ObjectiveTo study chronic inflammatory demyelinating polyneuropathy(CIDP)after allogeneic hematopoietic stem cell transplantation(allo-HSCT)and the clinical manifestation,diagnosis and treatment.MethodsThe clinical manifestation,laboratory examination,treatment and outcome of a patient with chronic myeloid leukemia after allo-HSCT were studied.ResultsAcute and chronic graft-versus-host disease(GVHD) were occurred in the patient followed by chronic multiple nervous system symptoms from +105 day including facioplegia,decreased muscle strength and dysuria.According to clinical manifestation,results of cerebrospinal fluid exam and electroneurophysiology exam,CIDP was diagnosed.The clinical condition was improved after treatment with intravenous immunoglobulin,glucocorticoid, immunosuppressive agents and functional exercises,but the patient died of secondary infection finally.ConclusionCIDP after allo-HSCT is a rare complication of nervous system and difficult to diagnose and treat.Numerous transplant-related causes are probably associated with the development of CIDP.The main causes are GVHD and immune dysfunction.Early accurate diagnosis and rational treatment is of great importance.

OBJECTIVE:To investigate the effects of quercetin on human lung cancer NCI-H1395 cell apoptosis. METHODS:CCK-8 was used to detect the effects of 0-200 μmol/L quercetin on human lung cancer NCI-H1395 cell proliferation after treated for 12,24 and 48 h. Hochest33258 staining and flow cytometry were used to detect the effects of 0,20,50,100 μmol/L quercetin on NCI-H1395 cell apoptosis after treated for 24 h. The effects of 100 μmol/L quercetin on NCI-H1395 cell apoptosis was investi-gated after treated with Caspase-8,Caspase-9,Caspase-3 inhibitor. RESULTS:Quercetin could inhibit NCI-H1395 cell prolifera-tion in dose and time-dependent manner. 20,50,100 μmol/L quercetin could induce the apoptosis of NCI-H1395 cell,and apoptot-ic rates were (18.6 ± 4.1)%,(39.1 ± 4.5)% and (58.2 ± 3.5)%. Caspase-8 and Caspase-3 activation inhibition could obviously weaken the inhibitory effects of quercetin on cell(P<0.05). CONCLUSIONS:Quercetin can inhibit NCI-H1395 cell proliferation and induce cell apoptosis,which is related to the external way of cell apoptosis through activating Caspase-8 and Caspase-3.

Objective:To investigate prognostic factors of the T-cell non-Hodgkin’s lymphoma (T-NHL),and to study the clinical efficacy of CHOPE plus L-asparaginase (L-ASP)regimen for T-NHL.Methods:Retrospective analyses were made of 61 T-NHL patients who were treated from July 2007 to August 2013.Randomly divided into two groups CHOPE and CHOPE +L group (Based on CHOPE,added with L-ASP on the 1st,3rd,5th,7th,9th and 11th day).Results:Of the 61 patients evaluatd with the median survival was 22 (3 -65)months,the complete remission rate was 52.50%,the partial remission rate 29.51%,and the response rate 80.01%.The complete remission rate was 57.89%,and the patial remission rate 84.21% in CHOPE +L and the complete remission rate 43.48%,the response rate 78.26% in CHOPE,respectively (both P >0.05).The 1-,2-,and 5-year overall survival rates were 91.0%,87.6% and 65.7% respectively (P >0.05 ).But the overall survival rate in CHOPE +L was significantly higher than that in CHOPE group in extranodal NK/T-cell lymphoma,nasal type (ENKTCL)(P <0.05 ).The analysis of the prognostic factors indicated that ENKTCL,the outside junction lesions,and the CR rate were poor factors with statistic significance in T-NHL.Conclusion:CHOPE +L regimen has better efficacy for ENKTCL,but whether CHOPE +L regimen is used in the treatment of T-NHL,large prospective clinical trials are worth for further investigation.

