Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 4,   Pages 406-417 doi: 10.15302/J-FASE-2020359

Abstract: Poor soil fertility due to low nutrient inputs is a major factor limiting grain production in Kenya.Increasing soil fertility for crop productivity in China has implications for food security in Kenya.study was therefore to investigate the historical patterns of grain production, nutrient inputs, soil fertilityHence, a beneficial cycle between soil fertility and plant growth in Quzhou grain production was developedthere was only a slight increase in grain yields in Kenya over this period, resulting from low soil fertility

Treatment of retaining reproductive function?in cesarean scar pregnancy：A clinical analysis of 46 cases

Guan Rui,Liu Yuhuan,Xu Mingjuan,Zhang Junjie,Hui Ning,Cui Ying

Strategic Study of CAE 2015, Volume 17, Issue 6,   Pages 45-49

Abstract:

To investigate the treatment methods of retaining reproductive function in cesarean scar pregnancy. Clinical datus of 46 casesSin our hospital during 2000―2014Swere analyzed retrospectively.SThere were 45 cases of first-trimesterSpregnancy andS1 case of second-trimester pregnancy. 13 casesS(28.9 %)Sof first-trimesteSpregnancy were misdiagnosed and had received artificial abortion before hospitalization. According to CSP classificationS,S19Scases were type I,S13 cases were Stype II,Sall cases wereSsuccessful inSretaining the uterus. 63.1 % of type IScases receivedSuterine curettage under ultrasoundSmonitoring,S21%Sof type I casesSreceivedSuterineScurettageSafter uterine artery embolizationS(UAE)S. 84.6 %Sof type IIScases received surgery in which lesion were resected and uterine scar were repaired. The csp patient of second-trimester pregnancy suffered from thrombosis of lower extremity and rebleeding 30 days after UAE, she received the surgery of resecting lesion. Conclusion: STheSkeySforStheSconservativeStreatmentSSofS CSPSSis early diagnosis and early treatment. TreatmentSshouldSbeSindividualizedSaccording to CSP clinicSclassification ,β-HCG and so on.Furthermore, there are still someSrisk of UAE.WeSshould be careful to select UAESfor patients.
