Traditional Chinese medicine(TCM) injection,which plays a unique role in the clinical treatment,is Chinese original dosage form.But in recent years due to its quality problems or unscientifically clinical use,some adverse reactions have reported,even several injections had serious adverse reactions.So how to develop TCM injection becomes one of the topics the public and scholars most concerned about.Therefore,the three "bottleneck" problems of TCM injection on the current development,which are the material basis and TCM theory,clinical efficacy and safety,and also quality control,were analyzed and discussed in the article.Then the countermeasures were proposed and provided ideas for future research and development of TCM injection.

Objective: To synthesize 10-position schiff base derivatives of emodin and study the anti-tumor activity. Methods:The 10-position schiff base derivatives of emodin were synthesized through emodin reacting with ammonia derivatives in absolute alcohol with acetic acid as the catalytic agent. Their structures were characterized by 1 H-NMR and ESI-MS, and the anti-tumor activity on k562 cells was determined by MTT method. Results:Three 10-position schiff base derivatives were synthesized and the structures were confirmed, and the IC50 on k562 cells was 4. 5, 3. 8 and 2. 0 μmol·L-1 , respectively. Conclusion:The 10-position schiff base de-rivatives of emodin can improve the anti-tumor activity and druggability of the parent compound, which are worthy of further study.

Objective To observe the effect of Huangqi Danshen Drop Pill(HDDP) on pituitary (Pit) induced acute myocardium ischemia. Methods Acute myocardium ischemia rat model was established by sublingual venous injection of Pit(0. 35U/kg). The changes of the T wave ( II channel ECG) and serum contents of lactate dehydrogenase (LDH), CK, superoxide dismutase (SOD) and malondialdehyde (MDA) were observed in various times after Pit injection. Results HDDP could significantly lower the height of T waves, increase SOD activity and decrease MDA content. Conclusion HDDP can improve acute myocardium ischemia induced by Pit.

Background and purpose:PTEN mutation has been found in 20%-40% of malignant gliomas.The common mutant epidermal growth factor receptor(EGFR vⅢ)was reported to coexpress in PTEN-deficient EGFR-expressing tumor.PTEN has been shown to interact directly with FAK and reduce its tyrosine phosphorylation levels to inhibit cell invasion.The invasion of glioma cells with EGFRvⅢ expression and PTEN deficiency is increased.This study was to observe whether PTEN inhibits glioma cell invasion even in the presence of strong pro-invasive signals provided by constitutive EGFR activity.Methods:U87?EGFR cells were transfected with pcDNA3.1 constructs encoding PTEN and the cells invasion levels were detected by transwell invasion assay.The expression of FAK was detected by immunoblotting.FAK expression vector was transfected into U87?EGFR-wtPTEN cells and the change of cells invasion was documented.Results:PTEN and PTEN(G129E)could inhibit cell invasion induced by EGFRvⅢ.PTEN and PTEN(G129E)could decrease the FAK phosphorylation at Tyr397.Over expression of FAK in U87?EGFR-PTEN abrogated PTEN-induced down-regulation of the phosphorylation status of FAK and rescued cell invasion.Conclusions:PTEN could inhibit cell invasion induced by EGFRvⅢ by dephosphorylating FAK.
