| 1 | Trend of declining stroke mortality in China:reasons and analysis显示文摘Introduction There is a downward trend of stroke-related mortality in the USA.By reviewing all published articles on stroke mortality in China,we analysed its trend and possible factors that have influenced the trend.Methods Both English and Chinese literatures were searched on the mortality of stroke or cerebrovascular diseases in China.Potential papers related to this topic were identified from PubMed,Medline,Embase,Cochrane Library,Wanfang Database,SINOMED and China National Knowledge Infrastructure databases.Results Comparing the results from the most recent population-based epidemiological survey and databank from the national Center for Disease Control and Prevention,the age-adjusted stroke mortality rate has shown a downward trend among both urban and rural population in the past 30 years in China.Comparing with 30 years ago,the rate of stroke mortality has decreased by more than 31%in urban/suburban population and 11%in rural population.In men,the age-adjusted stroke mortality rate decreased by 18.9%and in women by 24.9%between 1994 and 2013.Factors that may have contributed to the trend of decreased stroke mortality rate include(1)improved healthcare coverage and healthcare environment;(2)improved treatment options and medical technology;(3)support by government to educate the public on stroke and stroke prevention;and(4)improved public knowledge on stroke.Conclusions The age-adjusted stroke mortality rate in China has shown a downward trend among both urban and rural population in the past 30 years.The major influencing factors that helped in reducing stroke mortality in China included improved healthcare coverage,healthcare environment,the updated treatment options and modern medical technology. | Wenzhi Wang David Wang Hongmei Liu Haixin Sun Bin Jiang Xiaojuan Ru Dongling Sun Zhenghong Chen Yongjun Wang | 2017 | Stroke & Vascular Neurology2017，2，3： | 52 |
| 2 | Breast cancer incidence and mortality in women in China: temporal trends and projections to 2030显示文摘Objective:Breast cancer was the most common cancer and the fifth cause of cancer deaths among women in China in 2015.The evaluation of the long-term incidence and mortality trends and the prediction of the future burden of breast cancer could provide valuable information for developing prevention and control strategies.Methods:The burden of breast cancer in China in 2015 was estimated by using qualified data from 368 cancer registries from the National Central Cancer Registry.Incident cases and deaths in 22 cancer registries were used to assess the time trends from 2000 to 2015.A Bayesian age-period-cohort model was used to project the burden of breast cancer to 2030.Results:Approximately 303,600 new cases of breast cancer(205,100 from urban areas and 98,500 from rural areas)and 70,400 breast cancer deaths(45,100 from urban areas and 24,500 from rural areas)occurred in China in 2015.Urban regions of China had the highest incidence and mortality rates.The most common histological subtype of breast cancer was invasive ductal carcinoma,followed by invasive lobular carcinoma.The age-standardized incidence and mortality rates increased by 3.3%and 1.0%per year during 2000–2015,and were projected to increase by more than 11%until 2030.Changes in risk and demographic factors between 2015 and 2030 in cases are predicted to increase by approximately 13.3%and 22.9%,whereas deaths are predicted to increase by 13.1%and 40.9%,respectively.Conclusions:The incidence and mortality of breast cancer continue to increase in China.There are no signs that this trend will stop by 2030,particularly in rural areas.Effective breast cancer prevention strategies are therefore urgently needed in China. | Shaoyuan Lei Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Hongmei Zeng Wenqiang Wei Jie He | 2021 | Cancer Biology & Medicine2021，18，3： | 53 |
| 3 | 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 |
| 4 | Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF. | Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun | 2018 | Science China(Life Sciences)2018，61，12： | 43 |
| 5 | Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS. | Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu | 2017 | Science China(Life Sciences)2017，60，4： | 39 |
| 6 | Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China. | Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei | 2021 | Chinese Journal of Cancer Research2021，33，1： | 16 |
