?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.

Background Establising the culture model of Müller cells for obtaining the highly putified target cells is essential for the study about the physiology and pathology of retinal Müller cells. The exsiting purifing method for culturing Müller cells is dissatisfactory. Objective This study was to establish a method to obtain high purifing Müller cells. Methods The retina from 5 clean newborn SD rats were isolated and digested by 0. 01% trypsin and cultured in DMEM containing 10% fetal bovine serum. The cellular suspension was then prepared,and the target cells were screened using flow cytometry based on the size and the quantity of cells. Cultured and passaged cells were identified by transmission electron microscope and light microscope. Immunocytochemistry was used to detecte the expression of GFAP in cultured cells for the determination of type and purity of the cells. Results The cells showed the similar shape to retinal Müller cells after primarily culture with the large volume, and some small other types of cells could been seen. The growth of cells was quickly 3 weeks later. The fibroblasts were removed using sticking-wall by steps,and neurons were eliminated following passage. Aboundent of cellular organs were seen under the transmission electron microscope. The positive response rate of the cells for CFAP was 100%. Conclution Flow cytometry offer a rapid and feasible approach for purifying Muller cell and it builds the foundation for further study about Müller cells.

Objective To study the expression of signal transducers and activators of transcription 3(STAT3) in airway epithelial cells of asthmatic mouse model and its association with airway remodeling,explore the role of signal-transduction pathway in airway remodeling.Methods Thirty Balb/c mice were randomly divided into normal control group(n=10),asthma without intervention group(n=10) and AG490 intervention group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining,total brochial wall thickness(Wat)and smooth muscle thickness(Wam) were measured by image analysis system,the percentages of collagen deposition were detected by Masson′s trichrome staining,the expression of STAT3 in airway were detected by immunohistochemistry technique;lung tissue extracts were analyzed for phosphorylation of STAT3(p-STAT3)by Western blot.SPSS 13.0 software was used to analyze the data.Results 1.The histological changes including airway thickness,airway smooth cell proliferation and excessive collagen deposition in subepithelial aera were found under light microscope in asthmatic mice.2.The level of STAT3 and p-STAT3 in asthma without intervention group were significantly higher than those in normal control group(Pa

Objective To observe the effects of inhaled budesonide (BUD) in early phase on the airway inflammation in asthmatic mouse,and its effects on the IL-6/signal transducers and activators of transcription 3(IL-6/STAT3 )signaling pathway in airway,explore the therapeutic target of BUD.Methods Forty Balb/c mice were randomly divided into control group(n=10),asthma group(n=10),BUD group(n=10) and AG490 group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining.The levels of IL-4,IL-5 and IL-6 in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay.Lung tissue extracts were analyzed for total STAT3 and phospho-STAT3(p-STAT3) by Western blot.Results 1.The levels of inflammatory cells,EOS%, IL-4,IL-5 and IL-6 levels in the BALF in BUD group were significantly lower than those in asthma group (Pa0.05).Conclusions Inhaled corticosteroid can apparently ameliorate airway inflammation in early phase in asthmatic mouse model,and it can downregulate the expressions of IL-6 and STAT3,inhibit the signal-transduction pathway of STAT3.The IL-6 /STAT3 signaling pathway of airway may be one of the potential therapeutic targets of inhaled corticosteroid.
