1Mars Express tracking and orbit determination trials with Chinese VLBI network显示文摘With strong support from European Space Agency (ESA),Shanghai Astronomical Observatory (SHAO) organized a tracking and orbit determination trails using Chinese VLBI Network (CVN) to track Mars Express,the first Mars probe launched by ESA. Using a high-resolution VLBI software correlator and Doppler measurement system developed in-house,two sets of tracking data,VLBI and Doppler,were acquired. The trials represent the first successful foray held in China to track a probe about 360 million kilometers away from the Earth. The tracking data are analyzed using a Mars satellite orbit determination software system developed at SHAO. The results show that the accuracy of 5 s integrated three-way-Doppler data is about 0.3 mm/s,or roughly the same accuracy as ESA's tracking data. Position discrepancies between the Doppler-based orbit solution of 8 h arc-length (about 1 orbital revolution) and ESA's reconstructed orbit are of the order of several hundred meters. In preparing for the Russia-China co-sponsored Mars exploration mission Phobos-Grunt-YingHuo,simulations were carried out to evaluate the achievable orbital accuracy levels and the contributions of VLBI and Doppler data respectively. Results show that Doppler data provide better orbit accuracy,so that for VLBI to be able to provide kilometer level orbit solutions,the accuracy of VLBI measurement needs to be improved by at least one order of magnitude.CAO JianFeng HUANG Yong HU XiaoGong MA maoLi ZHENG WeiMin 2010Chinese Science Bulletin2010,55,32:14
2BENIGN PAROXYSMAL POSITIONAL VERTIGO显示文摘One of the most common causes of vertigo is Benign Paroxysmal Positional Vertigo(BPPV),a sensation of spinning that is caused by a sudden change in head position.This type of vertigo was first described by Robert Barany in the early 1920s[1].He suggested that BPPV was caused by abnormal otoliths,also called statoconium or otoconius,a structure in the saccule or utricleJohan Bergenius ZHANG Qing DUAN Maoli 2014Journal of Otology2014,9,1:5
3Agricultural reclamations in Xiliao River Valley, China since the Holocene显示文摘自从 Holocene,在 Xiliao 河山谷的农业开垦从草地导致了一个巨大的风景变化到农田。在这份报纸,我们由自从 Qing 王朝,在史前, Liao-Jin 王朝和时期分析三主要农业开垦在 Xiliao 河山谷重新考虑人陆地关系。我们主张当人口统计的压力出现在这个区域时,特别在最后开垦期间, intraregional 迁居(第二迁居) 是主要反应减轻如此的压力,它也区分二个不同解决地点:起始的区域和第二等的区域。由于这二个区域之间的环境差别,一个人引起了更多的严肃的骚乱到本地环境的后者上的耕作。因此,第二等的区域成为了严重需要环境管理的关键区域。HAN Maoli ZHAO Yuhui ZHANG Dan 2012Journal of Geographical Sciences2012,22,2:2

5A comparison of effects of systemic and intratympanic steroid therapies for sudden sensorineural hearing loss:A meta-analysis显示文摘Objective:To evaluate the efficacy and safety of intratympanic and systemic steroid therapies in the initial treatment of Sudden Sensorineural Hearing Loss(SSNHL) patients.Methods:A comprehensive search of PubMed,Wanfang database and CNKI(China National Knowledge Infrastructure) was performed covering the period from January 1990 to July 2014.A meta-analysis was conducted after filtering by the criteria of Cochrane Collaboration.Three hundred fifty six subjects in nine studies allocated to the group of intratympanic steroid therapies and 343 controls receiving systemic steroid therapies met the criteria for meta-analysis.The data were extracted and analyzed using the Rev Man 5.3 meta-analysis software.Results:The total effectiveness rate in SSNHL patients receiving intratympanic steroid therapies did not differ statistically from patients receiving systemic therapies(RR = 1.08,95%CI = 0.99-1.99,P = 0.10),although the rate of full hearing recovery in this group differed significantly from patients receiving systemic therapies(RR = 1.29,95%CI = 1.00-1.66,P = 0.05).Conclusion:Local steroid therapy appears to generate higher rate of complete hearing recovery than systemic steroid treatment as an initial treatment for SSNHL,which may be especially useful for patients in whom systemic steroids are contraindicated.Dan Zhao Busheng Tong Qiang Wang Sten Hellstrom Maoli Duan 2016Journal of Otology2016,11,1:1

10Research Progress of Polygonatum Germplasm Resources in China显示文摘Polygonatum is a traditional and precious Chinese medicine in China,as well as a traditional medicinal and food homologous material.It has a long history of cultivation and medicinal use.It not only has the effects of boosting qi and nourishing yin,nourishing the spleen and lungs,and tonifying the kidney,but also application value in food,health products,ornamental,cosmetics,etc.There are many varieties of Polygonatum resources all over China,which are easy to be mixed.There are three species of medicinal Polygonatum recorded in the 2015 edition of Pharmacopeia of the People s Republic of China.In order to sustainably use and fully develop Polygonatum medicinal resources,we conducted textual research on relevant data and research on the distribution of Polygonatum resources,germplasm identification,genetic diversity and breeding research,so as to provide a reference for the selection and breeding of polygonatum,artificial cultivation and the development and utilization of potential Polygonatum resources and for the solution of the contradiction between supply and demand in the Polygonatum market.Kuoshu CUI Te XIAO Huiping LI Aaqil KHAN George BAWA Guopeng CHEN Teng PENG Bin LI Wenyu YANG Benchuan ZHENG Maoli WU Zhilai ZHAN 2021Agricultural Biotechnology2021,10,5:0
