| 1 | Spatial and temporal distribution of Neolithic sites in coastal China:Sea level changes, geomorphic evolution and human adaption显示文摘The East China coastal plain is one of the most important Neolithic culture areas in China, where rich archaeological sites including those producing the earliest domesticated rice are observed. It is also a place where landscape has experienced dramatic evolution during the Holocene when both sea level and climate changed, such that it is an ideal place for studying human-environment interaction. This study investigated over 2000 sites of pre-history and Shang and Zhou Dynasties, with 655 of which being Neolithic ages, by using DEM and GIS methods. The results suggest that the spatial and temporal distribution of Neolithic sites has largely been controlled by landscape evolution(particularly changes in coastal line), which ultimately governed by sea level changes. During early Holocene, Neolithic sites sparsely distributed in the intermountain basins of east Zhejiang Province, far from the influence of ocean. Over the period of 9–7 ka, the coastal plain(including the shelf) was largely submerged,only the feet of low hills to the south and southwest of the study area, and islands protruding the estuary, cradled limited number of settlements with characteristic 'maritime components'. At about 7 ka, sea level rise decelerated prominently, while sediments supply in the drainage remained high value, the combination of which led to land formation and propagation. Vast space during this period facilitated the growth of settlements in both size and number. In the mean time, however, the coastal plain was vulnerable to extreme environmental events such as storms and flooding owning to its geomorphic nature, which exerted great influence on the rise and fall of Neolithic culture. | ZHENG HongBo ZHOU YouSheng YANG Qing HU ZhuJun LING GuangJiu ZHANG JuZhong GU ChunGuang WANG YingYing CAO YeTing HUANG XianRong CHENG Yue ZHANG XiaoYu WU WenXiang | 2018 | Science China Earth Sciences2018，61，2： | 7 |

Human brain tissue, unlike animal tissues, is an irreplaceable resource for the study of neurological diseases (1)Aimed at scientific research and education, the roles of human brain tissue repositories are to acquire brain tissue from donors, prepare, process, and preserve collected samples,provide tissue to specific eligible facilities, and determine the characteristics of each tissue sample. | Wenying Qiu Hanlin Zhang Aimin Bao Keqing Zhu Yue Huang Xiaoxin Yan Jing Zhang Chunjiu Zhong Yong Shen Jiangning Zhou Xiaoying Zheng Liwei Zhang Yousheng Shu Beisha Tang Zhenxin Zhang Gang Wang Ren Zhou Bing Sun Changlin Gong Shumin Duan Chao Ma | 2019 | Neuroscience Bulletin2019，35，2： | 6 |
| 3 | Serum levels of perfluorinated compounds in the general population in Shenzhen, China显示文摘Perfluorinated compounds (PFCs) have been detected in many environmental matrices, biota, and nonoccupationally exposed populations in China recently. However, little is known about the distribution and levels of various PFCs in the general population living in areas where there is PFC exposure. In the present study, the levels and prevalence of ten target PFCs were determined in 227 serum samples from a population of nonoccupationally exposed individuals in Shenzhen, China. Results indicated that human exposure to PFCs was prevalent in Shenzhen. Perfluorooctanoate (PFOA) was the dominant PFC contaminant in the serum samples, with a median concentration of 6.72 ng/mL, followed by perfluorooctane sulfonate (PFOS) with a median concentration of 2.07 ng/mL. Other PFCs were detected at much lower concentrations, with median concentrations ranging from 0.02 to 0.87 ng/mL. Statistically, no significant (P>0.05) gender differences were observed for any of the PFCs. Significant (P<0.01) positive correlations were found between age and serum concentrations of the target PFCs, except for perfluorobutane sulfonate (R = 0.16, P = 0.01), perfluorohexanoic acid (R = 0.08, P = 0.22), and perfluoroheptanoic acid (R = 0.11, P = 0.10). Based on the one-compartment pharmacokinetic model, the total daily intakes of PFOA and PFOS for the general population in Shenzhen were calculated as 0.63 and 0.20 ng/kg body weight/day, respectively. | LI Xiao ZHANG JianQing LIU Wei LI XiaoNa ZHANG Xin JIANG YouSheng ZHOU Jian JIN YiHe | 2011 | Chinese Science Bulletin2011，56，28： | 5 |
