Methods: Collect the English and Chinese investigation literature for pancreatic gland primarily occupation which were published and cited by MEDLINE and the core Chinese academic journals, with pathologic diagnosis. We collected 21 piece of writing, and reconsolidate these literatures, calculate the sensitivity, specificity, degree of accuracy, positive predictive value and negative predictive value, and 95% confidence interval.

In the middle rostrocaudal third of the red nucleus,the double-labelled neurons mainly occupied the ventromedial portions of the red nucleus.Injection of Bay K8644 (an L-Ca2+ channel agonist) in lateral ventricle induced immunoreactive intensity and did not change the distribution pattern of CaBP-LI positive rubrospinal neurons.

脑室注射L型钙离子通道激动剂Bay K8644 仅引起CaBP-LI免疫反应强度增加，并未改变两种神经元的分布方式，头侧CB-Au标认的红核-脊髓投射神经元仍表现CaBP-LI阴性。
