RESUMO

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.

RESUMO

In the present study, a gastric retention floating system for Brucea javanica oil, composed of alginate and carrageenan, was prepared using ionotropic gelation. Parameters for floatability, drug load, encapsulation efficiency, bead morphology, in vitro release, and in vivo gastric retention were evaluated. The optimized formulation via Box-Behnken design consisted of 1.7% alginate (W/V), 1.02% carrageenan (W/V), 1.4% CaCO (W/V), and a gelling bath of pH 0.8. The alginate-carrageenan-Brucea javanica oil beads had a porous structure and exhibited up to 24 h of in vitro floatability with a load capacity of 45%-55% and an encapsulation efficiency of 70%-80%. A 6-h sustained release was observed in vitro. The beads had a prolonged gastric retention (> 60% at 6 h) in fasted rats, compared to non-floating beads (15% at 6 h), as measured by gamma scintigraphy with single-photon emission tomography/computed tomography (SPET/CT). In conclusion, the alginate-carrageenan-Brucea javanica oil system showed enhanced oil encapsulation efficiency, excellent floating and gastric retention abilities, and a favorable release behavior.

RESUMO

Objective: Developed the core-matched nanoemulsions (CMNEs) to co-delivery paclitaxel-oleic acid (PTX-OA) prodrug and Brucea javanica oil (BJO) for increasing the antitumor effect. Methods: Antitumor effects and mechanism of PTX-OA/BJO CMNEs that the combination therapy which based on core-matched technology (CMT) were evaluated in vitro and in vivo. Results: The PTX-OA/BJO CMNEs were of nanoscale particle size (108.7 ± 2.3) nm and with entrapment efficiency of >95%. The PTX-OA/BJO CMNEs displayed concentration and time-dependent cytotoxicity against HepG-2 cells and increased G2/M phase block. More importantly, a significant reduction of the tumor volume with no obvious toxicity was observed in nude mice model following administration of PTX-OA/BJO CMNEs compared with the control treated with normal saline (P < 0.05), which suggested the excellent efficacy in vivo. It was further found that the enhanced effectiveness of PTX-OA/BJO CMNEs were associated with the ability of inducing apoptosis of the tumor cells, as well as obviously inhibiting tumor cell proliferation and the activity of TOPO Ⅱ. Conclusion: Co-encapsulation of two drugs with different mechanisms allows simultaneous interruption of diverse anticancer pathways, resulting in increased therapeutic response and lower toxicity.

RESUMO

Objective@#To investigate the effect of brucea javanica oil emulsion (BJOE) on the proliferation, collagen synthesis and ERK1/2 MAPK singaling pathway of hypertrophic scar fibroblasts (HSFs).@*Methods@#The human hypertrophic scar tissues were collected, and HSFs were isolated, cultured and identified in vitro. Cells were treated with BJOE under the concentration of 0.5, 1, 5, 10, 20 and 50 mg/ml for 24 h respectively; the half inhibitory concentration(IC50)of 24 h was calculated. The experimental groups were treated for 24, 48, 72 h by BJOE at the IC50, the control group was conventionally cultured without BJOE. Cell proliferation was detected by CCK-8 assay and cell cycle was determined by flow cytometry (FCM). The morphological changes of cells treated with BJOE at a concentration of IC50 for 24 h were observed. The protein expression levels of collagen Ⅰ, vimentin, ERK1/2 and p-ERK1/2 were measured by Western blot.@*Results@#The IC50 of BJOE was 1.176 mg/ml, so the concentration of 1 mg/ml was selected for the subsequent experiment. After 24, 48, 72 h treated with BJOE at a concentration of 1 mg/ml, the inhibition rates of BJOE on HSFs were (53.13±2.40)%, (75.07±2.67)%and (88.65±0.32)%, respectively. The difference was significant (P<0.05). Under the effect of BJOE, the number of HSFs significantly decreased, the interval between cells widened, cell protrusions were significantly shortened or even disappeared, and the cells became round. The percentage of cells decreased in S phase. Expression of type Ⅰ collagen, vimentin and p-ERK1/2 in HSF was significantly inhibited (P<0.05), while there was no significant difference in the expression of ERK1/2(P>0.05).@*Conclusions@#BJOE inhibites the proliferation of HSF and the synthesis of type Ⅰ collagen, and its mechanism is related to the inhibition of ERK1/2 phosphorylation and vimentin expression.

