Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

AIM: To evaluate the application value of artificial intelligence-assisted systems in diagnosing diabetic retinopathy(DR)by Meta-analysis.METHODS: PubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI, WanFang Data and VIP database were searched to collect relevant literature on the diagnostic value of artificial intelligence-assisted systems for DR from January 2019 to September 2024. The QUADAS-2 tool was used to evaluate the quality of the included studies, and Meta-analysis was performed using Stata 17.0 and Meta Disc 1.4 software.RESULTS: A total of 23 studies were included. The results of Meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio were 0.92(95% CI: 0.89-0.94), 0.94(95% CI: 0.91-0.96), 15.6(95% CI: 10.6-22.9), 0.09(95% CI: 0.07, 0.12), 174(95% CI: 112-271), respectively, and the area under the ROC curve(AUC)was 0.97(95% CI: 0.96-0.98). Meta-regression and subgroup analyses indicated that the heterogeneity of the studies originated from study type, patient type, patient source, and AI algorithm type. Deeks' funnel plot test suggested no significant publication bias(P=0.15), indicating that the results were robust.CONCLUSION: The artificial intelligence-assisted system demonstrates high diagnostic value for DR, and can be widely implemented in the early screening and diagnosis of DR.

OBJECTIVE To investigate the ameliorative effects and potential mechanism of total secondary ginsenosides （TSG） on hypertrophic changes of primary cardiomyocytes stimulated by angiotensin Ⅱ （Ang Ⅱ）. METHODS Primary cardiomyocytes were isolated from the hearts of neonatal SD rats and divided into the following groups： control group， AngⅡ group （2 µmol/L）， TSG group （7.5 µg/mL）， PFK-015 group [6-phosphofructo-2-kinase/fructose-2， 6-bisphosphatase 3 （PFKFB3） inhibitor， 10 nmol/L]， and TSG+PFK-015 group （TSG 7.5 µg/mL+PFK-015 10 nmol/L）. The surface area， protein synthesis， energy metabolism-related indicators [free fatty acid （FFA）， coenzyme A （CoA）， acetyl coenzyme A （acetyl-CoA）]， and the expressions of glycolysis-related factors [hypoxia-inducible factor 1α （HIF-1α）， glucose transporter protein 4 （GLUT-4）， lactate dehydrogenase A （LDHA）， pyruvate dehydrogenase kinase 1 （PDK1） and PFKFB3] in primary cardiomyocytes of each group were measured. RESULTS Compared with the control group， the surface area of primary cardiomyocytes and protein synthesis were significantly increased， the content of FFA， protein and mRNA expressions of HIF-1α， LDHA， PDK1 and PFKFB3 were significantly increased or up-regulated in the AngⅡ group， while the contents of CoA and acetyl-CoA， the protein and mRNA expressions of GLUT-4 were significantly decreased or down-regulated （P＜0.05）. Compared with the AngⅡ group， both TSG group and PFK-015 group showed significant improvements in these indexes， with the TSG+PFK-015 group generally demonstrating superior effects compared to either treatment alone （P＜0.05）. CONCLUSIONS TSG can reduce the surface area of AngⅡ-induced primary cardiomyocytes， decrease protein synthesis， and inhibit their hypertrophic changes. These effects may be related to improving energy metabolism and the inhibition of glycolysis activity.

Objective:To analyze the role of learning engagement and learning burnout in the relationship between supervisors' guidance and the personal ability of postgraduates in the Professional Master's Program in Clinical Medicine.Methods:A total of 4 016 postgraduates in the Professional Master's Program in Clinical Medicine from 61 colleges were surveyed in 2020. Common method bias was assessed using the Harman's single factor test and total score was determined by the entropy weight method. Causality and mediation effect were analyzed by linear regression, and mediation effect was tested by Bootstrapping.Results:The average scores of supervisors' guidance, learning burnout, learning engagement and personal ability were (4.13±0.87), (2.49±1.11), (3.88±0.83), and (3.71±0.78), respectively. Supervisors' guidance significantly and positively impacted learning engagement ( β=0.689, P<0.001) and personal ability ( β=0.504, P<0.001). Learning engagement played a partial mediating role (89.30% of mediation effect) between supervisors' guidance and personal ability. Learning burnout (interaction term β=0.078, P<0.001) positively regulated the relationship between supervisors' guidance and learning engagement. Conclusions:Learning engagement can mediate the effect of supervisors' guidance on the personal ability of postgraduates in the Professional Master's Program in Clinical Medicine, and learning burnout positively regulates the effect of supervisors' guidance on learning engagement. Strengthened supervisors' guidance, increased attention to students' learning burnout, and enhanced learning engagement can further improve the personal abilities of postgraduates in the Professional Master's Program in Clinical Medicine.

