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.

Objective To investigate the potential application of targeting at vascular endothelial growh factor (VEGF) induced apoptosis in leukemic cell lines by combined use of Bevacizumab and chemotherapeutic drug. Methods Leukemic cells were treated with several drugs at different concentrations in culture. The effect of VEGF, Bevacizumab and co-treated with Ara-C on leukemic cells proliferation were evaluated by CCK-8 and apoptosis and cell cycle were detected by flow cytometry (FCM). Results VEGF could enhance the proliferation of leukemic cells and caused a dose-dependent manner on U937 cell. It also increased the percentage of cells in S phase, tested by, and Bevacizumab group was decreased. Apoptotic rate of cells treated with Bevacizumab or co-treated with Bevacizumab and Ara-C for 48 h were significantly higher when compared with control or Ara-C group, respectively (P<0.05), but the apoptotic rate of VEGF group or VEGF and Ara-C group was lower (P>0.05). There was no significant difference in apoptotic rate between control and combined use of VEGF, Bevacizumab and Ara-C group(P>0.05). Conclusion VEGF could enhance the proliferation of some leukemic cells, and may contribute to leukemic cells survival and a resultant resistance to chemotherapy-triggered cell death. The study also showed that leukemic cells growth was significantly inhibited by Bevacizumab through directly against VEGF, and the sensitivity of leukemic cells for chemotherapeutic drug was increased.

Objective To clarify the effectiveness of QS Nd ∶ YAG laser on melasma in Chinese patients.Methods A group (n=45) of patients previously diagnosed as facial melasma were treated with QS Nd ∶ YAG laser at approximately 1 week intervals.Eleven to twenty treatments were per formed for each patient.The treatment efficacy of QS Nd ∶ YAG laser was evaluated by patients and doctors,respectively,at various time point such as before treatment,5 weeks and 10 weeks after treatment and end of the treatment.The skin melanin index and the transepidermal water loss were e valuated by the skin multifunction tester at different time point,respectively.Results Compared with untreated,the melanin index of melasma areas decreased significantly after the laser treatment for 5 weeks,10 weeks and the end of treatment.But there was no significant difference in the melanin index of normal skin areas with or without laser treatment.Compared with untreated,the transpidermal water loss of melasma areas increased significantly after the laser treatment for 5 weeks,10 weeks and end of treatment.The patients' skin became smooth,delicate,pores shrink and more flexible.In 45 melasma patients treated by QS Nd ∶ YAG laser,8 cases basically cured (17.78 ％),25 cases were markedly effective (55.56 ％),12 cases improved (24.44 ％) and only 1 case was uneffective (2.22 ％).Theoverall effective rate was 73.33 ％.Conclnsions QSNd∶ YAG laser is a useful treatment modality for Chinese women who have melasma with precise efficacy,less side effects and high safety.

Objective To determine the effect of nanochemotherapy drug on Survivin and p53 ex-pressed by human biliary traet carcinoma cell line QBC939.Methods Culturing the human biliary tract carcinoma cell line QBC939 in vitro and it was divided into five groups including saline,nanochemotherapy drug,nanopartiele withoul nanochemotherapy drug,5-FU and gemcitabine.Using the methods of MTT and flow cytometry to observe the growth of QBC939 which was dealt with different drugs.In addition,RT-PCR and Western blot were used to delect the expression of mRNA and protein by Survivin or p53.Results The expression of mRNA and protein by Survivin decreased in the following set:saline,nanoparlicle withoul nanochemotherapy drug,5-FU,gemcitabine and nanochemotherapy drug,respeclively.However,the ex-pression of mRNA and protein by p53 were in reverse order.The inhibiting action to QBC939 was obvious in nanochenmtherapy drng and the apoplotic rate was higher than others except for gemcitabine(P＜0.05). Conclusion Nanochemotherapy drug has significant effect on treatment cholangiocarcinoma in vilro,which may attribute to the down regulation of Survivin and up regulation of p53.

Objective: Our purpose was to explore the change regularity of β-glucuronidase (β-G) in body of patients with Non-Hodgkin malignant lymphoma. Methods: β-G was examined synchronously both in the serum and in the tumor tissue of 13 cases patient with Non-Hodgkin malignant lymphoma by using the method of enzymlinked immunsorbent assay (ELISA) and immunohistochemistry separately. Among them, 3 cases were studied by using the immuno electron microscopic technique. Results: β-G was highly expressed both in the serum and tumorous tissue in patients with non-Hodgkin malignant lymphoma and there was obviously difference as compared with the control group (P<0.01). Conclusion: The combined detection with functional and morphological methods to β-G, it may be assistant target to early discovery and early diagnosis of Non-Hodskin malignant lymphoma.

Objective To explore the feasibility of making cystoscope training model with rapid prototyping technology and its training method in cystoscope operation. Methods Constructed a cystoscope training model, and designed a set of corresponding training methods ac-cording to the process and behavioral essentials of cystoscope operation. Selected 20 students who have never learned cystoscope operation and trained them with the new designed cystoscope training mode and training methods, and the training results were verified.
