The toxic effects of immunosuppressants are often dangerous factors which influence long-term survival of recipients.Individualized immunosuppressive therapy has been a hotspot and difficulty for comprehensive treatment of liver transplantation.Immunosuppressive therapy has been gradually developed to pursue long-term survival for receipients and graft,minimized side effects of immunosuppressants,optimized quality of life of patients,and reduce the economic burden of patients.Through consideration of patient's pathophysiological state,understanding the characteristics and side effects of various immunosuppressive,appropriate choose of the immune inhibitor,correct evaluation of immune state of recipients and graft,minimization of drug doses,individualized dosing regimen could be successfully carried out.

Liver hanging maneuver was firstly introduced by Belghiti et al in 2001,since then,the new technique has aroused widespread interest.The fatal weakness of liver hanging maneuver is bleeding resulting from blind dissection of the anterior plane of the inferior vena cava.In this review,the anatomic basis of retrohepatic tunnel and the surgical techniques were summarized to provide surgeons with suggestions in hepatectomy,liver transplantation or operations for hepatic trauma,so as to reduce the incidence of complications and raise the safety and success rate.

Objective To investigate the effect of donor specific immature dendritic cells infusion in combination with CsA on differentiation of liver recipient′s Th1/Th2 cell in rats. Methods Allograft models of orthotopic rat liver transplantation were established, 88 LEW rats (recipient) and SD rats (donor) were randomly divided into three groups: (1) in control group no immunosuppresive drug was used after liver transplantation. (2) in CsA group 1 mg/100 g body weight of CsA was injected intraperitoneally every the other day for 3 times beginning the 2nd day after liver transplantation. (3) in CsA+DC group additional 1? 10 6 immature DC from donor bone marrow was injected through penile vein at the 8th day after operation, in combination with CsA as in CsA group. Rats were sacrificed for immunopathological examination and detection of INF ?mRNA, IL 6 mRNA of celiac lymph node on 5th, 10th, 15th, and 25th day after transplantation. Results The average recipient survival time in the CsA+DC group was (27 0?1 0) days, significantly longer than that in control and CsA group (all P

A 13-year-old female patient with a mass in the right upper quadrant of the abdomen for 2 months were admitted to the Southwest Hospital on February 1,2009.She was first misdiagnosed as with congenital choledochal cyst,while further examination revealed that there was no relationship between the cyst and bile duct,so exploratory laparotomy was carried out.The cyst was located at the mesentery,and was confirmed as abdominal cyst developed from the oesophagus and ectopic gastric mucosa.

Objective To evaluate the diagnosis and treatment of primary breast lymphoma(PBL).Methods Clinical data of 49 PBL cases diagnosed in our center from 1997 to 2011 was retrospectively analyzed.Results 1 case was male,48 cases were female.Most patients were at the age of 35-55 years.Painless mass was the most common symptom which was most often seen on the upper-outer quadrant of the right breast,accounting for 61.11％ in this group.Preoperative misdiagnosis rate was high by mammography,B ultrasonic and hollow needle pathologic examination.Final diagnosis could only made by postoperative histopathologic examination.In this group 1 case was Hodgkin lymphoma and 48 cases were non-Hodgkin lymphoma(NHL) originating from B cells.46 patients underwent surgery and chemotherapy followed by radiotherapy in 16 cases.Median time of follow up was 40 months,5-year overall and disease free survival was 48％ and 28％ respectively,and bone marrow was the most common metastatic organ.Conclusions The prognosis of PBL is poor.The image diagnosis lacks specificity.Paraffin sections and immunohistochemistry were the main means to make a definite diagnosis.Chemotherapy-based comprehensive treatment is the strategy in the management of PBL instead of radical mastectomy.

Robotic surgery is a major trend of mini-invasive surgery,which is still in its infancy in China.The training and education of robotic surgeons is a problem to be solved imperatively.In our clinical practice,we explored the new strategy of training and education for hepatobiliary robotic surgeons by assimilating the essence of traditional surgery education and by drawing lessons from the successful training of robotic surgery in foreign countries.Satisfactory teaching effect was obtaincd.

