2Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children.Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao 2020World Journal of Pediatrics2020,16,3:56
3Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment.Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu 2020Acta Pharmacologica Sinica2020,41,9:32

5Clinical characteristics of fatal and recovered cases of coronavirus disease 2019 in Wuhan,China:a retrospective study显示文摘Background:The 2019 novel coronavirus has caused the outbreak of the acute respiratory disease in Wuhan,Hubei Province of China since December 2019.This study was performed to analyze the clinical characteristics of patients who succumbed to and who recovered from 2019 novel coronavirus disease(COVID-19).Methods:Clinical data were collected from two tertiary hospitals in Wuhan.A retrospective investigation was conducted to analyze the clinical characteristics of fatal cases of COVID-19(death group)and we compare them with recovered patients(recovered group).Continuous variables were analyzed using the Mann-WhitneyU test.Categorical variables were analyzed byχ2 test or Fisher exact test as appropriate.Results:Our study enrolled 109 COVID-19 patients who died during hospitalization and 116 recovered patients.The median age of the death group was older than the recovered group(69[62,74]vs.40[33,57]years,Z=9.738,P<0.001).More patients in the death group had underlying diseases(72.5%vs.41.4%,χ2=22.105,P<0.001).Patients in the death group had a significantly longer time of illness onset to hospitalization(10.0[6.5,12.0]vs.7.0[5.0,10.0]days,Z=3.216,P=0.001).On admission,the proportions of patients with symptoms of dyspnea(70.6%vs.19.0%,χ2=60.905,P<0.001)and expectoration(32.1%vs.12.1%,χ2=13.250,P<0.001)were significantly higher in the death group.The blood oxygen saturation was significantly lower in the death group(85[77,91]%vs.97[95,98]%,Z=10.625,P<0.001).The white blood cell(WBC)in death group was significantly higher on admission(7.23[4.87,11.17]vs.4.52[3.62,5.88]×109/L,Z=7.618,P<0.001).Patients in the death group exhibited significantly lower lymphocyte count(0.63[0.40,0.79]vs.1.00[0.72,1.27]×109/L,Z=8.037,P<0.001)and lymphocyte percentage(7.10[4.45,12.73]%vs.23.50[15.27,31.25]%,Z=10.315,P<0.001)on admission,and the lymphocyte percentage continued to decrease during hospitalization(7.10[4.45,12.73]%vs.2.91[1.79,6.13]%,Z=5.242,P<0.001).Alanine transaminase(22.00[15.00,34.00]vs.18.70[13.00,30.38]U/L,Z=2.592,P=0.010),aspartate transaminase(34.00[27.00,47.00]vs.22.00[17.65,31.75]U/L,Z=7.308,P<0.001),and creatinine levels(89.00[72.00,133.50]vs.65.00[54.60,78.75]μmol/L,Z=6.478,P<0.001)were significantly higher in the death group than those in the recovered group.C-reactive protein(CRP)levels were also significantly higher in the death group on admission(109.25[35.00,170.28]vs.3.22[1.04,21.80]mg/L,Z=10.206,P<0.001)and showed no significant improvement after treatment(109.25[35.00,170.28]vs.81.60[27.23,179.08]mg/L,Z=1.219,P=0.233).The patients in the death group had more complications such as acute respiratory distress syndrome(ARDS)(89.9%vs.8.6%,χ2=148.105,P<0.001),acute cardiac injury(59.6%vs.0.9%,χ2=93.222,P<0.001),acute kidney injury(18.3%vs.0%,χ2=23.257,P<0.001),shock(11.9%vs.0%,χ2=14.618,P<0.001),and disseminated intravascular coagulation(DIC)(6.4%vs.0%,χ2=7.655,P=0.006).Conclusions:Compared to the recovered group,more patients in the death group exhibited characteristics of advanced age,pre-existing comorbidities,dyspnea,oxygen saturation decrease,increased WBC count,decreased lymphocytes,and elevated CRP levels.More patients in the death group had complications such as ARDS,acute cardiac injury,acute kidney injury,shock,and DIC.Yan Deng Wei Liu Kui Liu Yuan-Yuan Fang Jin Shang Ling Zhou Ke Wang Fan Leng Shuang Wei Lei Chen Hui-Guo Liu 2020Chinese Medical Journal2020,,11:29
