Objective To explore risk factors related to acute kidney injury (AKI) in children who underwent corrective surgery for tetralogy of Fallot (TOF). Methods We retrospectively analyzed the clinical data of 726 children with corrective procedures for TOF aged less than 3 years in our hospital from March 1st 2010 to March 1st 2013. Children with AKI were picked using Acute Kidney Injury Network criteria. Demographic and perioperative variables of the remaining patients were reviewed. Univariate analysis was performed to compare the AKI group (240 patients) with the non-AKI group (486 patients). Multivariable analysis was carried out to identify significant determinants of AKI. Results A total of 240 children were with AKI. The result of univariate analysis showed that there was a statistical difference in age, Nakata index, McGoon ratio, left ventricular end-diastolic volume index (LVEDVI), transannular right ventricular outflow tract (RVOT) patch, or fresh frozen plasma (FFP) in prime solution between the AKI group and the non-AKI group. Multivariable logistic regression showed that in older children (OR=1.425, 95% CI 1.071 to 1.983, P=0.011) with more transfusion of FFP in the priming solution (OR=1.486, 95% CI 1.325 to 2.674, P<0.001) led to higher morbidity of mild AKI. In addition, there was an increase in morbidity related to AKI when children had less Nakata index (OR=0.282, 95% CI 0.092 to 0.869, P=0.013). Conclusion Postoperative AKI increases in older children group. Infusion of more FFP in priming solution increases morbidity of AKI. The less Nakata index is significantly associated with severe AKI.
The success of staged Fontan palliation for patients with single ventricle is related to low pulmonary vascular resistance (PVR). The complications of high PVR in Fontan physiology are numerous, such as low exercise tolerance, low cardiac output, ventricular function failure and protein-losing enteropathy; eventually it leads to failing Fontan. Therefore, a low PVR is crucial in Fontan patients. Now, targeted therapies decreasing PVR has been an advanced research hotspot in Fontan patients. In this review we present an overview of the safety and efficacy of the therapy with bosentan or sildenafil on elevated pulmonary artery pressure and pulmonary vascular resistance in Fontan patients.
Objective To study the expression of inducible nitric oxide synthase (iNOS)，endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) in human gastric cancer and their relationship with tumor angiogenesis and to investigate the interaction of NOS and VEGF in gastric cancer. Methods The expression and distribution of VEGF, iNOS and eNOS in 34 gastric cancer specimens were detected with immunohistochemistry. Microvessel density (MVD) was counted with FⅧRAg immune specific staining. Results The expression rates of iNOS, eNOS and VEGF in 34 gastric cancers were 73.5%, 82.4% and 91.2% respectively. The expression of VEGF had a significant positive relation with iNOS, but not with eNOS. The MVDs of VEGF or iNOS positive gastric cancers were obviously higher than those of VEGF or iNOS negative gastric cancers. There was no significant difference between the MVDs of eNOS positive gastric cancers and eNOS negative ones. Conclusion MVD increases with increase of expression of VEGF and iNOS in gastric cancer. It is indicated that VEGF and iNOS can promote gastric cancer angiogenesis. VEGF and iNOS have a significant positive correlation, which suggests that in human gastric cancer, iNOS plays an important role in the production and action of VEGF.
ObjectiveTo review the characteristics and applications of different implantation in cervical tuberculosis surgery and the research progress of the new implantation. MethodsBy consulting relevant domestic and foreign research literature on cervical tuberculosis, the classification, advantages, disadvantages, and prospects of implantations were analyzed and summarized. ResultsThe incidence of cervical tuberculosis has increased recently and has a high disability rate. Currently, the implantation in the surgical treatment of cervical tuberculosis are mainly divided into bone materials, metal materials, and bioactive materials; the above materials have their own advantages and disadvantages, for example, the amount of autologous bone is limited, the complications of allogeneic bone are common, and the bone fusion effect of metal materials is poor. With the development of science and technology, the implantation are also more diverse. ConclusionThe choice of the implantation affects the bone fusion directly, furthermore, it affects the effectiveness of cervical tuberculosis, the development of new implantation provides a variety of options for the treatment of cervical tuberculosis.
