Objective: To explore the effectiveness of different intervention modalities on nonsuicidal selfinjury (NSSI) in adolescents, so as to provide an evidencebased basis for the intervention strategy of NSSI in adolescents. Methods: Randomized controlled trials on interventions for adolescent NSSI were retrieved from databases, such as CNKI, Wanfang, VIP, CBM, Web of Science, PubMed, Embase, and Cochrane Library, spanning from the inception of these databases to March 5, 2025. Network Metaanalysis was performed by using Stata 17.0 and Review Manager 5.3 software, and the standardized mean difference (SMD) and 95%CI were used as the effect indicators to compare the differences in the effectiveness of the interventions and rank the effect. Results: A total of 26 articles with 2 034 adolescents with NSSI were included in the study, including 10 intervention modalities:dialectical behavior therapy, emotional regulation intervention, mentalizationbased therapy, family therapy, cutting down programme, cognitive behavioral therapy, narrative therapy, stepped care approach, positive psychological intervention, and acceptance and commitment therapy. The results showed that compared with the treatment as usual, positive psychological intervention [SMD(95%CI)=-2.12(-3.51 to -0.74)], stepped care intervention [SMD(95%CI)=-2.07(-3.43 to -0.71)], and dialectical behavior therapy [SMD(95%CI)=-1.70(-2.60 to -0.80)], cognitive behavioral therapy [SMD(95%CI)=-1.54(-2.61 to -0.48)], and acceptance and commitment therapy[SMD(95%CI)=-1.50(-2.68 to -0.32)] were statistically significant differences in reducing adolescents NSSI behaviors(P<0.05). Positive psychological intervention, stepped care intervention, and dialectical behavior therapy were more effective than the mentalizationbased therapy and the cutting down programme (SMD=-2.08, -2.03, -1.66, -2.06, -2.01, -1.64,P<0.05); the area under the cumulative ranking probability graph revealed that positive psychological intervention may have the best effect in improving NSSI among adolescents (82.5). Conclusions Positive psychological interventions show the best results in improving adolescent NSSI among multiple intervention modalities. It is recommended to give priority to positive psychological interventions in clinical interventions.

Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

ObjectiveTo explore the therapeutic effect of Huangliansan on atopic dermatitis （AD） model mice induced by 2， 4-dinitrochlorobenzene （DNCB）. MethodA total of 42 male BALB/c mice were randomly divided into normal group， model group， hydrocortisone group， low， medium， and high-dose groups （0.3， 0.6， 1.2 g·kg^-1） of Huangliansan oil， and water extract group （0.6 g·kg^-1） of Huangliansan. In addition to the normal group， DNCB was applied on the back of mice in other groups to establish the AD model. On the 15^th day after DNCB stimulation， each group was given the corresponding drug or solvent， and the changes in skin lesions， dermatitis score， and frequency of scratching were observed and recorded. Hematoxylin-eosin （HE） staining was used to observe the histopathological changes in the skin and spleen. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA levels of filaggrin （FLG）， lorophane （LOR）， and involucrin （IVL） in skin， as well as immunoglobulin E （lgE）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and interferon-γ （IFN-γ） in spleen. ResultCompared with the normal group， the model group showed symptoms of skin swelling and scab， and the score of dermatitis， the frequency of scratching， and the spleen index were increased （P<0.05）. The expression levels of FLG， LOR， and IVL in skin tissue were significantly decreased （P<0.01）， and the mRNA expressions of IgE， IL-4， IL-6， IL-1β， and TNF-α in the spleen were significantly increased， while the expression level of IFN-γ was significantly decreased （P<0.01）. Compared with the model group， the symptoms of skin erythema， scaly， and scab of mice in each drug group were alleviated to varying degrees， and the score of dermatitis， the frequency of scratching， and the spleen index were decreased （P<0.05， P<0.01）. In addition， the expression levels of FLG， LOR， and IVL in the skin of mice in the drug group were increased （P<0.05， P<0.01）， and the mRNA expression of IgE， IL-4， IL-6， IL-1β， and TNF-α in spleen were decreased. IFN-γ was increased （P<0.05， P<0.01）， and the lesions of the skin and spleen were improved to varying degrees. The medium-dose group of Huangliansan oil and hydrocortisone group had the most obvious manifestations （P<0.05， P<0.01）. The indexes in the medium-dose group of Huangliansan oil were better than those in the water extract group of Huangliansan. ConclusionHuangliansan may improve the expression level of skin barrier protein， inhibit the expression of helper T cell 2 （Th2）-related inflammatory factors， increase the expression of helper T cell 1 （Th1） inflammatory factors， restore the skin barrier function and Th1/Th2 balance in the spleen， regulate the inflammatory response in the spleen of AD mice， and thus relieve AD. Huangliansan oil is more effective than water extract.

