1Secondary organic carbon quantification and source apportionment of PM_(10) in Kaifeng, China显示文摘During 2005, the filter samples of ambient PM10 from five sites and the source samples of particulate matter were collected in Kaifeng, Henan Province of China. Nineteen elements, water-soluble ions, total carbon (TC) and organic carbon (OC) contained in samples were analyzed. Seven contributive source types were identified and their contributions to ambient PM10 were estimated by chemical mass balance (CMB) receptor model. Weak associations between the concentrations of organic carbon and element carbon (EC) were observed during the sampling periods, indicating that there was secondary organic aerosol pollution in the urban atmosphere. An indirect method of 'OC/EC minimum ratio' was applied to estimate the concentration of secondary organic carbon (SOC). The results showed that SOC contributed 26.2%, 32.4% and 18.0% of TC in spring, summer-fall and winter, respectively, and the annual average SOC concentration was 7.07 μg/m3, accounting for 5.73% of the total mass in ambient PM10. The carbon species concentrations in ambient PM10 were recalculated by subtracting SOC concentrations from measured concentrations of TC and OC to increase the compatibility of source and receptor measurements for CMB model.WU Lin FENG Yinchang WU Jianhui ZHU Tan BI Xiaohui HAN Bo YANG Weihong YANG Zhiqiang 2009Journal of Environmental Sciences2009,21,10:26
2Attack Simulation Model and Channel Statistics in Underwater Acoustic Sensor Networks显示文摘In recent years,underwater acoustic wireless sensor networks have been used in many areas.There have been many field trials of acoustic propagation models and statistics for shallow water conditions.However,field trials are limited environmentally and,hence,not widely accepted.Simulations of the impulse response of a shallow underwater acoustic channel allows less expensive system tests that are reproducable.This paper presents a shallow water acoustic channel model based on the actual acoustic propagation characteristics with path attenuation,ambient noise,multiple paths,and Doppler effects.The second-order statistical characteristics of the simulation model are verified with the autocorrelations and crosscorrelations of the quadrature components and the complex envelopes of channel impulse responses.The channel model is implemented in Matlab with the results showing that the absorption coefficient and path losses are both dependent on the frequencies and propagation distances and that the path gain can be improved with Light of Sight (LOS) and short range acoustic propagation.Analysis of the channel impulse response and the frequency response that the zero-order Bessel function of first kind can be used to describe the correlation functions for the impulse response.The shallow underwater acoustic channel is time-varying and can not be modeled as a wide-sense stationary-uncorrelated scattering channel.Nan Jing Weihong Bi Qing Yue 2011Tsinghua Science and Technology2011,16,6:2
3Generating Giant Membrane Vesicles from Live Cells with Preserved Cellular Properties显示文摘Biomimetic giant membrane vesicles,with size and lipid compositions comparable to cells,have been recognized as an attractive experimental alternative to living systems.Due to the similarity of their membrane structure to that of body cells,cell-derived giant plasma membrane vesicles have been used as a membrane model for studying lipid/protein behavior of plasma membranes.However,further application of biomimetic giant membrane vesicles has been hampered by the side-efects of chemical vesiculants and the utilization of osmotic bufer.We herein develop a facile strategy to derive giant membrane vesicles(GMVs)from mammalian cells in biofriendly medium with high yields.Tese GMVs preserve membrane properties and adaptability for surface modifcation and encapsulation of exogenous molecules,which would facilitate their potential biological applications.Moreover,by loading GMVs with therapeutic drugs,GMVs could be employed for drug transport to tumor cells,which represents another step forward in the biomedical application of giant membrane vesicles.Tis study highlights biocompatible GMVs with biomimicking membrane surface properties and adaptability as an ideal platform for drug delivery strategies with potential clinical applications.Qiaoling Liu Cheng Bi Jiangling Li Xuejiao Liu Ruizi Peng Cheng Jin Yang Sun Yifan Lyu Hui Liu Huijing Wang Can Luo Weihong Tan 2019Research2019,,1:2
