[show abstract][hide abstract] ABSTRACT: The epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), such as gefitinib and erlotinib, have shown promising therapeutic efficacy in nonsmall cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor- (EGFR-) activating mutation. However, the inevitable recurrence resulting from acquired resistance has limited the clinical improvement in therapy outcomes. Many studies demonstrate that hepatocyte growth factor- (HGF-) Met axis plays an important role in tumor progression and drug sensitivity. HGF may induce resistance to EGFR-TKIs in EGFR mutant lung cancer cells by Met/PI3K/Akt signaling. The purpose of this study was to determine whether bufalin, a major bioactive component of Venenum Bufonis, could reverse HGF-induced resistance to reversible and irreversible EGFR-TKIs in mutant lung cancer cells PC-9, HCC827, and H1975. Our studies showed that bufalin could reverse resistance to reversible and irreversible EGFR-TKIs induced by exogenous HGF in EGFR mutant lung cancer cells by inhibiting the Met/PI3K/Akt pathway and inducing death signaling. These results suggested that bufalin might have a potential to overcome HGF-induced resistance to molecular-targeted drugs for lung cancer.

[show abstract][hide abstract] ABSTRACT: This study investigated the dual control mechanism of the Shuanghuang Shengbai granule in modulating the cell cycle in Lewis-bearing mice with cyclophosphamide induced myelosuppression.
Thirty Lewis-bearing mice were randomly grouped into an untreated group, control group, and treated group. Both treated and untreated groups were intraperitoneally injected with cyclophosphamide to produce a myelosuppression model. Mice in the treated group were fed with the Shuanghuang Shengbai granule (40 g/day) for 6 consecutive days. Standard blood tests and the count of bone marrow nuclear cells were performed, and the cell reproductive cycles of bone marrow and tumors were measured in these mice. In addition, the western blot approach was used to measure the upstream activating signals of CyclinD-CDK4/6 such as c-Myc and CDC25A, the upstream suppression signals such as p16INK4a, and the expression of downstream activated signals such as Rb, pRB, and E2F. All of the tested results were validated by reverse transcription quantitative real-time polymerase chain reaction.
The results showed that the Shuanghuang Shengbai granule could elevate the count of leukocyte and bone marrow nuclear cells of Lewis-bearing mice with cyclophosphamide induced myelosuppression. It could also stimulate bone marrow cells to move from G0/G1 phases to S phase, accelerating the progress of the cell reproductive cycle and increasing the cell proliferation index. Simultaneously, the Shuanghuang Shengbai granule could also suppress cancer cells moving from G0/G1 phase to S phase, reducing the proliferation index. The tumor weight of Lewis-bearing mice in the treated group was much less than those of the control group. Expression levels of c-Myc, CDC25A, Rb, pRb, and E2F of bone marrow in Shuanghuang Shengbai granule-treated mice was higher compared to the control group, whereas they were lower in the cancer cells.
The experimental results demonstrate that the Shuanghuang Shengbai granule has dual control on the cell reproductive cycles in cancer cells and bone marrow nuclear cells in Lewis-bearing mice.

Previous in vivo experiment had confirmed the Feiyanning's intervention effect on checkpoint signaling of G1/S in the cell cycle. This study was to further observe the expressions of nucleosome conformation-regulating factors intervened by Feiyanning decoction in S phase.
Lewis lung carcinoma models of C57BL/6 mice were established. Sixty mice were randomly divided into four groups: normal control group, model control group, Feiyanning group, and cisplatin group. There were 15 mice in each group. Tumor weight and tumor inhibition rate were observed. In addition, the cell cycle distribution was detected by flow cytometry and the proliferation index was calculated. Furthermore, mRNA and protein expressions of H3-K56, regulator of Ty1 transposition 109 (Rtt109), antisilencing function 1 (Asf1) and E2F1 were analyzed by real-time polymerase chain reaction and Western blot methods, respectively.
The tumor weights of mice in the Feiyanning group and the cisplatin group were lower than those in the model group (P<0.01), with tumor inhibition rates of 27.92% and 42.50%, respectively. Cancer cell proliferation index and proportion of cancer cell population in S phase in the Feiyanning group were significantly lower than those in the cisplatin group (P<0.01). The mRNA and protein levels of H3-K56, Rtt109, Asf1, E2F1 in the Feiyanning group were lower than those in the model group (P<0.05).
Feiyanning plays a role in intervening in the abnormal cell cycle by nucleosome conformation-regulating factors and thus inhibits the lung cancer cell proliferation.

