Introduction
Lung cancer is now one of the malignant tumors with the highest mortality rate in the world.According to the statistical results released by the World Natural Health Fund and the Global Cancer Research Institute by 2020, the incidence rate ranks second [1].According to cytological classification, lung cancer can be further subdivided into the following two types, namely, primary small cell lung cancer (SCLC) and primary nonspecific small cell lung cancer (NSCLC) of which the incidence of NSCLC can be as high as about 85% or more [2].Lung adenocarcinoma is one of the most commonly used human histological subtypes in the diagnosis of NSCLC [3].The clinical manifestations of early symptoms of lung adenocarcinoma are mostly insidious.The early clinical manifestations of lung adenocarcinoma are relatively insidious, while in the middle and advanced stages, local invasion or distant metastasis occurs, and its treatment effect is poor, and the estimated 5-year survival rate is only 18% [4].At present, the main treatment methods for lung adenocarcinoma are targeted and immunotherapy [5][6][7].Although this therapy has achieved certain clinical efficacy, the population with clinical benefit is still very small [8,9], and it is not a small number of patients.The 5-year survival rate of patients with lung cancer after treatment is still low (about 20%) [10].Therefore, there is an urgent need to improve the living conditions of patients and improve the survival rate.
Shishiwei Wendan Decoction is made by Professor Zhu Jinzhong based on Wendan Decoction and combined with his many years of clinical experience.The functions of Ophiopogon japonicus, Solanum lyratum, Acorus tatarinowii Schott, Polygala Radix, Rehmannia glutinosa, and Salvia chinensis [11] are soothing the liver and invigorating the spleen and regulating triple energizer.Yuan Zhu Zhenheng pointed out in "Danxi Heart Method: Phlegm Thirteen": "Mortal people who have lumps in the middle and lower parts of the body are mostly phlegm," and the abnormal flow of body fluids will produce phlegm, dampness, and drinking.Therefore, it can be considered that the tumor is caused by the abnormal distribution of body fluids.According to "Lingshu•Benshu," "Shaoyang belongs to the kidney, and the upper part of the kidney is connected to the lung, so the two are stored."Among them, the author believes that Shaoyang refers to the gallbladder and the three energizers of Shaoyang, and the Shisiwei Wendan Decoctiom can solve the above problems, Shisiwei Wendan decoction is added on the basis of Wendan Tang.To understand the function of Shisiwei Wendan decoction, we must first understand its basic prescription-Wendan Decoction was first recorded in the book."Three Causes Extreme Disease Syndrome Volume Nine Deficiency Syndrome Treatment" is the name of the book.recorded Shisiwei Wendan decoction: "after the treatment of serious illness, virtual annoyance can not sleep, this gallbladder cold death, this medicine is the main."This is inherited from Wendan decoction, which is the inheritance of Wendan decoction.Although Wendan decoction is called "warming gallbladder," but in fact, the treatment focuses on clearing gallbladder and stomach, and its symptoms are more obvious in Zhongjiao, so the most important drugs are regulating qi and resolving phlegm and clearing gallbladder and stomach.Pinellia pinellia is the core medicine of Shiniwei Wendan Decoction; it eliminates dampness and phlegm and treats tumor diseases, etc. Bamboo Ru and Pinellia ternata match, not only resolving phlegm and stomach but also clearing gallbladder heat, making gallbladder and stomach harmonious; Chen Pi Liqi Huatan invigorates spleen dryness and dampness; Fructus Aurantii breaks qi accumulation, resolves phlegm, and dispels ruffian; Poria cocos invigorates the spleen and tranquilizes the heart ; licorice Yiqi and middle reconcile various medicines.All kinds of medicines are used together to regulate qi and resolve phlegm, clear gallbladder and stomach, eliminate annoyance, and stop vomiting.Shisiwei Wendan decoction is developed by Professor Zhu Jinzhong on the basis of Wendan decoction and combined with his own clinical experience for many years.In clinical application, it can significantly reduce cough and pain in patients with lung adenocarcinoma.In view of the complex active ingredients in this compound, the current mechanism of Shishiwei Wendan Decoction in the treatment of lung adenocarcinoma is still unclear, and this study was aimed at clarifying the molecular mechanism of its treatment of lung adenocarcinoma.
