ObjectiveTo construct a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. MethodsLiterature related to Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease was retrieved from CNKI, VIP, and Wanfang databases. Diagnostic information from four diagnostic methods was extracted and standardized, with items having a frequency of ≥15 included in the item pool. A three-round Delphi expert consultation was conducted, screening items using support degree, mean score, rank sum, and coefficient of variation. Item weights were determined using analytic hierarchy process (AHP), gactor analysis (FA), and combined weighting method (CWM). The optimal weighting method was selected by comparing the area under the receiver operating characteristic (ROC) curve (AUC). The Youden index was calculated to establish the diagnostic cutoff value, which was proportionally scaled. ResultsA total of 102 studies were included. Thirty-five items were incorporated into the item pool. The authority coefficients for the three Delphi rounds were 0.82, 0.85, and 0.86, with coordination coefficients of 0.648, 0.538, and 0.506, respectively. Fifteen items were retained after screening. ROC curve analysis showed the AUC ranking as FA > CWM > AHP. The maximum Youden index was 0.814, corresponding to a diagnostic cutoff of 8.361 (scaled to 40 points). The final scale adopted a structured diagnostic framework: the symptom dimension requires at least 2 items, and the tongue or pulse dimension requires at least 1 category. ConclusionThis study developed a standardized diagnostic scale for Qi-Yin deficiency with blood stasis syndrome in diabetic macrovascular disease. Core items were screened via the Delphi method, with factor analysis identified as the optimal weighting method through AUC comparison. The diagnostic threshold (40 points) and structured diagnostic framework provide a quantitatively clear, clinically practical tool.

ObjectiveTo explore the establishment of a rat model of diabetic macrovascular atherosclerosis (DMA) with Qi and Yin deficiency syndrome induced by high-fat diet, streptozotocin (STZ), and Yin-depleting herbs, and to evaluate its biological characteristics. MethodsForty SD rats were randomly divided into a blank group (n=10) and a modeling group (n=30). Except for the blank group, rats in the model group were fed a high-fat diet for 4 weeks, followed by intraperitoneal injection of STZ (30 mg·kg-1) to establish a diabetic model. Twenty-four successfully modeled diabetic rats were randomly divided into a model group (n=7), a Qi and Yin deficiency syndrome group (n=8), and a counter-syndrome group (n=9). Except for the model group, rats received intragastric administration of Yin-depleting herbs (1.2 g·kg-1) for 8 weeks. The counter-syndrome group was further treated with Shenqi compound formula (1.69 g·kg-1) for an additional 8 weeks. General condition and body weight were recorded, and syndrome-related indicators were assessed, including precordial temperature, skin moisture content, grip strength, open-field test performance, and tongue appearance. Serum levels of vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), vascular cell adhesion molecule-1 (VCAM-1), insulin-like growth factor-1 (IGF-1), and monocyte chemotactic protein-1 (MCP-1) were measured by enzyme-linked immunosorbent assay (ELISA). Fasting blood glucose, blood lipids, hemorheological parameters, and coagulation function were analyzed using an automatic biochemical analyzer. Vascular ultrasound and hematoxylin-eosin (HE) staining were used to evaluate vascular lesions. ResultsIn terms of syndrome manifestations, compared with the blank group, body weight increased rapidly during the first 5 weeks in the model, Qi and Yin deficiency, and counter-syndrome groups. After STZ injection combined with Yin-depleting herbal administration at week 5, body weight decreased significantly (P<0.01) and continued to decline until the end of the experiment. Rats exhibited decreased activity, irritability, coarse and yellowish fur with obvious shedding, polydipsia, polyphagia, frequent urination, and dry stools, which were most pronounced in the Qi and Yin deficiency group. Grip strength decreased, peak activity time occurred earlier, total distance in the open-field test was reduced, and residence time was prolonged. Precordial temperature decreased (P<0.01), while paw temperature increased (P<0.05), and skin moisture and oil content were reduced (P<0.05, P<0.01). In terms of disease-related indicators, compared with the blank group, fasting blood glucose was significantly increased (>16.7 mmol·L-1) in the model and Qi and Yin deficiency groups, and blood lipid levels were significantly elevated (P<0.05). Vascular-related factors ET-1, MCP-1, VCAM-1, and VEGF were significantly increased (P<0.05,P<0.01), while IGF-1 was significantly decreased (P<0.01). Pathological examination of the aortic valve showed valvular thickening and structural disorganization. Carotid artery examination revealed discontinuity of the intima, foam cell accumulation beneath the intima, disordered smooth muscle arrangement, and widened intercellular spaces. Compared with the model group, ET-1, MCP-1, and VEGF levels were significantly decreased in both the Qi and Yin deficiency group and the counter-syndrome group. The reductions in ET-1 and MCP-1 were more pronounced in the Qi and Yin deficiency group (P<0.01), while the decrease in VCAM-1 was more significant in the counter-syndrome group (P<0.05). Compared with the blank group, the Qi and Yin deficiency group showed significantly prolonged activated partial thromboplastin time (APTT), thrombin time (TT), and prothrombin time (PT) (P<0.01). The erythrocyte deformability index (TK), erythrocyte sedimentation rate, erythrocyte electrophoresis index, and whole blood low-shear viscosity all showed increasing trends. Vascular ultrasound revealed reduced arterial blood flow velocity, increased vascular resistance, and intimal thickening without plaque formation. The aortic intima showed no obvious overall thickening, with only occasional localized thickening and foam cell presence, and carotid artery injury was observed. ConclusionA rat model of DMA with Qi and Yin deficiency syndrome was successfully established using high-fat diet feeding combined with STZ injection and Yin-depleting herbal administration. Shenqi compound formula effectively alleviated Qi and Yin deficiency syndrome, regulated glucose and lipid metabolism, improved hemorheological and coagulation function, reduced vascular lesion severity, and demonstrated potential for early prevention and treatment of DMA.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca2+ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca2+ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