| 7 | Cancer statistics in Chinese older people,2022:current burden,time trends,and comparisons with the US,Japan,and the Republic of Korea显示文摘Largely due to population ageing,the cancer burden from older people has been rising,which imposed considerable pressure on current Chinese healthcare system.We provide comprehensive information about cancer burden of Chinese older people based on the most recent data from National Central Cancer Registry of China.The logarithmic linear regression was used to project the current cancer burden in 2022,and Joinpoint regression was used for temporal trend analysis from 2000 to 2017.We also estimated cancer statistics of older people in the US,Japan and the Republic of Korea for comparisons.It is estimated that 2.79 million cases and 1.94 million deaths occur for Chinese older people,representing 55.8%and 68.2%of cases and deaths in all population in 2022.The overall cancer incidence rate gradually increased among older women,while the mortality rates declined for both sexes.Notably,approximately 10.0%of all cases and 17.7%of all deaths are from people aged over 80 years,and cancer incidence and mortality in this age group showed upward trends for women.Lung cancer and digestive cancers are the leading cancer types for Chinese older people.Compared with other countries,China has lower incidence rates but higher mortality rates for older people.The rapidly growing burden of prostate cancer,breast cancer,colorectal cancer,and declines in esophageal cancer,stomach cancer,and liver cancer among older people indicate the cancer pattern in China is being in a transition stage to that in developed countries.Our findings imply that it should be the national health priority to meet the growing demands for cancer diagnosis,treatment and care services from the older people as the rapid population ageing in next few decades. | Wen Ju Rongshou Zheng Siwei Zhang Hongmei Zeng Kexin Sun Shaoming Wang Ru Chen Li Li Wenqiang Wei Jie He | 2023 | Science China(Life Sciences)2023，66，5： | 15 |
| 8 | Chinese Stroke Association guidelines for clinical management of cerebrovascular disorders:executive summary and 2019 update of the management of high-risk population显示文摘Aim Cerebrovascular disease is the leading cause of death and disability in China,causing a huge burden among patients and their families.Hence,stroke prevention is critical,especially in the high-risk population.Here,we present the evidence-based guideline suitable for the Chinese population.Methods Literature search of PubMed and Cochrane library(from January 1964 to June 2019)was done.After thorough discussion among the writing group members,recommendations were listed and summarised.This guideline was reviewed and discussed by the fellow writing committees of the Chinese Stroke Association’s Stroke.Results This evidence-based guideline was written in three parts:controlling the risk factors of stroke,utilisation of antiplatelet agents and assessing the risks of first-ever stroke.All recommendations were listed along with the recommending classes and levels of evidence.Conclusions This guideline provides recommendations for primary prevention of cerebrovascular disease among high-risk population in China.Controlling related risk factors,appropriately using antiplatelet agents,assessing the risk of developing first-ever stroke should help reduce the rate of cerebrovascular disease in China. | Yilong Wang Shangrong Han Haiqiang Qin Huaguang Zheng Bin Jiang Yong Cao Yuan Gao Ling Guan Qian Jia Yong Jiang Yuming Jiao Shuya Li Yapeng Li Zixiao Li Wei Liu Xiaojuan Ru Dongling Sun Haixin Sun Penglian Wang Tingting Wang Lixia Zong Lei Guo Xuewei Xie Yuming Xu Yuyuan Xu Xiaomeng Yang Yingying Yang Mengyuan Zhou Wenzhi Wang Chinese Stroke Association Stroke Council Guideline Writing Committee | 2020 | Stroke & Vascular Neurology2020，5，3： | 11 |

| 10 | Local concentration of middle and heavy rare earth elements in the col on the weathered crust elution-deposited rare earth ores显示文摘This present study focused on investigating the content and relative enrichment multiple of rare earth elements(REEs) in different terrain of weathered ore body, and the value of light rare earth elements/middle and heavy rare earth elements(LREEs/HREEs), in order to understand the mobilization and redistribution of HREEs, Furthermore, the abrasion pH was investigated as well, The results show that the average contents of HREEs in the knap, ridge and col are 37.26, 61.71, and 271.3 μg/g, respectively. The value of LREEs/HREEs is decreased from 16.78 