OBJECTIVETo investigate the leukogenic function of Shuanghuang Shengbai (SHSB) granule and the related mechanisms.

METHODMouse leukopenic models were induced by radiation. Mice were divided into normal control group, model control group, positive control group-Li kejun tablet group and three different dose (high, middle, low-dose) groups of SHSB granule. The peripheral hemogram, thymus index (TI), spleen index (SI), bone marrow nucleated cell (BMNC) and colony forming unit-spleen (CFU-S) were evaluated. The proliferation of bone marrow cells was determined. The in vitro cultured colony forming unit granulocyte macrophage (CFU-GM) was estimated. The index of CD34+ cell in BMNC were determined by flow cytometry. The ultra-micro structure of bone marrow were observed by electromicroscope.

RESULT(1)SHSB rranule could increase the WBC of model mice; (2)SHSB granule could increase BMNC and promote the proliferation of bone marrow cell; (3)SHSB granule could increase CFU-S, CFU-GM and CD34+ cell index in BMNC of model mice significantly; (4)SHSB Granule could also protect the bone marrow hemotopoietic microenvironment from the harm of radiation; (5)SHSB granule could increase the SI of model mice, indicating the enhancement of immunological function.

CONCLUSIONSHSB granule has apparent leukogenic function. The mechanism may be related to enhancing the proliferation of hematopoietic cells and protecting the bone marrow hemotopoietic microenvironment.

This study was purposed to analyze the clinical characteristics of multiple myeloma (MM) patients with and without renal impairment (RI) and to investigate the effect of bortezomib (Bor) on MM with RI. Clinical data of 39 MM patients (15 cases with RI, 24 cases without RI) received treatment of Bor in department of hematology in our hospital from Jan 2007 to Aug 2011 were collect and analyzed in term of clinical characteristics, curative efficacy, outcome of renal impairment and toxic reaction associated to chemotherapy. The results showed that (1) the obvious difference of the disease type, the creatinine, uric acid, serum calcium and β2-microglobulin levels existed in patients with and without RI, while there were no significant difference in hemoglobin and globin levels; (2) there were no significant difference in overall reaction rate and overall survival rate between MM patients with and without RI, however the median survival time of patients without RI was longer than that of patients with RI; (3) the RI could be reversed after the treatment with Bor, and the effect was most obvious after the first cycle. 20% MM patients with RI had recovered from RI after the first cycle; and the recovery rate from RI got up to 38.4% after the second cycle. The decline of creatinine levels had no difference between MM patients with or without RI after the second cycle. (4) The adverse events included gastrointestinal symptoms, peripheral neuropathy, thrombocytopenia and infection. There was also no difference between the 2 groups. It is concluded that Bor-based regimens for the MM patients with RI are effective and safe, and the renal function would be reversed after 2 cycle of Bor-based regimen.

The aim of this study was to investigate the clinical situation of invasive fungal infections in patients with hematological malignancies, and discuss the susceptible factors and precautions. 541 patients with hematological malignancies from 2008 Jan to 2011 Dec in hospital 307 of Chinese PLA were statistically retrospectively analyzed in term of clinical manifestation, image examination, culture results of secretions, therapy and so on. The results showed that 63 out of 541 patients got invasive fungal infections. The respiratory tract and intestinal tract were the most common infection sites (62.34 and 19.48, respectively); Candida albicans (66.67) and Candida glabrata (12.82) were the most common pathogens. It is concluded that the main risk factors are as follows: primary diseases, chemotherapy, glucocorticoid, leukopenia after chemotherapy, applications of broad-spectrum antibiotics and aging. It is suggested that a stratification of risk factors is helpful in preventing and treating invasive fungal infections.

To explore hemorrhage risk and the clinical significance of abnormal change of prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB), plasma thrombin time (TT) and d-dimer (D-D) in de novo acute leukemia (except for APL), the different bleeding manifestations of 114 cases of de novo acute leukemia with different coagulation indexes were analyzed retrospectively. The correlation between these blood coagulation indexes and the possible correlative clinical characteristics were analysed, including age, sex, type of acute leukemia, initial white blood cell(WBC) and platelet(Plt) count, the proportion of blast cells in bone marrow and cytogenetic abnormality of patients at diagnosis. The results indicated that the incidence of abnormal blood coagulation was as high as 78.1% for de novo AL patients. These patients with 5 normal blood coagulation indexes may have mild bleeding manifestation, but the more abnormal indexes, the more severe bleeding. Both PT and D-D were sensitive indexes for diagnosis of level II bleeding. Incidence of abnormal blood coagulation significantly correlates with the proportion of blast cells in bone marrow (χ(2) = 4.184, OR = 1.021, P < 0.05) and more with D-D (P < 0.01), while age, sex, type of AL, WBC count, Plt count and abnormality of cytogenetics did not correlate with abnormal blood coagulation. It is concluded that the coagulation and fibrinolysis are abnormal in most patients with de novo acute leukemia. More abnormal indexes indicate more severe bleeding, and both PT and D-D are sensitive indexes for diagnosis of level II bleeding. Higher proportion of blast cells in bone marrow predicts higher incidence of abnormal blood clotting. Acute leukemia with elderly age, high white blood cell count and adverse cytogenetics do not predict severer abnormal blood clotting. Detection of PT, APTT, TT, FIB, and D-D may help to judge whether the patients are in a state of hypercoagulability or disseminated intravenous coagulation, which will provide experiment evidences for early intervention and medication.

