RESUMEN
Inherited metabolic liver disease (IMLD) is a category of liver metabolic diseases caused by genetic disorders. The pathogenesis of IMLD is complex, which primarily comprises the accumulation of harmful metabolic substrates or products caused by specific enzyme defects and energy defects or abnormal deposition caused by abnormal metabolism of glucose, fat and other substances. In recent years, liver transplantation has played an increasingly critical role in the treatment of IMLD with the development of liver transplantation. At present, IMLD has become the second most important indication after biliary atresia in pediatric liver transplantation. Currently, IMLD patients receiving liver transplantation can be divided into two categories: the first category is IMLD complicated with liver disease; Category 2 patients have a normal liver structure but are deficient in related metabolic enzymes. It can not only replace the liver with abnormal structure and function, but also provide normal enzymes required for patients' metabolism, which may improve their quality of life and even save their lives. In this article, common feasible liver transplantation for IMLD, clinical prognosis and surgical procedures of liver transplantation for IMLD were reviewed, aiming to provide reference for liver transplantation for IMLD.
RESUMEN
Posttransplant diabetes mellitus(PTDM)is a prevalent metabolic disorder after solid organ transplantation. As a major risk factor for cardiovascular disease and even death, PTDM shares the same characteristics with T2DM(obesity & insulin resistance, etc.). Immunosuppressants is also a predisposing factor for transplantation.Screening, prevention and management of PTDM should be performed pre-transplantation, peri-operation and during stable period post-transplantation. In recent years, several novel blood glucose monitoring techniques and anti-diabetic agents have been developed for a more precise treatment of PTDM. In the near future, a multi-disciplinary team should be formulated for optimizing the management of PTDM and improving the outcomes of solid organ transplantation recipients.
RESUMEN
Objective:To compare the prognoses of salvage liver transplantation fulfilling the Criteria of Milan, University of California San Francisco(UCSF)and Hangzhou.Methods:Clinical data were retrospectively reviewed for 256 patients with recurrent hepatocellular carcinoma(HCC)undergoing donation after citizen death(DCD)liver transplantation(LT)from January 2015 to October 2019.They were divided into two groups of primary(PLT, n=175)and salvage(SLT, n=81). General profiles, tumor pathological characteristics and postoperative complications of two groups were compared by T-test, rank-sum or χ2 test.Kaplan-Meier method and Log rank test were employed for comparing overall survival rate(OS)and recurrence-free survival rate(RFS)between two groups.In SLT group, 31 cases fulfilled Milan criteria, 45 cases UCSF criteria and 69 cases Hangzhou criteria.OS/RFS of three groups were compared.According to there was downstaging or bridging treatment pre-LT, SLT group was divided into downstaging group(n=32)and non-downstaging group(n=49). OS/RFS of two groups were compared.According to the Rescit1.1 criteria, downstaging group were divided into remission group(n=14)and non-remission group(n=18)and OS/RFS of two groups were compared. Results:The operative durations of PLT and SLT groups were(439.5±74.9)and(475.1±83.4)min respectively.There was significant inter-group difference( P<0.05); However, no significant inter-group difference existed in amount of intraoperative bleeding, blood transfusion, postoperative hospital stay or incidence of postoperative complications(all P>0.05). No significant difference existed in OS/RFS between PLT and SLT groups( P>0.05). No significant difference existed in OS at 1/3/5 years post-SLT among Milan, UCSF and Hangzhou criteria groups(all P>0.05); However, RFS in Milan criteria group at 1/3/5 years post-SLT were 93.5%, 81.7% and 81.7% respectively.They were significantly higher than 68.9%, 59.7% and 59.7% in UCSF criteria group and 78.3%, 58.8% and 55.5% in Hangzhou criteria group(all P<0.05). For patients on downstaging therapy, OS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 73% and 73% respectively, which was significantly higher than 83.3%, 49.4% and 0 in non-Remission group( P=0.042). RFS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 62.5% and 46.9% respectively, which was significantly higher than 52.9%, 0 and 0 in no-Remission group( P=0.001). Conclusions:The survival outcome of SLT recipients is similar to that of PLT recipients.The overall survival of SLT recipients shows no significant difference between Milan, UCSF and Hangzhou criteria.However, SLT recipients fulfilling Milan criteria have the longest recurrence-free time.The prognosis of patients with remission after preoperative descending treatment is superior to that of patients without remission.
