Objective To summarize the clinical experiences of total cavopulmonary connection (TCPC), investigate the applications and short and mid term effects. Methods From 1999 to 2007,31 patients with complex congenital heart disease underwent TCPC. All patients were divided into child group(≤16 years old ,n =21 ) and a-dult group( n = 10 ), including 15 cases of functional univentricle, 8 cases of complete atrioventricular septal defect with double outlet of right ventricle, 3 cases of transposition with double outlet right ventricle, 3 cases of tricuspid atresia, 1 case of double outlet of right ventricle with hypoplastic left heart. 1 case of corrected transposition of the great arteries with TOF. Among them, 1 patient had cortriatriatum, 10 patients had left superior vena cave, moderate or severe mitral valve insufficiency occurred in 1, moderate atrioventricular valve insufficiency occurred in 3.28 pa-tients underwent TCPC with cardiopulmonary bypass ( CPB ) and 3 patients without CPB ;Of them, 21 patients were treated with extracardiac conduit and 10 cases with intratrial lateral tunnel. Results There was no early death,post-operative death or large quantities of pleural effusion in child group;but two deaths and three patients with large quantities of pleural effusion in adult group. One case caught up in inferior venous stasis and was cured. Follow- up was carded out from 6 months to 6 years. 26 patients were in NYHA class Ⅰ ,2 patients in NYHA class Ⅱ and only one patient in NYHA class Ⅲ. Conclusions TCPC is effectively used for complex congenital heart disease which can not be corrected in anatomy;serious postoperative complications often occur in adults. Atrioventricular valve in-sufficiency decisively affects the short and midterm effects, even the long-term effects.

Objective To study the brain protection of sequential double-sided antegrade cerebral perfusion to central nervous system in arotie arch surgery. Methods 24 patients received aortic arch replacement under deep hyperthermic circulatory arrest (DHCA) ,with fight-sided, and following double-sided, and left-sided,if necessary, antagrade cerebral perfnsion through right axillary arterial cannula or right femoral arterial eannula homeochronously. Post-operation recovery and the central nervous complications (CNC) were recorded and analyzed. Results 2 cases died, one of whom died of refractory low cardiac output syndrome and the other died of late massive gastrointestinal tract hemorrhage. No patient suffered severe CNC. Conclusion Sequential double-sided antegrade cerebral perfusion combined with DHCA can provide good brain protection in arotic arch replacement.

Objective To explore the impact of mindfulness on sleep and the mediating role of resilience.Methods A total of 540 medical staff in a three first-class hospital were assessed by five facet mindfulness questionnaire (FFMQ),Pittsburgh sleep quality index(PSQI) and Connor-Davidson resilience scale(CD-RISC).Results The average PSQI scores of medical staff was (6.67±3.20),of which the total score was equal or above 8 accounting for 37.04％.The positive rate of each factor of PSQI (factor score ≥2) was 51.67％ for daytime function,37.22％ for sleeping time,and 24.07％ for subjective sleep quality.The total score of PSQI was (6.67±3.20),the score of FFMQ was (119.55±9.90),and the score of CDRISC was (59.50± 12.77).PSQI was negatively correlated with FFMQ and CD-RISC (r=-0.29,-0.24;both P＜0.01),and there was a significant positive correlation between FFMQ and CD-RISC (r=0.48,P＜0.01).The factors of FFMQ associated with CD-RISC were followed by the description of mindfulness,the action of awareness,the non-reaction and the observation of mindfulness.The multi-linear regression analysis showed that resilience played a part mediating role between mindfulness and sleep quality,with a mediating effect of 20.9％.Conclusion Mindfulness has a positive impact on the quality of sleep of medical staff through resilience.

This paper presents a method for estimating three-dimensional (3D) motion of coronary arteries from single-plane X-ray angiogram sequences on two views. Firstly, original images are preprocessed and two-dimensional (2D) vessel skeletons are extracted. 2D motion estimation is performed along the skeletons in two images. Then geometrical transformation matrix between views is obtained based on perspective projection model for X-ray angiography system, and 3D coordinate of spatial points are calculated. The 3D motion estimation and reconstruction algorithm is applied along the two image sequences to accomplish 3D reconstruction of vessel skeletons and motion vectors between consecutive time instants. Its effectiveness has been demonstrated on clinical single-plane coronary artery angiograms and potential errors are discussed.

