In order to investigate the chemical constituents of glycosides in Aconitum tanguticum (Maxim.) Stapf, column chromatographic techniques such as silica gel, ODS, Sephadex LH-20, and semi-preparative high performance liquid chromatography were used to afford eight glycosides from the n-butanol fraction of the 85% ethanol extract of Aconitum tanguticum. Based on the physicochemical properties and spectral data, these compounds were identified as N-4-O-(β-D-glucopyranosyl)-phenethylbenzamide (1), N-(2'-β-D-glucopyranosyl-5'-methoxysalicyl)-4-hydroxy-3-methoxyanthranilic acid methyl ester (2), N-(2'-β-D-glucopyranosyl-5'-hydroxysalicyl)-4-hydroxy-3-methoxyanthranilic acid methyl ester (3), salidroside (4), benzyl primeveroside (5), phenethanol-β-D-xylose-(1''→6')-β-D-glucopyranoside (6), 4-dihydroxyphenethoxy-8-O-β-D-[6-O-(4-O-β-D-glucopyranosyl)-feruloyl]-glucopyranoside (7), phenethanol-α-L-arabinopyranosyl-(1''→6')-β-D-glucopyranoside (8). Among them, compounds 1 and 2 were new compounds, and compounds 5,6,8 were isolated from Aconitum tanguticum for the first time.

Informed consent constitutes a fundamental ethical principle in medical practice. With the in-depth integration of generative artificial intelligence (AI) represented by Chat Generative Pre-trained Transformer (ChatGPT) with medicine, it has brought revolutionary development to traditional informed consent while also introducing new ethical challenges. ChatGPT offers features such as improving the readability of informed consent content, enhancing its comprehensiveness and accuracy, and increasing the convenience of obtaining informed consent. However, as the application of ChatGPT in informed consent is still in the exploratory stage, it is imperative to proactively and fully consider the accompanying ethical issues, such as information security, liability determination, transparency, and fairness. This paper conducted an ethical analysis on the challenges faced by generative AI, represented by ChatGPT, in the application of informed consent and proposed countermeasures, such as upholding free and fully informed consent, strengthening the balance of rights and obligations in informed consent, and establishing a transparent and fair supervision mechanism. The aim was to promote the ethically compliant, orderly, and controllable development of generative AI in the field of medical informed consent.

ObjectiveTo investigate the effect of Danggui Shaoyaosan on the expression of Toll-like receptor 4/nuclear factor-kappa B p65/NOD-like receptor protein 3 (TLR4/NF-κB p65/NLRP3) signaling pathway in the renal tissues of db/db mice with spontaneous diabetes, and to explore the potential mechanism by which Danggui Shaoyaosan alleviates inflammation in diabetic kidney disease (DKD). MethodsThirty db/db mice were divided into five groups: A model group, Danggui Shaoyaosan low- (16.77 g·kg-1·d-1), medium- (33.54 g·kg-1·d-1), and high-dose (67.08 g·kg-1·d-1) intervention groups, as well as an irbesartan group (0.025 g·kg-1·d-1) by the random number table method, with 6 mice in each group. Additionally, 6 db/m mice were assigned to the normal group. After 8 weeks of intervention, the following parameters were determined by corresponding methods: body weight, fasting blood glucose (FBG), 24-hour urinary protein (24 h-UTP), and serum creatinine (SCr) levels, renal histopathological analysis by hematoxylin-eosin (HE) staining, Masson staining, and periodic acid-Schiff (PAS) staining, the protein and mRNA expression levels of TLR4, NF-κB p65, NLRP3, tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-18 (IL-18) by Western blot and Real-time quantitative polymerase chain reaction (Real-time PCR), as well as TLR4, NF-κB p65, and NLRP3 protein expression in renal tissues by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group exhibited increased body weight, FBG, 24 h-UTP, and SCr levels (P<0.05); disordered renal structure, thickened basement membrane, and interstitial inflammatory cell infiltration, elevated TLR4, NF-κB p65, NLRP3, TNF-α, IL-1β, IL-6, and IL-18 expression; as well as decreased IL-10 expression (P<0.05). Compared with the model group, these pathological changes and biochemical abnormalities were reversed in the medicine intervention groups to varying degrees (P<0.05). ConclusionDanggui Shaoyaosan may delay DKD progression by alleviating renal inflammatory response and reducing urinary protein excretion via modulating the TLR4/NF-κB p65/NLRP3 signaling pathway.

