ObjectiveIn traditional Chinese medicine (TCM), the foundational doctrine that the eyes reflect the essence of the internal viscera establishes ocular observation as a cornerstone of diagnostic practice. Specifically, the morphological characteristics and coloration variations of the scleral microvasculature serve as critical clinical indicators for assessing the dynamic balance of Qi and Blood, as well as the pathological status of internal organs. Historically, however, TCM eye diagnosis has relied predominantly on the subjective clinical experience and visual acuity of individual practitioners, leading to inherent challenges in standardization and reproducibility. While automated computer-aided diagnostic systems offer a promising solution, existing vessel segmentation algorithms encounter significant domain-specific bottlenecks when applied to scleral imagery. These challenges primarily stem from the highly reflective and moist nature of the ocular surface, which generates severe reflective interference. Furthermore, the inherent low contrast of fine capillary networks against complex background textures, compounded by non-uniform illumination, frequently results in high false-positive rates, misdetections, and severe vessel fragmentation. To address these critical limitations and advance the objective quantification of TCM diagnostics, this paper proposes a novel, highly robust sclera vessel segmentation framework that innovatively integrates Frangi-Sato dual-filter adaptive enhancement with pixel-level reflection detection. MethodsThe proposed methodology systematically addresses the segmentation pipeline through three synergistic stages. First, to overcome the structural limitations of single-filter approaches, a multi-scale weighted fusion strategy is meticulously designed to harness the complementary extraction capabilities of both Frangi and Sato filters. This adaptive enhancement optimally balances the preservation of main vessel trunk continuity with the heightened sensitivity required for delineating delicate, low-contrast peripheral capillaries. Second, to tackle the persistent issue of reflective highlights, a sophisticated multi-feature synergistic reflection detection module is introduced. By jointly analyzing local information entropy, gradient field variations, and intensity statistical distributions, this module achieves precise, pixel-level identification and elimination of reflective artifacts without compromising the underlying vascular structures. Finally, a dual-level adaptive thresholding strategy, featuring an innovative “core protection” mechanism, is implemented. This critical step effectively suppresses complex background noise while rigorously preserving the structural and topological integrity of the intricate vessel network, preventing the structural breaks often seen in conventional binarization methods. ResultsThe efficacy of the proposed framework was rigorously evaluated using both self-constructed clinical datasets specifically acquired for TCM research and standardized public datasets. Extensive experimental results demonstrate that the proposed method consistently outperforms state-of-the-art traditional approaches and contemporary deep learning models. Specifically, the proposed method achieves a Dice similarity coefficient of approximately 0.71 on the private clinical dataset, and secures the best performance across the majority of quantitative metrics on both datasets. Notably, the framework exhibits exceptional robustness and generalization capabilities in highly challenging scenarios characterized by intense reflective interference, low signal-to-noise ratios, and cross-domain image variations. ConclusionThis study successfully realizes the high-integrity, automated segmentation of scleral vessel networks under complex clinical imaging conditions. By overcoming the fundamental algorithmic challenges of reflection interference and micro-vessel loss, the proposed methodology provides potential support for the digitization, objective standardization, and intelligent advancement of modern TCM eye diagnosis systems.

