Post-stroke cognitive impairment （PSCI） is a common and severe complication in stroke patients， significantly affecting their quality of life and social function. Despite increasing research on PSCI in recent years， effective therapeutic methods remain limited. The Wnt/β-catenin signaling pathway has emerged as a critical research focus in neuroscience due to its essential role in neuroprotection， neurorepair， and cognitive recovery. Dysregulation of the Wnt/β-catenin pathway is considered one of the key mechanisms in the onset and progression of PSCI. Traditional Chinese medicine （TCM）， with its multi-component， multi-target， and synergistic properties， has shown unique advantages in modulating the Wnt/β-catenin signaling pathway， providing a potential novel approach for PSCI treatment. TCM regulates the Wnt/β-catenin pathway through various mechanisms and exerts effects such as inhibiting cell apoptosis， maintaining blood-brain barrier integrity， reducing neuroinflammation， promoting neuroplasticity， and enhancing neurorepair， thereby improving post-stroke cognitive function. This review summarized the latest research progress on the regulation of the Wnt/β-catenin signaling pathway by TCM in intervening PSCI. It analyzed the mechanisms of action of various TCM components and compound formulas within this pathway， aiming to provide a theoretical basis for innovative strategies for PSCI treatment in the future and offer new research insights and practical guidance for the application of TCM in cerebrovascular diseases.

ObjectiveTo investigate the effects of Astragali Radix polysaccharides （APS） on the polarization of BV2 microglial cells in an oxygen-glucose deprivation/reoxygenation （OGD/R） model through regulation of the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） signaling pathway. MethodsThe OGD/R injury model of BV2 microglia was established and divided into blank group， OGD/R group and APS group （0.4 g·L^-1 APS）. Neuroinflammatory injury was induced by lipopolysaccharide （LPS） and treated with APS. The cells were divided into blank group， LPS group （1 mg·L^-1 LPS） and APS group （0.4 g·L^-1 APS+1 mg·L^-1 LPS）. Cell viability was detected using the cell counting kit-8 （CCK-8） assay. Cell morphology was observed under an inverted microscope. Nitric oxide （NO） content in the cell supernatant was determined by the Griess assay. The secretion levels of tumor necrosis factor-α （TNF-α）， interleukin （IL）-6， IL-10， and IL-4 were measured by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence （IF） was used to detect the double-positive rates of ionized calcium-binding adapter molecule-1/inducible nitric oxide synthase （Iba-1⁺/iNOS⁺） and ionized calcium-binding adapter molecule-1/arginase 1 （Iba-1⁺/Arg1⁺）， as well as the nuclear translocation rate of nuclear factor-κB p65 （NF-κB p65）. Protein expression levels of Iba-1， iNOS， Arg1， TLR4， and NF-κB p65 were detected by Western blot. ResultsIn the OGD/R injury model， compared with the blank control group， BV2 microglial cells in the OGD/R group were activated and exhibited amoeboid morphological changes. The secretion levels of NO， TNF-α， and IL-6 were significantly increased （P<0.01）. The double-positive expression rate of Iba-1⁺/iNOS⁺ and the protein expression of Iba-1 and iNOS were significantly increased （P<0.01）. The nuclear translocation rate of NF-κB p65 and the protein expression levels of TLR4 and NF-κB p65 were significantly increased （P<0.01）. The levels of IL-10 and IL-4 were significantly decreased （P<0.01）， and the double-positive expression rate of Iba-1⁺/Arg1⁺ and Arg1 protein expression were significantly decreased （P<0.01）. Compared with the OGD/R group， the APS group （0.4 g·L^-1） showed reduced cell activation， significantly decreased secretion levels of NO， TNF-α， and IL-6 （P<0.01）， significantly decreased double-positive expression rate of Iba-1⁺/iNOS⁺ and relative protein expression of Iba-1 and iNOS （P<0.01）， significantly decreased nuclear translocation rate of NF-κB p65 and protein expression levels of TLR4 and NF-κB p65 （P<0.01）， significantly increased levels of IL-10 and IL-4 （P<0.01）， and significantly increased double-positive expression rate of Iba-1⁺/Arg1⁺ and Arg1 protein expression （P<0.01）. In the LPS-induced neuroinflammation model， compared with the blank control group， the LPS group showed increased cell activation， significantly increased levels of NO， TNF-α， and IL-6， significantly increased Iba-1⁺/iNOS⁺ double-positive expression rate， NF-κB p65 nuclear translocation rate， and protein expression levels of Iba-1， iNOS， TLR4， and NF-κB p65 （P<0.01）， while IL-10 and IL-4 levels， Iba-1⁺/Arg1⁺ double-positive expression rate， and Arg1 protein expression were significantly decreased （P<0.01）. Compared with the LPS group， the APS group showed reduced cell activation， significantly decreased levels of NO， TNF-α， and IL-6， Iba-1⁺/iNOS⁺ double-positive expression rate， NF-κB p65 nuclear translocation rate， and protein expression levels of Iba-1， iNOS， TLR4， and NF-κB p65 （P<0.01）， while IL-10 and IL-4 levels， Iba-1⁺/Arg1⁺ double-positive expression rate， and Arg1 protein expression were significantly increased （P<0.01）. ConclusionAPS may reduce microglial activation and promote their polarization toward the M2 phenotype by inhibiting activation of the TLR4/NF-κB signaling pathway， thereby alleviating the neuroinflammatory response induced by OGD/R.

This paper summarizes professor LI Guolie's clinical experience in treating orthostatic hypotension （OH） based on the theory of "raising the clear and directing the turbid downward". It is considered that the core pathogenesis of OH lies in the body's transition from a supine to an upright position， during which dysfunction of the middle jiao （焦） transformation and transportation， along with impaired pivot function， hinders the ascending of clear yang and the descending of turbid yin. Treatment should follow the general principle of "ascending the clear and directing the turbid downward"， placing emphasis on distinguishing the primary and secondary aspects. For cases where the clear yang fails to ascend， the self-formulated Li's Shengqing Jiangzhuo Decoction （李氏升清降浊汤）is used to supplement qi， raise the clear， and strengthen the middle jiao. For cases where the turbid yin fails to descend， the self-formulated Wuxiang Qingzhuo Beverage（五香清浊饮）with modifications is applied to resolve phlegm， eliminate stasis， harmonize the middle， and descend the turbid.

Objective To explore the communication preferences for advance care planning(ACP)among elderly hospitalized patients and to provide references for improving the ACP implementation rate.Methods Convenience sampling was used to select elderly hospitalized patients from a tertiary hospital in Wenzhou City between April and November 2023.Face-to-face surveys were conducted using a general data collection form and a self-designed questionnaire on ACP communication preferences.Mixed Logit Model,willingness-to-pay analysis,relative importance analysis,and subgroup analysis were employed to explore preferences.Results 204 questionnaires were distributed and 200 valid questionnaires were recovered,with a valid questionnaire response rate of 98.04％.The Mixed Logit Model analysis indicated that key attributes-communication timing,communication form,family participation in ACP communication,legal validity of ACP documents,and out-of-pocket costs-significantly influenced preferences(P＜0.05).Willingness-to-pay analysis showed that changes in communication timing,communication form,and family participation altered patients' willingness to pay.Relative importance analysis ranked the top 3 attributes as commu-nication timing,communication form,and family participation.Subgroup analysis revealed that gender,education level,and residence location affected preferences(P＜0.05).Conclusion Key attributes of ACP communication affect elderly hospitalized patients' preferences and willingness to pay,with variations across subgroups.Healthcare professionals should develop optimal communication programs based on patient preferences and individual characteristics.

