OBJECTIVE To analyze adverse drug reactions (ADRs) in pediatric patients with Mycoplasma pneumoniae pneumonia (MPP), and investigate the influential factors associated with the occurrence of ADRs. METHODS Clinical records of pediatric patients with MPP in Xinxiang Central Hospital (hereinafter referred to as “our hospital”) from Oct. 1st, 2023 to Sept. 30th, 2024 collected from the Hospital Information System were retrospectively reviewed using the global trigger tool (GTT). The positive triggers were further reviewed to confirm the occurrence of ADRs, and the characteristics of those ADRs were analyzed. The children were divided into the ADR group and the non-ADR group. Univariate analysis and multivariate Logistic regression analysis were performed to investigate the potential influential factors for ADRs in MPP children. RESULTS A total of 1 325 MPP children were included. Out of 24 designed triggers, 14 were positive, with a positive trigger rate of 58.3%. There were 1 301 positive trigger cases, involving 846 pediatric patients. After assessment, 399 cases of ADRs were identified in 372 pediatric patients, yielding a positive predictive value of triggers at 30.7%. The main types of ADRs were abnormal blood cells (230 cases, 57.6%), skin and its appendages damage (78 cases, 19.5%), and gastrointestinal system damage (42 cases, 10.5%), which predominantly occurred 4 days or more, within 2-3 days and within 2-3 days after medication, respectively. They were more prevalent in pediatric patients aged>3-10 years (295 cases, 79.3%). The major categories of drugs associated with ADRs included intravenous corticosteroids (209 cases), cephalosporins (180 cases), macrolides (38 cases), tetracyclines (28 cases) and traditional Chinese medicine (TCM) injections (28 cases). These ADR reports were classified into 3 types: 1 serious case, 394 general cases and 4 new cases. In terms of causality assessment, 1 case was assessed as certain, 19 cases as probable, and 379 cases as possible. In terms of ADR outcomes, 151 cases fully recovered, while the outcomes for 248 cases remained unknown. Univariate analysis and multivariate Logistic regression analysis revealed that a history of allergies [OR=5.231, 95%CI (2.004, 13.656), P<0.05], the number of medications used [OR=1.064, 95%CI (1.027, 1.103), P<0.05], and intravenous corticosteroid administration [OR=3.223, 95%CI (2.341, 4.437), P<0.05] were independent risk factors of ADRs in pediatric patients with MPP. The use of azithromycin [OR=0.544, 95%CI (0.376, 0.786), P<0.05] was identified as an independent protective factor against the occurrence of ADRs in pediatric patients with MPP. CONCLUSIONS Children with MPP in our hospital exhibit a higher incidence of ADRs, primarily involving abnormal blood cells, skin and its appendages damage, and gastrointestinal system damage. A history of allergies, the number of medications used, intravenous corticosteroid administration, and the use of azithromycin are associated with the occurrence of ADR in MPP pediatric patients.