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Bacterial biofilms gave rise to persistent infections and multi-organ failure, thereby posing a serious threat to human health. Biofilms were formed by cross-linking of hydrophobic extracellular polymeric substances (EPS), such as proteins, polysaccharides, and eDNA, which were synthesized by bacteria themselves after adhesion and colonization on biological surfaces. They had the characteristics of dense structure, high adhesiveness and low drug permeability, and had been found in many human organs or tissues, such as the brain, heart, liver, spleen, lungs, kidneys, gastrointestinal tract, and skeleton. By releasing pro-inflammatory bacterial metabolites including endotoxins, exotoxins and interleukin, biofilms stimulated the body’s immune system to secrete inflammatory factors. These factors triggered local inflammation and chronic infections. Those were the key reason for the failure of traditional clinical drug therapy for infectious diseases.In order to cope with the increasingly severe drug-resistant infections, it was urgent to develop new therapeutic strategies for bacterial-biofilm eradication and anti-bacterial infections. Based on the nanoscale structure and biocompatible activity, nanobiomaterials had the advantages of specific targeting, intelligent delivery, high drug loading and low toxicity, which could realize efficient intervention and precise treatment of drug-resistant bacterial biofilms. This paper highlighted multiple strategies of biofilms eradication based on nanobiomaterials. For example, nanobiomaterials combined with EPS degrading enzymes could be used for targeted hydrolysis of bacterial biofilms, and effectively increased the drug enrichment within biofilms. By loading quorum sensing inhibitors, nanotechnology was also an effective strategy for eradicating bacterial biofilms and recovering the infectious symptoms. Nanobiomaterials could intervene the bacterial metabolism and break the bacterial survival homeostasis by blocking the uptake of nutrients. Moreover, energy-driven micro-nano robotics had shown excellent performance in active delivery and biofilm eradication. Micro-nano robots could penetrate physiological barriers by exogenous or endogenous driving modes such as by biological or chemical methods, ultrasound, and magnetic field, and deliver drugs to the infection sites accurately. Achieving this using conventional drugs was difficult. Overall, the paper described the biological properties and drug-resistant molecular mechanisms of bacterial biofilms, and highlighted therapeutic strategies from different perspectives by nanobiomaterials, such as dispersing bacterial mature biofilms, blocking quorum sensing, inhibiting bacterial metabolism, and energy driving penetration. In addition, we presented the key challenges still faced by nanobiomaterials in combating bacterial biofilm infections. Firstly, the dense structure of EPS caused biofilms spatial heterogeneity and metabolic heterogeneity, which created exacting requirements for the design, construction and preparation process of nanobiomaterials. Secondly, biofilm disruption carried the risk of spread and infection the pathogenic bacteria, which might lead to other infections. Finally, we emphasized the role of nanobiomaterials in the development trends and translational prospects in biofilm treatment.

Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System（BRICS）were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute（CLSI）. WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period，9 035 strains of Gram-negative bacteria were collected from 51 hospitals，of which 7 895（87.4%）were Enterobacteriaceae and 1 140（12.6%）were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli（ n=4 510，49.9%）， Klebsiella pneumoniae（ n=2 340，25.9%）， Pseudomonas aeruginosa（ n=534，5.9%）， Acinetobacter baumannii complex（ n=405，4.5%）and Enterobacter cloacae（ n=327，3.6%）. The ESBLs-producing rates in Escherichia coli， Klebsiella pneumoniae and Proteus spp. were 47.1%（2 095/4 452），21.0%（427/2 033）and 41.1%（58/141），respectively. The prevalence of carbapenem-resistant Escherichia coli（CREC）and carbapenem-resistant Klebsiella pneumoniae（CRKP）were 1.3%（58/4 510）and 13.1%（307/2 340）；62.1%（36/58）and 9.8%（30/307）of CREC and CRKP were resistant to ceftazidime/avibactam combination，respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii（CRAB）complex was 59.5%（241/405），while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa（CRPA）was 18.4%（98/534）. There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions，with statistically significant differences in the prevalence of CRKP and CRPA（ χ2=20.489 and 20.252， P<0.001）. The prevalence of CREC，CRKP，CRPA，CRAB，ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals（ χ2=11.953，81.183，10.404，5.915，12.415 and 6.459， P<0.01 or <0.05），while the prevalence of CRPA was higher in economically developed regions（per capita GDP ≥ 92 059 Yuan）than that in economically less-developed regions（per capita GDP <92 059 Yuan）（ χ2=6.240， P=0.012）. Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend，and Escherichia coli is ranked in the top，while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different，and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

Objective To comprehensively analyze the reported preparation methods for animal models of perimenopausal syndrome (PS), to compare the advantages and disadvantages of various preparation elements and detection indexes, so as to provide useful references for the optimization of the relevant animal models as well as the standardization of their application in the efficacy evaluation of new drugs.MethodsIn this paper, literature research methods were applied using "perimenopausal syndrome" as the subject term. The publication period of the literature was limited to January 2016 to February 2023. Relevant literature on the preparation of PS animal models was retrieved from databases such as China National Knowledge Infrastructure, Wanfang database, and PubMed. After screening the experimental literature that met the inclusion and exclusion criteria, detailed information on experimental animal strains, modeling methods, duration of drug administration, positive drugs, detection indexes and other relevant information were collected. After the above information was standardized, the PS animal model database was established using Excel 2010 software. The model preparation elements and evaluation indexes were summarized systematically, and the statistical results were processed and analyzed using Excel 2010 software.Results A total of 247 articles were screened. SD rats (164 times, 65.86%) and Wistar rats (35 times, 14.06%) were often used to prepare PS animal models. Bilateral ovariectomy (139 times, 53.87%) and natural aging (43 times, 16.80%) were chosen as modeling methods. The ages of rats used for modeling ranged from 7 weeks to 18 months, with 3-month-old rats (22 times, 21.78%) being the most common. The detection indexes were comprehensively evaluated from multiple perspectives, including serum biochemistry, vaginal exfoliated cell smear, histomorphology, general observation, behavioral observation, and organ tissue protein immunoblotting. Western medical evaluation indexes were commonly used to test the successful preparation of models, with vaginal exfoliated cell smears being the most frequently used method (125 times, 85.04%). A model was considered successfully prepared when estrous cycle disorder or irregularity was observed. Some literature also determined modeling success by detecting a significant decrease in serum estradiol levels (5 times, 3.04%). Traditional Chinese medicine (TCM) syndrome evaluation often used a combination of Chinese and Western medical evaluation indexes for comprehensive evaluation, with researchers determining the TCM syndrome through vaginal exfoliated cell smears supplemented by general observation (3 times, 2.04%).Conclusion There are many methods for preparing PS animal models, but there are still significant differences in the selection of animal species, age, criteria for successful modeling, and TCM syndrome evaluation in the related literature.

