Objective:To investigate the predictive value of preoperative γ-glutamyl transferase/lymphocyte count ratio (GLR) levels for postoperative tumor recurrence in liver transplant recipients with liver cancer.Methods:The clinical data of 158 recipients who were diagnosed with hepatocellular carcinoma (hereinafter referred to as liver cancer) and received liver transplantation at the No. 900 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2008 to October 2022 were retrospectively analyzed. X-tile software, the Kaplan-Meier method, univariate and multivariate Cox regression, and other statistical methods were performed. The predictive value of preoperative GLR levels for postoperative tumor recurrence in liver transplant recipients with liver cancer and the risk factors for tumor recurrence in liver cancer patients post-liver transplantation were analyzed.Results:The X-tile software analysis confirmed that 96.8 was the optimal cutoff value for the preoperative GLR level to predict recurrence. The grouping threshold for survival analysis using the GLR cutoff value was 96.8. The tumor recurrence rates at 1, 3, and 5 years after surgery in the low-level GLR group (90 cases) and the high-level GLR group were 19.3% vs. 44.2%, 31.8% vs. 60.0%, and 34.1% vs. 62.9% (68 cases), respectively, and the differences were statistically significant between the two groups ( P<0.05). The Kaplan-Meier survival curve analysis results showed that the overall postoperative survival rate and recurrence-free survival rate were significantly lower in the high-level GLR group than the low-level GLR group ( P<0.05). The univariate Cox analysis result showed that there were statistically significant differences in preoperative aspartate aminotransferase, alpha fetoprotein, surgery time, maximum diameter of a solitary tumor, presence or absence of microvascular invasion, presence or absence of portal vein tumor thrombus, and preoperative GLR levels between the two groups ( P<0.05). Multivariate Cox analysis results showed that preoperative alpha-fetoprotein ≥400 ng/ml, GLR≥96.8, and the maximum diameter of a solitary tumor ≥5.0 cm were independent risk factors for postoperative tumor recurrence in liver transplant recipients with liver cancer ( P<0.05). Conclusion:GLR levels have a certain predictive value for postoperative tumor recurrence in liver transplant recipients with liver cancer. Furthermore, the postoperative tumor recurrence rate is relatively high when the preoperative GLR level in liver transplant recipients with liver cancer is ≥96.8.

Hepatolenticular degeneration is kind of an autosomal recessive genetic disease with diverse, complex and non-specific clinical manifestations, high misdiagnosis rate, rapid disease progression, poor drug treatment effect, and high mortality. It is one of the rare several genetic metabolic diseases in clinic that could be cured by liver transplantation method. Liver transplantation provides healthy P-type ATP enzyme through the donor liver, which can correct its genetic defects, improve copper metabolism disorders, relieve clinical symptoms, improve the quality of life, and improve the survival rate of patients. Liver transplantation is playing an increasingly important role as an important means to treat hepatolenticular degeneration. With the rapid development of partial living donor liver transplantation, auxiliary liver transplantation, domino-assisted liver transplantation and cross-assisted domino liver transplantation, a new way has been provided for patients with hepatolenticular degeneration, alleviating the problem of donor liver shortage and shortening the waiting time of recipients, which has certain clinical value and development prospects. In this paper, a review of the research progress in the treatment of hepatolenticular degeneration with liver transplantation was made with reference to the relevant literature at home and abroad.

A 24-year-old male patient was admitted to the Organ Transplant Department of the 900th Hospital of the Joint Logistic Support Force on March 13, 2000, due to repeated abdominal distension accompanied by edema of both lower limbs for more than 7 months and aggravated for 1 month. Clinical diagnosis: hepatolenticular degeneration, metabolic encephalopathy, decompensated stage of cirrhosis. Orthotopic liver transplantation was performed under general anesthesia on March 24, 2000. The postoperative recovery is smooth, and the patient has survived for more than 23 years, with normal life and work.

Objective:To investigate and analyze the clinical efficacy of salvage liver transplantation (SLT), rehepatectomy (RH), local ablation (LA), and prognostic risk factors in patients with postoperative recurrence of hepatocellular carcinoma.Methods:Clinical data of 145 patients with recurrent liver cancer in the 900th Hospital of the Joint Logistics Support Force of the People's Liberation Army from January 2005 to June 2018 were retrospectively collected. SLT group, RH group, and LA group included 25, 44, and 76 cases, respectively. Follow-up and statistics were recorded on the overall survival rate, relapse-free survival rate, and complications of the three groups of patients at 1, 2, and 3 years after surgery. Univariate and multivariate COX analyses were used to analyze the prognostic risk factors in patients with recurrent HCC.Results:The overall survival rates of 1, 2, and 3 years following surgery in the SLT, RH, and LA groups were 100.0%, 84.0%, 72.0%, 95.5%, 77.3%, 65.9%, 90.8%, 76.3%, and 63.2%, respectively, when the recurrence of liver cancer met the Milan criteria. The overall survival rate did not differ statistically between SLT and RH ( P = 0.303) or between RH and LA ( P = 0.152). There were statistically significant differences in recurrence-free survival between SLT and RH or RH and LA ( P = 0.046). There was no statistically significant difference in the incidence of complications between SLT and RH or RH and LA ( P > 0.017). Age > 65 years was an independent risk factor affecting the overall survival rate in patients with recurrent HCC. Age > 65 years and recurrence time < 24 months were independent risk factors affecting the recurrence-free survival rate in patients with recurrent HCC. Conclusion:SLT is the best treatment option when the recurrence of HCC meets Milan's criteria. RH and LA are the appropriate treatment plans for recurrent HCC when the liver source is limited.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.

