I think you can try contents() to select the text node next to the checkbox you want and remove it.
However, I think it might not work in IE6/7.
try this
$(function(){
$('input:checkbox').parents().contents()
.filter( function(index){return (this.nodeType === 3 && $('input:checkbox').parents().contents().eq(index-1).attr('name') === 'ch1' ); }).remove();
});