ObjectiveTo explore the mechanism of moxibustion with the classical prescription Xiaoyaosan as the herbal cake in improving cognitive function in the rat model of chronic fatigue syndrome (CFS) by regulating autophagy via phosphatidylinosiol 3-kinase (PI3K)/autophagy key molecule yeast Atg6 homologue 1 (Beclin1) signaling pathway. MethodsFifty SPF-grade SD rats aged 6-8 weeks were randomly grouped as follows: control, model, sham cake-separated moxibustion, intragastric administration with Chinese herbs, and herbal cake-separated moxibustion, each with 10 rats. The other groups except the control group were subjected to modeling by exhaustive swimming and chronic restraint stress for 21 days, and the behavioral test was performed after modeling. Herbal cake-separated moxibustion and sham cake-separated moxibustion were carried out at Shenque (CV8), Guanyuan (CV4), Zusanli (ST36), and Qimen (LR14). The rats in the intragastric administration with Chinese herbs group were treated with Xiaoyaosan suspension by gavage. After continuous intervention for 10 days, rat behaviors were observed and the levels of interleukin (IL)-4, IL-10, blood urine nitrogen (BUN), and malondiadehyde (MDA) in the serum and hippocampal tissue of rats in each group were determined by enzyme-linked immunosorbent assay. The morphological changes of the hippocampal tissue were observed by hematoxylin-eosin staining. The relative mRNA and protein levels of PI3K and Beclin1 in the hippocampal tissue were determined by Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultsCompared with the normal group, the model group showed reduced crossings, shortened residence time in the target quadrant, and prolonged average escape latency on days 1, 2, 3, and 4 (P<0.01) in the Morris water maze test. In the new object recognition test, the model group showed decreased recognition index of exploration time and recognition index of exploration times (P<0.01), lowered levels of IL-4 and IL-10 and elevated levels of BUN and MDA in the serum and hippocampus (P<0.01), and down-regulated mRNA and protein levels of PI3K and Beclin1 (P<0.01). After treatment, compared with the model group, each treatment group showed increased crossings, prolonged residence time in the target quadrant, and shortened average escape latency on days 1, 2, 3, and 4 (P<0.05, P<0.01). In addition, the treatment elevated the levels of IL-4 and IL-10 and lowered the levels of BUN and MDA in the serum and hippocampus (P<0.05, P<0.01), and up-regulated the mRNA and protein levels of PI3K and Beclin1 (P<0.05, P<0.01). Compared with the sham cake-separated moxibustion group, the herbal cake-separated moxibustion group and the intragastric administration with Chinese herbs group showed increased crossings, prolonged residence time in the target quadrant (P<0.05), elevated level of IL-4, lowered level of MDA, and up-regulated relative mRNA and protein levels of PI3K and Beclin1 in the hippocampus (P<0.05, P<0.01). The serum levels of MDA and BUN in the intragastric administration with Chinese herbs group were significantly decreased. The average escape latency of the herbal cake-separated moxibustion group was significantly shortened on days 2 and 3 (P<0.05, P<0.01). In addition, this group showed elevated serum level of IL-4, lowered serum level of MDA, and declined BUN level in the hippocampus (P<0.05, P<0.01). Compared with the intragastric administration with Chinese herbs group, the herbal cake-separated moxibustion group presented risen serum level of IL-4 and up-regulated mRNA level of Beclin1 (P<0.05) and relative protein levels of PI3K and Beclin1 (P<0.05, P<0.01). ConclusionHerbal cake-separated moxibustion can effectively alleviate fatigue and improve the memory, reduce inflammatory response and oxidative stress, and decrease autophagy of hippocampal neurons in CFS rats by regulating the PI3K/Beclin1 signaling pathway.

Cholangiocarcinoma originates from bile duct epithelial cells. It has an insidious onset, a high degree of malignancy, a poor prognosis and a high recurrence rate. Exosomes are nanoscale vesicles with a bilayer membrane structure, containing abundant biomolecules such as DNA, RNA, proteins and lipids. Exosomes are important carriers for the exchange of substances and information between cells and are involved in a variety of pathophysiological processes. In addition, exosomes have great potential in the diagnosis and treatment of various diseases. This article reviews the role of exosomes in the occurrence and development of cholangiocarcinoma and their potential value in the diagnosis and treatment of cholangiocarcinoma.

