22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54

5Fields of applications,diagnostic yields and findings of OMOM capsule endoscopy in 2400 Chinese patients显示文摘AIM:To retrospectively analyze the fields of application,diagnostic yields and findings of OMOM capsule endoscopy in Chinese patients.METHODS:A database including 2400 Chinese patients who received OMOM capsule endoscopy in 27 endoscopy centers in China was retrieved from the Jianshan Science and Technology Ltd.OMOM capsule endoscopy database.The patient's age,gender,fields of application,the potentially relevant findings,pyloric transit time(PTT),small bowel transit time(SBTT),and complete small-bowel examination rate(CSER) were recorded and analyzed.RESULTS:Two thousand four hundred patients aged 9-91 years(mean,49 years),of whom 1510 were males(62.9%),underwent 2400 OMOM capsule endoscopy procedures.One thousand two hundred and thirty two(51.3%) were referred with obscure gastrointestinal bleeding(OGIB),642(26.8%) with abdominal pain,and 223(9.3%) with chronic diarrhea.The overall diagnostic yield was 47.7%(1144/2400).The diagnostic yield of OMOM capsule endoscopy in OGIB subgroup was much higher than in the non-OGIB subgroup(62.4% vs 32.1%,P<0.001).The most common findings of the small bowel in Chinese patients with OGIB were arteriovenous malformation(28.1%) and tumors(18.9%).There was no significant difference in the diagnostic yield between the male and female patients with OGIB.However,the diagnostic yield in patients aged more than 60 was higher than in patients aged less than 60(69.8% vs 58.9%,P<0.001).The median PTT was 41 min(range:1-544 min) and the mean SBTT was 247.2 ± 88.9 min.The overall CSER was 86.8%.CONCLUSION:The OMOM capsule endoscopy is a valuable tool for small bowel evaluation with good overall diagnostic yield and CSER.Liao, Zhuan Gao, Rui Li, Feng Xu, Can Zhou, Yi Wang, Jin-Shan Li, Zhao-Shen 2010World Journal of Gastroenterology2010,16,21:35
6Effects of Long-Term Winter Planted Green Manure on Physical Properties of Reddish Paddy Soil Under a Double-Rice Cropping System显示文摘Soil physical properties are important indicators of the potential for agricultural production.Our objective was to evaluate the effects of long-term inputs of green manures on physical properties of a reddish paddy soil(Fe-Typic Hapli-Stagnic Anthrosols) under a double cropping system.The common cropping pattern before the study was early-late rice-fallow(winter).The field treatments included rice-rice-fallow(R-R-WF),rice-rice-rape(R-R-RP),rice-rice-Chinese milk vetch(RR-MV),and rice-rice-ryegrass(R-R-RG).The rape,Chinese milk vetch and ryegrass were all incorporated as green manures 15 d before early rice transplanting during the following year.The soil bulk density in all green manure treatments was significantly reduced compared with the winter fallow treatment.Soil porosity with green manure applications was significantly higher than that under the winter fallow.The green manure treatments had higher 0.25-5 mm water stable aggregates and aggregates stabilities in the plow layer(0-15 cm depth) compared with the fallow treatment.The mean weight diameter(MWD) and normalized mean weight diameter(NMWD) of aggregates in the green manure treatment were larger than that with the winter fallow.Soil given green manure retained both a higher water holding capacity in the plow layer soil,and a larger volume of moisture at all matric potentials(-10,-33 and-100 kPa).We conclude that the management of double-rice fields in southern central China should be encouraged to use green manures along with chemical fertilizers to increase SOC content,improve soil physical properties and soil fertility.YANG Zeng-ping XU Ming-gang ZHENG Sheng-xian NIE Jun GAO Ju-sheng LIAO Yu-lin XIE Jian 2012Journal of Integrative Agriculture2012,11,4:40

13YTH Domain: A Family of N^6-methyladenosine (m^6A) Readers显示文摘Like protein and DNA, different types of RNA molecules undergo various modifications. Accumulating evidence suggests that these RNA modifications serve as sophisticated codes to mediate RNA behaviors and many important biological functions. N^6-methyladenosine(m^6 A)is the most abundant internal RNA modification found in a variety of eukaryotic RNAs, including but not limited to m RNAs, t RNAs, r RNAs, and long non-coding RNAs(lnc RNAs). In mammalian cells, m^6 A can be incorporated by a methyltransferase complex and removed by demethylases, which ensures that the m^6 A modification is reversible and dynamic. Moreover, m^6 A is recognized by the YT521-B homology(YTH) domain-containing proteins, which subsequently direct different complexes to regulate RNA signaling pathways, such as RNA metabolism, RNA splicing, RNA folding, and protein translation. Herein, we summarize the recent progresses made in understanding the molecular mechanisms underlying the m^6 A recognition by YTH domaincontaining proteins, which would shed new light on m^6 A-specific recognition and provide clues to the future identification of reader proteins of many other RNA modifications.Shanhui Liao Hongbin Sun Chao Xu 2018Genomics, Proteomics & Bioinformatics2018,16,2:29

