ABSTRACT
Objective: To analyze the curative effects of traditional Chinese herbal decoction on breast carcinoma patients in doxorubicin-induced cardiotoxicity by meta-analysis to provide evidences for doctors in treating breast carcinoma patients who were in doxorubicin-induced cardiotoxicity by traditional Chinese herbal decoction.Method: Published papers about the curative effects of traditional Chinese herbal decoction on doxorubicin-induced cardiotoxicity in breast carcinoma patients in clinical random control experiment were collected. To analyze the prescription rules and do metaanalysis in the eligible ones by the software RevMan5.2. Evaluate clinical effects of traditional Chinese medicine in treating breast carcinoma patients who were in doxorubicin-induced cardiotoxicity.Results: Ten references and 648 cases in total meeting eligibility criteria were included. Compared with pure anthracycline-based chemotherapy drugs, the breast carcinoma patients who received Anthracycline-based chemo therapy drugs with traditional Chinese medicine, their ECG changes less, their difference was statistically significant (OR=0.23, 95％ CI (0.16, 0.16), P ＜0.00001) . They had better cardiac function. the difference was statistically significant (OR=0.18, 95％ CI (0.09, 0.09), P ＜0.00001) . Their left ventricular systolic function improved. Their difference was statistically significant (MD = 3.82, 95％CI (0.29, 0.29), P=0.03 ＜ 0.05) . The myocardial enzyme spectrum, cardiac troponin I and myocardial troponin T were improved. Conclusion: To some extent, decoction of Chinese herbal medicine has effects on breast carcinoma patients with myocardial anthracycline-based drugs damage.
ABSTRACT
BACKGROUND:Studies have found that adipose-derived stem cells (ADSCs)/collagen complexes can promote the ADSCs differentiation and maturation into mature adipocytes and promote angiogenesis.OBJECTIVE:To explore the biological properties of the ADSCs/collagen sponge composite material and to detect its effect on angiogenesis.METHODS:(1) ADSCs were cultured on collagen sponge (experimental group) or cultured alone (control group).After 24 hours of culture,cell adhesive rate of ADSCs was determined with flow cytometry.After 2,4,6 days of culture,cell proliferation and level of vascular endothelial growth factor (VEGF) in the culture medium were detected.(2) Chick embryo chorioallantoic membranes were exposed and incubated for 7 days and then divided into four groups:0.2 mL of sterile PBS was added in the blank group,0.2 mL of 2× 108/L passage 3 ADSCs suspension was added in the ADSCs group,collagen sponge was added in the collagen sponge group,and collagen sponge with 0.2 mL of 2× 108/L passage 3 ADSCs suspension was added in the composite group.After 7 days of incubation,the microvessel count around the chorioallantoic membrane was measured.RESULTS AND CONCLUSION:(1) The cell adhesive rate of ADSCs to collagen sponge reached to (93.04±0.67)％.(2)The absorbance value (at 6 days of culture) and level of VEGF (at 4 and 6 days of culture) in the experimental group were significantly higher than those in the control group (P ＜ 0.01 or P ＜ 0.05).(3) Compared with the blank group,the number of microvessels was significantly higher in the ADSCs,collagen sponge and composite groups (P ＜ 0.05).Moreover,higher amount of microvessels were found in the composite group than the ADSCs and collagen sponge groups (P ＜ 0.05).To conclude,ADSCs can adhere well to the collagen sponge with good biocompatibility and their combined use can improve angiogenesis further by enhancing cell proliferation and VEGF secretion of ADSCs.
