ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Based on the previous publications， it is believed that damp-heat syndrome is the core syndrome of rheumatoid arthritis （RA）， and Qingre Huoxue Formula （清热活血方） is an effective formula for the treatment of damp-heat syndrome of RA. “Inflammation-bone destruction” is a key pathological link of RA， and it is also the advantage of the effectiveness of Qingre Huoxue Formula. Leucine rich α-2-glycoprotein 1 （LRG1） can mediate the transforming growth factor-β （TGF-β） signalling pathway to participate in the pathogenic process of “inflammation-bone destruction” of RA， and it can be used as a target protein in the treatment of damp-heat syndrome of RA by Qingre Huoxue Formula. Accordingly， a scientific hypothesis was proposed that Qingre Huoxue Formula may regulate TGF-β signalling pathway mediated by LRG1 to improve “inflammation-bone destruction” of RA， and it was envisioned that the clinical effect of Qingre Huoxue Formula on LRG1 could be confirmed through clinical studies， and the mechanism of action of Qingre Huoxue Formula on the LRG1/TGF-β signalling axis as well as the influence of the expression or non-expression of the LRG1/TGF-β signalling axis on the therapeutic effectiveness of Qingre Huoxue Formula could be clarified through animal experiments.

OBJECTIVE To investigate the effects of astilbin （AST） on myocardial ischemia-reperfusion injury （MIRI） in rats and its potential mechanism. METHODS SD male rats were randomly divided into sham operation group， model group， positive control group （Compound Salvia miltiorrhiza tablets， 240 mg/kg）， AST low-dose and high-dose groups （30， 90 mg/kg）， and high- dose of AST+hypoxia-inducible factor-1α（HIF-1α） inhibitor group （AST 90 mg/kg+2ME2 15 mg/kg）， with 25 rats in each group. Except for sham operation group， MIRI model was induced in other groups， and then given relevant drug or normal saline intragastrically or intraperitoneally， for consecutive 28 d. Serum contents of cardiac troponin I （cTnI） and creatine kinase isoenzyme （CK-MB） were detected； volume ratio of myocardial infarction was measured； the pathological changes of myocardium， the apoptotic rate of myocardial cells and ultrastructure of mitochondria in myocardial tissue were all observed. The contents of tumor necrosis factor α （TNF-α）， interleukin 6 （IL-6） and malondialdehyde （MDA）， the activity of superoxide dismutase （SOD）， the expressions of HIF-1α， adenovirus E1B interacting protein 3 （BNIP3） and myosin-like Bcl-2 interacting protein （Beclin1） were determined in myocardium. The ratio of microtubule-associated protein light chain 3 （LC3） Ⅱ to Ⅰ （LC3 Ⅱ/Ⅰ） in rat myocardium was calculated. RESULTS Compared with model group， no obvious swelling was found in the myocardial tissue of rats in positive control group， AST low-dose and high-dose groups， and the myocardial fibers were arranged regularly； the volume ratio of myocardial infarction， the contents of cTnI， CK-MB， TNF-α， IL-6 and MDA， the apoptotic rate were decreased significantly （P＜0.05）， while SOD activity， protein expressions of HIF-1α， BNIP3 and Beclin1， LC3Ⅱ/Ⅰ were increased significantly （P＜0.05）. HIF-1α inhibitor could significantly weaken the improvement effect of AST on the above indicators in MIRI model rats （P＜0.05）. CONCLUSIONS AST enhances mitochondrial autophagy by activating HIF-1α/BNIP3 signaling pathway， thereby reducing MIRI in rats.

ObjectiveTo explore the underlying molecular mechanism of Xiaochuanning granules in the treatment of bronchial asthma based on the network pharmacology and experimental verification through the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway on ovalbumin （OVA） sensitization-induced bronchial asthma model in rats. MethodThe main active ingredients and targets of Xiaochuanning Granules were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）. The targets related to bronchial asthma were obtained from five disease databases such as GeneCards and Online Mendelian Inheritance in Man （OMIM）. The common targets were screened out through the Venn diagram. STRING was used to construct the protein-protein interaction （PPI） network of "compound-disease"， and Cytoscape 3.8.0 was used to establish a network of key active ingredients of Xiaochuanning granules and core target genes （"ingredient-gene" network）. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were performed through DAVID. The bronchial asthma model was induced by OVA stimulation in rats. Bronchial and lung tissue inflammation was observed by hematoxylin-eosin （HE） staining， and the enrichment analysis results of the network pharmacology were verified by Western blot. ResultIn this experiment， 232 active ingredients and 4 687 related targets of Xiaochuanning granules were screened out， and 233 common targets of Xiaochuanning granules and bronchial asthma were collected， including eosinophil-derived neurotoxin 1 （EDN1）， cyclic AMP response element-binding protein 1 （CREB1）， cyclin-dependent kinase inhibitor 1A （CDKN1A）， epidermal growth factor receptor （EGFR）， mitogen-activated protein kinase 14 （MAPK14）， and Akt1. KEGG pathway analysis revealed 186 related signaling pathways， indicating that the PI3K/Akt signaling pathway presumedly played a key role in the treatment of bronchial asthma by Xiaochuanning granules. The animal experiment showed that Xiaochuanning granules relieved the airway inflammation and smooth muscle hyperplasia in rats and down-regulated the gene expression of PI3K and Akt as compared with the conditions in the model group （P<0.05）. ConclusionXiaochuanning granules have the characteristics of multi-component， multi-target， and multi-pathway synergistic effect in the treatment of asthma. Xiaochuanning granules may exert anti-inflammatory effects by regulating the expression of genes related to the PI3K/Akt signaling pathway. The present study is expected to provide a theoretical basis for follow-up in-depth research on the complex mechanism of Xiaochuanning granules in the treatment of bronchial asthma.

