Objective To analyze the correlation between ferroptosis and post operative cognitive dysfunction(POCD)in elderly patients with fractures.Methods A total of 120 elderly patients with fracture were divided into the control group and the POCD group according to whether POCD occurred,with 60 cases in each group.Basic data of the two groups were collected.The levels of nerve injury indicators[brain myelin basic protein(MBP),glial fibrillary acidic protein(GFAP)],and fractures markers[glutathione peroxidase 4(GPX4),cyclooxygenase 2(COX2),long-chain acyl-CoA synthase 4(ACSL4)]were detected by enzyme-linked immunosorbent assay at 6 h after surgery.Logistic regression was used to analyze risk factors of POCD in elderly patients with fracture.The correlations between MBP,GFAP and GPX4,COX2 and ACSL4 were analyzed by Pearson correlation analysis.Receiver operating characteristic(ROC)curves were used to analyze predictive values of MBP,GFAP,GPX4,COX2 and ACSL4 levels to POCD.Results The age,proportion of general anesthesia,anesthesia time,intraoperative blood loss and MBP,GFAP,COX2,ACSL4 levels were higher in the POCD group than those in the control group(P＜0.05),while GPX4 was lower than that in the control group(P＜0.05).The levels of MBP and GFAP were negatively correlated with levels of GPX4 in elderly patients with fractures,and positively correlated with levels of COX2 and ACSL4(P＜0.05).Advanced age,general anesthesia,long duration of anesthesia,increased levels of MBP,GFAP,COX2 and ACSL4,and decreased level of GPX4 were independent risk factors for POCD in elderly fracture patients(P＜0.05).The critical values of GPX4,COX2 and ACSL4 for predicting POCD in elderly patients with fractures were GPX4≤23.05 μg/L,COX2≥20.35 μg/L and ACSL4≥237.85 μg/L,and the AUC were 0.869,0.736 and 0.841.The sensitivity was 76.67%,68.33%and 88.33%,and the specificity was 86.67%,78.33%and 75.00%,respectively.The diagnostic efficacy of GFAP,COX2 and ACSL4 was higher than that of MBP and GFAP.Conclusion The incidence of POCD in elderly patients with fracture is associated with ferroptosis,and levels of GPX4,COX2 and ACSL4 have certain predictive value for the incidence of POCD after surgery in elderly patients with fracture.

Objective:To explore the risk factors of paralytic ileus (PI) after simultaneous pancreas-kidney (SPK) transplantation.Methods:From January 2017 to December 2019, clinical data were reviewed retrospectively for 115 cases of SPK transplantation. The risk factors of PI after SPK were analyzed. According to the occurrence of PI, they were divided into two groups of occurrence and non-occurrence. One-way analysis of variance was utilized for analyzing such influencing factors as gender, age, body mass index (BMI), diabetic type, duration of diabetes, mode of dialysis, duration of dialysis, diabetic gastroenterology, history of open surgery, bowel preparation, operative duration, hemorrhagic volume, immunosuppressant and hypoproteinemia. Multivariate Logistic regression analysis was performed for screening the suspected risk factors.Results:Among them, 19 patients (16.5%) had PI. Univariate analysis showed that PI was associated with diabetic gastroenterology, operative duration, history of open surgery, no bowel preparation and hypoproteinemia ( P<0.05). Multivariate Logistic regression analysis revealed that the risk factors of PI after SPK included diabetic gastroenterology, operative duration time, history of open surgery and no bowel preparation ( P<0.05). Conclusions:Diabetic gastroenterology, operative duration, history of open surgery and no bowel preparation are risk factors for PI after SPK. Clinical interventions for the above factors are necessary.

To summarize the clinical experience regarding a patient with early recurrence of atypical hemolytic uremic syndrome (aHUS) after renal transplantation. AHUS is a rare disease with high recurrence rate and poor prognosis. Although the patient was treated with plasma exchange, intravenous gamma globulin, rituximab block B lymphocyte, hormone shock and so on, he still suffered renal transplantation failure. The risk of aHUS recurrence after renal transplantation should be fully evaluated.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective: To investigate the effect factors of liver enzymes elevation by monitoring the liver function changes before and after intraportal islet transplantation. Methods: 16 diabetic patients who received intraportal islet transplantation in our hospital were analyzed. The levels of aspartic aminotransferase (AST), alanine aminotransferase (ALT)and total bilirubin (TBil)were monitored after islet transplantation. Results: Among those 16 diabetic patients who received intraportal islet transplantation, 11 patients showed an increased AST and 8 patients showed an increased ALT, among which a 2.5-fold increase in AST was observed in 4 patients and over 1.5-fold elevation of ALT was observed in 3 patients. The level of TBil were in the normal range before and after transplantation in all patients. Transplanted tissue volume of islet was the main factor for significantly increased AST (P<0.05) in this study. It is also shown that the change in portal pressure is related to the AST elevation after islet transplantation. Conclusions The amount of transplanted islet tissue volume is related to the liver enzymes elevation after intraportal islet transplantation. Therefore, the improvement of the purity of islet to reduce the amount of transplanted tissue could be benefit to prevent the liver injury after islet transplantation. Meanwhile, the purified islets should be injected as slowly as possible to maintain a stable portal pressure.
