ObjectiveAngelicae Sinensis Radix, a commonly used medicinal herb with both medicinal and edible properties, is frequently adulterated in the market, severely affecting the clinical efficacy of preparations. While qualitative identification techniques for adulterants and counterfeits are now relatively mature, quantitative detection methods for adulterated processed products remain unexplored. Quantitative detection research of Angelicae Sinensis Radix and its primary closely related adulterant, "Tu Danggui" (Angelica gigas), was conducted to establish a herbal quantitative molecular detection (Herb-Q) method for Angelicae Sinensis Radix and its processed products, providing a model for the establishment of quantitative detection technologies for Angelicae Sinensis Radix and related health products. MethodsThe specific single-nucleotide polymorphism (SNP) loci of Angelicae Sinensis Radix and Angelica gigas Nakai were screened based on the complete chloroplast genome sequence. The specific SNP loci of Angelicae Sinensis Radix were selected for quantitative methodological investigations (linearity, limit of quantification, limit of detection, and reproducibility) by mixing the powder of the herbs with different adulteration ratios. Huoxue Zhitong powder with three distinct adulteration ratios (15%, 25%, and 35%) was utilized to ascertain the precision of the Herb-Q method for the quantitative detection of Chinese patent medicines containing Angelicae Sinensis Radix. ResultsBy comparing the 123 chloroplast genome sequences of Angelicae Sinensis Radix, based on the principles of intraspecies conservation, interspecies specificity, and meeting the requirements of pyrophosphate high-throughput sequencing, it was determined that 9 674th locus (A/G) in the chloroplast genome sequence NC_042826.1 and 38 592nd locus (T/C) in the chloroplast genome sequence NC_029393.1 could be the exclusive molecular identification loci of Angelicae Sinensis Radix and Angelica gigas Nakai, respectively. The linear relationship R2 of the Herb-Q method established by selecting the specific 9 674th locus (A/G) of Angelicae Sinensis Radix was 0.997 4 (R2>0.99), indicating an excellent linear relationship. The limits of quantification and detection were established at 2.0%, exhibiting excellent reproducibility [relative standard deviation(RSD)<2.0%]. The established quantitative system based on the Herb-Q method detected the adulteration amount of counterfeit A. gigas in the Huoxue Zhitong powder, with an average deviation of 1.3% for three molecular quantitative replicates. ConclusionThis research demonstrates that the Herb-Q quantitative detection method established based on the 9 674th locus (A/G) in the chloroplast genome sequence NC_042826.1 of Angelicae Sinensis Radix has good applicability, objectivity, and accuracy for Angelicae Sinensis Radix and A. gigas, and its processed products. This method has the capacity to provide technical support for the quantitative detection of commercially available Angelicae Sinensis Radix derivatives, including traditional Chinese medicinal preparations, dietary supplements, and nutraceuticals.

