Objectives To understand the social support levels among breast cancer patients in Yunnan, as well as to explore the factors associated with social support. Methods According to the unified inclusion and exclusion criteria,121 breast cancer in-patients with chemotherapy were interviewed with structured questionnaire. Social demographic characteristics, Xiao's Social Support Rating Scale,General Self-Efficacy Scale,clinical and experimental data were collected. SPSS version19.0 was used to analyze the frequency and the correlation between social support and influential variables were analyzed by using the chi-square test and non-parametric test. Results The levels of social support in total, objective social support, subjective social support and utilization degree for breast cancer patients were (49.43 ±5.69), (13.35 ±2.51), (27.59 ±3.78), (8.50 ±1.98) respectively. Marriage status and self-efficacy were associated with social support level significantly. The influencing factors such as age, education level, marital status, occupation, income, place of residence, religion, medical expenses payment type, self-efficacy were included in the univariate analysis. However, only marital status and self efficacy were positively correlated with social support (p<0.05) . Conclusions The breast cancer patients in Yunnan have a higher social support level overall. Having-marriage status and higher self-efficacy have a positive influence on breast cancer in patients' social support level.

This study is to investigate the anti-tumor activities of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) in vivo and in vitro, and its possible mechanism of action. The inhibitory effects of 9b on human hepatoma cell line HepG2, human breast carcinoma cell line MCF-7 and human myeloid leukemia cell line K562 were measured by MTT assay in vitro. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated H22 tumor was established. The results indicated that 9b could inhibit the proliferation of HepG2, MCF-7 and K562 cells in a dose and time dependent manner. The ICo50 values of 9b were 32.34 micromol.L-1 to HepG2 cells, 87.07 micromol.L-1 to MCF-7 cells and 149.10 micromol.L-1 to K562 cells after incubation for 48 h. The results of flow cytometry indicated that after being treated for 48 h with different concentrations of 9b, the ratios of HepG2, MCF-7 cells at the Go/G1 phase and K562 cells at the G0/Gl phase and G2/M phase increased significantly compared with control group, and the apoptotic rate increased with the increase of the concentration of 9b. 9b could significantly reduce tumor weight of H22 solid tumor mouse model in vivo. To summarize, 9b showed significantly anti-tumor activity in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.

GJ-4 is crocin enrichments extracted from Gardenia jasminoides J. Ellis, and our previous studies have shown that GJ-4 significantly improved learning and memory impairment induced by Aβ in mice. Herein, a memory deficit model was developed by injecting okadaic acid (OA) into the lateral ventricle of mice, and the neuroprotection and underlying mechanism of GJ-4 on neuronal injury caused by Tau hyperphosphorylation were investigated. The Animal Care & Welfare Committee, Institute of Materia Medica, CAMS & PUMC has approved all procedures (No.00000318). GJ-4 at different doses was intragastric administration to mice for 16 days. Step-down test and Morris water maze test showed that GJ-4 could significantly improve OA-induced memory impairment in mice, and reduced the loss of Nissl bodies in the hippocampus of mice. GJ-4 could also decrease the phosphorylation level of Tau protein at Ser396, Thr231 and Ser404 via increasing protein phosphatase 2A (PP2A) activity and inhibiting glycogen synthase kinase-3β (GSK-3β) activity. Besides, further researches indicated that GJ-4 could inhibit the level of oxidative stress in the brain of OA mice, reduce neuronal apoptosis and inhibit the neuroinflammation mediated by activation of astrocytes in the hippocampus of mice, and eventually achieve its effects in improving learning and memory impairment in mice. According to these findings, we anticipated that GJ-4 might be a potential therapeutic drug for Alzheimer's disease.

OBJECTIVETo investigate the electrophysiological effect of Xin' an granule (XAG) on ventricular muscle cell in ischemic rabbits.

METHODSA total of 48 rabbits were divided into the normal group and the ischemic group, and then subdivided into three groups, the control group, the high and low-dose XAG groups, 8 in each group. Rabbits in the low-dose XAG group and the high-dose XAG group were gastrogavaged XAG at the daily dose of 0. 85 g/kg and 3.40 g/kg, while the others in the control group were given the equal dosage of normal saline. All the rabbits were treated three times per day for successive 10 days. The rabbit model of ischemia was established by intravenous injected with 2. 5 U/kg posterior pituitary injection. Five minutes later, the monophasic action potential (MAP) and electrocardiogram (ECG) of each rabbit in the different groups were recorded and compared.

RESULTS(1) To normal rabbits, XAG could significantly shorten the action 50% and 90% potential duration (APD)50 and APD90 of ventricular muscle cell (P < 0.05 ), and high-dose of XAG could significantly increased the Vmax of MAP(P <0. 05). (2) While to ischemic rabbits, XAG could significantly prolong APD50 and APD90, and significantly increased the action potential amplitude (APA) and Vmax of MAP (P < 0. 05).

CONCLUSION(1) XAG can significantly shorten APD50 and APD90 of ventricular muscle cell, and high-dose XAG significantly increase the Vmax of MAP of normal rabbits. (2) XAG can delay and alleviate the manifestation characteristics of action potential of ventricular muscle cell during ischemia.

Objective To investigate the role of stromal cell derived factor-1α (SDF-1α)-laminin (LN) crosstalk in migration and differentiation of neural stem cells (NSCs).Methods Original generation of NSCs collected from 14-day pregnant fetal rats were separated and cultivated, and the phenotype characteristics were identified with immunofluorescence. The third generation of NSCs were collected, and they were divided into four groups: poly-L-lysine (PLL) group, PLL+SDF-1α group, LN group and LN+SDF-1α group. The NSCs in PLL and LN groups were inoculated into plates coated with 0.1 mg/mL PLL or 1 mg/mL LN, and the NSCs in PLL+SDF-1α and LN+SDF-1αgroups were inoculated into plates coated with PLL or LN and 1 mg/mL SDF-1α containing medium. The effect of SDF-1α-LN crosstalk on NSCs migrated numbers was determined by using Transwell cell migration test, and the differentiation of NSCs was determined by immunofluorescence staining.Results Primary NSCs were successfully isolated and cultivated, neurospheres formed at 3-5 days with typical NSCs morphology positively expressing Nestin which was the specific antigen of NSCs. Compared with PLL group, the number of NSCs migration in PLL+SDF-1α group showed no significant change (cells: 3.00±0.99 vs. 2.3±0.67,P > 0.05). Compared with LN group, the number of NSCs migration in LN+SDF-1α group was significantly increased (cells: 85.33±9.61 vs. 31.67±5.86,P < 0.05). Immunofluorescence staining showed that the differentiation rates of PLL and PLL+SDF-1α groups were almost zero, and some early differentiation neurons were detected in LN group with the differentiation rates of (12.50±2.56)%. The differentiation of early neuronal cells was significantly increased after SDF-1α-LN crosstalk, the neuronal differentiation rate was (21.40±3.41)%, and it was significantly higher than that of LN group (P < 0.05).Conclusion SDF-1α crosstalk with LN in extracellular matrix can significantly and synergistically enhance the migration and differentiation of NSCs in vitro.
