Hepatitis B virus reactivation (HBV-R), which can lead to HBV-related morbidity and mortality, is a common and well-known complication that occurs during the treatment of non-Hodgkin lymphoma (NHL) patients with current or past exposure to HBV infection. HBV-R is thought to be closely associated with chemotherapeutic or immunosuppressive therapies. However, immunosuppressive agents such as anti-CD20 antibodies (e.g., rituximab and ofatumumab), glucocorticoids, and hematopoietic stem cell transplantation (HSCT) administered to NHL patients during treatment can cause deep immunodepression and place them at high risk of HBV-R. In this review, we explore the current evidence, the guidelines of several national and international organizations, and the recommendations of expert panels relating to the definition, risk factors, screening and monitoring strategies, whether to use prophylaxis or pre-emptive therapy, and the optimal antiviral agent and duration of antiviral therapy for HBV-R.
黏膜相关淋巴组织(mucosa-associated lymphoid tissue,MALT)淋巴瘤是一组低级别B细胞淋巴瘤,1983年由Isaacson和Wright首先提出[1].MALT淋巴瘤常表现为惰性临床过程,胃肠道是其最常见的发生部位.肺MALT淋巴瘤比较罕见,不到肺原发性恶性肿瘤的0.5%[2].由于肺MALT淋巴瘤发病率低,临床表现没有特征性,影像学不典型,极易漏诊、误诊.本文报道1例肺MALT淋巴瘤并复习相关文献,以提高对该病的认识.

Objective:To investigate the clinical characteristics of myelodysplastic syndromes (MDS) with autoimmune hemolysis as early manifestation and to discuss the early diagnosis of MDS.Methods:The clinical features,diagnosis and treatment of 1 case of MDS with autoimmune hemolysis as early manifestation were analyzed retrospectively.Results:The patient was characterized with autoimmune hemolyis early,and treated with enough glucocorticoid for one month,but there was no response.Reexamination of bone marrow cytology suggested morphologic dyshematopoiesis in erythroid.The patient transformed rapidly into acute myeloid leukemia after one month.Conclusion:MDS may present with pure hemolysis during early stage.Analysis of bone marrow cells of dysplastic hematopoiesis in the diagnosis of MDS is very important.CD41 immune staining can improve the efficiency of micromegakaryocyte detection,and help the early diagnosis of MDS.
Flow diverters, the specially designed low porosity stents, have been used to redirect blood flow from entering aneurysm, which induces flow stasis in aneurysm and promote thrombosis for repairing aneurysm. However, it is not clear how thrombus develops following flow-diversion treatment. Our objective was to develop a computation model for the prediction of stasis-induced thrombosis following flow-diversion treatment in cerebral aneurysms. We proposed a hypothesis to initiate coagulation following flow-diversion treatment. An experimental model was used by ligating rat’s right common carotid artery (RCCA) to create flow-stasis environment. Thrombus formed in RCCA as a result of flow stasis. The fibrin distributions in different sections along the axial length of RCCA were measured. The fibrin distribution predicted by our computational model displayed a trend of increase from the proximal neck to the distal tip, consistent with the experimental results on rats. The model was applied on a saccular aneurysm treated with flow diverter to investigate thrombus development following flow diversion. Thrombus was predicted to form inside the sac, and the aneurysm was occluded with only a small remnant neck remained. Our model can serve as a tool to evaluate flow-diversion treatment outcome and optimize the design of flow diverters.
