Crohn's disease (CD) is a chronic progressive inflammatory bowel disease. With the introduction of the "treat-to-target (T2T) " concept, the treatment goals for CD have become clearer and more specific. Traditional surgical treatment for CD typically follows a "complication-driven" approach, in which surgery is usually performed only after severe complications, such as bowel obstruction, fistulas, perforation, or cancer have occurred. The emergence of the treat-to-target strategy and the concept of disease clearance has transformed the surgical treatment of CD from a "passive rescue" model to an "active intervention" approach. Treatment goals have shifted from merely addressing complications and improving symptoms to achieving both short and long-term therapeutic objectives within the framework of treat-to-target. Achieving these goals helps to prevent CD-related complications, delay disease progression, reduce the risk of recurrence and malignancy, and improve the quality of life.

Objective To investigate the expression of EIF5A1 in intrahepatic cholangiocarcinoma cell lines and human hepatobiliary duct epithelia,and its effect on the proliferation,migration and invasion ability and Wnt/β-Catenin signaling pathway in HUCCT1 cells.Methods Western blot was used to detect the basal expression level of EIF5A1 in intrahepatic cholangiocarcinoma cell lines and human intrahepatic cholangiocarcinoma epithelial cells.Transient transfection of siRNA was used to silence the expression of EIF5A1 in intrahepatic cholangiocarcinoma cell HUCCT1.The experimental groups were divided into blank control group(Con),siRNA1 group,and siRNA2 group.The most effective siRNA was screened by Western blot.The effects of EIF5A1 silencing on the proliferation,migration and invasion ability of HUCCT1 cells were detected by CCK-8,EdU cell proliferation assay and Transwell assay.The effect of EIF5A1 silencing on the Wnt/β-Catenin signaling pathway in HUCCT1 cells was detected by Western blot.Results The results of CCK-8 and EdU cell proliferation experiments showed that the proliferation ability of HUCCT1 cells decreased after EIF5A1 silencing(P<0.05),and Transwell migration and invasion experiments showed that the migration and invasion ability of Hucct1 cells decreased after EIF5A1 silencing(P<0.05).Western blot analysis revealed decreased expression of β-Catenin,Cyclin D1,MMP-2 and Survivin in Wnt/β-Catenin signaling pathway after EIF5A1 silencing(P<0.05).Conclusion EIF5A1 may promote the proliferation,migration and invasion of intrahepatic bile duct cancer cells through Wnt/β-Catenin signaling pathway.

The Healthy China 2030 Plan set the goal of reducing premature deaths from diabetes by 30% by 2030. However, there has been a lack of assessment of premature mortality for diabetes since the action plan was issued. This study used data from the Global Burden of Disease Study 2021, calculated the premature deaths for diabetes by sex, provinces, and subtypes from 1990 to 2021. We explored the temporal trend of premature mortality using the average annual percent change (AAPC) for different sexes, provinces, and subtypes from 1990 to 2021. Furthermore, we predicted premature mortality for diabetes through 2030 for China and its provinces according to the average annual change rate from 2010 to 2021. There was a first slow upward trend in premature mortality for diabetes from 0.5% in 1990 to 0.6% in 2004, and then a decline until 2021 with premature mortality of 0.4%. By 2030, only Fujian (30.3%) will achieve the desired level of reduction, with only seven provinces meeting the target for females and none for males. There is a large range in the degree of decline between inland and coastal regions, showing obvious geographic differences, and there should be a focus on balancing medical resources.