RESUMEN
Objective:To explore the effect of pre-transplant immunotherapy on the prognosis of transplant recipients with hepatocellular carcinoma(HCC).Methods:From June 2018 to September 2021, retrospective analysis was conducted for clinical data of 19 HCC-liver transplant recipients receiving pre-transplant immunotherapy in affiliated Huashan Hospital of Fudan University. Pre-transplant immunotherapy regimen, adverse reactions, post-transplant acute rejection, tumor recurrence and metastasis and other complications were recorded. According to the preoperative tumor imaging and the changes of alpha-fetoprotein level, tumor change during recipient waiting period was judged by the mRECIST standard. According to whether or not there was partial tumor remission, they were divided into two groups of non-remission( n=13)and remission( n=6). Postoperative conditions of two groups were compared. Kaplan-Meier method was used for calculating the survival rate of recipients after transplantation and survival curve and Log-rank test utilized for comparing the recurrence-free and overall survival rates of recipients at 1 and 2 years post-operation. Results:A total of 19 liver transplant recipients received immunotherapy plus targeted and transcatheter arterial chemoembolization(TACE) before transplant. In non-remission group, tumor was stable( n=9)and progressive( n=4); 6 cases in remission group had tumor partial remission. Two recipients in non-remission group were pathologically confirmed by liver biopsy to have acute rejection(2/19, 10.5%)and both recovered after glucocorticoid + rATG and glucocorticoid therapy. In non-remission group, 2 patients died from septic shock post-operation. Among 3 patients of tumor recurrence and metastasis post-operation, 2 cases survived with tumor and 1 died after tumor recurrence and metastasis. In remission group( n=6), none had postoperative tumor recurrence and metastasis. The recurrence-free survival rates of non-remission group recipients at 1 and 2 years post-operation were 76.9% and 76.9% and recurrence-free survival rates in remission group were 100% and 100% respectively and inter-group difference in RFS was not statistically significant( χ2=1.468, P=0.226). The overall survival rates of recipients in non-remission group at 1 and 2 years post-operation were 76.9% and 76.9% respectively. And recipients in remission group were 100% and 100% respectively and no statistically significant inter-group difference existed in OS( χ2=1.292, P=0.256). Conclusions:Without a significantly higher risk of acute rejection after transplant, immunotherapy may be an effective option for bridging treatment before liver transplantation for HCC. And it remains necessary to expand the sample size for verifications and supports.
RESUMEN
Objective:To explore the relationship between CD24 expression in preoperative peripheral blood as well as cancer tissue and clinical parameters and prognosis in patients with hepatocellular carcinoma (HCC) after liver transplantation (LT).Methods:From November 2018 to November 2019, clinical data were collected for 65 HCC patients and 41 patients with benign liver disease.The preoperative peripheral blood level of CD24 was detected by enzyme-linked immunosorbent assay (ELISA) and the expression of CD24 in cancerous foci and adjacent tissues examined by immunohistochemistry.Kaplan-Meier survival curves of differential CD24 expression were plotted and survival differences compared by Log-rank method.One-way ANOVA was utilized for examining the relationship between the expression level of CD24 and various clinicopathological parameters and multivariate Cox analysis for screening independent risk factors affecting patient prognosis.Results:The concentration of CD24 in preoperative peripheral blood (p-CD24) of HCC patients (6.51±2.33 μg/L) was significantly higher than that of patients with benign liver disease (4.10±0.91) μg/L, P<0.05.The positive rate of CD24 was obviously higher in cancerous tissues than that in adjacent tissues (87.7% vs. 4.6%, P<0.05). The peripheral blood level of CD24 was positively correlated with the expression intensity of CD24 in tumor tissues (t-CD24, r=0.570, P<0.001). The expression of CD24 (both in blood and cancer foci) was significantly correlated with preoperative level of gamma-glutamyl transferase (GGT), maximal tumor diameter, microvascular invasion, portal vein tumor thrombus, vessel carcinoma embolus and satellite focus ( P<0.05). The expression of CD24 in patients exceeding the Milan/UCSF criteria was higher than those fulfilling the criteria ( P<0.005). Patients with a higher expression of CD24 had worse overall survival and recurrence-free survival rates as compared to those a lower expression of CD24 ( P<0.05). Multivariate Cox analysis indicated that t-CD24 [OS: HR=3.661(1.005-13.333)], P=0.049; recurrence-free survival (RFS): [HR=4.331(1.887-9.942), P=0.001] and preoperative level of alpha fetoprotein (AFP) [OS: HR=4.900(1.590-15.097), P=0.006]; RFS: [HR=3.414(1.614-7.221), P=0.001] were independent risk factors for overall survival and recurrence-free survival in HCC patients undergoing LT. Conclusions:The preoperative peripheral blood level of CD24 in HCC patients undergoing LT indirectly reflects the expression of CD24 in cancerous tissues to a certain extent.And the expression of CD24 in cancerous tissue is one of the independent risk factors affecting OS and RFS of LT patients.
