type="abstract" xml:lang="en"><p>Effective delivery of chemotherapeutic agents to tumors is a critical objective of improved cancer therapy. Traditional antiangiogenic therapy aims at eradicating tumor blood vessels, but the subsequently reduced blood perfusion may limit the drug amount delivered into the tumor and potentially lead to tumor hypoxia, which has been proved to be unable to meet the therapeutic expectations. “Shexiang Baoxin Pill” (SBP) is a well-known traditional Chinese medicine (TCM) used in clinical treatment of cardiovascular diseases, which has the pharmacological effect of pro-angiogenesis demonstrated recently. In this study, we disclosed our finding that SBP could enhance the effective treatment performance of gemcitabine (GEM) while minimizing the toxic side effects caused by GEM. Mechanistically, SBP increased tumor angiogenesis, blood perfusion, vascular permeability, and vessel dilation, which subsequently favored the delivery of GEM to the tumor lesion. Moreover, combined treatment with SBP and GEM could modify tumor microenvironment and consequently overcome multidrug resistance, and this combination therapy is also suitable for combination of SBP with some other chemotherapeutic drugs as well. These results suggest that combining SBP with chemotherapeutic agents achieves better treatment efficiency, which can open an avenue for expanding the combined treatment of anti-cancer chemotherapeutic drugs with TCM.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Abi Aad, S" uniqKey="Abi Aad S">S.

Traditional antiangiogenic therapy aims at eradicating tumor blood vessels, but the subsequently reduced blood perfusion may limit the drug amount delivered into the tumor and potentially lead to tumor hypoxia, which has been proved to be unable to meet the therapeutic expectations. “Shexiang Baoxin Pill” (SBP) is a well-known traditional Chinese medicine (TCM) used in clinical treatment of cardiovascular diseases, which has the pharmacological effect of pro-angiogenesis demonstrated recently. In this study, we disclosed our finding that SBP could enhance the effective treatment performance of gemcitabine (GEM) while minimizing the toxic side effects caused by GEM. Mechanistically, SBP increased tumor angiogenesis, blood perfusion, vascular permeability, and vessel dilation, which subsequently favored the delivery of GEM to the tumor lesion. Moreover, combined treatment with SBP and GEM could modify tumor microenvironment and consequently overcome multidrug resistance, and this combination therapy is also suitable for combination of SBP with some other chemotherapeutic drugs as well. These results suggest that combining SBP with chemotherapeutic agents achieves better treatment efficiency, which can open an avenue for expanding the combined treatment of anti-cancer chemotherapeutic drugs with TCM.</p></abstract><kwd-group><kwd>cancer treatment</kwd><kwd>Shexiang Baoxin Pill</kwd><kwd>combination therapy</kwd><kwd>vascular promotion</kwd><kwd>drug delivery</kwd></kwd-group><funding-group><award-group><funding-source id="cn001">National Natural Science Foundation of China<named-content content-type="fundref-id">10.13039/501100001809</named-content></funding-source></award-group><award-group><funding-source id="cn002">Science and Technology Commission of Shanghai Municipality<named-content content-type="fundref-id">10.13039/501100003399</named-content></funding-source></award-group></funding-group><counts><fig-count count="7"></fig-count><table-count count="1"></table-count><equation-count count="0"></equation-count><ref-count count="49"></ref-count><page-count count="12"></page-count><word-count count="6764"></word-count></counts></article-meta></front><body><sec sec-type="intro" id="s1"><title>Introduction</title><p>Anti-angiogenesis is a targeted therapeutic strategy and was once considered to be an effective treatment for cancers (Wu et al., <xref rid="B42" ref-type="bibr">2018</xref>). In the past decades, several drugs have been developed on promoting vascular regression and tumor starvation to inhibit tumor growth such as angiogenesis inhibitors, vascular disrupting agents and so on (Kong et al., <xref rid="B19" ref-type="bibr">2017</xref>). Nonetheless, the