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.

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 explore the clinical significance of serum clara cell secretory protein(CC16),total immunoglobulin E(TIgE)and eosinophil cationic protein(ECP)in children with asthma.Methods Serum were collected from 59 cases during asthmatic acute attacks,29 asthmatic children who were in mild conditions,and 30 cases who were in moderate to severe conditions,and 30 healthy children.Serum CC16 concentration were measured by enzyme-linked immunosorbent assay(ELISA),TIgE and ECP concentration were measured by uniCAP100.Results The levels of CC16 in serum of asthmatic children during acute attacks were significantly lower than that in control group(t=2.93 Pa

Objective To investigate the risk factors of mild renal impairment in cerebral infarction patients.Methods One hundred and fifty patients with cerebral infarction were enrolled from June 2012 to June 2013,and all patients received cranial magnetic resonance imaging at the first week.The clinical data of patients were recorded in detail,24 h microalbuminuria (mALB) was detected,renal function was assessed.According to mALB,the patients were divided into normal renal function group (105 cases) and mild renal dysfunction group (45 cases).Clinical risk factors between 2 groups were compared,and multivariate regression analysis was done.Results Age in mild renal dysfunction group was greater than that in normal renal function group [(67.04 ±9.37) years vs.(63.01 ± 11.18) years],the incidence of hypertension and multiple lacunar infarction were higher than those in normal renal function group[57.8％ (26/45) vs.33.3％ (35/105),57.8％ (26/45) vs.22.9％ (24/105)],leukoaraiosis grade was higher than that in normal renal function group,there were significant differences (P ＜ 0.05 or ＜ 0.01).Logistic regression analysis found that hypertension (OR =1.04 1,P =0.045) and leukoaraiosis (OR =2.048,P =0.000) were independent risk factors for cerebral infarction patients with mild renal impairment.Conclusions The incidence of mild renal impairment is higher in cerebral infarction patients,and is closely related to hypertension and leukoariosis.Early detection of 24 h mALB in cerebral infarction patients has important clinical significance.

Objective To investigate the clinical value of serum iron(Fe),total iron binding capacity(TIBC),serum ferritin(SF), folic acid(FA)and vitamin 12(ViB12 )in the diagnosis and treatment of chronic renal failure(CRF).Methods Fasting blood sam-ples were collected from 72 patients with CRF and 83 normal controls.Then the serum SF,ViB12 and FA contents were measured by the ARCHITECT i2000SR fully automatic chemiluminescence immunoassay analyzer;serum Fe and TIBC were detected by the VITORS FS 5.1 dry biochemical analyzer;RBC,HGB,HCT and MCV were analyzed by the Mindray BC-6800 complete automated blood counter.The detection results were performed the statistical analysis by the SPSS16.0 software.Results The levels of TIBC,RBC,HGB and HCT in the CRF patients were significantly lower than those in the control group(P <0.05);while the SF and ViB12 levels were significantly higher than those in the control group;serum Fe and MCV had no statistical difference compared with the control group(P >0.05);the FA level in the female patients was lower than that in the control group,but which in the male patients had no statistical differences compared with the control group(P >0.05).Conclusion The indexes of anemia associat-ed metabolin in the CRF patients can provide certain reference value for the diagnosis and treatment of chronic renal fail and has cer-tain guidance significance for correcting anemia caused by renal insufficiency.
