ObjectiveTo investigate the effects and underlying mechanisms of Shenqi Wenfei prescription （SQWF） on chronic obstructive pulmonary disease （COPD）. MethodsA rat model of COPD with lung Qi deficiency was established using lipopolysaccharide （LPS） combined with cigarette smoke. Forty-eight SD rats were randomly divided into a blank group， a model group， low-， medium-， and high-dose SQWF groups （2.835， 5.67， 11.34 g·kg^-1）， and a Yupingfeng group （1.35 g·kg^-1）. Drug administration began on day 29 after modeling and continued for 2 weeks. The general condition of the rats was observed， and the lung function in each group was assessed. Hematoxylin-eosin （HE） staining was used to observe pathological changes in lung tissue. The proportion of inflammatory cells in bronchoalveolar lavage fluid （BALF） was measured. Apoptosis in lung tissue was examined by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling （TUNEL） staining. The release level of lactate dehydrogenase （LDH） in BALF was detected by a microplate assay. Reactive oxygen species （ROS） levels in lung tissue were detected using fluorescent probes. The levels of malondialdehyde （MDA）， total superoxide dismutase （SOD）， and reduced glutathione （GSH） in BALF were measured by biochemical methods. Ultrastructural changes in lung cells were observed via transmission electron microscopy. Double immunofluorescence staining was performed to detect the expression of thioredoxin-interacting protein （TXNIP） and nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） in lung tissue. Western blot analysis was used to detect the protein expression of TXNIP， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， cysteinyl aspartate-specific protease-1 （Caspase-1）， Caspase-1 p20， gasdermin D （GSDMD）， GSDMD N-terminal active fragment （GSDMD-N）， interleukin-1β （IL-1β）， and IL-18 in lung tissue. Serum IL-1β and IL-18 levels were measured by ELISA. ResultsCompared with the blank group， the model group showed lassitude， fatigue， tachypnea， and audible phlegm sounds， and lung function significantly declined （P0.01）. Pulmonary emphysema and inflammatory cell infiltration were obvious. The level of inflammatory cells in BALF increased significantly （P0.05）. The number of TUNEL-positive cells increased （P0.01）. Levels of LDH， ROS， and MDA in BALF increased significantly （P0.01）， while GSH and SOD activities decreased significantly （P0.01）. Lung tissue cells showed irregular morphology， swollen mitochondria， disrupted cell membranes， and abundant vesicles， i.e.， pyroptotic bodies. Protein levels of TXNIP， NLRP3， ASC， Caspase-1， Caspase-1 p20， GSDMD， GSDMD-N， IL-1β， and IL-18 in lung tissue were significantly elevated （P0.01）， and serum IL-1β and IL-18 levels also increased significantly （P0.01）. Compared with the model group， each medication group showed alleviation of qi deficiency symptoms and improved lung function （P0.01）. Pulmonary emphysema and inflammatory cell infiltration were reduced. Inflammatory cell levels decreased （P0.05）. The number of TUNEL-positive cells decreased significantly （P0.01）. Levels of LDH， ROS， and MDA decreased significantly （P0.05）， while GSH and SOD activities significantly increased （P0.01）. Morphological and structural damage in lung tissue was improved to varying degrees. Protein levels of TXNIP， NLRP3， ASC， Caspase-1， Caspase-1 p20， GSDMD， GSDMD-N， IL-1β， and IL-18 in lung tissue significantly decreased （P0.01）， and serum IL-1β and IL-18 levels also decreased significantly （P0.05）. ConclusionSQWF can improve lung function and alleviate inflammatory responses in COPD rats. Its mechanism may be related to regulating the ROS/TXNIP/NLRP3 pathway and inhibiting pyroptosis.

