ObjectiveTo explore the changes in color, odor and chemical components during wine-processing of Chuanxiong Rhizoma(CR), identify differential markers, and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis(PLS-DA), principal component analysis(PCA), discriminant factor analysis(DFA) and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models, and differential components were screened out based on variable importance in the projection(VIP) value1. Then, high performance liquid chromatography(HPLC) was employed to detect the content changes of four components(ferulic acid, senkyunolide I, senkyunolide A and ligustilide) during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L*(brightness value), a*(red-green value) and b*(yellow-blue value). Based on chromaticity differences, the color reference ranges were established for moderately processed CR, including L* of 46.75-48.24, a* of 5.37-6.07 and b* of 20.32-21.70. In odor analysis, DFA revealed significant differences among processing stages, and 11 odor markers were identified, with four differential markers(4-hydroxy-3-butylphthalide, isopropyl butyrate, L-limonene and 1-methoxyhexane) based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection, with discrimination accuracy rates of 92.4% and 93.272% for color and odor, respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages, and four differential components were screened out, providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

As a pivotal strategy to alleviate the shortage of organ donors, xenotransplantation has achieved remarkable advances in both pre-clinical and clinical studies in recent years, driven by continuous optimization of gene modification techniques and immunosuppressive regimens. Nevertheless, clinical translation still confronts formidable challenges, including rejection and heightened infection risks, which severely compromise long-term graft survival. Consequently, the role of immunosuppressive regimens in xenotransplantation has become increasingly prominent. This article summarizes the mechanisms underlying xenogeneic immune rejection, the latest developments in immunosuppressive regimens, cutting-edge strategies for inducing immune tolerance and the major hurdles facing clinical xenotransplantation. It delves into potential optimization strategies and directions for future clinical research, aiming to offer theoretical insights and practical guidance for the safe and effective application of clinical xenotransplantation.

Objective:
To understand the prevalence of myopia among primary and secondary school students in minority areas of Yunnan Province, and to explore the influence of outdoor activities and short-distance use of eyes, so as to provide a basis for early myopia intervention.
Methods:
In October 2020, the survey was conducted among 1 782 primary and secondary school students in three cities of Yunnan through a multi stage random cluster sampling method. All subjects underwent a questionnaire survey and the visual acuity examination at baseline. The first follow-up was conducted in October 2021 to obtain 1 691 valid samples, and the second follow-up was conducted in May 2023 to obtain 1 367 valid samples. Factors associated with myopia among primary and secondary school students were explored by using generalized estimating equations.
Results:
The prevalence rates of myopia in 2020, 2021 and 2023 were 52.64%, 61.62% and 69.35%, respectively, showing an increasing trend ( χ 2 trend =91.77, P <0.05). The results of multivariate regression analysis on the generalized estimation equations showed that age at baseline ( OR =1.31), girls ( OR =1.76), Hani ethnicity ( OR =0.75), Bai ethnicity ( OR =0.69), parental myopia ( OR =1.97-2.29), parents often reducing children s exercise time for homework or tutoring ( OR =1.35), less than 1 time or 2-3 times of ball sports per week ( OR =1.27, 1.20 ), reading and writing in the classroom during the break ( OR =1.27), reading in direct sunlight occasionally ( OR =1.20), using only desk lamp for writing at home ( OR =0.71), more than 1 hours of short-distance eye use for a break once ( OR =1.23) were associated with myopia among primary and secondary school students ( P <0.05).
Conclusions
Outdoor activities and short-distance use of eye among primary and middle school students in minority areas in Yunnan province are suboptimal. Enhancing the related environmental and behavioral factors can effectively mitigate the occurrence and progression of myopia.
