA test.The thickness of NT, ranging from 3.7 mm to 4.4 mm, was trisomy 21, with the average of 4.0 mm, and the thickness of NT was 5.0mm and was trisomy 18. Conclusions The application of nuchal translu-cency in combination with non-invasive prenatal DNA test could improve the ability to find fetal chromosomal disease and to decrease the birth defect.

: To assess the () recombinant gingivalis gingipain R2 (rRgpB)-induced Ca mobilization in human gingival fibroblast (HGF) mediated by protease-activated receptor (PAR) and its downstream signal transduction pathways. : Flow cytometry was used to detect the expression of PAR in HGF. The proliferation of HGF was measured by CCK-8. The dynamic changes of intracellular Ca concentration in HGF induced by rRgpB and the blocking effect of PAR-1 antagonist were observed by laser confocal microscopy. Western blot was performed to determine the phosphorylation levels of c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK) 1/2, p38 mitogen-activated protein kinase (p38 MAPK) and p65 in HGF. : PAR-1 and PAR-3 were expressed in HGF, and the rRgpB could promote the proliferation of HGF. rRgpB caused a transient increase in [Ca], which could be completely suppressed by vorapaxar, a PAR-1 antagonist. The phosphorylation levels of JNK, ERK1/2 and p65 were significantly up-regulated after the induction of rRgpB for and (all <0.05), which was completely inhibited by vorapaxar. However, the phosphorylation level of p38 MAPK had no significant change after rRgpB stimulation. : rRgpB causes an increase in [Ca] in HGF mediated by PAR-1. JNK, ERK1/2 and nuclear factor-κB may be involved in intracellular signal transduction after PAR-1 activation.

This study was aimed to search anti-platelet aggregation effectors from Gardenia jasminoides extract with the employment of platelet affinity extraction method coupled with HPLC, in order to provide pharmacological experi-mental evidences of the selected effectors to verify its feasibility. Under physiological conditions, washed rat platelets were added into G. jasminoides extract and then a mixture was gained. Consequently, some components from G. jas-minoides extract were combined to the platelets in the mixture while some were not owing to their special chemical structures and properties. Firstly, the uncombined components were washed off from the mixture. Secondly, the com-bined components in the leftover was washed down and collected, respectively, right after destroying the occupied platelets' structures. Thirdly, different collected eluents were analyzed, respectively, by HPLC established in the pre-vious work to search the effectors. Fourthly, pharmacological experiments were implemented for confirmation. The re-sults showed that dominant effective components from G. jasminoides extract acting on anti-platelet aggregation were identified as geniposide. Further evident was provided as well by pharmacological experiment that geniposide exhibit-ed significant inhibitory effect on anti-platelet aggregation in rats induced by ADP, rat tail collagen and thrombin(P< 0.01). It was concluded that the platelet affinity extraction-HPLC method proposed in this paper can be utilized to analyze the correlation of effectors from G. jasminoides extract and its pharmacological effects. Moreover, there are some correlations between screened chemical substances and their pharmacological effects.

Objective: To explore the mediating role played by college students social anxiety and social support in the relationship between internet addiction and depression. Methods: A cluster random sampling method was used to conduct a questionnaire survey among 3 536 college students in three higher vocational colleges in Anhui Province. The content included general demographic characteristics, depression, Internet addiction, social support, and social anxiety. The Process program was used to mediate and analysis of regulation. Results: Among the survey subjects, 1 552(43.90%) had depressive symptoms, including 561(45.65%) boys and 991(42.96%) girls.The total score of Internet addiction was significantly positively correlated with depression score(r=0.30, P<0.01); social anxiety(social fear, social avoidance) was positively correlated with depression(r=0.24, 0.27, P<0.01); social support(subjective support, objective support, support utilization) was significantly negatively correlated with depression(r=0.25, -0.23, -0.17, P<0.01). Conditional process analysis shows that social anxiety had a mediating role between internet addiction and depression(c'=0.06, P<0.01), and that Internet addiction and social anxiety were regulated by social support(β=-0.00，P=0.02). Conclusion By increasing the social support of college students to improve social anxiety, it might help to reduce the depression of college students caused by Internet addiction.

Objective: To compare the reliability of Internet Addiction Impairment Index (IAII), Revised Chen Internet Addiction Scale(CIAS-R)-Taiwan Revision, CIAS-R-Mainland Revision, Young Diagnostic Questionnaire (YDQ) and the consistency of Internet addiction using the four scales in college students. Methods: A total of 1 004 undergraduates from 3 universities in Hefei were selected to measure the tendency of internet addiction simultaneously using the four scales, and 122 students were re tested two weeks after the initial assessment. Correlation coefficient, coincidence rate and Kappa value were used to analyze the consistency of the four scales. Analysis of variance, t test and Logistic regression were used to determine the consistency of the factors related to internet addiction scale. Results: The reliability of the four Internet addiction scales were greater than 0.7( P <0.01). The correlation coefficient among all scales was greater than 0.5( P <0.01). The agreement between YDQ and CIAS-R-Mainland Revision was 0.87. The Kappa value of YDQ and CIAS-R-Taiwan Revision in the consistency analysis was 0.51( P <0.01), the Kappa value between the other scales was less than 0.5. Results showed that the four scales were consistent in Internet addiction prevalence by gender, grade and major, while CIAS-R-Taiwan Revision and YDQ were not consistent with the other two scales in sleep disorder. Conclusion The four Internet addiction scales all have good reliability, while low agreement in Internet addiction assessment, suggesting further improvement and revision in Internet addiction scales.
