| 2 | Quantifying Responses of Winter Wheat Physiological Processes to Soil Water Stress for Use in Growth Simulation Modeling显示文摘A deep understanding of crop-water eco-physiological relations is the basis for quantifying plant physiological responses to soil water stress. Pot experiments were conducted to investigate the winter wheat crop-water relations under both drought and waterlogging conditions in two sequential growing seasons from 2000 to 2002, and then the data were used to develop and validate models simulating the responses of winter wheat growth to drought and waterlogging stress. The experiment consisted of four treatments, waterlogging (keep 1 to 2 cm water layer depth above soil surface), control (70%-80% field capacity), light drought (40%-50% field capacity) and severe drought (30%-40% field capacity) with six replicates at five stages in the 2000-2001 growth season. Three soil water content treatments (waterlogging, control and drought) with two replicates were designed in the 2001-2002 growth season. Waterlogging and control treatments are the same as in the 2000-2001 growth season. For the drought treatment, no water was supplied and the soil moisture decreased from field capacity to wilting point. Leaf net photosynthetic rate, transpiration rate, predawn leaf water potential, soil water potential, soil water content and dry matter weight of individual organs were measured. Based on crop-water eco-physiological relations, drought and waterlogging stress factors for winter wheat growth simulation model were put forward. Drought stress factors integrated soil water availability, the sensitivity of different development stages and the difference between physiological processes (such as photosynthesis, transpiration and partitioning). The quantification of waterlogging stress factor considered different crop species, soil water status, waterlogging days and sensitivity at different growth stages. Data sets from the pot experiments revealed favorable performance reliability for the simulation sub-models with the drought and waterlogging stress factors. | HUJi-Chao CAOWei-Xing ZHANGJia-Bao JIANGDong FENGJie | 2004 | Pedosphere2004，14，4： | 42 |
| 3 | Alcoholic liver disease:Utility of animal models显示文摘Alcoholic liver disease(ALD) is a major cause of acute and chronic liver injury. Extensive evidence has been accumulated on the pathological process of ALD during the past decades. However, effective treatment options for ALD are very limited due to the lack of suitable in vivo models that recapitulate the full spectrum of ALD. Experimental animal models of ALD, particularly rodents, have been used extensively to mimic human ALD. An ideal animal model should recapitulate all aspects of the ALD process, including significant steatosis, hepatic neutrophil infiltration, and liver injury. A better strategy against ALD depends on clear diagnostic biomarkers, accurate predictor(s) of its progression and new therapeutic approaches to modulate stop or even reverse the disease. Numerous models employing rodent animals have been established in the last decades to investigate the effects of acute and chronic alcohol exposure on the initiation and progression of ALD. Although significant progress has been made in gaining better knowledge on the mechanisms and pathology of ALD, many features of ALD are unknown, and require further investigation, ideally with improved animal models that more effectively mimic human ALD. Although differences in the degree and stages of alcoholic liver injury inevitably exist between animal models and human ALD, the acquisition and translational relevance will be greatly enhanced with the development of new and improved animal models of ALD. | Arantza Lamas-Paz Fengjie Hao Leonard J Nelson Maria Teresa Vázquez Santiago Canals Manuel Gómez del Moral Eduardo Martínez-Naves Yulia A Nevzorova Francisco Javier Cubero | 2018 | World Journal of Gastroenterology2018，24，45： | 26 |

| 5 | Molecular Epidemiological Analysis of Echovirus 19 Isolated From an Outbreak Associated With Hand, Foot, and Mouth Disease (HFMD) in Shandong Province of China显示文摘Objective To elucidate the genetic characterization and molecular epidemiological features of Echovirus 19(E19)isolates collected from an outbreak associated with hand,foot and mouth disease(HFMD)in Tai'an city of Shandong Province of China from July to September,2003.Methods Thirty seven Echovirus 19 isolates were isolated from stool specimens and throat swabs collected during the outbreak,then major capsid(VP1)genomic sequence was determined,and phylogenetic tree was done based on the VP1 sequences among these 37 and other E19 viruses deposited