Seven meroterpenoids and five small-molecular precursors were isolated from Penicillium sp., an endophytic fungus from Dysosma versipellis. The structures of new compounds, 11beta-acetoxyisoaustinone (1) and isoberkedienolactone (2) were elucidated based on analysis of the spectral data, and the absolute configuration of 2 was established by TDDFT ECD calculation with satisfactory match to its experimental ECD data. Meroterpenoids originated tetraketide and pentaketide precursors, resepectively, were found to be simultaneously produced in specific fungus of Penicillium species. These compounds showed weak cytotoxicity in vitro against HCT-116, HepG2, BGC-823, NCI-H1650, and A2780 cell lines with IC 50 > 10 micromol x L(-1).

OBJECTIVECytokine mediated cell immunity is the main mode of anti-tumor immunity in organism, and the disequilibrium of cytokine network is the main cause of tumor cells escaping immunologic surveillance. High mobility group box 1 (HMGB1), a nuclear protein, has recently been identified as an important mediator of local and systemic inflammatory diseases when released into the extracellular milieu. In the present study, the investigators explored the clinical significance of alteration in the serum levels of HMGB1 in childhood acute lymphocytic leukemia (ALL) and the mechanism of HMGB1-induced tumor necrosis factor (TNF)-alpha secretion in leukemic cells.

METHODSThe serum levels of HMGB1 in healthy children and childhood ALL were assayed by Western blotting. K562 leukemic cells were stimulated with recombinant HMGB1 protein in vitro, and the secretion of TNF-alpha was determined by using ELISA. The effects of HMGB1 on activation of p38, c-Jun amino-terminal kinase (JNK), and extracellular-signal regulated protein kinase (ERK) and mitogen-activated protein kinase (MAPK) in K562 cells were assayed by using Western blotting. The effects of inhibitors specific for the MAPK on HMGB1-induced TNF-alpha secretion were assayed by using ELISA.

RESULTSThe serum levels of HMGB1 were significantly higher in ALL initial treatment group (n = 15, 43.78 +/- 4.62 microg/ml) than those in healthy control group (n = 15, 0.60 +/- 0.48 microg/ml, P < 0.01) and ALL complete remission group (n = 15, 0.89 +/- 0.62 microg/ml, P < 0.01). No significant difference was found between the healthy control group and ALL complete remission group in HMGB1 levels (P > 0.05). TNF-alpha started to become detectable at 2 h and was still increasing at 16 h after HMGB1 (1 microg/ml) treatment in K562 cell culture. TNF-alpha was also secreted from K562 cells in a dose-dependent manner after HMGB1 (1 ng/ml-1 microg/ml) exposure. HMGB1 induced the phosphorylation of p38, JNK and ERK in k562 cells. Inhibitors specific for the JNK (SP600125), MEK (PD98059), and p38 MAPK (SB203580), abrogated HMGB1-induced TNF-alpha secretion.

CONCLUSIONSThe measurement of serum HMGB1 is helpful to evaluate the prognosis of the childhood ALL. HMGB1 stimulates leukemic cells to secrete TNF-alpha through a MAPK-dependent mechanism.

OBJECTIVETo explore the acting mechanism of viscera purging method (VP) in purging Fu-organs and benefiting Fei from integral, cellular and molecular levels.

METHODSForty SD rats were equally divided into four groups randomly: the normal group, the model group, the unhitch group and the VP group. Except those in the normal group were untreated, rats were established to intestinal obstruction model by incomplete ligation of the rectum in vitro. The ligation was relieved 48 h after operation in the unhitch group and the VP group, and the animals were fed continuously on routine. Meanwhile, Dachengqi Decoction (DD) 2 ml was given twice a day to the VP group for 2 days. Finally, the serum interleukin 8 (IL-8) and mRNA expression of tumor necrosis factor-alpha (TNF-alpha) in the lung tissue were detected by radioimmunoassay and RT-PCR respectively. Besides, the number of pulmonary alveolar macrophages (PAM) in the bronchial alveolus lavage fluid (BALF) was counted and their death rate calculated.