[show abstract][hide abstract] ABSTRACT: Tumor markers are widely used in clinical practice and have become important indicators in assessing cancer progress. There is increasing concern that chemotherapy combined with traditional Chinese medicine has effects in decreasing the level of tumor markers.
To investigate the effects of chemotherapy combined with Kangliu Zengxiao Decoction (KLZX), a compound Chinese herbal drug, on tumor markers carbohydrate antigen 50 (CA 50), cytokeratin 19 fragment (CYFRA21-1) and carcinoembryonic antigen (CEA) in patients with advanced non-small-cell lung cancer (NSCLC) and to explore the relationships between clinical efficacy and tumor markers.
Patients were included from Punan Hospital of Shanghai Pudong New District and Longhua Hospital between October 2008 and December 2009. Seventy-four subjects with advanced NSCLC were randomly assigned into treatment group (n=37) and control group (n=37). Patients in the control group were treated with chemotherapy alone while patients in the treatment group were treated with chemotherapy combined with KLZX. Chemotherapy of NP (vinorelbine + cisplatin) was given for two cycles and patients in the treatment group were administered with KLZX during chemotherapy.
Levels of CA50, CYFRA21-1 and CEA before and after treatment were evaluated and the relationship between changes in levels of tumor makers and tumor size, clinical symptoms and living condition score (Karnofsky score) was analyzed.
No patients achieved a complete remission. The disease control rates (complete remission (CR)+partial remission (PR)+no change (NC)) were 89.20% (33/37) and 70.30% (26/37) in the treatment and control group respectively (P<0.05). The levels of CA50, CYFRA21-1 and CEA were clearly decreased in the treatment group after treatment (P<0.05) while also decreased in the patients without progression of disease. There were no obvious changes of CA50, CYFRA21-1 and CEA in the control group, and there was even a trend of increase. Furthermore, the improvement rates of clinical syndrome were 51% (19/37) vs 11% (4/37) (P<0.05) in the treatment group and control group respectively. The total response rates of quality of life were 91.89% (34/37) vs 56.76% (21/37) (P<0.01) in the treatment and control group respectively.
Combined chemotherapy with KLZX in treating advanced NSCLC can acquire better stabilizing tumor foci, decrease levels of tumor markers and improve the clinical symptoms and Karnofsky score.

[show abstract][hide abstract] ABSTRACT: To describe the characteristic of tongue images of patients with lung cancer of different Chinese medicine (CM) syndromes and to reveal the elemental rule on the changes of the tongue images.
A total of 207 patients with lung cancer were divided into four syndrome groups according to the theory of CM: Fei and Shen deficiency syndrome (Group A, 72 cases), Pi deficiency and phlegm deficiency and phlegm) and Shen (deficiency and phlegm) deficiency syndrome (Group A, 72 cases), Pi (deficiency and phlegm) deficiency and phlegm dampness syndrome (Group B, 57 cases), phlegm-heat retention in Fei (Group C, 36 cases) and yin asthenia generating intrinsic heat syndrome (Group D, 42 cases). The tongue parameters were detected by tongue image digital analysis instrument, and the tongue images were described with qualitative, tongue color and quantitative analysis, respectively. The International Commission on Illumination (CIE) L·a·b (CIELAB) color model was used for the quantitative classification.
There was a significant statistical difference between different syndrome groups of lung cancer on tongue color, coating color, and thickness of tongue coating (P<0.01), and there was significant statistical difference between the four syndrome groups on Lab values of the tongue and coating (P<0.05). The correct identification rate of discriminant function on the raw data was 65.7%, including 72.2% for Group C, 69.4% for Group A, 69.0% for Group D and 54.4% for Group B.
A tongue image digital analysis instrument can objectively describe the tongue features of patients with different syndromes of lung cancer. The tongue diagnosis is very important to syndrome differentiation in CM. Tongue diagnosis should be combined with some important characteristics of syndromes in the future to establish a "combination of four examination methods, including inspection, auscultation, interrogation, and pulse-feeling and palpation" in the tongue diagnostic system.