11THE GENETIC-INDUCED HEARING lOSS CAN BLOCK THE EFFECT OF NOISE TRAUMA IN WAlTZING GUINEA PIG显示文摘The waltzing guinea pig may be a good model to investigate if genetic factor can change the sensitivity in noise-induced hearing loss.A total of 34 waltzig guinea pigs were studied and we found that there is no any significant increased sensitivity to noise trauma if the age-induced hearing loss was considered in waltzing guinea pig.Tong Busheng Duan Maoli 2013Journal of Otology2013,8,1:0
124~7岁儿童梅尼埃病显示文摘本文对4例4~7岁开始患病且具有梅尼埃病症状的患儿临床数据和听-前庭检查结果进行回顾性综述,所有患儿均从较早年龄开始有自发性复发性(旋转性)眩晕、波动性低频感音神经性听力下降症状,可明确诊断为梅尼埃病。由于年龄较小,不能表达听觉症状,起初患儿并不符合梅尼埃病的诊断要求,但至其8岁时,4例患儿均主诉耳鸣和(或)患侧耳胀满感,因此符合美国耳鼻咽喉科学会(AAO)梅尼埃病诊断标准。即使缺乏主观听觉症状的信息,对具有特发性自发性复发性眩晕、听力图为波动性低频听力损失的幼儿仍可考虑为梅尼埃病。本报告提示梅尼埃病也可发生在幼儿。KRISTER BRANTBERG MAOLI DUAN BABAK FALAHAT 刘波 张甦琳 孔维佳 2014临床耳鼻咽喉头颈外科杂志2014,28,7:0
13Study on the Themal Conductivity of Compacted Buffer/Backfill Materials显示文摘The thermal property is one of the key properties for the design of the high-level radioactive waste (HLW) repository. In this study, the thermal properties transient automatic tester (HPP-F) is uesd to study the thermal conductivity of multiphase composite buffer/backfill material including the type B-Z and B-Z-P (Here B、Z、P represents bentonite、zeolite and pyrite respectively,the same as in the following.) in different dry density and moisture conditions. The results show that for the same moisture content (dry density), thermal conductivity of specimens increases as the dry density (moisture content) increases. As a result, the type B-Z-P which is highly compacted of 1.8 g/cm3 in dry density and 17.65% in moisture content performs well, it meets the requirements of the IAEA and is easy to be compacted ,so it can be recommend as a alternative material of high level radioactive waste disposal repository buffer/backfilling materials.WANG Maoli YI Facheng WANG Zhe WAN Zhongyan WANG Chong WANG Jianwei 2013矿物学报2013,33,S1:0
14Effect of auditory stress agents on heterozygous German waltzing guinea pigs显示文摘The German waltzing guinea pig is a strain of animals expressing deafness and severe balance disorders at birth.The mutation arose spontaneously in a breeding facility in Germany and as the affected animals show a characteristic waltzing behavior,the strain is named the German waltzing guinea pig.The strain is presently bred only at Karolinska Institutet.The hereditary inner ear impairment has a recessive mode of inheritance and the strain thus produces not only affected homozygotes but also symptom-free heterozygotes and fully normal offspring.The outcome depends solely on the genotype of the parents.The heterozygotes,which have obtained the 'waltzing' gene from one parent only,have normal hearing and no balance dysfunction.The heterozygous animals appear normal but will,in turn,carry the genetic defect to the next generation.The present thesis is focused on these animals.Noise and ototoxic drugs are well known stress factors that interfere negatively with the hearing organ in both humans and animals,causing hearing impairment.However,the inter-individual variability in susceptibility to auditory stress factors is surprisingly large,most likely due to different genetic predisposition.In this study,heterozygous animals of the German waltzing guinea pig,animals carrying a genetic defect known to cause severe hearing impairment,were used to study how an unexplored gene for deafness interacts with auditory stress agents,i.e.noise exposure and the ototoxic drugs gentamicin and cisplatin.Animals were exposed to both narrowband as well as broadband noise at different ages and hearing thresholds were measured using ABRs.Heterozygotes of the German waltzing guinea pig showed less threshold shifts compared to control strains.Older animals were less affected by the noise trauma than younger animals.To test the hypothesis that the efferent system contributes to protection of the inner ear against noise trauma,measurements using a new method of post onset adaptation of DPOAEs and maximum adaptation magnitude were conducted.The post onset adaptation of DPOAEs detected a strain difference at the higher frequency region while in the maximum adaptation magnitude method showed no difference between the strains.The heterozygous German waltzing guinea pigs displayed a distinctly increased resistance to noise exposures,manifested as reduced threshold shifts and faster recovery following acoustic overstimulation.However,when exposed to ototoxic drugs,the heterozygous carriers suffered from a more pronounced hearing loss.It is concluded that endogenous resistance to noise in the heterozygotes does not offer any protection against ototoxic drugs.The detailed mechanisms remain to be explored.sa Skjnsberg Maoli Duan Ann-Christin Johnson Mats Ulfendahl 2014Journal of Otology2014,9,4:0
