Ultrasonographic Diagnosis of Intussusception in Children: A Systematic Review and Meta-Analysis.

Ultrasonography offers a unique advantage in the clinical diagnosis of intussusception. We aimed to evaluate the diagnostic accuracy of ultrasonography in pediatric intussusception. The PubMed, Embase, Web of Science, Cochrane Library databases, and African Journals Online database were searched for studies pertaining to ultrasonographic diagnosis of intussusception in children.

Conventional Ultrasound and Contrast-Enhanced Ultrasound in the Diagnosis of Splenic Diseases: A Systematic Review and Meta-analysis.

Accurate diagnosis of splenic diseases is important for timely and accurate treatment. The objective of this study was to compare the accuracy of contrast-enhanced ultrasound (CEUS) and conventional ultrasound (US) in detecting splenic lesions. A systematic literature search was undertaken, and 8 studies met the inclusion criteria.

Prognostic value of long non-coding RNA ATB in digestive system cancers: A meta-analysis.

Background: The present meta-analysis has evaluated the association between lncRNA ATB, prognosis and clinicopathological parameters in patients with digestive cancers.

Methods: Eligible studies were gathered from Web of Science, PubMed, Embase, Cochrane Library, WanFang databases and China National Knowledge Infrastructure (up to October 15, 2019). Hazard ratios (HRs) and 95 % confidence intervals (CIs) were calculated to estimate the prognosis and clinicopathological parameters of lncRNA ATB in patients with digestive cancers.

Response of height, dry matter accumulation and partitioning of oat (Avena sativa L.) to planting density and nitrogen in Horqin Sandy Land.

Nitrogen fertilizer application and planting densities were key limiting factor for the physiological metabolism and growth of Avena sativa L. In the paper, it was set five nitrogen fertilizer application (including: N1:225 kg/hm, N2:300 kg/hm, N3:375 kg/hm, N4:450 kg/hm, N5:525 kg/hm) and four planting densities (including M1:3 million plants/hm, M2:3.5 million plants/hm, M3:4 million plants/hm, M4:4.

Diagnostic performance of contrast-enhanced ultrasound for pancreatic neoplasms: A systematic review and meta-analysis.

Background: Early diagnosis of pancreatic cancer is essential to optimize treatment strategies.

Objectives: To evaluate the diagnostic performance of contrast-enhanced ultrasound for benign and malignant pancreatic neoplasms.

Data Sources: Pubmed, Embase, Web of Science, and Cochrane Library databases.
