| 2 | 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 |
| 3 | Effect of subsoil tillage depth on nutrient accumulation, root distribution, and grain yield in spring maize显示文摘A four-year field experiment was conducted to investigate the effect of subsoiling depth on root morphology, nitrogen(N), phosphorus(P), and potassium(K) uptake, and grain yield of spring maize. The results indicated that subsoil tillage promoted root development,increased nutrient accumulation, and increased yield. Compared with conventional soil management(CK), root length, root surface area, and root dry weight at 0–80 cm soil depth under subsoil tillage to 30 cm(T1) and subsoil tillage to 50 cm(T2) were significantly increased, especially the proportions of roots in deeper soil. Root length, surface area, and dry weight differed significantly among three treatments in the order of T2 > T1 > CK at the12-leaf and early filling stages. The range of variation of root diameter in different soil layers in T2 treatment was the smallest, suggesting that roots were more likely to grow downwards with deeper subsoil tillage in soil. The accumulation of N, P, and K in subsoil tillage treatment was significantly increased, but the proportions of kernel and straw were different. In a comparison of T1 with T2, the grain accumulated more N and P, while K accumulation in kernel and straw varied in different years. Grain yield and biomass were increased by 12.8% and 14.6% on average in subsoil tillage treatments compared to conventional soil treatment. Although no significant differences between different subsoil tillage depths were observed for nutrient accumulation and grain yield, lodging resistance of plants was significantly improved in subsoil tillage to 50 cm, a characteristic that favors a high and stable yield under extreme environments. | Hongguang Cai Wei Ma Xiuzhi Zhang Jieqing Ping Xiaogong Yan Jianzhao Liu Jingchao Yuan Lichun Wang Jun Ren | 2014 | The Crop Journal2014,2,5: | 42 |
| 4 | Ultrasonography guided percutaneous radiofrequency ablation for hepatic cavernous hemangioma显示文摘AIM: Hepatic cavernous hemangioma (HCH) is the mostcommon benign tumor of the liver and its management isstill controversial. Recent successin situ radiofrequencyablation of hepatic malignancies has led us to consider usingthis technique in patients with HCH. This study was to assessthe efficacy, safety, and complications of percutaneousradiofrequency ablation (PRFA) under ultrasonographyguidance in patients with HCH.METHODS: Twelve patients (four men and eight women,age ranged 33-56 years, mean age was 41.7 years) with 15hepatic cavernous hemangiomas (2.5 cm to 9.5 cm) weretreated using the RF-2000 generator and 10-needle LeVeenelectrode percutaneously guided by B-ultrasound. Lesionslarger than 3 cm were treated by multiple overlappingablations that encompass the entire lesion as well as a rimof normal liver tissue (approximately 0.5 cm).RESULTS: All the patients who received PRFA therapy hadno severe pain, bleeding or bile leakage during and afterthe procedures. Nine to 34 months′ follow-up (mean, 21months) by ultrasound and/or spiral CT scan demonstratedthat the ablated lesions in this group were shrunk remarkably,and the shrunken range was 38-79 % (mean, 67 % per 21months). The contrast enhancement was disappeared withinthe tumor or at its periphery in all cases on spiral CT scansobtained 3 to 6 months after treatment.CONCLUSION: The results of this study suggest that PRFAtherapy is a mini-invasive, simple, safe, and effective methodfor the treatment of selected patients with HCH. | Yan Cui Li-Yan Zhou Man-Ku Dong Ping Wang Min Ji Xiao-Ou Li Chang-Wei Chen Zi-Pei Liu Yong-Jie Xu Hong-Wen Zhang Department of Hepatobiliary Surgery,Beijing 306 Hospital,Chaoyang District,Beijing 100101,China | 2003 | World Journal of Gastroenterology2003,9,9: | 43 |

