Retinal ischemia is a common cause of blindness and visual impairment.Some eye diseases,such as glaucoma,retinal artery occlusion and diabetic retinopathy,are associated with retinal ischemia.It is very important to build an ideal animal model which can imitate human retinal ischemia disease for investigating the pathological mechanism and treatment of retinal ischemia.Rodent is a popular choice for retinal ischemia model due to its availability and the similarity to human retinal blood supply.To provide a supportive evidence of retinal ischemia research,some literature concerning rodent models is reviewed and various methods to build the model are summarized,such as elevated intraocular pressure,optic nerve ligation,ligation of vessels,photo-chemistry,endothelin-1 injection and middle cerebral artery occlusion intraluminal suture,etc.Here,the specific protocols,the pathological changes and molecular mechanism of each model are reviewed.

Objective To evaluate the colon cleaning efficacy and safety of prucalopride combined with polyethylene glycol electrollytes powder in bowel preparation for colonoscopy examination and treatment under colonoscopy in elderly patients.Methods Elderly patients who prepared for colonoscopy were enrolled from October 2014 to January 2015.They were divided into group A,B and C.Patients of group A only took polyethylene glycol electrolyte powder (137.12 g dissolved in 2 000 mL warm water,stired until completely dissolved),patients of group B took polyethylene glycol electrolyte powder (same usage as group A) combined with prucalopride 2 mg/d for one day,patients of group C took polyethylene glycol electrolyte powder (same usage as group A) combined with prucalopride 2 mg/d for three days.The bowel preparation effects,especially ascending colon and ileocecal junction and cardiovascular adverse effects in all the patients and constipation patients of three groups were compared.Student t test,chisquare test and analysis of variance were performed for statistical analysis.Results A total of 124 elderly patients were divided into group A (64 cases),group B (23 cases) and group C (37 cases).Bowel preparation scores of total colon and ascending colon-ileocecal junction of group A,B,C were 8.34±0.90 and 2.56±0.56,8.96±0.21 and 2.96±0.21,8.86±0.35 and 2.86±0.35,respectively.The cleaning effects in total colon and ascending colon-ileocecal junction of group B were better than those of group A (t=5.52 and 5.15,both P＜0.05).The cleaning effects in total colon and ascending colon-ileocecal junction of groupCwere better than those of group A (t=4.69,3.65,both P＜0.05).There was no statistically significant difference between group B and group C in cleaning effects in total colon and ascending colon-ileocecal junction (both P＞0.05).There were 33,11 and 29 constipation cases in group A,B and C,respectively.The bowel preparation scores for total colon and ascending colon and ileocecal junction of group A,B,C were 7.85±0.94 and 2.24±0.56,8.91±0.30 and 2.91±0.30,8.83±0.38 and 2.83 ± 0.38,respectively.The cleaning effects in total colon and ascending colon-ileocecal junction of group B were better than those of group A (t=6.72 and 5.49,both P＜0.05).The cleaning effects in total colon and ascending colon-ileocecal junction of group C were better than those of group A (t=104.04 and 59.65,both P＜0.05).There was no significant difference between group B and group C in cleaning effects in total colon and ascending colon ileocecal junction (both P＞ 0.05).No obvious cardiovascular adverse events were observed in the patients of three groups.Conclusions The cleaning effects of prucalopride combined with polyethylene glycol electrolytes powder are good for colonoscopy examination in elderly patients,including elderly patients with constipation,especially in ascending colon and ilecocecal junction.No obvious cardiovascular adverse events are observed.

Objective To investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P
