| 1 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014,57,1: | 106 |

| 4 | 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 |

| 6 | Neural mechanism of acupuncture-modulated gastric motility显示文摘AIM: To investigate the acupuncture-modulated gastric motility and its underlying neural mechanism.METHODS: Intragastric pressure and/or waves of gastric contraction in rats were recorded by intrapyloric balloon and changes of gastric motility induced by acupuncture stimulation were compared with the background activity before any stimulation. Gastro-vagal or splanchnic-sympathetic nerves were recorded or cut respectively for investigating the involvement of autonomic nerve pathways. Spinalization experiment was also performed.RESULTS: Acupuncture-stimulation by exciting Aδ and/or C afferent fibers, could only modulate gastric motility. Acupuncture-stimulation on fore- and hind-limbs evoked a moderate gastric motility followed by increased vagus discharges with unchanged sympathetic activity, while the same stimulus to the acupoints in abdomen resulted in reversed effects on gastric motility and autonomic nervous activities. The inhibitory gastric response was completely abolished by splanchnic denervation, but the facilitative gastric response to stimulation of acupoints in limbs was not influenced, which was opposite to the effect when vagotomy was performed. The similar depressive effects were produced by the stimulation at the acupoints homo-segmental to the gastric innervation in the animals with or without spinalization. However, the facilitation induced by the stimulation at the acupoints hetero-segmental to the gastric innervation was not observed in the spinalized animals.CONCLUSION: Facilitative effects of stimulating hetero-segmental acupoints are involved in the intact preparation of vagal nerves and spinal cord, while the inhibitory response induced by stimulating homo-segmental acupoints is involved in the intact preparation of sympathetic nerves. Only the acupuncture-stimulation with intensity over the threshold of Aδ and/or C afferent fibers can markedly modulate gastrointestinal motility. | Yu-Qing Li Bing Zhu Pei-Jing Rong Hui Ben Yan-Hua Li | 2007 | World Journal of Gastroenterology2007,13,5: | 41 |

| 8 | Does Helicobacter pylori infection play a role in iron deficiency anemia? A meta-analysis显示文摘AIM:To perform a meta-analysis of observational studies and randomized controlled trials(RCTs)on the association between Helicobacter pylori(H.pylori)and iron deficiency anemia(IDA).METHODS:A defined search strategy was used to search Medline,Embase,the Cochrane Library,Clinical Trials,Cochrane Central Register of Controlled Trials,Premedline and Healthstar.Odds ratio(OR)was used to evaluate observational epidemiology studies,and weighted mean difference(WMD)was used to demonstrate the difference between control and intervention groups.RESULTS:Fifteen observational studies and 5 RCTs were identified and used for calculation.The pooled OR for observational studies was 2.22(95%CI:1.52-3.24,P<0.0001).The WMD for hemoglobin(HB) was 4.06 g/L(95%CI:-2.57-10.69,P=0.01),and the WMD for serum ferritin(SF)was 9.47μg/L(95%CI:-0.50-19.43,P<0.0001).Results were heterogeneous for all comparisons.CONCLUSION:This meta-analysis on observational studies suggests an association between H.pylori and IDA.In RCTs,eradication of H.pylori can improve HB and SF levels but not significantly. | Qu, Xin-Hua Huang, Xiao-Lu Xiong, Ping Zhu, Cui-Ying Huang, You-Liang Lu, Lun-Gen Sun, Xu Rong, Lan Zhong, Liang Sun, Da-Yu Lin, Hai Cai, Ming-Ci Chen, Zhi-Wei Hu, Bing Wu, Lian-Ming Jiang, Yi-Bin Yan, Wei-Li | 2010 | World Journal of Gastroenterology2010,16,7: | 34 |
| 9 | Temperature variations in the past 6000 years inferred from δ^(18)O of peat cellulose from Hongyuan,China显示文摘Trends of the temperature variations recorded in δ18O in Hongyuan peat cellulose are similar to those recorded in δ18O of Jinchuan peat cellulose and in δ18O of Dunde ice core. Climate events have been identified to be globally homogeneous. Two notable climate transition periods have been detected in the past 6000 years, namely 4000 aBP with climate shifting from cold to warm and 1500 aBP with climate shifting from warm to relatively cold. Power spectrum analysis was performed to investigate the periodical signals in the δ18O time series. Typical periodicities of 1200-1087 a, 752 a, 444 a, 325 a, 213 a, 127-123 a, 88 a, 79 a were discovered, indicating an integrated influence on Hongyuan climate from solar, monsoon and ocean activities. Solar forcing has been addressed to be the main driving forcing of Hongyuan climate. | XU Hai, HONG Yetang, LIN Qinghua, HONG Bing, JIANG Hongbo & ZHU YongxuanInstitute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China Graduate School of Chinese Academy of Sciences, Beijing 100039, China | 2002 | Chinese Science Bulletin2002,47,18: | 31 |
