Objective: To systematically evaluate the performance of machine learning (ML) models in predicting non suicidal self injury (NSSI) behavior among adolescents, providing an evidence based foundation for the development of clinically applicable risk assessment tools. Methods: A comprehensive search was conducted in PubMed, Embase, Web of Science, CNKI, and Wanfang databases for relevant studies from their inception to July 21, 2025. The Prediction Model Risk of Bias Assessment Tool (PROBAST) was used to evaluate the methodological quality of the included studies. Stata 18 software was used to calculate the area under the receiver operating characteristic curve (AUC) of the models, and publication bias assessment, sensitivity analysis, and Egger s test were performed. Results: The total of 12 studies (42 prediction models) involving 58 070 adolescents were included. There were 15 machine learning algorithms in total, among which Random Forest, Logistic Regression, XGBoost, and Support Vector Machines were the most frequently utilized. The most common predictors were gender (female), family function, depression, emotion regulation, and age. All 12 included studies exhibited a high risk of bias. The pooled AUC was 0.80 (95% CI =0.78-0.82), although heterogeneity was substantial ( I 2=95.8%, P <0.01). Sensitivity analysis confirmed the robustness of these findings (no overlap in 95% CI ), while Egger s test indicated the presence of publication bias ( P <0.05). Conclusions Machine learning demonstrates potential in the risk prediction of adolescent NSSI, but existing models have a high risk of bias. Future research should focus on improving methodological quality and optimizing model reliability through rigorous external validation.

The incidence rate of hepatic fibrosis remains at a high level， and there is still a lack of specific therapeutic drugs， posing a serious threat to human health. As a type of natural active components widely present in plants， flavonoids have multiple physiological functions such as antioxidant， anti-inflammatory， and anti-fibrotic activities， and a large number of studies have confirmed the anti-hepatic fibrosis effect of flavonoids. As for the mechanism of action， flavonoids can target the functions of hepatic stellate cells by inhibiting their proliferation and differentiation， promoting their apoptosis， regulating the level of autophagy， reducing the formation of extracellular matrix， and regulating iron metabolism in hepatic stellate cells， and meanwhile， they can inhibit chronic liver inflammatory response， improve oxidative stress status， regulate intestinal flora balance， and block epithelial-mesenchymal transition， thereby blocking the progression of fibrosis through multiple dimensions. At the level of signaling pathways， flavonoids mainly exert an anti-fibrotic effect by regulating the abnormal activation of the signaling pathways such as transforming growth factor-β1/Smad， Janus kinase/signal transducer and activator of transcription， nuclear factor erythroid 2-related factor 2， nuclear factor-kappa B， phosphatidylinositol 3-kinase/protein kinase B， mitogen-activated protein kinase， Wnt/β-catenin， and adenosine 5'-monophosphate-activated protein kinase. This article summarizes the research advances in the anti-fibrotic effect of flavonoids， in order to provide a theoretical basis for further exploring their medicinal potential.

Objective To evaluate the application of evidence-based perioperative patient-controlled analgesia(PCA)management in patients with liver cancer receiving transcatheter arterial chemoembolization(TACE)treatment.Methods By using the application model of clinical evidence-based practice,the review indicators were formulated based on the best evidence.The baseline assessment was conducted,the barrier factors were analyzed,the best clinical decision was made,the implementation steps of PCA management,including training,monitoring,education,etc.were refined,and two rounds of clinical review were carried out.The knowledge-belief-practice level and the implementation of review indicators in 50 medical and nursing staff engaged in PCA management,as well as the changes in pain scores,the incidence of adverse reactions due to PCA management,and the patient's satisfaction in 159 patients after the application of evidence were compared with their corresponding values determined before the application of evidence.Results After implementing the evidence-based practice plan and applying the evidence,at multiple time points the pain scores and the incidences of adverse reactions were decreased significantly(P＜0.05),the patient's satisfaction increased remarkably(P＜0.01),the execution rate of medical and nursing staff for the review indicators were strikingly increased(P＜0.01),and the knowledge-belief-practice level concerning PCA management was prominently improved(P＜0.01).Conclusion The implementation of perioperative PCA management in patients with liver cancer receiving TACE treatment can help to reduce the perioperative pain level,improve the patient discomfort,increase the patient's satisfaction degree,and improve the ability of medical staff in performing PCA management and evidence-based practices.

