Chronic heart failure （CHF） is a major global public health problem， and myocardial infarction is one of its main causes. The mouse model of heart failure induced by coronary artery ligation is widely used in the study of CHF， while the TCM syndrome attributes of this model have not yet been clarified. According to the theory of correspondence between prescriptions and syndromes， the method of syndrome identification by prescription efficacy is an important means of current syndrome research of animal models. This method deduces the syndrome characteristics of animal models through prescription efficacy. Taking the four basic syndrome elements of Qi， blood， Yin and Yang as the classification reference， this study used coronary artery ligation to construct a mouse model of CHF and treated the model with four representative TCM injections with the effects of replenishing Qi， warming Yang， nourishing Yin， and activating blood and enalapril. Echocardiography， tongue color parameters， histopathology， serum N-terminal pro-brain natriuretic peptide （NT-proBNP） and cardiac troponin Ⅰ （cTnⅠ） levels， and systematically explored the TCM syndrome attributes of this model. The results showed that the coronary ligation model presented an obvious cardiac function decline， myocardial fibrosis， infarct size expansion， and purple dark tongue， which were consistent with the basic syndrome characteristics of blood stasis in CHF. Danhong injection had significant effects of improving the cardiac function， alleviating myocardial fibrosis， and reducing serum NT-proBNP and cTnⅠ levels. Huangqi Injection and Shenfu injection can improve the cardiac function and tongue color parameters， with limited effects. The effect of Shenmai injection group was not obvious. This study verifies that the established model conforms to blood stasis syndrome through the method of syndrome identification by prescription efficacy， which provides an experimental basis for the study of TCM syndrome mechanism of CHF.

ObjectiveTo examine the influences of Shenfu injection on the endogenous metabolic byproducts in the myocardium of the rat model exhibiting chronic heart failure， thus deciphering the therapeutic mechanism of the Qi-reinforcing and Yang-warming method. MethodsSD rats were randomly allocated into a control group and a modeling group. Chronic heart failure with heart-Yang deficiency syndrome in rats was modeled by multi-point subcutaneous injection of isoproterenol， and the rats were fed for 14 days after modeling. The successfully modeled rats were randomized into model， Shenfu injection （6.0 mL·kg^-1）， and trimetazidine （10 mg·kg^-1） groups and treated with corresponding agents for 15 days. The control group and the model group were injected with equal doses of normal saline， and the samples were collected after the intervention was completed. Cardiac color ultrasound was performed. Hematoxylin-eosin （HE） staining was used to observe histopathological morphology， and the serum level of N-terminal pro-brain natriuretic peptide （NT-proBNP） was assessed by enzyme-linked immunosorbent assay （ELISA）. The mitochondrial morphological and structural changes of cardiomyocytes were observed by transmission electron microscopy， and the metabolic profiling was carried out by ultra high performance liquid chromatography-quantitative exactive-mass spectrometry （UHPLC-QE-MS）. Differential metabolites were screened and identified by orthogonal partial least squares-discriminant analysis （OPLS-DA） and other methods， and then the MetaboAnalyst database was used for further screening. The relevant biological pathways were obtained through pathway enrichment analysis. The receiver operating characteristic （ROC） curve was established to evaluate the diagnostic value of each potential biomarker for myocardial injury and the evaluation value for drug efficacy. ResultsThe results of color ultrasound showed that Shenfu Injection improved the cardiac function indexes of model rats （P<0.05）. The results of HE staining showed that Shenfu injection effectively alleviated the pathological phenomena such as myocardial tissue structure disorder and inflammatory cell infiltration in model rats. The results of ELISA showed that Shenfu injection effectively regulated the serum NT-proBNP level in the model rats. Transmission electron microscopy （TEM） showed that Shenfu injection effectively restored the mitochondrial morphological structure. The results of metabolomics showed that the metabolic phenotypes of myocardial samples presented markedly differences between groups. Nine differential metabolites could be significantly reversed in the Shenfu injection group， involving three metabolic pathways： pyruvate metabolism， histidine metabolism， and citric acid cycle （TCA cycle）. The results of ROC analysis showed that the area under the curve （AUC） values of all metabolites were between 0.75 and 1.0， indicating that the differential metabolites had high diagnostic accuracy for myocardial injury， and the changes in their expression levels could be used as potential markers for efficacy evaluation. ConclusionShenfu injection significantly alleviated the damage of cardiac function， myocardium， and mitochondrial structure in the rat model of chronic heart failure with heart-Yang deficiency syndrome by ameliorating energy metabolism remodeling. Reinforcing Qi and warming Yang is a key method for treating chronic heart failure with heart-Yang deficiency syndrome.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

[Objective] To explore the clinical significance and application value of establishing a database for red blood cell alloantibody detection. [Methods] Patients who were scheduled for blood transfusion in our hospital from January 1, 2020 to May 1, 2024 were selected as the research subjects. A red blood cell alloantibody detection database was established using Microsoft Office Excel software to register the detection data of patients' alloantibodies and antibodies of undetermined specificity (AUS). A retrospective analysis was conducted on the clinical characteristics, antibody distribution, antibody decay and repeat positivity of the patients in the database. The LISS-IAT method was routinely used for antibody screening and identification. [Results] Among the alloantibodies, the Rh blood group system had the highest detection rate, followed by antibodies of the MNS blood group system and the Lewis blood group system. The predominant antibody in the Rh blood group system was anti-E. In the univariate analysis, the positivity of antibody was significantly associated with the patient's gender, age, blood transfusion history, pregnancy history and type of disease (all P<0.001). In the database, 48 patients experienced antibody decay, accounting for 15.24%(48/315), with an average time span of antibody decay ranging from 22 to 1 324 days. Six cases showed repeat positivity after decay, which were related to blood transfusions. The shortest interval between blood transfusions that led to antibody repeat positivity was 3 days, and the longest interval was 427 days. Among 58 cases with AUS, 3 converted into alloantibodies, among which 2 were anti-E and 1 was anti-Lea. [Conclusion] Establishing a red blood cell alloantibody detection database is an effective way to guide ambiguous cross-matching in clinical practice and is also an effective measure for the management of transfusion risks.