According to thedirection of cell-function differentiation,stomach carcinomas were divided into fivefunctionally differentiated types.iation type (AFDT): there were 82 (22.7%)patients including 76 (92.7%) aged 45 years.Sixty-nine (84.1%) cases belonged to theintestinal type. Thirty-eight (46.3%) expressedCD44v6 and 9 (13.6%) of 66 male patientsdeveloped liver metastasis. The 5-year survivalrate of patients in this group (58.5%) was higherMucin secreting function differentiation type(MSFDT): 54 (15%) cases. Fifty-three (98.1%)tumors had penetrated the serosa, 12 (22.2%)expressed ER and 22 (40.7%) expressedCD44v6. The postoperative 5-year survival ratefunction differentiation type (AMPFDT): therewere 180 (49.9%) cases, including 31 (17.2%)aged yanger than 45 years. The tumor was morecommon in women (62, 34.4%,) and expressedmore frequently estrogen receptors (ER) ( 129,81.7%) than other types (P<0.01). Ovarymetastasis was found in 12 (19.4%) out of 62female subjects. The patients with this type GChad the lowest 5-year survival rate (24.7%)differentiation type (SFDT): 13 (3.6%) cases.Nine (69.2%) tumors of this type derived fromAPUD system, the other 4 (30.7%) were ofdifferent histological differentiation. Sixty percent of the patients survived at least five years.(8.9%) cases. Nineteen (59.4%) cases hadlymph node metastases but no one with liver orovary metastasis. The 5-year survival rate was28.1%.CONCLUSION This new cell-functionclassification of GC is helpful in indicating thecharacteristics of invasion and metastasis of GCwith different cell-function differentiationphenotypes. Further study is needed to disclosethe correlation between the cell-functionaldifferentiation phenotypes and the relevantgenotypes and the biological behavior of gastriccarcinoma. | Yan Xin Xiao Ling Li Yan Ping Wang Su Min Zhang Hua Chuan Zheng Dong Ying Wu Yin Chang Zhang The Fourth Laboratory of Cancer Institute, China Medical University, Shenyang 110001, Liaoning Province, China | 2001 | World Journal of Gastroenterology2001,7,1: | 38 |
| 6 | Recent Advances on the Technologies to Increase Fertilizer Use Efficiency显示文摘To increase fertilizer use efficiency (FUE) and to minimize its negative impact on environment have been the focal points in the world for a long time. It is very important to increase FUE in China for its relatively low FUE and serious losses of nutrients. Recent advances of the technologies to increase FUE are reviewed in this article. These include site-specific and real-time nitrogen management, non-destructive quick test of the nitrogen status of plants, new types of slow release and controlled release fertilizers, site-specific nutrient management, and use of urease inhibitor and nitrification inhibitor to decrease nitrogen losses. Future outlook in technologies related to FUE improvement is also discussed. | YAN Xiang JIN Ji-yun HE Ping LIANG Ming-zao | 2008 | Agricultural Sciences in China2008,7,4: | 35 |

| 8 | Resveratrol Induces Apoptosis and Autophagy in T-cell Acute Lymphoblastic Leukemia Cells by Inhibiting Akt/mTOR and Activating p38-MAPK显示文摘Objective To explore the effects of resveratrol-induced apoptosis and autophagy in T-cell acute lymphoblastic leukemia(T-ALL) cells and potential molecular mechanisms. Methods The anti-proliferation effect of resveratrol-induced, apoptosis and autophagy on T-ALL cells were detected by using MTT test, immunofluorescence, electronic microscope, and flow cytometry, respectively. Western blotting was performed for detecting changes of apoptosis-associated proteins, cell cycle regulatory proteins and state of activation of Akt, mTOR, p70S6K, 4E-BP1, and p38-MAPK. Results Resveratrol inhibited the proliferation and induced apoptosis and autophagy in T-ALL cells in a dose and time-dependent manner. It also induced cell cycle arrest at G0/G1 phase via up regulating cyclin-dependent kinase(CDK) inhibitors p21 and p27 and down regulating cyclin A and cyclin D1. Western blotting revealed that resveratrol significantly decreased the expression of antiapoptotic proteins(Mcl-1 and Bcl-2) and increased the expression of proapoptotic proteins(Bax, Bim, and Bad), and induced cleaved-caspase-3 in a time-dependent manner. Significant increase in ratio of LC3-II/LC3-I and Beclin 1 was also detected. Furthermore, resveratrol induced significant dephosphorylation of Akt, mTOR, p70S6K, and 4E-BP1, but enhanced specific phosphorylation of p38-MAPK which could be blocked by SB203580. When autophagy was suppressed by 3-MA, apoptosis in T-ALL cells induced by resveratrol was enhanced.Conclusion Our findings have suggested that resveratrol induces cell cycle arrest,apoptosis,and autophagy in T-ALL cells through inhibiting Akt/mTOR/p70S6K/4E-BP1 and activating p38-MAPK signaling pathways.Autophagy might play a role as a self-defense mechanism in T-ALL cells treated by resveratrol.Therefore,the reasonable inhibition of autophagy in T-ALL cells may serve as a promising strategy for resveratrol induced apoptosis and can be used as adjuvant chemotherapy for T-ALL. | GE Jiao LIU Yan LI Qiang GUO Xia GU Ling MA Zhi Gui ZHU Yi Ping | 2013 | Biomedical and Environmental Sciences2013,26,11: | 38 |

