ObjectiveTo investigate the correlation of the serum levels of aminotransferases and their ratios with liver inflammation activity in pediatric chronic hepatitis B （pCHB） patients， and to provide a basis for selecting the dominant population for treatment. MethodsThis study was conducted among 1 267 pCHB patients who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2010 to August 2022 and these patients did not receive antiviral therapy. The patients were analyzed in terms of demographic features， blood routine， blood biochemistry， HBV serological markers， and liver biopsy data. According to liver inflammation activity based on liver biopsy， the patients were divided into no or mild inflammation activity （G0‍ ‍—‍ ‍G1） group and significant inflammation activity （G2‍ ‍—‍ ‍G4） group. The serum levels of aminotransferases and their ratios were compared between groups， and their correlation with liver inflammation activity in pCHB patients was analyzed. Additionally， the patients were stratified by the age， and the relationship between serum aminotransferase levels and liver inflammation activity was analyzed in each age group. For comparison of continuous data between two groups， the independent samples t-test was used when the data were normally distributed， while the Mann-Whitney U test was used when the data were not normally distributed； the chi-square test was employed for comparison of categorical data between two groups. A Spearman’s correlation analysis was performed for correlation assessment. ResultsAmong the 1 267 pCHB patients， there were 468 （36.9%） in the G0‍ ‍—‍ ‍G1 group and 799 （63.1%） in the G2‍ ‍—‍ ‍G4 group， and there were significant differences between the two groups in the levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， AST/ALT ratio， gamma-glutamyl transpeptidase （GGT）， total bilirubin， direct bilirubin， HBeAg quantification， low-density lipoprotein， and platelet count （PLT） （all P<0.05）. The correlation analysis showed that liver inflammation activity was negatively correlated with PLT and low-density lipoprotein （both P<0.05） and was positively correlated with GGT， total bilirubin， direct bilirubin， and HBeAg titer （all P<0.05）， while it was not significantly correlated with ALT， AST， and AST/ALT ratio （all P>0.05）. In the 0‍ ‍—‍ ‍12 years group， the 13‍ ‍—‍ ‍18 years male group， and the 13‍ ‍—‍ ‍18 years female group， liver inflammation activity aggravated with the increases in the serum levels of ALT and AST， and there were significant differences between groups （all P<0.05）. In the 0‍ ‍—‍ ‍12 years group， there was a significant difference in significant liver inflammation activity between the AST/ALT ratio >1 group and the AST/ALT ratio ≤1 group （P<0.001）. Among the 1 267 patients， 447 （35.28%） had an ALT level of <2×upper limit of normal （ULN）， among whom 196 （43.85%） had G≥2 liver inflammation， accounting for 15.47% of all children enrolled. ConclusionLiver inflammation activity is not significantly correlated with ALT， AST， and AST/ALT ratio in pCHB patients， suggesting that the serum levels of aminotransferases cannot truly reflect liver inflammation activity in pCHB patients with an aminotransferase level of <2×ULN. In clinical practice， liver biopsy should be performed for children with an aminotransferase level of <2×ULN to clarify whether antiviral therapy should be performed.

Acute carbon monoxide poisoning (ACMP) is one of the most common gas poisonings in the emergency department, with tens of thousands of people seeking medical attention for carbon monoxide (CO) poisoning each year. The severity of poisoning is dependent upon environmental and human factors, with hypoxia and oxidative stress being important mechanisms of cardiac toxicity induced by CO. Myocardial involvement is common in moderate to severe ACMP, including myocardial injury, myocardial infarction, arrhythmia, and sudden death, which are associated with a high risk of death. Ferroptosis is a cell death mechanism caused by iron-dependent lipid peroxidation (LPO), although ferroptosis has been shown to play a critical role in various cardiovascular diseases, the potential mechanism by which it contributes to ACMP-induced myocardial injury is unclear. This review discusses the established link between ferroptosis and cardiovascular disease and summarizes the potential role of ferroptosis in ACMP-induced myocardial injury and the detrimental effects of ACMP on the heart. Elucidating these mechanisms could guide the development of novel therapeutic strategies that target ferroptosis to mitigate ACMP-induced myocardial injury. This review aims to provide a theoretical foundation for future research on the potential use of ferroptosis as a therapeutic target for ACMP-induced myocardial injury.

