Abstract
Malignant pleural mesothelioma (MPM) is a severe form of cancer that originates from mesothelium cells. Around 54-90% of mesotheliomas are associated with pleural effusions. Brucea Javanica Oil Emulsion (BJOE) is the processed oil derived from the seeds of Brucea javanica, which has shown potential as a treatment option for several types of cancer. Here, we present a case study of a MPM patient with malignant pleural effusion who received intrapleural injection of BJOE. The treatment resulted in the complete response of pleural effusion and chest tightness. While the precise mechanisms underlying the therapeutic effects of BJOE for pleural effusion are not yet fully understood, it has demonstrated a satisfactory clinical response without significant adverse effects.

Abstract
Brucea javanica oil emulsion (BJOE) has been used to treat tumor in China for more than 40 years. However, its components and effectiveness in the treatment of acute lymphocytic leukemia (ALL) and its mechanism of anti-cancer activity remain unknown. In the current study, high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) was used to analyze the components of BJOE. Then, the anti-leukemia effects of BJOE were examined both in vitro and in vivo using ALL Jurkat cells and the p388 mouse leukemia transplant model, respectively. The primary ALL leukemia cells were also used to confirm the anti-leukemia effects of BJOE. The apoptotic-related results indicated that BJOE induced apoptosis in Jurkat cells and were suggestive of intrinsic apoptotic induction. Moreover, BJOE inhibited Akt (protein kinase B) activation and upregulated its downstream targets p53 and FoxO1 (forkhead box gene, group O-1) to initiate apoptosis. The activation of GSK3β was also involved. Our findings demonstrate that BJOE has anti-leukemia effects on ALL cells and can induce apoptosis in Jurkat cells through the phosphoinositide3-kinase (PI3K) /Akt signaling pathway.

Abstract
Brucea javanica is an important Chinese folk medicine traditionally used for the treatment of dysentery (also known as inflammatory bowel diseases). Brucea javanica oil emulsion (BJOE), the most common preparation of Brucea javanica, has a variety of pharmacological activities. In this follow-up investigation, we endeavored to illuminate the potential benefit of BJOE on 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced Crohn's disease (CD) in rats and decipher the mechanism of action. The result illustrated that BJOE treatment significantly reduced the body weight loss, disease activity index and macroscopic scores, ameliorated shortening of colon length, arrested colonic histopathological deteriorations, lowered the histological scores in parallel to the model group. Furthermore, BJOE also decreased the levels of MPO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-17, IL-23 and IFN-γ), and increased the levels of anti-inflammatory cytokines (IL-4, IL-10 and TGF-β) as compared with the model group. In addition, the elevated mRNA expression of MMP-1, MMP-3 and RAGE induced by TNBS was remarkably inhibited by BJOE, SASP or AZA treatments, while the mRNA expression of PPAR-γ was significantly enhanced. Furthermore, the activation of TLR4/NF-κB signaling pathway was significantly inhibited by AZA and BJOE treatment when compared with that of TNBS-treated rats. Our study suggested that BJOE exerted superior therapeutic effect to SASP and AZA in treating TNBS-induced colitis in rats. The protective effect of BJOE may involve the inhibition of the TLR4/NF-κB-mediated inflammatory responses. These results indicated that BJOE held promising potential to be further developed into a novel candidate for the treatment of CD.

Abstract
Eligible studies were searched in Cochrane library, Pubmed, Medline, CBM, CNKI and VIP databases from establishment to June 2014. Two researchers independently identified 7 randomized controlled trials (RCTs) and extracted data of Brucea javanica oil emulsion injection combined with chemotherapy. Based on the published studies, the researchers analyzed them by RevMan 5.2 software and investigated the efficacy and safety of Brucea javanica oil emulsion injection combined with chemotherapy for patients with advanced gastric cancer by Meta analysis. Meta analysis showed that, compared with the simple chemotherapy, Brucea javanica oil emulsion injection combined with chemotherapy could increase objective response rate by 43%(RR=1.43, P<0.001). In addition, the incidence of neutropenia (RR=0.56, P<0.001), thrombocytopenia (RR=0.64, P=0.02), nausea, vomit (RR=0.66, P=0.002) decreased in these patients. However, the quality of life was not improved significantly in gastric carcinoma patients with combined therapy (RR=1.36, P=0.07). The paper suggested Brucea javanica oil emulsion injection combined with chemotherapy could increase efficacy and safety, which might be a promising therapy for patients with advanced gastric cancer.

