1N_2O emissions from agricultural soils in the North China Plain: the effect of chemical nitrogen fertilizer and organic manure显示文摘An enclosed chamber technique was used to measure N 2O emissions from intensively agricultural soils of the North China Plain during the periods of 1995—1996 and 1997—1998, to reflect distinct components of winter wheat and summer maize growing seasons. The results showed that the continuous application of fertilizer in agricultural soils increased N\-2O emissions by a factor of 24.1—28.1, the calculated annual chemical N fertilizer\|transformed N\-2O\|N emissions was 0.67%. Our results indicated that the application of organic manure also had a significant influence on soil N 2O emissions, which combined with the use of chemical N increased about 20% in a year. It was calculated that there were about 0.11% N of organic manure transformed as N 2O N. Annual mean N 2O emission from our study area of fertilized soils was estimated to be 57.1 μgN 2O/(m 2·h). A weak correlation was also found between N 2O emissions and soil available nitrogen content NH + 4.DONG Yun\|she 1,2,3 , Dieter Scharffe 2, Manfred Domroes 3, QI Yu chun 1, ZHANG Shen 1 (1.

4Ipsilateral breast tumor recurrence in early stage breast cancer patients treated with breast conserving surgery and adjuvant radiation therapy: Concordance of biomarkers and tumor location from primary tumor to in-breast tumor recurrence显示文摘BACKGROUND Patients with an in-breast tumor recurrence(IBTR)after breast-conserving therapy have a high risk of distant metastasis and disease-related mortality.Classifying clinical parameters that increase risk for recurrence after IBTR remains a challenge.AIM To describe primary and recurrent tumor characteristics in patients who experience an IBTR and understand the relationship between these characteristics and disease outcomes.METHODS Patients with stage 0-II breast cancer treated with lumpectomy and adjuvant radiation were identified from institutional databases of patients treated from 2003-2017 at our institution.Overall survival(OS),disease-free survival,and local recurrence-free survival(LRFS)were estimated using the Kaplan Meier method.We identified patients who experienced an isolated IBTR.Concordance of hormone receptor status and location of tumor from primary to recurrence was evaluated.The effect of clinical and treatment parameters on disease outcomes was also evaluated.RESULTS We identified 2164 patients who met the eligibility criteria.The median follow-up for all patients was 3.73[interquartile range(IQR)2.27-6.07]years.Five-year OS was 97.7%(95%CI:96.8%-98.6%)with 28 deaths;5-year LRFS was 98.0%(97.2-98.8)with 31 IBTRs.We identified 37 patients with isolated IBTR,19(51.4%)as ductal carcinoma in situ and 18(48.6%)as invasive disease,of whom 83.3%had an in situ component.Median time from initial diagnosis to IBTR was 1.97(IQR:1.03-3.5)years.Radiotherapy information was available for 30 of 37 patients.Median whole-breast dose was 40.5 Gy and 23 patients received a boost to the tumor bed.Twenty-five of thirty-two(78.1%)patients had concordant hormone receptor status,HER-2 receptor status,and estrogen receptor(ER)(P=0.006)and progesterone receptor(PR)(P=0.001)status from primary to IBTR were significantly associated.There were no observed changes in HER-2 status from primary to IBTR.The concordance between quadrant of primary to IBTR was 10/19[(62.2%),P=0.008].Tumor size greater than 1.5 cm(HR=0.44,95%CI:0.22-0.90,P=0.02)and use of endocrine therapy upfront(HR=0.36,95%CI:0.18-0.73,P=0.004)decreased the risk of IBTR.CONCLUSION Among patients with early stage breast cancer who had breast conserving surgery treated with adjuvant RT,ER/PR status and quadrant were highly concordant from primary to IBTR.Tumor size greater than 1.5 cm and use of adjuvant endocrine therapy were significantly associated with decreased risk of IBTR.Juhi M Purswani Fauzia Shaikh S Peter Wu Jennifer Chun Kim Freya Schnabel Nelly Huppert Carmen A Perez Naamit K Gerber 2020World Journal of Clinical Oncology2020,11,1:2
