Esophageal cancer ranks the seventh and sixth in morbidity and mortality among the malignant tumors， respectively. In traditional Chinese medicine， toxic medicinals are commonly used to enhance the efficacy on esophageal cancer. In recent years， as natural drugs have become the focus of research on anti-tumor drugs， toxic Chinese medicinals have received wide attention. It has been found that a variety of toxic Chinese medicinals have significant anti-esophageal cancer effect. In this study， articles on the treatment of esophageal cancer were retrieved from SinoMed， China National Knowledge Infrastructure （CNKI）， Wanfang Data， and VIP， and the toxic Chinese medicinals in the articles were summarized. It was found that the toxic Paridis Rhizoma， Gekko， Cremastrae Pseudobulbus Pleiones Pseudobulbus， Scolopendra， Hirudo， Sophorae Tonkinesis Radix et Rhizoma， Scorpio， and Bufonis Corium were mainly used for the treatment of this cancer. They can be classified into the heat-clearing and toxin-removing medicinals， toxin-counteracting medicinals， phlegm-resolving medicinals， and blood-activating and stasis-resolving medicinals. Most of them were pungent （19，52.78%） or bitter （17，47.22%）. The majority had the meridian tropism toward liver （25， 69.44%）， spleen （13， 36.11%）， and lung （12， 33.33%）. According to the research on the above commonly used toxic Chinese medicinals， most of them have anti-tumor effect and some have been reported to have anti-esophageal cancer effect. The mechanism is mainly the inhibition of proliferation. To be specific， they exert the anti-cancer effect by suppressing the proliferation， migration， and differentiation of cancer cells， inducing cell cycle arrest， and activating B-cell lymphoma/leukemia-2 （Bcl-2）-associated X protein （Bax）/Bcl-2/Caspase signaling pathway to induce apoptosis. In this paper， the commonly used toxic Chinese medicinals for the treatment of esophageal cancer were statistically analyzed， and the mechanisms were summarized， in order to provide a reference for the clinical rational use of toxic Chinese medicinals and the research on the mechanisms for their efficacy.

Esophageal squamous cell carcinoma （ESCC）， the predominant histological strain of esophageal cancer in China， is complex in pathogenesis and may be associated with mutations in several genes and dysregulation of the mitogen-activated protein kinase （MAPK） pathway， the phosphatidylinositol 3-kinase （PI3K） pathway， etc. MAPK signaling pathway can be activated by growth factors， proto-oncogenes， and oxidative stress， thus participating in biological functions such as cell proliferation， differentiation， migration， and apoptosis. More evidence shows that the MAPK signaling pathway plays an important role in the occurrence and development of ESCC and is expected to become an effective target for the treatment of ESCC. The classical MAPK family consists of extracellular signal-regulated kinases 1/2 （ERK1/2）， c-Jun N-terminal kinases 1/2/3 （JNK1/2/3）， p38 α/β/γ/δ， and extracellular signal-regulated kinase 5 （ERK5）. Each pathway consists of three cascade sequentially phosphorylated and activated protein kinase systems. The activation of the ERK1/2 pathway is related to the proliferation， migration， drug resistance， and apoptosis inhibition of ESCC. JNK， p38， and ERK5 pathways seem to show bidirectional regulation， and there is signal integration between MAPK internal pathways. Chemotherapeutic drugs for esophageal cancer often have side effects and are prone to drug resistance， so it has become a new idea to find effective and low-toxic drug alternatives. Studies have found that flavonoids， terpenoids， alkaloids， saponins， phenols， and other active ingredients in Chinese medicine can play an anti-ESCC effect by targeting the MAPK pathway， which is mainly reflected in inhibiting proliferation， migration， and invasion， inducing cycle arrest， promoting apoptosis， reversing drug resistance， etc. Therefore， this paper reviewed the regulatory role of the MAPK signaling pathway in ESCC and the research progress in active ingredients of Chinese medicine in regulating MAPK pathway against ESCC to provide references for the mechanism research and new drug development of Chinese medicine in the prevention and treatment of esophageal cancer.

ObjectiveTo investigate the mechanism of Baitouweng Tang in inhibiting the growth of esophageal cancer （EC） cells by regulating budding uninhibited by benzimidazoles 1 （BUB1）/signal transducer and activator of transcription 3 （STAT3） signaling pathway. MethodGene chip technology was used to explore the differential gene expression between esophageal cancer tissues and normal tissues and identified differentially expressed genes. The differentially expressed genes were analyzed by bioinformatics methods. EC cells were treated with 25， 50， 100， 200， 400， 800 mg·L^-1 Baitouweng Tang. EC cell viability was detected by Thiazolyl Blue （MTT） colorimetry. Cell cycle and apoptosis were measured by flow cytometry. The expression of BUB1 was measured by real time quantitative polymerase chain reaction （Real-time PCR）. The protein levels of BUB1， STAT3， phosphorylated （p）-STAT3， Cyclin B1 （CCNB1）， cyclin-dependent kinase 1 （CDK1）， B-cell lymphoma-2 （Bcl-2）， cysteinyl aspartate-specific proteinase（Caspase）-3， and Caspase-9 were measured by Western blot. The migration and invasion abilities of the cells were measured by wound-healing and Transwell invasion assays. ResultDifferentially expressed genes were primarily involved in biological processes， signaling pathways， and network construction related to cell mitosis， with BUB1 identified as a key core gene. Compared with the control group， Baitouweng Tang inhibited BUB1 expression （P<0.05，P<0.01）. In vitro experiments showed that compared with the control group， Baitouweng Tang could significantly inhibit the growth （P<0.05，P<0.01）， migration and invasion （P<0.05，P<0.01） of EC cells， induce apoptosis （P<0.05，P<0.01）， and cause G₂/M phase increase （P<0.01）. After treatment with Baitouweng Tang， compared with the results in the control group， the expression of Caspase-3， and Caspase-9 in EC cells increased significantly （P<0.05，P<0.01）， while the expression of Bcl-2， BUB1， CCNB1， and CDK1 decreased significantly （P<0.05，P<0.01）. Moreover， the STAT3 signaling pathway was also found to play an important role in this process. ConclusionBaitouweng Tang may inhibit the growth of EC cells by downregulating BUB1 and mediating the STAT3 signaling pathway.