ObjectiveTo explore the latent profiles of sleep patterns and their association with gastrointestinal heat accumulation syndrome in preschool children in Beijing. MethodsA cross-sectional study design was adopted, and preschool children were recruited from 57 kindergartens in Beijing using convenience sampling. Sleep characteristics and gastrointestinal heat accumulation syndrome was assessed using the Chinese version of the Sleep Disturbance Scale for Children (SDSC) and Self-rating Diagnostic Scale for Gastrointestinal Heat Retention Syndrome in children (GHRS). Latent profile analysis (LPA) was applied to identify distinct sleep-related subgroups, and multivariate logistic regression was used to analyze the association between different sleep profiles and gastrointestinal heat accumulation syndrome. ResultsA total of 6878 preschool children were included in the study. Among them, 3.46% of the children (238/6878) had sleep disorders, while 54.42% (3743/6878) had gastrointestinal heat accumulation. Compared to children without gastrointestinal heat accumulation syndrome, those with this syndrome exhibited a higher prevalence of sleep disorders, higher SDSC scores, higher T-transformed total scores, and higher scores across all dimensions, including disorders of initiating sleep, disorders of maintaining sleep, sleep hyperhidrosis, sleep breathing disorders, parasomnias, nonrestorative sleep and excessive somnolence (P<0.01). Latent profile analysis identified four distinct sleep characteristic profiles, which were the mixed high-symptom group (32.39%, 2228/6878), sleep initiation and maintenance difficulty symptom group (49.07%, 3375/6878), low-symptom group (14.19%, 976/6878), and the group with no significant symptoms (4.35%, 299/6878). Multivariate logistic regression analysis demonstrated that the mixed high-symptom group, sleep initiation and maintenance difficulty symptom group, and low-symptom group were significantly associated with gastrointestinal heat accumulation syndrome. Among them, the mixed high-symptom group had the most significant association with gastrointestinal heat accumulation (OR=12.657, P<0.001), followed by the sleep initiation and maintenance difficulty symptom group (OR=4.964, P<0.001). ConclusionSleep characteristics in preschool children mainly present as composite patterns with different symptom combinations. Moreover, the sleep latent profiles of the mixed high-symptom group, the sleep initiation and maintenance difficulty symptom group, and the low-symptom group were significantly associated with gastrointestinal heat accumulation syndrome.

ObjectiveTo establish the mouse models of psoriasis-like lesions induced by continuous cold exposure or intermittent cold exposure combined with imiquimod (IMQ), and to evaluate the interventional effects of Kaixuan Jiedu core prescription (KXJD) on the two models. MethodsMale C57BL/6J mice were selected and classified into two experimental batches. The first batch of 36 mice was randomized into a room temperature group, a continuous cold exposure (10 ℃/24 h) group, and an intermittent cold exposure (10 ℃/6 h) group. Each group was further divided into a normal subgroup and a model subgroup (topical application of IMQ to induce skin lesions), with 6 mice in each subgroup, for modeling and evaluation. The second batch of 54 mice, with 6 in each group, were subjected to the same temperature grouping with an additional KXJD (30.42 g·kg-1, continuous gavage for 5 days) group. Comprehensive evaluation of model characteristics and KXJD efficacy was conducted through Psoriasis Area and Severity Index (PASI) scoring, skin temperature measurement by infrared thermography, histopathological observation by hematoxylin-eosin (HE) staining, detection of vascular endothelial growth factor (VEGF) and platelet endothelial cell adhesion molecule 1 (CD31) by immunohistochemistry, detection of Claudin-1 and Occludin by immunofluorescence assay, determination of serum levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-10 by enzyme-linked immunosorbent assay (ELISA), and quantification of mRNA levels of IL-17A, IL-23, IL-6, and chemokine ligand 20 (CCL20) in skin lesions by quantitative Real-time polymerase chain reaction (Real-time PCR). ResultsModel mice in all temperature groups exhibited typical psoriasis-like skin lesions. Compared with the normal groups, the model groups showed increased PASI scores, decreased skin temperatures (P<0.05), obvious epidermal thickening, parakeratosis, and dermal inflammatory cell infiltration, as well as elevated mRNA levels of IL-17A, IL-23, IL-6, and CCL20 (P<0.05). Cold exposure further aggravated psoriasis. The total PASI score of the intermittent cold exposure model group was higher than that of the room temperature model group (P<0.05). The serum IL-10 did not show a compensatory elevation, and the blood vessels presented a characteristic of elevated CD31 expression (P<0.05) without a synchronous increase in VEGF. The continuous cold exposure model group exhibited more significant dermal capillary tortuosity and dilation, with the highest mRNA levels of IL-17A, IL-23, IL-6, and CCL20 among all groups. Compared with the respective model groups, KXJD intervention alleviated skin lesions, reduced epidermal thickness and inflammatory cell infiltration, and increased skin temperature, with the temperature increase being particularly significant in the intermittent cold exposure+KXJD group (P<0.05). Furthermore, KXJD down-regulated the expression of VEGF and CD31, restored the expression of Claudin-1 and Occludin, decreased the mRNA levels of IL-17A and IL-23 (P<0.05), and reduced the serum TNF-α level. ConclusionThis study successfully established compound psoriasis-like mouse models induced by cold exposure combined with IMQ. It confirms that cold aggravates the severity of psoriasis by exacerbating the closure of Xuanfu (sweat pores), microcirculation disorders, and immune imbalance. Moreover, different cold exposure patterns have distinct mechanism differences. Continuous cold exposure focuses on enhancing the inflammatory response via the IL-23/IL-17 axis and angiogenesis, simulating chronic aggravation under a long-term cold environment. Intermittent cold exposure tends to impair immune regulation and induce microvascular endothelial stress, corresponding to acute exacerbations caused by sudden temperature drops. KXJD can effectively alleviate psoriasis-like skin lesions under cold conditions by unblocking Xuanfu, regulating vasomotor function, and correcting abnormal immune-inflammatory responses.