Objective To discuss role of the rich sequence specific binding protein 1( special at rich sequence binding protein 1, SATB1)in initiating PI3K/Akt signaling pathway on the occurrence of thyroid cancer cells as well as invasion and metastasis. Methods The cul-tured thyroid cancer cells were divided into 4 groups:untreated group:in addition to DMEM without any treatment;LY294002 inhibited group:Cultured in DMEM with 10 μmol/L inhibitor LY294002;SATB1 inducer group:DMEM medium plus SATB1 antibody 200 μg/L;TSATB1 in-duced inhibition of group:DMEM medium plus SATB1L antibody 200μg/L and 10 μmol/L inhibitor LY294002. After 24 hours of culture acqui-sition cultivating base in thyroid carcinoma cells in serum by elase method to detect the expression of MMP9,IL-1 and IL-6 expression,on the cleavage of the thyroid cells using Western blotting were used to detect the expression of PI3K,Akt,p-Akt and PIP3,immunohistochemical de-tection cell SATB1 expression. Results The expression of SATB1 in different experimental groups was detected by immunohistochemical method. The expression of SATB1 was mainly in the cytoplasm of yellow,which was not expressed in cytoplasm. SATB1 expression was different in different treatment groups and the difference was statistically significant( P ﹤0. 05). The SATB1 induced agent histone SATB1 expression highest expres-sion of the lowest LY294002 inhibited group and the difference was statistically significant( P ﹤0. 05). Western blot results showed that different groups of PI3K,Akt,p-Akt and PIP3 expression was varied and the difference has statistical significance( P ﹤0. 05). The SATB1 induced a-gent group and the protein PI3K,Akt,p-Akt and PIP3 expression was the highest,the lowest was LY294002 inhibited group and the difference was statistically significant( P ﹤0. 05). Elase assays confirmed that different groups of MMP9,IL-1 and IL-6 expression was varied and the difference has statistical significance( P ﹤0. 05). SATB1 induced agent group and the protein PMMP9,IL-1 and IL-6 expression was the highest,the lowest was LY294002 inhibited group and the difference was statistically significant( P ﹤0. 05). Conclusion SATB1 is associated with invasion and metastasis of thyroid carcinoma;SATB1 has a role in the K PI3 / Akt signaling pathway,and SATB1 may be involved in the ex-pression of tumor microenvironment and inflammatory factors.

弥漫大 B 细胞淋巴瘤(DLBCL)是最常见的非霍奇金淋巴瘤(NHL),占成人 NHL 的30%~40%。尽管淋巴瘤的治疗已经有很大的进步,仍然有40%的 DLBCL患者死于疾病复发。随着对 DLBCL 临床、病理及分子病理研究的深入,新药物引入 DLBCL 的治疗,需要大样本的随机临床研究来评估新方案的疗效。目前国际预后指数(IPI,表1)已经不能满足临床预后评估。我们将近年来新的对临床及预后有重要影响的预后因素进行概述,以更好地指导临床治疗。
Objective To determine the effect of Wuzhi capsule (WZ) on pharmacokinetics of Tacrolimus (Tac) in kidney transplant patients who have taken WZ to reduce the dose of Tac for a long term.Method Twenty stable renal transplant patients with similar trough level of Tac were divided into WZ group (n =10) and control group (n =10).Whole blood concentrations of Tac at 0,0.5,1,1.5,2,3,4,6,8 and 12 h after the morning dose was determined.Estimated pharmacokinetic parameters were calculated and compared.Additionally,CYP3A5 genotypes of each patient were analyzed using Polymerase Chain Reaction Restriction Fragment Length Polymorphism to compare the effect of CPY3A5 genotypes and WZ on Tac dose requirement.Result Pharmacokinetics data showed that Co of Tac was 6.3μg/L in WZ group and 5.9 μg/L in control group.The average peak time of Tac was similar (1.4 h in WZ group,and 1.3 h in control group,P>0.05).Both the peak concentration of Tac and AUG0-12h of Tac were slightly higher in WZ group than in control group with the difference being not statistically significant.The frequency of CYP3A5 * 1/* 3 genotype was 60% in both groups,while the average dose of Tac was reduced by 30% in WZ group as compared with control group (0.042 mg·kg-1 ·day-1,and 0.067 mg·kg 1 ·day-1,P<0.01).In WZ group,the average dose of Tac was even lower in carriers of * 1/* 1 genotype (0.036 mg·kg-1 ·day 1) than that in carriers of * 1/* 3 genotype,which was close to the lowest dose requirement in the carriers of * 3/* 3 genotype from the control group (0.034 mg·kg-1 day-1).Conclusion In kidney transplant patients with CYP3A5 * 1 genotype,a long-term application of WZ to reduce the required tacrolimus dose is a generally safe way without significant changes in regular pharmacokinetics of tacrolimus.For patients with genotype of CYP3A5 * 1/* 1,WZ is particularly suitable.