RESUMO

Objective: To optimize the preparation method of paclitaxel-oleic acid (PTX-OA)/Brucea javanica oil (BJO) core- matched nanoemulsions (CMNEs). Methods: PTX-OA/BJO was synthesized by esterification of PTX and OA, and determined by HPLC. Ultrasionic emulsification was used to prepare the PTX-OA/BJO CMNEs. The concentration of oil phase (A), quality of polysorbate 80 (B), and ultrasonic power (C) were selected as the significant factors after single-factor experiments and applied in L16(43) orthogonal array design with the average particle size as criterion. In addition, the physicochemical properties and cytotoxicity of PTX-OA/BJO CMNEs were tested. Results: Linear range of PTX-OA was 5-25 μg/mL, Y = 12.709 X + 6.252 0, r = 0.999 5. The optimized conditions of PTX-OA/BJO CMNEs were as follows: The concentration of oil phase was 6.50 mg/mL, the mass ratio of polysorbate 80 to oil phase was 3.5: 6.5 and the ultrasonic power was 120 W. The CMNEs prepared by the optimal conditions showed an entrapment efficiency of (100.6 ± 1.9)% and the nanoscale particle size was (108.7 ± 2.3) nm, PDI was 0.232 ± 0.038. The morphology of CMNEs examined by TEM exhibited a uniform and spherical shape. In vitro drug release was up to 67% after 48 h. After PTX-OA/BJO CMNEs sealed in a bottle were stored at 4 ℃ for 60 h, the average particle size and entrapment efficiency had no significant change. The cytotoxicity in vitro showed that the combined PTX-OA/BJO CMNEs could obviously inhibit the proliferation of HepG-2 cells. Conclusion: The current study demonstrates the feasibility of incorporating PTX-OA and BJO into a single CMNEs for the synergism in cancer therapy. Furthermore, the preparation of PTX-OA/BJO CMNEs has the advantages of practicability and simple operation, as well lays the foundation for the further mechanism research of the combined paclitaxel and BJO in oncotherapy.

RESUMO

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.

RESUMO

Objective: To study the acute and long-term toxicity of brucea javanica oil subnanoemulsion injections ( BJOSI ) . Methods:The mice were given BJOSI by intravenous injection. The acute toxicity was observed and LD50 in mice was calculated by Bliss method. To observe the long-term toxicological effects, Beagle dogs were injected intravenously BJOSI once a day for 8-week du-ration with the dose of 20, 10 and 6 ml·kg-1 , respectively followed by 3-week recovery period. Results:LD50 of BJOSI in mice was 7. 388 g·kg-1 with 95% confidence limits of 6. 306-8. 656 g·kg-1 . The long term toxicity test showed that all the detected indices were within normal range in all groups, including general state, weight changes,hematological indices,biochemical indices,EEG,organ coefficients, morphological and histological changes, while there was an upward tendency of ALT and Cr in every BJOSI group without dose-effect correlation. The dogs could completely recover in three weeks after the administration. Conclusion:The results suggest that BJOSI has low toxicity,while the pathological changes are reversible, and attention should be paid to the function of liver and kidney.

RESUMO

Objective To study the short-term clinical efficacy of treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection.Methods Clinical information of 42 patients with advanced gastrointestinal cancer were retrospectively collected.The 42 patients were divided into two groups according to treatments,with 21 case in the control group who were treated with javanica oil emulsion injection,as well as 21 case in the treatment group treated with lentinan injection and javanica oil emulsion injection.The efficacy,quality of life (QOL) and adverse effects were observed after treatment for 3 weeks.Results 81.0% (17/21)of patients in the treatment group improved in QOL,which was much higher than that in the control group 47.6% ( 10/21 ) ( x2 =5.081,P =0.024 ).The objective remission rate was 19.0% (4/21)and 14.3% (3/21)in the treatment group and the control group respectively,with no significant differece bwtween the two groups( x2 =0.171,P =0.679 ).the disease control rate was 85.7% (18/21)in the treatment group,which was significantly higher than that of 61.9% (12/21)in the control group( x2 =4.200,P =0.040 ).The incidence of adverse effect related to hematological toxicity,liver and kidney function,the digestive tract and itching of skin were similar between the two groups (Ps > 0.05 ).Phlebitis in the treatment group was not as frequent as that in the control group(P <0.05).Conclusion Treating patients with advanced gastrointestinal cancer with lentinan injection and javanica oil emulsion injection had high efficacy than treating only with javanica oil emulsion injection,and it improved QOL signifiantly with safety.

RESUMO

OBJECTIVE:To establish an RP-HPLC method for determination of the contents of oleinic acid and linolic acid in Brucea javanica oil. METHODS:The derivative fatty acid was obtained from extracting and separating process using ?-bromo-acetophenone as derivative reagent,K2CO3 as base and N,N-dimethylformamide (DMF) as solvent. The sample was separated on Shim-pack VP-ODS column(150 mm?4.6 mm,5 ?m); the detection wavelength was set at 242 nm. The mobile phase consisted of methanol-acetonitrile-water(30∶20∶50). RESULTS:The linear ranges of oleinic acid and linolic acid were 0.025~1.0 mg?mL-1(r=0.999 6) and 0.1 ~ 0.8 mg?mL-1(r=0.999 0),respectively. The average recoveries were 98.54% and 98.50%,respectively,and their RSD were 1.81% and 1.90%,respectively (n=6 each). CONCLUSION:The method is accurate and specific,and it is applicable for the quality control of B.javanica oil.

RESUMO

Objective To optimize the prescription and technology of Brucea javanica oil subnanoemulsion injection. Methods Using superfine Brucea javanica oil as oil phase,yolk lecithin and poloxamer 188 as the complex emulsifying agents. The dosage of oil,emulsifier and stabilizer were optimized and the preparation was optimized by orthogonal experiments. Results The optimum precription was 10% oil phase,1.2% emulsifier and 0.1% stabilizer. The optimum technology was that aqueous phase and oil phase mixed at 70 ℃,sheared 20 min by high speed shearing machine and then passed the ultra-high pressure nano homogenizer 6 times under the pressure of 900 bar. Conclusion The physical stability of Brucea javanica oil subnanoemulsion injection is good.
