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 develop a deep learning model based on 3D super-resolution reconstruction technology and to analyze its feasibility and effectiveness in predicting paraglottic space invasion in hypopharyngeal cancer.Methods:A retrospective study was conducted involving 382 patients with hypopharyngeal squamous cell carcinoma treated at Qilu Hospital of Shandong University between January 2014 and December 2020. The cohort included 364 males and 18 females, with a mean age of 62±7 years. Patients were divided into a training set ( n=300) and a test set ( n=82) based on enrollment time. A generative adversarial network was used to perform 3D super-resolution reconstruction on contrast-enhanced CT images, improving spatial resolution by 16 times. A 2.5D deep learning strategy was employed to construct Resnet-NR and Resnet-SR models based on conventional and super-resolution images, respectively, to predict whether the paraglottic space was invaded. Model performance was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC). A multi-reader multi-case study was conducted to assess the impact of the artificial intelligence (AI) model on clinicians′ diagnostic capabilities. Results:The super-resolution model Resnet-SR achieved the highest accuracy in both the training set (AUC=0.87, 95% CI: 0.84-0.90) and the test set (AUC=0.88, 95% CI: 0.81-0.96), significantly outperforming traditional clinical indicators (T stage, N stage, tumor diameter, and pathological differentiation degree) (AUC range: 0.55-0.70, all P<0.05). In comparison, the conventional-resolution model Resnet-NR achieved AUCs of 0.81 (95% CI: 0.77-0.84, P=0.005) and 0.80 (95% CI: 0.71-0.89, P=0.184) in the training and test sets, respectively. Using Resnet-SR to assist clinical decision-making improved the diagnostic accuracy of junior physicians (AUC=0.793 without AI assistance vs. AUC=0.871 with AI assistance, P=0.012) and significantly reduced diagnosis time for clinicians of all experience levels (86.5 s without AI assistance vs. 82.5 s with AI assistance, t=2.01, P=0.032). Conclusion:This study successfully develops a deep learning model based on 3D super-resolution reconstruction technology, which can assist in preoperative prediction of paraglottic space invasion in hypopharyngeal cancer. The AI-assisted tool improves diagnostic accuracy for junior physicians and enhances diagnostic efficiency for clinicians across all experience levels.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

Primary biliary cholangitis （PBC） is a chronic progressive autoimmune liver disease that often progresses to liver fibrosis and even liver cirrhosis. This article summarizes and reviews the research advances in the combined use of traditional Chinese medicine （TCM） and ursodeoxycholic acid in the treatment of PBC-related liver fibrosis. Various studies have shown that integrated traditional Chinese and Western medicine therapy can improve serum fibrosis markers， noninvasive liver fibrosis scores， and liver stiffness measurement in PBC patients with liver fibrosis， with a relatively good safety profile and a potential to delay or even reverse the progression of PBC-related liver fibrosis. However， current evidence is mainly derived from small-scale or short-term clinical observational studies， and in the future， large-scale high-quality randomized controlled trials and long-term follow-up studies are needed in combination with modern scientific technologies to explore underlying mechanisms， thereby further validating its efficacy and promoting the establishment of an evidence-based precise diagnosis and treatment system based on integrated traditional Chinese and Western medicine therapies. Through in-depth research， TCM is expected to play a more important role in the treatment of PBC-related liver fibrosis.