to 7.914 between knap and col and the relative enrichment multiple of HREEs is as follows: C_(Col-HREEs) > C_(Ridge-HREEs) > 0. It is indicated the HREEs is concentrated in the col and the enrichment degree of HREEs is stronger than the ridge and the knap. Rare earth elements fractionation is exhibited in the different terrain of weathered ore body. Based on this study, the finding that HREEs concentrate in the lower terrain of weathered crust elution-deposited rare earth ores, such as in the col, would become a marker or indicator to search for middle and heavy rare earth enriched zone. | Zhenyue Zhang Ningjie Sun Zhengyan He Ru'an Chi | 2018 | Journal of Rare Earths2018，36，5： | 10 |
| 11 | Regional path moving horizon tracking controller design for autonomous ground vehicles显示文摘A novel regional path tracking description is presented in this manuscript, and the moving horizon control method that is model predictive control(MPC) is proposed to discuss the regional path tracking issue which could avoid colliding road boundary when tracking a more complex road effectively. The feasible region for autonomous ground vehicles(AGVs) running is determined first according to the detected road boundaries.Then, in order to keep the actual trajectory of AGVs in the region and satisfy the safety requirements, MPC method is employed to design the path tracking controller considering actuator and road boundary constraints.In order to verify the effectiveness of the proposed method, experiments based on Hongqi AGV HQ430 are carried out, and the results illustrate that the presented method could be successfully applied to Hongqi AGV vehicle HQ 430. | Hongyan GUO Feng LIU Ru YU Zhenping SUN Hong CHEN | 2017 | Science China(Information Sciences)2017，60，1： | 9 |
| 12 | Clinical deep remission and related factors in a large cohort of patients with rheumatoid arthritis显示文摘Background:Clinical remission is the treatment target in rheumatoid arthritis (RA).This study aimed to investigate clinical remission and related factors in a large cohort of patients with RA.Methods:This study composed of 342 patients with RA.Data were collected by face-to-face interview of 1049 patients with RA who visited the Department of Rheumatology of three teaching hospitals from September 2015 to May 2016.The patients with RA were clinically assessed by rheumatologists and a four-page questionnaire was completed on site.Subsequently,patients fulfilled remission criteria were further analyzed.The practicability of different definitions of remission of RA was rated by a panel of rheumatologists.Sustained intensive disease modifying anti-rheumatic drug (DMARD) treatment was defined as a combination treatment with two or more DMARDs for at least 6 months.Results:In this cohort of 342 patients with RA,the proportions of patients achieving remission were 38.0%,29.5%,24.9%,21.1%,19.0%,18.1%,and 17.0%,based on criteria of disease activity score in 28 joints (DAS28) using CRP (DAS28-CRP),DAS28 using ESR (DAS28-ESR),routine assessment of patient index data 3 (RAPID-3),Boolean,simplified disease activity index (SDAI),clinical disease activity index,and the newly described clinical deep remission (CliDR),respectively.Boolean and CliDR are the best in practicability scored by rheumatologists (7.5 and 8.0,respectively).Compared with the non-sustained intensive group,sustained intensive treatment with DMARDs yielded higher remission rates of 25.6%,23.8%,and 21.3% in patients with RA based on Boolean (χ^2=3.937,P=0.047),SDAI (χ^2=4.666,P=0.031),and CliDR criteria (χ^2=4.297,P=0.038).The most commonly prescribed conventional synthesized DMARDs (csDMARDs) in patients with RA was leflunomide,followed by methotrexate,and hydroxychloroquine.Compared with the non-remission group,patients achieving remission had a longer median duration of DMARDs (45.0 [22.8–72.3] months,Z=-2.295,P=0.022).Conclusions:The findings in this study indicated that clinical deep remission is achievable in patients with RA.Sustained intensive DMARD treatment is needed to achieve a better outcome in RA. | Jia-Jia Liu Ru Li Yu-Zhou Gan Rui-Jun Zhang Jing Li Yue-Ming Cai Jin-Xia Zhao Hua Liao Jing Xu Lian-Jie Shi Ji Li Sheng-Guang Li Xiao-Lin Sun Jing He Xu Liu Hua Ye Zhan-Guo Li | 2019 | Chinese Medical Journal2019，，9： | 7 |
