    Abstract Ethnopharmacological relevance: The Yi people in the Xiaoliangshan region in southwest China have a unique practice of combining ritual treatment and traditional medicine to care for patients. Despite increasing urbanization in the area, they have managed to preserve their distinctive lifestyle and extensive knowledge of traditional medicinal plants, setting them apart from other regions. However, there is a lack of systematic documentation on the knowledge of traditional medicinal plants used by the Yi people in Xiaoliangshan.
    Aim of the study: This research aims to achieve the following objectives: 1. Document the diversity of medicinal plants used by the Yi people and explore their therapeutic usages. 2. Evaluate and analyze the main types of diseases with a high incidence in the local area and identify the types of medicinal plants used to treat these diseases. 3. Explore the underlying geographical and human factors influencing both disease prevalence and medicinal plant usage.
    Methods: Ethnobotanical research methods were used to record and analyze the medicinal plants used by the Yi in Xiaoliangshan. Experts identified all plant specimens collected during ethnobotanical field surveys. The types of diseases treated by medicinal plants were classified according to the International Classification of Primary Care -
    Results: A total of 125 medicinal plants were recorded after interviewing 193 participants. Of the medicinal plants identified, those with over 100 use reports were Paris polyphylla (202 use reports), Taxillus sutchuenensis (183), Artemisia indica (149), and Papaver somniferum (113). A total of 14 disease categories were recorded, with those related to the following categories having higher Informant Consensus factor values (ICF ≥0.85): Pregnancy, Childbearing, Family Planning, General and Unspecified, Urological, Respiratory, Musculoskeletal, and Skin. The highest quantity of medicinal plants is utilized to improve specific diseases and health problems, namely those related to Digestion, Skin, and Musculoskeletal. Fewer plant species were utilized for diseases or health issues associated with Eyes, Psychological, or Pregnancy, Childbearing, and Family Planning. The use reports from the informants also revealed how some medicinal plants are used to treat a variety of diseases or health issues. For instance, Malva pusilla is used for inducing abortion, treating postpartum hemorrhage, and joint sprains; Artemisia indica is used for treating malaria; Argentina lineata is used to remedy tuberculosis and malaria. Taxillus sutchuenensis is used for dealing with cold, pneumonia, and other ailments.
    Conclusions: The Yi people in Xiaoliangshan have a rich knowledge of traditional medicinal plants. Decoction and wine brewing are the most common processing methods used for these plants, which are utilized to treat a wide range of diseases. The characteristics of the medicinal use of the Yi people reflects the alpine mountainous environment in which they live, and their medical practices are closely related to traditional healing culture. This study enhances our understanding of the Yi traditional medicine via documentation and offers a valuable reference for future research and the development of new drugs.

    Abstract Background: Folk plant nomenclature is a part of knowledge of indigenous people often used to distinguish plant species. This study aimed to document the folk botanical nomenclature of the Yi people in Xiaoliangshan, Yunnan Province, which has not been systematically investigated to date. The results of this study will assist in conserving biodiversity and the language of the Yi people and will promote the transmission of ethnobotanical knowledge.
    Methods: An ethnobotanical survey of plants used by the Yi people in Xiaoliangshan, Yunnan Province, was conducted from September 2019 to August 2021. Semi-structured interviews and key informant interviews were conducted to collect and document ethnobotanical information, which was then used to analyse the folk botanical nomenclature of the Yi people. In addition, the folk names of plants used by the Xiaoliangshan Yi community were compared with those of the Yi people living in the Daliangshan, where the environment is considerably different.
    Results: In this study, 266 informants were interviewed, and the names of 228 indigenous plants were extracted from 3088 use reports. The nomenclature used by the local Yi people is based on plant characteristics, plant habitat, plant use, and the local culture. By comparing the folk plant names of the Yi people in Xiaoliangshan with those of the Yi people in Daliangshan, we found that the plant names of the two places have some similarities and also with their own unique characters. The important folk plant names of the Yi people in Xiaoliangshan usually have a monosyllable non-binomial structure or have and "divine attributes" in their names.
    Conclusions: The Yi people in Xiaoliangshan have a rich and diverse knowledge of plant naming determined by cultural, and environmental factors. The botanical nomenclature of the Yi people has distinct rules and characteristics, and the plant naming directly includes important plants that they believe to be used and protected, which is of great significance to the protection of biodiversity.

