(2S,3R,2 R,4E,8E)-N-(2 -hydroxyeicosanosyl)-9-methyl-1,3-dihydroxy2-amino-4,8-nonadecadiene(1),a new ceramide,together with two known compounds Δ4,5(E),Δ8,9(E)-sphingol-n-hexadecamide(2) and ergost-3β,5α,6β-triol(3) were isolated from the soft coral Cespitularia cocerulea May in the South Sea of China.

A known steroidal glycoside has been isolated from the soft coral Cespitularia cocerulea collected from the South China Sea.

Immunofluorescence localization of inclusion and identification of nonmuscle myosin heavy chain IIA in neutrophils of May-Hegglin anomaly patients;

May-Hegglin anomaly is a rare inherited autosomal dominant platelet disorder,caused by a mutation of the MYH9 gene,which localized on chromosome 22q12.

Treatment of distal tibial fracture with May plate;

Objective To discuss the therapeutic effects of May plate on intertrochanteric fractures.

In this paper, some important propositions on the May spectral sequence are first given, and then a new nontrivial family of homotopy elements is detected in the stable homotopy groups of spheres by the May spectral sequence and the Adams spectral sequence.

Using Adams spectral sequence and May spectral sequence, a new nonzero element is defected in the stable homotopy group of Smith-Toda spectrum V(1).

According to the fact that E~(s,t,*)_1 of May spectral sequence is convergee to E~(s,t)_A(Z_p,Z_p) and E~(s,t)_2 of Adams spectral sequence is converged to stable homotopy groups of sphere π_(t-s)(S)_p combined with the exact sequence of Ext group induced from the confibration of spectrum.