| 10 | The spectrum-effect relationship——a rational approach to screening effective compounds, reflecting the internal quality of Chinese herbal medicine显示文摘Since the chromatographic fingerprint was introduced, it has been accepted by many countries to assess the quality and authenticity of Chinese herbal medicine(CHM). However, solely using the chromatographic fingerprint to assay numerous chemicals is not suitable for the assessment of the whole internal quality and pharmacodynamics of CHM. Consequently, it is necessary to develop a rational approach to connecting the chromatographic fingerprint with effective components to assess the internal quality of CHM. For this purpose, a spectrum-effect relationship theory was proposed and accepted as a new method for the assessment of CHM because of its potential use to screen effective components from CHM. In this paper, we systematically reviewed the application of the spectrum-effect relationship theory in the research of CHM, including research mentality, different chromatographic analysis techniques, data processing technologies, and structure determination. | ZHU Chun-Sheng LIN Zhi-Jian XIAO Ming-Liang NIU Hong-Juan ZHANG Bing | 2016 | Chinese Journal of Natural Medicines2016,14,3: | 29 |

| 12 | Effective regularity in modulation on gastric motility induced by different acupoint stimulation显示文摘AIM: To investigate whether manual acupuncture at representative acupoints in different parts of the body can modulate responses of gastric motility in rats and regular effects in different acupoint stimulation.METHODS: The gastric motor activity of rats was recorded by the intrapyloric balloon. The changes of gastric motility induced by the stimulation were compared with the background activity in intragastric pressure and/or waves of gastric contraction recorded before any stimulation. Morphological study was also conducted by observing the Evans dye extravasation in the skin after mustard oil injection into the intragastric mucous membrane to certify cutaneous innervations of blue dots related to gastric segmental innervations. RESULTS: In all six rats that received mustard oil injections into intragastric mucosa, small blue dots appeared in the skin over the whole abdomen, but mainly in peri-midline upper- and middle- abdomen and middle-back, a few in thigh and groin. It may speculate that cutaneous innervations of blue dots have the same distribution as gastric segmental innervations. Acu-stimulation in acupoints of head-neck, four limbs, upper chest-dorsum and lower-dorsum induced markedly augmentation of gastric motility (acupoints on head-neck such as St-2: n = 16, 105.19 ± 1.36 vs 112.25 ± 2.02 and St-3: n = 14, 101.5 ± 1.75 vs 109.36 ± 1.8; acupoints on limbs such as Sp-6: n = 19, 100.74 ± 1.54 vs 110.26 ± 3.88; St-32: n = 17, 103.59 ± 1.64 vs 108.24 ± 2.41; St-36: n = 16, 104.81 ± 1.72 vs 110.81 ± 2.74 and Li-11: n = 17, 106.47 ± 2.61 vs 114.77 ±3.77, P < 0.05-0.001). Vigorous inhibitory regulations of gastric motility induced by acu-stimulation applied in acupoints on whole abdomen and middle-dorsum were significantly different as compared with the controls before acu-stimulation (abdomen acupoints such as Cv-12: n = 11, 109.36 ± 2.09 vs 101 ± 2.21; Cv-6: n = 18, 104.39 ± 1.42 vs 91.83 ± 3.22 and St-21: n = 12, 107 ± 2.97 vs 98.58 ± 2.81; acupoints on middle-dorsum such as Bl-17: n = 19, 100.63 ± 1.4 vs 92.21 ± 2.07 and Bl-21: n = 19, 103.84 ± 1.48 vs 97.58 ± 2.16, P < 0.05-0.001).CONCLUSION: Regular regulatory effects of facilitation and inhibition on gastric motility appear to be somatotopically organized in the acupoints of whole body, and the effective regularity of site-special acupoints on gastric motility is involved in segmental innervations between stomach and acupoints. | Yu-Qing Li Bing Zhu Pei-Jing Rong Hui Ben Yan-Hua Li | 2006 | World Journal of Gastroenterology2006,12,47: | 25 |
| 13 | Effect of dietary supplementation with mulberry(Morus alba L.) leaves on the growth performance,meat quality and antioxidative capacity of finishing pigs显示文摘The present study was conducted to evaluate the effect of dietary mulberry(Morus alba L.) leaves powder(MLP) supplementation on meat quality of finishing pigs.A total of 40 Duroc×Landrace×Yorkshire pigs(initial body weight of(40.5±0.63) kg) were randomly allotted into two treatments,fed either with control diet or 15% MLP diet for 85 d.The results showed that MLP diet decreased(P≤0.05) average daily gain(ADG) and increased(P<0.05) feed/gain ratio(F/G) in the finishing and whole period.MLP diet also decreased(P<0.05) carcass weight,dressing percentage,last rib and average backfat depth.However,MLP diet increased(P<0.05) intramuscular fat(IMF) content,decreased(P<0.05) shear force,cooking loss and drip loss.In addition,MLP diet increased(P<0.05) total antioxidative capacity,glutathione peroxidase and tended(P<0.10) to increase total superoxide dismutase in serum.In longissimus thoracis,myosin heavy chain(MyHC) I and IIa mRNA levels were increased(P≤0.05) for MLP diet.In conclusion,15% MLP supplementation reduced the growth performance and carcass traits,but improved meat quality of finishing pigs possibly through the change of myofiber characteristics,enhancement of antioxidative capacity and increase of IMF. | ZENG Zhu JIANG Jun-jie YU Jie MAO Xiang-bing YU Bing CHEN Dai-wen | 2019 | Journal of Integrative Agriculture2019,18,1: | 24 |
