ObjectiveTo establish an ultra-performance liquid fingerprint and multi-components determination method for Naomaili granules. To evaluate the quality of different batches by chemometrics, and the anti-neuroinflammatory effects of water extract and main components of Naomaili granules were tested in vitro. MethodsThe similarity and common peaks of 27 batches of Naomaili granules were evaluated by using Ultra performance liquid chromatography (UPLC) fingerprint detection. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology was used to determine the content of the index components in Naomaili granules and to evaluate the quality of different batches of Naomaili granules by chemometrics. LPS-induced BV-2 cell inflammation model was used to investigate the anti-neuroinflammatory effects of the water extract and main components of Naomaili granules. ResultsThe similarity of fingerprints of 27 batches of samples was > 0.90. A total of 32 common peaks were calibrated, and 23 of them were identified and assigned. In 27 batches of Naomaili granules, the mass fractions of 14 components that were stachydrine hydrochloride, leonurine hydrochloride, calycosin-7-O-glucoside, calycosin,tanshinoneⅠ, cryptotanshinone, tanshinoneⅡA, ginsenoside Rb1, notoginsenoside R1, ginsenoside Rg1, paeoniflorin, albiflorin, lactiflorin, and salvianolic acid B were found to be 2.902-3.498, 0.233-0.343, 0.111-0.301, 0.07-0.152, 0.136-0.228, 0.195-0.390, 0.324-0.482, 1.056-1.435, 0.271-0.397, 1.318-1.649, 3.038-4.059, 2.263-3.455, 0.152-0.232, 2.931-3.991 mg∙g-1, respectively. Multivariate statistical analysis showed that paeoniflorin, ginsenoside Rg1, ginsenoside Rb1 and staphylline hydrochloride were quality difference markers to control the stability of the preparation. The results of bioactive experiment showed that the water extract of Naomaili granules and the eight main components with high content in the prescription had a dose-dependent inhibitory effect on the release of NO in the cell supernatant. Among them, salvianolic acid B and ginsenoside Rb1 had strong anti-inflammatory activity, with IC50 values of (36.11±0.15) mg∙L-1 and (27.24±0.54) mg∙L-1, respectively. ConclusionThe quality evaluation method of Naomaili granules established in this study was accurate and reproducible. Four quality difference markers were screened out, and eight key pharmacodynamic substances of Naomaili granules against neuroinflammation were screened out by in vitro cell experiments.

Pan vascular disease (PVD) is a systemic vascular disorder that has become the leading cause of death among the Chinese residents, and there is currently a lack of effective systemic treatment options. Clinical practice has found that the traditional Chinese medicine (TCM) method of kidney tonification can effectively intervene in PVD and target key pathological mechanisms of PVD recognized in Western medicine. Accordingly, this paper conducts research from the following three aspects: First, it clarifies that immune dysregulation, metabolic disorders, and genetic susceptibility constitute the core pathological mechanisms of PVD in Western medicine. Typical pathological manifestations include progressive vascular endothelial injury, lipid deposition, and plaque formation, ultimately leading to multi-organ damage and dysfunction. PVD activates pathways such as the NOD-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome, triggering immune dysregulation; it also induces disorders of mitochondrial energy metabolism, water-salt metabolism, and hormonal metabolism, synergizing with genetic susceptibility factors (e.g., apolipoprotein E gene) to accelerate vascular homeostasis imbalance. Second, this study analyzes the intrinsic relationship between the TCM theory of "kidney deficiency" and the "immune-metabolic-genetic" axis, revealing the theoretical basis for kidney tonification in intervening PVD. The kidney stores essence, governs bones, and produces marrow, which is related to the generation and differentiation of immune cells. It regulates Qi transformation and governs water, overseeing material and energy metabolism. The kidney is the root of congenital essence and governs reproduction, closely related to genetic mechanisms. Third, by integrating modern clinical research, this study elaborates on the unique advantages and clinical value of kidney tonification in targeting the "immune-metabolic-genetic" axis of heart, brain, and kidney organs. Traditional kidney-tonifying formulas and their active ingredients improve immune-inflammatory responses, enhance material and energy metabolism homeostasis, and modulate epigenetic pathways through multiple pathways, targeting various pathways to intervene in PVD. This study systematically elucidates the scientific connotation of kidney tonification in treating PVD, providing theoretical support and practical guidance for integrated TCM-Western medicine approaches and contributing to innovation and improvement in diagnostic and treatment strategies for PVD.

