AIM:To observed the variation regularity of corneal endothelial cells in patients with different diabetes duration after phacoemulsification, and investigate the effects of diabetes and its disease duration on corneal endothelial cells.
METHODS: Ninety-seven ( 135 eyes ) cataract patients with diabetes were selected randomly and divided into GroupⅠ( which diabetes duration ≥10a) and GroupII(which diabetes duration <10a) according to their disease duration. Additionally 62 (89 eyes) age-related cataract patients were randomly selected as the control group. The corneal endothelial cell density ( CD ) , proportion of hexagonal cell and coefficient of variation ( CV ) in the three group patients were measured respectively before phacoemulsification and after surgery. And the measurement results were statistically analyzed.
RESULTS:The corneal endothelial CD and proportion of hexagonal cell in the three group were decreased after surgery compared with preoperative. But the CV of corneal endothelial cells was increased on the 1 st wk and in 1st mo after surgery compared with the preoperative. The difference was statistically significant (P<0. 05). The corneal endothelial CD and proportion of hexagonal cell in the two diabetic groups were lower than the control group after surgery. However, the CV of corneal endothelial cells was higher than the control group. The difference was statistically significant ( P < 0.05 ) . There was no significant difference in the corneal endothelial CD, proportion of hexagonal cell and CV between the two diabetic groups before phacoemulsification (P>0. 05). The proportion of hexagonal cell in Group Ⅰ was lower than which in GroupIIafter surgery. While the CV was higher than which in Group II. The difference was statistically significant (P<0. 05).
CONCLUSION: Phacoemulsification has some damage on the corneal endothelial. Since the impact of diabetes on the morphology and function of corneal endothelial cell was related to the diabetic duration. So phacoemulsification has more obvious damage on the corneal endothelial in diabetic patients. And the diabetic duration was longer, the damage on the corneal endothelial in phacoemulsification was more easily.

In the presence of ZnO nanoparticles ( ZnO NPs ) and EDTA, luminol could produce strong chemiluminescence ( CL) without any oxidant. Therefore, a new CL system was established based on luminol-EDTA-ZnO NPs. As caffeic acid could strongly inhibit the CL, a flow injection CL method for the determination of caffeic acid was proposed. Under the optimized conditions, the relative CL intensity was linear over the logarithm of concentration of caffeic acid ranging from 1 . 0í10-7 mol/L to 1 . 0í10-5 mol/L with the detection limit of 1. 8í10-8 mol/L (3σ). The relative standard deviation (RSD) for the determination of 4 . 0í10-7 mol/L caffeic acid was 3 . 5% ( n=11 ) . The new method was successfully applied to determine the caffeic acid content in the tablets with the recoveries in the range of 97%-101%.

Objective To study the expression of human kallikrein gene(KLK) 4 and KLK5 in ovarian cancers,and to investigate the pathogenesis in malignant tumors. Methods Fifty specimens of ovarian cancers were divided into three groups: malignant tumor group(n=23),borderline tumor group(n=6) and control group(normal or benign tumor,n=21).Fluorescent quantitative RT-PCR was employed to determine the expression of KLK4 and KLK5 in these specimens. Results The expression of KLK4 in ovarian cancers was significantly higher than that of the control group(P

BACKGROUND: It has reported that the combination of Tacrolimus and Wuzhi capsules can increase the peak concentration and area under curve of Tacrolimus recipients, however, the effects of this combination on recipients is poorly understood. OBJECTIVE: To investigate the effects of Wuzhicapsules on the blood concentration of Tacrolimus recipients. METHODS: A total of 38 renal transplantation recipients receiving triple therapy regime (Tacrolimus+mycophenolate +Prednisolone) were involved in the study and were divided into the experimental group (n=21) and control group (n=17). Recipients in the experimental group were taking Wuzhi capsules simultaneously, and those in the control group were not taking Wuzhicapsules. The Tacrolimus dosage to therapeutic concentration window and renal function were compared between the two groups at months 1,3 and 6 after transplantation. The incidence rates of acute rejection and diabetes mellitus, and renal and liver functions were observed at 6 months after transplantation. RESULTS AND CONCLUSION: The Tacrolimus dosage to therapeutic concentration window of the experimental group was significantly smaller than that of the control group (P < 0.05). However, incidence rate of acute rejection, diabetes mellitus, and renal and liver functions had no dramatically difference in 2 groups (P > 0.05). Results suggest that Wuzhi capsules may improve the immunosuppressive efficacy of Tacrolimus in renal recipients, therefore, can decrease the toxic effect of Tacrolimus with reduction dosage.

Objective To study the effects of Wortmannin, inhibitor of PI3K and SB202190, inhibitor of P38 MAPK and PD98059, inhibitor of ERK1/2 on the migration of epidermal growth factor (EGF)-induced vascular smooth muscle cells (VSMCs). Methods There were fives groups in this experiment, including control group, EGF group, PD98059 (PD) group, SB202190(SB) group and Wortnannin (WT) group. The migration rate of the VSMCs was measured by wound healing assay. Results At the 24th hours after wounding, there was obvious migration in EGF group compared to control group. The migration of VSMCs was significantly inhibited in PD group, SB group and WT group compared to the EGF group, but there were no significant difference among three inhibitor groups. At the 30th hours after woun-ding, there was still obvious migration in EGF group compared to control group. The migration of VSMCs was significantly inhibited in the three iuhibitors group compared to the EGF group, and there were significant difference among three inhibitor groups. Furthermore, inhibiting effect on VSMCs in SB group was more obvious compared to PD group and WT group. Conclusion These results suggested that the migra-tion of EGF-induced VSMCs may play a role through PI3K, P38 MAPK and ERKI/2 signal pathways, and the effect of P38 MAPK signal pathway is very important.
