| 1 | μ-and m-calpain expression and activity changes following diethylstilbestrol injection in the rat anterior pituitary显示文摘Little is known about changes in calpain activity in the pituitary gland.In the present study,μ-and m-calpain activity changes were detected in the rat anterior pituitary following intraperitoneal injection of diethylstilbestrol.Double-immunofluorescence labeling confirmed colocalization of μ-and m-calpain in prolactin-secreting cells(lactotrophs).Western blot analysis revealed significantly increased expression of both calpains,which accompanied upregulated cytosol and membrane zymographic activities at 12 weeks following diethylstilbestrol injection,compared with rats injected with sunflower oil.Moreover,following estrogen injection,pituitary gland pathological damage gradually worsened with increasing time.Results demonstrated that estrogen regulated calpain expression and activity,and both calpains participated in the pathophysiological processes of the pituitary gland.Ubiquitous calpain expression could serve as an effective target for anti-estrogen drugs. | Weijiang Zhao Zhongfang Shi Fang Yuan Guilin Li Yazhuo Zhang Zhongcheng Wang | 2011 | Neural Regeneration Research2011,6,1: | 7 |

| 3 | Anti-biofilm and remineralization effects of chitosan hydrogel containing amelogeninderived peptide on initial caries lesions显示文摘In this study,we have designed a more clinically powerful anti-caries treatment by applying the amelogenin-derived peptide QP5 to the antibacterial carrier material chitosan in a hydrogel(CS-QP5 hydrogel),and characterized its effects on the inhibition of a cariogenic biofilm and the promotion of the remineralization of the initial caries lesions.The results indicated that the CS-QP5 hydrogel sustainably inhibited the growth of the Streptococcus mutans biofilm,lactic acid production and the metabolic activity over a prolonged period of time.Moreover,the CS-QP5 hydrogel promoted the remineralization of early enamel lesions,which were indicated by surface microhardness(,polarized light microscopy and transverse microradiography.In conclusion,the CS-QP5 hydrogel shows good potential for caries control in the clinic because of its antibacterial effects as well as the remineralization of initial enamel carious lesions even in a biofilm model over a prolonged period of time. | Qian Ren Zhongcheng Li Longjiang Ding Xiuqing Wang Yumei Niu Xi Qin Xuedong Zhou Linglin Zhang | 2018 | Regenerative Biomaterials2018,5,2: | 5 |

| 5 | Prediction Model of Coal Reservoir Pressure and its Implication for the Law of Coal Reservoir Depressurization显示文摘The main methods of coalbed methane(CBM)development are drainage and depressurization,and a precise prediction of coal reservoir pressure is thus crucial for the evaluation of reservoir potentials and the formulation of reasonable development plans.This work established a new reservoir pressure prediction model based on the material balance equation(MBE)of coal reservoir,which considers the self-regulating effects of coal reservoirs and the dynamic change of equivalent drainage area(EDA).According to the proposed model,the reservoir pressure can be predicted based on reservoir condition data and the actual production data of a single well.Compared with traditional reservoir pressure prediction models which regard EDA as a fixed value,the proposed model can better predict the average pressure of reservoirs.Moreover,orthogonal experiments were designed to evaluate the sensitivity of reservoir parameters on the reservoir pressure prediction results of this proposed model.The results show that the saturation of irreducible water is the most sensitive parameter,followed by Langmuir volume and reservoir porosity,and Langmuir pressure is the least sensitive parameter.In addition,the pressure drop of reservoirs is negatively correlated with the saturation of irreducible water and the Langmuir volume,while it is positively correlated with porosity.This work analyzed the reservoir pressure drop characteristics of the CBM wells in the Shizhuangnan Block of the Qinshui Basin,and the results show that the CBM reservoir depressurization can be divided into three types,i.e.,rapidly drop type,medium-term stability type,and slowly drop type.The drainage features of wells were reasonably interpreted based on the comprehensive analysis of the reservoir depressurization type;the latter was coupled to the corresponding permeability dynamic change characteristics,eventually proving the applicability of the proposed model. | YAN Xinlu ZHANG Songhang TANG Shuheng LI Zhongcheng WANG Kaifeng YI Yongxiang DANG Feng HU Qiuping | 2019 | Acta Geologica Sinica(English Edition)2019,93,3: | 2 |

