| 3 | 2018 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 | 2018 | Science Bulletin2018，63，23： | 54 |
| 4 | Get effective polyclonal antisera in one month显示文摘According to the traditional immunization procedure, after the first injection of the sample A (emulsion of aimed antigen and Freund's complete adjuvant) to immunize rabbit, successive injections of the sample B (emulsion of aimed antigen and Freund's incomplete adjuvant) were followed every 2-4 weeks. In general,high titer of the corresponding polyclonal antisera will be observed after 4-5 injections of sample B in 3-4months. This report presents a simply modified procedure that was able to stimulate the antisera formation in one month and achieve enough avidity to satisfy either Western blot or immunohistochemistry analysis.It just applied an additional injection of the sample A to the rabbit at the 3rd day after the primary immunization injection. You could gain the high titer of the antisera right after the first sample B injection in one month.

| 7 | Effect of viscosity,basicity and organic content of composite flocculant on the decolorization performance and mechanism for reactive dyeing wastewater显示文摘A coagulation/flocculation process using the composite flocculant polyaluminum chloride-epichlorohydrin dimethylamine (PACEPI-DMA) was employed for the treatment of an anionic azo dye (Reactive Brilliant Red K-2BP dye).The effect of viscosity (η),basicity (B=[OH]/[Al]) and organic content (WP) on the flocculation performance as well as the mechanism of PAC-EPI-DMA flocculant were investigated.The η was the key factor affecting the dye removal efficiency of PAC-EPI-DMA.PAC-EPI-DMA with an intermediate η (2400 mPa·sec) gave higher decolorization efficiency by adsorption bridging and charge neutralization due to the co-effect of PAC and EPI-DMA polymers.The W P of the composite flocculant was a minor important factor for the flocculation.The adsorption bridging of PAC-EPI-DMA with η of 300 or 4300 mPa·sec played an important role with the increase of W P,whereas the charge neutralization of them was weaker with the increase of W P.There was interaction between W P and B on the removal of reactive dye.The composite flocculant with intermediate viscosity and organic content was effective for the treatment of reactive dyeing wastewater,which could achieve high reactive dye removal efficiency with low organic dosage. | Yuanfang Wang Baoyu Gao Qinyan Yue Yan Wang | 2011 | Journal of Environmental Sciences2011，23，10： | 33 |
| 8 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016，29，1： | 29 |
| 9 | Astragalus polysaccharide attenuates rat experimental colitis by inducing regulatory T cells in intestinal Peyer's patches显示文摘AIM: To explore probable mechanism underlying the therapeutic effect of Astragalus polysaccharide(APS) against experimental colitis.METHODS: Thirty-two Sprague-Dawley rats were randomly divided into four groups. Colitis was induced with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS). The rats with colitis were treated with 400 mg/kg of APS for 7 d. The therapeutic effect was evaluated by colonic weight, weight index of the colon, colonic length, and macroscopic and histological scores. The levels of regulatory T(Treg) cells in Peyer's patches were measured by flow cytometry, and cytokines in colonic tissue homogenates were analyzed using enzyme-linked immunosorbent assay. The expression of related orphan receptor-gt(ROR-gt), IL-23 and STAT-5a was measured by Western blot.RESULTS: After 7-d treatment with APS, the weight index of the colon, colonic weight, macroscopical and histological scores were decreased, while the colonic length was increased compared with the model group. The expression of interleukin(IL)-2, IL-6, IL-17, IL-23 and ROR-gt in the colonic tissues was down-regulated, but Treg cells in Peyer's patches, TGF-β and STAT5 a in the colonic tissues were up-regulated.CONCLUSION: APS effectively ameliorates TNBSinduced experimental colitis in rats, probably through restoring the number of Treg cells, and inhibiting IL-17 levels in Peyer's patches. | Hai-mei Zhao Yan Wang Xiao-Ying Huang min-fang Huang Rong Xu Hai-Yang Yue Bu-gao Zhou Hong-Yan Huang Qi-meng Sun Duan-Yong Liu | 2016 | World Journal of Gastroenterology2016，22，11： | 28 |
