This study aimed to investigate the mechanism of liquiritin (LQ) in the improvement of ventricular remodeling (VR) after acute myocardial infarction (AMI). Molecular docking was used to predict the binding affinity of liquiritin to thioredoxin-interacting protein (TXNIP). After 2 weeks of modeling, the rats were randomly divided into a model group, a low-dose liquiritin group (20 mg/kg LQ), and a high-dose liquiritin group (40 mg/kg LQ). Liquiritin was administered by gavage once a day, and the sham group and model group were given the same volume of 0.5% sodium carboxymethylcellulose (CMC-Na), with intervention of 4 consecutive weeks. Echocardiography was employed to detect the cardiac function, HE staining was used to observe cardiological changes, ELISA was used to detect the activity of serum creatine kinase-MB (CK-MB) activity, and the colorimetric method was adopted to detect serum malondialdehyde (MDA), total superoxide dismutase (T-SOD) and catalase (CAT) activities. RT-qPCR was used to detect the gene expressions of TXNIP, thioredoxin (TRX) and NACHT, LRR, and PYD domains-containing protein 3(NLRP3). Western blot was used to detect the protein expressions of TXNIP, TRX and NLRP3 in rat myocardial tissue. Molecular docking results showed that liquiritin had a good binding affinity to TNXIP target. After 20 and 40 mg/kg liquiritin intervention, the levels of ejection fraction (EF) and fractional shortening (FS) were significantly increased (P<0.01), and the levels of LVIDs, LVIDd, LVESV, and LVEDV were decreased (P<0.01). The myocardial structure was significantly improved, the cell arrangement tended to be regular, and the area of inflammatory cell infiltration and necrosis was reduced. Liquiritin significantly reduced the level of CK-MB (P<0.01), decreased the activity of MDA, and increased the activities of CAT and T-SOD (P<0.01). Liquiritin effectively inhibited the overexpression of TXNIP and NLRP3 genes and proteins, and enhanced the expression of TRX genes and proteins in the myocardial tissues of AMI rats. In conclusion, liquiritin has a regulatory effect on the TXNIP/TRX signaling pathway, inhibits the activation of the NLRP3 inflammasome, and thus improves ventricular remodeling after acute myocardial infarction.

The phrase"wood element characterized by spreading harmony"from the Huangdi Neijing five-phase theory summarizes the fundamental nature and functions of the wood element,emphasizing the crucial significance of the harmonious virtue of wood in promoting the generation and transformation of all things.In human physiology,"wood element characterized by spreading harmony"corresponds to the harmonious spreading of liver-gallbladder qi,ensuring smooth liver qi regulation and proper functioning of the ascending-descending movement mechanisms.Bipolar disorder,categorized in traditional Chinese medicine as"depression"or"manic depressive psychosis,"primarily arises from hepatic wood dysfunction.Insufficient wood qi dispersion typically manifests as a depressive phase,whereas excessive dispersion leads to a manic phase,with alternating manic-depressive phase indicating qi movement disorder.By integrating wood qi characteristics,disease pathogenesis of bipolar disorder,and our team's clinical experience in treating emotional disorders,this study developed an integrated acupuncture and moxibustion diagnosis and treatment approach for bipolar disorder,focusing on soothing the liver and regulating spirit,structured as"acupuncture-moxibustion-consolidation."Based on the physiological characteristics of"wood element characterized by spreading harmony,"from liver failing to controll conveyance and dispersion:depressive phase should apply warm-nourishing growth method,manic phase should suppress hyperactive liver for tranquillizing mind method,and alternating manic-depressive phase should apply harmonized rigidity-flexibility method.These methods aim to regulate the spirit of the heart and brain,harmonize the qi movement of the spleen and stomach,and replenish the essence and blood of the liver and kidney.Clinical application through syndrome differentiation has demonstrated satisfactory therapeutic outcomes.

