Objective: To explore the application effect of a guided self help intervention based on dialectical behavior therapy (DBT) to address non suicidal self injury (NSSI) behavior among college students, so as to provide a reference for reducing the occurrence of NSSI behavior in this population. Methods: A total of 106 college students with NSSI admitted to the Department of Child and Adolescent Psychology, the Second Affiliated Hospital of Jining Medical University from January 2021 to January 2023 were selected and divided into an observation group and a control group, with 53 cases in each group, using a random number table method. The control group received routine medication treatment and psychological intervention, while the observation group, on the basis of the interventions provided to the control group, implemented dialectical behavior therapy based guided self help. The approach combines group activities, individual counseling, and selfdirected learning, covering four core modules: mindfulness training, distress tolerance, interpersonal effectiveness, and emotion regulation. Meanwhile, data collection, skill check ins, and personalized recommendation pushes were conducted through a WeChat. Both groups were intervented for 12 weeks. Before the intervention and after the intervention, the Adolescent Non suicidal Self injury Behavior Questionnaire, Ottawa Self injury Inventory (OSI), and Barratt Impulsiveness Scale (BIS) were used to evaluate the patients, and the levels of serum neurotransmitters were detected. The χ 2 test, t test, and Cochran s Q test were used for data comparison and analysis. Results: The incidence rates of NSSI in the observation group after 3, 6, and 12 weeks of intervention were 47.17%, 16.98%, and 5.66%, respectively, all lower than those in the control group (67.92%, 35.85%, 20.75%) ( χ 2=4.67, 4.85, 5.27,all P <0.05). After 12 weeks of intervention, in the NSSI Behavior Questionnaire, the total score of the observation group was (17.94±2.69) points, which was lower than that of the control group (23.04±5.11) points; in the Function Questionnaire, the total score of the observation group was (53.24±8.94) points, which was higher than that of the control group (47.74±8.00) points（both P ＜0.05）. In terms of the OSI, the total score of the observation group was (4.49±0.62) points, lower than that of the control group (6.25±0.81) points;in the BIS, the total score of the observation group was (80.76±7.94) points, lower than that of the control group (87.74±9.34) points，and the differences between groups were statistically significant(both P<0.05). After the intervention, the level of 5-hydroxytryptamine in the observation group was (67.93±5.42) ng/mL, higher than (44.72±5.54) ng/mL of the control group; the levels of substance P and cortisol in the observation group were (35.82±4.47) ng/L and (75.64±8.02) μg/L, respectively, both lower than (48.14±5.32) ng/L and (94.53±10.78) μg/L of the control group, and the differences were statistically significant (all P <0.05). Conclusion The guided self help intervention based on DBT is helpful for reducing NSSI behavior among college students.