Objective To investigate value of peripheral NLR and PLR for the survival of patients with neuroblastoma.Methods The clinical data of 41 neuroblastoma patients were analyzed by the Kaplan-Meier,Log-rank test,and multivariate COX regression.Results NLR,PLR levels of neuroblastoma patients were significantly higher than that in the healthy control group (1.81 ±0.29 vs.1.07 ±0.29,P ＜ 0.01) (169 ± 23 vs.76 ± 3,P ＜ 0.01);The elder the age,the higher the clinical stages,the higher the serum levels of NSE,and urine VMA were,the higher was the NLR (x2 =3.93,6.286,7.676,6.689,all P＜0.05) and PLR (x2 =4.111,5.707,8.019,8.922,all P ＜0.05).The higher the serum level of LDH,the higher was the NLR (x2 =7.769,P =0.02).3-year overall survival in low NLR group was 84％ and that in high NLR group was 73％ (x2 =4.002,P =0.045);3-year progression-free survival in low NLR group was 74％ and that in high NLR group was 50％ (x2 =4.082,P =0.043);3-year progression-free survival of low PLR group was 85％ and high PLR group was 38％ (x2 =9.388,P =0.002).The clinical stages,MYCN genetic expression,NLR levels were independent factors for the overall survial in patients with neuroblastoma (P ＜ 0.05).Conclusion Pretreatment NLR level can effectively predict the prognosis of neuroblastoma.

Objective To explore the long?term efficacy of laparoscopic?assisted anorectoplasty and conventional anorectoplasty in the treatment of children with high and middle anal atresia. Methods A retrospective cohort study was used. Inclusion criteria: (1) children with high and middle anal atresia; (2) complicated with rectourethral or rectovesical fistula; (3) complete follow?up data. Exclusion criteria: (1) complicated with 21?trisomy; (2) cerebral palsy and other mentaldisabilities; (3) Currarino syndrome; (4) FG syndrome. Clinical data of 88 patients with middle and high anal atresia, who complicated with rectourethral fistula or rectovesical fistula, and underwent anoplasty at Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from January 2009 to June 2014 were enrolled in the study and analyzed. There were 24 cases with middle atresia and 64 cases with high atresia. All the cases were divided into 2 groups based on the operative method: laparoscopic group (laparoscopic?assisted anorectoplasty, 49 cases), pena group (posterior sagittal anorectoplasty, 39 cases). The demographic features of two groups were comparable. There were no statistically significant differences in gender, age, body mass, classification of anomaly types and sacral ratio (all P>0.05). Student t test and Chi square tests were used to compare the surgical conditions (operative time, postoperative hospital stay and complications), anal function (Kelly score), constipation (Krickenbeck constipation score) and anorectal pressure. Results Children of both groups all completed operation ssuccessfully. There were no statistically significant differences between laparoscopic group and pena group in the operative time [(120±31) minutes vs. (112±23) minutes, t=1.343, P=0.091] and postoperative hospital stay [(7.1±2.3) days vs. (10.7±3.3) days, t=6.021, P=1.000]. Complications were more common in the pena group [16.3% (8/49) vs. 35.9% (14/39), χ2=4.436, P=0.035]. The main complications in laparoscopic group were anal prolapse (8.2%, 4/49) and anal stenosis (6.2%, 3/49), while in pena group were anal stenosis (12.8%, 5/39) and perioperative perianal skin erosion (10.3%, 4/39). As for the anal function, the degree of feces, defecation control and sphincter contractility, the single scoring differences of Kelly scoring system were not statistically significant between the two groups, but the proportion of good function in the laparoscopic group was higher than that in the pena group [67.3% (8/49) vs. 38.5% (15/39), χ2=7.308, P=0.007]. Constipation occurred in 6 (12.2%) patients in the laparoscopic group, of whom 5 were improved by diet regulation and 1 required laxatives, while 9 (23.1%) patients developed constipation in the pena group, of whom 4 were improved by diet regulation and 5 required long?term laxatives. The difference of constipation ratio was not statistically significant (χ2=1.802, P=0.180). There were no cases of Krickenbeck constipation grade 3. Compared to the pena group, the laparoscopic group had higher anal resting pressure [(33.35 ± 9.69) mmHg vs. (27.68 ± 10.74) mmHg, t=2.599, P=0.011], higher dilating pressure [(9.00±5.61) mmHg vs.(6.51±3.24) mmHg, t=2.462, P=0.016], higher maximal squeeze pressure [(65.80 ± 17.23) mmHg vs. (56.74 ± 18.93) mmHg, t=2.389, P=0.019] and longer maximal contraction time [(21.16±5.02) seconds vs. (18.44±7.24) seconds, t=2.079, P=0.041]. The rectal resting pressure [(5.36 ± 3.00) mmHg vs. (4.61 ± 3.93) mmHg, t=1.015, P=0.312] was not statistically significantly different. Conclusions Compared with posterior sagittal anorectoplasty, laparoscopic?assisted anorectoplasty in the treatment of high and middle anal atresia has better long?term efficacy with less perioperative complications.
