Abstract： [Purpose/significance] To fill the gap and inconsistencies on the influencing factors of social media burnout, this research analyzed and summarized the statistical results in existing empirical research using quantitative analysis.[Method/process] In this study, 72 groups of 224 effect values were extracted from 68 empirical research documents, and the influencing factors of social media fatigue were summarized into two major factors:situation and ontology, and five moderators were extracted, including platform type, cultural characteristics, social media use degree, user gender and test group. Using meta-analysis, this paper discussed the influence of different factors on social media fatigue through heterogeneity test and sub-group test, and tested the significance of moderators.[Result/conclusion] The results show that both situational factors and ontological factors have a significant positive influence on social media fatigue. Both of them have a stronger influence on social media psychological fatigue than on social media behavioral fatigue, and there is a higher correlation between situational factors and social media fatigue. At the same time, the five types of moderating factors identified in this study moderated the relationship between ontological factors and social media fatigue, while the relationship between situational factors and social media fatigue is only regulated by the subjects.

Abstract：
[Objective] This study aims to explore the relationship between staying up late, different development levels of cities and life satisfaction with the method of big data in Weibo, so as to increase the understanding of life satisfaction of contemporary people. [Method]The users in Weibo were divided into those who stayed up late and didn't stay up late in first-tier cities and other cities according to user’s information of blog posting. In addition, the statistical difference in life satisfaction between people who stayed up late and didn't stay up late in different areas was compared. [Results] (1) The life satisfaction of Weibo users who stayed up late was significantly higher than that of non-staying up late group (t = 11.768, p < 0.05); (2) Life satisfaction of Weibo users in first-tier cities was significantly lower than that of users in other cities (t =-4.135, p < 0.05); (3) The life satisfaction of staying up late in first-tier cities was significantly lower than that of staying up late in other cities (p < 0.05), and there was no statistically significant difference between non-staying up late in first-tier cities and non-staying up late in other cities (p > 0.05); (4) The life satisfaction of staying up late in first-tier cities was significantly higher than that of non-staying up late in first-tier cities (p < 0.05), and that of staying up late in other cities was significantly higher than that of non-staying up late (p < 0.05). [Conclusion] The staying up late behavior of contemporary Weibo users will improve their life satisfaction to a certain extent. However, the life satisfaction of Weibo users in first-tier cities is lower than that of Weibo users in other cities. "

Abstract： " The issue of stability and variability of values has always been the focus of debate in this field. In recent years, researchers began to analyze the mechanism of the differences in the stability of values from the perspective of cognitive neuroscience. The existing neurophysiological evidence shows that when a certain value is constructed based on the absolute rules of deontology, or is consistent with the representation of self-concept, it tends to maintain a stable state. Otherwise, it may change fundamentally under the persuasion of others. In the future, it is necessary to further enrich and improve the cognitive neural processing model that recognizes the relationship between the stability and variability of values, and explore the cognitive neural mechanisms behind the long-term changes in values, so as to promote the practice and application of theoretical research in values education.

Abstract： Menopausal hormone therapy(MHT) is the medical treatment that mitigates menopausal symp-toms with administration of supplementary sexual hormones. Estrogen and progesterone are often involved in MHT.Experts from The Department of Gynecologic Endocrine and Breast Surgery have paid special attention to the risk of breast carcinoma related to MHT and reached consensuses on the following issues:MHT increases the risk of breast carcinoma;decision should be made after a careful and comprehensive assessment of the risk of breast carcinoma and the potential benefit of MHT. Since the administration of MHT has a window period，a thorough discussion with patients is essential to fully inform the indication and contraindication of MHT，and an informed consent should be obtained. There are still controversies over the risk of breast carcinoma with natural progesterone，tibolone，and single estrogen.

Abstract： Objection:To investigate the clinical and pathological features and the follow-ups of 173 patients with pathological nipple discharge,and to provide the evidence of diagnosis and treatment.Methods:We reviewed the data of the patients who suffered pathological nipple discharge and as well underwent surgery in 2015.Statistical analysis was conducted by spss 22.0.T test and Mann-Whitney U test,X2 test and Fisher exact test were engaged in mean comparision,comparision of count data.Result: There were no statistically significant difference in age，unilateral/ bilateral， single/multiple symptoms, duration of symptoms, positive findings of physical examination and Mammography between patients with bloody nipple discharge or not. Ultrasound revealed more positive findings in patients with bloody nipple discharge (P=0.016). Compared with unbloody discharge ,patients with bloody discharge showed higher rate of breast cancer(P=0.048).Among patients with bloody discharge, ages were significantly different between patients with and without breast cancer (P= 0.014) .Other factors showed no difference.Overall, no local or systemic recurrence or death was observed at a median follow-up of 17months. Conclusion: Bloody nipple discharge showed more risk of breast cancer, especially for the elder patients. Ultrasound revealed more lumps than physical examination and mammography. Since the examinations could not find the malignant lesions out of the symptoms of nipple discharge, surgery was always needed.

Abstract： Objective To investigate the effect of γ-secretase inhibitor (N-[N-(3,5-difluorophenacetyl)-l -alanyl]-S-phenylglycine t-butyl ester, DAPT) on hyperoxia-induced brain white matter injury in mice. Methods Three-day-old C57BL/10J mouse pups were divided into air control (C) group, control+DAPT (10 mg/kg, injected intraperitoneally) group, hyperoxia group (exposed to 80% oxygen for 48 h), and hyperoxia+DAPT group. The brain and body weights of the mice were measured at postnatal days 3, 5, 12, and 28. Real-time PCR was used to detect Notch intracellular domain (NICD) mRNA expression in the brain after modeling, and the expressions of NG2 and myelin basic protein (MBP) were detected by double-labeled immunofluorescence assay to verify the oligdendrocycle type at postnatal day 12. The mice in each group were bred until postnatal day 28 for Morris water maze test. Results The brain and body weights were significantly decreased in mice in hyperoxia group compared to the control mice, but increased significantly after DAPT treatment (P<0.05). Real-time PCR showed that a 48-hour hyperoxia exposure significantly increased NICD mRNA expression in the brain (P<0.05), which was decreased by co-treatment by DAPT (P<0.05). Hyperoxia also resulted in enhanced NG2 expression and lowered MBP expression in the brain (P<0.05). Compared with the control mice, the mice exposed to hyperoxia showed prolonged escape latency (P<0.05) and spent less time in the target quadrant with a lowered number of passing through the virtual platform (P<0.05). All these parameters were significantly improved by co-treatment with DAPT. Conclusion Specific inhibition of Notch signaling pathway activation in the brain by the γ-secretase inhibitor DAPT can ameliorate white matter injury and learning and memory impairment in newborn mice with hyperoxia exposure.