Objective To optimize the process conditions and analyze the components of alkaloids from Zanthoxylum bungeanum Maxim(Z. bungeanum)using macroporous resin. Methods Combining single factor tests and orthogonal tests, the content of hydroxy-α-sanshool(HAS)and hydroxy-β-sanshool(HBS)were considered as indexes to determine the best process parameters. Ultra-performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry(UPLC-Q-TOF-MSE)was used to identify the structures of alkaloids. Results The optimal conditions were Mitsubishi HP-20 macroporous resin, the loading solution concentration was 0.2 g crude drug/ml, the ratio of crude drug to resin volume was 1 g∶2.5 ml, the diameter/height ratio of resin column was 1∶7, the dynamic adsorption flow rate was 4 times of bed volume(BV)per hour, and the adsorption time was 1 h. Impurities were removed by using 2 BV of 20% ethanol, 5 BV of 80% ethanol was used to elution, and the content of HAS and HBS was 4.71% and 1.02%, respectively. A total of 20 alkaloids were identified from Z. bungeanum. Conclusion This method was stable and feasible, obtaining high purity and various kinds of alkaloids, which could be used for the enrichment and purification of alkaloids from Z. bungeanum.

During orthodontic treatment, clinical monitoring of patients is a crucial factor in determining treatment success. It aids in timely problem detection and resolution, ensuring adherence to the intended treatment plan. In recent years, digital technology has increasingly permeated orthodontic clinical diagnosis and treatment, facilitating clinical decision-making, treatment planning, and follow-up monitoring. This review summarizes recent advancements in digital technology for monitoring orthodontic tooth movement, related complications, and appliance-wearing compliance. It aims to provide insights for researchers and clinicians to enhance the application of digital technology in orthodontics, improve treatment outcomes, and optimize patient experience. The digitization of diagnostic data and the visualization of dental models make chair-side follow-up monitoring more convenient, accurate, and efficient. At the same time, the emergence of remote monitoring technology allows orthodontists to promptly identify oral health issues in patients and take corresponding measures. Furthermore, the multimodal data fusion method offers valuable insights into the monitoring of the root-alveolar relationship. Artificial intelligence technology has made initial strides in automating the identification of orthodontic tooth movement, associated complications, and patient compliance evaluation. Sensors are effective tools for monitoring patient adherence and providing data-driven support for clinical decision-making. The application of digital technology in orthodontic monitoring holds great promise. However, challenges like technical bottlenecks, ethical considerations, and patient acceptance remain.

Background/Aims:
Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA.
Methods:
We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival.
Results:
Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016).
Conclusions
The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

AIM: To identify the primary active components and underlying mechanisms of Yijing Decoction(YJD)in treating early diabetic retinopathy(DR)based on liquid chromatography-mass spectrometry and network pharmacology.METHODS: Active components of YJD were characterized through LC-MS. Components with optimal ADME(absorption, distribution, metabolism, excretion)properties were selected as key bioactive candidates. Network pharmacology approaches were employed to predict YJD-DR therapeutic targets. Protein-protein interaction(PPI)networks, gene ontology(GO)enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis were subsequently conducted to predict core targets and networks. Critical targets and pathways were experimentally validated through Western blot.RESULTS: Ten core therapeutic targets were identified, including TNF, Alb, EGFR, STAT3, PTGS2, ESR1, PPAR, MMP9, TLR4, and MAPK. YJD was related to cancer-related signaling, fluid shear stress and atherosclerosis, and neurodegenerative diseases, encompassing key biological processes such as inflammatory response regulation, programmed cell death activation, and enhanced cell migration. Furthermore, Western blot analysis confirmed that YJD significantly inhibited high glucose-induced phosphorylation of STAT3(P-STAT3/STAT3)and ERK(P-ERK/ERK)in rat retinal microvascular endothelial cells.CONCLUSION: This study revealed YJD's pharmacodynamical basis and its multi-component, multi-target, and multi-paths pharmacology. YJD exerts therapeutic effects on DR by coordinately regulating critical signaling pathways and alleviating intraocular inflammation, thus preserving retinal vascular endothelial cells, maintaining blood-retinal barrier integrity, and facilitating retinal neurovascular repair.

