ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material, covering aspects such as nomenclature, origin, geographical distribution, harvesting and processing methods, quality assessment, therapeutic effects and indications, by consulting ancient herbal texts, medical compendia, and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty, with Zhuli being the standard name used throughout history, alongside aliases like Zhuzhi, Zhuyou and Huoquan. Historically, the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis(Danzhu), although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou(present-day Chengdu and surrounding areas in Sichuan) and the Wuling region(between present-day Hunan, Guangdong, Guangxi and Jiangxi provinces), while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally, Bambusae Succus was harvested from bamboo that had grown for exactly one year, today, it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation, whereas modern industrial production employs dry distillation, reflux extraction, and percolation. In terms of quality evaluation, ancient texts considered a sweet taste to be superior, while today, clarity and transparency are prioritized. Historically, Bambusae Succus was characterized as sweet and cold nature, targeting the lung and stomach meridians, with uses evolving from clearing heat and resolving phlegm to nourishing Yin, moistening dryness, and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet, bitter, and cold in nature, affecting the heart, liver, and lung meridians, with functions including clearing heat, resolving phlegm, and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion, lung heat with phlegm congestion, convulsions, epilepsy, excessive phlegm in febrile diseases, high fever with thirst, irritability during pregnancy, and tetanus, with more clearly defined applications. Based on the results of the research, it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus, the one-year-old Phyllostachys nigra var. Henonis, which has been highly praised throughout history, should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore, in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste, and reasonable modern quality control standards should be established.

By consulting ancient and modern literature, this article systematically reviews and verifies the historical evolution of the herbal medicine known as Baijiang across various dimensions, including name, origin, scientific name verification, medicinal parts, production area, quality, harvesting and processing, as well as its nature, taste, and therapeutic effects, in order to provide a reference for the development and utilization of famous classical formulas containing Patriniae Herba. Patriniae Herba has a long history of use. It derives its name from the distinctive musty odor of its roots, which resembles spoiled soy sauce. However, due to its alias Kucai, there has been much confusion with other plants. Since the Ming dynasty, various plants have been used interchangeably as Baijiang. Herbal textual research showed that Patriniae Herba was first recorded in Shennong Bencaojing, and throughout history, Baijiang has been recognized as its standard name, though it has also been known by alternative names such as Luchang, Lujiang, and Suanyi. The main sources used throughout the ages were Patrinia scabiosaefolia or P. villosa, which is consistent with the 1977 edition of the Pharmacopoeia of the People's Republic of China. However, while the roots were traditionally used medicinally, the whole plant is now more commonly used in modern practice. In addition, the whole plants of Thlaspi arvense from the Cruciferae family and Sonchus brachyotus from the Compositae family are commonly used as regional substitutes for Baijiang. According to ancient records, Patriniae Herba was primarily found in Jiangxia(present-day eastern Hubei province) and Jiangdong(the region south of the lower reaches of the Yangtze River), but modern literature shows that it is distributed throughout the country without a distinct geographical origin. In ancient times, the roots were harvested in August and sun-dried, today, the whole plant is typically dug up in summer or autumn and sun-dried. In recent times, the quality has been summarized as being best when the roots are long, the leaves are abundant and green, and the aroma is strong. Regarding the processing, ancient methods often involved baking(drying over fire), while modern methods typically involve removing impurities, washing, and then cutting and drying the segments. The effects of Patriniae Herba are to clear heat and detoxify, eliminate blood stasis and drain pus. During the Han and Northern and Southern dynasties, it was used to treat skin diseases caused by heat, abscesses, postpartum diseases, and rheumatism, during the Five dynasties period, its therapeutic applications expanded to include diseases of the five senses, and by the modern era, conditions such as neurasthenia and insomnia were added. Regarding its properties and taste, it was recorded as bitter and neutral during the Han dynasty. By the Tang dynasty, it was slightly cold, with a taste of acrid and bitter. During the Yuan and Ming dynasties, it was mostly slightly cold and neutral, with a bitter and salty taste. In the Qing dynasty and modern times, it was mostly bitter and neutral, and in contemporary times, it has evolved to a taste of acrid, bitter, and cool. Based on the results of this study, it is recommended that when developing and utilizing famous classical formulas containing Patriniae Herba, one should select the entire herb of the historically mainstream sources, P. scabiosaefolia or P. villosa from the Valerianaceae family, and choose the processing method according to the prescription requirements. It is recommended to use raw products without specific requirements.

