Psoriasis is an incurable chronic inflammatory disease that requires new interventions. Here, we found that fibroblasts exacerbate psoriasis progression by promoting macrophage recruitment via CCL2 secretion by single-cell multi-omics analysis. The natural small molecule celastrol was screened to interfere with the secretion of CCL2 by fibroblasts and improve the psoriasis-like symptoms in both murine and cynomolgus monkey models. Mechanistically, celastrol directly bound to the low-density lipoprotein receptor-related protein 1 (LRP1) β-chain and abolished its binding to the transcription factor c-Jun in the nucleus, which in turn inhibited CCL2 production by skin fibroblasts, blocked fibroblast-macrophage crosstalk, and ameliorated psoriasis progression. Notably, fibroblast-specific LRP1 knockout mice exhibited a significant reduction in psoriasis like inflammation. Taken together, from clinical samples and combined with various mouse models, we revealed the pathogenesis of psoriasis from the perspective of fibroblast-macrophage crosstalk, and provided a foundation for LRP1 as a novel potential target for psoriasis treatment.

Objective To systematically evaluate the effect of threshold inspiratory muscle training on pulmonary rehabilitation in postoperative lung cancer patients,with a focus on exploring the difference in efficacy under different interven-tion modes.Methods Randomized controlled trials on the effect of threshold inspiratory muscle training on pulmonary rehabilitation in postoperative lung cancer patients were retrieved from PubMed,Cochrane Library,Embase,Web of Science,CNKI,Wanfang data,VIP and China Biomedical Literature Database.Meanwhile,gray literature from ProQuest and clinicaltrials.gov was searched as supplements.The retrieval period was from the establishment of each data-base to May 9,2025.Cochrane 5.1.0 was used to evaluate the quality of literature,and a meta-analysis was per-formed using RevMan 5.4.Results Twelve studies involving 701 patients were included,all of which were of moderate to high quality.Threshold inspiratory muscle training could reduce the pulmonary complications of postoperative lung cancer patients(OR=0.45,95%CI 0.29 to 0.68,P<0.001),shorten the hospital stay(MD=-1.85,95%CI-3.29 to-0.42,P=0.010),improve the inspiratory muscle strength(MD=5.84,95%CI 0.96 to 10.71,P=0.020),enhance their ex-ercise endurance(SMD=0.40,95%CI 0.10 to 0.71,P=0.010),and did not increase the risk of pulmonary air leakage(OR=0.88,95%CI 0.47 to 1.63,P=0.680).Subgroup analysis revealed that shortening of hospital stay(MD=-2.98,95%CI-5.87 to-0.09,P=0.040)and the improvement in exercise endurance(SMD=0.57,95%CI 0.14 to 1.00,P=0.009)were significant only when threshold inspiratory muscle training was combined with aerobic exercise.However,standalone threshold inspiratory muscle training showed no statistical signifi-cance in these two outcomes.Conclusion Threshold inspiratory muscle training can effectively reduce postoperative pulmonary complications and im-prove inspiratory muscle strength in postoperative lung cancer patients with good safety.Threshold inspiratory muscle training could shorten hospital stay and improve exercise endurance only when combining with aerobic exercise.

ObjectiveTo investigate the effect of porcine large intestine-processed Dahuang （Radix et Rhizoma Rhei） on defecation in constipation model mice and the possible mechanism. MethodsFifty Kunming mice were randomized to blank group （n=10） and model group （n=40）. Loperamide suspension at the dose of 8 mg/（kg·d） was given by gavage for four consecutive days to establish a model of constipation. The 24 successfully modeled mice were randomly divided into model group， processed Dahuang group， lactulose group， raw Dahuang group， with six mice in each group. Moreover， six randomly selected mice were chosen as control group. Since the fifth day， 8 mg/（kg·d） of loperamide suspension by gavage was given to the model group， processed Dahuang group， raw Dahuang group， and lactulose group； two hours later， the processed and raw Dahuang groups were administered with 0.6 g/（kg·d） of processed and raw Dahuang suspension， respectively， while the lactulose group was given 0.6 g/（kg·d） of latulose suspension， and the blank group and the model group were given 0.2 ml/10 g of distilled water by gavage， all for four days. The general condition， body weight after the last gavage， number of fecal particles within six hours， fecal wet weight， fecal water content ratio， intestinal propulsion rate and colonic histology changes by HE staining of each group were detected. ResultsThe body weight of the mice in the raw Dahuang group was significantly lighter than that in the other groups （P＜0.05 or P＜0.01）. The number of fecal particles， fecal wet weight and intestinal propulsion rate of mice significantly decreased in the model group than in the blank group （P＜0.05 or P＜0.01）. Compared to those in the model group， the number of fecal particles and fecal wet weight in the processed Dahuang group， lactulose group and raw Dahuang group significantly increased， and the fecal water content ratio in the raw Dahuang group increased as well （P＜0.05 or P＜0.01）. Compared to those in the processed Dahuang group， the number of fecal particles and fecal wet weight in the raw Dahuang group decreased， while the fecal water content ratio increased （P＜0.05 or P＜0.01）， and the fecal water content ratio in the lactulose group increased significantly （P＜0.05）. The intestinal propulsion rate in the processed Dahuang group was higher than that in the model group， lactulose group and raw Dahuang group （P＜0.05 or P＜0.01）. Histopathological analysis showed that the colonic crypts and goblet cells in the blank group were normal and clear， and the colonic muscular layer was thicker. The colonic crypts of the mice in the model group were damaged， with reduced goblet cells to varying degrees and changed colonic muscularis. In the lactulose group and raw Dahuang group， part of the crypts were broken， and the goblet cells were damaged to varying degrees， while in the processed Dahuang group， still the colonic tissue structure of the mice was relatively clear， and the colonic crypts and goblet cells were relatively normal， with thickened muscular layer of the colon. ConclusionPorcine large intestine-processed Dahuang could improve defecation in constipation model mice， and reduce the drastic purgation function of raw Dahuang， for which the mechanism may be related to the protection of colon histopathological damage.

