1.Cytological study on vitreous extracts in Eales disease
Chinese Journal of Experimental Ophthalmology 2001;19(3):217-219
To study the pathcytological mechanism of Eales disease and to provide a histological testimony for an effictive therapy.Methods45 cases(48 eyes) of Eales disease that were diagnosed according to vitreous hemorrhage and proliferative vitreoretinopathy or secondary retinal detachment.Cytomorphological examination was taken and vitreous extracts were examined by immunohistochemical staining.ResultLymphocytes and fibroblastes were most of those cells in the vitreous extracts.Immunohistology and electron microscopy revealed that lymphocytes were 78.8% or 61.5% in all specimens,respectively.ConclusionProliferative vitreoretinopathy induced by Eales disease closely relates with lymphocytes.The results suggested that autoimmunity might play an important role in the pathogenic mechanism of the disease

Objective To observe the effect of sinomenine on the proliferation of fibroblast-like synoviocytes (FLS) and expression level of MMP-3 secreted by FLS in rheumatoid arthritis in vitro. Methods FLS were obtained by digesting synovial tissues with collagens and were divided into four groups:sinomenine high, middle, low concentration and control group. The proliferation of FLS was assessed by methyl- thiazolyl-tetrazolium (MTT) assay and the mRNA expression of MMP-3 was measured by semi-quantitative RT-PCR respectively after treated by sinomenine. Results The rate of FLS proliferation was significantly reduced in groups treated by sinomenine. Compared with control group, the mRNA expression of MMP-3 markly decreased in sinomenine groups (P

Objective To investigate the effects of icariin on the expressions of osteoprotegerin(OPG)and receptor activator of nuclear factor-kB ligand(RANKL)mRNA in rat osteoblasts cultured in vitro.Methods Calvarial osteoblasts were obtained from newborn SD rats aged<24 h by trypsin-collagenase digestion method. After treatment with different concentrations of icariin(10~(-10)-10~(-4) mol/L)for 48 h,total RNA was isolated from osteoblasts.Expressions of OPG and RANKL mRNA were detected by semiquantitative RT-PCR.Results Icariin remarkably increased OPG mRNA levels and decreased RANKL mRNA levels in calvarial osteoblasts in a dose- dependent fasion with a maximum effect at a concentration of 10~(-7)mol/L(P<0.05).Osteoblasts pre-treated with icariin prevented the inhibitory effect of dexamethasone on OPG mRNA(0.570?0.093 vs 1.083?0.081)and the stimulative effect on RANKL mRNA(1.079?0.050 vs 0.718?0.082)(both P<0.05).Conclusion Icariin upregulates OPG expression and downregulates RANKL expression in osteoblasts,which may explain the beneficial role of icariin in preventing and treating osteoporosis.

International Eye Science 2016;16(10):1820-1823
AIM:To evaluate the regulatory effect of microRNA-132 ( miR - 132 ) in human umbilical vein endothelial cell ( HUVEC) .
●METHODS: ln vitro cultured human umbilical vein endothelia cells in hypoxic environment for 6h, then maintained under normal oxygen condition for 3h, 6h, 12h, 24h. miR-132 and peroxisome-proliferator-activated receptor-γ coactivator-1α ( PGC-1α) expression was detected by quantitative Real - time polymerase chain reaction and Western blot analysis. Human umbilical vein endothelial cells transfected miR-132 mimic and miR-132 inhibitor( anti-miR-132 ) were measured by quantitative Real-time polymerase chain reaction and Western blot.
●RESULTS: miR - 132 and PGC - 1α expression was significantly ( P < 0. 01 ) upregulated in the hypoxic environment of cells at 3h compared with the normal oxygen condition. After cells transfection, the hypoxic environment the miR-132 and PGC-1α expression were markedly increased compared with the normal oxygen condition. The cells transfected miR- 132- mimic, the expression of the miR-132 and PGC-1α were higher than that of transfected anti-miR-132 and contrast group ( P<0. 01).
●CONCLUSION:miR-132 level is highly expressed in the HUVEC under hypoxia and may be an effect of regulation for PGC-1α.

Objective To study the pathological characteristic of VX2 hepatic tumor in rabbit and the value of ultrasound in detecting this tumor mode. Methods To establish a model of Rabbit Liver VX2 Tumor with ultrasound- guided implantation of constitution mass and ultrasounds scanning was performed at fourteen days and twentyone days after implantation. After that, all the rabbits were executed and pathological examination was performed. Results Twenty models of Rabbit Liver VX2 Tumor were successfully established. The fourteen days after implantation,18 rabbits were found tumor,tumor diameter 8. 6 ~ 11.8 mm, average diameter ( 10. 15 ± 0. 67) mm; The twenty one days after implantation,20 rabbits were found tumor, tumor diameter 13.2 ~ 18.3 mm, average diameter( 16. 13 ±1.98)mm. Ultrasound showed that the tumor in the rabbit liver was a single spherical or sphere-alike hypoechoic nudes,and there were higher blood flow signals around the nedus. In pathological examination,the tumors were exserted to the liver surface,the cross sections of the tumor were gray,the cells of the tumors were bigger than the normal liver cells,arranged into nests with fibrous tissue. Conclusion In pathological examination, the heteromorphism of VX2 tumor cell was conspicuous. The growth of VX2 hepatoma could be monitored by ultrasound effectively.

Objective To study the effect of papaverine on vasospasm caused by PICC intubation with B-mode ultrasonography. Method Three mg papaverine were injected into the median cubital vein for at least 2 minutes in 15 patients with vasospasm. Results The vasospasm in the 15 patients was relieved 36~270 s seconds after injection. The followed intubation was all successful. There was no abnormality in their liver function and heart rate, or abnormal bleeding, or other serious complications. Conclusion Papaverine can relieve vasospasm caused by PICC intubation, so it can allow another intubation. It also can avoid delayed intubation reduce patients′pain and cost and reduce psychological pressure of the nursing practitioner.