Objective To explore the independent risk factors for early failure of internal mammary artery grafts after coronary artery bypass grafting (CABG), and to construct and preliminarily evaluate a risk prediction model for the decline of internal mammary artery bridges, optimizing postoperative risk stratification and management strategies for patients. Methods Patients who underwent CABG at Fuwai Hospital, Chinese Academy of Medical Sciences from January 2016 to January 2020 were retrospectively enrolled. The primary endpoint was the failure of the internal mammary artery bridge one year after surgery, and the secondary endpoint was major adverse cardiac and cerebrovascular events (MACCE) within five years after surgery, including all-cause death, myocardial infarction, stroke, and revascularization. Patients were divided into a failure group and a non-failure group based on whether there was early failure of the internal mammary artery bridge after surgery. Independent risk factors for the failure of the internal mammary artery bridge were explored through the least absolute shrinkage and selection operator regression and multivariate logistic regression, and a failure risk prediction model was constructed and cross-validated. Patients were stratified for MACCE risk according to the total score of independent risk factors, and the 5-year cumulative MACCE-free rate was drawn using the Kaplan-Meier method. Results A total of 657 patients were included, among whom there were 54 patients in the failure group, including 38 males and 16 females, with an average age of (61.85±8.03) years; there were 603 patients in the non-failure group, including 467 males and 136 females, with an average age of (60.45±8.23) years. Multivariate logistic regression analysis showed that non-left main lesion [OR=3.28, 95%CI (1.41, 7.62), P=0.006], pulsatility index (PI)>3.0 [OR=2.63, 95%CI (1.20, 5.75), P=0.016], quantitative flow ratio (QFR)>0.80 [OR=5.57, 95%CI (2.98, 10.41), P<0.001] and in-hospital complications [OR=4.02, 95%CI (1.59, 10.19), P=0.003] were independent risk factors for the failure of internal mammary artery grafts after CABG. Compared with the prediction model in previous literature [area under receiver operating characteristic curve was 0.632, 95%CI (0.588, 0.688)], the risk prediction model constructed with QFR>0.80, PI>3.0, non-left main lesion and in-hospital complications had a higher predictive ability for early failure of internal mammary artery grafts [area under curve: 0.758, 95%CI (0.707, 0.817); net reclassification index: 0.272, 95%CI (0.180, 0.370); comprehensive discriminative improvement index: 0.109, 95%CI (0.059, 0.158); P<0.05]. The risk score of independent risk factors for internal mammary artery graft failure demonstrated significant MACCE risk stratification efficiency in the 5-year patient follow-up, with the high-risk group showing a significantly higher incidence of MACCE compared to the medium and low-risk groups (P=0.001). Conclusion QFR>0.80, PI>3.0, non-left main lesions, and in-hospital complications are independent risk factors for early failure of internal mammary artery grafts after CABG. The constructed risk prediction model based on this has preliminary capabilities in predicting the risk of internal mammary artery graft failure and MACCE risk stratification, which is beneficial for the postoperative management of CABG patients and improving their mid-long term prognosis.

The anatomical structure of the gingival papilla around the implant is special, and it is difficult to recover after injury. The reduction of its height will have a negative impact on function and esthetics, and it is one of the many problems in implant treatment at present. This paper analyzes the influencing factors of implant gingival papilla height from three aspects: anatomical factors, implant surgical design and implant restorative design, including the classical influencing factors such as the shape of natural teeth, interproximal distance between the implant and the adjacent tooth, soft tissue grafting, and contour of implant restorations, as well as the hot and controversial influencing factors in recent years such as the thickness of soft tissues around the implant, the implant surgical timing, the flap design, and the surgical incision, in order to provide reference for clinicians in the process of implant treatment for gingival papilla preservation and reconstruction.

Evidence-based public health, as the forefront of modern public health practice, has increasingly important in public health field. However, a significant gap remains between the available evidence and its practical application. Effectively disseminating and implementing evidence-based public health practice in real-world settings has become a key challenge in contemporary public health research. In this context, Implementation Science has emerged as a vital discipline. This paper explores the critical role of Implementation Science in public health, reviews the origins and core components of the Consolidated Framework for Implementation Research (CFIR), and analyzes the current application of CFIR in public health through bibliometric methods. Additionally, it discusses specific examples to further elucidate the steps involved in using the CFIR and its application contexts. The findings indicate that since 2015, research on CFIR in public health has progressively increased, showing a continuous upward trend. CFIR applications mainly address context-specific facilitators, health decision-making, barrier and facilitator identification, and community-based participatory evaluation, predominantly employing qualitative and mixed-methods research. This paper not only reviews and analyzes the current use of CFIR in public health but also provides a detailed discussion on its application. The goal is to offer valuable insights for the development of Implementation Science research within China's public health sector.