Background: Inhalation-based combination therapy has gained increasing attention for local treatments. However, a key challenge remains in ensuring the sustained pulmonary release of multiple active ingredients, particularly in traditional Chinese medicine (TCM) formulations. Objective: This study investigates a novel PulmoSphere-based inhalable carrier designed for the sustained pulmonary release of multiple active ingredients, using Shuang-Huang-Lian as a model TCM formulation containing three chemical markers. Materials and methods: The carrier was developed using PulmoSphere technology, incorporating phospholipid complexes of the chemical markers and hyaluronic acid (HA) into spray-dried microparticles. The aerodynamic properties, release characteristics, pulmonary distribution, and anti-inflammatory efficacy of different formulations were evaluated in vitro and in mice. Results: The microparticles retained the excellent aerodynamic properties of conventional PulmoSphere particles, with a mass median aerodynamic diameter of approximately 3.1 μm and a fine particle fraction of approximately 55%. Compared to free Shuang-Huang-Lian or phospholipid complex-loaded PulmoSphere particles, the HA-containing particles prolonged the retention of chemical markers in the lung epithelial lining fluid, demonstrating sustained release in vivo. Additionally, the HA-containing formulation enhanced the exposure of the three chemical markers to immune cells and lung tissues, leading to improved and prolonged anti-inflammatory effects, even at decreased doses. Conclusion: This novel inhalable particle system represents a promising approach for sustained pulmonary co-delivery of multiple active ingredients, offering enhanced and extended local therapeutic efficacy.

Objective:To examine the longitudinal relationships between perceived social support,life satis-faction and acceptance by others among relocated residents for poverty alleviation.Methods:A two-wave longitudi-nal survey was conducted with 383 relocated residents from 39 resettlement communities in Guizhou Province,with a six-month interval.Participants completed the Perceived Social Support Scale(PSSS),the Acceptance by Others Scale of the Acceptance of others Scale(AOS),and the Satisfaction With Life Scale(SWLS).Results:T1 PSSS scores positively predicted T2 acceptance by others scores(β=0.20,P＜0.001).T2 acceptance by others scores positively predicted T2 SMLS scores(β=0.45,P＜0.001).Perceived acceptance by others fully mediated the lon-gitudinal relationship between perceived social support and life satisfaction(effect=0.09,95％CI:0.03-0.18).Conclusion:Perceived social support predicts life satisfaction of relocated residents for poverty alleviation through perceived acceptance by others.

Objective:To explore the feasibility and safety of laparoscopic combined with colonoscopic transanal total mesorectal resection (laparoscopic combined with colonoscopic taTME) in the treatment of rectal cancer.Methods:The descriptive case series analysis method was adopted. From October 2023 to February 2024, the Department of Colorectal Surgery of Li Huili Hospital, Ningbo Medical Center, performed laparoscopic combined with colonoscopic taTME on 8 patients with rectal cancer. Among the 8 patients, there were 5 males and 3 females, aged from 56 to 74 years old, with a body mass index (BMI) of 20.3-26.7 kg/m2. All patients were pathologically diagnosed with rectal adenocarcinoma. The long diameter of the tumors was 2.0-6.5 cm, the lower edge of the tumors was 3-5 cm away from the anal verge. In terms of tumor TNM staging, there were 2 cases in stage I, 3 cases in stage II, and 3 cases in stage III. The surgical conditions, postoperative curative effects, and the occurrence of complications were observed.Results:All 8 patients successfully completed laparoscopic combined with colonscopic taTME, and there was no conversion to laparotomy. The operative time was 260 to 335 minutes, the intraoperative blood loss was 50 to 100 milliliters, and the distance from the tumor to the anal margin was 0.8 to 2.0 centimeters. All patients in the group underwent protective end ileostomy, and none of them underwent permanent enterostomy. Specimens were removed from the right lower abdomen in 7 cases and through the anus in 1 case. There was no residual cancer cells at the pathological resection margins postoperatively. All patients ambulated on the first day after the operation, and began to eat on the 2nd to 3rd day after the operation. Anastomotic leakage occurred in 1 patient after the operation, and the condition improved after conservative treatment. The length of hospital stay was 21 days. The other 7 patients were discharged from the hospital 8 to 12 days after the operation. Two patients completed the ileostomy closure surgery 3 months after the operation and recovered well. The patients were followed up until April 2024, during which there were no cases of tumor recurrence or death.Conclusion:For appropriate cases, laparoscopic combined with colonoscopic taTME is safe and feasible.
