ObjectiveTo determine whether Jinshui Huanxian component formula Ⅱ （ECC-JHF Ⅱ） and matrix hardness interfere with the process of epithelial-mesenchymal transition （EMT） during pulmonary fibrosis by regulating integrin β₁ （ITG β₁）， and to elucidate the underlying mechanism. MethodsA pulmonary fibrosis mouse model was established by a single intratracheal instillation of bleomycin （BLM）. To observe the disease progression at various time points， the mice were sacrificed before modeling and on days 7， 14， 21， 28 and 42 after modeling for assessment of relevant indicators. To evaluate the therapeutic effect of drug intervention， the mice were given ECC-JHF Ⅱ and pirfenidone （PFD） by gavage starting on day 29 after modeling for 14 days of treatment， after which the mice were sacrificed. Pulmonary function， pathological changes， collagen deposition， lung tissue hardness and EMT markers were detected. Polyethylene glycol （PEG） composite hydrogels with different hardness were prepared in vitro using biomaterials such as eight-arm polyethylene glycol thiol （PEG-SH） and eight-arm polyethylene glycol maleimide （PEG-MAL）. Human type Ⅱ alveolar epithelial cells cultured in hard matrix culture dishes were treated with low， medium， and high doses of ECC-JHF Ⅱ （15.31， 30.63， 61.25 mg·L^-1） to observe the intervention effect of ECC-JHF Ⅱ on EMT induced by transforming growth factor beta 1 （TGF-β₁）. Human type Ⅱ alveolar epithelial cells cultured on soft （3.8 kPa） and hard （culture dishes， ~ GPa） matrices were treated with ECC-JHF Ⅱ， respectively. The mRNA and fluorescence expression levels of the epithelial marker E-cadherin （CDH1）， the mesenchymal marker N-cadherin （CDH2） and vimentin （VIM）， as well as ITG β₁， were detected by real-time quantitative polymerase chain reaction （Real-time PCR） and immunofluorescence. Western blot was used to detect the protein expression of CDH1， CDH2 and ITG β₁， and the biomechanical mechanism of ECC-JHF Ⅱ on EMT and pulmonary fibrosis was further verified by knocking down and specific activation of ITG β₁. ResultsECC-JHF Ⅱ treatment improved BLM-induced pulmonary fibrosis in mice， as evidenced by significantly increased minute ventilation （MV） and 50% expiratory flow at tidal volume （EF₅₀） （P<0.05）， and significantly increased tidal volume （TV） after treatment （P<0.01） compared with the model group. Immunohistopathological analysis revealed attenuated inflammation and alveolar injury， reduced deposition of type Ⅰ collagen （Col-Ⅰ）， and significantly decreased lung tissue stiffness （P<0.01）， thereby alleviating disease progression. The real-time PCR results showed that， compared with the model group， the ECC-JHF Ⅱ group showed increased CDH1 expression and decreased CDH2 and VIM expression in mouse lung tissues （P<0.05， P<0.01）， indicating that ECC-JHF Ⅱ inhibited the EMT process to ameliorate pulmonary fibrosis. In vitro experimental results showed that both ECC-JHF Ⅱ and matrix softening reversed the EMT phenotype switch. Specifically， compared with the hard matrix group， the cells cultured on the soft matrix exhibited significantly upregulated expression of the epithelial marker CDH1 （P<0.01） and significantly downregulated expression of the mesenchymal markers CDH2 and VIM （P<0.05）. Furthermore， ECC-JHF Ⅱ inhibited the expression of ITG β₁ both in vitro and in vivo. Knockdown and specific activation of ITG β₁ further confirmed that ITG β₁ is involved in the regulatory process by which ECC-JHF Ⅱ inhibits EMT and ameliorates pulmonary fibrosis. ConclusionECC-JHF Ⅱ and matrix softening can block the EMT process and ameliorate pulmonary fibrosis， and the underlying mechanism may be associated with the inhibition of ITG β₁-mediated mechanotransduction. This study reveals a novel mechanism of ECC-JHF Ⅱ intervention in pulmonary fibrosis from a biomechanical perspective.

