Objective To investigate the effect of augmenter of 1iver regeneration(ALR)on hepatocytes transplanted intraperitoneally in acute hepatic failure(AHF)rats.Methods AHF SD rats were induced by D-gal.The rats were divided into 5 groups randomly:blank control group(only receiving normal saline),transplantation control group(transplanting 2 X 107 hepatocytes from SD rats),ciclosporin A group(CsA group,receiving hepatocytes and CsA 6 days after transplantation),ALRgroup(receiving hepatocytes plus ALR 6 days after transplantation),ALR control group(only receiving ALR 6 days after transplantation).All drugs and cells were intraperitoneally injected.There was a observation period of 14 days after transplantation.The survival rate of receptors and transplanted hepatocytes was observed.The expression levels of CD4,CD8 and CD68 in abdominal cells,the levels of IL-1β and TNF-a in serum and douche of peritoneal cavity were detected.Results The 2-week SuFvival rate in blank control group,transplantation control group,CsA group,ALR group and ALR control group was 0,46.7%,20%,66.7%and 14.3%respectively.Survival rate in AI.R group was higher than in blank control group(P=0.001).Serum levels of d1-2 TNF-a in ALR group was all lower than in blank and transplantation control groups(P＜(0.01).Serum levels of d1-2 IL-18 in ALR group were lower than in transplantation control group.Ascitic levels of d1-2 TNF-a and IL-1β in transplantation control group were higher than in other groups(P＜0.05,P＜0.01).The serum levels of TNF-a and IL-1β in all survival groups were similar tO normal levels on the 14th day after transplantation.The positive expression rate of d1-2 CD68 in grafts of ALR group was(0.5±0.3)%.The positive expression rate of CD68 in grafts of ALR group was obviously lower than in transplantation control group and CsA groups(P＜0.01).The expression of d1-2 CD68,CD4 and CD8 in ALR group was respectively(1.3±1.2)%,(0.1±0.3)%and(0.2±0.1)%,all obviously lower than in transplantation control group(P＜0.01,P＜0.01,P＜0.05).Assembled conglobate hepatocyte noduses were observed in abdominal cavity in rats receiving hepatocytes transplantation during first to third day after transplantation.The number of survival grafts in ALR group was more than that in transplantation control group and CsA group,and infihrated inflammatory cells were less.On the 14th day posttransplantation.small amounts of normal hepatocytes in grafts were observed only in ALR group.Conclusion After HcT plus ALR intraperitoneally,the survival rate of AHF rats was increased.ALR improved survivorship of transplanted hepatocytes in short term.

Objective:To investigate the inhibiting and apoptosis-effects inducing of the recombinant Ganoderma Lucidum immunoregulatory protein(rLZ-8) on HL60 cells.Methods:HL60 cells were cultured and the inhibited rate of HL60 cells was measured by means of MTT assay.Apoptosis rate was detected with annexinV/PI.The Calcium ion level was analyzed by Fluo-3/AM stain.Caspase-3 activity was assessed by caspase-3 colorimetric assay.Results:The experiments indicated that rLZ-8 could induce the HL60 cells apoptosis.The calcium ion level was increased and caspase-3 activity elevated in HL60 cells after treated by rLZ-8.Conclusion:rLZ-8 could inhibit the proliferation and induce apoptosis of HL60 cells efficiently.The mechanism may be related to increased calcium ion level and elevation of caspase-3 activity.

Objective To investigate the relation between lesions of medullary infarction and clinical symptoms and signs.Methods Eleven patients with medullary infarction confirmed by MRI were identified.Their clinical presentations and the relation between clinical presentation and location of lesion in MRI were assessed and analyzed.Results Among the 11 patients,5 cases suffered from lateral medullary infarction,6 medial medullary infarction(including two cases of bilateral infarction).Regarding clinical symptoms,common symptoms in lateral medullary infarction are blurred speech,dizziness,choking water,swallowing difficulties and facial numbness;in medial medullary infarction are limb weakness and blurred speech.The common signs of lateral medullary infarction are dysarthria,sensory disturbance,Horner sign and facial paralysis;in medial medullary infarction are paralysis of limbs and peripheral paralysis of the tongue.Conclusion Clinical manifestations are vailed depending on the sites of medullary infarction.MRI is helpful in diagnosing of medullary infarction.

Ocular adnexal lymphoma is a common orbital malignant tumor.The incidence of ocular adnexal lymphoma is in-creasing rapidly each year,and the clinical manifestations and imaging characteristics of the disease are not specific.Therefore,the diagnosis of the disease relies on pathological tissue analysis.Accurate diagnosis of ocular adnexal lymphoma relies on mor-phology,immunohistochemistry,molecular and cytogenetics.With in-depth research on the disease,it has been found that the clinical prognosis of this tumor is characterized by high recurrence.This article mainly explains the correlation between high dis-ease recurrence rate and histopathological characteristics.

Objective To investigate the effect of extracorporeal membrane oxygenation (ECMO) on critical patients with non-pulmonary primary disease in the emergency department. Methods The literature of English and Chinese clinical studies on the ECMO treating critical patients with non-pulmonary primary disease published before August 2017 were electronically searched on PubMed, Embase and other databases. The obtained articles were selected, their qualities were strictly evaluated, and the in-hospital survival rate, 3-month, 6-month and 1-year survival rate, as well as the average intensive care unit (ICU) and length of hospital stay were extracted. This meta-analysis were performed using RevMan software (Version 5.0, Cochrane collaboration). Results A total of 11 articles (n=3043) were enrolled including 616 cases of ECMO treatment group and 2427 cases of control group. Fitting results showed that compared with the traditional treatment, application of ECMO can improve the in-hospital survival rate[52.1％(321/616) vs. 32.1％ (780/2427); OR=2.02; 95％CI:1.11-3.67, P=0.02] and the survival rate more than 90 days[42.1％ (61/145) vs. 17.1％ (38/222); OR=3.98; 95％CI:2.30-6.89, P<0.01];and prolong the average length of hospital stay (MD=-5.35, 95％CI:-8.10--2.60, P<0.01) and ICU time(MD=-8.99, 95％CI:-8.20--1.80, P<0.01). Conclusions Meta-analysis of existing studies showed that application of ECMO can improve the short-term and long-term prognosis of critical patients with non-pulmonary primary disease. However, due to the small number of studies and the large heterogeneity of the study population, it is necessary to carry out more, large samples and high quality randomized controlled clinical trials.
