Objective To observe the efficacy of liposomal doxorubicin combined with cyclophosphamide, vincristine and prednisone in the treatment of refractory Non-Hodgkin’s lymphoma.Methods Liposomal doxorubicin (40mg/m2) was given by intravenous drip in the 1st day. Cyclophosphamide (750mg/m2) was given by intravenous injection in the 1st day. Vincristine (2mg) was given by intravenous injection in the 1st day. Prednisone (100mg/m2) was given orally from the 1st to the 5th day. A cycle was repeated every 3 to 4 weeks. Every patient took at least 2 cycles of the regimen.Results A total of 13 patients were assessed in the group. Among them, 7 were completely release (53.8), 4 were partially release (30.67) and 2 remained the same (15.35). The B symptom of 7 patients in the 9 with that disappeared, and that of the other 2 patients was improved obviously. The most common adverse effects were slight gastrointestinal reactions and the grade Ⅲ bone marrow suppression in a few patients. Conclusion The regimen of liposomal doxorubicin combined with cyclophosphamide, vincristine and prednisone is effective in the treatment of refractory Non-Hodgkin’s lymphoma with tolerable toxicity. It may be a salvage chemotherapeutic regimen deserving further study.

Thirty eight adult male rabbits were selected for the experiment. The experimental peptic ulcer was induced by means of injection of 40% acetic acid to the submucosa of the stomach. Animals of the control group were injected with normal saline instead and another control group consisted of normal rabbits without any treatment. The animals were killed by decapitation at different time intervals (3~49 days) after the operation. The adrenal tissues were prepared for histochemical studies from both experimental and control animals. The results were observed as follows:During the early stage of the peptic ulcer, the fascicular and reticular zones were the chief sites in the adrenal cortex where histochemical changes were involved. Three days after the peptic ulcer operation, the cells of the fascicular and reticular zones filled with sudanophilic lipid droplets and cholesterol droplets. Five days after the operation, both of lipid droplets and cholesterol droplets decreased; the content of ascorbic acid increased slightly; and the activity of succinic dehydrogenase also increased. The above changes were most conspicuous in the inner portion of the fascicular zone within ten days. After fourteen days, all the above histochemical changes began to recover and gradually returned to the normal level after eighteen to thirty five days. In the normal saline operation control group, the contents of lipid droplets and cholesterol droplets decreased in the fascicular and reticular zones after three days and returned to normal level during the period of ten to fourteen days after operation for saline injection.The above histochemical changes showed that the adrenal cortex was at an active functional state during the early period of the experimental peptic ulcer.

Objective To explore the efficacy and safety of HAA regimen (homoharringtonine,cytarabine and aclarubicin) in the treatment of 150 newly diagnosed adult acute myeloid leukemia (AML).Methods All patients entered the study from May 1999 to June 2008 were treated with HAA regimen. Coxsurvival analysis was used to estimate the survival rate and differences between M1/M2 and M4/M5 were compared with 2-sided log-rank test. Results Out of the 150 patients, 121 (81%) achieved complete remission (CR). After the first course, CR rate was 68%. The CR rates of 97%, 84% and 38% were achieved in patients with favorable, intermediate and unfavorable cytogenetics, respectively. For the patients with CR, the median follow-up time was 16.5 ( 1.5-100.5 ) months, and the estimated 3-year survival rate was 45%. The estimated 3-year relapse free survival rate was 52% for the 121 patients with CR.Conclusions HAA regimen may be an efficacious and safe regimen with a good toleration in the induction therapy for newly diagnosed AML, and a high CR rate could be achieved with only one or two courses.

OBJECTIVETo evaluate the efficacy and safety of the HAA regimen (homoharringtonine,cytarabine and aclarubicin)as salvage chemotherapy in the treatment of refractory/relapsed acute myeloid leukemia (AML).
METHODSWe retrospectively analyzed 64 patients with refractory/relapsed AML who received the HAA regimen as salvage chemotherapy. The complete remission (CR)rate was analyzed. Kaplan-Meier method was used to estimate overall survival (OS) and relapse free survival (RFS), and the differences were compared by Log-rank test.
RESULTSThe overall CR rate was 70.1%, and 67.1% of the patients attained CR after the first induction course. The early death rate was 0. The median follow-up time was 61 (range:6-120) months. The estimated 3-year OS rate was 46.8% and the estimated 3-year RFS rate was 42.8%. The CR rates of patients with favorable/intermediate and unfavorable cytogenetics were 76.4% and 33.3%, respectively. The 3-year OS of favorable/intermediate and unfavorable group were 53.7% and 10.0%, respectively. The median survival time of unfavorable group was only 8 months. The side effects associated with the HAA regimen were tolerable, in which the most common toxicities were myelosuppression and infection.
CONCLUSIONHAA regimen is associated with a higher rate of CR and longer-term survival and its toxicity can be tolerated. The regimen is suitable for refractory/relapsed AML patients with favorable or intermediate risk .

