Objective To analyze the incidence and related risk factors of hyperuricemia after liver transplantation.Methods A total of 286 cases undergoing liver transplantation from 2009 to 2012 in the Armed Police General Hospital , who had normal uric acid before transplantation and had been followed up for more than 1 year, were enrolled in this study.The clinical data, including liver and kidney function , blood glucose, and lipids were collected .The potential risk factors of hyperuricemia were analyzed .Results 53.5% cases ( 153/286)had hyperuricemia after transplantation.Hyperuricemic patients were predominately older (P =0.038). They also had a higher prevalence of increasing creatinine (P=0.000),and hyperlipidemia(P=0.000).Among female cases, hyperuricemic patients had a higher average BMI (P=0.027).Hyperuricemia group had an elevat-ed ratio of blood lipids 60.1%(92/153), higher than normal uric acid group (39.1%,52/133) ( P<0.05). Conclusions Liver transplantation recipients have a higher incidence of hyperuricemia , particularly in elderly and overweight female patients .Our findings suggest that postoperative hyperuricemia may be associated with high serum creatinine, elevated blood lipids.We should strengthen follow-up, take early detection and early treat-ment.

Objective To wmpare the differences of the mixing time and contamination rate between liquid and powder EN preparations. Methods 20 patients,receiving enteral nutrition for more than 6 days, were enrolled in. this study. They were randomized to receive either powder enteral diet (control group, n=10) or liquid enteral diet (study group, n=10). The mixing time was examed by stopwatch. The contamination rate was determined by culture of bacteria in the solution. Results 1. The mixing time of study group was significantly shorter than that of control group ( 18.9 ± 3.0 vs 106.0 ± 21.0 , P<0. 001). 2. The bacterial culture in both groups were negative before enteral feeding. There was no positive case in study group and only 2 positive eases in control group after infusion. However, there was no statistical difference between the two groups ( P=0.14). Conclusions Liquid form of enteral nutfitent was less time cost and no ease contaminated by enveriorment, but it is expensive. he ligurd preparation has more advantages than powdor one in mixing time and comtamination.

Objective To investigate the effects of a newly developed health belief model (HBM)on the survival of liver transplant recipients. Methods The most important health concerns and follow-up service expectations were learned from out-patients who received long-term liver transplant follow up, and a new HBM for liver transplant was developed. The impact of the HBM on survival was evaluated in this prospective randomly controlled trial. Results In 374 liver transplant recipients who completed the questionnaire, the most common health concerns were the implication of follow-up service and optimal medications ,etc. Moreover,liver transplant club and improved role and function of health-care providers were expressed by the participants to enhance interactions with the medical staff. After 2 years' follow up, the incidence of abnormal liver function ( 16. 8% vs 21.2% ), infection ( 3.2% vs 10. 3% ) and disease recurrence (2. 6% vs 9. 8% ) were significantly decreased in the study group (n = 190) when compared with the control group ( n = 184) ( all P < O. 05 ). Conclusion Adverse health events could be reduced following the application of HBM for liver transplantation.

To summarize and explore the etiopathogenisis, clinical 'characteristics, diagnosis and treatment and prognosis of idiopathic adulthood ductopenia. We described a 27-year-old Chinese female initially manifested with jaundice, pruritus, dark urine, and pallor of the stools in October, 2002. Symptoms occurred repetitively and severed progressively, and she received therapy at the General Hospital of Chinese People's Armed Police Forces. B-ultrasound demonstrated that hepatic lesion and slightly swelling spleen. Pathological diagnosis of liver biopsy showed that she affected idiopathic adulthood ductopenia. The outcome of treatment of ursodeoxycholic acid and adrenal cortical hormone was not significant. She received orthotopic liver transplantation on June 24~(th), 2005. After liver transplantation, pruritus and jaundice were promptly disappeared. Each index of hepatic function recovered to a normal level. In March 2007, decreased dose of hormone induced an abnormal hepatic function, with mildly acute rejection. Drug dose was regulated, and hepatic function gradually returned to normal. During follow-up 51 months after the operation, she was doing well and was free of symptoms with normal liver function and no evidence of allograft dysfunction. The pathogenesis of idiopathic adulthood ductopenia is still unknown. There are still no precise and effective drugs for treatment of idiopathic adulthood ductopenia. Liver transplantation offers an effective therapy for end-stage patients with idiopathic adulthood ductopenia.

