Neovascular glaucoma ( NVG ) is a series of blinding and intractable eye diseases, which caused by various intraocular or extraocular diseases. The iris and angle neovascularization and vascular membrane fiber contraction may eventually lead to progressive elevation of intraocular pressure and angle closure. Because of complex etiology, the treatment of NVG is intractable and inefficient. Based on the articles published in recent years, we reviewed the progressions of the relevant cytokines and animal models.

Objective To observe the effect of simvastatin on intimal proliferation in abdominal aorta of rabbits after stenting.Methods Thirty male New Zealand white rabbits were allocated into two groups including the control group(n=15)and the treatment group(n=15).All the rabbits were fed on 1.5% high cholesterol diet and underwent ballon injury of abdominal aorta from femoral approach and stents were implanted in the segments with stenosis rate greater than 50%.Rabbits in the treatment group were given simvastatin 5 mg/d after stenting.Neointima proliferation of the stented segments was examined on the 30th day after stenting by histological staining and the expression of P27kip1 and PCNA in each group was also analyzed.Results Histological staining showed that on the 30th day after stenting,the thickness of vessel wall(0.107?0.072 mm vs 0.133?0.047 mm,P=0.006)and the area of neointima(0.975?0.084 mm2 vs 1.350?0.043 mm2,P=0.001)were less in the simvastatin treatment group compared with the control and the rate of lumen loss was less than that of the control(20.460%?2.325% vs 31.020%?1.904%,P=0.002).The expression of P27kip1 in the neointima VSMC cell nuclear was higher(7.149?0.305 vs 2.997?0.310,t=9.551,P

We used retrovial vector LXSN to construct recombinant retroviral vector with mutant membrane bound TNF - ? gene. The vectors were introduced into packaging cell line, CRIP cells. The G418-resistant colonies were selected and the supernatants of the colonies were used to determine the virus titers. The titer of virus was 1? 104CFU/ml and the retroviral vectors were used to tranduced the human gastric cancer cell line, MGC-803 cells. The results of southern blot assay showed thai the targel gene had integrated into the genomic DNA of MGC-803T. MGC - 803Tcells were ablc to kill L929 cell line, but the parent cell line showed no cytotoxicily to the cells at all. There was no any variance in the morphological appearance and growlh rate in vilro of MGC-803N and MGC-803T cells. The results of inoculation in nude mice with these cells indicated that MGC-803T cells showed a considerable decrease in size of tumor. These results suggested that the retroviral vectors expressing mulant TNF -? gene were successfully construed. MGC - 803T cells showed cytotoxicily slrongly lo L929 cell line in vilro and lumorigenicity .

Objective To explore the association between Q-1 and T1 locus polymorphism in ADAM33 gene and chronic obstructive pulmonary disease in Han population in northern Guizhou by detecting Q-1 and T1 locus polymorphism in ADAM33 gene in patients with COPD in the distribution of frequency ,provide a theoretical basis for the prevention and treatment of COPD. Methods Polymerase chain reaction and DNA sequencing tech-nology,electrophoresis separation method were applied to detect Q-1 and T1 locus polymorphism in ADAM33 gene. Results The genotype distribution of Q-1 and T1 locus in the case group and the control group of ADAM33 gene were in accordance with the Hardy-Weinberg equilibrium law and ADAM33 gene Q-1,T1 locus were C and T alleles. There was no significant difference in genotype and allele frequency distribution between the case group with control group,and COPD complicated with chronic respiratory failure(COPD)and hypoxemia(P > 0.05). T1(83 bp,112 bp)at a high probability of two heterozygous in the same samples(18/19),and is located in the encoding region. Conclusion No association was found between Q-1,T1 locus polymorphism in ADAM33 gene and chronic obstructive pulmonary disease in Han population in northern Guizhou.

Objective To analyze morbidity,mortality and epidemiological characteristics of epidemic encephalitis B (Japanese encephalitis) from 2002 to 2013 in Zunyi.Methods The descriptive and statistical analysis of the incidence and death of epidemic encephalitis B from 2002 to 2013 in Zunyi was carried out.Results The morbidity and mortality were on a downward trend of epidemic encephalitis B in Zunyi from 2002 to 2013;most of the death and incidence cases occurred in July and August from children living scattered and students under age 15;after immunization expansion,the incidence of encephalitis B showed significant differences between ages,occupations,and time points (P<0.05);in the regional distribution of epidemic encephalitis B,incidence and mortality had significant differences (P<0.05).Conclusion Promising results might be generally obtained after expansion of encephalitis B immunization.However,there is a tendency of shifting back in terms of onset age and month.Therefore,comprehensive prevention measures should be implemented according to the epidemiological features of epidemic encephalitis B.

Objective To study the antitumor effect and the mechanism of the polysaccharide from Gloipeltis furcata on H_(22),tumor bearing mice.Methods The polysaccharides from Gloipeltis furcata were administered by oral route in mice bearing H_(22) tumor.The treatments lasted for 7 days.The inhibition rate against H_(22) tumor and the indices of thymus, spleen and liver were measured.In addition,the levels of antibodies against H_(22) tumor and GPT in serum,and GPT,GOT,MDA and SOD in liver were measured using commercially available kits.Results The administration of the polysaccharides from Gloipeltis furcata(200 mg?kg~(-1)?d~(-1) and 400 mg?kg~(-1)?d~(-1) ) for 7 days,the inhibition rates of H_(22) tumor were 35.64%(P

AIM: To study the protection of extract of Radix Atragali composite against acute hepatic injury. METHODS: Fed with the extract of Radix Atragali composite, m ice were injected with D-galactosamine intraperitoneally (800 mg/kg) and rats were i njected with carbon tetrachloride hypodermically (5 mL/kg) to induce acute hepat ic injury on the 8th day. ALT, AST and bilirubin in serum were examined. Patholo gical changes of liver tissue were observed. RESULTS: Compared with model group, activities of ALT and AST, c oncentrations of bilirubin were markedly decreased and pathological scores also showed that degeneration and necrosis of hepatic cell were lighter in the the ex tract of Radix Atragali composite treatment group. CONCLUSION: The extract of Radix Atragali composite attenuat es hepatic injury induced by D-galactosamine or carbon tetrachloride.
