ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine (TCM) in clinical practice, but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad, which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix, the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison, use of poison, anti-poison, and detoxification'' were employed to mine the relevant toxicity records, usage and dosage, processing compatibility, and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included, suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity, and the adverse reactions may be related to long-term use, excessive use, and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling, steaming with black beans, and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria, Psoraleae Fructus, and Cistanches Herba. ConclusionReasonable dosage, standard processing, correct compatibility, and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically, the toxicity classification of TCM should be strengthened, and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved, and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols. A systematic search was conducted in Chinese and English databases for clinical practice guideline protocols published during the past ten years. The basic characteristics and reporting of core elements—including registration information, conflict of interest management, evidence grading, development process and timeline planning, as well as dissemination and implementation—were extracted and analyzed. Chi-square tests were performed to explore associations between protocol characteristics and the reporting of core elements. A total of 94 guideline protocols were included, of which 67 were in Chinese(71.28%) and 27 were in English(28.72%). Overall, 82.98% of the guideline protocols were registered, 92.55% reported management of conflicts of interest, 97.87% reported evidence searching, 88.30% reported evidence grading, and 89.36% described dissemination and implementation strategies. However, only 55.32% reported the guideline development process, and merely 23.40% reported timeline planning. Further analysis indicated that the reporting of registration, evidence searching, development process, and timeline planning was associated with year of publication. Differences were observed between domestic and international guidelines in reporting registration, conflict of interest management, development process, time planning, and dissemination and implementation. Guidelines intended for development exhibited higher reporting rates for registration, development process, and dissemination and implementation compared to those planned for updating or adaptation. Although current guideline protocols demonstrate relatively adequate reporting of methodological elements, deficiencies remain in development process and timeline planning. Future efforts should focus on promoting the publication and standardized reporting of guideline protocols, enhancing the international recognition of registration platforms, and strengthening the development process and timeline planning to advance the scientific rigor and transparency of guideline development.

ObjectiveTo investigate the mechanisms by which Mahuang Lianqiao Chixiaodoutang (MLC) improves obesity-type polycystic ovary syndrome (PCOS) through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodsThirty-six female Sprague-Dawley (SD) rats were randomly divided into a blank control group (Con) and an obesity-type PCOS model preparation group. The model was induced by gavage with letrozole (1 mg·kg-1) combined with a high-fat diet (HFD). After model establishment, the obesity-type PCOS model preparation group was further divided into the model group (Mod, normal saline), metformin group (Met, 0.3 g·kg-1), low-dose MLC group (MLC-L, 4.3 g·kg-1), medium-dose MLC group (MLC-M, 8.6 g·kg-1), and high-dose MLC group (MLC-H, 17.2 g·kg-1). Active components of MLC and targets of obesity-type PCOS were screened from databases, a protein-protein interaction (PPI) network was constructed, and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed. The gut microbiota structure was analyzed based on 16S rRNA sequencing and correlated with network pharmacology pathways. Body weight and estrous cycle were dynamically monitored. Ovarian morphology was observed by hematoxylin-eosin (HE) staining. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). Enzyme-linked immunosorbent assay (ELISA) was used to detect levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH), testosterone (T), and estradiol (E2). Western blot was used to detect the protein expression levels of phosphorylated PI3K/PI3K (p-PI3K/PI3K), phosphorylated Akt/Akt (p-Akt/Akt), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax). ResultsNetwork pharmacology screening identified 124 active components of MLC and 408 overlapping targets between the herbal formula and the disease. Core targets such as Akt1 and Bcl-2 were revealed. As indicated by 16S rRNA sequencing, the abundances of Lachnospiraceae, Lachnoclostridium, and Dorea were increased in the MLC groups (P<0.05), while the abundance of Veillonella was decreased (P<0.05). KEGG correlation analysis integrating network pharmacology and gut microbiota data showed significant enrichment of the PI3K/Akt signaling pathway. Animal experiments showed that, compared with the Mod group, body weight decreased to normal levels in the Met, MLC-M, and MLC-H groups. The estrous cycle became regular. The number of corpora lutea increased and cystic follicles decreased. Serum levels of T, FSH, and LH/FSH were reduced (P<0.05, P<0.01), while the E2 level was increased (P<0.01). Ovarian cell apoptosis was reduced (P<0.01), and the protein expression levels of p-PI3K/PI3K, p-Akt/Akt, and Bcl-2 in ovarian tissue were significantly increased, whereas Bax protein expression was significantly decreased (P<0.05, P<0.01). ConclusionMLC can regulate gut microbiota structure, effectively improve ovarian pathology in rats with obesity-type PCOS, and inhibit ovarian granulosa cell apoptosis. The mechanism may be associated with upregulation of the PI3K/Akt signaling pathway.

Liver failure (LF) is a severe clinical syndrome characterized by severe impairment or decompensation of liver function. At present, the key role of immune molecules in the pathogenesis of LF has been well established. These molecules not only directly participate in the pathological process of LF, but also influence the course of LF by modulating the behavior of immune cells. In addition, immune molecules can be used as potential biomarkers for evaluating the prognosis of LF. This article summarizes the role of immune molecules in LF and explores the therapeutic strategies based on these immune molecules, in order to provide new directions for the diagnosis and treatment of LF.

