| 12 | Global patterns of breast cancer incidence and mortality:A population-based cancer registry data analysis from 2000 to 2020显示文摘Background:Breast cancer is the most commonly diagnosed cancer and leading cause of cancer death among women worldwide but has patterns and trends which vary in different countries.This study aimed to evaluate the global patterns of breast cancer incidence and mortality and analyze its temporal trends for breast cancer prevention and control.Methods:Breast cancer incidence and mortality data in 2020 were obtained from the GLOBOCAN online database.Continued data from the Cancer Incidence in Five Continents Time Trends,the International Agency for Research on cancer mortality and China National Central Cancer Registry were used to analyze the time trends from 2000 to 2015 through Joinpoint regression,and annual average percent changes of breast cancer incidence and mortality were calculated.Association between Human Development Index and breast cancer incidence and mortality were estimated by linear regression.Results:There were approximately 2.3 million new breast cancer cases and 685,000 breast cancer deaths worldwide in 2020.Its incidence and mortality varied among countries,with the age-standardized incidence ranging from the highest of 112.3 per 100,000 population in Belgium to the lowest of 35.8 per 100,000 population in Iran,and the age-standardized mortality from the highest of 41.0 per 100,000 population in Fiji to the lowest of 6.4 per 100,000 population in South Korea.The peak age of breast cancer in some Asian and African countries were over 10 years earlier than in European or American countries.As for the trends of breast cancer,the age-standardized incidence rates significantly increased in China and South Korea but decreased in the United States of America(USA)during 2000-2012.Meanwhile,the age-standardized mortality rates significantly increased in China and South Korea but decreased in the United Kingdom,the USA,and Australia during 2000 and 2015.Conclusions:The global burden of breast cancer is rising fast and varies greatly among countries.The incidence and mortality rates of breast cancer increased rapidly in China and South Korea but decreased in the USA.Increased health awareness,effective prevention strategies,and improved access to medical treatment are extremely important to curb the snowballing breast cancer burden,especially in the most affected countries. | Shaoyuan Lei Rongshou Zheng Siwei Zhang Shaoming Wang Ru Chen Kexin Sun Hongmei Zeng Jiachen Zhou Wenqiang Wei | 2021 | Cancer Communications2021,41,11: | 55 |
| 13 | Chinese expert consensus on cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal malignancies显示文摘Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis(PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery(CRS) + hyperthermic intraperitoneal chemotherapy(HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases Ⅰ, Ⅱ and Ⅲ clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China. | Yan Li Yun-Feng Zhou Han Liang Hua-Qing Wang Ji-Hui Hao Zheng-Gang Zhu De-Seng Wan Lun-Xiu Qin Shu-Zhong Cui Jia-Fu Ji Hui-Mian Xu Shao-Zhong Wei Hong-Bin Xu Tao Suo Shu-Jun Yang Cong-Hua Xie Xiao-Jun Yang Guo-Liang Yang | 2016 | World Journal of Gastroenterology2016,22,30: | 58 |

| 17 | Epalrestat protects against diabetic peripheral neuropathy by alleviating oxidative stress and inhibiting polyol pathway显示文摘Epalrestat is a noncompetitive and reversible aldose reductase inhibitor used for the treatment of diabetic neuropathy. This study assumed that epalrestat had a protective effect on diabetic peripheral nerve injury by suppressing the expression of aldose reductase in peripheral nerves of diabetes mellitus rats. The high-fat and high-carbohydrate model rats were established by intraperitoneal injection of streptozotocin. Peripheral neuropathy occurred in these rats after sustaining high blood glucose for 8 weeks. At 12 weeks after streptozotocin injection, rats were intragastrically administered epalrestat 100 mg/kg daily for 6 weeks. Transmission electron microscope revealed that the injuries to myelinated nerve fibers, non-myelinated nerve fibers and Schwann cells of rat sciatic nerves had