ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

OBJECTIVE To focus on the classic NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula (HQHF) inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis (MASH). METHODS RAW264.7 cells were divided into 5 groups: Control group (10% blank serum), Model group [10% blank serum+5 μg/mL lipopolysaccharide (LPS)], HQHF-L group (2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS), HQHF-M group (5% drug-containing serum+5% blank serum+5 μg/mL LPS), and HQHF-H group (10% drug-containing serum+5 μg/mL LPS). After 24 h of routine culture post-administration, cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy; localization and expression of gasdermin D-N (GSDMD-N) were observed by immunofluorescence. Interleukin-1β (IL-1β) and IL-18 contents in supernatants were detected by ELISA; mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group, the Model group showed typical pyroptotic morphology (cell membrane bulging and pore formation), increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane ( P <0.05), significantly increased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly up-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). Compared with the Model group, the HQHF-L, HQHF-M and HQHF-H groups showed improved pyroptotic morphology, reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N ( P <0.05), significantly decreased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly down-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis, and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

Objective:
To develop a prediction model for mild cognitive impairment (MCI) risk among the elderly, so as to provide a tool for MCI early screening.
Methods :
From July 2022 to September 2024, a multi-stage stratified random cluster sampling method was used to recruit permanent residents aged ≥65 years from the Xinjiang Uygur Autonomous Region as study participants. Data on sociodemographic characteristics, nutritional status, body composition indices, bone mineral density, and handgrip strength were collected through questionnaires and physical examinations. Sarcopenia was defined based on appendicular skeletal muscle index and handgrip strength. MCI was assessed using the Mini-Mental State Examination, with adjustments for educational level. Participants were randomly divided into a training set and a validation set in a 7∶3 ratio. LASSO regression and multivariable logistic regression models were employed to screen for predictors and construct an MCI risk prediction model. The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curve and decision curve analysis (DCA).
Results:
A total of 1 641 participants were surveyed, including 755 males (46.01%) and 886 females (53.99%). The majority of participants were aged 65-<75 years, comprising 1 154 individuals (70.32%). MCI was detected in 517 participants, corresponding to a detection rate of 31.51%. Resultsfrom LASSO regression and multivariate logistic regression analysis showed that residence (rural, OR = 2.323, 95% CI: 1.682-3.210), age (75-<85 years, OR = 1.405, 95% CI: 1.019-1.937; ≥85 years, OR = 3.655, 95% CI: 1.696-7.875), educational level (primary school, OR = 0.341, 95% CI: 0.247-0.472; junior high school, OR = 0.255, 95% CI: 0.160-0.408; high school, OR = 0.286, 95% CI: 0.154-0.531; bachelor's degree or above, OR = 0.120, 95% CI: 0.041-0.351), history of alcohol consumption (yes, OR = 3.216, 95% CI: 2.164-4.779), risk of malnutrition (yes, OR = 1.464, 95% CI: 1.064-2.014), sarcopenia (yes, OR = 3.197, 95% CI: 2.332-4.385), and waist-to-hip ratio (abnormal, OR = 1.540, 95% CI: 1.159-2.048) were identified as predictive factors for MCI among the elderly. In the training set, the area under the ROC curve, sensitivity, and specificity were 0.788, 0.719, and 0.712, respectively. In the validation set, the corresponding values were 0.784, 0.913, and 0.542, respectively. DCA demonstrated that the model provided a higher clinical net benefit for predicting MCI risk when the risk threshold probability ranged from 0.124 to 0.764.
Conclusion
The prediction model developed in this study demonstrates good discriminative ability and clinical utility, indicating its substantial value for predicting the MCI risk among the elderly.

The morphological characteristics and pathological progression of vulnerable plaques in atherosclerosis (AS) exhibit a high degree of similarity to the concept of "abscesses and ulcers" in traditional Chinese medicine (TCM). Therefore, vulnerable atherosclerotic plaques can be analogized as "abscesses and ulcers within the vessels", for which deficiency, stasis and toxin constitute the core pathogenesis. The pathological evolution progresses through three sequential stages, deficiency leading to pathological substances, with phlegm and stasis accumulating into a mass; the mass transforming into putridity, with internal decay and external thinning; putridity brewing toxin, and toxin accumulation threatening rupture, ultimately resulting in plaque instability. Accordingly, a stage-specific treatment strategy is established. In the early stage, it is suggested to supplement deficiency, resolve the mass, dissipate stasis, and prevent putridity, using Liujunzi Decoction (六君子汤) combined with Danshen Decoction (丹参饮) with modifications. In the middle stage, the treatment should focus on transforming putridity to generate new tissue, and rectifying healthy qi to consolidate the body, with modified Tuoli Xiaodu Powder (托里消毒散). In the late stage, the treatment principle is clearing and resolving putridity toxin, cooling the blood, and preventing ulcerative rupture, using modified Simiao Yong'an Decoction (四妙勇安汤) combined with Xijiao Dihuang Decoction (犀角地黄汤).

