| 1 | Guidelines for evaluation and management of cerebral collateral circulation in ischaemic stroke 2017显示文摘Collateral circulation plays a vital role in sustaining blood flow to the ischaemic areas in acute,subacute or chronic phases after an ischaemic stroke or transient ischaemic attack.Good collateral circulation has shown protective effects towards a favourable functional outcome and a lower risk of recurrence in stroke attributed to different aetiologies or undergoing medical or endovascular treatment.Over the past decade,the importance of collateral circulation has attracted more attention and is becoming a hot spot for research.However,the diversity in imaging methods and criteria to evaluate collateral circulation has hindered comparisons of findings from different cohorts and further studies in exploring the clinical relevance of collateral circulation and possible methods to enhance collateral flow.The statement is aimed to update currently available evidence and provide evidence-based recommendations regarding grading methods for collateral circulation,its significance in patients with stroke and methods under investigation to improve collateral flow. | Liping Liu Jing Ding Xinyi Leng Yuehua Pu Li-An Huang Anding Xu Ka Sing Lawrence Wong Xin Wang Yongjun Wang 无 | 2018 | Stroke & Vascular Neurology2018，3，3： | 37 |
| 2 | Can semipermeable membranes coating materials influence in vivo performance for paliperidone tri-layer ascending release osmotic pump tablet:In vitro evaluation and in vivo pharmacokinetics study显示文摘One purpose of this study was to develop a paliperidone(PAL)tri-layer ascending release pushepull osmotic pump(TA-PPOP)tablet which could meet the needs of clinical applications.And another purpose was to investigate whether different coating materials influenced in vivo performance of TA-PPOP.The ascending release mechanism of this trilayer delivery system on theory was elaborated.TA-PPOP was prepared by means of coating with cellulose acetate(CA)or ethyl cellulose(EC).Several important influence factors such as different core tablet compositions and different coating solution ingredients involved in the formulation procedure were investigated.The optimization of formulation and process was conducted by comparing different in vitro release behaviors of PAL.In vitro dissolution studies indicated that both the two formulations of different coating materials were able to deliver PAL at an ascending release rate during the whole 24 h test.The in vivo pharmacokinetics study showed that both self-made PPOP tablets with different coating had a good in vitro-in vivo correlation(IVIVC)and were bioequivalent with the brand product,which demonstrated no significant influence of the coating materials on the in vivo release acceleration of TA-PPOP. | Guangjing Li Yongjun Wang Hongming Chen Donglei Leng Panqin Ma Yanjie Dong Lifang Gao Zhonggui He | 2015 | Asian Journal of Pharmaceutical Sciences2015，10，2： | 4 |

| 6 | Code-Based Preservation Mechanism of Electronic Record in Electronic Record Center of Cloud Storage显示文摘With the rapid development of E-commerce and E-government,there are so many electronic records have been produced.The increasing number of electronic records brings about storage difficulties,the traditional electronic records center is difficult to cope with the current fast growth requirements of electronic records storage and management.Therefore,it is imperative to use cloud storage technology to build electronic record centers.However,electronic records also have weaknesses in the cloud storage environment,and one of them is that once electronic record owners or managers lose physical control of them,the electronic records are more likely to be tampered with and destroyed.So,the paper builds a reliable electronic records preservation system based on coding theory.It can effectively guarantee the reliability of record storage when the electronic record is damaged,and the original electronic record can be restored by redundant coding,thus ensuring the reliable storage of electronic records. | Yan Leng Yongjun Ren Chengshan Qian Jinyue Xia | 2019 | Journal on Big Data2019，1，1： | 0 |
| 7 | Ensuring Readability of Electronic Records Based on Virtualization Technology in Cloud Storage显示文摘With the rapid development of E-commerce and E-government, there are somany electronic records have been produced. The increasing number of electronicrecords brings about storage difficulties, the traditional electronic records center isdifficult to cope with the current fast growth requirements of electronic records storageand management. Therefore, it is imperative to use cloud storage technology to buildelectronic record centers. However, electronic records also have weaknesses in the cloudstorage environment, and one of them is that once electronic record owners or managerslose physical control of them, the electronic records are more likely to be tampered withand destroyed. So, the paper builds a reliable electronic records preservation systembased on coding theory. It can effectively guarantee the reliability of record storage whenthe electronic record is damaged, and the original electronic record can be restored byredundant coding, thus ensuring the reliable storage of electronic records. | Qirun Wang Fujian Zhu Yan Leng Yongjun Ren Jinyue Xia | 2019 | Journal on Internet of Things2019，1，1： | 0 |
