Objective To investigate the effects of Duzhi Pills combined with MOTOmed training on limb function and activities of daily living in patients with cerebral infarction of qi deficiency and blood stasis type.Methods A prospective randomized controlled trial enrolled 98 cerebral infarction patients with qi deficiency and blood stasis treated at Qinhuangdao Hospital,Oriental Hospital of Beijing University of Chinese Medicine(Qinhuangdao Hospital of Traditional Chinese Medicine)from June 2022 to December 2024.Participants were randomized into control group(n=49,receiving conventional rehabilitation)and observation group(n=49,receiving additional Duzhi Pills+MOTOmed training)for 8 weeks.All patients received standard medication.Limb motor function and activities of daily living,and quality of life were assessed before and after treatment.Results(1)After treatment,both groups showed significant increases in Carroll Hand Function Test for Upper Extremity(CHFT-UE)scores,Fugl-Meyer Assessment Scale for Upper Extremity(FMA-UE)scores,and Simple Test for Evaluating Hand Function(STEF)scores compared to baseline(P＜0.05),with significantly greater improvements observed in the observation group(P＜0.01).(2)After treatment,both groups exhibited significant increases in Barthel Index scores for daily activity(P＜0.05),with the observation group demonstrating significantly greater improvement(P＜0.01).(3)After treatment,all subscale scores of the 36-Item Short-Form Health Survey(SF-36),including physical function,bodily pain,mental health,vitality,social functioning,emotional role,and general health,were significantly increased in both groups(P＜0.05),with significantly greater improvements in the observation group,the difference being statistically significant(P＜0.01).Conclusion The combined regimen of Duzhi Pills and MOTOmed training significantly enhances limb function,daily activity,and quality of life in cerebral infarction patients with qi deficiency and blood stasis syndrome,demonstrating clinical value for rehabilitation.

OBJECTIVE To investigate the effects of clopidogrel on the pharmacokinetics and pharmacodynamics of ciprofol in rats.METHODS Eighteen male SD rats were randomly divided into control group,clopidogrel normal-dose group and clopidogrel high-dose group,with 6 rats in each group.Among them,rats in the normal-dose group and high-dose group were given 7.5 mg/kg and 15 mg/kg clopidogrel by gavage,respectively,and rats in the control group were given the same volume of 0.5％sodium carboxymethyl cellulose solution,once a day,for 14 consecutive days.Afterward,2.4 mg/kg ciprofol was injected by tailvein and blood samples were collected from the inner canthus of the eye at 2,4,8,12,16,20,30,45 and 60 min after the end of the administration.During this period,the duration of the loss of righting reflex(LORR)in rats was counted.After the proteins were precipitated by acetonitrile,the rat plasma sample was analyzed by LC-MS/MS using deuterated ciprofol as the internal standard,Symmetry C18 as the chromatographic column,and acetonitrile-0.01％ammonia solution containing 5 mmol/L ammonium acetate(gradient elution)as the mobile phase to detect the concentration of ciprofol in the plasma.The pharmacokinetic parameters in rats were calculated by using DAS 2.0 software.RESULTS Compared with control group,area under the drug concentration-time curve and mean residence time of ciprofol increased or prolonged significantly,while plasma clearance decreased significantly in clopidogrel normal-dose and high-dose groups;the duration of LORR in rats was prolonged by 19.5％and 23.9％,with statistical difference(P＜0.05).However,there was no statistically significant difference in the pharmacokinetic parameters or LORR duration of ciprofol between the different dose groups of clopidogrel(P＞0.05).CONCLUSIONS Clopidogrel could inhibit the metabolism of ciprofol in rats and prolong the duration of LORR.

Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective:To compare the efficacy and safety of azacitidine combined with venetoclax or CAG regimen in the treatment of newly treated elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 34 newly treated elderly patients with AML treated in the Fifth People's Hospital of Datong from May 2018 to August 2023 were retrospectively analyzed. According to the treatment regimen, all patients were divided into venetoclax group (azacitidine + venetoclax, 17 cases) and CAG group (azacitidine + CAG regimen, 17 cases). The clinicopathological characteristics, efficacy, adverse reactions and survival of the both groups were compared.Results:There were no statistically significant differences in the clinical data of both groups (all P > 0.05). The complete remission (CR) rate and the objective response rate (ORR) in venetoclax group were higher than those in CAG group [CR: 70.6%(12/17) vs. 47.1% (8/17); ORR: 82.4% (14/17) vs. 64.7% (11/17)],while the differences in CR and ORR were not statistically significant (χ 2 = 2.00, P = 0.163; χ 2 = 2.00, P = 0.244). The follow-up time[ M ( Q1, Q3)] was 25.4 months (7.2 months, 60.3 months). At the end of follow-up, 19 of 34 patients survived (13 cases in venetoclax group and 6 cases in CAG group); 15 died (4 cases in venetoclax group and 11 cases in CAG group). The median overall survival (OS) time was 14.22 months (95% CI: 8.2-60.3 months) and 10.56 months (95% CI: 7.2-50.2 months), respectively in venetoclax group and CAG group;the median progression-free survival (PFS) time was 9.97 months (95% CI: 5.4-40.5 months) and 6.82 months (95% CI: 5.0-36.2 months), respectively, and there were no statistically significant differences in OS and PFS between the two groups (all P > 0.05). Grade 3-4 hematological adverse reactions occurred in 16 and 14 patients in venetoclax group and CAG group, respectively. There were no significant differences in granulocyte deficiency time, platelet deficiency time, infection and bleeding incidence between the two groups (all P > 0.05). Conclusions:Azacitidine combined with venetoclax or CAG regimen have better clinical efficacy and safety for newly treated elderly patients with AML.

Multidrug resistance (MDR) is the main factor of tumor recurrence and chemotherapy failure in clinical practice. Its mechanism is relatively complex, and one of the most thoroughly studied mechanism is the overexpression of P-glycoprotein (P-gp) on tumor cell membrane. Most of the chemotherapy drugs are p-gp substrates, and tumor cells will transport the chemotherapy drugs to the extracellular through p-gp mediated active transport, so that the concentration of effective drugs in the cell is reduced, resulting in drug resistance, leading to the decline of clinical efficacy. The reversal agent of P-gp can reduce the intracellular pumping of chemotherapeutic drugs by regulating the expression and transport activity of P-gp, and enhance the sensitivity of tumor cells to chemotherapeutic drugs, thus improving the therapeutic effect. In this paper, we will summarize the natural plant active ingredients that can reverse P-gp mediated MDR to provide reference for clinical and related studies.

Objective:To establish a model C-GALAD for detecting hepatocellular carcinoma (HCC) from the chronic liver disease and healthy people based on the serum markers.Methods:A clinical cohort including 229 hepatocellular carcinoma patients, 2 317 patients with chronic liver disease and 982 healthy people, was retrospectively collected from eight hospitals or physical examination institutions from April 2018 to October 2020. The data were divided into a training set and a testing set by stratified sampling with a 6∶4 ratio. A predictive model was established on the training set using a logistic backward regression method and validated on the testing set. In addition, clinical data from March to July 2021 in Beijing You′ an Hospital affiliated to Capital Medical University, including 84 patients with liver cancer and 204 patients with chronic liver disease collected were used for external independent validation of the model. The receiver operating characteristic curve (ROC) area under curve (AUC), the sensitivity and the specificity were used to evaluate the effectiveness of the model.Results:Through the logistic backward regression method, the seven signatures including age, gender, alpha-fetoprotein (AFP), alpha-fetoprotein alloplasm-3 ratio (AFP-L3%), des-gamma-carboxyprothrombin(DCP), platelet (PLT) and total bilirubin (TBIL) were selected as risk factors in the detection model. The area under the ROC curve (AUC) of the model on the testing set was 0.954, with an 88.04% sensitivity and a 94.85% specificity, and the AUC of model on the external independent validation set was 0.943, with an 89.29% sensitivity and a 90.2% specificity, which were better than other published models.Conclusion:The C-GALAD Ⅱ model can accurately predict the risk of hepatocellular carcinoma occurrence, and thus provide a trustworthy diagnosis method of hepatocellular carcinoma.

Although the tumor suppressor P53 is known to regulate a broad network of signaling pathways, it is still unclear how certain drugs influence these P53 signaling networks. Here, we used a comprehensive single-cell multiomics view of the effects of ginsenosides on cancer cells. Transcriptome and proteome profiling revealed that the antitumor activity of ginsenosides is closely associated with P53 protein. A miRNA-proteome interaction network revealed that P53 controlled the transcription of at least 38 proteins, and proteome-metabolome profiling analysis revealed that P53 regulated proteins involved in nucleotide metabolism, amino acid metabolism and "Warburg effect". The results of integrative multiomics analysis revealed P53 protein as a potential key target that influences the anti-tumor activity of ginsenosides. Furthermore, by applying affinity mass spectrometry (MS) screening and surface plasmon resonance fragment library screening, we confirmed that 20()-protopanaxatriol directly targeted adjacent regions of the P53 DNA-binding pocket and promoted the stability of P53-DNA interactions, which further induced a series of omics changes.
