Wnt/β-catenin signaling pathway plays an important role in the initiation and progression of colorectal cancer. The key to its carcinogenicity is related to the inhibition of β-catenin degradation, and the subsequent cytoplasmic accumulation and nuclear translocation of β-catenin, which activates the transcription of downstream target genes such as coding region instability determinant-binding protein (CRD-BP). In cancercells ,the expression of CRD-BP mediates the stabilization of β-Trcp, which in normal cells regulates the degradation of β-catenin. The activation of Wnt/β-catenin signaling pathway, overexpression of β-catenin and CRDBP, and the upregulation of β-Trcp by CRD-BP play important roles in the initiation, progression, and metastasis of colorectal cancer.

Objective:To explore the curative effect of network platform transitional nursing in the rehabilitation of schizophrenic patients.Methods:Using convenient sampling method, a total of 87 patients with schizophrenia who were admitted to Departmentof Psychiatry in the Affiliated Kangning Hospital of Wenzhou Medical Universityfrom February 2018 to January 2019 were selected as the research objects. According to the random number table method, they were divided into the control group (44 cases) and the observation group (43 cases) .The control group was given routine nursing intervention while the observation group was given network platform transitional nursing based on the control group. Before and after the intervention, the psychiatric symptoms of patients in the two groups were evaluated by Brief Psychiatric Rating Scale, medication compliance was evaluated by Medication Adherence Scaleand personal and social function and family function were evaluated by Personal and Social Performance Scale and Family Function Assessment Scale.Results:After 6 months of intervention, the scores of Brief Psychiatric Rating Scale and Medication Adherence Scale in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) .The scores of Personal and Social Performance Scale and Family Function Assessment Scale in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:In the rehabilitation treatment of schizophrenia, the implementation of network platform of transitional nursing can improve medication compliance of patients, improve their clinical mental symptoms, and finally improve their personal and social functions and family functions.

Objective:To analyze plaque characteristics of non-culprit coronary lesions with cholesterol crystals in patients with acute myocardial infarction(AMI) by using optical coherence tomography(OCT). We also investigated the potential association between cholesterol crystals with plaque rupture and healed plaque at non-culprit segment.Methods:This study was a retrospective cohort study. Between January 2017 and December 2017, patients with AMI who underwent 3-vessel OCT imaging were included in this study. Patients were divided into two groups according to the presence or absence of cholesterol crystals at the non-culprit lesions. All patients underwent coronary angiography and OCT examination, and non-culprit plaque characteristics were compared between the two groups. The generalized estimating equation log-binomial multirariate regression model was used to assess the relationship between non-culprit lesions with cholesterol crystals and plaque rupture and plaque healing. The follow-up data collection ended in October 2023. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the cumulative incidence of major adverse cardiovascular events between the two groups.Results:A total of 173 AMI patients were included (aged (56.8±11.6) years; 124 men (71.7%)). Among 710 non-culprit lesions identified by OCT, there were 102 (14.4%) in cholesterol crystals group and 608 (85.6%) in non-cholesterol crystals group. Compared with non-culprit lesions without cholesterol crystals, those with cholesterol crystals had smaller minimum lumen diameter, severer diameter stenosis, and longer lesion length (all P<0.01). The prevalence of plaque rupture (17.6% (18/102) vs. 4.9% (30/608), P=0.001) and thin-cap fibroatheroma (31.4% (32/102) vs. 11.5% (70/608), P<0.01) was higher in the cholesterol crystals groups than in the non-cholesterol crystals group. In addition, vulnerable plaque characteristics such as (44.1% (45/102) vs. 25.8% (157/608), P<0.01), macrophages were more frequently observed in non-culprit lesions with cholesterol crystals. The generalized estimating equation log-binomial multivariate regression analyses showed that non-culprit cholesterol crystals were positively correlated with healed plaque ( OR=1.583, 95% CI: 1.004-2.495, P=0.048). Conversely, cholesterol crystals were not associated with plaque rupture ( OR=1.632, 95% CI: 0.745-3.576, P=0.221). The follow-up time was 2 142 (1 880, 2 198) days. Non-culprit cholesterol crystals were not related to the major adverse cardiovascular events in patients with AMI (log-rank P=0.558). Conclusions:Among AMI patients, non-culprit lesions with cholesterol crystals presented with severer luminal stenosis and increased plaque vulnerability. The presence of non-culprit cholesterol crystals was associated with rather than plaque rupture.
