Neuroblastoma (NB) is one of the most common malignant solid tumors in children, ranks fourth in the incidence of pediatric tumors, and accounts for 15% of pediatric tumor deaths in children in China. Despite the development of new treatment options, the prognosis for high-risk patients is still poor. An animal model that can replicate the tumorigenesis of NB is an important tool for the prevention and treatment of NB. However, there are currently no animal models that can simulate all features of human NB. To provide a reference for the construction of animal models and treatment of NB, this article introduced several animal models of NB that have been extensively researched: the mouse, chick embryo chorioallantoic membrane, and zebrafish models. At the same time, it elaborated on the species, construction methods, characteristics, advantages and disadvantages, and research progress in NB.

Ulcerative colitis（UC）is a disease characterized by chronic persistent inflammation of the colorectal mucosa. Its complex pathological mechanism is related to immune inflammation and enhanced apoptotic activity. The Janus kinase（JAK）/signal transducer and activator of transcription（STAT）is an important regulatory pathway in the body's physiological function, which can regulate the release of intestinal pro-inflammatory factors and induce apoptosis, resulting in colon tissue damage. In the condition of UC, the biological activities and expression levels of JAK and STAT increased, and the tissue inflammatory response and apoptosis rate increased, which led to the destruction of intestinal mucosal tissues. At present, in the treatment of UC, glucocorticoids and immunosuppressants are mainly employed to reduce intestinal inflammation. Although they can block the progress of UC to some extent, the adverse reactions are severe. A large number of studies have shown that traditional Chinese medicine（TCM） has significant advantages in the prevention and treatment of UC and can significantly reduce the recurrence rate of this disease. In recent years, plenty of studies have been carried out to explore the role of TCM in the treatment of UC by regulating the JAK/STAT pathway. The results have shown that the JAK/STAT pathway is the key target pathway of TCM in the treatment of UC. Based on the etiology and pathogenesis of deficiency and excess, TCM regulates the JAK/STAT pathway by clearing heat, drying dampness, cooling and activating blood, invigorating the spleen, warming the kidney, and performing both tonification and elimination to maintain the balance between pro-inflammatory factors and anti-inflammatory factors, weaken colonic inflammatory response, inhibit apoptosis, and play a role in the treatment of UC. The present study analyzed the mechanism and effect of TCM in intervening in UC by targeting the JAK/STAT signaling pathway and summarized the molecular mechanisms of different cytokines such as interleukin-6（IL-6）, IL-10, IL-23, microRNA（miRNA）-146a, and suppressors of cytokine signaling 2/3（SOCS2/3） on many family subtypes of the JAK/STAT signaling pathway to facilitate the comprehensive understanding of researchers on the mechanism of TCM on the JAK/STAT pathway in UC, which is expected to provide a theoretical basis for the treatment of UC and further drug development.

ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study. MethodHepG2 cells were treated with M36 at different concentrations （0， 2， 4， 6， 8， 10 μmol·L^-1）. Firstly， the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium （MTT）， colony formation assay， and EdU proliferation assay. Hoechst staining， flow cytometry analysis， and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally， Western blot was used to detect protein expression of cancer-related signaling pathways. ResultCompared with the blank group， M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells （P<0.01）， and the half inhibitory concentration （IC₅₀） value of M36 for 48 h was 5.03 μmol·L^-1， in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L^-1 M36 for 48 hours， the apoptosis rate of HepG2 cells was （42.03±9.65）% （P<0.01）. Compared with the blank group， HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase （cleaved-PARP） protein levels （P<0.01）. Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h compared with the blank group （P<0.01）， which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ （LC3 Ⅱ）. Western blot results showed that compared with the blank group， the levels of phosphorylated extracellular regulated protein kinase （p-ERK）， phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）， phosphorylated c-Jun N-terminal kinase （p-JNK）， and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group （P<0.05， P<0.01）. The mechanism may be related to the up-regulation of MAPK signaling pathway. ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy， which may be related to the activation of the MAPK signaling pathway.