| 13 | Efficacy and safety of low-dose interleukin-2 in combination with methotrexate in patients with active rheumatoid arthritis:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Rheumatoid arthritis(RA)is an aggressive autoimmune arthritis,and current therapies remain unsatisfactory due to low remission rate and substantially adverse effects.Low-dose interleukin-2(Ld-IL2)is potentially a therapeutic approach to further improve the disease.This randomized,double-blind,placebo-controlled trial was undertaken to evaluate the efficacy and safety of Ld-IL2 in patients with active RA.Patients were randomly assigned(1:1)to receive Ld-IL2,defined as a dose of 1 million IU,or placebo in a 12-week trial with a 12-week follow-up.Three cycles of Ld-IL2 or placebo were administered subcutaneously every other day for 2 weeks(a total of 7 doses),followed by a 2-week break.All patients received a stable dose of methotrexate(MTX).The primary outcomes were the proportion of patients achieving the ACR20,DAS28-ESR<2.6,and the change from baseline in CDAI or SDAI at week 24.Secondary endpoints included other clinical responses and safety.The primary outcomes were achieved in the perprotocol population.The improvements from baseline in CDAI and SDAI were significantly greater across time points for the LdIL2+MTX group(n=17)than for the placebo+MTX group(n=23)(P=0.018 and P=0.015,respectively).More patients achieved ACR20 response in the Ld-IL2+MTX group than those in the placebo+MTX group at week 12(70.6%vs 43.5%)and at week 24(76.5%vs 56.5%)(P=0.014).In addition,low Treg and high IL-21 were associated with good responses to Ld-IL2.Ld-IL-2 treatment was well-tolerated in this study.These results suggested that Ld-IL2 was effective and safe in RA.ClinicalTrials.gov number:NCT 02467504. | Xiaoying Zhang Miao Miao Ruijun Zhang Xu Liu Xiaozhen Zhao Miao Shao Tian Liu Yuebo Jin Jiali Chen Huixin Liu Xia Zhang Yun Li Yunshan Zhou Yue Yang Ru Li Haihong Yao Yanying Liu Chun Li Yuhui Li Limin Ren Yin Su Xiaolin Sun Jing He Zhanguo Li | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 7 |
| 14 | Distribution and Ecological Risk Assessment of HCHs and DDTs in Surface Seawater and Sediment of the Mariculture Area of Jincheng Bay,China显示文摘The distribution of hexachlorocyclohexanes(HCHs) and dichlorodiphenyltrichloroethanes(DDTs) in the surface seawater and sediment of Jincheng Bay mariculture area were investigated in the present study. The concentration of total HCHs and DDTs ranged from 2.98 to 14.87 ng L-1 and were < 0.032 ng L-1, respectively, in surface seawater, and ranged from 5.52 to 9.43 and from 4.11 to 6.72 ng g-1, respectively, in surface sediment. It was deduced from the composition profile of HCH isomers and DDT congeners that HCH residues derived from a mixture of technical-grade HCH and lindane whereas the DDT residues derived from technical-grade DDT and dicofol. Moreover, both HCH and DDT residues may mainly originate from historical inputs. The hazard quotient of α-HCH, β-HCH, γ-HCH and δ-HCH to marine species was 0.030, 0.157, 3.008 and 0.008, respectively. It was estimated that the overall probability of adverse biological effect from HCHs was less than 5%, indicating that its risk to seawater column species was low. The threshold effect concentration exceeding frequency of γ-HCH, p,p'-DDD, p,p'-DDE and p,p'-DDT in sediment ranged from 8.3% to 100%, and the relative concentration of the HCH and DDT mixture exceeded their probable effect level in sediment. These findings indicated that the risk to marine benthos was high and potentially detrimental to the safety of aquatic products, e.g., sea cucumber and benthic shellfish. | HU Yanbing SUN Shan SONG Xiukai MA Jianxin RU Shaoguo | 2015 | Journal of Ocean University of China2015，14，2： | 7 |
| 15 | Effects of Bushen Yiqi Huoxue Decoction in Treatment of Patients with Diminished Ovarian Reserve:A Randomized Controlled Trial显示文摘Objective:To explore the therapeutic effect of Bushen Yiqi Huoxue Decoction BYHD)in patients with diminished ovarian reserve(DOR).Methods:A total of 180 patients with DOR diagnosed from December2013 to December 2014 were equally assigned into progynova and duphaston(E+D)group,Zuogui Pill group and BYHD group with 60 cases in each by computerized randomization.Patients received E+D,Zuogui Pill or BYHD for 12 months,respectively.Follicle stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E_(2)),anti-Mullerian hormone(AMH),antral follicle count(AFC),ovarian volume,endometrial thickness,and the resistance indices(Rls)of ovarian arteries and uterine arteries were observed before and after treatment.Results:Nine women(4 from the E+D group,3 from the Zuogui Pill group,and 2 from the BYHD group)withdrew from the study.After 6 months,Zuogui Pill