Objective To investigate the clinical characteristics and treatment efficacy in newly diagnosed multiple myeloma (MM). Methods The clinical data and treatment methods of 176 patients with newly diagnosed MM were retrospectively analyzed. Results The most common chief complaint in the patients with MM was bone pain. 26.1 % (46/176) patients once experienced misdiagnosis. The overall response rate (ORR) was 65.9 % (116/176), the ORR of bortezomib group (81.0 %, 34/42) was significantly higher than that of M2 regimen group (61.8 %, 34/55) and VAD regimen group (60.8 %, 48/79) (P<0.05). Between normal renal function subgroup and renal insufficiency subgroup in bortezomib group, the efficacy was no significant difference (P>0.05). The most common adverse reactions included hematologic toxicity, infection and peripheral neurotoxicity. Multiple organ failure was the main cause of death (47.1 %, 16/34). Conclusions The clinical manifestations of MM are complex and diverse, which is easy to be misdiagnosed. Molecular genetic abnormalities are closely related to prognosis. Proteasome inhibitor bortezomib can improve the curative effect and not be affected by renal function. To prolong the survival time of the patients needs to prevent and control the infection and renal insufficiency actively.

Background and purpose:Endometrial carcinoma is a common malignant tumour in women and expresses COX-2,CDK4;the expressions are associated with the development of the tumour. Mifepristone can inhibit the growth of the tumours, but its mechanisms are not very clear, We investigated the inhibitory effect of antiprogestins mifepristone n the growth of human endometrial carcinoma cell line HHUA xenografted in nude mice of and the expressions of COX-2,CDK4,the purpose was to find out whether or not mifepristone could influence the expressions of COX-2,CDK4. Methods:Human endometrial carcinoma HHUA cells were cultured in vitro.The models of xenografted tumor were established by the transplantation of human endometrial carcinoma HHUA cell on nude mice. The nude mice were randomly divided into two groups to receive either refined peanut oil (control group), or daily mifepristone for six weeks, respectively . The sizes of xenograft were measured in the pre-and post-treatment. The changes of morphology were observed by glass microscopy. The positive immunostaining for COX-2 and CDK4 were evaluated semiquantitatively by using an immunohistochemical scoring system (HSCORE) that it incorporated both the intensity and the distribution of specific staining.Results:After 6 weeks of treatment , the size of the xenografts in MIF group were 115.25?10.97 mm 3 ,compared with 313.25?43.92 mm 3 in the control group (P

Objective To investigate the efficacy and safety of a schedule of 2 cycles' high-dose dexamethasone (HD-DXM) as an initial therapy in adults immune thrombocytopenia (ITP), and compare with conventional dose prednisone therapy. Method A total of 59 newly diagnosed ITP patients were divided into 2 groups randomly. In 30 patients ( Dexamethasone group), oral HD-DXM was administered at 40 mg/d for 4 consecutive days, repeated one week later, and then failed to maintain. In the remaining 29and then gradually tapered. Results For short-term efficacy, after 1 and 2 weeks of treatment, the response rate in Dexamethasone group was significantly higher than that in Prednisone group (50. 0% vs 24. 1%, P ＜0. 01; 73.3% vs 55.2%, P ＜0. 05 ), while 3 weeks later, there was no remarkable difference between the two groups(83.3% vs 68.9%, P ＞ 0. 05 ), though the response rate in Dexamethasone group remained higher. For long-term effect, at the end of the 2nd and 3rd months of follow-up, the relapse rate in Dexamethasone group was significantly lower than that in Prednisone group(24. 0% vs 40. 0%, P ＜ 0. 05;32.0% vs 65. 0%, P ＜ 0. 01 ), while at the end of the 1st month of follow-up, there was no significant difference( 16. 0% vs 20. 0%, P ＞0.05 ). In addition, it's well tolerated and no complications such as severe infection or Cushing syndrome were complained in Dexamethasone group. Conclusion HD-DXM possesses an advantage over conventional dose prednisone therapy in efficacy and safety.

