Background Recent studies have demonstrated that glaucoma progression had great relationship with corneal biomechanical properties.However,there are not enough studies about corneal biomechanical properties in different types of glaucoma.Objective This study was to evaluate the corneal biomechanical properties in chronic primary angle-closure glaucoma (CPACG) and primary open angle glaucoma (POAG).Methods Prospective observational study was adopted.Sixty-eight cases (68 eyes) with CPACG and 69 POAG patients (69 eyes) from Zhongshan Ophthalmic Center were investigated by a novel technique named Corvis-ST which can measure corneal deformation.The Cronbach's αt coefficient and intraclass correlation coefficient (ICC) were used to evaluate the repeatability of the parameters from Corvis-ST.The differences of corneal biomechanical properties between POAG and CPACG were evaluated by independent-samples t test.Multiple regression analysis was used to assess the association between parameters of deformation response and clinical factors.This study protocol was approved by Ethic Committee of Zhongshan Ophthalmic Center and complied with Helsinki Declaration.Written informed consent was obtained from each patient prior to any medical examination.Results There were no statistic differences about age,sex and intraocular pressure (IOP) between CPACG and POAG patients (all at P＞0.05).However,differences existed in the number of anti-glaucoma medications (t =-2.388,P =0.020).Measurements of central corneal thickness (CCT),deformation amplitude (DA),and peak distance (PD) demonstrated excellent repeatability (ICC≥ 0.8).There were no statistic differences about CCT,first applanation time/length/velocity (A1 T,A1 L,A1V),second applanation time/length/velocity (A2T,A2L,A2V),DA between CPACG and POAG patients (all at P＞ 0.05).The highest concavity time was shorter (t =2.920,P =0.005),PD was bigger (t =-2.453,P =0.017),and central curvature radius (CCR) was smaller (t =1.997,P =0.050) in POAG than those in the CPACG patients.DA,A1V,A2T and PD were negatively associated with IOP (r =-0.709,-0.531,-0.645,-0.554;all at P＜0.001).However,A1T and A2V were positively associated with IOP (r=0.744,0.546;both at P＜0.001).And CCR was positively associated with CCT (r =0.181,P =0.039).Conclusions It is useable to evaluate corneal biomechanical properties of glaucoma by Corvis ST.Under the same level of IOP,the corneal concavity of POAG is easier than that of CPACG,which indicates that cornea in POAG patients is more deformable.

Objective To discuss the effect of QGY/CDDP hepatoma lines multi-drug resistance (MDR) reversed by gene transfection of mdr1,mrp-ASODN+ultrasound contrast agent+ultrasound.Methods The QGY/CDDP cells were transfected by mdr1,mrp ASODN+ultrasound contrast agent+ultrasound irradiation respectively and detected of the various indicators:cell adhesion rate,cell sensitivity to cell drug-resistance,the mRNA expression of mdr1 and mrp gene,the expression of P-gp and MRP protein. Results After mdr1-ASODN transfection,the drug sensitivity and expression of P-gp,MRP protein of QGY/CDDP cells were smaller changes(P＞0.05),and the rate of cells adherent and expression of resistance gene mRNA were obvious changes(P＜0.05).After mrp-ASODN transfection,the cells adherent rate,the drug sensitivity,the expression of resistance gene mRNA and P-gp,MRP protein were obvious changes respectively(P＜0.05),the experiment group(group 2')had bigger effects(P＜0.05).Conclusions mdr1. mrp-ASODN+ultrasound contrast agent+ultrasound irradiation could safely partly reverse MDR of hepatoma cells,which is a potential new approach for gene therapy.

