ABSTRACT

At present, the issues regarding multi-center clinical trials of new drugs of traditional Chinese medicine(TCM) remain: the lack of agreement on the content and scope of the ethical review among the ethics committee members of the center and the participating units results in repeated review, which leads to a time-consuming ethical review process. Moreover, the review capabilities of the ethics committees of various research centers are uneven, which is not necessarily beneficial to the protection of subjects' rights and safety. In view of the existing problems, to improve the efficiency of ethical review of multi-center clinical trials of new drugs of TCM and avoid repeated reviews, the TCM Clinical Evaluation Professional Committee of Chinese Pharmaceutical Association organized experts to formulate the "Consensus on collaborative ethical review of multi-center clinical trials of new drugs of TCM(version 1.0)"(hereinafter referred to as "Consensus"). The "Consensus" is formulated in accordance with the requirements of relevant documents such as but not limited to "the opinions on deepening the reform of the evaluation and approval system to encourage the innovation of pharmaceutical medical devices", "the regulations of ethical review of biomedical research involving human subjects". The "Consensus" covers the scope of application, formulation principles, conditions for the ethics committee of the center, sharing of ethical review resources, scope and procedure of collaborative review, rights and obligations, etc. The aims of the "Consensus" is to preliminarily explore and establish a scientific and operable ethical review procedure. Additionally, on the basis of fully protecting the rights and interests of the subjects, a collaborative ethical review agreement needs to be signed to clarify the ethical review responsibilities of all parties, to avoid repeated review, and to improve the efficiency and quality of ethical review in multi-center clinical trials of new drugs of TCM.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of Feiyanning Granule (FYN) on tumor growth and cell cycle distribution in mice with Lewis lung cancer, as well as its influence on G1/S cell cycle checkpoint dominating signaling RB-E2F1 bio-axis.</p><p><b>METHODS</b>Modeled C57BL/6 mice were randomly divided into 6 groups: the model group (A), the DDP treated group (B) peritoneally injected with cisplatin 0.1 mg on d1, d3 and d5 after modeling, and the 4 FYN treated groups (C-F), administered via gastrogavage with FYN Decoction, and FYN Granule in small-, median- and high- dose respectively for 14 days. The tumour inhibiting rate, tumour weight, and body weight of mice were observed after treatment; cell cycle distribution was detected by flow cytometry (FCM), RB-E2F1mRNA expressions in tumour tissue were analyzed by RT-PCR, and their protein expressions by Western blot.</p><p><b>RESULTS</b>Tumour weight in the 5 treated groups was lower than that in the model group (P < 0.05, P < 0.01). Body weight in group E was significantly higher than that in group A and B (P < 0.05, P < 0.01). FCM analysis showed the proportion of G0/G1 phase was higher in group E than in group A, B and C (P < 0.01), and cancer cell proliferation index (PI) in group E was lower than in group B (P < 0.05, P < 0.01). RT-PCR showed mRNA level of E2F1 was lower, but that of RB was significantly higher in group E than those in group A, B and C respectively (P < 0.01). Westem blot analysis showed the protein expression of E2F1 was lower in group E and B than that in group A (P < 0.05), while the protein expression of Rb in group E was higher than that in group A, B and C (P < 0.05).</p><p><b>CONCLUSION</b>The effect of FYN in inhibiting Lewis lung cancer growth was related to its intervention on cancer cell cycle distribution which blocks most tumor cells in G0/G1 phase. Moreover, FYN can reduce MDM2 expression, enhance P53 expression to influence cell cycle G1/S checkpoint dominating signaling, so as to achieve the effect of antagonizing lung cancer cell proliferation.</p>
