Introduction. Traditional Chinese medicine (TCM) believes that the pathogenic factors of colorectal cancer (CRC) are “deficiency, dampness, stasis, and toxin,” and Fuzheng–Jiedu Decoction (FJD) can resist these factors. In this study, we want to find out the potential targets and pathways of FJD in the treatment of CRC and also explain from a scientific point of view that FJD multidrug combination can resist “deficiency, dampness, stasis, and toxin.” Methods. We get the composition of FJD from the TCMSP database and get its potential target. We also get the potential target of colorectal cancer according to the OMIM Database, TTD Database, GeneCards Database, CTD Database, DrugBank Database, and DisGeNET Database. Subsequently, PPI analysis, KEGG pathways analysis, and GO biological processes analysis were carried out for the target of FJD in the therapy of colorectal cancer. In addition, we have also built a relevant network diagram. Results. In this study, we identified four core compounds of FJD in the therapy of colorectal cancer, including quercetin, kaempferol, beta-sitosterol, and stigmasterol. At the same time, we also obtained 30 core targets, including STAT3, INS, TP53, VEGFA, AKT1, TNF, IL6, JUN, EGF, CASP3, MAPK3, MAPK1, MAPK8, SRC, IGF1, CCND1, ESR1, EGFR, PTEN, MTOR, FOS, PTGS2, CXCL8, HRAS, CDH1, BCL2L1, FN1, MMP9, ERBB2, and JAK2. FJD treatment of colorectal cancer mainly involves 112 KEGG pathways, including FoxO (hsa04068) signaling pathway, PI3K-Akt (hsa04151) signaling pathway, HIF-1 (hsa04066) signaling pathway, T cell receptor (hsa04660) signaling pathway, and ErbB (hsa04012) signaling pathway. At the same time, 330 GO biological processes were summarized, including cell proliferation, cell apoptosis, angiogenesis, inflammation, and immune. Conclusions. In this study, we found that FJD can regulate cell proliferation, apoptosis, inflammation and immunity, and angiogenesis through PI3K-Akt signaling pathway to play an anti-CRC effect.

1. Introduction while 15 to 25 percent of CRC patients will be found with liver metastasis after radical surgery [3, 4]. At present, the Colorectal cancer (CRC), as the third most common cancer main treatment methods for CRC include radiotherapy and in the world, accounts for the fourth highest cancer mortality chemotherapy, surgery, targeting, and immunotherapy rate in the world [1]. It is a common malignant tumor of the [5, 6]. Because of its limitations, these treatments present the digestive tract. Most patients’ colorectal cancer is caused by whole body toxicity, drug resistance, low selectivity, low their old age and unhealthy lifestyle, and only a few of them efficacy, and other adverse reactions [7]. ,erefore, we want are caused by genetic factors. Other causes of colorectal to find a more effective and less toxic method against CRC cancer may include chronic inflammation of the gut, [8]. overweight, smoking, excessive intake of processed foods, Herbal medicine and traditional medical practice have and inadequate exercise [2]. In the diagnosis, due to the lack been reported as a world upsurge by the World Health of effective clinical screening biomarkers, early symptoms of Organization’s global Atlas of traditional, complementary, CRC are difficult to find. 15 to 25 percent of colorectal cancer and alternative medicine [9]. Traditional Chinese medicine patients have had liver metastasis at the time of detection, (TCM) has been used by the Chinese for thousands of years. 2 Evidence-Based Complementary and Alternative Medicine

In the early stage, we an- have pharmacological effects. ,erefore, it is necessary to alyzed the literature and data mining of the experience of five screen the pharmacokinetics of each compound of Chinese batches of national famous experts in traditional Chinese herbal medicine [21]. Based on the previously reported medicine (500 in each batch, 3000 in total) and three sessions model, we screened various compounds in FJD according to of Chinese Medicine Masters (30 students each, a total of 90 the pharmacokinetic absorption (A), distribution (D), people) in the treatment of CRC. At the same time, we found metabolism (M), and excretion (E) parameters. Based on the the combination of the Fuzheng–Jiedu Decoction (FJD). FJD previous literature and the information in the relevant consists of Panax ginseng C.A. Mey (“RenShen” in Chinese, Chinese herbal medicine database, we selected natural RS), Pinellia ternata (“BanXia” in Chinese, BX), and Smilacis compounds with oral bioavailability (OB) greater or equal to Glabrae Rhizoma (“TuFuLing” in Chinese, TFL). Not only 30 percent and drug sensitivity (DL) greater or equal to 0.18 does the drug combination have a good antitumor effect, but for further analysis [22] (Supplementary file 1). also it can improve the symptoms of CRC such as asthenia and abdominal distension [13]. Based on the theory of TCM, the compatibility of FJD can not only treat “deficiency, 2.3. Get the Target Protein of the Selected Compounds.

EGF binds with EGFR, thus activating cancer cells [30]. Beta-sitosterol is one of the most abundant the epidermal growth factor receptor, activating PI3K/Akt phytosterols in the diet, comparable to animal cholesterol pathway, and finally promoting tumor proliferation [36, 37].
