Abstract
Hypothermic machine perfusion (HMP) has been demonstrated to be more effective in mitigating ischemia-reperfusion injury (IRI) of donation after circulatory death (DCD) organs than cold storage (CS), yet the underlying mechanism remains obscure. We aimed to propose a novel therapeutic approach to ameliorate IRI in DCD liver transplantation. Twelve clinical liver samples were randomly assigned to HMP or CS treatment and subsequent transcriptomics analysis was performed. By combining in vivo HMP models, we discovered that HMP attenuated inflammation, oxidative stress, and apoptosis in DCD liver through a SEPRINA3-mediated PI3Kδ/AKT signaling cascade. Moreover, in the hypoxia/reoxygenation (H/R) model of BRL-3A, overexpression of SERPINA3 mitigated H/R-induced apoptosis, while SERPINA3 knockdown exacerbated cell injury. Idelalisib (IDE) treatment also reversed the protective effect of SERPINA3 overexpression. Overall, our research provided new insights into therapeutic strategies and identified potential novel molecular targets for therapeutic intervention against DCD liver.

Effect of Perioperative Dexmedetomidine on Delayed Graft Function Following a Donation-After-Cardiac-Death Kidney Transplant: A Randomized Clinical Trial. JAMA Netw Open 2022; 5:e2215217. [PMID: 35657627 PMCID: PMC9166619 DOI: 10.1001/jamanetworkopen.2022.15217] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/04/2023] Open
Abstract
IMPORTANCE Delayed graft function (DGF) is a risk factor for acute rejection and graft failure after kidney transplant. Previous studies have suggested that dexmedetomidine may be renoprotective, but whether the use of dexmedetomidine would improve kidney allograft function is unknown. OBJECTIVE To investigate the effects of perioperative dexmedetomidine on DGF following a donation-after-cardiac-death (DCD) kidney transplant. DESIGN, SETTING, AND PARTICIPANTS This single-center, double-blind, placebo-controlled randomized clinical trial was conducted at The First Affiliated Hospital of Soochow University in Suzhou, China. Adults (18 years or older) who were scheduled for DCD kidney transplant were enrolled between September 1, 2019, and January 28, 2021, and then randomized to receive either dexmedetomidine or normal saline (placebo). One-year postoperative outcomes were recorded. All analyses were based on the modified intention-to-treat population. INTERVENTIONS Patients who were randomized to the dexmedetomidine group received a 24-hour perioperative dexmedetomidine intravenous infusion (0.4 μg/kg/h intraoperatively and 0.1 μg/kg/h postoperatively). Patients who were randomized to the normal saline group received an intravenous infusion of the placebo with the same dose regimen as the dexmedetomidine. MAIN OUTCOMES AND MEASURES The primary outcome was the incidence of DGF, defined as the need for dialysis in the first posttransplant week. The prespecified secondary outcomes were in-hospital repeated dialysis in the first posttransplant week, in-hospital acute rejection, and serum creatinine, serum cystatin C, estimated glomerular filtration rate, need for dialysis, and patient survival on posttransplant day 30. RESULTS Of the 114 patients enrolled, 111 completed the study (mean [SD] age, 43.4 [10.8] years; 64 male patients [57.7%]), of whom 56 were randomized to the dexmedetomidine group and 55 to the normal saline group. Dexmedetomidine infusion compared with normal saline reduced the incidence of DGF (17.9% vs 34.5%; odds ratio [OR], 0.41; 95% CI, 0.17-0.98; P = .04) and repeated dialysis (12.5% vs 30.9%; OR, 0.32; 95% CI, 0.13-0.88; P = .02, which was not statistically significant after multiple testing corrections), without significant effect on other secondary outcomes. Dexmedetomidine vs normal saline infusion led to a higher median (IQR) creatinine clearance rate on postoperative days 1 (9.9 [4.9-21.2] mL/min vs 7.9 [2.0-10.4] mL/min) and 2 (29.6 [9.7-67.4] mL/min vs 14.6 [3.8-45.1] mL/min) as well as increased median (IQR) urine output on postoperative days 2 (106.5 [66.3-175.6] mL/h vs 82.9 [27.1-141.9] mL/h) and 7 (126.1 [98.0-151.3] mL/h vs 107.0 [82.5-137.5] mL/h) and at hospital discharge discharge (110.4 [92.8-121.9] mL/h vs 97.1 [77.5-113.8] mL/h). Three patients (5.5%) from the normal saline group developed allograft failure by the post hoc 1-year follow-up visit. CONCLUSIONS AND RELEVANCE This randomized clinical trial found that 24-hour perioperative dexmedetomidine decreased the incidence of DGF after DCD kidney transplant. The findings support the use of dexmedetomidine in kidney transplants. TRIAL REGISTRATION Chinese Clinical Trial Registry Identifier: ChiCTR1900025493.

