Acute myocardial infarction and acute upper gastrointestinal bleeding are both critical internal medicine conditions. The incidence of acute upper gastrointestinal bleeding in patients with acute myocardial infarction ranges from 5.31% to 8.90%, with a mortality rate as high as 20.50% to 35.70%. The pathogenesis may be related to the use of antiplatelet and anticoagulant drugs, as well as stress-induced injury. In treatment, the contradiction between antiplatelet/anticoagulation therapy and bleeding has made this disease a significant challenge in modern medicine. Therefore, re-exploring the etiology, pathogenesis, treatment principles, and methods of traditional Chinese medicine(TCM) for acute myocardial infarction and acute upper gastrointestinal bleeding is of great clinical importance. The research team has been working year-round in the coronary care unit(CCU), managing a large number of such severe patients. By revisiting classic texts and delving into the foundational theories of TCM and historical medical literature, it has been found that this disease falls under the category of "distant blood" in the Synopsis of the Golden Chamber. In terms of etiology, it is primarily associated with weakness of healthy Qi and damage caused by drug toxicity. In terms of pathogenesis, in the acute stage, it mainly manifests as insufficient spleen Yang, deficiency of spleen Qi, and failure of the spleen to control blood. In the remission stage, it is characterized by deficiency of both heart Qi and spleen blood. For treatment, during the acute stage, Huangtu Decoction is used to warm Yang and restrain blood, while in the remission stage, Guipi Decoction is administered to tonify Qi and nourish blood. During the treatment process, for patients with acute myocardial infarction complicated with acute upper gastrointestinal bleeding, it is crucial to flexibly apply the treatment principles of "Nil per os" in western medicine and "where there is stomach Qi, there is life; where there is no stomach Qi, there is death" in TCM. Early intervention with Huangtu Decoction can also prevent bleeding, with large doses being key to achieving hemostasis. It is important to address the pathogenesis of heat syndrome in addition to the core pathogenesis of Yang deficiency bleeding and to emphasize the follow-up treatment with Guipi Decoction for a successful outcome.

Objective:To investigate the clinical efficacy of stamp skin grafting combined with vacuum sealing drainage in the treatment of diabetic foot ulcers.Methods:A prospective study was conducted involving 80 patients with diabetic foot ulcers admitted to Lishui Central Hospital from January 2020 to December 2022. The patients were divided into an observation group and a control group, with 40 patients in each group, using a random number table method. The control group received treatment with vacuum-sealing drainage technology, while the observation group was treated with stamp skin grafting combined with vacuum sealing drainage. The two groups were compared based on several perioperative indicators, including wound healing time, length of hospital stay, number of dressing changes, and progress of granulation tissue growth. Pain levels were assessed using the Visual Analog Scale. Additionally, dorsalis pedis blood flow dynamics were evaluated, focusing on the diameter of the dorsalis pedis artery and arterial blood flow velocity. Foot function was assessed using the Maryland Foot Function Scale. The occurrence of postoperative complications was recorded.Results:The wound healing time and length of hospital stay in the observation group were (21.54 ± 5.32) days and (27.08 ± 5.97) days, respectively, which were significantly shorter than those in the control group [(26.69 ± 5.66) days, (31.49 ± 6.80) days, t = 4.19, 3.08, both P < 0.05]. The number of dressing changes in the observation group was (5.11 ± 1.14), which was significantly fewer than that in the control group [(8.07 ± 1.59), t = 9.56, P < 0.001]. The progress of granulation tissue growth in the observation group [(3.12 ± 0.64) mm] was faster that in the control group [(2.09 ± 0.48) mm, t = 8.14, P < 0.001]. At 1, 2, and 3 months post-surgery, the Visual Analog Scale scores for the observation group were (3.52 ± 0.65), (2.33 ± 0.42), and (1.40 ± 0.26), respectively, which were significantly lower than those in the control group [(3.96 ± 0.71), (2.74 ± 0.44), (1.78 ± 0.34), t = 2.89, 4.26, 5.615, all P < 0.05). At 3 months post-surgery, the diameter of the dorsalis pedis artery and arterial blood flow velocity in the observation group were (2.64 ± 0.44) mm and (36.42 ± 6.28) cm/s, respectively, which were greater than those in control group [(2.18 ± 0.41) mm, (30.97 ± 5.33) cm/s, t = 4.83, 4.18, both P < 0.001]. At 3 months post-surgery, the scores for pain, foot function, appearance, and range of motion in the observation group were (39.28 ± 6.70), (48.10 ± 7.22), (7.94 ± 1.54), and (12.15 ± 2.35), respectively, which were significantly higher than those in the control group [(33.46 ± 6.89), (43.08 ± 6.68), (5.38 ± 1.06), and (10.69 ± 2.16), t = 3.83, 3.22, 8.66, 2.89, all P < 0.05]. There was no statistically significant difference in the overall incidence of postoperative complications, including skin flap necrosis/dislocation, hematoma accumulation, infection, and ulcer recurrence, between the two groups ( P > 0.05). Conclusions:Stamp skin grafting combined with vacuum sealing drainage can significantly accelerate wound healing in patients with diabetic foot ulcers, reduce postoperative pain, improve dorsalis pedis blood flow dynamics, enhance foot function, and demonstrate good safety.

