Recent advances of age-related maculopathy susceptibility 2 / 中华实验眼科杂志

The prevalence of age-related macular degeneration (AMD) is increasing yearly,and AMD has become the first cause of elderly vision irreversible loss.In China,an aging society is developing,so the prevention and therapy for AMD is faced with a new challenge.Thc multi-faceted study on AMD has become a focus of fundus disease in ophthalmology.AMD is thought to be a multifactorial-induced disease,and it is closely related to age,genetic and environmental factors.But its pathogenesis is not understood enough up to now.In recent years,epidemiological study revealed that the chromosome 10q26 has multiple polymorphic loci.Age-related maculopathy susceptibility 2 ( ARMS2,rs10490924 ) is reported to be a major risk factor of AMD in the yellow race.In this paper,the ARMS2 gene epidemiology,cell positioning and related treatment were reviewed.

Expression and location of ARMS2 protein in normal eye tissue / 中华实验眼科杂志

Background Researches determined that the alteration of A69S locus of age-related maculopathy susceptibility 2 ( ARMS2 ) gene is closely associated with the pathogenesis and progression of age-related maculopathy ( AM D ).However,the location of ARMS2 protein in normal eye tissue is still in controversy,therefore,its function is below understanding up to now.Objective The goal of this laboratory work was to investigate the distribution,expression and location of ARMS2 protein in normal adult retina and choroid as well as in retinal pigment epithelial (RPE) cells and lay a basis for exploring further its function in the protein level.Methods Ten donor eyeballs of normal adult male with the age from 28-42 years were collected in eye bank of Qingdao Eye Hospital.The frozen sections of the retina and choroid were prepared for the detection and location of ARMS2 in 3 eyes by immunofluorescence under the confocal laser microscope.The retina was isolated for the primary culture of RPE cells using explant culture method.The cells were then identified by CK32 antibody by immunofluorescence.The distribution and expression of the ARMS2 protein in retina,ehoroid and RPE cells were determined by immunofluorescence technique.Results ARMS2 protein was strongly expressed in retinal vessel,RPE cell layer,Bruch membrane and choroidal vessel,but weak expression was in retinal ganglion cell layer,inner nuclear layer,outer plexiform layer,outer nuclear layer and inner plexiform layer in the normal eyes.The primarily cultured cells appeared the polygon shape with the abundant pigment in cytoplasm.The immunofluorescence of the cells showed the positive response for CK32,exhibiting the green fluorescence granules in the cytoplasm.The positive expression of ARMS2 protein also was seen in the cytoplasm of RPE cells,appearing the red fluorescence.Conclusions ARMS2 protein mainly distribute and locate retinal and choroidal vessels,RPE cells and Bruch membrane in normal eye.

Oral propranolol in the management of periorbital proliferating phase infantile hemangioma / 中华整形外科杂志

<p><b>OBJECTIVE</b>To observe the efficacy and safety of oral propranolol in the treatment of periorbital proliferating phase infantile hemangioma.</p><p><b>METHODS</b>A retrospective review of patient medical records was performed. 12 patients (9 female, 3 male; 1.5-8.5 months, average 3.3 months) with periorbital proliferating phase infantile hemangioma underwent oral propranolol therapy. The dosage was slowly increased to 2 mg/kg daily in divided doses for a mean duration of 16 weeks (range 4 weeks-41 weeks). Therapeutic outcomes and safety were established by evaluating colour, size of lesion, duration of treatment and side-effects of treatment before and after treatment.</p><p><b>RESULTS</b>Of these, 9 had a signification reduction in colour and size of the lesions, 2 had no further growth. 1 is stopped therapy due to hypotension after drug administration. 11 other patients, although mild adverse effects were noted, no symptoms were severe enough to discontinue treatment.</p><p><b>CONCLUSIONS</b>Propranolol appears to be a safe and effective treatment in the management of periorbital proliferating phase infantile hemangioma.</p>

The change of serum vascular endothelial growth factor and matrix metalloproteinases-9 in proliferative hemangioma treated with propranolol / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the level of serum vascular endothelial growth factor, matrix metalloproteinases-9 in the proliferative hemangioma before and after propranolol treatment.</p><p><b>METHODS</b>The serum VEGF, MMP-9 was detected with ELISA assay before treatment and after 4 weeks and 8 weeks of propranolol treatment. The relationship between the serum VEGF, MMP-9 and the prognosis was analyzed.</p><p><b>RESULTS</b>The serum VEGF (295.4 +/- 158.1) pg/ml was high before treatment, then decreased after 4 weeks and 8 weeks of treatment (255.7 +/- 130.4) pg/ml, (224.2 +/- 120.6) pg/ml. The serum VEGF was significantly lower after 8 weeks of treatment (P < 0.05). The serum MMP-9 was also decreased after treatment, showing a positive relationship with VEGF.</p><p><b>CONCLUSIONS</b>Propranolol can treat the proliferative hemangioma through decreasing the serum VEGF and MMP-9.</p>

Effect of compound glycyrrhizin injection on liver function and cellular immunity of children with infectious mononucleosis complicated liver impairment / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the effects of Compound Glycyrrhizin Injection (CGI) on liver function and cellular immunity of children with infectious mononucleosis complicated liver impairment (IM-LI) and to explore its clinical therapeutic effect.</p><p><b>METHODS</b>Forty-two patients with IM-LI were randomly assigned, according to the randomizing number table, to two groups, 20 in the control group and 22 in the treated group. All the patients were treated with conventional treatment, but to those in the treated group, CGI was given additionally once a day, at the dosage of 10 ml for children aged below 2 years, 20 ml for 2-4 years old, 30 ml for 5-7 years old and 40 ml for 8- 12 years old, in 100-200 ml of 5% glucose solution by intravenous dripping. The treatment lasted for 2 weeks. T lymphocyte subsets and serum levels of alanine transaminase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBil) were detected before and after treatment. Besides, a normal control group consisting of 20 healthy children was also set up.</p><p><b>RESULTS</b>Baseline of the percentage of CD3 + , CD8 + lymphocyte and serum levels of ALT, AST, TBiL in the children with IM-LI were markedly higher, while the percentage of CD4 + lymphocyte and the CD4 + /CD8 + ratio was markedly lower in IM-LI children as compared with the corresponding indices in the healthy children ( P<0.01). These indices were improved after treatment in both groups of patients, but the improvement in the treated group was better than that in the control group (P<0.01).</p><p><b>CONCLUSION</b>Cellular immunity dysfunction often occurs in patients with IM-LI, and CGI treatment can not only obviously promote the recovery of liver function, but also regulate the immune function in organism.</p>