Objective: To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD. Methods: From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test. Results: At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00，24.00)，9.00(8.00，13.00)] were significantly higher than those of the control group [12.00(-1.00，18.00)，2.00(-2.00，7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%，(76.86±12.06)%，(79.61±12.42)%，(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%，(62.82±18.77)%，(67.18±18.85)%，(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05). Conclusion Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

Lipocalin-2 (LCN2), a member of the human lipocalin family, has been demonstrated to be closely associated with diabetes, cardiovascular diseases, and renal disorders.

Methods: Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups. Results: The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3). Conclusion The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.

Energy metabolism reconstruction is the new target of the treatment of heart failure. By combing the researches of Chinese medicinals for energy metabolism reconstruction of heart failure， it was found that Chinese medicinal compound formula and single Chinese medicinal have a certain role in regulating energy metabolism， mainly through three aspects， including the optimization of substrate utilization， improvement of mitochondrial structure， function， and homeostasis， and improvement of mitochondrial energy transport， so as to make the energy metabolism of the cardiomyocyte adjusted in the direction of beneficial to the organism， increasing the supply of energy， and improving the cardiac function.

Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

ObjectiveThis study aims to explore the mechanism and targets of Shenfu Injection in regulating glycolysis to intervene in myocardial fibrosis in chronic heart failure based on the hypoxia-inducible factor-1α （HIF-1α）/ 6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 3 （PFKFB3） signaling pathway. MethodsA rat model of chronic heart failure was established by subcutaneous injection of isoproterenol （ISO）. After successful modeling， the rats were randomly divided into the Sham group， Model group， Shenfu injection （SFI， 6 mL·kg^-1） group， and inhibitor （3PO， 35 mg·kg^-1） group， according to a random number table， and they were treated for 15 days. Cardiac function was evaluated by echocardiography， and serum N-terminal pro-brain natriuretic peptide （NT-proBNP） levels were detected by enzyme-linked immunosorbent assay （ELISA）. Fasting body weight and heart weight were measured， and the heart index （HI） was calculated. Pathological changes in myocardial tissue were observed by hematoxylin-eosin （HE） and Masson staining， and the fibrosis rate was calculated. Biochemical assays were used to determine serum levels of glucose （GLU）， lactic acid （LA）， and pyruvic acid （PA）. Western blot was used to analyze the expression of proteins related to the HIF-1α/PFKFB3 signaling pathway （HIF-1α and PFKFB3）， glycolysis-related proteins （HK1， HK2， PKM2， and LDHA）， and fibrosis-related proteins ［transforming growth factor （TGF）-β₁， α-smooth muscle actin （α-SMA）， and Collagen type Ⅰ α1 （ColⅠA1）］. Real-time PCR was used to detect the mRNA expression of HIF-1α and PFKFB3 in myocardial tissue. ResultsCompared with the Sham group， the Model group showed significantly decreased left ventricular ejection fraction （LVEF）， left ventricular shortening fraction （LVFS）， interventricular septal thickness （IVSd）， and interventricular septal strain （IVSs） （P<0.05）， while left ventricular internal dimension at end-diastole （LVDd） and end-systole （LVIDs） were increased （P<0.05）. Serum NT-proBNP levels were significantly increased （P<0.01）， and body weight was decreased. Heart weight was increased， and the HIT index was increased （P<0.05）. Myocardial tissue exhibited inflammatory cell infiltration and collagen fiber deposition， and the fibrosis rate was significantly increased （P<0.05）. Serum GLU was decreased （P<0.05）， while LA and PA levels were increased （P<0.05）. Protein expressions of HIF-1α， PFKFB3， HK1， HK2， PKM2， LDHA， TGF-β₁， α-SMA， and ColⅠA1， as well as the mRNA expression of HIF-1α and PFKFB3 were increased （P<0.05）. Compared with the Model group， both the SFI group and 3PO groups showed significant improvements in LVEF， LVFS， IVSd， and IVSs （P<0.05） and decreases in LVDd， LVIDs， and NT-proBNP levels （P<0.05）. Body weight was significantly increased. Heart weight was significantly decreased， and the HIT index was significantly decreased （P<0.05）. Inflammatory cell infiltration， collagen fiber deposition， and the fibrosis rate were significantly decreased （P<0.05）. Serum GLU levels were significantly increased （P<0.05）， while LA and PA levels were decreased （P<0.05）. Expressions of glycolysis-related proteins， fibrosis-related proteins， and HIF-1α/PFKFB3 pathway-related proteins and mRNAs were significantly suppressed （P<0.05）. ConclusionSFI improves cardiac function in chronic heart failure by downregulating the expression of HIF-1α/PFKFB3 signaling pathway-related proteins， regulating glycolysis， and inhibiting myocardial fibrosis.
