Stroke is the main cause of death and disability among adults in China and is characterized by high incidence， disability， mortality， and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang （DCQT） has a long history and proven efficacy in treating stroke. Clinically， DCQT is often used to treat stroke and its sequelae. However， the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research， the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage， reduce iron deposition， and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 （Nrf2）-mediated signaling pathway and p38 mitogen-activated protein kinase （MAPK） signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT， this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials， pharmacodynamic material basis， safety evaluation， and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT， 11 of which are currently confirmed absorbed components. Among them， emodin， rhein， chrysophanol， aloe-emodin， synephrine， hesperidin， naringin， magnolol， and honokiol can be used as quality markers （Q-markers） of DCQT. The mechanism of DCQT in treating stroke is complex， involving regulation of inflammatory responses， neuronal damage， oxidative stress， blood-brain barrier， brain-derived neurotrophic factor， and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Background:Ribosomal protein L22-like 1(RPL22L1)exerts regulatory effects on various malignant tumors such as lung cancer,prostate cancer,and cervical cancer.However,its role in colorectal cancer(CRC)remains unclear.Aims:To investigate the expression of RPL22L1 in CRC and its role in patients' prognosis and glucose metabolism of tumor cells.Methods:A total of 142 newly diagnosed CRC patients admitted to the Taizhou First People's Hospital from February 2022 to June 2024 were enrolled.The expression levels of RPL22L1 mRNA and protein were detected by quantitative real-time PCR and immunohistochemistry,respectively.The correlation between RPL22L1 expression and clinicopathological characteristics was analyzed.Kaplan-Meier survival analysis was used to evaluate the impact of RPL22L1 expression on the prognosis of CRC patients.RPL22L1 siRNA was transfected into SW480 cells to establish a low-expression cell model.Cell proliferation was assessed by CCK-8 assay,cell migration by Transwell chamber assay,and apoptosis by flow cytometry.Gene set enrichment analysis(GSEA)was performed to evaluate the effect of RPL22L1 on glucose metabolism of tumor cells.Results:The expression levels of RPL22L1 mRNA and protein were significantly higher in CRC tissues than in adjacent normal tissues(all P<0.05).The expression level of RPL22L1 mRNA was correlated with the TNM stage and carcinoembryonic antigen level of CRC(all P<0.05).Kaplan-Meier analysis showed that the cumulative survival rate of high RPL22L1 mRNA expression group was significantly lower than that of low-expression group(P=0.027).The expression level of RPL22L1 mRNA was significantly higher in SW480 cells than in normal intestinal epithelial cells(P<0.001).After inhibiting RPL22L1 expression,the proliferation and migration capacities of SW480 cells were significantly decreased(all P<0.05),the apoptosis rate was significantly increased(P=0.005),and the lactate level and relative glucose uptake level were significantly reduced(all P<0.05).GSEA indicated that RPL22L1 gene was associated with glycolysis/gluconeo-genesis(P=0.02).Conclusions:RPL22L1 is highly expressed in CRC and is associated with poor prognosis of patients,suggesting its potential as a molecular target for CRC therapy.Furthermore,RPL22L1 may promote the tumorigenesis and progression of CRC by modulating glucose metabolism.

Objective:To investigate the incidence and high-risk pathogenic factors of cardiovascular disease（CVD）in patients with rheumatic and autoimmune diseases，and to construct and validate a predictive model for the risk of CVD occurrence in these patients.Methods:A retrospective analysis was conducted on 239 patients with rheumatic and autoimmune diseases who underwent treatment and echocardiography at the Affiliated Hospital of Inner Mongolia Medical University between June 2020 and June 2023. General patient data，laboratory test results，and echocardiographic findings were collected. Follow-up was performed via electronic medical records or telephone surveys until December 2024 to determine the incidence of CVD，starting from the date of the first echocardiographic examination. Predictive factors were screened using univariate analysis and Lasso regression，and a Logistic regression model was constructed. Internal validation was performed using the Bootstrap method. The model's accuracy and clinical utility were assessed using the Hosmer-Lemeshow test，calibration curve，and decision curve analysis.Results:Among the 239 patients，111 developed CVD. Logistic regression analysis identified age，diastolic blood pressure，use of immunosuppressants，lymphocyte count（LYM），α-hydroxybutyrate dehydrogenase（α-HBDH）level，serum cystatin C（CysC），and right ventricular fractional area change（RVFAC）as independent predictive factors for CVD in these patients（all P<0.05）. The area under the ROC curve（AUC）for the prediction model was 0.895（95% CI = 0.856 - 0.935），and after Bootstrap validation，it was 0.894（95% CI = 0.861-0.925）. The Hosmer-Lemeshow test，calibration curve，and decision curve analysis all indicated that the model had good accuracy and clinical utility. Conclusions:Age，diastolic blood pressure，use of immunosuppressants，LYM，α-HBDH，CysC，and RVFAC may serve as independent risk factors for CVD in patients with rheumatic and autoimmune diseases. The prediction model based on echocardiography combined with laboratory indicators can，to some extent，predict the risk of CVD occurrence in these patients.