in the Genbank.Also a representative strain named CHN-SD03-TN12 was selected for sequencing of 5'-untranslated regions(5'-UTR).Results The identity rate was about 98.9%-100% among all these 37 E19 viruses.The genetic relationships between these 37 E19 isolates and other strains reported were also depicted.The identity rate was about 78.4%-78.9% compared with E19 reference strain Burke.The substitutions in the sequence of 5'-UTR resulted in changes in the conjectural properties of 5'-UTR of E19 viruses.Conclusion The genetic features of E19 viruses isolated during the outbreak in Shandong Province in 2003 may be associated with a genetic and antigenic drift that changes the virulence of the Shandong isolates,but the molecular changes in Shandong E19 viruses contributing to their phenotype remain to be further illuminated.However,the sequences described in this paper substantiate the changes taken place in capsid VP1 and 5'UTR regions.These substitutions may contribute to their tropism and virulence,and play a significant role in pathogenesis and clinical manifestations of the disease. | ZHEN ZHU WEN-BO XU AI-QIANG XU HAI-YAN WANG YONG ZHANG LI-ZHI SONG Hui-LiYANG YANLI FENGJI | 2007 | Biomedical and Environmental Sciences2007，20，4： | 22 |
| 6 | 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 |
| 7 | Relationship between matrix metalloproteinase-2 mRNA expression and clinicopathological and urokinase-type plasminogen activator system parameters and prognosis in human gastric cancer显示文摘AIM: To investigate the relationship between matrix metalloproteinase-2 (MMP-2) mRNA expression and clinicopathologic and urokinase-type plasminogen activator (uPA) system parameter and prognosis in human gastric cancer.METHODS: Expression of MMP-2 mRNA, uPA, and uPA-R mRNA in tumor tissues and ≥5 cm adjacent normal tissues from 67 cases of gastric cancer was studied using RTPCR and Northern blot respectively. Survival analyses were done using the Kaplan-Meier method. RESULTS: The expression rates of MMP-2 mRNA, uPA and uPA-R mRNA in tumor tissues (31%, 41%, and 51%, respectively) were significantly higher than those in ≥5 cm adjacent tissues (19%, 11%, and 9%; χ2 = 4.59, 43.58, and 53.24 respectively, P<0.05, 0.0001, and 0.0001, respectively). Expression of MMP-2 mRNA was significantly correlated with lymph node metastasis (metastasis:61.9%, no metastasis: 39.1%, χ2= 7.61, P<0.05), Lauren's classification of diffuse/mixed types: 54.2%, intestinal type: 26.3%, χ2 = 4.25, P<0.05, expression of uPA and uPA-R mRNA (uPA+: 55.1%, uPA-: 22.2% and uPA-R+: 54.9%, uPA-R-: 18.8%, x2= 5.72 and 6.40 respectively, P<0.05). Kaplan-Meier survival analysis of MMP-2 mRNA expression did not show significant difference in all 67 cases, but revealed an association of the expression of MMP-2 mRNA, uPA, and uPA-R mRNA with worse prognosis (P = 0.0083, 0.0160, and 0.0094, respectively). CONCLUSION: MMP-2 may play an important role in the development of invasion and metastasis of gastric cancer. | FengJi Yue-LiangChen En-YunJin Wei-LinWang Zi-LiYang You-MingLi | 2005 | World Journal of Gastroenterology2005，11，21： | 12 |
| 8 | Correlation between lower gastrointestinal tract symptoms and quality of life in patients with stable chronic obstructive pulmonary disease显示文摘OBJECTIVE:To explore correlations between the symptoms of constipation and abdominal distention and severity of chronic obstructive pulmonary disease(COPD)in patients with stable disease.METHODS:We studied 191 patients with stable COPD(according to defined criteria)in this cross-sectional study from four three-level class A Chinese medicine hospitals in China.We built an Epidata 3.0 database and performed statistical analysis with SPSS,version 17.0.We analyzed correlations between the frequency of lower gastrointestinal tract symptoms(constipation and abdominal distention)and scores for major pulmonary symptoms(cough,sputum and wheezing)based on the St.George's Respiratory Questionnaire(SGRQ),6-minute walking distance(6MWD)and frequency of acute exacerbations of COPD(AECOPD).RESULTS:In addition to their pulmonary symptoms,39.79%and 40.31%of study patients withstable COPD reported constipation and abdominal distention,respectively.Scores for major pulmonary symptoms(cough,sputum and wheezing),AECOPD and SGRQ values in patients with constipation and abdominal distention were significantly greater,and the 6MWD markedly shorter,than in those without them.According to Pearson's correlation analysis,there were strong correlations between these lower gastrointestinal tract symptoms and scores for pulmonary symptoms,SGRQ,6MWD and AECOPD.CONCLUSION:Lower gastrointestinal tract symptoms such as constipation and abdominal distention can adversely affect pulmonary symptoms,frequency of acute exacerbations and quality of life in patients with stable COPD. | Yan Sun Fengjie Zheng Yuhang Li Ruohan Wu Yuchao Liu Miao Liu Jinchao Zhang Kuo Gao | 2013 | Journal of Traditional Chinese Medicine2013，33，5： | 10 |

