Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.

Background Ultraviolet radiation is one of factors of the formation of age-related cataract.Indole-3-carbinol(I3C) is a plant chemical material with inhibitory effect on oxidative-induced cell damage and formation of amyloid fibrils,and the oxidative damage and amyloid fibrils are associated with cataract.However,the relationship between I3C and α-crystallin is in study. Objective This study was to evaluate the effects of ultraviolet-B laser irradiation on the secondary structure of α-crystallin and to explore the protection of I3C to chaperone activity of α-crystallin. Methods The fresh eyeballs were obtained from 1-year-old cattle to prepare the purified lens α-crystallin by gel chromatography.α-Crystallin was isolated from cattle lenses using gel chromatography.The purified α-crystallin was collected using fast protein liquid chromatography ( FPLC ) and exposed to 1:308 nmultraviolet-B at different irradiation intensities ( 23.75,118.75,475.00,1187.50,2375.00,4750.00,11 875.00,23 750.00 mJ/cm2 ) and then to ultraviolet-B 2:308 nm with irradiation intensities of 28 535.00,6730.00,3435.00,1910.00,1040.00 mJ/cm2.Ultraviolet-absorbance spectra,tryptophan fluorescence and N-formylkynurenine (N-FK)fluorescence spectra of both irradiated and non-irradiated α-crystallin were measured.I3C at the concentrations of 50 μmol/L and 100 μmoL/L were added to the α-crystallin solution to perform a catalase (CAT) thermal aggregation to confirm the chaperone activity of the α-crystallin,and the α-crystallin solution without any I3C was used as control.The ratios of A360 between various intervene groups with control group were calculated using spectrophotometry.Results The A280 values of the α-crystallin declined to 10％ at the ultraviolet-B irradiation intensity of 1187.5 mJ/cm2 and that at the intensity of 23.75 J/cm2 lowed to 2％.A negative correlation was seen between the ultraviolet-B irradiation intensity and the A280 value of the α-crystallin (R2=0.925 ) and a positive correlation was found between ultraviolet-B with N-FK ( R2 =0.949 ).Ultraviolet-B irradiation intensity showed a negative correlation with Trp fluorescence intensity (R2 =0.996 ).CAT hot condensed experiment revealed that after addition of different concentrations of indole-3-carbinol,the relative A360 values at various ultraviolet-B irradiation group were significantly higher than those of the control group (P =0.000),and the decreasing degree of chaperone activity of α-crystallin was lower than that of the control group ( P =0.000 ). Conclusions The study suggests that I3C can protect the chaperone activity of α-crystallin from photooxidation,and the ultraviolet-B laser may be a good exposure source compared with ultraviolet lamp.The ultraviolet-B laser irradiation causes the alteration of structure and chaperone activity of α-crystallin.

Objective To study the effect of recombinant human edostatin on peritoneal angiogenesis in uremic peritoneal dialysis(PD) rats. Methods Forty male SD rats were randomly divided into 5 groups: normal control rats (group 1), renal failure without PD rats (group 2), rats dialyzed with 4.25% PD solution (group 3), rats dialyzed with 4.25% PD solution and received subcutaneous injection of recombinant human endostatin 10 mg/kg (group 4), rats dialyzed with 4.25% PD solution and received subcutaneous injection of recombinant human endostatin 40 mg/kg (group 5). Recombinant human endostatin was given every other day during peritoneal dialysis period, total 14 times. After regular PD for 28 days, tissue immunohistochemical staining and RT-PCR were used to detect the mRNA and protein expressions of VEGF and bFGF in peritoneal tissues of each group rats. Microvessel density (MVD) of peritoneum was detected and quantified with anti-CD34 immunohistochemical staining. Results The mRNA and protein of VEGF and bFGF were expressed in each group. Compared to group 1, the mRNA and protein expression of VEGF and bFGF were significantly up-regulated in group 2 and group 3 (all P＜0.05). Compared with group 3, the mRNA and protein expression of VEGF and bFGF were significantly downregulated in group 4 and group 5 (all P＜0.05). Compared with group 4, the mRNA and protein expression of VEGF and bFGF were significantly down-regulated in group 5 (all P＜0.05). The new microvascular vessels in group 1 showed little or none. Compared with group 1, MVD was significantly increased in group 2 and group 3 (P＜0.05). Compared with group 3, MVD was significantly decreased in group 4 and group 5 (all P＜0.05). Conclusions Recombinant human endostatin can effectively inhibit rat peritoneal neoangiogensis. Down-regulated expression of VEGF and bFGF in peritoneum may be one of the mechanisms of recombinant human endostatin inhibiting peritoneal angiogenesis.