ObjectiveTaking Aurantii Fructus Immaturus juice(AFI)-processed Atractylodis Macrocephalae Rhizoma(AMR) as an example, this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products, investigate the key differential components, evaluate their anti-inflammatory activities, and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry(GC-MS) and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology(NIST)17 database, comparison with retention index(RI) and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine (TCM) spectral library, in conjunction with PubChem and MassBank, characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA), with variable importance in the projection(VIP) value >1. Components with high log2fold change(FC) among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide(NO) production in a lipopolysaccharide(LPS)-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay(ELISA) was used to detect the effects of the differential components on tumor necrosis factor(TNF)-α, interleukin(IL)-1β, IL-6, and monocyte chemotactic protein(MCP)-1 levels, and immunofluorescence(IF) was employed to assess their effects on nuclear transcription factor(NF)-κB p65 translocation, thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR, among which, sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components, 36 compounds were identified, and the main differential components were flavonoids, sesquiterpenoids, and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products, representing compounds directly introduced during processing. Five compounds, including atractylenolide Ⅲ, tangeritin, nobiletin, hesperidin and narirutin, were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L-1 tangerine and narirutin could significantly inhibit LPS-induced NO production(P<0.01) in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7(P<0.05), while narirutin significantly inhibited the levels of TNF-α, IL-1β, MCP-1 and IL-6(P<0.01). IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR, and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.

ObjectiveTo investigate the current situation of mutual recognition for ethical review outcomes in multicenter clinical research across 10 contracting medical institutions in Guangdong Province, analyze existing issues and propose improvement recommendations, thereby promoting the standardized management of mutual recognition for ethical review outcomes in medical institutions. MethodsData from 381 multicenter clinical studies conducted in these 10 medical institutions from January 24 to October 31, 2024, were collected. Text visualization was performed using Python and the WordCloud library, and statistical analyses were conducted with SPSS 25.0. ResultsOf the 381 studies investigated, industry-sponsored clinical trials (ISTs) accounted for 51.71%, while investigator-initiated clinical trials (IITs) constituted 48.29%. The proportions of ethical committees serving as primary reviewers and collaborative reviewers were 33.33% and 66.67%, respectively. The confirmation methods of mutual recognition outcomes were primarily expedited reviews (50.66%) and meeting reviews (49.34%), and no cases of “direct confirmation” were found. The Chi-square test revealed statistically significant differences in review confirmation methods based on project type (χ²=14.851, P<0.001) and ethics committee role (χ²= 69.435, P<0.001). The frequency distribution trend of the contingency table showed that IST projects and primary ethics committees preferred to employ meeting review (58.88% and 79.53% respectively, both higher than the average level of 49.34%), while IIT projects and the collaborative ethics committees more frequently utilized expedited review (60.87% and 65.75% respectively, both higher than the average level of 50.66%). ConclusionThe confirmation methods of mutual recognition for ethical review outcomes in multicenter clinical research are significantly associated with the role of the ethics committee and the type of project. It is recommended to improve management systems, enhance information construction and personnel training, as well as clarify mutual recognition responsibilities and strengthen supervision. This aims to ensure review quality while improving mutual recognition efficiency, thereby safeguarding the rights and interests of research participants.