ObjectiveTo investigate the ameliorative effects of Kaixuan Jiedu core prescription (KXJD) on skin lesions in psoriasis-like mouse models under cold environment exposure, and to analyze its influences on transient receptor potential (TRP) channels and related neuroimmune regulatory factors. MethodsThirty-six C57BL/6J mice were randomized into 6 groups, with 6 mice in each group. Two feeding conditions were set: Normal temperature and cold [simulating a cold environment at (10±0.5) ℃, for 6 h daily]. Mice were induced to develop psoriasis-like lesions by applying imiquimod externally. The model mice were allocated into model groups and KXJD (30.42 g·kg-1, continuous gavage for 5 days) groups. Normal mice were used as the control group. Specifically, mice were allocated into normal temperature, normal temperature model, normal temperature+KXJD, cold exposure control, cold exposure model, and cold exposure+KXJD groups. The pathological changes in skin lesions were observed by hematoxylin-eosin (HE) staining. The expression of cluster of differentiation (CD) 3+ T lymphocytes, CD11c+ dendritic cells (DCs), phosphorylated extracellular signal-regulated kinase (p-ERK), and substance P (SP) were detected by immunofluorescence assay. The protein level of transient receptor potential cation channel subfamily M member 8 (TRPM8) in the skin tissue was determined by Western blot. The expression of TRPM8, transient receptor potential cation channel subfamily V member 1 (TRPV1), transient receptor potential cation channel subfamily A member 1 (TRPA1), and transient receptor potential cation channel subfamily V member 2 (TRPV2) at the protein and mRNA levels was determined by immunohistochemistry and Real-time PCR, respectively. The levels of calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY) in the serum were analyzed by enzyme-linked immunosorbent assay (ELISA). The enrichment analysis of differentially expressed genes (DEGs) and TRP pathway network construction were conducted based on the GEO database. The co-expression of TRPM8 and CGRP in the skin lesions was verified by immunofluorescence double labeling. ResultsBoth the normal temperature and cold exposure model groups showed typical psoriasis-like skin lesions. Compared with the normal temperature and cold exposure control groups, the model groups had excessive epidermal keratinization, thickened spinous layer, and inflammatory infiltration in the dermis, with increased pathological scores (P<0.05), increased infiltration of CD3+ and CD11c+ cells and expression of p-ERK and SP, upregulated mRNA levels of TRPM8, TRPA1, and TRPV2, downregulated mRNA level of TRPV1 (P<0.05), and reduced content of CGRP and increased content of NPY in the serum. Compared with the normal temperature and cold exposure model groups, KXJD reduced the pathological manifestations and pathological scores of psoriasis-like skin lesions (P<0.05), and inhibited the infiltration of CD3+ and CD11c+ cells and the expression of p-ERK and SP. Gene enrichment analysis suggested that the DEGs of psoriasis were significantly enriched in the interleukin (IL)-17 signaling pathway and TRP channel inflammatory regulation. Compared with the normal temperature and cold exposure model groups, KXJD reversed the abnormal mRNA levels of genes related to the TRP channel subfamilies (P<0.05), increased the CGRP level, and decreased the NPY level. Immunofluorescence double labeling further confirmed that compared with the model groups, KXJD down-regulated the co-expression of TRPM8 and CGRP in the skin lesions. ConclusionKXJD may ameliorate psoriasis-like skin lesions by downregulating the overexpressed cold-sensitive receptor TRPM8 in skin lesions and correcting the disorder of neuropeptide (such as SP and CGRP) release mediated by it, thereby inhibiting the IL-23/helper T cell 17 (Th17) core inflammatory pathway, suppressing the infiltration of inflammatory cells and the activation of the ERK signaling pathway, and regulating the Xuanfu (sweat pore)-TRPM8-neuroimmune response axis.