Objective:To investigate the differences of MSI2and Numb expression in patients with leukemia or hematological non-malignant diseases,and explore its clinical significance.Method:Bone marrow samples of patiens with newly diagnosed acute leukemia or chronic myeloid leukemia in chronic phase patients were collected as the experimental groups,while bone marrow samples of healthy vonlunteers and patients with hematological non-malignant diseases were collected as a control group.Fluorescence quantitative PCR was performed to detect the expression of MSI2and Numb.Result:①The expression levels of MSI2in AML and ALL patients were significantly higher than those in CML patients and the control group.The differences between the ALL group and the latter two groups were statistically significant.However,the differences between AML group and the latter two groups were not statistically significant.②The expression levels of Numb in AML and ALL patiens were lower than those in CML patiens and normal controls.But those differences were not statistically significant.③There was no correlation between MSI2and Numb expression in patients with acute leukemia.④High expression of MSI2in ALL patients was positively correlated to the proportion of primitive cells.Conclusion:MSI2expression level is high in patient with acute leukemia,especially in those with ALL.Its expression level is associated with tumor burden.
Objective To recognize the characteristics of acute antibody-mediated rejection (AAMR) after kidney transplantation and to investigate the factors influecing the prognosis of AAMR after treatment.Method Three patients with negative cytotoxic cross-match developed early AAMR after kidney transplantation from Jan.2011 to Aug.2012.Pretransplant panel-reactive antibodies (PRA) were strong positive in 1 patient against class Ⅱ and negative in 2 patients who had positive PRA previously.All 3 patients had marked increase of PRA within 1 week post-transplantation and the renal allograft function deteriorated rapidly.After the diagnosis,plasmapheresis (PP)/intravenous immunoglobulin (IVIG) or combined with Bortezomib was used to treat AAMR.Result One patient underwent nephrectomy because of severe hemorrhage in the allograft at the time of diagnosis.One patient treated with PP/IVIG 4 times achieved a full recovery of renal function at postoperative day (POD) 50,while the rest failed to respond to PP/IVIG/Bortezomib treatments 5 times and the allograft had to be removed at POD 24 due to extensive hemorrhage and ischemic necrosis.Conclusion HLA sensitized patients are at high risk of AAMR after kidney transplantation,even with a negative pretransplant PRA.Immediate HLA antibody screening and allograft biopsy are needed to identify AAMR when the allograft represents non-function or early impaired function.PP/IVIG may be effective to treat AAMR,and the prognosis of AAMR depends on the time of when the treatment is started and the severity of antibody-mediated injury in the grafts.
由于移植肾功能的慢性减退,半数受者的移植肾存活时间不超过10年,因此近年来肾移植后恢复血液透析和等待再次移植的病例数明显增加.这些受者往往因前次移植而产生不同程度的致敏,其中高致敏者[群体反应性抗体(PRA)≥80%]不仅因广泛和高水平的抗HLA抗体而难以找到合适的供者,而且再次移植后更易发生排斥反应。
[Objective]To investigate differential gene expression in dendritic cell(DC) in response to human alloantigen and cytomegalovirus protein,and search target genes which can prevent graft rejection and eytomegalovirus (CMV) infection.[Methods]Genome-wide microarray analysis was performed to test gene expression in DC in response to human alloantigen and cytomegalovirus protein 3A(CMV3A).[Results]The Results showed that the difference of gene expression of DC induced by CMV3A and alloantigen was significant.The genes with differential expression included antigen processing and presentation,toll-like receptor signaling pathway and cell movement/migration, cytokine-cytokine receptor interaction and metabolism of xenobiotics by cytochrome p450,and several heat shock protein(HSP) family members including HSPA5,HSPA8,HSPA9B and HSP90AB1,in DC induced hy alloantigen were higher expression than that by CMV3A.[Conclusion]This study found several genes including heat shock protein family in DC induced by alloantigen were higher expression than that by CMV3A,these genes might play a valuable role in preventing graft rejection and CMV infection.

Background Negative pressure drainage has been shown to be an effective treatment of chyle fistula. However, the optimal level of negative pressure has not been determined. We therefore conducted a prospective randomized trial to address this issue. Methods In all, 21 patients with chyle fistula were randomly assigned to a high negative pressure suction (HNPS) group (-600 mmHg, n = 10) or low negative pressure suction (LNPS) group (-125 mmHg, n = 11). The duration of drain leakage and hospital stay, and the incidence of complications were compared between the 2 groups. Results All patients were successfully treated with conservative management without surgical intervention. The median durations of chyle leakage and hospital stay were significantly shorter in the HNPS group compared with the LNPS group: 4 versus 7 days (p = .0048) and 5 versus 11 days (p = .0107), respectively. Conclusions Negative suction was demonstrated to be highly effective in the management of chyle fistula, and HNPS appeared to be more efficient than LNPS. (c) 2011 Wiley Periodicals, Inc.