Objective:To investigate the "burnout-engagement continuum" status of postgraduate supervisors of the Professional Master's Program in Clinical Medicine and to identify key populations.Methods:From October to November 2023, an anonymous online questionnaire survey was conducted to determine the "burnout-engagement continuum" status of postgraduate supervisors of the Professional Master's Program in Clinical Medicine. The scores of different dimensions of job burnout are expressed as mean±standard deviation, and the distribution of supervisors of different status is presented in frequency and percentage. All data analyses were performed in R 4.3.1. Distribution of the five profiles among supervisors of different status was compared using the chi-square test and compared pairwise using the Bonferroni method.Results:A total of 2 664 valid questionnaires were collected. The scores of emotional exhaustion, cynicism and personal accomplishment were（2.46±0.95),（1.74±0.89), and（4.23±0.90), respectively. The prevalence of job engagement, inefficacy, overexertion, disengagement, and burnout among the supervisors were 42.76%（1 139/2 664), 43.54%（1 160/2 664), 33.03%（880/2 664), 14.71%（392/2 664), and 13.66%（364/2 664), respectively. In terms of demographics, the distribution of the "burnout-engagement continuum" was significantly different by age, sex, marital status, and highest education level（ P<0.05). In terms of work-related characteristics, the distribution of the "burnout-engagement continuum" was significantly different by income, professional title, administrative position, and working hours on weekdays and holidays（ P<0.05). The distribution of engagement, inefficacy, and overexertion was significantly different between the eastern and western regions（ P<0.05). Conclusions:There is a high percentage of individuals with burnout among postgraduate supervisors of the Professional Master's Program in Clinical Medicine, and inefficacy is a common negative state. Supervisors who work in the western regions, are under 45 years of age, are male, are married, have a doctorate degree, hold associate senior professional title, have lower relative income, are not holding administrative duties, and work more than 10 hours on workdays and more than 4 hours on holidays are key populations that require increased attention. The psychological state of supervisors can be improved by providing them with more resources, work benefits, and incentives.

Objective:To understand the evaluation of graduate education quality by medical graduate supervisors in China, to identify the shortcomings of graduate education quality, and to put forward corresponding suggestions.Methods:From October to November 2023, a self-designed questionnaire was used to investigate the evaluation of school management, supervisor team construction, graduate training process, and graduate training results by 6 025 medical graduate supervisors from 37 universities in China. SPSS 26.0 was used to conduct t-test and analysis of variance to explore the differences in scores given by different supervisor groups for various aspects. Results:The scores given by medical graduate supervisors for school management, supervisor team construction, graduate training process, and graduate training results were (4.63±0.60), (4.59±0.62), (4.58±0.59), and (4.54±0.62), respectively. Supervisors who work in clinical medicine, aged 46-55 years, with 5 or fewer years of teaching experience, supervising master's students, instructing only professional degree students, instructing three or fewer students, holding a bachelor's degree as their highest degree, with the title of professor, holding an administrative position, and working an average of 8-9 hours per day on weekdays and 4 or fewer hours per day on holidays, gave higher scores on all aspects of graduate education quality ( P<0.05). Conclusions:The supervisors gave high scores on the quality of medical graduate education. It is suggested that the quality of graduate education should be continuously improved by optimizing school management systems, strengthening the construction of supervisory teams, and focusing on the process and results of graduate education.

