As a new kind of perioperative management strategy and ideas,enhanced recovery after surgery (ERAS) brings a series of traditional perioperative treatment measures for optimization based on evidence-based medicine.Its primary aim is to decrease surgery-related stress,complications,and also to facilitate recovery with multimodal treatments.The ERAS pathway has been widely applied and proved to be efficient in gastrointestinal,colorectal,orthopedic,thoracic and gynecological surgery.Owing to the complexity of surgical procedure,long operation time and high perioperative complication rate in liver transplantation compared with other surgeries.This new concept has not been widely accepted or recommended in liver transplantation,although some previous studies have validated its safety and effectiveness.This paper overviewed the recent literature on the specific procedures,efficacy,safety and development of ERAS applied in liver transplantation.

Objective:To investigate the influence of P27RF-Rho mRNA gene silencing in the drug sensitivity of 5-fluorouracil(5-Fu)to the liver cancer SMMC cell line,and to provide theoretical basis for the treatment of advanced liver cancer.Methods:The P27RF-Rho RNAi vector was constructed and the P27RF-Rho gene silencing lentivirus were used to infect the SMMC7721 cells.Western blotting method was used to detect the gene silencing effect.The SMMC7721 cells were divided into Scramble-siRNA group, 5-Fu group, P27RF-Rho siRNA group and P27RF-Rho siRNA + 5-Fu group.Western blotting was used to detect the transfection efficiency of RNAi.MTT method was used to detect the cell growth in various groups.Scratching test was used to detect the migration ability of cells in various groups.Transwell experiment were used to detect the invasion ability of cells in various groups.The expressions of P27 and RhoC protein were detected by Western blotting method.Results:P27RF-Rho RNAi lentiviral vector was successfully constructed.The Western blotting results showed that the expression of P27RF-Rho protein in P27RF-Rho siRNA group was decreased compared with 5-Fu group and Scramble-siRNA group(P<0.05).Compared with other three groups, the growth speed of the cells in P27RF-Rho siRNA + 5-Fu group was significantly decreased(P<0.05).The migration ability of the cells in P27RF-Rho siRNA + 5-Fu group was significantly lower than those in other three groups (P<0.01);the average number of cells passing through the Transwell microporous membrane was significantly less than those in other three groups (P<0.01).The Western blotting analysis results showed that the expression level of P27 protein in the cells in P27RF-Rho siRNA + 5-Fu group was significantly higher than those in other three groups(P<0.05);the expression level of RhoC protein was significantly lower than those in other three groups(P<0.05).Conclusion:P27RF-Rho gene silencing can significantly enhance the drug sensitivity of 5-Fu to SMMC7721 cells.