Depression is closely associated with a neuro-endocrine-immune(NEI)system imbalance.The"excessive vitality leading to restraint and counter-regulation(Kang Hai Cheng Zhi)"theory elucidates the self-regulating mechanism for maintaining dynamic equilibrium in the body,and serves as an importance principle guiding treatment formulation and medication selection.Based on the correlation between NEI system imbalance and the traditional Chinese medicine pathogenesis of depression,and integrating the"Kang Hai Cheng Zhi"theory,the author posits that the pathogenesis of depression lies in overactive liver invading spleen,earth dampness impeding wood′s ascendancy,and disharmony between body and mind,as well as imbalance in storage and discharge functions of liver and kidney,disharmony between Yin and Yang,and disrupted counter-regulation.This dosely aligns with two key pathological methanisms at the micro level:microglial-limbic system homeostatic imbalance and hypothalamic-pituitary-adrenal axis-inflammatory circuit dysregulation.Clinically,the treatment principle for depression adheres to supporting the counter-regulation to restrain excess,with herbal interventions using strategies such as restraining wood to support earth,dredging earth to unblock wood,and harmonizing pivotal functions,as well as nourishing water to nurture wood,warming kidney to tonify liver,and relieving depression to calm the spirit.These approaches aim to regulate the liver,spleen,and kidney,embodying the core therapeutic tenet of"striving for equilibrium,"thereby restoring the body′s self-regulating capability.

Objective To investigate the effects of Yishen Zhuyu Tongluo Decoction on chondrocyte pyroptosis and ferroptosis in rats with knee osteoarthritis(KOA).Methods Forty SD were divided randomly into a sham operation group(n=10)and a modeling group(n=30).A KOA model was established in the modeling group by anterior cruciate ligament transection of the right hind limb knee joint.The drawer test was used to confirm the successful establishment of the model.Post-surgery,the rats were subjected to 30 min of forced activity daily to induce KOA.Lameness and hopping movements were observed after 4 weeks,and hematoxylin and eosin staining confirmed cartilage surface damage,deformation,and inflammatory cell infiltration,indicating successful modeling.The model rats were then assigned randomly to a model group(n=8),celecoxib group(n=8),and Yishen Zhuyu Tongluo Decoction group(n=8).The sham operation and model groups received 10 mL/kg of saline by gavage,the celecoxib group received 12 mg/kg of celecoxib solution,and the Yishen Zhuyu Tongluo Decoction group received 5.4 g/kg of the herbal decoction,once daily for 8 weeks.After the interventions,the rats were anesthetized,blood was collected from the abdominal aorta and serum was separated,and the knee joints were isolated.Three samples were fixed in paraformaldehyde,while the remaining cartilage tissue was reserved.Pathological changes in joint cartilage were observed by hematoxylin and eosin and Safranin O-Fast Green staining.Bone microstructure was analyzed using micro-computed tomography.Serum interleukin(IL)-1β and IL-18 protein levels were detected by enzyme-linked immunosorbent assay.Relative mRNA expression levels of NLRP3,ASC,Caspase-1,GSDMD,IL-1β,IL-18,ACSL-4,FTH-1,GPX-4,and cyclooxygenase(COX)-2 were detected by reverse transcription quantitative real-time PCR,and protein expression of NLRP3,Caspase-1,and COX-2 were detected by immunohistochemistry.Results Compared with the sham operation group,model rats showed surface damage and deformation of cartilage tissue,disordered cell arrangement in all layers,significant loss of Safranin O-Fast Green staining,and sparse and irregular trabecular bone distribution.Serum levels of the inflammatory factors IL-1β and IL-18 were elevated(P＜0.01).mRNA expression levels of NLRP3,ASC,Caspase-1,GSDMD,IL-1β,IL-18,ACSL-4,and COX-2 were also significantly increased(all P＜0.01),while FTH-1 and GPX-4 mRNA expression levels were decreased(P＜0.01).Compared with the model group,rats in the celecoxib and Yishen Zhuyu Tongluo Decoction groups showed smoother and more intact cartilage surfaces,significantly increased cell counts,less loss of Safranin O-Fast Green staining,denser trabecular bone,and thicker cortical bone,with improved bone microstructure.Serum IL-1β and IL-18 levels were reduced(P＜0.01),NLRP3(P＜0.01,P＜0.05),ASC,Capase-1,GSDMD,IL-1β,IL-18,ACSL-4,and COX-2 mRNA levels were decreased(all P＜0.01),and relative expression levels of FTH-1 and GPX-4 mRNA were significantly increased(P＜0.01).Conclusions Yishen Zhuyu Tongluo Decoction can treat KOA by inhibiting chondroptosis and ferroptosis in chondrocytes,reducing serum IL-1β and IL-18 levels,and improving bone microstructure.