Objective To investigate the effect of calpeptin on diaphragmatic injury and atrophy under controlled mechanical ventilation in rats.Methods A total of 24 SPF Sprague-Dawley (SD) rats were randomly divided into anesthetized control group (CON group),24-hour controlled mechanical ventilation group (CMV group),and 24-hour CMV + treatment with calpeptin group (CMVC group),with 8 rats in each group.Animals in the CON group received an intraperitoneal injection of pentobarbital sodium without CMV and continuous infusion of pentobarbital sodium.A small-animal ventilator was used for 24 hours in rats of CMV group.Rats of CMVC were treated with a specific calpain inhibitor calpeptin (4 mg/kg).The drug was injected subcutaneously 2 hours before and 8,15 and 23 hours after mechanical ventilation.Changes in diaphragm ultrastructure,light microscopic picture,and myosin heavy chain (MHC) expression were observed.Results ① Alignment of myofilaments and normal Z-band,and the shape of mitochondria were maintained in CON group as revealed by electron microscope.The signs of misalignment of myofibrils,disruption of Z-band and vacuolar mitochondria were found in CMV group,and they were obviously improved in CMVC group.The density of muscle injury (× 10-2/μm2) in CMV group was significantly higher than that in control group (36.8 ± 13.7 vs.6.4 ± 6.3,t=6.373,P=0.001),and that in CMVC group was significantly lowered (17.6 ± 9.1 vs.36.8 ± 13.7,t=3.694,P=0.002).② In CON group,the diaphragm fibers appeared regular in cross section without pathologic change under light microscopy.Fuzzy muscle striations,irregular muscle fibers,centralized nuclei and swelling of capillary endothelial cells were observed in CMV group,while pathological changes in the CMVC group were milder significantly.③ In CMV group,the density of MHCslow and MHCfast was lower compared with that of CON group,and the gray value was lowered by 61.1％ (t=8.138,P=0.001) and 77.1％ (t=8.844,P=0.001),respectively,especially in MHCfast.However,the gray values of MHCslow and MHCfast were increased by 1.51 folds (t=4.601,P=0.010),and 1.33 folds (t=2.859,P=0.011),respectively,after treatment with calpeptin,and the elevation was more significantly in MHCslow.Conclusions Diaphragmatic injury and atrophy were found after CMV for 24 hour.Calpeptin could reverse the detrimental effects of CMV,and it suggested that calpain plays an important role in modulating the ventilator-induced dysfunction of the diaphragm.

PurposeTo investigate the physical characteristics of the lumbar bone marrow fat content by analyzing the correlation of the lumbar bone marrow fat content with age, gender, body mass index (BMI) and waist circumference. It may be helpful to deepen the understanding the occurrence regularity of osteoporosis. Materials and Methods A total of 144 subjects were recruited including both healthy volunteers and the patients with chronic low back pain. The height, weight and waist circumference were measured, and the body mass index was calculated. All the subjects took spectroscopy sequence at the third lumber vertebra with single-voxel point resolved spectroscopy (PRESS) method. Lipid (1.3 ppm) to water (4.67 ppm) ratio (LWR) and lipid fractions (FF%) were measured. LWR and FF% of L3 were compared among the patients with different gender, age, BMI and waist circumference. The correlation of LWR and FF% of L3 and age were analyzed.Results The LWR and FF% of L3 showed no signiifcant difference between the male and female (t=-0.267 and-0.993,P>0.05). There was statistical difference of LWR and FF% among the different age groups (F=3.723 and 5.478,P<0.05). LWR and FF% of female in 61-70 year-old group showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% of L3 in 20-30 year-old female group showed signiifcant lower than that in >70 year-old group (P<0.05). LWR of L3 for both male and female in 60-70 year-old group also showed signiifcant higher than that in 20-30, 31-40, 41-50 and 51-60 year-old group (P<0.05). FF% for both male and female in 20-30 year-old group showed signiifcant lower than that in 31-40, 41-50, 51-60, 61-70 and>70 year-old group (P<0.05). FF% of 61-70 year-old group was signiifcant different from that in 31-40, 41-50, 51-60 year-old group (P<0.05). The LWR and FF% of L3 showed no signiifcant difference between the different BMI groups and waist circumference groups (P>0.05). Age was positive correlated with FF% of L3 (r=0.321,P<0.05).Conclusion The lumbar bone marrow fat content is correlated with age, but is not correlated with gender, BMI and waist circumference.
