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.

Objective:To explore the relationship between gene mutation in the pre-C region of hepatitis B virus (HBV) and acute-on-chronic liver failure (ACLF) associated with hepatitis B.Methods:Fifty-eight patients with chronic hepatitis B (CHB) admitted to the General Hospital of Northern Theater Command of the Chinese People′s Liberation Army from May 2020 to May 2023 were selected as the CHB group, 51 patients with chronic hepatitis B liver cirrhosis (CHB-LC) were selected as the CHB-LC group, and 52 patients with hepatitis B-related acute-on-chronic liver failure were selected as the ACLF group. The clinicopathological data of the three groups were collected for retrospective analysis. Peripheral serum HBV DNA of the three groups was collected. The pre-C region genes of HBV in the three groups were amplified by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and then gene sequencing was performed. The variation at position 1896 of the pre-C region gene of HBV in the three groups was recorded. The general data, hepatitis B e antigen (HBeAg), HBV DNA quantification, triglycerides (TG), total cholesterol (TC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), and gene mutation in the pre-C region of the three groups were observed and compared. Logistic regression analysis was performed on the related influencing factors of the onset of hepatitis B-related ACLF.Results:There were no statistically significant differences in gender, age, disease course, body mass index (BMI), TG, TC, and BUN among the three groups (all P>0.05), and there were statistically significant differences in HBeAg, HBV DNA quantification, ALT, and AST among the three groups (all P<0.05). The HBV DNA quantification, ALT, and AST in the ACLF group were higher than those in the CHB group and the CHB-LC group (all P<0.05). The mutation rate at position 1896 of the pre-C region gene of HBV in the ACLF group was higher than that in the CHB group and the CHB-LC group (all P<0.05); The results of logistic multivariate regression analysis showed that HBV DNA quantification, ALT, and gene mutation in the pre-C region were independent influencing factors for the onset of hepatitis B-related ACLF ( OR=1.042, 1.570, 1.413, P<0.05). Conclusions:The variation at position 1896 of the pre-C region gene of HBV is common in patients with HBV infection at different disease courses. The incidence of its variation shows a gradually increasing trend in CHB, CHB-LC, and ACLF. Elevated HBV DNA and ALT and gene mutation in the pre-C region of HBV are independent risk factors for the occurrence of hepatitis B-related ACLF. The progress of the disease in such patients requires clinical attention.

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 evaluate the effects of pegylated interferon (Peg-IFN) alfa-2b combined with nucleotide analogues (NAs) on the recurrence of hepatitis B-related liver cancer after resection, and to explore the changes of HBsAg and HBV DNA in patients with chronic hepatitis B liver cancer during postoperative treatment.Methods:The prospective study was conducted. Clinical data of 43 patients with hepatitis B-related liver cancer who underwent radical resection treated in 900th Hospital of People′s Liberation Army were prospectively analyzed from January 2020 to December 2021. Among 43 patients, there were 39 males and 4 females, the age was 30-76 years. According to different treatment methods they were divided into two groups, the patients treated by Peg-IFN alfa-2b combined with NAs were devided into the IFN group( n=10), and those treated by NAs alone into the NAs group( n=33). Two-pair semi-quantitative were collected every 3 months after operation. The recurrence-free survival rate, recurrence time after 2 years in the two groups, the clearance rate and the negative rate of HBsAg and HBV DNA in the two groups. Peg-IFN alfa-2b was evaluated in improving the prognosis of hepatitis B-related liver cancer. The measurement data of normal distribution were expressed by mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Chi-square test was used for comparison between the two groups of count data. Repeated analysis of measurement variance was used for analysis HBsAg and HBV DNA changes of the interferon group overall survival time and recurrence-free surrival time of patients was estimated using Kaplan-Meier method and the difference between groups was assessed using Log-rank test. Results:HBsAg and HBV DNA: The HBsAg clearance rate at 24 weeks and that at 48 weeks in the IFN group were 24.6% and 59.0% respectively. The HBsAg negative rate at 48 weeks was 16.7%. The HBV DNA clearance rate at 24 weeks and that at 48 weeks were 33.9% and 53.8% respectively. The HBV DNA negative rate was 0 at 48 weeks. The levels of HBsAg and HBV DNA in the IFN group decreased gradually with time. There were statistically differences between the levels of HBsAg and HBV DNA at 0 weeks, 24 weeks and 48 weeks( P<0.05). The 2-year overall survival rates of IFN group and NAs group were 100% and 90.9% respectively. The 2-year recurrence-free survival rates were 90.0% and 63.6% respectively. There were no significant statistical differences in the overall survival rate and recurrence-free survival rate between the groups ( P>0.05). The postoperative recurrence time of the IFN group and the NAs group were (15.00±7.07) months and (5.78±3.39) months respectively. The difference between the two groups was statistically significant ( t=3.160, P<0.01). Conclusion:Long-term antiviral therapy of Peg-IFN alfa-2b combined with NAs can prolong the recurrence time of liver cancer, reduce the levels of HBsAg and HBV DNA in serum, and potentially improve the survival rate of the patients compared with therapy of NAs alone.