ObjectiveTo evaluate the diagnostic value of various severity assessment scoring systems for sepsis after cardiac surgery and the predictive value for long-term prognosis.MethodsThe clinical data of patients who underwent cardiac sugeries including coronary artery bypass grafting (CABG) and (or) valve reconstruction/valve replacement were extracted from Medical Information Mark for Intensive Care-Ⅲ (MIMIC-Ⅲ). A total of 6 638 patients were enrolled in this study, including 4 558 males and 2 080 females, with an average age of 67.0±12.2 years. Discriminatory power was determined by comparing the area under the receiver operating characteristic (ROC) curve (AUC) for each scoring system individually using the method of DeLong. An X-tile analysis was used to determine the optimal cut-off point for each scoring system, and the patients were grouped by the cut-off point, and Kaplan-Meier curves and log-rank test were applied to analyze their long-term survival.ResultsCompared with the sequential organ failure assessment (SOFA) score, acute physiology score-Ⅲ (APS-Ⅲ, P<0.001), the simplified acute physiology score-Ⅱ (SAPS-Ⅱ, P<0.001) and logistic organ dysfunction score (LODS, P<0.001) were more accurate in distinguishing sepsis. Compared with the non-septic group, the 10-year overall survival rate of the septic group was lower (P<0.001). Except for the systemic inflammation response score (SIRS) system, the 10-year overall survival rates of patients in the high risk layers of SOFA (HR=2.50, 95%CI 2.23-2.80, P<0.001), SAPS (HR=2.93, 95%CI 2.64-3.26, P<0.001), SAPS-Ⅱ (HR=2.77, 95%CI 2.51-3.04, P<0.001), APS-Ⅲ (HR=2.90, 95%CI 2.63-3.20, P<0.001), LODS (HR=2.17, 95%CI 1.97-2.38, P<0.001), modified logistic organ dysfunction score (MLODS, HR=2.04, 95%CI 1.86-2.25, P<0.001) and the Oxford acute severity of illness score (OASIS, HR=2.37, 95%CI 2.16-2.60, P<0.001) systems were lower than those in the low risk layers.ConclusionCompared with SOFA score, APS-Ⅲ score may have higher value in the diagnosis of sepsis in patients who undergo isolated CABG, a valve procedure or a combination of both. Except for SIRS scoring system, SOFA, APS-Ⅲ, SAPS, SAPS-Ⅱ, LODS, MLODS and OASIS scoring systems can be applied to predict the long-term outcome of patients after cardiac surgery.
Objective To explore the effects of intravenous treprostinil in different doses on the hemodynamics and postoperative outcomes after high-risk total cavo-pulmonary connection (TCPC). MethodsFrom 2018 to 2021, among 189 patients who underwent TCPC in the Department of Pediatric Cardiac Surgery of Fuwai Hospital, 26 high-risk patients who received the intravenous treprostinil therapy were retrospectively analyzed. There were 12 males and 14 females, with an age of 4 (3, 6) years and a weight of 17.6±6.2 kg. The patients were divided into two groups: a high-dose group [15 patients, maintaining dose>10 ng/(kg·min)] and a low-dose group [11 patients, maintaining dose≤10 ng/(kg·min)]. The hemodynamics before treprostinil using and during the first 24 hours after reaching the maintaining dose of treprostinil, and postoperative outcomes of the two groups were investigated. ResultsThe incidence of heterotaxia was higher in the high-dose group (66.7% vs. 18.2%, P=0.021). During the observation period, the mean pulmonary artery pressure decreased from 11.9±3.6 mm Hg to 11.0±3.3 mm Hg in the low-dose group (P=0.013), and from 12.9±4.7 mm Hg to 10.2±3.4 mm Hg in the high-dose group (P=0.001). The decreasing effect in the high-dose group was better than that in the low-dose group (P=0.010). There was no statistical difference in the postoperative outcomes between the two groups (P>0.05). In terms of side effects, patients needed temporarily increased dosage of vasoactive drugs to maintain stable blood pressure during 6-12 h after treprostinil therapy in the high-dose group. ConclusionIn patients after high-risk TCPC, intravenous high-dose treprostinil has a better therapeutic effect on reducing pulmonary artery pressure. However, it should be noted that increased dosage of vasoactive agents may be required to maintain blood pressure stability in patients with high-dose treprostinil.
Abstract: Objective To investigate the safety and feasibility of fast track (FT) treatment in young children with atrioventricular septal defect (CAVSD) and pulmonary artery hypertension (PAH) following surgical repair. Methods A total of 51 young children patients including 24 boys and 27 girls with age at 12.5±8.9 months from 4 to 36 months, underwent CAVSD repair in the pediatric surgery department of Fu Wai Hospital from January 2006 to March 2009. Among them, 21 patients were administered FT management. PICU length of stay and the rate of reintubation were analyzed retrospectively and the decrease of pulmonary artery pressure (PAP) after operation was also measured. Results Twentyone patients under FT treatment were extubated within 8 hours after operation. The mean pulmonary artery pressure(MPAP) decreased significantly after surgery (39.59 mm Hg vs.24.50 mm Hg,t=5514,Plt;0.05). PICU length of stay was 2.05±0.87 d (18 h-3 d). One patient was reintubated due to lung infection, which had nothing to do with the FT treatment. During the followup which lasted for 3 to 6 months, 21 patients had good heart function with no reoperation or death. Conclusion FT treatment is safe and feasible to some CAVSD patients associated with PAH, and shorter PICU length of stay can be achieved. The validation of FT model for the CAVSD patients with severe PAH needs research with large sample.
Objective To introduce the current status of clinical research on endoscopic cholecystolithotomy with reservation of gallbladder. Methods Literatures related to the basis, advantage, indication, contraindication, operative method and current controversy were reviewed and summarized. Results The objective evidences were afforded by postoperative complications of cholecystectomy for endoscopic cholecystolithotomy with reservation of gallbladder. The progress of endoscopic technique made it possible for reservation of gallbladder. The controversy in endoscopic cholecystolithotomy with reservation of gallbladder was focused on the choice of indications and operative procedure. Incorrect patient selection and undue pursuit of cholecystolithotomy with reservation of gallbladder would be completely opposite to the treatment of gallstone. Conclusion It is feasible for endoscopic cholecystolithotomy with reservation of gallbladder to remove completely stone and reserve gallbladder function, but further investigation and long-term follow up are required to delineate gallstone recurrence after operation.
