Objective: To explore the laboratory testing methods and clinical management strategies for immune hemolytic anemia induced by Ceftizoxime sodium drug-dependent antibodies. Methods: Patient blood samples were subjected to blood typing, direct antiglobulin test, and unexpected antibody identification. Ceftizoxime sodium drug-dependent antibodies were detected using the immune complex method and drug-sensitized red cell method. The properties and titers of the drug antibodies were further assessed. Flow cytometry was used to assess the complement activation capacity of the drug antibodies in vitro. Results: Direct antiglobulin tests (IgG and C3d) were positive. Ceftizoxime sodium drug-dependent antibodies were identified using both the immune complex method and the sensitized red cell method, their titers significantly increased following the addition of the drug. Flow cytometry confirmed the complement activation capability of these antibodies and identified 30 minutes as the optimal time for activation in vitro. The patient's condition improved rapidly after drug withdrawal and supportive transfusion, resulting in a favorable outcome. Conclusion: Ceftizoxime sodium can cause drug-induced immune hemolytic anemia via complement activation mediated by drug-dependent antibodies. Serological testing is essential for diagnosing drug-induced hemolytic anemia. Clinicians should be vigilant for this adverse reaction. The offending drug must be promptly discontinued, and supportive care should be initiated upon the onset of symptoms.

The chemical constituents were systematically separated from the roots of Berberis polyantha by various chromatographic methods, including silica gel column chromatography, HP20 column chromatography, polyamide column chromatography, reversed-phase C_(18) column chromatography, and preparative high-performance liquid chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic techniques(1D NMR, 2D NMR, UV, MS, and CD). Four phenylpropanoids were isolated from the methanol extract of the roots of B. polyantha, and they were identified as(2R)-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone-O-β-D-glucopyranoside(1), methyl 4-hydroxy-3,5-dimethoxybenzoate(2),(+)-syringaresinol(3), and syringaresinol-4-O-β-D-glucopyranoside(4). Compound 1 was a new compound, and other compounds were isolated from this plant for the first time. The anti-inflammatory activity of these compounds was evaluated based on the release of nitric oxide(NO) in the culture of lipopolysaccharide(LPS)-induced RAW264.7 macrophages. At a concentration of 10 μmol·L~(-1), all the four compounds inhibited the LPS-induced release of NO in RAW264.7 cells, demonstrating potential anti-inflammatory properties.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To investigate the gene expression profile of cervical exfoliated cells from woman treated by artificial cycle,and their potential association with endometrial receptivity in order to screen specific biomarkers closely related to the receptivity.Methods A total of 19 female patients were enrolled from those preparing for frozen embryo transfer(FET)at the Reproductive Center of First Medical Center of Chinese PLA General Hospital from February 2024 to October 2024.Under the artificial cycle frozen embryo transfer protocol,the endometrial tissues were collected on the 4th day after progesterone administration(P+4)to verify their endometrial receptivity status.Additionally,cervical exfoliated cells were collected on the 4th day(P+4)and the 6th day(P+6)after progesterone administration.RNA sequencing(RNA-Seq)was used to detect gene expression profiles.Differentially expressed genes(DEGs)were identified using the criteria of|log2fold change|＞1 and a false discovery rate(FDR)＜0.05,followed by bioinformatics analysis.The protein-protein interaction(PPI)network of DEGs was constructed using R software(4.4.1)and analyzed with gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG)analyses.The candidate genes were identified based on the PPI network using Cytoscape software.Quantitative reverse transcription PCR(RT-qPCR)was employed to validate the target candidate genes both in vitro and in vivo.Results The rsERT confirmed that all 19 women were in state of endometrial receptivity at P+6.RNA-Seq identified 3 458 DEGs in cervical exfoliated cells between P+4 and P+6.The up-regulated DEGs were mainly enriched in the pathways associated with immune response and cell differentiation,and the down-regulated ones were mainly enriched in the pathways associated with lipid metabolism and cell proliferation.Using maximal clique Centrality(MCC)algorithm in the PPI network,the top 20 genes were selected.Among them,6 genes,such as IFIT2,OASL,MX1,RSAD2,IFIT1 and IFIT3,tied for the first place,and the 6 genes all belong to interferon-stimulated genes(ISGs).qRT-PCR indicated that the above 6 genes showed significantly higher expression levels in the cervical exfoliated cells at the P+4 stage than the cells at the P+6 stage(P＜0.05).Conclusion There are changes in the expression levels of the genes related to immunity and cytoskeleton remodeling in cervical exfoliated cells during the endometrial receptivity phase.The decrease in the expression of ISGs may serve as a potential biomarker for endometrial receptivity.

