Corticosteroid-induced glaucoma (CIG) is a form of open angle glaucoma associated with both topical and systemic administration of corticosteroids. Here we described the clinical findings in a patient with severe glaucoma and posterior subcapsular cataract (PSC) after topical administration of corticosteroid eye drops. We concluded corticosteroid eye drop was an effective medicine for inflammation of the eyes; however,prolonged use could cause severe vision loss as a result of intractable corticosteroid-induced glaucoma and cataract.

Objective To investigate the clinical application value of stathmin, p16 and Ki-67 in the cervical intractable cases. Methods Immunohistochemical method was used to detect the expressions of stathmin, p16 and Ki-67 in surgical specimens of 288 cervical intractable cases, including 30 cases of cervical benign changes, 70 cases of cervical intraepithelial neoplasia (CIN)Ⅰ, 78 cases of CINⅡ, 85 cases of CINⅢand 25 cases of squamous cell carcinoma (SCC, as control group). The application value of stathmin, p16 and Ki-67 in the cervical cases were analyzed. Results The positive expression rates of Ki-67 of cervical benign changes and CINⅠwere 20.0 % (6/30) and 54.3 % (38/70) (χ2 = 3.29, P> 0.05). The expression rates of Ki-67 in CINⅡ, CINⅢ and SCC were all 100.0 %, and compared with the cervix benign changes, the differences were statistically significant (χ2= 112, P< 0.05). The expression rates of p16 in cervical benign changes and CINⅠwere 6.7 % (2/30) and 91.4 % (64/70), and there was significantly statistical difference (χ2=50.64, P<0.05). However, the expression rates of p16 in CINⅡ, CINⅢand SCC were all 100.0%, and compared with the cervix benign changes, the differences were statistically significant (χ2= 7.18, P< 0.01). The expression rates of stathmin in cervical benign changes, CINⅠ, CIN Ⅱ, CINⅢ and SCC were 3.3 %(1/30), 5.7 % (4/70), 23.1 % (18/78), 77.0 % (67/87) and 100.0 % (25/25), respectively, and there was no statistic difference in cervical benign changes, CINⅠand CINⅡ (χ2=0.68, P>0.05), but the expression rates in CINⅢ and SCC were higher than those in cervical benign change, CINⅠand CIN Ⅱ(P< 0.01). The positive expressions of stathmin, p16 and Ki-67 in each group of CIN were positively correlated (r= 0.412, P< 0.05). Conclusions Combined detection of p16 and Ki-67 can assist in the differential diagnosis of cervical intractable cases, and provide objective indicators for the classification and accurate diagnosis of CIN. Combined detection of p16 and stathmin may help to identify high-grade, low-grade CIN and cervix benign changes for the reduction of over-treatment.

AIM: To investigate the mechanism of AngRem104-mediated regulation of fibronectin gene in human mesangial cells. METHODS: A series of deleted FN promoter sequences was constructed, which fuse to a luciferase reporter gene, and then the potential active regions that respond to AngRem104 in the upstream regulatory sequence of human FN gene was screened by detecting the luciferase activity of promoter-reporter gene. RESULTS: The detection of relative luciferase activity revealed that there was no significant differences when the HMC were transfected with FN122-reporter gene together with sense AngRem104 construct, but the luciferase activity significantly increased when transfection of FN507-reporter gene construct together with sense AngRem104 construct. However, no increase in luciferase activity was observed when transfection of FN1280-reporter gene construct together with sense AngRem104 construct. The potential regulatory region responds to AngRem104 is in the upstream sequence (-122 to -507) of human FN gene. CONCLUSION: Our preliminary study provided the evidence that AngRem104 may mediate the transcription of the FN gene via the activation of its promoter.

ObjectiveTo investigate the differences of whole blood chemical elements and urinary fluorine between patients with endemic fluomsis and patients without endemic fluorosis,and to find out the elements associated with endemic fluorosis and further lay a theoretical basis for clarify the pathogenesis of the disease.MethodsUsing case-control study,100 children aged 8 - 12 with dental fluorosis in Wushan and Fengjie counties of Chongqing from December 2010 to February 2011,and 30 adults with skeletal fluorosis were enrolled as case group; 100 children aged 8 - 12 without dental fluorosis and 30 adults without skeletal fluorosis were enrolled as internal control group; and 50 children without dental fluorosis and 30 healthy adults were selected as external control group in non-epidemic areas in Yubei district.Whole blood copper,zinc,calcium,magnesium,iron and urinary fluorine of all subjects were determined,and differences of these indexes were compared between groups.ResultsThe levels of copper,zinc,calcium,magnesium,iron and urinary fluorine of children in the case group were (30.08 ± 2.83),(74.04 ± 9.75)μmol/L,(1.65 ± 0.29),(1.37 ± 0.17),(6.79 ± 1.27)mmol/L,and (0.73 ±0.37)mg/L,respectively; the levels of these elements of children in internal control group were (28.65 ± 3.96),(72.83 ± 11.35)μmol/L,(1.62 ± 0.27),(1.36 ± 0.18),(6.73 ± 1.22)mmol/L,and (0.48 ± 0.21)mg/L,respectively; in external control group were (32.03 ± 2.99),(77.78 ± 10.85)μmol/L,(1.41 ± 0.11),(1.43 ± 0.13),(7.66 ±0.55)mmol/L,and (0.49 ± 0.26)mg/L,respectively(all P＜ 0.05),the comparison between any two groups indicated the levels of copper,zinc,magnesium,iron of the case group were lower than that of external control group,urinary fluorine was higher than that of internal and external control groups(all P ＜ 0.05).The levels of copper,zinc,calcium,magnesium,iron and urinary fluorine of adult case were (26.93 ± 4.37),(95.89 ± 12.45)μmol/L,(1.50 ± 1.76),(1.56 ± 1.96),(8.15 ± 1.00)mmol/L,and (2.17 ± 0.99)mg/L; internal control group were (26.26 ±4.96),(94.86 ± 12.18)μmol/L,(1.57 ± 0.12),(1.46 ± 0.16),(7.64 ± 1.00)mmol/L,and (1.44 ± 1.22)mg/L;external control group were (26.20 ± 2.96),(96.52 ± 11.11)μmol/L,(1.48 ± 0.14),(1.45 ± 0.16),(7.81 ±0.91 )mmol/L,and (0.55 ± 0.21 )mg/L,respectively.The levels of magnesium,iron and urinary fluorine of case group were higher than that of internal control group,magnesium and urinary fluorine were higher than that of external control group(all P ＜ 0.05).ConclusionsIn vivo anti-fluorine elements are deficient in the areas with endemic fluorosis.Other chemical elements,the environment and genetic factors may be related to the pathogenesisof the disease,which needs a further comprehensive analysis.

