ObjectiveTo investigate the mechanism of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis extract （ASH） in treating Parkinson's disease （PD） in mice by Data-Independent Acquisition （DIA） proteomics. MethodsThe α-Synuclein （α-Syn） transgenic PD mice were selected as suitable models for PD， and they were randomly assigned into PD， ASH （61.25 mg·kg^-1）， and Madopar （97.5 mg·kg^-1） groups. Male C57BL/6 mice of the same age were selected as the control group， with eight mice in each group. Mice were administrated with corresponding drugs by gavage once a day for 20 days. The pole climbing time and the number of autonomic activities were recorded to evaluate the exercise ability of mice. Hematoxylin-eosin staining was employed to observe neuronal changes in the substantia nigra of PD mice. Immunohistochemistry （IHC） was employed to measure the tyrosine hydroxylase （TH） activity in the substantia nigra and assess the areal density of α-Syn in the striatum. DIA proteomics was used to compare protein expression in the substantia nigra between groups. IHC was utilized to validate key differentially expressed proteins， including Lactotransferrin， Notch2， Ndrg2， and TMEM 166. The cell counting kit-8 （CCK-8） method was used to investigate the effect of ASH on the viability of PD cells with overexpression of α-Syn. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the protein and mRNA levels of Lactotransferrin， Notch2， Ndrg2， and TMEM 166 in PD cells. ResultsCompared with the control group， the model group showed prolonged pole climbing time， diminished coordination ability， reduced autonomic activities （P<0.01）， and reduced swelling neurons. Compared with the model group， ASH and Madopar reduced the climbing time， increased autonomic activities （P<0.01）， and ameliorated neuronal damage. Compared with the control group， the model group showed a decrease in TH activity in the substantia nigra and an increase in α-Syn accumulation in the striatum （P<0.01）. Compared with the model group， the ASH group showed an increase in TH activity and a reduction in α-Syn accumulation （P<0.05）. DIA proteomics revealed a total of 464 differentially expressed proteins in the model group compared with the control group， with 323 proteins being up-regulated and 141 down-regulated. A total of 262 differentially expressed proteins were screened in the ASH group compared with the model group， including 85 proteins being up-regulated and 177 down-regulated. Kyoto encylopedia of genes and genomes （KEGG） pathway analysis indicated that ASH primarily regulated the Notch signaling pathway. The model group showed up-regulation in protein levels of Notch2， Ndrg2， and TMEM 166 and down-regulation in the protein level of Lactotransferrin compared with the control group （P<0.01）. Compared with the model group， ASH down-regulated the protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.05） while up-regulating the protein level of Lactotransferrin （P<0.01）. The IHC results corroborated the proteomics findings. The cell experiment results showed that compared with the control group， the modeling up-regulated the mRNA and protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.01）， while down-regulating the mRNA and protein levels of Lactotransferrin （P<0.01）. Compared with the model group， ASH reduced the mRNA and protein levels of Notch2， Ndrg2， and TMEM 166 （P<0.01）， while increasing the mRNA and protein levels of Lactotransferrin （P<0.05， P<0.01）. ConclusionASH may Synergistically inhibit the Notch signaling pathway and mitigate neuronal damage by down-regulating the expression of Notch2 and Ndrg2. Additionally， by up-regulating the expression of Lactotransferrin and down-regulating the expression of TMEM166， ASH can address brain iron accumulation， intervene in ferroptosis， inhibit mitophagy， and mitigate reactive oxygen species damage， thereby protecting nerve cells and contributing to the treatment of PD.

In recent years, the research on the anti-tumor effect of traditional Chinese medicine has been increasing year by year. Both the effective extracted ingredients of Chinese medicine and its compound preparations have significant efficacy and advantages in tumor treatment. Costunolide, the active ingredient of Aucklandia lappa (a traditional Chinese medicine), is a natural sesquiterpene lactone, which has a variety of pharmacological effects, such as anti-oxidation, anti-inflammation, hypoglycemic effect, anti-microbial effect etc. In recent years, more and more experimental studies in vivo and in vitro have shown that this component has anti-tumor activity, which can inhibit the growth of breast cancer, gastric cancer, melanoma cancer, prostate cancer, leukemia, liver cancer, lung cancer, ovarian cancer, esophageal cancer, colorectal cancer, osteosarcoma and other tumors. Its antitumor mechanism mainly lies in the regulation of PI3K/AKT/mTOR, AKT-MDM 2-p53, ROS-AKT/GSK-3β, Bcr / Abl, Stat5 and other signaling pathways, which affects reactive oxygen species, apoptosis-related proteins, autophagy-related proteins, and cyclin, and thus induces apoptosis, causes autophagy and arrests cell cycle in G2 / M phase, G1 phase, and S phase. In addition, the combination of costunolide with imatinib and doxorubicin can attenuate toxicity and enhance anti-tumor effect, and also reverse tumor drug resistance. By consulting and sorting out the relevant research literature at home and abroad, the author summarized the research progress of costunolide on the antitumor effect and mechanism, the combined drug use and the reversal of tumor drug resistance in order to provide theoretical basis for the development and utilization of new drugs of this ingredient.

Based on the higher requirements of the complex maritime battlefield environment for medical support under the new circumstances, this article carried out the task analysis of medical service provided by the large warship as a maritime medical treatment platform. The article introduced the overall architecture of a China’s dock landing ship (LSD) and its current deployment scheme of medical resources, reviewed the current development in China and other countries of LSD fulfilling the mission of maritime medical support, and put forward the assumption of an LSD taking the mission of maritime medical support as a level-2 medical platform. Furthermore, the article discussed and demonstrated the ship’s capacity of medical service and the demand for medical support when it was used as a medical treatment platform from two aspects, i. e., the scope of medical treatment and the deployment of medical resources, with a view to providing scientific basis and theoretical support for carrying out "capacity-based" training with full complement of personnel and equipment in real combat conditions.
