2A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
3A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s).QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China 2003Chinese Science Bulletin2003,48,10:121
4基于IMRT时代的第八版AJCC/UICC鼻咽癌临床分期建议显示文摘目的准确的分期系统对癌症的治疗至关重要。随着癌症分期和治疗方法的演变,需要不断评价分期的适用性和改进性。方法基于第7版AJCC/UICC分期回顾性分析香港和中国大陆2个肿瘤中心收治的1609例接受调强放射治疗的首诊无转移鼻咽癌患者临床资料,所有患者治疗前均行核磁共振分期评估。结果无其他T3、T4期解剖结构受侵患者中,伴有咀嚼肌间隙(翼内肌和/或翼外肌)侵犯、椎前肌侵犯及咽旁间隙侵犯的三组患者之间0s相近。伴广泛软组织(上述侵犯结构以外的软组织)受侵患者OS与伴有颅内侵犯或颅神经侵犯相似。仅2%患者锁骨上窝以上淋巴结转移者直径〉6cm,其0s率与下颈淋巴结转移者类似。用下颈(环状软骨尾侧缘水平以下)代替锁骨上窝并不影响N分期之间的风险差异性。采用推荐的T、N分期,T。N。、T。N,期0s相近。结论经AJCC/UICC分期筹备委员会审阅后,建议第8版分期应将翼内肌/翼外肌从T。降到T:期,增加椎前肌为L期,用下颈取代锁骨上窝,将淋巴结最大直径〉6cm合并归为N,期,将T。、N,期统一归为Ⅳ。期。这些改变不仅使得相邻分期间风险差异性更好,而且使得临床实践性与全球适用性之间达到最佳平衡。潘建基 Wai Tong Ng 宗井凤 Lucy L.K.Chan Brian O' Sullivan 林少俊 Henry C.K.Sze 陈韵彬 Horace C.W.Choi 郭巧娟 Wai Kuen Kan 肖友平 Xu Wei Quynh Thu Le Christine M.Glastonbury A.Dimtrios Colevas Randal S.Weber Jatin P.Shah Anne W.M.Lee 2016中华放射肿瘤学杂志2016,25,3:65
5Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF.Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun 2018Science China(Life Sciences)2018,61,12:43
6Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47
7Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma显示文摘AIM:To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma(ICC). METHODS:We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003.Of these,429(8.1%)patients were diagnosed with ICC,and their clinicopathological, surgical,and survival characteristics were analyzed. RESULTS:Upper abdominal discomfort or pain(65.0%), no symptoms(12.1%),and hypodynamia(8.2%)were the major causes for medical attention.Laboratory tests showed 198(46.4%)patients were HBsAg positive, 90(21.3%)hadα-fetoprotein>20μg/L,50(11.9%) carcinoembryonic antigen>10μg/L,and 242(57.5%) carbohydrate antigen 19-9(CA19-9)>37 U/mL.Survival data was available for 329(76.7%)patients and their mean survival time was 12.4 mo.The overall survival of the patients with R0,R1 resection and punching exploration were 18.3,6.6 and 5.6 mo,respectively. Additionally,CA19-9>37 U/mL was associated with lymph node metastases,but inversely associated withcirrhosis.Multivariate analysis indicated that radical resection,lymph node metastases,macroscopic tumor thrombi and size,and CA19-9 were associated with prognosis. CONCLUSION:Surgical radical resection is still the most effective means to cure ICC.Certain laboratory tests(such as CA19-9)can effectively predict the survival of the patients with ICC.Wei-Feng Shen Wei Zhong Feng Xu Tong Kan Li Geng Feng Xie Cheng-Jun Sui Jia-Mei Yang 2009World Journal of Gastroenterology2009,15,47:39

9Future changes in thermal comfort conditions over China based on multi-RegCM4 simulations显示文摘使用4个不同全球模式模拟结果,驱动RegCM4区域气候模式,进行了RCP4.5中等温室气体排放情景下东亚地区21世纪气候变化的高分辨率(25 km)模拟。本文基于此套模拟集合,使用综合考虑了气温、相对湿度和风速因素的人体热感受指数有效温度(ET),给出了未来中国区域热舒适条件的变化。分析中同时考虑了未来人口数量和分布情景所引起的暴露度变化。研究发现,未来中国区域的ET的普遍升高引起炎热天气的人口暴露度大幅度增加(到21世纪末相对于当代全国平均将增加6倍‘人-天’(person–days),凉、冷和寒冷天气的暴露度则减少。同时尽管舒适日数有所增加,但相应的人-天数目则有22%的减少。不同因素(气候、人口和两者的相互作用)对于上述变化的贡献分析表明,在舒适度的热端,气候因素的作用更重要,而人口因素则在冷端起着主导作用。总体而言,即使是在中等水平温室气体排放情景下,中国区域未来的热强度也将增加,尽管结果表现出很强的地理依赖特征。相对使用单纯气候因素的结果,人口暴露度的引入对变化信号有着强烈的调制作用,从而更加强调了在与气候变化相关的风险评估分析中,考虑社会-经济因素的重要性。GAO Xue-Jie WU Jie SHI Ying WU Jia HAN Zhen-Yu ZHANG Dong-Feng TONG Yao LI Rou-Ke XU Ying GIORGI Filippo 2018Atmospheric and Oceanic Science Letters2018,11,4:30
10Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases.Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang 2020Genomics, Proteomics & Bioinformatics2020,18,6:29

12Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background:As a large,prospective,multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF),the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score(COSSH-ACLFs),has been approved by some foreign scholars;however,its predictive value needs to be verified.This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.Methods:This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014.Spearman method was used to assess the correlation of COSSHACLFs with classical scores.Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF,and stratified analysis was used to further verify the stability of this relationship.We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve(AUROC)and Z-test.Results:A total of 975 patients with HBV-ACLF were screened,and 751 were analyzed(623 male and 128 female).COSSH-ACLFs was the highest in patients with end-stage ACLF,followed by those with middle-and early-stage ACLF(H=211.8,P<0.001).In the fully adjusted model,COX multivariate regression analysis revealed that COSSH-ACLFs(as a continuous variable)was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days(hazard ratio[HR]:1.37[1.22,1.53],P<0.001)and 90 days(HR:1.43[1.29,1.58],P<0.001).The same trend could be observed in the crude model and minimally adjusted model.The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792,respectively,indicating a stronger predictive accuracy than those of classic models.Conclusions:COSSH-ACLFs,with a superior predictive accuracy compared with other classical scores,can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.Jing-Jing Tong Wei Zhao Xiu-Ying Mu Xiang Xu Hai-Bin Su Xiao-Yan Liu Jing Chen Xing-Ran Zhai Yu Wang Jin-Hua Hu 2019Chinese Medical Journal2019,,13:27
13Air pollution characteristics and their relationship with emissions and meteorology in the Yangtze River Delta region during 2014–2016显示文摘With rapid economic growth and urbanization, the Yangtze River Delta(YRD) region in China has experienced serious air pollution challenges. In this study, we analyzed the air pollution characteristics and their relationship with emissions and meteorology in the YRD region during 2014–2016. In recent years, the concentrations of all air pollutants, except O3,decreased. Spatially, the PM2.5, PM10, SO2, and CO concentrations were higher in the northern YRD region, and NO2 and O3 were higher in the central YRD region. Based on the number of non-attainment days(i.e., days with air quality index greater than 100), PM2.5 was the largest contributor to air pollution in the YRD region, followed by O3, PM10, and NO2.However, particulate matter pollution has declined gradually, while O3 pollution worsened.Meteorological conditions mainly influenced day-to-day variations in pollutant concentrations. PM2.5 concentration was inversely related to wind speed, while O3 concentration was positively correlated with temperature and negatively correlated with relative humidity.The air quality improvement in recent years was mainly attributed to emission reductions.During 2014–2016, PM2.5, PM10, SO2, NOx, CO, NH3, and volatile organic compound(VOC)emissions in the YRD region were reduced by 26.3%, 29.2%, 32.4%, 8.1%, 15.9%, 4.5%, and0.3%, respectively. Regional transport also contributed to the air pollution. During regional haze periods, pollutants from North China and East China aggravated the pollution in the YRD region. Our findings suggest that emission reduction and regional joint prevention and control helped to improve the air quality in the YRD region.Tao Ma Fengkui Duan Kebin He Yu Qin Dan Tong Guannan Geng Xuyan Liu Hui Li Shuo Yang Siqi Ye Beiyao Xu Qiang Zhang Yongliang Ma 2019Journal of Environmental Sciences2019,31,9:26
14Risk factors for early recurrence of small hepatocellular carcinoma after curative resection显示文摘BACKGROUND:Poorer prognosis is seen in patients with hepatocellular carcinoma (HCC) after curative hepatic resection with early recurrence (≤1 year) than in those with late recurrence (>1 year).This study aimed to identify risk factors for postoperative early recurrence of small HCC (≤3 cm in diameter).METHODS:The study population consisted of 158 patients who underwent curative resection for small HCC between January 2002 and July 2004.Risk factors for early recurrence were analyzed.RESULTS:Thirty-three (20.8%) patients developed early recurrence after surgery.Univariate analysis showed the following significant risk factors for early recurrence in small HCC:serum alpha-fetoprotein (AFP) level >100 ng/ml,lack of tumor capsule formation,microscopic vascular invasion,high Edmonson-Steiner grades,and cytokeratin-19 (CK-19) expression (P<0.05).Multivariate stepwise logistic regression analysis showed that serum AFP level >100 ng/ml (odds ratio 2.561,95% confidence interval 1.057 to 6.206,P=0.037) and microscopic vascular invasion (odds ratio 4.549,95% confidence interval 1.865 to 11.097,P=0.001) were independent factors.CONCLUSIONS:Postoperative early recurrence is related to serum AFP level >100 ng/ml and microscopic vascular invasion in patients with small HCC.Adjuvant therapy and careful follow-up are required for patients with these risk factors.Zhou, Yan-Ming Yang, Jia-Mei Li, Bin Yin, Zheng-Feng Xu, Feng Wang, Bin Xu, Wen Kan, Tong 2010Hepatobiliary & Pancreatic Diseases International2010,9,1:24
