Berberine

Cancer: Nasopharyngeal carcinoma
Action: Anti-inflammatory, inhibits STAT3
Growth inhibitory effects of berberine on multiple types of human cancer cells have been reported. Berberine inhibits invasion, induces cell cycle arrest and apoptosis in human cancer cells. The anti-inflammatory property of berberine, involving inhibition of Signal Transducer and Activator of Transcription 3 (STAT3) activation, has also been documented.
Berberine effectively inhibited the tumorigenicity and growth of an EBV-positive nasopharyngeal carcinoma (NPC) cell line (C666-1).
In vitro, berberine inhibited both constitutive and IL-6-induced STAT3 activation in NPC cells. Inhibition of STAT3 activation by berberine induced growth inhibition and apoptotic response in NPC cells. Tumor-associated fibroblasts were found to secret IL-6 and the conditioned medium harvested from the fibroblasts also induced STAT3 activation in NPC cells. Inhibition of tumorigenic growth of NPC cells in vivo was also correlated with effective inhibition of STAT3 activation.

Elemene Injection is made from mixed liquid of β-, γ-, δ-elemene. It can increase the therapeutic effect and lower the toxicity and side-effects of radiotherapy and chemotherapy when combined with routine regiments of radiotherapy or chemotherapy for lung cancer, liver cancer, esophageal cancer, nasopharyngeal cancer, brain tumors, metastatic bone cancer and other malignancies. It can also be used for intervention, intraperitoneal chemotherapy, and pleural effusion or ascites caused by cancer (Drug Information Reference in Chinese: See end. 2000-12).

NSCLC; Chemotherapy

Randomized controlled trials (RCTs) of elemene injection combined with cisplatin chemotherapeuties in treating small cell lung cancer (NSCLC) were collected by Xu et al., (2013). Their meta-analysis results suggested that compared with cisplatin chemotherapy alone, the combination of elemene injection and cisplatin chemotherapeutics showed a higher clinical benefit rate (OR = 2. 03, 95% CI:1.43-2. 88, P <0. 000 1) and a better quality of life (OR = 3.23, 95% CI:2. 20-4. 74, P <0. 000 01). As well, the combination could also reduce leucopenia (OR =0. 50, 95% CI:0. 33-0. 76, P <0. 001), and thrombocytopenia (OR =0. 38, 95% CI:0. 16-0. 85, P <0. 02), increase CD4 (MD = 3.32, 95% C1:2. 94-3.70, P <0. 000 01), and CD4/CD8 (MD = 0. 36, 95% CI:0. 28-0. 44, P < 0. 000 01), and relieve gastrointestinal reactions such as nausea and vomiting (OR = 0. 37, 95% CI: 0. 19-0. 71, P = 0. 003).

The analysis indicates that elemene can enhance the chemotherapeutic effect on NSCLC, improve the quality of life, and reduce adverse effect of platinum-contained chemotherapeutics, thereby being worth promoting in clinic.

Lung Cancer

Randomized controlled clinical trials related to the use of β>-elemene injection, as an adjunctive treatment for lung cancer, were retrieved from the Chinese Biomedical (CBMweb), Chinese Medical Current Content (CMCC), China National Knowledge Infrastructure (CNKI), ChinaInfo, Cochrane Central Register of Controlled Trials; MEDLINE, EMBASE, OVID and TCMLARS databases.

A total of 21 source documents (1,467 patients) matched pre-specified criteria for determining the effectiveness and safety of β>-elemene injection as an adjunctive treatment for lung cancer. Five studies involving 285 NSCLC patients reported a higher 24-month survival rate (39.09%) with the adjunctive treatment than with chemotherapy alone (26.17%; RR, 1.51; 95% CI, 1.03 to 2.21). Four studies involving 445 patients reported that the increased probability for improved performance status for patients treated with elemene-based combinations was higher than that of patients treated with chemotherapy alone (RR, 1.82; 95% CI, 1.45 to 2.29).