Objective To investigate the indications and clinical efficacy of combined application of laparoscope,choledochoscope and duodenoscope in the treatment of extrahepatic cholangiolithiasis.Methods The retrospective cohort study was adopted.The chnical data of 2 364 patients with extrahepatic cholangiolithiasis who were admitted to the First Hospital of Jilin University from January 2008 to December 2015 were collected.Of the 2 364 patients,861 patients had cholecystolithiasis combined with extrahepatic cholangiolithiasis and the diameter of common bile duct ≥ 8 mm,720 patients had cholecystolithiasis combine with extrahepatic cholangiolithiasis and the diameter of common bile duct ＜ 8 mm,783 patients had only extarhepatic cholangiolithiasis.In the patients diagnosed as cholecystolithiasis combined with extrahepatic changiolithiasis,laparoscopic cholecystectomy (LC) + laparoscopic common bile duct exploration (LCBDE) were applied to patients with the diameter of common bile duct≥8 mm,and the T-tube placement or primary suture was used intraoperatively according to the status of individualized patients;endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilation (EPBD) + LC were applied to patients with the diameter of common bile duct ＜ 8 mm.For patients with only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy,EST or EPBD was applied,and LCBDE was applied to patients with multiple stones and maximum diameter ＞ 2 cm and unsuitable for EST or EPBD.If residual stones were found after operation in patients with T-tube placement,choledochoscope was used to extract stone;otherwise,EST or EPBD was used.Treatment outcomes including treatment method,success rate of minimally invasive lithotomy,operation time,incidence of complication,duration of postoperative hospital stay and treatment expenses,and the results of follow-up including 1-,3-year recurrence rate of stones were recorded.The follow-up was done by outpatient examination and telephone interview till January 2016.All the patients were reexamined blood routine,liver function and color doppler ultrasonography of the abdomen at 1 month,3 months,6 months,1 year and 3 years after operation.Suspected residual cholangiolithiasis found by ultrasound was varified by computer tomography (CT) or magnetic resonanced cholangiopancreatography (MRCP) imaging examination.For patients with T-tube placement,CT scan and biliary photography were performed at 2-3 months postoperatively to determine whether residual stones existed and T tube could be pulled out.Measurement data were presented as mean (range).Results Of 2 364 patients,2 271 patients received minimally invasive lithotomy successfully.Of 861 patients of cholecystolithiasis combined with extrahepatic cholangiolithiasis and the diameter of common bile duct≥8 mm,836 succeeded in minimally invasive lithotomy,with a success rate of 97.10％ (836/861),the other 25 patients were converted to open surgery.Seven hundred and three patients of 836 patients received T-tube placement in LCBDE,and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 97 minutes (range,41-167 minutes),3.70％ (26/703),6.7 days (range,3.0-32.0 days) and 3.4 × 104 yuan (range,1.5 × 104-6.7 × 104 yuan),respectively.One hundred and thirtythree patients of 836 patients received primary suture,and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 89 minutes (range,39-123 minutes),3.01％ (4/133),4.1 days (range,2.0-17.0 days),2.1 × 104 yuan (range,1.6 × 104-3.4 × 104 yuan),respectively.Of 720 patients with the diameter of common bile duct ＜ 8 mm who underwent EST or EPBD + LC,687 succeeded in minimally invasive lithotomy,with a success rate of 95.42％ (687/720),the other 33 patients were converted to open surgery.The mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses of 687 patients were 101 minutes (range,69-163 minutes),2.91％ (20/687),5.6 days (range,2.0-15.0 days) and 2.8 × 104 yuan (range,2.0 × 104-6.4 × 104 yuan),respectively.In 783 patients with only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy,701 of 725 patients who were treated with EST or EPBD succeeded in minimally invasive lithotomy,with a success rate of 96.69％ (701/ 725),and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses of 701 patients were 47 minutes (range,11-79 minutes),2.28％ (16/701),3.7 days (range,2.0-19.0 days),1.7 × 104 yuan (range,1.3 × 104-5.5 × 104 yuan),respectively;47 of 58 patients who were treated with LCBDE succeeded in lithotomy,with a success rate of 81.03％ (47/58),and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 124 minutes (range,94-170 minutes),8.51％ (4/47),7.9 days (range,5.0-21.0 days) and 3.8 × 104 yuan (range,2.3 × 104-7.9 × 104 yuan),respectively.Of 2 364 patients,2 207 were followed up for a mean time of 38 months (range,1-72 months).The 1-,3-year recurrence rates were 2.74％ (19/693) and 5.08％ (24/472) in patients receiving LC + LCBDE,3.10％ (21/677) and 5.69％ (30/527)in patients receiving EST or EPBD +LC for cholecystolithiasis combined with extrahepatic cholangiolithiasis.The 1-,3-year recurrence rates were 3.22％ (20/621) and 6.11％ (25/409) in patients receiving EST or EPBD + LC,7.32％ (3/41) and 11.11％(2/18) in patients receiving LCBDE for only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy.Conclusions It is safe and effective to treat extrahepatic cholangiolithiasis based on combined application of laparoscope,choledochoscope and duodenoscope,with choosing appropriate indications as the key to improve the therapeutic effect.Primary suture in the LCBDE is recommended because it can protect patients from T-tube placement.