| 4 | Peripheral Lymphocyte Subsets as a Marker of Parkinson's Disease in a Chinese Population显示文摘In this study, we conducted a clinical analysis of lymphocyte subtypes in 268 patients with Parkinson's disease(PD) to assess their clinical impact as a potential marker of advanced PD in Chinese patients. The participants comprised 268 sporadic PD patients and 268 healthy controls. The numbers of natural killer(NK) cells and CD3+, CD3+CD4+, CD3+CD8+, and CD19+ lymphocytes from peripheral blood were determined by immunostaining and flow cytometric analysis and the percentages of these CD+ T cells were calculated. The ratio of regulatory T(Treg)/helper T 17(Th17) lymphocytes from 64 PD patients and 46 controls was determined by flow cytometric analysis.The results showed that the percentage of NK cells was higher in advanced PD patients than in controls(22.92% ±10.08% versus 19.76% ± 10.09%, P = 0.006), while CD3+ T cells are decreased(62.93% ± 9.27% versus65.75% ± 9.13%, P = 0.005). The percentage of CD19+B cells in male patients was lower(P = 0.021) than in female patients, whereas NK cells were increased(P \ 0.0001). The scores on the Unified Parkinson's Disease Rating Scale(UPDRS) and the Non-Motor Symptoms Scale in late-onset PD patients were significantly higher than those in earlyonset patients(P = 0.024 and P = 0.007, respectively). The percentage of CD19+ B cells in patients with UPDRS scores[24 was lower than in those with scores \24(10.17% ±4.19% versus 12.22% ± 5.39%, P = 0.009). In addition, the Treg/Th17 ratio in female patients was higher than that in female controls(13.88 ± 6.32 versus 9.94 ± 4.06, P =0.042). These results suggest that the percentages of NK cells,CD3+ T cells, and CD19+ B cells along with the Treg/Th17 ratio in peripheral blood may be used to predict the risk of PD in Chinese individuals and provide fresh avenues for novel diagnostic biomarkers and therapeutic designs. | Luan Cen Chaohao Yang Shuxuan Huang Miaomiao Zhou Xiaolu Tang Kaiping Li Wenyuan Guo Zhuohua Wu Mingshu Mo Yousheng Xiao Xiang Chen Xinling Yang Qinhui Huang Chaojun Chen Shaogang Qu Pingyi Xu | 2017 | Neuroscience Bulletin2017，33，5： | 5 |
| 5 | Increased mtDNA copy number promotes cancer progression by enhancing mitochondrial oxidative phosphorylation in microsatellite-stable colorectal cancer显示文摘Colorectal cancer is one of the leading causes of cancer death worldwide.According to global genomic status,colorectal cancer can be classified into two main types:microsatellite-stable and microsatellite-instable tumors.Moreover,the two subtypes also exhibit different responses to chemotherapeutic agents through distinctive molecular mechanisms.Recently,mitochondrial DNA depletion has been shown to induce apoptotic resistance in microsatellite-instable colorectal cancer.However,the effects of altered mitochondrial DNA copy number on the progression of microsatellite-stable colorectal cancer,which accounts for the majority of colorectal cancer,remain unclear.In this study,we systematically investigated the functional role of altered mitochondrial DNA copy number in the survival and metastasis of microsatellite-stable colorectal cancer cells.Moreover,the underlying molecular mechanisms were also explored.Our results demonstrated that increased mitochondrial DNA copy number by forced mitochondrial transcription factor A expression significantly facilitated cell proliferation and inhibited apoptosis of microsatellitestable colorectal cancer cells both in vitro and in vivo.Moreover,we demonstrated that increased mitochondrial DNA copy number enhanced the metastasis of microsatellite-stable colorectal cancer cells.Mechanistically,the survival advantage conferred by increased mitochondrial DNA copy number was caused in large part by elevated mitochondrial oxidative phosphorylation.Furthermore,treatment with oligomycin significantly suppressed the survival and metastasis of microsatellite-stable colorectal cancer cells with increased mitochondrial DNA copy number.Our study provides evidence supporting a possible tumor-promoting role for mitochondrial DNA and uncovers the underlying mechanism,which suggests a potential novel therapeutic target for microsatellite-stable colorectal cancer. | Xiacheng Sun Lei Zhan Yibing Chen Gang Wang Linjie He Qian Wang Feng Zhou Fang Yang Jin Wu Yousheng Wu Jinliang Xing Xianli He Qichao Huang | 2018 | Signal Transduction and Targeted Therapy2018，3，1： | 3 |