    Abstract Objective: The present study aims to analyze the clinical effect of the Qing Yi Tiao Mian (QYTM) formula on unexplained recurrent spontaneous abortion (URSA) during early pregnancy and the immune balance of T lymphocytes.
    Methods: With their consent, 45 patients with URSA in weeks 4-9 of pregnancy were separated into three groups, i.e., the conventional fetal protection (n = 15), prednisone treatment (n = 10), and QYTM formula treatment (n = 20) groups. These patients received treatment once they had been diagnosed with an intrauterine pregnancy. The conventional fetal protection group was given progesterone (20 ∼ 40 mg daily injection) for four weeks. The prednisone treatment group was given progesterone (20 ∼ 40 mg daily injection) + prednisone (5 mg/d) for four weeks. The QYTM formula treatment group was given progesterone (20 ∼ 40 mg daily injection) + QYTM formula (one dose per day) for four weeks. In addition, women who had previously had a normal pregnancy were enrolled as a control group (n = 18). The success rate of the pregnancy in the first trimester was observed in each group, and the proportion of T lymphocytes in the peripheral blood before and after treatment was recorded.
    Results: Among the 20 patients with URSA in the QYTM formula treatment group, 19 remained pregnant. Thus, the success rate during early pregnancy was 95%, which was significantly higher than the conventional fetal protection (53.33%) and prednisone treatment (70%) groups. The CD8+ T and natural killer (NK) cells population in the URSA groups was higher compared with the control group (P < 0.01). The QYTM formula treatment significantly decreased the ratio of CD8+ T lymphocytes (P < 0.01) and NK cells (P < 0.01).
    Conclusion: The QYTM formula significantly decreased the spontaneous abortion rate in patients with URSA during early pregnancy. The mechanism may be closely related to the inhibition of the killer lymphocytes' proliferation by CD8+ T lymphocytes and NK cells.

    Abstract Focal segmental glomerulosclerosis (FSGS) is a common clinical condition with manifestations of nephrotic syndrome and fibrosis of the glomeruli and interstitium. Yi-Shen-Hua-Shi (YSHS) granule has been shown to have a good effect in alleviating nephrotic syndrome (NS) in clinical and in animal models of FSGS, but whether it can alleviate renal fibrosis in FSGS and its mechanism and targets are not clear. In this study, we explored the anti-fibrotic effect and the targets of the YSHS granule in an adriamycin (ADR)-induced FSGS model and found that the YSHS granule significantly improved the renal function of ADR-induced FSGS model mice and also significantly reduced the deposition of collagen fibers and the expression of mesenchymal cell markers FN, vimentin, and α-SMA in the glomeruli of ADR-induced FSGS mice, suggesting that the YSHS granule inhibited the fibrosis of sclerotic glomeruli. Subsequently, a network pharmacology-based approach was used to identify the potential targets of the YSHS granule for the alleviation of glomerulosclerosis in FSGS, and the results showed that the YSHS granule down-regulated the expressions of BMP2, GSTA1, GATS3, BST1, and S100A9 and up-regulated the expressions of TTR and GATM in ADR-induced FSGS model mice. We also proved that the YSHS granule inhibited the fibrosis in the glomeruli of ADR-induced FSGS model mice through the suppression of the BMP2/Smad signaling pathway.

    Abstract Objective: The purpose of this study is to reveal the mechanism of action of Yi Qi Tong Qiao Pill (YQTQP) in the treatment of allergic rhinitis (AR), as well as establish a paradigm for the researches on traditional Chinese medicine (TCM) from systematic perspective. Methods: Based on the data collected from TCM-related and disease-related databases, target profiles of compounds in YQTQP were calculated through network-based algorithms and holistic targets of TQTQP was constructed. Network target analysis was performed to explore the potential mechanisms of YQTQP in the treatment of AR and the mechanisms were classified into different modules according to their biological functions. Besides, animal and clinical experiments were conducted to validate our findings inferred from Network target analysis. Results: Network target analysis showed that YQTQP targeted 12 main pathways or biological processes related to AR, represented by those related to IL-4, IFN-{\gamma}, TNF-{\alpha} and IL-13. These results could be classified into 3 biological modules, including regulation of immune and inflammation, epithelial barrier disorder and cell adhesion. Finally, a series of experiments composed of animal and clinical experiments, proved our findings and confirmed that YQTQP could improve related symptoms of AR, like permeability of nasal mucosa epithelium. Conclusion: A combination of Network target analysis and the experimental validation indicated that YQTQP was effective in the treatment of AR and might provide a new insight on revealing the mechanism of TCM against diseases.

    Abstract Background: The Yi ethnic group is the sixth largest minority in China. The aim of this study was to investigate dental caries status among Yi preschool children in the Yunnan province, China.
    Method: This cross-sectional study invited 5-year-old Yi children using multistage cluster sampling. Two trained and calibrated dentists examined the children in kindergartens. The children's dental caries experience was assessed using the decayed, missing, and filled teeth (dmft) index. Visual plaque on an indexed tooth of each six sextants was recorded and the oral hygiene status was assessed using the Visible Plaque Index. Parents completed questionnaires that surveyed their educational attainment. The questionnaires also collected information about the children's demographics, snacking habits, oral-health-related behaviors and dental visit experiences. The associations between caries experiences and potential factors were analyzed using zero-inflated negative binomial regression.
    Results: All 452 invited children (249 boys, 55%) participated in this study with a response rate of 100%. Dental caries prevalence rate was 83%. The mean dmft score and decayed teeth score were 5.2 ± 4.4 and 5.1 ± 4.4, respectively. Almost half of the children (n = 211, 47%) had visible plaque on four or more of the six sextants. Most (n = 366, 81%) of the children had not visited a dentist in the prior 12 months. Regression analysis found the children's caries experience was associated with their dental visit experience.
    Conclusion: The great majority of the Yi preschool children experienced dental caries and almost all of the cavities were not restored. Their oral hygiene was poor and visible plaque was commonly found on their teeth.