RESUMEN
Objective:To investigate the imaging anatomical features of donor liver blood vessels in laparoscopic left lateral donor liver acquisition and their clinical significance.Methods:The retrospective and descriptive study was conducted. The clinical data of 39 living donor liver transplantation (LDLT) donors who were admitted to Huashan Hospital Affiliated to Fudan University between October 2016 and December 2018 were collected. There were 10 males and 29 females, aged (31±7)years. The clinical data of 39 LDLT recipients were collected. There were 26 males and 13 females, aged 8 months (range, 4-68 months). Abdominal enhanced computed tomography and three-dimensional vascular reconstruction were performed on donors to evaluate the anatomical characteristics of hepatic vessels. All the donors underwent laparoscopic left lateral donor liver acquisition. Observation indicators: (1) three-dimensional vascular reconstruction of preoperative imaging; (2) surgical conditions; (3) follow-up. Follow-up was performed using outpatient examination to detect complications of recipients after LDLT up to October 2019. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was analyzed by the t test. Measurement data with skewed distribution were represented as M (range). Count data were expressed as absolute numbers or percentages. Results:(1) Three-dimensional vascular reconstruction of preoperative imaging: the anatomical characteristics of hepatic artery and hepatic vein revealed by three-dimensional vascular reconstruction of preoperative imaging of 39 donors included ① middle hepatic artery was present in 11 donors, among which 5 started from the right hepatic artery, 3 from the confluence of the right and left hepatic artery, and 3 from the left hepatic artery. Two donors had anatomical variation in the left hepatic artery which was presentation of left accessory hepatic artery originated from the left gastric artery. The other 26 donors had no middle hepatic artery or anatomical variation in the left hepatic artery. ② The left hepatic vein and the middle hepatic vein of 9 donors were respectively drained into the inferior vena cava. Seven donors had the left upper branch of the left hepatic vein, and 23 donors had a joint trunk of the left hepatic vein and the middle hepatic vein which drained into the inferior vena cava. (2) Surgical conditions: ① all the 39 donors successfully underwent laparoscopic left lateral donor liver acquisition. The operation time and volume of intraoperative blood loss were (160±32)minutes and (142±74)mL. ② Of 11 donors with middle hepatic artery, left hepatic artery was the dominant artery in 8 donors and was used for hepatic artery anastomosis and reconstruction in liver transplantation, middle hepatic artery started from left hepatic artery in 3 donors and the joint trunk of left and middle hepatic artery was used for hepatic artery anastomosis and reconstruction in liver transplantation. Of 2 donors with anatomical variation in the left hepatic artery, one had left accessory hepatic artery as the dominant artery and the other had left hepatic artery as the dominant artery. Left accessory hepatic artery and left hepatic artery were respectively used for hepatic artery anastomosis and reconstruction in liver transplantation. The other 26 donors had left hepatic artery for hepatic artery anastomosis and reconstruction in liver transplantation. ③ Among the 39 donors, 11 received intraoperative left hepatic vein preferred approach and 28 received intraoperative non-left hepatic vein preferred approach. The operation time and volume of intraoperative blood loss of donors with left hepatic vein preferred approach were (147±22)minutes and (110±44)mL, respectively, versus (169±33)minutes and (154±81)mL of donors with non-left hepatic vein preferred approach, showing significant differences in the above indicators between the two groups ( t=4.19, 2.81, P<0.05). (3) Follow-up: 39 donors were followed up for 10 months. During the follow-up, there was no hepatic artery anastomotic bleeding, stenosis, ischemic bile duct injury and biliary stenosis caused by poor hepatic arterial blood supply, or any complications related to hepatic venous outflow tract stenosis. Conclusions:Three-dimensional vascular reconstruction before laparoscopic left lateral donor liver acquisition can reveal the anatomical variation of middle hepatic artery and left hepatic artery, which can guide the selection of surgical approach. The left hepatic vein preferred approach is recommended for the qualified donor in the laparoscopic left lateral donor liver acquisition, which can shorten the operation time and reduce the volume of intraoperative blood loss.
RESUMEN
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.
