Objective: To investigate the correlation between sleep fragmentation and body composition/blood pressure in female students of middle school, so as to provide theoretical guidance for preventing health risks associated with sleep fragmentation. Methods: From September 2022 to December 2023, 505 female students aged 12-15 years in Nanyang City were selected through stratified cluster random sampling and conducted Pittsburgh Sleep Quality Index(PSQI) survey. Participants were divided into Q 1- Q 4 groups based on sleep fragmentation index (SFI) quartiles. Body composition and blood pressure measurements were measured by adopting body composition analyzer and traditional mercury sphygmomanometer, and data were analyzed using χ 2 tests and linear regression. Results: Significant intergroup differences for Q 1- Q 4 were observed with increasing SFI levels for body mass index(BMI), fat percentage, muscle mass, bone mass, trunk fat percentage, systolic blood pressure, diastolic blood pressure, and PSQI total scores ( F =15.25,7.33,8.38,5.97,11.24,16.85,6.87,15.73, all P <0.05). SFI showed positive correlations with BMI, fat percentage, trunk fat percentage, and blood pressure( β =0.37,0.45,0.34,0.42,0.38), but negative correlations with muscle mass and bone mass( β =-0.35,-0.48) (all P <0.05). The χ 2 trend test revealed a significant increase in hypertension detection rates with elevated SFI ( χ 2=42.75, P <0.05). The χ 2 testing demonstrated statistically significant differences in hypertension incidence among different quartiles groups ( χ 2=14.16, P <0.05). After adjusting the significance level, hypertension incidence differences remained significant between Q 1and Q 4 ( χ 2=10.77), Q 2 and Q 4 groups ( χ 2=6.28) (both P <0.008 3). Conclusions Sleep fragmentation correlates significantly with body composition and blood pressure indicators in female students of middle school. Implementing sleep fragmentation interventions is essential for safeguarding female students health in middle school.

A 62-year-old male, was admitted to the hospital, with a chief complaint of fever lasting over 10 days and leukopenia and thrombocytopenia for 2 days. Ten days prior to admission, the patient experienced intermittent fever without obvious incentive factors. The breath sounds in both lungs were coarse, without accompanying dry or moist rales. Color Doppler Ultrasound indicated mild splenomegaly and multiple lymphadenectasis in the bilateral cervical, axillary, and inguinal regions. Morphological examination of bone marrow cells demonstrated abnormally large blasts, with some of the nuclei being rather irregular and cytoplasmic vacuoles. Immunophenotyping results identified this group of blast cells as immature monocytes. Karyotype analysis of chromosomes showed clonal abnormalities, with 19 out of 20 cells exhibiting near-tetraploid karyotypes, including complex karyotypic abnormalities involving chromosome17.Targeted next-generation sequencing (NGS) detected gene mutations associated with hematological malignancies that have definite or potential clinical significance,including TP53, SRSF2, STAG2, and ARID2, with variant allele frequencies (VAF) of 63.10%, 30.30%, 0.80%, and 0.60%, respectively. Integrating laboratory findings, the diagnosis was diagnosed as AML-M5 at high-risk. After receiving chemotherapy with the regimen of azacitidine combined with venetoclax, the patient passed away more than 20 days later.

Objective To investigate the role of trichostatin A(TSA)in regulating CD4+T cell subpopulations during Escherichia coli(E.coli)inflammatory infections.Methods Male mice(8 weeks old,weighing 22～25 g)were randomly divided into 3 groups(n=16):a dimethyl sulfoxide(DMSO)control group,an infection group(DMSO+E.coli),and an intervention group(E.coli+TSA).E.coli was administered via intraperitoneal injection at a concentration of 3×10? CFU/mL to establish an infection model.The E.coli+TSA group was further subdivided into 3 subgroups based on different TSA concentrations(2.5,5.0,10.0 mg/kg).Then the samples were collected at different time points(12,24,48,96 h)after TSA intervention.The efficacy of TSA in treating E.coli-induced inflammatory responses and its relationship with CD4+T cell subsets were evaluated by survival rate observation,body weight monitoring,histopathological staining for small intestine,ELISA detection,transcriptomics sequencing,flow cytometry and RT-qPCR analysis.Results Compared with the E.coli group,5 mg/kg TSA significantly increased survival rate,suppressed body weight loss,improved pathological damage in the small intestinal,reduced serum TNF-α level in 24 h after infection(P<0.000 1),and elevated IL-10 level(P<0.05).Transcriptomic analysis revealed that 5 mg/kg TSA intervention for 24 h modulated the T cell differentiation signaling pathways,including those regulating FoxO,Th17,and Th1/2.Flow cytometry and RT-qPCR results showed that compared to the E.coli group,5 mg/kg TSA down-regulated the expression of the Th17 cell marker RORγt in mice 96 h after infection while significantly up-regulated the expression of the Treg cell marker Foxp3(P<0.05).Conclusion TSA may alleviate bacterial infectious inflammatory diseases by regulating the differentiation of CD4+T cells toward the Treg subset while simultaneously inhibiting their differentiation toward the Th17 subset,thereby suppressing the release of proinflammatory cytokines.

