PHP Code:

$result = $vbulletin->db->query_read("
    SELECT mess FROM gb
    ORDER BY datum DESC limit 15
");

$output = '';
while ($row = $vbulletin->db->fetch_array($result)) 
{
    eval('$output.= "' . fetch_template('Your_Template') . '";');
} 


"Your_Template" would be used to format each line.

The resulting variable $output can then be included in the template you are using to display the whole page.