Objective To investigate the correlation of serum irisin level with insulin resistance and left ventricular remodeling after PCI in patients with ST-segment elevation myocardial infarction(STEMI)without diabetes.Methods A total of 485 STEMI patients without diabetes who received emergency PCI in our hospital from January 2017 to August 2020 were recruited in this study.According to the quartile values of baseline serum irisin levels,they were divided into low(＜0.31 mg/L,n=161),medium(0.31-0.97 mg/L,n=150),and high irisin groups(＞0.97 mg/L,n=174).Serum irisin level was measured with ELISA and insulin resistance was assessed by homeostasis model.During a follow-up of 12 months,the relationship between serum irisin level and echocardiographic parameters was evaluated.Results Compared with the baseline irisin level,the level reached a peak of at 8 h after PCI,and decreased a minimum at 3 d after surgery,with statistical differences(P＜0.01).The low irisin group had significantly higher BMI,diastolic blood pressure,fasting blood glucose,fasting insulin,TG,cTnI peak and NT-proBNP levels,but youn-ger age when compared with the medium irisin group and the high irisin group(P＜0.05).Obvi-ously higher diastolic blood pressure,fasting insulin,TG,cTnI peak and NT-proBNP levels were observed in the medium irisin group than the high irisin group(P＜0.05).Pearson correlation analysis showed that baseline serum irisin level was negatively correlated with HOMR-IR,ΔLVEDD,ΔLVESD,ΔLVEDVi and ΔLVESVi(r=-0.338,r=-0.172,r=-0.164,r=-0.154,r=-0.167,P＜0.01).Multiple linear regression analysis indicated that after further ad-justment for impaired glucose tolerance and BMI,low irisin level was still independently associat-ed with ΔLVEDD(P＜0.01).Conclusion Baseline irisin level in STEMI patients without diabetes is correlated with insulin resistance and subsequent poor left ventricular remodeling,and is expec-ted to be a predictor of left ventricular remodeling after PCI.

Severe acute pancreatitis is one of the most common surgical emergencies with rapid onset, rapid progression, multiple complications, poor prognosis, and high morbidity and mortality, and it still faces many challenges in treatment. Surgical interventions are crucial in many complications of SAP mainly infected pancreatic necrosis in the late course of the disease, and there is a basic consensus on delayed intervention and trauma ascending treatment model, but over-emphasis on delay may cause patients to miss the best treatment period, and following a single treatment model may delay the patient′s condition. Therefore, it is of great significance for surgeons to grasp the correct indications and timing of surgical intervention and to develop appropriate surgical intervention strategies to reduce the morbidity and mortality of severe acute pancreatitis and improve the clinical prognosis of patients. In this paper, we review the progress of surgical treatment of severe acute pancreatitis with domestic and international literature.

