OBJECTIVE To form an expert consensus addressing clinical issues regarding the use of parenteral direct thrombin inhibitors （DTIs） in special populations. METHODS Led by the Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital（the Affiliated Hospital of UESTC）， a multidisciplinary working group was formed comprising experts from multiple fields， including clinical pharmacy， cardiac surgery， obstetrics， pediatrics and evidence-based medicine. Through literature review and the Delphi method， clinical questions regarding the efficacy and safety of parenteral DTIs used in special populations were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” （PICO） framework；systematic searches were conducted in CJFD， PubMed， Embase and other databases. Relevant evidence from randomized controlled trials，cohort studies and systematic reviews were included and synthesized. Evidence quality was assessed using the Grading of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through three rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven clinical questions were ultimately selected （with a consensus rate exceeding 90%）， resulting in the formulation of seven recommendations on the use of parenteral DTIs in special populations， including children， pregnant women， patients with hepatic or renal impairment， patients with mesenteric venous thrombosis， and individuals with thrombophilia. These recommendations clarify the preferred agents， dosing ranges， monitoring parameters， and safety management strategies for parenteral DTIs in these special populations. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in special populations.

A recombinant adenovirus(rAd)for expression of Mycobacterium tuberculosis(M.tb)c-di-AMP phosphodiesterase CnpB was constructed,and its induced humoral immune response was detected.The codon-optimized gene of M.tb CnpB was cloned into the adenoviral plasmid pcADV.The recombinant plasmid pcADV-CnpB was transfected into HEK293T cells,and expression was detected with Western blot.The recombinant plasmid pcADV-CnpB and the backbone plasmid were co-transfected into HEK293T cells to obtain the recombinant adenovirus rAd-CnpB.rAd-CnpB was amplified in HEK293T cells,and the target protein expression of rAd-CnpB was detected with Western blot and immunofluorescence.Mice were immunized with rAd-CnpB intranasally,and their sera and bronchoalveolar lavage fluid(BALF)were collected.ELISA was used to detect levels of antigen-specific antibodies.Restriction enzyme digestion and sequencing indicated that the recombinant plasmid pcADV-CnpB was successfully constructed and led to protein expression in eukaryotic cells.rAd-CnpB was packaged and produced in HEK293T cells.After amplification and purification,rAd-CnpB with a titer of 5.53×1010 PFU/mL was obtained.rAd-CnpB led to CnpB expression in HEK293T cells.Intranasal immunization with rAd-CnpB increased levels of IgG and secretory IgA in BALF and led to high levels of IgG in sera.rAd-CnpB,the recombinant adenovirus for expression of c-di-AMP phosphodiesterase CnpB was successfully constructed,and was found to induce antigen-specific humoral and mucosal immune responses through mucosal immunization.Thus,rAd-CnpB may be used in further research on new TB vaccine strategies.

Objective To observe the association between afterschool physical exercise and sleep quality among preschool children,and to explore the proper afterschool physical exercise model for better sleep quality.Methods A cross-sectional study was conducted.From Apr to Jun 2024,a total of 1 430 children from three public kindergartens in Minhang district were enrolled to participate in the survey.Parents were invited to complete the basic sociodemographic information,afterschool physical exercise information and the Children's Sleep Habits Questionnaire.One-way ANOVA and linear mixed effects models were used to explore the relationship between afterschool exercise and sleep quality.Results A total of 1 430 questionnaires were sent out and 1 384 were recovered with a recovery rate of 96.78%.Among them 1 366 were valid,with an effective rate of 95.52%.The average age of the children was(5.19±0.87)years old with gender ration of 1.07∶1(male:female).The prevalence of poor sleep quality was 80.60%(regarding a CSHQ total score>41 as cutoff).A one-way ANOVA indicated that time on afterschool physical exercise was significantly associated with sleep duration,Night waking,and sleep onset delay(P<0.05).After adjusting for age,gender,the only child or not,main caregiver,and parental education and occupation,linear mixed effects models showed that engaging in afterschool physical activity for at least 180 mins per week has a statistically significant predictive effect on sleep duration scores(β=-0.50,z=-4.52,95%CI:-0.72,-0.28,P<0.001),night waking scores(β=-0.16,z=-2.34,95%CI:-0.29,-0.02,P=0.020),and sleep onset delay scores(β=-0.14,z=-2.35,95%CI:-0.26,-0.02,P=0.019).Conclusion Afterschool exercise was significantly associated with sleep quality among preschool children in Minhang district of Shanghai.The time≥180 min on afterschool exercise per week in preschool children was significantly positively associated with maintaining sleep duration,reducing night wakings and shortening the latency to fall asleep.The habit of afterschool exercise and the time on afterschool exercise should be emphasized by parents and the society to improve sleep quality among preschool children.