Objective:To analyze the differentially expressed messenger RNA(mRNA), microRNA(miRNA), and long non-coding RNA(lncRNA)during the browning of mouse subcutaneous adipose tissue, construct a competitive endogenous RNA(ceRNA)network, and provide a theoretical basis for investigating the regulatory mechanisms of white adipose tissue browning.Methods:A cold-stimulated mouse model was established for transcriptome sequencing.Bioinformatics tools were employed to screen for differentially expressed mRNAs, miRNAs, and lncRNAs.An integrated mRNA-miRNA-lncRNA analysis was performed to construct a ceRNA network.Gene Ontology(GO), Kyoto Encyclopedia of Genes and Genomes(KEGG), and Gene Set Enrichment Analysis(GSEA)were conducted on the differentially expressed mRNAs and ceRNA networks to explore transcriptional regulation during the cold-induced browning of subcutaneous adipose tissue.Results:Transcriptomic analysis of the cold-stimulated model identified 4, 256 differentially expressed RNAs, which include 3, 600 mRNAs, 588 lncRNAs, and 68 miRNAs.GO and KEGG analyses revealed that the browning of white adipose tissue involves immune-related processes, such as immune system processes, immune responses, adaptive and innate immune responses, and the positive regulation of T-cell activation.A ceRNA network associated with browning regulation was constructed, comprising 233 nodes(188 mRNAs, 34 miRNAs, and 11 lncRNAs)and 351 edges.Protein-protein interaction(PPI)analysis of the mRNAs within the ceRNA network highlighted pathways including apoptosis, intracellular signaling transduction, hypoxia-inducible factor-1(HIF-1), AMP-activated protein kinase(AMPK), Janus kinase-signal transducer and activators of transcription(JAK-STAT)signaling, carbon metabolism, glycolysis, and thyroid hormone pathways, all of which regulate lipid metabolism, hypoxia, and glycolysis.Cytohubba analysis identified the top 10 hub genes: Bcl2, Src, Cebpb, Creb1, Runx1, Foxo3, Ets1, Socs3, Slc2 a4, and Pkm. Conclusions:The ceRNA network that regulates the browning of white adipose tissue is involved in various pathways, including carbon metabolism, glycolysis, thyroid hormone signaling, growth hormone signaling, prolactin signaling, as well as the HIF-1, AMPK, and JAK-STAT pathways.Key regulatory miRNAs in this context include miR-30e-5p, miR-182-5p, miR-20b-5p, miR-144-3p, miR-363-3p, miR-141-3p, miR-203-3p, and miR-107-3p.These miRNAs may serve as critical targets for inducing browning in response to cold exposure.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To investigate the differences in hippocampal subfield volumes and structural covariance network properties among patients with mild cognitive impairment (MCI) exhibiting different cognitive outcomes and normal controls (NCs), and to further evaluate the predictive value of these imaging indicators for cognitive deterioration in MCI patients.Methods:A total of 43 NCs, 65 stable MCI (sMCI), and 26 progressive MCI (pMCI) patients enrolled in the Alzheimer′s Disease Neuroimaging Initiative (ADNI) database between December 2012 and May 2016 were included in this study. Baseline demographic information and T 1-weighted magnetic resonance imaging scans were collected. Hippocampal subfield volumes were extracted using freesurfer software, and structural covariance networks of hippocampal subfields were constructed. Multivariate analysis of covariance was used to compare hippocampal subfield volumes among the 3 groups. A general linear model was applied to examine group differences in hippocampal subfield structural covariance network properties. Least absolute shrinkage and selection operator (LASSO)-Logistic regression was employed to identify imaging predictors associated with conversion to Alzheimer′s