OBJECTIVE: To investigate the efficacy of minimally invasive osteotomy with preservation of blood supply to the transversely transported bone segment in the treatment of chronic ischemic lower limb diseases using tibial transverse bone transport. METHODS: A retrospective analysis was conducted on the clinical data of 12 patients with chronic ischemic lower limb diseases who met the selection criteria and were treated between June 2016 and December 2023. The cohort included 7 males and 5 females, aged 26-87 years (mean, 61.2 years). Among them, 7 patients had diabetic foot (DF), including 2 cases complicated by arteriosclerosis obliterans (ASO), with a DF duration ranging from 1.7 to 23.0 months (mean, 9.6 months) and ulcer sizes ranging from 3.2 cm×2.4 cm to 10.0 cm×6.6 cm. Three patients had ASO with a disease duration of 1.7-23.0 months (mean, 10.4 months) and ulcer or post-amputation wound sizes ranging from 2.2 cm×2.1 cm to 12.0 cm×7.7 cm. Additionally, 2 patients with thromboangiitis obliterans (TAO) had a disease duration of 7 and 12 months, respectively. Preoperatively, the mean foot skin temperature was (27.63±0.34)℃, and the visual analogue scale (VAS) score was 8.5±0.7. All patients underwent tibial transverse bone transport using minimally invasive osteotomy while preserving the blood supply to the transported bone segment. Postoperative complications and foot ulcer healing were observed. The effectiveness of tibial transverse bone transport was evaluated by comparing preoperative and postoperative foot skin temperature, VAS scores, as well as through CT angiography (CTA). RESULTS: One DF patient with ASO was lost to follow-up, while the remaining 11 patients were followed up 10-29 months (mean, 20.5 months). One DF patient had a displaced fracture at the site of tibial transport due to trauma, which healed after plaster immobilization; 1 DF patient had a small amount of pigmentation in the skin of the donor site, but the blood circulation was good; no complication such as pin tract infection, skin necrosis, or osteomyelitis occurred in the donor site of all patients. At 2-3 weeks postoperatively, the foot skin temperature was (34.21±0.65)℃, and the VAS score was 0.3±0.1, both significantly improved compared to preoperative ones ( t=-31.578, P<0.001; t=49.000, P<0.001). Two TAO patients experienced recurrent, persistent, intolerable pain at 7-10 days postoperatively, with no reduction in ulcer size or necrotic areas; 1 underwent toe amputation, and the other required a mid-leg amputation. The remaining patients achieved complete ulcer healing, with healing time ranging from 5.1 to 9.2 weeks (mean, 6.8 weeks). CTA showed no new vascular occlusions or embolisms. X-ray films at 4 months postoperatively demonstrated proper repositioning and good healing of the transported tibial bone segment. CONCLUSION The application of minimally invasive osteotomy with preserved blood supply to the transversely transported bone segment in tibial transverse bone transport for the treatment of chronic ischemic lower limb diseases effectively minimizes extensive soft tissue dissection, reduces surgical soft tissue damage, and better maintains local blood supply. This approach lowers the risk of postoperative infection and skin necrosis while accelerating postoperative recovery.

Objective:To construct a prior based on the inherent properties of PET to accurately segment the lesion areas.Methods:A network framework for PET tumor segmentation driven by geodesic priors was proposed (geodesic network for short). Specifically, partial differential equations were constructed to characterize the geodesic distances between different regions in PET images. Tumor marker points identified by CT labeling were used as the initial conditions for the equations. To enhance the contrast between areas of lung or breast tumors and normal tissues, a smooth Heaviside function was utilized to map the geodesic distances. The network framework adopted a dual-branch architecture, using geodesic priors to assist in PET image segmentation.Results:The proposed method achieved a Dice coefficient of 94.92% in lung cancer segmentation and 90.12% in breast cancer segmentation. With the addition of geodesic priors in the Unet, the Dice coefficient for breast cancer increased by 32.37% (from 42.50% to 74.87%).Conclusion:Geodesic priors can significantly improve segmentation outcomes and enhance the generalization capability of the network.

The interaction between skeletal aging and systemic aging has emerged as a frontier in the field of aging biology research.Recent studies have indicated that bones serve not only as mechanical support organs but also as endocrine organs that regulate systemic homeostasis through bone-derived factors.This review systematically elaborates the characteristics and mechanisms of skeletal aging, including tissue structural remodeling, cellular phenotypic changes, microenvironmental disruption, and molecular network disorders, etc.In aging organisms, bones interact with other organs to form a "bone-system aging axis", thereby promoting the occurrence and development of geriatric comorbidities.Accordingly, multi-target intervention strategies targeting the "bone-system aging axis" show the potential in decelerating the progression of systemic aging.In-depth research on the characteristic changes in inter-organ communication during the aging process of the body is not only conducive to facilitating the development of more comprehensive systemic anti-aging strategies, but also provides a new perspective for treating geriatric comorbidities and achieving healthy aging.

No research considering the expression of protein post-translational crotonylation in benign prostate hyperplasia (BPH), and the correlation between crotonylation and clinical urodynamic testing parameters. 176 BPH samples collected in our hospital were stained with crotonylation pan-antibody, and the correlation between staining scores and urodynamic test parameters were analyzed. The results showed that 14.77% of BPH tissues had high levels, 40.34% had moderate levels, and 44.89% had low levels of crotonylation modification in cytoplasm. 43.75% of BPH tissue cell nuclei were stained positive, of which 12 cases showed high levels, 18 cases had medium levels, and 47 cases had low levels of crotonylation modification. The volume of BPH tissue with high-level cytoplasmic crotonylation modified [(90.15±29.88) ml] was significantly higher than that of medium-level [(52.53±28.68) ml] and low-level [(43.33±19.65) ml] tissues ( P<0.001). Parameters from urodynamics including detrusor pressure and prostate plateau area were significantly higher in the high-level crotonylation group [(63.21±36.25) cmH 2O and (2 011.2±518.7) mm·cmH 2O]than those in the medium- [(45.0±25.4) cmH 2O and (1 319.1±564.4) mm·cmH 2O] and low-level [(37.1±19.5)cmH 2O and (1 496.4±520.1)mm·cmH 2O] groups ( P<0.01). High-level crotonylation modification is related to the proliferation of BPH tissue and the urodynamic performance of patients, which could be involved in the occurrence and development of BPH.