6The Reference Genome Sequence of Scutellaria baicalensis Provides Insights into the Evolution of Wogonin Biosynthesis显示文摘Scutellaria baicalensis Georgi is important in Chinese traditional medicine where preparations of dried roots,'Huang Qin,' are used for liver and lung complaints and as complementary cancer treatments. We report a high-quality reference genome sequence for S. baicalensis where 93% of the 408.14-Mb genome has been assembled into nine pseudochromosomes with a super-N50 of 33.2 Mb. Comparison of this sequence with those of closely related species in the order Lamiales, sesamum indicum and Salvia splendens,revealed that a specialized metabolic pathway for the synthesis of 4'-deoxyflavone bioactives evolved in the genus Scu-tellaria. We found that the gene encoding a specific cinnamate coenzyme A ligase likely obtained its newfunc- tion following recent mutations, and that four genes encoding enzymes in the 4'-deoxyflavone pathway are present as tandem repeats in the genome of S. baicalensis. Further analyses revealed that gene duplications, segmental duplication, gene amplification, and point mutations coupled to gene neo- and subfunctionaliza-tions were involved in the evolution of 4'-deoxyflavone synthesis in the genus Scutellaria. Our study not only provides significant insight into the evolution of specific flavone biosynthetic pathways in the mint family, Lamiaceae, but also will facilitate the development of tools for enhancing bioactive productivity by metabolic engineering in microbes or by molecular breeding in plants. The reference genome of S. baicalensis is also useful for improving the genome assemblies for other members of the mint family and offers an important foundation for decoding the synthetic pathways of bioactive compounds in medicinal plants.Qing Zhao Jun Yang Meng-Ying Cui Jie Liu Yumin Fang Mengxiao Yan Wenqing Qiu Huiwen Shang Zhicheng Xu Reheman Yidiresi Jing-Ke Weng Tomas Pluskal Marielle Vigouroux Burkhard Steuernagel Yukun Wei Lei Yang Yonghong Hu Xiao-Ya Chen Cathie Martin 2019Molecular Plant2019,12,7:23
7A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield.Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian 2020Molecular Plant2020,13,6:23
8The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China.Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao 2016Translational Neurodegeneration2016,5,1:23
9Successful treatment of patients with paraquat intoxication:three case reports and review of the literature显示文摘Objective: To report on three patients with paraquat (PQ) intoxication surviving after combined therapy with hemoperfusion (HP), cyclophosphamide (CTX), and glucocorticoid. Methods: Three patients suffered acute renal failure in a few days after ingesting a lethal amount of PQ. Chest computed tomography (CT) scans revealed obvious pulmonary inflammation, pleural effusion, and fibrous lesions several days after ingestion. HP was performed immediately, followed by large doses of glucocorticoid (methylprednisolone, 500 g/d) and CTX (approximately 4 g). Results: After 50 d of treatments, all three patients were discharged in healthy condition, with chest CT showing small fibrous lesions, exuda- tion, and both lungs clear of auscultation. Conclusions: The protective effect of the lungs may have been due to timely treatment at adequate doses.Qin ZHANG Wei-zhen WU Yuan-qiang LU Jie-zan WANG An-dong SHANG Feng YAO Yan CHEN 2012Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,5:20

11Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot.Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia 2021Burns & Trauma2021,9,1:17
12Seasonal pattern of Echinococcus re-infection in owned dogs in Tibetan communities of Sichuan, China and its implications for control显示文摘Background:Human cystic echinococcosis(CE)and alveolar echinococcosis(AE)are highly endemic in Tibetan communities of Sichuan Province.Previous research in the region indicated that domestic dog was the major source of human infection,and observations indicated that domestic dog could have more access to intermediate hosts of Echinococcus spp.:both domestic livestock(CE)viscera and small mammals(AE),in early winter and again in spring.We hypothesized that there would therefore be a significant increase in the risk of canine infection with Echinococcus spp.in these two seasons and conducted a reinfection study to investigate this further.Methods:Faecal samples were collected from owned dogs in seven townships in Ganze Tibetan Autonomous Prefecture(Sichuan Province,China),and Echinococcus spp.infection status was determined using copro-antigen ELISA.Dogs were sampled in April(spring),July(early summer),September/October(autumn/early winter)and December(winter)in 2009;and in April(spring)2010.Dogs were treated with praziquantel following each