4Multiple Center Research on Relationship Between Screening Quality and Detection of Cervical Cancer—Six Provinces,China,June–December 2021显示文摘The coverage and quality of screening are essential for reducing the incidence of cervical precancers and cervical cancer.This multicenter study aimed to investigate the relationship between screening quality and the detection of cervical precancers and cervical cancer.The study was conducted from June to December 2021 in six hospitals across six provinces.The 2,945 participants were non-pregnant women who underwent colposcopy examinations.The average age of participants was 40.9±11.5 years old.Only 6.9%of participants had received human papillomavirus(HPV)vaccination.A total of 92.6%of participants had abnormal cervical screening results.Of the participants,577 had high-grade squamous intraepithelial lesions(HSIL)or worse(≥HSIL),with a detection rate of 19.6%.Univariate analysis indicated that a lack of cervical cancer screening history in the past five years,as well as positive cervical screening and abnormal colposcopic impression,were independent associated factors of the≥HSIL detection rate.A multivariable logistic regression showed that positive cervical screening[odds ratio(OR)=1.75,95%confidence interval(CI):1.07–2.86]was a risk factor for detecting≥HSIL.Low-grade,high-grade,and cancer of colposcopic impression were associated with a higher risk for detecting≥HSIL(OR=2.94,95%CI:2.13–4.08;OR=36.64,95%CI:26.07–51.48).It is important to disseminate health knowledge to improve public awareness of cervical cancer prevention and to enhance the capacity building of professional staff to improve the quality of cervical cancer screening.Xiaosong Zhang Weihong Chen Xinxin Zhu Hui Bi Qingping Zhao Yunfeng Fu Lina Zhang Chunmei Zhang Ning Huang 2023China CDC weekly2023,5,14:1

8Design and research of magnetic field sensor based on grapefruit optical fiber filled with magnetic fluid显示文摘A novel magnetic field sensor was proposed based on the grapefruit optical fiber with the magnetic fluid injected into the six air holes.The sensor utilizes the Mach-Zehnder interference(MZI).The light is transmitted through the single-mode fiber to the fusion splice point and is divided into two parts.When the light passes through the cladding air hole with magnetic fluid,it interferes with the core light,and the change of the interference light is related with the change of the magnetic field.The sensor cavity length is 6 cm.It can be obtained from the experimental results that the magnetic field sensitivity reaches up to 2.243 nm/Oe with the range from 0 to 2.28 Oe.The sensor has the advantages of easy fabrication,easy installation and low cost.The findings provide new ideas for the study of ocean wind electromagnetic fields.WANG Mengye JIN Wa LIU Xuejing SUN Wenjie ZHANG Chenhui BI Weihong 2022Optoelectronics Letters2022,18,5:1
9Prevalence of High-Risk Human Papillomavirus in Cervical Intraepithelial Neoplasia in the Pre-Vaccine Era—China,2017–2018显示文摘What is already known about this topic?Human papillomavirus(HPV)type-specific strategies play a key role in the prevention of cervical intraepithelial neoplasia(CIN),but evidence on the HPV type-specific prevalence in CIN is limited.What is added by this report?This multicentric study estimates the prevalence of high-risk HPV types in CIN cases and the associations of HPV infection patterns with high-grade CIN in China in 2017–2018.What are the implications for public health practice?Population-based prevention strategies should give preference to HPV-16 and 18,and strategies for non-16/18 high-risk HPV are essential for the elimination of cervical cancer.Heling Bao Weihong Chen Xiaosong Zhang Hui Bi Yun Zhao Liwen Fang Shu Cong Feng Tan Linhong Wang 2022China CDC weekly2022,4,48:1

14Recommendations for the diagnosis and treatment of paroxysmal kinesigemc dyskinesia: an expert consensus in China显示文摘Paroxysmal dyskinesias are a group of neurological diseases characterized by intermittent episodes of involuntary movements with different causes.Paroxysmal kinesigenic dyskinesia(PKD)is the most common type of paroxysmal dyskinesia and can be divided into primary and secondary types based on the etiology.Clinically,PKD is characterized by recurrent and transient attacks of involuntary movements precipitated by a sudden voluntary action.The major cause of primary PKD is genetic abnormalities,and the inheritance pattern of PKD is mainly autosomal-dominant with incomplete penetrance.The proline-rich transmembrane protein 2(PRRT2)was the first identified causative gene of PKD,accounting for the majority of PKD cases worldwide.An increasing number of studies has revealed the clinical and genetic characteristics,as well as the underlying mechanisms of PKD.By seeking the views of domestic experts,we propose an expert consensus regarding the diagnosis and treatment of PKD to help establish standardized clinical evaluation and therapies for PKD.In this consensus,we review the clinical manifestations,etiology,clinical diagnostic criteria and therapeutic recommendations for PKD,and results of genetic analyses in PKD patients performed in domestic hospitals.Li Cao Xiaojun Huang Ning Wang Zhiying Wu Cheng Zhang Weihong Gu Shuyan Cong Jianhua Ma Ling Wei Yanchun Deng Qi Fang Qi Niu Jin Wang Zhaoxia Wang You Yin Jinyong Tian Shufen Tian Hongyan Bi Hong Jiang Xiaorong Liu Yang Lu Meizhen Sun Jianjun Wu Erhe Xu Tao Chen Tao Chen Xu Chen Wei Li Shujian Li Qinghua Li Xiaonan Song Ying Tang Ping Yang Yun Yang Min Zhang Xiong Zhang Yuhu Zhang Ruxu Zhang Yi Ouyang Jintai Yu Quanzhong Hu Qing Ke Yuanrong Yao Zhe Zhao Xiuhe Zhao Guohua Zhao Furu Liang Nan Cheng Jianhong Han Rong Peng Shengdi Chen Beisha Tang 2021Translational Neurodegeneration2021,10,1:1