| 14 | Nedaplatin concurrent with three-dimensional conformal radiotherapy for treatment of locally advanced esophageal carcinoma显示文摘AIM:To evaluate the efficacy and toxicity of nedaplatin(NDP)concurrent with radiotherapy in the treatment of locally advanced esophageal carcinoma.METHODS:Sixty-eight patients with locally advanced esophageal carcinoma were randomized into either a NDP group(n=34)or a cisplatin(DDP)group(n=34).The NDP group received NDP 80-100 mg/m2iv on day 1+leucovorin(CF)100 mg/m2iv on days 1-5+5-fluorouracil(5-FU)500 mg/m2iv on days 1-5.The DDP group received DDP 30 mg/m2iv on days 1-3+CF 100 mg/m2on days 1-5+5-FU 500 mg/m2iv on days 1-5.The treatment was repeated every 4 wk in both groups.Concurrent radiotherapy[60-66 Gy/(30-33f)/(6-7 wk)]was given during chemotherapy.RESULTS:There was no significant difference in the short-term response rate between the NDP group and DDP group(90.9%vs 81.3%,P=0.528).Although the 1-and 2-year survival rates were higher in the NDP group than in the DDP group(75.8%vs 68.8%,57.6%vs 50.0%),the difference in the overall survival rate was not statistically significant between the two groups(P=0.540).The incidences of nausea,vomiting and nephrotoxicity were significantly lower in the NDP group than in the DDP group(17.6%vs 50.0%,P=0.031;11.8%vs 47.1%,P=0.016;8.8%vs 38.2%,P=0.039).There was no significant difference in the incidence of myelosuppression,radiation-induced esophagitis or radiation-induced pneumonia between the two groups.CONCLUSION:NDP-based concurrent chemoradiotherapy is effective and well-tolerated in patients with locally advanced esophageal carcinoma.NDP-based regimen has comparable efficacy to DDP-based regimen but is associated with lower incidences of gastrointestinal and renal toxicity. | Ze-Tian Shen Xin-Hu Wu Bing Li Jun-Shu Shen Zhen Wang Jing Li Xi-Xu Zhu | 2013 | World Journal of Gastroenterology2013,19,48: | 23 |
| 15 | A 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 | 2020 | Molecular Plant2020,13,6: | 23 |
| 16 | Changes of protein oxidation,lipid oxidation and lipolysis in Chinese dry sausage with different sodium chloride curing salt content显示文摘The effect of sodium chloride(NaCl)curing salt content on protein oxidation,lipid oxidation and lipolysis of Chinese dry sausage was investigated.Two groups Chinese dry sausages with 2%and 4%(m/m)salt content were studied.The degree of protein oxidation increased during the processes in two groups sausages,while the content of phospholipids decreased,neutral lipids and free fatty acids increased.The degree of protein oxidation,lipid oxidation and lipolysis in 4%NaCl content group was higher than those in 2%NaCl content group,while 4%NaCl content group has higher lipase activity.In conclusion,4%NaCl may facilitate the protein oxidation,lipid hydrolysis and oxidation in Chinese dry sausage,and the protein oxidation had strong correlation with lipid oxidation and lipolysis.The results could provide a basis for improving the technology of industrial production. | Bing Zhao Huimin Zhou Shunliang Zhang Xiaoqian Pan Su Li Ning Zhu Qianrong Wu Shouwei Wang Xiaoling Qiao Wenhua Chen | 2020 | Food Science and Human Wellness2020,9,4: | 22 |
| 17 | In vitro differentiation of adipose-derived stem cells and bone marrow-derived stromal stem cells into neuronal-like cells显示文摘Adipose-derived stem cells and bone marrow-derived stromal stem cells were co-cultured with untreated or Aβ1-40-treated PC12 cells, or grown in supernatant derived from untreated or Aβ1-40-treated PC12 cells. Analysis by western blot and quantitative real-time PCR showed that protein levels of Nanog, Oct4, and Sox2, and mRNA levels of miR/125a/3p were decreased, while expression of insulin-like growth factor-2 and neuron specific enolase was increased. In comparison, the generation of neuron specific enolase-positive cells was most successful when adipose-derived stem cells were co-cultured with Aβ1-40-treated PC12 cells. Our results demonstrate that adipose-derived stem cells and bone marrow-derived stromal stem cells exhibit trends of neuronal-like cell differentiation after co-culture with Aβ1-40-treated PC12 cells. This process may relate to a downregulation of miR-125a-3p mRNA expression and increased levels of insulin-like growth factor-2 expression. | Jin Zhou Guoping Tian Jing'e Wang Xuefeng Cong Xingkai Wu Siyang Zhang Li Li Bing Xu Feng Zhu Xuedan Luo Jian Han Fengjie Hu | 2011 | Neural Regeneration Research2011,6,19: | 21 |