| 10 | A low-carbon oriented probabilistic approach for transmission expansion planning显示文摘Following the deregulation of the power industry,transmission expansion planning(TEP)has become more complicated due to the presence of uncertainties and conflicting objectives in a market environment.Also,the growing concern on global warming highlights the importance of considering carbon pricing policies during TEP.In this paper,a probabilistic TEP approach is proposed with the integration of a chance constrained load curtailment index.The formulated dynamic programming problem is solved by a hybrid solution algorithm in an iterative process.The performance of our approach is demonstrated by case studies on a modified IEEE 14-bus system.Simulation results prove that our approach can provide network planners with comprehensive information regarding effects of uncertainties on TEP schemes,allowing them to adjust planning strategies based on their risk aversion levels or financial constraints. | Jing QIU Zhaoyang DONG Junhua ZHAO Ke MENG Fengji LUO Kit Po WONG Chao LU | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，1： | 8 |
| 11 | Effect of yellow rice wine on anti-aging ability in aged mice induced by D-galactose显示文摘The present study is focused on investigation of the health protective effect of yellow rice wine(YRW)in mice and the potential underlying mechanism.Symptoms of aging were induced in mice by using Dgalactose(D-gal),and different doses of YRW(4,8,and 12 mL/kg BW)were orally administrated to D-galtreated mice for a period of six weeks.The in vivo data obtained in the present study preliminary indicated that YRW markedly increased the activity of antioxidant enzymes and reduced the concentration of MDA both in the brain and liver.Furthermore,a forced swim test showed that moderate intake of YRW(8 mL/kg BW)significantly decreased the duration of immobility,reduced the blood content of urea nitrogen and lactic acid,and increased hepatic glycogen storage.Besides,results from the Morris water maze test suggested that YRW significantly reversed cognitive impairment and also alleviated neuroapoptosis in the experimental mice by regulating the gene expressions of Bax/Bcl-2 and caspase-3.The above results indicated YRW has a potential anti-aging effect in mice and provided us certain molecular evidence for this action. | Rong Liu Zukang Fu Fengjie Zhang Qingzhong Mao Chunguang Luan Xinglin Han Jie Xue Deliang Wang Si Qin Feike Hao | 2020 | Food Science and Human Wellness2020，9，2： | 8 |
| 12 | Clinical characterization and diagnosis of cystic fibrosis throughexome sequencing in Chinese infants with Bartter-syndrome-like hypokalemia alkalosis显示文摘Cystic fibrosis (CF) is a fatal autosomal-recessive disease caused by mutations in the CFtransmembrane conductance regulator (CFTR) gene. CF is characterized by recurrent pulmonary infectionwith obstructive pulmonary disease. CF is common in the Caucasian population but is rare in the Chinesepopulation. The symptoms of early-stage CF are often untypical and may sometimes manifest as Bartter syndrome(BS)-like hypokalemic alkalosis. Therefore, the ability of doctors to differentiate CF from BS-like hypokalemicalkalosis in Chinese infants is a great challenge in the timely and accurate diagnosis of CF. In China, sporadic CFhas not been diagnosed in children younger than three years of age to date. Three infants, who were initiallyadmitted to our hospital over the period of June 2013 to September 2014 with BS-like hypokalemic alkalosis, werediagnosed with CF through exome sequencing and sweat chloride measurement. The compound heterozygousmutations of the CFTR gene were detected in two infants, and a homozygous missense mutation was found in oneinfant. Among the six identified mutations, two are novel point mutations (c.1526G 〉 C and c.3062C 〉 T) that arepossibly pathogenic. The three infants are the youngest Chinese patients to have been diagnosed with sporadic CFat a very early stage. Follow-up examination showed that all of the cases remained symptom-free after earlyintervention, indicating the potential benefit of very early diagnosis and timely intervention in children with CF.Our results demonstrate the necessity of distinguishing CF from BS in Chinese infants with hypokalemic alkalosisand the significant diagnostic value of powerful exome sequencing for rare genetic diseases. Furthermore, ourfindings expand the CFTR mutation spectrum associated with CF. | Liru Qiu Fengjie Yang Yonghua He Huiqing Yuan Jianhua Zhou | 2018 | Frontiers of Medicine2018，12，5： | 7 |
