ABSTRACT

Objective To investigate the effects of adoptive reinfusion of regulatory T cell (Treg) on the recovery of islet function and graft survival time after islet allograft transplantation. Methods The diabetic model was established using C57BL/6 mice as recipients, and Balb/c mice were chosen as donors for islet allografts transplantation beneath the renal capsule. The recipient mice were divided into 3 groups and 3 mice in each group according to different processing Methods: Treg experiment group (Treg group, 1×106 Treg cells were injected via tail vein at 1 d before operation), positive control group [sirolimus (SRL) group, SRL at a dose of 300 μg/(kg·d) was intragastrically given every day from 1 d before operation] and blank control group (control group, an equivalent volume of normal saline was intragastrically given every day from 1 d before operation). Enzyme-linked immune absorbent assay (ELISA) was used to detect the changes of blood glucose and C-peptide in mice within 14 days after transplantation. In vivo imaging technique was used to dynamically monitor the survival of mice within 14 days after transplantation. Results In each group, the blood glucose levels at postoperative 3 d were significantly decreased compared with those before transplantation (all P < 0.001). At postoperative 1 d, the C-peptide levels showed an explosive rise to varying degree in each group. At postoperative 3 d, the C-peptide levels in each group were significantly higher than that before operation (all P < 0.001). At the end of the observation period at 14 d after operation, the C-peptide levels in the SRL and Treg groups were (427±50) pmol/L and (833±57) pmol/L, relatively higher than that in the control group. But the blood glucose levels were (14.5±0.5) mmol/L and (12.1±0.6) mmol/L, significantly lower than that in the control group (all P < 0.001). Compared with the SRL group, the explosive release amount of C-peptide was significantly lower, the declining trend was more remarkably stable, and the C-peptide level was considerably higher in the Treg group at the end of the observation period (all P < 0.001). At postoperative 14 d, the grafts were almost completely apoptotic in the control group, over 50% of the grafts survived in the SRL group, and over 80% of the grafts survived in the Treg group. Conclusions Adoptive reinfusion of Treg cells can effectively protect islet grafts, prolong the survival time of grafts, and maintain the normal levels of blood glucose and C-peptide in the recipient mice.

ABSTRACT

Objective To summarize our experience in the diagnosis and treatment of hepatic epithelioid angiomyolipoma (HEAML),with the aim to reduce the future misdiagnosis rate.Methods The PubMed,Medline,China Science Periodical Database (CSPD),and VIP Databases were searched from January 2000 to March 2018 on all reports on HEAML.Results There were 409 cases of HEAML in 97 reports.The ratio of men to women was 1∶4.84.The age ranged from 12 to 80 years and the median age was 44 years.61.9% of patients (205/331) were asymptomatic,while 34.7% (115/331) had upper or right upper quadrant abdominal discomfort.Some patients presented with abdominal mass,gastrointestinal reaction,low grade fever or weight loss.The clinical symptoms in 78 patients were not mentioned in the reports.The misdiagnostic rate of HEAML was as high as 40.3% (165/409).The imaging findings of HEAML were nonspecific.Ultrasound,CT and MRI scan usually showed contrast enhancement in the arterial phase.Most lesions were accompanied by central vessels with early drainage veins.The enhanced scans showed varied characteristics.The ratios of fast wash-in and fast wash-out,to fast wash-in and slow wash-out,and to delayed enhancement were roughly 4∶ 5∶ 1.A definitive diagnosis of HEAML is based on the pathological findings of epithelioid cells in the lesions and the expressions of HMB45,SMA,Melan-A and Actin on immunohistochemical staining.HEAML had a relatively low malignant rate of 3.9%.Surgical resection was the main treatment for HEAML.Conclusion HEAML was a rare and easily misdiagnosed disease.,which could be diagnosed by taking into account the clinical course,imaging,pathological and immunohistochemical findings.HEAML.

ABSTRACT

The understanding of anatomical structures and their adjacent relationship is the founda-tion and key to the development of surgical skills and clinical thinking. In clinical teaching for residents and graduate students , we took the advantage of donor operations in organ transplantation and showed abdominal anal operations anatomical features and relationships through different view angles and compre-hensive ways. This new teaching approach was designed in accordance with processes of organ donation, procurement and back-table operation. The main contents included anatomy of abdominal wall layers, rela-tionships among abdominal organs, locations and courses of important structure, as well as medical human-istic education. In the context of organ donation becoming more and more popular and standardized after the cardiac death of Chinese citizens, this teaching approach is worth exploring.

