Chemical fertilizer reduction combined with organic fertilizer affects the soil microbial community and diversity and yield of cotton.

Introduction: The soil microbial community plays an important role in modulating cotton soil fertility. However, the effects of chemical fertilizer combined with organic fertilizer on soil chemical properties, microbial community structure, and crop yield and quality in arid areas are still unclear. This study aimed to explore the effects of different organic fertilizers on soil microbial community structure and diversity and cotton growth and yield.

The prognostic value of regional lymph node metastases in patients of Guangdong Province, China with differentiated thyroid cancer: A multicenter retrospective clinical study.

Although the prognostic value of nodal metastases in differentiated thyroid cancer remains controversial, it is of interest to evaluate and understand the different characteristics of predictive outcomes.A multicenter retrospective study was conducted in 215 untreated patients with differentiated thyroid cancer from July 1997 to July 2015 in 4 medical centers of Guangdong Province.