| 6 | Enhancement of oral bioavailability and anti-Parkinsonian efficacy of resveratrol through a nanocrystal formulation显示文摘Resveratrol(RES),a non-flavonoid polyphenol extracted from a wide variety of plants,exhibits neuroprotective activities against Parkinson’s disease(PD).However,undesirable water solubility of RES reduces its oral bioavailability and demonstrates lowefficacy in blood and brain,thus limiting its application.In present study,a nanocrystal formulation of RES(RES-NCs)was developed to enhance its oral bioavailability and delivery into brain for PD treatment.RES-NCs were fabricated with hydroxypropyl methylcellulose(HPMC)stabilizer via antisolvent precipitation approach.The obtained RES-NCs displayed the particle size of 222.54±1.66 nm,the PDI of 0.125±0.035,the zeta potential of−9.41±0.37mV,and a rapid in vitro dissolution rate.Molecular dynamics simulation of RES and HPMC revealed an interaction energy of−68.09 kJ/mol and a binding energy of−30.98±0.388 kJ/mol,indicating that the spontaneous binding between the two molecules is through van der Waals forces.RES-NCs conferred enhanced cellular uptake as well as improved permeability relative to pure RES.In addition,RES-NCs were able to protect neurons against cytotoxicity induced by MPP+.Meanwhile,RES-NCs exerted no significant toxic effects on zebrafish embryos and larvae,and did not influence their survival and hatching rates.When orally administered to rats,RES-NCs exhibited more favorable pharmacokinetics than pure RES,with higher plasma and brain concentrations.More importantly,MPTP-induced PD mice showed notable improvements in behavior,attenuated dopamine deficiency,and elevated levels of dopamine and its metabolites after the treatment with RES-NCs.Furthermore,immunoblot analysis revealed that the neuroprotective role of RES-NCsmay be at least partially mediated by Akt/Gsk3βsignaling pathway.Taken altogether,RES-NCs can serve as a potential treatment modality for PD,offering means of improving RES oral bioavailability and brain accumulation. | Sha Xiong Wei Liu Yile Zhou Yousheng Mo Yao Liu Xiaojia Chen Huafeng Pan Dongsheng Yuan QiWang Tongkai Chen | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，4： | 3 |

| 14 | An Anonymous Authentication Scheme with Controllable Linkability for Vehicle Sensor Networks显示文摘Vehicle sensor networks(VSN)play an increasingly important part in smart city,due to the interconnectivity of the infrastructure.However similar to other wireless communications,vehicle sensor networks are susceptible to a broad range of attacks.In addition to ensuring security for both data-at-rest and data-in-transit,it is essential to preserve the privacy of data and users in vehicle sensor networks.Many existing authentication schemes for vehicle sensor networks are generally not designed to also preserve the privacy between the user and service provider(e.g.,mining user data to provide personalized services without infringing on user privacy).Controllable linkability can be used to facilitate an involved entity with the right linking key to determine whether two messages were generated by the same sender,while preserving the anonymity of the signer.Such a functionality is very useful to provide personalized services.Thus,in this paper,a threshold authentication scheme with anonymity and controllable linkability for vehicle sensor networks is constructed,and its security is analyzed under the random oracle model. | Yousheng Zhou Lvjun Chen Xiaofeng Zhao Zheng Yang | 2020 | Computer Modeling in Engineering & Sciences2020，，12： | 0 |
| 15 | Whistle signal variations among three Indo-Pacific humpback dolphin populations in the South China Sea:a combined effect of the Qiongzhou Strait’s geographical barrier function and local ambient noise?显示文摘Geographic variations in the dolphin whistles could be useful in assessing association and isolation among populations.Whistle of free-ranging Indo-Pacific humpback dolphins(Sousa chinensis)among the Pearl River Estuary(PRE),Leizhou Bei(LZB)and Sanniang Bay(SNB)populations were investigated.A total of 2850 whistles with legible fundamental contour were extracted and 15 acoustic parameters were measured.Contrary to SNB,PRE and LZB had the same relative proportion of tonal type compositions with flat and sine representing the most frequent types.The generalized linear model analysis showed significant acoustic difference among populations and tonal types.All frequency parameters in SNB were significantly higher than those in PRE and LZB,where no significant variation was observed in most of the parameters either at the population level or within each tonal type.Canonical discriminant functions analysis showed a smaller difference between PRE and LZB than between PRE and SNB and between LZB and SNB.Compared with previous recordings,recent recordings demonstrated a consistent pattern of becoming higher in whistle frequency parameters in both LZB and SNB populations,suggesting that noise pollution in LZB and SNB increasing with time according to the acoustic niche hypothesis.Dolphin whistle’s geographic variations could be shaped by the combined function of the geographical barrier function of the Qiongzhou strait and local ambient noise.Considering the isolated condition and the relatively smaller population size of the humpback dolphin in the SNB,more effective and proactive conservation actions should be taken to prevent the extinction of small populations. | Jing YUAN Zhitao WANG Pengxiang DUAN Yousheng XIAO Hongke ZHANG Zhixiong HUANG Ruichun ZHOU Hua WEN Kexiong WANG Ding WANG | 2021 | Integrative Zoology2021，16，4： | 0 |