Delayed graft function is correlated with graft loss in recipients of expanded-criteria rather than standard-criteria donor kidneys: a retrospective, multicenter, observation cohort study. Chin Med J (Engl) 2020; 133:561-570. [PMID: 32053570 PMCID: PMC7065861 DOI: 10.1097/cm9.0000000000000666] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/02/2022] Open
Abstract
Background: Although the use of expanded-criteria donors (ECDs) alleviates the problem of organ shortage, it significantly increases the incidence of delayed graft function (DGF). DGF is a common complication after kidney transplantation; however, the effect of DGF on graft loss is uncertain based on the published literature. Hence, the aim of this study was to determine the relationship between DGF and allograft survival. Methods: We conducted a retrospective, multicenter, observation cohort study. A total of 284 deceased donors and 541 recipients between February 2012 and March 2017 were included. We used logistic regression analysis to verify the association between clinical parameters and DGF, and Cox proportional hazards models were applied to quantify the hazard ratios of DGF for kidney graft loss. Results: Among the 284 deceased donors, 65 (22.8%) donors were ECD. Of the 541 recipients, 107 (19.8%) recipients developed DGF, and this rate was higher with ECD kidneys than with standard-criteria donor (SCD) kidneys (29.2% vs. 17.1%; P = 0.003). The 5-year graft survival rate was not significantly different between SCD kidney recipients with and without DGF (95.8% vs. 95.4%; P = 0.580). However, there was a significant difference between ECD kidney recipients with and without DGF (71.4% vs. 97.6%; P = 0.001), and the adjusted hazard ratio (HR) for graft loss for recipients with DGF was 1.885 (95% confidence interval [CI] = 1.305–7.630; P = 0.024). Results showed that induction therapy with anti-thymocyte globulin was protective against DGF (odds ratio = 0.359; 95% CI = 0.197–0.652; P = 0.001) with all donor kidneys and a protective factor for graft survival (HR = 0.308; 95% CI = 0.130–0.728; P = 0.007) with ECD kidneys. Conclusion: DGF is an independent risk factor for graft survival in recipients with ECD kidneys, but not SCD kidneys.

Contrast-enhanced ultrasonography to evaluate risk factors for short-term and long-term outcomes after liver transplantation: A pilot prospective study. Eur J Radiol 2020; 135:109475. [PMID: 33373895 DOI: 10.1016/j.ejrad.2020.109475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Revised: 11/16/2020] [Accepted: 12/07/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE To evaluate whether Doppler ultrasonography (DUS) and contrast-enhanced ultrasonography (CEUS) can identify liver donation after brain death (DBD) and cardiac death (DCD) with the risk of developing short-term primary graft dysfunction (PGD) or arterial and biliary complications within 1 year. MATERIALS AND METHODS Consecutive DBD and DCD donors who underwent DUS/CEUS examinations before surgical procurement from February 2016 to June 2018 at our institution were included. The US and CEUS images of each donor liver were analysed, and the parameters were recorded. RESULTS The mean time for US examination was 32 min (range, 20-59 min), and all donors tolerated the examination well. In terms of short-term outcomes, among the 52 eligible donor livers, 20 (38.5 %) of their recipients developed PGD. The multivariable analysis showed that decreased enhancement of donor livers on CEUS (OR = 15.976, 95 % CI: 1.652-154.628, P = 0.017) and high recipient model for end-stage liver disease (MELD) scores (OR = 1.050, 95 % CI: 1.004-1.099, P = 0.034) before liver transplantation (LT) were independent factors of PGD. In contrast, for long-term complications, among the 48 eligible donor livers, 16 (33.3 %) developed arterial or biliary complications within 1 year. The multivariable analysis did not show any independent factors of arterial or biliary complications within 1 year. CONCLUSIONS A decrease in enhancement on CEUS is an independent risk factor for poor short-term outcomes of LT. CEUS may be promising for predicting post-LT outcomes of critically ill donors effectively and safely by evaluating the haemodynamic changes in DBD and DCD donor livers.