Hilar cholangiocarcinoma(HCCA) is a hotpot and a difficult point in the field of hepatobiliary surgery. HCCA is the most common type of cholangiocarcinoma and is characterized by atypical early clinical manifestations, rapid progression and poor prognosis. There is no specific marker for HCCA and its preoperative diagnosis and evaluation mainly relies on imaging examination. Surgical treatment is still the main treatment, but most patients have lost the opportunity of surgical resection by the time of treatment. In recent years, a large number of studies have been conducted on the diagnosis and treatment of HCCA at home and abroad, and the efficacy of HCCA has been improved. Perioperative management, including the selection of preoperative drainage and perioperative chemoradiotherapy and others, improved postoperative survival. Among them, the application of preoperative radiotherapy and chemotherapy in the field of liver transplantation has achieved quite good results. Targeted therapy and immunotherapy have provided new treatment methods for HCCA. This paper reviews the diagnosis and multimodal treatment of HCCA.

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.

Three patients received surgical treatment in Department of Hepatobiliary Surgery of Mengchao Hepatobiliary Hospital from December 2020 to February 2022. Ceftriaxone sodium was given prophylactically before and after operation,and gallbladder silt stones were found by imaging examination on the 3rd, 3rd and 2nd after surgery in 3 patients, respectively. No special treatment was given,after the withdrawal of ceftriaxone sodium for 28, 38 and 48 d,radiographic examination showed that calculi disappeared spontaneously. It is suggested that the pseudolithiasis may be related to administration of ceftriaxone sodium.

Objective:To investigate the application value of three-dimensional (3D) visualization combined with indocyanine green (ICG) fluorescence imaging in anatomical hepatectomy for hepatocellular carcinoma (HCC).Methods:Clinical data of 45 patients with HCC who underwent anatomical hepatectomy in the Department of Hepatobiliary Surgery, the 900th Hospital of Joint Logistic Support Force of People′s Liberation Army from September 2019 to December 2020 were retrospectively analyzed. Among them, 27 patients were males and 18 were females, aged from 28 to 73 years, aged (57.76±10.95) years on average. According to the different surgical methods, all patients were randomly divided into ICG group ( n=24) and control group ( n=21). In ICG group, 15 patients were males and 9 females, aged (58.21±11.81) years on average. Anatomical hepatectomy was performed using 3D visualization combined with ICG fluorescence imaging. In control group, 12 patients were male and 9 female, aged (57.24±11.35) years on average. Conventional anatomical hepatectomy was performed. The operation duration, bleeding volume, the numbers of cases underwent blood transfusion, occlusion durations, days of hospitalization, highest postoperative serum ALT and TBiL, duration of recovery of postoperative serum ALT and TBiL, and incidence of complications were observed. Measurement data with approximately normal distribution were represented by ( Mean± SD) and groups were compared using t test. Measurement data with skewed or uneven distribution were represented by M (rang) and groups were compared using Man-Whitney U test. Count date were compared using Fisher exact test. Results:All the patients underwent successful operations, without perioperative death. In ICG group, the operation duration was 110.50 (44.00-145.00) min and the occlusion durations was (15.17±2.14) min respectively, shorter than 122.00(80.00-255.00) min and (17.29±4.35) min in control group, the difference between the two groups were statistically significant ( Z=-2.002, -2.115; P<0.05). In ICG group, the numbers of cases underwent blood transfusion was 2 cases, less than 8 cases in control group, the difference between the two groups was statistically significant ( χ2=4.147, P<0.05). The bleeding volume, days of hospitalization, highest postoperative serum ALT and TBiL, duration of recovery of postoperative serum ALT and TBiL, postoperative complications between the two groups were not statistically different ( P>0.05). Conclusions:3D visualization combined with indocyanine green fluorescence imaging technique is a feasible surgical method for anatomical hepatectomy. It is helpful for liver surgeons to visualize and recognize the boundary between hepatic segments and improve the safety of anatomic hepatectomy.
