50 days),whereas third party skin grafts were vigorously rejected.Conclusion Blockade of CD28-B7 and CD40-CD40 ligand interactions resulted in long-term allograft survival and donor-specific tolerance in mouse cardiac transplantation without chronic rejection.

OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92％) was higher than that of male patients (39.14％). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33％),skin and its appen-dants (411 cases,20.78％) and others (305 cases,15.42％). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46％ of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.

Objective To evaluate the changes of the waveform of the photopic negative response in flash-electroretinogram, visual acuity and central retinal thickness in the treatment of intravitreal injections of bevacizumub. Design Retrospective self-comparative case series. Partidpants 8 subjects (9 eyes) with exudative age-related macular degeneration and 3 subjects (3eyes) with proliferative diabetic retinopathy. Method Evaluation protocol included examinations of the Early Treatment Diabetic Retinopathy study visual acu-ity, visual field, intraocular pressure, fundus fluorescein angiography, optical coherence tomography and flash-electroretinogram. Intravit-real injections of bevacizumab, 1.25 mg (0.05ml), were given under an operating microscope and aseptic conditions. All the subjects were followed-up one month later. Main outcome Measure The amplitudes of PhNR, visual acuity and central retinal thickness. Re-sult At 1 months, the mean amplitudes of PhNR and mean visual acuity in all cases had no obvious change (n=12, P>0.05).The central retinal thickness reduced obviously (n=12, P<0.05), but it was neither significantly correlated with PhNR (r=0.294, P=0.145) nor with visual acuity(r=-0.358, P=0.073). Conclusion The single intravitreal injection of bevacizumab is showed promising in absorption of in-traretinal edema and subretinal fluid in patients with exudative age-related macular degeneration and proliferative diabetic retinopathy, but the changes of visual function (including PhNR) might need further investigation.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.

AIM: To investigate the effect of ischemia induced by central retinal artery occlusion on retinal microstructure of macula using optical coherence tomography (OCT). METHODS: Fourteen eyes of 14 patients with unilateral central retinal artery occlusion (CRAO) in two to three days without fully recovery of retinal circulation underwent OCT examination with 4.5 mm length horizontal and vertical line scans through foveola to measure the retinal neurosensory layer (RNL) thickness on foveola, 175 ?m (fovea), 750 ?m (macula) to foveola, respectively. The other normal eyes of patients as control group underwent the same examination and measurement. RESULTS: The mean RNL thickness(?m) on foveola, fovea, macula were 169 91?10 96, 176 36?11 74 and 256 45?16 95 respectively in normal control eyes, and 235 64?47 02 , 241 84?49 36 and 401 57?54 53 respectively in CRAO eyes with retinal ischemia. There was a significant difference in thickness between two group ( P

Background Previous studies showed that after herpes simplex virus-1 (HSV-1) infection of the cornea,matrix metallo proteinase-2 (MMP-2) (produced by corneal cells and corneal epithelial cells) plays an important role in the development of HSK.Focal adhesion kinase (FAK)plays an important role on the expression,release and activation of MMPs.This study explored the expressions of MMP-2 and FAK,which induced by HSV-1 infected human corneal epithelial cells.Objective To investigate MMP-2 and FAK expression in HSV-1 infected human corneal epithelial cells.Methods Human corneal epithelial cells were infected with HSV-1 in vitro to establish cell model of viral infection.The expression of MMP-2 and FAK were detected by reverse transcription PCR (RT-PCR),Western blot,immunohistochemical method and immunofluorescence method at 2 hours,20 hours and 40 hours after infection.Results At 2 hours,20 hours and 40 hours after infection,the expressionis of MMP-2 mRNA and FAK mRNA were significantly increased in comparison with uninfected cells (MMP-2 mRNA:Ftime =0.968,P=0.436 ; Fgroup =47.649,P =0.000 ; Fi ion =0.757,P =0.536.FAK mRNA:Ftime =0.658,P =0.631 ; Fgroup =35.182,P=0.000;Finteraction =1.386,P=0.137).Western blot assays showed that there were no significant differences in p-FAK,FAK or MMP-2 expressions between infected cells and control cells after 2 hours (P＞0.05),but the expression levels of infected cells were significantly increased at 20 hours and 40 hours (both at P ＜ 0.05).Immunohistochemistry results showed that longer infection time was associated with an increased number of cells staining for MMP-2,FAK and p-FAK.Conclusions At the initial stage of HSV-1 infected,p-FAK plays an important role in the process of virus invading and MMP-2 activation.