ObjectiveTo investigate the mechanism of salt processing of Psoraleae Fructus (PF) through modern analytical techniques and biotechnology, focusing on its effects related to hepatotoxicity and anti-osteoporosis activity. MethodsThe zebrafish model was utilized to evaluate the impact of PF and salt-processed Psoraleae Fructus (SPF) on the hepatotoxicity (using 134.17 , 178.89, 268.34 mg·L-1 as low, medium, and high dose groups of PF, 135.04, 180.06, 270.08 mg·L-1 as low, medium, and high dose groups of SPF, respectively) and anti-osteoporotic activity (using 33.54 , 67.08 and 134.17 mg·L-1 as low, medium, and high dose groups of PF, 33.76, 67.52, 135.04 mg·L-1 as low, medium, and high dose groups of SPF, respectively), which was using alizarin red skull staining of zebrafish as an indicator of different batches of PF. The specific dosage of a batch of PF was taken as an example. Then ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry(UPLC-Q-TOF-MS) analysis was employed to identify the chemical composition of PF before and after salt processing, and PCA, OPLS-DA, and independent sample t-test were used to elucidating the compositional changes associated with the effects of salt processing on hepatotoxicity and anti-osteoporosis activity. ResultsUnder specific conditions, PF induced notable hepatotoxicity in zebrafish while simultaneously demonstrating protective effect against prednisolone-induced osteoporosis. In comparison to PF, SPF showed alleviated hepatotoxicity while retaining significant anti-osteoporosis activity. UPLC-Q-TOF-MS analysis revealed that after salt processing, the overall chemical composition of PF showed a downward trend, with 69 components showing a decrease in content, represented by psoralen, and 13 components showing an increase, represented by 4′-O-methyl psoralen B. Further multivariate statistical analysis revealed 11 key differential components before and after salt processing of PF, including psoralen and bakuchiol. ConclusionSalt processing effectively diminishes hepatotoxicity without impairing therapeutic efficacy against osteoporosis of PF, which may be related to the compositional changes before and after salt processing of PF and provides key evidence to reveal the scientific significance of salt processing of PF.

Objective To explore the wearing status and actual noise reduction effect of hearing protectors among noise workers in a typical automobile manufacturing enterprise. Methods In April 2024, an occupational hazard factor testing was carried out in an automobile manufacturing industry, and at the same time, the hearing protection fit test was conducted for noise workers. Intervention and guidance were provided to those who did not pass the minimum standard of baseline PAR. The difference in PAR between baseline and post-intervention was compared, and the effectiveness of hearing protector wearing method training was evaluated. Results The exceeding rate of the company's noise operation post was 50.77% (66/130). The baseline PAR of the subjects with working experience of less than 15 years and wearing hearing protectors throughout noisy work was higher, and the differences were statistically significant (P<0.05). Compared with those with 80dB≤LEX, 8h<85dB, more research subjects with LEX, 8h≥85dB failed baseline PAR (39.13%). After intervention, the PAR of the subjects who did not pass the minimum standard of baseline PRA increased from 2.0 (0.0, 5.3) to 17.0 (14.8, 20.0), and the protection level was significantly improved, and the difference was statistically significant (P<0.01). Conclusion The individual fit test of hearing protector is an important means to evaluate the actual noise reduction level of hearing protector and guide the selection of hearing protection models. Corporate training can help improve the PAR of hearing protectors.