ObjectiveTo investigate the ameliorative effects and mechanisms of Kaixuan Jiedu core prescription (KXJD) on neuroimmunological inflammation in imiquimod (IMQ)-induced psoriasis-like mice. MethodsA total of 24 C57BL/6J mice were randomly divided into four groups (n=6): Normal, model, KXJD, and tropomyosin receptor kinase A (TrkA) inhibitor GW441756 groups. The mice in the model, KXJD, and GW441756 groups were topically treated with 5% IMQ cream (62.5 mg·d-1) on the back to induce psoriasis-like inflammation. The KXJD group received KXJD by gavage (30.42 g·kg-1), the GW441756 group received intraperitoneal injection of GW441756 (10 mg·kg-1), and the normal and model groups received an equal volume of normal saline by gavage, with continuous intervention for 5 days. The severity of skin lesions was evaluated using the psoriasis area and severity index (PASI). Hematoxylin-eosin (HE) staining was used to measure epidermal thickness and observe pathological changes in the lesioned skin. Immunohistochemistry was employed to detect the expression of proliferating cell nuclear antigen (Ki67) and interleukin-17A (IL-17A) in the lesioned skin. Enzyme-linked immunosorbent assay (ELISA) was used to quantify the levels of interleukin-23 (IL-23) and calcitonin gene-related peptide (CGRP) in the lesioned tissues. Western blot was used to detect the expression of TrkA and phosphorylated TrkA (p-TrkA). Immunofluorescence assay was performed to detect the expression of TrkA receptor, protein gene product 9.5 (PGP9.5), cluster of differentiation 11c (CD11c), and CGRP in the lesions. Flow cytometry was used to detect the activation of splenic dendritic cells (DCs). ResultsCompared with the normal group, the model group exhibited typical psoriasis-like inflammation, characterized by erythema, infiltration and scaling, with histopathological findings of epidermal hyperkeratosis and acanthosis. The model group showed significantly increased expression of Ki67, IL-17A, IL-23 and p-TrkA (P<0.05, P<0.01), increased fluorescence intensity of CD11c, and significantly decreased CGRP expression (P<0.05). The splenic DC activation was significantly enhanced, as indicated by the increased mean fluorescence intensity (MFI) of CD86 (P<0.05). Compared with the model group, both the KXJD and GW441756 groups showed amelioration of the psoriasis-like skin inflammation, with significantly down-regulated expression of IL-17A, IL-23 and p-TrkA (P<0.05, P<0.01), significantly up-regulated expression of CGRP (P<0.01), reduced CD11c+ DC infiltration, and restored splenic DC activation balance (down-regulated CD86 MFI and up-regulated CD80 and CD40 MFI). Furthermore, the inhibitory effect of KXJD on Ki67 was significantly superior to that of the GW441756 group (P<0.01). ConclusionKXJD may alleviate IMQ-induced psoriasis-like inflammation in mice by targeting and inhibiting TrkA receptor phosphorylation, regulating CGRP expression in the lesions, and ameliorating aberrant activation of dendritic cells, while also significantly inhibiting keratinocyte proliferation.