of the five sample collections to eliminate any tapeworms.Information on dog sex,age and body weight was also collected.The t-test,Fisher’s exact test,Poisson regression and logistic regression were used to compare means and prevalences,and to identify factors associated with infection status.Results:The proportion of female dogs was significantly lower than that of male dogs;female dogs had significantly higher(22.78%)baseline copro-ELISA prevalence than males(11.88%).Dog body weight,sex,age,county and previous infection status at any sampling point had no influence on the re-infection prevalence in general.Poisson regression did not found a significant influence on the re-infection prevalence due to different deworming/sampling time spans.Dogs exhibited significantly higher re-infection prevalences in spring and early summer of 2009 and in early winter between September/October and December of 2009,suggesting a higher infection pressure in these seasons comparing with other seasons.Conclusion:Following praziquantel treatment,dog body weight,sex,age,county,deworming time span and previous infection status at any sampling point had no influence on the re-infection prevalence in the region in general.The differences between re-infection prevalences were probably due to the seasonality in Echinoccocus spp.infection pressure in the region.Early winter,spring and early summer should be important seasons for optimal dog deworming intervention in these Tibetan communities.Qian Wang Wen-Jie Yu Bo Zhong Jing-Ye Shang Liang Huang Alexander Mastin Renqingpengcuo Yan Huang Guang-Jia Zhang Wei He Patrick Giraudoux Wei-Ping Wu Philip S.Craig 2016Infectious Diseases of Poverty2016,5,1:15
13Western medication plus Traditional Chinese Medicine preparations in patients with chronic heart failure:a prospective,single-blind,randomized,controlled,and multicenter clinical trial显示文摘OBJECTIVE: To assess the efficacy and safety in patients with chronic heart failure(CHF) of Western medication plus Traditional Chinese Medicine(TCM) preparations.METHODS: This prospective, single-blind, randomized, controlled, and multicenter clinical trial began on September 17, 2008, and was completed on June 25, 2011. A total of 340 inpatients, aged 40-79 years, with exacerbating CHF from 10 hospitals were enrolled and randomly allocated within 24 h of admission. The trial included three intervention periods. During hospitalization, the control group received western medication for CHF and the treatment group received Danhong injection with Shenfu injection or Shenmai injection. After discharge,all patients were treated with Qiliqiangxin capsules and Buyiqiangxin tablets or a placebo for 6 months. After the 6-month intervention, both groups received only continuous western medication. The primary endpoint was all-cause mortality.The efficacy assessments were as follows: B-type natriuretic peptide(BNP), Lee's HF score, the 6-minute walking test(6 MWT), left ventricular ejection fraction(LVEF), and the Minnesota Living with Heart Failure Questionnaire(MLHFQ). The safety assessments were as follows: blood and urine routine examination, hepatic and renal function, electrolytes in blood and adverse events.RESULTS: Compared with the control group, the treatment group showed a 30.99% reduction in all-cause mortality and an improved survival rate.The treatment group showed greater improvement in 6 MWT(P = 0.02) than the control group on discharge, after 12-month follow-up, there was a time-group interaction for MLHFQ(P = 0.03). Incidence rate of adverse events and other relevant safety indexes were not statistically significant between the two groups.CONCLUSION: Western medication plus TCM treatment can increase 6-minute walking distance(improve exercise tolerance) and quality of life with heart failure patients.Wang Xianliang Hou Yazhu Mao Jingyuan Zhao Yingqiang Niu Tianfu Yuan Ruyu Wang Yonggang Cui Jin-rong Shi Le Jia Xiuli Fan Ruihong Lin Qian Zhang Yan Li Zhijun Shang Hongcai Wang Baohe Wang Hongwu Wang Henghe Cui Xiaolei Soh Shanbin Ruan Jishou Zhang Boli 2017Journal of Traditional Chinese Medicine2017,37,6:15