Abstract
Background Brucea javanica oil emulsion (BJOE) is traditional Chinese medicine with implicated anti-tumor activity, which has been used for treating lung cancer in China. The aim of this investigation was to evaluate the effects and safety of intrapleural injection of BJOE in treating malignant pleural effusion (MPE). Methods The randomised controlled trials (RCTs) on the effects and safety of BJOE in treating MPE were searched from electronic medical database including MEDLINE, SCI, EMBASE, Cochrance Library and CNKI. A total of 14 RCTs with 1085 patients were involved in this meta-analysis. Results The overall response rate (ORR) of traditional chemotherapy drugs plus BJOE was higher than that of traditional chemotherapy drugs alone (p = 0.001; odds ratio = 1.39). Meanwhile, the combination of BJOE and traditional chemotherapy drugs improved the quality of life (QOL) of patients with MPE (p < 0.001; odds ratio = 1.56) compared with traditional chemotherapy drugs alone. Moreover, the participation of BJOE reduced the myelotoxicity and digestive reactions caused by traditional chemotherapy drugs (p < 0.05). Conclusions The efficacy and safety of traditional chemotherapy drugs plus BJOE was superior to traditional chemotherapy drugs alone via intrapleural injection in controlling MPE, which suggested that BJOE can be used to treat MPE.

Abstract
Brucea javanica oil emulsion (BJOE) has been used clinically to treat esophageal cancer combined with radiotherapy for numerous years in China. However, the detailed mechanism remains unclear. Thus, the effects of BJOE on the radiosensitivity of esophageal squamous cell carcinoma (ESCC) were evaluated in vitro and in vivo. The growth inhibitory effects of different BJOE concentrations were determined through an MTT assay. Radiosensitivity was evaluated through focal formation measurements and clone formation assays. The effects of BJOE on radiation-induced apoptosis were examined through flow cytometric analysis. The effects of BJOE on hypoxia-inducible factor 1α (HIF-1α) protein levels in vitro and in vivo were respectively analyzed through western blot analyses and enzyme-linked immunosorbent assays. BJOE significantly inhibited ECA109 cell proliferation in a dose- and time-dependent manner. Pretreatment with 2.5 mg/ml BJOE increased ECA109 radiosensitivity. BJOE in combination with radiation increased the DNA double-strand breaks. Compared with radiation alone, BJOE and radiation significantly increased the apoptotic rate of ECA109 cells. BJOE also decreased the HIF-1α protein levels in vitro and in vivo. The results from the present study demonstrated that BJOE enhanced the radiosensitivity of human ESCC. This finding was associated with the inhibition of HIF-1α expression. Therefore, BJOE may be a potential radiotherapy sensitization drug due to its significant anti-hypoxic activity.