[show abstract][hide abstract] ABSTRACT: To observe the effect of Feiyanning Granule (FYN) on tumor growth and cell cycle distribution in mice with Lewis lung cancer, as well as its influence on G1/S cell cycle checkpoint dominating signaling RB-E2F1 bio-axis.
Modeled C57BL/6 mice were randomly divided into 6 groups: the model group (A), the DDP treated group (B) peritoneally injected with cisplatin 0.1 mg on d1, d3 and d5 after modeling, and the 4 FYN treated groups (C-F), administered via gastrogavage with FYN Decoction, and FYN Granule in small-, median- and high- dose respectively for 14 days. The tumour inhibiting rate, tumour weight, and body weight of mice were observed after treatment; cell cycle distribution was detected by flow cytometry (FCM), RB-E2F1mRNA expressions in tumour tissue were analyzed by RT-PCR, and their protein expressions by Western blot.
Tumour weight in the 5 treated groups was lower than that in the model group (P < 0.05, P < 0.01). Body weight in group E was significantly higher than that in group A and B (P < 0.05, P < 0.01). FCM analysis showed the proportion of G0/G1 phase was higher in group E than in group A, B and C (P < 0.01), and cancer cell proliferation index (PI) in group E was lower than in group B (P < 0.05, P < 0.01). RT-PCR showed mRNA level of E2F1 was lower, but that of RB was significantly higher in group E than those in group A, B and C respectively (P < 0.01). Westem blot analysis showed the protein expression of E2F1 was lower in group E and B than that in group A (P < 0.05), while the protein expression of Rb in group E was higher than that in group A, B and C (P < 0.05).
The effect of FYN in inhibiting Lewis lung cancer growth was related to its intervention on cancer cell cycle distribution which blocks most tumor cells in G0/G1 phase. Moreover, FYN can reduce MDM2 expression, enhance P53 expression to influence cell cycle G1/S checkpoint dominating signaling, so as to achieve the effect of antagonizing lung cancer cell proliferation.

[show abstract][hide abstract] ABSTRACT: To study the effects of Feiyanning Decoction, a compound traditional Chinese herbal medicine, on proliferation of lung adenocarcinoma cell line A549 cells and their production of interleukin-6 (IL-6) and IL-8 induced by tumor necrosis factor-alpha (TNF-alpha).
A549 cells were incubated with rat serum containing Feiyanning Decoction at 15% for 24, 48 and 72 h respectively. The cell proliferation was examined by 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2, 4-disulfophenyl)-2H-tetrazolium, monosodium salt assay (WST-8). The production of IL-6 and IL-8 was tested by enzyme-linked immunosorbent assay after 48-hour treatment of reagents, and the expressions of IL-6 and IL-8 mRNAs were detected by reverse transcription-polymerase chain reaction.
Serum containing Feiyanning Decoction had obvious inhibitive functions in A549 cell proliferation after 48- and 72-treatment. TNF-alpha (1 microg/L) strongly induced the production of IL-6 and IL-8 as compared with the control serum in A549 cells, and the induced cytokine production was significantly suppressed by 15% serum containing Feiyanning Decoction (P<0.01). In addition, serum containing Feiyanning Decoction could inhibit the mRNA expressions of IL-6 and IL-8 (P<0.01).
Feiyanning Decoction can inhibit IL-6 and IL-8 production induced by TNF-alpha. It is therefore expected to be a new strategy for treating lung cancer.

