Medicinal plants, with diverse species, high heterozygosity, and special breeding objectives, can be hardly bred with conventional hybridization techniques. Plant genetic transformation is highly selective and can specifically change the traits of plants, serving as an important technical means for the breeding of medicinal plants. The commonly used plant genetic transformation technologies include Agrobacterium-mediated transformation and particle bombardment. Agrobacterium-mediated transformation is the most widely used method, while it is not applicable to all medicinal plants due to the high specificity. Although not specific, particle bombardment is limited in application due to the low conversion efficiency and external force damage to cells and tissue. With the rise and development of nanotechnology, the emerging nanomaterial-mediated transformation has solved the problems of the above two technologies. However, limited by its late development, the mechanism of nanomaterial-mediated introduction of genetic materials into plant cells remains unclear, and thus this technology is rarely used in medicinal plants. This article summarizes the development status of several commonly used or emerging plant genetic transformation technologies such as Agrobacterium-mediated transformation, particle bombardment, and nanomaterial-mediated transformation, as well as their application in different medicinal plants. Furthermore, this article looks forward to the development trend of genetic transformation technologies for plants and their application prospects in medicinal plants and Chinese materia medica resources, aiming to provide new technical ideas for the genetic improvement and germplasm innovation of medicinal plants and inject new impetus into the sustainable development of Chinese materia medica resources.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovitis as its pathological basis. Although current therapeutic drugs can alleviate symptoms, they are often accompanied by a high risk of side effects. In recent years, the use of flavonoids from traditional Chinese medicine (TCM) in the treatment of RA has garnered significant attention. Studies have shown that the mechanisms by which flavonoids treat RA include inhibiting the release of pro-inflammatory factors, regulating multiple cellular signaling pathways, alleviating oxidative stress, modulating immune system functions, inhibiting bone destruction, and suppressing angiogenesis. Due to their notable anti-inflammatory, antioxidant, and immunomodulatory activities, flavonoids hold promise as potential therapeutic agents for RA. A substantial number of articles in this field have been published. By reviewing Chinese and international literature and applying bibliometric and visual analysis using CiteSpace, this paper explored research hotspots and frontiers in this field, systematically reviewed the structures and anti-RA mechanisms of TCM flavonoids, provided a theoretical basis for their use in RA treatment and clinical applications, and offered new perspectives and references for the discovery of novel TCM-based anti-RA drugs.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

ObjectiveTo observe the effectivenss and safety of Yiqi Huoxue Formula (益气活血方) combined with surgery and sequential therapy of estrogen and progesterone for the treatment of intrauterine adhesion with syndrome of qi deficiency and blood stasis. MethodsSixty-four patients with intrauterine adhesions were recruited in Guang'anmen Hospital, China Academy of Chinese Medical Sciences during 1st June 2021 to 31st December 2022, and they were randomly divided into two groups, with 32 patients in each group, all receiving transcervical resection of adhesions (TCRA). The control group was treated with sequential therapy of estrogen and progesterone after surgery, taking 1 tablet orally daily, estradiol tablets for the first 14 days, and estradiol dydrogesterone tablets for the last 14 days. In the treatment group, the postoperative treatment was combined with Yiqi Huoxue Formula on the basis of the treatment in the control group, and 1 dose was taken daily. The treatment course of both groups was 3 months. We observed the clinical effectiveness, syndrome scores of traditional Chinese Medicine (TCM), endometrial thickness, uterine adhesion score, menstrual flow points, and the re-adhesion rate and pregnancy rate 3 months after the end of treatment of the two groups, and conducted evaluation on safety. ResultsThe total clinical effectiveness rates of the treatment group and the control group were 90.63% and 75.00%, respectively, significantly better in the treatment group (P<0.05). The endometrial thickness and menstrual flow of patients in both groups increased after treatment, and the scores of uterine adhesion and TCM syndrome scores decreased significantly (P<0.05 or P<0.01). After treatment, the uterine adhesion score and TCM syndrome scores of the treatment group decreased significantly compared with the control group (P<0.05). The 6-month postoperative pregnancy rate in the treatment group was 37.50%, higher than the 12.50% in the control group (P<0.05). The re-adhesion rate was 3.13% in the treatment group and 9.38% in the control group, and the difference between the two groups was not statistically significant (P>0.05). No adverse events occurred in both groups. ConclusionYiqi Huoxue Formula combined with surgery and sequential therapy of estrogen and progesterone for treating intrauterine adhesion patients with syndrome of qi deficiency and blood stasis can promote endometrial recovery, increase menstrual flow, improve patients' clinical symptoms, and improve pregnancy rate, showing certain clinical effectiveness and safety.

Zedoary turmeric oil, volatile oil extracted from zedoary turmeric, composed mainly of monoterpenes (including α-pinene, β-pinene, etc.) and sesquiterpenes (including β-elemene, zedoary alcohol, zedoary ketone, etc.), and has been used in clinical practice to treat various malignant tumors such as ovarian cancer, cervical carcinoma, colorectal cancer, lung cancer and liver cancer. Zedoary turmeric oil regulates vascular endothelial growth factor and nuclear factors- κB, signal transducers and activator of transcription 3 signaling pathways to play a role in inhibiting tumor angiogenesis, inhibiting tumor cell proliferation, inducing tumor cell apoptosis, and blocking cell cycle. However, due to its insolubility in water and poor stability, its clinical application is limited; the application of new formulations and technologies such as liposomes, microspheres, and nanoemulsion improves the solubility and stability of zedoary turmeric oil. This paper summarizes recent research progress on the chemical composition, anti-tumor effects, and formulations of zedoary turmeric oil, both domestically and internationally, providing a reference for further expanding the clinical application and formulation development of zedoary turmeric oil in the anti-tumor field.
