2.Effects of intravitreal injection of Lucentis for anterior segment neovascularization indeced by central retinal vein occlusion
International Eye Science 2016;16(8):1573-1575
Abstract?AIM:To investigate the therapeutic effect of Lucentis in the treatment of anterior segment neovascularization ( ASNV ) induced by central retinal vein occlusion ( CRVO) .?METHODS: This was a retrospective case series study for patients with ASNV secondary to CRVO from January 2013 to December 2014 and treated with intravitreal injection of lucentis. Best visual acuity ( BCVA ) , intraocular pressure ( IOP ) , iris examination and gonioscopy, and if necessary, fluorescein angiography and optical coherence tomography, were recorded.The follow-up time was 6-13mo, the average was 9.1 ± 2.9mo.?RESULTS: Eighteen patients ( 18 eyes ) were treated with intravitreal injection of lucentis;15 patients (15 eyes) of the 18 were treated with panretinal photocoagulation;the other 3 patients 3 eyes were not received the photocoagulation because of vitreous opacity. One patient was treated with glaucoma valve implantation.Six patients with only neovascularization and without glaucoma were improved in visual acuity whose intraocular pressure was controlled after combined treatment.Of the patients with neovascular glaucoma ( n=12 ) , after intravitreal injection of lucentis and panretinal photocoagulation, the IOP was controlled in 4 patients (4 eyes);the IOP of another 7 cases reduced but glaucoma drugs were still needed.One patient ( 1 eye ) received glaucoma valve implantation because of bad control on IOP with worse vision after implantation.The rubeosis disappeared in all patients.?CONCLUSION:Intravitreal injection of lucentis can stop neovascularization and help to control IOP.In the early stage without neovascular glaucoma, lucentis has better effects, which means early detection and intervention are important.

Journal of Medical Postgraduates 2004;0(01):-
Because absence of lymphoadenopathy, and often associated with haemophagocytic syndrome, the intravascular malignant lymphoma(IVL) is easy mistaken as malignant histiocytosis or connective tissue disease or vasculitis, the diagnosis was difficult while patients were alive. The clinical course of this disorder (IVL)was aggressive and carried a poor prognosis. The cases of this disorder are not too rare to be seen in our country. To enhance one′s ability to differentiate disorder in unknown fever diseases are extremely necessary.