Objective To elucidate the mechanisms of trauma-induced coagulopathy(TIC),clarify the specific pathogenic factors and pathophysiological processes,and discover the effective diagnostic indicators and therapeutic targets.Methods Transcriptomic data of traumatic hemorrhagic shock patients were obtained from the Gene Expression Omnibus(GEO)to identify differentially expressed genes(DEGs).Coagulation-related genes(CRGs)from the Kyoto Encyclopedia of Genes and Genomes(KEGG)were intersected with DEGs.Machine learning algorithms,including least absolute shrinkage and selection operator(LASSO)and random forest(RF),were applied to identify key genes.The CIBERSORT algorithm was used to analyze the correlation between key genes and immune cell infiltration.Through consensus clustering,subtype analysis was conducted on trauma patients to compare the infiltration of immune cells.A rat model of traumatic hemorrhagic shock was established to validate coagulation function and the expression of key genes.Results The dataset included samples from 17 healthy controls and 478 patients with traumatic hemorrhagic shock.A total of 6 315 DEGs were identified under the screening criterion of corrected P<0.05.Gene set enrichment analysis(GSEA)showed that the up-regulated DEGs were significantly enriched in the glucose metabolism pathway,while the down-regulated DEGs were enriched in the immune reaction-related pathways.Through cross-analysis of DEGs and CRGs,a total of 65 differentially expressed coagulation-related genes(DE-CRGs)were screened out.GO functional enrichment showed that these genes were mainly located in secreting granular membranes and platelet α-granules,and were involved in physiological processes such as blood coagulation,regulation of body fluid levels,and wound healing.KEGG pathway analysis revealed that these genes were significantly enriched in pathways such as platelet activation,complement and coagulation cascade reactions,Rap1 signaling pathway,and human cytomegalovirus infection.Six key DE-CRGs were identified through machine learning.Receiver operating characteristic(ROC)curve analysis indicated that these genes had good diagnostic efficacy.CIBERSORT analysis revealed a significant correlation between key genes and immune cell infiltration.Patients were classified into two subtypes based on the six key genes:subtype A was rich in CD8+T cells and activated NK cells,presented an immune-active state;subtype B was mainly composed of monocytes and resting NK cells,with insufficient activation of immune pathways.Animal experiments on rats showed that hemorrhagic shock can lead to coagulation dysfunction.The results of qRT-PCR further confirmed that the expression trend of key genes was consistent with the results of bioinformatics analysis.Conclusion In this study,through transcriptomics and machine learning methods,six key genes closely related to TIC were systematically screened out,namely GNA13,PIK3R3,ITGAM,MAPK14,PPP1CC and LYN,and their close connections with coagulation function and immune infiltration were revealed.Animal experiments have further verified the value of these genes as potential diagnostic and therapeutic targets.

