Objective:To explore the funding status and research hotspots of the National Natural Science Foundation of China (NSFC) for projects in the field of TCM for the prevention and treatment of heart failure.Methods:The research projects of TCM in the prevention and treatment of heart failure funded were retrieved from NSFC Big Data Knowledge Management Service Platform from January 1, 2010 to December 31, 2023. Excel 2022 software was used to analyze the data of the number of funded projects, the amount of funding, the supporting units and the regions. VOSviewer 1.6.20 software was used to analyze the co-occurrence of keywords with frequency≥3.Results:A total of 202 research projects were funded with a total funding amount of 89.8 million RMB, and the number and amount of projects showed a fluctuating upward trend. The funding categories were mainly general programs and youth science foundation projects. There were 42 supporting units involved, and TCM universities and colleges were the main recipients of funding. Regional distribution was uneven, mainly in Beijing, Shanghai, Guangdong and other regions. There were 17 secondary discipline codes involved, and the discipline categories were concentrated in Internal Medicine of TCM (H3108), Clinical Basis of Integrative Medicine (H3302) and Cardiovascular Pharmacology of Chinese Medicine (H3209). Therapeutic modalities covered compounding, monomers, proprietary Chinese medicines, and drug pairs, and research hotspots included aspects of myocardial energy metabolism remodeling, mitochondrial autophagy, macrophage polarization, endoplasmic reticulum stress, calcium homeostasis, ferroptosis, exosomes, micro-RNAs, and so on.Conclusion:NSFC has provided strong support to the research in the field of TCM for heart failure. In the future, the supporting units should pay attention to the interdisciplinary integration and development to promote the vigorous development of TCM.

Objective To explore the risk factors for the recurrence of autoimmune pancreatitis(AIP),so as to provide a new reference for its clinical treatment.Methods The clinical data of 198 AIP patients admitted to The First Affiliated Hospital of Naval Medical University from 2014 to 2021 were collected,including 164 patients with type 1 AIP and 34 patients with type 2 AIP.Based on the recurrence status of AIP,the patients were categorized into recurrence group(38 cases)and non-recurrence group(160 cases),and differences between the 2 groups were analyzed.Patients with definite duration of glucocorticoid maintenance therapy were further screened,and logistic regression model and Spearman rank correlation analysis were used to analyze the risk factors of AIP recurrence.Results During the follow-up period,19.19％(38/198)of AIP patients experienced a relapse.The 1-,3-,and 5-year cumulative recurrence rates were 6.57％,9.09％,and 12.63％,respectively,with type 1 AIP demonstrating a significantly higher recurrence rate than type 2 AIP(21.95％[36/164]vs 5.88％[2/34],P=0.030).Univariate logistic regression analysis showed that serum low density lipoprotein-cholesterol level(odds ratio[OR]=0.544,95％confidence interval[CI]0.321-0.924,P=0.024)and the duration of glucocorticoid maintenance therapy(OR=0.797,95％CI 0.704-0.902,P＜0.001)were the potential factors of AIP recurrence in 112 patients with definite data on the duration of glucocorticoid maintenance therapy.Multivariate logistic regression analysis showed that the duration of glucocorticoid maintenance therapy was independently associated with AIP recurrence(OR=0.813,95％CI 0.713-0.926,P=0.002).Spearman rank correlation analysis further demonstrated a negative correlation between the duration of glucocorticoid maintenance therapy and AIP recurrence(r=-0.545,P＜0.001).Additionally,receiver operating characteristic curve analysis indicated that the duration of glucocorticoid maintenance therapy had good predictive effect on AIP recurrence,with an area under curve value of 0.873(95％CI 0.800-0.945,P＜0.001).Conclusion Long-term regular glucocorticoid therapy is an independent protective factor against AIP recurrence,and it can significantly reduce the recurrence of AIP.

Myocardial fibrosis （MF） is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells， the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself， and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research， scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system （RAAS） system and the inflammatory process， repairing the extracellular matrix， managing oxidative stress， and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process， macrophage activation is beneficial， but excessive activation will be harmful. In the early stage of MF， appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF， appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient， or the balance of M1/M2 macrophage polarization is broken， the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin， as well as regulating Qi and activating blood， but there are also some heat-clearing， dampness-drying， and detoxification products. Therefore， the occurrence of MF may be caused by Qi and Yin deficiency， damp heat accumulation， and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF， this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF， so as to provide a reference for the treatment of MF with traditional Chinese medicine.

Objective : To analyze the status of glucose metabolism in obese children． Methods : 266 cases of obese children were included in the study，fasting plasma glucose ( FPG) ，fasting insulin ( FINS) ，glycosylated hemoglobin ( HbA1c) were measured ，Oral glucose tolerance test ( OGTT) and insulin release test ( IRT) were carried out，insulin resistance index ( HOMA-IR) ，quantified insulin sensitivity index ( QUICKI) and peak insu- lin /fasting insulin (Ip / I0 ) were calculated．Two hundred non-obese healthy children were used as control group， and glucose metabolism indexes were compared between the two groups． Glucose metabolism indexes and the incidence of insulin resistance (IR) were compared in children with different degrees of obesity ．Prediabetes risk factors and body mass index(BMI) correlation were analyzed in obese children. Results : The proportion of predia- betes and type 2 diabetes mellitus in obese children was 18. 0% (48 /266) ．FINS，HOMA-IR and HbA1c in obesi- ty group were higher than those in the control group，but QUICKI was lower than that in the control group (P < 0. 05) ．There was no significant difference in FPG between the two groups (P = 0. 423) ．FINS and HOMA-IR of severe obesity group were higher than those of mild to moderate obesity group，Ip / I0 was lower than that of mild to moderate obesity group (P＜0. 05) ，and there was no significant difference in FPG，QUICKI，HbA1c and 2hPG of severe obesity group．There was no significant difference in IR incidence between mild to moderate obesity group and severe obesity group (P = 0. 163) ．Logistic regression indicated that BMI and acanthosis nigricans was great influential on prediabetes with no statistical significance(P＞0. 05) ．Correlation analysis showed that BMI had no correlation with FPG (P = 0. 160) ，but was positively correlated with FINS，HOMA-IR , 2hPG and HbA1c (P < 0. 05) ，and negatively correlated with QUICKI and Ip / I0 (P＜0. 05) ． Conclusion Abnormal glucose metabolism is available in nearly 20% of obese children．The prevalence of insulin resistance in obese children is not affected by the degree of obesity.