OBJECTIVE To investigate the potential mechanism by which Juanxiao decoction improves bronchial asthma （hereinafter referred to as “asthma”） based on the nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 （NLRP3） inflammasome signaling pathway. METHODS Female SD rats were randomly assigned to normal group， model group and Juanxiao decoction low-， medium- and high-dose groups （0.36， 0.72 and 1.44 g/kg， calculated based on crude drug weight）， as well as positive control group （Dexamethasone acetate tablets， 0.2 mg/kg）， with 10 rats in each group. Except for the normal group， asthma models were established in the remaining groups via intraperitoneal injection of ovalbumin combined with aluminum hydroxide， followed by nebulized inhalation of ovalbumin. On day 14 of the experiment， rats in each group received intragastric administration of the corresponding solution or normal saline， once a day， for 7 consecutive days. Following the final administration， the following parameters were measured in each group： lung function indexes （forced vital capacity， forced expiratory volume in 0.3 second， peak expiratory flow）， serum levels of inflammatory markers （interleukin-1β， interleukin- 18）， and the percentages of inflammatory cells （lymphocytes， eosinophils， neutrophils） in bronchoalveolar lavage fluid. Histopathological changes in lung tissue were observed， and the protein and mRNA expressions of nuclear factor-kappa B （NF- κB）， NLRP3 and caspase-1 in lung tissue were detected. RESULTS Compared with the normal group， pathological changes such as alveolar wall thickening and inflammatory cell infiltration were observed in rats in the model group. All pulmonary function indicators were significantly reduced in rats in the model group and the administration groups. The levels of inflammatory markers， the percentages of inflammatory cells， and the protein and mRNA expressions of NF-κB， NLRP3 and caspase-1 were significantly elevated or up-regulated （P＜0.05）. Compared with the model group， pathological changes in rats in each dosage group of Juanxiao decoction were significantly alleviated， and all quantitative indicators showed dose-dependent improvements （P＜0.05）. CONCLUSIONS Juanxiao decoction can reduce airway inflammatory responses in asthmatic rats， alleviate lung function impairment， and improve pathological changes such as inflammatory cell infiltration. Those effects may be related to the inhibition of the NLRP3 inflammasome signaling pathway.

Objective To establish the functional constipated mouse model by compound diphenoxylate, and explore the anti-constipation effect of black garlic polysaccharide. Methods Mouse small intestine ink propulsion experiment and mouse defecation experiment were carried out respectively. The mice in each experiment were randomly divided into blank group, model group, positive group and black garlic polysaccharide （0.25, 0.5, 1 g/kg） groups. Mice in blank group and model group were given distilled water, and in positive group were given lactulose oral solution. Compound diphenoxylate （5 mg/kg） was intragastric administrated after 1 week of administration, and small intestine propulsion experiment and defecation experiment were conducted respectively. Results Compared with model group, intestinal propulsion rate of black garlic polysaccharide groups was significantly increased and first dejection time was significantly shorten, and the number, weight and fecal water content increased significantly at 6 h in middle and high dose groups. Conclusion Black garlic polysaccharide could promote intestinal propelling, shorten defecation time and increase fecal water content.

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.