Objective:To explore the cardioprotective effects of icariin (ICA) against radiation-induced cardiac disease (RICD) in C57BL/6 mice.Methods:A total of 48 female C57BL/6J mice aged 6-8 weeks were randomly divided into three groups: the control group (CON), the irradiation group (IR), and the irradiation combined with icariin group (IR+ ICA), with 16 mice in each group. The IR and IR+ ICA groups received a single cardiac irradiation at a dose of 30 Gy, while the CON group received no radiation treatment. The IR+ ICA group was treated with ICA (70 mg·kg -1·d -1) two weeks before irradiation until the end of the experiment through intragastric administration. In contrast, the CON and IR groups were treated with an equal volume of vehicle solution (0.5% sodium carboxymethyl cellulose, NaCMC) via intragastric administration. The mice′s mental status, food intake, body weight, and survival rates were monitored during the experiment. At two weeks post-irradiation, the venous blood of the mice was collected and serum was separated for the enzyme-linked immunosorbent assays (ELISA) of creatine kinase MB isoenzyme (CK-MB) and cardiac troponin T (cTnT/TNNT2). At 12 weeks post-irradiation, the cardiac function of the mice was assessed using echocardiography. After the mice were euthanized under anesthesia, the histopathological changes and fibrosis degree of their myocardial tissues were assessed using hematoxylin and eosin (HE) and Masson′s trichrome staining, followed by the calculation of collagen volume fraction (CVF). The differential gene expression of brain natriuretic peptide (BNP), transforming growth factor-β (TGF-β), and interleukin-6 (IL-6) in the cardiac tissues of the mice was detected using real-time reverse transcription-polymerase chain reaction (RT-PCR). Apoptosis-related proteins and proteins associated with the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathway were determined using Western blotting. The survival curves of the mice were plotted using Kaplan-Meier, and the survival differences of the mice among various groups were compared using the log-rank test. Results:After irradiation, the mice in the IR group showed lethargy, as well as decreased food intake and activity, while these symptoms in the IR+ ICA group were significantly alleviated. At two weeks post-irradiation, the CK-MB and cTnT levels of the IR group were significantly elevated compared with the CON group ( t = 5.28, 8.89, P < 0.01). At 12 weeks post-irradiation, the mice in the IR group exhibited significantly decreased body weight ( t = 2.47, P < 0.05) and decreased survival rates ( HR = 8.25, 95% CI: 1.157-58.770, P < 0.05) compared with the CON group. Echocardiography revealed that the IR group featured decreased left ventricular ejection fraction (EF), decreased fractional shortening (FS), and increased left ventricular end-diastolic diameter (LVDD) compared with the CON group ( t = 7.02, 4.45, P < 0.05). Histopathological examination revealed that the IR group suffered from cardiomyocyte edema, disordered arrangement, and increased fibrosis, with an elevated CVF. The IR group exhibited significantly upregulated gene expression of BNP, TGF-β, and IL-6 in cardiac tissues compared with the CON group ( t = 4.23, 6.39, 4.61, P < 0.05). After-irradiation, the IR group exhibited upregulated apoptosis-related proteins Cleaved Caspase-3 and Bax ( t = 6.29, 9.54, P < 0.05), decreased Bcl-2 expression ( t = 8.20, P < 0.001), and decreased phosphorylation levels of PI3K and Akt ( t = 6.47, 3.42, P < 0.001). The symptoms of the mice were partially ameliorated after treatment with ICA. Specifically, the mice in the IR+ ICA group exhibited higher body weight ( t = 5.13, P < 0.001) and significantly higher survival rates ( HR = 0.121, 95% CI: 0.017-0.864, P < 0.05) than the IR group. Compared to the IR group, the IR+ ICA group showed elevated cardiac function indicators EF and FS( t = 3.23, 3.05, P < 0.05), and reduced LVDD ( t = 3.02, P < 0.05). The histopathological analysis revealed mitigated edema and disordered arrangement of cardiomyocytes in the IR+ ICA group. Furthermore, the IR+ ICA group exhibited significantly lower BNP, TGF-β, and IL-6 expression levels than the IR group ( t = 2.83, 4.15, 2.96, P < 0.05). The expression of apoptosis-related proteins Cleaved Caspase-3 and Bax was lower ( t = 3.23, 3.24, P < 0.05), Bcl-2 expression was higher ( t = 5.92, P < 0.001), and restored phosphorylation levels of PI3K and Akt ( t = 2.89, 8.35, P < 0.001). Conclusions:Icariin has protective effects against the RICD. It alleviates cardiomyocyte apoptosis possibly by upregulating the phosphorylation levels of PI3K and Akt.
