Abstract (2. Language): 
By applying the differential subordination theorem, we further investigate the subclass Hn,  [ , ] of functions which are analytic in the unit disk. Several subordination results on a convex function and a incomplete beta function are obtained. Moreover, the function that belongs to the Hn,  [ , ] with a Cauchy-Euler differential equation is also discussed on similar subject. Our results extend some earlier works.
