ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription （BSZY） on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group （Control）， a model group （Model）， low-dose BSZY （BSZY-L）， medium-dose BSZY （BSZY-M）， and high-dose BSZY （BSZY-H） groups （2.57， 5.14， 10.28 g·kg^-¹）， and a Zishen Yutai Pill （ZSYT） group （1.575 g·kg^-¹）. Hematoxylin-eosin （HE） staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of estrogen （E₂）， progesterone （P）， luteinizing hormone （LH）， prolactin （PRL）， and follicle-stimulating hormone （FSH） in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform （TCMSP） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP） v2.0 databases， while disease targets for recurrent spontaneous abortion （RSA） were retrieved from GeneCards， DrugBank， Online Mendelian Inheritance in Man （OMIM）， and Therapeutic Target Database （TTD）. The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor （ERα）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） and explore its protective mechanism on RSA rats. ResultsCompared with the control group， the model group exhibited significantly decreased uterine， ovarian， and embryonic wet weights （P<0.05， P<0.01）， with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles， primary follicles， mature follicles， and corpora lutea， along with a large number of atretic follicles. The endometrium was thinner， and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast， compared with the model group， the BSZY groups at all doses and the ZSYT group demonstrated increased uterine， ovarian， and embryonic wet weights， along with a reduced abortion rate. The number of primordial follicles， primary follicles， mature follicles， and corpora lutea increased， while atretic follicles decreased. The endometrium thickened， and decidual tissue displayed normal cellular structure with tight arrangement. Additionally， the model group showed significantly decreased levels of E₂， P， PRL， and FSH in serum （P<0.05， P<0.01）， along with a decreasing trend in LH level. In contrast， the BSZY groups at all doses exhibited significantly elevated levels of E₂， P， LH， PRL， and FSH in serum （P<0.05， P<0.01）. Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα， PI3K， and p-Akt proteins （P<0.05， P<0.01）. ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome， possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function， thereby lowering the abortion rate.

Traditional Chinese medicine(TCM) resources are the essential material foundation for the development of TCM. The national survey of TCM resources serves as a periodic summary of these resources, ensuring the continuity, prosperity, and development of TCM in China. Since 1949, four national surveys of TCM resources have been conducted. The fourth survey incorporated an investigation into traditional knowledge related to TCM resources, including the traditional medicinal knowledge of Chinese ethnic minorities, with the goal of systematically exploring, preserving, and inheriting this knowledge. This manuscript provides an overview of the basic findings from the first three national surveys of TCM resources, while also clarifying the concepts, categories, forms, carriers, and acquisition pathways of traditional knowledge related to TCM resources. A preliminary summary of the findings from traditional knowledge investigations reported in current literature is also presented. Based on the fourth survey, this manuscript emphasizes the urgency of developing public medical knowledge through empirically-based investigations, the excavation, and compilation of traditional knowledge. It also outlines the potential for conducting "precise" investigations based on first-hand data obtained from the survey, as well as facilitating the discovery and evaluation of new medicines using traditional knowledge related to ethnic minority medicinal practices. This manuscript is expected to provide valuable insights for promoting the health and industrial development of ethnic minority populations in the post-"survey" phase.

“Deficiency cause， cold accumulation， and qi stagnation” originates from Essentials from the Golden Cabinet （《金匮要略》）， which is a guiding principle for the pathogenesis of women's diseases， pioneering the differentiation and treatment of women's diseases based on patterns， and having a profound influence on future generations. Following the classical principles and simplifying the complexities， this paper explored the pathogenesis and mechanism of polycystic ovary syndrome （PCOS） from the perspective of “deficiency cause， cold accumulation， and qi stagnation”， and believed that depletion of essence and blood， long-term accumulation of internal cold， and qi constraint and blood stasis are the causes of PCOS， with depletion of essence and blood， and lack of nourishment of zang-fu （脏腑） organs as the root， and cold pathogen invasion， qi constraint and blood stasis as the branch. The main treatment principle is “treating deficiency with supplementation”， and dispelling pathogen while reinforcing healthy qi， along with “treatment of cold by warming” and “treatment of stagnation by dispersing”. This is of great significance for the treatment of polycystic ovary syndrome. Clinically， these methods can be used flexibly to guide treatment and formula selection for PCOS， with the goal of harmonizing qi and blood and regulating menstruation.