ObjectiveTo investigate the target proteins directly bound by neochlorogenic acid （NA） and the molecular mechanisms that ameliorate the proliferation and inflammatory response of psoriatic keratinocytes. MethodsM5-induced HaCaT cells were used as a psoriatic keratinocyte proliferation and inflammatory cell model. The synthesized NA probe （NA-P） and NA prodrug were first evaluated for cell viability using a cell proliferation/cell counting kit-8（CCK-8）. The potency of NA and NA-P was evaluated in the safe concentration range， and the effects of 0-100 μmol·L^-1 NA and probe on M5-induced proliferation of HaCaT cells were detected using CCK-8. The effects of 20， 40， 80 μmol·L^-1 NA and 80 μmol·L^-1 NA-P on the expression of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， interleukin-23 （IL-23）， and interleukin-17A （IL-17A） inflammatory factors were detected by enzyme-linked immunosorbent assay （ELISA）， and real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to measure the effects of NA on the mRNA expression of keratin 16 （K16） in HaCaT cells， S100 calcium-binding protein A9 （S100A9）， S100 calcium-binding protein A7 （S100A7）， IL-6， IL-17A， and chemokine 1 （CXCL1）. In vitro fluorescence labeling and competition experiments using NA-P were performed， and target protein angling and analysis using pull-down experiments combined with liquid chromatography-mass spectrometry （Pull-down/LC-MS/MS） were conducted. Target validation was performed using pull-down experiments combined with protein immunoblotting （Pull down-WB）， cellular heat transfer analysis combined with protein immunoblot （CETSA-WB） experiments， and molecular docking. Finally， Real-time PCR was utilized to detect the effects of 20， 40， 80 μmol·L^-1 NA and 80 μmol·L^-1 NA-P on the mRNA expression of IL-1β， nucleotide-binding oligomeric structural domain-like receptor protein 3 （NLRP3）， apoptosis-associated speckled-like protein （ASC）， and cysteine protease-1 （Caspase-1） in HaCaT cells. Protein immunoblot （Western blot） was used to detect the effects of phosphorylated p65 （p-p65）， p65， phosphorylated human nuclear factor-κB inhibitory protein α （p-IκBα）， human nuclear factor κB inhibitory protein α （IκBα）， and heat shock protein 90 （HSP90） expression. ResultsIn the 200 μmol·L^-1 safe concentration range， HaCaT cell proliferation， increased expression of TNF-α， IL-1β， IL-23， and IL-17A inflammatory factors， and increased mRNA expression of K16， S100A9， S100A7， IL-6， IL-17A， and CXCL1 were observed in the M5 group compared with the blank group. Cell proliferation in 5-100 μmol·L^-1 NA and NA-P groups was inhibited， and the expression of TNF-α， IL-1β， IL-23， and IL-17A inflammatory factors was decreased in the NA-L， NA-M， NA-H， and NA-P-H groups. The mRNA expression of K16， S100A9， S100A7， IL-6， IL-17A， and CXCL1 was decreased （P<0.05）. High-confidence targets were screened for HSP90 protein by Pull-down/LC-MS/MS using 200 μmol·L^-1 NA competing with 100 μmol·L^-1 NA-P. Compared with that in the blank group， the mRNA expression of NLRP3， IL-1β， ASC， and Caspase-1， as well as the expression of p-p65/p65， p-IκBα/IκBα， and HSP90 protein， were increased in HaCaT cells in the M5 group （P<0.05）. Compared with that in the M5 group， the mRNA expression of NLRP3， IL-1β， ASC， and Caspase-1 of cells in the NA-L group， the NA-M group， the NA-H group， and the NA-P-H group was decreased （P<0.05）. p-p65/p65 and p-IκBα/IκBα were decreased in the NA-M and NA-H groups （P<0.05）， and there was no change in HSP90 protein. Pull down-WB showed that NA could directly target HSP90 protein， and NA binding to HSP90 protein enhanced its thermal stability. Molecular docking of NA with HSP90 family proteins HSP90AA1， HSP90B1， and HSP90AB1 all resulted in highly stable binding. ConclusionNA can inhibit the proliferation and inflammatory response of psoriatic keratinocytes by a mechanism that may be achieved by targeting HSP90 to modulate the NF-κB/NLRP3 signaling pathway.

ObjectiveTo construct an animal model of respiratory syncytial virus（RSV）-infected pneumonia suitable for preclinical studies. MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect （CPE）， and 50% tissue culture infective dose（TCID₅₀） was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group， the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor （IGF1R） mice was evaluated by measuring organ indices， peripheral blood lymphocyte percentages， pulmonary pathology and imaging， and pulmonary viral load. Additionally， ten BALB/c mice served as normal group， and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group， ribavirin group （82.5 mg·kg^-¹·d^-¹）， and high and low dose groups of Lianhua Qingwen （3.3 mg·kg^-¹·d^-¹ ， 1.65 mg·kg^-¹·d^-¹）， with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention， and the model was applied to the evaluation of anti-RSV drugs. ResultsIn the lungs of the humanized IGF1R model group， large solid and diffuse ground-glass shadows were seen， and the lung volume was significantly increased （P<0.01）. The lung index was significantly increased （P<0.01）， and both the spleen index and thymus index were significantly decreased （P<0.01）. The percentages of CD3⁺ and CD4⁺T cells were significantly decreased （P<0.05）， and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue， which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached， with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV， the expression of viral nucleic acids in the lung tissue of the mice was significantly increased， with significant differences compared with the normal group （P<0.01）. The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced， with significant differences compared with the normal group （P<0.01）. ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC， and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed， which is suitable for the evaluation of anti-RSV drugs.

