Objective To investigate the effect of Tan Ⅰ on SA-AKI in rats by mediating Wnt/β-catenin signaling pathway.Methods Sprague-Dawley rats were randomly divided into the following groups(n=8 per group,including 2 reserve animals per group):Sham,SA-AKI,SA-AKI+5 mg/kg Tan I,SA-AKI+10 mg/kg Tan I,SA-AKI+15 mg/kg Tan I(SA-AKI+Tan I),SA-AKI+salinomycin sodium(SS,Wnt signal inhibitor,SA-AKI+SS),SA-AKI+SS+Tan I,SA-AKI+laduviglusib(LG,Wnt signal activator,SA-AKI+LG),and SA-AKI+LG+Tan I.Rat SA-AKI model was induced by cecal ligation and puncture(CLP),with Tan I,SS,and LG administered via intraperitoneal injection.Hematoxylin-eosin and TUNEL staining were used to observe renal tissue pathological damage.Enzyme-linked immunosorbent assay was used to detect serum concentrations of neutrophil gelatinase-associated lipocalin(NGAL),IL-1β,IL-8,IL-6,and TNF-α.Creatinine(Cre)and blood urea nitrogen(BUN)kit were used to detect serum Cre and BUN concentrations.Western blot and immunofluorescence staining were used to detect the expression and fluorescence intensity of Wnt1,GSK3β,and β-catenin.Results Administration of Tan I at doses of 10 mg/kg and 15 mg/kg significantly attenuated renal injury in rats with SA-AKI(P<0.05),suppressed the levels of SA-AKI biomarkers NGAL,Cre,and BUN and pro-inflammatory cytokines(P<0.05),reduced apoptosis,and downregulated Wnt1 and GSK3β while upregulating β-catenin expression(P<0.05).Although Tan I at 5 mg/kg exhibited a modest protective effect against SA-AKI in rats,no statistically significant difference was observed compared to the sham group(P>0.05).SS weakened CLP-induced kidney injury and the production of inflammatory cytokines in rats(P<0.05),and LG further aggravated CLP-induced kidney injury in rats(P<0.05).Tan Ⅰ reversed the promoting effect of LG on kidney injury in SA-AKI rats(P<0.05).Conclusion Tan Ⅰ provides a protective effect on CLP-induced SA-AKI rat by inhibiting Wnt/β-catenin signaling pathway.

The feasibility and safety of intracardiac echocardiography (ICE)-guided catheter ablation for atrial fibrillation (AF) using a minimal/zero-fluoroscopy approach have recently been reported. This approach helps to reduce ionizing radiation exposure and orthopedic complications resulting from using lead aprons. The objectives of this planned prospective, multicenter randomized controlled trial (RCT) (paroxysmal AF (PAF)-ICE trial; ChiCTR2000033624) are to evaluate the efficacy and safety of ICE-guided minimal-fluoroscopy ablation in patients with PAF and the impact on occupational hazards among lab staff.Patients will be randomized in a 1:1 ratio to 2 groups: minimal fluoroscopy group ( n = 216) and traditional approach group ( n = 216). In the minimal fluoroscopy group, an ICE catheter will be used for geometry/anatomic construction, transseptal puncture, catheter tracking, and effusion monitoring. Pulmonary vein isolation (PVI) will be performed using an open-irrigated radiofrequency SmartTouch Surround Flow or SmartTouch catheter (Biosense Webster, Diamond Bar, California, USA), and confirmed by a multipolar Lasso or PentaRay catheter (Biosense Webster). In the traditional approach group, an ICE catheter will not be used. Transseptal puncture will be performed under fluoroscopic guidance, with all geometries constructed by mapping the catheters. The primary efficacy endpoint is freedom from AF recurrence (without antiarrhythmic medications) at 12 months after ablation. Other endpoints include duration of lead apron use, measures of intra-procedural efficiency, and peri-procedural complications. This RCT will evaluate the efficacy and safety of ICE-guided minimal-fluoroscopy ablation in patients with PAF, also evaluate the benefits to lab staff (regarding reducing occupational hazards) related to this "minimal/zero-fluoroscopy" and "leadless" mode.

OBJECTIVE: To investigate the anti-inflammatory effect and mechanisms of interleukin-35 (IL-35) in inflammatory bowel disease. METHODS: BALB/c mice were divided into three groups with 10 mice in each group:control group, model group (oral administration of 4% glucan sodium sulfate for 7 d) and IL-35-treated group (oral administration of 4% glucan sodium sulfate for 7 d, intraperitoneal injection of 2 μg IL-35 at d2-5). Disease activity index (DAI) was scored every day. After 7 d, the mice were sacrificed, and the serum and intestinal tissue samples were collected. The gross morphology of the colon was observed; HE staining was used to observe the pathological changes of colon tissue; flow cytometry was employed to detect the change of macrophage polarization ratio in colon tissue; the mRNA expression levels of cytokines IL-6, TNF-α, IFN-γ, IL-10 and SHIP1 in colon tissue were determined by real-time quantitative RT-PCR; the expression and distribution of SHIP1 in colon tissue was measured by immunohistochemistry; Western blotting was adopted to detect the expression level of SHIP1 protein in colonic intestinal tissues of each group. RESULTS: The DAI scores of the mice in the model group were higher than those in the control group, while the DAI scores in the IL-35-treated group were lower than those in the model group (all <0.01). Compared with the control group, the colon length was significantly shortened in the model group (<0.05), while the colon length of the IL-35-treated group had an increasing trend compared with the model group, but the difference was not statistically significant (>0.05). Compared with the model group, microscopic inflammatory infiltration score was decreased and microscopic crypt destruction and score was significantly lower in IL-35-treated group (all <0.05). The relative expression of proinflammatory cytokines IL-6, TNF-α and IFN-γ in the colon tissue of IL-35-treated group was decreased compared with the model group, while the relative expression of IL-10 mRNA was higher than that of the model group (all <0.05). Compared with the control group, the proportion of M1 macrophages in the model group increased (<0.05), while the proportion of M1 macrophages in the IL-35-treated group was lower than that in the model group (<0.05). The relative expression of SHIP1 mRNA and protein in the colon tissue of IL-35-treated group was higher than that in the model group (all <0.05). CONCLUSIONS IL-35 can inhibit the polarization of M1 macrophages and regulate inflammatory cytokines to promote anti-inflammatory effect on mice with colitis.