| 10 | 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 |
| 11 | Loess in the Tian Shan and its implications for the development of the Gurbantunggut Desert and drying of northern Xinjiang显示文摘Eolian loess is widely distributed on the various geomorphic surfaces between 700-2400 m a.s.l. on the northern slope of the Tian Shan. It is formed in a synchronous manner with dust transported from the Gurbantunggut Desert in the Junggar Basin. The thickest section of loess was found in the Shawan and Shihezi regions. Paleomagnetic and climatic proxy analyses of over 71 m of a loess-paleosol sequence on the highest terrace of the Qingshui He (River) in the Shawan show that the paleomagnetic Bruhues/Matuy-ama (B/M) boundary lies at the bottom of paleosol S8, at a depth of 69.5 m, and the bottom of the sequence was estimated to be -0.8 Ma. This implies that the extremely dry climatic conditions in the Junggar Basin and the initial Gurbantunggut Desert were present at least by 0.8 Ma. High-resolution grain size series demonstrate that this area and desert expansion experienced two dramatic periods of desert expansions that occurred at -0.65 Ma and 0.5 Ma, respectively; and the subsequent continuous | FANG Xiaomin SHI Zhentao YANG Shengli YAN Maodu LI Jijun JIANG Ping’an | 2002 | Chinese Science Bulletin2002,47,16: | 33 |
| 12 | The Relationship between Glucose Excursion and Cognitive Function in Aged Type 2 Diabetes Patients显示文摘Objective Evidence suggests that type 2 diabetes (T2DM) is associated with an increased risk of dementia and that glucose variability is an independent risk factor for diabetic complications.This study investigated the relationship between glucose excursion and cognitive function in aged T2DM patients.Methods A total of 248 aged T2DM patients wore a continuous glucose monitoring system (CGMS) for 3 days in order to evaluate glucose excursion,including mean amplitude of glycemic excursions (MAGE) and mean of daily difference (MODD).All subjects were evaluated with a number of accepted cognitive function tests,including themini‐mental status examination (MMSE).The relationship between MAGE and MODD and performance on these cognitive tests was assessed.Results The MAGE and MMSE score were negatively correlated,likewise with the correlation between MODD and MMSE.Liner multivariate regression analysis showed that MAGE and MODD were also negatively related to MMSE independent of age,sex,glycemic control,hypertension,smoking,or coronary heart disease history.Conclusion Glucose excursion is related to cognitive function in aged T2DM patients.Elevated glucose excursion decreased the MMSE score,which reflects general cognitive function.Thus,therapy aimed at controlling glucose excursion may be beneficial for maintaining cognitive function in aged T2DM patients. | ZHONG Yuan ZHANG Xiao Yan MIAO Ya ZHU Jie Hua YAN Hong WANG Bei Yun JIN Jun HU Ting Jun JIA Wei Ping | 2012 | Biomedical and Environmental Sciences2012,25,1: | 34 |
| 13 | 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 |

| 15 | Ethanol induced mitochondria injury and permeability transition pore opening: Role of mitochondria in alcoholic liver disease显示文摘AIM: To observe changes of mitochondria and investigate the effect of ethanol on mitochondrial perme- ability transition pore (PTP), mitochondrial membrane potential (MMP, ΔΨm) and intracellular calcium concentration in hepatocytes by establishing an animal model of alcoholic liver disease (ALD). METHODS: Fourty adult male Wistar rats were randomly divided into two groups, the model group (20) was administered alcohol intragastrically plus an Oliver oil diet to establish an ALD model, and the control group (20) was given an equal amount of normal saline. The ultramicrostructural changes of mitochondria were observed under electron