| 1 | Research on trusted computing and its development显示文摘Trusted computing is a novel technology of information system security. It has become a new tide in worldwide information security area and achieved inspiring accomplishment. In China, the initiative research of trusted computing is not late, and the achievements are plentiful and substantial. Our country is in the front rank of the world in trusted computing. This paper comprehensively illustrates the recent development in theory and technology of trusted computing, introduces some improvements in trusted computing in our country, and proposes our opinions and viewpoints towards the existing problems in trusted computing and its future development. | SHEN ChangXiang ZHANG HuanGuo WANG HuaiMin WANG Ji ZHAO Bo YAN Fei YU FaJiang ZHANG LiQiang XU MingDi | 2010 | Science China(Information Sciences)2010，53，3： | 37 |
| 2 | Effect of manual acupuncture on bowel motility in normal kunming mouse显示文摘OBJECTIVE:To observe the effects of acupuncture on motility of jejunum and distal colon at different acupoints on normal Kunming mice.METHODS:The jejunal and colorectal motor activity of forty Kunming mice were recorded by the intra-intestinal capsule.The capsules contained with distilled water were placed into the cavities of jejunum and distal colon.The changes of bowel were compared with the background activity recorded before any stimulation.The chosen acupoints were as follows:Zusanli(ST 36) on the lower legs,Tianshu(ST 25) on the mid-lower abdomen.RESULTS:Manual acupuncture(MA) at Zusanli(ST36) significantly promoted the motility of jejunum and distal colon(manifested as increased change rate of average amplitude and increased change rate of mean area under the contractile curve) of normal Kunming mice(P < 0.01).MA atTianshu(ST25) significantly inhibited the motility of jejunum(manifested as decreased change rate of average amplitude,decreased change rate of mean area under the contractile curve,and the reduced frequency) of normal Kunming mice(P < 0.01),while significantly increased the distal colonic motility(manifested as increased amplitude and increased mean area under the contractile curve) of normal Kunming mice(P < 0.01).CONCLUSION:MA at specific acupoints[Zusanli(ST 36),Tianshu(ST 25)]has different effects on the motility of jejunum and distal colon,which might involve the segmental innervations of the related nerve. | Zhao Yuxue Cui Changxiang Qin Qingguang Ben Hui Gao Junhong Yu Xiaochun Zhu Bing | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 5 |
| 3 | Formal Compatibility Model for Trusted Computing Applications显示文摘The Chinese specification for trusted computing, which has similar functions with those defined by the Trusted Computing Group (TCG), has adopted a different cryptography scheme. Applications designed for the TCG specifications cannot directly function on platforms complying with Chinese specifications because the two cryptography schemes are not compatible with each other. In order to transplant those applications with little to no modification, the paper presents a formal compatibility model based on Zaremski and Wing’s type system. Our model is concerned not only on the syntactic compatibility for data type, but also on the semantic compatibility for cryptographic attributes according to the feature of trusted computing. A compatibility algorithm is proposed based on the model to generate adapters for trusted computing applications. | ZHU Lu YU Sheng ZHANG Xing SHEN Changxiang | 2009 | Wuhan University Journal of Natural Sciences2009，14，5： | 2 |
| 4 | Mg(OH)_(2)nanosheets on Ti with immunomodulatory function for orthopedic applications显示文摘Macrophages play a vital role for guiding the fate of osteogenesisrelated cells.It is well known that nano-topography and bioactive ions can directly enhance osteogenic behavior.However,the effects of nano-structure combined with bioactive ions release on macrophage polarization and the following osteogenesis and angiogenesis are rarely reported.Herein,Mg(OH)_(2)films with nano-sheet structures were constructed on the surface of Ti using hydrothermal treatment.The film presented nanosheet topography and sustained release of Mg ions.The results of in vitro culture of bone marrow-derived macrophages(BMDMs),including PCR,western blot and flow cytometry suggested that the nano-Mg(OH)_(2)films were more favorable for macrophages polarizing to tissue healing M2 phenotype.Moreover,air-pouch