In patients with clinically negative lymph nodes, sentinel lymph node biopsy (SLNB) instead of axillary lymph node dissection (ALND) has no difference in regional control, disease-free and overall survival, and can improve quality of life and upper limb function [1–4]. The combination of patent blue and radioisotope can provide the success rate of sentinel lymph node (SLN) detection [3], but these approaches present specific advantages and drawbacks.

AbstractA smooth shaft production process is important to ensure the safe and efficient development of mineral resources. Due to the influence of ore rock and the mismatch between rock size and ore pass design, an arching phenomenon occurs frequently during actual ore pass release, stagnating production. Therefore, an ore pass release simulator with a freely variable ore pass angle and height is designed and used to conduct a four-factor, five-level orthogonal ore pass release experiment.

National farmers surveyTo clarify the actual nutrient inputs of various crops in China, a national survey of 6.6 million farmers in 2,013 counties was conducted from 2005 to 2014. Farmers were interviewed face-to-face by local agricultural extension agents, using a standardized questionnaire that consisted of closed-ended questions. These questions were designed to obtain information regarding crop type, yields, manure source, and fertilizer use.
