| 1 | SIMO含公零点信道的直接盲序列检测显示文摘本文首先在BPSK字符集下提出了与经典迫零均衡有本质不同的ε均衡概念,给出了ε均衡器存在的充分必要条件.然后,本文借助接收数据阵补投影算子对待测发送序列向量的零化作用,把BPSK信号盲检测问题转化为带二值约束的二次规划问题.最后,通过复数量重新定义成实数量,本文把上述的ε均衡概念和盲检测算法成功地推广应用于QPSK复信道情况.仿真试验表明不管SIMO信道是否包含公零点,也不管零点是否在单位圆内,本文算法都表现出超越于子空间法和线性预报法的优良性能. | 张志涌 BAI Erwei | 2005 | 电子学报2005，33，4： | 23 |

| 10 | Correlativity between blood measures related to blood stasis blocking collaterals and gene expression of angiotensin-converting enzyme of renal cortex in diabetic rats and effect of stasis removing and collaterals dredging显示文摘OBJECTIVE: To investigate the correlativity between the changes of blood measures related to blood stasis blocking collaterals and gene expression levels of angiotensin-converting enzyme(ACE)and ACE2 ofrenal cortex in diabetic rats with stasis blocking collaterals syndrome, as well as the effectof stasis removing and collaterals dredging.METHODS: Male Sprague-Dawley rats were divided randomly into normal control group(C group),high-carbohydrate-fat control group(H group) and streptozotocin(STZ)-injecting group. The diabeticrats were induced from rats in the STZ-injecting groupby high-carbohydrate-fat diet combined with STZ intraperitoneal injection, with sustained high-carbohydrate-fat diet fed afterwards, and were further divided into model group(M group)and Chinese medicine of stasis removing and collaterals dredging group(Z group). Rats in the Z group were fed with stasis-removing-and-collaterals-dredging herbal granule suspension intragastrically daily for 16 weeks, while drinking water of corresponding volume was administrated to the rats in other groups. At the end of the 16 th week after successful establishment of models, the ultrastructures of glomeruli in different groups were detected by a transmission electron microscopy; and blood measures related to blood stasis blocking collaterals, including lipid profile and blood viscosity measures, were tested, as well as the relative gene expressions of ACE and ACE2.RESULTS: Changes in ultrastructures of glomeruli in the M group were characterized by lack of clarity in structure and occasional thickening of glomerular basement membrane and extensive fusion in foot processes. The correlation analysis showed that there were positive correlations between lipid profile, blood viscosity, and the ACE mRNA expression levels in the M group(P<0.05), except for cholesterol. And except for triglyceride, the blood measures were in negative correlation with the ACE2 mRNA expression levels in the M group(P<0.05).Compared with the C and H groups, the lipid profile, plasma viscosity and blood viscosity were significantly higher(P<0.01). All the above-mentioned measures were significantly improved in the Z group rats(P<0.05). ACE mRNA expression was significantly higher in the M group thanin the C group(P<0.05). ACE2 mRNA level was significantly lower in the M group than in the C and H groups(P<0.01)and its levelin the Z group was higher than that in the M group(P<0.01).CONCLUSION: Blood measuresrelated to blood stasis blocking collaterals had positive linear correlations with ACE mRNAexpression and negative linear correlations with ACE2 mRNA expression in the M group. Chinese recipe of stasis removing and collaterals dredging could play a renal protecting role for diabetic rats by reducing lipid profile and blood viscosity, down-regulating ACE mRNA expression and up-regulating ACE2 mRNA expression. | Jing Xu Lu Bai Erwei Ma Qian Guo Yuehua Wang Muqing Zhang Zhiqiang Chen | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 1 |

| 19 | Glucuronic acid metabolites of phenolic acids target AKT-PH domain to improve glucose metabolism显示文摘Objective:Phenolic acids widely exist in the human diet and exert beneficial effects such as improving glucose metabolism.It is not clear whether phenolic acids or their metabolites play a major role in vivo.In this study,caffeic acid(CA)and ferulic acid(FA),the two most ingested phenolic acids,and their glucuronic acid metabolites,caffeic-4’-O-glucuronide(CA4G)and ferulic-4’-O-glucuronide(FA4G),were investigated.Methods:Three insulin resistance models in vitro were established by using TNF-a,insulin and palmitic acid(PA)in HepG2 cells,respectively.We compared the effects of FA,FA4G,CA and CA4G on glucose metabolism in these models by measuring the glucose consumption levels.The potential targets and related pathways were predicted by network pharmacology.Fluorescence quenching measurement was used to analyze the binding between the compounds and the predicted target.To investigate the binding mode,molecular docking was performed.Then,we performed membrane recruitment assays of the AKT pleckstrin homology(PH)domain with the help of the PH-GFP plasmid.AKT enzymatic activity was determined to compare the effects between the metabolites with their parent compounds.Finally,the downstream signaling pathway of AKT was investigated by Western blot analysis.Results:The results showed that CA4G and FA4G were more potent than their parent compounds in increasing glucose consumption.AKT was predicted to be the key target of CA4G and FA4G by network pharmacology analysis.The fluorescence quenching test confirmed the more potent binding to AKT of the two metabolites compared to their parent compounds.The molecular docking results indicated that the carbonyl group in the glucuronic acid structure of CA4G and FA4G might bind to the PH domain of AKT at the key Arg-25 site.CA4G and FA4G inhibited the translocation of the AKT PH domain to the membrane,while increasing the activity of AKT.Western blot analysis demonstrated that the metabolites could increase the phosphorylation of AKT and downstream glycogen synthase kinase 3βin the AKT signaling pathway to increase glucose consumption.Conclusion:In conclusion,our results suggested that the metabolites of phenolic acids,which contain glucuronic acid,are the key active substances and that they activate AKT by targeting the PH domain,thus improving glucose metabolism. | Jie Gao Manqian Zhang Xingwang Zu Xue Gu Erwei Hao Xiaotao Hou Gang Bai | 2023 | Chinese Herbal Medicines2023，15，3： | 0 |
| 20 | Outliers, inliers and the generalized least trinuned squares estimator in system identification显示文摘The least trimmed squares estimator (LTS) is a well known robust estimator in terms of protecting the estimate fiom the outliers. Its high computational complexity is however a problem in practice. We show that the LTS estimate can be obtained by a simple algorithm with the complexity O( NIn N) for hrge N, where N is the number of measurements. We also show that though the LTS is robust in terms of the outliers, it is sensitive to the inliers. The concept of the inliers is introduced. Moreover, the Generalized Least Trimmed Squares estimator (GLTS) together with its solution are presented that reduces the effect of both the outliers and the inliers. | Erwei BAI | 2003 | 控制理论与应用(英文版)2003，1，1： | 0 |
