Objective To investigate the effect of Shengxue-zengbai Decoction on the expression of ICAM-1 and SCF in bone marrow tissue and on the mechanism of hematopoietic reconstitution in bone marrow transplantation (BMT). Methods The experimental animals were randomly divided into S groups: normal group received no treatment, BMT control group, G-CSF group, Shengxue group, and Shengxue +G-CSF group. BMT mouse models were established. Shengxue group, Shengxue + G-CSF group were given Shengxuezengbai Decoction. On days 9, 14, 24 after BMT, mice were killed and peripheral blood cells, bone marrow nucleated cells were detected. Histological observation of bone was made and the ICAM-1 and SCF expression were assayed by immunohistochemistry. Results In Shengxue-zengbai Decoction group, the peripheral blood cell, bone marrow nucleated cell on the days 9, 14, 24 after BMT were higher than the other control groups. The expression of ICAM-1 and SCF than in the other control groups (P<0.05 or P<0.01 > . Conclusion Shengxue-zengbai Decoction enhances ICAM-1 and SCF expression in bone marrow after syngenic bone marrow transplantation in mice, which may be related to the mechanisms of its accelerating hematopoietic reconstitution in allogenic bone marrow transplantation.

AIM: To study the pharmacokinetics of magnesium isoglycyrrhizinate (MgIG),which was diluted by 5%glucose injection in a total volume of 250 mL, after a single and multiple intravenous dose in 10 healthy volunteers. METHODS: MgIG 100 mg once daily for 9 d in the multiple-dose regiment. Plasma MgIG concentrations are measured using high performance liquid chromatography (HPLC). Waters HPLC instrument was used with the Hypersil ODS2 C18 (5 μm, 300 mm×4.6 mm) column. The mobile phase was composed of 0.23 mol·L-1 phosphate buffer (pH=7.4):acetonitrile (79∶21).Flow rate was 1.0 mL·min-1 and column temperature was maintained at 40°C. The UV detector was set at 250 nm. The concentration time curves of MgIG were fitted to a two-compartment open model.

Objective To investigate clinicopathological features of scalp angiosarcoma, and to analyze the relationship of tumor stage and treatment with prognosis. Methods Clinical and follow-up data were collected from 16 patients with non-metastatic primary scalp angiosarcoma treated in the Department of Plastic and Reconstructive Surgery of Zhongda Hospital, Southeast University from September 2002 to June 2013. According to the seventh edition American Joint Committee on Cancer (AJCC)TNM staging system for soft tissue sarcomas (2010), staging of scalp angiosarcoma was performed for the 16 patients. Statistical analysis was carried out by the Kaplan-Meier method for survival rates and by the Log-rank test for survival curve. The Cox regression model was used for multivariate regression analysis. Results Of the 16 patients, 4 had stageⅠangiosarcoma, 4 stage Ⅱangiosarcoma, and 8 stage Ⅲ angiosarcoma. The tumor usually began as ecchymosis-like lesions on the head or face in early stage, and progressed into dark red infiltrative plaques, nodules and ulcers which easily ruptured and bled in later stage. Histopathological examination showed generalized vascular proliferation and infiltration with high histological morphological diversity. Cytologic atypia was commonly seen. The median time to recurrence was 15 months, and local recurrence occurred in 7 patients. The median time to metastasis was 20.5 months, and distant metastasis was observed in 8 cases, including 4 cases of pulmonary metastasis, 2 lymph node metastasis, 1 liver metastasis and 1 bone metastasis. The survival time was 33.0 ± 4.4 months (median, 32 months)in 4 patients with stage Ⅰangiosarcoma, 24.0 ± 7.9 months(median, 15 months)in 4 patients with stage Ⅱangiosarcoma, and 23.9 ± 3.9 months (median, 24 months)in 8 patients with stage Ⅲ angiosarcoma. Additionally, the survival time was 23.4 ± 5.2 months(median, 21 months), 24.4 ± 5.7 months(median, 24 months)and 35.8 ± 9.7 months(median, 26 months) in 5 patients receiving surgical treatment alone, 7 patients receiving surgical treatment and radiotherapy, and 4 patients receiving surgical treatment, radiotherapy and immunotherapy, respectively. Conclusions Surgical treatment combined with radiotherapy and immunotherapy may serve as the first-choice treatment for scalp angiosarcoma. Tumor size and treatment regimens are main factors influencing prognosis of scalp angiosarcoma.