OBJECTIVE To explore the influencing factors of Shenfukang capsule in the treatment of chronic kidney disease (CKD) and construct a nomogram prediction model for evaluating its therapeutic efficacy. METHODS CKD patients who were hospitalized from July 2019 to August 2022 in the First Affiliated Hospital of Guangxi Medical University and treated with Shenfukang capsule were selected as study subjects. Clinical data of the patients were collected from the hospital’s electronic medical record system, and they were divided into an effective group and an ineffective group based on treatment outcomes. Lasso-Logistic multivariate regression analysis was used to screen the influencing factors of the efficacy of Shenfukang capsule. Using the effectiveness of Shenfukang capsule treatment as the prediction outcome and the screened influencing factors as predictor variables, a nomogram prediction model was constructed using R software. All patients were randomly divided into a training cohort and a validation cohort. The discriminative ability, calibration, and clinical net benefit of the model were evaluated using the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis, respectively. RESULTS Lasso-Logistic regression analysis revealed that concurrent diabetes mellitus, decreased levels of blood urea nitrogen, triglycerides, and serum phosphorus, as well as prolonged prothrombin time and elevated apolipoprotein AⅠ levels, were influencing factors for reduced efficacy of Shenfukang capsule in CKD treatment. The evaluation results of the nomogram prediction model showed that the area under curve values were 0.745 and 0.797 in the training and validation cohorts, respectively, which were close and both exceeded 0.70, indicating stable predictive performance. The calibration curves demonstrated good agreement in both datasets, suggesting satisfactory calibration performance. The clinical decision curves were positioned above the two extreme reference lines, indicating high clinical benefit of the model. CONCLUSIONS Diabetes mellitus, blood urea nitrogen, triglycerides, apolipoprotein AⅠ, serum phosphorus, and prothrombin time were factors associated with the efficacy of Shenfukang capsule in CKD patients. The nomogram prediction model established in this study may provide a basis for rational clinical application of Shenfukang capsule and for improving its therapeutic efficacy in CKD.

Objective: This study employed next-generation sequencing (NGS) for large-scale genotyping of 42 blood group systems in blood donors to evaluate its applicability in multi-system blood group identification and rare blood type repository construction, while exploring the complementary value of third-generation sequencing (TGS) in haplotype phasing and variant capture in regions with insufficient sequencing depth for ABO ambiguous samples. Methods: A total of 562 regular blood donors (median donation frequency 11 times) from a blood center were enrolled. NGS was used for genotyping of 42 blood group systems, with a focused analysis on 12 systems essential for rare blood type repository construction: MNS, Lutheran, Kell, Duffy, Kidd, Diego, Yt, Colton, Gerbich, Ok, H, and I. TGS was employed to resolve haplotype phasing (i. e., determining whether different mutation sites are located on the same chromosome) in 12 ABO samples with discrepancies between forward and reverse typing. Serological and genotyping results were compared for MNS, Duffy, Kidd, Lewis, and ABO systems. Results: NGS-based genotyping revealed that Fy (a-b+) in the Duffy system accounted for 0.87% (4/458), and Di (a+b+) in the Diego system accounted for 10.62% (31/292). The Lutheran, Kell, Yt, Colton, H, Ok, I, and Gerbich systems exhibited near-uniform phenotype distributions. Among the 12 ABO ambiguous samples, NGS yielded multiple possible genotype combinations in 5 cases due to inability to phase alleles, whereas TGS uniquely resolved the genotypes through long-read sequencing. In one case, NGS detected only 2 mutation sites due to insufficient sequencing depth, while TGS identified all 11 sites and assigned the A1 phenotype. Concordance rates between serology and genotyping were: Duffy 96.55% (140/145), ABO 96.43% (513/532), Kidd 94.17% (97/103), MNS 85.07% (57/67), and Lewis 68.18% (75/110). In the MNS system, 7 of 8 samples serologically typed as M+N+ but genotyped as M-N+ carried GYPB variants. Lewis discrepancies predominantly featured genotype Le (a-b+) with serological phenotypes of Le (a+b-), Le (a+b+), or Le (a-b-). The NGS platform completed sequencing of 192 samples within 2 weeks. Conclusion: The tiered genotyping strategy combining NGS, TGS, and serology enables multi-system blood group identification in large-scale blood donor populations. TGS provides complementary value in phasing ambiguous ABO samples and detecting variants in regions with insufficient sequencing depth. This study provides a technical framework and baseline frequency data for the expansion of a local rare blood type repository. However, standardization and cost-effectiveness of this strategy require further validation with expanded sample sizes, and serological confirmation should be retained for secretion status-related systems such as Lewis.

