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 incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To study the application of conicity index (CI),body mass index (BMI),waist-to-hip ratio (WHR) and body fat ratio (BFR) in abdominal obesity in maintenance hemodialysis (MHD) patients. Methods The patients who received dialysis treatment in the hemodialysis center of the Third Affiliated Hospital of Chongqing Medical University from September to December 2023 were selected by fixed-point cluster sampling,and the age,dialysis age,height,weight,biochemical examination indexes and other information of the study subjects were collected,and the body composition analysis was performed using InBody S10 and the visceral fat area was used as the basis for the determination of abdominal obesity. The applications of body mass index,body fat ratio,waist-to-hip ratio and conicity index in predicting abdominal obesity in MHD patients were compared. Results A total of 151 patients were enrolled,including 65 patients with abdominal obesity MHD and 86 patients with non-abdominal obesity MHD. The results showed that there were significant differences in gender,weight,BMI,visceral fat area,body fat ratio,waist-to-hip ratio,conicity index and the prevalence of diabetes between patients with abdominal obesity and non-abdominal obesity (all P<0.05). The consistency test results showed that the consistency between using BMI,body fat percentage,and waist hip ratio to determine abdominal obesity with visceral fat area method was weak,with the conicity index Kappa coefficient having the largest value (P<0.05).The analysis of receiver operating characteristic (ROC) curve showed that the area under the ROC curve of conicity index was the highest,0.765,indicating the highest diagnostic efficacy (P<0.05) in MHD patients. Conclusion Conicity index,body mass index,waist-to-hip ratio and body fat ratio can be used in the diagnosis of abdominal obesity in MHD patients,among which the conicity index is more effective.

This study aims to investigate the pathogenesis of chronic heart failure based on ferroptosis-mediated oxidative stress and predict the targets of Shenfu Injection in treating chronic heart failure. A rat model of chronic heart failure was established by the isoproterenol induction method. According to the random number table method, the modeled rats were assigned into three groups: a model group, a Shenfu Injection group, and a ferrostatin-1(ferroptosis inhibitor) group. In addition, a normal group was designed. After 15 days of intervention, the cardiac mass index and left ventricular mass index were determined. Echocardiography was employed to eva-luate the cardiac function. Hematoxylin-eosin staining and Masson staining were employed to reveal the pathological changes and fibrosis of the heart, and Prussian blue staining to detect the aggregation of iron ions in the myocardial tissue. Transmission electron microscopy was employed to observe the mitochondrion ultrastructure in the myocardial tissue. Colorimetry was adopted to measure the levels of iron metabolism, lipid peroxidation, and antioxidant indicators. Flow cytometry was employed to measure the content of lipid-reactive oxygen species(ROS) and the fluorescence intensity of ROS. Western blot and RT-qPCR were employed to determine the protein and mRNA levels, respectively, of ferroptosis-related factors in the myocardial tissue. The results showed that the rats in the model group had reduced cardiac function, elevated levels of total iron and Fe~(2+), lowered level of glutathione(GSH), increased malondialdehyde(MDA), decreased superoxide dismutase(SOD) and glutathione peroxidase(GSH-Px), and rising levels of ROS and lipid-ROS. In addition, the model group showed fibrous tissue hyperplasia with inflammatory cell infiltration and myocardial fibrosis, iron ion aggregation, and characteristic mitochondrial changes specific for iron death. Moreover, the model group showcased upregulated protein and mRNA levels of p53 and COX2 and downregulated protein and mRNA levels of GPX4, FTH1, SLC7A11, and Nrf2 in the myocardial tissue. The intervention with Shenfu Injection significantly improved the cardiac function, recovered the iron metabolism, lipid peroxidation, and antioxidant indicators, decreased iron deposition, improved mitochondrial structure and function, and alleviated inflammatory cell infiltration and fibrosis. Furthermore, Shenfu Injection downregulated the mRNA and protein levels of p53 and COX2 and upregulated the mRNA and protein levels of GPX4, FTH1, SLC7A11, and Nrf2 in the myocardial tissue. Shenfu Injection can improve the cardiac function by regulating iron metabolism, inhibiting ferroptosis, and reducing oxidative stress injury.

This study aimed to investigate the mechanism and target sites of Shenfu Injection in the intervention of chronic heart fai-lure based on the PI3K/Akt/mTOR autophagy signaling pathway. The chronic heart failure model was induced in rats by subcutaneous injection of isoproterenol. The model rats were randomly divided into model group, Shenfu Injection group, and 3-methyladenine autophagy inhibitor(3-MA) group. A normal group was also set up. After 15 days of administration, cardiac function indexes of the rats were detected by echocardiography. The serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) levels were measured using the ELISA. HE and Masson staining was performed to observe the morphological changes in myocardial tissues, and electron microscopy was used to observe the autophagosomes in myocardial tissues. Western blot was conducted to measure the changes in autophagy-related proteins(LC3 Ⅱ/Ⅰ and p62), PI3K, Akt, mTOR, and phosphorylation levels. The results showed that compared with normal group, model group in rats led to reduced cardiac function, significant activation of cardiac autophagy, increased fibrotic lesions in myocardial tissues, structural disorder of the myocardium, increased autophagosomes, and cytoplasmic vacuolization. Compared with model group, Shenfu Injection group in rats led to cardiac function significantly improved, myocardial fibrosis decreased, and the number of autophagosomes and cytoplasmic vacuolization decreased. The phosphorylation levels of PI3K, Akt, and mTOR were significantly increased(P<0.01). In the 3-MA group, autophagy was inhibited through the activation of the PI3K/Akt/mTOR signaling pathway, resulting in improved cardiac function, reduced myocardial fibrosis, and no significant cytoplasmic vacuolization. The findings suggest that Shenfu Injection can activate the PI3K/Akt/mTOR signaling pathway and inhibit autophagy, thereby improving cardiac function.

