ABSTRACT
OBJECTIVE To study the antitumor activity and underlying mechanisms of Xiaoaiping injection(Xap)combined with gefitinib(Gef)in nude mice bearing resistant non-small cell lung cancer (NSCLC) cells H460 or H975. METHODS BALB/c nude mice were inoculated with human NSLCL cells H460 or H1975 and the drug treatment did not start until the tumor volume reached 50-100 mm3. The tumor bearing mice were divided into four groups:control group,Xap group(5 g · kg-1,ip),Gef group (50 mg · kg-1,ig),and Xap plus Gef group. All the administration lasted for 21 d continuous. Tumor volumes were measured two or three times per week,and the body weight of animals was re-corded. At the end of the test,tumors were weighed after the sacrifice of mice. Tumor inhibition rate and relative tumor proliferation rate were calculated based on tumor weight and tumor volume. The related biomarkers and proteins in tumor tissues were detected by immunohistochemistry and Western blot assay, respectively. RESULTS Compared with the control group,no significant effect was observed on the growth of H460 and H1975 xenografts in groups of Xap or Gef alone in nude mice. However,the two-drug combination significantly suppressed tumor volume,with (1103 ± 340) versus (3020 ± 450) mm3 for H460 and(487 ± 153)versus(1269 ± 161)mm3 for H1975,respectively(P<0.05). The combined Xap and Gef application also significantly reduced the tumor weight,with(1.20±0.52)versus(2.78± 0.93)g for H460 and(0.52 ± 0.32)versus(0.92 ± 0.42)g for H1975,respectively(P<0.05). The relative tumor proliferation rate and inhibition rate in the combination group was 42.1%and 43.5%for H460(P<0.01),43.0%and 52.5% for H1975(P<0.01). Compared with Xap and Gef drug alone,their combination showed significant difference in reducing tumor weight,suppressing tumor proliferation rate and increasing tumor inhibition rate(P<0.05). Immunohistochemistry results showed that each drug alone had no effect on tumor angiogenesis markers of vascular endothelial growth factor(VEGF)and CD105 expression,or on drug resistance related proteins of p-ERK,p-Akt and p-mTOR,whereas the combination of Xap and Gef obviously reduced the expression of these biomarkers in H460 and H1975 tumor tissues. The decreased drug resistance related proteins of p-PI3K and its downstream molecules p-Akt,p-ERK and p-mTOR by the two-drug combination were also confirmed by Western blot results(P<0.01,compared with control), and showed significant difference compared with each single treatment(P<0.05). CONCLUSION The addition of Xap significantly improves the antitumor activity of Gef in H460 and H1975 xenografts,and this synergistic effect may be ascribed to the inhibition of tumor angiogenesis,the down-regulation of PI3K and its downstream signaling molecules which are associated with drug resistance.
ABSTRACT
OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.
ABSTRACT
This study was designed to investigate the effect of Xiao-Ai-Ping injection on cancer angiogenesis. CCK8 assay and BrdU incorporation immunofluorescence assay were used to detect the effect of Xiao-Ai-Ping injection on HUVECs proliferation; wound healing assay and transwell assay were employed to test the effect of Xiao-Ai-Ping injection on HUVECs migration. The anti-angiogenic effect of Xiao-Ai-Ping injection was examined by tube formation assay, rat aortic ring assay and chicken chorioallantoic membrane (CAM) assay. ELISA assay was used to measure the secretion of vascular endothelial growth factor (VEGF); and the activation of vascular endothelial growth factor receptor 2 (VEGFR2) protein and its downstream signaling pathways were examined by Western blot. Our data demonstrated that Xiao-Ai-Ping injection inhibited HU-VECs proliferation in a time-and dose-dependent manner, and the IC50 (mg·mL-1) values for 24, 48 and 72 h were 48.7±7.14, 29.1±2.25 and 22.0±4.53, individually. Xiao-Ai-Ping injection inhibited HUVECs DNA synthesis and migration. Xiao-Ai-Ping injection suppressed HUVECs tube formation, and reduced microvessel sprouting from rat aortic rings and vessel growth in CAMs. Furthermore, Xiao-Ai-Ping injection attenuated the secretion of VEGF, and inhibited the expression of p-VEGFR2 and phosphorylation of protein kinase B (p-AKT). We conclude that Xiao-Ai-Ping injection inhibits angiogenesis by down-regulation of VEGF signaling and AKT pathway.

Methods The hepatocellular carcinoma cell line Hepal-6 was treated with XAP at doses of 30 mg/ml(the high concentration group), 20 mg/ml (the moderate concentration group) and 10 mg/ml (the low concentration group) for 24 h, 48 h and 72 h, respectively. The MTT assay was used to detect the inhibitory effects of XAP on cell growth. The cell morphological alteration was observed after HE staining, and the apoptosis rates were assayed by flow cytometry. Results XAP produced an obvious time-and-dose-dependent inhibitory effect on the Hepa1-6 cells (P<0.01), and the cell differentiation trend was benign on light microscopy. After 48 h Hepa1-6 cells were incubated by XAP, there was an apoptosis peak, and the apoptosis rate was increased statistically in XAP group with the increasing XAP concentration [(7.65±0.40)%, (11.26±1.09)% and (26.71±0.85)% in low, moderate and high concentration group, respectively]compared with that in the controls (2.88 ±0.30)%, P < 0.01). Conclusion XAP produced obvious time-and-dose-dependent inhibitory effects on Hepa1-6 cells. Inhibiting DNA synthesize and inducing apoptosis of tumor cells may involve in the mechanisms of antineoplastic effect.
ABSTRACT
Objective To study the effect of Xiaoaiping injection on Caov-3 human ovarian cancer cells and its mechanisms. Methods After treatment with Xiaoaiping injection, viability of Caov-3 cells determined by MTT method. Phase contrast microscopy was used to observed the morphological changes of Caov-3 cells. Cell cycle was assessed by FACS. Cell signaling pathway protein-Akt and pAkt, and cell cycle associated protein-p27 were measured by western blot. Results Xiaoaiping injection inhibited the growth of Caov-3 human ovarian cancer cells in a dose and time dependent manner. Xiaoaiping injection induced G0/G1 phase arrest of Caov-3 cells, accompanied by pAkt down-regulation and p27 up-regulation. Conclusion Xiaoaiping injection can inhibit the proliferation of Caov-3 human ovarian cancer cells by inhibiting PI3K/Akt signaling pathway.
ABSTRACT
Objective To develop a HPLC method for the determination of chlorogenic acid in xiaoaiping injection in human plasma.Methods The analytical column was packed with Hypersil ODS C18 (250 mm×4.6 nm,5 μm).The mobile phase was acetonitrile-0.4% phosphoric acid solution(13:87).The flow rate was 1 ml/min,and detection wave length was set at 327 nm.Results The linear ranges were 2.5～60.0 mg/L chlorogenic acid in human plasma,with the correlation coefficients of 0.9996.The Low limit of detection was 0.25 μg/ml.The method and extraction recovery were 100.1%～102.6%and 78.6%～80.3%.The relative standard deviation value for the within-day and between-day precision were less than 3.9%.Conclusion The method is simple,sensitive for the determination of chlorogenic acid in xiaoaiping injection in human plasma.