BACKGROUND: Most studies have evaluated disability-adjusted life years (DALYs) of colorectal cancer (CRC) patients based on a set of generic disability weights (DWs). This study aimed to apply local CRC-stage-specific DWs to estimate the burden of DALYs for CRC (CRC-DALYs) in populations in China and consider the influence of local screening coverage of CRC. METHODS: A prevalence-based model was constructed using data from various sources. Years lived with disability (YLDs) were estimated mainly via cumulative prevalence data (based on CRC incidence rates, population numbers, and survival rates), stage-specific proportions of CRC, and DWs of the local population. Years of life lost (YLLs) were calculated based on the CRC mortality rates and standard life expectancies. CRC incidence and mortality rates for the years 2020, 2025, and 2030 were estimated by joinpoint regression, and the corresponding DALYs were predicted. The main assumption was made for CRC screening coverage. Sensitivity analyses were used to assess the impact of population, DWs, and coverage. RESULTS: In 2017, among the Chinese population, the estimated number of CRC-DALYs was 4,303,314 (11.9% for YLDs). If CRC screening coverage rate in China (2.3%) remains unchanged, the overall DALYs in 2030 are predicted to increase by 37.2% (45.1% of those aged ≥65 years). More optimistically, the DALYs would then decrease by 0.7% in 2030 (from 5,902,454 to 5,860,200) if the coverage could be increased to 25.0%. A sensitivity analysis revealed that using local DWs would change the base-case values by 5.7%. CONCLUSIONS The estimated CRC-DALYs in China using population-specific DWs were considerably lower (with a higher percentage of YLDs) than the global burden of disease (GBD) estimates (5,865,004, of 4.6% for YLDs), suggesting the impact extent of applying local parameters. Sustainable scale-up CRC screening needs to be in place to moderate the growth trend of CRC-DALYs in China.

Objective To investigate the achievement of early fluid resuscitation targets and factors influencing 28-day outcomes in patients with sepsis.Methods A retrospective cohort analysis was conducted.A total of 164 patients with sepsis admitted to the First Affiliated Hospital of Xinjiang Medical University between January 2022 and January 2024 were enrolled.Patients were divided into survival and death groups based on 28-day survival status,with both groups receiving early fluid resuscitation.Comparisons were made between groups for general characteristics[gender,age,body mass index(BMI),infection site,comorbidities],primary indicators[central venous pressure(CVP),mean arterial pressure(MAP),urine output],and secondary indicators[blood lactate acid(Lac),procalcitonin(PCT),heart rate,sequential organ failure assessment(SOFA)on intensive care unit(ICU)admission day,Glasgow coma scale(GCS),duration and dose of vasoactive medication use].Univariate analysis identified variables associated with prognosis,followed by multivariate Logistic regression to select independent risk factors.Receiver operator characteristic(ROC curve)were plotted to assess predictive performance of each risk factor for the 28-day prognosis of patients with sepsis.Results This study included 164 patients.The primary infection sites were mainly the lungs,abdominal cavity,and urinary system,accounting for 42.7%(70/164),38.4%(63/164),and 9.1%(15/164)respectively.The survival group comprised 141 patients,while the the death group included 23 patients.No statistically significant differences existed between groups in gender,BMI,infection site(soft tissue infection vs.others),underlying diseases,MAP,urine output(all P>0.05).Compared to the survival group,the death group showed significantly higher age,pulmonary infection rate,Lac levels,vasoactive drug duration/dose,heart rate,and SOFA scores,while the rates of abdominal,and urinary tract infection,as well as CVP,PCT,and GCS scores were significantly lower(all P<0.05).The achievement rates of early fluid resuscitation parameters:MAP target achievement was highest at 78.7%(129/164),followed by urine output compliance at 78.0%(128/164),while CVP compliance was the lowest at 39.0%(64/164).The overall compliance rate was 21.3%(35/164).Univariate analysis showed that age,pulmonary infection,Lac levels,duration and dose of vasoactive drugs,heart rate,PCT,GCS score,and SOFA score were all risk factors affecting the 28-day prognosis of patients with sepsis(all P<0.05).Multivariate Logistic regression analysis showed Lac levels,and pulmonary infection were independent risk factors affecting 28-day prognosis of patients with sepsis[odds ratio(OR)were 0.801,3.966,0.812,95%confidence interval(95%CI)were 0.711-0.903,1.149-13.696,0.674-0.979 respectively,P values were<0.001,0.029,0.029 respectively].ROC curve analysis demonstrated that age,Lac levels,and pulmonary infection all possessed predictive value for 28-day outcomes(all P<0.05).Age exhibited the highest predictive value with an AUC of 0.922.At the optimal cut-off of 76.6 years,sensitivity reached 95.7%and specificity 80.9%.Conclusion The overall achievement rate of early fluid resuscation in sepsis patients was low,with age,Lac levels,and pulmonary infection being major factors influencing poor prognosis.

