Reviewer: Jirong Huo  
 
Reviewer's report:  
The manuscript is much better and the response to reviewers are acceptable. How ever, several 
minor revisions are still necessary.  
 
1. Please carefully go through the manuscript and check the number in the table and manuscript, 
I found several mistakes: ie, a total of 132 patients (inclusion of 117 cases, while exclusion 
35 cases, shou ld be 152 cases?); 117 cases were included, but the total of male and female is 
100 in Table?  
2. It would be better the authors provided a patient select diagram.  
3. The language needs further editing by a native English scientist.
