Objective To prepare dual-targeted microbubbles carrying both anti-CD34 monoclonal antibody and anti-ICAM-1 monoclonal antibody,to identify its basic characteristics,and to investigate its targeting performance in vitro.Methods ICAM-1-targeted microbubbles (MgIcAM-1),CD34-targeted microbubbles(MBcD34) and dual-targeted (with both monoclonal antibodies) microbubbles (MBD) were prepared by biotin-avidin bridging chemistry method.The targeted microbubbles were observed under light microscrope and characterized by a Mastersizer 3000,DFY software,laser confocal microscopy,and flow cytometry.The targeting specificity and attachment capability of dual-targeted microbubbles to endothelial progenitor cells (EPCs) and damaged human umbilical vein endothelial cells (HUVECs) were assessed in vitro.Results The morphous,diameter,surface potential,concentration,and the antibody-binding rates of microbubbles were not statistically significant in MBIcAM-1,MBCD34,and MBD (P ＞0.05).Echo intensity in MBD significantly increased compared with MBICAM1,MBCD34,and MBiotin (P ＜ 0.01).The targeting experiment in vitro showed that the attachment rate of MBD to EPCs and damaged HUVECs significantly increased compared with MBiotin (P ＜0.01),while no remarkable difference in attachment rate was found between MBD and MBcD34 in EPCs,and between MBD and MBIcAM-1 in damaged HUVECs (P ＞0.05).Conclusions Dual-targeted microbubbles carrying both anti-CD34 monoclonal antibody and anti-ICAM-1 monoclonal antibody are prepared successfully.The study in vitro has proved that the dual-targeted microbubbles can specifically bind to both EPCs and damaged HUVECs.

Objective To investigate the protective effect of Shen Fu Injection (SFI) on cardiac function in sepsis rats and to explore the possible mechanism.Methods Forty SD male rats were randomly divided into 4 groups,namely normal control group,sham operation group,model group,SFI group.The sepsis model was established by cecal ligation and puncture (CLP).Thirty-six hours later,the arterial blood and left ventricular myocardium tissues were collected,and then the serum levels of tumor necrosis factor(TNF)-α and interleukin(IL)-1 were detected and the levels ofphosphorylated p38-mitogen-activated protein kinase (p-p38MAPK) and p38-mitogenactivated protein kinase (p38MAPK) in the supernatant of myocardial homogenate were detected.Results Thirty-six hours after modeling,left ventricular ejection fraction (LVEF) and left ventricular fractional shortening(LVFS) of the rats in the model group were significantly lower than those in the sham operation group (P ＜ 0.05).The heart function in SFI group was much improved compared with the model group (P ＜ 0.05).The serum TNF-α and IL-1 levels as well as p-p38/p38MAPK level in the supernatant of myocardial tissue of SFI group were lower than those in the model group (P ＜ 0.05).There were no significant differences of the above indexes between the sham operation group and the normal control group (P ＞ 0.05).Conclusion SFI has protective effect against sepsis myocardial injury.The mechanism may be related with the inhibition of p38MAPK phosphorylation in the myocardium,thereby reducing the release ofinflammatory cytokines in the pathway.

Background The incidence of dry eye is growing.However,the early diagnosis of dry eye is still difficult up to now.Keratograph 5M analyzer,a novel noninvasive ocular surface analyzer for dry eye may offer important parameters.Objective This study was to evaluate the clinical value of Keratograph 5M analyzer for clinical diagnosis of dry eye.Methods An observational study was proceeded with 88 cases who accepted myopia diagnosis in Tianjin Medical University Eye Hospital from October to December 2013.A series of conventional dry eye-related examinations were performed on the patients,including tear film break-up time (TBUT),corneal fluorescein staining scoring,Schirmer Ⅰ test (S Ⅰ t),and then Keratograph 5M analyzer-related examinations were subsequently carried out,including noninvasive tear film break-up time (NITBUT) and conjunctival hyperemia scoring.The correlations between conventional dry eye-related examinations and Keratograph 5M analyzer-related examinations were assessed by using Spearman rank correlation analysis.Results A total of 88 patients were recruited with male 32 and female 56.No significant difference in age was found between different genders (P =O.34).In 88 patients,Keratograph 5M analyzer showed the non-dry eyes in 15 patients,suspicious 44 patients (50.0％) and dry eyes in 29 patients (33.0％).However,the non-dry eyes were checked out in 39 patients and dry eyes were in 49 (55.7％) based on China Dry Eye Clinical Diagnosis and Treatment Consensus.The first NITBUT (NITBUTf) was less than the average NITBUT (NITBUTav) (P =0.00),and a positive correlation was seen between them (rs =0.62,P =0.00).Dry eye grade was significantly correlated with NITBUTf or NITBUTav or conjunctival hyperemia scoring (rs =-0.60,P =0.00 ; r,=-0.89,P =0.00 ; rs =0.24,P =0.02).A negative correlation was found between the conjunctival hyperemia scoring and NITBUTav (rs =-0.24,P =0.02).However,no significant correlation was seen between conjunctival hyperemia scoring and NITBUTf,TBUT,S Ⅰ t or corneal fluorescein staining scoring (rs=-0.13,P=0.22;rs=0.16,P=0.14;rs =-0.16,P=0.13;rs=-0.08,P=0.44).No significant difference was found between TBUT and NITBUTf (P =0.71).And TBUT was correlated with NITBUTf (rs =0.23,P =0.03),but not NITBUTav (rs =0.18,P =0.09).In addition,no significant correlations were seen between S Ⅰ t and NITBUTf or NITBUTav (rs=0.20,P=0.07;rs=0.05,P=0.66).Conclusions NITBUTav has an important significance in assessing overall ocular surface conditions.The conjunctival hyperemia score is one of refrent indicators to judge ocular surface status.