RESUMEN
Objective To explore the postoperative psychological status of donors during pediatric living donor liver transplantation (LDLT) to elucidate the correlation between resilience,anxiety and depression.Methods Random sampling was employed for selecting 60 pediatric LDLT donors undergoing LDLT from September 2014 to February 2019.They were requested to answer a questionnaire.The questionnaire concluded general information,self-rating anxiety scale (SAS),selfrating depression scale (SDS) and Chinese version of Resilience Scale.Results The score of anxiety was (46.06 ± 10.06) and depression was (50.32 ± 11.49).Both values were higher than those of Chinese norm.The score of resilience was (59.55 ± 14.62).And the total score of resilience and the score of each dimension were negatively correlated with anxiety and depression (P<0.01).Conclusions The postoperative anxiety and depression level of donors during LDLT are higher than the ordinary.Resilience is negatively correlated with the level of anxiety and depression.The lower level of resilience,the higher anxiety and depression of donors during LDLT.For clinicians,appropriate intervention measures should be taken for improving the resilience,reducing negative emotions and boosting the quality-of-life of donors during LDLT.

RESUMEN
Objective To summarize the screening Methods for human parvovirus (HPV) B19 infection after liver transplantation and analyze the related risk factors. Methods Clinical data of 86 recipients were retrospectively analyzed. According to the Results of next generation sequencing (NGS), all recipients were divided into the HPV B19 infection group and control group. Clinical characteristics, treatment regime and clinical prognosis of patients infected with HPV B19 were analyzed. The risk factors of HPV B19 infection were analyzed using univariate and multivariate Logistic regression model by forward LR step method. Results Nine of the 86 recipients developed fever and progressive anemia with unexplained reasons at approximately 2 weeks after liver transplantation. NGS detection demonstrated that HPV B19 was positive and they were diagnosed with pure red cell aplasia (PRCA) caused by HPV B19 infection. After intravenous immunoglobulins (IVIG) was given and the immunosuppressant therapy was adjusted, the hemoglobin levels in all patients were significantly increased. The Results of multivariate analysis revealed that low serum globulin level in peripheral blood at postoperative 7 d [odds ratio (OR) =0.749, P=0.040] and young age (OR=0.937, P=0.038) were the independent risk factors of HPV B19 infection after liver transplantation. Conclusions HPV B19 infection should be considered in relatively young patients with unexplained hemoglobin decline early after liver transplantation. NGS screening is an effective method for early diagnosis of HPV B19 infection. Low serum globulin level in peripheral blood at postoperative 7 d and young age may be independent risk factors of the incidence of HPV B19 infection.

RESUMEN
Objective To investigate the clinical efficacy and therapeutic progress of orthotopic liver transplantation for the treatment of hepatic epithelioid hemangioendotheliom(a EHE). Methods Clinical data of 2 patients diagnosed with hepatic EHE were retrospectively analyzed. One patien(t case 1) was diagnosed with multiple hepatic EHE complicated with multiple infarction lesions of the spleen, and underwent orthotopic liver transplantation combined with splenectomy. The other cas(e case 2) was diagnosed with multiple hepatic EHE and received orthotopci liver transplantation alone. Literature review was performed. Pathological characteristics, clinical efficacy of liver transplantation and clinical prognosis of hepatic EHE patients were analyzed. Results Two patients successfully underwent surgery and were discharged postoperatively. The diagnosis of hepatic EHE was confirmed by pathological examinaiton and case 1 was complicated with EHE of the spleen . For case 1, tacrolimus was replaced by sirolimus at postoperavtie 1 month. At postoperative 4 months, capecitabine was orall y administered( chemotherapy) for EHE recurrence. At 6 months after surgery, the patient wa sdiagnosed with recurrent hepatic EHE complicated with multiple bone metastases, and waso rally administered with sorafenib. At postoperative 7 months, the patient died from cachexia and liver failure. Case 2 was followed up until the submission date( 8 months after surgery). No postoperative complications and tumor recurrence were observed. Previous studies had demonstrated that surgical resection was the primary therapy of hepatic EHE. Liver transplantation was highly recommended for patients with multiple unresectable hepatic EHE and extra-hepatic lesions. Moreover, chemotherapy, percutaneous puncture combined with transcatheter arterial chemoembolization and anti-angiogenesis treatment exerted certain clinical efficacy.C onclusions Surgical resection remains the primary therapy of hepatic EHE. For patients with multiple intrahepatic EHE, liver transplantation is considered as the optimal treatment. Much attention should be diverted to the prevention and treatment o f recurrent hepatic EHE following liver transplantation, aiming to improve the clinical efficacy.