Objective To investigate the safety and clinical effect of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in the treatment of hepatocellular carcinoma (HCC) with cirrhosis.Methods The retrospective cohort study was adopted.The clinical data of 5 patients with primary HCC with cirrhosis who underwent ALPPS at the First Bethune Hospital of Jilin University between October 2014 and August 2015 were collected.The surgical plan was determined according to preoperative liver function and liver functional reserve.The patients underwent portal vein (PV) ligation and liver partition in the first staged surgery.The second staged surgery was performed when growing future live remnant (FLR) came up to the standard of safe section by rescan of computed tomography (CT) at 10,14,18 days after the first staged surgery,and hemihepatectomy and hepatic segmentectomy were applied to patients.(1) The intraoperative situations were observed,including the severity of liver cirrhosis,first staged surgery time,volume of intraoperative blood loss and FLR in the first staged surgery,interval time of surgery,growth rate of liver volume,ratio of FLR and standard liver volume (SLV),time and volume of intraoperative blood loss in the second staged surgery.(2) Pre-and postoperative biochemical indicators in the first and second staged surgeries were detected,including total bilirubin (TBil) and alanine phosphatase (ALT).(3) Postoperative situations were observed,including occurrence of complications,results of pathological examination and duration of hospital stay.(4) The follow-up using telephone reservation and outpatient examination was performed to detect tumors recurrence and metastasis and survival of patients by imaging examination and tumor marker test up to November 2015.Count data were represented as mean (range).Results (1) Intraoperative situations:of 5 patients,there were 1 patient with F3 of liver cirrhosis and 4 with F4 of liver cirrhosis.One patient was complicated with lots of peritoneal effusion,followed by acute renal failure,and didn't receive the second staged surgery.Four patients underwent successful ALPPS.The first staged surgery of 5 patients:average operation time,volume of intraoperative blood loss,FLR,interval time of surgery,growth rate of liver volume,ratio of FLR and SLV were 282 minutes (range,240-320 minutes),500 mL (range,300-700 mL),457 em3(range,338-697 cm3),15 days (range,14-18 days),58％ (range,46％-67％) and 42％ (range,32％-44％),respectively.Average operation time and volume of intraoperative blood loss in second staged surgery were 220 minutes (range,200-260 minutes) and 412 mL (range,300-600 mL).(2) Pre-and post-operative biochemical indicators:levels of TBil and ALT of 5 patients from pre-operation to postoperative day 12 in the first staged surgery were from 4.9-30.4 μmol/L to 9.8-56.1 μmol/L and from 12.9-156.1 U/L to 46.3-207.3 U/L,respectively.Levels of TBil and ALT of 4 patients from pre-operation to postoperative day 10 in the second staged surgery were from 10.1-21.2μmol/L to 6.9-38.0 μmol/L and from 30.8-55.5 U/L to 19.8-72.8 U/L,respectively.(3) Postoperative situations:there were no perioperative death and postoperative complications of liver failure and intraperitoneal infection.One patient complicated with bile leakage was cured by non-operative treatment for 30 days.Results of pathological examination:5 patients were confirmed as Ⅱ-Ⅲ stage HCC,and 4 tumors had vascular tumor thrombi and negative resection margin with tumor size of 8-13 cm.Duration of hospital stay of 5 patients was 36 days (range,28-48 days).(4) Results of follow-up:4 patients undergoing successful ALPPS were followed up for 4-12 months.One patient was emerged with a new lesion of 2 cm in left half liver at postoperative month 7,level of AFP of which was 512 μg/L before the first staged surgery reduced to normal level at postoperative month 2,and then the patient received transcatheter arterial chemoembolization (TACE) and radio frequency ablation (RFA) treatments without tumor recurrence up to postoperative month 12.No tumor recurrence and new lesions in liver were detected in other 3 patients by abdominal enhanced scan of CT,with a normal level of AFP.Conclusion ALPPS is safe and feasible for HCC with cirrhosis,with a satisfactory short-term outcome.

Objective:To investigate the silencing of P27RF-Rho gene with lenvirus targeting mediated technique,and to clarify its influence in the invasion of liver cancer cells.Methods:The P27RF-Rho RNAi lentivirus was constructed. The liver cancer BEL7402 cells were infected with lentivirus. The experiment was divided into P27RF Rho-siRNA group, scramble-siRNA group and BEL7402 group.The effect of silencing P27RF-Rho gene and the expression levels of hepatocellular carcinoma (HCC)associated proteins RhoA,RhoC, VEGF,P53 and PTEN were detected;the activities of matrix metalloproteinase (MMPs)associated with tumor invasion were analyzed by Gelatin zymography;the variation of transfer ability and invasion abilities were compared by Wound healing assay experiment and Transwell experiment.Results:The Western blotting results showed the expression levels of P27RF-Rho,RhoA,RhoC,and VEGF proteins in the BEL7402 cells in experiment group were significantly lower than those in two control groups (P<0.05),and the expression levels of P53 and PTEN were higher than those in two control groups (P<0.05).The results of Gelatin zymography showed the activities of MMPs in experiment group were significantly lower than those in two control groups (P<0.01 );Wound healing assay showed that the migration ability of the BEL7402 cells in experiment group was significantly inhibited (P<0.01);the number of cells passed through the Transwell Chambers in experiment group was significantly less than those in two control groups (P<0.01).Conclusion:Silenceing P27RF-Rho can weaken the invasion ability and migration ability of human HCC BEL7402 cells.

