Objective To explore the causes, diagnosis and treatment of pulmonary mucor infection after kidney transplantation from citizens' death organ donation. Methods A retrospective analysis was performed for the causes, diagnosis and treatment of 4 cases of typical pulmonary mucor infection since the implementation of organ donation and kidney transplantation after death at our hospital from January 2015 to June 2019. Results Among 4 patients with severe clinical symptoms, 3 survived after timely symptomatic treatments and 1 patient died due to mucor invasion of pulmonary blood vessels and hemothorax. Conclusions Pulmonary mucor infection is often rapid, aggressive and even fatal after kidney transplantation from citizens' death organ donation. For saving the life of transplant recipients, it is vital to save to withdraw or lower the dose of immunosuppressive agents timely and use antibacterial agents against mucor alone or jointly according to clinical condition.

Objective To explore the risk factors, diagnosis and treatment of early portal vein complications after liver transplantation. Methods From January 2016 to December 2018, clinical data of 616 adult patients undergoing liver transplantation were retrospectively analyzed. Nine cases (1.5%) had early portal vein complications. By comparing the general status of recipients and donors and the intraoperative findings, the risk factors of early portal vein complications were analyzed. Results No statistically significant differences existed in recipient age, gender, donor/recipient blood type, donor liver cold ischemia time, transplant operative duration, intraoperative non-hepatic period, intraoperative blood loss or intraoperative red blood cell transfusion (P>0.05). However, preoperative recipients had portal vein thrombosis, splenectomy, retransplantation and portal vein anastomosis. Statistical differences existed and all were risk factors for early portal vein complications (P<0.05). Binary logistic regression showed that preoperative patients had portal vein thrombosis [OR=16.922, 95% CI(1.859-154.059), P=0.012] and retransplantation [OR=64.871, 95% CI(8.293-507.435), P<0.001] was an independent risk factor for early portal vein complications. Nine cases of early portal vein complications were confirmed by ultrasound and/or computed tomography (CT) angiography. Three patients with portal vein thrombosis type 1 received oral medication while another three with portal vein thrombosis type 2 underwent abdominal portal vein incision, thrombectomy and large omental portal vein pump implantation. During a follow-up period of (22±14.8) months, portal vein blood flow remained patent. One patient with portal vein stenosis underwent portal vein balloon dilation and stent implantation. During a follow-up period of 17 months, portal vein blood flow remained patent. Two patients with abnormal portal vein blood flow underwent liver re-transplantation and died postoperatively. Conclusions Preoperative portal vein thrombosis and splenectomy, re-transplantation of liver and end-to-end anastomosis of non-donor recipient portal vein are risk factors for early portal vein complications after liver transplantation. Individualized treatments of portal vein thrombosis may be provided according to the type of thrombus and liver function. And the prognosis is decent. Because of a higher mortality rate, attention should be paid to patients with abnormal portal vein blood flow immediately after re-transplantation.

Objective To explore the incidence, clinical characteristics and prognosis of nervous system(NS) complications after hematopoietic stem cell transplantation (HSCT) in children and further evaluate the occurring risk factors of NS complications and category characteristics. Methods From October 2010 to June 2018, retrospective analysis was performed for 330 HSCT children. Results Twenty-six children developed NS complications after HSCT. Risk factor analysis revealed that the incidence of NS complications were 33.3% in Fanconi anemia, 19.2% in myelodysplastic/myeloproliferative neoplasm (MDS/MPN), 7.3% in acute leukemia, 7.0% in aplastic anemia, 3.1% in genetic immunodeficiency disease, none in other disease (P=0.027). The median age of children with NS complications was 9(4.75-12) versus 6(3-10) (P=0.02) those without NS complications. The incidence of NS complications with and without GVHD>2 degree were 24%(6/25) and 6.6%(20/305)(P=0.002). Different types of NS complications were analyzed, including 53.9% immune-mediated encephalopathy, 26.9% cerebrovascular lesion, one case of transplantation associated thrombotic microangiopathy (TA-TMA), 7.7% drug therapy-related toxic encephacopathy, 3.8% metabolic encephalopathy and 7.7% peripheral neuropathy. The mortality of NS complications was 34.6% and those with immune-mediated encephalopathy had the highest mortality (13/19, 68.4%). However, those with drug therapy-related toxic encephacopathy, metabolic encephalopathy and peripheral neuropathy all survived after HSCT. The overall survival rate was higher in children without NS complications than those with NS complications. Conclusions The incidence of NS complications after HSCT is correlated with primary diseases, age and GVHD >2 degree. Children with drug therapy-related toxic encephacopathy, metabolic encephalopathy and peripheral neuropathy have better prognosis than those with immune-mediated encephalopathy and TA-TMA. Reducing NS complications may improve long-term survival of children after HSCT.