approach of eradicating tumor vasculature is not as effective as expected in that it may lead to odds of tumor hypoxia and drug resistance (Ebos et al., <xref rid="B9" ref-type="bibr">2009</xref>; El-Kenawi and El-Remessy, <xref rid="B10" ref-type="bibr">2013</xref>; Jain, <xref rid="B15" ref-type="bibr">2014</xref>). Interestingly, antiangiogenic treatment can reduce blood vessel density to some extent, leading to vascular temporary normalization and subsequently improving blood perfusion and releasing of chemotherapy drugs to tumor tissue as well as enhancing the efficacy of chemotherapeutics (Maes et al., <xref rid="B24" ref-type="bibr">2014</xref>). However, to reach this effectiveness, it requires the choice of optimal doses and time to use, otherwise, the tumor vasculature may close the therapeutic window due to its excessive suppression (Rolny et al., <xref rid="B29" ref-type="bibr">2011</xref>; Van der Veldt et al., <xref rid="B37" ref-type="bibr">2012</xref>). Thus, anti-angiogenic drugs are difficult to apply in clinical practice whether or not they are used alone or in combination with chemotherapeutic agents. Vascular disrupting agents aim at inducing tumor blood flow shutdown rapidly and selectively, resulting in massive necrosis (Siemann, <xref rid="B31" ref-type="bibr">2011</xref>). Nevertheless, they may potentially enhance tumor hypoxia and elevated tumor metastasis, thus failing to meet the therapeutic expectations (Palumbo et al., <xref rid="B26" ref-type="bibr">2011</xref>). Recent research has reported that promoting tumor angiogenesis and increasing blood flow would potentially improve the effectiveness of anti-tumor therapy (Bridges and Harris, <xref rid="B2" ref-type="bibr">2015</xref>; Villanueva, <xref rid="B38" ref-type="bibr">2015</xref>; Wong et al., <xref rid="B41" ref-type="bibr">2015</xref>, <xref rid="B40" ref-type="bibr">2016</xref>; Yin et al., <xref rid="B46" ref-type="bibr">2017</xref>). This strategy for treating tumors is radically different from the previous methods and is called “vascular promotion therapy” which at the best of our knowledge has been rarely studied so far.</p><p>Shexiang Baoxin Pill (SBP) is a common drug for chest pain or discomfort caused by coronary heart disease (CHD) in China, which is derived from the prescription of the ancient Suhexiang Pill recorded in Prescriptions of the Bureau of Taiping People's Welfare Pharmacy (Cen et al., <xref rid="B4" ref-type="bibr">2017</xref>; Fang et al., <xref rid="B11" ref-type="bibr">2017</xref>; Wei et al., <xref rid="B39" ref-type="bibr">2018</xref>). SBP is a traditional Chinese medicine preparation comprised of seven substances common components of Chinese medicine, including Moschus, Calculus Bovis, Radix Ginseng, Styrax, Cortex Cinnamomi, Venenum Bufonis, and Borneolum Syntheticum, the representative compounds and structures of each medicinal material are shown in <xref rid="T1" ref-type="table">Table 1</xref>. With the deepening of research, chemical fingerprinting and quantitative analysis of non-volatile and volatile compounds of SBP have been reported(Yan et al., <xref rid="B44" ref-type="bibr">2006</xref>). More than 70 non-volatile and 40 volatile compounds have been identified in SBP by using chromatography and mass spectrometry techniques (Liu et al., <xref rid="B21" ref-type="bibr">2015</xref>; Lv et al., <xref rid="B23" ref-type="bibr">2017</xref>). The potential active ingredients in Shexiang Baoxin Pills were analyzed by GC/MS and UPC2-MS/MS methods, the average content of which was: Muscone (65.54 μg/ml, 0.09%); Ginsenoside Re (41.22 μg/ml, 0.05%); Ginsenoside Rb1(151.94 μg/ml, 0.20%); Cinnamaldehyde (17.69 μg/ml, 0.02%); Cholic acid (75.08 μg/ml, 0.10%); Bufalin (31.07 μg/ml, 0.04%); Benzyl benzoate (278.46 μg/ml, 0.36%); Borneol (807.15 μg/ml, 2.0%) (Yan et al., <xref rid="B44" ref-type="bibr">2006</xref>, <xref rid="B43" ref-type="bibr">2009</xref>; Zhang et al., <xref rid="B49" ref-type="bibr">2018</xref>). Moreover, researchers used chromatographic-tandem mass spectrometry and plasma-based chemistry to screen potential bioactive components after oral SBP (Jiang et al., <xref rid="B16" ref-type="bibr">2009</xref>; Lu et al., <xref