reduced compared to rats without epalrestat administuation. Western blot assay and immunohistochemical results demonstrated that after intervention with epalrestat, the activities of antioxidant enzymes such as superoxide dismutase, catalase and glutathione peroxidase gradually increased, but aldose reductase protein expression gradually diminished. Results confirmed that epalrestat could protect against diabetic peripheral neuropathy by relieving oxidative stress and suppressing the polyol pathway. | Qing-rong Li Zhuo Wang Wei Zhou Shou-rui Fan Run Ma Li Xue Lu Yang Ya-shan Li Hong-li Tan Qi, ng-hua Shao Hong-ying Yang | 2016 | Neural Regeneration Research2016,11,2: | 42 |
| 18 | The Sunway TaihuLight supercomputer: system and applications显示文摘The Sunway Taihu Light supercomputer is the world's first system with a peak performance greater than 100 PFlops. In this paper, we provide a detailed introduction to the Taihu Light system. In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators(NVIDIA GPU or Intel Xeon Phi), the computing power of Taihu Light is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements(MPEs)and computing processing elements(CPEs) in one chip. With 260 processing elements in one CPU, a single SW26010 provides a peak performance of over three TFlops. To alleviate the memory bandwidth bottleneck in most applications, each CPE comes with a scratch pad memory, which serves as a user-controlled cache. To support the parallelization of programs on the new many-core architecture, in addition to the basic C/C++and Fortran compilers, the system provides a customized Sunway Open ACC tool that supports the Open ACC2.0 syntax. This paper also reports our preliminary efforts on developing and optimizing applications on the Taihu Light system, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation. | Haohuan FU Junfeng LIAO Jinzhe YANG Lanning WANG Zhenya SONG Xiaomeng HUANG Chao YANG Wei XUE Fangfang LIU Fangli QIAO Wei ZHAO Xunqiang YIN Chaofeng HOU Chenglong ZHANG Wei GE Jian ZHANG Yangang WANG Chunbo ZHOU Guangwen YANG | 2016 | Science China(Information Sciences)2016,59,7: | 45 |

| 20 | Puerarin protects rat brain against ischemia/reperfusion injury by suppressing autophagy via the AMPK-mT OR-ULK1 signaling pathway显示文摘Puerarin suppresses autophagy to alleviate cerebral ischemia/reperfusion injury, and accumulating evidence indicates that the AMPKm TOR signaling pathway regulates the activation of the autophagy pathway through the coordinated phosphorylation of ULK1. In this study, we investigated the mechanisms underlying the neuroprotective effect of puerarin and its role in modulating autophagy via the AMPK-m TOR-ULK1 signaling pathway in the rat middle cerebral artery occlusion model of cerebral ischemia/reperfusion injury. Rats were intraperitoneally injected with puerarin, 50 or 100 mg/kg, daily for 7 days. Then, 30 minutes after the final administration, rats were subjected to transient middle cerebral artery occlusion for 90 minutes. Then, after 24 hours of reperfusion, the Longa score and infarct volume were evaluated in each group. Autophagosome formation was observed by transmission electron microscopy. LC3, Beclin-1 p62, AMPK, m TOR and ULK1 protein expression levels were examined by immunofluorescence and western blot assay. Puerarin substantially reduced the Longa score and infarct volume, and it lessened autophagosome formation in the hippocampal CA1 area following cerebral ischemia/reperfusion injury in a dose-dependent manner. Pretreatment with puerarin(50 or 100 mg/kg) reduced Beclin-1 expression and the LC3-II/LC3-I ratio, as well as p-AMPK and p S317-ULK1 levels. In comparison, it increased p62 expression. Furthermore, puerarin at 100 mg/kg dramatically increased the levels of p-m TOR and p S757-ULK1 in the hippocampus on the ischemic side. Our findings suggest that puerarin alleviates autophagy by activating the APMK-m TOR-ULK1 signaling pathway. Thus, puerarin might have therapeutic potential for treating cerebral ischemia/reperfusion injury. | Jin-Feng Wang Zhi-Gang Mei Yang Fu Song-Bai Yang Shi-Zhong Zhang Wei-Feng Huang Li Xiong Hua-Jun Zhou Wei Tao Zhi-Tao Feng | 2018 | Neural Regeneration Research2018,13,6: | 45 |
