?AlM:To investigate the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system before and after laser peripheral iridectomy (LPl) in primary angle-closure suspetive (PACS).
? METHODS: Sixty eyes of 33 PACS patients were enrolled in this study. Pentacam examination was performed before and 1d after LPl to measure the central anterior chamber depth ( CACD ) , the peripheral anterior chamber depth ( PACD ) , the anterior chamber volume ( ACV) and the peripheral anterior chamber angle ( ACA) . Statistical analysis used paired t test.
?RESULTS: There was no statistical significance on the changes of ACD. PACD and ACV increased significantly between before and 1d after LPl. ACA was widened from (22. 26o±5. 18o) to (26. 42o±5. 20o), which were increased significantly between before and 1d after LPl.
?CONCLUSlON: LPl can deepen the PACD and increase the ACV in PACS. PACD and ACV are the sensitive parameters of the anterior chamber changes with Pentacam anterior segment analysis system.

Alzheimers disease (AD) is a neurodegenerative disorder severely affecting the aged population. Its pathological hallmarks include amyloid plaques, neurofibrillary tangles, loss of synapes and neurons as well as brain inflammation. This review focuses on multiple roles of p38MAPK, one of the members of mitogen-activated protein kinases(MAPK) family, in the pathogenesis and progression of AD. The review discusses the evidences of p38 activation in AD models, its connection with each pathological mark of AD and the interaction between p38 and significant pathophysiological process, such as inflammation, neuronal apoptosis and hyperphosphorylation of tau. Moreover, a discussion is also made to address the basis of p38 as the target for therapeutic intervention in AD. All in all, p38 is considered to be a new promising target for drugs to control the progression of AD.

MicroRNAs (miRNAs) are small non-coding RNAs that contain 22 to 25 nucleotides and play important roles in post-transcriptional regulation of target genes. MiRNAs are involved in cell proliferation, differentiation, apoptosis, inflammation, and cancer development. Alveolar bone resorption is the main clinical manifestation of periodontitis. Osteoclasts are unique cells regulated by osteoblasts and inflammatory cytokines and are responsible for bone resorption in periodontitis. Recently, miRNAs have emerged as an important regulator of osteoclast differentiation and function. In this study, we review the recent research progress on the effects of miRNAs on osteoclast differentiation and function, particularly the mechanisms of miRNAs-mediated osteoclast formation and bone loss in periodontitis.