Diabetes mellitus has the characteristics of chronic inflammatory diseases,often accompanied by intestinal flora disorders.Based on the TCM theory of"stomach exuberance and spleen deficiency",combined with modern medical research,this article explained the occurrence and development of diabetes mellitus from intestinal flora and inflammatory reaction.Diabetes mellitus was divided into three categories:stomach heat and deficiency of spleen yin,stomach heat and deficiency of spleen qi,and stomach heat and deficiency of spleen yang,and summarized the three methods of"clearing and draining heat,nourishing yin and moistening intestine","clearing dampness and heat,strengthening spleen and qi"and"clearing dampness and heat,strengthening spleen and warming yang",which could treat diabetes mellitus by improving intestinal flora disorder and reducing inflammatory reaction.

Objective To investigate and compare the effects of electroacupuncture and dexamethasone on lung function and histomorphology and behavior in the offspring of perinatal nicotine exposure(PNE)rats.Methods Twenty-four pregnant Sprague-Dawley rats were randomly divided into control,model,electroacupuncture shallow needling,and dexamethasone groups using the random number table method(n=6 rats per group).A pulmonary dysplasia model in offspring rats with PNE was prepared by cervicodorsal subcutaneous injection with nicotine,and successful establishment of the model was confirmed by demonstrating statistically significant differences in growth parameters,lung function,and lung morphology compared to the control group.From the sixth day of maternal conception,the control group received cervicodorsal subcutaneous injection with 0.9%sodium chloride solution(1 mg/kg once per day),and the remaining groups were similarly injected with nicotine(1 mg/kg once per day).Concurrent with the nicotine injections,the electroacupuncture shallow needling group received electroacupuncture interventions at the"Zusanli"(ST 36)acupoint on both sides once a day for 20 min.In contrast,the offspring rats in the dexamethasone group received intraperitoneal dexamethasone injections from postnatal day 8(1.5 mg/kg once per day for 3 days),with a later dose of 0.75 mg/kg once per day for 4 days.Following successful model establishment,four offspring per rat were retained in each group using the random number table method.Until the 21st day after the birth of the offspring,using the random number table method,one offspring randomly selected from the four retained offspring per rat in each group was assigned to growth parameter assessment including body weight,lung weight,and lung index;simultaneously,one offspring was randomly selected for pulmonary function which was detected by a small animal pulmonary function machine,with the parameters of forced vital capacity(FVC),functional residual capacity(FRC),dynamic lung compliance(Cdyn),peak expiratory flow(PEF),peak inspiratory flow(PIF),and airway resistance(RL);concurrently,one offspring was randomly selected for hematoxylin and eosin staining to observe the histomorphology of the lung tissue,alveolar numbers,and mean alveolar septal thickness;additionally,one offspring was randomly selected for Morris water maze testing to evaluate the effects of the two intervention methods on learning and memory capabilities in offspring rats with PNE.Results Compared with the control group,the body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,alveolar number,platform crossing times,target quadrant time percentage,and target quadrant path percentage in the Morris water maze experiment were significantly decreased in the offspring rats of the model group(P<0.01).In contrast,PIF,RL,average thickness of alveolar septa,and latency of the Morris water maze experiment were significantly increased in the offspring rats of the model group(P<0.01).Compared with the model group,both electroacupuncture shallow needling group and dexamethasone group exhibited significant increases in body weight,lung weight,lung index,FVC,PEF,FRC,Cdyn,and alveolar numbers(P<0.05,P<0.01),along with significant decreases in PIF,RL values,and mean alveolar septal thickness(P<0.01).However,in the Morris water maze experiment,compared with the model group,the electroacupuncture shallow needling group demonstrated significantly more platform crossing times and a higher target quadrant time percentage and target quadrant path percentage(P<0.01),coupled with reduced latency period(P<0.01),whereas the dexamethasone group showed no significant differences compared to the model group.Compared to the electroacupuncture shallow needling group,the dexamethasone group showed significantly less platform crossing times and a lower target quadrant time percentage and target quadrant path percentage,coupled with increased latency period(P<0.01).Conclusion Both electroacupuncture and dexamethasone demonstrated protective effects on lung development in PNE offspring rats by ameliorating lung histomorphology and pulmonary function.However,offspring receiving late,small-dose,short-course dexamethasone exhibited inferior learning and memory capabilities,whereas the electroacupuncture group showed significantly superior cognitive performance compared to the dexamethasone group.

