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.

Objective:To investigate the clinical characteristics and treatment strategies of patients with connective tissue disease (CTD) related lymphatic duct obstruction.Methods:The clinical data, laboratory tests results, imaging data, and treatment of CTD patients associated with lymphatic vessel obstruction were retrospectively collected from January 2008 to December 2020 at Beijing Shijitan Hospital. Lymphatic duct obstruction was confirmed by thoracic duct ultrasound or thoracic duct MRI or lymphoscintigraphy or direct lymphangiography. SLE and RA patients were matched with gender and age in a 1∶2 ratio, and SLE and RA patients without lymphatic reflux disorder admitted at the same time were randomly selected as the control group. When comparing the data between the two groups, t-test or rank sum test was used to test continuous variables, and chi-square test or Fisher′s exact probability method was used to test categorical variables. Results:Forty-four patients with CTD complicated with thoracic duct obstruction were included, with a male-to-female ratio of 7∶37, including 14 cases of rheumatoid arthritis (RA), 21 cases of systemic lupus erythematosus (SLE), 8 cases of primary Sjogren's syndrome (pSS), and 1 case of systemic sclerosis (SSc). The onset age of CTD ranged from 14 to 68 years, the mean age was (37±15) years and the median duration of CTD was 66 (range 1~480) months. The median age at the onset of lymphatic duct obstruction such as limb edema or thoracoabdominal effusion was (42±17) years, and the median duration of lymphatic duct obstruction symptoms was 12 (range 3~480) months. 59%(26/44) of patients were diagnosed with CTD followed by the diagnosis of thoracic duct obstruction, and 41%(18/44) of patients had lymphatic duct obstruction symptoms as the initial presentation of CTD. Thoracic duct-related imaging was performed in 44 patients and showed thoracic duct obstruction (64%, 28/44), thoracic duct malformation or variation (36%, 16/44), limb lymphatic reflux disorder (34%, 15/44), and small bowel lymphatic duct dilatation or intestinal protein loss (18%, 8/44), respectively. Compared with the control group, among these patients, patients with RA complicated with lymphatic involvement had a younger onset age [(34±14)years old vs. (44±13)years old, t=-2.15, P=0.037)] and longer RA course [(17±11)months vs. (7±7)months, t=3.38, P=0.002] and presented with limb swelling (12/14). While compared with the control group, SLE patients complicated with lymphatic duct obstruction presented with celiac multi-plasmatic effusion (20/21), more patients presented with multiple serous cavity effusion [95%(20/21) vs. 62%(25/42), χ2=7.63, P=0.006], but the prevalence of lupus nephritis [(60%(12/21) vs. 86%(36/42), χ2=4.87, P=0.027] and lupus encephalopathy [0%(0/21) vs. 16.7%(17/42), χ2=6.11, P=0.013] was lower. 27% (12/44) of patients improved with aggressive glucocorticoids combined with immunosuppressive therapy, 54%(24/44) of patients were performed with lymphatic duct reconstruction surgery on top of medical treatment, 5 patients were lost of follow-up, and 2 patients deceased. Conclusion:CTD patients may develop lymphatic duct obstruction during the disease course, while lymphatic duct obstruction can also be the initial presentation of CTD. Rheumatologists and surgeons should be alert to this rare situation. Young women with refractory polyserositis or lymphedema should be examined for the possibility of combined CTD. Lymphatic duct obstruction may be associated with long-term chronic inflammation in CTD. Glucocorticoids combined with immunosuppressive agents and surgery can be used to treat lymphatic duct obstruction in patients with CTD.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