Objective To investigate the correlation between the serum ghrelin levels and nutrition state in the patients with chronic obstructive pulmonary disease(COPD) ,as well as to explore the role of ghxelin in the nutri-tion metabolism. Methods Fifty-three COPD patients were observed, thirty-one of them were with malnutrition (group A), twenty-two COPD patients with normal nutrition status(group B), and twenty were healthy controls.Serum ghrelin, and nutritional parameters such as body mass index(BMI), ideal body weitht( % IBW), mid-upper arm cricumference(MAC), serum albumin(ALB), total lymphocyte counts(LYM) were determined. The correlation between ghrelin and nutritional parameters was analysed. Resuits The level of serum ghrelin in group A were sig-nificantly higher than those in group B and in healthy controls. And the serum ghrelin showed a negative correlation with BMI, % IBW, MAC, but there was no correlation between serum ghrelin level, ALB and LYM. Conclusion Ghrelin participated in the nutrition metabolism in patients with COPD, it would become much higher because of malnutrition in COPD.

Objective To explore the dynamic expressions of interleukin-1 (IL-1)receptor associated kinase (IRAK)-M and IRAK-4 in rats with or without endotoxin tolerance (ETT)in acute liver failure (ALF).Methods Sixty-six male SD rats were divided into three groups:ALF group,ETT group and control group.The rats in ETT group received daily lipopolysaccharide (LPS)intraperitoneal injection for 5 days,while the rats in ALF group received daily injection with same volume of 0.75% NaCl solution.Both ETT group and ALF group received intraperitoneal injection with D-galactosamine (D-GalN)and LPS at 24 hours after the 5th injection of LPS or NaCl solution.At 2,6,12,24 and 48 h after D-GalN and LPS injection,the serum levels of tumor necrosis factor-α (TNF-α)and interleukin-6 (IL-6)were detected by enzyme-linked immunosorbent assay (ELISA).The liver pathologic changes were observed with HE staining by microscope.The mRNA expressions of IRAK-4,IRAK-M and NF-κB (p65)were detected by reverse transcriptase polymerase chain reaction (RT-PCR).The pairwise comparison between groups was done by lease significant difference (LSD)and Dunnet's t test.Results The liver pathologic changes in ETT group were much milder than those of ALF group.In ALF group,IRAK-4 mRNA/β-actin absorbance ratios at 2,6,12,24and 48 h after D-GalN and LPS challenge were 0.711 ±0.074,0.904±0.118,1.012 ±0.098,1.534±0.279 and 1.451±0.290,respectively,while the IRAK-M mRNA/β-actin absorbance ratios were 0.496±0.018,0.516±0.089,0.503±0.023,0.503±0.057 and 0.469±0.142,respectively.In ETT group,the IRAK-4 mRNA/β-actin absorbance ratios at 2,6,12,24 and 48 h after D-GalN and LPS challenge were 0.619±0.083,0.587±0.033,0.623±0.034,0.720±0.044 and 0.654±0.041,respectively,while the IRA'K-M mRNA/β-actin absorbance ratios were 0.929 ± 0.064,1.111±0.138,1.113±0.027,1.891±0.315 and 1.710±0.303,respectively.The IRAK-M mRNA expression level was significantly increased and IRAK-4 mRNA expression level was relatively decreased in ETT group compared to ALF group.The differences were all statistically significant at 2,6,12,24 and 48 h after D-GalN and LPS challenge (F= 17.305,54.921,121.031,67.607,55.279,respectively; F=19.506,43.777,110.823,302.681,202.822,respectively; F=172.003,59.519,987.055,68.463,96.601,respectively; all P＜0.05).Conclusion LPS pretreatment may induce ETT in rat model by downregulating the expression of IRAK-4 and upregulating the expression of IRAK-M.
