Chinese Journal of Experimental Traditional Medical Formulae 2026;32(5):21-31
ObjectiveThis study aimed to investigate the optimal compatibility ratio of the Chuanxiong Rhizoma-Carthami Flos (CR-CF) couplet medicines in ischemic stroke (IS) therapy and its pharmacological action mechanism, providing a scientific basis for the clinical application of CR-CF couplet medicines in IS therapy. MethodsThe chemical composition of CR-CF was analyzed using liquid chromatography mass spectrometry (LC-MS/MS). The contents of eight characteristic chemical components in aqueous extracts of CR-CF with common clinical compatibility ratios (1∶1, 1∶2, 1∶3, 3∶2, 2∶1) were determined by ultra-high performance liquid chromatography(UHPLC). An oxygen-glucose deprivation/reoxygenation (OGD/R)-induced mouse hippocampal neuron HT22 cell injury model was established, and cells were treated with different CR-CF compatibility ratios. The collaborative index (CI) was calculated by using CompuSyn software. A cerebral artery occlusion/reperfusion (MCAO/R) model of rats was induced by using the modified Longa suture method. The rats were divided into the sham group, model group, Chuanxiong Rhizoma (CR) group (1.3 g·kg-1), Carthami Flos (CF) group (3.9 g·kg-1), CR-CF group (5.2 g·kg-1), and edaravone group (5 mg·kg-1). Neuronal defect scores were assessed by the Longa scoring method. Cerebral infarction volume was measured by 2,3,5-triphenyltetrazolium chloride(TTC) staining. Neuronal damage was observed via hematoxylin-eosin (HE) staining. Neuronal apoptosis of rats was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining, and the expression of apoptosis-related proteins was analyzed by Western blot. Label-free proteomics was employed to screen differentially expressed proteins, and Western blot was used to examine the expression of phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway-related proteins. Finally, molecular docking was performed to predict the binding affinity of eight active constituents in CR-CF (1∶3) with PI3K. ResultsWhen CR-CF was combined at a 1∶3 ratio, the total content of the eight active constituents in the extract was the highest, and the synergistic protective effect on OGD/R-injured HT22 cells was the strongest (CI=0.308). Animal experiments showed that compared with the sham group, the model group exhibited increased neuroecological score points (P<0.01), larger cerebral infarction volumes (P<0.01), aggravated brain tissue damage, elevated neuronal apoptosis (P<0.01), and increased B-cell lymphoma-2(Bcl-2)-associated X protein (Bax)/Bcl-2 and cleaved Cysteinyl aspartate specific proteinase-3/Cysteinyl aspartate specific proteinase-3 (cleaved Caspase-3/Caspase-3) ratios (P<0.01). Compared with the model group, CR-CF (1∶3) significantly reduced neurological scores (P<0.01), significantly decreased cerebral infarction volume (P<0.01), alleviated brain tissue damage, inhibited neuronal apoptosis (P<0.01), and significantly lowered the Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 ratios (P<0.01). The therapeutic effect of CR-CF (1∶3) was superior to that of CR or CF alone. Proteomic analysis revealed that CR-CF (1∶3) activated the PI3K/Akt signaling pathway. Validation experiments demonstrated that compared with the sham group, the model group showed obviously reduced p-PI3K/PI3K and p-Akt/Akt (P<0.05). Compared with the model group, p-PI3K/PI3K and p-Akt/Akt ratios (P<0.05) obviously increased. Compared with the CR-CF group, the 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one LY294002 inhibitor+CR-CF group exhibited obviously decreased p-PI3K/PI3K and p-Akt/Akt (P<0.05). Molecular docking results indicated that the active constituents of CR-CF (1∶3) had strong binding affinity with PI3K. ConclusionThe CR-CF couplet medicines at a 1∶3 ratio exhibit optimal synergistic effects, and their anti-IS mechanism is closely related to activation of the PI3K/Akt signaling pathway and inhibition of neuronal apoptosis.

