Objective To explore the relationship between echogenic intracardiac focus (EIF) and fetal heart defects.Methods Retrospective study of fetuses with EIF were performed at our fetal cardiac service centers from August 2010 to October 2015.Fetuses were grouped by EIF locations (left ventricle,right ventricle and biventricle).The risk of heart defect in different groups were analyzed.Results A total of 2 204 fetuses were enrolled in our study.Of them,2 083 EIF were located in the left ventricle,while 83 were bilateral and 38 were right-sided.There were 98 of 2 083 fetuses(4.7%) with heart defects in left-sided group,1 of 83 fetuses (1.2%) in bilateral group,and 5 of 38 fetuses(13.2%) in right-sided group.Fetuses with right-sided EIF had significantly more heart defects compared with the other two groups(P <0.05).Conclusions A right-sided EIF may carry a higher risk of cardiac anomalies than a left-sided or bilateral EIF.Women carrying fetuses with right-sided EIF should be offered fetal echocardiography in the second trimester.

Background and purpose:Drug resistance is a major cause of failure in lung cancer chemotherapy. This study aimed to investigate the effect of YAP on doxorubicin resistance in lung cancer and its underlying mechanism. Methods:Doxorubicin resistant lung cancer cell clones were established from parental sensitive cancer PC9 cell line via in vitroinduction, and the expression of YAP was analyzed. YAP was down-regulated via shRNA to different levels. MTS assay was employed to determine cell proliferation and drug sensitivity. Flow cytometry was used to determine cell cycle distribution, apoptosis and uptake of Rh-123. Western blot and quantitative real-time polymerase chain reaction (QRT-PCR) assay were used to determine the expression of ABCB1, ABCC1, p53, Runx2, ITGB2 and ErbB4. The phosphory-lation of serine/threonine kinase (AKT) was determined as well.Results:Doxorubicin resistant PC9/Adr cell clone was obtained with over-expressed YAP. Expression of YAP in PC9/Adr cells was down-regulated to different levels via shR-NA. After YAP silencing, cell proliferation was reduced, while sensitivity to doxorubicin was increased. The cell cycle was significantly halted by G0/G1 phase. Doxorubicin induced-apoptotic rate and cellular uptake of Rh-123 were increased,with positive correlation to YAP silencing level. Western blot and QRT-PCR results showed that after YAP silencing, ABCB1, ABCC1, Runx2, ITGB2, and ErbB4 proteins were down-regulated, while the expression of p53 was up-regulated. Phosphorylation of AKT was inhibited as well.Conclusion:Over-expression of YAP is involved in doxorubicin resistance in PC9/Adr cell line. Silencing of YAP could restore doxorubicin sensitivity. The mechanism involves regulation of drug resistance-related genes and promotion of apoptosis.

Objective To investigate the mitral annular three dimensional configuration changes after application of two dimensional mitral annuloplasty.Methods Includes criteria:serious mitral prolapse without other cardiac disorders,with age ranged from 18 to 60 years old.Three dimensional echocardiography was performed before the surgery in the operation room.The mitral annular three dimensional configuration,the mitral prolapse and regurgitation grades were examined.And same procedure was done after the mitral repair.All the measure results were expressed as x ± s and the statistical analysis was performed using SPSS 19.0 software.Results Totally 42 cases were enrolled,including 28 posterior prolapse and 14 anterior prolapse cases.All the mitral repair got satisfied none or mild regurgitation.The mitral annulus moved consistently as saddle shape during the whole cardiac cycle,the lowest annulus part was at the commissure and the highest part was at the anterior and posterior annulus centers.During the systolic phase the non-planer angel between anterior and posterior annuls was bigger than in diastolic phase.The annulus circumference,transverse,longitudinal diameters decreased compared with before the surgery.Preoperative mitral transverse diameter and longitudinal diameter values are almost the equal size,indicating the mitral annulus was in nearly round shape.However the longitudinal/transverse ratio reached 0.88 after surgery which implied the annulus configuration recovery after annuloplasty.After the mitral annuloplasty the annular height decreased from (8.4 ± 0.6) mm to (3.2 ±0.1) mm while the annular height/transverse diameter ratio decreased from 0.24 to 0.15,which may be affected by the application of the two dimensional rigid artificial annulus.Non-planar angle between the anterior and posterior mitral annuls increased from(136 ± 13)degrees to(145 ± 14) degrees after mitral repair.Conclusion The mitral annulus configuration may have planarization changes due 1o the apply of two dimentional artificial annulus.

Based on the known IRAK4 inhibitors MK-32 and AU-5,we designed and synthesized 12 pyridine-based target compounds by adopting open-ring and hybrid strategies,and combining molecular docking technology.The bioassays determined by radioisotope labeling demonstrated that the target compounds displayed good inhibitory activity against IRAK4.Among them,the IC50 value of 5 compounds was less than 1 μmol/L,suggesting that these compounds may be candidates for further investigation.