| 10 | Effects of penehyclidine hydrochloride in small intestinal damage caused by limb ischemia-reperfusion显示文摘AIM:To investigate the protective effect of penehyclidine hydrochloride post-conditioning in the damage to the barrier function of the small intestinal mucosa caused by limb ischemia-reperfusion(LIR) injury. METHODS:Male Wistar rats were randomly divided into three groups(36 rats each) :the sham-operation group(group S) ,lower limb ischemia-reperfusion group(group LIR) ,and penehyclidine hydrochloride postconditioning group(group PHC) .Each group was divided into subgroups(n=6 in each group) according to ischemic-reperfusion time,i.e.immediately 0 h(T1) ,1 h(T2) ,3 h(T3) ,6 h(T4) ,12 h(T5) ,and 24 h(T6) .Bilateral hind-limb ischemia was induced by rubber band application proximal to the level of the greater trochanter for 3 h.In group PHC,0.15 mg/kg of penehyclidine hydrochloride was injected into the tail vein immediately after 3 h of bilateral hind-limb ischemia.The designated rats were sacrificed at different time-points of reperfusion;diamine oxidase(DAO) ,superoxide dismutase(SOD) activity,myeloperoxidase(MPO) of small intestinal tissue,plasma endotoxin,DAO,tumor necrosis factor-α(TNF-α) ,and interleukin(IL) -10 in serum were detected in the rats. RESULTS:The pathological changes in the small intestine were observed under light microscope.The levels of MPO,endotoxin,serum DAO,and IL-10 at T1-T6,and TNF-αlevel at T1-T4 increased in groups LIR and PHC(P<0.05) compared with those in group S,but tissue DAO and SOD activity at T1-T6 decreased(P<0.05) .In group PHC,the tissue DAO and SOD activity at T2-T6,and IL-10 at T2-T5 increased to higher levels than those in group LIR(P<0.05) ;however,the levels of MPO,endotoxin,and DAO in the blood at T2-T6,and TNF-αat T2 and T4 decreased(P<0.05) . CONCLUSION:Penehyclidine hydrochloride post-conditioning may reduce the permeability of the small intestines after LIR.Its protection mechanisms may be related to inhibiting oxygen free radicals and inflammatory cytokines for organ damage. | Yan Zhang Yu-Fang Leng Xing Xue Yue Zhang Tao Wang Yu-Qing Kang | 2011 | World Journal of Gastroenterology2011，17，2： | 25 |
| 11 | Regulatory effect of a Chinese herbal medicine formula on nonalcoholic fatty liver disease显示文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)has become a major cause of chronic liver disease.The Chinese herbal medicine(CHM)Dachaihu decoction(DCHD)has been proved to treat NAFLD with good efficacy in previous studies.Based on the TCM principle of formula formation,we divided DCHD into soothing liver part,invigorating spleen part,and dredging intestine part.Marshall officially proposed the concept of“intestinal-hepatic axis”,which systematically explains the interactions between the intestine and liver.We hypothesized that the effect of CHM on NAFLD is achieved by regulating the liver and intestine.Thus,we aimed to investigate the possible effect of a CHM formula on NAFLD in a rat model.AIM To investigate the effects of a CHM formula(a decoction of Chinese thorowax root,scutellaria root,and white peony root)on NAFLD and its regulatory effect on the“intestinal-liver”axis.METHODS Sixty rats were randomly divided into control,model,pioglitazone hydrochloride(PH),and CHM(a decoction of Chinese thorowax root,scutellaria root,and white peony root)groups.An NAFLD rat model was established using a high-fat highfructose diet for 16 wk.From the 13th week,rats were administered with PH or a decoction of Chinese thorowax,scutellaria,and white peony root(CHM group)for 4 wk.Rats in the control group and model group were administered with an equal volume of distilled water.At the end of the study,blood was collected via the abdominal aorta.Liver tissues were harvested and any morphological changes were observed by hematoxylin-eosin(HE)staining,Oil red O staining,and Masson staining.In addition,blood lipids,liver function markers,and triglyceride(TG)in liver tissues were analyzed.The levels of transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),Toll-like receptor-4(TLR4),and nuclear factor-kappa B(NF-кB)in liver tissues and secreted immunoglobulin A(sIgA)in intestinal tissues were analyzed by ELISA,and protein and mRNA expression of occludin and zonula occludens-1(ZO-1)in the intestine were measured using Western blot and reverse transcriptionquantitative polymerase chain reaction,respectively.The endotoxin level in plasma was detected by endpoint chromogenic assay.RESULTS Compared to the normal control group,the liver coefficient,serum TG,total cholesterol(TC),low density lipoprotein(LDL),aspartate aminotransferase(AST),and alanine aminotransferase(ALT),blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues increased significantly in the model group,while serum high density lipoprotein(HDL),intestinal sIgA,and protein and mRNA expression of occludin and ZO-1 decreased significantly in the model group(P<0.01).PH and CHM attenuated the elevated liver coefficient,serum TG,TC,LDL,AST,and ALT,blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues and increased serum HDL levels compared to the model group(P<0.01).Intestinal sIgA and the protein and mRNA expression of intestinal occludin and ZO-1 were significantly increased in the PH group compared to the model and CHM groups(P<0.01).CONCLUSION The decoction of Chinese thorowax root,scutellaria root,and white peony root is beneficial in regulating lipid metabolism and liver function,which indicates that it has a good effect on the liver.To a certain extent,this CHM formula can affect both the liver and intestine,while its effect on the liver is superior to that on the intestine. | Jia-Min Yang Yan Sun Min Wang Xin-Lei Zhang Shu-Jing Zhang Yu-Shan Gao Lin Chen Meng-Yao Wu Lu Zhou Yu-Mei Zhou Yue Wang Feng-Jie Zheng Yu-Hang Li | 2019 | World Journal of Gastroenterology2019，25，34： | 24 |