RESULTSCompared with the normal control, the serum IL-8 content in lung tissue in the model rats were remarkably higher (P < 0.01); however, the VP group showed the lowest level of IL-8 content and the highest was shown in the model group. Number of PAM in BALF was higher and its death rate was lower in the VP group than that in the unhitch groups (both P< 0.05). The expression of TNF-alpha mRNA was sinificantly higher as compared with that in the normal group, and lowered after administration of DD.

CONCLUSIONViscera purging method could protect the injured lung tissue to some extent.

Adipose tissue is not simply a depot of energy, but is an active endocrine organ. The adipokines play an important role in the pathogenesis of metabolic syndrome. The proinflammatory adipokines secreted from expanded visceral adipose tissue directly induce insulin resistance and vascular injuries. A better understanding of the endocrine function of adipose tissue may lead to more rational therapy for metabolic syndrome.

OBJECTIVETo evaluate the efficacy of salvaged allogeneic hematopoietic stem cell transplantation (allo-HSCT) for refractory/recurrent acute myeloid leukemia (AML).

METHODSA total of 45 patients with refractory/recurrent AML were enrolled from September 2006 to April 2010. The median blasts in bone marrow (BM) were 36% (20% to 92%) before conditioning. The donors were identical siblings (6) or unrelated ones (9) or haploidentical family members (30). Conditioning regiments were individualized according to patients' status, the regimen with high-dose cytarabine plus BuCy/CY was mostly used (20). The patients with impaired organ function received above regimen except using fludarabine instead of cyclophosphamide (16). FLAG followed by reduced-intensified BuCy was employed for the recipients with more than 40% blasts in BM (6) to reduce leukemia burden. TBI/CY or TBI/Fludarabine was used for the recipients with extramedullary infiltration of leukemia or multidrug resistant leukemia. G-CSF, MTX, NVT, Vm26, Acla or Thaltipa was added into conditioning regiments according to leukemia character.

RESULTSAll but 2 patients attained durable engraftment. The incidence of grade II to IV aGVHD and cGVHD were 34%, 59.1%, respectively. With median follow-up 30 (0.5 - 57) months, the relapse rate was 29.2%. Twenty-nine of 45 (60.2%) patients remained in complete remission since salvaged HSCT. Three-years disease-free survival and overall survival were 60.2% and 62.6%, respectively.

CONCLUSIONOur results indicated that the combination of salvaged HSCT with prophylactic immunotherapy might be a promising modality for treatment of refractory/recurrent AML, even with high leukemia burden.

OBJECTIVETo investigate the relationship between three types of bcr/abl fusion transcripts and clinical manifestation in chronic myeloid leukemia (CML).

METHODM-, m- and micro -bcr/abl fusion transcripts were detected by reverse transcriptase-polymerase chain reaction (RT-PCR) technique in 537 fresh bone marrow samples of patients suspected CML clinically.

RESULTSOf 573 patients, 479 expressed M-bcr/abl transcripts, among whom 370 were in chronic phase (CP), and 109 in accelerated (AP)/blastic phase (BP). The percentages of patients with b2a2 transcripts in CP and AP/BP were 32.4% (120/370) and 36.7% (40/109) (P > 0.05). The b2a2 transcript patients in blastic crisis were 52.6% (10/19) for lymphoblastic and 33.3% (30/90) for myeloblastic (P > 0.05). The platelet count of untreated patients with b3a2 isoform [(485.9 +/- 333.8) x 10(9)/L, n = 125] was distinctly higher than those with b2a2 isoform [(380.5 +/- 321.9) x 10(9)/L, n = 62] (P < 0.05). 66.0% (31/47) and 64.4% (29/45) of the patients in CP and AP/BP respectively co-expressed M- and m-bcr/abl transcripts (P > 0.05). One patient expressed only m-bcr/abl transcript was of typical acute myeloblastic leukemia (AML). Both two micro -bcr/abl(+) patients were of typical CML.

CONCLUSIONSAlmost all typical CML patients express M-bcr/abl transcripts, most of them coexpress M-bcr/abl and m-bcr/abl transcripts, a few possesses only micro -bcr/abl fusion gene. m-bcr/abl(+) are usually associated with AML or CML in myeloblastic crisis besides acute lymphoblastic leukemia (ALL). Patients with b3a2 isoform are prone to higher platelet count before treatment.