[show abstract][hide abstract] ABSTRACT: To explore the dual regulatory effects of Shuanghuang Shengbai Granule, a compound traditional Chinese herbal medicine, on cell cycle in Lewis-bearing mice with chemotherapy-induced myelosuppression.
Thrity Lewis-bearing mice were randomly divided into control group, untreated group and treated group. A model of myelosuppression was established by peritoneal injection of cyclophosphamide to Lewis-bearing mice. Mice in the treated group were treated with Shuanghaung Shengbai Granule for 6 days. Cell cycle progressions of cells collected from bone marrow and tumor tissues were assayed by flow cytometry, and proliferation index (PI) was also calculated. Expressions of cyclin-dependent kinase 4 (CDK4), cyclin-dependent kinase 6 (CDK6) and cyclin D1 in bone marrow and tumor tissues were detected by Western blotting and immunohistochemical method.
Percentages of bone marrow and tumor cells in G0/G1 phase in the untreated group were lower than those in the control group; however, the PI of untreated group was higher than that of the control group. The expressions of CDK4, CDK6 and cyclin D1 in bone marrow and tumor tissues in the untreated group were increased as compared with the control group. Compared with the untreated group and the control group, the percentage of bone marrow cells in G0/G1 phase was decreased, and the PI of bone marrow cells and the expressions of CDK4, CDK6 and cyclin D1 were increased in bone marrow in the treated group. However, the percentage of tumor cells in G0/G1 phase in the treated group was increased, and the PI of tumor cells and the expressions of CDK4, CDK6 and cyclin D1 in tumor tissues were decreased as compared with the untreated and control groups.
Shuanghuang Shengbai Granule may have a function of cell cycle dual regulation in Lewis-bearing mice with chemotherapy-induced myelosuppression by regulating the expressions of CDK4, CDK6 and cyclin D1 in bone marrow and tumor tissues.

A549 cells were incubated with rat serum containing Feiyanning at different concentrations for 24 and 48 h, respectively. Morphology of cells was observed by an inverted microscope after treatment with reagents. The cell proliferation was examined by 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium, monosodium salt (WST-8) assay. The expressions of NF-kappaB and inhibitor kappaBalpha (IkappaBalpha) were studied by Western blotting. NF-kappaB-dependent luciferase reporter (3 x kappaB-luc) was transfected for 24 h, and the cells were treated with the reagents for 24 h, and then the transcriptional activity of NF-kappaB promoter was detected by luciferase assay.
TNF-alpha (1 microg/L) strongly induced the expression of NF-kappaB by approximately 1.76-fold compared with the control in the nuclei of A549 cells, and the induced NF-kappaB expression was significantly suppressed by addition of Feiyanning (P < 0.01). In addition, Feiyanning inhibited the transcriptional activity of the NF-kappaB promoter. However, we observed no significant changes in IkappaBalpha expression (P > 0.05).
Feiyanning Decoction can markedly inhibit human lung cancer A549 cell proliferation, which may be partly due to inhibition of NF-kappaB activation induced by TNF-alpha. It is therefore expected to be a new strategy for treating lung cancer.

HUVECs were isolated from the new-born umbilical core of human. Serum containing Feiyanning was prepared in SD rats by oral gavage of the Feiyanning Decoction for three days. The inhibitory effects of different contents of serum containing Feiyanning on the proliferation of HUVECs, human lung adenocarcinoma cell A549, and HUVECs cultured with A549-conditioned media were observed by sulforhodamine B (SRB) method; the effects on migration of HUVECs were inspected by using Boyden Chamber Transwell method, and the effects on tube formation of HUVECs were evaluated by cavity forming experiment.
Serum containing Feiyanning at a concentration of 25%, 37.5% or 50% inhibited the proliferation of both the HUVECs and the HUVECs cultured with A549-conditioned media (P < 0.01, P < 0.05). High concentration serum containing Feiyanning inhibited the proliferation of A549 cells. Sera containing Feiyanning at concentrations of 12.5% to 37.5% inhibited the migration of HUVECs induced by 20% fetal bovine serum (P < 0.01, P < 0.05) and the formation of the primary tube of HUVECs.
Feiyanning Decoction can inhibit the angiogenesis of HUVECs, which may be one of its mechanisms in inhibiting the invasion metastases of lung cancer.