Objective To explore the clinical efficacy and risk factors of mortality for liver transplantation in patients with acute liver failure. Methods From January 2012 to December 2017, retrospective analysis was performed for 31 patients with acute liver failure undergoing orthotopic liver transplantation. Clinical data and follow-up data were recorded. Univariate survival analysis was performed by Kaplan-Meier and Log-rank tests while multivariate survival analysis conducted by proportional hazards model. Results Age ≥55 years, preoperative hepatorenal syndrome, perioperative infection and preoperative non-molecular adsorbent recirculating system (MARS) support were influencing factors of postoperative survival rate by univariate survival analysis (P<0.05). Preoperative infection was an independent risk factor for survival after liver transplantation by multivariate COX regression analysis (P<0.01). Conclusions Liver transplantation is an effective treatment for acute liver failure. And preoperative infection is an independent risk factor for survival after liver transplantation.

Objective To examine the protective effect of preoperatively oral hydrogen-rich water on attenuating renal ischemia-reperfusion (I/R) injury of kidney transplantation in rats and explore the related mechanism. Methods Orthotopic kidney transplantation was performed in Sprague-Dawley rats (n=6). Pretreatment of hydrogen-rich and conventional water started at 1 week pre-transplantation. Conventional water was provided for both donors and recipients in control (C) group, hydrogen-rich water for recipients and conventional water for donors in hydrogen-water-treated recipient (HWR) group, hydrogen-rich water for donors and common water for recipients in hydrogen-water-treated donor (HWD) group, hydrogen-rich water for both donors and recipients in hydrogen-water-treated donor and recipient (HWDR) group. Renal function, oxidative stress, inflammatory and apoptotic parameters were monitored at 24h post-reperfusion. The phosphorylation of p38 in kidney graft was assayed by Western blot. Results As compared with C group, renal function of recipients became ameliorated in HWR/HWD/HWDR group. Meanwhile, oxidative stress and inflammatory response were mitigated and lessened pathological injury and apoptosis of renal tubular epithelial cells coincided with suppressing apoptosis-related protein's generation and phosphorylation of p38 (P<0.05). Compared with HWR group, the above differences were more significant in HWD and HWDR groups (P<0.05). Conclusions Preoperative intake of hydrogen water attenuates renal I/R injury after kidney transplantation. And suppressing the activation of p38 MAPK may be a potential mechanism.

Objective Hepatic artery thrombosis(HAT) is one of serious complications after liver transplantation. This study was intended to explore the effect of HAT on survival rate of patients/grafts and biliary complications early after liver transplantation with controlled donation after circulatory death (CDCD) donors in children. Methods The clinical data of 236 children with CDCD donor liver transplantation (donor age <14 years) were retrospectively analyzed. Among them, 37 patients developed HAT early postoperatively. The survival rate of patients/grafts and the occurrence of biliary complications were compared between two groups. Results The median follow-up period was 23 months. For HAT (n=37) and non-HAT (n=199) group, the median follow-up period was 27 and 22 months respectively. The 1-year and 3-year survival rates of grafts were 88.2%, 88.2% and 93.2%, 92.4% respectively. And no inter-group statistical difference existed (P=0.373). The 1-year and 3-year graft survival rates were 73.9%, 73.9% and 91.8%, 90.5% respectively. And inter-group statistical difference existed (P<0.01). The incidence of biliary leakage and biliary stricture were 13.5% and 2% and 29.7% and 5.5% respectively. Inter-group statistical differences existed. In HAT group, there were liver failure (n=7, 18.9%) and death (n=3, 8.1%) after transplantation. Conclusions HAT is one of the serious complications after liver transplantation. An early onset of HAT increases the incidence of biliary complications and graft loss in children after CDCD donor liver transplantation. For patients with graft failure, liver re-transplantation may be performed at the right time.