microscopy. Mitochondria of liver was extracted, and patency of PTP, mitochondrial membrane potential (ΔΨm), mitochondrial mass and intracellular calcium concentration of isolated hepacytes were detected by flow cytometry using rhodamine123 (Rh123), Nonyl-Acridine Orange and calcium fluorescent probe Fluo-3/AM, respectively. RESULTS: Membrane and cristae were broken or disappeared in mitochondria in different shapes under electron microscopy. Some mitochondria showed U shape or megamitochondrion. In the model group, liver mitochondria PTP was broken, and mitochondria swelled, the absorbance at 450 nm, A540 decreased (0.0136 ± 0.0025 vs 0.0321 ± 0.0013, model vs control, P < 0.01); mitochondria transmembrane potential (239.4638 ± 12.7263 vs 377.5850 ± 16.8119, P < 0.01) was lowered; mitochondrial mass (17.4350 ± 1.9880 vs 31.6738 ± 3.4930, P < 0.01); and [Ca2+]i was increased in liver cells (7.0020 ± 0.5008 vs 10.2050 ± 0.4701, P < 0.01).CONCLUSION: Chronic alcohol intake might lead to broken mitochondria PTP, decreased mitochondria membrane potential and injury, and elevated intracellular Ca2+ production. Ethanol-induced chondriosome injury may be an important mechanism of alcoholic diseases. | Ming Yan Ping Zhu Hui-Min Liu Hai-Tao Zhang Li Liu | 2007 | World Journal of Gastroenterology2007,13,16: | 26 |
| 16 | Serum leptin and soluble leptin receptor in non-alcoholic fatty liver disease显示文摘AIM: To determine the role of leptin system in non-al- coholic fatty liver disease (NAFLD) development by deli- neating the changes in serum levels of leptin and soluble leptin receptor (sOB-R). METHODS: Blood samples were collected from 30 consecutive patients with liver-biopsy-proven NAFLD and 30 patients with cholecystolithiasis (stationary phase) as controls. Serum leptin levels were determined by radio- immunoassay and concentration of sOB-R was measured by ELISA. Body mass index (BMI) was calculated for all subjects, and serum insulin, C-peptide, and lipoprotein levels were also detected. RESULTS: Mean serum leptin level and BMI in the NAFLD group were significantly higher than in the con- trols (both P < 0.001), but mean sOB-R level was lower in the NAFLD group when compared to the controls. Both men and women in the NAFLD group had higher mean serum leptin levels and lower sOB-R levels than did the men and women in the control group (all P < 0.001). The- re was a significant negative correlation between serum leptin and sOB-R levels (r = -0.725, P < 0.001). Multiva- riate analysis showed that the percentage of hepatocyte steatosis, sex, BMI, and homeostasis model assessment of insulin resistance (HOMA IR) were independently rela- ted to serum leptin levels. CONCLUSION: Elevated serum leptin seems to be afeature of steatosis, and serum leptin seems to increase as hepatocyte steatosis develops. An enhanced release of leptin is accompanied by an decrease in sOB-R con- centration, which suggests higher resistance of periphe- ral tissues towards the action of leptin. | Xiao-Dong Huang Yan Fan Hen Zhang Ping Wang Jing Ping Yuan Ming-Jie Li Xi-Yan Zhan | 2008 | World Journal of Gastroenterology2008,14,18: | 26 |
| 17 | Screening and breeding of high taxol producing fungi by genome shuffling显示文摘To apply the fundamental principles of genome shuffling in breeding of taxol-producing fungi, Nodulisporium sylviform was used as starting strain in this work. The procedures of protoplast fusion and genome shuffling were studied. Three hereditarily stable strains with high taxol production were obtained by four cycles of genome shuffling. The qualitative and quantitative analysis of taxol produced was confirmed using thin-layer chromatography (TLC), high performance liquid chromatography (HPLC) and LC-MS. A high taxol producing fungus, Nodulisporium sylviform F4-26, was obtained, which produced 516.37 μg/L taxol. This value is 64.41% higher than that of the starting strain NCEU-1 and 31.52%―44.72% higher than that of the parent strains. | ZHAO Kai, PING WenXiang, ZHANG LiNa, LIU Jun, LIN Yan, JIN Tao & ZHOU DongPo Laboratory of Microbiology, College of Life Science, Heilongjiang University, Harbin 150080, China | 2008 | Science China(Life Sciences)2008,51,3: | 25 |
