?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

ObjectiveTo investigate the effects and mechanism of rosuvastatin on the expression of tissue factor in cultured human monocyte-macrophages cells which was induced by oxidized low density lipoprotein(ox-LDL).MethodsThe human monocyte-macrophages cells were divided into four groups:control group,ox-LDL group,Poly-inosine monophosphate (Poly Ⅰ) group,rosuvastatin group.The expression of LOX-1mRNA and TF mRNA was assayed by RT-PCR.The ELISA was performed to determine the protein concentration of TF.ResultsCompared with control group,the expression of LOX-1 mRNA and TF mRNA was increased in the ox-LDL group[ (3.25156±0.15772) vs (1±0) ; (2.522451±0.138967) vs (1±0) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the expression of LOX-1 mRNA in the Poly-inosine monophosphate group and rosuvastatin group,TF mRNA were decreased in the ox-LDL group[ (2.95139±0.157253) vs(3.25156±0.15772) ; (2.877343±0.156558) vs(3.25156±0.15772) ; (1.811956±0.169699) vs (2.522451±0.138967) ; (1.687701±0.174647) vs (2.522451±0.138967)],and it was in a concentration-dependent manner(P＜0.05).Compared with control group,the expression of TF in the ox-LDL group was increased [(207.7233±1.154701) vs (184.8467±0.871799) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the Poly-inosine monophosphate group and rosuvastatin group [(197.8733±1.505003) vs (207.7233±1.154701) ;(202.9567±2.722744)vs(207.7233±1.154701) ],the expression of TF in the ox-LDL group were decreased,and it was in a concentration-dependent manner (P＜0.05).ConclusionsLOX-1 may be responsible for the expression of TF in human monocyte-macrophages cells induced by ox-LDL.Rosuvastatin is able to down-regulate the expression of LOX-1mRNA in human monocyte-macrophages cells through oxLDL,and TF mRNA and TF expression can be reduced.

Objective To analyze the complications, treatments and prognosis of simultaneous pancreas-kidney transplantation. Methods Forty cases of simultaneous pancreas-kidney transplantation performed between Dec. 1999 and Jan. 2010 in our center were retrospectively analyzed. Results Regarding surgical complications, 4 cases had severe hematuria after operation,which needed clinical intervention, including 1 patient receiving catheterization in duodenum to stop bleeding. Two patients were treated with continuous bladder irrigation, and the remaining one received surgical haemostasis because of donor's duodenum and bladder anastomotic artery hemorrhage.Abdominal hemorrhage occurred in 4 patients, including pancreatic hemorrhage in 3 cases and duodenal muscularis hemorrhage in one case. All of them received surgical treatment for hemostasis.Abdominal infection occurred in 8 cases: one died of multiple organ failure, 2 cases were cured after drainage of abscess, 2 cases underwent surgical removal of abscess, and 3 cases were cured after antibiotic therapy. In one case of postoperative anastomotic leakage, pancreas was resected. Four cases of postoperative ileus were cured by continuous clysis with traditional Chinese medicine. Seven cases had pulmonary bacterial infections, including one cases associated with fungal infection. They were cured by the anti-infective treatment. Other complication included poor healing in 5 cases and urinary infection in 2 cases. After combined simultaneous pancreas-kidney transplantation, 10 patients received reoperation because of surgical complications (14 operations). The re-operation rate was 25 %, including 2 patients (4 operations) for hematuria, 4 patients for abdominal hemorrhage, 2 patients (3 operations) for abdominal infection, 1 patient for pancreatic venous thrombosis, 1 patient for anastomotic leakage, and 1 patient for pancreatic fistula. Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with endstage renal disease, surgical complication is still affecting the pancreas and kidney grafts after transplantation.

Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.
