Tomato-rice rotation is prevalent in subtropical and tropical regions in China. This practice enhances crop productivity and the disease suppression property of soils against soil-borne plant pathogens. To explore the variations and dynamics of bacterial and fungal communities, bulk soil samples were collected during two consecutive years under a rotation system between tomato and rice originated from the year of 2010 in Hainan Island, and 16S rDNA and ITS amplicons were sequenced by Illumina MiSeq. The results demonstrated that potentially beneficial bacterial phyla Acidobacteria, Chloroflexi and genus Paenibacillus, as well as the fungal genus Mortierella were significantly enriched, while the potentially pathogenic fungal genus Fusarium was significantly decreased during the crop rotation. Measurements of soil physicochemical properties indicated that the soil acidification was improved. Redundancy analysis (RDA) revealed the correlation of the microbial community with soil pH and identified soil total phosphorus (TP) level as the highest determinant factor for both bacterial and fungal communities. This work provides a preliminary description of changes of the bacterial and fungal communities related to tomato-rice rotation in China and offered experimental evidences for exploring the effects of this agricultural practice on soil ecology.
Some atypical vertebral hemangiomas (VHs) may mimic metastases on routine MRI and can result in misdiagnosis and ultimately to additional imaging, biopsy and unnecessary costs. The purpose of this study is to assess the utility of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) on account of field-of-view optimized and constrained undistorted single shot (FOCUS) in distinguishing atypical VHs and vertebral metastases.
A total of 25 patients with vertebral metastases and 25 patients with atypical VHs were confirmed by clinical follow-up or pathology. E-64 mouse IVIM-DWI imaging was performed at different b values (0, 30, 50, 100, 150, 200, 400, 600, 800, 1000mm
/s). IVIM parameters [the true diffusion coefficient (D), pseudodiffusion coefficient (D*), standard apparent diffusion coefficient (ADC), and perfusion fraction (f)] were calculated and compared between two groups by using Student's t test. A receiver operating characteristic analysis was performed.
Quantitative analysis of standard ADC and D parameters showed significantly lower values in vertebral metastases when compared to atypical hemangiomas [ADC value (0.70 ± 0.12) × 10
mm
/s vs (1.14 ± 0.28) × 10
mm
/s; D value (0.47 ± 0.07) × 10
mm
/s vs (0.76 ± 0.14) × 10
mm
/s, all P < 0.01]. The sensitivity and specificity of D value were 93.8% and 92.3%, respectively.
The standard ADC value and D value may be used as an indicator to distinguish vertebral metastases from atypical VHs. FOCUS IVIM-derived parameters provide potential value in the quantitatively differentiating vertebral metastases from vertebral atypical hemangiomas.

The purpose of this study was to utilize the National Readmission Database (NRD) to determine estimates for complication rates, 90-day readmission rates, and hospital costs associated with spinal fusion in pediatric patients with Marfan syndrome.
The 2012-2015 NRD databases were queried for all pediatric (< 19years old) patients diagnosed with Marfan syndrome undergoing spinal fusion surgery. The primary outcome variables in this study were index admission complications and 90-day readmissions.
A total of 249 patients with Marfan syndrome underwent spinal fusion surgery between 2012 and 2015 (mean age ± standard deviation at the time of surgery 14 ± 2.0, 132 (53%) female). 25 (10.1%) were readmitted within 90days of the index hospital discharge date. Overall, 59.7% of patients experienced at least one complication during the index admission. Unplanned 90-day readmission could be predicted by older age (odds ratio 2.3, 95% confidence interval 1.3-4.2, p = 0.006), Medicaid insurance status (56.0, 3.8-8managed carefully perioperatively to reduce inpatient complications and early hospital readmissions.
Cervical radiculopathy is a common disabling cervical spine condition. Open anterior and posterior approaches are the conventional surgical treatment approaches with good clinical outcomes. However, the soft tissue damage in these procedures can lead to increase perioperative morbidity. Endoscopic spine surgery provides more soft tissue preservation than conventional approaches. We investigate the radiological and clinical outcomes of posterior endoscopic cervical foraminotomy and discectomy.
A prospective clinical and radiological study with retrospective evaluation were done for 25 patients with 29 levels of cervical radiculopathy who underwent posterior endoscopic cervical discectomy from November 2016 to December 2018. Clinical outcomes of Visual Analogue Scale, Neck Disability Index and MacNab's score were evaluated at pre-operative, post-operative 1week, 3months and final follow-up. Preoperative and post-operative final follow-up flexion and extension roentgenogram were evaluated for cervical stabilminal dimensions (1) sagittal area increased 21.4 ± 11.2 mm
, (2) CT Cranio Caudal length increased 1.21 ± 1.30mm and (3) CT ventro-dorsal length increased 2.09 ± 1.35mm and (4) 3D CT scan reconstruction coronal decompression area increased 536 ± 176 mm
, p < 0.05.
Uniportal posterior endoscopic cervical foraminotomy and discectomy are safe, efficient and precise choreographed set of technique in the treatment of cervical radiculopathy. It significantly improved clinical outcomes and achieved the objective of increasing in the cervical foramen size in our cohort of patients.