The development of atherosclerosis (AS) is closely associated with endothelial dysfunction and mitochondrial metabolic abnormalities. These alterations are fundamentally characterized by metabolic reprogramming, in which the tricarboxylic acid (TCA) cycle serves as a central regulatory hub. Disruption of the homeostasis of TCA cycle intermediates, including succinate, α -ketoglutarate, and itaconate, contributes to AS progression through multiple mechanisms, such as the modulation of oxidative stress, inflammation, and glucose and lipid metabolic networks. Owing to their multi-target and multi-pathway regulatory properties, bioactive compounds derived from traditional Chinese medicine (TCM) have demonstrated unique advantages in correcting metabolic dysregulation. Flavonoids, glycosides, and other bioactive constituents of TCM can target key enzymes and metabolites involved in the TCA cycle, thereby restoring aberrant metabolic reprogramming, alleviating endothelial injury induced by oxidative stress, inflammation, and glucose and lipid metabolic disorders, ultimately improving metabolic homeostasis and attenuating the progression of AS.

Through consulting herbal medicine, medical books, and local chronicles from past dynasties to modern times, this paper systematically researched Spatholobi Caulis from name, origin, producing areas, harvesting, processing, usage, quality evaluation, functions and indications, providing a reference for the development and utilization of famous classical formulas containing Spatholobi Caulis. According to the research, Spatholobi Caulis was first recorded in the Annals of Shunning Prefecture from the Qing dynasty. It was originally a medicinal herb commonly used in Shunning, Yunnan, and was named from the red juice resembling chicken blood that flowed out after the vein was cut off. The mainstream original plants of each dynasty were Kadsura heteroclita and Spatholobus suberectus. Among them, K. heteroclita mainly focused on dispersing blood stasis and unblocking meridians, mainly treating rheumatic pain and injuries caused by falls or blows, and it is mostly used as the raw material of Jixueteng ointments. S. suberectus was commonly used as decoction pieces in decoction, which had the functions of promoting blood circulation and replenishing blood, activating meridians and collaterals, and mainly used for treating anemia, irregular menstruation, and rheumatic bone pain. The production area of Spatholobi Caulis recorded in the Qing dynasty was Yunnan. Currently, the main production area of S. suberectus is Guangxi, while the main production area of K. interior is Yunnan. In the Qing dynasty, the usage of Spatholobi Caulis was an individual prescription with other herbs before making ointments, which was usually composed of the juice of it, safflower, angelica, and glutinous rice. But in modern times, Spatholobi Caulis is mostly sliced and dried for use. The quality of Spatholobi Caulis is often determined by the number of reddish-brown concentric circles on the cut surface, with a higher number indicating better quality. Additionally, the presence of resinous secretions is also considered desirable. Based on the research findings, it is suggested that when developing famous classical formulas containing Spatholobi Caulis, the choice of the primary source should be S. suberectus or K. heteroclita, taking into consideration the therapeutic effects of the formula. It is also recommended that the latest plant classification be referenced in the next edition of Chinese Pharmacopoeia, adjusting the primary source of Kadsurae Caulis to K. heteroclita to avoid confusion caused by inconsistent original names, and the functions adjust to promote Qi circulation and relieve pain, disperse blood stasis and unblock collaterals, treating injuries caused by falls and bruises.