| 16 | CHCHD2 maintains mitochondrial contact site and cristae organizing system stability and protects against mitochondrial dysfunction in an experimental model of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is the second most common neurodegenerative disease after Alzheimer’s dementia.Mitochondrial dysfunction is involved in the pathology of PD.Coiled-coil-helix-coiled-coil-helix domain-containing 2(CHCHD2)was identified as associated with autosomal dominant PD.However,the mechanism of CHCHD2 in PD remains unclear.Methods:Short hairpin RNA(ShRNA)-mediated CHCHD2 knockdown or lentivirus-mediated CHCHD2 overexpression was performed to investigate the impact of CHCHD2 on mitochondrial morphology and function in neuronal tumor cell lines represented with human neuroblastoma(SHSY5Y)and HeLa cells.Blue-native polyacrylamide gel electrophoresis(PAGE)and two-dimensional sodium dodecyl sulfate-PAGE analysis were used to illustrate the role of CHCHD2 in mitochondrial contact site and cristae organizing system(MICOS).Co-immunoprecipitation and immunoblotting were used to address the interaction between CHCHD2 and Mic10.Serotype injection of adeno-associated vector-mediated CHCHD2 and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)administration were used to examine the influence of CHCHD2 in vivo.Results:We found that the overexpression of CHCHD2 can protect against methyl-4-phenylpyridinium(MPP+)-induced mitochondrial dysfunction and inhibit the loss of dopaminergic neurons in the MPTP-induced mouse model.Furthermore,we identified that CHCHD2 interacted with Mic10,and overexpression of CHCHD2 can protect against MPP+-induced MICOS impairment,while knockdown of CHCHD2 impaired the stability of MICOS.Conclusion:This study indicated that CHCHD2 could interact with Mic10 and maintain the stability of the MICOS complex,which contributes to protecting mitochondrial function in PD. | Lin Lu Hengxu Mao Miaomiao Zhou Yuwan Lin Wei Dai Jiewen Qiu Yousheng Xiao Mingshu Mo Xiaoqin Zhu Zhuohua Wu Zhong Pei Wenyuan Guo Pingyi Xu Xiang Chen | 2022 | Chinese Medical Journal2022，，13： | 0 |
| 17 | Dynamic multi-keyword fuzzy ranked search with leakage resilience over encrypted cloud data显示文摘To achieve the confidentiality and retrievability of outsourced data simultaneously,a dynamic multi-keyword fuzzy ranked search scheme(DMFRS)with leakage resilience over encrypted cloud data based on two-level index structure was proposed.The first level index adopts inverted index and orthogonal list,combined with 2-gram and location-sensitive Hashing(LSH)to realize a fuzzy match.The second level index achieves user search permission decision and search result ranking by combining coordinate matching with term frequency-inverse document frequency(TF-IDF).A verification token is generated within the results to verify the search results,which prevents the potential malicious tampering by cloud service providers(CSP).The semantic security of DMFRS is proved by the defined leakage function,and the performance is evaluated based on simulation experiments.The analysis results demonstrate that DMFRS gains certain advantages in security and performance against similar schemes,and it meets the needs of storage and privacy-preserving for outsourcing sensitive data. | Zhou Yousheng Huang Miao Liu Yuanni Chen Zigang | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，2： | 0 |
| 18 | A time-aware searchable encryption scheme for EHRs显示文摘Despite the benefits of EHRs (Electronic Health Records), there is a growing concern over the risks of privacy exposure associated with the technologies of EHR storing and transmission. To deal with this problem, a timeaware searchable encryption with designated server is proposed in this paper. It is based on Boneh's public key encryption with keyword search and Rivest's timed-release cryptology. Our construction has three features: the user cannot issue a keyword search query successfully unless the search falls into the specific time range;only the authorized user can generate a valid trapdoor;only the designated server can execute the search. Applying our scheme in a multi-user environment, the number of the keyword ciphertexts would not increase linearly with the number of the authorized users. The security and performance analysis shows that our proposed scheme is securer and more efficient than the existing similar schemes. | Yousheng Zhou Xiaofeng Zhao Siling Liu Xingwang Long Wenjun Luo | 2019 | Digital Communications and Networks2019，5，3： | 0 |
