Objective To study the risk factors of prolonged postoperative recovery after the total cavopulmonary connection(TCPC) in the current era.Methods Data on all patients admitted to the cardiac intensive care unit (CICU) after a TCPC between January 2013 and March 2014 were retrospectively analyzed.We excluded all patients who died and required TCPC takedown.The study cohort was further divided into a prolonged recovery group that included patients with 75％ ile for duration of mechanical ventilation or pleural drainage,and a standard recovery group which included all other patients.A multivariable logistic regression model was used to compare demographic,anatomic,and physiological variables between the prolonged and standard recovery groups.Then,the cohort was separated into a high volume resuscitation group and a low volume resuscitation based on the 75％ ile for volume resuscitation(ml/kg) administered on the first three days after the TCPC.Results Totally 118 TCPC operations were performed.Of the study population (n =118),the median age was 3.8 years (3.1 to 4.8 years) and median weight was 14.8 kg(13.3 to 17.1 kg).The most common diagnosis was double outlet of right ventricle (n =47,39.8％).The extracardiac conduit fenestrated TCPC was the most common surgery(n =79,66.9％).Within the study population,43 (39.8％) patients met criteria for prolonged recovery.Univariate risk factors for prolonged recovery included higher preoperative mPAP(P =0.022),atrioventricular valve regurgitation (P =0.000),longer total bypass time (P =0.044),higher postoperative central venous pressure (P =0.000),AST (P =0.001),ALT (P =0.010),NT-proBNP (P =0.000),SaO2 (P =0.012),I n-otropic score (P =0.001),higher incidence of arrhythmia (P =0.000),low cardiac output syndrome (P =0.000),need for peritoneal dialysis (P =0.000),and requirement for greater volume resuscitation during the 72 postoperative hours(75％ for the entire group,P =0.000).In a multivariable Logistic model,need for greater volume resuscitation (OR 10.860,95 ％ CI 2.681,43.987) and the higher postoperative central venous pressure (OR 1.446,95 ％ C I 1.113,1.879) were the only two independent risk factors for prolonged outcome after the TCPC.Conclusion The need for high volume expansion and higher central venous pressure were the risk factors of mediate prolonged recovery.

Objective To observe levels of the serum albumin and their association with prognosis in children with hand-foot-and-mouth disease (HFMD) . Methods A total of 122 HFMD children admitted from 2011 to 2013 were selected and divided into three groups:common group (n=57), severe group (n=52) and critical group (n=13). Serum albumin levels, blood glucose levels, peripheral blood white cell counts of the children in the three groups were compared within 24 hours of admis-sion. Moreover, the incidence of hypoalbuminemia and mortality of the children were analyzed in each group. Results In critical group, serum albumin levels were signiifcantly decreased while blood glucose levels and peripheral blood white cell counts were signiifcantly increased than those in the severe group and common group, and the differences were all statistically signiifcant (all P<0.05). There were no signiifcant differences in serum albumin levels, blood glucose levels and peripheral blood white cell counts between severe group and common group (all P>0.05). There was no hypoalbuminemia and death in severe group and common group. The percentage of hypoalbuminemia and mortality of children in critical group were higher than those in the other two groups (all P<0.01). Conclusions The mortality was extremely high in children with critical HFMD. The decrease of serum albumin levels was a high risk factor for death in children with critical HFMD. Early and dynamic monitoring serum albu-min levels may be helpful in evaluation of disease condition and prognosis of HFMD.

Objective To explore the differences in the expression of inhibin(INH)receptors and activin (ACT)receptors in the follicular/luteinic phase in normal human ovaries and their relationship with female endocrine hormone levels.Methods Real time PCR and immunohistochemistry were used to determine the expression of inhibin receptors(INHR)genes,activin receptors(ACTR)genes.Serum estradiol(E2),follicle stimulating hormone(FSH),luteinizing hormone(LH),INHB,ACTA levels were determined by a solid quantitative sandwich enzyme immunoassay technique(Sandwich ELISA)in 21 women during follicular phase and another 21 women during luteinic phase,the correlations between each gene and each hormone were analyzed.Results(1)ACT type Ⅰ and Ⅱ receptors genes(ACTR Ⅰ A,ACTR Ⅰ B,ACTRⅡA,ACTR Ⅱ B)and INH receptor β-glycan genes were expressed higher in the follicular phase than in the luteinic phase:ACTR Ⅰ A(0.50±0.17 vs 0.36±0.18;P＜0.05),ACTR Ⅰ B(0.050±0.019 vs0.036±0.020;P＜0.05),ACTRⅡ A(0.10±0.04 vs 0.07±0.04;P＜0.05),ACTR Ⅱ B(0.28±0.10vs 0.19±0.11;P＜0.05),β-glycan(0.26±0.10 vs 0.17±0.09;P＜0.01).(2)The intensities of ACTR I A,ACTR Ⅱ A,β-glycan immunostaining in human normal ovaries in the follicular phase were significantly stronger compared to those in luteinic phase.In the follicular phase β-glycan expression was positively correlated with serum E2,FSH,LH,INHB levels.The correlation coefficient was 0.53(P＜0.05).0.74(P＜0.01),0.85(P＜0.01)and 0.76(P＜0.01)respectively.Conclusion In normal human ovary in the follicular phase INH and ACT bind their receptors and down-regulate or up-regulate FSH,thus influencing the follicular development.

OBJECTIVE:To explore the effects of dobutamine on hemodynamics,tissue perfusion and respiratory function in patients with ARDS caused by septic shock. METHODS:Totally 26 patients with ARDS caused by septic shock were given Dobu-tamine hydrochloride injection 5 μg/(kg·min) by continuous pump for 20 min ,increasing by 5 μg/(kg·min) every 20 min to 15μg/(kg·min)for 6 h. Mean artery pressure(MAP)maintained at about 65 mmHg during continuous pump. Hemodynamic index-es [HR,MAP,cardiac output(CO),stroke volume(SV),total end diastolic volume(GEDV),intrathoracic blood volume index (ITBI),extravascular lung water index (ELWI),systemic vascular resistance index (SVRI)],tissue perfusion indexes (norepi-nephrine,urine volume,blood oxygen saturation,blood lactate)and ventilator parameter indexes(positive breathing pressure,min-ute ventilation volume,respiratory rate,peak inspiratory pressure and plateau pressure)of all patients were recorded before medica-tion,6,24,48 h after medication. RESULTS:There were no statistical significances in HR,MAP,GEDV,ITBI,blood oxygen saturation,blood lactate and respiratory rate before and after treatment (P>0.05). CO,SV,urine volume and minute ventilation volume of all patients 6,24,48 h after medication were significantly higher than before medication,and those indexes increased gradually as medication time. ELWI,SVRI,positive breathing pressure,peak inspiratory pressure and plateau pressure of all pa-tients after medication were significantly lower than before medication,and those indexes decreased gradually as medication time, with statistical significance(P<0.05). The levels of norepinephrine in all patients 24,48 h after medication were significantly low-er than before medication and 6 h after medication,with statistical significance(P<0.05);but there was no statistical significance between before medication and 6 h after medication(P>0.05). CONCLUSIONS:The early application of dobutamine ELWI,tis-sue perfusion and respiratory function in patients with ARDS caused by septic shock,and can keep hemodynamics stable.

Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P<0?01), 87?5% versus 68?75% (P>0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.
