Change next <td> text with JQuery
===

I have grid row scheme like:

    <tr>
    <td>110</td>
    <td><input class="client-chb" name="checkedRecords" type="checkbox" value="110" title="checkedRecords"></td>
    <td>Some name</td>
    <td>Some other name</td>
    <td>1.1.2012</td>
    </tr>

I have one function where i get all selected checkboxes , get thier values and send to the server via ajax.

But i want just before i make that ajax post, to get 3 & 4 <td> and change text style like

    <td><b>Some name</b></td>

I need this vice versa. Or to be more clear, this is "mark as read" and "mark as unread" message inbox.

      function MarkAsUnread() {
            var idata = new Array();
            $(".client-chb:checked").each(function() {
                var test = $(this);
    // maybe here, test -> find next td -> change text
                idata.push($(this).val());
            });
    //other logic
    }