Abstract
Investigate the effect of mild hypothermia on serum inflammatory factor HMGB1 of brain-dead donors, and its significance for renal transplantation recipients.In our hospital between January 2018 and January 2019 up to the standard of brain death donor (aged 18 to 65 years old) prospective cohort study, brain death donor were randomly divided into mild hypothermia group and the non-mild hypothermia group. Serum were collected from donor at different periods, and enzyme-linked immunoassay (ELISA) was used to determine the serum HMGB1 concentration to compare the difference between the 2 donor groups. The early recovery of renal function after renal transplantation was followed up, and the incidence of delayed graft function (DGF) and early recovery of renal function were compared between the 2 groups. The correlation between donor HMGB1 and recipient DGF was analyzed.Between 17 donors in the mild hypothermia group and 17 in the non-mild hypothermia group, there were no statistically significant differences in the age, perioperative urine volume and ICU stay between the 2 groups. After mild hypothermia treatment, serum HMGB1 levels of brain death donors were significantly decreased. While in non-mild hypothermia brain death donor group without treatment, serum HMGB1 was significantly increased. There were no statistically significant differences in age and preoperative creatinine between the 2 recipient groups, including 33 patients in the mild hypothermia group and 34 patients in the non-mild hypothermia group. DGF incidence was lower in mild hypothermia group comparing with non-mild hypothermia group with statistical significance. The levels of HMGB1 from donor before procurement is correlated with the occurrence of DGF of the recipient.Mild hypothermia therapy can reduce the levels of serum HMGB1, improve the function of donor organs. The levels of HMGB1 before donor procurement can be used to predict the occurrence of DGF in kidney transplant recipients. Our study shows that HMGB1 can be potentially used as therapeutic target of early intervention for brain death donors. Furthermore, mild hypothermia therapy can be applied in the maintenance of brain death donors for kidney transplant recipient to improve the successful rate of transplantation.

Liver Transplantation from Voluntary Organ Donor System in China: A Comparison between DBD and DCD Liver Transplants. Gastroenterol Res Pract 2019; 2019:5736702. [PMID: 31191649 PMCID: PMC6525890 DOI: 10.1155/2019/5736702] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2018] [Accepted: 04/11/2019] [Indexed: 02/07/2023] Open
Abstract
Background In China, the cases of liver transplantation (LT) from donation after citizens' death have rose year by year since the citizen-based voluntary organ donor system was initiated in 2010. The objective of our research was to investigate the early postoperative and late long-term outcomes of LT from donation after brain death (DBD) and donation after circulatory death (DCD) according to the current organ donation system in China. Methods Sixty-two consecutive cases of LT from donation after citizens' death performed in our hospital between February 2012 and June 2017 were examined retrospectively for short- and long-term outcomes. These included 35 DCD LT and 27 DBD LT. Result Subsequent median follow-up time of 19 months and 1- and 3-year graft survival rates were comparative between the DBD group and the DCD group (81.5% and 66.7% versus 67.1% and 59.7%; P = 0.550), as were patient survival rates (85.2% and 68.7% versus 72.2% and 63.9%; P = 0.358). The duration of ICU stay of recipients was significantly shorter in the DBD group, in comparison with that of the DCD group (1 versus 3 days, P = 0.001). Severe complication incidence (≥grade III) after transplantation was identical among the DBD and DCD groups (48.1% versus 60%, P = 0.352). There was no significant difference in postoperative mortality between the DBD and DCD groups (3 of 27 cases versus 5 of 35 cases). Twenty-one grafts (33.8%) were lost and 18 recipients (29.0%) were dead till the time of follow-up. Malignancy recurrence was the most prevalent reason for patient death (38.8%). There was no significant difference in incidence of biliary stenosis between the DBD and DCD groups (5 of 27 cases versus 6 of 35 cases, P = 0.846). Conclusion Although the sample size was small to some extent, this single-center study first reported that LT from DCD donors showed similar short- and long-term outcomes with DBD donors and justified the widespread implementation of voluntary citizen-based deceased organ donation in China. However, the results should be verified with a multicenter larger study.