Objective To evaluate the survival status and efficacy,prognosis and safety of several combined chemotherapies in previously untreated patients with follicular lymphoma (FL).Methods Clinical data of 62 previously untreated FL patients were analyzed retrospectively,in order to analyse survival status and to compare the efficacy and safety of different combined chemotherapies.Results The percent of FL patients achieved complete response (CR) after initial therapy was 80.0 ％ (44/55),while achieved for more than 5 years accounted for 23.6 ％ (13/55).Ten-year overall survival (OS) rate was 77.8 ％.The relapse rate was 34.5 ％,and the OS rate in patients with recurrence was significantly lower than in non-recurrence patients (93.8 ％ vs 61.6 ％,P =0.012).The disease-free survival (DFS) and progression-free survival (PFS)rates in FC/FMD (fludarabine,cyclophosphamide/fludarabine,mitoxantrone,dexamethasone) group comparing with CHOP (cyclophosphamide,epirubicin,vincristine,prednisone)-like group were significantly higher (80.0 ％ vs 21.1％ and 80.0 ％ vs 29.2 ％,P ＜ 0.05),but the differences had no statistical significance when adding rituximab (88.9 ％ vs 72.7 ％ and 90.0 ％ vs 73.5 ％,P ＞ 0.05).The OS,DFS and PFS rates in rituximab group were higher than those in the group without it (96.4 ％,79.2 ％ and 79.2 ％ vs 82.9 ％,39.3 ％ and 44.5 ％,P ＜ 0.05).The DFS and PFS rates in fludarabine group comparing with the group without it were significantly higher (86.2 ％ vs 49.4 ％,87.1％ vs 52.7 ％,P ＜ 0.05),but the differences between OS rates had no statistical significance (92.9 ％ vs 89.1％,P ＞ 0.05).The major adverse effects were hematologic toxicity,infection,nausea/vomiting and abnormal liver function.The hematologic toxicity of chemotherapies including fludarabine was stronger,but well-tolerated.Conclusion With initial combined chemotherapies,the CR rate of FL could receive a higher level.It is considered that chemotherapy might cure a part of FL patients thoroughly.Rituximab could increase the OS time significantly.FC/FMD regimen could increase the PFS time,comparing with CHOP-like regimen,while the difference has no statistical significance when adding rituximab.Systemic chemotherapies are well tolerated.

Diabetic rats were induced by intraperitoneal injection of streptozotocin.TUNEL and immunohistochemistry results showed that the renal tubular cell apoptosis index(AI)and Bax protein expression were significantly reduced,and the Bcl-2 protein expression in glomeruli was significantly increased in diabetic rats with stable hyperglycemia treated by benazepril compared with diabetic rats with stable hyperglycemia treated by vehicle(all P

Objective:To search for differences in early immune reconstitution after allogenic or autolo-gous hematopoietic stem cell transplantation (HSCT).Methods:The peripheral blood (PB)from 31 adult patients undergoing allogenic HSCT (allo-HSCT,1 5 patients)or autologous HSCT (auto-HSCT, 1 6 patients)for the treatment of hematological malignancies and from 20 related healthy controls (HC) from December 201 1 to August 201 4 was used to analyze the kinetic recovery of lymphocyte subsets by means of flow cytometry during 1 2 months after HSCT.The T cell receptor rearrangement excision circle (TREC)levels among CD3 + T cells were measured in the patients and HC to evaluate the thymic-dependent T cell reconstitution.Results:The allo-and auto-HSCT recipients did not differ significantly in CD4 + T cells,CD8 na?ve T cells,effecter memory T cells (TEM),CD4 central memory T cells (TCM),mid-activated T cells and dendritic cells (DC)during the follow-up (P >0.05).But they both differed significantly from HC (P <0.05).CD8 + T cells and NK cells reconstructed rapidly.There was no significant difference in the numbers of B cells between the allo-and auto-HSCT groups from M1 to M3 (P >0.05).B cells in both the groups were lower than those in HC (P <0.05).The recovery of B cells in auto-HSCT group was faster than in allo-HSCT group at M6 and M1 2 (P <0.05).The frequen-cies of CD4 na?ve T cells and later activated T cells in allo-HSCT group were significantly higher than in auto-HSCT group at M6 and M1 2 (P <0.05).The frequencies of CD8 TCM in auto-HSCT group were significantly higher than in allo-HSCT group at M6 and M1 2 (P <0.05).The TREC levels were signifi-cantly lower than in both the groups compared with the age-matched HC during the follow-up (P <0.05).No significant difference was observed between allo-HSCT and auto-HSCT groups (P >0.05). Conclusion:The differences of the nature and the speed of lymphocyte reconstitution observed between the two patents groups were minor.This leads us to conclude that in allografted patients,immune recons-titution and subpopulations of peripheral blood lymphocytes are probably not related to the allogenicity of the graft,but due to the impaired thymus functions and slow differentiation of T lymphocytes in thymus.