| 7 | Privacy Protection for Blockchains with Account and Multi-Asset Model显示文摘The blockchain technology has been applied to wide areas.However,the open and transparent properties of the blockchains pose serious challenges to users’privacy.Among all the schemes for the privacy protection,the zero-knowledge proof algorithm conceals most of the private information in a transaction,while participants of the blockchain can validate this transaction without the private information.However,current schemes are only aimed at blockchains with the UTXO model,and only one type of assets circulates on these blockchains.Based on the zero-knowledge proof algorithm,this paper proposes a privacy protection scheme for blockchains that use the account and multi-asset model.We design the transaction structure,anonymous addresses and anonymous asset metadata,and also propose the methods of the asset transfer and double-spending detection.The zk-SNARKs algorithm is used to generate and to verify the zero-knowledge proof.And finally,we conduct the experiments to evaluate our scheme. | Donghui Ding Kang Li Linpeng Jia Zhongcheng Li Jun Li Yi Sun | 2019 | China Communications2019,16,6: | 2 |

| 11 | IC Testing by Phase Classification Based on Behavioral Description of RTL显示文摘The growing complexity of integrated circuits (ICs) is driving the trend of IC testing towards testing based on behavioral descriptions of register-transfer level (RTL). A behavioral description contains an algorithmic specification of functionality of design. It may contain little or even no information about the design’s cycle-by-cycle behavior or structural implementation. However, it usually has an interior variable to lead the process of its functional phases. This interior variable is named phase variable. The functional behavior of a digital circuit changes according to different values of a phase variable. By analyzing some ITC99 benchmark circuits, this paper presents a way to generate tests for a circuit by tracing the value change of a phase variable in the circuit. | Huawei Li Yinghua Min Zhongcheng Li | 2000 | 湖南大学学报(自然科学版)2000,27,S2: | 1 |

| 13 | Adaptive cubature Kalman filter with the estimation of correlation between multiplicative noise and additive measurement noise显示文摘Mobile robots are often subject to multiplicative noise in the target tracking tasks,where the multiplicative measurement noise is correlated with additive measurement noise.In this paper,first,a correlation multiplicative measurement noise model is established.It is able to more accurately represent the measurement error caused by the distance sensor dependence state.Then,the estimated performance mismatch problem of Cubature Kalman Filter(CKF)under multiplicative noise is analyzed.An improved Gaussian filter algorithm is introduced to help obtain the CKF algorithm with correlated multiplicative noise.In practice,the model parameters are unknown or inaccurate,especially the correlation of noise is difficult to obtain,which can lead to a decrease in filtering accuracy or even divergence.To address this,an adaptive CKF algorithm is further provided to achieve reliable state estimation for the unknown noise correlation coefficient and thus the application of the CKF algorithm is extended.Finally,the estimated performance is analyzed theoretically,and the simulation study is conducted to validate the effectiveness of the proposed algorithm. | Quanbo GE Zhongcheng MA Jinglan LI Qinmin YANG Zhenyu LU Hong LI | 2022 | Chinese Journal of Aeronautics2022,35,5: | 1 |

| 17 | First-principles study of He point-defects in HCP rare-earth metals显示文摘He defect properties in Sc, Y, Gd, Tb, Dy, Ho, Er and Lu were studied using first-principles calculations based on density functional theory. The results indicate that the formation energy of an interstitial He atom is smaller than that of a substitutional He atom in all hcp rare-earth metals considered. Furthermore, the tetrahedral interstitial position is more favorable than an octahedral position for He defects. The results are compared with those from bcc and fcc metals. | YANG LI CHEN RuCheng PENG ShuMing LONG XingGui WU ZhongCheng GAO Fei ZU XiaoTao | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,5: | 1 |