ObjectiveTo investigate the effects and molecular mechanisms of Kaixuan Jiedu core prescription (KXJD) on neuroinflammation and immuno-inflammation in the mouse model of imiquimod (IMQ)-induced psoriasis-like skin lesions by regulating the nerve growth factor (NGF)-tropomyosin receptor kinase A (TrkA)/transient receptor potential vanilloid 1 (TRPV1)-protease-activated receptor-2 (PAR-2) signaling pathway. MethodsA psoriasis-like skin lesion model was established in male C57BL/6J mice with IMQ. A total of 24 mice were randomized into four groups (n=6 per group): Blank control, model, methotrexate (MTX, 1 mg·kg-1), and KXJD (30.42 g·kg-1). Immunohistochemistry was employed to detect the expression of cluster of differentiation 3 (CD3), EGF-like module-containing mucin-like hormone receptor-like 1 (F4/80), lymphocyte antigen 6 complex locus G (Ly-6G), substance P (SP), calcitonin gene-related peptide (CGRP), NGF, phosphorylated TrkA (p-TrkA), phosphorylated TRPV1 (p-TRPV1), and PAR-2 in skin lesions. Serum levels of interleukin-17A (IL-17A) and interleukin-23 (IL-23) were measured by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence assay and Western blot were employed to determine the expression of phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK) and phosphorylated nuclear factor-κB p65 (p-NF-κB p65). Reverse transcription quantitative polymerase chain reaction (Real-time PCR) was used to measure the mRNA levels of interleukin-1β (IL-1β), tumor necrosis factor (TNF), interleukin-6 (IL-6), and C-X-C motif chemokine ligand 1 (CXCL1) in skin lesions. Correlation analysis was performed. ResultsCompared with the blank control group, the model group showed increased positive areas of CD3+, F4/80+, and Ly-6G+ in skin lesions (P<0.05), elevated serum levels of IL-17A and IL-23 (P<0.05), increased positive areas of SP and CGRP in skin lesions (P<0.05), increased positive areas of NGF, p-TrkA, p-TRPV1, and PAR-2 (P<0.05), elevated ratios of p-p38 MAPK/p38 MAPK and p-NF-κB p65/NF-κB p65 (P<0.05), and upregulated mRNA levels of IL-1β, TNF, IL-6, and CXCL1 (P<0.05). Compared with those in the model group, all the above indicators were reversed in the KXJD group (P<0.05). MTX only downregulated the expression of p-TRPV1 and PAR-2 (P<0.05), with no significant effects on the expression of NGF, p-TrkA, or CGRP. ConclusionKXJD inhibits the NGF-TrkA/TRPV1-PAR-2 signaling pathway to reduce neuropeptide release and simultaneously downregulates the p38 MAPK/NF-κB signaling pathway and the expression of downstream pro-inflammatory factors to ameliorate psoriasis-like neuroinflammation and immuno-inflammation. The therapeutic effect of KXJD on psoriasis-like inflammation is closely associated with the inhibition of the NGF-TrkA/TRPV1-PAR-2 signaling pathway. This study provides experimental evidence for the modern interpretation of the Xuanfu theory.

Objective:
This study aimed to construct an animal model of heart failure with preserved ejection fraction (HFpEF) that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis and to evaluate it comprehensively.
Methods:
The HFpEF mouse model was constructed using a combination of Nω-nitro-L-arginine methyl ester (L-NAME) and a high-fat diet. According to the random number table method, SPF-grade male C57BL/6J mice were randomly assigned to the control, L-NAME, high-fat diet, and model groups, 10 in each group. Comprehensive observations and data collection on macroscopic signs (e.g., fur condition, mental state, stool and urine, oral and nasal condition, paw and body condition, etc.) and cardiac function were performed after 10 and 16 weeks of model induction. Additionally, the syndrome evolution was elucidated based on diagnostic criteria for clinical syndromes of heart failure. Furthermore, pathological and molecular biological examinations of myocardial tissue were performed to assess the stability and reliability of the model.