model confirmed that the nano-Mg(OH)_(2)film coated Ti would induce milder inflammation and thinner fibrous layer in vivo,compared with untreated Ti.Furthermore,macrophages-conditioned culture mediums were collected from nano-Mg(OH)_(2)coated Ti group was superior for the osteogenic behaviors of mice bone marrow stem cells and the angiogenic behaviors of human umbilical vein endothelial cells.With harmonious early inflammatory response and subsequently improved osteogenesis and angiogenesis,the nano-Mg(OH)_(2)coated Ti is promising for orthopedic applications. | Yue He Mengyu Yao Jielong Zhou Juning Xie Changxiang Liang Dong Yin Shuaihao Huang Yu Zhang Feng Peng Shi Cheng | 2022 | Regenerative Biomaterials2022，9，1： | 1 |
| 5 | Biological characteristics of brain natriuretic peptide and its association with central nervous system diseases显示文摘OBJECTIVE: To explain the mechanisms of tuhe synthesis, secretion and regulation of brain natriuretic peptide (BNP), and analyze its role in central nervous system diseases. DATA SOURCES: An online search of Pubmed was undertaken to identify articles related to BNP published in English from January 1990 to February 2007 by using the of 'brain natriuretic peptide (BNP), central nervous system, subarachnoid hemorrhage (SAH), brain edema, epilepsy'. Other articles were searched in China Hospital Knowledge Database (CHKD) by concrete name of journals and title of articles. STUDY SELECTION: The collected articles were primarily screened, those about BNP and its association with central nervous system diseases were selected, whereas the obviously irrelative ones excluded, and the full-texts of the other literatures were searched manually. DATA EXTRACTION: Totally 96 articles were collected, 40 of them were enrolled, and the other 56 were excluded due to repetitive studies or reviews. DATA SYNTHESIS: At present, there are penetrating studies on BNP in the preclinical medicine and clinical medicine of cerebrovascular and cardiovascular diseases, and the investigative outcomes have been gradually applied in clinical practice, and satisfactory results have been obtained. However, the application of BNP in diagnosing and treating central nervous system diseases is still at the experimental phase without - outstanding outcomes, thus the preclinical and clinical studies should be enhanced. CONCLUSION: As a kind of central medium or modulator, BNP plays a certain role in the occurrence, development and termination of central nervous system diseases, the BNP level in serum has certain changing law in SAH, brain edema, epilepsy, etc., but the specific mechanisms are unclear. | Yubao Huang Changxiang Yan Chunjiang Yu | 2007 | Neural Regeneration Research2007，2，3： | 0 |
| 6 | Phytoestrogen-derived multifunctional ligands for targeted therapy of breast cancer显示文摘Nano-targeted delivery systems have been widely used for breast tumor drug delivery.Estrogen receptors are considered to be significant drug delivery target receptors due to their overexpression in a variety of tumor cells.However,targeted ligands have a significant impact on the safety and effectiveness of active delivery systems,limiting the clinical transformation of nanoparticles.Phytoestrogens have shown good biosafety characteristics and some affinity with the estrogen receptor.In the present study,molecular docking was used to select tanshinone IIA(Tan IIA)among phytoestrogens as a target ligand to be used in nanodelivery systems with somemodifications.Modified Tan IIA(Tan-NH2)showed a good biosafety profile and demonstrated tumor-targeting,anti-tumor and anti-tumor metastasis effects.Moreover,the ligand was utilized with the anti-tumor drug Dox-loaded mesoporous silica nanoparticles via chemical modification to generate a nanocomposite Tan-Dox-MSN.Tan-Dox-MSN had a uniform particle size,good dispersibility and high drug loading capacity.Validation experiments in vivo and in vitro showed that it also had a better targeting ability,anti-tumor effect and lower toxicity in normal organs.These results supported the idea that phytoestrogens with high affinity for the estrogen receptor could improve the therapeutic efficacy of nano-targeted delivery systems in breast tumors. | Ying Zhang Hao Pan Changxiang Yu Rui Liu Bin Xing Bei Jia Jiachen He Xintao Jia Xiaojiao Feng Qingqing Zhang Wenli Dang Zheming Hu Xiuping Deng Pan Guo Zhidong Liu Weisan Pan | 2023 | Asian Journal of Pharmaceutical Sciences2023，18，4： | 0 |