The chemical composition of Paeoniae Radix Alba(PRA) is complex, with primary secondary metabolites including monoterpenoids, tannins, triterpenoids, and flavonoids. In previous studies on the material basis of PRA, it was found that, in addition to the widely studied characteristic monoterpene glycosides, tannic acid components also play an important role in the efficacy of PRA. However, their pharmacological effects have not been thoroughly investigated. This paper reviews the tannic acid components in PRA, including pentagaloyl glucose(PGG), tetragaloyl glucose(TGG), trigaloyl glucose(TriGG), and gallic acid, along with their structures, properties, and characteristics to provide a detailed discussion of their pharmacological activities and related mechanisms, aiming to offer a theoretical basis for the material basis research and clinical application of PRA.

This study explores the basic characteristics and potential functions of the terpene synthase(TPS) gene family members in Lonicera japonica. The L. japonica TPS(LjTPS) gene family was identified and functionally analyzed using bioinformatics methods. The results showed that a total of 70 members of the LjTPS gene family were identified in L. japonica, with protein lengths ranging from 130 to 1 437 amino acids. Most of these proteins were hydrophilic, and they were unevenly distributed across nine chromosomes. Phylogenetic analysis showed that the LjTPS gene family members were divided into six subfamilies, mainly consisting of members from the TPS-a, TPS-b, and TPS-e subfamilies. Promoter cis-acting element analysis showed that LjTPS members contained a large number of stress-responsive cis-acting elements. Aphid inoculation experiments showed that key enzyme genes in the MVA pathway for terpenoid backbone synthesis in L. japonica, such as HMGS, HMGR, MK, MPD, and the key enzyme gene in the DXP pathway, DXS, exhibited an initial increase followed by a decrease under aphid stress. The qRT-PCR analysis showed that the expression levels of the α-farnesene synthase genes LjTPS34 and LjTPS39 were down-regulated, while the expression levels of(E)-β-caryophyllene synthase genes LjTPS15 and LjTPS17 were up-regulated 12 h before aphid feeding, then began to decline. Farnesyl pyrophosphate synthase(FPS), which interacted with these genes, also displayed a pattern of increasing followed by decreasing expression. The expression of linalool synthase genes LjTPS12 and LjTPS33 was significantly up-regulated after 72 h of aphid feeding(P<0.000 1), reaching 24.39 and 22.64 times the initial expression, respectively. This pattern was in close alignment with the trend of linalool content in L. japonica. This study provides a theoretical foundation for future research on the interaction between L. japonica and pests, as well as on the functional roles of the LjTPS gene family.

Through evidence mapping, this paper systematically summarized the research evidence on the use of traditional Chinese medicine(TCM) in treating renal anemia, displaying the distribution of evidence in this field. A systematic search was conducted across databases, including CNKI, Wanfang, VIP, SinoMed, Springner, PubMed, Engineering Village, and Web of Science, targeting studies published up to June 30, 2024. The research evidence was summarized and displayed through a combination of graphs, tables, and text. A total of 264 interventional studies, 37 observational studies, and 7 systematic reviews were included. The annual publication volumes related to TCM treatment in renal anemia showed an overall upward trend, with most studies involving sample sizes between 60 and 120 participants(224 articles, 74.42%). Intervention measures were categorized into 21 types, with oral TCM decoctions being the most common medicine(171 times, 56.81%). The use of self-made prescriptions was the most common TCM intervention method. The intervention duration was mainly between 8 weeks and 3 months(239 articles, 79.40%). The most frequently reported TCM syndrome was spleen and kidney Qi deficiency. The top 2 outcome indicators were the anemia indicators and renal injury/renal function markers. However, several issues were identified in these studies, such as insufficient attention to the sources, social/geographical information, and temporal continuity of research subjects in observational research. Randomized controlled trials mostly had a high risk of bias, mainly due to issues such as randomization bias, blinding bias, and failure to register research protocols. The methodology quality of systematic reviews was generally low, mainly due to inadequate inclusion of literature, failure to specify funding sources, and lack of pre-registrations. While the report quality of systematic review was acceptable, there were significant gaps in the reporting of protocols, registration, and funds. The results show that these issues affect the quality of research and the reliability of findings on TCM in treating renal anemia, underscoring the need to address them to conduct higher-quality research and provide more reliable medical evidence for TCM in treating renal anemia.

Qing court records show that Arecae Semen was extensively applied. The royal medical records of the Qing Dynasty document nine types of Arecae Semen, with the Palace Museum preserving seven kinds, totaling twelve cultural relics. Historical documents and physical artifacts corroborate each other, providing evidence for the study of the supply channels and court processing of Arecae Semen in the Qing court. According to relevant Qing court archival records, the sources of Arecae Semen used in the imperial court were diverse, including tributes from foreign countries such as Vietnam and Gurkha, annual tributes from local governments in Guangdong, gifts from close aides, and commodities purchased by the Imperial Household Department from civilian shops. The imperial physicians of the Qing court placed great emphasis on the specifications of Arecae Semen slices and were extremely meticulous about their processing. The variety of Arecae Semen slices used in the Qing palace exceeded those recorded in the botanical texts of the era. Compared with the commonly used processing methods for Arecae Semen in the Qing Dynasty, the imperial physicians adjusted the properties and efficacy of the herbs through different processing techniques, based on the patient's condition, constitution, and other factors, in order to meet the clinical treatment needs of the court. The slicing of Arecae Semen in the Qing court required strict control of thickness, with an average thickness of 0.44 mm, which is significantly thinner than the Arecae Semen slices found in today's markets. The texture was softer, making them easier to chew and absorb. Both the Qing court Arecae Semen slices and the Muxiang Binglang Pills focused on the use of authentic medicinal materials, ensuring the quality of the medicine and enhancing the efficacy of Arecae Semen through meticulous selection and preparation.