Objective: To evaluate the safety and efficacy of balloon pulmonary angioplasty (BPA) in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH). Methods: A study was conducted on 25 patients consisting of 10 males and 15 females with CTEPH who received BPA treatment from February 2017 to May 2018 in Beijing Chaoyang Hospital, Capital Medical University. The changes of brain natriuretic peptide (BNP), mean pulmonary artery pressure (mPAP), tricuspid annulus systolic plane excursion (TAPSE), six-minute walking test (6WMD), right ventricular basement diameter and WHO cardiac function grading were compared before and after treatment with BPA using paired t test. Results: Twenty-five patients received a total of 50 BPA treatments, and among them, 12 patients received two or more times. The mPAP decreased from (50.4±9.9) mmHg (1 mmHg=0.133 kPa) to (39.9±10.6) mmHg before and after operation, and the difference was statistically significant (t=9.7, P<0.001); BNP decreased from (513.5±357.3) pg/ml to (106.3±137.53) pg/ml, and the difference was significant (t=3.2, P=0.006); TAPSE increased from (16.2±2.8) mm to (18.0±2.4) mm, and the difference was statistically significant (t=-5.7, P=0.002); the right ventricular base diameter decreased from (45.9±6.9) mm to (41.2±7.3) mm, and the difference was statistically significant (t=5.6, P<0.001); 6WMD increased from (371.1±86.8) m to (467.7±76.1) m, with statistical significance (t=-6.4, P<0.001); WHO cardiac function grading was improved from (2.4±0.7) to (1.2±0.4) after surgery, and the difference was statistically significant (t=2.8, P=0.021). Pulmonary artery injury occurred in 3 patients and 2 patients had hemoptysis.The hemoptysis was stopped after arterial embolization. No other complications such as pulmonary edema occurred. Conclusion BPA may improve clinical status and hemodynamics of patients with CTEPH, which offers an alternative approach of treatment in patients with inoperable CTEPH.

Objective: To review the research progress of the role and mechanism of adipokines in intervertebral disc degeneration (IVDD) in recent years. Methods: The domestic and foreign literature related to adipokines in the process of IVDD was extensively reviewed. The types and functions of adipokines, the role and mechanism in the process of IVDD, and the application prospects of intervertebral disc biotherapy were reviewed. Results: As a kind of bioactive substance secreted by adipose tissue, adipokine plays an important role in bone and joint diseases, metabolic diseases, and breast cancer. During IVDD, most adipokines can activate multiple signaling pathways by binding to autoreceptors, cause the proliferation and apoptosis of cells and proinflammatory and anti-inflammatory factors parasecretions in the intervertebral disc, and lead to imbalance of intradiscal metabolism and establishment of the initial inflammatory environment, and finally cause the IVDD. Conclusion: Adipokines, as a biologically active substance with metabolic and immunomodulatory functions, play important roles in the occurrence, development, and biological treatment of IVDD.

Objective: To review the recent progress in the role of thrombospondins (TSPs) in synapse formation in the central nervous system (CNS). Methods: A wide range of domestic and foreign literature on the role of TSPs in the synapse formation of the CNS was reviewed. The role of TSPs in structural features, molecules, and related diseases was reviewed. Results: As an oligosaccharide protein, TSPs play important roles in angiogenesis, inflammation, osteogenesis, cell proliferation, and apoptosis. In the nervous system, they bind to voltage-dependent calcium channels, neuronectin, and other extracellular matrix proteins and cell surface receptors, and participate in and regulate multiple processes such as synapse formation, maturation, and function in the CNS. Conclusion: TSPs as an oligomeric extracellular matrix protein play an important role in the formation of synapses and the repair of synapses after CNS injury.

Objective To explore the protective effect of extracorporeal membrane oxygenation (ECMO) on donor kidneys from non-controllable donation after cardiac death (DCD). Methods A total of 60 non-controllable DCD donors were selected and divided into 3 groups randomly based on the in vivo perfusion time of ECMO: test group 1 received EMCO perfusion for 2 h, test group 2 for 4 h and test group 3 for 6 h, with 20 cases in each group. Corresponding recipients were also divided into 3 groups, with 20 cases in each group. Meanwhile, 20 recipients from donation after brain death (DBD) with stable circulatory function were randomly selected as control group. Incidence of delayed graft function (DGF), primary graft nonfunction (PNF) and acute rejection of the recipients in different groups was compared. The indexes including graft function recovery time, urine volume on day 1 and graft function within 1 year after renal transplantation were compared for the recipients in different groups. And 1-year survival rate of the recipients and grafts after renal transplantation was compared. Results Compared with the control group, various test groups presented no significant differences in the incidence of PNF, DGF and acute rejection (all P>0.05). Compared with the control group, graft function recovery time prolonged significantly in each test group, which presented statistically significant differences (all P<0.05), while the urine volume on day 1 and graft function within 1 year after renal transplantation presented no statistically significant difference in each test group (all P>0.05). The 1-year survival rate of the recipients and grafts after renal transplantation was 100％ in various test groups and control group, which presented no statistically significant difference (all P>0.05). Conclusions ECMO can protect donor kidneys effectively through assisting the circulatory or respiratory function of non-controllable DCD, and improve their utilization rate.
