Objective To analyze the prognosis of patients with pulmonary artery sling (PAS) combined with tracheal stenosis(TS) without tracheal intervention,and to discuss the method for improving the effect of treatment.Methods The clinical data of 17 children with PAS/TS (moderate or severe) who received treatment at Beijing Bayi Children's Hospital Affiliated to General Hospital of Bejing Military Command from October 2011 to July 2015 were retrospectively analyzed,and the relationship between the effect and prognosis of re-implantation of the left pulmonary artery (LPA) without tracheal intervention was analyzed.Results Seventeen patients received re-implantation of the left pulmonary artery without tracheal intervention.Extubation was successfully performed in 12 of the 17 patients and they healed.The remaining 5 patients received tracheal intervention after the first operation but they all died.Of those 5 patients,3 received tracheal stent implantation (1 died from necrotizing enterocolitis,2 died from infection and multiple organ failure),and 2 received traheoplasty (both of them died from infection and tracheal fistula).Respiratory symptoms were reduced or resolved in all survivors.Diameter/length (％) in survivors without tracheal intervention was significantly higher than those who received tracheal intervention [(10.14 ± 1.58) ％ vs.(5.72 ± 1.17) ％,t =3.600,P ＜ 0.001].Patients with PAS undergoing LPA re-implantation achieved a good outcome if the diameter/length(％) of the trachea was up to (10.14 ± 1.58) ％.Patients with PAS undergoing LPA re-implantation achieved a bad outcome if the diameter/length(％) of the trachea was below to (5.72 ± 1.17) ％.Conclusions Most of patients with PAS/TS undergoing LPA re-implantation without tracheal intervention have a good outcome.It is feasible for them to avoid tracheal intervention.Diameter/length (％) may be a reliable indicator for determining tracheal intervention in surgical management of PAS.

Objective To evaluate the effectiveness of urgent surgical correction for infra-cardiac total anomalous pulmonary venous connection(TAPVC)in neonates.Methods From October 2009 to Janu-ary 2015,13 patients with infra-cardiac TAPVC received surgical correction.The age of patients ranged from 6 to 28 days[(15.08 ±7.42)days],the body weight ranged from 2.5 to 4.8 kg [(3.34 ±0.67)kg].A median sternotomy was performed.Continuous cardiopulmonary bypass using bicaval cannulation with aortic cross-clamping and mild systemic hypothermia were used in all patients.Bi-atrial incision technique making anastomosis between the posterior left atrial wall and the vertical vein were employed in 3 cases.In the other 10 cases,the heart was elevated upward and to the right to expose the anomalous descending vertical vein to facilitate the anastomosis between the posterolateral left atrial wall and vertical vein.Results Emergent or subemergent operations were performed in all patients without surgical death.In the early stage after opera-tion,delayed sternal closure was employed in 1 1 patients,pulmonary hypertension crisis occurred in 3 pa-tients,small atrial septal defect was kept open for hemodynamic stabilization in 6 patients,temporary cardiac pacemaker for proper heart rate in 3 patients.All patients were uneventfully discharged except 2 patients died of severe low cardiac output syndrome.During the period of follow up,2 patients presented with recurrent pulmonary infection and signs of pulmonary venous obstruction including the increased flow speed at the site of anastomosis.One of 2 patients was lost of follow up and the other patient was uneventfully discharged after the second operation.The rest 9 patients received postoperative follow up for 1 month to 5 years,echocardio-graphy,X ray chest radiography,and electrocardiogram were performed during this period.As a result,all children had good cardiac function and with sinus rhythm on electrocardiogram and apparently reduced pul-monary congestion on radiography.No obstructive pulmonary venous return was observed on echocardio-graphy.Conclusion Corrective operation for infra-cardiac TAPVC in neonate on urgent basis may provide favorite outcomes.

