Knowledge,attitude,and practice of monitoring early gastric cancer after endoscopic submucosal dissection

BACKGROUND Early gastric cancer(EGC)is typically treated with endoscopic submucosal dissection(ESD).However,recurrence may occur after ESD,requiring surveillance.AIM To examine the knowledge,attitude,and practice(KAP)of EGC survivors following ESD regarding gastric cancer recurrence.METHODS This cross-sectional study was conducted between June 1,2022 and October 1,2022 in Zhejiang,China.A total of 400 EGC survivors who underwent ESD at the Affiliated Jinhua Hospital,Zhejiang University School of Medicine participated in this study.A self-administered questionnaire was developed to assess KAP monitoring gastric cancer after ESD.RESULTS The average scores for KAP were 3.34,23.76,and 5.75 out of 5,30,and 11,respectively.Pearson correlation analysis revealed positive and significant correlations between knowledge and attitude,knowledge and practice,and attitude and practice(r=0.405,0.511,and 0.458,respectively;all P<0.001).Multivariate logistic regression analysis showed that knowledge,attitude,13-24 mo since the last ESD(vs≤12 mo since the last ESD),and≥25 mo since the last ESD(vs≤12 mo since the last ESD)were independent predictors of proactive practice(odds ratio=1.916,1.253,3.296,and 5.768,respectively,all P<0.0001).CONCLUSION EGC survivors showed inadequate knowledge,positive attitude,and poor practices in monitoring recurrences after ESD.Adequate knowledge,positive attitude,and a longer time since the last ESD were associated with practice.

Cyclin Dlb Splice Variant Promotes αvβ3-mediated EMT Induced by LPS in Breast Cancer Cells

Epithelial-to-mesenchymal transition （EMT） plays a critical role in cancer metastasis, and is relevant to the inflammatory microenvironment. Lipopolysaccharide （LPS）, a cell wall constituent of gram-negative bacteria, has been reported to induce EMT of cancer cells through TLR4 signal. We previously reported that LPS promoted metastasis of mesenchymallike breast cancer cells with high expression of cyclin Dlb. However, the role of cyclin Dlb in LPS-induced EMT has not been fully elucidated. In the present study, we described that cyclin Dlb augmented EMT induced by LPS in MCF-7 breast cancer cells. Cyclin Dlb markedly amplified integrin αvβ3 expression, which was further up-regulated under LPS stimulation. Our results showed ectopic expression of cyclin Dlb promoted invasiveness of epithelial-like MCF-7 cells under LPS stimulation. Additionally, LPS-induced metastasis and EMT in MCF- 7-Dlb cells might depend on αvβ3 expression. Further exploration indicated that cyclin Dlb cooperated with HoxD3, a transcription factor promoting αvβ3 expression, to promote LPS- induced EMT. Knockout of HoxD3 repressed LPS-induced EMT and αvβ3 over-expression in MCF-7 cells with high expression of cyclin Dlb. Specifically, all these effects were in a cyclin Dla independent manner. Taken all together, LPS up-regulated integrin αvβ3 expression in MCF-7 cells with high expression of cyclin D lb and induced EMT in breast cancer cells, which highlights that cyclin Dlb may act as an endogenous pathway participating in exogenous signal inducing EMT in breast cancer cells.

Mesenteric phlebosclerosis with amyloidosis in association with the long-term use of medicinal liquor: A case report

BACKGROUND Mesenteric phlebosclerosis(MP)is a rare disease of the colon.The clinical manifestations of this disease are nonspecific and it may easily be misdiagnosed.We report a case of MP with amyloidosis in the colonic vessel walls in a patient with hypertension who had been consuming Chinese medicinal liquor for 10 years.We also review the relevant literature and summarize the characteristics of MP in patients in China's Mainland.CASE SUMMARY A 64-year-old man was referred to our department from his primary hospital because of abdominal pain,diarrhea,and fever for almost 10 d.Computed tomography showed colon wall thickening,with threadlike calcifications in the mesenteric vein in the transverse colon.Colonoscopy revealed purple-blue mucosa with multiple ulcers in the ascending and transverse colon.Biopsy showed thickening and calcification of the vein walls,perivascular and mucosal collagen degeneration,and amyloidosis.The patient had been consuming Chinese medicinal liquor,mainly that made from gardenia fruit,for 10 years.Based on these results,a diagnosis of MP with amyloidosis was made.After conservative treatment,the patient’s discomfort subsided and he was followed closely.The use of Chinese herbal medicine was suspected to play a role in the pathogenesis of MP.CONCLUSION The clinical manifestations of MP are nonspecific.Recognition of its typical imaging findings,including multiple calcifications on computed tomography and purple-blue mucosal discoloration on colonoscopy,is vital.
