Stresses induced by the deficiency or excess of trace mineral elements, such as manganese (Mn), represent a common limiting factor for the production of crops like Brassica napus. To identify key genes involved in Mn allocation in B. napus and elucidate the underlying mechanisms, a member of the metal tolerance protein (MTP) family obtained in the previous screening of cDNA library of B. napus under Mn stress was selected as the research subject. Based on the sequence information and phylogenetic analysis, it was named as BnMTP10. It belongs to the Mn-cation diffusion facilitator (CDF) subfamily. Expression of BnMTP10 in yeast significantly improved the tolerance of transformants to excessive Mn and iron (Fe) and reduced the accumulation of Mn and Fe. However, the yeast transformants exhibited no significant changes in tolerance to excess cadmium, boron, aluminum, zinc, or copper. The qRT-PCR results demonstrated that the flowers of B. napus had the highest expression of BnMTP10, followed by roots and leaves. Subcellular localization studies revealed that BnMTP10 was localized in the endoplasmic reticulum (ER). Compared with wild-type plants, transgenic Arabidopsis overexpressing BnMTP10 exhibited enhanced tolerance to excessive Mn stress but showed no significant difference under Fe stress. Correspondingly, under excessive Mn stress, the Mn content in the roots of transgenic Arabidopsis increased significantly. However, under excessive Fe stress, the Fe content in transgenic Arabidopsis did not alter significantly. According to the results, we hypothesize that BnMTP10 may alleviate excessive Mn stress in plants by mediating Mn transport to the ER. This study facilitated our understanding of efficient mineral nutrients, and provided theoretical foundations and gene resources for breeding B. napus.

This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Clinical trials play a crucial role in advancing the field of human health care. The registration of clinical trials can effectively identify potential publication bias and prevent unnecessary duplication of research efforts, serving as a source of transparent data for health care professionals and researchers, enhancing the quality of clinical research, and presenting more transparent, standardized, authentic, and useful clinical trials. To enhance the capacity for evidence production in traditional medicine from the source, the International Traditional Medicine Clinical Trial Registry (ITMCTR), a cross-regional registry focusing on the theme of traditional medicine, was established. Under the current registration background, this study aims to introduce the problems and current status related to clinical trial registration, as well as the features and functions of the ITMCTR. The results of this study illustrate the necessity of establishing a specialized registration platform for traditional medicine to assist researchers in understanding the basic background of registration and relevant information regarding registration platforms, regardless of whether their research is related to traditional medicine or not. Ultimately, the results of this work will help researchers choose the appropriate platform for more efficient and transparent registration.

Da Qinjiaotang is a common classical prescription for the treatment of stroke. It originates from Collection of Writings on the Mechanism of Disease， Suitability of Qi， and the Safeguarding of Life as Discussed in the Basic Questions （《素问病机气宜保命集》） by physician LIU Wansu， and is composed of Gentianae Macrophyllae Radix， Glycyrrhizae Radix et Rhizoma， Chuanxiong Rhizoma， Angelicae Sinensis Radix， Paeoniae Radix Alba， Asari Radix et Rhizoma， Notopterygii Rhizoma et Radix， Saposhnikoviae Radix， Scutellariae Radix， Gypsum Fibrosum， Angelicae Dahuricae Radix， Atractylodis Macrocephalae Rhizoma， Rehmanniae Radix， Rehmanniae Radix Praeparata， Poria， and Angelicae Pubescentis Radix. Doctors of all dynasties have disputed the composition principle of the prescription and argued whether its treatment of stroke belongs to the theory of "internal wind" or "external wind". Through collating and analyzing ancient and modern literature related to the indications of Da Qinjiaotang， this paper was dedicated to the origin of syndrome differentiation and treatment of Da Qinjiaotang. According to LIU Wansu's original works， Da Qinjiaotang is a prescription for the treatment of "internal wind"， and in the prescription， wind medicinal herbs such as Gentianae Macrophyllae Radix， Notopterygii Rhizoma et Radix and Angelicae Pubescentis Radix removes stagnation， clears sweat pore， and makes qi and blood channels flow smoothly. However， later generations， affected by the idea of "external wind"， believe that this prescription is used for the treatment of "external wind". Ancient physicians gradually supplemented the symptoms of stroke， such as wry eye and mouth， hemibody pain and limb numbness， which were treated by Da Qinjiaotang， and Da Qinjiaotang was also applied to the treatment of other diseases， such as tendon dryness， convulsion and arthralgia. Modern doctors still explain the disease pathogenesis from the theory of "external wind" as deficiency in channels and collaterals and the entry of pathogenic wind， and the prescription has the effect of dispersing wind， clearing heat and nourishing and activating blood. In clinical practice， Da Qinjiaotang is mainly used to treat cerebrovascular diseases and peripheral facial paralysis in nervous system diseases， gouty arthritis and rheumatic arthritis in the rheumatic immune system and skin diseases. The above findings facilitate the research and development of Da Qinjiaotang.

Transforming growth factor-β1 (TGF-β1) acts as a tumor promoter in advanced prostate cancer (PCa). We speculated that microRNAs (miRNAs) that are inhibited by TGF-β1 might exert anti-tumor effects. To assess this, we identified several miRNAs downregulated by TGF-β1 in PCa cell lines and selected miR-3691-3p for detailed analysis as a candidate anti-oncogene miRNA. miR-3691-3p was expressed at significantly lower levels in human PCa tissue compared with paired benign prostatic hyperplasia tissue, and its expression level correlated inversely with aggressive clinical pathological features. Overexpression of miR-3691-3p in PCa cell lines inhibited proliferation, migration, and invasion, and promoted apoptosis. The miR-3691-3p target genes E2F transcription factor 3 (E2F3) and PR domain containing 1, with ZNF domain (PRDM1) were upregulated in miR-3691-3p-overexpressing PCa cells, and silencing of E2F3 or PRDM1 suppressed PCa cell proliferation, migration, and invasion. Treatment of mice bearing PCa xenografts with a miR-3691-3p agomir inhibited tumor growth and promoted tumor cell apoptosis. Consistent with the negative regulation of E2F3 and PRDM1 by miR-3691-3p, both proteins were overexpressed in clinical PCa specimens compared with noncancerous prostate tissue. Our results indicate that TGF-β1-regulated miR-3691-3p acts as an anti-oncogene in PCa by downregulating E2F3 and PRDM1. These results provide novel insights into the mechanisms by which TGF-β1 contributes to the progression of PCa.

To explore the law and characteristics of adverse events of medical devices and to provide research methods and basis for reducing the recurrence of similar adverse events, we collect medical devices safety information from five representative countries in the world, and make statistics and analysis on the types of events, the types of management and the causes of events. The results show that among 136 serious adverse events, the top three causes of recall are product design factors, software factors, and component defects. In order to reduce the application risk of medical devices, it is suggested that product designers, operating users and medical institutions should correctly implement the monitoring and evaluation system of medical devices.