Objective To analyze ancient prescriptions for knee osteoarthritis(KOA),and explore their application patterns,for providing clinical reference value.Methods Prescriptions were collected from ancient documents,and a database was created by using Excel 2016 for frequency analysis.Association rules and hidden structures were analyzed by using SPSS Modeler 18.0 and Lantern 5.0.Results A total of 373 prescriptions and 421 herbs were collected,with 3894 times of frequency of medication.Danggui was the most frequently used herb.Herbs primarily tonified deficiencies,relieved exterior symptoms,and expelled wind-dampness,with warm properties and pungent,sweet,or bitter tastes,mainly targeting the spleen and kidney meridians.Thirteen strong association rules were identified,including Chuanxiong+Niuxi-Danggui,and Bixie-Niuxi.Hidden structure analysis revealed 10 variables,leading to 4 clusters and 4 core prescriptions.Common syndromes included wind-damp,wind-cold-damp,wind-damp-heat,and qi-blood deficiency.Conclusion The treatment of KOA in ancient literature focuses on dispelling wind and removing dampness,taking into account both positive deficiency and evil excess,flexible use of tonifying spleen and kidney,clearing dampness-heat,tonifying Qi and blood and other drugs.

Objective:To analyze and validate the reliability and validity of the social skills improvement system-rating scales Chinese version (parent version) (SSIS-RS-C) in middle school students.Method:A total of 1 486 parents of middle school students were recruited according to the cluster sampling method.The social responsiveness scale and strengths and difficulties questionnaire were used as criterion validity tools.A retest was conducted one month later.SPSS 27.0 was used for descriptive statistics, item analysis, internal consistency test, test-retest reliability test and criterion validity test. AMOS 24.0 was used to perform confirmatory factor analysis .Results:Item analysis indicated significant positive correlations between each item and the subscales ( r=0.293-0.782, all P<0.01), with significant differences in scores between high and low groups ( t=10.079-37.038, all P<0.01).Confirmatory factor analysis supported a seven-factor structure for the social skills subscale(communication, cooperation, assertion, responsibility, empathy, engagement and self control) and a five-factor structure for the problem behavior subscale (externalizing, bullying, hyperactivity/inattention, internalizing and autism spectrum) of the SSIS-RS-C.There was a positive correlation between the social skills subscale and prosocial behavior ( r=0.637, P<0.001), and between the problem behavior subscale and social impairments and difficult behaviors ( r=0.765, 0.688, both P<0.001).The Cronbach's α coefficients for the total scale, social skills subscale and problem behavior subscale were 0.934, 0.972 and 0.963, respectively.The test-retest correlation coefficients for the total score and the two subscales were 0.665, 0.871 and 0.598, respectively (all P<0.001). Conclusion:The SSIS-RS-C demonstrated good reliability and validity in the Chinese adolescent population.

Objective To explore the value of combining apparent diffusion coefficient(ADC)heterogeneity with morphological indicators in assessing the pathological grading of non-muscle invasive bladder cancer(NMIBC).Methods The MRI images of 86 patients confirmed with NMIBC by surgical pathology were analyzed retrospectively.All patients underwent T2WI,diffusion weighted ima-ging(DWI),and dynamic contrast enhancement(DCE)examinations.Two radiologists independently measured tumor largest diam-eter(LD),actual tumor-wall contact length(ACTCL),ADCmean,ADCmin,and ADCmax values.ADC heterogeneity was calculated using the formula(ADCmax-ADCmin)/ADCmean.Differences in quantitative parameters between low-and high-grade NMIBC were compared using the Mann-Whitney U test,while differences in qualitative parameters were compared using the chi-square test.Univariate and multivariate logistic regression analyses were used to identify independent predictors of high-grade NMIBC,and receiver operating characteristic(ROC)curves were drawn to evaluate the performance of ADC heterogeneity combined with morphological indicators in assessing high-grade NMIBC.Results ADC heterogeneity and ACTCL were independent predictors for preoperative assessment of NMIBC pathological grading.The area under the curve(AUC)of ADC heterogeneity and ACTCL in assessing high-grade NMIBC were 0.843 and 0.744,respectively.The combined AUC was 0.902.The difference was statistically significant(P<0.05).Conclusion The combination of ADC heterogeneity with ACTCL can effectively improve the efficiency of preoperative assessment of NMIBC pathological grading,and providing more precise clinical decision-making and prognosis monitoring.