Network pharmacology is an emerging discipline in recent years.It is a systematic analysis method based on the interaction of diseases, drugs, active ingredients, target genes, and target proteins.The complex synergistic functions and associations also coincide with the notable features of the holistic treatment of modern Chinese medicine and the systemic synergistic treatment of drugs in the treatment of disease processes [12], which can more clearly and intuitively represent the system of the drug itself and its related compounds.The use of network pharmacology can more clearly and intuitively show the complex synergistic relationship between the drug itself and the compound [13,14].To this end, this study is aimed at studying the main drugs and their active chemical constituents, traditional Chinese medicine Shishiwei Wendan Decoction used in the treatment of primary lung adenocarcinoma through the technical system of modern network pharmacology technology and drug molecular information docking.The potential target structure and molecular information pathway provide the basis for the further research and development of the safety of the traditional Chinese medicine Shishiwei Wendan Decoction and the evaluation of the clinical use of the drug.

Discussion
In this study, the active components and drug targets of fourteen traditional Chinese medicines were predicted by using the online database to predict the disease targets of lung adenocarcinoma, such as Pinellia, Zhuru, and Citrus aurantium, and the following results and conclusions were obtained by bioinformatics analysis: firstly, the active components of all traditional Chinese medicines and their corresponding drug targets of Shishiwei Wendan Decoction were obtained using TCMSP, ETCM, and TCMID databases, and a total of 384 drug targets were obtained.Then, the OMIM, GeneCards and DisGeNET databases were used to obtain the disease targets of lung adenocarcinoma, and a total of 7680 disease targets were obtained.Through the intersection of drug targets and disease targets, a total of 284 key targets were obtained.The functional enrichment analysis results showed that the key target genes were related to biological processes such as the response to nutrient levels, the response to drugs, and the regulation of fat metabolism.It is significantly related to molecular functions such as drug binding, peptide binding, vitamin binding, and amide binding and cellular components such as membrane region, secretory granule cavity, cytoplasmic vesicle cavity, and membrane microregion.In addition, key   In this study, the main active components of Shishiwei Wendan Decoction against lung adenocarcinoma were preliminarily screened by the method of network pharmacology.Experimental studies have found that quercetin can not only reduce the proliferation rate and invasive ability of lung adenocarcinoma cells and promote the apoptosis of A549 cells but also affect tumor progression by increasing the expression of miR-16 and inhibiting the expression of claudin-2 [15,16].Chuancheng Pi can significantly reduce the G0/G1 phase cells of A549 cells and reduce the recurrence rate of lung cancer cells.The G2/M phase is blocked, and the proliferation of tumor cells from the cell cycle is inhibited from entering the apoptosis program, thereby effectively improving the development of tumors [17].According to Liu et al., the inhibitory effect of TNF-α affects the expression of Raf-1 and Bcl-2 and then promotes the apoptosis of lung cancer NCI-H460 cells.Yue [19] showed that naringenin has obvious proliferation inhibition and apoptosis promotion effects on A549 cells, and the reaction mechanism may be related to the activation of ROS/P38-MAPK pathway.