ABSTRACT

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.

ABSTRACT

Objective To investigate the protective effect of a COX inhibitor,flurbiprofen (Flurb) on hepatic ischemia/reperfusion (IR) injury in rats and the action mechanism.Method C57BL/6 mice were randomized into sham,IR and Flurb (4 different doses) groups.The model of segmental (70%) warm hepatic ischemia was established in IR and Flurb groups.Flurbiprofen of different doses (5,7.5,10 and 15 mg/kg) was injected via the tail vein 20 min before ischemia.At different time points after reperfusion,liver cell necrosis and apoptosis were evaluated by HE and TUNEL staining.The COX and inflammatory cytokine gene expression was detected by using realtime PCR.Liver mitochondria were separated and mitochondrial permeability transition (MPT) pore sensitivity was examined by using swelling assay and fluorescence spectrophotometry assay.Result In flurbiprofen groups of different doses,the serum AST and ALT levels were significantly decreased at 6 h after reperfusion as compared with IR group.Moreover,10 mg/kg Flurb pretreatment significantly inhibited the mitochondrial permeability transition (MPT) pore opening,and thus alleviated liver cell damage and prevented mitochondria-related cell death and apoptosis by inhibiting COX-2 and inflammatory factor genes expression such as IL-1β,IL-6 and TNF-α.Conclusion Flurbiprofen protects mice from hepatic I/R injury possibly by inhibiting mitochondrial permeability transition and IL-1β,IL-6 and TNF-α expression,which may provide experimental evidence for clinical use of flurbiprofen to protect liver function in surgical settings other than its conventional use for pain relief.

ABSTRACT

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.

ABSTRACT

Objective To summarize the clinical experience in liver retransplantation. Methods The clinical data of 24 patients receiving liver retransplantation 28 times in this hospital were retrospectively analyzed and discussed with relevant literature. Results Among the 880 consecutive liver transplantations, 28(3.18%) had liver retransplantation. The causes of liver retransplantation were biliary complications ( 16 cases, 57. 1%), carcinoma recurrece (6 cases, 21. 4%), hepatic artery thrombosis (4 cases, 14. 3%), chronic rejection (1 case, 3. 6%), primary nonfunction (1 case, 3.6%). Thirteen patients among the 24 were discharged healthy and were followed up for 51days to 67months. Eleven patients died. Three of them died of hemorrhagic shock, 2 of septic shock, 2 of hepatocellular carcinoma recurrence, 2 of cardiovascular system complication, 1of nervous system complication, and 1 of hepatic artery thrombosis. Conclusion Liver retransplantation can effectively save patients with graft failure. Proper indication, optimal operating time, improvement of operative skills,and appropriate treatment during the perioperative period are very important for promoting the rate of successful liver retransplantation.

ABSTRACT

Objective To investigate the surgical options for the management of portal vein thrombosis (PVT) during liver transplantation and its impact on the outcome of patients. Methods 773 cases of liver transplantation were analyzed retrospectively. PVT occurred in 107 patients, inclu-ding 59 of grade Ⅰ ,33 of grade Ⅱ, 12 of grade Ⅲ and 3 of grade Ⅳ. Simple thrombectomy or thrombus-extraction was performed in grade Ⅰ and Ⅱ. 12 patients with grade Ⅲ received thrombus-extraction or using the donor iliac vein to act as a bridge between the donor portal vein and host superior mesenteric vein. Two cases of grade Ⅳ received a modified cavo-portal hemitransposition and one case received portal-vena coronaria varication anastomosis. Results Liver function had a good recover and the perio-perative mortality is 4. 3% in grade Ⅰ and Ⅱ. In grade Ⅲ , 5 cases received thrombus-extraction had a normal liver function after transplantation and had no died. 2 cases among the other 7 cases using por-tal vein reconstruction had bad liver function and died. The liver function recovered well after trans-plantation and there was no died in grade Ⅳ. Conclusions PVT is not a contraindication for liver transplantation. Good results can be obtained by applying reasonable operative procedures individually.

