Abstract:
With the increasing quantity of organ donors and the continual expansion of the definition of extended criteria donor (ECD) livers, the quality of donor liver has become a prominent issue affecting the high-quality development of liver transplantation, which is also the study focus in related fields. Resolving the shortage of organs to the maximal extent and promoting the high-quality development of organ transplantation lead the development direction of organ donation and transplantation in China. In recent years, the application of mechanical perfusion (MP) for the perfusion, preservation, evaluation and repair of donor liver has become a hot topic to improve the quality of liver transplantation within the international community. In this article, according to different conditions of the application of ECD livers in liver transplantation at home and abroad in combination with the research progress on MP in the international community and relevant research experience of our center, the feasibility of establishing an organ intensive care unit (ICU) with integrated organ protection techniques was discussed, aiming to promote the high-quality development of organ transplantation in China and further expand the technical connotation of the "Chinese model" of organ donation and transplantation.

Abstract:
The liver is an "immune-privileged organ". The incidence and severity of acute rejection after liver transplantation are significantly lower than those after the transplantation of other organs. However, postoperative rejection is still relatively common, and standardized immunosuppressive therapy is the key to guarantee the efficacy of transplantation. To further standardize the immunosuppressive therapy and diagnosis and treatment of rejection after liver transplantation, Branch of Organ Transplantation of Chinese Medical Association organized liver transplant experts to summarize the latest research progress at home and abroad, integrate international guidelines and clinical practice and formulate the "Diagnosis and treatment specification for immunosuppressive therapy and rejection of liver transplantation in China (2019 edition)" based upon the application principle and common regime of immunosuppressant, as well as diagnosis and treatment of various types of rejection after liver transplantation.

Abstract:
The Banff conference on allograft pathology (Banff conference) and the establishment of Banff classification on allograft pathology (Banff classification) are milestones in the development of international allograft pathology. At present, all organ transplantation centers around the world routinely perform pathological diagnosis by biopsy of the transplant kidney according to Banff classification. Subsequently, the consensus process and update mode of Banff classification for transplant kidney was quickly extended to transplant heart, lung, liver, pancreas, and small intestine, etc. The Banff conference has not only become a thematic meeting that includes the pathology study and discussion of various transplant organs, but also gradually developed unified diagnostic standard for the biopsy of each transplant organ, which better promoted the accurate diagnosis and treatment of complications after organ transplantation. This article summarized the history of international allograft pathology research, the Banff conference and Banff classification in promoting organ transplantation, which aimed to provide a reference for the smooth development of clinical organ transplantation.

Abstract:
  Objective  To investigate the application prospect of the most extensive genome engineering pig internationally in preclinical xenotransplantation.  Methods  Porcine endogenous retrovirus (PERV) knockout combined with 3 major heterologous antigen gene knockouts and 9 humanized genes for inhibition of complement activation, regulation of coagulation disorders, anti-inflammatory and anti-phagocytosis were transferred into a pig (PERV-KO/3-KO/9-TG) as a donor, and the heart, liver and kidney were obtained and transplanted to 3 Rhesus macaque recipients respectively to establish a preclinical research model of pig-to-Rhesus macaque xenotransplantation. The functional status of xenografts after blood flow reconstruction was observed and the survival of recipients was summarized. The hemodynamics of xenografts were monitored. The change of hematological indexes of each recipient was compared. The histopathological manifestation of xenografts was observed.  Results  After the blood flow was reconstructed, all xenografts showed ruddy color, soft texture and good perfusion. The transplant heart, liver and kidney showed full arterial and venous blood flow and good perfusion at 1 d after operation. The postoperative survival time of heart, liver, and kidney transplant recipients was 7, 26, and 1 d, respectively. The levels of creatine kinase, creatine kinase isoenzyme, and lactate dehydrogenase increased in heart transplant recipient at 1 d after operation, and gradually recovered to near normal levels at 6 d after operation. All indexes increased sharply at 7 d after operation. The level of aspartate aminotransferase increased in liver transplant recipients at 2 d after operation, and the alanine aminotransferase basically returned to normal at 10 d after operation, but the total bilirubin continued to increase. Both aspartate aminotransferase and alanine aminotransferase increased at 12 d after operation, and reached a peak at 15 d after operation. The kidney transplant recipient developed mild proteinuria at 1 d after operation, and died of sudden severe arrhythmia. Histopathology showed that the tissue structure of cardiac and renal xenografts was close to normal, and liver xenografts presented with patchy necrosis, the liver tissue structure was disordered, accompanied by inflammatory damage, interstitial hemorrhage and thrombotic microangiopathy.  Conclusions  PERV-KO/3-KO/9-TG pig shows advantages in overcoming hyperacute rejection, mitigating humoral rejection and coagulation dysregulation. However, whether it can be used as potential donor for clinical xenotransplantation needs further evaluation.