Results:
Mice in the model group showed typical characteristics of syndrome of qi deficiency and blood stasis, as well as syndrome of internal heat accumulation, including lethargy, slow response, dull paw color and oral/nasal color, exercise intolerance, abnormal platelet activation, dry feces, and dark yellow urine. The time window for these syndromes was between 10 and 16 weeks post-modeling. Cardiac function assessments revealed severe diastolic dysfunction, concentric myocardial hypertrophy, and myocardial fibrosis in the model group. Pathological examinations showed a significantly increased collagen deposition in the myocardial interstitium, enlarged cross-sectional area of cardiomyocytes, and sparse coronary microvasculature in the model group. Molecular biological analyses indicated marked activation of the inducible nitric oxide synthase/nuclear factor kappa-light-chain-enhancer of activated B cells/NOD-like receptor family pyrin domain containing 3 inflammatory pathway and significantly elevated inflammation levels in the myocardial tissue of the model group. Although mice in the L-NAME and high-fat diet groups also showed certain manifestations of qi deficiency syndrome, the substantial cardiac damage was relatively limited compared to the control group.
Conclusion
This study has constructed an animal model of HFpEF that integrates disease and syndrome based on the "deficiency-blood stasis-toxin" pathogenesis. The macroscopic and microscopic characteristics of this model are consistent with the manifestations of syndrome of qi deficiency and blood stasis, toxin syndrome, and syndrome of internal heat accumulation. Moreover, it can stably simulate the HFpEF state and reflect phenotypic changes in human disease. This model provides a suitable experimental platform to explore the pathogenesis of HFpEF, evaluate the effectiveness of traditional Chinese medicine (TCM) treatment regimens, and promote in-depth research on TCM syndromes of heart failure.

ObjectiveTo construct a comprehensive evaluation indicator system for clinical practice guidelines of traditional Chinese medicine (TCM) that is scientific, systematic, and reflects the characteristics of TCM. MethodsA systematic search was conducted in Chinese and English databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, and Cochrane Library, to include literature on domestic and international guideline evaluation tools and TCM-related research. Document analysis and CiteSpace were utilized for keyword co-occurrence and clustering analysis. ResultsA total of 65 relevant studies were included, from which seven core thematic domains were identified. Based on the research objectives, a two-step construction strategy was adopted: first, an external evaluation framework was established by referencing international tools to cover methodological rigor and procedural standardization; second, an internal evaluation framework was developed to reflect the distinctive features of TCM clinical practice, including syndrome differentiation and efficacy feedback. Through expert consensus, the indicator system was refined, resulting in a dual-layered structure comprising 8 primary indicators, 22 secondary indicators, and 62 evaluation criteria. ConclusionThe comprehensive evaluation system for TCM clinical practice guidelines, based on bibliometric analysis and core element extraction, integrates both theoretical integrity and practical applicability. This study provides a preliminary research foundation for further optimization, validation, and development of a refined comprehensive evaluation system.

Salvia miltiorrhiza (Danshen) is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits. Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis, thereby affecting Helicobacter pylori (HP) colonization in the human stomach. HP is a bacterial pathogen associated with various gastrointestinal diseases. Current HP treatments mainly involve antibiotics and proton pump inhibitors. However, their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients. The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment. Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP, as well as the underlying mechanisms, is important for improving human gastrointestinal healthcare. This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science, PubMed, and Google Scholar. We explored the unconventional intersection between Danshen, gut microbiota, and HP infection, shedding light on their intricate interplay and potential therapeutic implications. A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.