rid="B22" ref-type="bibr">2018</xref>). The relevant results indicate that there are four volatile components in the plasma after oral administration of SBP in rats, including isobornyls, borneol, musk ketone, and cinnamaldehyde (Chang et al., <xref rid="B5" ref-type="bibr">2014</xref>). Cinnamon aldehyde, a small molecule enriched in cinnamon, has been shown to be a potent vasodilator that activates transient receptor potential channels (TRPV1 and TRPA1) involved in nociception (Yanaga et al., <xref rid="B45" ref-type="bibr">2006</xref>; Szallasi et al., <xref rid="B34" ref-type="bibr">2007</xref>; Sui et al., <xref rid="B32" ref-type="bibr">2010</xref>). It induces angiogenic activity and accelerates wound healing (Yuan et al., <xref rid="B47" ref-type="bibr">2018</xref>). SBP can alleviate arterial obstructive disease by promoting angiogenic activity (Zhang et al., <xref rid="B48" ref-type="bibr">2017</xref>; Guo et al., <xref rid="B12" ref-type="bibr">2018</xref>). SBP confers enhanced angiogenic capacity to EPCs and is thought to be an agonist of angiogenesis by inducing expression of endothelial nitric oxide synthase (eNOS) and subsequent production of nitric oxide (NO) (Li et al., <xref rid="B20" ref-type="bibr">2015</xref>).</p><table-wrap id="T1" position="float"><label>Table 1</label><caption><p>Composition of Shexiang Baoxin Pill.</p></caption><table frame="hsides" rules="groups"><thead><tr><th valign="top" align="left" rowspan="1" colspan="1"><bold>Medicinal materials</bold></th><th valign="top" align="left" rowspan="1" colspan="1"><bold>Representative compounds</bold></th><th valign="top" align="left" rowspan="1" colspan="1"><bold>Representative compounds 2D structure</bold></th><th valign="top" align="left" rowspan="1" colspan="1"><bold>Therapeutic effects</bold></th></tr></thead><tbody><tr style="border-bottom: thin solid #000000;"><td valign="top" align="left" rowspan="1" colspan="1">Artificial moschus</td><td valign="top" align="left" rowspan="1" colspan="1"><bold>Muscone</bold></td><td valign="top" align="left" rowspan="1" colspan="1"><inline-graphic xlink:href="fphar-10-00565-i0001.jpg"></inline-graphic></td><td valign="top" align="left" rowspan="1" colspan="1">Promotes blood circulation and relieves blood stasis, alleviates pain, and subdues swelling.</td></tr><tr style="border-bottom: thin solid #000000;"><td valign="top" align="left" rowspan="1" colspan="1">Cortex cinnamomi</td><td valign="top" align="left" rowspan="1" colspan="1"><bold>Cinnamaldehyde</bold>, Cinnamic acid</td><td valign="top" align="left" rowspan="1" colspan="1"><inline-graphic xlink:href="fphar-10-00565-i0002.jpg"></inline-graphic></td><td valign="top" align="left" rowspan="1" colspan="1">Dilates blood vessels, stimulates angiogenesis, promotes blood circulation, and wound healing.

However, with the increasing dosage of the drug, its inherent severe side effects and adverse reactions unavoidably appeared (Katircibasi and Eken, <xref rid="B17" ref-type="bibr">2017</xref>), which limit the long-term clinical usage.</p><p>Therefore, we hypothesized that it could enhance the treatment performance of GEM in the presence of SBP, whilst minimizing the adverse effects. To validate this hypothesis, SBP combined GEM was tested in the treatment of Lewis lung carcinoma (LLC) tumor-bearing C57BL/6 mice in comparison with GEM alone to explore the anti-tumor effect <italic>in vivo</italic>. Following by that, the investigation of the effect of SBP on tumor vasculatures and tumor microenvironment was conducted, and changes of tumor angiogenesis, blood supply, vascular permeability, and tumor hypoxia degree were detected in mice treated with the combination of SBP and GEM afterwards. Next, the content of GEM in the tumor tissue was detected by High Performance Liquid Chromatography (HPLC) method.

In contrast, the suppressed effects of SBP (32 mg/kg)/GEM (35 mg/kg) and SBP (64 mg/kg)/GEM (35 mg/kg) were of significance, comparable to those of the GEM (200 mg/kg) group. These data suggest that SBP can improve the anti-tumor efficacy of GEM even at a lower dose of 32 mg/kg. Similar findings were observed both in tumor inhibition rates and morphology (<xref ref-type="fig" rid="F1">Figures 1B,C</xref>).