ObjectiveTo evaluate the clinical efficacy and safety of Wenshen Yangxue decoction combined with endometrial microstimulation in the treatment of infertile patients with polycystic ovary syndrome (PCOS, syndrome of kidney-Yang deficiency and blood stasis). MethodsA randomized, positive-drug parallel-controlled, open-label clinical study was conducted. A total of 240 infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis who met the inclusion and exclusion criteria were randomly assigned into 4 groups, with 60 patients in each group. The control group was treated with clomiphene citrate (50-100 mg·d-¹, orally for 5-10 consecutive days) for ovulation induction. On the basis of the therapy in the control group, the Wenshen group was additionally treated with Wenshen Yangxue decoction (250 mL, warm oral administration, twice daily, in the morning and evening), and the stimulation group received endometrial microstimulation during the early follicular phase. The combined group was treated with clomiphene citrate plus Wenshen Yangxue decoction (at the same dosages as aforementioned) and endometrial microstimulation. The course of treatment for all the groups was 3 menstrual cycles. The pregnancy rate, ovulation status, sex hormone levels, glucose metabolism indicators, coagulation function, endometrial thickness, traditional Chinese medicine (TCM) symptom scores, and adverse reactions were observed in each group. ResultsA total of 239 patients were included in the final analysis, with 59 patients in the Wenshen group and 60 patients in each of the other three groups. The pregnancy rates were 43.3%(26/60) in the combined group and 32.2%(19/60) in the Wenshen group, both significantly higher than that (10%) in the control group (χ2=17.56,P<0.01). Compared with the control group, the combined and Wenshen groups had increased mature follicle rates (P<0.01), while the Wenshen group showed a decreased luteinization rate (P<0.05). All the groups exhibited significant reductions in TCM symptom scores after treatment, and the Wenshen and combined groups had lower scores than the control group (P<0.01). No statistically significant difference was found in the incidence of adverse events among the four groups, and all the adverse events were mild. ConclusionWenshen Yangxue decoction combined with endometrial microstimulation can alleviate the TCM symptoms of infertile PCOS patients with the syndrome of kidney-Yang deficiency and blood stasis, promote follicular maturation and ovulation, increase the cumulative pregnancy rate, and has good safety. It can provide new clinical evidence for the integrated traditional Chinese and Western medicine treatment of PCOS infertility.

Macrophages are innate immune cells connected with the development of inflammation. Retinoic acid has previously been proved to have anti-inflammatory and anti-arthritic properties. However, the exact mechanism through which retinoic acid modulates arthritis remains unclear. This study aimed to investigate whether retinoic acid ameliorates rheumatoid arthritis by modulating macrophage polarization. This study used retinoic acid to treat mice with adjuvant arthritis and evaluated anti-inflammatory effects by arthritis score, thermal nociceptive sensitization test, histopathologic examination and immunofluorescence assays. In addition, its specific anti-arthritic mechanism was investigated by flow cytometry, cell transfection and inflammatory signaling pathway assays in RAW264.7 macrophages in vitro. Retinoic acid significantly relieved joint pain and attenuated inflammatory cell infiltration in mice. Furthermore, this treatment modulated peritoneal macrophage polarization, increased levels of arginase 1, as well as decreased inducible nitric oxide synthase expression. In vitro, we verified that retinoic acid promotes macrophage transition from the M1 to M2 type by upregulating mitogen-activated protein kinase (MAPK) phosphatase 1 (MKP-1) expression and inhibiting P38, JNK and ERK phosphorylation in lipopolysaccharide-stimulated RAW264.7 cells. Notably, the therapeutic effects of retinoic acid were inhibited by MKP-1 knockdown. Retinoic acid exerts a significant therapeutic effect on adjuvant arthritis in mice by regulating macrophage polarization through the MKP-1/MAPK pathway, and play an important role in the treatment of rheumatic diseases.

Peri-implant diseases are characterized by the resorption of hard tissue and the inflammation of soft tissue. Epigenetics refers to alterations in the expression of genes that are not encoded in the DNA sequence, influencing diverse physiological activities, including immune response, inflammation, and bone metabolism. Epigenetic modifications can lead to tissue-specific gene expression variations among individuals and may initiate or exacerbate inflammation and disease predisposition. However, the impact of these factors on peri-implantitis remains inconclusive. To address this gap, we conducted a comprehensive review to investigate the associations between epigenetic mechanisms and peri-implantitis, specifically focusing on DNA methylation and microRNAs (miRNAs or miRs). We searched for relevant literature on PubMed, Web of Science, Scopus, and Google Scholar with keywords including "epigenetics," "peri-implantitis," "DNA methylation," and "microRNA." DNA methylation and miRNAs present a dynamic epigenetic mechanism operating around implants. Epigenetic modifications of genes related to inflammation and osteogenesis provide a new perspective for understanding how local and environmental factors influence the pathogenesis of peri-implantitis. In addition, we assessed the potential application of DNA methylation and miRNAs in the prevention, diagnosis, and treatment of peri-implantitis, aiming to provide a foundation for future studies to explore potential therapeutic targets and develop more effective management strategies for this condition. These findings also have broader implications for understanding the pathogenesis of other inflammation-related oral diseases like periodontitis.