and BYHD significantly decreased FSH and LH and increased endometrial thickness and AMH(all P<0.01),BYHD also resulted in E2 elevation(P<0.05),ovary enlargement(P<0.05),AFC increase(P<0.01),and RI of ovarian arteries decrease(P<0.05).After 12 months,further improvements were observed in the Zuogui Pill and BYHD groups(all P<0.01),but BYHD showed better outcomes,with lower FSH,larger ovaries and a thicker endometrium compared with the Zuogui Pill group(all P<0.01).However,E+D only significantly increased endometrial thickness(P<0.01)and no significant improvements were observed in the RI of uterine arteries in the three groups.Conclusions:BYHD had a favorable therapeutic effect in patients with DOR by rebalancing hormone levels,promoting ovulation,and repairing the thin endometrium.The combination of tonifying Shen(Kidney),benefiting qi and activating blood circulation may be a promising therapeutic strategy for DOR. | ZHOU Jing PAN Xin-yao LIN Jin ZHOU Qi LAN Li-kun ZHU Jun DUAN Ru WANG Lan SUN Yan WANG Ling | 2022 | Chinese Journal of Integrative Medicine2022，28，3： | 7 |
| 16 | Surrogate production of genome-edited sperm from a different subfamily by spermatogonial stem cell transplantation显示文摘The surrogate reproduction technique,such as inter-specific spermatogonial stem cells(SSCs)transplantation(SSCT),provides a powerful tool for production of gametes derived from endangered species or those with desirable traits.However,generation of genome-edited gametes from a different species or production of gametes from a phylogenetically distant species such as from a different subfamily,by SSCT,has not succeeded.Here,using two small cyprinid fishes from different subfamilies,Chinese rare minnow(gobiocypris rarus,for brief:Gr)and zebrafish(danio rerio),we successfully obtained Gr-derived genome-edited sperm in zebrafish by an optimized SSCT procedure.The transplanted Gr SSCs supported the host gonadal development and underwent normal spermatogenesis,resulting in a reconstructed fertile testis containing Gr spermatids and zebrafish testicular somatic cells.Interestingly,the surrogate spermatozoa resembled those of host zebrafish but not donor Gr in morphology and swimming behavior.When pou5f3 and chd knockout Gr SSCs were transplanted,Gr-derived genome-edited sperm was successfully produced in zebrafish.This is the first report demonstrating surrogate production of gametes from a different subfamily by SSCT,and surrogate production of genome-edited gametes from another species as well.This method is feasible to be applied to future breeding of commercial fish and livestock. | Fenghua Zhang Yongkang Hao Xianmei Li Yi Li Ding Ye Ru Zhang Xiaosi Wang Mudan He Houpeng Wang Zuoyan Zhu Yonghua Sun | 2022 | Science China(Life Sciences)2022，65，5： | 7 |
| 17 | Endocrine Disruption Activity of 30-day Dietary Exposure to Decabromodiphenyl Ethane in Balb/C Mouse显示文摘Objective This study aimed to evaluate the hepatotoxicity,metabolic disturbance activity and endocrine disrupting activity of mice treated by Decabromodiphenyl ethane(DBDPE).Methods In this study,Balb/C mice were treated orally by gavage with various doses of DBDPE.After 30 days of treatment,mice were sacrificed; blood,livers and thyroid glands were obtained,and hepatic microsomes were isolated.Biochemical parameters including 8 clinical chemistry parameters,blood glucose and hormone levels including insulin and thyroid hormone were assayed.The effects of DBDPE on hepatic cytochrome P450(CYP) levels and activities and uridinediphosphate-glucuronosyltransferase(UDPGT) activities were investigated.Liver and thyroid glands were observed.Results There were no obvious signs of toxicity and no significant treatment effect on body weight,or liver-to-body weight ratios between treatment groups.The levels of ALT and AST of higher dose treatment groups were markedly increased.Blood glucose levels of treatment groups were higher than those of control group.There was also an induction in TSH,T3,and f T3.UDPGT,PROD,and EROD activities were found to have been increased significantly in the high dose group.Histopathologic liver changes were characterized by hepatocyte hypertrophy and cytoplasmic vacuolization.Our findings suggest that DBDPE can cause a certain degree of mouse liver damage and insufficiency.Conclusion DBDPE has the activity of endocrine disruptors in Bal/C mice,which may induce drug-metabolizing enzymes including CYPs and UDPGT,and interfere with thyroid hormone levels mediated by Ah R and CAR signaling pathways.Endocrine disrupting activity of DBDPE could also affect the glucose metabolism homeostasis. | SUN Ru Bao SHANG Shuai ZHANG Wei LIN Ben Cheng WANG Qiang SHI Yun XI Zhu Ge | 2018 | Biomedical and Environmental Sciences2018，31，1： | 7 |
