| 1 | Pulmonary embolism with chronic obstructive pulmonary disease显示文摘Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease. The incidence of COPD is growing annually in China, and it is a significant and growing public health burden. Multivariate analysis showed that COPD was one of the independent risk factors for the occurrence of pulmonary embolism (PE),and the incidence of PE was significantly higher in COPD patients than in normal subjects. However, PE is often overlooked in patients with acute exacerbation of COPD (AECOPD) because there are many similarities in clinical symptoms between PE and AECOPD, which are difficult to distinguish, resulting in the failure of timely treatment and poor prognosis. Therefore, it is of great significance to understand the clinical manifestations, diagnosis, and treatment of COPD combined with PE for making a more accurate diagnosis, providing timely and effective treatment, and improving the prognosis of such patients. | Ruohan Yang Guiqing Liu Chaosheng Deng | 2021 | Chronic Diseases and Translational Medicine2021，7，3： | 12 |
| 2 | Health benefits from the rapid reduction in ambient exposure to air pollutants after China’s clean air actions:progress in efficacy and geographic equality显示文摘Clean air actions(CAAs)in China have been linked to considerable benefits in public health.However,whether the beneficial effects of CAAs are equally distributed geographically is unknown.Using high-resolution maps of the distributions of major air pollutants(fine particulate matter[PM_(2.5)]and ozone[O_(3)])and population,we aimed to track spatiotemporal changes in health impacts from,and geographic inequality embedded in,the reduced exposures to PM_(2.5)and O_(3)from 2013 to 2020.We used a method established by the Global Burden of Diseases Study.By analyzing the changes in loss of life expectancy(LLE)attributable to PM_(2.5)and O_(3),we calculated the gain of life expectancy(GLE)to quantify the health benefits of the air-quality improvement.Finally,we assessed the geographic inequality embedded in the GLE using the Gini index(GI).Based on risk assessments of PM_(2.5)and O_(3),during the first stage of CAAs(2013 to 2017),the mean GLE was 1.87 months.Half of the sum of the GLE was disproportionally distributed in about one quarter of the population exposed(GI 0.44).During the second stage of CAAs(2017 to 2020),the mean GLE increased to 3.94 months and geographic inequality decreased(GI 0.18).According to our assessments,CAAs were enhanced,from the first to second stages,in terms of not only preventing premature mortality but also ameliorating health inequalities.The enhancements were related to increased sensitivity to the health effects of air pollution and synergic control of PM_(2.5)and O_(3)levels.Our findings will contribute to optimizing future CAAs. | Tao Xue Ruohan Wang Meng Wang Yanying Wang Dan Tong Xia Meng Conghong Huang Siqi Ai Fangzhou Li Jingyuan Cao Mingkun Tong Xueqiu Ni Hengyi Liu Jianyu Deng Hong Lu Wei Wan Jicheng Gong Shiqiu Zhang Tong Zhu | 2024 | National Science Review2024，11，2： | 0 |
| 3 | The appearance of cytoplasmic cytochrome C precedes apoptosis during Drosophila salivary gland degradation显示文摘Apoptosis is an important process for organism development that functions to eliminate cell damage,maintain homeostasis,and remove obsolete tissues during morphogenesis.In mammals,apoptosis is accompanied by the release of cytochrome C(Cyt-c)from mitochondria to the cytoplasm.However,whether this process is conserved in the fruit fly,Drosophila melanogaster,remains controversial.In this study,we discovered that during the degradation of Drosophila salivary gland,the transcription of mitochondria apoptosis factors(MAPFs),Cyt-c,and death-associated APAF1-related killer(Dark)encoding genes are all upregulated antecedent to initiator and effector caspases encoding genes.The proteins Cyt-c and the active caspase 3 appear gradually in the cytoplasm during salivary gland degradation.Meanwhile,the Cyt-c protein colocates with mito-GFP,the marker indicating cytoplasmic mitochondria,and the change in mitochondrial membrane potential coincides with the appearance of Cyt-c in the cytoplasm.Moreover,impeding or promoting 20E-induced transcription factor E93 suppresses or enhances the staining of Cyt-c and the active caspase 3 in the cytoplasm of salivary gland,and accordingly decreases or increases the mitochondrial membrane potential,respectively.Our research provides evidence that cytoplasmic Cyt-c appears before apoptosis during Drosophila salivary gland degradation,shedding light on partial conserved mechanism in apoptosis between insects and mammals. | Shihui Long Wenxin Cao Yongyu Qiu Ruohan Deng Jiali Liu Lidan Zhang Renke Dong Fengxin Liu Sheng Li Haigang Zhao Na Li Kang Li | 2024 | Insect Science2024，31，1： | 0 |