ObjectiveTo observe the clinical efficacy and safety of Huatan Quyu formula in treating cerebral small vessel disease (CSVD) with phlegm and blood stasis blocking collateral pattern via randomized controlled trial, and explore its mechanism of improving CSVD by regulating glymphatic system (GS) circulation. MethodsSixty-eight CSVD patients with phlegm and blood stasis blocking collateral pattern in the Department of Encephalopathy, Affiliated Hospital of Shaanxi University of Chinese Medicine from April to December 2024 were selected and randomly divided into an experimental group (34 cases) and a control group, with 34 cases in each group. Both groups received basic Western medicine treatment, while the experimental group additionally received Huatan Quyu formula. After a course of 12 weeks, the following parameters were compared between the two groups before and after treatment. Clinical outcomes were assessed using the Tinetti performance-oriented mobility assessment (POMA), Montreal Cognitive Assessment (MoCA), Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT), and traditional Chinese medicine (TCM) syndrome scores of phlegm and blood stasis blocking collateral pattern. Perivascular space (PVS) in the frontal lobe/basal ganglia and cerebrospinal fluid (CSF) flow parameters in the cerebral aqueduct were evaluated by 3.0T brain MRI, cerebrospinal fluid flow imaging, and phase-contrast magnetic resonance imaging (PC-MRI). Then, safety indicators were monitored, and SPSS 25.0 was used for statistical analysis. ResultsSixty-four patients completed the study (32 in each group). ①Baseline data: No statistically significant difference was found between the two group. ②Efficacy indicators: After treatment, the experimental group exhibited significantly improved total POMA, SCOPA-AUT, and TCM syndrome scores (P<0.01), outperforming the control group (P<0.05). No significant change was observed in MoCA scores between the two groups. ③Imaging indicators: The experimental group showed a reduced PVS area alongside significantly increased CSF flow parameters (including downward flow during the systolic period, and upward flow during the diastolic period) (P<0.01), which were superior to the control group (P<0.01). ④Safety: The laboratory indicators were normal in both groups, with no drug-related adverse reactions. ConclusionFor CSVD patients with phlegm and blood stasis blocking collateral pattern, Huatan Quyu formula can safely and effectively improve motor function, autonomic nerve function, and TCM syndromes, with potential mechanisms related to pulsatile CSF flow enhancement and GS circulation efficiency improvement.

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.

Objective: To systematically analyze the current status and influencing factors of platelet supply in medical institutions across China, and to explore the problems and future development directions of the existing supply models. Methods: From February 25 to March 5, 2025, a web-based questionnaire survey was performed. A self-designed questionnaire was distributed to staff in the blood transfusion departments of medical institutions nationwide in China. Data on the current status and influencing factors of platelet supply were collected and analyzed. Results: A total of 2 268 responses were collected in this survey, with 1 366 valid questionnaires finally included, covering 33 provinces, autonomous regions, and municipalities directly under the central government across China. The survey revealed that platelet supply in Chinese medical institutions exhibited a pattern of "sufficient in the eastern region, stable in the central region, and scarce in the western region": adequate in East China; generally favorable in South China except Guangxi; centered on Beijing and Tianjin in North China; basically met but with insufficient reserves in Central China; subject to seasonal fluctuations in Northeast China; only meeting the baseline supply in Yunnan, Guizhou, and Sichuan in Southwest China; and notably short in Qinghai, Ningxia, and Xinjiang in Northwest China. Family donor mobilization was required in 81.2% (1 109/1 366) of institutions, whereas this proportion was only 12.7% (173/1 366) among institutions with sufficient supply. Tertiary hospitals constituted the main users, among which tertiary Class A hospitals had the highest sufficiency rate, and secondary Class B hospitals showed the most pronounced shortage. A total of 84% (1 147/1 366) of institutions lacked a professional management team; only 19% (266/1 366) had an inventory warning system, of which 88% (234/266) considered it effective. Platelet reservation required 3 days in 33% (458/1 366) of institutions. The mandatory transfusion rate was 30.55% (29/118) when the reservation lead time exceeded 3 days, representing an increase of 5.98% compared with 24.57% (55/180) in the same-day reservation group. For optimization, most institutions called for improved blood donation services, strengthened education and incentives, establishment of regional coordination and policy collaboration, and supplementary suggestions focused on technologies for extending platelet shelf life. Conclusion: Regional imbalance in platelet supply across China is prominent, with supply shortages in some provinces, reliance on family donor mobilization in most institutions, weak grassroots support capacity, imperfect management systems, and supply timeliness constraining clinical practice. Systematic improvements are needed in optimizing blood donation services, strengthening regional coordination, improving relevant policies, and developing platelet preservation technologies, so as to enhance the level of supply security and patient safety.

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.