Objective:To explore therapeutic efficacy and mechanism of puerarin(PUE)in treating of ulcerative colitis(UC).Methods:Network pharmacology and molecular docking technique were used to screen and analyze targets of PUE in regulating UC.C57BL/6 mice were given free access to 2.5%DSS aqueous solution for 7 days,and influence of PUE on changes in body weight and disease activity index(DAI)score were subsequently observed.Histopathological alterations of colon tissue were observed by HE staining,changes of goblet cell population in colon tissue were evaluated through Alcian blue staining;expressions of inflammatory factors in colon tissue were detected by qRT-PCR and ELISA.Effect of PUE on MODE-K cell viability and apoptosis were assessed by CCK-8 and flow cytometry.Results:A total of 38 common targets of PUE in modulating UC,such as AKT1,TNF,STAT3,CASP3,HIF1A and etc,mainly involving TNF,IL-17 and PI3K-Akt signaling pathway.In vivo experiments confirmed that PUE ameliorated degree of colon shortening,body weight and DAI scores and reduced inflammatory cell infiltration in mice.Besides,expressions of inflammatory factors in colon,such as TNF-α and IL-1β,were inhibited by PUE.Furthermore,in vitro experiments validated that PUE relieved DSS-induced apoptosis of epithelial cells.Conclusion:PUE alleviates occurrence and development of DSS-induced UC in mice.

The main sources of natural drugs include various biological species such as plants, animals, and microorganisms. The accurate identification of these species is the bedrock of natural drug development. We propose a novel method of species identification in this paper: analysis of whole-genome (AGE), a molecular diagnostic method used to identify species by finding species-specific sequences from the whole genome and precisely recognizing the specific target sequences. We elaborate that the principle for species identification based on AGE is that the genome sequences of diverse species must differ and divide the implementation strategy of the method into two levels of research and application. Based on our analysis of its characteristics, the method would have the potential advantages of reliable principle, high specificity, and wide applicability. Moreover, three crucial concerns related to building method systems including genome acquisition, bioinformatics analysis, and database construction, are further discussed. In summary, we offer theoretical underpinnings and methodological guidance for the development of bioinformatics software and commercial kits, indicating AGE has great application potential in objects, subjects, and industries.

Imported medicinal materials are an important part of Chinese medicinal resources. To be specific, about 10% of the around 600 commonly used Chinese medicinal materials are from abroad, and the introduction of foreign medicinal materials has promoted the development of Chinese medicine. Amid the advancement of reform and opening up and the "Belt and Road" Initiative, major headway has been made in the cross-border trade in China, bringing opportunities for the import of medicinal materials from border ports. However, for a long time, there is a lack of systematic investigation on the types of exotic medicinal materials at border ports. In the fourth national census of traditional Chinese medicine resources, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, together with several organizations, investigated the nearly 40 border ports, Chinese medicinal material markets, and border trade markets in 6 provinces/autonomous regions in China for the first time and recorded the types, sources, circulation, and the transaction characteristics of imported medicinal materials. Moreover, they invited experts to identify the origins of the collected 237 medicinal materials. In addition, the status quo and the problems of the medicinal materials were summarized. This study is expected to lay a basis for clarifying the market and origins of imported medicinal materials as well as the scientific research on and supervision of them.

Based on plant species databases, species lists and literature records, general situation of the Chinese medicinal endemic plant (vascular plant) has been systematically summarized, and its quantity and distribution characteristics of Chinese medicinal endemic plants are presented in this paper. The results showed that 3 150 endemic species are Chinese medicinal plants belonging to 785 genera in 153 families, which includes 38 species of 22 genera in 12 families of pteridophyta, 42 species of 14 genera in7 families of gymnosperms, and 3 070 species of 749 genara in 134 families of angiosperms. The top four families involving medicinal endemic species are Asteraceae (218 species), Ranunculaceae (182 species), Labiatae (151 species), and Liliaceae (133 species). The top four provincial administration distributed medicinal endemic species are Sichuan (1 568 species), Yunnan (1 533 species), Guizhou (955 species) and Hubei (930 species).On the regional scale, the most abundant one is the southwest region (2 465 species), followed by the central region (1 226 species) and the northwest region (949 species). Localization characteristics for domestication and artificial cultivation of medicinal endemic species are more prominent due to their narrower and limited distribution areas, indicating it is possible for these species acting as local potential resource for reasonable economic development.

OBJECTIVETo evaluate the genetic diversity among wild germplasm resources of Coix that distributed at altitude of 550-1550 m in Xishuangbanna, Yunnan province by comparing the morphological variation, biological and economical factors.

METHODThe field plot experiments were conducted to observation the germination rate, growth period. While the milled rice rate, content of protein, crude fat and ethanol extract of 9 wild Coix germplasm resources were measured.

RESULTThe germination rate of 9 germplasm was from 22% to 81%, and the growth period was among 139-156 d, which belongs to the medium-late mature type. The germination rate, growth stage, plant height, leaf length and width, tiller number, ramification number, seed number per stem of 9 Coix germplasm were significantly different (P < 0.05), respectively. The range of seed total protein contents were from 15.63% 25.74%, crude fat contents were from 5.05%-7.14%, and the contents of alcohol extract, which showed antitumor activity, were from 5.85%-7.27%.

CONCLUSIONThe fact of quite different in plant morphological, biological and quality characters of 9 germplasm suggested that the genetic diversity in the wild populations of Coix distributed throughout the regions of Xishuangbanna is relatively abundant.
