制得不同粒径空心微珠/环氧复合材料,并对其进行断口形貌、阻尼性能和耐热性进行了研究。其阻尼性能的测试是采用动态力学热分析仪,通过拉伸-压缩的方法在不同变温（-40-150℃）和变频（10-800Hz）条件下完成的。结果表明相同条件下,添加过筛100-140目空心微珠的复合材料在玻璃化转变温度（Tg）下的阻尼性能相对较好（tanδmax=0.892）,并且随频率增加损耗因子衰减较慢。通过复合材料断口的扫描观察发现空心微珠均匀分布在基体中,且与基体的结合较好;通过热重测试发现空心微珠概率粒径越大,复合材料耐热性越好。

BACKGROUND The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease(CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project(Prediction for Atherosclerotic Cardiovascular Disease Risk in China).METHODS A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors(LFs)(smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios(HRs) and corresponding 95% confidence intervals(CIs). The risk advancement periods(RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage(PAR%) were also *** A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1healthy LFs, maintaining 3–4 healthy LFs was associated with a 40% risk reduction of incident CVD(HR = 0.60, 95% CI: 0.45–0.79)and delayed CVD risk by 6.31 years(RAP:-6.31 [-9.92,-2.70] years). The PAR% of maintaining 3–4 unhealthy LFs was 22.0%compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2to 3–4 was associated with a 23% lower risk of CVD(HR = 0.77, 95% CI: 0.60–0.98).CONCLUSIONS Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

Dear Editor,Zika virus（ZIKV）used to be an unknown mosquito-borne flavivirus,and maintained its limited sylvatic circulation in a few African and Asian countries（Enfissi et al.,2016）.Based on available clinical data,the symptoms in human infections with ZIKV are supposed to be similar to other arbovirus infections such as dengue,and characterized by fever,skin rashes,conjunctivitis,muscle and joint pain,malaise,and headache（Duffy et al.,2009）.

Background In China,lack of evidence remains a significant challenge for the national initiative to promote physical activity(PA).We aimed to quantify the beneficial effects of meeting or maintaining the recommended PA level[150 minutes per week(min/wk)of moderate PA or 75 min/wk of vigorous PA or an equivalent combination]on incident cardiovascular disease(CVD)among Chinese *** We included 100,560 participants without history of CVD from three cohorts in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)*** proportional hazards models were used to estimate hazard ratios(HRs)and 95%confidence intervals(CIs)for CVD events and its subtypes,including stroke,coronary heart disease,heart failure,and CVD *** During a median follow-up of 7.3 years(range:6–15 years),777,163 person-years and 4693 incident CVD events were *** with participants who were inactive at baseline,the multivariable adjusted HR(95%CI)of developing CVD was 0.74(0.69–0.79)for those who met recommended moderate to vigorous physical activity(MVPA)level at ***,the risk of CVD incidence was reduced with increment of MVPA(Ptrend<0.001),and the HR(95%CI)of highly-active versus inactive category was 0.62(0.56–0.68).Compared with individuals who were inactive both at the baseline and follow-up,those keeping active over the period of follow-up had a substantial lower risk of incident CVD with the HR(95%CI)of 0.57(0.43–0.77).Conclusions The findings demonstrated that meeting and maintaining the recommended MVPA level could reduce the cardiovascular *** adoption of the PA recommendations would have considerable health impacts to the Chinese population.

Background： Approximately 15-20% cases of systemic lupus erythematosus （SLE） are diagnosed in children. There have been a Few studies reporting the epidemiological data of pediatric-onset SLE （cSLE） in China, neither comparing the differences between cSLE and adult-onset SLE （aSLE）. The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group （CSTAR） database. Methods： We made a prospective study of 225 cSLE patients （aged 〈16 years） and 1759 patients aged 16-50 years based on CSTAR registry. We analyzed initial symptoms, clinical presentations, SLE disease activity, damages, and outcomes ofcSLE, as well as compared with aSLE patients. Results： The mean age ofcSLE patients was 12.16 ± 2.92 years, with 187 （83.1%） females. Fever （P 〈 0.001） as well as mucocutaneous （P 〈 0.001 ） and renal （P = 0.006） disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects （P 〈 0.001 ）. The eSLE patients were found to present more fi＇equently with malar rash （P = 0.001; odds ratio {OR], 0.624; 95% confidence interval [CI ], 0.470 0.829） but less tYequently with arthritis （P 〈 0.001 ; OR, 2.013; 95% CI, 1.512-2.679） and serositis （P = 0.030; OR, 1.629; 95% CI, 1.053 2.520）. There was no significant difl＇erence in SLE disease activity index scores between cSLE and aSLE groups （P = 0.478）. Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients （hazard ratio 0.335 [0.170 0.658], P = 0.001）. The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test （0.557, P = 0.455）. Conclusions： cSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difl＇erence in 5- year survival bet