A deficient of plasma VW factor-cleaving protease (ADAMTS13) and appearance of unusually large multimers induced platelets aggregation in capillaries and arterioles. It was critical pathogenesis of thrombotic thrombocytopenia purpura (TTP). ADAMTS13 activity has been measured over 1000patients of TTP and hemolysis uremia syndrome (HUS) since 1997. Diagnostic sensitivity and specificity,as well as clinical significance of ADAMTS13 deficiency for TTP patients were evaluated,and synthetical diagnosis basis of TTP were raised.
6.Study Progress of Infantile Spasms in Molecular Genetics
Journal of Applied Clinical Pediatrics 1994;0(04):-
Infantile spasms is a type of refractory epilepsy syndrome.This epilepsy syndrome is characterized by special tonic spasms,a peculiar set of electroencephalographic findings termed hypsarrhythmia,and arrest of psychomotor development in most patients.The etiology is not clearly understood.Recently,mutations of the arista less related homeobox gene(ARX),cyclin-dependent kinase-like 5(CDKL5)/se-rine/threonine kinase 9 gene(STK9),membrane associated guanylate kinase 2 gene(MAGI2),et al,and abnormal chromosome had been found to be responsible for infantile spasms.In this review,progress of infantile spasms in molecular genetics are discussed.
7.Inhibition of mevastatin on inflammation and differentiation of orbital preadipocytes in thyroid-associated ophthalmopathy
Chinese Journal of Experimental Ophthalmology 2011;29(10):907-912
Background Inflammation and adipogenesis are two parallel processes with increasing activity in severe thyroid-associated ophthalmopathy(TAO),and mevastatin was proved to have the inhibiting effect on the differentiation of adipose.Objective The aim of this work was to investigate the effects of mevastatin on the expression of cyclooxygenase-2(COX-2)and peroxisome proliferator activated receptor-γ(PPAR-γ)and differentiation of TAO-derived orbital preadipocytes,and explore its modulation effects on lipopolysaccharide(LPS)induced inflammation and the differentiation of TAO-derived orbital preadipocytes in vitro.Methods The retroorbital adipose tissue was obtained from 4 TAO patients during the surgery.The orbital fibroblasts were cultured from orbital adipose tissues using explant culture method.To study the suppressing effect of mevastatin on inflammatory response,cultured cells were divided into 5 groups.The 1000 μg/L LPS orbital fibroblasts were stimulated for 8 hours in group A,and 1000 μg/L LPS combined with 5 μmol/L,10 μmoL/L or 20 μmoL/L mevastatin were used respectively for the substitute in the group B,group C and group D.The orbital fibroblasts in group E were cultured routinely without any intervention as control.To observe the inhibiting effect of mevastatin on the differentiation of adipose,the group A were then subdivided into group A1-A6.After 1000 μg/L LPS was used to treat the cells for 8 hours,the ceils were induced to differentiate into adipocytes.All orbital preadipocytes from A1 to A6 were stimulated to differentiate into mature adipocytes with cocktail differentiation medium for a 10-day duration.During the procedure,group A2,A3 and A4 were interfered with 5,10 or 20 μmol/L mevastatin,and in the group A5 and A6,10 μmol/L mevastatin were added at the fourth day or eighth day.Intracellular fat accumulation in differentiated adipocytes was determined by oil red O staining.The absorption(A492 nm)was measured in the ceils by enzyme-linked immunosorbent assay(ELISA).Expression of COX-2 and PPAR-γ mRNA was detected by reverse transcription polymerase chain reaction(RT-PCR),and the expression of COX-2 and PPAR-γ protein was detected by Westernblot.The level of PGE2 in the supernatant was detected by ELISA.Results The expression of COX-2 protein and mRNA as well as the PGE2 levels in B,C,D group decreased markedly in comparison with those in A group(P<0.05).With the increase of mevastatin concentration,the expression of COX-2 protein and mRNA as well as the PGE2 levels in B,C,D groups decreased successively(F =228.380,101.745,1586.881,P<0.05).The expression of COX-2 protein and mRNA and PGE2 levels in E group were lower significantly than those in A,B and C groups(P<0.05),but no significant differences were found between E group and D group(P>0.05).The A492 value and the expressions of PPAR-γ protein and mRNA in differentiated cells showed the successively decrease in A1-A4 group with the elevation of mevastatin concentration(P<0.05),and the evidently decreased A492 value and the expressions of PPAR-γ protein and mRNA also were seen in A1 and A5 groups compared with A3 group(P < 0.05).Conclusions Mevastatin inhibits LPS-induced COX-2 expression,PPAR-γ expression,PGE2 secretion and differentiation of TAO-derived orbital fibroblasts in vitro in dose-dependent manner.Mevastatin plays these effect more prominently in early stage of adipocytes differentiation.

The temperature and salinity ranges for growth of twelve strains of marine Bdellovibrio-and-like organisms (BALOs) which affiliated with four different phylogenetic clusters in the family Bacteriovoracaceae and the lytic ability of them to six kinds of common shrimp pathogen vibrios were studied. The morphological characteristics of four representative strains were examined with transmission electron microscope. The results showed that the strains within the same cluster or sub-cluster had identical growth temperature or salinity. The growth temperature ranges of clusters IV, VI, IX and X strains were 20?C~35?C, 15?C~35?C, 15?C~40?C, 10?C~40?C, respectively, and the optimum growth temperature was about 30?C or 35?C. The growth salinity ranges of clusters IV, VI, IX and X strains were 5‰~40‰, 2.5‰~30‰, 5‰~60‰ and 5‰~60‰, and the optimum salinities were about 10‰, 5‰, 20‰ and 20‰, respectively. Three of the six kinds of vibrios tested were lysed by all the BALOs, while the others could only be lysed by some of the BALOs. However, differential lysis to some of the vibrios was also observed among BALOs within the same cluster. The four strains of different clusters all exhibited typical BALOs morphology, hav-ing vibrioid cell with a single polar flagellum.