17Effects of organic acids on the leaching process of ion-adsorption type rare earth ore显示文摘To examine the activation of organic acids on the leaching process of ion-adsorption type rare earth ore(IRE-ore), the leaching behavior of rare earth(RE) and zeta potential of IRE-ore were investigated in the absence and presence of carboxylic acids. The results show that all the tested organic acids(acetic acid,malonic acid, citric acid, tartaric acid, succinic acid, and malic acid) can promote RE extraction. At relatively high concentrations of organic acids, the activation efficiency of organic acids on RE extraction is generally consistent with their complexation ability; whereas at their low concentrations, the change of zeta potential on the IRE-ore surface with organic acid concentration and p H has a close association with RE extraction, which indicates that organic acids can impact the surface electrical property of IREore via their adsorption/desorption, and thereby increase/decrease the affinity of RE ions to IRE-ore.Therefore the influence of organic acids on the IRE-ore surface electrical property also plays an important role in RE extraction in addition to their complexation with RE ions.Li Wang Chunfa Liao Youming Yang Haibo Xu Yanfei Xiao Chunhua Yan 2017Journal of Rare Earths2017,35,12:23
18Crop Insurance, Premium Subsidy and Agricultural Output显示文摘This paper studied the effects of crop insurance on agricultural output with an economic growth model. Based on RamseyCass-Koopmans(RCK) model, a basic model of agriculture economic growth was developed. Extending the basic model to incorporate uncertainty and insurance mechanism, a risk model and a risk-insurance model were built to study the influences of risk and crop insurance on agricultural output. Compared with the steady states of the three models, the following results are achieved:(i) agricultural output decreases if we introduce uncertainty into the risk-free model;(ii) crop insurance promotes agriculture economic growth if insurance mechanism is introduced into the risk model;(iii) premium subsidy constantly improves agricultural output. Our contribution is that we studied the effects of crop insurance and premium subsidy from the perspective of economic growth in a dynamic framework, and proved the output promotion of crop insurance theoretically.XU Jing-feng LIAO Pu 2014Journal of Integrative Agriculture2014,13,11:21
19Nedaplatin/Gemcitabine Versus Carboplatin/Gemcitabine in Treatment of Advanced Non-small Cell Lung Cancer: A Randomized Clinical Trial显示文摘Objective: To evaluate the efficacy and safety of nedaplatin/gemcitabine (NG) and carboplatin/gemcitabine (CG) in the management of untreated advanced non‐small cell lung cancer (NSCLC). Methods: Sixty‐two patients with previously untreated advanced NSCLC were recruited between June 2006 and November 2007. Subjects were randomly assigned to the NG arm (n=30) and the CG arm (n=32). Only patients (24 and 25 in the NG and CG arms, respectively) who completed ≥2 chemotherapy cycles were included in the data analysis. The primary outcome measure was the objective response rate (ORR). The secondary outcome measures included progression‐free survival (PFS), overall survival (OS) and adverse events. Results: There were no statistically significant differences in the efficacy measures (ORR, P=0.305; median PFS, P=0.198; median OS, P=0.961) or in the major adverse events (grade 3/4 neutropenia, P=0.666; grade 3/4 anemia, P=0.263; grade 3/4 thrombocytopenia, P=0.212) between the two treatment arms. However, there was a trend towards higher ORR (37.5% vs. 24.0%), longer PFS (6.0 vs. 5.0 months), and less adverse events in the NG arm. Conclusion: NG regimen seems to be superior over CG regimen for advance NSCLS, but further investigation is needed to validate this superiority.Jin-ji Yang Qing Zhou Ri-qiang Liao Yi-sheng Huang Chong-rui Xu Zhen Wang Bin-chao Wang Hua-jun Chen Yi-long Wu 2012Chinese Journal of Cancer Research2012,24,2:18
20Increased brachial-ankle pulse wave velocity is associated with impaired endothelial function in patients with coronary artery disease显示文摘Background Pulse wave velocity and flow-mediated vasodilation (FMD) are widely used as noninvasive modalities for evaluating atherosclerosis. However, it is not known whether pulse wave velocity is related to FMD in patients with coronary artery disease (CAD). Therefore, the present study was designed to investigate the alteration in brachial-ankle pulse wave velocity (baPWV) and endothelial function in CAD patients. Methods Thirty-three patients with CAD and thirty control subjects were recruited for this study. baPWV was measured non-invasively using a VP 1000 automated PWV/ABI analyzer (PWV/ABI, Colin Co. Ltd., Komaki, Japan). Endothelial function as reflected by FMD in the brachial artery was assessed with a high-resolution ultrasound device. Results baPWV was increased in CAD patients compared with control subjects [(1756.1±253.1) cm/s vs (1495.3±202.3) cm/s, P<0.01]. FMD was significantly reduced in CAD patients compared with control subjects [(5.2±2.1) % vs (11.1±4.4) %, P<0.01]. baPWV correlated with FMD (r =-0.68, P<0.001). The endothelium-independent vasodilation induced by sublingual nitroglycerin in the brachial artery was similar in the CAD group compared with the control group.

Our data therefore suggest that baPWV can be used as a noninvasive surrogate index in clinical evaluation of endothelial function.LIU Dong-hong WANG Yan LIAO Xin-xue XU Ming-guo WANG Jie-mei YANG Zhen CHEN Long LU Ming-de LU Kun TAO Jun 2006Chinese Medical Journal2006,,22:17
