ObjectiveTo reveal the effects of overexpression and knockdown of CDH18 gene on cervical cancer proliferation and migration levels through the Wnt/β-catenin signaling pathway in cervical cancer cells. MethodsA comprehensive analysis of CDH18-interacting molecules was performed via the bioinformatics STRING database （http：//cn.string-db.org）. Molecular docking between Wnt/β-catenin inhibitor XAV939 and β-catenin was performed using the bioinformatics tool AutoDock （http：//autodock.scripps.edu）. The effect of CDH18 on β-catenin subcellular distribution was detected by laser confocal microscopy. EdU assay， wound healing assay and Transwell assay were used to detect the effects of CDH18 gene overexpression， CDH18 gene knockdown and the XAV939 on cell proliferation and migration. Western blot was performed to measure the expression levels of Wnt/β-catenin pathway-related molecules， including β-catenin， transcription factor 4 （TCF4）， and cellular myelocytomatosis oncogene （c-Myc）， following CDH18 gene overexpression， CDH18 gene knockdown， or XAV939 treatment. ResultsIn SiHa and HeLa cells， CDH18 gene overexpression significantly increased the protein expression levels of β-catenin， TCF4 and c-Myc， decreased the protein expression of GSK-3β， and enhanced cell proliferation and migration， with statistically significant differences （P<0.05）. Conversely， CDH18 gene knockdown significantly reduced the protein expression of β-catenin， TCF4 and c-Myc， elevated GSK-3β expression， and suppressed cell proliferation and migration （P<0.05）.Treatment with XAV939 in SiHa and HeLa cells downregulated β-catenin， TCF4 and c-Myc， upregulated GSK-3β， and inhibited cell proliferation and migration， with significant differences （P<0.05）. ConclusionCDH18 promotes the proliferation and migration of cervical cancer cells via the Wnt/β-catenin signaling pathway.

Objective:To compare the anticoagulant efficacy and safety between argatroban and heparin in patients with liver failure complicated with hepatic encephalopathy undergoing artificial liver treatment.Methods:A total of 207 patients with liver failure complicated with hepatic encephalopathy who received artificial liver treatment in the intensive care unit (ICU) of Wuxi No.5 People′s Hospital from January 2021 to October 2024 were enrolled, including 105 cases in the argatroban group and 102 cases in the heparin group. Changes in coagulation function, hemoglobin (Hb), platelet (PLT) count, and model for end-stage liver disease (MELD) score before and after artificial liver treatment were compared between the two groups. The formation of deep vein thrombosis in the lower extremities, coagulation in the extracorporeal circulation circuit and plasma separator, bleeding at the deep venous catheter site were compared between the two groups. The 28-day survival outcome of the patient were recorded. Two independent sample t-test, rank sum test, and chi-square test were used for statistical comparisons, and the Kaplan-Meier method and log-rank test were used to analyze the survival rate of patients. Results:There were no statistically significant differences in activated partial thromboplastin (APTT), international normalized ratio (INR), Hb and PLT count before and after artificial liver treatment in the argatroban group ( Z=-1.74, -1.80, -1.26 and -0.52, respectively, all P>0.05), while the MELD score after treatment was lower than that before treatment and the difference was statistically significant ( t=6.49, P<0.001). After artificial liver treatment, the APTT in the argatroban group was 47.10(42.65, 51.90) s, which was shorter than that in the heparin group (56.05(50.02, 63.00) s). The INR, Hb, and PLT count in the argatroban group were 2.00(1.65, 2.54), 98.00(88.00, 112.00) g/L, and 92.00(75.50, 106.00)×10 9/L, respectively, which were all higher than those in the heparin group, which were 1.56(1.22, 1.93) g/L, 90.50(80.00, 104.75) g/L, and 74.00(64.75, 99.50)×10 9/L, respectively. The differences were all statistically significant ( Z=-7.16, -5.28, -3.05 and -3.32, respectively, all P<0.05). There was no statistically significant difference in MELD scores between the two groups ( P=0.250). The incidence of coagulation in the extracorporeal circulation circuit and plasma separator and bleeding at the deep venous catheter site in the argatroban group was 5.71%(6/105) and 1.90%(2/105), respectively, which were both lower than those in the heparin group (14.71%(15/102) and 9.80%(10/102), respectively). The differences were both statistically significant ( χ2=4.59 and 5.91, respectively, both P<0.05). At the end of the 28-day follow-up, the mortality rates in the argatroban group and the heparin group were 22.9%(24/105) and 34.3%(35/102), respectively, and the difference was not statistically significant ( χ2=3.33, P=0.068). There was no statistically significant difference in the 28-day survival rate between the argatroban group and the heparin group ( χ2=2.09, P>0.05). Conclusions:Argatroban has a relatively minor impact on PLT count and Hb when it is used in artificial liver treatment for patients with liver failure complicated with hepatic encephalopathy. The incidence of coagulation in extracorporeal circulation circuits and plasma separators is low, and the risk of bleeding at the deep venous catheters is low. Argatroban is highly safe, which provides a new anticoagulation option for patients with a high risk of bleeding.

