Objective To investigate the related factors of effects on distant visual acuity after photodynamic therapy (PDT) for choroidal neovascularization (CNV). Methods One hundred and thirty-five cases (135 eyes) of CNV treated with PDT were observed. The gender, preoperative distant and near visual acuity, disease course, pathogeny, area of CNV, types of CNV ascertained by fundus fluorescein angiography (FFA), and changes of CNV in FFA were recorded. Multi-factor regression analysis of visual acuity within 1 month and 3 months after PDT was performed with SPSS statistics software. Results The distant visual acuity within 1 month postoperatively was related to the preoperative distant visual acuity, the area of CNV and the changes in the FFA(P=0.000,0.030,0.062), and 3 months after PDT, it was related to the distant and near visual acuity preoperatively and the changes in the FFA(P=0.000,0.054,0.034). The condition of distant visual acuity within 1 month postoperatively was related to the FFA type of CNV and the disease course(P =0.018,0.08). Conclusion The smaller the area of CNV is, the better postoperative distant visual acuity would be. The proportion of improvement of visual acuity is relatively higher in patients with classic CNV. Early treatment for the patients with the indicatio may improve the visual acuity effectively.

Objective To investigate the feasibility of labeling iris pigment epithelial(IPE)cells of rabbits with 5-(and 6-)carboxyfluorescein diacetate succinimidyl ester(CFSE). Methods Enzyme-assisted microdissection was used to isolate the cultured rabbit′s IPE cells.The third or forth subcultured IPE cells were incubated with 2.5,5,10,20,and 40 ?mol/L of CFSE for 1,5,and10min respectively.The fluorescence intensity was detected by flow cytometry,and the leakage of CFSE and its dyeing were observed by fluorescence antibody labeling. Results Incubation with 20 ?mol/L CFSE under 37℃for1minute was the most optimal condition for IPE cells labeling.The coloration of IPE cells stained by CFSE lasted 4 weeks.There was no leakage of dye from labeled rabbit IPE cells to non-labeled human IPE cells in mixed culture process. Conclusion With the advantages of high rate of dyeing,long time of tracing,safety and convenience,CFSE can be used as a new method to label the rabbit′s IPE cells.

ObjectiveTo investigate the possible relationship between choroidal neovascularization (CNV) and macular choroidal watershed zones (CWZ) in patients with age-related macular degeneration (AMD). MethodsFifty-seven selected indocyanine green video angiograms (ICGA) of 57 patients (57 eyes) with AMD were evaluated, and 35 ones of the healthy fellow eyes of 35 patients with unilateral non-AMD fundus diseases were selected as age-matched control. The video angiograms were evaluated for investigating the relationship between CNV and macular CWZ. ResultsIn 57 eyes with AMD, 35 (61.4%) had macular CWZ, while in 35 control patients only 3 (8.57% ) had. The difference was significant (P

Objective To evaluate effects of neoadjuvant chemotherapy on axillary lymph node status in patients with breast cancer.Methods A total of 45 patients with stage Ⅱ or Ⅲ breast cancer treated with neoadjuvant chemotherapy followed by surgery(Combination Group) were compared with 79 patients with breast cancer treated with initial surgery only(Surgery Group) in respect of axillary lymph node status,including the total number of the lymph nodes and the number of positive and negative lymph nodes,according to findings of physical examination,B-ultrasonography,and molybdenum target radiography.Results The total number of the lymph nodes and the number of positive lymph nodes were significantly less in the Combination Group(16.9?5.9 and 2.5?2.2) than in the Surgery Group(20.8?8.0 and 3.9?3.0)(t=-2.856,P=0.005;t=2.790,P=0.006),whereas the number of negative lymph nodes were 14.4?5.4 and 16.7?7.0 in the Combination Group and the Surgery Group,respectively,without statistical significance(t=-1.904,P=0.055).Four patients were found loco-regional relapse in each group during follow-up checkups for 6~19 months(mean,10 months) in 40 patients in the Combination Group and 7~21 months(mean,12 months) in 67 patients in the Surgery Group.Conclusions Total and positive axillary lymph nodes retrieved after axillary lymph node dissection decrease in number after neoadjuvant chemotherapy.