ObjectiveTo investigate the status of overlapping hepatitis B virus (HBV) infection in patients with chronic hepatitis C virus (HCV) infection and the serological characteristics of such patients. MethodsA total of 8 637 patients with HCV infection who were hospitalized from January 1, 2010 to December 31, 2020 and had complete data of HBV serological markers were enrolled, and the composition ratio of patients with overlapping HBV serological markers was analyzed among the patients with HCV infection. The patients were divided into groups based on age and year of birth, and serological characteristics were analyzed, and the distribution of HBV-related serological characteristics were analyzed across different HCV genotypes. ResultsThe patients with HCV/HBV overlapping infection accounted for 5.85%, and the patients with previous HBV infection accounted for 48.10%; the patients with protective immunity against HBV accounted for 14.67%, while the patients with a lack of protective immunity against HBV accounted for 31.39%. The patients were divided into groups based on age: in the 0 — 17 years group, the patients with protective immunity against HBV accounted for 61.41% (304 patients); the 18 — 44 years group was mainly composed of patients with previous HBV infection (698 patients, 37.31%), the 45 — 59 years group was predominantly composed of patients with previous HBV infection (1 945 patients, 50.38%), and the ≥60 years group was also predominantly composed of patients with previous HBV infection (1 486 patients, 61.66%). The patients were divided into groups based on the year of birth: in the pre-1992 group, the patients with previous HBV infection accounted for 51.63% (4 112 patients); in the 1992 — 2005 group, the patients with protective immunity against HBV accounted for 54.72% (168 patients); in the post-2005 group, the patients with protective immunity against HBV accounted for 64.38% (235 patients). In this study, 6 301 patients underwent HCV genotype testing: the patients with genotype 1b accounted for the highest proportion of 51.71% (3 258 patients), followed by those with genotype 2a (1 769 patients, 28.07%), genotype 3b (63 patients, 1.00%), genotype 3a (10 patients, 0.16%), genotype 4 (21 patients, 0.33%), and genotype 6a (5 patients, 0.08%). ConclusionWith the implementation of hepatitis B planned vaccination program in China, there has been a significant reduction in the proportion of patients with previous HBV infection among the patients with HCV/HBV overlapping infection, but there is still a relatively high proportion of patients with a lack of protective immunity against HBV.

ObjectiveTo observe the clinical efficacy of Shentong Zhuyutang combined with Dilongtang in the treatment of lumbar disc herniation (LDH) with Qi stagnation and blood stasis syndrome, and its effect on nucleus pulposus reabsorption and immune-inflammatory factors, exploring its therapeutic mechanism from the perspective of reabsorption. MethodsA total of 120 patients with LDH from the Fourth Clinical Medical College of Guangzhou University of Chinese Medicine, treated between June 2020 and January 2023, were randomly divided into the control group (52 cases, with 8 dropouts) and the observation group (49 cases, with 11 dropouts) according to a random number table. The control group received routine treatment, while the observation group was treated with Shentong Zhuyutang combined with Dilongtang in addition to routine treatment. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) score, and traditional Chinese medicine (TCM) syndrome score were measured before treatment and after 3 courses of treatment. Venous blood samples were collected for the determination of serological indexes. MR examination was performed during the 6-month follow-up to calculate the absorption rate. ResultsAfter treatment, both groups showed significant reductions in VAS, ODI, TCM syndrome score, serum tumor necrosis factor (TNF)-α, matrix metalloproteinase (MMP)-9, and vascular endothelial growth factor (VEGF) levels, and a significant increase in JOA score compared with pre-treatment values (P<0.05). Compared with the control group, the observation group showed significantly lower VAS, ODI, TCM syndrome score, serum TNF-α, MMP-9, and VEGF levels, and a significantly higher JOA score (P<0.05). The proportion of nucleus pulposus reabsorption in the observation group was 57.14% (28/49), significantly higher than 21.15% (11/52) in the control group (χ2=6.161, P<0.05). ConclusionShentong Zhuyutang combined with Dilongtang can effectively relieve pain, improve lumbar function, and alleviate TCM clinical symptoms in LDH patients with Qi stagnation and blood stasis syndrome. Imaging findings suggest that the treatment promotes the reabsorption of nucleus pulposus protrusion, while laboratory testing shows reduced serum levels of TNF-α, MMP-9, and VEGF, which contribute to the rehabilitation of patients.