Objective:
To analyze the prognostic significance of TP53, Bcl-2, Bcl-6, Myc proteins expression by immunohistochemical method (IHC) in diffuse large B cell Lymphoma (DLBCL) .
Methods:
Clinical and pathologic data of 223 patients with DLBCL hospitalized in Zhejiang First Hospital from March 2009 to June 2015 were retrospectively analyzed.
Results:
The 223 cases, a median age of 56 years old with a male predominance, had shown a 39.0% of TP53 positive expression, 38.6% of Myc, 69.1% of Bcl-2, 56.5% of Bcl-6, and 22.7% of Myc/Bcl-2 double expression. According to Hans’ classification, 27.4% were GCB and 72.6% were non-GCB. With a median follow-up of 38 (2-97) months, the 3 and 5 years survival rates were 70% and 66% , respectively. By multivariate analysis, TP53 over-expression and Myc/Bcl-2 double expression were independently associated with poor outcomes. 3-year and 5-year overall survival were 59% and 57% for patients with TP53 positive, 77% and 71% for patients with TP53 negative expression. Patients with non-GCB subtype receiving chemotherapy combined with rituximab had a higher OS than those without rituximab. But rituximab did not improve the prognosis of patients with TP53 positive.
Conclusion
Myc/Bcl-2 double expression and TP53 over-expression are poor prognosis for DLBCL patients. Patients with Myc/Bcl-2 double expression have shorter OS. Patients with non-GCB subtype who received chemotherapy combined with rituximab have a better OS than those without rituximab. But rituximab does not improve the prognosis of patients with TP53 positive.

OBJECTIVETo investigate the expression level of SET gene in patients with acute myeloid leukemia (AML) and evaluate its significance.
METHODSThe expression level of SET gene in 141 de novo AML patients was determined by real time quantitative PCR (RQ-PCR), and its relationship with the clinical features and outcomes of these patients were analyzed.
RESULTSSET gene transcript level was detected in 141 AML patients with the median expression level of 0.86(range 0.02-15.69). AML patients with higher SET gene expression had a higher level of white blood cell (WBC ≥ 100 × 10⁹/L) count than of lower SET gene expression ones (31.0% vs 11.4%, P=0.005). In the 136 patients who received treatment after diagnosis, higher SET gene expression group had lower complete remission rate (50.0%) than of lower expression cohort (73.5%) after two cycles of chemotherapy (P=0.005). Survival analysis showed that patients with higher SET gene expression had significantly shorter overall survival(OS) (10 months vs 22 months, P=0.001) and event-free survival (EFS) (2 months vs 14 months, P=0.005) than of lower SET gene expression ones. Multivariate COX regression analysis showed SET overexpression was an independent prognostic factor for OS. In the patients with the normal karyotype, higher SET expression group also had significantly shorter OS (12 months vs 35 months, P=0.010) and EFS (4 months vs 14 months, P=0.026) than of lower SET expression ones.
CONCLUSIONHigh expression of SET gene was associated with poor prognosis and might be a prognostic molecular marker of AML.

OBJECTIVETo investigate the clinical efficacy of all-trans retinoic acid (ATRA) plus arsenic trioxide (ATO) in induction and maintenance therapy in newly diagnosed acute promyelocytic leukemia (APL).
METHODSA retrospective analysis of 298 newly diagnosed APL patients from the department of hematology, First Affiliated Hospital of Zhejiang University since September 2004 to December 2013, including 177 cases with ATRA plus ATO and 116 ATRA plus chemotherapy (CT), was performed to investigate the clinical efficacy between the low-intermediate (WBC≤10×10⁹/L) and high (WBC>10×10⁹/L) risk APL patients, respectively.
RESULTSFor the low-intermediate risk patients, the relapse rate in ATRA plus CT and ATRA plus ATO are 22.0% and 6.1% (P=0.004), respectively; the 3 years estimated relapse-free survival (RFS) are 78.0% and 92.9% (P=0.021), respectively. For the high risk patients, the relapse rate in ATRA plus CT and ATRA plus ATO are 25.0% and 5.2% (P=0.035), respectively; the 3 years estimated RFS rate were 80.8% and 93.0% (P=0.021), respectively. But the rate of early death (ED), complete remission (CR) and overall survival (OS) between the two therapy protocols had no statistical difference (P>0.05).
CONCLUSIONATRA plus ATO in induction and maintenance therapy might prolong the RFS time of the low-intermediate risk APL patients and decrease the relapse rate of the low, intermediate and high risk APL patients.