Objective:To investigate the predictive effect of neutrophil to lymphocyte ratio (NLR) for recurrence-free survival after liver transplantation in hepatocellular carcinoma (HCC) patients.Methods:The clinical data of 84 HCC patients who underwent liver transplantation in the 900th Hospital of the Joint Logistics Team, PLA, from January 2012 to December 2019 were included in this retrospective analysis. There were 73 males and 11 females, with an average age of 51 years. Univariate and multivariate Cox regression analyses were performed. The distinguishing ability of NLR for predicting recurrence-free survival in patients with HCC after liver transplantation was analyzed using the receiver operating characteristic (ROC) curvee. The two groups were generated according with the cut-off value, and the recurrence-free survival time to make the Kaplan-Meier survival curve.Results:The area under the ROC curve of NLR for predicting recurrence-free survival after liver transplantation in patients with HCC was 0.683, Yoden index was 0.319, and the optimal threshold was 3.2.Univariate analysis showed that maximum tumor diameter, number of tumors, Milan criteria, and NLR were associated with recurrence-free survival after liver transplantation in patients with HCC (all P<0.05). Multivariate analysis showed that maximum tumor diameter ( HR=2.412, 95% CI: 1.277-4.555), number of tumors ≥3 ( HR=5.595, 95% CI: 2.023-17.531) and NLR≥3.2 ( HR=2.891, 95% CI: 1.348-6.204) were independent risk factors for recurrence-free survival of HCC patients prediction after liver transplantation (all P<0.05). The 1-year recurrence-free survival rate was 78% in the NLR<3.2 group ( n=61), which was superior to 58% in the NLR≥3.2 group ( n=23), and the difference was statistically significant ( P<0.05). Conclusion:Tumor diameter, number of tumors and NLR are risk factors affecting the prognosis of liver transplantation in patients with HCC, and high serum NLR may indicate recurrence-free survival in patients with HCC after liver transplantation.

Objective To investigate the feasibility of liver transplantation in the treatment of inoperable hilar cholangiocarcinoma. Methods The clinical data for 3 patients with unresectable hilar cholangiocarcinoma who underwent liver transplantation in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of People's Liberation Army from January 2006 to December 2012 were retrospectively analyzed. The patients were followed up by phone, outpatient service, and hospitalization. The starting point of the follow-up was the operation date. The patients death was the end point. The clinical and pathological features, postoperative survival, tumor recurrence, and prognostic factors were observed. The follow-up deadline was December 2017. Results All 3 patients underwent classical orthotopic liver transplantation using retrograde perfusion through inferior vena cava and no perioperative deaths occurred. All 3 patients were followed up for 10 to 132 months. During the follow-up period, of 1 patient who died of tumor recurrence, the pathological TNM stage was T4a N1 M0, and both had Union for International Cancer Control stage Ⅳa, and the tumor-free survival time was 3 months, and the survival time was12 months. Of 1 patient who died of other causes, the pathological TNM stage was T3N1 M0, and both had Union for International Cancer Control stage Ⅲ, and the tumor-free survival time was 12 months, and the survival time was12 months. One case as of the end of follow-up, the patient has survived for 132 months, the pathological TNM staging was T2a NOM0, and both had Union for International Cancer Control stage Ⅱ. Conclusions Lymph node positive and high pathological TNM stage were poor prognosis factor for hilar cholangiocarcinoma who underwent liver transplantation. Patients with early hilar cholangiocarcinoma who don't have lymph node metastasis are expected to benefit from liver transplantation.

Objective To investigate the biliary complications and recovery of liver function after liver transplantation from citizen's deceased donors (DCD) versus standard criteria donors (SCD).Method The clinical data of 269 patients who underwent orthotopic liver transplantation from January 2009 to December 2016 at the Fuzhou General Hospital were collected.197 livers were from SCD and 72 from DCD.Propensity score matching (PSM) was used to compare the biliary complications and recovery of liver function after liver transplantation in the two groups.Results PSM matched 61 pairs of patients.There were 10 (16.4％) and 8 (13.1％) biliary complications in the DCD and the SCD groups,respectively,with no significant difference between them (P ＞ 0.05).The recovery of liver function was significantly delayed in the DCD group when compared with the SCD group.The levels of ALT,AST,GGT and AKP in the DCD group were significant different on the postoperative first,third,fifth,seventh and fourteenth day (P ＜ 0.05).At 30 days after surgery,there was no significant difference in liver function between the two groups.Conclusions Liver grafts from DCD had a significant impact on the recovery of liver function.When compared with the SCD group,the DCD group recovered significantly slower in liver function.There was no significant increase in the incidence of biliary complications.