ABSTRACT

Objective To investigate some improvements in the surgical techniques of adult-to-adult living donor liver transplantation( A-A LDLT) without the middle hepatic vein(MHV) for hepat-ic vein reconstruction. Methods The retrospective analysis was made on the clinical data of 11 recipi-ents who underwent the operation in A-A LDLT including the hepatic vein reconstructed in right liver lobe without MHV from June 2007 to January 2008. The key techniques included reconstructing out-flow of graft on shaping the tips of vena cava and right hepatic veins, cadaveric vein allografts stored in 4℃ UW solution within 7d being used for significant-sized hepatic vein reconstruction such as tributa-ries of the middle hepatic vein from V5, V8 and right inferior hepatic vein. Results 10 cases success-fully underwent reconstruction of outflow of graft on shaping the tips of vena cava and right hepatic veins and the outflow reconstruction ratio of V5, V8 and right inferior hepatic vein was 81. 8% (9/11), 7 one-vein reconstruction, 1 two-vein reconstruction and 1 three-vein reconstruction. 1 recipient died of renal failure and pulmonary infection 14 days after operation without venous outflow obstruc-tion. Doppler ultrasonography showed no thrombosis and the blood flowed smoothly in the right he-patic vein of other 8 recipients during the 9th to 15th mouth of follow-up. The cumulative patency rates of these 8 survivals for interposition vein grafts were 100% (11/11), 72. 7 %(8/11), 54. 5%(6/11) and 36. 5%(4/11) in 1, 3, 6 and 9 mouths, respectively. The regeneration of paramedian sectors was equivalent. Conclusion Shaping the tips of vena cava and right hepatic veins and using cadaveric vein allografts in adult-to-adult right lobe living donor liver transplantation for hepatic vein reconstruc-tion are both safe,simple and effective methods.This approach can be recommended.

ABSTRACT

Objective To evaluate the protective effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) in mice. Methods Thirty C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, I/R group (mice were injected with 5 ml/kg saline by tail vein just before ischemia induction) and hydrogen-rich saline group (mice were injected with 5 ml/kg hydrogen-rich saline). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The Scr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. Malondialdehyde (MDA) contents in renal samples were measured using specific kits. The infiltration of F4/80 positive macrophages and neutrophils was assayed by using immunohistochemistry. The mRNA expression of TNF-α, IL-6, IL-1β and IL-17 was detected by using real time reverse transcription PCR. Results As compared with LR group, at the 6th h following reperfusion the levels of Scr and BUN were significantly reduced (P<0.05), histological changes obviously alleviated (P<0.01), apoptosis of renal tubular epithelial cells and MDA contents was decreased (P<0.05) in hydrogen-rich saline group. Moreover, the infiltration of macrophages and neutrophils, and the mRNA expression of TNF-α, IL-6, IL-1β and IL-17 in renal tissue in hydrogen-rich saline group were also declined as compared with IR group (P<0.05). Conclusion Hydrogen-rich saline can ameliorate renal IR injury to some extent, which is associated with inhibition of inflammatory response induced by reperfusion.

ABSTRACT

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.

ABSTRACT

Objective To study the effects of Sinomenine on the dendritic cells after hepatic ischemia-reperfusion. Methods Forty-eight BN rats were equally divided into control group, low dose (40 μg/g) and high dose (80 μg/g) of Sinomenine groups after the liver transplantation models were established by two cuff tech-nique. Three days after the orthotopic liver transplantation, the livers were resected, then the dendritic cells were separated and purified. The phenotypes [OX62, major histocompatibility complex Ⅱ (MHC-Ⅱ) and CD86] of dendritic cells were examined by FACS, the expression of IL-12, IL-1, and TNF-a mRNA by RT-PCR, and the expression of Toll-like receptor 4 (TLR4) by Western blot. Results The dendritic cells treated with Sinomenine showed immature phenotypes. The expressions of MHC-Ⅱ and CD86 were significantly deceased. The expressions of IL-12, IL-1, TNF-a mRNA and TLR4 were low. Conclusions Sinomenine can significantly inhibit the maturity and immunologic function of dendritic cells after hepatic ischemia-reperfusion.