Abstract
The present study aims to investigate the gastroprotective effect of Brucea javanica oil emulsion (BJOE) in animals. Gastroprotective potential of BJOE was studied on absolute ethanol, aspirin, reserpine and restraint plus water immersion-induced gastric ulcers in mice as well as glacial acetic acid (GAA) and pyloric ligation (PL)-induced gastric ulcers in rats. Except for ulcer scores, total acidity as well as pepsin activity as for the PL-induced gastric ulcer model and ulcer incidence as for the GAA-induced gastric ulcer model were also determined. Histopathological evaluation as for aspirin, reserpine, PL-induced models was conducted. Results showed that BJOE significantly (P < 0.05) reduced ulcer index in the mouse and rat models in a dose-dependent manner. It had significant (P < 0.05) suppressive effect on total activity of gastric juice as well in PL-induced model. Histopathological examination for the stomach samples confirmed the findings in the aspirin, reserpine or PL-induced gastric lesion models, which showed relatively complete mucosa structure and less inflammation. It is concluded that BJOE could be effective on gastric ulcer in rodents and its gastroprotective activity might be related to antioxidant, anti-inflammatory ability and promote gastric mucus secreted. The results may provide beneficial basis for increasing BJOE's clinical indication in future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Brucea javanica is an important traditional medicinal herb used for the treatment of dysentery, malaria, inflammation and cancer in southeast Asia for many years. However, the anti-inflammatory mechanism of Brucea javanica in the treatment of dysentery (also known as ulcerative colitis, UC) has not been fully illuminated. Brucea javanica oil emulsion (BJOE) is the major active and most common application form of Brucea javanica oil (BJO), which has a variety of pharmacological activities. The aim of this study was to investigate the potential anti-inflammatory effect of BJOE and possible mechanism of action on dextran sulfate sodium (DSS)-induced UC in mice. MATERIALS AND METHODS The components of BJOE were determined by gas chromatography-mass spectrometry (GC-MS). Balb/C mice with dextran sulfate sodium (DSS, 30mg/mL) induced colitis were treated with BJOE (0.5, 1 and 2g/kg) and two positive drugs (sulfasalazine, SASP, 200mg/kg; and azathioprine, AZA, 13mg/kg) once daily by gavage for 7 days. Mice in normal control group and DSS group were orally given the same volume of distilled water and soybean lecithin suspension (0.15g/kg) respectively. The effects of BJOE on DSS-induced UC were assessed by determination of body weight loss, disease activity index (DAI), colon length, histological analysis, as well as levels of pro-inflammatory cytokines. The mRNA expression of MPO, iNOS and COX-2 in colon tissues was detected by qRT-PCR. In addition, NF-κB p65, p-p65 and IκB-α, p-IκBα protein expression levels in colon tissues were investigated using Western blotting. RESULTS The major components of BJOE were found to be oleic acid (62.68%) and linoleic acid (19.53%) as detected by GC-MS. Our results indicated that BJOE, SASP and AZA showed beneficial effect on DSS-induced colitis in mice, and significantly reduced the body weight loss and DAI, restored the colon length, repaired colonic pathological variations, decreased histological scores, and decreased the levels of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8, IL-17 and IFN-γ) as compared with the DSS group. In addition, the mRNA expression of MPO, iNOS and COX-2 induced by DSS treatment was remarkably inhibited by BJOE, SASP or AZA treatments. Furthermore, when compared with DSS-treated mice, the activation of NF-κB was significantly inhibited by AZA and BJOE treatment. CONCLUSIONS Our study shows that BJOE possessed appreciable anti-inflammatory effect against murine experimental UC induced by DSS. The protective mechanism of BJOE may involve inhibition of NF-κB signal transduction pathways and subsequent down-regulation of inflammatory mediators. These findings suggest that BJOE might be an efficacious and promising therapeutic approach for the treatment of UC. Our investigation might also provide experimental evidence for the traditional application of Brucea javanica in the treatment of dysentery and might add new dimension to the clinical indications for BJOE.

Abstract
Brucea javanica oil emulsion (BJOE), the petroleum ether extract of B. javanica emulsified by phospholipid, is widely used in China as an anticancer agent. The extracts from B. javanica induce cancer cell death by various mechanisms; however, it is not known whether these mechanisms involve autophagy, which is an important process in cancer development and treatment. Thus, the current study aimed to investigate whether BJOE modulates autophagy in HCT116 human colon cancer cells and whether modulation of autophagy is an anticancer mechanism of BJOE. Immunoblotting was employed to analyze the protein expression levels of microtubule-associated protein light-chain 3 (LC3), a specific protein marker of autophagy, in HCT116 cancer cells following exposure to BJOE. The apoptosis rate of the HCT116 cancer cells was detected by performing an Annexin V-fluorescein isothiocyanate/propidium iodide assay. According to the effect of BJOE administration on autophagy in the HCT116 cancer cells (induction or suppression), a functionally opposite agent (autophagy suppressor or inducer) was applied to counteract this effect, and the apoptosis rate of the cancer cells was detected again. The role of autophagy (pro-survival or pro-death) was demonstrated by comparing the rates of apoptotic cancer cells prior to and following the counteraction. The results revealed that BJOE suppressed the protein expression levels of LC3, including the LC3-I and LC3-II forms, and induced apoptosis in the HCT116 cancer cells with a high level of basal LC3. The apoptosis-inducing activity of BJOE was significantly attenuated when autophagy was induced by the administration of trehalose, an autophagy inducer. The data indicates that autophagy inhibition is involved in BJOE-induced cancer cell death, and that this inhibition may be a potential anticancer mechanism of BJOE.