ObjectiveThis paper aims to explore the in vitro anti-psoriasis activity and potential mechanism of Kangfuxin liquid (KFX liquid), providing experimental evidence for the anti-psoriasis effect of KFX liquid. MethodsFirstly, the uninduced human immortalized keratinocyte cells (HaCaT cells) were divided into seven groups, namely the control group and KFX liquid groups with different doses (5, 10, 20, 40, 80, 160 g·L-1). After being treated with different concentrations of KFX liquid, the effect of KFX liquid on the normal cell proliferation was detected by using the cell counting kit-8 (CCK-8) method. Secondly, the uninduced HaCaT cells were divided into six groups, namely the control group and recombinant human interleukin-7A (rh-IL-7A) groups with different doses (5, 10, 50, 100, 120 g·L-1). After being treated with different concentrations of recombinant human interleukin-17A (rh IL-17A) liquid, the effect of rh IL-17A on cell proliferation was detected. The optimal induction concentration was screened. Then, normal HaCaT cells were divided into a control group and KFX liquid groups with different doses (5, 10, 20, 40, 80, 160 g·L-1). Except for the control group, the other groups established psoriasis cell models with the optimal induction concentration of rh IL-17A. After being treated with different concentrations of KFX liquid, the effects of KFX liquid on the psoriasis-like HaCaT cell proliferation were investigated. Finally, the uninduced HaCaT cells were divided into six groups, namely the control group, rh IL-17A group, methotrexate (MTX) group, and KFX liquid groups with different doses (20, 40, 80 g·L-1). Except for the control group, the other groups used the optimal induction concentration of rh IL-17A to establish psoriasis cell models. After being treated with different drugs, the cell migration levels were detected through scratch assays, and real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the relative mRNA expression levels of Ki-67 antigen (Ki67), S100 calcium-binding protein A7 (S100A7), S100 calcium-binding protein A8 (S100A8), and S100 calcium-binding protein A9 (S100A9), thereby comprehensively evaluating the in vitro anti-psoriasis activity of KFX liquid. By detecting the relative mRNA expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and chemokine-20 (CXCL-20) inflammatory-related factors in psoriasis-like HaCaT cells and the protein expression levels of Janus kinase 3 (JAK3), phosphorylated Janus kinase 3 (p-JAK3), signal transducer and activator of transcription 3 (STAT3), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3), the mechanism was explored. ResultsCompared with that of control group, when treated with 80 g·L-1 KFX liquid for 72 h (P<0.05) and at different times with 160 g·L-1 KFX liquid, the HaCaT cell proliferation activity was significantly affected (P<0.01), while the other concentrations of KFX liquid had no significant differences in cell morphology and cell proliferation activity at different times, indicating that the KFX liquid is relatively safe for HaCaT cells and has no obvious toxic side effects. Compared with that of control group, when treated with different concentrations of rh IL-17A for 24 h, the HaCaT cell proliferation activity was significantly enhanced, and the cell activity was the strongest when the concentration was 100 μg·L-1 (P<0.05), with a density close to 100% and intact cell morphology, indicating that 100 μg·L-1 is the optimal concentration for inducing HaCaT cell proliferation. The results of the KFX liquid treatment on rh IL-17A-induced psoriasis-like cells show that the KFX liquid not only effectively inhibits the rh IL-17A-induced psoriasis-like HaCaT cell proliferation activity (P<0.01), but also significantly reduces the migration ability of rh IL-17A-induced psoriasis-like HaCaT cells (P<0.01), and the relative mRNA expression levels of Ki67, S100A7, S100A8, and S100A9 (P<0.01). Moreover, the KFX liquid can significantly reduce the relative mRNA expression levels of IL-1β, IL-6, and CXCL-20 in rh IL-17A-induced psoriasis-like cells (P<0.01), and significantly inhibit the phosphorylation levels of JAK3 and STAT3 proteins (P<0.05, P<0.01). ConclusionThe KFX liquid has no obvious toxicity to uninduced HaCaT cells. It can inhibit rh IL-17A-induced psoriasis-like HaCaT cell proliferation, reduce the cell migration ability, and has good in vitro anti-psoriasis activity. Its action mechanism may be related to downregulating the expression levels of inflammation-related cytokines in the JAK3/STAT3 signaling pathway and inhibiting the phosphorylation levels of JAK3 and STAT3 proteins.

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.

Angiogenesis, as a core mechanism for maintaining tissue perfusion and repairing ischemic injury, plays a crucial role in ischemic diseases such as coronary heart disease and peripheral arterial disease. Traditional Chinese medicine(TCM), with its advantages of multi-target and synergistic regulation, provides a unique perspective for therapeutic angiogenesis. Based on this, this article intends to delve into the synergistic effects of key signaling pathways, including vascular endothelial growth factor(VEGF)/VEGF receptor(VEGFR), Notch, phosphoinositide 3-kinase/ protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR), and angiopoietin/endothelial TEK tyrosine kinase(Ang/Tie2), and elucidate the driving mechanisms of endothelial cell metabolic reprogramming and exosome-mediated intercellular communication within this process. Based on existing literature, it summarizes the microenvironment-dependent and bidirectional regulatory characteristics of natural active components of TCM(such as terpenes, tanshinones, and flavonoids) on angiogenesis. Furthermore, it systematically discusses how classical TCM formulas achieve blood vessel formation and functional maturation by protecting the neurovascular units, recruiting pericytes, and remodeling the microenvironment. Current evidence highlights the advantages of multi-target synergy and temporal regulation in TCM, but also reveals challenges such as high heterogeneity and a lack of functional evaluations and high-quality clinical trials. Future efforts should integrate multi-omics to decipher network mechanisms, optimize formula compatibility, and conduct multicenter studies to promote the development of innovative preparations. This review highlights the academic value of TCM in angiogenesis, provides an evidence base for treating ischemic diseases, and supports multidisciplinary integration and innovation.
