OBJECTIVETo study the inhibitory effect of wogonin on the growth and proliferation of breast cancer cells MDA-MB-23, and observe its effect on the adhesion, migration and invasion of MDA-MB-23 cells, in order to further study its molecular mechanism.

METHODMTT assay was used to detect the effect of wogonin on MDA-MB-23 cell growth. Ki-67 assay was adopted to test the effect of wogonin on cell proliferation. Scratch test, adherence test and invasion chamber assay were taken to detect the effect on the migration and invasion abilities of MDA-MB-231 cells. Proliferation and metastasis-related proteins and relevant signaling pathways were detected by Western blotting.

RESULTWogonin could remarkably inhibit the growth and proliferation of MDA-MB-231 cells, significantly inhibit migration, adhesion and invasion abilities of breast cancer cells at a low concentration, and effectively inhibit the expression of Survivin, Bcl-2, ICAM-1, MMP-2, MMP-9 proteins of MDA-MB-231 cells.

CONCLUSIONWogonin could notably inhibit growth and proliferation of breast cancer cells, and inhibit migration, adhesion and invasion of MDA-MB-231 cells. Its invasive and adhesive effects on MDA-MB-231 cells may be related to the decrease in ICAM-1, MMP-2, MMP-9 expressions.

Penile erection hardness is one of the key factors for successful sexual intercourse, as well as an important index in the diagnosis and treatment of erectile dysfunction (ED). This article gives an overview on the component and impact factors of erection hardness, summarizes some commonly used evaluation methods, including those for objective indexes, such as Rigiscan, axial buckling test and color Doppler ultrasonography, and those for subjective indexes of ED patients, such as IIEF, the Erectile Function Domain of IIEF (IIEF-EF), and Erection Hardness Score (EHS), and discusses the characteristics of these methods.

Monoclonal antibodies (MoAbs) have different mechanism and adverse effects compared with cytotoxic agents. The introduction of MoAbs has improved the treatment potency to malignant lymphoma without decreasing the quality of life. However, there are many questions to be answered: What is the profound mechanism of MoAbs? How about their long-term adverse effects? What is the best medication pattern in different disease types?

This retrospective analysis compared standard regimen of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with the dose-dense ABVD regimen (ABVD-21) in terms of efficacy and toxicity. Patients who had early-stage unfavorable or advanced Hodgkin's lymphoma (HL) according to German Hodgkin Study Group criteria from March 1999 to February 2011 were analyzed for treatment response, long-term survival and hematological toxicity. There were 85 patients in the ABVD-21 group and 118 patients in the ABVD group respectively. The complete remission rates after completion of treatment were 92.9% and 90.7% for ABVD-21 and ABVD, respectively. During a median follow-up period of 62 months, no significant difference was found in projected 10-year progression-free survival (PFS) and overall survival (OS) rates (84.7% and 94.1% respectively for ABVD-21; 81.4% and 91.5% for ABVD). Subgroup analyses showed that ABVD-21 was significantly better than ABVD for patients with IPS≥3 in terms of PFS and OS rates. Grade 3 to 4 leukopenia (51.8% vs. 28.8%, P=0.001) and neutropenia (57.6% vs. 39.0%, P=0.009) were more common with ABVD-21. We were led to conclude that dose-dense ABVD did not result in better tumor control and overall survival than did ABVD for early-stage unfavorable HL. However, patients at high risk, for example, with IPS≥3, may benefit from dose-dense ABVD.

In this paper, based on the special influence of supramolecular chemistry on the basic theory of Chinese medicines ( CM) , the authors further analyzed the history of meridian tropism and natural origins of CM organisms and explained CM ingredients and the universal regularity of the automatic action of the supramolecular "imprinting templates" hole channel structure. After entering human bodies, CMs, as the aggregation of supramolecular "imprinting templates" , automatically seek supramolecular subjects that are matched with their "imprinting templates" in human meridians and organs for the purpose of self-recognition, self-organization, self-assembly and self-replication, so as to generate specific efficacy in meridians and organs, which is reflected as the meridian tropism phenomena at macro level. This regularity can be studied by in vitro and in vivo experimental studies. In vitro methods are mostly supra molecular structure analysis and kinetic and thermodynamic parameter calculation; Whereas in vivo methods are dominated by the analysis on object component distribution, chromatopharmacodynamic parameters and network chromatopharmacodynamic parameters; Particularly, the acupoint-medicine method can simplify to study the supramolecular subject-object relations. Consequently, CM's'meridian tropism reveals the universal regularity for interactions of macromolecular and micromolecular "imprinting templates" of subjects and objects in natural organisms. As the first barrier for the material base of the CM theory and breakthrough in the modernization of the basic CM theory, meridian tropism plays an important role in studies on basic theories of the basic CM theory.