Abstract:
  Objective  To evaluate the effect of erythropoietin (EPO) on the proliferation and migration of bone marrow mesenchymal stem cell (BMSC) in rats.  Methods  The 5th generation BMSCs were divided into the control (without EPO) and 10, 100, 500, 1 000 IU/mL EPO groups. After 24 h and 48 h of culture, the proliferation rate, migration ability and the expression levels of CXCR4 of BMSCs were detected in each group. The 5th generation BMSCs were further divided into BMSC and EPO-BMSC groups. After 48 h of culture, the effect of EPO upon surface markers, directional differentiation and cytoskeleton morphology of BMSCs were evaluated in both groups.  Results  After theco-culture of EPO and BMSCs for 48 h, the proliferation rate and migration ability of BMSCs were significantly enhanced, and the expression level of CXCR4 protein was significantly up-regulated in the 100 IU/mL and 500 IU/mL EPO groups compared with those in the control group (all P < 0.05). However, EPO exerted no effect upon the expression levels of surface markers and directional differentiation ability of BMSCs in the EPO-BMSC group. In the EPO-BMSC group, the fibrous skeleton of most BMSCs was arranged along the long axis in parallel.  Conclusions  EPO can improve the proliferation rate, migration ability and tissue repair capability of BMSCs, probably by promoting the directional homing of BMSCs to injured organs and tissues via up-regulating the expression level of CXCR4.

Abstract:
  Objective  To improve the understanding of Danon disease and the efficacy of heart transplantation by multi-disciplinary team (MDT) pattern.  Methods  Prior to heart transplantation, MDT consultation was performed on one case of Danon disease, an extremely rare X-chromosome dominant genetic disease. The content of consultation included surgical indication, preoperative preparation and postoperative precaution, as well as the role of MDT in the treatment of Danon disease was summarized.  Results  Preoperative echocardiography showed that the patient presented withdilated-phase of hypertrophic cardiomyopathy complicated with heart failure, which was considered as Danon disease with end-stage heart failure. After MDT consultation, the patient received the preoperative treatment including anti-heart failure, reduction of pulmonary artery pressure, intra-aortic balloon pump (IABP) assistance, liver protection, strengthening nutritional support, etc. The patient underwent orthotopic heart transplantation after a suitable donor was matched. The patient developed muscle weakness in the limbs 5 days after operation, which was gradually mitigated after reducing the dose of glucocorticoid. At postoperative 48 days, the patient was discharged in good condition and continually treated with triple immunosuppressive regimen after discharge. Reexamination at postoperative 6 months revealed that the patient was in good health without any abnormality in electrocardiogram and echocardiography images.  Conclusions  Danon disease is extremely rare and MDT pattern may enhance the efficacy and safety of treatment by heart transplantation.

Abstract:
  Objective  To investigate the clinical characteristics and the experience of multi-disciplinary team (MDT) on recurrence of primary hyperoxaluria (PH) type I after renal transplantation.  Methods  One case presenting with unexplained rapid decline of renal allograft function after allogeneic renal transplantation was discussed by MDT. The role of MDT in diagnosing rare hereditary diseases and improving the long-term survival of renal transplant recipients was summarized.  Results  After MDT consultation, the patient was diagnosed with recurrence of PH type I. Routine immunosuppressive regimen was initiated after the exclusion of rejection. The patient was instructed to drink a large quantity of water, and given with high-quality protein and low-phosphorus diet, vitamin B6, calcium and other conservative therapies to actively prevent and treat postoperative complications. The deterioration of renal graft function was delayed. Nevertheless, regular hemodialysis was resumed at 5 months after renal transplantation until the submission date of this manuscript.  Conclusions  Recurrence of PH type I after renal transplantation is relatively rare. The main clinical manifestations are recurrent kidney stones and decreased renal function with multiple complications and poor prognosis. The condition of the patient is consulted by MDT for confirming the diagnosis, determining the optimal treatment scheme, delaying the progression and improving the clinical prognosis.

