ayan - in the save (button?) callback, just extract the data from the listbox as

 lbData = get(handles.listbox1,'String');

where listbox1 is the name/tag for your listbox control. You can then save the lbData variable to a mat file or text file. If the data is a cell array, see export cell array to text file for details.

MATLAB: Listbox content from structure hierarchy (GUIDE)

Here "Car" etc are the "fields", not the "subfields" (which would mean something like: DataBase.Vehicle.Car).

DataBase.Car = 1;
DataBase.Bus = 2;
DataBase.Motorbike = 3;
List = fieldnames(DataBase);
uicontrol('Style', 'listbox', 'String', List);

Keeping the listbox "updated" when the struct is changed, is very complicated. You need an object oriented approach to start a callback, when the data are changed. But you can fake it by not adding further fields manually, but when you use a dedicated function for this:

function S = myAddField(S, Field, Data)
S.(Field) = Data;
updateGui(S);   % <-- Implementation depends on your GUI