AIM: To predict diabetic retinopathy(DR)progression through macular layer thickness in diabetic patients detected by optical coherence tomography(OCT).METHODS: Retrospective study. The clinical data of 100 cases(200 eyes)of diabetic patients admitted to our hospital from January 2023 to September 2024 were collected. According to the international clinical DR classification, they were divided into the non-diabetic retinopathy(NDR)group with 32 cases(64 eyes), the non-proliferative diabetic retinopathy(NPDR)group with 38 cases(76 eyes), and the proliferative diabetic retinopathy(PDR)group with 30 cases(60 eyes). At the same time, 49 cases(98 eyes)of healthy controls whose age and gender were matched with those of the diabetic patients were collected as the normal group. All patients underwent OCT examination. The thickness changes of the retinal nerve fiber layer(RNFL), ganglion cell layer(GCL), inner plexiform layer(IPL), outer nuclear layer(ONL), photoreceptor cell layer and total retinal thickness(RT)in the subregions of the macular area were compared among the groups. The Eta coefficient was used to analyze the correlation between them and the severity of DR.RESULTS: The thickness of RNFL, GCL, IPL, ONL and photoreceptor cell layer in each sub-region and the average of macular area in the PDR group was significantly lower than that in the NDR and normal groups, while the average RT thickness was significantly higher than that in the NPDR, NDR and normal groups(all P<0.05). The thickness of RNFL(central area, upper inner and outer rings and lower inner and outer rings and average), GCL(upper inner and outer rings and lower inner and outer rings and average), IPL(upper inner ring), ONL(central, upper inner ring and lower inner ring)and photoreceptor cell layer(upper inner and outer rings and lower inner and outer rings and average)in macular area of the PDR group was significantly thicker than that in the NPDR group(all P<0.05). The thickness of RNFL, GCL, IPL, ONL and photoreceptor cell layer in each sub-region and the average of macular area in the NPDR group was significantly lower than that in the NDR and normal groups, while the average RT thickness was significantly thicker than that in the NDR and normal groups(all P<0.05). There was no statistically significant difference in the above indicators between the NDR group and the normal group(all P>0.05). The severity of DR was significantly correlated with the average thickness of RNFL, GCL, IPL, ONL, photoreceptor cell layer and RT in macular area(all P<0.001).CONCLUSION: OCT measurement of the thickness of RNFL, GCL, IPL, ONL, photoreceptor cell layer and RT in the macular area in the diabetic patients can evaluate the progression of DR.

OBJECTIVE To systematically investigate the changes of volatile components in Euphorbia wallichii after milk and wine processing, and preliminarily elucidate the material basis for reducing toxicity. METHODS Using headspace gas chromatography-mass spectrometry technology, the volatile components in raw E. wallichii, milk-processed E. wallichii, and wine- processed E. wallichii were isolated and identified, and the relative percentage content of each component was calculated by the peak area normalization method. Combining chemometric methods such as principal component analysis and orthogonal partial least- squares discriminant analysis, changes in volatile components in samples after milk and wine processing were compared. Differential components were screened. RESULTS A total of 66 volatile components were identified from the three samples, with the types of compounds primarily comprising alkanes, olefins, heterocycles and esters, among others. A total of 39, 24 and 36 volatile components were identified from raw E. wallichii, milk-processed E. wallichii, and wine-processed E. wallichii, respectively, with 10 components common to all three preparations. Compared with raw E. wallichii, the relative percentage of other components in milk-processed E. wallichii decreased, except for alkanes and esters. The relative percentage of alkanes, olefins, aldehydes and esters in wine-processed E. wallichii increased, but the contents of heterocyclic compounds, ketones, ethers and alcohols decreased. The results of chemometric analysis showed that the volatile components of raw and processed products were significantly different. A total of 5 kinds of differential components in milk-processed products and 3 kinds of differential components in wine-processed products were screened out. Among them, the relative percentage of potential toxic components such as linalool, octanal and 3-pentanone decreased significantly after processing(P<0.05). CONCLUSIONS Milk and wine processing may exert a toxicity-reducing effect by reducing the contents of toxic components such as linalool, octanal and 3-pentanonein E. wallichii.