Abstract:
  Objective  To analyze the dynamic changes and the influencing factors of T lymphocyte subsets in recipients with stable graft status within 1 year after lung transplantation.  Methods  Clinical data of 41 recipients with stable graft status after allogeneic lung transplantation were analyzed. The absolute value and ratio of T lymphocyte subsets in peripheral blood from recipients were measured by flow cytometry before operation, 2 weeks and each month (within 1 year) after operation, respectively. The effects of age, gender, body mass index (BMI), surgical method, incidence of primary graft dysfunction (PGD) after operation, and primary disease upon the absolute values of T lymphocytes were evaluated.  Results  Within 1 year after lung transplantation, the absolute values of CD3+, CD3+CD4+, CD3+CD8+T lymphocytes and CD4+/CD8+ ratio were changed over time (all P < 0.001). Compared with preoperative values, there was no statistical significance in the absolute values of CD3+ and CD3+CD4+T lymphocytes at 12 months after operation (P=0.659, 0.109), whereas the absolute value of CD3+CD8+T lymphocytes was increased (P=0.02) and the CD4+/CD8+ ratio was decreased (P < 0.001). Age, gender, BMI, surgical method and incidence of PGD after operation exerted no significant effect on the dynamic changes of absolute values of CD3+CD4+ and CD3+CD8+T lymphocytes (all P > 0.05). Primary disease before lung transplantation exerted no effect on the changes of CD3+CD4+T lymphocytes, whereas the postoperative absolute value of CD3+CD8+T lymphocytes was higher in recipients with infectious lung diseases (P < 0.05).  Conclusions  The absolute values of CD3+, CD3+CD4+, CD3+CD8+T lymphocytes in recipients with stable graft status after lung transplantation are relatively low in the early stage after lung transplantation, then gradually restore, and stabilize at 6 months after operation. Dynamic changes are not associated with age, gender, BMI, surgical method and incidence of PGD after operation of recipients.

Abstract:
  Objective  To summarize the incidence, diagnostic and therapeutic experience of hepatic sinusoidal obstruction syndrome (HSOS) after liver transplantation.  Methods  Clinical data of 4 patients with HSOS after liver transplantation were retrospectively analyzed. The incidence, clinical manifestations, imaging and pathological characteristics of HSOS after liver transplantation were collected, and the treatment methods and clinical outcomes of patients with HSOS were analyzed.  Results  The incidence of HSOS after liver transplantation was 0.8%(2/239), and the median time of onset was 4.5(1.7, 9.0) months after liver transplantation. The clinical manifestations of HSOS mainly included abdominal distension, ascites, hepatomegaly, increased bilirubin, and renal insufficiency in partial cases. Enhanced abdominal CT scan of 4 patients with HSOS showed uneven spot-like enhancement and the liver histopathological examination mainly showed the signs of hepatic sinusoidal dilatation complicated with congestion. Four patients were administered with an adjusted regime of immunosuppressant by replacing tacrolimus (Tac) with ciclosporin and adding anticoagulant therapy with warfarin. One patient received transjugular intrahepatic portosystemic shunt (TIPS). After treatment, the symptoms of 3 patients were completely relieved, and 1 patient died. One of the 3 surviving patients died from pulmonary infection and gastrointestinal bleeding.  Conclusions  HSOS is a rare and fatal complication after liver transplantation. Timely diagnosis and treatment can avoid the incidence of graft failure and improve clinical prognosis of the patients.

