AIM:To investigate the findings of the eyes which were examined preoperatively by three mirror contact lens before the implantation of implantable collamer lens ( ICL) . To analysis the retinal pathological changes and to explore the clinical analysis of early diagnosis and treatment in retinopathy on fundus examination before operation.
METHODS:The retrospective case series study included 127 eyes of 64 patients who underwent phakic intraocular lens implantation were received the fundus examination by three mirror from April 2011 to April 2012 in our hospital. The age, refractive diopter, the findings of Goldmann three mirror examination and the condition of retinal photocoagulation were analysed and concluded.RESULTS:A total of 34 eyes (26. 8%) out of all 127 eyes ( 64 cases ) were found to have peripheral retinal pathological changes. Eight eyes ( 6. 3%) with retinal holes, 15 eyes(11. 8%) with retinal lattice degeneration, 5 eyes ( 3.9%) with retina cream degeneration, 3 eyes (2.4%)with retinal paving stone degeneration,2 eyes with vitreoretinal adhesion and traction, 1 eye ( 0. 8%) with retinal hemorrhage. Twenty-five cases were given retinal photocoagulation and then received the ICL implantation after 3mo. The follow - up time was 1a. No retinal detachment happened.
CONCLUSION: Phakic before intraocular lens implantation for fundus examination by three mirror is contributed to find the peripheral retinal pathological changes and abnormity. And make the appropriate treatment before operation for improving the security of operation, it can also give help to the postoperative follow-up of the fundus of these patients.

?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

Chlamydial infection in human urogenital tract induces inflammation and causes tissue damage and scarring. It is thought that cytokine production by the Chlamydia-infected cells plays a key role in chlamydial disease processes. Although many cytokines have been detected during chlamydial infection, little is known about the molecular mechanisms on how Chlamydia triggers and sustains the inflammatory cytokine cascades. In the current study, chlamydial infection of the human cervical epithelial cell line HeLa cells can induce the production of IL-8, IL-1α, IL-1β and IL-6. Using inhibitors for probing intracellular kinase signaling pathways required for the Chlamydia-induced cytokines, it was found that the Chlamydia-activated MAPK / P38 pathway is required for the chlamydial induction of IL-1α and IL-6 while both the Chlamydia-activated MAPK/ERK and MAPK/P38 pathways contribute to the production of IL-8.

AIM:To compare the efficacy and safety of intravitreal ranibizumab to those of triamcinolone acetonide ( TA ) injection for the treatment of macular edema secondary to central retinal vein occlusion ( CRVO) .
METHODS:This retrospective study included 40 eyes of 40 patients with macular edema associated with CRVO. Twenty patients 20 eyes were treated with intravitreal injection of triamcinolone acetonide (1mg, 0. 1mL), the other 20 patients 20 eyes accepted intravitreal ranibizumab (0. 5mg, 0. 05mL). The change of best corrected visual acuity ( BCVA ) , central macular thickness ( CMT ) , and intraocular pressure ( IOP ) before treatment and at 1, 2wk, 1, 2,3,6mo post-injection in the two groups were observed.
RESULTS:BCVA was improved at 1, 2wk, 1, 2,3,6mo post-injection in the TA group (P<0.05) and ranibizumab group ( P<0. 05 ). No significant difference was found between the two groups ( P > 0. 05 ). CMT decreased significantly within each group ( P < 0. 05 ), and no significant difference between groups was found ( P >0.05). In the TA group, the IOP was significantly higher at 2wk and 4wk than before treatment (P<0. 05). In the ranibizumab group, no elevated IOP was observed at 1, 2wk, 1, 2,3,6mo (P>0. 05). However, the IOP at 1mo was significantly higher in the TA group than that in the ranibizumb group (P<0. 05).
CONCLUSION:Intravitreal ranibizumab is an effective and safe treatment method for macular edema secondary to CRVO. It can effectively improve BCVA and reduce CMT without ocular and systemic complications compared with intravitreal TA.

Objective:The abstraction of characteristics in CT perfusion image is crucial in the clinical diagnosis of brain infarction and cerebral tumor.Methods:After describing the relevant parameters of CT cerebral perfusion imaging,such as cerebral blood flow (CBF),cerebral blood volume (CBV),the mean transition time (MTT) and the permeability surface (PS).With using Visual C ++ programming and CT scan images sequence obtained,the time-density curves of the brain tumor region were visualized.The more accurate hemodynamic parameters were calculated through an improved algorithm basing on the deconvolution and measuring method of the length,angle,area and other parameters.Conclusion:The quantitative analysis of feature parameter is of great benefit to clinical doctor in making timely diagnosis and treatment of brain tumor.

0.05).There were more complaints of postoperative pain and discomfort after LASEK procedure.No severe vision threatening complications in these two groups were found.Conclusion:Both LASIK and LASEK are safe and effective in treating eyes with severe myopia.
