Objective To observe the application effect of ecological nutrition nasogastric enteral nutrition support in postoperative patients with hypertension cerebral hemorrhage. Methods 80 cases of postoperative patients with hypertensive cerebral hemorrhage were randomly divided into ecological nutrition group and control group (n = 40).40 patients of ecological nutrition group were supported by enteral nutrition with probiotics, which started from 24-48 h postoperatively. 40 patients of control group were supported by enteral nutrition without probiotics, which started from 24-48 h postoperatively. Data was collected and analyzed before and after 2 weeks nutrition support. Results Compared with control group, ecological nutrition group' s serum albumin was raised from (33.5 ± 1.3)g/L to (36.3 ± 1.7) g/L, hemoglobin was raised from (124.7±6.8)g/L to (129.4±5.6)g/L, lymphocyte count was raised from (1.61± 0.36)×109/L to (1.97±0.41)×109/L, pulmonary infection were reduced from 8 cases to 1 case, stress ulcer were reduced from 12 cases to 4 cases, GCS (Glasgow Coma Scale) was raised from (9.2 ± 1.3) to (11.4 ± 1.2). All differences were statistically significant (P<0.05). Conclusions Ecological nutrition support could improve nutritional status, enhance immunity, reduce complication, contribute to consciousness resuming and increase efficiency of medical care, which was worthy of popularizing.

Objective To review the experience of surgical repair of aortic origin of pulmonary artery.Methods Fifteen patients underwent surgical correction for aortic origin of pulmonary artery.All of the patients had anomalous origin of right pulmonary artery,and 11 were associated with patent ductus arteriosus,6 with patent foramen ovale,3 with atrial septal defect,2with aortic pulmonic window,1 with ventricular septal defect,1 with interruption of aortic arch,1 with coarctation of aorta and 1 with pulmonary vein stenosis.All patients were associated with severe pulmonary hypertension.All patients were operated on with the implantation of the AORPA to the main pulmonary artery derectly.Results All 15 patients were cured and no died.1 lost follow-up and the other 14 were survivable during a follow-up 3 months to 81 months.one patient recepted pacemaker implantation 2 years after operation because of sinus arrest,no other patients required reoperation.Conclusion Echocardiography combined with spiral ct angiography is a good method for AOPA diagnosis.Good surgical outcome and low reoperation rate of aortic origin of pulmonary artery can be achieved by direct anastomosis.

Objective:To study the application of objective structured clinical examination (OSCE) based on organ system in the practice teaching for clinical interns.Methods:Undergraduate interns majored in clinical medicine in grade 2017 (control group) and 2018 (experimental group) of Jiangjin Central Hospital of Chongqing were selected as the research objects and divided into control group and experimental group. In the control group, the interns received traditional practice teaching, and the interns in the experimental group received traditional bedside teaching combined with OSCE based on organ system. Results of theoretical examination and OSCE test were used to evaluate the teaching effect, and feedbacks were obtained from teachers and students through questionnaire survey and field discussion, so as to compare the differences between the two teaching methods in cultivating clinical ability of medical students.Results:The average scores of theoretical examination of the two groups were similar, the difference was not statistically significant ( P>0.05). In OSCE test, the average scores and total scores of medical history collection station, physical examination station, skill operation station, doctor-patient communication station in the research group were significantly higher than those in the control group ( P<0.05). The average scores of the two groups in the auxiliary examination interpretation station and literature retrieval station were similar, and the differences were not statistically significant ( P>0.05). Conclusion:The OSCE based on organ system is obviously superior to traditional practice teaching in the development of medical students' comprehensive clinical capacity such as medical history collection, physical examination, skill operation and doctor-patient communication.

As a result of right ventricular outflow tract reconstruction, which is the important and basic step of complex cardiac surgery, the blood flow of right ventricular outflow tract is unobstructed, while pulmonary valve regurgitation and right heart dysfunction could be happened. These problems are often ignored in early days, more and more cases of right heart dysfunction need clinical intervention, which is quite difficult and less effective. How to protect effectively the right ventricular function is the focus. At present main methods to protect the right ventricular function include trying to avoid or reduce length of right ventricular incision, reserving or rebuilding the function of the pulmonary valve, using growth potential material for surgery. The protection of the right ventricular function is a systemic project, it involves many aspects, single measures is difficult to provide complete protection, only the comprehensive use of various protection strategy, can help to improve the long-term prognosis.

Objective:This study aimed at reviewing surgical experiences and exploring risk factors for mortality and postoperative complications in patients with infracardiac total anomalous pulmonary venous connection (TAPVC).Methods:This retrospective study included 74 infants who underwent conventional repair (28 cases) and sutureless repair (46 cases) in one hospital from February 2009 to December 2022. Clinical data were reviewed to assess risk factors for mortality and postoperative pulmonary venous obstruction (PVO). Kaplan- Meier curves and cox regressions were applied to analyze the overall survival. Cumulative incidence curve and sub-distribution hazard models were used to evaluate postoperative PVO. Results:There were 4 early deaths and 3 late deaths, and the overall survival rate was 90.5%. A total of 12 patients complicated postoperative PVO. The median follow-up was 39.4 months ( IQR: 13.3 to 73.7 months). The overall survival rate was higher in the sutureless group than the conventional group ( P=0.003). The incidence rate of postoperative PVO in the conventional group was higher than that in the sutureless group ( P= 0.008). Risk factors for recurrent PVO included longer cardiopulmonary bypass time, the increase of direct bilirubin level and international normalized ratio level before surgical repair. Conclusion:Both sutureless and conventional repairs for patients with infracardiac TAPVC can achieve acceptable postoperative outcomes. Sutureless repair has a higher survival rate and a lower incidence of re-stenosis in pulmonary veins and anastomosis.

Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). Methods A retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). Conclusion Compared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.
