ObjectiveTo investigate the potential mechanism of Danggui Buxuetang (DBT) in the treatment of vascular dementia (VAD). MethodsSixty male SD rats were randomly assigned to the sham-operated group, model group, DBT low-, medium-, and high-dose groups, and the donepezil group. Except for the sham-operated group, rats in all other groups underwent bilateral common carotid artery ligation. After successful modeling, DBT was administered at doses of 9.2, 18.4, 36.8 g·kg-1 for the low-, medium-, and high-dose groups, respectively, while the donepezil group received 3 mg·kg-1 donepezil solution by gavage once daily. After 4 consecutive weeks of drug treatment, rats underwent the Morris water maze test, novel object recognition test, Nissl staining to observe hippocampal neurons, and immunofluorescence staining to detect the expression of neuronal nuclear protein (NeuN) in the hippocampus. Western blot was used to assess the expression of PTEN-induced kinase 1 (PINK1), Parkin, microtubule-associated protein 1 light chain 3Ⅱ (LC3Ⅱ), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax). Transmission electron microscopy was used to observe hippocampal neuronal ultrastructure. Real-time PCR was used to detect the expression of NADPH oxidase subunits p22phox and p47phox in hippocampal tissues. The levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and total antioxidant capacity were measured to evaluate oxidative stress levels. ResultsIn the Morris water maze test, escape latency changed significantly over time in all groups except the model group. Compared with the sham-operated group, the model group showed significantly prolonged escape latency (P<0.01). Compared with the model group, rats in the DBT groups and the donepezil group exhibited significantly shorter escape latency (P<0.05, P<0.01). The number of crossings over the original platform was significantly reduced in the model group compared with the sham-operated group (P<0.01), whereas rats in the DBT and donepezil groups showed significantly increased platform crossings compared with the model group (P<0.05, P<0.01). Compared with the sham-operated group, exploration time of new objects was significantly reduced in the model group (P<0.01). Compared with the model group, exploration time of new objects increased significantly in the medium- and high-dose DBT groups and the donepezil group (P<0.05, P<0.01), while no significant change was observed in the low-dose DBT group. Compared with the high-dose DBT group, rats in the donepezil group had significantly prolonged escape latency and reduced platform crossings and new-object exploration time (P<0.05). Nissl staining showed decreased density of healthy neurons in the CA1 and CA3 regions of the hippocampus in the model group, with loss of Nissl bodies and nuclear atrophy or disappearance. In the high-dose DBT group, neuronal density in CA1 and CA3 increased, with neurons arranged closely and displaying normal morphology. Immunofluorescence showed that compared with the sham-operated group, the hippocampal NeuN⁺ cell count in the VAD model group was significantly decreased(P<0.01), compared with the VAD model group, the hippocampal NeuN⁺ cell count in the high-dose DBT group was significantly increased(P<0.01). Compared with the sham-operated group, the expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins was significantly increased(P<0.01), while the expression of Bcl-2 was significantly decreased in the VAD model group(P<0.01). Compared with the VAD model group, the high-dose DBT group showed significantly decreased expression of PINK1, Parkin, LC3Ⅱ, and Bax proteins(P<0.01)and significantly upregulated Bcl-2 expression(P<0.01). The medium-dose DBT group exhibited significantly reduced expression of Parkin, LC3Ⅱ, and Bax proteins(P<0.05,P<0.01) and significantly increased Bcl-2 expression(P<0.01), while no statistically significant differences were observed in the low-dose DBT group. Transmission electron microscopy showed mitochondrial pyknosis, thickened cristae, increased electron density, and the presence of mitochondrial autophagy in the model group. In contrast, hippocampal neurons in the high-dose DBT group contained abundant mitochondria with intact morphology, clear cristae, and uniform matrix. Compared with the sham-operated group, total antioxidant capacity, SOD activity, and GSH levels were significantly decreased, while MDA levels were significantly increased in the model group (P<0.01). Compared with the model group, total antioxidant capacity and antioxidant levels (SOD, GSH) increased significantly, and MDA decreased significantly in the medium- and high-dose DBT groups (P<0.01), while no significant changes were observed in the low-dose DBT group. Compared with the sham-operated group, mRNA expression of p22phox and p47phox was significantly increased in the model group (P<0.01). Compared with the model group, expression of p22phox and p47phox was significantly decreased in the DBT groups (P<0.05, P<0.01). ConclusionDBT may exert neuroprotective effects by regulating PINK1/Parkin-mediated mitochondrial autophagy, thereby improving learning and memory abilities and treating VAD.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