Virus-related lymphoma exhibits a dual nature as both a hematologic malignancy and a viral infectious disease, making it more resistant to treatment and associated with poorer prognosis. This paper analyzes the understanding and therapeutic advantages of traditional Chinese medicine (TCM) in virus-related lymphoma. It proposes a TCM-based approach centered around syndrome differentiation, using standardized measurements of the overall TCM condition, multi-omics research of hematologic tumors, and artificial intelligence technologies to identify the "pre-condition" of virus-related lymphoma. A risk warning model will be established to early identify high-risk populations with viral infections that may develop into malignant lymphoma, thereby establishing a risk warning system for virus-related lymphoma. At the same time, a TCM health management approach will be applied to manage and regulate virus-related lymphoma, interrupting its progression and forming a human-centered, comprehensive, continuous health service model. Based on this, a standardized, integrated clinical prevention and treatment decision-making model for virus-related lymphoma, recognized by both Chinese and western medicine, will be established to provide TCM solutions for primary prevention of major malignant tumors.

OBJECTIVE To investigate the effects and mechanism of Wenpi tongluo kaiqiao formula (WPTL) against neuronal necroptosis in Alzheimer’s disease (AD) mice based on the Z-DNA binding protein 1 (ZBP1)/mixed lineage kinase domain-like protein (MLKL) signaling pathway. METHODS Forty APP/PS1 transgenic AD mice were randomly divided into model group, WPTL low-dose (WPTL-L) group (10.4 g/kg, calculated by the raw medicine), WPTL high-dose (WPTL-H) group (20.8 g/kg, calculated by the raw medicine) and donepezil hydrochloride group (3 mg/kg), with 10 mice in each group; another 10 C57BL/6J mice were selected as normal control group. Intragastric administration, once a day, for 30 consecutive days. Twenty-four hours after the last administration, Morris water maze test was performed to evaluate learning and memory abilities; the pathological morphology of hippocampal tissues was observed; the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) were determined; the expressions of amyloid precursor protein (APP), Tau protein, and ZBP1/MLKL signaling pathway-related proteins in hippocampal tissues were detected; the positive expression of phosphorylated receptor-interacting protein kinase 3 (p-RIPK3) in the neurons of hippocampal tissues and mRNA expression of ZBP1 were measured in hippocampal tissues. RESULTS Compared with normal control group, the escape latency of mice in model group was prolonged significantly on day 3 to 5 (P<0.05), the times of crossing platform reduced significantly (P<0.05), and obvious pathological changes were observed in the hippocampal tissue. The level of TNF- α, the expressions of APP, p-Tau and ZBP1, the phosphorylation levels of RIPK1, RIPK3 and MLKL, the fluorescence intensity of p-RIPK3 as well as the mRNA expression of ZBP1 were significantly increased (P<0.05), while the serum level of IL-4 was decreased significantly (P<0.05). Compared with model group, above indexes were reversed significantly in administration groups (P<0.05), and pathological damage of hippocampal tissue was alleviated. CONCLUSIONS WPTL can inhibit the ZBP1/MLKL signaling pathway, reduce neuronal necroptosis in AD mice, and inhibit inflammatory responses, thereby improving learning and spatial memory abilities in AD mice.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management (MTM) services for patients with coronary heart disease by using Economic, Clinical and Humanistic Outcomes (ECHO) model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 (pre-quality control implementation group, n=96) and June-August 2023 (post-quality control implementation group, n=164). Using propensity score matching analysis, 80 patients were selected from each group. The study subsequently compared the economic, clinical, and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching (P>0.05). Compared with pre-quality control implementation group, the daily treatment cost (16.26 yuan vs. 24.40 yuan, P<0.001), cost-effectiveness ratio [23.12 yuan/quality-adjusted life year (QALY) vs. 32.32 yuan/QALY, P<0.001], and the incidence of general adverse drug reactions (2.50% vs. 10.00%, P=0.049) of post-quality control implementation group were decreased significantly; the utility value of the EuroQol Five-Dimensional Questionnaire (0.74± 0.06 vs. 0.71±0.07, P=0.003), the reduction in the number of medication related problems (1.0 vs. 0.5, P<0.001), the medication adherence score ([ 6.32±0.48) points vs. (6.10±0.37) points, P=0.001], and the satisfaction score ([ 92.56±1.52) points vs. (91.95±1.56) points, P=0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups (1.25% vs. 3.75%, P=0.310). CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care, and the ECHO model can quantitatively evaluate the effect of MTM services, making pharmaceutical care better priced and more adaptable to social needs, thus being worthy of promotion.

