Objective To investigate the clinical characteristics of incomplete Kawasaki disease(KD).Methods Clinical data includi-ng test results,therapeutic methods were analyzed retrospectively in 579 patients with Kawasaki disease.They were divided into classic KD and incomplete KD and made a compared analysis.Results There were no significant differences in gender,age,symptom and laboratory examination between classic and incomplete KD.But the rate of coronary artery lesions was higher in incomplete KD(18.4%) than that of classic KD(11%).Conclusion The rate of coronary artery lesions was higher in incomplete KD,and it should be paid more attention to earlier diagnosis and earlier treatment.

Objective To investigate the effect of Wnt5a on inducing differentiation of Cp15-5a cell to myocardial cell.Methods Recombinant adenovirus wnt5a (Ad-wnt5a) and Ad-GFP was amplified with human embryo kidney 293 cells (HEK293 cells),and then transfected into CP15-5a cells and 3 experiment groups were set up:wnt5a group,GFP group and blank control group.Flow cytometry was used to detect the transfection efficiency of Ad-wnt5a and Ad-GFP.One week after transfection,the expressions of genes GATA binding protein 4 (GATA4) and myocardial enhancement factor 2C (MEF2C) were analyzed by realtime quantitative PCR (qRT-PCR).Two weeks after transfection,the expressions of cardiac-specific connexin 43 (Cx43) and cardiac troponin T (cTnT) in Ad-wnt5a-induced CP15-5a cells were detected by Western blotting and immunofluorescence techniques.The sodium current expression (INa) was detected by whole cell patch clamp techniques.Results The transfection efficiency of Ad-wnt5a and Ad-GFP was 42.8% and 44.3%,respectively.One week after transduction,the expressions of GATA4 and MEF2C were significantly higher in wnt5a group (1.717 ± 0.220 and 1.847 ± 0.190) than in GFP group (1.003 ± 0.087 and 0.456 ± 0.042,P<0.05) and blank control group (0.961 ± 0.063 and 0.500 ± 0.095,P<0.05),while no significant difference existed between GFP group and blank control group.Two weeks after transduction,the expressions of CX43 and cTnT were significantly higher in wnt5a group (1.597 ± 0.267 and 0.727 ± 0.100) than in GFP group (0.723 ± 0.047 and 0.217 ± 0.021,P<0.05) and blank control group (0.783 ± 0.1333 and 0.253 ± 0.102,P<0.01),while no significant difference existed between GFP group and blank control group.INa was detected in the wnt5a group compared with GFP group and blank control group.Conclusion wnt5a may induce differentiation of cp 15-5a cell into myocardial cell.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.
METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).
RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).
CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