ObjectiveTo explore the effects of the Tibetan medicine Sanwei Doukoutang （SWDK） on cognitive dysfunction in mice suffering from Alzheimer's disease （AD） and its related mechanism. MethodsFifty SPF 5 × FAD mice were randomly divided into model group， total ginsenoside group（0.04 g·kg^-1）， high-， medium-， and low-dose groups of SWDK （32.60， 16.30， 8.15 g·kg^-1）， with 10 mice in each group， and ten wild-type mice of the same age were used as the normal group， male and female in 1∶1. Gavage administration was performed once daily for 8 weeks. The Morris water maze test and contextual fear memory experiment were used to observe learning and memory function. Hematoxylin-eosin （HE） staining was utilized to observe the changes in the pathomorphology of brain tissue in mice. The levels of synaptophysin （SYP） and postsynaptic dense substance 95 （PSD95） in mice serum were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expression of brain-derived neurotrophic factor（BDNF） in the dentate gyrus （DG） region of mouse brain tissue was observed by immunohistochemistry （IHC）. The protein levels of BDNF， Wnt family member 3A（Wnt3a）， and β-catenin were detected in the hippocampus of mice by Western blot. ResultsCompared with the normal group of mice， the model group of mice had significantly more complex swimming routes and lower swimming speed （P<0.01）， significantly lower percentage of time spent in the target quadrant （P<0.01）， and a significantly lower percentage of freezing time （P<0.05）. The number of neurons in the hippocampal region of mice was obviously reduced and unevenly arranged. The levels of SYP and PSD95（P<0.01） in the serum of mice were reduced， and the positive expression of BDNF in the DG region of the brain tissue of mice was reduced. The levels of hippocampal BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice were obviously reduced （P<0.05， P<0.01）. Compared with the model group， the mice in the SWDK group and the total ginsenoside group had significantly shorter swimming routes， the high- and medium- dose SWDK groups significantly higher swimming speeds （P<0.01）， significantly higher percentage of time spent in the target quadrant （P<0.01）， obviously higher percentage of Freezing time （P<0.05）， and obviously more neurons in the hippocampal region of the mice with tighter arrangement. The mice had elevated levels of serum SYP （P<0.05， P<0.01）， PSD95 （P<0.01）， increased BDNF-positive cells in the DG region of brain tissue， and obviously elevated levels of BDNF， Wnt3a， and β-catenin proteins in the hippocampus of mice （P<0.05， P<0.01）. ConclusionSWDK can significantly improve the cognitive dysfunction of AD mice， and its mechanism may be related to regulating the Wnt/β-catenin signaling pathway， which promotes BDNF expression and thereby enhances synaptic plasticity， allowing neuronal signaling to be restored.

Currently， viral pneumonia （VP） presents a major challenge to global public health. Traditional Chinese medicine （TCM） prevention and treatment of VP is guided by the core concept of strengthening vital energy and eliminating pathogenic factors rather than targeting specific pathogens， alongside a holistic approach of syndrome differentiation and treatment. By summarizing the clinical syndromes of patients， the core pathogenesis was clarified to achieve individualized therapy. Animal models for disease-syndrome combination integrate the etiology and pathogenesis of VP and simulate the individualized manifestations of patients at different disease stages， providing an experimental platform for elucidating the theoretical basis of TCM in treating VP and promoting the development of effective TCM formulations. However， there are limitations in the application and promotion of disease-syndrome combination animal models due to the lack of standardization and normalization of model construction systems， which arise from diverse species selection， compound modeling methods， and multidimensional evaluation indicators. This paper systematically reviewed the recent research on animal models for disease-syndrome combination in VP from the perspective of species selection， modeling methods， evaluation indicators， and application status. Furthermore， it summarized the advantages and limitations of existing models， identifies future directions for improvement， and proposes optimization strategies. This review provides a reference for establishing standardized and normalized animal models for disease-syndrome combinations in VP， supporting the theoretical modernization of TCM in preventing and controlling emerging respiratory infectious diseases， and contributing to the development of new TCM drugs.
