Objective:To explore the clinical efficacy of biopsy forceps polypectomy with submucosal injection for diminutive colorectal polyps.Methods:The patients with diminutive colorectal polyps (long diameter≤5 mm in size) who received polypectomy in Quanzhou First Hospital Affiliated to Fujian Medical University from May 2021 to May 2022 were prospectively recruited and divided into the observation group (biopsy forceps polypectomy with submucosal injection) and the control group (traditional biopsy forceps polypectomy). The location, morphology, long diameter, the complete polypectomy rate under direct vision, the time of resection and endoscopy withdrawal, pathological results, specimen collection rate, the incidence of complications and endoscopic treatment cost were analyzed. The clinical efficacy of the two methods were compared.Results:A total of 292 patients were included in the study, with 146 in the observation group and 146 in the control group. There were 258 polyps in the observation group and 252 polyps in the control group. The complete polypectomy rate was higher in the observation group than that in the control group [100.0% (258/258) VS 90.1% (227/252), χ2=26.915, P=0.001] with clear vision. The incidence of complications in the observation group was lower than that in the control group (1/146 VS 13/146, χ2=10.804, P=0.001) , along with the lower treatment cost (173.7±15.9 yuan VS 184.0±53.8 yuan, Z=-2.777, P=0.005). The resection time in the observation group was longer than that in the control group, but the difference was not statistically significant [10 (9,11) min VS 9 (9,11) min, Z=-0.528, P=0.597]. There was no significant difference in the polyp position, long diameter, morphology, pathological classification, or the specimen collection rate between the two groups ( P>0.05). Conclusion:Biopsy forceps polypectomy with submucosal injection is safe for diminutive colorectal polyps, and it demonstrates a higher complete polypectomy rate, lower complication rates, and reduced treatment costs compared with traditional biopsy forceps polypectomy. It is a new perspective for managing diminutive colorectal polyps.

Cluster of differentiation 36 (CD36) is a membrane glycoprotein receptor capable of binding and transporting fatty acid. Nogo-B regulates the metabolism of fatty acids in the liver and affects the development of liver cancer. To date, it remains unclear whether the interaction between CD36 and Nogo-B affects the proliferation and migration of breast cancer cells. In the current study, we aimed to determine whether the interference of CD36 and Nogo-B affects the proliferation and migration of triple-negative breast cancer (TNBC) cells. The results showed that inhibition of CD36 or Nogo-B alone can inhibit the proliferation and migration of TNBC cells, and the inhibitory effect was more pronounced when CD36 and Nogo-B were inhibited simultaneously. Meanwhile, it was found that inhibition of CD36 and Nogo-B expression can inhibit the expression of Vimentin, B-cell lympoma-2 (BCL2) and proliferating cell nuclear antigen (PCNA). In vivo, knockdown of CD36 or Nogo-B in E0771 cells reduced its tumorigenic ability, which was further enhanced by knockdown of CD36 and Nogo-B simultaneously. Mechanistically, inhibition of CD36 and Nogo-B expression can decrease fatty acid binding protein 4 (FABP4) and fatty acid transport protein 4 (FATP4) expression. Moreover, overexpression of CD36 and Nogo-B-induced cell proliferation was attenuated by FABP4 siRNA, indicating that inhibition of CD36 and Nogo-B expression could inhibit the absorption and transport of fatty acids, thereby inhibiting the proliferation and migration of TNBC. Furthermore, inhibition of CD36 and Nogo-B expression activated the P53-P21-Rb signaling pathway which contributed to the CD36 and Nogo-B-inhibited proliferation and migration of TNBC. Taken together, the results suggest that inhibition of CD36 and Nogo-B can reduce the proliferation and migration of TNBC, which provides new targets for the development of drugs against TNBC.