| 12 | Comparative analysis of twenty-five compounds in different parts of Astragalus membranaceus var.mongholicus and Astragalus membranaceus by UPLC-MS/MS显示文摘As a traditional Chinese medicine,the root of Astragalus membranaceus var.mongholicus(AMM)or A.membranaceus(AM)has been widely used in China and other Asian countries for thousands of years.Till now,the flavonoids,phenolic acids and saponins are considered as the main active components contributing to their therapeutic effect in these plants.In order to clarify the distribution and contents of these compounds in different organs of these plants,a rapid and sensitive analytical method for simultaneous determination of 25 active compounds including seven types(i.e.dihydroflavones,isoflavane,isoflavones,flavones,pterocarpans,phenolic acid and saponins)within 10 min was established using ultra-pressure liquid chromatography coupled with tandem mass spectrometry(UPLCeMS/MS).Then,the established method was fully validated and successfully applied to the determination of the contents of these analytes in different parts(root,rhizome,stem,leaf and flower)of AMM and AM.The results indicated that the contents of the same type of compounds in two different species plants were significantly different.Moreover,the obvious differences were also found for the distribution and contents of different type of compounds in five organs of the same species.The present study could provide necessary information for the rational development and utilization of AMM and AM resource. | Yuan Li Sheng Guo Yue Zhu Hui Yan Da-Wei Qian Han-Qing Wang Jian-Qiang Yu Jin-Ao Duan | 2019 | Journal of Pharmaceutical Analysis2019，9，6： | 23 |
| 13 | Evaluation of the 7^(th) edition of the TNM classification in patients with resected esophageal squamous cell carcinoma显示文摘AIM:To evaluate the prognostic factors and tumor stages of the 7th edition TNM classification for esophageal cancer.METHODS:In total,1033 patients with esophageal squamous cell carcinoma(ESCC)who underwent surgical resection with or without(neo)adjuvant therapy between January 2003 and June 2012 at the Thoracic Surgery DepartmentⅡof the Beijing Cancer Hospital,Beijing,China were included in this study.The following eligibility criteria were applied:(1)squamous cell carcinoma of the esophagus or gastroesophageal junction identified by histopathological examination;(2)treatment with esophagectomy plus lymphadenectomy with curative intent;and(3)complete pathologic reports and follow-up data.Patients who underwent non-curative(R1)resection and patients who died in hospital were excluded.Patients who received(neo)adjuvant therapy were also included in thisanalysis.All patients were restaged using the 7th edition of the Union for International Cancer Control and the American Joint Committee on Cancer TNM staging systems.Univariate and multivariate analyses were performed to identify the prognostic factors for survival.Survival curves were plotted using the Kaplan-Meier method,and the log-rank test was used to evaluate differences between the subgroups.RESULTS:Of the 1033 patients,273 patients received(neo)adjuvant therapy,and 760 patients were treated with surgery alone.The median follow-up time was 51.6mo(range:5-112 mo)and the overall 5-year survival rate was 36.4%.Gender,'p T'and'p N'descriptors,(neo)adjuvant therapy,and the 7th edition TNM stage grouping were independent prognostic factors in the univariate and multivariate analyses.However,neither histologic grade nor cancer location were independent prognostic factors in the univariate and multivariate analyses.The 5-year stage-based survival rates were as follows:ⅠA,84.9%;ⅠB,70.9%;ⅡA,56.2%;ⅡB,43.3%;ⅢA,37.9%;ⅢB,23.3%;ⅢC,12.9%andⅣ,3.4%.There were significant differences between each adjacent staging classification.Moreover,there were significant differences between each adjacent p N and p M subgroup.According to the p T descriptor,there were significant differences between each adjacent subgroup except between p T3 and p T4(P=0.405).However,there was no significant difference between each adjacent histologic grade subgroup and between each adjacent cancer location subgroup.CONCLUSION:The 7th edition is considered to be valid for patients with resected ESCC.However,the histologic grade and cancer location were not prognostic factors for ESCC. | Jia Wang Nan Wu Qing-Feng Zheng Shi Yan Chao Lv Shao-Lei Li Yue Yang | 2014 | World Journal of Gastroenterology2014，20，48： | 23 |

