| 1 | Modification of Mn on corrosion and mechanical behavior of biodegradable Mg(88)Y4Zn2Li5 alloy with long-period stacking ordered structure显示文摘The biological corrosion behavior and mechanical properties of Mg(89-x)Y4 Zn2 Li5 Mnx(x=0,0.5,1,1.5 and2 at.%) alloy with long-period stacking ordered(LPSO) structure were investigated in this work.The magnesium matrix and the eutectic phase of Mg(88)Y4 Zn2 Li5 Mn1 alloy are effectively refined by the grain boundary segregation of Mn,and the average size of matrix and the eutectic phase decreased by 66%and 74%,respectively.The ultimate tensile strength(UTS) and elongation enhanced by 36% and 55%,respectively.The corrosion rates obtained by weight loss and hydrogen evolution of Mg(88)Y4 Zn2 Li5 Mn1 alloy were 79% and 84% lower than that of Mg(88)Y4 Zn2 Li5 alloy.Additionally,Mg(88)Y4 Zn2 Li5 Mn1 alloy also presents superior corrosion behavior in electrochemical test.It is verified that Mn plays a positive role in both corrosion and mechanical properties of the Mg(88)Y4 Zn2 Li5 Mn1 alloy,which provides a reference for further experimental work. | Jiaxin Zhang Jinshan Zhang Fuyin Han Wei Liu Longlong Zhang Rui Zhao Chunxiang Xu Jing Dou | 2020 | Journal of Materials Science & Technology2020，42，7： | 4 |
| 2 | Role of blood pressure on stroke-related mortality:a 45-year follow-up study in China显示文摘Background:Hypertension is associated with stroke-related mortality.However,the long-term association of blood pressure(BP)and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown.The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations.Methods:This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020.COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure(SBP)/diastolic blood pressure(DBP)categories and BP changes from 1976 to 1994.The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths.E value was calculated in the sensitivity analysis.Results:Among 1696 participants,the average age was 44.38±6.10 years,and 1124 were men(66.3%).After a 45-year follow-up,a total of 201(11.9%)stroke-related deaths occurred.After the adjustment,the COX proportional hazard model showed that among the participants with SBP≥160 mmHg or DBP≥100 mmHg in 1976,the risk of stroke-related death increased by 217.5%(hazard ratio[HR]=3.175,95%confidence interval[CI]:2.297-4.388),and the adjusted HRs were higher in male participants.Among the participants with hypertension in 1976 and 1994,the risk of stroke-related death increased by 110.4%(HR=2.104,95%CI:1.632-2.713),and the adjusted HRs of the BP changes were higher in male participants.Body mass index(BMI)significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender.Conclusions:In a 45-year follow-up,high BP and persistent hypertension are associated with stroke-related death,and these associations were even more pronounced in male participants.The paths of association are mediated by BMI and moderated by gender. | Shengshu Wang Shanshan Yang Wangping Jia Ke Han Yang Song Jing Zeng Wenzhe Cao Shaohua Liu Shimin Chen Zhiqiang Li Xuehang Li Penggang Tai Fuyin Kou Yao He Miao Liu | 2022 | Chinese Medical Journal2022，，4： | 1 |