Objective To observe the effects of tacrolimus on blood glucose, insulin, expressions of protein phos-phatase 2A and P-AKT in rats in order to explore the mechanism of hyperglycemic action of tacrolimus. Methods Sixty male SD rats (body weight 89. 83 ±4. 44 g) were randomly divided into tacrolimus group (n =40) and control group (n=20). The rats in the tacrolimus group were administrated with tacrolimus 4 mg/kg daily. The rats in the control group were given the same amount of normal drinking water daily. The rat body weight, fasting blood glucose concentration and blood concentration of tacrolimus were measured monthly. All rats were killed at 5 months after the tacrolimus administra-tion. The serum insulin levels were detected by radioimmunoassay method. The expressions of PP2A and P-AKT in liver tissues were assessed by immunohistochemistry. Results After two months of administration, the blood glucose levels in the tacrolimus group were significantly higher than those in the control group. The HOMA-IR in tacrolimus group was signif- icantly higher than that in the control group P<0. 05 ) . ISI was significantly lower than that in the control group ( P<0. 05). Immunohistochemical examination showed that the expression of PP2A in hepatocytes in the tacrolimus group was increased compared with the control group, while expression of P-AKT in hepatocytes of the tacrolimus group was decreased than that in the control group. Conclusions Tacrolimus can induce necrosis of islet cells, decrease of the amount of islet cells and insulin secretion, decease of sensitivity to insulin, and increase the resistance to insulin, therefore, leading to in-crease the blood glucose level in rats. The expression of PP2A in hepatocytes in the tacrolimus group is increased, while the expression of P-AKT is decreased. Interfering of insulin signal transduction pathways may be involved in the hyperglyce-mic effects of tacrolimus.

Objective:
The aim of this study was to summarize and analyze the clinical features and characteristics of de novo HBV infection after liver transplantation in non-HBV-related liver disease.
Methods:
We retrospectively analyzed the clinical data of 13 patients with new HBV infection in 376 cases of liver transplantation patients with non-HBV related liver diseases from April 2002 to December 2013 in our hospital.
Results:
Among 376 patients with non-HBV-related liver disease after liver transplantation, 13 patients developed new HBV infection, and the rate of new HBV infection was 3.46%. Of the 13 cases, 5 were males and 8 were females. The follow-up time was 14.7 -128.7 months, and the average time from surgery to new HBV infection was 19.06 months. The primary diseases were as follows: 5 cases of primary biliary cholangitis, 3 cases of alcoholic liver disease, 2 cases of drug-induced liver damage, 1 cases of post-hepatitis C cirrhosis, congenital biliary atresia and congenital liver fibrosis. All patients were positive for HBsAg, HBeAg, anti-HBc, 11 were positive for HBV DNA, and 2 were negative for HBV DNA. 6 cases had abnormal liver function and 7 cases had normal liver function. All patients were treated with antiviral therapy with nucleoside (acid) analogues. HBsAg was negative in 6 patients; HBsAg remained positive in 7 cases, including HBsAg, HBeAg, anti-HBc positive in 6 cases, HBsAg, anti-HBe, anti- HBc was positive in 1 case, HBV DNA was still positive in 1 patient, and HBV DNA was negative in 6 patients; liver function was normal in all patients.
Conclusion
Non-HBV- related liver transplantation are high-risk group of new HBV infection, with the highest incidence of autoimmune liver disease. It is speculated that it may be related to the long-term use of hormones after the transplantation. The prognosis of newly diagnosed HBV infection after liver transplantation is fine as long as it can be found and treated early.