| 13 | Epidermal growth factor improves intestinal morphology by stimulating proliferation and differentiation of enterocytes and mTOR signaling pathway in weaning piglets显示文摘Epidermal growth factor(EGF) has been shown to improve piglet intestinal morphology and epithelial recovery. In an attempt to further understand the mechanisms behind these improvements, this study tested the hypothesis that dietary EGF may affect intestinal morphology by stimulating the proliferation and differentiation of enterocytes in weaning piglets. In piglets receiving200 μg kg^-1 EGF, crypt depth and villus height increased(P<0.05). Adding 400 μg kg^-1 EGF increased villus height-to-crypt depth ratio(P<0.05), but reduced crypt depth(P<0.05). Dietary supplementation with 200 μg kg^-1 EGF significantly increased the number of Ki67-positive cells(P<0.01) and tended to increase the mRNA level of proliferating cell nuclear antigen(P<0.10).However, this supplementation decreased the expression level of intestinal fatty acid-binding protein(P<0.05). Piglets fed with400 μg kg^-1 EGF had an increased mRNA level of intestinal alkaline phosphatase(P<0.05). The phosphorylation of m TOR(mammalian target of rapamycin) was observed in the 200 μg kg^-1 EGF group. These results suggest that dietary supplementation with a low level of EGF improved piglet intestinal morphology through stimulating the proliferation and differentiation of enterocytes, and the mTOR signaling pathway may partly be involved in this process. | Lixia Wang Fan Zhu Huansheng Yang Jianzhong Li Yali Li Xueqin Ding Xia Xiong Fengjie Ji Hanlin Zhou Yulong Yin | 2020 | Science China(Life Sciences)2020，63，2： | 7 |

| 15 | Geochemical characteristics of Callovian-Oxfordian carbonates in Samandepe gas field,Amu Darya Basin,Turkmenistan显示文摘The Callovian-Oxfordian carbonate reservoirs are the most important hydrocarbon reservoir in the Samandepe gas field,Amu Darya basin,Turkmenistan.Based on the analysis of Fe,Mn and Sr trace elements,and carbon,oxygen and strontium isotopes,the genesis and evolutionary characteristics of the carbonate reservoirs were studied,and the conclusions were follows:1) Sustained transgressive-regressive cycles played an important role during Callovian-Oxfordian.The reservoir of reef-bank facies was well developed in the period of transgression,while the regional dense cap rocks developed in the period of regression;2) The 87 Sr/86 Sr ratio measured from rudist shells yields an age of 157.2 Ma according to the global strontium isotope curve;3) As diagenetic intensity increased,δ 13 C changed little,and δ 18 O showed strong negative deviation but was still limited to the range of Late Jurassic seawater.High Fe and Sr contents,and low Mn content,and the evolutionary trend of δ 13 C and δ 18 O all indicate that diagenesis occurred in a relatively confined environment,where the fluids were relatively reducing and contained hot brine.The stage of diagenesis reached is mesodiagenesis,which is very favorable for preservation of primary pores in carbonates;4) Strong dissolution of reef limestones,burial dolomitization and hydrothermal calcite precipitation were all the results of the interaction between the 87 Sr-rich diagenetic fluid and rocks;5) The analysis results of isotopes,fluid inclusions and vitrinite reflectance show that the diagenetic fluid was compaction-released water that originated from the deep,coal-bearing clastic strata. | Zheng Rongcai Li Yun Wu Lei Wu Xianzhong Li Fengjie Niu Gang | 2011 | Petroleum Science2011，8，4： | 6 |
| 16 | Miniature ultrasonic probes for diagnosis and treatment of digestive tract diseases显示文摘AIM: To investigate the clinical value of miniature ultrasonic probes (MUPs) for the diagnosis and treatment of digestive tract diseases.METHODS: Endoscopic ultrasonography (EUS) was performed for patients with its indications with 7.5-20 MHz MUPs and double-cavity electronic endoscope. According to the diagnosis of MUPs, patients who had indications of treatment received endoscopic resection or surgical excision.Postoperative histological results were compared with the preoperative diagnosis of MUPs. A few patients without endoscopic resection or surgical excision were periodically followed up with MUPs.RESULTS: A total of 537 patients were examined by MUPs, of them, 256 were diagnosed with gastrointestinal submucosal lesions, 146 with pseudo-submucosal lesions,50 with digestive tract cancers, 17 with peptic ulcer, 11 with cholecystolithiasis, 