| 1 | Dynamic Response of Phragmites australis and Suaeda salsa to Climate Change in the Liaohe Delta Wetland显示文摘Because of its unique geographical location and ecological function, the Liaohe Delta Wetland is important in maintaining regional ecological balance and security. Monitoring and evaluating changes in the wetland are therefore of great importance. We used medium-and high-resolution satellite data, meteorological station data, and site measurement data to analyze changes in the area and spatial distribution of Phragmites australis and Suaeda salsa in the Liaohe Delta Wetland from 1998 to 2017, as well as their growth response to the climate change. The results showed that during 1998–2017, the areas of both P. australis and S. salsa wetlands alternated through periods of decreasing,increasing, and then decreasing trends. The annual change in the area and spatial distribution range of S. salsa fluctuated more than that of P. australis. The annual variation of normalized difference vegetation index(NDVI) in P. australis wetland showed an upward trend from 1998 to 2017. The area of P. australis cover that was improved, unchanged, and decreased accounted for 81.8%, 12.3%, and 5.9%, respectively, of the total area;evaporation and wind speed were the main meteorological factors affecting the NDVI;and contribution rates of the climate change and human activities to the NDVI were 73.2% and 26.8%, respectively. The area with vegetation cover being mainly S.salsa that was improved, unchanged, and decreased accounted for 63.3%, 18.3%, and 18.4%, respectively, of the total area;and no meteorological factors significantly affected the NDVI of S. salsa in the region. The interaction between vegetation growth and meteorological factors may help to explain the increasing trend in vegetation cover.The improvement in wetland vegetation also led to carbon sequestration and an increase in sequestration capacity. | Yushu ZHANG Wenying YU Ruipeng JI Yijun ZHAO Rui FENG Qingyu JIA Jinwen WU | 2021 | Journal of Meteorological Research2021，35，1： | 3 |

| 3 | Research of combined liver-kidney transplantation model in rats显示文摘Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from porta1 veins to donated 1ivers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment. | Jiageng Zhu Jun Li Ruipeng Jia Jianghao Su Mingshun Shen Zhigang Cao | 2007 | Journal of Nanjing Medical University2007，21，2： | 0 |
| 4 | Establishment of rat model of combined kidney-adrenal gland allotransplantation显示文摘Objective: To establish a rat model of combined kidney-adrenal gland and allotransplantation, and to explore the immunoprotecive effect of the transplanted adrenal gland on the transplanted kidney in the combined transplantation. Methods: SD rats 160 served as donors and recipients. The combined kidney-adrenal gland allotransplantation was performed. Infusion was conducted and prepared at prime position ,and the kidney and adrenal gland were at the left side. Direct vascular anastomosis and operation of connecting ureter attached part of bladder with the bladder were conducted. The kidney pedicle of the right side was ligated. Results: A stable and mature rat model of combined transplantation was established. The warm ischemia time was 30 seconds, and the cold ischemia time was 90-120min.The average time was 100 min. The operation time was 150 min. The survival time of the recipients was 21 days. The successful rate of the operation was 75%. Conclusion: The model of the combined kidney-adrenal gland allotransplantation can be established with higher successful rate. The model can be used to explore that transplanted adrenal gland may have immunoprotecive effect on the transplanted kidney in the combined transplantation. | Yanjun Shi Ruipeng Jia Jiageng Zhu Guangcheng Zhou | 2006 | Journal of Nanjing Medical University2006，20，3： | 0 |
| 5 | Regulation and management of the biosecurity for synthetic biology显示文摘Synthetic biology(SynBio)is a high-profile interdiscipline combining engineering with science.As a dual-purpose discipline,SynBio is bringing large changes to many fields and providing great benefits to humans.However,due to its characteristic of complexity and uncertainty,SynBio also presents potential biosafety and biosecurity risks.Biosecurity risks refer to unauthorized access,loss,theft,misuse,diversion or intentional release.If a biosecurity accident happens,it would pose a huge threat to humans and nature.Therefore,it is crucial to establish a set of regulations and management practices for the biosecurity risks of SynBio.In this paper,we summarized the sources of the biosecurity risks of SynBio,from its research materials,products,technologies,information to Do-it-yourself synthetic biology.We reviewed and analyzed the current situation of regulation and management of biosecurity for SynBio in the international community and in China.We found that in most countries and regions,SynBio risks commonly follow the regulation and management of Genetically Modified Organisms which has loopholes if applied to the regulation for SynBio without any amendments.Here,we proposed suggestions for the Chinese-featured regulation and management of biosecurity for SynBio,including a top-to-bottom governing framework,a think-tank implementation mechanism,a Synthetic Biology Laboratory Biosecurity Manual safeguarding system,and strengthening biosecurity education on synthetic biology and self-regulation awareness among relevant personnel.Through this work,we aim to improve the standardized process of biosecurity regulation and management for SynBio in China and thereby map out a peaceful,profitable,and practical development path for synthetic biology. | Xiaomei Zeng Hailun Jiang Guangying Yang Yakun Ou Shan Lu Jia Jiang Ruipeng Lei Li Su | 2022 | Synthetic and Systems Biotechnology2022，7，2： | 0 |
| 6 | Dynamic regulation of anti-oxidation following donation repairing after circulatory determined death renal transplantation with prolonged non-heart-beating time显示文摘Donation after circulatory-determined death(DCD)is an important part of renal transplantation.Therefore,DCD renal transplantation animal model should be established to study the mechanism of organ injury.Here,we established a stable DCD rat renal transplantation model and investigated the dynamic regulation of graft self-repairing and antioxidant capacities with different non-heart-beating times(NHBTs).Male Sprague-Dawley rats were randomly divided into four groups with the NHBT of the donors from 0 to 15,30,and 45 minutes.Recipients in long NHBT groups had a significantly lower survival rate and poorer graft function than those in short NHBT groups.Grafts from the 15-minute and 30-minute NHBT groups showed light and severe injury respectively at an early stage after transplantation and recovered within 7 days after transplantation,whereas the self-repairing of the grafts in the 45-minute NHBT group was delayed.The expressions of proliferating cell nuclear antigen(PCNA)and von Willebrand factor(vWF)were dependent on NHBT.The expression of antioxidant proteins paralleled graft recovery.In conclusion,the recipients can up-regulate antioxidant capacity to enhance graft self-repairing in DCD renal transplantation.Prolonged NHBT can delay the self-repairing and antioxidation of grafts. | Xinning Wang Changcheng Zhou Jingyu Liu Ruipeng Jia | 2021 | The Journal of Biomedical Research2021，35，5： | 0 |