Objective To investigate the therapeutic potential and prophylactic value of concomitant administration of nonsteroidal anti-inflammatory drug(NSAID)and antimicrobial agents in mitigating the incidence and severity of trauma-induced sepsis.Methods A retrospective cohort study encompassed the collection of clinical records from trauma patients managed in the department of intensive care unit(ICU)of Daping Hospital,Army Medical University(Third Military Medical University)from June 2008 to June 2024.Based on administered therapeutic protocols,patients were stratified into a control group(receiving antibiotic monotherapy)and a experimental group(undergoing adjunctive therapy with NSAID in conjunction with antimicrobial agents).Intergroup comparisons were performed to elucidate differences in baseline clinical characteristics and laboratory indices pertinent to therapeutic outcomes.Results A total of 268 trauma patients were included,with 72 patients in the control group and 196 patients in the experimental group.The majority of cases involved open trauma(67.5%)and injuries sustained from traffic accidents(44.0%),reflecting the principal mechanisms of injury.The respiratory tract was the most common site of infection(67.5%),with Acinetobacter baumannii(A.baumannii)emerging as the leading causative microorganism(18.0%).Among therapeutic agents,ibuprofen represented the most frequently employed NSAID(59.8%),whereas cephalosporins constituted the predominant class of antimicrobials(30.5%).Following intervention,the lymphocyte percentage(LYM%)was markedly elevated in the experimental group relative to control group[0.14(0.09,0.20)vs.0.12(0.09,0.15),P<0.01].In contrast,the levels of white blood cell count(WBC),neutrophil percentage(NEU%),D-dimer,glucose(Glu),and lactic acid(Lac)were significantly reduced[WBC(×109/L):8.82(6.36,12.96)vs.12.10(7.78,15.54);NEU%:0.76(0.67,0.81)vs.0.78(0.72,0.83);D-dimer(μg/L):2208.0(889.5,3301.5)vs.2943.9(1735.4,4997.6);Glu(mmol/L):6.8(6.2,7.9)vs.7.7(6.6,9.2);Lac(mmol/L):0.9(0.6,1.2)vs.1.1(0.8,1.5),all P<0.05].The experimental group demonstrated a significantly reduced incidence of traumatic sepsis compared with the control group[15.8%(31/196)vs.26.4%(19/72),P<0.05].Conclusion The combination of NSAID and antimicrobial agents exerts its protective effect by attenuating inflammatory and stress responses,reestablishing immune homeostasis,correcting coagulopathy,and enhancing tissue perfusion,thereby significantly decreasing the incidence of traumatic sepsis and contributing to improved prognostic outcomes in injured patients.

Theranostics in nuclear medicine is an important direction for the precision medicine. Radionuclide therapy based on small molecules/peptides often requires high doses. Improving the utilization efficiency of radionuclides, optimizing the pharmacokinetics of radionuclide therapeutic molecular probes as well as increasing the target to non-target ratio have become the international hot frontiers in the field of radiotheranostics. Evans blue (EB) motif uses endogenous albumin as a reversible carrier, and the small molecule and polypeptide structure modified based on EB can effectively extend the half-life in the blood and substantially increase the uptake, accumulation and retention of radiopharmaceuticals in target lesions, and thereby enhance the therapeutic effect and reduce the dosage of nuclides. This article focuses on the research of EB modified radiopharmaceuticals for theranostics.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).
