| 1 | Impact of technology advances on China's CO_2 emission reduction显示文摘Global warming tends to be the major characteristics of the dramatic global climate change.To deal with these changes,the impact of reducing greenhouse gas(GHG) emission on Chinese future economic and social development has to be assessed.In this paper,a Regional Integrated model of Climate and the Economy(RICE),which is well known and accepted widely,has been used for Chinese economic assessment of climate change after introduction,assimilation and verification.Based on a sensitivity analysis of technical parameters in the RICE model and constrained targets proposed for energy saving and emissions reduction technological advance programs of China from 2000 to 2050,the economic impact of the programs is examined.The results indicate that when technology advances,Chinese CO2 emission,climate loss,and the growth rate of atmospheric CO2 concentration and temperature will all decrease.It is assumed that in 2010,the CO2 emission is 20% lower than in 2005,CO2 emission in 2050 would only double the level in 2000,the accumulative CO2 emission would be decreased by 12.4 GtC,and the atmospheric CO2 concentration and temperature in 2050 would reduce by 35 GtC and 0.04°C respectively from 2000 to 2050.The accumulative climate loss from 2000 to 2050 will drop down by 4.6 billion dollar,which only accounts for 6% of the global total benefits.However,the economic benefit the developed countries will obtain is 10 times that for China under such a technological advance scenario.The decrease of the CO2 emission control rate is 1% in cooperation policy while 4.6% in non-cooperation policy,which would relieve China's burden in the control of CO2 total emission and thereby benefit China in participation of the international cooperation for CO2 emission reduction. | ZHENG YouFei LI HaiTao WU RongJun WANG LianXi | 2010 | Chinese Science Bulletin2010，55，19： | 4 |
| 2 | Cloud-Base Distribution and Cirrus Properties Based on Micropulse Lidar Measurements at a Site in Southeastern China显示文摘The cloud fraction(CF) and cloud-base heights(CBHs), and cirrus properties, over a site in southeastern China from June 2008 to May 2009, are examined by a ground-based lidar. Results show that clouds occupied the sky 41% of the time.Significant seasonal variations in CF were found with a maximum/minimum during winter/summer and similar magnitudes of CF in spring and autumn. A distinct diurnal cycle in the overall mean CF was seen. Total, daytime, and nighttime annual mean CBHs were 3.05 ± 2.73 km, 2.46 ± 2.08 km, and 3.51 ± 3.07 km, respectively. The lowest/highest CBH occurred around noon/midnight. Cirrus clouds were present ~36.2% of the time at night with the percentage increased in summer and decreased in spring. Annual mean values for cirrus geometrical properties were 8.89 ± 1.65 km, 9.80 ± 1.70 km, 10.73 ± 1.86 km and 1.83 ± 0.91 km for the base, mid-cloud, top height, and the thickness, respectively. Seasonal variations in cirrus geometrical properties show a maximum/minimum in summer/winter for all cirrus geometrical parameters. The mean cirrus lidar ratio for all cirrus cases in our study was ~ 25 ± 17 sr, with a smooth seasonal trend. The cirrus optical depth ranged from 0.001 to 2.475, with a mean of 0.34 ± 0.33. Sub-visual, thin, and dense cirrus were observed in ~12%, 43%, and 45%of the cases, respectively. More frequent, thicker cirrus clouds occurred in summer than in any other season. The properties of cirrus cloud over the site are compared with other lidar-based retrievals of midlatitude cirrus cloud properties. | Jianjun LIU Zhanqing LI ZHENG Youfei Maureen CRIBB | 2015 | Advances in Atmospheric Sciences2015，32，7： | 2 |

| 18 | Melatonin decreases GSDME mediated mesothelial cell pyroptosis and prevents peritoneal fibrosis and ultrafiltration failure显示文摘Peritoneal fibrosis together with increased capillaries is the primary cause of peritoneal dialysis failure.Mesothelial cell loss is an initiating event for peritoneal fibrosis.We find that the elevated glucose concentrations in peritoneal dialysate drive mesothelial cell pyroptosis in a manner dependent on caspase-3 and Gasdermin E,driving downstream inflammatory responses,including the activation of macrophages.Moreover,pyroptosis is associated with elevated vascular endothelial growth factor A and C,two key factors in vascular angiogenesis and lymphatic vessel formation.GSDME deficiency mice are protected from high glucose induced peritoneal fibrosis and ultrafiltration failure.Application of melatonin abrogates mesothelial cell pyroptosis through a MT1R-mediated action,and successfully reduces peritoneal fibrosis and angiogenesis in an animal model while preserving dialysis efficacy.Mechanistically,melatonin treatment maintains mitochondrial integrity in mesothelial cells,meanwhile activating m TOR signaling through an increase in the glycolysis product dihydroxyacetone phosphate.These effects together with quenching free radicals by melatonin help mesothelial cells maintain a relatively stable internal environment in the face of high-glucose stress.Thus,Melatonin treatment holds some promise in preserving mesothelium integrity and in decreasing angiogenesis to protect peritoneum function in patients undergoing peritoneal dialysis. | Hongxia Ruan Xuejuan Li Lina Zhou Zihan Zheng Rulin Hua Xu Wang Yuan Wang Yujie Fan Shuwen Guo Lihua Wang Shafiq ur Rahman Ziwei Wang Yuyuan Wei Shuangyan Yu Rongzhi Zhang Qian Cheng Jie Sheng Xue Li Xiaoyan Liu Ruqiang Yuan Xiaoyan Zhang Lihong Chen Guowang Xu Youfei Guan Jing Nie Hongqiang Qin Feng Zheng | 2024 | Science China(Life Sciences)2024，67，2： | 0 |
