In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

Applications of network pharmacology are increasingly widespread and methods abound in the field of drug development and pharmacological research. In this study, we choose rosiglitazone compound as the object to predict the targets and to discuss the mechanism based on three kinds of prediction methods of network pharmacology. Comparison of the prediction result has identified that the three kinds of prediction methods had their own characteristics: targets and pathways predicted were not in accordance with each other. However, the calcium signaling pathway could be predicted in the three kinds of methods, which associated with diabetes and cognitive impairment caused by diabetes by bioinformatics analysis. The above conclusion indicates that the calcium signaling pathway is important in signal pathway regulation of rosiglitazone compound, which provides a clue to further explain the mechanism of the compound and also provides a reference for the selection and application of methods of network pharmacology in the actual research.

OBJECTIVETo observe the effects of Tangshen Recipe (TR) on the homocysteine (Hcy) metabolism of patients with diabetic nephropathy.

METHODS64 patients with diabetic nephropathy were randomly assigned to two groups, 32 in each. Those in the Western medicine treatment group (Group A) received insulin and orally took anti-diabetic drugs, while those in the TR group (Group B) received insulin and orally took TR (consisting of astragalus, raw rehmannia root, sanchi root, euonymus branchlet, rhubarb, bitter orange, and dogwood fruit, etc. 4 g/package). Six months was taken as one therapeutic course. Another 48 healthy volunteers were recruited as the control group. Eight intermediate metabolites of the homocysteine metabolism in plasma were quantitated before treatment, three months and six months after treatment. The in vivo changes of each metabolite after treatment were analyzed.

RESULTSCompared with the healthy control group, contents of cysteine (Cys), Hcy, s-adenosylmethionine (SAM), and SAH significantly increased in Group A and B before treatment. Contents of methionine (Met), glutathione (GSH), and Cys-gly decreased significantly, showing statistical difference (P<0.05). Patients' in vivo contents of Cys, Hcy, SAM, and SAH significantly decreased, while contents of Met, GSH, and Cys-gly significantly increased after three and six months of treatment when compared with before treatment in the same group (all P<0.05). No statistical difference existed in contents of SAH, SAM, and GSH of Group A and B after six months of treatment when compared with the healthy control group (P>0.05). No adverse reaction occurred in Group A and B.

CONCLUSIONSTreatment of insulin and TR showed similar favorable effect to Western medicine in treatment of diabetic nephropathy. It could improve in vivo hypomethylation and oxidative stress.

OBJECTIVETo establish standard serum proteomic pattern for early liver cancer and explore its value in early liver cancer diagnosis.

METHODSThe serum samples were obtained from 12 healthy subjects and 12 patients with early liver cancer. After removal of serum albumin and IgG, 300 µg serum sample was mixed with the hydrating solution for two-dimensional gel electrophoresis. Each experiment was repeated for 3 times. With silver staining and image analysis, the differentially expressed proteins were identified to establish the standard proteomic pattern for early liver cancer. The proteomics pattern was then tested in the diagnosis of 13 cases of chronic liver disease and 10 healthy individuals in a double-blind manner.

RESULTSThirty-eight differentially expressed protein spots were identified. Eleven protein spots with differential expressions by over 5 folds were analyzed to establish the standard proteomics pattern for early liver cancer, which showed a sensitivity of 92% and specificity of 90% in early diagnosis of liver cancer.

CONCLUSIONThe standard serum 2-DE proteomic pattern for early liver cancer shows distinct differences from that of healthy subjects. The differentially expressed proteins and their specific combination pattern may have the potential for diagnosis and prognostic evaluation of early liver cancer.

AIMTo develop a method of identifying the existing of Panax notoginseng in products of traditional Chinese medicine compound Danshen.

METHODSTotal ion chromatograms (TIC) of Panax notoginseng, P. ginseng, and P. quinquefolius were obtained by means of LC/MS. Extracted ion chromatograms (EIC) posses m/z of 770, 800, 932, 946 and 1,108 of above-mentioned three herbs was compared between species. EIC 800 and 946 were selected as differentiation marks to distinguish P. notoginseng from the other two species. The EIC 800 and 946 of P. notoginseng were also compared to the EICs obtained by the same method from Chinese patent medicines of compound Danshen pellet, compound Danshen tablet, and compound Danshen injection. EIC 800 and 946 of P. notoginseng and its products possess similar peaks, relative retention time, and relative integral areas. Main chemical constitutes of P. notoginseng were also identified by using LC/MS/MS.

RESULTSEIC 800 and 946 were obviously different between P. notoginseng, P. ginseng, and P. quinquefolius. Patent medicines of compound Danshen pellet, compound Danshen tablet, which consist of extractions from P. notoginseng, possess the characteristic EICs. The selected EICs were stable and reproductive.

CONCLUSIONEIC 800 and 946, which correspond to ginsenoside Rg1, Re, and their isomers, can be used as identifying mark of P. notoginseng to differentiate it from other herbs, and also can be used to tell apart P. notoginseng from other herb extractions in Chinese patent medicines of compound Danshen.

BACKGROUND AND OBJECTIVEEpstein-Barr virus (EBV) has been detected in about 10% of gastric carcinomas. However, the pathogenetic role of EBV in gastric carcinoma is uncertain. This study was to explore the correlation of Fas/FasL expression to the apoptosis of tumor cells and tumor-infiltrating lymphocytes (TIL) in EBV-associated gastric carcinoma (EBVaGC).

METHODSFas/FasL expression in 49 specimens of EBVaGC, 20 specimens of EBV-negative gastric carcinoma (EBVnGC) and 12 specimens of normal gastric mucosa was detected by immunohistochemistry. The apoptotic index (AI) of cells was determined by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-biotin nick end labeling (TUNEL).

RESULTSThe positive rates of Fas were 91.7% in normal gastric mucosa and 76.8% in gastric carcinoma (P < 0.05); those of FasL were 16.7% in normal gastric mucosa and 58% in gastric carcinoma (P < 0.05). The positive rate of Fas was significantly lower in EBVaGC than in EBVnGC (71.4% vs. 90.0%, P < 0.05). The positive rate of FasL in EBVaGC was significantly higher than that in EBVnGC (63.2% vs. 45%, P < 0.05). The AI of EBVaGC cells was significantly lower than that of EBVnGC cells (P = 0.002). The number and AI of TIL in EBVaGC were higher than those in EBVnGC (P < 0.05). The AI of TIL was positively correlated with the level of FasL expression in tumor cells (r=0.237, P = 0.028).

CONCLUSIONUp-regulation of FasL expression and decrease of TIL apoptosis in EBVaGC may facilitate the escape of tumor cells from the host immunosurveillance, and it might contribute to the development and progression of carcinoma.
