AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation.
METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics.
RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05).
CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.

BACKGROUND:Engineered hepatic tissue is considered a promising strategy for healing acute liver failure. But, there are series of hindrances in the construction of engineered hepatic tissues, including acquisition of vital hepatocytes, choice of scaffolds and culture system, and nutrition supply. OBJECTIVE:To construct three kinds of engineered hepatic tissues in hope to screen the optimal one for transplantation in acute liver failure. METHODS:After purification, amplification, bone marrow mesenchymal stem cells were induced to differentiate into hepatocyte-like cells which were co-cultured with acellular amniotic membrane, DACRON PATCH cardiovascular surgical patch, biological surgical patch, respectively to construct three kinds of engineered hepatic tissues. After 3 days of culture, morphological and functional detections were performed. RESULTS AND CONCLUSION:Rat bone marrow mesenchymal stem cells with higher purity were successful y harvested by using density gradient centrifugation and adherent methods, and then the cells were differentiated into hepatocyte-like cells. In the three kinds of engineered hepatic tissues, hepatocyte-like cells were found to be combined with the biological surgical patch to the maximum extent, and their combination exhibited stronger ability of urea synthesis and albumin secretion, which provides experimental basis for treatment of acute liver failure.

Objective To analyze the relationship between serum intermedin ( IMD ) , CystatinC ( CysC ) and fibro-blast growth factor23(FGF23) with hypertensive left ventricular hypertrophy (HLVH). Methods Serum IMD,Cy-sC and FGF23 levels of 30 patients with essential hypertension(EH group),30 hypertensions with LVH(HLVH group)and 30 healthy subjects(control group)were detected by enzyme-linked immunosorbent assay(ELISA). All the subjects did UCG for LVMI. Results LVMI and serum IMD,CysC,FGF23 levels were significantly higher in EH group than in control(P<0. 05),higher in HLVH group than in EH and control groups(P<0. 05). In the pa-tients with hypertension LVMI and serum IMD,CysC,FGF23 levels were increasing with increased blood pressure levels. LVMI level was positively correlated with serum IMD,CysC and FGF23 levels(r=0. 769,0. 517,0. 700;P<0. 01). Line to LVMI level as the dependent variable,multiple stepwise regression analysis showed that:systolic blood pressure( SBP) ,IMD,CysC,homocysteine( Hcy) ,FGF23 entered regression equation. They were independent risk factors for LVMI. Conclusion Serum IMD, CysC and FGF23 levels are closely associated with EH and HLVH. They may participate in the development of EH and affect the process of HLVH. Combined-detection of ser-um IMD,CysC and FGF23 can be used as a reference index for the condition and prognosis of HLVH.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.
