Glaucoma is the second leading cause of blindness worldwide.It is mainly caused by glaucomatous optic neuropathy characterized by retinal ganglion cells (RGCs) loss,which leads to visual field loss and blindness.There are many risk factors other than intraocular pressure (IOP) elevation are thought to be responsible for RGCs damage induced by glaucoma,such as neurotrophic factors deprivation,excitotoxicity,oxidative stress and enhanced microglia activity,and these factors are essential for glaucomatous optic neuropathy,especially in normal tension glaucoma (NTG).Up to date,the major attempt of glaucoma therapy is to protect optic nerve function by lowering IOP through surgery and drugs.However,the therapies can not arrest RGCs damage although effectively lowing IOP in a number of patients.Novel study is turning to find and develop some new approaches to solve neuroprotection problem targeting to the pathogenic factors of glaucomatous optic neuropathy out of IOP.This review paper mainly focused on the neuroprotective therapies that are developed in the past few years.

METHODS: 60 patients with RAU were treated by locally spraying compound bFGF preparations composing of calculated quantity of bFGF, tinidazole and dicaine on the surface of ulcerations,?other?40?patients?were?treated?by?alternatively smearing Xi Leisan and Smecta on the surface of ulcerations as routine treatment group, tid, for 5 d. RESULTS: The improvement of three indexes including the size, the degree of ache and hyperemia of the ulcerations are greater in compound bFGF treatment group than those in routine treatment group (P

Objective To investigate the relationship of the C-reactive protein (CRP) and metabolic syndrome.Methods The serum level of CRP was determined in 48 cases of obese children and 36 cases of healthy individuals.All children were 10 years old.The differences between the two groups and whether CRP was associated with metabolic syndrome were analyzed.Results The obese children had significant higher serum insulin,TG,TC,CRP,BMI,SBP and HOMA-IR [for respectively (16.1 ± 3.7) mU/L,(1.38 ± 0.29) mmol/L,(4.79 ± 0.88) mmol/L,(1.83 ± 0.89) mg/L,(28.7 ± 5.3) kg/m2,(129.4-11.3) mmHg,(3.81 ± 0.92)] than those of the normal controls [for respectively(10.4 ±2.8) mU/L,(0.75 ±0.12) mmol/L,(4.12 ± 0.65) mmol/L,(0.78 ± 0.22) mg/L,(22.4 ± 3.9)kg/m2,(117.2 ±8.9) mnHg,(2.37 ±0.78)] (t =7.727,12.260,3.846,6.912,6.012,5.349,7.568,all P ＜0.05).The results of correlation analysis showed that CRP had a positive correlation with serum insulin,TG,BMI,SBP and HOMA-IR (r=0.693,0.293,0.525,0.212,0.195,all P＜0.05),but not TC.Conclusion There are significant increases of serum CRP level in obese children,and the increased CRP was closely related with metabolic syndrome.

Objective To explore the role of growth hormone (GH),leptin (Lep),T3,T4,TSH in cord blood in intrauterine growth.Methods 120 healthy newborns (60 males,60 females) were enrolled in this study.The neonates were divided into AGA,LGA and SGA groups according to the relationship between birth weight and gestation.The head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight,the levels of GH,Lep,T3,T4,TSH in the cord blood were measured.Results There were significantly statistical differ ences in growth indexs (all P ＜ 0.05),the levels of GH and TSH were significantly increased [(21.52 ± 2.13) ng/L vs (15.64 ± 1.28) ng/L ; (8.6 ± 0.67) mIU/L vs (3.34 ± 0.29) mIU/L,t =3.042,4.367,all P ＜ 0.05] and Lep,T3,T4 were significantly decreased in LGA group when compared with the AGA group [(7.53 ±0.81) g/L vs (9.55 ± 1.26) g/L; (1.25 ± 0.42) nmol/L vs (1.48 ± 0.37) nmol/L; (69.45 ± 10.07) nmol/L vs (76.68 ± 8.22) nmol/L; t =1.749,1.905,1.783,all P ＜ 0.05],the level of Lep in LGA group was significantly higer than that in AGA group [(14.61 ±2.05) g/L vs (9.55 ±1.26) g/L,t =3.064,P ＜0.05].And GH,Lep,T3,T4 were positively correlated with head circumference,birth length,birth weight,body mass index,biparietal diameter,and placental weight (all P ＜ 0.05).TSH was negatively correlated with growth indexs.Conclusion The levels of Lep,T3,T4,TSH in cord blood were associated with fetal growth and could be used as indicators of intrauterine growth.

Non-receptor tyrosine kinase c-Abl has been implicated in the regulation of the cell cycle,adhesion, apoptosis and DNA damage responses.Its excessive activation is related with the development of chronic myeloid leukemia, and the relationship between c-Abl and leukemia is in depth and detailed research.In contrast to leukemia, the research between c-Abl and solid tumors is just at the early stage.This paper briefly reviews research progress of the c-Abl in solid tumors.

Diabetic retinopathy (DR) is a common cause of blindness,its occurrence and development are the synergic results of multiple factors.Current studies suggest that inflammation and inflammatory factor has an important role in the pathogenesis of DR.The occurrence and development of DR are closely related with interleukins,intercellular adhesion molecules,hasten factors,tumor necrosis factor,C-reactive protein etc.Mesenchymal stem cells (MSCs) are pluripotent cells derived from the mesoderm and have multiple differentiation potentials,and anti-inflammatory and immunosuppressive function.Recent studies shown that MSCs transplantation can protect damaged retina by inflammatory regulation,which become a new research direction for DR treatment.

BACKGROUND: Magnitude and action ways of flow shear stress are important for the endothelialization of small diameter tissue-engineered vessels (TEV), and the TEV resistance ability to blood flow even decides the destiny of implantation. There are many studies on how to construct the TEV and improve anticoagulant ability of TEV after host cell implantation, but the effects of different flow shear stresses on the TEV endothelialization is rarely reported, which may be helpful for increasing the success rate of TEV implantation. OBJECTIVE: To compare the effects of flow shear stresses in single level or stepwise increased on the endothelialization of small diameter TEV and to optimize the TEV in the aspects of shear stress magnitude and loading method. METHODS: The number, morphology and adhesion ability of endothelial cells on the inner wall of TEV were observed through silver nitrate and F-actin staining. RESULTS AND CONCLUSION: Single-level shear stress at 2.5, 3.0 N/m2 for 2 hours removed almost all the endothelial cells seeded on the inner wall of TEV. In contrast, stepwise increased shear stress from 0.5 N/m2 to 3.0 N/m2 at an increase of 0.2 N/m2/2 hours maintained the integrity and oriented along the flow direction, and could induce stress fibers productionin endothelial cells. These results suggest that the stepwise increased flow shear stress can improve the endothelialization of TEV.
