Feasibility and safety of using low-body-weight donors in pediatric liver transplantation

BackgroundDonors with low-body-weight were previously reported to be related to inferior recipient outcomes in pediatric liver transplantation. However, the scarce availability of age and size-matched organs has encouraged us to re-evaluate the feasibility and safety of using low-body-weight donors.MethodsWe retrospectively analyzed 91 deceased donor pediatric liver transplantation between January 2014 and December 2016, donor weight less than 5 kg was defined as low-body-weight donors. The recipients were divided into two groups according to donor weight.(≤ 5 kg and 5 kg < to ≤ 20 kg). Donor and recipient characteristics, perioperative data, postoperative complications as well as graft and recipient survival rate were comparedResultsThe recipients and grafts recovery after transplantation were comparable between two groups. The recipients receiving low-body-weight donors showed higher risk of hepatic artery thrombosis and small-for-size syndrome, however, these complications can effectively be treated by our strategies. The 2-year patient survival rates were 92.9% and 95.2%, 2-year graft survival rates were 92.9% and 93.7% in Groups 1 and 2, without significant difference.ConclusionsOur finding suggested that the utility of livers from low-body-weight donors is a potential strategy to increase donor availability in well-selected pediatric recipients.Level of EvidenceIII     

基于相关可视化的壮骨关节丸特异质肝损伤与27种细胞因子的相关性分析

目的采用相关可视化的方法,探讨壮骨关节丸(Zhuangguguanjie Wan,ZGW)特异质肝损伤指标丙氨酸转氨酶(ALT)与27种细胞因子的相关性。方法 SD大鼠禁食12 h后,ig给予ZGW 3.8 g/kg,2 h后尾iv 2.8 mg/kg的脂多糖(LPS),给予LPS 10 h后水合氯醛麻醉大鼠,下腔静脉取血,采集肝组织样本。检测血清中ALT活力及肝脏组织27种细胞因子水平。R 3.2.4软件分析ALT与27种细胞因子及27种细胞因子之间的相关性。结果 ALT与巨噬细胞炎性蛋白1α(MIP-lα)和血管内皮生长因子(VEGF)之间具有较强的正相关性,白细胞介素-18(IL-18)、趋化因子-10(IP-10)、IL-1α和IL-1β之间具有很强的相关性,嗜酸性粒细胞趋化因子(eotaxin)或调节活化正常T细胞表达和分泌的趋化因子(RANTES)各自具有独立性。结论 ZGW特异质肝损伤与MIP-1α和VEGF之间具有较强的正相关性,为ZGW临床安全用药及风险防控提供新的实验证据。     

The prevalence of GB virus C/hepatitis G virus RNA among healthy and HCV-infected Catalan children

GB virus C (GBV-C) is a blood-borne flavivirus. The prevalence of GBV-C viremia among healthy adults is 0.5% to 4% and, to date, no disease has been definitely associated with GBV-C infection. We conducted a cross-sectional study to evaluate GBV-C viremia prevalence in a group of 327 healthy children with normal alanine amino transferase (ALT) levels (Group A) and elevated ALT levels (Group B) of unknown origin, and among 38 pediatric patients with mother-to-child-transmitted hepatitis C virus (HCV) infection (Group C). No statistically significant differences were observed between prevalences in Groups A and B (2.2% vs 6.7%, p = 0.06). None of the children in Groups A or B who tested positive for GBV-C RNA showed any clinical symptoms. The prevalence of GBV-C viremia in Group A was lower than for patients in Group C (2.2% vs 13.2%, p = 0.007); no differences were observed in HCV infection characteristics between those patients who were co-infected with GBV-C and those who were not. In conclusion, while GBV-C viremia is more frequent among HCV-infected pediatric patients, it is neither associated with liver disease nor has any influence on HCV-related chronic hepatitis.     

大学新生乙型肝炎病毒感染状况调查及分析

目的: 了解大学新生乙型肝炎(乙肝)病毒感染情况,为校园内乙肝的防治提供科学依据。方法: 采集蚌埠医学院2009级3 120名新生清晨空腹静脉血,分别采用酶联免疫法、改良赖氏法、重氮法测定乙肝表面抗原(HBsAg)、丙氨酸氨基转移酶(ALT)和总胆红素(TBIL)。结果: 3 120名新生中,HBsAg阳性99名,阳性率为3.17%;男、女生HBsAg阳性率分别为3.77%和2.82%,差异无统计学意义(P>0.05)。男、女生ALT异常率和TBIL异常率差异有统计学意义(P<0.01),ALT、TBIL异常者中男女生HBsAg阳性率差异无统计学意义(P>0.05)。结论: 新生HBsAg携带率比社会人群的HBsAg携带率低,对有HBsAg阳性的学生应加强管理,对易感人群进行乙肝疫苗接种,防止乙肝在学校传播。     

Predictors of hemorrhagic complications after intravenous thrombolysis in acute cerebral infarction patients: A single-center study of 391 cases

For patients with ischemic stroke, intravenous (IV) thrombolysis with Urokinase within 6 hours has been accepted as beneficial, but its application is limited by high risk of hemorrhagic complications after thrombolysis. This study aimed to analyze the risk factors of hemorrhagic complications after intravenous thrombolysis using Urokinase in acute cerebral infarction (ACI) patients.Total 391 consecutive ACI patients were enrolled and divided into 2 groups: the hemorrhagic complications group and the non-hemorrhagic complications group. The related data were collected and analyzed.Univariate analysis showed significant differences in prothrombin time, atrial fibrillation (AF), Mean platelet volume, large platelet ratio (L-PLR), triglyceride (TG), Lactate dehydrogenase, alanine aminotransferase (ALT), high-density lipoprotein, and baseline National Institute of Health Stroke Scale score between the hemorrhagic complications and the non-hemorrhagic complications group (P < .1). Multivariate logistic regression analysis indicated that AF (odds ratio [OR] = 2.91, 95% confidence interval [CI] = 1.06–7.99 P = .039) was the risk factor of hemorrhagic complications, while ALT (OR = 0.27, 95% CI = 0.10–0.72 P = .009) and TG (OR = 0.16, 95% CI = 0.06–0.45 P = .000) were protective factors of hemorrhagic complications.For patients with AF and lower levels of ALT or TG, the risk of hemorrhagic complications might increase after ACI.
