To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

AIM: To compare the difference of A-scan and lOL Master in intraocular lens power measurement.
●METHODS:Two hundred and twenty-six patients (230 eyes) with age-related cataract were included in the study. Before surgery, axial length was measured by A-scan and lOL Master respectively and corneal curvature was measured by auto refractometer. lntraocular lens power was calculated according to the SRK-T formula. Corneal curvature was measured by auto refractometer and the refractive outcome was performed by phoropter three months after cataract surgery.
●RESULTS:The mean axial length was (23. 48 ± 1. 94) mm measured by A-scan and (23. 75±1. 96) mm measured by lOL Master. There was significant difference between them ( P < 0. 05 ). After random grouping, the preoperative and postoperative mean corneal curvature in A-scan group was (43. 94±1. 81) D and (43. 98±1. 87) D respectively. There was no statistically significant difference between them (P>0. 05). And the results were (44. 10 ± 1. 57 ) D and ( 44. 11 ± 1. 58 ) D in lOL Master group. There was no significant difference between them (P>0. 05); The mean absolute refractive error (MAE) in A-scan group was ( 0. 47 ± 0. 27 ) D and in lOL Master group (0. 41±0. 19) D. The difference was significant (P<0. 05).
●CONCLUSION: lOL Master is proved to be slightly more accurate than A-scan for lOL power calculation.

Objective To investigate the expression of macrophage migration inhibitory factor (MIF) and CD_(74), the receptor of MIF, in preeclamptic placenta and its correlation with the pathogenesis of preeclampsia.Methods From March 2008 to November 2008,69 preeclamptic women who delivered in the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College,were recruited,including 33 women with mild preeclampsia (MPE group) and 36 women with severe preeclampsia (SPE group).Another 43 healthy pregnant women were taken as control group.Immunoturbidimetry was applied to measure the concentrations of C-reactive protein (CRP) in maternal blood.The expressions of MIF and CD_(74) in placenta were tested with immunohistochemistry and the expressions of MIF mRNA and CD_(74) mRNA were detected by semiquantitative RT-PCR.The relationship between maternal blood level of CRP and MIF mRNA and CD_(74) mRNA in placenta was analyzed in the MPE and SPE group.Results (1) MIF and CD_(74) were expressed in the placenta of all pregnant women in the 3 groups, as shown in brown-yellow color, and significantly higher expression was found in the MPE and SPE group.(2) The expression of MIF mRNA and CD_(74) mRNA in the MPE group (0.70±0.13 and 0.96±0.16), SPE group (0.88 ± 0.12 and 1.08 ± 0.15) were significantly higher than in the control group (0.67 ± 0.11 and 0.83 ± 0.14) (P < 0.01), and statistical significance was also found between the MPE and SPE group (P <0.01).(3)The maternal blood concentrations of CRP in the MPE and SPE group were significantly higher than in the control group [(15.3±7.0) mg/L and (21.6±9.1)mg/L vs (4.8 ± 1.8) mg/L, P <0.01] , and significant difference was also found between the MPE and SPE group (P <0.01).(4) In the two preeclamptic groups, the blood concentrations of CRP were positively correlated with the expression of both MIF mRNA(r =0.67 ,P <0.01)and CD_(74) mRNA(r =0.83 ,P <0.01) in placenta.Positive correlation was also found between the levels of MIF mRNA and CD_(74) mRNA in placenta (r =0.93 ,P < 0.01).Conclusions Overexpression of MIF and CD_(74) in the placenta may up-regulate the CRP level in maternal blood, resulting in systemic inflammatory reaction and vascular endothelium damage which may be involved in the pathogenesis of preeclampsia.

OBJECTIVE:To learn the application and tendency of hepatoprotective drugs in a third grade class A hospital dur-ing 2011-2014,and to provide reference for rational drug use. METHODS:DDDs analysis and consumption ordering method were adopted to analyze the change of DDDs,DDC and other index of hepatoprotective drugs in this hospital from 2011 to 2014. RE-SULTS:2011-2014,the amount and DDDs of Hepatoprotective injection in this hospital increased year by year,while oral dosage form decreased year by year. DDC order of each drug kept stable during 2011-2014;DDC and DDDs of drugs for promoting ener-gy metabolism were all in high level,and ornithine aspartate and ademetionine always took up the first 2 places in 4 years. Polyene phosphatidylcholine and Reduced glutathione injection were cheap,but had higher DDDs. Except Glutathione tablet,DUI of other hepatoprotective drugs had no great difference in 3 years,and fluctuated in 2014;hepatoprotective drugs with DUI>1 and DUI<1 occupied a large proportion. From 2010 to 2014,compared with previous year,the drugs with consumption sum/DDDs ratio num-ber close to 1 reduced significantly in the next year,decreasing year by year. CONCLUSIONS:In this hospital,injections are used too frequently,and overuse of drugs for promoting energy metabolism exist. Polyene phosphatidylcholine and Reduced glutathione injection can be used as a valuable drug in the clinic,and their cost are more acceptable,but not in excess.

Objective To investigate genotypes and antibiotic resistance of Escherichia coli producing plasmid-mediated AmpC ?-lactamase in Anhui province.Methods A total of 407 clinical isolates of nonrepeated Escherichia coli were collected from different cities in Anhui province.AmpC ?-lactamase producing isolates were identified by cefoxitin three-dimensional test and antibiotic susceptibility was identified by agar dilution test.Plasmid extraction,PCR amplication of corresponding group was performed, followed by sequencing.Results The positive rate of cefoxitin three-dimensional test was 8.1% (33/407), and the prevalence of plasmid-mediated AmpC ?-lactamase was 3.0% (12/407).bla_(CMY-2) gene,bla_(DHA-1) gene and bla_(ACT-2) gene were identified by PCR amplification and confirmed by sequencing in 5 strains,4 strains and 2 strains,respectively.A new CMY genotype was identified,with its sequence revealed 97% identity to the deduced amino acid sequence with previous CMY-2.This is also the first report on ACT-2 genotype in China.The susceptibility test showed that all strains were resistant to cephamycins and piperacillin,and susceptible to imipenem.Two strains of Escherichia coli producing DHA-1 were resistant to fourth-generation cephalosporin.Conclusions CMY-2,DHA-1 and ACT-2 are the most common genotypes in plasmid-mediated AmpC ?-lactamase produced by clinical Escherichia coli isolates in Anhui province. Carbapenems could be the first choice for the treatment of infection caused by AmpC ?-lactamase producers.

To observe the chelation of GRP78 with lead (Pb) and its localization changes, astroglial cells from Wistar rat brain were primarily cultured in medium with acetate Pb. The processes were terminated at different time points. The immunoprecipitation (IP) and Western blotting were used for GRP78 purification and expression and the Pb concentration was determined by employing atomic absorption spectrophotometry (AAS). The localization change of GRP78 was observed with colloid gold immunoelectron microscopy. The results showed that the expression of GRP78 was increased significantly in the cells treated with 1.0 mumol/L acetate Pb for 24 h and peaked at 96-192 h (P<0.01), and at the 12th day, the expression of GRP78 began to decrease but was still higher than normal (P<0.05). Pb content started to increase when cells were treated by acetate Pb for 24 h, and the peak appeared at 8 day (P<0.01), and then Pb content decreased gradually, but was still higher than normal (P<0.05). GRP78 protein expression began to remarkably increase when it transferred from ER to the cytosol around the nuclei 24 h after treatment with Pb. It is concluded that GRP78 in astroglia could strongly chelate with Pb ions and it might be a target protein of Pb.