The study aimed to examine the effects of virtual reality (VR) technology-based phase I cardiac rehabilitation (CR) program in elderly coronary heart disease (CHD) patients after percutaneous coronary intervention (PCI). Thirty-six cases of elderly CHD patients who underwent PCI in the First Affiliated Hospital of Chongqing Medical University from June 2022 to April 2023 were recruited by convenience sampling method. The patients were randomly assigned by means of random digital table method to two study groups: control group (n = 18), which received conventional nursing intervention after PCI, and experimental group (n = 18), which received a combined program of conventional nursing intervention together with CR program based on VR technology. The 6 min walk test (6MWT), Simple Physical Performance Battery (SPPB), SF-36 scale, Hospital Anxiety and Depression Scale (HADS) and Impact of Events Scale-Revised (IES-R) were tested before and after rehabilitation. Moreover, the incidence of major adverse cardiovascular events (MACE) was recorded at 3 months after PCI. After VR-based CR, the 6MWT distance and SPPB scores of patients in the experimental group were higher than those in control group (P < 0.05). The HADS scores and IES-R scores of the patients in the experimental group were lower than those in control group (P < 0.01), and the difference in SF-36 scale scores was not statistically significant between two groups (P > 0.05). The incidence of MACE was not significantly different at 3 months after PCI (P > 0.05). These results suggest that VR-based phase I CR program mitigates the degree of PCI postoperative stress, anxiety, and depression in elderly CHD patients, however, enhances the resistance to fatigue and does not increase the risk of adverse cardiac events, suggesting it is a safe intervention.

italic>α-Conotoxin ArIB[V11L,V16D] is currently the most optimal selective inhibitor of α7 nicotinic acetylcholine receptor (nAChR) known. In order to explore chemical modification methods and enrich its application in targeting nAChR, this study utilized the linker to covalently connect camptothecin and 7-amino-4-methylcoumarin to the [2,4] disulfide bond of ArIB[V11L,V16D]. Therefore, two peptide-drug conjugates (PDCs), ArIB[V11L,V16D]-5 and ArIB[V11L,V16D]-6, and one fluorescent-labeled peptide, ArIB[V11L,V16D]-7 were constructed. Cytotoxicity evaluation showed that the IC₅₀ values against non-small cell lung cancer cell line A549 of the two PDCs were respectively 1.3 and 4.1 times of camptothecin, indicating slight reduction in activity at the cellular level which was related to the linker structure. Fluorescence spectrum scanning revealed that the excitation and emission wavelength of the fluorescent-labeled peptide were 340 nm and 403 nm respectively, and the fluorescence features of 7-amino-4-methylcoumarin as a marker were retained without fluorescence quenching. This modification strategy laid a solid foundation for the further application of α-conotoxin ArIB[V11L,V16D] in PDCs and fluorescent probes.

This paper aimed to study the effect of Dalbergia cochinchinensis heartwood on plasma endogenous metabolites in rats with ligation of the left anterior descending coronary artery, and to analyze the mechanism of D. cochinchinensis heartwood in improving acute myocardial ischemic injury. The stability and consistency of the components in the D. cochinchinensis heartwood were verified by the establishment of fingerprint, and 30 male SD rats were randomly divided into a sham group, a model group, and a D. cochinchinensis heartwood(6 g·kg~(-1)) group, with 10 rats in each group. The sham group only opened the chest without ligation, while the other groups established the model of ligation. Ten days after administration, the hearts were taken for hematoxylin-eosin(HE) staining, and the content of heart injury indexes in the plasma creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH), energy metabolism-related index glucose(Glu) content, and vascular endothelial function index nitric oxide(NO) was determined. The endogenous metabolites were detected by ultra-high-performance liquid chromatography-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS). The results showed that the D. cochinchinensis heartwood reduced the content of CK-MB and LDH in the plasma of rats to relieve myocardial injury, reduced the content of Glu in the plasma, improved myocardial energy metabolism, increased the content of NO, cured the vascular endothelial injury, and promoted vasodilation. D. cochinchinensis heartwood improved the increase of intercellular space, myocardial inflammatory cell infiltration, and myofilament rupture caused by ligation of the left anterior descending coronary artery. The metabolomic study showed that the content of 26 metabolites in the plasma of rats in the model group increased significantly, while the content of 27 metabolites decreased significantly. Twenty metabolites were significantly adjusted after the administration of D. cochinchinensis heartwood. D. cochinchinensis heartwood can significantly adjust the metabolic abnormality in rats with ligation of the left anterior descending coronary artery, and its mechanism may be related to the regulation of cardiac energy metabolism, NO production, and inflammation. The results provide a corresponding basis for further explaining the effect of D. cochinchinensis on the acute myocardial injury.

OBJECTIVES: To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS). METHODS: A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis. RESULTS: Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment. CONCLUSIONS Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.
