●METHODS: Totally 195 patients with severe bacterial keratitis and conjunctivitis were included in this study. Based on the sequence of enrollment, they were randomly divided into three groups: group A ( 65 patients) received levofloxacin, group B ( 65 patients) received suture method under microscope, group C received suture method with loupe besides the same basic operative treatment in the two groups. The curative effect and drug tolerance were observed and compared statistically.
●RESULTS: ln group A, 54 cases were cured, in the rate of 83. 1%, 7 cases ( 10. 8%) were excellent, 3 cases (4. 6%) were valid, 1 case (1. 5%) was invalid. ln group B, 25 cases (38. 5%) were cured, 6 cases (9. 2%) were excellent, 23 cases (35. 4%) were valid, 11 cases (16. 9%) were invalid. ln group C, 4 cases (6. 2%) were cured, 3 cases (4. 6%) were excellent, 36 cases (55. 4%) were valid, 22 cases (33. 8%) were invalid. The curative effect and drug tolerance among groups had obvious differences (P<0. 05).
●CONCLUSlON: Levofloxaoin is effective and safe for the treatment of bacterial conjunctivitis and keratitis, which is not resistant and worthy of promotion.

Epidermal growth factor (EGF) is a very important peptide growth factor,which is not only involving in a variety of ocular cell mitosis,proliferation and differentiation,but also participates in mediating the signal transduction between cell and cell,cell and matrix interaction and other biological functions.Corneal injury is a common and frequently occurring disease in ophthalmology,and it would lead to blindness without appropriate treatment.Researches showed that EGF can promote the repair and regeneration of wounded cornea.In recent years,these studies advance from animal experiment stage to clinical stage and also from the morphology evaluation stage to the genetics study stage.This paper provided an overview of EGF concept,its biological effectiveness,its relationship to corneal injury and its clinical application.

Epigenetics refers to the changes of heritable gene expression without modification of DNA sequences which is one of major research interest of human genome study post gene era. Epigenetics may play an important role in the pathogenesis of retinal diseases. Epigenetics modification in the regulation of gene expression and function mainly includes DNA methylation,histone acetylation and non-coding RNA such as miRNA. The implication of epigenetics has been suggested with the pathogenesis of retinal fibrosis, retinitis pigmentosa, age-related macular degeneration and diabetic retinopathy. In addition, the epigenetics drug has potential to be used in the treatment of retinal diseases.

?AIM: To explore the application of 25G vitreous cavity perfusion in phacoemulsification for cataract after vitrectomy.?METHODS:Forty-eight patients (50 eyes) with cataract after pars planavitrectomy in our hospital from September 2013 to September 2014 were selected to receive phacoemulsification and implantation of artificial lens with 25G vitreous cavity perfusion. Best corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , postoperative discomfort, healing of scleral puncture and postoperative complications were observed.?RESULTS: All patients underwent surgery successfully. Compared to before operation, there was less patients with BCVA ≤0. 1, more patients with BCVA 0. 3-0. 5,>0. 5,>0. 3 (P<0. 05). The visual acuity of 1 eye decreased because of vitreous hemorrhage caused by original fundus lesion recurrence. The mean IOP before operation and at 1, 7d, 6mo after operation were 14. 67±0. 62mmHg, 14.75±0.56mmHg, 14.86±0.58mmHg, 14.88±0.59mmHg, respectively. There were no statistically significant differences of IOP between that before operation and those at 1, 7d, 6mo after operation (P>0. 05). No obvious eye discomfort and severe complications after operation were observed.? CONCLUSION: The effect of 25G vitreous cavity perfusion in phacoemulsification for cataract after vitrectomy is good and it can maintain IOP, keep anterior chamber stable and decrease the complications risk.

Objective To investigate the correlation between NT‐proBNP ,hs‐CRP level ,echocardiography and early avascu‐lar necrosis of coronary artery syndrome (ACS) ,coronary artery lesion degree .Methods 142 patients admitted in this hospital for chest pain from March 2013 to February 2014 were enrolled ,and all patients′history ,electrocardiogram (ECG) ,plasma levels of N‐terminal pro‐Brain Natriuretic Peptide (NT‐proBNP) ,hypersensitive C‐reative protein (hs‐CRP) and cTnT were recorded or tested within 24 hours ,while left ventricular ejection fraction (LVEF) and left ventricular end‐diastolic diameter (LVEDd) were recorded by echocardiography .According to the history and coronary angiography results conducted during hospitalization ,patients were di‐vided into acute ST segment elevation myocardial infarction (STEMI) group ,acute non‐ST segment elevation myocardial infarction (NSTEMI) group ,unstable angina pectoris (UA) group and control group (normal coronary angiography ,cTnT and ECG) .Pa‐tients with abnormal coronary angiography results were further divided into single vessel lesion group ,double vessel lesion group and triple vessel lesion group .The differences of plasma NT‐proBNP level ,hs‐CRP level and LVEF in each group ,and multivariate linear regression analysis were conducted to find out the independent risk factors for elevated plasma NT‐proBNP .Results 102 ACS patients and 40 normal patients were enrolled .Plasma levels of NT‐proBNP ,hs‐CRP and LVEF in NSTEMI group (n=30) and STEMI group (n=32) were significant different from UA group (n=40) and control group (n=40) respectively (P<0 .05) . The NT‐proBNP levels in control group and triple vessel lesion group (n=41) were respectively significant different from both sin‐gle vessel lesion group (n=30) and double vessel lesion group (n=31) (P<0 .05) .Multivariate linear regression analysis showed that ,plasma hs‐CRP level (P=0 .007) ,coronary artery lesion degree (P=0 .00) and history of diabetes (P=0 .006) were positive associated factors of NT‐proBNP level ,while LVEF was the negative associated factors of NT‐proBNP level(P=0 .036) .Conclusion Plasma NT‐proBNP level ,hs‐CRP level and LVEF are closely related to ACS ,and they might play an important role in determi‐ning the extent of early ischemic necrosis and clinical classification .Plasma NT‐proBNP level could be an important molecular mark‐er to reflect the degree of coronary artery lesion .

Objective To investigate the diagnosis and therapy of Crohn's disease(CD).Methods The clinical data of 30 cases of pathologically proven CD from 1992 to 2005 were analyzed,26 cases were followed up.Results Among the 30 patients with CD,13(43.3%)diagmosed by endoscopy and biopsy.and17 cases(57.7%)were diagnosed by operation and pathology Before operation,6 cases were diagnosed as acute abdomen,4 cases as ileus,3 cases as massive hemorrhage of gastrointestinal tract,2 cases as colorectal cancer,1 case as intestinal fistula and 1 case as head mass of pancreas.Of the 26 cases followed up cases,15 cases accepted operation with 5 cases of recurrence;21 cases have taken drugs,and the total effective rate was 73.1%.Conclusions CD is a chronic relapsing disease and is difficult to diagnose.The majority of patients undergo operation due to misdiagnosis or complications.CD is prone to relapse postoperatively,quality of life is poor,and one must heighten awareness of these patients,make early diagnosis,directed therapy,and intensify follow up.