Objective:To investigate changes in serum C3d and C5b-9 levels in elderly patients with idiopathic membranous nephropathy(IMN)and their correlations with prognosis.Methods:Two hundred thirty-one elderly patients with IMN and 96 non-elderly patients with IMN confirmed by kidney biopsy at the First Affiliated Hospital of Zhengzhou University from January 2015 to May 2017 were enrolled.During the same period, 118 healthy individuals receiving health checkups were included as controls.Patients were divided into the low C3d group( n=112)and the high C3d group( n=113)according to the median level of serum C3d.Serum C3d and C5b-9 levels were measured by enzyme-linked immunosorbent assays. Results:Serum C3d and C5b-9 levels in elderly IMN patients were 0.23(0.15, 0.45)mg/L and 0.28(0.20, 1.23)mg/L, respectively, which were higher than those in healthy controls[0.18(0.13, 0.22)mg/L, 0.22(0.16, 0.26)mg/L, respectively]( Z=-4.261 and -6.213, P<0.001). Serum C3d levels in elderly and non-elderly IMN patients were correlated negatively with the estimated glomerular filtration rate( r=-0.155 and -0.426, P=0.019 and 0.000), but positively with serum creatinine, anti-phospholipase A2 receptor(PLA2R)antibody levels and 24 h urinary protein( r=0.184, 0.326, 0.407, 0.321 and 0.145, P=0.005, 0.001, 0.000, 0.001 and 0.027). Kaplan-Meier survival analysis showed that the cumulative renal survival rate in elderly IMN patients was lower in the high C3d group than in the low C3d group(47.8% vs.70.8%, Log Rank χ2=7.399, P=0.007). Multivariate Cox regression analysis showed that high C3d levels were an independent risk factor for poor renal outcomes in elderly IMN patients( HR=2.288, 95% CI: 1.082-4.839, P=0.030). Conclusions:High serum C3d levels are associated with increases in urinary protein excretion and anti-PLA2R antibody levels, renal function decline, and poor renal outcomes in elderly IMN patients.

Objective:To detect serum level of complement factor B (CFB), and to explore its correlations with clinical parameters and prognosis in children with primary IgA nephropathy (IgAN).Methods:A total of 204 children with primary IgAN confirmed by kidney biopsy in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from December 2014 to April 2017 were included in IgAN group.During the same period, 84 healthy children were included in healthy control group.Their mean age was (11.0±3.5) years and (10.9±3.2) years, respectively.Patients in IgAN group were divided into low CFB group (102 cases) and high CFB group (102 cases) according to the medium serum level of CFB measured by enzyme-linked immunosorbent assay. Spearman′ s coefficient was employed to analyze correlation amongst various parameters.Multivariable-adjusted Cox proportional ha-zards models were used to evaluate the relationship between serum CFB level and prognosis in children with IgAN. Results:Serum CFB levels were significantly higher in IgAN group than that in healthy control group [290.9 (186.2-453.9) mg/L vs.218.9 (155.0-321.3) mg/L, Z=-3.372, P=0.001]. Serum levels of CFB were negatively correlated with serum albumin ( r=-0.388, P<0.001) and estimated glomerular filtration rate ( r=-0.416, P<0.001), but positively correlated with serum creatinine ( r=0.305, P<0.001) and 24 h urinary protein ( r=0.456, P<0.001) in IgAN group.The incidences of crescents (C1-2) (70.6% vs.29.4%, χ2=34.588, P<0.001) and C 3 deposition (+ + -+ + + ) (63.7% vs.44.1%, χ2=7.892, P=0.005) were significantly higher in high CFB group than those in low CFB group. Kaplan- Meier analysis showed that high CFB levels predicted worse renal outcome in pediatric IgAN patients ( χ2=17.509, P<0.001). Multivariate Cox regression analysis showed that the high CFB level was the independent risk factor for the poor renal outcome ( HR=2.517, 95% CI: 1.284-4.932, P=0.007). Conclusions:High serum levels of CFB are associated with decreased renal function, increased urinary protein excretion, crescentic formation and poor renal outcome in pediatric IgAN patients.

Objective: To investigate the feasibility of molecular diagnostic techniques to guide individualized treatment of lung cancer. Methods:A total of 360 patients with lung cancer confirmed by pathological diagnosis received clinical chemotherapy from Jan 2011 to Dec 2013 were selected as the experimental group who chose chemotherapy drugs for drug?sensitive individualized treat?ment based on molecular diagnostic technology test results. Another 180 patients with lung cancer were selected as the control group who did not carry out individual testing only chose conventional chemotherapy. The efficacy and side effects of drugs were assessed. The progression?free survival and median survival time were followed and recorded, and the survival curve was drawn by the Kaplan?Meier method. Results: There was significant difference in the efficacy between the two groups ( P<0?05) , and there was no signifi?cant difference in side effects of drugs. The progression?free survival time and median survival time were significantly different ( P<0?01) . Conclusions: Molecular diagnostic techniques to guide individual treatment of lung cancer have some clinical significance, it will help to improve the efficacy and worthy of further study.
