ABSTRACT
The management of drainage tube is an important part of nursing work. Patient restraint and tube fixation cannot effectively prevent unplanned extubation (UEX) when the tube is accidentally pulled by violence. The nursing innovation team of Henan Provincial People's Hospital designed a medical drainage tube anti-pull device in order to change the existing technology of preventing drainage tube disconnecting by means of restraint and fixation, and to interfere with the basic cause of drainage tube disconnection, and obtained the national utility model patent (patent number: ZL 2020 2 2843025.1). The design of sleeve and clasp is that when the drainage tube is pulled by accidental violence, the friction fastener clamps the drainage tube mechanically to achieve the purpose of braking the drainage tube and prevent the drainage tube from coming out. Card sleeve ring fracture design can be applied to drainage tubes of different diameters, and the buzzer device at the instant of the snap ring into the card set warning medical staff to the occurrence of risk events, so that the nurse can come in the first place for effective treatment, which is a fuse for surgical drainage tubes and is to timely and effectively prevent UEX.
ABSTRACT
Objective:To explore the effects of miR-181a-5p on the occurrence and development of gastrointestinal stromal tumors (GIST) through targeting CTDSPL mediating TGF-β signaling pathway.Methods:Surgical treatment of GIST patients in the First People’s Hospital of Shangqiu City from Jan. 2016 to Dec. 2019 were selected as research objects, and tumor tissue and adjacent normal tissue were collected intraoperatively. The clinicopathological data of the patients were analyzed. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression of CTDSPL gene and miR-181a-5p expression. Western blot was used to detect the protein level of CTDSPL and TGF-β signaling pathway related factors. Human gastrointestinal stromal tumor cell lines (GIST-T1) were transfected with miR-181a-5p mimic, miR-181a-5p inhibitor, or CTDSPL overexpression vector. MTT was used to detect cell proliferation activity, Transwell assay was utilized to detect cell invasion, flow cytometry was used to determine cell apoptosis in each group.Results:Compared with adjacent tissues, expression of miR-181a-5p and TGF-β signaling pathway related factors was activated while CTDSPL expression was inhibited. Tumor size, invasion depth and modified NIH grading were related to the mRNA expression level of CTDSPL gene in GIST tumor tissues (All P<0.05) . Compared with Blank group, inhibition of miR-181a-5p or CTDSPL overexpression had the ability to inhibit the cell viability and invasion, induce apoptosis. The effects of miR-181a-5p mimic on GIST-T1 can be saved by CTDSPL overexpression. Conclusion:miR-181a-5p can promote the occurrence and development of GIST by down-regulating the CTDSPL gene level and activating TGF-β signaling pathway.
ABSTRACT
In this article, medical consumable materials supply catalog technology was introduced through the principle, method and application of topic studies, at the same time bar code tags to tag and identify medical consumable materials were introduced. These two techniques established the correspondence between the real supplies logistics and information flow system, provided foundation for medical supplies all process tracking and traceability management. Supply catalog and encoding identification technology provide a new solution for the effective management of medical consumable materials.