Outcome of the use of paediatric donor livers in adult recipients: A single Chinese centre experience. Clin Res Hepatol Gastroenterol 2019; 43:148-154. [PMID: 30318357 DOI: 10.1016/j.clinre.2018.08.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 08/22/2018] [Accepted: 08/30/2018] [Indexed: 02/04/2023]
Abstract
BACKGROUND Paediatric liver allografts sometimes are allocated to adult recipients when there are no suitable paediatric recipients on the waiting list. However, debate exits regarding the reported outcomes of liver transplants using such small grafts. METHODS Records from adult patients undergoing liver transplantation between February 2010 and January 2016 who received whole grafts from paediatric (≤ 13 years) donors or ideal deceased adult (18-35 years) donors were reviewed. Patient and graft survival, post-transplant liver function, and complications between the two groups were compared. RESULTS The baseline characteristics were comparable, except that the paediatric donor allografts had smaller size. The 3-month, 1-year, and 3-year rates of patient survival were 91.3%, 85.2%, and 85.2% in the paediatric donor group and 93.4%, 88.9%, and 85.0% in the adult donor group (P = 0.947), respectively. One patient receiving a paediatric allograft developed small-for-size liver syndrome post-transplantation. There was no difference in primary non-function, early allograft dysfunction, biliary complications, vascular complications, or infection between the two groups. CONCLUSION Our study indicates that using paediatric donor livers in well-selected adult recipients is a safe procedure, considering there was no suitable paediatric recipient. However, the risk of portal hyperperfusion should be considered in clinical cases such as size-mismatched transplants.

Donation after brain death followed by circulatory death, a novel donation pattern, confers comparable renal allograft outcomes with donation after brain death. BMC Nephrol 2018; 19:164. [PMID: 29973175 PMCID: PMC6032600 DOI: 10.1186/s12882-018-0972-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2018] [Accepted: 06/26/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Organ donation after brain death (DBD) is the standard strategy for organ transplantation; however, the concept of brain death is not universally accepted due to cultural beliefs and barriers amongst billions of people worldwide. Hence, a novel donation pattern has been established in China which outlines the concept of donation after brain death followed by circulatory death (DBCD). Differently from any current donation classification, this new concept is formulated based on combination of recognizing brain death and circulatory death. Should approval be gained for this definition and approach, DBCD will pave a novel donation option for billions of people who cannot accept DBD due to their cultural beliefs. METHODS A multi-center, cohort study was conducted from February 2012 to December 2015. 523 kidney transplant recipients from four kidney transplant institutions were enrolled into the study, of which, 383 received kidneys from DBCD, and 140 from DBD. Graft and recipient survivals following transplantation were retrospectively analyzed. Postoperative complications including delayed graft function,, and acute rejection, were also analyzed for both groups. RESULTS DBCD could achieve comparable graft and recipient survivals in comparison with DBD (Log-rank P = 0.32 and 0.86,respectively). One-year graft and recipient survivals were equal between DBCD and DBD groups (97.4% versus 97.9%, P = 0.10;98.4% versus 98.6%, P = 1.0, respectively). Furthermore, DBCD did not increase incidences of postoperative complications compared with DBD, including delayed graft function (19.3% versus 22.1%, P = 0.46) and acute rejection (9.1% versus 8.6%, P = 1.0). Additionally, antithymocyte globulin as induction therapy and shorter warm ischemia time decreased incidence of delayed graft function in DBCD group (16.8% on antithymocyte globulin versus 27.2% on basiliximab, P = 0.03; 16.7% on ≤18 min versus 26.7% on > 18 min group, P = 0.03). CONCLUSIONS Kidney donation through DBCD achieves equally successful outcomes as DBD, and could provide a feasible path to graft availability for billions of people who face barriers to organ donation from DBD.