OBJECTIVETo observe the therapeutic effect and major complications of haploidentical nonmyeloablative allogeneic peripheral blood stem cell transplantation (NST) for refractory or relapsed leukemia.

METHODSThe results of 30 patients, including 14 cases of acute myeloid leukemia (AML), 11 cases of acute lymphoblastic leukemia (ALL), 5 case of chronic myelogenous leukemia (CML) (accelerated and blastic phase) with refractory or relapsed leukemia (RF/RL) who underwent haploidentical NST from August 2000 to April 2009 were analyzed. The conditioning regimen consisted of fludarabine (flu), antithymocyte globulin (ATG), cyclophosphamide (CTX), total body irradiation (TBI) and cytarabine (Ara-C) or myleran (Bu). Graft-versus-host disease (GVHD) prevention programmes consisted of Cyclosporine (CsA), mycophenolate mofetil (MMF), CD25 monoclonal antibody combined with mesenchymal stem cells (MSC).

RESULTSTwenty six cases of patients were full donor engraftment and 4 cases mixed chimerism into full donor chimerism. The average duration of neutrophil >0.5×10⁸/L after NST was 11 (9-16) days, and platelet >20×10⁸/L 17 (12-60) days. Upon follow-up of 16 to 120 months, 12-month transplant-related mortality (TRM) was 46.7%, acute Ⅱ-Ⅳgraft-versus-host disease (aGVHD) incidence was 40.0%. The probability of 3-year disease relapse, EFS and overall survival (OS) rates were 16.7%, 46.2% and 50.0% respectively.

CONCLUSIONHaploidentical NST could improve OS and EFS of refractory or relapsed leukemia and reducce TRM to some extent.

OBJECTIVETo evaluate the influence of Tinglizi on collagen volume fraction (CVF) and perivascular collagen volume area (PVCA ) in left ventricle tissue of cardiac hypertrophy induced by abdominal aortic banding in rats.

METHODVentricular remodeling was induced by abdominal aortic banding (AAB) in rats. After 30 day treatment, the systolic blood pressure (SBP), diastolic blood pressure (DBP); heart rate (HR) were measured. The histological assay consisted of the HE stain for determining the myo-cardium cell cross section and collagen stain (Van Gieson' method) for determining collagen content, including collagen volume fracton (CVF) and perivascular collagen volume area (PVCA).

RESULTThe experimental data demonstrated that Tinglizi decreased SBP, DBP, HR and could significantly reduce the total collagen content (CVF, PVCA) and lessen the myocardium cell cross section (P < 0.05).

CONCLUSIONTinglizi may decrease the total collagen content of ventricle and attenuate the ventricular remodeling induced by abdominal aortic banding.

OBJECTIVETo investigate the association between HLA-DQA1 gene polymorphism and the outcomes of hepatitis B virus infection in Chinese Han population.

METHODSA total of 180 consecutive patients with biopsy-proven hepatitis B virus infection (120 patients with chronic hepatitis B and 60 patients with asymptomatic HBV carrier) and 60 subjects who resolved from HBV infection spontaneously were studied. Genotype of human leukocyte antigen(HLA)-DQA1 was detected by polymerase chain reaction sequence specific primer(PCR-SSP).

RESULTS(1) The frequency of HLA-DQA1 * 0201 allele in chronic hepatitis B group was significant higher than the frequency in resolved from HBV infection spontaneously group (38.3% vs. 5.8%, P < 0.001, A = 10.04, 95% CI: 4.48-22.48). The frequency of HLA-DQA1 * 0102 allele in chronic hepatitis B group was significant lower than the frequency in resolved from HBV infection spontaneously group (9.6% vs. 36.7%, P < 0.001, A = 0.183, 95% CI: 0.10-0.32). (2) The frequency of HLA-DQA1 * 0201 allele in chronic hepatitis B group was significant higher than the frequency in asymptomatic HBV carrier group (38.3% vs. 7.5%, P < 0.01, A = 7.667, 95% CI:3.7-15.87). The frequency of HLA-DQA1 * 0102 allele in chronic hepatitis B group was significant lower than the frequency in asymptomatic HBV carrier group (20% vs. 9.6%, P < 0.01, A = 0.424, 95% CI: 0.23-0.79).

CONCLUSIONHLA-DQA1 gene polymorphism may play an important role in the outcomes of hepatitis B virus infection in-Chinese Han population. The HLA-DQA1 * 0102 allele could keep individuals away from HBV infection, and HLA-DQA1 * 0201 allele could aggravate persistant infection of HBV and hepatic inflammatory.
