I tried both of the two methods, but I still cannot solve the problem.
To describe it well, I recorded my screen to here:

for online view: http://sssslang.8tt.org/pubfiles/gnus/index.html

for better quality(download then view use mplayer):

First, program notified me there are 13 new mails, then I start gnus,
but find it displays only 9. I checked the *Message* buffer. It should
be 13. Then I quit gnus and open it again, it shows 13 again :-/. But if
I enter a group and read some message before quit, the non-displayed
messages are gone.

I'm afraid my message will be lost. But I really like using Gnus. Now I
changed from no Gnus to Gnus 5.11, the problem still exist. Could
someone can help me? PLEASE.