| 18 | Basic Soil Productivity of Spring Maize in Black Soil Under Long-Term Fertilization Based on DSSAT Model显示文摘Increasing basic farmland soil productivity has significance in reducing fertilizer application and maintaining high yield of crops. In this study, we defined that the basic soil productivity(BSP) is the production capacity of a farmland soil with its own physical and chemical properties for a specific crop season under local environment and field management. Based on 22-yr(1990-2011) long-term experimental data on black soil(Typic hapludoll) in Gongzhuling, Jilin Province, Northeast China, the decision support system for an agro-technology transfer(DSSAT)-CERES-Maize model was applied to simulate the yield by BSP of spring maize(Zea mays L.) to examine the effects of long-term fertilization on changes of BSP and explore the mechanisms of BSP increasing. Five treatments were examined:(1) no-fertilization control(control);(2) chemical nitrogen, phosphorus, and potassium(NPK);(3) NPK plus farmyard manure(NPKM);(4) 1.5 time of NPKM(1.5NPKM) and(5) NPK plus straw(NPKS). Results showed that after 22-yr fertilization, the yield by BSP of spring maize significantly increased 78.0, 101.2, and 69.4% under the NPKM, 1.5NPKM and NPKS, respectively, compared to the initial value(in 1992), but not significant under NPK(26.9% increase) and the control(8.9% decrease). The contribution percentage of BSP showed a significant rising trend(P<0.05) under 1.5NPKM. The average contribution percentage of BSP among fertilizations ranged from 74.4 to 84.7%, and ranked as 1.5NPKM>NPKM>NPK≈NPKS, indicating that organic manure combined with chemical fertilizers(1.5NPKM and NPKM) could more effectively increase BSP compared with the inorganic fertilizer application alone(NPK) in the black soil. This study showed that soil organic matter(SOM) was the key factor among various fertility factors that could affect BSP in the black soil, and total N, total P and/or available P also played important role in BSP increasing. Compared with the chemical fertilization, a balanced chemical plus manure or straw fertilization(NPKM or NPKS) not only increased the concentrations of soil nutrient, but also improved the soil physical properties, and structure and diversity of soil microbial population, resulting in an iincrease of BSP. We recommend that a balanced chemical plus manure or straw fertilization(NPKM or NPKS) should be the fertilization practices to enhance spring maize yield and improve BSP in the black soil of Northeast China. | ZHA Yan WU Xue-ping HE Xin-hua ZHANG Hui-min GONG Fu-fei CAI Dian-xiong ZHU Ping GAO Hong-jun | 2014 | Journal of Integrative Agriculture2014,13,3: | 25 |

| 20 | Construction, expression and characterization of the engineered antibody against tumor surface antigen, p185^(c-erbB-2)显示文摘The c-erbB-2 proto-oncogene encodes a 185kDa protein p185, which belongs to epidermal growth factorreceptor family. Amplification of this gene has been shown to correlate with poor clinical prognosis forcertain cancer patients. The monoclonal antibody A21 which directed against p185 specifically inhibitsproliferation of tumor cells overexpressing p185, hence allows it to be a candidate for targeted therapy. Inorder to overcome several drawbacks of murine MAb, we cloned its VH and VL genes and constructed thesingle-chain Fv (scFv) through a peptide linker. The recombinant scFvA21 was expressed in Escherichiacoli and purified by the affinity column. Subsequently it was characterized by ELISA, Western blot, cellimmunohistochemistry and FACS. All these assays showed the binding activity to extracellular domain(ECD) of p185. Based on those properties of scFvA21, we further constructed the scFv-Fc fusion moleculewith a homodimer form and the recombinant product was expressed in mammalian cells. In a series ofsubsequent analysis this fusion protein showed identical antigen binding site and activity with the parentantibody. These anti-p185 engineered antibodies have promised to be further modified as a tumor targetingdrugs, with a view of application in the diagnosis and treatment of human breast cancer. | LIAN SHENG CHENG, AI PING LIU, JIA HONG YANG, YAN QIU DONG, LIANG WEI LI, JING WANG, CHAO CHEN WANG, JING LIUSchool of Life Science, University of Science and Technology of China, Hefei 230027, China | 2003 | Cell Research2003,13,1: | 24 |