The prevalence of cardiovascular diseases in China has shown a rising trend. With the patient number of about 8.9 million, heart failure has brought a heavy burden to public health and wellness. Despite the modern medical research progress in the pathogenesis and clinical treatment of heart failure, the patients with heart failure still suffer from recurrent episodes of dyspnea(requiring repeated hospital admissions), diuretic resistance, elevated creatinine levels due to prolonged diuretic use, and poor prognosis, among other major clinical and scientific issues. In traditional Chinese medicine(TCM), heart failure belongs to the category of "heart water". The research team has found that because of the changes in the modern disease spectrum, the differences between ancient and modern physical constitutions, and the use of anti-heart failure drugs in modern medicine, the pathological process of heart failure has been altered, and the symptoms of some patients have become unobvious. As a result, the etiology and pathogenesis of heart failure have undergone major changes. The disease causes include external pathogen attack, emotional disorders, excessive labor injury, medication-induced damage, dietary disorders, water-dampness stagnation, and endowment insufficiency. These causes are closely related to the infection aggravation-induced heart failure, cardiac and psychological diseases, and heart volume overload in modern medicine. The pathogeneses of heart failure include edema due to Yang deficiency and water retention turning into heat in the acute stage and liver depression and Qi stagnation, heart Qi deficiency, kidney Yang deficiency, Qi deficiency in lung and spleen, phlegm and water retention, and internal obstruction due to blood stasis in the remission stage. The corresponding treatment strategies were recommended as follows: Zhenwu Decoction for edema due to Yang deficiency, Mufangji Decoction for water retention turning into heat, Chaihu Longgu Muli Decoction for liver depression and Qi stagnation, Guizhi Decoction for heart Qi insufficiency, Shenqi Pills and Yougui Pills for kidney Yang deficiency, Yupingfeng Powder, Lizhong Decoction, Buzhong Yiqi Decoction, and Guipi Decoction for Qi deficiency in lung and spleen, Fangji Huangqi Decoction, Wuling Powder, Linggui Zhugan Decoction, and Tingli Dazao Xiefei Decoction for internal obstruction due to phlegm and water retention, Guizhi Fuling Pills and Danggui Shaoyao Powder for internal obstruction due to blood stasis. The clinical treatment should follow the principle of considering both pathogenesis and pathology as well as both medicine nature and mechanism. The TCM concept of secondary prevention with TCM formulas for replenishing deficiency should be adopted. The treatment based on the principle and concept above will improve the patients' quality of life, reduce the number of hospital admissions, ameliorate diuretic resistance, and improve the clinical outcomes.

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.

In order to understand the prevalence and genetic variation of H9N2 subtype avian influ-enza virus in Shandong,a total 492 tracheal and lung tissue samples collected from chicken farms with respiratory symptoms in partial areas in Shandong were detected by H9 subtype AIV real-time RT-PCR,and the positive samples were inoculated with chicken embryos for two generations.Whole genome sequences of the positive strains by applying Illumina Miaseq platform,and genetic evolution and mutation at positions associating with viral pathogenicity and transmissibility were analyzed.The results showed that there were 72 samples were positive for H9 subtype AIV among the 492 samples,with a positive rate of 14.63%.Thirty-four strains of H9 subtype AIV were ob-tained from the positive samples after passing through chicken embryo,meanwhile,the 34 isolates were all H9N2 subtype AIV by whole genome sequencing analysis.By analyzing the evolutionary tree of HA and NA genes,HA and NA genes of the 34 H9N2 AIV strains belonged to Y280-like branch and F/98-like branch,respectively.Meanwhile,based on above branches,there were obvious time node subbranch,which one was"isolates before 2013",another one was"isolates after 2013".The HA cleavage sites of thirty-four H9N2 strains were all 325PSRSSR↓GLF333,which met the se-quence characteristics of the lowly pathogenic avian influenza virus,and the HA receptor binding site 226 amino acid was leucine,which had the characteristics of blinding to a-2,6 mammalian sialic acid receptors.Among the internal amino acid sites that are key to mammalian adaptation,all strains had an I368V mutation in the PB1 gene that enhanced viral transmissibility in mammals and the PB2 genes of some strains were mutated to enhance the mammalian adaptation of I292 V and A588 V.The above results illustrated that the H9N2 subtype AIV gene segments in Shandong have different degrees of recombination and gene variation,so it is necessary to strengthen the monito-ring of virus variation.
