OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).
METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.
RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].
CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

The present study aimed to investigate the role of platelet-activating factor (PAF) in progesterone synthesis and vascular endothelial growth factor (VEGF) expression in rat luteal cells. Immature (25-28 days old) female Sprague-Dawley rats were injected subcutaneously with 50 IU pregnant mare serum gonadotrophin (PMSG), and 25 IU human chorionic gonadotrophin (hCG) 48 h later, to induce follicular development and luteum formation. On day 6 after hCG administration (the day of hCG administration was the first day), the rats were killed by guillotine and the ovarian luteal cells were collected. After incubation for 24 h, luteal cells were incubated without or with different doses (0.1 μg/mL, 1 μg/mL, 10 μg/mL) of PAF at 37 °C (5% CO(2)) for 24 h, and then progesterone concentration was evaluated by radioimmunoassay (RIA); apoptotic rate and VEGF mRNA expression in luteal cells were assessed by flow cytometry and RT-PCR, respectively. The results showed that PAF promoted progesterone production, with a maximal effect at 1 μg/mL (P<0.05); PAF increased apoptotic rate but not in a dose-dependent manner, and 10 μg/mL PAF enhanced apoptotic rate significantly (P<0.05); furthermore, PAF stimulated VEGF mRNA expression in luteal cells, especially at 1 μg/mL (P<0.01). It is suggested that PAF regulates progesterone synthesis and VEGF mRNA expression in luteal cells to mediate corpus luteum formation in rat ovary.

OBJECTIVETo investigate osthole effect on femoral tissue resorption activity of rat in vitro.
METHODSSix SD rats weighted (80 ± 5) g were used to isolate and culture femoral tissue (diaphyses and metaphysis) in vitro. The cultured tissue were devided into control group, estradiol group and osthole group. The femoral tissue was treated with final concentration of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol culture in vitro at 48 hours after cultured. Tartrate-resistant acid phosphatase (StrACP) activity, glucose and Lactic acid content, StrACP, MCSF (Macrophage colony stimulating factor) and CTSK (Cathepsin K) mRNA was detected by Real-Time RT-PCR were detected.
RESULTSConcetration of Alkaline phosphatase activity were 2226 and 2498 in 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol respectively. As compared with control group, the activity of StrACP of 1 x 10(-5) mol/L osthole and 1 x 10(-8) mol/L estradiol were inhibited at 6, 9, 12 days (P < 0.05); under treatment of in l x 10(-5) mol/L osthole, the content of Lactic acid were increased and the content of glucose were decreased at 3, 6, 9 days (P < 0.05); StrACP, MCSF and CTSK mRNA expression level were inhibited at 6, 9 days (P < 0.05).
CONCLUSIONOsthole can inhibit bone resorption and raise the level of nutrition metabolism of femurs tissue.

AIMTo investigate the effects of soy isoflavones (SI) on the expression of Bax mRNA and Ca(2+) -ATPase activity in ovaries of perimenopause rats.
METHODSThe animal model of perimenopause rats was established by unforced aging. 12 month-old presenilins female Wistar rats were administered by intragastric (ig) with low (500 mg/kg), middle (158 mg/kg) and high (500 mg/kg) does of SI for 8 weeks. The expression of Bax mRNA in ovaries were detected by RT-PCR. Ca(2+) -ATPase activity in ovaries and MDA content and SOD activity in serum were detected by chemi-chromatometry.
RESULTSIntervention of SI could significantly decrease the expression of Bax mRNA in ovaries and MDA content in serum, increase Ca(2+) -ATPase activity in ovaries and SOD activity in serum of presenilins rats (P < 0.05 or P < 0.01).
CONCLUSIONSoy isoflavones could down-regulate the expression of Bax mRNA and increase Ca(2+) -ATPase activity in aged ovaries. It is probably one of the mechanisms to improve the function of aged ovaries in perimenopause rats.

