AlM: To investigate the risk factors of diabetic retinopathy ( DR) in type 2 diabetes patients.METHODS:A total of 380 cases of type 2 diabetes were selected from January 2014 to June 2014, divided into DR group (126 cases) and non-diabetic retinopathy ( NDR) as control group (254 cases), all patients were underwent medical history, physical examinations, laboratory and assistance examinations. The prevalence and single factor and multiple factors of DR were analysed by the logistic regression model.RESULTS: The univariate logistic regression analysis showed that DR was associated with diabetes duration, systolic blood pressure, triglyceride, total cholesterol, low - density lipoprotein, urine protein, intraocular pressure, carotid intima - media thickness, peripheral neuropathy disease was the related risk factors for DR. ln multiple logistic regression analysis, only duration was the related risk factors for DR.CONCLUSlON:The occurrence of DR is the outcome of combined action of multiple factors, duration is an independent risk factor for occurrence of DR.

【Objective】 To examine the regeneration of NPY-immuno reactivity (IR) retinal ganglion cells (RGCs) and the effects of cholera toxin ( CTx) injected or/and peripheral nerve implanted on regeneration of NPY-IR RGCs. 【Methods】 16 adult golden hamsters were ramdomly divided into 4 groups. Optic nerve (ON) was transacted and a segment of autologous sciatic nerve (attached g raft, AG) was removed and sutured to the proximal stump of ON in regenerating co ntrol group (AG group). The animals in experimental groups were further treated with CTx injection or/and implantation of a short of segment sciatic nerve (SN) intravitrously. By using the retrograde labeling with fluorogold (FG) combined w ith fluorescent immunocytochemistry, the regenerated NPY-IR RGCs were observed and counted under fluorescent microscope. 【Results】 At 4 weeks after surgery, the mean number of regenerated NPY-IR RGCs per retina in AG group was 58±22 wh ich constitutes (3.36±0.65)% of the total regenerated RGCs. In AG+CTx, AG+SN and AG+CTx+SN experimental groups, the mean numbers of regenerated NPY-IR RGCs per retina were 143±47, 125±37 and 437±77 ordinally which constitute (5.15± 0.89)%, (5.34±0.37)% and (8.11±0.85)% of the total regenerated RGCs respec tively, which were increased significantly compared with those in AG group. 【Co nclusion】 The results show that the axotomized NPY-IR RGCs have th e capability of regenerating their axons into the attached PN graft, CTx and/or SN could enhance the regeneration of the NPY-IR RGCs.

Objective The present study was aimed at investigating the effects of cholera toxin(CTx) on promoting the regeneration of retinal ganglion cells(RGCs) in hamster retina. Methods After optic nerve (ON) transection, an autologus sciatic nerve (attached graft, AG) was removed and sutured to the proximal stump of the ON. CT X was injected or (and) a small segment of sciatic nerve (SN) inserted intravitrously. Animals were separated into 5 groups:regenerating control group(AG groups and solution groups); AG+CT X groups; AG+SN groups; AG+CT X+SN groups; Effect and Dosage groups; Animals in the former 4 groups were allowed to survive for 2-6 weeks respectively. The regenerated RGCs were labeled retrogradely by granular blue, and the changes in number of regenerating RGCs in each retina were observed under fluorescent microscope. Results The mean numbers of regenerating RGCs in AG+CT X groups were increased and significantly higher than those in AG groups and solution groups at each time point( P

AIM: To explore the main risk factors related to the incidence of endophthalmitis in patients after cataract surgery in China and to provide evidence for prevention.METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.
RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time ( ≥ 10min ), common operating room and control of using time of topical anesthetic were 1. 81(95% CI: 1. 43-1. 69),3. 66 (95% CI: 1. 64 - 8. 16),2. 21 (95% CI: 1. 46 -3. 32),3. 54 (95% CI: 2. 47 - 5. 06),2. 77 (95% CI: 2. 07 -3. 72),2. 09(95% CI: 1. 53-2. 86).
CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.

Gastrointestinal stromal tumor(GIST) is the most common mesenchymal malignancy of the GI tract. The mainstay of treatment is surgery. For patients in whom complete resection is not possible, or in patients with metastatic or recurrent disease, they are unresponsive to standard chemotherapy and to radiotherapy. There has been no effective systemic treatment for unresectable GIST or metastatic disease. Gain-of-function mutations of the KIT proto-oncogene occur in up to 90% of GIST, allowing constitutive activation of tyrosine kinase (i.e. auto-phosphorylation of tyrosine residues independent of ligand-receptor binding), leading to aberrant cell division and tumour growth. Imatinib selectively inhibits the tyrosine kinase activity associated with KIT, which forms the rationale for evaluating its effects in GIST. Herein, we review recent developments in treatment for GIST and implication for optimal treatment in these patients.

Tumor recurrence and metastasis are the major cause for cancer patient death. Aberrant glycosylation is one of the important mechanisms of malignant tumor metastasis. The glycoprotein CD24, which could be a ligand for P-selectin on the surface of activated endothelial cells and platelets, appears to be a new diagnostic marker of tumors and possibly participates in tumor metastasis with unknown pathway. ?1,3 Fucosyltransferase Ⅶ (FucT-Ⅶ) is one of the fucosyltransferases which catalyze the transfer of a fucosyl residue from GDP-?-L-fucose to a sugar acceptor, usually galactose in the sugar chains of glycoproteins or glycolipids. The elevated expression of sialyl Lewis (SLeX), the only carbohydrate product of ?1,3 FucT-Ⅶ , predicts an ominous prognosis and high risk of recurrence and regulates the function of CD24. It is possible that ?1,3 FucT-Ⅶ may enhance the glycosylation of CD24 and thus promote the tumor metastasis.
