ABSTRACT
Objective To evaluate the tonic and health effects of Xuebijing injection,a traditional Chinese medicine injection,by means of corn low-nutritional mice model combined with benefit-damage index-general score (BDI-GS) evaluation system under a physiological dosage.Further,to investigate the scientific and practical benefits of the evaluation system in efficacy and safety re-evaluation of clinical traditional Chinese medicine injections.Methods Healthy ICR mice during growth period were randomly divided into blank control group and low,middle and high dose groups.All the mice were fed with corn diets,and treated by intraperitoneal injection once a day.The mice in the blank control group were injected with 0.4 ml 0.9％ sodium chloride injection,and the mice in the low,medium and high dose groups were injected with 0.2,0.4 and 0.6 ml Xuebijing injection,respectively,for seven days.On the 8th day,the mice were killed,dissected,and took nine kinds of organs including heart,lung,thymus,spleen,pancreas,kidney,gonad and femur.The weight BDI,index BDI and the corresponding weight BDI general score (GSw) and index BDI general score (GSI) were calculated,and the serum biochemical parameters were measured.Results Under the physiological dose,Xuebijing injection shows good safety of continuous infusion,tonic and health effects,and slight damages on the rest of organs.More specifically,the values of weight BDI and index BDI were all higher than 9.0,and values of GSw and GSI were all higher than the basic value of 9.0.Furthermore,these parameters increased in a dose-dependent manner.In addition,the total protein level of (47.6 ± 4.30) g/L in the high dose groups was significantly higher than (43.18 ± 2.60) g/L in the blank control group (P＜0.05).Conclusions The Xuebijing injection has a lower risk for conventional usage.This injection is safe under the physiological dosage and much safer in higher dosage designed in this study.The low-nutritional model combined with BDI-GS evaluation system can be used for re-evaluating the function and safety of clinical traditional Chinese medicine injections.

ABSTRACT
Objective This study aimed to investigate the protective effects of ademetionine 1,4-butanedisulfonate (SMT) against radiation injuries.Methods ICR mice were randomly divided into 7 groups,including normal control,irradiation-only,SMT administration-only,low-,medium-and high-dosages (250,500,1 000 mg·kg-1) of SMT pre-irradiation and high-dose of SMT post-irradiation in experimental groups.Blood and immunological experiments,organs index experiment and 30-day''s survival experiment were carried out to observe the protective effects of SMT on peripheral blood and immune system,organ index and the whole body injuries.Results Compared with irradiation-only group (4.23±1.16) ×109·L-1,the number of nucleated cells in bone marrow was (11.20±4.63) ×109·L-1 in the high dose of SMT pre-irradiation.The difference between two groups was significant.Compared with irradiation-only group (19.25±9.36),the colony forming unit-spleen was (39.00±7.57) in the high-dose SMT pre-irradiation group,there was a significant difference between the two groups.The index of liver,spleen,kidney and pancreas were significantly higher than those of the irradiation-only group in SMT administration groups.The survival rate of mice treated with SMT was increased,especially for the high dose group (46% lifted) when compared with irradiation-only group.Conclusion SMT can protect mice from radiation injuries.
ABSTRACT
Objective To explore the antitumor mechanism of xianhe yanling recipe( XHYLR ). Methods The mechanism of action of 241 compounds contained in the Chinese medicine, XHYLR was studied by using computational pharmacological. Methods including molecular docking,biotechnology network,chemical space technology and the prediction of absorption,distribution,metabolism,excretion and toxicity( ADME/T). Results Most of the compounds in XHYLR had good drug-like properties. Distribution of 241 compounds in chemical space also revealed that these compounds showed similar anti-tumor activity. It suggested that the prescription of XHYLR was reasonable. The phenomena that one molecular interacted with multiple target proteins and several molecules interact with one target protein were observed in XHYLR. For example,the COX-2 interacted with 40 micromolecules,and catechin interacted with five targets including COX-2. Conclusion These results are helpful for understanding the complicated mechanism of anti-tumor activity of XHYLR.
ABSTRACT
OBJECTIVE: To determine the contents of the related substances in Aosaibos crude drug by HPLC.METHODS: The determination was carried out on a SunFireTM RP C18 column with mobile phase consisted of phosphate buffer solution(pH 3.05)-acetonitrile(8∶2) at a flow rate of 1 mL?min-1.The detection wavelength was set at 220 nm;The sample size was 20 ?L and column temperature was set at room temperature.RESULTS: The main peak and the impurity peaks of 3 batchs of Aosaibos crude drug were well-separated.The contents of the related substances were all lower than 1.19%.CONCLUSION: The determination method is simple,sensitive and applicable for the content determination of the related substances of Aosaibos.