BACKGROUND:Recent studies have shown that α2-adrenergic agonists can reduce postresuscitation myocardial injury. This study was undertaken to observe changes of hemodynamics, myocardial injury markers cTnT and cardiac morphology by establishing a cardiopulmonary resuscitation model with rabbits, and to detect whether α-methyl norepinephrine (α-MNE) can reduce the myocardial injury after CPR and improve cardiac function. METHODS:Eighteen health rabbits, weighing 2.5-3.5 kg, both male and female, were provided by the Lanzhou Institute of Veterinary Medicine. After setting up a rabbit model of cardiopulmonary resuscitation, 18 rabbits were randomly divided into three groups. The rabbits in group A as an operation-control group were subjected to anesthesia, endotracheal intubation, and surgery without induction of ventricular fibrillation. The rabbits in group B as an epinephrine group were administered with 30 g/kg epinephrineduring CPR. The rabbits in group C as a MNE group were administered with 100 g/kg a-MNE during CPR. The left ventricular end-diastolic pressure (LVEDP), left ventricular pressure rise and fall rate (±dp/dt) and serum concentrations of BNP were measured. Statistical package of SPSS 10.0 was used for data analysis and significant differences between means were evaluated by ANOVA. RESULTS:Compared to group A, the LVEDP of other two groups increased respectively (P<0.01 all), and peak±dp/dt decreased in the other two groups (P<0.01). The increase of LVEDP was lower in group C than in group B (P<0.05), whereas peak±dp/dt was higher in group C than in group B (P<0.05) at the same stage. Compared to group A, the cTnT of the remaining two groups increased, respectively (P<0.01), and peaked at 30 minutes. cTnT was less elevated in group C than in group B (P<0.05) during the same period. In groups B and C, myocardial injury was seen under a light microscope, but the injury in group C was lighter than that in group B. CONCLUSION:Methylnorepinephrine can lessen myocardial dysfunction after CPR.

Methods The surveillance data of 458 children infected with ALRTI in 10 sentinel hospitals in Gansu province from 2012 to 2015 were collected, and infection status and epidemiological characteristics of each virus and bacteria were analyzed by descriptive study methods. Results The male to female ratio of the 458 children with ALRTI was 1.81:1, and the positive detection rate of the virus was 33.62%（95% CI：29.28%-37.97%), among which the positive detection rate of respiratory syncytial virus was the highest (12.23%).The positive detection rate of bacteria was 24.84%（95% CI：20.04%-29.65%),among which the positive detection rate of streptococcus pneumoniae was the highest (18.47%).There was significant no difference in the positive detection rate of virus and bacteria between children of different genders (P>0.05).There was significant no difference in the positive detection rate of virus among children of different age groups ( 2=5.980,P=0.050), but the positive detection rate of bacteria was different ( 2=12.078,P=0.002).Positive detection rates of virus infection and bacterial infection were different in distinct seasons (all P<0.05). By using logistics regression analysis, season, age and sentinel hospital were the influencing factors of ALRTI virus infection in children (all P<0.05), and sentinel hospital and years were the influencing factors of ALRTI bacterial infection in children (all P<0.05). Conclusion Respiratory syncytial virus, influenza virus and parainfluenza were the main causes of ALRTI virus infection in children aged 0-14 years in Gansu province, and the main bacterial infections were streptococcus pneumoniae and haemophilus influenzae, the number of virus infection was more than that of bacterial infection. Viral and bacterial infection had the same peak incidence.

OBJECTIVETo study the clinical outcome, adverse effect and treatment cost of homoharringtonine (HHT) in combination with all-trans retinoic acid (ATRA) and arsenic trioxide (AS2O3) for newly diagnosed with patients acute promyelocytic leukemia (APL).

METHODSClinical data of treatment of newly diagnosed patients with APL in experimental group (HHT + ATRA + AS2O3, n = 14) and control group \[Idarubicin (IDA) + ATRA + AS2O3, n = 21\] were analyzed retrospectively. The therapeutic effects, side effects and costs during induction therapy were compared between the two groups.

BACKGROUND: Henoch-Schonlein purpura (HSP) is an immune complex-mediated disease predominantly characterized by the deposition of circulating immune complexes containing immunoglobulin A (IgA) on the walls of small vessels. Although the pathogenesis of HSP is not yet fully understood, some researchers proposed that B-cell activation might play a critical role in the development of this disease. OBJECTIVE: To investigate the serum levels of visfatin (pre-B-cell colony-enhancing factor), B-cell-activating factor (BAFF), and CXCL13, and to analyze their association with disease severity. METHODS: The serum levels of visfatin, BAFF, and CXCL13 were measured by using a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) in 43 patients with HSP and 45 controls. The serum levels of IgA anticardiolipin antibodies (ACA) were detected by using a double-antigen sandwich ELISA. RESULTS: Levels of visfatin but not BAFF and CXCL13 were significantly elevated in the sera of patients with HSP in the acute stage, and restored to normal levels in the convalescent stage. Furthermore, serum levels of visfatin were significantly higher in patients with HSP having renal involvement than in those without renal involvement. Serum levels of visfatin were correlated with the severity of HSP and serum concentration of ACA-IgA. CONCLUSION: We show for the first time that the serum levels of visfatin are abnormally elevated in patients with HSP. Visfatin may be associated with the pathogenesis of HSP.
