Journal of Clinical Pediatrics 2014;(7):610-613
Objective To investigate the changes in bone age, and the correlation between the changes in structure and function of cardiovascular and bone age index in children with left to right shunt congenital heart disease (CHD) such as atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). Methods One hundred and thirty children diagnosed CHD had been enrolled, including 52 cases of ASD, 46 cases of VSD and 32 cases of PDA. The cardiac structure and function indicators had been detected by ultrasonic. The anteroposterior iflm of left hand and wrist had been taken. The bone age had been assessed according to“China children bone age score”atlas, and the bone age index (BAI) had been calculated. The differences of bone age among each group had been compared. The linear correlation of the cardiac structure and function indicators with BAI had been analyzed. Results The BAI was statistically different among ASD, VSD and PDA groups (P<0.05). The BAI of PDA group was higher than those of ASD and VSD groups (all P<0.05). The BAI was also statistically different among the groups with different pulmonary artery pressures (P=0.000). The BAI was higher in small defect size group than that in large defect size group (P=0.002). The defect size was negatively correlated with BAI in both ASD and VSD groups (r=-0.48, -0.54, all P<0.05), The pulmonary artery systolic pressure and pulmonary-to-systemic blood lfow ratio (QP/QS) were negatively correlated with BAI in ASD, VSD and PDA groups (r=-0.64--0.38,all P<0.05). Conclusion The bone age and BAI of children with left to right shunt CHD are signiifcantly lower than those of healthy children of the same age . The extent of bone age delay is related with PASP, defect size and shunt volume in children with left to right shunt CHD.

Objective To investigate the changes in physique and the bone age,and the correlation between the changes in cardiac structure and function and the bone age index (BAI) in atrial septal defect (ASD) children.Methods The experimental group included 48 cases of ASD patients,and 30 cases of healthy children were assigned as the control group;the children of both groups were measured for height and weight.Philips ie33 ultrasonic detector was used to detect the indicators of cardiac structure and function,and Philips digital X-ray machine was used to radiograph the left hand and the wrist.Then the bone age was assessed in order to calculate the BAI.Fourteen cases of ASD patients who underwent repairing surgery were measured for orifice area in surgery.The differences in physique and the bone age between the 2 groups were analyzed,and Pearson correlation analysis method was used to observe the correlation between the cardiac structure and function indicators,defect area and BAI in the experimental group.Results There was no significant difference in the age,height,bone age (t =-0.02,-1.31,-1.69,all P > 0.05),while the weight and BAI were significantly different between the 2 groups (t =-2.28,-9.06,all P < 0.05).The height,weight and BAI were significantly different in different pulmonary artery systolic pressure (PASP) patients (F =27.630,23.537,16.704,all P < 0.01),while the age and weight had no difference (t =-1.218,-0.046,all P > 0.05).The height and BAI were significantly different in patients with different defect size(t =2.561,2.191,all P < 0.05).There was no correlation between the age and the BAI in children with ASD(r =-0.175,P > 0.05).The defect size,defect size/atrial septal stretched diameter,PASP were all negatively correlated with BAI (r =-0.349,P < 0.05 ; r =-0.412,P <0.01 ;r =-0.539,P <0.01).The defect area was positively related to the defect size in 14 cases of children with ASD underwent surgery (r =0.599,P < 0.05),and the defect area was negatively correlated with BAI (r =-0.655,P < 0.05).Conclusions The physical development in ASD patients evidently lagged behind the healthy children,particularly for weight.The BAI of ASD patients is significantly smaller than that of the healthy children,in other words,the growing speed of bone in ASD patients is significantly slower than that of the healthy children at the same age.The lagging extent of physical development and the bone age are related to the PASP and defect size.PASP has more influence on the height,yet the defect size has influence on height and weight of ASD children.There is no correlation between physical development and the bone age with the course of disease.

Objective To investigate the therapeutic efficiency of intravenous implanted endothelial progeni-tor cells (EPCs) pretreated with stromal cell derived factor-1 (SDF-1) in rat model of acute myocardial infarction (AMI). Method The bone-marrow derived EPCs were cultured. The effects of SDF-1 on the migration and sur-rival of EPCs were evaluated in vitro. The rat models of AMI were produced and randomly divided into SDF-1 +EPCs group (n=12), EPCs group (n=12) and control group (n=12). EPCs pretreated with or without SDF-1 were infused via tail vein 24 hours after AMI modelled. The EBM-2 culture medium without cell was infuaed in control group. Vessel density, cardiac function and infarct area were measured on 14 days and 28 days after cell implantation. Results Fourteen days after cell implantation, the vessel density of SDF-1+EPCs group was higher than that of EPCs group and control group. Twenty-eight days after cell implantation, the cardiac function of SDF-1+EPCs group was better than that of EPCs group and control group. Conclusions EPCs pretreatment with SDF-1 can improve the survival and migratory capacity of EPCs, and increase the therapeutic efficiency for myocardial infarction.

OBJECTIVE:To study the improvement effect of Celosia cristata n-butanol extracts on dysfunctional uterine bleed-ing of rats,and explore its mechanism. METHODS:60 pregnant SD rats were randomly divided into blank group,model group, Gongxuening capsule group (positive control,0.07 g/kg) and C. cristata n-butanol extracts high-dose,medium-dose,low-dose groups(4.32,2.16,1.08 g/kg),10 in each group. Except for the blank group,rats in other groups were intragastrically given mife-pristone and misoprostol on 7th of pregnancy for resulting incomplete abortion to induce models of dysfunctional uterine bleeding. Then rats in administration groups were intragastrically given relevant medicines,rats in blank group and model group were intra-gastrically given normal saline once every morning and evening,for 7 d. On 8th d of pregnancy,uterine bleeding amount,and thromboxane (TXA2),prostacyclin (PGI2) and tumor necrosis factor α(TNF-α) contents in serum were determined. RESULTS:Compared with blank group,uterine bleeding amount in model group was significantly increased(P<0.01),TXA2 content in se-rum was significantly reduced,PGI2 and TNF-α contents were significantly increased(P<0.01). Compared with model group,uter-ine bleeding amounts in administration groups were significantly reduced,TXA2 content in serum was significantly increased(P<0.01);PGI2 and TNF-α contents in serum in Gongxuening capsule group and C. cristata n-butanol extracts high-dose group and TNF-α content in serum in C. cristata n-butanol extracts medium-dose group were significantly reduced (P<0.01). CONCLU-SIONS:C. cristata n-butanol extracts show obvious improvement effect on incomplete drug abortion-induced dysfunctional uterine bleeding of rats,and the mechanism may be related to the regulation of TXA2/PGI2 dynamic balance and inhibition of TNF-α tran-sient secretion.