Abstract
OBJECTIVES This study aimed to investigate the outcomes of adult liver transplant procedures using grafts from pediatric donors after circulatory death. MATERIALS AND METHODS We retrospectively analyzed the data of 19 pediatric-to-adult liver transplant procedures from July 2013 to May 2016 in our hospital. Nineteen adult liver transplant procedures were performed using livers from pediatric donors after circulatory death. RESULTS We performed 18 orthotopic and 1 piggyback liver transplant procedure. The median graft-to-recipient weight ratio was 1.26% (range, 0.86% to 2.46%). The median warm and cold ischemia times were 11 minutes (range, 8-20 min) and 638 minutes (range, 200-843 min), respectively. Complications after the operation included postoperative pulmonary infection (8 patients), fungal infection (1 patient), cytomegalovirus infection (1 patient), hepatic artery thrombosis and biliary stricture (1 patient), portal vein stenosis (1 patient), and graft failure (2 patients). For patients with graft failure, 1 patient received retransplant and 1 died. The patients were followed for 22.44 months (range, 9.63-44.07 mo) after transplant and showed normal liver function and good health. The 3-year survival rates of grafts and patients were 89.47% and 94.74%, respectively. CONCLUSIONS Appropriate evaluation of donors and recipients and accurate intraoperative and postoperative treatment can ensure successful application of livers from pediatric donors after circulatory death in adult recipients.

Outcome Improvement for Hypothermic Machine Perfusion Versus Cold Storage for Kidneys From Cardiac Death Donors. Artif Organs 2018; 41:647-653. [PMID: 28703374 DOI: 10.1111/aor.12828] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2016] [Revised: 07/09/2016] [Accepted: 07/18/2016] [Indexed: 11/30/2022]
Abstract
Organ shortage has led to an increased use of kidneys from cardiac death donors (DCDs), but controversies about the methods of organ preservation still exist. This study aims to compare the effect of machine perfusion (MP) and cold storage (CS) in protecting kidneys harvested from DCDs. 141 kidney pairs from DCDs between July 2010 and July 2015 were included in this randomized controlled study. One kidney from each donor was randomly assigned to MP and the contralateral kidney was assigned to CS. Delayed graft function (DGF) rate, resistance index of renal arteries, early renal function, and survival rates were used to estimate the effect of preservation. The results showed that MP decreased the rate of DGF from 33.3 to 22.0% (P = 0.033). Ultrasound of the kidneys within 48 h after transplantation showed that the resistance index of renal main artery (0.673 ± 0.063 vs. 0.793 ± 0.124, P < 0.001), sub segmental artery (0.66 ± 0.062 vs. 0.764 ± 0.077, P < 0.001) and interlobular artery (0.648 ± 0.056 vs. 0.745 ± 0.111, P = 0.023) were all significantly lower in the MP group than those in the CS group. Furthermore, compared to the CS group, in the first 7 days following transplantation, the median urine volume was significantly higher (4080 mL vs. 3000 mL, P = 0.047) in kidneys sustained using MP and the median serum creatinine was remarkably lower (180 µmol/L vs. 390 µmol/L, P = 0.024). More importantly, MP group had higher 1- and 3-year graft survival rates (98% vs. 93%, P = 0.026; 93% vs. 82%, P = 0.036, respectively). Hypothermic MP improved the outcomes of DCD kidney transplantation.