disease (AD), based on which structural, network-based, and combined predictive models were constructed. Model discrimination was evaluated using the area under the curve (AUC); internal validation was performed using Bootstrap resampling; model calibration was assessed with the Hosmer-Lemeshow test; and clinical utility was evaluated through decision curve analysis. Results:Significant differences in hippocampal subfield volumes (mm3) were observed among the 3 groups (all P<0.05, Bonferroni-corrected). Specifically, left parasubiculum (65.58±13.30, 61.96±17.56, 49.56±11.82, F=9.900), right parasubiculum (65.92±15.21, 59.45±16.65, 47.69±15.48, F=11.612), left presubiculum (277.09±39.85, 258.15±44.86, 224.05±45.05, F=14.513), right presubiculum (262.85±40.43, 247.41±43.27, 209.97±46.11, F=14.500), left subiculum (399.66±32.19, 374.25±55.83, 306.12±51.62, F=32.923), right subiculum (417.93±48.92, 376.59±51.01, 316.82±70.22, F=28.764), left cornu ammonis 1 (CA1) (592.10±83.87, 561.96±94.72, 490.06±86.89, F=13.352), right CA1 (632.15±100.09, 601.24±88.88, 531.05±110.29, F=10.579), left CA3 (191.58±30.08, 180.47±34.66, 155.08±37.82, F=12.182), right CA3 (210.42±28.92, 203.84±34.80, 176.69±41.47, F=9.597), left CA4 (224.61±28.94, 210.49±35.04, 183.98±36.89, F=16.521), right CA4 (238.49±28.14, 227.43±30.65, 200.23±42.74, F=13.702), left granule cell-molecular layer-dentate gyrus (GC-ML-DG) (259.96±36.76, 239.42±41.17, 207.61±41.84, F=19.831), right GC-ML-DG (273.98±35.12, 258.79±36.82, 227.81±49.07, F=14.204), left molecular layer (505.62±66.16, 468.58±75.17, 402.68±75.47, F=22.293), right molecular layer (527.39±72.39, 493.14±70.39, 423.81±88.09, F=19.588), left hippocampal amygdala transition area (HATA) (54.91±9.99, 49.52±9.93, 43.27±9.59, F=13.571), right HATA (58.43±9.83, 54.55±10.80, 47.12±12.54, F=10.037), left fimbria (69.94±25.04, 56.63±23.74, 40.58±19.83, F=14.846), right fimbria (68.61±26.24, 53.95±23.16, 45.25±17.04, F=10.424), left hippocampal tail (488.37±83.44, 463.54±80.33, 393.83±77.73, F=13.570), and right hippocampal tail (519.78±80.22, 498.84±81.68, 419.75±93.29, F=14.339) all showed significant group differences. Significant group differences were also observed in small-worldness metric γ (0.51±0.10, 0.51±0.08, 0.62±0.14, F=9.317), small-worldness metric λ (0.39±0.02, 0.39±0.02, 0.43±0.04, F=9.925), global efficiency (0.19±0.01, 0.20±0.01, 0.18±0.01, F=3.189), local efficiency (0.26±0.02, 0.26±0.01, 0.27±0.01, F=3.068), clustering coefficient (0.23±0.01, 0.23±0.01, 0.24±0.02, F=4.274), and characteristic path length (0.73±0.06, 0.72±0.06, 0.76±0.07, F=4.477) of the hippocampal subfield structural covariance network (all P<0.05). Specifically, the pMCI group exhibited higher γ ( t=3.773, P<0.001), λ ( t=4.060, P<0.001), local efficiency ( t=2.445, P=0.047), and clustering coefficient ( t=2.849, P=0.015) than the NCs group, and higher γ ( t=4.074, P<0.001), λ ( t=4.068, P<0.001), and characteristic path length ( t=2.986, P=0.010) but lower global efficiency ( t=-2.444, P=0.047) than the sMCI group. The AUC of the structural, network, and combined models based on LASSO-Logistic regression was 0.837, 0.861, and 0.899, respectively. After internal validation, the corrected AUC was 0.835, 0.855, and 0.889, respectively. All models demonstrated good calibration ( P>0.05), and decision curve analysis indicated favorable clinical net benefit across models. Conclusions:Both sMCI and pMCI patients exhibit widespread hippocampal subfield atrophy and altered global properties of hippocampal subfield structural covariance networks compared to NCs. The models constructed based on hippocampal subfield volumes and structural covariance networks show strong potential for predicting cognitive decline in MCI patients.

