BACKGROUND: It is an important subject that how to relieve liver injury during perfusion preservation, and the pretreatment for donated liver is considered to be an effective method in this process, however, most studies are limited in animal experiment. Atomolan is a kind of reduced glutathione, which possess bidirection regulation of metabolism and detoxication. OBJECTIVE: To study the protective effect of reduced glutathione Atomolan on donor liver injury.METHODS: Totally 80 patients received liver transplantation in the Liver Transplantation Center, 81 Hospital of Chinese PLA, from May 2003 to August 2006, were divided into the control (n = 42), and Atomolan (n = 38) groups. The perfusion preservation conditions were similar, except 2.4 g glutathione was added into solutions in later group. Adenosine triphosphate (ATP) and malonaldehyde levels in liver tissues were measured, meanwhile, the liver tissues were observed under a light microscope and an electron microscope. Recipient plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin concentrations were assessed at 1 day post-operation.RESULTS AND CONCLUSION: Compared with the control group, the liver ATP level of the Atomolan group was markedly increased (P < 0.01), MDA was decreased (P < 0.01), and the concentrations of ALT, AST, as well as total bilirubin were notably decreased (P < 0.01). Under a light microscope, it showed that the degrees of liver swelling histopathologic hepatic alterations were significantly lessened in the Atomolan group. While under an electron microscope, the structure of liver cells of the Atomolan group was clearer and included a higher number of mitochondria (P < 0.01). Results suggested that reduced glutathione has protective effect on donor liver injury during the procedure of hot and cold ischemia and perfusion.

BACKGROUND: Early enteral nutrition (EEN) following liver transplantation can benefit to recover and guarantee the normal gastrointestinal tract function,which plays an important role on post-operational immunosuppressive therapy.OBJECTIVE: To conduct EEN on the patients undergoing liver transplantation,and observe the post-operation recovery of intestinal function.DESIGN: Case analysis.SETTING: The 81 Hospital of Chinese PLA.PARTICIPANTS: From April 2003 to June 2006,86 patients undergoing liver transplantation in Liver Transplantation Center at the 81 Hospital of Chinese PLA were enrolled,including 57 males and 29 females.They aged 21-68 years,with a mean of 48 years.Among them,there were 37 cases of primary hepatic carcinoma and 49 cases of posthepatitic cirrhosis; 8 cases graded in Child A (all hepatic carcinoma),34 cases in Child B,and 44 cases in Child C.And 5 cases were complicated with serious hepatitis liver function failure and hepatic coma.Informed consents were obtained from all the patients and relatives.Transplantation operation was approved by the hospital ethical committee.METHODS: Surgical approach was orthotopic liver transplantation through caval vein in 80 cases,typical orthotopie liver wansplantation without veno-venous bypass in 4 cases,and piggyback orthotopic liver transplantation in 2 cases.The average warm ischemia time was (4.8±2.4) minutes,and average cold ischemia time was (8.6±3.2) hours.Anhepatic phase was (84±28)minutes.Post-operational trigeminy immunity and anti-rejection therapy consisted of tacrolimus (Fujisawa product) +mycophenolate mofetil (Roche product) + prednisone (Pred).According to the presence of nasogastric feeding tube,the patients were divided into control group (n=49) and EEN group (n =37).There were no significant differences in the sex,age and general data of patients between the two groups.Control group adopted EEN mainly,while EEN group was fed with EEN via a nose-intestine nutritional tube,and they received short-peptide enteral nutrition (Pepti-2000) at 24 hours post-operation at the initial dose of 63-126 g/d,which was gradually increased to 372 g/d.Liquid diet was allowable by 3-5 days.MAIN OUTCOME MEASURES: ①Clinical recovery and complications of patients.②Liver function recovery indices such as total serum protein,albumin and prealbumin,as well as C reactive protein at days 1,3,5 post-operation.③Level of serum immune globulin at day 7 post-operation.RESULTS: Totally 86 patients were involved in the result analysis.①Clinical recovery and complications: In EEN group,abdominal distension occurred in 10 cases,diarrhea in 5 cases,and blocking or slippage of feeding tube in 3 cases; No emesia,back flow or aspirated pneumonia was found; In control group,2 cases appeared bile leakage,which was not detected in the EEN group.②Indices of liver function recovery: Compared with control group,the prealbumin level was significantly rised and C reactive protein was significantly decreased in the EEN group at days 3 and 5 (P ＜ 0.05).③Levels of serum immune globulin: Blood IgA and IgM of EEN group were significantly higher than those of control group at day 7 (P ＜ 0.05).CONCLUSION: EEN in post-operation patients can reduce stress,promote synthesize metabolism,improve the recovery of liver cells,and decrease the infection rate.

Objective: To preliminarily investigate the relationship between the baseline level of serum soluble ST2 (sST2) and 30-day MACE occurrence rate in patients with ST-elevation myocardial infarction (STEMI).
Methods: A total of 121 patients with confirmed diagnosis of STEMI in our hospital from 2015-05-01 to 2015-07-30 were consecutively enrolled. According to baseline sST2 level, the patients were divided into 2 groups:Low sST2 group, the patients with sST2≤56.68 ng/ml, n=61 and High sST2 group, the patients with sST2>56.68 ng/ml, n=60. Clinical condition and 30-day MACE (defined as death and new onset of congestive heart failure) occurrence rate were compared between 2 groups.
Results: ① The systolic blood pressure (SBP), Killip class≥II grade, blood levels of cTNI, NT-proBNP, hs-CRP and LVEF were different between 2 groups, all P<0.05. ② Baseline sST2 level was positively related to heart rate (r=0.271, P=0.003), Hs-CRP (r=0.359, P=0.000), cTNI (r=0.324, P=0.000) and NT-proBNP (r=0.425, P=0.000);negatively related to SBP (r=-0.226, P=0.013) and LVEF (r=-0.406, P=0.000).③30-day MACE occurrence rate was different between 2 groups (8.2%vs 30%, P=0.002). ④ Multivariate Cox regression analysis presented that sST2>56.68 ng/ml was the risk factor for 30-day MACE occurrence (HR=1.152, 95%CI 1.078-1.231, P=0.000).
Conclusion: Increased baseline level of sST2 implied the higher incidence of death and new onset of congestive heart failure in STEMI patients.