Mitochondrial autophagy is a process to clear dysfunctional mitochondria in the cytoplasm to maintain the integrity of mitochondrial function and cell homeostasis. Mitochondrial autophagy is a complex physiological process， which can maintain the balance of mitochondrial quality and quantity， cell survival under starvation and harsh conditions， and the stability of the intracellular environment. Its molecular mechanism involves a variety of proteins. Many factors can induce mitochondrial autophagy， such as starvation， oxidative stress， hypoxia， depolarization， and other stresses. The accumulation of unfolded proteins can also induce mitochondrial autophagy. In recent years， as a research hotspot， the abnormality of mitochondrial morphology and function is closely related to the occurrence of a variety of diseases. The research on mitochondrial autophagy and the pathogenesis of clinical diseases has attracted more attention， such as tumors， cardiovascular diseases， liver diseases， nervous system diseases， and glucose metabolism disorders. It has been found that regulating mitochondrial autophagy may inspire the treatment of some diseases. Meanwhile， clinical researchers have paid more attention to traditional Chinese medicine （TCM）. As revealed by in-depth research， Chinese medicine has a certain value in regulating mitochondrial autophagy. The research on the pathogenesis of mitochondrial autophagy in related diseases and the intervention of Chinese medicine has found that there are many reports on the regulation of mitochondrial autophagy by Chinese medicine in tumors， cardiovascular diseases， and nervous system diseases. However， the mechanism of mitochondrial autophagy， the balance of mitochondrial autophagy， and the difference in the activation or inhibition of mitochondrial autophagy by Chinese medicine remain unclear. The regulation of mitochondrial autophagy has become a new research target strategy of Chinese medicine in the prevention and treatment of diseases. This paper reviewed the available literature in recent years to provide reference materials for the regulation of mitochondrial autophagy by Chinese medicine and ideas for the follow-up research of Chinese medicine in mitochondrial autophagy.

Carrier-free multi-component self-assembled nano-systems have attracted widespread attention owing to their easy preparation, high drug-loading efficiency, and excellent therapeutic efficacy. Herein, MnAs-ICG nanospike was generated by self-assembly of indocyanine green (ICG), manganese ions (Mn²⁺), and arsenate (AsO₄ ^3-) based on electrostatic and coordination interactions, effectively integrating the bimodal imaging ability of magnetic resonance imaging (MRI) and fluorescence (FL) imaging-guided synergistic therapy of photothermal/chemo/chemodynamic therapy within an "all-in-one" theranostic nano-platform. The as-prepared MnAs-ICG nanospike had a uniform size, well-defined nanospike morphology, and impressive loading capacities. The MnAs-ICG nanospike exhibited sensitive responsiveness to the acidic tumor microenvironment with morphological transformation and dimensional variability, enabling deep penetration into tumor tissue and on-demand release of functional therapeutic components. In vitro and in vivo results revealed that MnAs-ICG nanospike showed synergistic tumor-killing effect, prolonged blood circulation and increased tumor accumulation compared to their individual components, effectively resulting in synergistic therapy of photothermal/chemo/chemodynamic therapy with excellent anti-tumor effect. Taken together, this new strategy might hold great promise for rationally engineering multifunctional theranostic nano-platforms for breast cancer treatment.