OBJECTIVE To investigate the time-effect relationship of ginger-partitioned moxibustion in treating fecal inconti-nence in patients with mild to moderate active Crohn's disease so as to optimize moxibustion duration and provide a basis for clinical application.METHODS A total of 128 patients with Crohn's disease complicated by fecal incontinence who met the inclusion crite-ria were selected as the study subjects.They were divided into a control group and three experimental groups(experimental group Ⅰ,Ⅱ,and Ⅲ)of 32 patients each using a stratified random method(with 1 dropout in experimental group Ⅰ).Patients in the control group received routine anti-tumor necrosis factor-α monoclonal antibody(adalimumab)treatment,while patients in the experimental groups received ginger moxibustion therapy in addition to the treatment provided to the control group.Among them,experimental groupⅠ received treatment for 20 minutes,experimental group Ⅱ for 40 minutes,and experimental group Ⅲ for 60 minutes.The course of treatment for all four groups was 3 months.Changes in TCM syndrome scores were compared before and after treatment in the four groups to assess clinical efficacy.The cleveland clinic incontinence score(CCIS)was used to assess the severity of fecal incontinence,the Crohn's disease activity index(CDAI)was used to assess the degree of disease activity,and the inflammatory bowel disease ques-tionnaire(IBDQ)was used to evaluate the quality of life.Anal pressure index and peripheral blood CRP and ESR levels were mea-sured,and the relationship between moxibustion time and effect was analyzed.RESULTS After 3 months of treatment,the total TCM syndrome scores of all four groups improved to varying degrees(P<0.05,P<0.01).The total scores of groups Ⅰ,Ⅱ,and Ⅲ were supe-rior to those of the control group(P<0.05,P<0.01),while group Ⅱ had the lowest total TCM syndrome score.Group Ⅱ had the high-est overall clinical effective rate,significantly better than both the control and group Ⅰ(P<0.05,P<0.01).CCIS scores,IBDQ scores and total scores,and peripheral blood ESR levels were significantly reduced in all four groups(P<0.01),with group Ⅱ having the low-est score,lower than both the control and group Ⅰ(P<0.05,P<0.01).CRP levels were significantly reduced in groups Ⅱ and Ⅲ(P<0.05,P<0.01),both lower than the control group(P<0.05,P<0.01),with group Ⅱ lower than group Ⅰ(P<0.01).Intestinal symptom scores in the IBDQ of groups Ⅱ and Ⅲ were significantly higher than those in the control group and group Ⅰ(P<0.05,P<0.01).The maximum resting pressure of the anal canal,rectal defecation threshold,and maximum tolerance capacity all increased significantly in the four groups(P<0.05,P<0.01),but there were no significant differences among the groups(P>0.05).During the treatment,two cases of mild skin redness occurred in group Ⅲ,which resolved after treatment,with no serious adverse reactions.CONCLUSION Ginger moxibustion in the treatment of Crohn's disease complicated by fecal incontinence exhibits a time-effect relationship,with 40 minutes as the optimal duration.It can effectively improve symptoms,control inflammation,enhance quality of life,and has good safety.