Abstract:
  Objective  To evaluate the diagnostic value of quantitative detection of cytomegalovirus (CMV) DNA from different sources [plasma, sputum and bronchoalveolar lavage fluid(BALF)] for CMV pneumonia after allogeneic hematopoietic stem cell transplantation.  Methods  Clinical data of 405 recipients undergoing allogeneic hematopoietic stem cell transplantation were retrospectively analyzed. Among them, 19 recipients diagnosed with CMV pneumonia were assigned into the CMV pneumonia group, and 229 recipients with CMV viremia alone, 11 recipients without CMV pneumonia who received fiberoptic bronchoscopy and 16 recipients diagnosed with bacterial or fungal pneumonia based on pathogenic evidence receiving sputum culture were assigned into the control A, B and C groups, respectively. The incidence of CMV pneumonia was summarized. The CMV DNA load of specimens from different sources (plasma, sputum and BALF) of recipients with CMV pneumonia was analyzed. The clinical prognosis of recipients with CMV pneumonia was evaluated.  Results  Among 405 recipients undergoing allogeneic hematopoietic stem cell transplantation, 19 cases developed CMV pneumonia, and the overall incidence of CMV pneumonia was 4.7%(19/405). The CMV DNA load in the plasma, sputum and BALF of recipients with CMV pneumonia was higher than those in the control A, B and C groups (all P < 0.05). In the 19 recipients, 12 cases were cured after antiviral treatment and 7 died from treatment failure(3 cases abandoned treatment). The fatality was 37%(7/19).  Conclusions  Quantitative detection of CMV DNA in the plasma, sputum and BALF may increase the diagnostic rate of CMV pneumonia, thereby improving clinical prognosis of recipients undergoing allogeneic hematopoietic stem cell transplantation.

Abstract:
  Objective  To explore the value of ultrasound elastography in the non-invasive monitoring of liver elasticity of stable recipients at different stages after liver transplantation.  Methods  Clinical data of 73 stable recipients after liver transplantation were collected. According to the time after liver transplantation, all patients were divided into the early group (n=25) and medium-to-long group (n=48). In addition, 38 healthy subjects were assigned into the control group. The ultrasound indexes and liver function indexes were statistically compared among each group. The ultrasound elastography indexes of liver and spleen were analyzed, and their correlation with liver function indexes was analyzed.  Results  Compared with the control group, the ultrasound indexes, alanine aminotransferase (ALT), γ-glutamyl transferase (GGT) and alkaline phosphatase (ALP) levels were significantly increased in the early group (all P < 0.05), and the ultrasound indexes in the medium-to-long group were significantly increased, whereas the GGT level was significantly decreased (all P < 0.05). Compared with the early group, the right oblique diameter of liver, ALT, GGT and ALP levels were significantly decreased in the medium-to-long group (all P < 0.05). Compared with the control group, the sound touch elastography (STE) and sound touch quantify (STQ) values of liver and STE value of spleen in the early group and medium-to-long group were significantly increased (all P < 0.05). Compared with the early group, the ultrasound elastography indexes of liver and spleen in the medium-to-long group were remarkably decreased (all P < 0.05). The ultrasound elastography indexes of liver were weakly correlated with the ALT, aspartate aminotransferase (AST) and GGT levels, significantly correlated with ALP level. The STE value of spleen was weakly correlated with the ALP level. The STE value of liver was significantly correlated with the STQ value of liver. The STE and STQ values of liver were weakly correlated with the STE value of spleen.  Conclusions  The characteristics of liver elasticity in stable recipients after liver transplantation are various among different stages. Persistent monitoring of liver elasticity may provide a novelnon-invasive monitoring method during follow-up after liver transplantation.

Abstract:
Massive blood loss and blood transfusion constantly occur in liver transplantation. Over the past two decades, the amount of blood transfusion during the perioperative period has been decreased dramatically along with the continual maturity of liver transplantation techniques. The goal of liver transplantation without blood transfusion has been achieved. Since bleeding and blood transfusion are correlated with poor prognosis after liver transplantation, reducing bleeding and unnecessary blood transfusion has become the key objective during perioperative period of liver transplantation. In this article, adverse effects of allogeneic blood transfusion during perioperative period of liver transplantation, coagulation function monitoring of patients with end-stage liver disease, blood transfusion management of liver transplant recipients and the strategies of reducing perioperative blood transfusion in liver transplantation were summarized, aiming to provide reference for reducing the requirement of blood transfusion during perioperative period of liver transplantation.