Objective:To investigate the enrollment scale and distribution of Master's Degree in Pediatrics programs in China, and to provide a reference for promoting pediatric education and disciplinary development.Methods:Data on colleges and universities authorized to award Master's Degree in Pediatrics in 2023 were collected, sorted, and analyzed for the number, structure, distribution, and enrollment scale and direction of these institutions using descriptive statistics.Results:Among the 117 clinical medicine academic master's degree programs in China, 72 enroll pediatric academic master's degree candidates, with an enrollment of 260 students. Among the 120 master's degree programs in clinical medicine, 104 enroll professional master's degree candidates, enrolling 1 195 students. Enrollment is mainly concentrated in East China, "non-double first-class" colleges and universities, medical colleges and universities with subject level B, and enrollment is carried out in the direction of secondary disciplines.Conclusions:The number of colleges and universities authorized to award Master's Degree in Pediatrics was small, and the distribution of these colleges and universities was unbalanced. The enrollment scale was small and the orientation of Professional Master's Degree was not reasonable. Some colleges and universities were authorized to award Master's Degree in Pediatrics, but did not enroll any students. It is suggested to increase the number of colleges and universities authorized to award Master's Degree in Pediatrics and strengthen the staffing of pediatric departments. The aim is to expand the enrollment scale of candidates for Master's Degree in Pediatrics, improving the differential training of candidates for Academic Master's Degree and Professional Master's Degree, and attach importance to the construction of pediatrics.

Epitranscriptomics focuses on the RNA-modification-mediated post-transcriptional regulation of gene expression. The past decade has witnessed tremendous progress in our understanding of the landscapes and biological functions of RNA modifications, as prompted by the emergence of potent analytical approaches. The hematopoietic system provides a lifelong supply of blood cells, and gene expression is tightly controlled during the differentiation of hematopoietic stem cells (HSCs). The dysregulation of gene expression during hematopoiesis may lead to severe disorders, including acute myeloid leukemia (AML). Emerging evidence supports the involvement of the mRNA modification system in normal hematopoiesis and AML pathogenesis, which has led to the development of small-molecule inhibitors that target N6-methyladenosine (m 6A) modification machinery as treatments. Here, we summarize the latest findings and our most up-to-date information on the roles of m 6A and N7-methylguanine in both physiological and pathological conditions in the hematopoietic system. Furthermore, we will discuss the therapeutic potential and limitations of cancer treatments targeting m 6A.

Aim To investigate the effect and role of neuronal restriction silencing factor(REST/NRSF)in epilepsy disorder.Methods Immunohistochemistry,immunofluorescence,Western blot and qPCR tech-niques were used to detect REST/NRSF expression levels in hippocampal tissues of mice induced by kainic acid and human brain tissue.Viral injections,EEG re-cordings and behavioral methods were used to test the effects on epileptic mice after knockdown and overex-pression of REST/NRSF in the hippocampal CA1 re-gion,respectively.Results The positive rate of REST/NRSF in the lesions of epileptic patients was significantly higher compared with that in the control group.The levels of REST/NRSF protein and mRNA in the CA1 region of the hippocampus of mice in the KA model group were significantly higher.Kv7.2 and Kv7.3 potassium channel mRNA expression levels were significantly down-regulated.Significant up-regu-lation of REST/NRSF expression levels was observed in mouse hippocampus after NMDA injection.Knock-down of REST/NRSF in the CA1 region of hippocam-pus significantly elevated the expression levels of Kv7.2 and Kv7.3 potassium channel mRNAs.The fre-quency of EEG spiking and sharp-wave issuance and epileptic seizure grade were significantly lower.Over-expression of REST/NRSF in the CA1 region of hippo-campus significantly reduced the mRNA expression lev-els of Kv7.2 and Kv7.3 potassium channels.The fre-quency of EEG spiking and sharp-wave issuance was significantly higher and epileptic symptoms were exac-erbated.Conclusion REST/NRSF in mouse hipp-ocampal brain regions is involved in epileptic disease development through transcriptional regulation of Kv7.2 and Kv7.3 potassium channels.
