This novel antineoplastic agent has beendemonstrated to have substantial clinical activity againstvarious tumors. In this paper, the mechanisms ofantitumor activity of elemene are reported. The in vitroeffect of elemene on the growth of leukemia cells wasevaluated by MTT assay. The IC50 values of elemene forpromyelocytic leukemia HL-60 cells and erythroleukemiaK562 cells were found to be 27.5 μg/ml and 81μg/ml,respectively, while IC50 for peripheral blood leukocytes(PBL) was 254.3 μg/ml. The inhibitory effect of elemeneon proliferation of HL-60 cells was associated with cellcycle arrest from S to G2M phase transition and withinduction of apoptosis. The apoptosis of tumor cells wasconfirmed by DNA ladder formation on gelelectrophoresis and characteristic ultrastructuralalternations. These results indicate that induction ofapoptosis contributes to the mechanisms of antitumoractivity of elemene.展开更多

Methods: 71 patients with advanced metastatic gastric cancer from April 2015 to April 2018 were randomly divided into two groups: the control group treated with SOX alone and the observation group treated with elemene combined SOX. The short-term and long-term therapeutic effects of the two groups were compared by the RECIST1.1 score and survival curve, and the differences of tumor markers, serological indicators and adverse reactions between the two groups were compared. Results: the objective remission rate (ORR) and clinical benefit rate (CBR) of the observation group were significantly higher than those of the control group (χ2=5.161, P=0.031;χ2=5.124, P=0.037);after treatment, the serum CEA, CA-199, IGF-1, MMP-9, IL-2 and IFN-γ levels of the observation group were significantly improved compared with those of the control group (P<0.05);compared with the two groups, the incidence of leucopenia, anemia, asthenia, nausea and vomiting in the observation group were significantly lower than that in the control group (P<0.05);the median tumor progression time (7.1 months, 95%CI=4.037-10.248) and median total survival time (8.8 months, 95%CI=6.634-10.907) in the observation group were significantly higher than that in the control group (4.9 months, 95%CI=2.324-6.839) and median total survival time (6.5 months, 95%CI=5.007-7.638), and the difference was statistically significant (P=0.001, P=0.026). Conclusion: elemene combined with SOX has a high short-term and long-term efficacy in patients with advanced metastatic gastric cancer, and its side effects are less, and its safety is higher, which has a certain clinical significance.展开更多

Methods: A total of 104 cases of patients with middle and advanced primary hepaticcarcinoma who were treated in the oncology department from August 2018 to January 2020 were included as the study objects, andwere randomly divided into two groups according to different treatment regimens, 52 cases in each group. Both groups were treatedwith TACE once;the cinobufagin injection group was given intravenous infusion with 500 mL of 5% glucose injection and 10 mLof cinobufagin injection once a day. The elemene injection group was given intravenous infusion with elemene injection of 0.4 geach time and once a day. Both groups were treated for two courses, 15 days of continuous treatment with a rest of 15 days beingone course. The clinical effect, the changes in the indexes of liver function including alanine amino transferase(ALT), aspartatetransaminase(AST) and total bilirubin(TBil), the scores of alpha-fetoprotein(AFP) and Karnofsky (KPS) and tumor volumes aswell as the difference in the incidences of adverse reactions between the two groups were observed and compared. Results: Thetotal clinical effective rate was 88.46% in the elemene injection group and 71.15% in the cinobufagin injection group, and thedifference was significant(P<0.05). After treatment, the levels of ALT, AST and TBil in serum in the two groups were significantlydecreased when compared with those before treatment, differences being significant(P<0.05). There was no significant differencebeing found in the comparison of the levels of ALT, AST and TBil in serum between the two groups (P>0.05). After treatment, thedecrease of AFP, tumor volume and the increase of KPS scores in the elemene injection group were significantly more than thosein the cinobufagin injection group, differences being significant (P<0.01). During treatment, there was no significant differencebeing found in the comparison of the total incidences of adverse reactions between the two groups(P>0.05). The adverse reactionsin the cinobufagin injection group were mainly nausea and vomiting, with higher incidence than that in the elemene injection group,the difference being significant (P<0.05). The adverse reactions in the elemene injection group were mainly pain at the injectionsite, with higher incidence than that in the cinobufagin injection group, the difference being significant (P<0.05).

It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE Tian introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".展开更多

The results indicate that the stress fields in this area are basically controlled by the push forces coming from the Pacific Plate and from the Tibet Plateau, and the WNW-ward action from the Pacific Plate play a more important role in North China plain block. In addition to that, the stress field in this area is also partly formed by the extension ac-tion from the mantle upwelling in perpendicular at the basin margins.展开更多

文摘Based on the constrained data from the observed stress orientation and the observed stress regime, the tectonic stress fields of the Great North China area has been simulated by using the pseudo-3D finite element method. The results indicate that the stress fields in this area are basically controlled by the push forces coming from the Pacific Plate and from the Tibet Plateau, and the WNW-ward action from the Pacific Plate play a more important role in North China plain block. In addition to that, the stress field in this area is also partly formed by the extension ac-tion from the mantle upwelling in perpendicular at the basin margins.
