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 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

【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.

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.

Objective To increase the appreciation of manifestations in autoimmune pancreatitis (AIP) and to decrease misdiagnosis rate by investigating the clinical characteristics of AIP. Methods Clinical data were collected and laboratory ,imaging and histopathology were analyzed from the Chinese PLA General Hospital from 1995 to 2009. Patients with AIP were included in the study. Results Eight patients (male 6, female 2) aged 35-69 (52.4 ±9.4) years were diagnosed as AIP from 2006 to 2009. The main clinical manifestations include intermittent jaundice in 6 cases (6/8), abdominal pain in 5 cases (5/8),weight loss in 4 cases (4/8), and accompanied with other diseases of immune system in 4 cases (4/8).The imaging showed head of pancreas enlargement in 3 cases (3/8) and whole pancreas enlargement in 5 cases (5/8). There is a "banana-peel like" ring around the pancreas and irregular stenosis of pancreatic duct. Massive lymphocytes and plasma cells infiltration and parenchymal fibrosis were shown in pancreatic tissues, bile duct,salivary gland and liver in pathology. Clinical manifestations, laboratory examinations and images in 7 cases (7/8) were improved after treatment with prednisone. Twenty-two of them were misdiagnosed as pancreatic or biliary carcinoma and 21 were performed laparotomy in the period of 1995-2005 ( 23 cases). After 2006, however, the misdiagnosis rate significantly decreased from 95.7% ( 22/23 ) to 0. Conclusions AIP seems to be a systemic autoimmune disease rather than an isolated disorder,markedly overlapping with other autoimmune diseases. Definitive diagnosis can be improved by the detection of immune parameters and pathological examination.