Objective To investigate the effects of microRNA-34a(miR-34a-5p)on the progression of chronic lymphocytic leukemia(CLL)through the Wnt/β-catenin signaling pathway.Methods Human chronic B-cell leukemia MEC-1 cells were selected for experimentation.MEC cells were divided into two groups,group one:the p53 agonist group and the control group;group two:the control group,the miR-34a-5p mimic group and its corresponding negative control,the miR-34a-5p inhibitor group and its corresponding negative control,as well as the miR-34a-5p inhibitor+Wnt inhibitor XAV-939 group.The expression levels of miR-34a-5p in each group were measured using real-time fluorescence quantitative PCR(qPCR).Cell proliferation was assessed by CCK-8 assay,while cell migration ability was evaluated using Transwell migration assay.Dual-luciferase reporter assay was employed to validate the targeting relationships between p53 and miR-34a-5p,as well as between miR-34a-5p and Wnt1.Western blot analysis was used to detect the protein expressions of β-catenin and Cyclin D1,which were key components of the Wnt/β-catenin signaling pathway.Results In MEC-1 cells:① compared with the control group,there was a increased miR-34a-5p expression and inhibited cell proliferation in the p53 agonist group(P＜0.05).Dual-luciferase reporter assay confirmed a negative regulatory correlation between miR-34a-5p and p53.② the miR-34a-5p mimic group showed significantly upregulated miR-34a-5p expression compared to the control group,leading to suppressed cell proliferation,reduced migration capability and decreased protein expressions of β-catenin and Cyclin D1(P＜0.05).Conversely,the miR-34a-5p inhibitor group demonstrated significantly downregulated miR-34a-5p expression,resulting in enhanced cell proliferation,increased migratory capacity and upregulated protein levels of β-catenin and Cyclin D1 compared to those of the control group(P＜0.05).③ A targeting relationship was observed between miR-34a-5p and Wnt1.④ Compared with the miR-34a-5p inhibitor group,the XAV-939 group exhibited significantly upregulated miR-34a-5p expression,markedly decreased numbers of migrated cells and substantially reduced protein expression levels of β-catenin and Cyclin D1(P＜0.05).Conclusion miR-34a plays the role of a tumor suppressor gene in CLL.Overexpression of miR-34a can inhibit the Wnt/β-catenin signaling pathway,reduce the proliferation activity and migration ability of cells,and promote cell apoptosis.

Perimenopausal women are more susceptible to fire pathogen disturbances,often resulting in the restlessness of the mind owing to the deficiency and decline of the thoroughfare and conception vessels,as well as the insufficiency of the essence and blood of the viscera.CHENG Zhongling's theory of thief and child fire in Medical Insights proposes that thief fire primarily arises from exogenous pathogen invasion and improper diet,leading to syndromes such as food retention in the stomach or phlegm-fire stagnation.In contrast,child fire is generated endogenously,often owing to liver and kidney deficiency,resulting in an imbalance of water and fire and liver dysfunction,leading to excessive fire transformation.This theory provides a novel perspective for understanding the pathogenesis of perimenopausal insomnia.An in-depth exploration of the role of thief fire and child fire in perimenopausal insomnia is presented,along with a detailed discussion of corresponding treatment strategies.For the invasion of thief fire,therapeutic approaches include ascending and dispersing stagnant fire,clearing and moistening to remove interior heat,purging the heat accumulation to unblock the bowels,and subduing the fire and nourishing yin to eliminate depression.When child fire disturbs the spirit,treatment methods involve smoothing and relieving the liver qi to clear the stagnant heat,nourishing the true yin to restrain the yang,warming and nurturing the primordial qi and harmonizing the nutrient and defensive qi,and guiding and reducing the deficient heat to remove the floating fire.Clinical practice necessitates precise identification of thief and child fire,thorough investigation of exogenous pathogens and internal damage,and careful differentiation between deficiency and excess,as well as the superficial and internal aspects.Strict adherence to the treatment principle of"nourishing the child fire can drive out the thief fire,but driving out the thief fire should not harm the child fire"ensures a balanced approach.By harmonizing the yin and yang of the viscera and allowing the mind to be at ease,this strategy effectively alleviates perimenopausal insomnia.The application of these principles provides a practical and feasible theoretical foundation and practical guidance for the treatment of perimenopausal insomnia using traditional Chinese medicine.