Objective:To investigate the alterations of individual metabolic brain network properties in patients with mild cognitive impairment (MCI) and their correlations with cognitive function.Methods:One hundred and five participants from Alzheimer's Disease Neuroimaging Initiative (ADNI) database enrolled from March 2012 to February 2016 were chosen, including 61 MCI patients and 44 normal controls (NC). Cognitive assessments, including mini-mental state examination (MMSE), auditory verbal learning test (AVLT), trail making test (TMT), and semantic verbal fluency (SVF) score, were performed in both groups; differences of above scores and clinical data between the participants from the two groups were compared. T1-weighted imaging and fluorodeoxyglucose positron emission tomography (FDG-PET) images were collected in both groups; individual metabolic brain networks were constructed based on differences in effect sizes between brain regions and network properties were calculated. Spatial correlation analysis was used to compare the correlations of metabolic brain networks at the individual and group levels. General linear model was employed to compare the differences in network properties between the two groups. Partial correlation analysis was used to examine the correlations of differential network properties with cognitive function in MCI patients. A support vector machine (SVM) classification model was constructed based on individual metabolic brain network properties, and receiver operating characteristic (ROC) curve was used to explore the diagnostic value of this SVM classification model in MCI.Results:(1) Compared with the NC group, the MCI group had significantly lower MMSE and AVLT-immediate recall scores, and longer TMT-A completion time ( P<0.05). (2) Spatial correlation analysis revealed a positive correlation between individual metabolic brain networks and group-level metabolic brain networks in patients of the MCI group ( r=0.825, P<0.001). No significant differences in global network properties were noted between the two groups ( P>0.05). Compared with the NC group, the MCI group significantly decreased degree centrality in the left A8vl, right A39c, and right V5/MT+ regions, increased degree centrality in the left anterior cuneus, decreased nodal efficiency in the left A8vl, right V5/MT+, and right caudal hippocampus regions, increased nodal shortest path length and nodal clustering coefficient in the left A8vl region ( P<0.05). (3) The degree centrality at the A8vl of ventral part of the left middle frontal gyrus and nodal efficiency in right caudal hippocampus region were positively correlated with AVLT-immediate recall scores ( r=0.331, P=0.010; r=0.282, P=0.030), nodal efficiency in the left A8vl region was negatively correlated with TMT-A completion time ( r=-0.470, P<0.001), and nodal efficiency in the left A8vl region was positively correlated with SVF score ( r=0.263, P=0.044). (4) Area under the curve of SVM classification model in diagnosing MCI was 0.880 (95% CI: 0.813-0.945, P<0.001), with an accuracy rate of 0.790. Conclusions:Patients with MCI have alterations in individual metabolic brain network properties, among which the degree centrality and nodal efficiency of some nodes are closely related to cognitive function changes. Models constructed based on individual metabolic brain network properties can help to effectively diagnose MCI.

BACKGROUND:Immunosuppression leads to impaired body immune function and aggravates the disease.Herb-partitioned moxibustion can effectively regulate immune function and improve immunity in the body,but its regulatory mechanism has not been elucidated. OBJECTIVE:To sequence immunosuppressed model rats treated with herb-partitioned moxibustion using bioinformatics techniques based on transcriptomics and to explore the mechanisms by which it regulates immunity. METHODS:Twenty-four Sprague-Dawley rats were randomly assigned to three groups:control,model,and herb-partitioned moxibustion groups,with eight rats in each group.The model and herb-partitioned moxibustion groups were subjected to establishment of an immune suppression model by intraperitoneal injection of cyclophosphamide at a dose of 35 mg/kg for 3 consecutive days.No interventions were administered to the control and model groups after modeling.In contrast,the herb-partitioned moxibustion group received moxibustion treatment at Zhongwan,Shenque,Guanyuan,and Zusanli acupoints using a combination of moxa and herbal cakes,once a day,for 10 consecutive days,with samples being collected the day after the end of the intervention.Peripheral blood was collected from all groups of rats to measure their white blood cell count.RNA-seq was performed on the Illumina sequencing platform,and differentially expressed genes were selected for bioinformatics analysis using the GO and KEGG databases. RESULTS AND CONCLUSION:Compared with the control group,the model group exhibited a significant decrease in white blood cell count(P<0.001).RNA-seq analysis identified 3 026 differentially expressed genes between the model and control groups,with 1 565 upregulated and 1 461 downregulated.There were 535 differentially expressed genes identified between the herb-partitioned moxibustion group and the model group,with 280 upregulated and 255 downregulated.The Venn diagram analysis revealed that 159 genes were downregulated in the model group compared with the control group.However,after moxibustion with herbal cakes,these genes were upregulated.Protein-protein interaction network analysis identified 10 core targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,Mx1,Syk,Hspa1a,and Ret.According to GO and KEGG analyses,moxibustion with herbal cakes regulated the body through pathways related to immune response,viruses,angiogenesis,and the autoimmune system.To conclude,there is a significant association between herbal cake-separated moxibustion intervention and immune suppression targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,and Mx1.The intervention exhibits regulatory effects in the pathways related to immune responses,viral activities,and angiogenesis.