Abstract
BACKGROUND The outcome of pediatric deceased donor liver transplantation (LT) has not been well studied, especially pediatric deceased donor livers used in adult transplantation. This study aimed to evaluate the efficacy of LT using pediatric deceased donor livers and compare the outcomes between pediatric-to-pediatric LT and pediatric-to-adult LT. METHODS A retrospective review of LT using pediatric deceased donor livers from June 2013 to August 2016 was performed. The patients were divided into the pediatric-to-pediatric LT group and pediatric-to-adult LT group based on the ages of the recipients. The survival and incidence of early vascular complications (VCs) were observed between the two groups. We also analyzed the risk factors of early VCs in pediatric LT and the effect of donor hypernatremia on the prognosis of recipients. RESULTS There were 102 cases of LT using pediatric deceased donor livers in our hospital from June 2013 to August 2016, 83 pediatric-to-pediatric LT (recipients' age ≤13 years) and 19 pediatric-to-adult LT (recipients' age ≥19 years). The ratio of early VC was similar in the two groups (19.3% vs. 10.6%, P = 0.514). Low body weight of recipient was an independent risk factor of early VC in pediatric LT (odds ratio: 0.856, 95% confidence interval: 0.752-0.975, P = 0.019). The 1-year cumulative survival rates of grafts and patients were 89.16% and 91.57% in pediatric-to-pediatric LT and 89.47% and 94.74% in pediatric-to-adult LT, respectively (all P > 0.05). In all cases, patients using donors with hypernatremia (serum sodium levels ≥150 mmol/L) had worse graft survival (χ2=4.330, P = 0.037). CONCLUSIONS Pediatric-to-pediatric LT group has similar graft and patient survival rates with those of pediatric-to-adult LT group. Low body weight of recipients is an independent risk factor of early VC in pediatric LT. Patients using donors with hypernatremia have worse graft survival.

Abstract
BACKGROUND Kidneys from deceased donors are being used to meet the growing need for grafts. However, delayed graft function (DGF) and acute rejection incidences are high, leading to adverse effects on graft outcomes. Optimal induction intervention should include both renal structure injury repair and immune response suppression. Mesenchymal stem cells (MSCs) with potent anti-inflammatory, regenerative, and immune-modulatory properties are considered a candidate to prevent DGF and acute rejection in renal transplantation. Thus, this prospective multicenter paired study aimed to assess the clinical value of allogeneic MSCs as induction therapy to prevent both DGF and acute rejection in deceased donor renal transplantation. METHODS Forty-two renal allograft recipients were recruited and divided into trial and control groups. The trial group (21 cases) received 2 × 106/kg human umbilical-cord-derived MSCs (UC-MSCs) via the peripheral vein before renal transplantation, and 5 × 106 cells via the renal artery during the surgical procedure. All recipients received standard induction therapy. Incidences of DGF and biopsy-proven acute rejection were recorded postoperatively and severe postoperative complications were assessed. Graft and recipient survivals were also evaluated. RESULTS Treatment with UC-MSCs achieved comparable graft and recipient survivals with non-MSC treatment (P = 0.97 and 0.15, respectively). No increase in postoperative complications, including DGF and acute rejection, were observed (incidence of DGF: 9.5% in the MSC group versus 33.3% in the non-MSC group, P = 0.13; Incidence of acute rejection: 14.3% versus 4.8%, P = 0.61). Equal postoperative estimated glomerular filtration rates were found between the two groups (P = 0.88). All patients tolerated the MSCs infusion without adverse clinical effects. Additionally, a multiprobe fluorescence in situ hybridization assay revealed that UC-MSCs administered via the renal artery were absent from the recipient's biopsy sample. CONCLUSIONS Umbilical-cord-derived MSCs can be used as clinically feasible and safe induction therapy. Adequate timing and frequency of UC-MSCs administration may have a significant effect on graft and recipient outcomes. Trial registration NCT02490020 . Registered on June 29 2015.