| 18 | Simultaneous quantification of ginsenoside Rg1 and its metabolites by HPLC–MS/MS:Rg1 excretion in rat bile, urine and feces显示文摘Ginsenoside Rg1(Rg1), the major effective component of ginseng, has been shown to have multiple bioactivities, but low oral bioavailability. The aim of this study was to develop a simple, sensitive and rapid high performance liquid chromatography–tandem mass spectrometry(LC–MS/MS) method, which could be used to validate and quantify the concentrations of Rg1 and its metabolites in Sprague-Dawley rat bile,urine, and feces after oral administration(25 mg/kg). Calibration curves offered satisfactory linearity(r40.995)within the determined ranges. Both intra-day and inter-day variances were less than 15%, and the accuracy was within 80–120%. The excretion recoveries of Rg1, ginsenoside Rh1(Rh1), and protopanaxatriol(Ppt) in bile,urine, and feces combined were all greater than 70%. The fecal excretion recoveries of Rg1, Rh1, and Ppt were40.11%, 22.19%, and 22.88%, respectively, whereas 6.88% of Rg1 and 0.09% of Rh1 were excreted in bile.Urinary excretion accounted for only 0.04% of Rg1. In conclusion, the observed excretion profiles for Rg1 and its metabolites after oral administration are helpful for understanding the poor oral bioavailability of Rg1 and will aid further investigations of Rg1 as a pharmacologically active component. | Chiyu He Ru Feng Yupeng Sun Shifeng Chu Ji Chen Chao Ma Jie Fu Zhenxiong Zhao Min Huang Jiawen Shou Xiaoyang Li Yuzhu Wang Jinfeng Hu Yan Wang Juntian Zhang | 2016 | Acta Pharmaceutica Sinica B2016，6，6： | 6 |
| 19 | Effects of d-Phenylalanine as a biocide enhancer of THPS against the microbiologically influenced corrosion of C1018 carbon steel显示文摘Microbiologically influenced corrosion(MIC) is caused by biofilms such as those of sulfate reducing bacteria(SRB). To mitigate MIC, biocide treatment is often needed. Tetrakis(hydroxymethyl) phosphonium sulfate(THPS) is an environmentally friendly biocide that is often used in the oil and gas industry. However, its prolonged use leads to biocide resistance, leading to dosage escalation. A biocide enhancer can be used to slow down the trend. In recent years, d-amino acids have been investigated as an enhancer for THPS and other biocides. Published works used anaerobic vials and flow devices, which could not reveal the real-time changes of the biocide treatment on corrosion. In this work, it was proven that the biocide enhancement effects of d-Phenylalanine(d-Phe) on THPS against the Desulfovibrio vulgaris biofilm on C1018 carbon steels could be assessed in real time using linear polarization resistance and electrochemical impedance spectroscopy to collaborate sessile cell count, weight loss and pitting depth data. The results showed that 500 ppm(w/w) d-Phe effectively enhanced 80 ppm THPS against MIC by the D. vulgaris(a corrosive SRB) biofilm. The sessile cell count and pit depth were all reduced with the enhancement of d-Phe. | Jin Xu Ru Jia Dongqing Yang Cheng Sun Tingyue Gu | 2019 | Journal of Materials Science & Technology2019，35，1： | 6 |
| 20 | Cytotoxicity and Apoptosis Induction in Human HepG2 Hepatoma Cells by Decabromodiphenyl Ethane显示文摘Objective To investigate the toxic effects of decabromodiphenyl ethane (DBDPE), used as an alternative to decabromodiphenyl ether in vitro. Methods HepG2 cells were cultured in the presence of DBDPE at various concentrations (3.125-100.0 mg/L) for 24, 48, and 72 h respectively and the toxic effect of DBDPE was studied. Results As evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and lactate dehydrogenase assays and nuclear morphological changes, DBDPE inhibited HepG2 viability in a time- and dose-dependent manner within a range of 12.5 mg/L to 100 mg/L and for 48 h and 72 h. Induction of apoptosis was detected at 12.5-100 mg/L at 48 h and 72 h by propidium iodide staining, accompanied with overproduction of reactive oxygen species (ROS). Furthermore, N-acetyl-L-cysteine, a widely used ROS scavenger, significantly reduced DBDPE-induced ROS levels and increased HepG2 cells viability. Conclusion DBDPE has cytotoxic and anti-proliferation effect and can induce apoptosis in which ROS plays an important | SUN Ru Bao XI Zhu Ge YAN Jun YANG Hong Lian | 2012 | Biomedical and Environmental Sciences2012，25，5： | 6 |