15Relationship between hs-CRP, proMMP-1, TIMP-1 and coronary plaque morphology: intravascular ultrasound study显示文摘Background Rupture of unstable plaque with subsequent thrombus formation is the common pathophy- siological substrate of the acute coronary syndrome (ACS). It is of potential significance to explore the blood indexes predicting plaque characteristics. Little studies have focused on this field. Therefore we investigated the relationship between hypersensitive C-reactive protein (hs-CRP), pro-matrix metalloproteinase-1 (proMMP-1), tissue inhibitors of matrix metalloproteinase-1 (TIMP-1) and coronary plaque morphology. Methods Intravascular ultrasound (IVUS) examination was done in 152 patients with confirmed coronary heart disease before percutaneous coronary intervention from February 2003 to July 2005. Plasma samples of arterial blood were collected prior to the procedure. The level of hs-CRP, proMMP-1 and TIMP-1 were respectively measured by enzyme-linked immunosorbent assay (ELISA). Results Unstable and ruptured plaque were found more frequently in patients with acute myocardial infarction and unstable angina. External elastic membrane cross-sectional area (EEM CSA), plaque area, lipid pool area and plaque burden were significantly larger in ruptured and unstable plaque group. Positive remolding, thinner fabric-cap, smaller minimal lumen cross-sectional area (MLA), dissection and thrombus were significantly more frequent in ruptured and unstable plaque group. The levels of plasma hs-CRP, proMMP-1 and TIMP-1 were higher in ruptured plaque group. hs-CRP>8.94 mg/L was used to predict ruptured plaque with a ROC curve area of 0.76 [95% confidence interval (CI), 67.0%-85.8%], sensitivity of 71.8%, specificity of 77.0% and accuracy of 69.2% (P<0.01), similarly for proMMP-1>0.12 ng/ml with a ROC curve area of 0.69 [95% CI, 58.2%-80.2%], sensitivity of 69.2%, specificity of 75.2% and accuracy of 66.2% (P<0.01), and TIMP-1>83.45 ng/ml with a ROC curve area of 0.67 [95% CI, 56.2%-78.3%], sensitivity of 66.7%, specificity of 61.9% and accuracy of 66.2% (P<0.01). Conclusion The plaque characteristics correlate with the clinical presentation. The elevation of hs-CRP, proMMP-1 and TIMP-1 are related to the plaque instability and rupture.ZHANG Xing-wei GE Jun-bo YANG Jian-min GE Lei WANG Ning-fu GAO Yan LI Pei-zhang PAN Hao TONG Guo-xin ZHOU Liang YE Xian-hua XU Jian 2006Chinese Medical Journal2006,,20:23

20Effects of urea and(NH_4)_2 SO_4 on nitrification and acidification of Ultisols from Southern China显示文摘The mechanisms for the effects of ammonium-based fertilizers on soil acidification in subtropical regions are not well understood.Two Ultisols collected from cropland and a tea garden in Anhui and Jiangxi Provinces in subtropical southern China,respectively,were used to study the effects of urea and(NH 4) 2 SO 4 on the nitrification and acidification of soils with incubation experiments.Nitrification occurred at very low pH with no N fertilizer added and led to lowering of the soil pH by 0.53 and 0.30 units for the soils from Jiangxi and Anhui,respectively.Addition of urea accelerated nitrification and soil acidification in both Ultisols;while nitrification was inhibited by the addition of(NH 4) 2 SO 4,and greater input of(NH 4) 2 SO 4 led to greater inhibition of nitrification.Ammonia-oxidizing bacteria(AOB) played an important role in nitrification in cropland soil under acidic conditions.Addition of urea increased the soil pH at the early stages of incubation due to hydrolysis and stimulated the increase in the AOB population,and thus accelerated nitrification and soil acidification.At the end of incubation,the pH of Ultisol from Jiangxi had decreased by 1.25,1.54 and 1.84 units compared to maximum values for the treatments with 150,300 and 400 mg/kg of urea-N added,respectively;the corresponding figures were 0.95,1.25 and 1.69 for the Ultisol from Anhui.However,addition of(NH 4) 2 SO 4 inhibited the increase in the AOB population and thus inhibited nitrification and soil acidification.Soil pH for the treatments with 300 and 400 mg/kg of(NH 4) 2 SO 4-N remained almost constant during the incubation.AOB played an important role in nitrification of the cropland soil under acidic conditions.Addition of urea stimulated the increase in the AOB population and thus accelerated nitrification and soil acidification;while addition of(NH 4) 2 SO 4 inhibited the increase in the AOB population and thus inhibited nitrification.Dell Tong Renkou Xu 2012Journal of Environmental Sciences2012,24,4:21
