To study relevant risk factors of Shenmai injection induced adverse reactions by using Logistic model and ROC curve, and made the prediction for the occurrence of relevant adverse reactions/events. Case data of patients treated with Shenmai injection were collected by using the prospective, multi-center, large-sample, nested-case control method, in order to analyze the risk factors of Shenmai injection-induced adverse reactions/events, establish the logistic model and draw the receiver operating characteristic (ROC) curve for risk factors. During the study, 7632 patients (including 3 477 males and 4 155 females) were included, and eight of them suffered adverse reactions/events. Based on a multi-factor Logistic model analysis, the age (> or = 50 years) (OR = 5.061, 95% CI: 2.197-7.924; P = 0.001), the total number of medication days (OR = -1.020, 95% CI: -l.652 - 0.388; P = 0.002) and the single dose (OR = 0.245, 95% CI: 0.127-0.364; P = 0.000) were significant independent risk factors for Shenmai injection-induced adverse reactions/events. According to the results, ROC curves were drawn with age (> or = 50 years), the total number of days of inedication and single dose; The area under ROC curves the joint predictor (0.9753, 95% CI: 0.9443-1.000, P < 0.005) was larger than that of the other three single indexes, with a higher risk prediction value. The independent risk factors for Shenmai injection-induced adverse reactions/events included the age (> or = 50 years), the total number of days of medication and single dose. In clinical practice, the age (> or = 50 years), the total number of days of medication and the medication dose can be substituted in the joint predictor calculation formula (P = 1 / [1 + e(-(-21.58 + 5.061 x Xage - 1.020 x Xd + 0.245 x X(mL)] to predict the potential adverse reactions of patients and adjust the dosage regimen.

OBJECTIVETo investigate the biological effects of ectopic overexpression of glial fibrillary acidic protein (GFAP) in human malignant glioma cell line, and to explore new method of differentiation induction gene therapy for gliomas.
METHODSA eukaryotic expression vector containing 1.1 kb GFAP cDNA fused with green fluorescent protein (GFP) gene, pIRGFP-GFAP, was transfected into human SHG-44 glioma cell line by lipofectamine. The expression of GFAP/GFP gene and their proteins were detected by fluorescent real-time monitoring, in situ hybridization, Western blot and immunocytochemistry. Flow cytometry, soft agar colony formation and other methods were used to measure the effects of exogenous GFAP expression on cell cycle progression, morphology and growth features of the transfected glioma cells.
RESULTSThe expressions of GFAP mRNA and its protein were markedly increased in SHG-44 cells upon stable transfection with pIRGFP/GFAP vector. Profound morphological changes in these cells were also observed, including the formation of abundant, stellate and thin cytoplasmic processes and a reduction of atypia. Cell proliferation rate and its tumorigenecity on soft agar were markedly reduced. In addition, cell cycle analysis revealed a percentage decrease of cell populations at G0/G1 and G2/M phases.
CONCLUSIONSEctopic overexpression of GFAP gene could significantly suppress the growth of SHG-44 malignant glioma cells along with an induction of differentiation. These results imply that forced over-expression of GFAP gene may provide a new strategy for glioma therapy.

OBJECTIVETo investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.
METHODSA total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.
RESULTSShort-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.
CONCLUSIONSInonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.

OBJECTIVETo compare the tubulogenesis capability of malignant glioma-derived microvessel endothelial cells (GDMEC) from human brain with that of ECV304 cells in a three dimentional model and to explore the significance of GDMEC in the study on angiogenesis.
METHODSThe GDMEC were isolated from malignant gliomas of human brain and purified by selective binding to the monoclonal antibody against CD105 bound to the magnetic MACS MicroBeads. GDMEC and endothelial-like cell line ECV304 were compared with their capabilities of formatting tubule-like structure (TLS) in the three dimentional collagen matrix, with or without inducement by various concentration of vascular endothelial growth factor (VEGF).
RESULTSThe obtained GDMEC had a high purification (98%) and could be successfully cultured in vitro. GDMECs formed more TLS than ECV304 cells of the same number and at the same time points. VEGF could induce rapid formation of TLS in a dose-dependent manner, however, ECV304 cells were less response to VEGF stimulation.
CONCLUSIONSGDMEC could maintain their endothelial characteristics and potential capability of angiogenesis. They were more response to VEGF than ECV304, therefore, more suitable for in vitro studies on tumor angiogenesis.