This study investigated the mechanisms and targets of Shenfu Injection in the intervention in chronic heart failure(CHF) through the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/caspase-1 signaling pathway. A CHF model was induced in rats by subcutaneous injection of isoproterenol. Model rats were randomly divided into a model group, a Shenfu Injection group, and a MCC950(NLRP3 inhibitor) group, and a blank group was also set up as a control. After 15 days of treatment, echocardiography was performed to measure cardiac function parameters [left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS)]. Enzyme-linked immunosorbent assay(ELISA) was used to measure serum levels of N-terminal pro-brain natriuretic peptide(NT-proBNP), interleukin(IL)-1β, and IL-18. Hematoxylin-eosin(HE) and Masson staining were used to observe morphological changes in myocardial tissues, and Western blot was used to measure the expression levels of NLRP3/caspase-1 pathway-related proteins [NLRP3, caspase-1, apoptosis-associated speck-like protein containing a CARD(ASC), gasdermin D(GSDMD), IL-1β, and IL-18]. The study found that isoproterenol-induced CHF in rats resulted in decreased cardiac function, worsened myocardial fibrosis, increased expression levels of NLRP3, ASC, caspase-1, GSDMD-N, IL-1β, and IL-18 in myocardial tissues, elevated serum inflammatory factors, and induced myocardial cell pyroptosis. Following Shenfu Injection intervention, the Shenfu Injection group showed significantly improved LVEF and LVFS, a significant decrease in NT-proBNP, a marked downregulation of NLRP3, ASC, caspase-1, GSDMD-N, IL-1β, and IL-18 protein expression levels, reduced serum inflammatory factors IL-1β and IL-18 expression in CHF rats, and a decrease in the rate of TUNEL-positive cells. Shenfu Injection can significantly improve cardiac function in CHF, inhibit myocardial fibrosis, and alleviate the progression of myocardial cell pyroptosis through the inhibition of the NLRP3/caspase-1 pathway.

OBJECTIVE: To compare the biomechanical differences among the five internal fixation modes in treatment of Day type Ⅱ crescent fracture dislocation of pelvis (CFDP), and find an internal fixation mode which was the most consistent with mechanical principles. METHODS: Based on the pelvic CT data of a healthy adult male volunteer, a Day type Ⅱ CFDP finite element model was established by using Mimics 17.0, ANSYS 12.0-ICEM, Abaqus 2020, and SolidWorks 2012 softwares. After verifying the validity of the finite element model by comparing the anatomical parameters with the three-dimensional reconstruction model and the mechanical validity verification, the fracture and dislocated joint of models were fixed with S ₁ sacroiliac screw combined with 1 LC-Ⅱ screw (S ₁+LC-Ⅱ group), S ₁ sacroiliac screw combined with 2 LC-Ⅱ screws (S ₁+2LC-Ⅱ group), S ₁ sacroiliac screw combined with 2 posterior iliac screws (S ₁+2PIS group), S ₁ and S ₂ sacroiliac screws combined with 1 LC-Ⅱ screw (S ₁+S ₂+LC-Ⅱ group), S ₂-alar-iliac (S ₂AI) screw combined with 1 LC-Ⅱ screw (S ₂AI+LC-Ⅱ group), respectively. After each internal fixation model was loaded with a force of 600 N in the standing position, the maximum displacement of the crescent fracture fragments, the maximum stress of the internal fixation (the maximum stress of the screw at the ilium fracture and the maximum stress of the screw at the sacroiliac joint), sacroiliac joint displacement, and bone stress distribution around internal fixation were observed in 5 groups. RESULTS: The finite element model in this study has been verified to be effective. After loading 600 N stress, there was a certain displacement of the crescent fracture of pelvis in each internal fixation model, among which the S ₁+LC-Ⅱ group was the largest, the S ₁+2LC-Ⅱ group and the S ₁+2PIS group were the smallest. The maximum stress of the internal fixation mainly concentrated at the sacroiliac joint and the fracture line of crescent fracture. The maximum stress of the screw at the sacroiliac joint was the largest in the S ₁+LC-Ⅱ group and the smallest in the S ₂AI+LC-Ⅱ group. The maximum stress of the screw at the ilium fracture was the largest in the S ₁+2PIS group and the smallest in the S ₁+2LC-Ⅱ group. The displacement of the sacroiliac joint was the largest in the S ₁+LC-Ⅱ group and the smallest in the S ₁+S ₂+LC-Ⅱ group. In each internal fixation model, the maximum stress around the sacroiliac screws concentrated on the contact surface between the screw and the cortical bone, the maximum stress around the screws at the iliac bone concentrated on the cancellous bone of the fracture line, and the maximum stress around the S ₂AI screw concentrated on the cancellous bone on the iliac side. The maximum bone stress around the screws at the sacroiliac joint was the largest in the S ₁+LC-Ⅱ group and the smallest in the S ₂AI+LC-Ⅱ group. The maximum bone stress around the screws at the ilium was the largest in the S ₁+2PIS group and the smallest in the S ₁+LC-Ⅱ group. CONCLUSION For the treatment of Day type Ⅱ CFDP, it is recommended to choose S ₁ sacroiliac screw combined with 1 LC-Ⅱ screw for internal fixation, which can achieve a firm fixation effect without increasing the number of screws.