A total of 24 C57BL-6 mice were used in this study. Lewis cells were subcutaneously injected to the right armpit to establish the tumor-bearing model. The C57 mice bearing Lewis tumor were randomly divided into untreated group, chemotherapy group, FYN group and chemotherapy plus FYN group. Reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry were employed to measure the expressions of CXCL12 and CXCR4 mRNAs and proteins in Lewis tumors in C57 mice respectively.
The rates of lung cancer metastasis in the FYN group and the chemotherapy plus FYN group were markedly lower than that in the untreated group or the chemotherapy group. The expressions of CXCL12 and CXCR4 mRNAs and proteins appeared in tumor tissue in the untreated group. Although there was no significant difference in the expressions of mRNA and protein of CXCL12 among all groups (P>0.05), the expressions of mRNA and protein of CXCR4 in the untreated group and the chemotherapy group were markedly lower than those in the FYN group and the chemotherapy plus FYN group (P<0.05).
FYN can inhibit the metastasis of Lewis tumor loaded in C57 mice. Its mechanisms may be related to its down-regulation of the expression of chemokine receptor CXCR4, and affecting the role of CXCL12-CXCR4 biological axis.

Thirty-two nude mice were transplanted with human lung adenocarcinoma cells (A549 cells) to make the mice model, and then randomly divided into four groups: untreated group (n=8), diamminedichloroplatinum (DDP) group (n=8), Feiyanning group (n=8) and DDP plus Feiyanning group (n=8). The nude mice in DDP group and DDP plus Feiyanning group were treated with DDP 0.1 mg by peritoneal injection on the 1st, 3rd and 5th day after model establishment. The nude mice in the Feiyanning group and the DDP plus Feiyanning group were treated with Feiyanning Decoction for 21 days. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of HIF-1alpha mRNA in tumors, and immunohistochemical method was used to detect the expressions of p-Akt and HIF-1alpha proteins in tumors.
The inhibition rates of tumor in Feiyanning group and DDP plus Feiyanning group were 34.17% and 64.38% respectively. RT-PCR showed that the expression level of HIF-1alpha mRNA in DDP plus Feiyanning group was lower than that in the untreated group (P<0.05). Immunohistochemical staining showed that the optical density (OD) indexes of HIF-1alpha in DDP group, Feiyanning group and DDP plus Feiyanning group were lower than that in the untreated group (P<0.01). The expressions of p-Akt in the Feiyanning group and DDP plus Feiyanning group were lower than that in the untreated group either (P<0.05).
Feiyanning Decoction is effective in inhibiting the growth of lung cancer. And the effect of inhibiting the expression of HIF-1alpha protein by Feiyanning Decoction may correlate with down-regulation of p-Akt.

Adopting prospective randomized controlled multi-centered method, the 116 patients enrolled were assigned to the treated group (n = 60) and the control group (n = 56). The control group was treated by chemotherapy alone, while the treated group treated by chemotherapy combined with Chinese herbal medicine, i.e. Kangliu Zengxiao Decoction (KLZX) was administered in the chemotherapy stage, followed with Feiyanning Decoction (FYN) in the stage after ending the chemotherapy. The survival time, Karnofsky score, main clinical symptoms and adverse reactions, etc. were observed.
The median survival time was 15.57 months in the treated group, which was higher than that in the control group (11.17 months, P< 0.01). The improvements in tumor related symptoms such as fatigue, dyspnea, etc. in the treated group were better than those in the control group (P <0.05). In addition, adverse reactions such as leucopenia, digestive reaction (such as nausea and vomiting) in the treated group were less than those in the control group (P <0.05).
Chinese herbal medicine combined with chemotherapy shows favorable effect in improving quality of life and prolonging survival time on patients with advanced NSCLC.

[show abstract][hide abstract] ABSTRACT: The tumor stem cells (TSC) existing in the tumor plays a crucial role in carcinogenesis though very few in number. It is a special kind of stem cells with highly proliferative and self-regenerative cap ability to maintain its number stable and generate tumor. Therefore, the radical treatment of tumor should focus on TSC. TSC are derived from adult stem cells. According to TCM theory, normal stem cells belong to the category of Shen essence and qi, and patients suffering from malignant tumor always manifest as the syndrome of essence and qi deficiency, so nourishing Shen essence and qi should be of great importance for treatment of tumor.