Abstract
PURPOSE In spite of the increasing success of liver transplantation, there remains inevitable risk of postoperative complications, re-operations, and even death. Risk factors that correlate with post-transplant death have not been fully identified. MATERIALS AND METHODS We performed a retrospective analysis of 65 adults that received donation after circulatory death liver transplantation. Binary logistic regression and Cox's proportional hazards regression were employed to identify risk factors that associate with postoperative death and the length of survival period. RESULTS Twenty-two recipients (33.8%) deceased during 392.3 ± 45.6 days. The higher preoperative Child-Pugh score (p = .007), prolonged postoperative ICU stay (p = .02), and more postoperative complications (p = .0005) were observed in deceased patients. Advanced pathological staging (p = .02) with more common nerve invasion (p = .03), lymph node invasion (p = .02), and para-tumor satellite lesion (p = .01) were found in deceased group. The higher pre-transplant Child-Pugh score was a risk factor for post-transplant death (OR = 4.38, p = .011), and was correlated with reduced post-transplant survival period (OR = 0.35, p = .009). Nerve invasion was also a risk factor for post-transplant death (OR = 13.85, p = .014), although it failed to affect survival period. CONCLUSIONS Our study emphasizes the impact of recipient's pre-transplant liver function as well as pre-transplant nerve invasion by recipient's liver cancer cells on postoperative outcome and survival period in patients receiving liver transplantation.

Abstract
OBJECTIVE Organ donation with scheduled cardiac arrest after brain death (s-DBCD) is a special category in China. This study was to evaluate the procedure of pediatric s-DBCD, graft quality, and clinical outcomes of single kidney transplantation. METHODS We retrospectively analyzed the data of 8 Chinese pediatric donors. RESULTS The death causes of the donors (age 4-12 years) were cerebral hypoxia after cardiopulmonary resuscitation (n = 1), intracranial vascular malformation (n = 1), severe traumatic brain injury (n = 3), and brain malignancy (n = 3). The functional warm ischemia time of the grafts was 18 (13-26) minutes. Sixteen kidneys were recovered using liver-kidney en bloc procurement after in situ perfusion. All kidneys had a length >7 cm and were transplanted to 3 adolescent and 13 adult recipients. Two cases of delayed graft function occurred. The patients had a median serum creatinine level of 97 (55-123) μmol/L by the last visit. The median estimated glomerular filtration rate level was 85.4 (58-136) mL/min. Five episodes of biopsy-proven acute rejection occurred in 4 patients, which were reversed by methylprednisolone pulse therapy. Renal arterial stenosis was observed in 1 patient, which was cured by interventional balloon dilatation and stent implantation. CONCLUSION Pediatric s-DBCD is feasible with acceptable graft quality. Single kidney transplantation with pediatric graft size >7 cm has good clinical outcomes.

Abstract
The aim of this study was to determine the role of ALDH2 in the injury of liver from brain-dead donors. Using brain-dead rabbit model and hypoxia model, levels of ALDH2 and apoptosis in tissues and cell lines were determined by Western blot, flow cytometry (FCM), and transferase (TdT)-mediated biotin-16-dUTP nick-end labeling (TUNEL) assays. After the expression of ALDH2 during hypoxia had been inhibited or activated, the accumulations of 4-hydroxynonenal (4-HNE) and molecules involved in mitogen-activated protein kinase (MAPK) signaling pathway were analyzed using ELISA kit and Western blot. The low expression of phosphorylated ALDH2 in liver was time-dependent in the brain-dead rabbit model. Immunohistochemistry showed ALDH2 was primarily located in endothelial, and the rates of cell apoptosis in the donation after brain-death (DBD) rabbit groups significantly increased with time. Following the treatment of inhibitor of ALDH2, daidzein, in combination with hypoxia for 8 h, the apoptosis rate and the levels of 4-HNE, P-JNK, and cleaved caspase-3 significantly increased in contrast to that in hypoxic HUVECs; however, they all decreased after treatment with Alda-1 and hypoxia compared with that in hypoxic HUVECs (P < 0.05). Instead, the levels of P-P38, P-ERK, P-JNK, and cleaved caspase-3 decreased and the ratio of bcl-2/bax increased with ad-ALDH2 (10(6) pfu/ml) in combination with hypoxia for 8 h, which significantly alleviated in contrast to that in hypoxic HUVECs. We found low expression of ALDH2 and high rates of apoptosis in the livers of brain-dead donor rabbits. Furthermore, decreased ALDH2 led to apoptosis in HUVECs through MAPK pathway.
