Objective:To summarize acute type A aortic dissection(ATAAD) is relatively uncommon in dialysis patients, and repair outcomes are not fully understood.Methods:Between January 2014 and March 2020, 20 patients with ATAAD required dialysis for preoperative end-stage renal disease(ESRD) were treated by our group. There were 11 male and 9 female patients at mean age of(47.8±11.3) years. The mean duration of dialysis therapy in the total 20 patients before the onset of ATAAD was(4.5±3.9 )years, with 90%(18 cases) of these patients undergoing hemodialysis(rather than peritoneal dialysis). 17 patients were treated emergency surgically, surgical operation were performed under deep hypothermic circulatory arrest and perfused the cerebral selective cerebral perfusion, 5 cases with ascending aorta + arch fenestrated stent, 5 cases with ascending aorta+ hemi-arch replacement(2 cases with stent elephant trunk), 4 cases with ascending aorta+ arch replacement+ stent elephant trunk(1 case with coronary artery bypass grafting for left anterior descending coronary artery), 2 cases with aortic valvuloplasty + ascending aorta+ hemi-arch replacement, 1 case with Bentall+ arch fenestrated stent.Results:2 patients were died from aortic ruptured before operation, 1 patient treated medically was alive three months after admission. Cross-clamp, cardiopulmonary bypass, and circulatory arrest times of all the surgical patients were(233.8±84.4) min, (155.5±63.6)min and(28.2±10.8)min, respectively. The following complications occurred postoperative: 3 cases died in the hospital, 1 case of tracheotomy, 2 cases of cerebral infarction, 1 case of cerebral hemorrhage, 1 case of transient paraplegia, and 1 case of surgical site infection. After a mean follow-up of(11.6±14.5) months(rang, 3-61 months). the overall survival rate at 1 year and 5 years was 53% and 27% respectively.Conclusion:Dialysis patients with ATAAD should be operated on urgently and medical treatment carries high risks of aortic rupture, although in-hospital mortality is acceptable, long-term mortality is poor.

Long non-coding RNAs (lncRNAs) are a class of non-coding transcripts which are greater than 200 nucleotides in length and have a variety of biological functions. Studies have found that lncRNAs play an important role in the development of gastrointestinal cancers and can affect tumor cell growth, angiogenesis, metastasis and drug resistance. This paper has reviewed lncRNAs associated with gastrointestinal cancers and explored their roles in the occurrence, diagnosis and treatment of gastrointestinal cancers.

Objective: To analyze the treatment results of cardiac rupture in patients with acute myocardial infarction (AMI) . Method: Clinical data of 6 with cardiac rupture after AMI, who were hospitalized in our hospital from June 2015 to June 2017, were retrospectively analyzed,and the clinical manifestations, methods of treatment and outcomes were investigated. Results: Cardiac function classification was Killip class Ⅱin all patients. There were 3 massive anterior wall myocardial infarction, 2 anterior wall myocardial infarction,and 1 inferior myocardial infarction. There were 4 patients with ventricular septal defect, 1 patient with rupture of papillary muscle,and 1 patient with left ventricular free wall rupture.All patients received continuous infusion of vasoactive medicines and treated with intra-aortic balloon pump(IABP), 2 patients (1 patient accepted operative treatment,and 1 patient received conservative treatment) were treated with extracorporeal membrane oxygenation (ECMO), mechanical ventilation,and continuous renal replacement therapy(CRRT).Three patients received surgical repair,1 case was supported by IABP, 1 case supported by ECMO,CRRT,and IABP,and 1 case did not use IABP or ECMO post operation. All 3 surgically treated patients recovered successfully and were discharged from hospital.Meanwhile, in the other 3 patients treated conservatively, 2 patients died in the hospital and 1 patient was discharged according to own will. Conclusion On the basis of vasoactive medicines and IABP, surgery repair is a feasible option for cardiac rupture patients secondary to AMI,and ECMO may improve the perioperative state in these patients.