8 with chronic pancreatitis, and 2 with achalasia and 47 were diagnosed as normal. After MUPs examinations, 220 patients received endoscopic resection or surgical excision, and the postoperative histological results of 211 patients were completely consistent with the preoperative diagnosis of MUPs. The diagnostic accuracy of MUPs was 95.9%. The result of follow-up with MUPs indicated that gastrointestinal leiomyoma, lipoma,phlebangioma and cyst were unchanged within 1-2 years.The patients who received endoscopic resection or centesis did not have any complications.CONCLUSION: MUPs are of value in diagnosing gastrointestinal submucosal lesions, staging of digestive tract cancers and biliary-pancreatic diseases. They play a very important role in making therapeutic plans. | Guo-QiangXu Yong-WeiLi Yong-MeiHan You-MingLi Wei-XingChen FengJi Jing-HuaLi QingGu | 2004 | World Journal of Gastroenterology2004，10，13： | 5 |
| 17 | Development and validation of an analytical method for detecting chlorantraniliprole residues in fresh tea leaves显示文摘An efficient method using multiwalled carbon nanotubes(MWCNTs)as dispersive solid-phase extraction sorbent was established for determining chlorantraniliprole residues in fresh tea leaves,which are known to be a troublesome matrix containing abundant pigments,via gas chromatography with an electron capture detector.Acetonitrile was used as the extraction solvent,with sodium chloride enhancing the analyte partition in the organic phase.The optimal mixture of MWCNTs and primary secondary amine(PSA)was based on the distribution of the target analyte recovery and on the clean-up efficiency;while matrix-matched calibration was recommended to combat the matrix effect.Mean recoveries of 95.2%–108.8%were obtained with intraday and interday precisions of less than 7.9%and 10.3%,respectively.Good linearity was observed for concentrations of 0.02–1.0 mg/kg with a correlation coefficient of 0.9984.The limits of detection and quantification were 0.005 mg/kg and 0.02 mg/kg,respectively.The method was employed to investigate the dissipation dynamics of chlorantraniliprole in fresh tea leaves with real field samples.Consequently,the dissipation rates of chlorantraniliprole in fresh tea leaves followed pseudo-first-order kinetics with a half-life of 1.9 d,and the average chlorantraniliprole residue content was below 0.02 mg/kg with a harvest withholding period of 14 d. | Tengfei Liu Minghui Dong Fengjie Zhou Daifeng Yang Xueming Zhang | 2019 | Food Science and Human Wellness2019，8，4： | 5 |
| 18 | External use of Ruyanneixiao cream efficiently blocks precancerous mammary lesions by interfering with glycolysis induced by inhibition of hypoxia inducible factor-1α, hexokinase 2, phosphofructokinase, and pyruvate kinase M2 expression显示文摘OBJECTIVE:To investigate the effect of Ruyanneixiao cream(RYNX) on the expression of hypoxia inducible factor-1α(HIF-1α), hexokinase 2(HK2),phosphofructokinase(PFK), and pyruvate kinase M2(PKM2) mRNA and protein in MCF-10 AT cells and in an animal model of precancerous mammary lesions.METHODS:Following treatment of MCF-10 AT cells with RYNX, tamoxifen(TAM) and YC-1 for 48 h,HIF-1α, HK2, PFK, PKM2 mRNA and protein expression was analyzed.Fifty female SD rats were randomly divided into control, model, TAM, and highand low-dose RYNX groups, with 10 rats in each group.A precancerous mammary lesion model was established for all groups except the control group.High-and low-dose RYNX cream containing TAM was coated on the breasts of animals in the corresponding groups.The rat mammary tissue was removed in the 10 th week and HIF-1α, HK2, PFK,PKM2 mRNA and protein was analyzed.RESULTS:In vitro analyses demonstrated that, compared with the matrix group, HIF-1α, HK2, PFK,PKM2 mRNA and protein expression was significantly decreased in the RYNX group(P < 0.05).Compared with the YC-1 + RYNX group, HK2, PFK,and PKM2 protein expression was significantly reduced in the RYNX group.HIF-1α, HK2, PFK, and PKM2 protein expression was increased significantly in the model group(P < 0.05) compared with the control group, while HIF-1α, HK2, PFK, and PKM2 mRNA and protein expression was significantly decreased in both the high-and low-dose RYNX groups(P < 0.05), with the effect being greater in the high-dose group.CONCLUSION:RYNX can block precancerous breast lesions by decreasing the expression of HK2,PFK, and PKM2 mRNA and protein via inhibition of HIF-1α mRNA and protein overexpression in a dose-dependent manner. | Li Xiaobo Ma Min Zhang Guijuan Ma Yi Liao Rui Chen Ruixue Yan Xianxin Bie Fengjie Huang Maojie Liang Shijie | 2017 | Journal of Traditional Chinese Medicine2017，37，2： | 5 |