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 explore the genetic etiology for a child featuring mental retardation, language delay and autism. METHODS: G-banding chromosomal karyotyping and single nucleotide polymorphism array (SNP-array) were carried out for the child and her parents. RESULTS: The child was found to have a 46,XX,dup(8p?) karyotype, for which both of her parents were normal. SNP-array revealed that the child has harbored a 6.8 Mb deletion in 8p23.3p23.1 and a 21.8 Mb duplication in 8p23.1p12, both of which were verified as de novo pathogenic copy number variants. CONCLUSION The clinical features of the child may be attributed to the 8p deletion and duplication. SNP-array can facilitate genetic diagnosis for children featuring mental retardation in conjunct with other developmental anomalies.

Venous thromboembolism (VTE) is a complication in children with acute lymphoblastic leukemia (ALL). The Chinese Children's Cancer Group-ALL-2015 protocol was carried out in China, and epidemiology, clinical characteristics, and risk factors associated with VTE were analyzed. We collected data on VTE in a multi-institutional clinical study of 7640 patients with ALL diagnosed in 20 hospitals from January 2015 to December 2019. First, VTE occurred in 159 (2.08%) patients, including 90 (56.6%) during induction therapy and 108 (67.92%) in the upper extremities. T-ALL had a 1.74-fold increased risk of VTE (95% CI 1.08-2.8, P = 0.022). Septicemia, as an adverse event of ALL treatment, can significantly promote the occurrence of VTE (P < 0.001). Catheter-related thrombosis (CRT) accounted for 75.47% (n = 120); and, symptomatic VTE, 58.49% (n = 93), which was more common in patients aged 12-18 years (P = 0.023), non-CRT patients (P < 0.001), or patients with cerebral thrombosis (P < 0.001). Of the patients with VTE treated with anticoagulation therapy (n = 147), 4.08% (n = 6) had bleeding. The VTE recurrence rate was 5.03% (n = 8). Patients with VTE treated by non-ultrasound-guided venous cannulation (P = 0.02), with residual thrombus (P = 0.006), or with short anticoagulation period (P = 0.026) had high recurrence rates. Thus, preventing repeated venous puncture and appropriately prolonged anticoagulation time can reduce the risk of VTE recurrence.

Scientific performance-based salary system is of great significance for hospitals to implement effective internal management, improve the enthusiasm of medical staff, and promote the high-quality development of public hospitals. Based on the requirements of the national salary system reform, a tertiary general hospital has been designing and implementing a performance-based salary system since 2016. The hospital has established a job evaluation index system to stratify various job sequences in the hospital, and determined the job value coefficients for different sequences and levels. It has also established a performance salary project system that covered job performance salary, specific performance salary, and innovative performance salary. In addition, the hospital has established a performance-based salary management system that covered salary standard formulation, performance salary accounting and distribution, and dynamic adjustment of the performance-based salary management system. The application of this performance-based compensation management system has achieved the matching of employee value, job hierarchy, and medical services. From 2016 to 2020, employees′ overall satisfaction with performance-based salary exceeded 85%. At the same time, the system could enhance the operational efficiency and quality of the hospital, drive technological development and scientific research innovation, playing a positive incentive role in the high-quality development of the hospital.

OBJECTIVE: To explore the genetic etiology of spontaneous abortions by using chromosomal microarray analysis (CMA). METHODS: Fetal tissues derived from 106 spontaneous abortion samples were subjected to CMA assay to detect genome copy number variants (CNVs). RESULTS: The test was successful in 94 cases (88.68%). Fifty four chromosomal abnormalities were detected, which included 44 numerical chromosomal aberrations mainly consisting of aneuploidies, triploidies and mosaicisms. Four pathogenic CNVs were detected, and two of which involved the Cri-du-chat syndrome regions. In addition, 6 chromosomal mosaicism were detected. CONCLUSION Numerical chromosomal aberrations and CNVs are the main causes for early spontaneous abortions. CMA can effectively reveal the genetic etiology of spontaneous abortions. Spontaneous abortions at gestational weeks 10 to 11⁺⁶ has the highest rate for chromosomal abnormalities, which may provide valuable information for clinical counseling.