Objective To explore the expression and significance of v-domain Ig suppressor of T cell activation (VISTA) in the clinical samples of hepatocellular carcinoma (HCC). Methods Sixty-nine cases of HCC were recruited as research subjects. Tissue microarrays containing tumor and adjacent tissue were prepared. Immunohistochemical staining of VISTA was performed for analyzing the correlation between the expression of VISTA, its clinicopathological factors and the prognosis of HCC. Results The positive rates of VISTA were 8.70%(6/69), 100%(69/69) and 65.22%(45/69) for tumor cells, intratumoral lymphocytes and vascular endothelial cells respectively. The expression of VISTA of intratumoral lymphocytes in adjacent tissues was higher than that in tumor central area (P 0.05). No difference of statistical significance between clinicopathological features and the expression of VISTA in tumor cells (P<0.05). Kaplan-Meier survival curve analysis indicated that the overall survival and recurrence-free survival rates of VISTA low-expression group were markedly higher than those of VISTA high-expression group (P<0.05). Conclusions The expression of VISTA in HCC is predominantly concentrated in intratumoral lymphocytes. It is associated with tumor size. And an elevated expression of VISTA may be a potential marker of poor prognosis in HCC patients. VISTA is expected to be a new therapeutic target for HCC.

Immunohistochemical staining of VISTA was performed for analyzing the correlation between the expression of VISTA, its clinicopathological factors and the prognosis of HCC. \u0000 \u0000 \u0000Results \u0000The positive rates of VISTA were 8.70%(6/69), 100%(69/69) and 65.22%(45/69) for tumor cells, intratumoral lymphocytes and vascular endothelial cells respectively. The expression of VISTA of intratumoral lymphocytes in adjacent tissues was higher than that in tumor central area (P 0.05). No difference of statistical significance between clinicopathological features and the expression of VISTA in tumor cells (P<0.05).

Objective To explore the efficacy and safety of converting from traditional calcineurin inhibitor-based immunosuppressive regimen to sirolimus plus low-dose calcineurin inhibitor after kidney transplantation from expanded criteria donors. Methods For this prospective, open-label, non-randomized controlled clinical trial, 15 recipients of initial transplant from expanded criteria donors received sirolimus plus low-dose calcineurin inhibitor regimen 3 months after transplantation during June 2017 and March 2018. The follow-up period was over 1 year. The allograft survival time, changes in blood creatinine and glomerular filtration rate before and after conversion (0, 1, 3, 6, 12 months), changes in urinary protein before and after conversion, incidence of acute rejection after conversion, BK virus or cytomegalovirus infection and sirolimus-related complications were observed. Results Renal functions of all 15 patients improved after conversion and 1-year allograft survival rate was 100% (15/15). Serum creatinine decreased markedly and glomerular filtration rate increased significantly at 1 month and 3 months after conversion (P<0.05). BK viruria was detected in 5 patients before conversion. After conversion, BK virus turned into negative in 3 patients within 3 months and viral load also decreased in another 2 patients. After conversion, only 2 patients (13.3%) developed de novo proteinuria. Eight patients (53.3%) developed de novo hypertriglyceridemia responding well to medications. None of them experienced acute rejection during follow-ups. Conclusions Sirolimus plus low-dose calcineurin inhibitor is a safe and effective maintenance immunosuppressive regimen for recipients of kidneys from expanded criteria donors, especially for those with abnormal renal function during recovery. But it cannot completely replace the traditional immunosuppressive regimen. Individualized treatment should be chosen properly for recipients.

