Objective To explore the relationship between blood lipid level and primary open angle glaucoma(POAG)and intraocular pressure(IOP).Methods A retrospective case-control study was designed.80 POAG patients from EYE & ENT hospital of FUDAN university were collected as a case group from January 2015 to May 2016.Meanwhile 80 age and gender matched healthy people were collected as a control group.The differences of gender in men subgroup (POAG:44,Control:39) and female subgroup (POAG:36,Control:41) showed no statistic significance.Serum total cholesterol(TC),total triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),apolipoprotein A(Apo A) and apolipoprotein B(Apo B) were measured using Roche automatic biochemical analyzer.The analysis of the above mentioned lipid levels between POAG group and control group was conducted by independent student′s T test and multivariate logistic regression.The relationship between lipid level and IOP was analysied using Pearson correlation test.Results The TG level was (1.40±0.71)mmol/L in the POAG group,(1.00±0.37)mmol/L in the control group.The difference had statistic significance (t=4.467,P<0.001).The HDL-C level in the POAG group was (1.22±0.36)mmol/L,(1.38±0.25)mmol/L in the control group.The difference also had statistic significance (t=-3.228,P=0.002).Comparison between the men subgroup and female subgroup found that the TG level in the POAG group of men was (1.47±0.71)mmol/L,(1.01±0.36) mmol/L in the control group and the HDL-C level were (1.14±0.31) mmol/L,(1.32±0.20)mmol/L in two groups.Both the level of TG and HDL-C had statistic significance in men (t=3.717,P<0.001;t=-3.240,P=0.002).The TC,TG level in the POAG group and control group of women respectively were (4.59±0.81)mmol/L,(1.33±0.72)mmol/L and (4.21±0.64)mmol/L,(0.99±0.38)mmol/L.Both blood level were significantly higher than the control group in women (t=2.278,P=0.026;t=2.503,P=0.016).Logistic regression analysis showed that the TG level correlated with POAG (P=0.004,OR=2.831,95% CI=1.392-5.759)and both POAG in the men and women (P=0.025,OR=3.223,95% CI=1.156-8.989;P=0.045,OR=2.554,95% CI=1.020-6.395).Pearson test showed that the TG level of POAG patients was positively associated with IOP in spite of gender(P<0.05).Conclusion The peripheral blood level of TG was significantly increased in the POAG patients and significantly correlated with IOP,which indicated that the increased peripheral blood level of TG may be the independent risk factor for the POAG..

Objective A large sample of multi-factor Logistic analysis of clinical biochemical indicators from elderly cataract patients were done to find the characteristics of possible changes in potential factors for cataract-related indicators and explore the pathogenesis of cataract from the perspective of laboratory diagnosis.Methods A retrospective case control study was conducted .Cataract patients from Eye-Ear Nose Throat Hospital of Fudan University were collected during June 2011 to July 2015 and routinely tested for 14 clinical biochemistry indicators including ALB , GLU, TP, GLB, BUN, URCA, Cr, LDH, ALP, Ca, Na, K, Cl, and P.The mean age of the 3 527 cataract patients (1 804 males, 1 723 females) was (64.47 ±11.29) years.Those data were reserved by LIS (Laboratory Information System) system and were retrieved for large data analysis . The control group was filtered from hospitalized patients besides cataract patients during January 2014 to July 2015.The mean age of the 3 333 control subjects ( 1 770 males, 1 563 females ) was ( 64.04 ±9.03 ) years.Biochemical indicators between cataract group and control group were analyzed by independent student′s t-test and Logistic regression .Meanwhile , the objects were divided into 3 groups according to the age (40-59 years,60-79 years,≥80 years) for independent student′s t-test with the control group respectively .Results There are no statistical difference in age ( t=1.663,P=0.096) and gender ( t=2.63,P=0.105 0) between cataract group and control group ( P>0.05).The results of Logistic regression between cataract group and control group were as follow : ALB (OR=1.053,95%CI=1.019-1.088),BUN(OR=1.113,95% CI=1.076-1.152),Cr(OR=1.007, 95%CI=1.003-1.010),GLB(OR=1.049,95% CI=1.018 -1.081),GLU(OR=1.175,95% CI=1.139-1.211),Cl(OR=1.059,1.032 -1.088),Na(OR=1.180,95% CI =1.150 -1.212).Those might be enrolled as risk factors for cataract (P<0.05).The level of ALB, GLU, Na and Cl in cataract group according to different age groups were significantly higher ( t=8.780,t=4.670, t=9.695, t=6.415, P<0.05) than that of control in 40-59 age group;the level of ALB, BUN, Cr, GLU, Na and Cl in cataract group was significantly higher ( t=4.974, t=9.414, t=4.123, t=6.906, t=14.741, t=9.212, P<0.05) than control in 60 -79 age group; the level of BUN, Cr, GLU, Na and Cl in cataract group was significantly higher (t=6.077, t=4.906, t=2.626, t=5.459, t=3.424, P<0.05) than control in 80-age group.Conclusions The level of ALB, BUN, GLB, Cr, GLU, Na and Cl in peripheral blood of cataract patients was significantly increased which suggested that those change might associated with the pathogenesis of cataract .

Objective In order to explore the association between complement C3 and primary open angle glaucoma (POAG),the serum complement C3 level was detected and the polymorphism of the C3 exon gene was analyzed in patients with POAG.Methods A prospective case-control study was designed.A total of 45 patients with POAG visiting Eye &ENT hospital of Fudan University were collected from December 2014 to December 2015,and 45 age-/gender-matched healthy subjects from yearly health screening were collected as normal controls.Serum C3 concentration was detected by immunoturbidimetric assay.Meanwhile,genomic DNA was extracted from peripheral blood leukocytes,and sequencing for C3 exons was followed with PCR to analyze the gene polymorphism.Statistical analysis was performed by use of SPSS 20.0 software.Student's t test was used to evaluate the difference of serum C3 level between two groups.Chisquare test was used to analyze the difference in the distribution of C3 exon gene polymorphism between two groups.The one-way ANOVA was utilized to analyze the difference of serum C3 level among different genotypes of C3 exon.Results The serum level of C3 in POAG (104.81 ± 29.15)mg/dl was significantly lower (t =-3.162,P =0.002) compared to controls (121.06 ± 18.39) mg/dl.There were a total of seven single nucleotide polymorphisms (SNPs) (rs2230201,rs2230204,rs2230205,rs428453,rs423490rs7951,rs539822147) within the C3 exon gene region,but no mutation was detected.There was no difference in the frequency and distribution of these SNPs between POAG and controls,as well as,there was also no significant difference in serum C3 level among these SNPs genotypes.Conclusions Decreased serum C3 level in POAG patients indicated that complement C3 might be involved in the pathomechanism of glaucoma.No significant abnormality of C3 exon gene was detected,so the gene polymorphism having an impact on serum C3 level could be excluded as a reason probably.
