1. Results: According to pathologic courses, NLM was classified into three types.

2. The present status and progress in study of nano luminescent materials (NLM) are reviewed in this paper.

3. Launching the initiative on January 25, Donald Lindberg, NLM director, said, "In light of the medical disaster unfolding in Haiti, it's hard to imagine a more urgent need.

4. The results show that two-level homomorphic NLM algorithm has the best performance from the aspects of background noise suppression, uniformity on the target and edge preserving.

5. NLM(National Library of Medicine)is the well known center of biological and medical sciences.

6. The author introduces the work which the NLM and NCLIS have done for improving the consumer health information service in America,(sentencedict.com/NLM.html) as well as successful examples of the health information service.

7. Medical literature analysis and retrieval system online(MEDLINE) established by National Library of Medicine, USA(NLM) is the most important biomedical database all over the world.

8. Therefore the sonography should be the first choice for the diagnosis of NLM.

9. Additionally, through the National Network of Libraries of Medicine (NN/LM) program, a division of NLM, user support in the form of phone, e-mail, and training is available free of charge.

10. Purpose : To assess the value of the sonographic diagnosis of non - lactation mastitis ( NLM ).

11. As other online databases were developed, MEDLARS became the name of the entire NLM information system while MEDLINE became the name of the premier database.

12. Materials and Methods: The duplex sonography of 28 patients with NLM were retrospectively analyzed, correlated with clinical and pathologic diagnosis.

13. The manuscript is a randomized trial, registered in the NLM database as NCT00931554.