Objective To explore the clinical efficacies of applying aged marginal donor liver. Methods From January 2015 to June 2018, clinical data were retrospectively analyzed for 199 adult liver transplantation donors and recipients. They were divided into two groups of aged (≥60 years) and appropriate age (<60 years). The prognosis of two groups was compared after a follow-up period of 1 year. And the aged group was further assigned into lower and higher fat infiltration groups according to the degree of fat infiltration in donor liver and compared the prognosis of two groups. Results No significant differences existed in initial, peak value and recovery time of transaminase (AST/ALT), peak value and recovery time of total bilirubin, glutamyl transpeptidase, alkaline phosphatase, international normalized ratio (INR), peak value of lactate, postoperative hospital stay, graft dysfunction, biliary/vascular complications, acute/chronic rejection or graft survival rate between aged and appropriate age groups post-transplantation. The aged group was further divided into lower and higher fat infiltration groups according to the fat infiltration rate (<20%, ≥20%). And significant inter-group differences existed in peak value and recovery time of AST/ALT, peak value of total bilirubin, glutamyl transpeptidase, lactate, postoperative hospital stay and graft dysfunction. The above parameters were significantly worse in higher fat infiltration group. Also the rejection rate was higher in high group at 1 year post-operation and no significant inter-group difference existed in biliary/vascular complications. In higher group, 4 patients showed graft dysfunctions during perioperative period. Two of them were discharged successfully after secondary transplantation and another 2 patients died. Conclusions On the premise of comprehensive evaluations of donor liver status and reasonable matching of recipients, aged marginal donor liver can be safely applied with excellent clinical outcomes. Severe fatty donor liver should be employed with caution. Hypertensive drugs, high serum sodium and long period of cold ischemia are also important influencing factors for aged donors.

Objective To explore the evaluations and recipient selection methods of extended criteria donor (ECD) kidney donation in the death of citizens and analyze the transplantation outcomes. Methods From January to September 2019, the clinical data of donor-recipients were retrospectively studied. The recipients of ECD donor kidneys not evaluated for kidney zero puncture assessment from January 2014 to July 2016 were group A1 and those receiving standard donor kidney (SCD) belonged to group A2. From August 2016 to March 2019, all DCD donors were routinely evaluated for kidney zero puncture and those receiving ECD recipients fell into Group B1 and those receiving SCD belonged to Group B2. Analysis was performed for ECD/SCD donor renal zero puncture pathological features and lesion degree and utilization of ECD donor kidney; donor-recipient body surface area (BSA) ratio and lesion degree of ECD donor kidney on recipient selecting and matching. Serum creatinine value, perioperative adverse events and 1-year follow-up of human/kidney survival rate in each group were compared at 1 day, 1 week, 1 month, 3 months, 6 months and 1 year. Results A total of 108, 264, 306 and 416 recipients were recruited into A1, A2, B1 and B2 groups respectively. The ECD donor renal utilization rate was 88.5% vs 93.3% during two time periods. According to the 2016 Banff standard, glomerular sclerosis (GS), renal interstitial fibrosis (Ci) and intimal fibrosis thickening (Cv), small arterial intimal hyalinization (ah), tubular atrophy (ct) and acute tubular injury (ati) accounted for more than B1 group than B2 group (P<0.05). The severity of ECD donor kidney disease, BSA ratio <1.1 group and ≥1.1 group 1 week, 1 month, 3 months postoperative blood creatinine value was lower than the former while declining amplitude of blood creatinine was higher. A significant difference existed in the degree of moderate lesions in donor kidney (P<0.05). After 1 year, serum creatinine value of B1 group was lower than that of A1 group (P<0.05). Conclusions The quality of ECD donor kidney is obviously inferior to that of SCD donor kidney. The Banff donor kidney criterion is an effective mode of evaluating the quality of ECD donor kidney. Based upon the extent of Banff's nephropathy, the ratio of donor/recipient BSA is an important selecting method for ECD donors to receive kidneys and recipients, ultimately improving graft utilization and recipient transplantation.