PURPOSE: Modafinil is a wake-promoting agent that has been proposed to improve cognitive performance at the preclinical and clinical levels. Since there is insufficient evidence for modafinil to be regarded as a cognitive enhancer, the aim of this study was to investigate the effects of chronic modafinil administration on behavioral learning in healthy adult rats. METHODS: Y-maze training was used to assess learning performance, and the whole-cell patch clamp technique was used to assess synaptic transmission in pyramidal neurons of the hippocampal CA1 region of rats. RESULTS: Intraperitoneal administration of modafinil at 200 mg/kg or 300 mg/kg significantly improved learning performance. Furthermore, perfusion with 1mM modafinil enhanced the frequency and amplitude of spontaneous postsynaptic currents and spontaneous excitatory postsynaptic currents in CA1 pyramidal neurons in hippocampal slices. However, the frequency and amplitude of spontaneous inhibitory postsynaptic currents in CA1 pyramidal neurons were inhibited by treatment with 1mM modafinil. CONCLUSIONS: These results indicate that modafinil improves learning and memory in rats possibly by enhancing glutamatergic excitatory synaptic transmission and inhibiting GABAergic (gamma-aminobutyric acid-ergic) inhibitory synaptic transmission.

OBJECTIVETo study the global evolutionary characteristics of hemagglutinin gene HA1 of influenza H1N1 infecting different species during 2000-2009.
METHODSThe target sequences were downloaded from NCBI and analyzed using bioinformatic software to construct the phylogenetic tree.
RESULTSThe HA1 amino acid sequences of influenza H1N1 contained four mutated antigenic sites and receptor-binding sites, and the novel influenza virus shared most of the mutated amino acid sites with swine H1N1 influenza virus.
CONCLUSIONThe HA1 gene of novel influenza virus might originate from the early swine H1N1 influenza virus from North America, and in the evolutionary process, a number of important sites of HA1 gene mutated to result in the outbreak of influenza.

OBJECTIVETo study the clinical characteristics, risk factors and therapeutic outcome of Philadelphia chromosome-positive adult acute lymphoblastic leukemia (Ph(+)aALL).
METHODSThe clinical data of 117 newly diagnosed adults with Ph(+)ALL in our hospital between January 1995 and December 2009 were retrospectively analyzed. And their prognoses were followed up.
RESULTSThere were 117(16.1%) of 727 aALL patients diagnosed as Ph(+)aALL. Among the 117 cases, 64.1% patients were classified as pre-B immunophenotype and 31.3% as common B immunophenotype, 37.5% patients with co-expression of myeloid antigens (CD13 or CD33), and 98.4% patients with positive CD34. The complete remission (CR) rate after 1 or 2 cycles of induction chemotherapy was 62.2% in Ph(+)aALL group versus 82% in Ph(-)aALL group (P = 0.000). The median disease-free survival time of Ph(+) group was 6 months and the median survival time was 9 months. Sole karyotype abnormality subgroup t(9;22) accounted for 53% of all Ph(+)aALL patients and additional karyotype abnormality subgroup, t(9;22) plus other chromosome variation, accounted for 47%. Patients in sole karyotype abnormality subgroup had slightly lower CR rate (59.6% vs 62.5%, P = 0.768), longer median survival time (7 months vs 4 months, P = 0.158), and higher 3-year overall survival rate (27.3% vs 14.4%, P = 0.271). For the myeloid antigen co-expressed patients and the only lymphocytic antigen expressed ones, CR rate was 56.0% and 61.5% (P = 0.750), the median survival time was 5 months and 4 months (P = 0.182), and the 3-year overall survival rate was 16.0% and 15.0% (P = 0.354), respectively. In the imatinib plus combination chemotherapy treatment group, 81.3% patients achieved CR, compared with that of 58.3% in patients treated with only traditional combination chemotherapy (P = 0.083). The median survival time was 9.5 months and 6 months (P = 0.003) in these two subgroup, and 3-year overall survival rate was 52.2% and 10.3% (P = 0.029), respectively. For the patients receiving allo-HSCT after CR and that receiving traditional consolidation chemotherapy, the median survival time was 15 months and 6 months (P = 0.000), and the 3-year overall survival rate was 62.0% and 10.3% (P = 0.000), respectively. For the patients receiving imatinib as consolidation-maintenance treatment and that receiving allo-HSCT, the median survival time was 12 months and 15 months (P = 0.300), and the 3-year overall survival rate was 64.7% and 62% (P = 0.505), respectively.
CONCLUSIONOf all adult ALL patients, the Ph(+) subgroup accounted for about 16.1%, which have unfavorable prognosis such as lower CR rate and shorter survival duration under traditional chemotherapy. Neither additional chromosome abnormalities to t(9;22) nor co-expression of myeloid antigen had negative effect on CR rate and survival duration. Addition of imatinib to the therapy was beneficial to improve the CR rate and survival duration. Either receiving imatinib as consolidation-maintenance treatment or allo-HSCT after complete remission can improve long-term survival rate of Ph(+) adult ALL group significantly.