Objective A successful salvage treatment of acute graft-versus-host disease (GVHD) after liver transplantation(OLT) with prognosis of immune tolerance was reported and the treatment experience was summed up.Methods A 46-year-old man with hepatic carcinoma recurrence after resection underwent OLT from an ABO-identical male donor after cardiac death due to brain death.Post-transplant immunosuppression regimens consisted of induction with anti-interleukin-2 receptor monoclonal antibody (basiliximab) followed by maintenance with tacrolimus,mycophenolate mofetil and low dose of steroids.On the postoperative day (POD) 20,the patient developed skin rashes on his limbs and trunk,and skin biopsy showed histological features consistent with acute GHVD.Donor-recipient dominant HLA was matched at 6 loci,with donor CD3 + T-cell chimerism positive Results Immunosuppressants were withdrawn.Basilixirnab combined with high dose of steroids was used,and the dosage was quickly reduced.Anti-irnfection treatment was strengthened.The skin rash recovered quickly,while the hemogram was significantly decreased,which was insensitive to colony stimulating factor.The fever came back with the skin rash on the POD 46.The modified hormone regimen was used,low dose of steroids with slowly reduction,and the patient recovered with the normal hepatic function.Conclsion With the untypical clinical presentation,pathological examination,HLA-matching and chimerisms,aGVHD could be early detected and diagnosed,with a therapy of low dose of steroids with slow reduction combined with basiliximab.Recipient achieved immune tolerance,which may result from the high match of HLA and chimerisms.

ObjectiveTo investigate postoperative application of multidisciplinary treatment (MDT) in hepatobiliary and pancreatic malignancies based on the pathological results. MethodsThe clinical data of patients who were diagnosed as hepatobiliary and pancreatic malignancies who were diagnosed and treated with postoperative MDT in our hospital from Apirl 2014 to March 2015 were analyzed. MDT was performed by consultation for four to six patients once every other week. The postoperative comprehensive treatment strategy for each patient was discussed and determined by all experts in the consultation. The effect of postoperative treatment and prognosis was summarized . Results25 postoperative MDT consultations on hepatobiliary and pancreatic malignancies were held for 131 patients, including 53 patients with hepatocellular carcinoma, 7 patients with intrahepatic cholangiocarcinoma, one patient with mixed-type liver cancer, 3 patients with metastatic liver cancer, 2 patients with liver sarcoma, 29 patients with extrahepatic cholangiocarcinoma, 22 patients with pancreatic cancer, 5 patients with gallbladder cancer, and 9 patients with periampullary cancer. After surgery, 38 patients received interventional treatment, 19 systemic chemotherapy, 15 radiotherapy, 17 cell biotherapy, and 5 molecularly targeted therapy. The case fatality rate was 2.29%（3/131）. ConclusionPostoperative MDT provides scientific and rational personalized comprehensive treatment for patients with hepatobiliary and pancreatic malignancies, and improves medication compliance in patients, which holds promise for wide application.

Cholestatic liver disease is a common disease in infancy,and due to its complex etiology and different outcomes,conservative medical treatment and conventional surgery lack therapeutic effect.Liver transplantation has obvious advantages in the treatment of decompensated intrahepatic cholestatic liver disease and biliary atresia.This article summarizes the etiology,clinical manifestations,diagnosis,and treatment of infantile cholestatic liver disease,as well as related perspectives.

Objective To investigate the role of multi-disciplinary team (MDT) in the treatment of complex cholestatic liver injury after liver transplantation. Methods MDT consultation was conducted to clarify the causes and therapeutic strategies for one case of complex cholestatic liver injury after liver transplantation admitted to Liver Transplantation Center of the First Hospital of Jilin University on June 23, 2020. And the role of MDT in the treatment of complex cholestatic liver injury after liver transplantation was summarized. Results The patient presented with abnormal liver function after liver transplantation. The diagnosis of biliary stricture, rejection and biliary tract infection was confirmed successively. Endoscopic retrograde cholangiopancreatography (ERCP) stent internal and external double drainage, glucocorticoid shock and anti-infection therapy yielded low clinical efficacy. After MDT consultation, complex cholestatic liver injury after liver transplantation was confirmed. It was suggested to optimize the immunosuppressive regimen based on the exclusion of rejections by pathological examination, deliver targeted anti-infection interventions and prevent the potential risk of concomitant drug-induced liver injury. The patient was discharged after proper recovery. Conclusions The causes of complex cholestatic liver injury after liver transplantation are diverse, and the condition changes dynamically. MDT consultation are performed to deepen the understanding of this disease, strengthen the classification of diagnosis and treatment ideas and enhance the precision and efficacy of corresponding treatment.
