BACKGROUND:At present,application revascularization and drug treatment may arrest aggravation of heart function and arrhythmic development,but effectiveness is limited.Infarcted myocardial cells are still impossible to regenerate.How to make necrotic myocardial cell regeneration and diastolic myocardial function is the problem to solve.OBJECTIVE:To analyze the study progress of bone marrow stem cells in treatment of myocardial infarction.RETRIEVAL STRATEGY:A computerized online database of Pubmed was searched to identify articles published from May 2000 to July 2006 with the key words of "the marrow stem-cell,cell transplant,myocardial infarction" in English.Simultaneously,articles published between October 1997 and December 2006 were identified in China Journal Full-text Database with the same key word in Chinese.Sixty-seven articles were retrieved and data were selected primarily.Inclusive criteria:①articles related to the transplantation of bone marrow stem cells for the treatment of myocardial infarction,②in the same field,articles recently published or in authoritative journals.Exclusive criteria:①articles of repetitive study,and ②Meta analysis.LITERATURE EVALUATION:Articles mainly analyzes the transplantation of stem cells for the treatment of myocardial infarction.Of the 30 included articles,10 were reviews and the rest was clinical or basic studies.DATA SYNTHESIS:①Bone marrow stem cells are composed of bone marrow mononuclear cells,hematopoietic stem cells,bone marrow mesenchymal stem cells,endothelial stem/progenitor cells,multipotent adult progenitor cells and so on.②After the transplantation,bone marrow stem cells can differentiate into myocardiocytes,and do effectively electromechanical coupling with receptors.Bone marrow stem cells can promote the angiogenesis in ischemic region,avoid ethical dispute and immunological rejection,and these cells are easy to collect.Bone marrow stem cells are adult stem cells,and its transdifferentiation deserves further study.Many clinical studies showed that autogeneic bone marrow stem cell transplantation for the treatment of acute myocardial infarction and heart failure could be achieved.③Matrix metalloproteinase,stem cell factor and stromal cell chemokine from bone marrow stem cells play important roles in stem cell mobilization,homing and myocardial repair.Tissue injury and high-level multipotential stem cells are two key factors of the differentiation of bone marrow stem cells in myocardial microenvironment.④ Problems in bone marrow stem cell transplantation included cell type,regulatory mechanism of transdifferentiation,optimal time,manner and safety of transplantation,etc.CONCLUSION:Through establishing complete animal model,the possibility of each technique in clinical procedures is explored.Bone marrow stem cells in treatment of acute myocardial infarction may become a new method,which has different from traditional drug treatment,interventional therapy of cardiovascular disease and surgical intervention.

Objective To screen the anti-tumor prescription (Shengzao Fang) of Shengma (Rhizoma Cimicifugae) combined with Zao Jiao-ci (Spina Gleditsiae), and evaluate its anti-tumor effects. Methods The lung metastatic model of 4T1 breast cancer and the 4T1 subcutaneous transplanted model were established, both models of mice were randomly divided into model group, Shengma group, Zao Jiao-ci group, Shengzao Fang first group, Shengzao Fang second group and Shengzao Fang third group, 10 mice for each group. The proportion of Shengzao Fang was ascertained by their anti-tumor effects. MTT assay was used to investigate the effects of Shengzao Fang on 4T1 breast cancer. The concentration of type 1 collagen (Col-Ⅰ), platelet-activating factor (PAF), tissue inhibitor of metalloproteinase 1 (TIMP-1), tyrosine kinase receptor A (TrkA) and tyrosine kinase receptor B (TrkB) in serum from tumor-bearing mice was tested by enzyme-linked immunosorbent assay (ELISA). The effects of Shengzao Fang on matrix metalloproteinase (MMPs) was examined by Gelatin matrix method. Results Compared with the model group, the prescription of Shengma∶Zao Jiao-Ci=2∶1 significantly suppressed lung metastasis of 4T1 breast cancer, showing fewer lung nodes, lower lung metastasis rate and highest tumor inhibitory rate to 4T1 subcutaneous transplanted model. Although the concentration of serum Col-Ⅰ, PAF, TIMP-1, TrkA and TrkB was decreased in all treated group, the prescription of Shengma∶Zao Jiao-ci=2∶1 had the strongest activity, and its inhibitory effect on the expression of MMP-2 and MMP-9 was strongest, too. Conclusion The prescriptions of Shengma combined with Zao Jiao-ci had different antitumor activity, the strongest activity was exhibited when shengma∶Zao Jiao-ci was 2∶1, suggesting that 2∶1 was optimization for Shengma combined with Zao Jiao-ci.

Objective To study the effect of cold prolonged storage of rat livers with self-designed HYS solution on hepatic biochemical functions.Methods The preservation effect of HYD solution with that of UW solution and Lactate Ringer's solution(LR)was compared by using isolated perfused rat liver model.Results All the indices of hepatic biochemical functions in HYD group were better than in LR group for 12 h storage.The contents of ATP,TAN and AEC in HYD group were significantly higher than in Uw group for 36 h storage(P＜0.05).pH in HYD group was markedly higher than in UW group for 30 or 36 h storage(P＜0.05).The hydrolytic activities of H+-ATP ase in hepatic mitochondria and bile production were mildly higher in HYD group than in UW group(P＞0.05).No significant difference in AST,ALT and LDH in the effluent were found between HYD group and UW group(P＞0.05).Conclusions The effect of 12 h storage of rat livers with HYD solution might be better than with LR solution.The effect of HYD solution is similar to that of UW solution within 36 h storage.However.HYD solution is slightly superior to UW solution in some aspects.such aS improvement of energy metabolism during cold storage and reperfusion,prevention of intracellular acidosis.bile production and perfusion of liver in situ.

Objective To investigate the change of matrix metalloproteinase 3(MMP-3), matrix metalloproteinase 9 (MMP-9) and tissue inhibitors of metalloproteinase 1 (TIMP 1) in arterial plasma and their effects on post-stenting restenosis in the patients with acute coronary syndrome(ACS). Methods MMP-3, MMP-9 and TIMP-1 in arterial plasma were detected by enzyme-linked immunosorbent assay (ELISA) in 132 patients with ACS. The 132 patients were divided into two groups: restenosis group (n = 21) and non-restenosis group (n = 111), while 50 persons were as a normal control group. Results The levels of MMP-3[(15.99±4.30) vs. (4.86±2.98) ng/L, P=0.022] and MMP-9 [( 1.41±3.06) vs. (3.79±1.46) ng/L, P=0.041] in arterial plasma were higher in ACS group than in the control group. And the level of TIMP-1 tended to increase. The levels of MMP-3 and MMP-9 in arterial plasma were higher after stenting than before stenting. It reached a peak in the first 48 hours, and was still significantly increased in one week. The level of TIMP-1 was similar, but it reached the peak slowly. Before stenting, the level of MMP-9 was higher in restenosis group than in non-restenosis group [( 17.94±6.44) vs. (9.93±2.19) ng/L, P =0.003], but there were no differences between the two groups in the levels of TIMP-1 and MMP-3. During follow-up, the levels of MMP-3[(21.66±2.72) vs. (14.27±1.28) ng/L, P=0.033] and MMP-9[(22.81±5.31) vs. (12.10±2.76) ng/L, P = 0.039] were higher in the restenosis group than in the non restenosis group, but there was no difference between the two groups in the level of TIMP-1. Conclusions The increase of MMP-3 and MMP-9 in arterial plasma may contribute to the pathophysiological progress after stenting in patients with ACS, which may be a prediction for restenosis.
