Fibulin protein family has widely existed in the extracellular matrix, and plays an important role in maintain the stable of basement membrane, elastic fibers and loose connective tissue. Fibulin-5 (FBLN-5) is one of the members of the Fibulin protein family, which is essential to the structure function and cell mediated action. The lack of FBLN-5 will cause many diseases such as internal organ deformity. Current research suggests that changes of expression level of FBLN-5 are associated with the occurrence of tumors such as lung cancer, and also can influence the tumor proliferation, invasion and prognosis, thus may become a new molecular marker for cancer diagnosis. Therefore, in this review, we summarize and update biological characteristics and functions of FBLN-5, and its role in the development of tumor formation mechanism.

The effects of superoxide dismutase (SOD) on mitochondrial function after hypoxic and reoxygenated perfusions in isolated rat hearts were observed. Significant decreases in respiration control ratio (RCR) and ADP/O ratio (P/O) as well as activities of succinic dehydrogenase (SDH) and cytochrome oxidase (CCO) were found alter 40 minutes' hypoxia and 20 minutes' reoxygenated perfusion. Adding SOD to the perfusion fluid during the reperfusion period could restore the decreased mitochondfial function, which was shown by increased RCR and P/O as well as activities of SDH and CCO.

Objective:To study the effect of breviscapine on visual function of the patients with primary open-angle glaucoma after filtration surgery. Methods:Twenty-nine cases (42 eyes) of patients with primary open-angle glaucoma at middle and late stage after filtration surgery were selected and randomly divided into the experimental group and the control group according to the defect degree of visual field. The 15 patients (21 eyes) in the experimengtal group ( TG) were intravenously injected 250ml saline containing 50mg breviscapine, while the 14 patients (21 eyes) in the control group (CG) were intravenously injected 250ml saline containing 1g vita-min C. The treatment course was 2 weeks followed by one-week withdrawal. After three treatment courses, the visual function in the two groups was investigated and compared before and after the treatment. Results:After the treatment, the visual field defect value and the thickness of retinal nerve fiber layer of the patients in TG were both better than those before the treatment (P<0. 01,P<0. 05). The values of visual acuity and visual field defect of the patients in TG were significantly better than those of the patients in CG ( P<0. 05, P<0. 01). Conclusion:After intraocular pressure is controlled, breviscapine injection can reduce the vision damage of patients with primary open-angle glaucoma at middle and late stage after filtration surgery and improve the visual field defect.

Objective To investigate the genotype and antifungal susceptibility of AspergiIlus species isolated from clinical settings and environmental sources. Methods Random amplification of polymorphic DNA (RAPD) analysis was performed to profile the genotypes of 48 Aspergillus fumigatus strains, 59 Aspergillus flavus strains and 30 Aspergillus niger strains isolated from clinical settings and environmental sources. NCCLS M38-A protocol was carried out for antifungal susceptibility testing of these Aspergillus isolates. Results As RAPD analysis showed, the 48 Aspergillus fumigatus strains were classified into 8 genotypes, 59 Aspergillus flavus strains into 12 genotypes, and 30 Aspergillus niger strains into 5 genotypes. A significant difference was observed in the susceptibility to terbinafine among the 8 genotypes of Aspergillus fumigatus (χ2 = 33.092, P <0.01 ) as well as in that to amphotericin B among the 5 genotypes of Aspergillus niger (χ2 = 15.185, P< 0.05).No statistical difference was found in the susceptibility to amphoteriein B, itraconazole, fluconazole or flucytosine among the 8 genotypes of Aspergillus fumigatus or in that to terbinafine, itraconazole, fluconazole or flucytosine among the 5 genotypes of Aspergillus niger. Conclusion There is some difference in the susceptibility to some antifungal agents between different genotypes of Aspergillus fumigatus and Aspergillus niger.

BACKGROUND:Previous studies have found that combined use of Buyang Huanwu decoction and bone marrow mesenchymal stem cel (BMSC) transplantation can play a synergic role against cerebral ischemia injury. OBJECTIVE:To analyze the effect of Buyang Huanwu decoction combined with BMSC transplantation to promote angiogenesis after cerebral ischemia. METHODS:Ninety-six Sprague-Dawley rats were randomly divided into four groups, and used to make middle cerebral artery occlusion models. In combined group, rats were given intragastrical administration of Buyang Huanwu decoction 10 mL/kg once a day, beginning at 3 days prior to modeling, and then given intragastrical administration of Buyang Huanwu decoction once at 2 hours after modeling, fol owed by its intragastrical administration every 12 hours. In BMSC and combined groups, BMSC suspension was injected into the rat ventricle after 2-hour cerebral ischemia/2-hour reperfusion, and then 30 minutes later, CD34 and CD45 antibodies were injected. In antibody group, CD34 and CD45 antibodies were injected. In model group, only normal saline was given. SerumαVβ3 level detection, immunohistochemical observation, Q-PCR and western blot tests were performed in the combined group at 12, 24, 36, 48 hours after reperfusion, while these indices were detected in the other three groups at 36 hours after reperfusion. RESULTS AND CONCLUSION:(1) The level of serumαVβ3 was lower in the antibody group than the model group (P<0.05), higher in the BMSC and combined groups than the antibody group (P<0.05), and higher in the combined group than the BMSC group (P<0.05). (2) Immunohistochemical findings showed that compared with the antibody group, the number of CD34 positive cel s was higher in the model, BMSC and combined groups (P<0.05). (3) Results from the Q-PCR and western blot assay showed that compared with the model group, the pFAK protein expression level was lower in the antibody and BMSC group, but FAK gene expression level had no overt changes;while the protein levels of FAK (24 hours after reperfusion) and pFAK (12 hours after reperfusion) were significantly increased in the combined group than the antibody and BMSC groups (P<0.05, P<0.01). Moreover, this increase exhibited a gradual y rising trend with the extension of reperfusion time. To conclude, the combined use of BMSC transplantation and Buyang Huanwu decoction can reverse the effect of CD34+CD45 antibodies that lead to the decrease in the number of vascular endothelial cel s and levels of integrinαVβ3 and downstream signaling molecules, thereby to promote angiogenesis in the MCAO model.