RESUMEN
Objective To investigate the prognosis of patients underwent liver transplantation (LT) for end-stage autoimmune liver disease (AILD). Methods Clinical data of 48 patients with end-stage AILD undergoing LT from May 1996 to April 2013 in Affiliated Changzheng Hospital of the Second Military Medical University were analyzed retrospectively. The postoperative cumulative survival rates of the recipients were calculated,and the cause of death was analyzed. The postoperative rejections,new-onset viral hepatitis and AILD recurrence were analyzed. Results In 48 AILD recipients,38 cases survived and the postoperative 5-year cumulative survival rate was 76%. Causes of death for the 10 dead cases were multiple organ failure, liver graft failure,sepsis,pulmonary infection,hemorrhage,hepatic artery embolization and renal failure. In 48 AILD recipients,9 cases (19%) suffered acute rejection after operation,3 cases suffered new-onset hepatitis B infection in 1-2 years after operation,2 recipients suffered primary disease (primary biliary cirrhosis)recurrence 2 years after operation and all survived for a long term after positive treatments.Conclusions Most liver transplant recipients with end-stage AILD can obtain a long-term survival. Attentions should be paid on the immunosuppressive regimens in early period after LT,prevention of infection,rejection and postoperative new-onset viral hepatitis,timely diagnosis of primary disease recurrence.
RESUMEN
Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. <br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. <br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P<0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP<0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P<0.05). <br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.
RESUMEN
Objective To explore the relationship between peripheral differential blood count and ATP value in Cell CD4 + T tested by ImmuKnow method in liver transplants. Methods In this study 49recipients after classic orthotopic liver transplantation (OLT) were enrolled. In a period from two weeks to two months after transplantation when all were free of glucocorticoid. Blood were sent for WBC differential samples count and ATP value in Cell-CD4 + T tested by ImmuKnow method via SPSS17. 0 software. Five more samples were selected randomly for duplicated testing of the indices in Week2, 3, 4,6 and 8 after the transplanting operation to further verify the relativity. Results White blood cell count has the highest relativity with ImmuKnow ATP value at 0. 821. The 5 recipients were repeatedly tested for ImmuKnow ATP values that were found positively correlated to cell count with a coefficient of over 0. 5. Conclusions The peripheral leukocyte count in early stage after liver transplantation is in positive correlation with ATP value in Cell CD4 + T, and the changes of numeration of leukocyte reflect changes of ATP value.
RESUMEN
Objective To explore the monitoring and the individualized adjustment of cellular immunology function in the recipients infected with pan-drug resistant Acinetobacter baumannii(PDR-Ab)after liver transplantation.Methods We retrospectively summarized the infection and the prognosis of PDR-Ab in 299 cases of liver transplantation performed from Jan.2008 to May 2010.The absolute number of T lymphocytes and ATP level within CD4+ T cells were monitored,and T cell immunology function(TCIFS)was scored.According to different immunology adjusting proposals,14 cases of PDR-Ab infection were divided into 2 groups:(1)traditional group,routine anti-infective therapy;(2)individualized group.Individualized immunology adjustment was made according to the score of TCIFS besides routine therapy.Results There was no significant difference in age,MELD and Child-pugh score between two groups.The peri-operative bleeding volume in individualized group was more than that in traditional group(P<0.01).There was no significant difference in TCIFS score between two groups at 1st week after transplantation and the onset of the PDR-Ab infection.However,the score in individualized group was apparently higher than that in traditional group when anti-infection therapy ended(P<0.05).The difference in the recovery rate between two groups was significant(P<0.05).No rejection happened in two groups.Conclusion It is an effective way to decrease the mortality of PDR-Ab infection after liver transplantation that the individualized adjustment of immunosuppression protocols is guided by grading quantitatively the cellular immunology function according to the absolute number of T lymphocytes and ATP level within CD4+ T cells.