ObjectiveTo explore the possible mechanism of Changweiqing （肠胃清） in the treatment of colorectal cancer. MethodsHCT 116 cancer cells were used to prepare intestinal cancer cells with silenced polypyrimidine region binding protein 3 （PTBP3） gene and stably transfected cells with overexpressed PTBP3 gene. Stably transfected cells with silenced PTBP3， stably transfected cells with overexpressed PTBP3 and untransfected cancer cells were injected into the armpit of 72 nude mice to construct three different subcutaneous transplanted tumor models of colorectal cancer cells， including the silenced model， the overexpressed model and the control model， with 24 mice per model. Mice of each transplanted tumor modelwere randomly divided into Changweiqing （CWQ） group， oxaliplatin （OXA） group and normal saline （NS） group， with 8 mice in each group. The CWQ groups were given intragastric administration of 35.9625 g/kg of Changweiqing oral liquid and were intraperitoneally injected with 0.2ml of normal saline； the NS groups were given 0.5ml of normal saline by gavage， and intraperitoneal injection of 0.2ml of normal saline； the OXA groups were intraperitoneally injected with 5 mg/kg （0.2 ml） of oxaliplatin and given 0.5ml of normal saline by gavage. Each group was given intragastric administration once a day and intraperitoneal injection three times a week. After 31 days， the weight of subcutaneous tumors in each group was measured， and the tumor inhibition rate of the groups in each model were measured. Immunohistochemistry and other methods were used to detect the expression level of cell proliferation cell nuclear antigen Ki67 and apoptosis index. Real-time PCR and Western Blot were used to detect mRNA and protein expressions of PTBP3， signal transducer and activator of transcription 3 （STAT3） splicing isoform α （STAT3α）， STAT3 splicing isoform β （STAT3β）， B-cell lymphoma/leukemia-2 （Bcl-2） splicing isoform α （Bcl-2α）， and Bcl-2 splicing isoform β （Bcl-2β） in subcutaneous tumor cells in each group. ResultsFor all three transplanted tumor models， the weight of the subcutaneous tumors and Ki67 expression level of subcutaneous tumor tissue in all CWQ groups and OXA groups were lower than those of the corresponding NS groups， while the apoptosis level were higher （P＜0.05 or P＜0.01）. The mRNA and protein expressions of PTBP3， STAT3α， and Bcl-2α in the subcutaneous tumor tissues of the silenced model CWQ group and the overexpressed model CWQ group were lower than those of the corresponding NS groups， while the mRNA and protein expression levels of STAT3β and Bcl-2β were higher （P＜0.05 or P＜0.01）. All there groups of silenced model had lower subcutaneous tumor weight， Ki67 expression level， and mRNA and protein expression levels of PTBP3， STAT3α， and Bcl-2α in subcutaneous tumor tissue， as well as higher apoptosis level and mRNA and protein expression levels of STAT3β and Bcl-2β than those in all groups of control model； all groups of overexpressed model had higher subcutaneous tumor weight， Ki67 expression level， and mRNA and protein expression levels of PTBP3， STAT3α， and Bcl-2α ， while lower apoptosis level and mRNA and protein expression levels of STAT3β and Bcl-2β than those in all control model groups （P＜0.05 or P＜0.01）. In the control model， compared with the NS group， The tumor inhibition rate of all OXA groups was higher than that of corresponding CWQ groups， respectively. Compared to that of each control model group， the tumor inhibition rate was positive value of each silenced model group， and negative value of each overexpressed model group. ConclusionPTBP3 can promote the proliferation and inhibit apoptosis of intestinal cancer cells， upregulate the expression of STAT3α and Bcl-2α， and downregulate the expression of STAT3β and Bcl-2β in intestinal cancer cells. The meachnism of action of Changweiqing in the treatment of colorectal cancer maybe related to the inhibition of PTBP3， and regulation of the expression of STAT3α， STAT3β， Bcl-2α， and Bcl-2β.