The key targets of Shishiwei Wendan Decoction are hsp90aa1, AKT1, MAPK1, MAPK3, and TP53.The hypoxic microenvironment is widespread in tumors, and the Hsp90 pathway, PI3K-Akt signaling pathway, and MAPK signaling pathway are all closely related to the HIF-1 signaling pathway.Studies have found that the phosphatidylinositol 3kinase (PI3K)/Akt signaling pathway, the upstream pathway of HIF-1, is involved in the regulation of angiogenesis, pro-liferation, invasion, metastasis, and apoptosis of general tumor cells under hypoxic conditions.The prognosis of cancer patients is closely related [20].The study found that quercetin can reverse the cisplatin resistance of human A549 lung adenocarcinoma cells by inhibiting EMT and weakening apoptosis through PI3K/Akt pathway [21].In addition, experiments have shown that some cancer cells can promote the formation and survival of endothelial cell tubes through PI3K/Akt signal pathway, thus changing the microenvironment, which is conducive to tumor growth.This provides a reference for targeted treatment of lung adenocarcinoma [22].The Hsp90 pathway is a cooperative pathway of HIF-1.Some scholars believe that the binding of Hsp90 to the b HLH-PAS domain of HIF-1α under hypoxia can activate HIF-1α, indicating that Hsp90 activity has an activating effect on HIF-1α [23].The MAPK pathway includes several key signaling components and phosphorylation events that play a role in tumorigenesis.These activated kinases transmit extracellular signals that regulate cell growth, differentiation, proliferation, apoptosis, and migration functions, due to receptor tyrosine kinases.Abnormal activation of amino acid kinases or gain-of-function mutations, mainly in RAS or RAF genes, lead to alterations in the RAS-RAF-MEK-ERK-MAPK (RAS-MAPK) pathway in human cancers [24].Stutvoet et al. found that the activity of MAPK pathway plays a key role in the expression of PD-L1 in lung adenocarcinoma induced by EGF and IFN γ, However, MAPK pathway does not change the targeted genes, so MAPK may be a target to improve the efficacy of immunotherapy [25].The extracellular regulated protein kinase (ERK) transduction pathway is the main transduction pathway in the MAPK signaling pathway, and its  BioMed Research International downstream can also regulate HIF-1.ERK is mainly activated by the abnormally activated Ras target Raf, which in turn activates The phosphorylation of downstream mitogen extracellular kinase (MEK) eventually activates ERK.When stimulated by, for example, mitogen receptors, cytokines, and growth factors, ERK is phosphorylated and then transduced.It enters the nucleus and activates a variety of oncogenes one after another through transcriptional regulation and induction [26].
The research group found that the expression of PRKCZ-AS1 positively regulates the expression of MAPK1 by consulting the literature.Similarly, the expression of MAPK1 is negatively regulated by miR-766-5p expression.Moreover, the binding ability between miR-766-5p and MAPK1 was confirmed.In addition, the knockdown of MAPK1 partially saved the promoting effect of miR-766-5p inhibition on the proliferation and migration of PRKCZ-AS1-transfected lung adenocarcinoma cells.Overall, PRKCZ-AS1 promotes the development of lung adenocarcinoma by upregulating the expression of MAPK1 through spongy miR-766-5p [27].AKT is a serinethreonine kinase that is overactivated in many cancers, including lung cancer.Using the transgenic mouse model of lung tumorigenesis driven by overexpression of IGF-IR, it was found that the deletion of Akt1 could inhibit the development of lung tumor, while the deletion of Akt2 enhanced the development of lung tumor.Lung tumors that develop without Akt2 are less likely to show discrete nodules and show scattered growth patterns more frequently.RNA sequencing revealed many differentially expressed genes in lung tumors lacking Akt2, among which five genes Actc1, Bpifa1, Mmp2, Ntrk2, and Scgb3a2 were associated with human lung cancer [28].TP53 mutation is one of the most common mutations in early lung adenocarcinoma (LUAD), which can cause a series of changes in the immune landscape, progression, and clinical outcome of early LUAD.Zeng et al. took the mutant group as a reference.There were significant differences in somatic mutation mRNA-seq miRNA-seq immune infiltration and immunomodulator in patients with mutant LUAD suggesting that TP53 mutation plays a key role in the occurrence and development of lung adenocarcinoma [29].
Then, using Cytoscape (version 3.8.2) to construct the drug-active ingredient key target regulatory network and PPI network, we further counted the degrees, and the top 5 key target genes were TP53, HSP90AA1, MAPK1, MAPK3, and AKT1.Finally, we extracted five key targets and their corresponding active molecules, downloaded protein crystal structures and small molecule 3D structures, and performed molecular docking experiments.The experimental results show that the binding energies of the core components and key targets in Shishiwei Wendan Decoction are all <-5 kcal•mol-1, indicating that there is a strong binding ability between the key target proteins and the drug-active small molecules.
Based on the above analysis, we screened the key targets of all drugs in Shishiwei Wendan Decoction for the treatment of lung adenocarcinoma using an online database.The purpose of this study was to clarify the molecular mech-anism of Shishiwei Wendan Decoction in the treatment of lung adenocarcinoma and to provide a theoretical basis and reference value for Shishiwei Wendan Decoction in the treatment of lung adenocarcinoma.