In the past few decades, many efforts have been made to reduce tumor vascular density in order to starving tumors. Unfortunately, this starving strategy may at the same time increase the level of tumor hypoxia and the possibility of drug resistance (Chen and Cleck, <xref rid="B6" ref-type="bibr">2009</xref>; Jain, <xref rid="B15" ref-type="bibr">2014</xref>). Inhibiting tumor vascular density and vascular function may be accompanied by limited drug delivery into tumor tissues, leading to failure to meet therapeutic expectations (Pavlidis and Pavlidis, <xref rid="B27" ref-type="bibr">2013</xref>). The primary goal of intensive chemotherapy is to improve the delivery of drugs in tumors and new methods were developed to achieve that goal by enhancing blood perfusion. This strategy for treating tumors is radically different from previous methods and is called “vascular promotion therapy” which has been rarely studied (Bridges and Harris, <xref rid="B2" ref-type="bibr">2015</xref>; Villanueva, <xref rid="B38" ref-type="bibr">2015</xref>; Wong et al., <xref rid="B41" ref-type="bibr">2015</xref>, <xref rid="B40" ref-type="bibr">2016</xref>;Yin et al., <xref rid="B46" ref-type="bibr">2017</xref>).</p><p>Cardiovascular diseases (CVD) and cancers remain the two leading causes of death in developed countries (Collaborators, <xref rid="B7" ref-type="bibr">2017</xref>). Due to common risk factors for these diseases, many patients suffered from both cancers and CVD (Suter and Ewer, <xref rid="B33" ref-type="bibr">2013</xref>). In addition, a number of tumor therapies are accompanied by the inherent cardiovascular toxicity, which may affect the prognosis and quality of life of cancer patients (Abi Aad et al., <xref rid="B1" ref-type="bibr">2015</xref>). Thus, it is of significance for paying attention to interference between the two treatments.</p><p>TCMs have been employed to treat various diseases thousand years ago, and their effectiveness has also been confirmed in the literature (Tang et al., <xref rid="B35" ref-type="bibr">2008</xref>). SBP is a famous TCM used for the treatment of cardiovascular diseases with a long history, which is composed of seven medicinal herbs with relative activities (Zhang et al., <xref rid="B48" ref-type="bibr">2017</xref>; Dong et al., <xref rid="B8" ref-type="bibr">2018</xref>). Recent reports suggest that this drug has pharmacological effects of anti-oxidation, endothelial protection and pro-angiogenesis efficiency (Li et al., <xref rid="B20" ref-type="bibr">2015</xref>; Zhang et al., <xref rid="B48" ref-type="bibr">2017</xref>; Guo et al., <xref rid="B12" ref-type="bibr">2018</xref>; Yuan et al., <xref rid="B47" ref-type="bibr">2018</xref>). Based on the above features of SBP, this drug was selected to be administered in combination with chemotherapeutic anti-cancer drugs in order to achieve synergistic effects.</p><p>Our <italic>in vivo</italic> results showed that the combination of SBP and GEM can actually improve cancer treatment efficiency and allow for lower doses of GEM to work as effectively as conventional higher doses. Then, in order to elucidate the mechanisms of this therapy, we focused on tumor angiogenesis. Our data demonstrated that by increasing tumor vascular density, blood perfusion, vascular permeability and tumor vessel dilation, co-used SBP could achieve better drug delivery efficiency. Furthermore, recent studies have shed light upon the critical role of tumor microenvironment for cancer progression, which is strongly correlated with cancer progression and chemoresistance (Martin et al., <xref rid="B25" ref-type="bibr">2016</xref>; Gupta et al., <xref rid="B13" ref-type="bibr">2017</xref>; Seleit, <xref rid="B30" ref-type="bibr">2017</xref>). Angiogenesis has been reported to help in reducing tumor hypoxia (Wong et al., <xref rid="B41" ref-type="bibr">2015</xref>). Angiogenesis is associated with modified tumor microenvironment, such as decreased tumor hypoxia and desmoplasia. We found that combining SBP and GEM enhanced oxygen supply and decreased the level of αSMA-positive myofibroblasts and collagen. Reducing toxic side effects is another important feature of enhancing tumor therapy. We showed that via enhancing the delivery and release of gemcitabine in tumors, we are able to minimize the adverse effects of the treatment whilst enhancing its efficacy. Finally, our data demonstrated that the combination of SBP and other chemotherapeutic agents can also improve the antitumor effect, suggesting that this treatment strategy could open a new way.</p></sec><sec sec-type="conclusions" id="s5"><title>Conclusion</title><p>In summary, our studies demonstrated that SBP could increase tumor angiogenesis, blood perfusion, vascular permeability and vasodilation, which facilitates the delivery of chemotherapeutic drugs to tumor (<xref ref-type="fig" rid="F7">Figure 7</xref>).