ObjectiveTo explore the quantity-quality transfer process of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(Haliotis discus hannai) by analyzing the physical phase and compositional changes, so as to provide references for the effective control of its quality. MethodsA total of 20 batches of Haliotidis Concha(H. discus hannai) from different habitats were collected and prepared into corresponding calcined products and standard decoction, and the content of CaCO3 of the three samples were determined and the extract yield and transfer rate of CaCO3 were calculated. The changes in elemental composition and their relative contents were investigated by X-ray fluorescence spectrometry(XRF), X-ray diffraction(XRD) was used to study the changes in the phase compositions of the three samples and to establish their respective XRD specific chromatogram. Fourier transform infrared spectrometry(FTIR) was used to study the changes in the chemical composition and content changes of the three samples and to establish their respective FTIR specific chromatogram, while combining hierarchical cluster analysis(HCA), principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) to find the common and differential characteristics, in order to explore the quantity-quality transfer relationship in the preparation process of standard decoction of Haliotidis Concha(H. discus hannai). ResultsThe CaCO3 contents of the 20 batches of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(H. discus hannai) were 93.87%-98.95%, 96.02%-99.97% and 38.29%-51.96%, respectively, and the extract yield of standard decoction was 1.71%-2.37%, and the CaCO3 transfer rate of decoction pieces-standard decoction was 0.68%-1.27%. XRF results showed that the elemental species and their relative contents contained in Haliotidis Concha and its calcined products had a high degree of similarity, and although there was no obvious difference in the elemental species contained in decoction pieces and standard decoction, the difference in the relative contents was obvious, which was mainly reflected in the decrease of the relative content of element Ca and the increase of the relative content of element Na. XRD results showed that Haliotidis Concha mainly contained CaCO3 of aragonite and calcite, while calcined Haliotidis Concha only contained CaCO3 of calcite, and standard decoction mainly contained CaCO3 of calcite and Na2CO3 of natrite. FTIR results showed that there were internal vibrations of O-H, C-H, C=O, HCO3- and CO32- groups in Haliotidis Concha, while O-H, HCO3- and CO32- groups existed in the calcined products and standard decoction. ConclusionThe changes of Haliotidis Concha and calcined Haliotidis Concha are mainly the increase of CaCO3 content, the transformation of CaCO3 aragonite crystal form to calcite crystal form and the absence of organic components after calcination, and the changes of calcined products and standard decoction are mainly the decrease of CaCO3 content and the increase of Na2CO3 relative content. The method established in the study is applicable to the quality control of the shellfish medicines-decoction pieces- standard decoction, which provides a new idea for the study of quality control of dispensing granules of shellfish medicines.

Purpose:
Neuroendocrine prostate cancer (NEPC) represents a particularly aggressive subtype of prostate cancer with a challenging prognosis. The purpose of this investigation is to craft and confirm the reliability of nomograms that can accurately forecast the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS) rates for individuals afflicted with NEPC.
Materials and Methods:
Data pertaining to patients diagnosed with NEPC within the timeframe of 2010 to 2020 was meticulously gathered and examined from the Surveillance, Epidemiology, and End Results Program (SEER). To predict OS and CSS, we devised and authenticated two distinct nomograms, utilizing predictive variables pinpointed through both univariate and multivariate Cox regression analyses.
Results:
The study encompassed 393 of NEPC patients, who were systematically divided into training and validation cohorts at a 2:1 ratio. Key prognostic factors were isolated, verified, and integrated into the respective nomograms for OS and CSS. The performance metrics, denoted by C-indices, stood at 0.730, 0.735 for the training set, and 0.784, 0.756 for the validation set. The precision and clinical relevance of the nomograms were further corroborated by the analysis of receiver operating characteristic curves, calibration plots, and decision curve analyses.
Conclusions
The constructed nomograms have demonstrated impressive efficacy in forecasting the 1-, 3-, and 5-year OS and rates for patients with NEPC. Implementing these predictive tools in clinical settings is anticipated to considerably enhance the care and treatment planning for individuals diagnosed with this aggressive form of prostate cancer, thus providing tailored and more precise prognostic assessments.

Background:
and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking.
Methods:
This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance.
Results:
Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal.
Conclusions
The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.