Objective To explore the mechanism of Wumei pill on ulcerative colitis(UC)in mice based on the anti oxidative stress pathway of nuclear factor erythroid 2-related factor 2(Nrf2)/antioxidant response element(ARE).Methods Seventy SPF male C57BL/6 mice were randomly divided into the control group,the UC group,the mesalazine group(MES group,0.82 g/kg MES),the low dose Wumei pill group(WMW-L group,5 g/kg crude drug),the middle dose Wumei pill group(WMW-M group,10 g/kg crude drug),the high dose Wumei pill group(WMW-H group,20 g/kg crude drug)and the high dose Wumei pills+Nrf2 inhibitor ML-385 group(WMW-H+ML-385 group,Wumei pills crude drug 20 g/kg+20 mg/kg ML-385),with 10 rats in each group.The disease activity index(DAI)score and colonic mucosa injury score were performed in mice after the last administration.Pathological changes of colonic mucosa in mice were observed by HE staining.The levels of interleukin(IL)-1β,tumor necrosis factor-α(TNF-α)and IL-6 in serum and colon tissue of mice were measured by enzyme-linked immunosorbent assay(ELISA).The content of malondialdehyde(MDA)in serum and colon tissue of mice was determined by thiobarbituric acid colorimetry(TBA).The activity of superoxide dismutase(SOD)in serum and colon tissue of mice was measured by xanthine oxidase method.The activity of glutathione peroxidase(GSH-px)in serum and colon tissue of mice was determined by direct method with dithiodinitrobenzoic acid(DTNB).The positive expression of Nrf2 in colon tissue of mice was observed by immunohistochemistry.The expression of heme oxygenase-1(HO-1)and NAD(P)H:quinone oxidoreductase-1(NQO1)proteins in colon tissue of mice were detected by Western blot assay.Results Compared with the control group,the DAI score,colonic mucosa injury score,colonic histopathology score,levels of IL-1β,TNF-α,IL-6 and MDA in serum and colonic tissue,and expression levels of Nrf2,HO-1 and NQO1 protein in colonic tissue of mice were increased in the UC group,levels of SOD and GSH-px in serum and colon tissue decreased(P＜0.05),the colon mucosa of mice was seriously damaged.Compared with the UC group,changes of corresponding indexes were contrary to the above in the MES group,the WMW-M group and the WMW-H group.However,the expression levels of Nrf2,HO-1 and NQO1 proteins in colon tissue were increased(P＜0.05),and the damage of colon mucosa in mice was alleviated.Changes of the above indexes were dose-dependent in the WMW-L group,the WMW-M group and the WMW-H group.There were no significant differences in the above indexes between the WMW-H group and the MES group.ML-385 attenuated the improvement effect of high dose Wumei pill on colon mucosa injury.Conclusion Wumei pill may alleviate the colon mucosal damage of UC mice by activating Nrf2/ARE antioxidant stress pathway.

Chronic aortic stenosis and regurgitation can cause left ventricular remodeling.Whether these changes are reversible and their reversibility after valve replacement are the main determinants affecting the timing and prognosis of surgery.Imaging techniques are commonly used to evaluate myocardial structure and function,in which echocardiography and enhanced CT are helpful to evaluate artificial flap function and monitor left ventricular deformation,while cardiac MR and PET/CT are helpful to identify the progression and regression of postoperative cardiac fibrosis.The combined application of these new techniques can improve clinical outcomes by early diagnosis and non-invasive detection of postoperative left ventricular reverse remodeling.This paper reviews the evaluation and application of multi-modal imaging techniques for left ventricular reverse remodeling after aortic valve replacement.