Objective To investigate the expression of long-chain non-coding RNA gastric cancer high expression transcription factor 1 (GHET1) in hepatocellular carcinoma (HCC) and the correlation with prognosis,cell proliferation,migration and invasion.Methods 20 HCC patients who underwent surgery from Fuzhou General Hospital of Chinese People's Liberation Army from March to May 2016 were included.The HCC tissue and adjacent normal tissue of 182 patients from June 2012 to December 2013 were retrospectively collected.According to the median value of GHET1 expression,it was divided into GHET1 high expression group and low expression group,91 cases each.Huh7 and HepG2 cells were divided into:blank control group (Con) with serum-free medium,siRNA-GHET1 group transfected with siRNA-GHET1,and negative control group (siRNA-NC) transfected with negative control sequence.The expression of GHET1 was detected by real-time fluorescence quantitative polymerase chain reaction,and the effect of GHET1 on HCC cells was analyzed by CCK-8,Transwell assay and Western blot.Results Compared with adjacent normal tissue,the relative expression of GHET1 mRNA in HCC tissues was significantly increased.Compared with LO2 cells,the mRNA expression of GHET1 in Huh7 and HepG2 cells was higher (P＜0.05).The GHET1 high expression group had tumor＞5 cm,vascular invasion,AFP＞400 μg/L,Edmonson grade Ⅰ,and the tumor-free ratio was lower in the expression group (P＜0.05).Survival analysis showed that HCC patients with high GHET1 expression had a poorer prognosis than patients with low expression.Multivariate Cox regression analysis showed that high expressed GHET1,vascular invasion (HR=2.067,95％ CI:1.350 to 3.162),and without tumor capsule are independent predictors of recurrence in HCC patients.After transfection with Huh7 and HepG2 cells,the proliferation of siRNA-GHET1 group was significantly decreased comparing with Con and siRNA-NC groups.Compared with siRNA-NC group,the migration and invasion ability of siRNA-GHET1 group decreased,and E-cadherin expression increased.The expression of fibronectin and vimentin decreased,and the difference was statistically significant (P＜0.05).Conclusions The expression of GHET1 in HCC tissue is higher comparing with normal tissue,which increases the proliferation,migration and invasion of hepatoma cells.It is an independent predictor of prognosis in HCC patients and a potential target for clinical treatment.

Objective To evaluate the value of preoperative model for end-stage liver disease combined with serum sodium (MELD-Na) score for the prediction of the incidence of acute kidney injury (AKI) early after liver transplantation. Methods Clinical data of 315 recipients undergoing orthotopic liver transplantation by retrograde inferior vena caval perfusion were retrospectively analyzed. According to preoperative MELD-Na score, all patients were divided into group A (MELD-Na score≤10, n=115), group B (1020, n=82). Preoperative and intraoperative parameters of the recipients were statistically compared among three groups. Preoperative parameters included serum creatinine (Scr), blood urea nitrogen (BUN), albumin (Alb), total bilirubin (TB), prothrombin time-international normalized ratio (PT-INR), mean arterial pressure (MAP) and serum Na+,etc. Intraoperative parameters included operation time, vena caval occlusion time, hemorrhage volume, quantity of red blood cell infusion, quantity of plasma transfusion and total fluid infusion volume, etc. The incidence and staging of AKI early after liver transplantation in the recipients were statistically compared among three groups. Spearman's rank correlation analysis was performed to analyze the correlation between preoperative MELD-Na score and AKI staging. Results Preoperative BUN, Alb, TB, PT-INR, MAP and Na+ in the recipients significantly differed among three groups (all P<0.05). Intraoperative vena caval occlusion time, hemorrhage volume, quantity of red blood cell infusion and quantity of plasma transfusion significantly differed among three groups (all P<0.05). In 315 recipients undergoing liver transplantation, the incidence of AKI within postoperative 1 week was 64.8% (204/315), and 43% (49/115), 71% (84/118) and 87% (71/82) in group A, B and C. Statistical significance was identified among three groups (all P<0.05). Spearman's rank correlation analysis revealed that preoperative MELD-Na score was positively correlated with AKI staging (r=0.442, P=0.000). Conclusions MELD-Na score not only acts as a parameter evaluating preoperative patients' conditions, but also serves as a pivotal parameter predicting postoperative incidence of AKI.