Objective To study the relationships between cognitive impairment in patients with lacunar infarcts and quantitative CT measures and to determine the independent correlative factors of cognitive impairment. Methods Neuropsychological examination was conducted for 128 patients with acute lacunar infarct. Number, location, and volume of infarcts, cerebral atrophy index and severity of white matter lesions (WMLs) were measured and recorded. Results The number of lacunar infarcts in cognitive impairment (CI) group was significantly larger than that in cognitive normal (CN) group. Mean width of sulcus and sylvian fissure, index of frontal horn and ventricular-brain ratio (VBR) were significantly different in both groups. There were more patients with 3 grades or 4 grades WMLs in CI group (62%) than those in CN group (22%). The total volume of lacunar infarcts showed no statistically significant difference. Logistic regression analysis indicated that the number of lacunar infarcts in frontal subcortex and thalamus, the volume of infarcts in anterior periventricular white matter, width of cerebral sulcus and sylvian fissure were correlated with cognitive impairment respectively. Additionally, age and education were correlative factors of cognitive impairment in patients with lacunar infarct. Conclusion Correlative factors of cognitive impairment in patients with lacunar infarct are not merely one feature, but a combination of infarct features (number, location, and volume), cortical atrophy and host factors (age and education).

Objective To detect the combining capacity of peripheral blood NF-E2-related factor 2 (Nrf2)of arsenic-exposed residents in the coal-contaminated arsenism area in Guizhou with the sequence of downstream antioxidant response element (ARE) as well as antioxidase gene expression,and to provide a basis for in-depth revelation of arsenic oxidative damage mechanism to human body.Methods Jiaole and Changqing villages in coal-burning-borne arsenism areas in Xingren County of Guizhou were selected as the survey spots,and 161 cases of arsenic-exposed residents were selected as the arsenic exposed group on the basis of physical examination.They were divided into non-patient group (21 cases) and patient group (140 cases) according to the Diagnostic Criteria of Endemic Arsenism (WS/T 211-2001),and the patient group was further divided into mild hepatosis group (52 cases),moderately severe hepatosis group (36 cases) and non-apparent hepatosis group (52 cases) according to the Diagnostic Criteria of Occupational Chronic (GBZ 59-2010).Moreover,45 residents from one village neighboring to non-epidemic area were selected as controls.The hemocyte nucleoprotein was extracted from peripheral blood in the sampling subjects.The combining capacity of peripheral blood Nrf2-ARE was tested by electrophoretic mobility shift assay (EMSA),and the relative expression quantity of Cu/Zn superoxide dismutase (Cu/Zn-SOD) and glutathione peroxidase 1 (GSH-Pxl) mRNA was tested with real-time fluorescence quantification PCR (qPCR).Results The testing results of Nrf2-ARE combining capacity showed that the difference of Nrf2-ARE combining capacity between groups was statistically significant (F =116.033,P ＜ 0.05).Compared with the control group (3.14 ± 1.34),the Nrf2-ARE combining capacity was higher in the non-apparent hepatosis group (5.17 ± 2.06),mild hepatosis group (13.13 ± 4.84) and moderately severe hepatosis group (32.35 ± 14.76,all P ＜ 0.05);compared with the non-patient group (5.15 ± 3.23) and non-apparent hepatosis group,the Nrf2-ARE combining capacity of mild hepatosis group and moderately severe hepatosis group was higher (all P ＜ 0.05);compared with mild hepatosis group,the Nrf2-ARE combining capacity of moderately severe hepatosis group was higher (P ＜ 0.05).The results of Cu/Zn-SOD and GSH-Pxl mRNA expression showed the relative expression quantities of Cu/Zn-SOD [Median (M):1.127 8,1.257 8,1.632 0] and GSH-Pxl (M:1.334 5,1.940 9,2.062 6) mRNA of non-apparent hepatosis,mild hepatosis,moderately severe hepatosis groups were higher than those of the control groups (M:0.961 8,0.884 3),respectively,and their differences were statistically significant (x2 =13.065,19.934,all P ＜ 0.05).The relative expression quantities of GSH-Pxl mRNA of mild hepatosis group and moderately severe hepatosis group were higher than that of the non-patient group (M:1.248 4),and their differences were statistically significant (all P ＜ 0.05).The correlation analysis indicated the Nrf2-ARE combining capacity was positively related to the Cu/Zn-SOD and GSH-Px1 mRNA expression (r =0.271,0.292,all P ＜ 0.01).Conclusion The increase of Nrtf2-ARE combining capacity by arsenic participates is involved in the regulation of Nrf2 downstream antioxidase gene expression,and this process possibly participates in occurrence and development of coal-burning-borne arsenism and hepatic injury.