The bioactivity-guided isolation of potentially active natural products has been widely utilized in pharmaceutical discovery. In this study, by screening fungal extracts against coxsackievirus B3 (CVB3), three new aspochalasins, templichalasins A‒C (1‒3), along with six known aspochalasins (4‒9) were isolated from an active extract derived from the endophytic fungus Aspergillus templicola LHWf045. Compound 1 features a unique 5/6/5/7/5 pentacyclic ring system, while compounds 2 and 3 possess unusual 5/6/6/7 tetracyclic skeletons. Their structures were characterized through extensive spectroscopic analyses, electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. Additionally, we demonstrated that compound 4 can be readily converted into compounds 1‒3 under mild acidic conditions and proposed a plausible mechanism for this conversion. Bioactivity evaluation of compounds 1‒9 against CVB3 revealed the inhibitory effects of all compounds against the virus. Notably, compound 9 exhibited superior antiviral activity, surpassing the commercial drug ribavirin in selectivity index (SI) value.

Guided by Zhang Zhongjing's axiom that"blood stasis induces water",this study develops stage-specific treatment strategies for edema in Kidney Consumption Disorder by examining its four-stage pathogenic progression:Sluggish Flow → Stagnant Obstruction → Depressed Accumulation → Stasis Congelation.We propose an integrated approach that reinforces the root by warming the kidney and replenishing essence,while addressing the branch by activating blood circulation and promoting diuresis.Stage-specific interventions include:for the Sluggish Flow Phase,warming and tonifying kidney Yang combined with unblocking Yang to promote uri-nation;for the Stagnant Obstruction Phase,warming the kidney and replenishing essence supported by activating blood circulation and freeing the collateral channels;for the Depressed Accumulation Phase,quickening blood and resolving stasis,regulating Qi and trans-forming turbidity,along with warming the kidney and strengthening essence;and for the Stasis Congelation Phase,expelling stagnant accumulations while simultaneously regulating essence and blood.This framework advances novel pattern-determined strategies for Kid-ney Consumption edema management.

Objective:To discuss the effect of knock down of gene of kinesin family member 3B(KIF3B),an important component of primary cilia(PC)of in mouse embryonic palatal mesenchymal on the autophagy level of cells(mEPMCs)cells,and to clarify its mechanism.Methods:The mEPMCs from gestational day 14.5 C57BL/6J mice cultured in vitro were collected and divided into control group(administered normal saline),empty lentivirus transfected cell group(sh-NC group)(administered lentivirus transfection),KIF3B knockdown group(sh-KIF3B group)(administered KIF3B gene knockdown),and KIF3B knockdown plus Smoothened receptor agonist(SAG)group(sh-KIF3B+SAG group)(administered KIF3B gene knockdown followed by SAG addition),based on whether the KIF3B gene was knocked down and whether the SAG was used to activate the sonic hedgehog(Shh)signaling pathway and its downstream coreceptor Smo,with 5 rats in each group.Transmission electron microscope was used to observe the morphology and the number of autophagosomes/autolysosomes in the mEPMCs in various groups;Western blotting method was used to detect the expression levels of autophagy-related proteins Beclin-1 and p62,and the Shh signaling pathway proteins Shh and Smo in the mEPMCs in various groups.Results:The transmission electron microscope observation results showed that compared with control group,the number of autophagosomes/autolysosomes in sh-KIF3B group was significantly increased(P<0.05);compared with sh-KIF3B group,the number of autophagosomes/autolysosomes in the mEPMCs in sh-KIF3B+SAG group was significantly decreased(P<0.05).The Western blotting results showed that compared with control group,the Beclin-1 protein expression level in the mEPMCs in sh-KIF3B group was significantly increased(P<0.05),and the KIF3B,p62,Shh,and Smo protein expression levels were significantly decreased(P<0.01);compared with sh-KIF3B group,the Shh,Smo,and p62 protein expression levels in the mEPMCs in sh-KIF3B+SAG group were significantly increased(P<0.01),and the Beclin-1 protein expression level was significantly decreased(P<0.01).Conclusion:Knockdown of KIF3B gene can promote autophagy of the mEPMCs,and the mechanism may be related to its inhibition of the Shh signaling pathway.