MethodsA total of 70 patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome meeting the inclusion criteria were enrolled from Anhui Provincial Hospital of TCM from October 1, 2023, to October 1, 2024. Participants were divided into a control group and an observation group, with 35 cases in each group. The control group received conventional copper chelation therapy with sodium dimercaptopropanesulfonate (DMPS). On this basis, the observation group was additionally administered GDFMD orally. Each treatment course lasted eight days, for a total of four treatment courses. Efficacy evaluations were performed before treatment and after the second and fourth treatment courses, respectively. The clinical efficacy and safety of GDFMD in the treatment of WD-related liver fibrosis were assessed by comparing the changes in liver stiffness measurement (LSM), liver serological markers [alanine aminotransferase (ALT), aspartate aminotransferase (AST), type Ⅳ collagen (C-Ⅳ), laminin (LN), N-terminal propeptide of type Ⅲ procollagen (PⅢNP), and hyaluronic acid (HA)], fibrosis index based on 4 factors (FIB-4), AST to platelet ratio index (APRI), unified Wilson's disease rating scale part Ⅱ (UWDRS-Ⅱ), traditional Chinese medicine (TCM) syndrome score, 24-hour urinary copper, and safety indicators between the two groups before and after treatment. ResultsCompared with those before treatment, LSM levels decreased in both groups after two and four treatment courses (P<0.05). Compared with those after treatment, there was no statistically significant difference in the improvement of LSM levels in the observation group after two treatment courses, and the improvement of LSM levels in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, the levels of HA, LN, PⅢNP, and C-Ⅳ decreased in both groups after two and four treatment courses (P<0.05). Compared with those after treatment, there was no statistically significant difference in the improvement of the C-Ⅳ levels in the observation group after two treatment courses, and the levels of HA, LN, and PⅢNP were more obvious (P<0.05). After four treatment courses in the observation group, the levels of HA, LN, PⅢNP, and C-Ⅳ were improved more significantly (P<0.05). Compared with those before treatment, ALT and AST levels decreased in both groups after two and four treatment courses (P<0.05). Compared with the control group after treatment, there was no statistically significant difference in the improvement of ALT and AST levels in the observation group after two treatment courses, and the improvement of ALT and AST levels in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, APRI score and FIB-4 index level decreased in both groups after two and four treatment courses (P<0.05). Compared with those in control group after treatment, there was no statistically significant difference in the improvement of APRI score and FIB-4 index level in the observation group after two treatment courses, and the APRI score in the observation group was more obvious after four treatment courses (P<0.05), with no statistically significant improvement in the FIB-4 index difference. Compared with those before treatment, the levels of TCM syndrome scores decreased in both groups after two and four treatment courses (P<0.05). Compared with that of the control group after treatment, there was no statistically significant difference in the improvement of the level of TCM syndrome scores in the observation group after two treatment courses, and the improvement of the level of TCM syndrome scores in the observation group was more obvious after four treatment courses (P<0.05). Compared with those before treatment, the UWDRS-Ⅱ scores in both groups after two treatment courses were not improved obviously, and the UWDRS-Ⅱ scores in both groups decreased after four treatment courses (P<0.05). Compared with those of the control group after treatment, there was no statistically significant difference in the improvement of the UWDRS-Ⅱ scores in the observation group after two treatment courses, and the improvement of the UWDRS-Ⅱ scores in the observation group after four treatment courses was more obvious (P<0.05). Compared with those before treatment, the 24-h urine copper levels were significantly higher in both groups after two and four treatment courses (P<0.05). Compared with those in the control group after treatment, the 24-h urine copper levels in the observation group were significantly higher after two and four treatment courses (P<0.01). After two treatment courses, the 24-h urine copper level in the observation group showed a gradual decreasing trend, although it was higher than that before treatment. After four treatment courses, the control group had an improvement rate of 91.43%, an effective rate of 34.29%, and an apparent rate of 2.86%. The observation group had an improvement rate of 94.29%, an effective rate of 71.43%, and an apparent rate of 8.57%. The efficacy of the observation group was better than that of the control group (P<0.05). Conclusion① The efficacy of GDFMD combined with DMPS therapy in patients with WD-related liver fibrosis of liver-kidney deficiency and phlegm-blood stasis syndrome is significantly better than that of single DMPS therapy, and the advantages of the combined therapy are more obvious with the prolongation of the treatment cycle. ② GDFMD combined with the DMPS therapy program in the long-term application exhibits no obvious adverse reactions with good safety, which is worthy of clinical popularization and application.

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.

ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis (CAG) with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching, patients were divided into a training set (namely dev) and a validation set (namely vad) in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator (namely Lasso) regression algorithms. Subsequently, a model, named model 1se, was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods, including the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow test (H-L), calibration plot, and decision curve analysis (DCA). ResultsAge, body mass index (BMI), family history of cancer, job and life satisfaction, yellow and greasy fur with slippery pulse, and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration, which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.