Objective To investigate the curative effect of the Idarubicin(IDA) in combination with Am-Cand VP16 (IAE) regimen for treatment on refractory acute myelecytic leukemia. Methods Idarubiein 7 mg/m2 iv gtt for 3 days, Ara-C 100 mg/m2 and VP16 100 mg/d iv gtt for 5 days continuously were used as one course.Results Among 17 refractory leukemia patients complete remission was achieved in 9 patients and partial remission in 4 patients, but no remission in 3 patients and one patient died of cerebral hemorrhage after one-two courses of the treatment. Conclusion The IAE regimen for treatment of refractory acute myelocytic leukemia is an effective therapy. The major toxic side effects encountered were marrow suppression,neutropenia and thrombocytopenia. The toxic side effects in heart, liver and kidney were not found.

Objective:To investigate the clinical characteristics and prognosis of Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) patients with additional chromosomal abnormalities.Methods:The data of 351 CML patients with Ph-positive in the Affiliated Hospital of Qingdao University from January 2009 to January 2019 were retrospectively analyzed. The bone marrow chromosomal karyotype analysis of all patients was performed by using R-banding technique. The clinical characteristics and karyotype of Ph-positive CML patients with additional chromosomal abnormalities at initial diagnosis were summarized, and Kaplan-Meier was used to analyze the differences in overall survival (OS) of patients with different karyotypes.Results:Among 351 patients with Ph-positive CML, 32 (9.1%) cases had variant translocation. At initial diagnosis, 47 cases had additional chromosomal abnormalities including 29 cases in chronic phase accounting for 9.15% (29/317) of all patients in chronic phase, 3 cases in accelerated phase accounting for 25.00% (3/12) of all patients in accelerated phase, 15 cases in blast crisis accounting for 68.18% (15/22) of all patients in blast crisis; there was a statistically significant difference in the chromosomal abnormalities rate of all different phases ( χ2=50.799, P<0.05). Among 47 Ph-positive CML patients with additional chromosomal abnormalities, 13 patients had complex karyotypes with more than 3 additional chromosomal abnormalities, the proportion of complex karyotypes in chronic phase, accelerated phase and blast crisis was 13.79% (4/29), 33.33% (1/3) and 53.33% (8/15), respectively, and the difference was statistically significant ( χ2=9.26, P<0.05). The study showed that the most common additional chromosomal abnormalities in chronic phase were double Ph (48.28%, 14/29) and -Y (10.34%, 3/29), while the most common chromosomal abnormalities in the blast crisis were +8 (26.67%, 4/15) and double Ph (26.67%, 4/15). Kaplan-Meier survival analysis showed that at initial diagnosis the OS time of patients with additional chromosomal abnormalities was worse than that of those with the non-additional chromosomal abnormalities group ( χ2 = 61.138, P<0.05). The OS of patients with complex karyotypes for Ph - positive CML patients with additional chromosomal abnormalities at initial diagnosis was worse than that of patients with non-complex karyotypes, and the difference was significant ( χ2 = 4.945, P < 0.05). Conclusions:The additional chromosomal abnormalities is closely related to the progression of CML, and the prognosis of CML patients with additional chromosomal abnormalities is poorer than that of patients with only Ph translocation. Moreover, the more complex the additional chromosomes are, the more likely blastic changes are, and the poorer prognosis. And additional chromosomeal abnormalities during the treatment of CML patients may also lead to the progression of blastic changes.

OBJECTIVETo study the relationship between soluble resistance-related calcium-binding protein (sorcin) gene and multidrug resistance gene (mdr1), and their significance in clinical drug resistance and prognosis of acute myeloid leukemia (AML).

METHODSAmplification of sorcin gene and mdr1 gene in K562/A02 cell detected by Northern blot, were monitored by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) in 65 AML patients and 27 normal controls, with their relationship and clinical outcame analyzed.

RESULTSThe amplification of sorcin gene and mdr1 gene in AML patients were significantly higher than that in the normal control, which were related to clinical drug resistance and prognosis. The amplification of sorcin gene was related to the amplification of mdr1 gene in the two groups. The clinical drug resistance incidence rate and complete remission rate were 92.9% and 7.1% in sorcin(+)/mdr1(+) group. They were 8.6% and 91.4% in the sorcin(-)/mdr1(-) group (P < 0.001).