Objective:To study the inhibitory effect of endothelial progenitor cells (EPCs) on aortic injury in mice with systemic lupus erythematosus (SLE) arteriosclerosis.Methods:APOE -/- mice were injected with norphytane and high fat diet to establish lupus vascular injury model. Then the mice were divided into normal control group (ND group), high fat diet group (HFD group), high fat diet+ SLE vascular injury group (HFD+ SLE group), high fat diet+ SLE vascular injury+ hydroxychloroquine treatment group (HFD+ SLE+ Hydro group), high fat diet+ SLE vascular injury+ EPCs treatment group (HFD+ SLE+ EPCs group). At the end of the experiment, urine, blood and aortic tissues of mice in each group were collected, and the content of urinary protein and the depth of serum type I interferon (IFN-Ⅰ) were detected by enzyme linked immunosorbent assay (ELISA). The activation of cyclic guanosine monophosphate synthase/interferon gene stimulating factor/type I interferon (cGAS/STING/IFN-Ⅰ) pathway, the levels of inflammatory factors, adhesion fractions and chemokines in the aorta of mice in each group were detected by immunohistochemistry and Western blotting (WB). The lipid deposition in the aorta was detected by oil red staining. Results:The results of ELISA showed that the levels of urinary protein and serum IFN-Ⅰ in HFD+ SLE group were higher than those in normal control group. EPCs treatment could reduce the levels of urinary protein and serum IFN-Ⅰ in SLE atherosclerotic mice. WB results showed that the expression of CD19, CD68, CD34, chemokine, cGAS, p-STING, phosphorylated TANK binding kinase 1 (p-TBK1), phosphorylated interferon regulatory factor 3 (p-IRF3) and IFN-Ⅰ increased in HFD+ SLE group, and hydroxychloroquine and EPCs decreased the levels of these factors. CGAS/STING/IFN-Ⅰ signal pathway is involved in the occurrence and development of atherosclerosis in SLE patients; both EPCs and hydroxychloroquine can inhibit the activation of cGAS/STING/IFN-Ⅰ signal, thus reducing atherosclerosis in SLE mice.Conclusions:cGAS/STING/IFN-Ⅰ pathway is involved in the development of SLE atherosclerosis. EPCs can inhibit the activation of cGAS/STING signal, reduce the expression and secretion of IFN-Ⅰ, and then reduce vascular inflammation and inhibit the development of SLE-related atherosclerosis.

Objective:To analyze and summarize the clinical characteristics of mpox patients, thereby to rise clinicians′ awareness of severe mpox and provide a foundation for clinical diagnosis and treatment.Methods:The clinical data were retrospectively analyzed in 41 mpox patients treated at the Beijing You′an Hospital, Capital Medical University, from June to November 2023. Patients were categorized into mild and severe cases based on clinical manifestations, and laboratory results of the two groups were compared. Statistical analysis was performed using the Mann-Whitney U test. Results:The clinical manifestations of 41 mpox patients mainly included fever, rash and lymphadenopathy. Five patients with severe mpox might develop serious complications, including bacterial pneumonia, type Ⅰ respiratory failure, fungal infections, penile or perianal dry gangrene, penile soft tissue edema, intestinal obstruction, septic shock, perianal abscess, and necrotizing fasciitis. Patients with severe mpox had significantly higher white blood cell count (WBC), neutrophil count and C-reactive protein (CRP) level compare to those with mild cases (14.60(9.92, 24.08)×10 9/L vs 6.41(5.64, 8.37)×10 9/L, 12.43(7.02, 21.15)×10 9/L vs 3.35(2.46, 5.03)×10 9/L, 108.20(56.20, 124.10) mg/L vs 16.6(6.25, 49.98) mg/L), while the albumin level and CD4 + T lymphocyte count in the severe group were significantly lower compared to the mild cases (31.80(22.90, 35.15) g/L vs 44.70(42.90, 47.40) g/L, 24.00(12.00, 81.50)/μL vs 606.00(414.50, 767.50)/μL)). All these differences were statistically significant ( U=2.81, 3.02, 2.98, 3.56 and 3.26, respectively, all P<0.01). Conclusions:In clinical practice, clinicians should be vigilant for the possibility of severe mpox if patients exhibit a significant increase of WBC and CRP, a significant decrease in CD4 + T lymphocyte count, or if they develop severe complications.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

Objective To explore the correlation between personality traits and non suicidal self injury behavior in adolescent depression patients,in order to enhance understanding of the psychological health risks of depression patients.Methods This study was conducted at the Wuhan Mental Health Center from September 2021 to September 2023.A total of 138 patients with first-onset moderate to severe adolescent depression were included.The patients were divided into a group without self injury suicidal behavior(n=25),a non suicidal self injury(NSSI)group(n=78),and an attempted suicide(SA)group(n=35).Collect general information and data on neurotic personality scores,negative life events,emotional states,and social psychological factors using the Hamilton Anxiety Scale(HAMA),Hamilton Depression Scale(HAMD-24),and other psychological assessment tools.Using statistical methods for correlation and regression analysis to study the relationship between personality traits and non suicidal self injury behavior.Results There were significant differences in personality traits such as internal and external tendencies,psychoticism,neuroticism,and concealment among the non self injurious suicide behavior group,non suicidal self injurious behavior group,and suicide behavior group.The scores of the non suicidal self injurious behavior group and suicide behavior group were generally higher than those of the non self injurious self injurious behavior group(P<0.05);There were significant differences in self injury behavior scores among these three groups,especially in the suicide behavior group,which had the highest score,but there was no significant difference in life event scores;There were significant differences in scores for anxiety,depression,childhood trauma,stressful life events,and self-esteem among the three groups.Among them,the suicide behavior group had the highest scores for anxiety,depression,childhood trauma,and stressful life events,but the lowest score for self-esteem(P<0.05);Internal and external tendencies,psychoticism,neuroticism,and concealment are significantly correlated with non suicidal self injury behavior,and multiple regression analysis results show that these factors,as well as anxiety,depression,childhood trauma,stressful life events,and self-esteem,are inde-pendent influencing factors of non suicidal self injury behavior.The best predictive threshold for internal and exter-nal tendencies is-10.5%.Conclusion This study reveals the correlation between personality traits and non sui-cidal self injury behavior in adolescent depression patients.Understanding these relationships in clinical practice and intervention strategies can help better identify high-risk groups and provide personalized mental health support.