| 15 | Isolation and Characterization of an Algicidal Bacterium Indigenous to Lake Taihu with a Red Pigment able to Lyse Microcystis aeruginosa显示文摘Objective To isolate and characterize indigenous algicidal bacteria and their algae-lysing compounds active against Microcystis aeruginosa, strains TH1, TH2, and FACHB 905. Methods The bacteria were identified using the Biolog automated microbial identification system and 16S rDNA sequence analysis. The algae-lysing compounds were isolated and purified by silica gel column chromatography and reverse-phase high performance liquid chromatography. Their structures were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectroscopy. Algae-lysing activity was observed using microscopy. Results The algae-lysing bacterium LTH-2 isolated from Lake Taihu was identified as Serratia marcescens. Strain LTH-2 secreted a red pigment identified as prodigiosin (C 20 H 25 N 3 O), which showed strong lytic activity with algal strains M. aeruginosa TH1, TH2, and FACHB 905 in a concentration-dependent manner. The 50% inhibitory concentration (IC 50 ) of prodigiosin with the algal strains was 4.8 (±0.4)×10 -2 μg/mL, 8.9 (±1.1)×10-2 μg/mL, and 1.7 (±0.1)×10 -1 μg/mL in 24 h, respectively. Conclusion The bacterium LTH-2 and its pigment had strong Microcystis-lysing activity probably related to damage of cell membranes. The bacterium LTH-2 and its red pigment are potentially useful for regulating blooms of harmful M. aeruginosa. | YANG Fei WEI Hai Yan LI Xiao Qin LI Yun Hui LI Xiao Bo YIN Li Hong PU Yue Pu | 2013 | Biomedical and Environmental Sciences2013，26，2： | 19 |

| 19 | Ge-Gen Decoction attenuates oxytocin-induced uterine contraction and writhing response: potential application in primary dysmenorrhea therapy显示文摘The uterine tetanic contraction and uterine artery blood flow reduction are possible reasons for primary dysmenorrhea(PD). In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction(GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F_2 alpha(PGF_(2α)) and Ca^(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF_(2α) and Ca^(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy. | YANG Lu CHAI Cheng-Zhi YUE Xin-Yi YAN Yan KOU Jun-Ping CAO Zheng-Yu YU Bo-Yang | 2016 | Chinese Journal of Natural Medicines2016，14，2： | 17 |
| 20 | Vortex genesis over the Bay of Bengal in spring and its role in the onset of the Asian Summer Monsoon显示文摘Physical processes associated with onset of the 1998 Asian summer monsoon were examined in detail using multi-source datasets. We demonstrated that strong ocean-atmosphere-land interaction in the northern Indian Ocean and tropical Asian area during spring is a fundamental factor that induces the genesis and development of a monsoon onset vortex over the Bay of Bengal (BOB), with the vortex in turn triggering onset of the Asian summer monsoon. In spring, strong surface sensible heating over India and the Indochina Peninsula is transferred to the atmosphere, forming prominent in situ cyclonic circulation, with anticyclonic circulations over the Arabian Sea and northern BOB where the ocean receives abundant solar radiation. The corresponding surface winds along the North Indian Ocean coastal areas cause the ocean to produce the in situ offshore currents and upwelling, resulting in sea surface temperature (SST) cooling. With precipitation on the Indochina Peninsula increasing from late April to early May, the offshore current disappears in the eastern BOB or develops into an onshore current, leading to SST increasing. A southwest-northeast oriented spring BOB warm pool with SST >31°C forms in a band from the southeastern Arabian Sea to the eastern BOB. In early May, the Somali cross-equatorial flow forms due to the meridional SST gradient between the two hemispheres, and surface sensible heat over the African land surface. The Somali flow overlaps in phase with the anticyclone over the northern Arabian Sea in the course of its inertial fluctuation along the equator. The convergent cold northerlies on the eastern side of the anticyclone cause the westerly in the inertial trough to increase rapidly, so that enhanced sensible heat is released from the sea surface into the atmosphere. The cyclonic vorticity forced by such sensible heating is superimposed on the inertial trough, leading to its further increase in vorticity strength. Since atmospheric inertial motion is destroyed, the flow deviates from the inertial track in an intensified cyclonic curvature, and then turns northward toward the warm pool in the northern BOB. It therefore converges with the easterly flow on the south side of the anticyclone over the northern BOB, forming a cyclonic circulation center east of Sri Lanka. Co-located with the cyclonic circulation is a generation of atmospheric potential energy, due to lower tropospheric heating by the warm ocean. Eventually the BOB monsoon onset vortex (MOV) is generated east of Sri Lanka. As the MOV migrates northward to the warm pool it develops quickly such that the zonal oriented subtropical high is split over the eastern BOB. Thus, the tropical southwesterly on the southern and eastern sides of the MOV merges into the subtropical westerly in the north, leading to active convection over the eastern BOB and western Indochina Peninsula and onset of the Asian summer monsoon. | WU GuoXiong GUAN Yue WANG TongMei LIU YiMin YAN JingHui MAO JiangYu | 2011 | Science China Earth Sciences2011，54，1： | 16 |