Objectives:To investigate the physical growth status of pediatric patients with transfusion-dependent thalassemia (TDT) and analyze the effects of treatment-related and socioeconomic factors on physical growth.Methods:Based on the specialized thalassemia database from gene therapy clinical research at the Institute of Hematology & Hospital of Blood Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, we collected data on height and weight development, family economic status, and medical records of 338 pediatric patients with TDT from October 2023 to May 2024. The length/height-for-age and body mass index (BMI) -for-age were classified based on the Growth Standard for Children under 7 Years of Age, Standard for Height Level Classification among Children and Adolescents Aged 7-18 Years, and Dietary Guidelines for Chinese Residents. Logistic regression analysis was conducted to assess the effects of family economic status and disease-related treatment on length/height-for-age and BMI-for-age.Results:Among the 338 patients, 118 were children and 220 were adolescents (192 males and 146 females), with a median age of 12 years (range: 0.8-18) and a median diagnosis duration of 10.3 years (range: 0.5-17.9). Subtypes included α-thalassemia [21 cases (6.2%) ], β-thalassemia [288 cases (85.2%) ], and combined αβ-thalassemia[29 cases (8.6%) ]. The monthly household income of patients was concentrated in 3 000-5 000 yuan (39.9%) and 5 001-10 000 yuan (34.9%), whereas 67.2% of the families had monthly medical expenses of <3 000 yuan. Of the patients, 75.5% received their first transfusion before 1 year of age. The proportions of children and adolescents with pretransfusion hemoglobin (HGB) of ≤70 g/L were 4.2% and 6.4%, respectively. Adolescents demonstrated significantly higher rates of transfusion frequency of <4 weeks/session, monthly red blood cell infusion of >2 U, serum ferritin (SF) of ≥5 000 μg/L, iron chelation therapy, and splenectomy compared with children (all P<0.05). Of the 338 patients, 26.0%, 22.8%, and 8.9% demonstrated stunted growth, underweight, and concurrent stunted growth with underweight, respectively. No significant difference was observed in the stunted growth rates between children (22.9%) and adolescents (27.7%) ( P=0.402). However, the underweight rate in adolescents (26.8%) was significantly higher than that in children (15.3%) ( P=0.023). The multivariate analysis determined the following risk factors for stunted growth: monthly household income of <10 000 yuan (5 001-10 000 yuan: OR=5.49, 95% CI: 1.48-35.76; 3 000-5 000 yuan: OR=6.87, 95% CI: 1.88-44.60; <3 000 yuan: OR=9.29, 95% CI: 2.20-64.77), pretransfusion HGB of ≤70 g/L ( OR=3.25, 95% CI: 1.07-10.18), and SF of ≥5 000 μg/L ( OR = 3.04, 95% CI: 1.20-7.70). Longer diagnostic duration was associated with underweight ( OR=1.10, 95% CI: 1.01-1.20) . Conclusions:Children and adolescents with TDT with pretransfusion SF of ≥5 000 μg/L, HGB of ≤70 g/L, low monthly household income, or longer diagnosis duration were significantly more likely to experience delayed physical growth.

