To summarize Professor WANG Jianmin's experience in cathartic colon from "keeping sweet to return liquid". It is believed that the key to the pathogenesis of cathartic colon is fluid consumption and intestinal dryness， including yin depletion of spleen earth， and lack of sources for body fluids production； discordance of water and fire in kidneys， and irregular distribution of body fluids； and closure of the lungs and liver leads to inability of the flow of fluids. The treatment is based on the principle of "keeping sweet to return liquid"， using sweet medicinals mainly， assistant with sour， bland and acrid medicinals， and self-prescribed Lipi Shengjin Decoction （理脾生津汤）， Wenshen Runchang Decoction （温肾润肠汤）， Kaifei Shunchang Decoction （开肺顺肠汤）， Rougan Tongbian Decoction （柔肝通便汤） could be used to regulate spleen yin by the sweet and bland， and establish qi and promote fluid production； the sweet and warm medicinals can replenish water and fire， transform into qi， and distribute body fluids； the acrid and sweet can open lung depression， descend qi， and flow the body fluids； the sour and sweet can emolliate liver， move qi， and transform fluids.

ObjectiveTo observe the clinical effectiveness and safety of Dingchan Granule （定颤颗粒） for paroxysmal atrial fibrillation with syndrome of qi stagnation and blood stasis. MethodsUsing a randomised， double-blind， placebo controlled study method， 90 patients with paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome were divided into 45 cases each in the treatment group and the control group. Both groups were given conventional western medicine treatment， and the treatment group was additionally treated with Dingchan Granule， while the control group was treated with Dingchan Granule placebo， both of which were taken orally for 8 g each time twice a day. Both groups were treated for 8 weeks. We compared the clinical effectiveness， the improvement of traditional Chinese medicine （TCM） symptoms and the recovery rate of atrial fibrillation between the two groups. We compared the number and duration of atrial fibrillation episodes， TCM symptoms score， atrial fibrillation symptom classification， 24-hour average ventricular rate， Pittsburgh Sleep Quality Index （PSQI）， anxiety index， depression index before and after treatment， and evaluated the safety of the two groups. ResultsThe total clinical effectiveness rate in the treatment group was 82.22% （37/45）， which was better than 60.00% （27/45） in the control group （P＜0.05）. The total effective rate of TCM syndrome effectiveness in the treatment group was 88.89% （40/45）， which was better than 66.67% （30/45） in the control group （P＜0.05）； and the rate of atrial fibrillation regression in the treatment group was 26.67% （12/45）， better than 6.67% （3/45） in the control group （P＜0.05）. The number and duration of atrial fibrillation episodes in both groups were significantly decreased （P＜0.01）， and the number and duration of atrial fibrillation episodes in the treatment group were lower than those in the control group （P＜0.01）. The TCM syndrome scores of both groups after treatment were significantly lower than before treatment （P＜0.01）， and the scores of the treatment group was lower than those of the control group （P＜0.05）. The severity of atrial fibrillation symptoms and the grading of atrial fibrillation symptoms in both groups after treatment were improved （P＜0.01）， and the degree of symptom improvement in the treatment group was better than that in the control group （P＜0.01）. The 24-hour average ventricular rate of both groups after treatment was significantly lower （P＜0.01）. The PSQI， anxiety index and depression index of the treatment group were all lower than before treatment （P＜0.01）， while the PSQI and anxiety index of the control group were both lower than before treatment （P＜0.01 or P＜0.05）， the PSQI， anxiety index and depression index of the treatment group being lower than those of the control group （P＜0.05 or P＜0.01）. No adverse events occurred in both groups， and no abnormalities were observed in blood， urine， stool routine， liver and kidney function， and coagulation function indexes. ConclusionDingchan Granule for paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome can alleviate clinical symptom， improve TCM symptom scores， increase atrial fibrillation recovery rate， stabilise the average ventricular rate， and significantly improve the quality of sleep， alleviate the anxiety and depression， with a good safety profile.

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 biological functions and mechanisms of PIWI-interacting RNA(piRNA)in cervical cancer(CC).Methods RT-qPCR was used to detect the expression level of piRNA-2732 in CC tissue,CaSki cells and End1/E6E7 cells.EpiQuik m6A RNA methylation quantification kit was used to detect the methylation level of m6A RNA in CaSki cells.The expression levels of methyltransferases(METTL3,METTL14 and WTAP)and demethylases(FTO,ALKBH5)mRNA in CaSki cells were detected by RT-qPCR.After culturing CaSki cells to logarithmic growth stage,they were divided into six groups:piRNA-2732 mimic negative control group(mi-NC group),piRNA-2732 mimic group(mi-2732 group),piRNA-2732 inhibitor negative control group(in-NC group),piRNA-2732 inhibitor group(in-2732 group),piRNA-2732 mimic+METTL3 knockdown control group(mi-2732+si-NC group),and piRNA-2732 mimic+METTL3 knockdown group(mi-2732+si-METTL3 group).The viability of CaSki cells was detected by CCK8 assay.Colony formation assay was used to detect the proliferation ability of CaSki cells.Transwell experiment was used to detect the migration and invasion ability of CaSki cells.RT-qPCR and Western blot were used to detect the expression of methyltransferase like protein 3(METTL3).Transfected METTL3 wild-type(METTL3-WT)and METTL3 mutant(METTL3-MUT)in the mi-NC group,mi-2732 group,in-NC group,and in-2732 group respectively,and detected the effect of piRNA-2732 on METTL3 through dual luciferase reporter gene assay.Results Compared with the adjacent tissues,the expression of piRNA-2732(3.84±1.08 vs 1.32±0.53)was significantly higher in the cancer tissues of CC patients,and the difference was statistically significant(t=5.115,P<0.001).Compared with end1/E6E7 cells,the expression of piRNA-2732(1.00±0.13 vs 1.67±0.16)in CaSki cells was significantly higher,and the difference was statistically significant(t=5.632,P<0.01).Compared with mi-NC group,mi-2732 group promoted the viability,proliferation,migration and invasion of CaSki cells,and the differences were statistically significant(t=4.410～11.040,all P<0.01).Compared with mi-NC group,mi-2732 group increased m6A RNA methylation level and METTL3 mRNA and protein,the differences were statistically significant(t=6.176,9.211,12.550,all P<0.05).The results of dual luciferase reporter gene testing showed that compared with the mi-NC+METTL3-WT group,the relative luciferase activity of mi-2732+METTL3-WT group was significantly increased(t=11.850).Compared with mi-2732+METTL3-WT group,the relative luciferase activity of mi-2732+METTL3-MUT group was significantly lower(t=12.740),and the difference was statistically significant(all P<0.000 1).Compared with in NC+METTL3-WT group,the relative luciferase activity of in-2732+METTL3-WT group was significantly lower(t=7.828),compared with in-2732+METTL3-WT group,the relative luciferase activity of CaSki cells in in-2732+METTL3-MUT group was significantly increased(t=8.146),and the difference was statistically significant(all P<0.001).Compared with mi-2732+si-NC group,the expression level of m6A in mi-2732+si-METTL3 group was significantly lower,and the difference was statistically significant(t=7.630,P<0.01).Compared with mi-2732+si-NC group,the proliferation ability,colony number,cell migration and invasion ability of CaSki cells in mi-2732+si-METTL3 group were significantly decreased,and the differences were statistically significant(t=3.695～4.891,all P<0.001).Conclusion piRNA-2732 is overexpressed in CC tissues and cells,and piRNA-2732 promotes tumor development in CC through METTL3 mediated m6A methylation.

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.

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 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.

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.