ObjectiveTo investigate the mechanism of Huangqi Gegentang (HGT) in the treatment of type 2 diabetes mellitus (T2DM) through the application of proteomic techniques. MethodsThe rat model of T2DM was established by streptozotocin combined with a high-fat, high-sugar diet. Thirty-two male SD rats were randomized into four groups: blank, model, HGT (8.10 g·kg-1·d-1), and positive control (metformin hydrochloride, 76.5 mg·kg-1·d-1). After 6 weeks of drug intervention, the fasting blood glucose level was measured, and an oral glucose tolerance test (OGTT) was performed. The area under the curve (AUC) was calculated. Enzyme-linked immunosorbent assay was performed to assess the level of glycated hemoglobin (GHbA1c) in the serum. The limulus amebocyte lysate assay was employed to measure the serum level of lipopolysaccharide (LPS). Pathological changes in the colon were observed by hematoxylin-eosin staining. The mRNA levels of pro-inflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the colon tissue were quantified via Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). Additionally, the protein and mRNA levels of zonula occludens-1 (ZO-1), Occludin, and Claudin-1 in the colon tissue were assessed by Western blot and Real-time PCR, respectively. Label-free quantitative proteomics was employed to identify the differentially expressed proteins between the colon tissue samples from the blank, model, and HGT groups. Key proteins identified were subsequently validated by Western blot and Real-time PCR. Finally, bioinformatics analysis was conducted on the differentially expressed proteins. ResultsCompared with the blank group, the model group exhibited increased fasting blood glucose, AUC, and GHbA1c levels (P<0.01), damaged colonic mucosal epithelial structure and inflammatory cell infiltration, up-regulated mRNA levels of TNF-α, IL-6, and IL-1β in the colon and an increase in serum LPS content (P<0.05, P<0.01), and down-regulated protein and mRNA levels of ZO-1, Occludin, and Claudin-1 in the colon (P<0.01). Compared with the model group, the HGT group showed reductions in fasting blood glucose, AUC, and GHbA1c (P<0.01), alleviated damage to the colonic mucosal epithelium, down-regulated mRNA levels of TNF-α, IL-6, and IL-1β in the colon, a reduction in serum LPS content (P<0.05, P<0.01), and up-regulated protein and mRNA levels of ZO-1, Occludin, and Claudin-1 in the colon (P<0.05, P<0.01). Proteomics analysis identified 70 differentially expressed proteins that exhibited a downward trend in the model group relative to the blank group and an upward trend in the HGT group relative to the model group. These findings were corroborated by Western blot and Real-time PCR, which confirmed that the protein and mRNA levels of mucin 2 (Muc2) and transforming growth factor (TGF)-beta receptor 1 (Tgfbr1) in the colon tissue were consistent with the proteomic data. Bioinformatics analysis showed that these 70 differentially expressed proteins identified were significantly enriched in multiple signaling pathways, among which the TGF-β and advanced glycation endproduct (AGE)/receptor for advanced glycation endproduct (RAGE) signaling pathways were closely associated with damage to the intestinal mucosal barrier. This suggests that HGT may ameliorate intestinal mucosal barrier damage by regulating these pathways. ConclusionHGT potentially exerts anti-T2DM effects by influencing AGE/RAGE and TGF-β signaling pathways, thereby contributing to the restoration of the intestinal mucosal barrier.

ObjectiveTo investigate the association between serum creatinine/cystatin C ratio (CCR) and nonalcoholic fatty liver disease (NAFLD) based on the NHANES database, and to evaluate the potential significance of CCR as an indicator reflecting the metabolic status of the body. MethodsBased on the data from the NHANES database in 1999 — 2004, a total of 4 217 participants were enrolled and divided into NAFLD group with 1 726 participants and non-NAFLD group with 2 491 participants. CCR was compared between the two groups, and the association between CCR and NAFLD was analyzed. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression model was used to investigate the association between CCR and NAFLD; CCR was divided into 4 groups based on quartiles, and odds ratio (OR) and 95% confidence interval (CI) in the regression model was calculated with the first quartile as reference. In addition, the restricted cubic spline analysis was used to investigate whether there was a non-linear relationship between CCR and NAFLD, and interaction items were introduced into the Logistic regression model to perform an interaction analysis. Subgroup analyses were performed based on the stratification of variables to investigate the difference in the association between CCR and NAFLD in different populations. ResultsThe non-NAFLD group had a significantly higher CCR than the NAFLD group (Z=-4.76,P<0.01). The Logistic regression analysis showed that in model 1 without adjustment of variables, CCR was negatively associated with NAFLD (OR=0.993,95%CI:0.989 — 0.996,P<0.01), and in model 3 with adjustment of all variables, CCR was still negatively associated with NAFLD (OR=0.986,95%CI:0.981 — 0.991,P<0.01). The analysis of CCR based on quartiles showed a significant association between the increase in CCR and the reduction in the risk of NAFLD. In model 3, compared with the individuals with the lowest quartile of CCR, the individuals with the highest quartile of CCR had a significantly lower risk of NAFLD (OR=0.426,95%CI:0.316 — 0.574,P<0.01). Further interaction and subgroup analyses showed that the interaction between CCR and age/sex had a statistical significance (Pinteraction<0.01 and Pinteraction=0.04). The subgroup analysis based on age showed a more significant association between CCR and NAFLD in the middle-aged population (≤60 years) (OR=0.982,95%CI:0.976 — 0.987), and the subgroup analysis based on sex showed a stronger association between CCR and NAFLD in women (OR=0.979,95%CI:0.972 — 0.986). ConclusionThis study shows a significant negative association between CCR and NAFLD, and such association is more significant in middle-aged individuals and women.
