?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.

Objective To assess regional cerebrovascular reactivity (CVR) and cognition impairment of subcortical ischemic vascular disease (SIVD). To show whether CVR affects cognitive impairment of SIVD patients. Methods Arterial spin-labeling (ASL) by MR image was applied in measuring regional cerebral blood flow (rCBF) of frontal lobe, temporal lobe, parietal lobe, occipital lobes after 5% CO2 inhalation, and the CVR was demonstrated by increase rate of rCBF in all the subject areas. Results (1)The patients with SIVD had reduced CVR in cortex of frontal lobes, white matter of frontal lobes, temporal lobes and occipital lobes(P < 0.05). (2) CVR in the SIVD patients with cognitive impairment decreased in frontal cortex and white matter when compared with the patients without cognitive impairment(P < 0.01). Conclusion These results showed that CVR decreased significantly in cortical gray matter and white matter in elderly patients with SIVD. Also the reduction of CVR in the frontal cortex and white matter was associated with cognitive impairment.

Objectives To investigate the effect of magnetron sputtered niobium nitride (NbN) on the bonding strength of commercially pure cast titanium (Ti) and low-fusing porcelain (Ti/ Vita titankeramik system).Methods Sixty Ti specimens were randomly divided into four groups, group Tl, T2, T3 and T4.All specimens of group Tl and T2 were first treated with 120 μm blasted Al2O3 particles, and then only specimens of group T2 were treated with magnetron sputtered NbN film.All specimens of group T3 and T4 were first treated with magnetron sputtered NbN film and then only specimens of group T4 were treated with 120 μm blasted Al2O3 particles.The composition of the deposits were analyzed by X-ray diffraction (XRD).A universal testing machine was used to perform the three-point bending test to evaluate the bonding strength of Ti and porcelain.The microstructure of NbN, the interface of Ti-porcelain and the fractured Ti surface were observed with scanning electron microscopy (SEM) and energy depressive spectrum (EDS) , and the results were compared.Results The XRD results showed that the NbN deposits were cubic crystalline phases.The bonding strength of Ti and porcelain in Tl to T4 group were (27.2±0.8) , (43.1±0.6) , (31.4±1.0) and (44.9±0.6) MPa.These results were analyzed by one-way analysis of variance and differences between groups were compared using least significant difference test Significant inter-group differences were found among all groups (P<0.05).The results of SEM showed that with treatment of Al2O3 or NbN, alone, pre-cracks were found in the interface of Ti-porcelain, while samples treated with both Al2O3 and NbN had better bond.EDS of Ti-porcelain interface showed oxidation occurred in T1, T2 and T3, but was well controlled in T4.Conclusions Magnetron sputtered NbN can prevent Ti from being oxidized, and can improve the bonding strength of Ti/Vita titankeramik system.Al2O3 blast can also improve the bonding strength of Ti/Vita titankeramik system.

Background Posterior capsular opacification (PCO)affects the pseudoaccommodation of 1CU accommodative intraocular lens (1CU AIOL).At present,few studies on the effect of PCO and Nd∶ YAG laser capsulotomy on intraocular shifting of 1CU AIOL are published.Objective The present study was to evaluate the effect of PCO and Nd∶YAG laser capsulotomy on the shifting of 1CU AIOL.Methods A respective serial caseobservational study was designed.Written informed consent was obtained from each patient prior to this study.Twentyfour eyes of 20 patients with PCO after phacoemulsification and implantation of 1CU AIOL were included in this study.Ocular examination was performed 3 months after IOL implantation,1 day before Nd:YAG laser capsulotomy and 3 months after Nd∶YAG laser capsulotomy to evaluate the distance corrected near visual acuity(DCNVA).The difference in the anterior chamber depths before and after administering 1％ pilocarpine topical eye drops was measured with the IOLMaster to determine the intraocular shifts of the IOL.The extent of IOL shifting was compared among 3 time points to assess the factors influencing IOL accommodation after 1CU AIOL implantation.Results The shifting amplitude of 1CU AIOL was(0.44±0.21)mm 3 months after implantation of 1CU AIOL,(0.27±0.11)mm 1 day before Nd ∶ YAG laser capsulotomy,and (0.34±0.10) mm 3 months after Nd ∶ YAG laser capsulotomy,showing a significant difference among them(F=7.180,P=0.001).The shifting amplitude of 1CU AIOL significantly declined 1 day before Nd∶YAG laser capsulotomy in comparison with 3 months after implantation of 1 CU AIOL(P =0.006).The shifting amplitude 3 months after Nd∶YAG laser capsulotomy increased slightly in comparison with 1 day before Nd∶YAG laser capsulotomy(P=0.059).DCNVA was(3.1±0.9)J 3 months after implantation of 1CU AIOL,(6.2±0.8) J 1 day before Nd ∶ YAG laser capsulotomy and(3.4±0.7) J 3 months after Nd ∶ YAG laser capsulotomy,with a significant difference among them (F =110.270,P =0.000).DCNVA was lower 1 day before Nd∶ YAG laser capsulotomy than 3 months after implantation of 1CU AIOL(P＜0.05).However,DCNVA was higher 3 months after Nd∶YAG laser capsulotomy than that of 1 day before Nd∶YAG laser capsulotomy (P＜0.05).There was no significant correlations between DCNVA and IOL movement 3 months after IOL implantation,1 day before Nd∶ YAG laser capsulotomy and 3 months after Nd ∶ YAG laser capsulotomy (r1 =-0.150,P1 =0.486,r2 =-0.320,P2 =0.122,r3 =-0.100,P3 =0.633).Conclusions The shifting amplitude of 1CU AIOL markedly declines due to PCO.No clinically significant influence of Nd ∶ YAG laser capsulotomy on the shifting amplitude of 1 CU AIOL is found.DCNVA can improve after Nd∶YAG laser capsulotomy.Multiple inter-related factors concerning pseudophakic accommodation may influence DCNVA.
