| 1 | Research progress in the heat resistance, toughening and filling modification of PLA显示文摘Due to its high strength, high modulus, excellent clarity, good biodegradability and biocompatibility, poly(lactic acid)(PLA), a bio-based thermoplastic polyester, has evolved into a competitive commodity material with potential to replace conventional petrochemical-based polymers. However, the wide applications of PLA have been hampered by its native drawbacks, such as low heat distortion temperature(HDT), inherent brittleness and relatively high cost. In recent years, researchers have devoted to breaking above-mentioned bottleneck and attempted to extend the application of PLA. This review will summarize recent work about the modification of PLA, especially focusing on enhancing HDT, toughening and reducing cost. | Yong Yang Lisheng Zhang Zhu Xiong Zhaobin Tang Ruoyu Zhang Jin Zhu | 2016 | Science China Chemistry2016，59，11： | 18 |
| 2 | Oscillation of Surface PM2.5 Concentration Resulting from an Alternation of Easterly and Southerly Winds in Beijing: Mechanisms and Implications显示文摘We used simultaneous measurements of surface PM_(2.5) concentration and vertical profiles of aerosol concentration,temperature, and humidity, together with regional air quality model simulations, to study an episode of aerosol pollution in Beijing from 15 to 19 November 2016. The potential effects of easterly and southerly winds on the surface concentrations and vertical profiles of the PM_(2.5) pollution were investigated. Favorable easterly winds produced strong upward motion and were able to transport the PM_(2.5) pollution at the surface to the upper levels of the atmosphere. The amount of surface PM_(2.5) pollution transported by the easterly winds was determined by the strength and height of the upward motion produced by the easterly winds and the initial height of the upward wind. A greater amount of PM_(2.5) pollution was transported to upper levels of the atmosphere by upward winds with a lower initial height. The pollutants were diluted by easterly winds from clean ocean air masses. The inversion layer was destroyed by the easterly winds and the surface pollutants and warm air masses were then lifted to the upper levels of the atmosphere, where they re-established a multi-layer inversion. This region of inversion was strengthened by the southerly winds, increasing the severity of pollution. A vortex was produced by southerly winds that led to the convergence of air along the Taihang Mountains. Pollutants were transported from southern–central Hebei Province to Beijing in the boundary layer. Warm advection associated with the southerly winds intensified the inversion produced by the easterly winds and a more stable boundary layer was formed. The layer with high PM_(2.5) concentration became dee-per with persistent southerly winds of a certain depth. The polluted air masses then rose over the northern Taihang Mountains to the northern mountainous regions of Hebei Province. | Zhaobin SUN Xiaoling ZHANG Xiujuan ZHAO Xiangao XIA Shiguang MIAO Ziming LI Zhigang CHENG Wei WEN Yixi TANG | 2018 | Journal of Meteorological Research2018，32，2： | 3 |
| 3 | A New Species of the Genus Trimeresurus from Southwest China(Squamata:Viperidae)显示文摘Species from the Trimeresurus popeiorum complex(Subgenus: Popeia) is a very complex group. T. popeiorum is the only Popeia species known from China. During the past two years, five adult Popeia specimens(4 males, 1 female) were collected from Yingjiang County, Southern Yunnan, China. Molecular, morphological and ecological data show distinct differences from known species, herein we describe these specimens as a new species Trimeresurus yingjiangensis sp. nov Chen, Ding, Shi and Zhang, 2018. Morphologically, the new species distinct from other Popeia species by a combination of following characters:(1) dorsal body olive drab,without cross bands on the scales;(2) a conspicuous bicolor ventrolateral stripe present on each side of males, first row of dorsal scales firebrick with a white ellipse dot on posterior upper part in male, these strips absent in females;(3) eyes firebrick in both gender;(4) suboculars separated from 3rd upper labial by one scale on each side;(5) ventrals 164–168(n = 5);(6) MSR 21. | Zening CHEN Liang ZHANG Jingsong SHI Yezhong TANG Yuhong GUO Zhaobin SONG Li DING | 2019 | Asian Herpetological Research2019，10，1： | 2 |

| 5 | Analysis on the Impacts of Straw Burning on Air Quality in Beijing -Tianjing - Hebei Region显示文摘The beginning of October is the high occurrence period of straw burning in North China and Jianghuai region. Heavy pollution weather caused by straw burning often takes place in recent two years,and thus human factor increases the unpredictability of the air quality forecast. In the early autumn of 2015,a continuous fog-haze weather and heavy air pollution event occurred in North China and Jianghuai region due to the straw burning. In this paper,the effect of straw burning on air quality under the same adverse diffusive meteorological conditions has been analyzed by using the ground and upper air meteorological observation data and air quality monitoring data of Environmental Protection Agency in recent two years. The comparison results show that the basic conditions of heavy pollution are weak wind and the unfavorable diffusion situation. In contrast,relative humidity is the key factor,only 40% of relative humidity during the straw burning can reach heavy pollution level during no straw burning. | Ma Xiaohui Tang Yixi Sun Zhaobin Li Ziming | 2017 | Meteorological and Environmental Research2017，8，5： | 2 |

| 8 | Treatment Effects of Integrated TCM and Western Medicine Treatment Scheme on COVID-19: A Single-armed Clinical Trial显示文摘Backgroud:The outbreak of COVID-19 has brought unprecedented perils to human health and raised public health concerns in more than two hundred countries.Safe and effective treatment scheme is needed urgently.Objective:To evaluate the effects of integratedTCM and western medicine treatment scheme on COVID-19.Methods:A single-armed clinical trial was carried out in Hangzhou Xixi Hospital,an affiliated hospital with Zhejiang Chinese Medical University.102 confirmed cases were screened out from 725 suspected cases and 93 of them were treated with integrated TCM and western medicine treatment scheme.Results:83 cases were cured,5 cases deteriorated,and 5 cases withdrew from the study.No deaths were reported.The mean relief time of fever,cough,diarrhea,and fatigue were(4.78±4.61)days,(7.22±4.99)days,(5.28±3.39)days,and(5.28±3.39)days,respectively.It took(14.84±5.50)days for SARS-CoV-2 by nucleic acid amplification-based testing to turn negative.Multivariable cox regression analysis revealed that age,BMI,PISCT,BPC,AST,CK,BS,and UPRO were independent risk factors for COVID-19 treatment.Conclusion:Our study suggested that integrated TCM and western medicine treatment scheme was effective for COVID-19. | Jianfeng Bao Zhijun Xie Shourong Liu Lin Huang Jing Sun Yujun Tang Haiping Chen Jianjiang Qi Jianchun Guo Liangbin Miao Zhaoyi Li Hui Yang Yi Zhang Zhiyu Li Yuan Xu Shengyou Lin Yunhao Xun Li Zhang Jie Bao Zhaobin Cai Jinsong Huang Chengping Wen | 2021 | Clinical Complementary Medicine and Pharmacology2021，1，1： | 0 |