A quadruplex RT-qPCR method was developed for rapid identification and diagnosis of transmissible gastroenteritis virus(TGEV)of swine,porcine epidemic diarrhea virus(PEDV),porcine deltacorona virus(PDCoV),and porcine rotavirus type A(PoRVA).The full-length sequences of PEDV(77 strains),TGEV(63 strains),PDCoV(17 strains)that are prevalent in China,as well as the 85 VP6 gene sequences of PoRVA,were downloaded from the NCBI database for homology analysis.Based on the relatively conserved sequences,the corresponding primers and probes for each virus were designed and used to establish the quadruplex RT-qPCR method.After optimization of the probes and the reaction conditions,the specificity,sensitivity,and repeatability were determined.Using the established method,109 clinical samples of diarrhea were tested and further compared with the results by standard method.The results showed that the quadruplex RT-qPCR method established in this experiment has good amplification effect,with the C,value linearly correlated with the copies of templates(R2＞0.99).Specificity assay demonstrated that the quadruplex RT-qPCR method can identify TGEV,PEDV,PDCoV,PRoVA strains,and do not de-tect African swine fever virus(ASFV),porcine circovirus type 2(PCV2),porcine reproductive and respiratory syndrome virus(PRRSV),classical swine fever virus(CSFV),pseudorabies virus(PRV)and other epidemic viruses.Sensitivity assay showed that the detection limits for TGEV,PEDV,PDCoV and PoRVA were 10,20,20 and 50 copies/μL,respectively.The method exhibits excellent reproducibility,with coefficients of variation(Cv)for both intra-and inter-assay repli-cates being less than 1％.Detection of 109 samples of diarrhea by this method yielded the coinci-dence rate of 100％with the industry standard,indicating high practical applicability.The devel-oped method possesses the advantages of strong strain compatibility,high sensitivity,strong speci-ficity,good repeatability and stability.It is suitable for virus diagnosis and large-scale clinical sam-ple testing,providing technical support for disease prevention and control as well as epidemiologi-cal investigation.

Objective:To investigate the clinical value of changes in serum total cholesterol (TC), chitinase protein-40 (YKL-40), and B7 homolog 4 (B7-H4) levels in patients with severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS).Methods:A total of 388 SAP patients admitted to the First Affiliated Hospital of Xi'an Medical College from January 2022 to May 2024 were selected as the study group. They were grouped into the ACS group (227 cases) and a non-ACS group (161 cases) based on whether they had concurrent ACS. Another 215 individuals who underwent health check up were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was applied to detect serum levels of TC, YKL-40, and B7-H4. Spearman test was applied to analyze the correlation between serum TC, YKL-40, B7-H4 levels and Acute Physiology and Chronic Health Status Scoring System Ⅱ(APACHE Ⅱ) score and intra-abdominal pressure (IAP)value. Multivariate Logistic regression was applied to analyze the influencing factors of SAP patients complicated ACS. The receiver operating characteristic (ROC) curve was applied to analyze the clinical diagnostic value of serum TC, YKL-40, B7-H4 levels in SAP patientscomplicated with ACS.Results:The serum levels of TC, YKL-40, and B7-H4 in the study group were higher than those in the control group : (5.79 ± 0.81) mmol/L vs. (4.67 ± 0.57) mmol/L, (49.46 ± 7.51) μg/L vs. (36.82 ± 5.93) μg/L, (63.66 ± 11.23) μg/L vs. (52.85 ± 9.21) μg/L, there were statistical differences ( P<0.05). The results of single factor analysis showed that time of stay in intensive care unit (ICU), C-reactive protein (CRP), white blood cell count (WBC), blood amylase (AMY), APACHEⅡ score, IAP value, serum TC, YKL-40, B7-H4 levels and heart rate were the risk factors for ACS in SAP patients ( P<0.05). The results of correlation analysis showed that the levels of serum TC, YKL-40 and B7-H4 were positively correlated with APACHEⅡ score and IAP value (the r value were 0.459, 0.511, 0.445 and 0.742, 0.794, 0.761, P<0.05). Multivariate Logistic regression analysis showed that time of stay in ICU, APACHE Ⅱ score, IAP value and high levels of serum TC, YKL-40 and B7-H4 were independent risk factors for ACS in SAP patients ( P<0.05). ROC curve analysis results showed that the area under the curve(IUC) of serum TC, YKL-40 and B7-H4 predicted SAP patients with ACS was 0.868. Conclusions:The levels of serum TC, YKL-40, and B7-H4 are higher in patients with SAP complicated with ACS, and their combined detection has better clinical value for SAP complicated with ACS patients.
