If it has to be a regex:

^            # Start of string
(?=.*[A-Z])  # upper case (ASCII) letter
(?=.*[a-z])  # lower case letter
(?=.*\d)     # digit
(?=.*[\W_])  # symbol
\S           # no whitespace
{5,10}       # string length is >=5 and <=10
$            # end of string

or, if your regex flavor doesn't support verbose regexes:

^(?=.*[A-Z])(?=.*[a-z])(?=.*\d)(?=.*[\W_])\S{5,10}$
