[Objective] To expound the diagnosis and treatment of chronic heart failure by tranditional Chinese and western medicine, to make the syndrome differentiation and treatment more accurate and the efficacy better. [Method] The progression of chronic heart failure can be divided into four stages, to combine the tranditional Chinese and western medicine to use the traditional Chinese theory to treat the four stages. [Result] Pre-heart failure and pre-clinical heart failure most belong to Qi deficiency of heart and lung syndrome, deficiencies of Qi and Yin syndrome; Clinical heart failure belongs to Qi deficiency and blood stasis syndrome, turbid-phlegm and water-rheum collecting internally syndrome; refractory end-stage heart failure belongs to heart-kidney Yang deficiency and water flooding syndrome, spleen-kidney Yang deficiency and endogenous turbid-phlegm syndrome, even depletion of Yin and Yang syndrome.[Conclusion] The pattern of diagnosis and treatment of combind tranditional Chinese and western medicine is the result of the development of modern medicine which contributes to the diagnosis of tradition Chinese medicine. This paper expounds the syndrome differentiation and treatment based on the western medical staging to make the syndrome differentiation and treatment accuracy and the curative effect better.

AIM:Todeterminetheeffectofsalviaextractonangiogenesisofthemyocardiumintheratswith myocardial infarction (MI) and to analyze its possible mechanism .METHODS: Left coronary artery of Sprague-Dawley rats was ligated to establish a MI model .The rats were randomly divided into MI model group , 3 different dose groups of salvia (10, 20 and 40 mg? kg-1? d-1), and sham operation group.Each group consisted of 8 rats.The rats in all treat-ment groups were orally administered with the salvia extract , and the rats in MI group and sham operation group were fed with the same volume of saline .The rats were sacrificed 4 weeks later .The hemodynamic changes of the rats were deter-mined , and the segmental heart samples were used for morphological observation by hematoxylin and eosin staining , Masson staining, or electron microscopic analysis.The expression of vascular endothelial growth factor (VEGF) and cluster of dif-ferentiation 34 ( CD34 ) was analyzed according to immunohistochemistry .RESULTS: Compared with sham operation group, the morphological changes of the myocardium in MI group were disordered , part of myocardial cell outline disap-peared , and obvious fibrosis in the necrosis myocardial tissue and fuzzy or disappearing microvascular ultrastructure were al -so observed .Compared with MI group , the number of new microvessels in all the treatment groups increased obviously , and the morphological changes of the endothelial cells were relatively complete according to electron microscopy .Compared with sham operation group , the protein expression of VEGF and CD 34 in the cytoplasm of the myocardial tissues in MI group in-creased only a little .Compared with MI group , the protein expression of VEGF and CD 34 in the cytoplasm of the myocardi-al tissues in all treatment groups increased significantly ( P<0.01 ) .CONCLUSION: Salvia extract obviously promotes angiogenesis of the myocardial tissues in the rats after myocardial infarction .

Objective To explore the effect of astragalus extracts on adherence, migration, cell viability, microvascular formation, and eNOS expression in bone marrow-derived endothelial progenitor cells (EPCs) of rats. Methods EPCs were cultured, isolated and identified in vitro and divided into four groups: low titer group (10-4 g/L of astragalus extracts), middle titer group (10-3 g/L of astragalus extracts), high titer group (10-2 g/L of astragalus extracts) and control group. The effects of astragalus extract on adhesion, migration or microvascular formation were observed under the inverted microscope and com?pared between all groups;Cell viability was detected by MTT assay;mRNA transcription and protein expression levels of en?dothelial nitric oxide synthase (eNOS) in EPCs were detected by reverse transcription PCR (RT-PCR) and Western blot re?spectively. Results Compared with the control group, cell adhesion, migration and microvascular formation of EPCs all en?hanced with addition of astragalus extracts in a dose dependent manner (F=15.256, 13.633, 97.549 respectively, and P <0.05 in all cases); Cell vitality of EPCs increased with administration of astragalus extracts in a time and dose dependant manner. (F=9.755 for time and F=10.18 for dose). mRNA transcription and protein expression of eNOS in EPCs were up-reg?ulated with addition of astragalus extracts in a dose dependent manner (F=56.356 and 77.125 respectively, and P<0.05 in both cases). Conclusion Astragalus extracts play important role in angiogenesis in EPCs probably through up-regulating expressions of eNOS.

Aim To explore the effect of protein kinase D1 (PKD1 )on adherence,migration,proliferation, microvascular formation,and eNOS expression in bone marrow-derived endothelial progenitor cells(EPCs)of rats.Method The EPCs were isolated from bone marrow of rats,cultured and detected,the effects of PKD1 and its specific blocking agent CID755673 on adhesion,migration,proliferation,or microvascular formation were observed,as well as mRNA and protein expression of endothelial nitric oxide synthase (eNOS ) in EPCs.Results PKD1 significantly promoted adhe-sion,migration,proliferation and microvascular forma-tion of EPCs,and upregulated the mRNA and protein expression of eNOS in EPCs,according to the cell cul-ture experiments of EPCs in vitro.Conclusion PKD1 has the role of angiogenesis through regulation of EPCs,which might be dependent on eNOS.

Development of thoracolumbar vertebra (TLV) and rib primordium (RP) is a common evolutionary feature across vertebrates, although whole-organism analysis of the expression dynamics of TLV- and RP-related genes has been lacking. Here, we investigated the single-cell transcriptome landscape of thoracic vertebra (TV), lumbar vertebra (LV), and RP cells from a pig embryo at 27 days post-fertilization (dpf) and identified six cell types with distinct gene expression signatures. In-depth dissection of the gene expression dynamics and RNA velocity revealed a coupled process of osteogenesis and angiogenesis during TLV and RP development. Further analysis of cell type-specific and strand-specific expression uncovered the extremely high level of HOXA10 3'-UTR sequence specific to osteoblasts of LV cells, which may function as anti-HOXA10-antisense by counteracting the HOXA10-antisense effect to determine TLV transition. Thus, this work provides a valuable resource for understanding embryonic osteogenesis and angiogenesis underlying vertebrate TLV and RP development at the cell type-specific resolution, which serves as a comprehensive view on the transcriptional profile of animal embryo development.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