Objective:To evaluate the clinical effect of the pulmonary rehabilitation system based on the concept of prehabilitation for patients after cardiac surgery to wean tube and avoid related complications.Methods:From January 2018 to December 2019 in a single-center(third-class hospital in cardiac surgery intensive care unit), all adult patients hospitalized for 7 days before open-heart surgery were included. They were randomly divided into pulmonary rehabilitation group(198 cases) and control group(234 cases). To compare and analyze the clinical effects, the main observations were observed including overall outcome indicators(such as early extubation rate, ICU stay, hospitalization costs, advanced oxygen therapy support after extubation) and lung outcome related indicators(such as the occurrence of pulmonary complications, chest drainage, secondary intubation, tracheotomy, lung infection and chest tube drainage).Results:There was no statistical difference between groups in basic conditions and surgical conditions. The lung rehabilitation group significantly increased the rate of early extubation, reduced the number of advanced oxygen therapy after weaning, shortened the length of ICU stay, saved hospitalization cost, significantly reduced the occurrence of postoperative respiratory complications and improved postoperative respiratory function( P<0.05). Conclusion:During cardiac perioperation, pulmonary rehabilitation significantly can increase the rate of early extubation , shorten the length of mechanical ventilation, reduce the occurrence of secondary tracheal intubation and pulmonary complications. And it can also effectively promote the recovery of lung function and the overall recovery.

Objective To observe the value of cardiac MR(CMR)compressed sensing(CS)sequence and conventional movie(CM)sequence for evaluating biventricular function in patients with congenital heart disease(CHD).Methods A total of 71 patients with CHD,including 31 cases with regular heart rhythm(regular heart rhythm group)and 40 cases with arrhythmia(arrhythmia group)were prospectively collected and scanned with CM and CS sequences.The scanning time of 2 sequences were recorded,and subjective scores of imaging quality of 2 kinds of images were compared.The differences,consistency and correlation between quantitative parameters of biventricular function measured on 2 kinds of images were analyzed.Results The acquisition time of CS was(18.87±1.75)s,of CM was(147.56±5.23)s,which was shortened by 87.21％than CS.The quality of both 2 kinds of images met the diagnostic requirements.The subjective scores of CS images were lower than that of CM in regular heart rhythm group(4[3,5]vs.4[4,5],Z=-2.070,P=0.038),while of CS images were higher than that of CM images in arrhythmia group(4[4,4]vs.3[4,4],Z=-2.673,P=0.008).No significant difference of the left ventricular function parameters was detected obtained based on 2 kinds of images in all 71 cases,nor in regular heart rhythm group as well as in arrhythmia group(all P＞0.05).Meanwhile,the right ventricular(RV)end-diastolic volume index(EDVI)obtained based on CM and CS images were not significantly different(all P＞0.05),but significant differences of ejection fraction(EF),end-systolic volume index(ESVI)and stroke volume index(SVI)were found in all 71 cases,in regular heart rhythm group and in arrhythmia group(all P＜0.05).CMR parameters of biventricular function measured on CM and CS images were all consistent and positively correlated(all P＜0.05).Conclusion CS sequence could be used to accurately assess biventricular function of CHD patients,significantly improve imaging quality and shorten scanning time.

Objective To investigate the risk factors of in-hospital mortality and establish a risk prediction model for patients receiving venoarterial extracorporeal membrane oxygenation(VA-ECMO).Methods We retrospectively collected the data of 302 patients receiving VA-ECMO in ICU of 3 hospitals in Guangdong Province between January,2015 and January,2022 using a convenience sampling method.The patients were divided into a derivation cohort(201 cases)and a validation cohort(101 cases).Univariate and multivariate logistic regression analyses were used to analyze the risk factors for in-hospital death of these patients,based on which a risk prediction model was established in the form of a nomogram.The receiver operator characteristic(ROC)curve,calibration curve and clinical decision curve were used to evaluate the discrimination ability,calibration and clinical validity of this model.Results The in-hospital mortality risk prediction model was established based the risk factors including hypertension(OR=3.694,95%CI:1.582-8.621),continuous renal replacement therapy(OR=9.661,95%CI:4.103-22.745),elevated Na2+ level(OR=1.048,95%CI:1.003-1.095)and increased hemoglobin level(OR=0.987,95%CI:0.977-0.998).In the derivation cohort,the area under the ROC curve(AUC)of this model was 0.829(95%CI:0.770-0.889),greater than those of the 4 single factors(all AUC<0.800),APACHE Ⅱ Score(AUC=0.777,95%CI:0.714-0.840)and the SOFA Score(AUC=0.721,95%CI:0.647-0.796).The results of internal validation showed that the AUC of the model was 0.774(95%CI:0.679-0.869),and the goodness of fit test showed a good fitting of this model(χ2=4.629,P>0.05).Conclusion The risk prediction model for in-hospital mortality of patients on VA-ECMO has good differentiation,calibration and clinical effectiveness and outperforms the commonly used disease severity scoring system,and thus can be used for assessing disease severity and prognostic risk level in critically ill patients.
