OBJECTIVETo construct an eukaryotic expression plasmid for AY358935 gene and explore its function.
METHODScDNA of the AY358935 gene was amplified by reverse transcription-PCR and cloned into pGEM-Teasy. The pGEM-T-AY was validated by sequencing and served as a template for the construction of eukaryotic expression plasmid. The pcDNA3.1-AY recombinant was validated by double enzyme digestion and used for transient transfection of M14 cells. Expression of the AY358935 protein and proliferation of the M14 cells were determined respectively by Western blotting and 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) colorimetry.
RESULTSThe amplicons of RT-PCR were confirmed to have similar size with the cDNA fragment of the AY358935 gene as well as cloned region of pcDNA3.1-AY. The cloned region of pGEM-T-AY was sequenced to be identical with cDNA sequence of the AY358935 gene. M14 cells were transfected by the AY358935 gene, pcDNA3.1 and liposomes, respectively. After 48 h, expression of the AY358935 protein in M14 cells transfected with the AY358935 gene was significantly higher than other two groups. They also had a significantly higher absorbance value (A=0.74) than other two groups (A=0.39 and 0.46, respectively; P<0.05).
CONCLUSIONAn eukaryotic expression plasmid of the AY358935 gene was successfully constructed. Product of the AY358935 gene may promote the proliferation of M14 cells.

Objective:To investigate the application effect of virtual simulation combined with flipped classroom in experimental teaching of the nursing care of falls in the elderly.Methods:The 497 nursing undergraduates in the class of 2019 in Chongqing Medical University were selected as subjects and were then divided into control group (two classes with 251 students) and intervention group (two classes with 246 students). The students in the control group received traditional experimental teaching, and those in the intervention group received blended experimental teaching with virtual simulation combined with flipped classroom. At the end of the course, the use of virtual simulation platform was analyzed for the students in the intervention group, and a questionnaire survey and theoretical examination were used to compare the effect of experimental teaching between the two groups. SPSS 27.0 was used for the t-test and the chi-square test. Results:The frequency of use of the virtual simulation platform was (2.65±1.38) times per person in the intervention group, with an online learning time of 54.12-147.32 minutes. The questionnaire survey showed that compared with the control group, the intervention group had significantly higher scores of the achievement of teaching objectives and teaching satisfaction ( P<0.05). Compared with the control group after teaching, the intervention group had significantly higher scores of teaching promotion in terms of stimulating learning interest, cultivating self-learning ability, developing clinical thinking ability, improving innovation, and enhancing health education ability ( P<0.05). The intervention group had a significantly higher theoretical examination score than the control group [(79.38±5.09) vs. (77.88±4.97), P<0.05]. Conclusions:In the blended experimental teaching of the nursing care of falls in the elderly, virtual simulation combined with flipped classroom can help students master related knowledge and skills and cultivate their self-learning ability, clinical thinking ability, innovation ability, and health education ability.