15Novel and potent inhibitors targeting DHODH are broad-spectrum antivirals against RNA viruses including newly-emerged coronavirus SARS-CoV-2显示文摘Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide,such as the on-going outbreak of the novel coronavirus SARS-CoV-2.Herein,we identified two potent inhibitors of human DHODH,S312 and S416,with favorable drug-likeness and pharmacokinetic profiles,which all showed broad-spectrum antiviral effects against various RNA viruses,including influenza A virus,Zika virus,Ebola virus,and particularly against SARS-CoV-2.Notably,S416 is reported to be the most potent inhibitor so far with an EC5o of 17 nmol/L and an SI value of 10,505.88 in infec-ted cells.Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells.This work demonstrates that both S312/S416 and old drugs(Leflunomide/Teriflunomide)with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide,no matter such viruses are mutated or not.Rui Xiong Leike Zhang Shiliang Li Yuan Sun Minyi Ding Yong Wang Yongliang Zhao Yan Wu Weijuan Shang Xiaming Jiang Jiwei Shan Zihao Shen Yi Tong Liuxin Xu Yu Chen Yingle Liu Gang Zou Dimitri Lavillete Zhenjiang Zhao Rui Wang Lili Zhu Gengfu Xiao Ke Lan Honglin Li Ke Xu 2020Protein & Cell2020,11,10:14
16Advancing application of mesenchymal stem cell-based bone tissue regeneration显示文摘Reconstruction of bone defects,especially the critical-sized defects,with mechanical integrity to the skeleton is important for a patient's rehabilitation,however,it still remains challenge.Utilizing biomaterials of human origin bone tissue for therapeutic purposes has provided a facilitated approach that closely mimics the critical aspects of natural bone tissue with regard to its properties.However,not only efficacious and safe but also costeffective and convenient are important for regenerative biomaterials to achieve clinical translation and commercial success.Advances in our understanding of regenerative biomaterials and their roles in new bone formation potentially opened a new frontier in the fast-growing field of regenerative medicine.Taking inspiration from the role and multicomponent construction of native extracellular matrix(ECM)for cell accommodation,the ECM-mimicking biomaterials and the naturally decellularized ECM scaffolds were used to create new tissues for bone restoration.On the other hand,with the going deep in understanding of mesenchymal stem cells(MSCs),they have shown great promise to jumpstart and facilitate bone healing even in diseased microenvironments with pharmacology-based endogenous MSCs rescue/mobilization,systemic/local infusion of MSCs for cytotherapy,biomaterials-based approaches,cell-sheets/-aggregates technology and usage of subcellular vesicles of MSCs to achieve scaffolds-free or cell-free delivery system,all of them have been shown can improve MSCsmediated regeneration in preclinical studies and several clinical trials.Here,following an overview discussed autogenous/allogenic and ECM-based bone biomaterials for reconstructive surgery and applications of MSCsmediated bone healing and tissue engineering to further offer principles and effective strategies to optimize MSCs-based bone regeneration.Fengqing Shang Yang Yu Shiyu Liu Leiguo Ming Yongjie Zhang Zhifei Zhou Jiayu Zhao Yan Jin 2021Bioactive Materials2021,6,3:13

19Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants.

20Responses of wheat seedlings to cadmium,mercury and trichlorobenzene stresses显示文摘The molecular response of wheat(Triticum aestivum L.,cv.Yangmai 13) seedlings to heavy metal(Cd,Hg) and 1,2,4-trichlorobenzene(TCB) stresses were examined by two-dimensional gel electrophoresis,image analysis,and peptide mass fingerprinting.The results showed inhibitions of root and shoot growth by Cd,Hg,and TCB.These stresses led to water deficit and lipid phosphorylation in the seedling which also promoted protein phophorylation in the leaves.Hg stress inhibited protein synthesis while Cd and TCB stresses induced or up-regulated more proteins in the leaves.Most of these induced proteins played important roles in the biochemical reactions involved in tolerance of wheat to Cd and TCB stresses.The primary functions of Cd-and TCB-induced proteins included methionine metabolism,Rubisco modification,protein phosphorylation regulation,protein configuration protection,H+ transmembrane transportation and also the synthesis of ethylene,defense substances and cell wall compounds.GE Cailin DING Yan WANG Zegang WAN Dingzhen WANG Yulong SHANG Qi LUO Shishi 2009Journal of Environmental Sciences2009,21,6:12