Objective To evaluate the application of inguinal incision in retroperitoneal laparoscopic nephroureterectomy(LNU)in the treatment of upper urinary urothelial carcinoma(UUUC).Methods From Mar.2007 to Jan.2012,186 retroperitoneal LNU procedures on 115 males and 71 females for the treatment of UUUC were performed in our institute.All cases were grouped as inguinal incision group(n =112)and lumbar incision group(n =74)according to specimen retrieval incision.Operative time,estimated blood loss,postoperative analgesia,hospital stay,incision complications,cosmetic satisfaction and tumor recurrence were compared between the 2 groups.Results All the 186 cases of operation were successfully accomplished.There were no differences in tumor stage,tumor grade,mean operative time,blood loss between the 2 groups.In inguinal incision group,the incidence of incision fat liquefaction,incision hernia,incision bulging,lumboabdominal unsymmetry and postoperative analgesia was less than that of lumbar incision group.In inguinal incision group,the mean hospital stay was shorter,cosmetic satisfaction(Ⅰ/Ⅱ/Ⅲ)was better(7/24/81 versus 22/18/34,P ＜ 0.01).Recurrence rate of UUUC in middle and inferior segment of ureter was fewer than that of lumbar incision group(5.3％ versus 35.0％,P ＜0.01).Conclusion Retroperitoneal LNU for UUUC combined with inguinal incision offers advantage of less trauma,less complications,higher cosmetic satisfaction and lower tumor recurrence.

Objective To investigate the related factors of relapsed refractory Hodgkin lymphoma (HL),analysis treatment and adverse reactions.Methods Clinical features and treatment outcome of 62 HL patients were analyzed retrospectively.Results Of the 62 HL patients,12 patients(19.35 ％) were relapsed refractory HL.Pathologic type (P =0.026),lymph node area ≥ 3 (P =0.030) and large mass (P =0.006) were important factors for relapsed and refractory.The median overall survival time of relapsed refractory HL was 69.5 months (27-129 months).The 5 year overall survival (OS) rates in relapsed refractory HL and others were 66.7 ％ and 88.8 ％ respectively (P =0.117).The 5 year event-free survival (EFS) rates in relapsed refractory HL were 52.4 ％ and others 87.9 ％ respectively (P =0.006).Conclusion Pathologic type,lymph node area ≥3 and large mass are closely related with refractory refractory.HL.At the same time,recurrence in the short-term (＜ 1 year) is the independent prognostic factor for patients with relapsed refractory HL.

Objective To evaluate the fludarabine instead of cyclophosphamide in modified busulfancyclophosphamide (mBuCy) regimen as a new myeloablative conditioning regimen for the treatment of acute leukemia patients receiving allogeneic hematopoietic stem cell transplantation (HSCT).Methods The clinic data of 45 acute leukemia patients undergoing allogeneic HSCT were analyzed.Among them,23 patients received mBuCy as conditioning regimen and 22 patients received BuFlu regimen (fludarabine 40 mg·m-2·d-1 for 5 days,instead of cyclophosphamide in mBuCy).Hematopietic engraftment,regimen-related toxicity (RRT),graft-versus-host disease (GVHD),infection condition,non relapse mortality,and overall survival were compared between the two groups.Results All patients achieved hematopoietic reconstitution and complete donor chimerism except for one patient of mBuCy group died of cerebral hemorrhage during conditioning.The incidence of RRT was no significant differences (P ＞ 0.05).In BuFlu group,the incidence of virus infection was higher (P =0.009),and the incidence of Ⅲll-Ⅳ aGVHD were 26.l ％ (6/23) and 4.5 ％ (1/22) (P =0.046) in mBuCy and in BuFlu group respectively.With a median follow up of 41 months,the incidence of non relapse mortality in mBuCy group was 17.4 ％ (4/23) and in BuFlu group was 9.1％ (2/22) (P =0.665).In mBuCy group and in BuFlu group,the relapse rates were 30.3 ％ (7/23) and 40.9 ％ (9/22) (P =0.474),the 5-year overall survival rates were (55.1±11.9) ％ and (61.4±10.8) ％ (P =0.659),and disease-free survival rates were (44.5±12.1) ％ and (22.1±12.3) ％ (P =0.747),respectively.Conclusions Fludarabine instead of cyclophosphamide in mBuCy regimen as a new myeloablative conditioning regimen has well tolerance,lower incidence of sever GVHD,satisfied overall survival,but the risk of infection and replase should be considered.

Objective To quantitatively analyze the early warning value of laboratory indexes for death risk in children with criti ‐cal hand foot and mouth disease (HFMD) .Methods The univariate and multivariate Logistic regression analysis were conducted to explore the independent risk factors of death in critical HFMD children .Then the area under receiver operating characteristic curve (AUC) was applied to give the comprehensive assessment of the test model ,as well as the early warning capacity and the optimal cut‐off level of laboratory indexes in critical HFMD children .Results The AUC of the Logistic regression model (Y ) established based on white blood cell ,neutrophil ,myoglobin ,creatinine for early predicting the death risk in critical HFMD children patients was 0 .847 (95% CI :0 .783 - 0 .911) ,which indicating that its diagnostic value was superior to single index .Conclusion The diag‐nostic value of the Y model established based on four indexes of white blood cell count ,neutrophile granulocytes count ,myohemo‐globin and creatinine is superior to any single index ,which has the better early warning value for the death risk in children with crit‐ical HFMD .
