The chemical consituents from Artabotrys hongkongensis were separated and purified by column chromatographies with silica gel, Sephadex LH-20, ODS and RP-HPLC. The structures of the isolated compounds were identified on the basis of physicochemical properties and spectroscopic analysis, as well as comparisons with the data reported in the literature. As a result, 16 sesquiterpenes were isolated and elucidated as blumenol A (1), 4, 5-dihydroblumenol A (2), (6R, 9S)-3-oxo-a-ionol (3), 3-hydroxy-β-ionone (4), dehydrovomifoliol (5), (3R, 6R, 7E) -3-hydroxy-4, 7-megastigmadien-9-one (6), sarmentol F (7), 10-oxo-isodauc-3-en-15-oic acid (8), fukinone (9), petasitolone (10), β-eudesmol (11), trans-3β-(1-hydroxy-1-methylethyl)- 8aβ-methyl-5-methylenedecalin-2-one (12), 10-hydroxyaristolan-9-one (13), aristol-8-en-1-one (14), aristolan-9-en-1-one (15), and aristolan-1, 9-diene (16). This is the first study on the chemical consituents of A. hongkongensis, and all compounds were isolated from the genus Artabotrys for the first time.

OBJECTIVETo analyze retrospectively the therapeutic efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic myelomonocytic leukemia (CMML).

METHODSThe engraftment, graft versus host disease (GVHD), infection, relapse, and survival of 13 CMML patients received allo-HSCT were observed. The clinical outcome of allo-HSCT for CMML was analyzed.

RESULTSThirteen (10 males and 3 females) CMML patients with a median age of 38 years old received allo-HSCT including 4 from HLA-matched unrelated donors, 6 from HLA-matched sibling donors and 3 from haploidentical related donors. All 13 patients achieved engraftment, and the median time of neutrophil engraftment and platelet engraftment were 12 (11-18) days and 15 (10-55) days respectively, acute GVHD occurred in 8 patients. After the median follow-up of 13 (6-29) months, the overall survival, disease free survival and relapse were 53.8%, 53.8%, 7.7%, respectively.

CONCLUSIONAllo-HSCT can improve the survival of patients with CMML, and is a effective method for treatment of CMML.

OBJECTIVETo explore the better therapy for chronic tension-type headache (CTTH).

METHODSTwo hundred and eighty-eight cases were randomized into a sticking needling group (150 cases) and an acupuncture group (138 cases). In the sticking needling group, the manual sticking needling technique was adopted to stimulate the galea tendon-muscle node. In the acupuncture group, the conventional acupuncture therapy was applied to Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Taiyang (EX-HN 5), Touwei (ST 18), Hegu (LI 4), etc. The treatment was given once a day, and 30 days made one session. After two sessions of treatment and after three months follow-up, CTTH score (including the score of headache attack frequency and the score of headache severity) was observed and compared before and after treatment separately. The efficacy was evaluated in two groups.

RESULTSCTTH score was all reduced after treatment in the two groups (both P<0.01), the score in the sticking needling group was lower than that in the acupuncture group (2.38 +/- 1.22 vs 4.16 +/- 2.54, P < 0.01). The effective rate was 97.3% (146/150) in the sticking needling group, which was better than 88.4% (122/138) in the acupuncture group (P < 0.05).

CONCLUSIONThe manual sticking needling technique at galea tendon-muscle node achieves the superior results of reducing the pain attack frequency and severity of CTTH as compared with the acupuncture therapy of the routine acupoint selection.

OBJECTIVETo observe therapeutic effects of different acupuncture methods for recovery of mimetic function in the patient of spontaneous facial paralysis.

METHODSOne hundred and thirty-four cases of facial paralysis were randomly divided into a mimetic muscle acupuncture group (mimetic muscle group, n = 79) and a routine acupoint group (n = 55). The mimetic muscle group were treated by encircling needling frontal belly of epicranial muscle, orbicular muscle of eye, orbicular muscle of mouth and buccinator muscle, and the routine acupoint group with acupuncture at Dicang (ST 4), Jiache (ST 6), Yangbai (GB 14), Sibai (ST 2), Cuanzhu (BL 2), etc. on the affected side. Their therapeutic effects were compared after they were treated for 2 courses.

RESULTSThe effective rate and the good rate were 94.9% and 92.4% in the mimetic muscle group and 70.9% and 52.7% in the routine acupoint group, respectively, with a significant difference between the two groups (P < 0.05).

CONCLUSIONThe therapeutic effect of needling the mimetic muscle on spontaneous facial paralysis is superior to that of the routine acupuncture therapy.

OBJECTIVETo investigate the alkaloids from the stem of Artabotrys hainanensis.

METHODCompounds in plant extracts were separated by silica gel and sephadex LH-20 column chromatography. Chemical structures were elucidated by chemical and spectral analyses including UV, 1H-NMR, 13C-NMR, ESIMS and ESI-MS-MS.

RESULTEight alkaloids were isolated and identified as spinosine (1), 3-hydroxynornuciferine (2), juzirine (3), artabotrine (4), liridine (5), assimilobine (6), isococlaurine (7), N-demethylarmepavine (8).

CONCLUSIONAll alkaloids were isolated from this plant for the first time and compounds 1, 3, 7 and 8 were isolated from genus Artabotrys for the first time.

To study the effect of interleukin-15 (IL-15) on the proliferation, differentiation and apoptosis of MDS CD34(+) cells, CD34(+) cells of high enrichment were separated by MACS system, and cultured in liquid media with different concentration of IL-15 in treated group and without IL-15 in the control group. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and cell by FCM, and the other MDS CD34(+) cells were stained by cytochemical staining after culture. The results showed that after culture with IL-15 the proliferation and differentiation of MDS CD34(+) cells were obviously promoted. It was found the every lineage of mature cells developed, the expressions of cell surface antigens CD71, CD33 and CD19 all increased in the MDS CD34(+) cell treated with IL-15. It is suggested that IL-15 stimulates the proliferation and differentiation of MDS CD34(+) cells, and partly shows anti-apoptosis effects which may be applicable to the therapy MDS.

Objective To investigate children′s myelodysplastic hematopoietic cells reaction to interleukin (IL)-15.Methods CD 34 + cells in bone marrow from 18 myelodysplast syndrome(MDS) patients were purified by an immunomagnetic beads sorting system. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and flow cytometric analysis.Results On 8th cultured day,when IL-15 concentration was between 0-100 ng/ml,it could suppress apoptosis of hematopoietic cells in MDS patients in a dose-and- time dependent manner. IL-15 in study group significanthy lower than that of control group.Conclusion IL-15 may partly suppress apoptosis of hematopoietic cells in MDS patients.