Objective:To explore the protective effect of sesquiterpene lactones of Eupatorium lindleyanum DC.(SLEL)on lipopolysac-charide(LPS)-induced acute lung injury(ALI)in rats using metabolomics.Methods:Forty-eight male SD rats were randomly divided into a blank control group(CG),a model control group(MG),low-,medium-,and high-dose SLEL groups(50,100,and 200 mg/kg),and a positive control group(dexamethasone acetate tablets,5 mg/kg).CG and MG groups were given phosphate-buffered saline.All groups received intragastric administration at a dose volume of 10 mL/kg once a day for 7 consecutive days.One hour after the last ad-ministration,LPS(5 mg/kg)was instilled into the trachea of all groups except the CG group to establish the ALI rat model.Twenty-four hours after model establishment,blood was collected from the abdominal aorta and bronchoalveolar lavage fluid(BALF)was col-lected from the left lung.The total number of inflammatory cells,neutrophils,lymphocytes,and eosinophils in BALF was counted by Wright-Giemsa staining.The levels of interleukin-18(IL-18)and interferon-γ(IFN-γ)in serum and BALF were measured by enzyme-linked immunosorbent assay.The pathological changes of lung tissue were observed using hematoxylin-eosin staining.The ex-pression levels of tight junction protein-1(ZO-1)and occludin in lung tissue were determined by Western blot.The mRNA expression levels of IL-18,IFN-γ,ZO-1,and occludin in the lung were measured by real-time fluorescence quantitative PCR.Non-targeted me-tabolomics analysis of serum and lung tissue was performed using ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry.Results:Compared with the MG group,all SLEL groups had significantly reduced wet/dry weight ratio of lung tissue,lung coefficient,and total number of inflammatory cells,neutrophils,lymphocytes,and eosinophils in BALF.SLEL signifi-cantly decreased the levels of IL-18 and IFN-γ in serum and BALF and the mRNA expression of IL-18 and IFN-γ in lung tissue,and significantly promoted the protein and mRNA expression of ZO-1 and occludin.Under light microscopy,the degree of lung tissue edema,alveolar hemorrhage,and inflammatory cell infiltration were significantly reduced,indicating a certain protective effect on ALI rats.The results of non-targeted metabolomics studies showed that there were 91 and 33 significantly different metabolites in the serum and lung tissue of rats treated with SLEL,respectively.Among them,the main differential metabolites in the serum were sphingosine,L-lactic acid,nicotinic acid,D-nucleotide,and mevalonate-5P,while the main differential metabolites in the lung tissue were tauro-cholic acid.This suggests that SLEL may mainly affect the metabolic pathways of sphingolipids,pyruvate,nicotinic acid,nicotinamide,and tryptophan in the serum and the metabolic pathways of taurine and hypotaurine in the lung tissue to improve ALI.Conclusion:SLEL has a significant protective effect on rats against LPS-induced ALI,and its mechanism of action may be related to the inhibition of inflammatory factors,improvement of lung barrier function,and regulation of related metabolic pathways.

Sinopodophyllum hexandruma is a traditional Chinese medicine in China,which is mostly distributed in Gansu,Shaanxi,Sichuan,Qinghai,Yunnan and Xizang,etc.In recent years,with the gradual deepening of the research on the chemical composition and pharmacology-toxicology of Sinopodophyllum hexandruma,its antitumour and antiviral pharmacodynamic evaluation has increasingly become a research hotspot in the industry.Based on the chemical structure,pharmacological properties and the theoretical basis of quality markers(Q-markers),this paper presents an in-depth literature review and analysis of the chemical composition,pharmacological activities and Q-markers of Sinopodophyllum hexandruma,and systematically explores and predicts the Q-markers of Sinopodophyllum hexandruma.It is proposed that Podophyllotoxin,picropodophyllotoxin,podophyllotoxinone,quercetin,kaempferol,quercetin-3-O-β-glucoside can be used as the Q-marker of Sinopodophyllum hexandruma.In the later stage,these index components can be selected to control the whole quality of Sinopodophyllum hexandrum,and provide some data support and theoretical reference for the quality evaluation of Sinopodophyllum hexandrum.

The female reproductive system is essential for sustaining reproductive endocrine homeostasis,however,its vulnerability to various endogenous and exogenous insults,including pathological conditions,pharmacological agents,genetic predispositions,and environmental factors,often results in compromised fertility.The existing protective approaches(including surgical interventions,hormonal replacement therapies,and assisted reproductive techniques)are constrained by several limitations,such as adverse therapeutic effects,technical complexities,and their incapacity to reverse ovarian senescence.Artemisinin and its derivatives(ARTs),characterized by their unique endoperoxide bridge configuration,have exhibited outstanding therapeutic performance across multiple domains including malaria treatment,anticancer therapy,inflammation modulation,and parasitic infection control.Emerging research has identified their novel protective capabilities against various reproductive system pathologies.This comprehensive review systematically elucidates the molecular mechanisms underlying artemisinin-based interventions in reproductive pathologies and evaluates their clinical translation prospects,thereby proposing innovative strategies for the development of next-generation fertility-protective agents with enhanced safety and efficacy profiles.
