Shengmai Injection (SMI), is a traditional Chinese medicine (TCM) formula injection composed of Panax ginseng, Ophiopogon japonicas and Schisandra chinensis, which is widely used in clinic for the treatment of cardiovascular diseases as well as protecting against pulmonary disease and add-on therapy to cancer chemotherapy. In recent years, the pre-clinical basic research of SMI was widely performed. The studies, including chemical composition, in vivo process, and action mechanism and so on of SMI, helped to provide scientific foundation for revealing the material basis of formula. In this paper, the studies on material composition, pre-clinical pharmacokinetics and pharmacodynamics of this formula were summarized, so as to provide reference for the quality control, second development and rational clinical application of SMI.

Universities are cradles of leadership and full-developed specific professional.Besides specific courses,reasonable sexual health education should be set up to make the students succeed when they grow up.

Objective To lay the physiological and biochemical basis for establishing and evaluating tree shrews model of human disease. Methods There were 92 Tupaia belangeri chinensis, in which half of them were male,they were allowed to eat nothing for 12 hours, then we sampled heart blood 0.8~1.0 mL without anesthesia and put blood samples into sterilized centrifuge tube for separation and preparation of serum. Olympus AU5400 automatic biochemistry analyzer was used to measure biochemical indexes. Then 1.5~2.0 mL of urine of each tree shrew was collected and put into sterilized centrifuge tube for measuring renal function by using Combi-scan500 urine analyzer. Fianally SPSS statistics software was used to analyse the measured values, and comapared the measured values with the human reference values. Results There were significant differences in myocardial enzymes and some renal function indexes such as lactic dehydrogenase,α- hydroxybutyric, acid dehydrogenase, creatinine, uric acid, urine specific gravity and pH value between male and female Tupaia belangeri chinensis ( <0.05), and there was no significant difference in the rest of the measured values ( >0.05) . Then determination value of Tupaia belangeri chinensis, male’s and female’s, myocardial enzyme and part of the renal function indexes were compared with the human reference values. Some indexes including urea, urine specific gravity, urine, urobilinogen were in the range of human reference value, while the values of urine bilirubin, urine nitrite. lactate dehydrogenase, creatine kinase, α-hydroxybutyrate dehydrogenase, creatine kinase isoenzyme CKMB were higher than the human reference value. White blood cell, urine protein, ketone, occult blood most of them were negative as the same to human reference value, but sometimes were positive, and the positive rates respectively were 3.95%and 46.1%,39.5%,2.63%. The measured value of Vitamin C was positive that is completely opposite to human reference value, but sometimes is negative, the negative rate was 6.6%. Conclusion Urea, urine specific gravity, urine, urobilinogen, urine bilirubin, urine nitrite can be directly used as the indexes for evaluating tree shrews models of human disease, other indexes can be used as indexes for judgment of the normal physiological and biochemical basis of tree shrews.

The M and NP genes of H5N1 avian influenza virus (A/chicken/Hubei/489/2004) were amplified by RT-PCR from viral RNA,and cloned into pMD 18-T vector respectively.The expression plasmid containing the M gene (pHM6-m) or the NP gene (pHM6-np) was then constructed by inserting the M or NP gene into the pHM6 eukaryote expression vector; the constructed plasmid was then sequenced.32 BALB/c mice (6-week-old) were divided into four groups at random.Three groups of BALB/c mice were inoculated one time the intramuscular route with either 30 μg of plasmid pHM6-m,30 μg of plasmid pHM6-np or the mixture of plasmid pHM6-m (15 μg ) and pHM6-np(15 μg) respectively.A additional group of mice were injected with 100 μ1 PBS as controls.Two weeks later,all mice were challenged with homologous H5N1 avian influenza virus,and observed in the following 12 days.The survival rates of mice in the pHM6-m group,the pHM6-np group and mixed plasmids group were 62.5% ,25.0% and 50.0%,respectively.Results showed that effective protection could be provided by either pHM6-m or pHM6-np,but pHM6-m provided a better protective effect than pHM6-np.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.
