With advances in complex network theory, the thinking and methods regarding complex systems have changed revolutionarily. Network biology and network pharmacology were built by applying network-based approaches in biomedical research. The cardiovascular system may be regarded as a complex network, and cardiovascular diseases may be taken as the damage of structure and function of the cardiovascular network. Although Chinese medicine (CM) is effective in treating cardiovascular diseases, its mechanisms are still unclear. With the guidance of complex network theory, network biology and network pharmacology, network-based approaches could be used in the study of CM in preventing and treating cardiovascular diseases. A new discipline-network cardiovasology of CM was, therefore, developed. In this paper, complex network theory, network biology and network pharmacology were introduced and the connotation of "disease-syndrome-formula-herb" was illustrated from the network angle. Network biology could be used to analyze cardiovascular diseases and syndromes and network pharmacology could be used to analyze CM formulas and herbs. The "network-network"-based approaches could provide a new view for elucidating the mechanisms of CM treatment.

Purpose: To study the expression of VEGF, VEGF-C, fit-4 in breast cancer and its relationship with lymph node metastasis and explore the significance of lymphangiogenesis on metastasis via lymphtics. Methods: Paraffin-embedded specimens from 82 patients with primary breast cancer who had undergone radical mastectomy with lymph node dissection were studied. VEGF, VEGF-C, flt-4 expression were investigated by immunohistochemical staining. Results: Positive staining for VEGF, VEGF-C, flt-4 were observed in some breast cancer cells. Furthermore, the expression of VEGF-C, flt-4 were significantly higher in lymph node-positive group than in node-negative group. Correlation was found within the expression of VEGF-C, flt4 also. Conclusions: Clinical significance was found between VEGF-C, flt-4 expression and lymph-node metastasis in breast cancer, and may be involved in the metastatic process.

0.05).CONCLUSIONS Levofloxacin 500mg orally administered is effective in the treatment of acute suppurative tonsillitis.

OBJECTIVE To study the effects of levofloxacin on QT correction dispersion(QTcd) interval in elderly patients hospitalized with acute exacerbations of COPD(AECOPD).METHODS Totally 124 patients received IV levofloxacin(500 mg qd) for 10-14 days.Evaluations included of 12-lead ECGs at baseline and blood examination before treatment,day 5 and after treatment.RESULTS QT correction(QTc) interval was no significant changes,but the QTcd interval was with significant prolongation.CONCLUSIONS IV levofloxacin could not cause QTc interval prolongation,but could make QTcd interval prolongation,which is a potential risk of arrhythmia in elderly patients with AECOPD.

Objective: To study the preventive actions of ganoderma lucidum polysaccharide(GLP) against kidney damage induced by cisplatin. Methods : Female Wistar rats were randomly divided into normal saline(NS) group, cisplatin(CDDP) group, GLP group, CDDP+GLP group. The changes of Scr, BUN, MDA, SOD were measured and renal structure was observed after 5 days by injecting drugs. Results : The contents of serum Scr and BUN of CDDP group were significantly highter than that of NS group. The activity of RBC SOD reduced and the contents of serum MDA increased. The contents of renocortical tissue MDA increased and the activity of SOD declined in renocortical tissue. The contents of serum Scr and BUN of GLP+CDDP group were significantly lower than that of CDDP group. The activity of RBC SOD increased and the contents of serum MDA declined. The concents of renocortical tissue MDA declined and the activity of SOD increased in renocortical tissue. The pathological slice indicated that renal structure was significantly improved. Conclusion : GLP may reduce cisplatin nephrotoxicity and its mechanism may be correlative with that GLP inhibited the blood and renocortical tissue lipid peroxidation increasing.

Objective To study the effects of russel viper venom X(RVV X)on blood coagulation protein.Methods We divide diluted protein into control and RVV-X groups,then use chromogenic substract assay to detect the activation effect of RVV-Ⅹ on coagulation factor Ⅶ,Ⅸ,Ⅹ and antithrombin,plasminogen,with or without activator.Results In RVV-Ⅹ group,the coagulation factor Ⅶ, Ⅸ and plasminogen displayed weakly enhanced chromogenesis,all P

[Objective] Antifungal action of fat-soluble extracts from Bulbus Allii Cepae (BAC) by different extraction technology on 16 strains of dermatophytes was observed to supply evidence for the optimization of extraction technology for BAC. [Methods] Four methods were used for the extraction of fat-soluble extract from BAC and the antifungal action of the extract was tested by medium dilution method. [Results] Fat-soluble extract freshly extracted from BAC by ether had a strong in-vitro antifungal action and its minimum inhibitory concentration (MIC) was not over 6.25 mL?L-1 against 10 strains of fungi including Shanghai Epidermophytom floccosum and its MIC against other strains ranged 12.5 -50.0 mL?L-1. The minimum fungicidal concentration of fat-soluble extract freshly extracted from BAC by ether was as the same as MIC. Fat-soluble extract freshly extracted by ether had no antifungal action after water removal by heating. [Conclusion] The extraction technology of freshly extracted by ether without heating is a better method for BAC and the fat-soluble extract extracted by this method has a better antifungal action.

Objective To evaluate the efficacy and safety of a levonorgestrel-releasing intrauterine system(LNG-IUS)for the treatment of dysmenorrhea associated with adenomyosis.Methods We recruited 48 women with moderate or severe dysmenorrhea associated with adenomyosis.All women were inserted of LNG-IUS into their uterine cavity from days 5-7 of their periods and maintained for 12 months.We compared the visual analogue scale(VAS)scores and verbal rating scale(VRS)scores of their dysmenorrhea and dyspareunia at baseline and 12 monthes follow-up.Results Forty-four women completed the study. There were significant differences between mean VAS and VRS scores changes of dysmenorrhea and dyspareunia at baseline and 12 monthes follow-up,those of dysmenorrhea dropping from 75?13 to 11?11 and 2.3?0.4 to 0.4?0.3,those of dyspareunia dropping from 54?19 to 4?4 and from 1.6?0.8 to 0.2?0.2 respectively.Overall 29 women(66%)were very satisfied or satisfied with the one-year treatment. Conclusion Insertion of LNG-IUS alleviates moderate or severe dysmenorrhea associated with adenomyosis remarkably.
