Objective To investigate the effect of sodium citrate on the efficacy of oral midazolam premedication in children with congenital heart disease. Methods Forty ASA Ⅱ or Ⅲ children, aged 2-6 yr, weighing 12-20 kg, undergoing cardiac surgery, were randomly divided into 2 groups (n = 20 each): control group (gronp C) and sodium citrate group (group S). Group S received oral mixture of midazolam 0.12 ml/kg (0.6 my/kg), ketamine 0.12 ml/kg (6 my/kg), glucose 0.12 ml/kg (60 mg/kg) and sodium citrate 0.12 ml/kg (3 mg/kg), total volume 0.48 ml/kg. Group C received oral mixture of midazolam 0.12 ml/kg, ketamine 0.12 ml/kg and glucose 0.24 ml/kg, total volume 0.48 ml/kg. Hydrochloric acid (pH value 1.75) was mixed with the mixtures in the two groups and pH values were measured. Preoperative anxiety scale and the onset time,sedation score and parental separation score after receiving oral drugs were recorded in preparation room for anesthesia. After entering the operating room, HR, MAP and SpO2 were monitored, and the response to venepuncture in children and the adverse effects associated with oral drugs were also observed and recorded. Results The pH value was 1.97 in group C and 4.52 in group S. The parental separation score, sedation score and response score were significantly lower and the onset time was significantly shorter in group S than in group C. HR, MAP and SpO2 were in the normal range after entering the operating room. There was no obvious adverse effect after administration of oral drugs in the two groups. Conclusion Application of sodium citrate in the oral premedication in children with congenital heart disease can raise the pH value, shorten the onset time of midazolam, and enhance the sedative efficacy.

Objective To assess the relationship between arterial stiffness and heart function in patients with hypertension using ultrasonography. Methods A total of 167 patients with hypertension and 165 controls were enrolled, and the parameters of arterial stiffness and heart function were measured and calculated. The results were analyzed and compared. Results The ratio of peak early-diastolic mitral orifice flow velocity and peak early-diastolic mitral annular velocity in left ventricular posterior wall (E/e), and Tei index were significantly higher in hypertension group than in controls(E/e: 10.92±3.14 vs. 7.70 ±1.56, Teiindex: 0.58±0.13 vs. 0.45±0.09, both P<0.05), but there was no significant difference in ejection fraction (EF) between the two groups. In hypertension group, the parameters of arterial stiffness including β value, pressure-strain elastic modulus (Ep), pulse wave velocity (PWVβ) and arterial compliance were 11.0±5.2, (172.6±83.8)kPa, (7.8±1.6) m/s and (0.6±0.2) mm2/ kPa. In control group, the corresponding data were 7.5±3.0, (97.1±45.4) kPa, (5.9±1.3) m/s and (0.8±0.3) mm2/kPa. There were significant differences between the two groups (all P<0.05). The E/e was positively correlated with Ep and PWVβ(γ=0.316 and 0.296, both P<0.05). The Tei index was positively correlated with Ep,augmentation index (AI) and PWVβ(γ=0.278, 0.300 and 0.323, P<0.05-0.01). There was no significant correlation between EF and arterial stiffness. Conclusions The arterial stiffness and damage of heart function can result from hypertension. The arterial stiffness can be one of monitoring indexes for the heart function damage in early time.

Objective Several studies have indicated that miR-15a,miR-15b and miR-16 may be the important regulators of apoptosis.Since attenuate apoptosis could protect myocardium and reduce infarction size,the present study was aimed to find out whether these miRNAs participate in regulating myocardial ischemia reperfusion (I/R) injury.Methods Apoptosis in mice hearts subjected to I/R was detected by TUNEL assay in vivo,while flow cytometry analysis followed by Annexin V/PI double stain in vitro was used to detect apoptosis in cultured cardiomyocytes which were subjected to hypoxia/reoxygenation (H/R).Taqman real-time quantitative PCR was used to confirm whether miR-15a/15b/16 were involved in the regulation of cardiac I/R and H/R.Results Compared to those of the controls,I/R or H/R induced apoptosis of cardiomyocytes was significantly iucreased both in vivo (24.4% ± 9.4% vs.2.2% ± 1.9%,P < 0.01,n =5) and in vitro (14.12% ±0.92% vs.2.22% ± 0.08%).The expression of miR-15a and miR-15b,but not miR-16,was increased in the mice I/R model,and the results were consistent in the H/R model.Conclusions Our data indicate miR-15 and miR-15b are up-regulated in response to cardiac I/R injury,therefore,down-regulation of miR- 15a/b may be a promising strategy to reduce myocardial apoptosis induced by cardiac I/R injury.