ObjectiveTo investigate the therapeutic effect and mechanism of modified Chunzetang on bladder fibrosis and detrusor function in rats with neurogenic bladder urinary retention induced by spinal cord injury. MethodsIn this study， an improved Hassan Shaker spinal cord transection method was used to establish a model of neurogenic bladder urinary retention induced by spinal cord injury， and rats with a spinal cord injury behavior score of 0 were selected for follow-up experiments. The selected rats were randomly divided into a model group （normal saline gavage）， low-dose traditional Chinese medicine （TCM） group （gavage of 14.4 g·kg^-1 modified Chunzetang）， high-dose TCM group （gavage of 28.8 g·kg^-1 modified Chunzetang）， positive drug group ［intraperitoneal injection of 0.05 g·kg^-1 nuclear transcription factor-κB （NF-κB） inhibitor pyrrolidine dithiocarbamate （PDTC）］， and combination group （intraperitoneal injection of 0.05 g·kg^-1 PDTC + gavage of 28.8 g·kg^-1 modified Chunzetang）. The rats in these groups were administrated with corresponding drugs once a day for four weeks. The BL-420s biofunction acquisition system was used in the experiment to calculate the urodynamic indexes， and the isolated bladder was quickly weighed. The detrusor traction experiment was used to record the minimum bladder contraction tension and frequency in each group. The pathological morphology and tissue fibrosis of detrusor in each group observed by Hematoxycin-eosin （HE） staining and Masson staining were compared. The expression level of α-smooth muscle actin （α-SMA） was detected by immunohistochemistry. Western blot was used to detect the protein expression of NF-κB p65， nuclear transcription factor-κB suppressor protein α （IκBα）， transforming growth factor-β₁ （TGF-β₁）， type Ⅰ collagen （ColⅠ）， and type Ⅲ collagen （ColⅢ） in bladder tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was used to detect the changes in serum levels of IL-6， IL-1β， and TNF-α. ResultsCompared with that in the sham operation group， the pressure at the urinary leakage point in the model group decreased （P<0.01）， and the bladder mass， bladder contractile tension， maximum bladder capacity， and bladder compliance increased （P<0.05，P<0.01）. HE staining showed that the arrangement of bladder epithelial cells was disordered， and the pathological manifestations such as mucosa and myometria neutrophil infiltration were obvious. The lamina propria structure was destroyed， and the muscle fiber arrangement was disordered. The interstitial widening and tissue edema were obvious. Masson staining showed that the bladder wall of the model group had more collagen fiber deposition， and the degree of detrusor fibrosis was more severe. The content of detrusor in the visual field was reduced. At the same time， the protein expressions of NF-κB p65， TGF-β₁， IκBα， ColⅠ， and ColⅢ in bladder tissue of rats in the model group were significantly increased （P<0.01）， and the serum levels of IL-6， IL-1β， and TNF-α were significantly increased （P<0.05）. Compared with that in the model group， the pressure at the urinary leakage point in the modified Chunzetang and positive drug groups was increased （P<0.05）， and the wet bladder weight， minimum bladder contractile tension， maximum bladder capacity， and bladder compliance were restored （P<0.05， P<0.01）. HE and Masson showed that the bladder epithelial cells were relatively neatly arranged， and the structure of the bladder lamina propria was relatively stable. The detrusor bundles were arranged in an orderly manner， and the interstitium was narrow. The degree of tissue edema was relatively low， and the degree of bladder detrusor fibrosis in the modified Chunzetang and positive drug groups was reduced， while the degree of bladder detrusor fibrosis in the positive drug group and combination groups was not obvious. The results of Western blot showed that the expression of NF-κB p65， IκBα， TGF-β₁， ColⅠ， and ColⅢ in bladder tissue， as well as the serum levels of IL-6， IL-1β， and TNF-α in modified Chunzetang and positive drug groups were significantly lower， and the expression of bladder tissue-related proteins and the serum levels of IL-6， IL-1β， and TNF-α in the TCM groups decreased significantly with the increase in dose （P<0.05）. The results of immunohistochemistry suggested that modified Chunzetang could fully affect the expression of α-SMA in bladder tissue. ConclusionModified Chunzetang can inhibit collagen deposition in bladder tissue of rats with urinary retention induced by spinal cord injury， delay the occurrence and development of bladder fibrosis， and protect the normal contractile function of bladder detrusor， and its mechanism may be related to inhibiting the NF-κB/TGF-β₁ signaling pathway， reducing the production of NF-κB p65， IκBα， TGF-β₁， ColⅠ， ColⅢ， and other related proteins， and protecting the muscle strength of detrusor.