CONCLUSIONThe co-amplification of sorcin and mdr1 gene can be taken as a good indicator of clinical drug resistance and prognosis of AML.

OBJECTIVETo study the relationship between the expression of soluble drug resistance-related calcium-binding protein (sorcin) gene and the clinical multidrug resistance in acute leukemia (AL).

METHODSA semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) was used to investigate the transcription levels of the human sorcin gene in 95 AL patients and 27 controls.

RESULTSSorcin gene expression was significantly higher in AL patients than in normal contrls (P < 0.001), and higher in relapsed/refractory acute myeloid leukemia (AML) patients than in those newly diagnosed or in complete remission. Sorcin gene overexpression was significantly lower in non-resistant patients than in resistant ones (P < 0.001). CR rates of these two groups were 20.0% and 80.0%, respectively. Sorcin gene expression was higher in AML-M(5) patients than M(2), M(3), M(4) patients.

CONCLUSIONSorcin gene overexpression is significantly associated with clinical multidrug resistance and prognosis, it is one of the indicators for predicting prognosis of AL patients.

OBJECTIVETo compare the efficacy and toxicity of the chemotherapeutic regimen containing pirarubicin and mitoxantrone on the treatment of relapsed or refractory acute myeloid leukemia (AML) in adults.

METHODSIn this open prospective multicentre study, we randomly assigned patients with relapsed or refractory AML to receive TAE regimen (pirarubicin+cytarabine+etoposide) versus MAE regimen (mitoxantrone + cytarabine + etoposide). The efficacy and toxicity were compared between the two groups.

RESULTS56 patients entered this clinical trial. The complete remission (CR) rate on TAE arm was 79.0% versus 55.6% on MAE arm with the overall response (OR) rates of 86.8% versus 88.9%, respectively. The CR was higher on TAE arm (P=0.035) but with no significant difference between the two groups regarding the overall response (OR) rate. The regimens were well tolerated in both groups. Hematologic and non-hematologic toxicity were similar except relatively lower the mean dosage of G-CSF, red blood cells and platelets transfusion on TAE arm. No significant differences were seen between the two groups regarding the overall survival and relapse free survival rates.

CONCLUSIONTAE regimen might be an effective salvage therapy in patients with relapsed or refractory AML.

Objective: To investigate the effect of immunophenotyping on prognosis of multiple myeloma (MM) patients treated with bortezomib regimen as main treatment. Methods: Seventy-six MM patients in the Department of Hematology in the Affiliated Hospital of Qingdao University from January 2012 to January 2017 were retrospectively analyzed. The effects of the expressions of CD45, CD56 and other factors on progression free survival (PFS) and overall survival (OS) in MM patients treated with bortezomib-containing regimen were also analyzed. Results: Univariate analysis showed that statistical differences of the median PFS (12 months vs. 19 months, P < 0.001) and median OS (19 months vs. 23 months, P= 0.001) were significant in the group of CD45 positive and negative of MM patients; the median PFS (14 months vs. 21 months, P= 0.014) and median OS (16 months vs. 25 months, P= 0.026) for MM patients with hemoglobin (Hb) < 100 g/L and Hb ≥ 100 g/L were statistically significant; the median PFS (13 months vs. 18 months, P= 0.004) and median OS (14 months vs. 24 months, P= 0.008) for MM patients with albumin (ALB) < 35 g/L and ALB ≥ 35 g/L were statistically significant. The median PFS time and the median OS time in female MM patients were shorter than those in male MM patients (13 months vs. 19 months, P= 0.008; 16 months vs. 25 months, P= 0.008). Multivariate analysis showed that female and CD45 positive were the independent poor prognostic factors for PFS and OS in MM patients (P < 0.05). Conclusion CD45 positive and female are important prognostic factors for MM patients treated with bortezomib regimen as main treatment.