RESUMEN
Objective To explore the dynamic changes of the cellular immune function in severe infection after liver transplantation, and to guide the individualized immunology adjustment. Methods 378 cases of livertransplantation were analyzed retrospectively. Seventy-four cases (infection group) suffered serious infection, including 54 cases cured (cure group), 20 cases died (death group). Fifty cases without infection and rejection were randomly selected as control group (stable group). According to the individualized adjusting proposal of immunosuppressants, 74 patients with severe infection were divided into two groups: traditional (T) group and individualized (Ⅰ) group. The general condition, recovery rate and change of cellular immune function pre- and post-treatment were analyzed. Results The preoperative MELD score and the intraoperative blood loss in infection group were significantly higher than stable group, and those in death group were higher than in cure group. CD4+ T lymphocyte counts and lymphocyte counts in stable group were increased significantly from first week post-operation to discharge. The two indicators in infection group at first week postoperation and the onset of infection were lower than in stable group (P<0. 01). In cure group after infection was controlled the two indicators were higher than at first week post-operation and the onset of infection (P<0. 01), while in death group they were reduced up to death (P<0. 05). There was no significant difference in age, preoperative MELD score and the immune function indicators both at first week post-operation and the onset of infection between T group and Ⅰ group, except the intraoperative blood loss in Ⅰ group was greater than in T group. The recovery rate in Ⅰ group (90. 5 %)was higher than in T group (66.0 %). Conclusion Individualized adjustments of immunosuppressants guided according to the dynamic changes of cellular immune function helped to improve the prognosis of severe infection after liver transplantation.

Objective: To explore the apoptosis-inducing effect of salvianolate on hepatoma SMMC-7721 cells and the underlying mechanism. Methods: SMMC-7721 cells were co-cultured in vitro with different concentrations (0.5, 1, 2 mg/ml) of salvianolate for 24 h. The apoptotic SMMC-7721 cells were examined by flow cytometry, and the changes of mitochondrial transmembrane potential were examined by mitochondrial transmembrane potential JC-1 kit. The activities of caspase-8, caspase-9, and caspase-3 were detected by spectrophotometry in the hepatoma SMMC-7721 cells after co-cultured with 1 mg/ml salvianolate. The changes of apoptotic SMMC-7721 cells induced by salvianolate in the presence or absence of caspase-9 inhibitor or caspase-3 inhibitor were measured by flow cytometry. The expressions of pro-apoptotic protein Bax and anti-apoptotic protein Bcl-2 were detected by Western blotting analysis. Results: Salvianolate significantly induced apoptosis of hepatoma SMMC-7721 cells (P<0.05), and the decline of mitochondrial membrane potential increased with the increase of salvianolate concentration (P<0.05). The activities of caspase-9 and caspase-3, but not caspase-8, were increased in hepatoma cells after treatment with 1 mg/ml salvianolate for 24 h (P<0.05). The apoptosis-inducing effect of salvianolate was significantly decreased in the presence of caspase-9 or caspase-3 inhibitors (P<0.05). Western blotting results showed that salvianolate increased pro-apoptotic protein Bax expression and decreased anti-apoptotic protein Bcl-2 expression. Conclusion: Salvianolate can induce the apoptosis of human hepatoma SMMC-7721 cells in a dose-dependent manner, which is probably mediated by mitochondrial apoptosis pathway.
RESUMEN
Objective To explore the relationship between ATP content in CD4+ T lymphocytes and acute rejection after liver transplantation(LT). Methods This study contained 77 patients who received LT from February to October 2009, They were divided into AR (acute rejection) and NAR (non-acute rejection) groups while 56 healthy people were enrolled to serve as the control group.Blood specimens were collected preoperatively and at 1, 2 and 4 weeks postoperatively. For the AR group, specimens were also collected on the day when AR occurred and 1 week after steroid bump together with that of the healthy people. ImmuKnowTM test kits for immune cell function were used to assay the ATP value. Results ATP values within CD4+T lymphocytes were elevated significantly in each group compared with those preoperatively. Peak level was reached in the AR group and was significantly higher than that of the contemporary NAR group (P<0.05). ROC curve analysis showed that the obvious elevation of the ATP value within CD4+ T lymphocytes 1 week postoperatively had better sensitivity and specificity in diagnosing AR. The ATP sensitivity rate for early AR was 84.6 %and specificity rate 81 %. The ATP value within CD4+ T lymphocytes on the day of AR occurrence had a positive relationship with the rejection acting index(RAI), while relative index (r) was 0. 876(P<0.05). After the steroid dump treatment, AR in all the patients was reversed and the ATP value declined significantly as compared with the control group and the day when AR occurred(P<0. 05).Conclusion During the postoperative period, the dynamic change of ATP value within CD4 + T lymphocyte had a close relationship with acute rejection after liver transplantation. Thus, it might be used as a feasible and noninvasive monitoring index for diagnosing AR and the effectiveness of the anti-rejection treatment.