Objective To assess the effects of orthotopic liver transplantation (OLT) on the quality of life (QoL) of the patients with end stage liver disease. Methods QoL of OLT recipients was assessed by the GLQI index of the digestive system disease. A total of 43 recipients with benign end stage liver disease without operational complications, who were clearly conscious and had no difficulty in comprehending the investigation table because of their relative good education above the middle school, had been investigated during May 2000 to December 2002. The detecting data were divided into three parts including before OLT, at discharge, and 3 months after discharge. Results At the stage of discharge, QoL of OLT recipients was improved as compared with that before OLT. The physical function, psychological status, symptom of the recipients had been significantly improved than as compared with those before OLT ( P 0.05). And at the stage of 3 months after discharge, QoL of the recipients was improved significantly than that in the hospital ( P

Objective　To study the effect of portal vein blocking on the permeability of the intestinal mucosa in pigs. Methods　Healthy Rongchang pigs were divided into 3 groups: ① sham operation group(SO), ② portal vein clamping for 45 min group (PVC-45'), ③ portal vein clamping for 60 min group (PVC-60'). Urine lactulose/mannitol(L/M) ratio was measured after portal vein blocking. Results　The L/M ratio was increased significantly (P<0.05) in PVC-45' and 60' groups than in SO group, with that of PVC-60' higher than that of PVC-45' group, but not significantly. Conclusion　The increase of intestinal mucosal permeability after portal vein blocking is an early and important index for the damage of the intestinal mucosa barrier.

Objective To evaluate the sensitivity and specificity of histopathologie analysis vs cytomegalovirus (CMV) detection for the diagnosis of CMV-infected hepatitis post liver transplantation. Methods Twenty-five biopsies with CMV infection and twenty-five without CMV infection were collected. Histopathologic observation, immunohistochemical staining and virus detection were performed on both groups to evaluate the sensitivity and specificity of these examinations for the diagnosis of CMV-infected hepatitis. Results The detection rate of microabscess, aggregation of monocyte and rnacrophage, and cytomegalic change in CMV infection group was higher than that in the group without CMV infection (P<0.05), but there was no significant difference in intranuclear inclusion and eosinophilic body between the two groups (P>0.05). The sensitivity and specificity of IHC and PCR for CMV detection were 20% and 100%, 72% and 84%, respectively. Conclosions CMV detection with PCR combined with histological observation is the most effective diagnostic scheme for CMV disease of liver.

Objective To summarize the strategies of treatment and investigate the risk factors affecting the survival of patients with hepatic cancer recurrence and metastasis after liver transplantation.Methods The clinical data of 99 patients with hepatic cancer recurrence and metastasis after liver transplantation who were admitted to the Southwest Hospital of Third Military Medical University from January 1999 to September 2011 were retrospectively analyzed.Of the 99 patients,7 patients who did not meet the criteria were excluded from the study,and 92 patients were enrolled in the study.All patients were divided into single therapy group (18 patients) and combined therapy group (74 patients).The study was reviewed by the ethics committee,and all the patients signed the informed consent form.The survival time of the 2 groups was compared,and the risk factors affecting the survival time was analyzed.All data were analyzed using the t test,chi-square test or by calculating the Fisher exact probability.The survival curve was drawn using the Kaplan-Meier method,and the survival time was compared by the Log-rank test.Factors influencing the prognosis were analyzed using the multivariate linear regression analysis.Results The survival time of patients in the single therapy group and the combined therapy group after hepatic cancer recurrence and metastasis were (5.5 ± 1.1) months and (8.5 ± 1.6) months,respectively,with a significant difference between the 2 groups (Log-rank value =7.489,P ＜ 0.05).The survival time were (7.9 ± 1.5) months for patients in TNM Ⅱ and Ⅲ A,and (7.0 ± 1.3) months for patients in TNM Ⅲ B and ⅣA,with significant difference between the 2 groups (Log-rank value =2.567,P ＜0.05).The survival time of patients with moderately or well differentiated tumors after tumor recurrence and metastasis was (8.1 ± 1.5) months,which was significantly longer than (7.2 ± 1.4)months of patients with poorly differentiated tumor (Log-rank value =2.749,P ＜ 0.05).TNM stage,tumor differentiation,Milan criteria,great vessel invasion were independent factors affecting the survival of patients with hepatic cancer recurrence and metastasis (t =2.610,3.132,4.378,2.258,P ＜ 0.05).Conclusions Combined therapy can significantly prolong the survival time of patients with hepatic cancer recurrence and metastasis.Earlier hepatic cancer recurrence and metastasis after liver transplantation result in a shorter survival time.TNM stage,tumor differentiation,great vessel invasion and Milan criteria are risk factors affecting the survival of patients with hepatic cancer recurrence and metastasis after liver transplantation.
