目的评估淄博市PM_(10)暴露对居民非意外死亡的超额死亡风险。方法收集淄博市2017—2019年每日居民非意外死亡资料、气象及大气污染数据,利用符合泊松分布的广义相加模型进行时间序列分析,并进行超额死亡风险评估。结果2017—2019年淄博市年均PM_(10)浓度为112.07μg/m^(3),呈现年度降低趋势,日均非意外死亡79例。PM_(10)年均浓度和人群非意外死亡总体均呈现中心城区高、外围区县低的空间分布特征。居民非意外死亡风险随着PM_(10)浓度的增加而升高,PM_(10)日均浓度每增加10μg/m^(3),人群非意外死亡的超额危险度ER为0.36%(95%CI:0.18%~0.54%)。当参考浓度分别为150、70μg/m^(3)时,2017—2019年归因于PM_(10)的非意外总超额死亡人数分别为380、1504例;以2019年PM_(10)浓度(105μg/m^(3))为参考浓度,2017—2019年由于PM_(10)浓度降低可避免非意外死亡324例。结论PM_(10)暴露可导致人群超额死亡风险增加,PM_(10)浓度降低可导致超额死亡风险逐年降低。

Background: Compared with Caucasians, unique demographic and clinical features have been reported in Chinese patients with malignant melanoma, but similar comparative studies of melanocytic nevi (MN) are lacking. This study examined the clinical and dermoscopic features of MN in surgically treated Chinese cases. Methods: Clinical data and dermoscopic findings from 1046 cases of MN were collected and analyzed. Cases were treated from January 1 to December 31, 2014 at the Department of Dermatology and Venerology, Peking University First Hospital. The association between nevi location and histologic subtypes was examined with Chi-squared test and univariate logistic regression. Chi-squared test was also used to analyze the proportion of globular patterns across different body sites, and proportion of parallel furrow patterns across different histologic subtypes. Results: The majority of the nevi were from female patients, irrespective of location. The range of age at the time of nevi onset was from 0 (birth) to 79 years. There were 381 (36.4%, 381/1046) congenital nevi;of these 81.6%(311/381) were present at birth. Nevi appeared before 30 years of age in 83.2%(870/1046) of the cases. Median values of length growth rate in congenital and acquired MN were 2.0 and 1.6, respectively. Median values of length growth rates in four age groups (0–9, 10–19, 20–29, and ≥30 years) of congenital nevi were 2.2, 2.0, 2.4, and 2.0, respectively. In acral nevi, which often need to be differentiated from acral lentiginous melanoma, 50.2%(109/217) were junctional (odds ratio [OR];95% confidence interval [CI]: 91.572 [52.210–160.959], P < 0.05). Acral location was also associated with a higher likelihood of compound nevi subtype (OR [95% CI]: 14.468 [8.981–23.306], P < 0.05). The globular (59.4%, 354/596) and pseudonetwork (48.8%, 291/596) dermoscopic patterns were often seen in the head and neck region. In areas other than head and neck and acral regions, the globular pattern was the com

NaBH_(4) was widely regarded as a low-cost hydrogen storage material due to its high-mass hydrogen capacity of approximately 10.8%(mass)and high volumetric hydrogen capacity of around 115 g·L^(–1).However,it exhibits strong stability and requires temperatures above 500℃ for hydrogen release in practical *** this study,two polyhydric alcohols,xylitol and erythritol(XE),were prepared as a binary eutectic sugar alcohol through a grinding-melting *** binary eutectic sugar alcohol was used as a proton-hydrogen carrier to destabilize NaBH_(4).The 19NaBH_(4)-16XE composite material prepared by ball milling could start releasing hydrogen at 57.5℃,and the total hydrogen release can reach over 88.8%(4.45%(mass))of the theoretical *** the 19NaBH_(4)-16XE composite was pressed into solid blocks,the volumetric hydrogen capacity of the block-shaped composite could reach 67.2 g·L^(–1).By controlling the temperature,the hydrogen desorption capacity of the NaBH_(4)-XE composite material was controllable,which has great potential for achieving solid-state hydrogen production from NaBH_(4).