The results from a subgroup analysis on 12 studies involving 974 NSCLC patients and 9 studies involving 593 patients with both SCLC and NSCLC showed that the tumor control rate for NSCLC improved more in the elemene-based combinations treatment group (78.70%) than in the chemotherapy alone control group (71.31%; RR, 1.06; 95% CI, 1.00 to 1.12). The tumor response rate for NSCLC also improved more among patients treated with elemene based combinations (50.71%) than among patients treated with chemotherapy alone (38.04%; RR, 1.34; 95% CI, 1.17 to 1.54). The effectiveness of chemotherapy for the treatment of lung cancer may improve when combined with β-elemene injection as an adjunctive treatment. The combined treatment can result in an improved quality of life and prolonged survival (Wang et al., 2012).

Malignant Ascites

The effective combination therapy for malignant ascites, the therapeutic value of the combination of Endostar, a modified recombinant human endostatin, and β-elemene, an active component of a traditional Chinese herb, in an H22 mouse malignant ascites model was investigated by Jiang et al. (2012). The results of this study revealed that the combination therapy had significant synergistic effects on the inhibition of ascites formation and a deceased number of tumor cells and protein levels in ascites compared with the results of treatment with a single agent. A decreased peritoneal microvascular permeability and reduction in VEGF, MMP-2 and hypoxia inducible factor 1α(HIF1α) was noted in the combination group, when compared with single agent treatment.

These studies found that in the ascitic tumor cells, the protein levels of VEGF and MMP-2, as well as levels of VEGF mRNA, were significantly inhibited by the combination therapy. The potentiating effects of the combination of Endostar with β-elemene suggest that this novel therapy may yield an effective therapy for the treatment of malignant ascites.

Glioblastoma

Anti-proliferation of glioblastoma cells induced by beta-elemene was dependent on p38 MAPK activation. Treatment of glioblastoma cell lines with beta-elemene, led to phosphorylation of p38 MAPK, cell-cycle arrest in G0/G1 phase and inhibition of proliferation of these cells. Inhibition of p38 MAPK reversed beta-elemene-mediated anti-proliferation effect. Furthermore, the growth of glioblastoma cell-transplanted tumors in nude mice was inhibited by intraperitoneal injection of beta-elemene (Yao et al., 2008).

Breast Cancer; Chemotherapy

Beta-elemene had synergistic effect with Paclitaxel, and its possible mechanism might be correlated with down-regulating the cell-cycle protein cyclin-B1 expression and up-regulating the P27(kip1) expression. Beta-elemene (20 and 40 microg/mL respectively) and Paclitaxel (0.016 and 0.008 microg/mL respectively) synergistically inhibited cell proliferation of MB-468 breast cancer cells, with Q value > 1.15. Beta-elemene alone (52.59 microg/mL) apparently decreased the expression of cyclin-B1 protein. The expression of cyclin-B1 protein in the combined group was also lower than that in the PI group (1.698 microg/mL). The expression of P27(kip1) was up-regulated when compared with that in the betaI group or the PI group (Cai et al., 2013).

Gastric Cancer

TCM therapy applied in the 34 patients assigned in the TCM group (group I) included intravenous injection of Cinobufotalin, beta-elemene, or orally taking of anti-cancer Chinese herbs. The same TCM was also applied in the 36 patients of the combined treatment group (group II), but in combined use of FOLFOX chemotherapeutic protocol.

The median survival period in group II was 31 months, while it was 30 months in group I; the 1-, 2-, 3-year survival rates in group II were 88.89%, 84.38% and 59.26%, and those in the group I were 82.35%, 71.43% and 65.00%, respectively with insignificant difference between the two groups (chi2 = 0.298, P > 0.05); QOF in group I was significantly superior to that in group II (P < 0.05), and the adverse reaction occurrence was significantly less in group I than that in group II.

Chinese medicine treatment can improve the QOF and prolong the survival period of patients with progressive gastric cancer with few side-effects (Liu et al., 2008).