Objective:To investigate the current status of occupational stress among electronic manufacturing workers in Qingdao and analyze its effect on depressive symptoms and anxiety symptoms.Methods:From July to September 2022, a cluster random sampling method was employed to select frontline workers from 14 electronic manufacturing enterprises in Qingdao as the study subjects. A total of 1134 questionnaires were distributed, with 1000 valid questionnaires collected, yielding an effective response rate of 88.18%. The Core Occupational Stress Scale (COSS), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) were adopted to assess occupational stress, depressive symptoms, and anxiety symptoms, respectively. Binary logistic regression was employed to analyze influencing factors of occupational stress and its effects on depressive and anxiety symptoms.Results:The detection rates of occupational stress, depressive symptoms, and anxiety symptoms were 15.1% (15/1000), 7.9% (79/1000), and 13.8% (138/1000), respectively. The influencing factor analysis of occupational stress revealed that female gender ( OR=0.621, 95% CI: 0.434-0.890) and weekly working hours of 45-48 hours ( OR=0.537, 95% CI: 0.309-0.935) were protective factors ( P<0.05), while weekly working hours ≥55 hours ( OR=2.176, 95% CI: 1.290-3.670) and shift work ( OR=2.038, 95% CI: 1.412-2.940) were risk factors ( P<0.05). Spearman correlation analysis showed that the COSS score was positively related with the PHQ-9 score and the GAD-7 score ( rs=0.438, 0.289, P<0.01). Workers judged with occupational stress had 3.596 times (95% CI: 2.181-5.931, P<0.001) and 3.121 times (95% CI: 2.046-4.761, P<0.001) higher risks of detecting depressive and anxiety symptoms compared to those without occupational stress. Conclusion:Electronic manufacturing workers in Qingdao experience a certain level of occupational stress, which may increase the risk of developing depressive and anxiety symptoms. Enterprises should implement appropriate interventions to promote workers' mental health.

Objective:To investigate whether the highly expressed chemokine ligand 17(CCL17)in cervical cancer(CC)pro-motes the progression of CC through M2 macrophage polarization.Methods:The effect of CCL17 on the expression of IL-27 in CC cell line was detected by flow cytometry and ELISA.The effects of CCL17 and IL-27 on proliferation and differentiation of U937 cells were analyzed.The co-culture model of macrophages and CC cells were established to detect the effects of CCL17 on the proliferation of U937 and CC cells.Results:The CC cells secreted significantly higher levels of IL-27 after stimulation with CCL17.In addition,IL-27 but not CCL17 significantly upregulated interleukin 27 receptor(IL-27R,consisted of WSX-1 and GP130)on U937 cells.IL-27 de-rived from CC cells can promote the proliferation of U937 cells and induce the polarization of M2 macrophages.In the co-culture sys-tem,the level of IL-27 secreted by CC cells stimulated by CCL17 was significantly increased,and both CCL17 and IL-27 promoted the proliferation of CC and U937 cells,and the effect of CCL17 was partially reversed by αIL-27.Conclusion:CCL17 promotes the proliferation of macrophages and induces M2 polarization by stimulating CC cells to secrete IL-27,thereby enhancing the crosstalk be-tween CC cells and macrophages.Eventually,CCL17 participates in the malignant evolution of CC.
