Objective To analyze the application of flipped classroom in the practical teaching of rehabilitation assessment courses for rehabilitation therapy majors,and to explore a new teaching method for rehabilitation therapy.Methods Eighty students majoring in rehabilitation therapy from the Department of Rehabilitation Medicine of Guangzhou Xinhua University in grade 2020 were selected as the research objects.They were assigned into observation group or control group according to the random number table method,with 40 cases in each group.The observation group adopted the flip classroom teaching mode,and the rehabilitation assessment course teaching based on flipped classroom was carried out,while the control group adopted the traditional teaching mode.The students'theoretical and operational assessment results,teaching effect,and teaching model satisfaction were analyzed.Results No statistically significant differences were found in theoretical test scores between the two student groups(by gender/course).The students in the observation group had higher theoretical scores[(80.25±11.65 vs 72.50±14.28)score].The observation group showed significantly higher satisfaction scores than the control group across all three dimensions:classroom learning enthusiasm,teacher-student interaction,and overall teaching satisfaction.(P<0.05).Conclusion The application of flipped classroom in the rehabilitation therapy teaching is helpful to improve the professional theoretical level of students,and to a certain extent,it is beneficial to improve the professional level of teachers.

Objective: To investigate the molecular mechanism of NOD-like receptor(NLR) signaling pathway induced cellular focal death in mouse kidney tissues under plateau hypoxia based on transcriptomic sequencing technology. Methods: Animal models were constructed in high-altitude kidney test group(HKT group) and plain kidney control group(PKC group),and C57/BL6 mice were bred at an altitude of 4 200 m and 400 m,respectively.Kidney tissues were aseptically taken out after 30 d and used for observation of renal histopathological changes and transcriptomics sequencing,respectively,and then differentially expressed genes(DEGs) were enriched by KEGG and GO analysis.Key gene and protein expression levels were verified by reverse transcription quantitative polymerase chain reaction(RT-qPCR) and Western blot analysis. Results: Hematoxylin-eosin(HE) staining showed that the renal tubules of HKT mice were disorganized,and the tubular epithelial cells were edematous with inflammatory cell aggregation.Transcriptomics sequencing analysis revealed that a total of 3 007 DEGs were identified in the HKT group,and KEGG analysis showed that DEGs were significantly enriched in the NLR signaling pathway.The mRNA expression of the key differentially expressed genes,CASP1,CASP11,GSDMD,IFI16,NAIP5,IRF9,and the downstream inflammatory factors,IL-1β and IL-18,was upregulated,and protein expression of CASP1,CASP11,and GSDMD was up-regulated. Conclusion The plateau hypoxic environment induces cellular pyroptosis by regulating the expression of NLR signaling pathway and releases downstream inflammatory factors to cause inflammatory responses.

Objective To investigate the molecular mechanism of lipid metabolism disorder in mouse spleen tissues due to high-altitude hypoxia.Methods Ten C57BL/6 male mice were randomly divided into normoxia group(maintained at an altitude of 400 m)and high-altitude hypoxia group(maintained at 4200 m)for 30 days(n=5).Lipidomics and metabolomics analyses of the spleen tissue of the mice were conducted using liquid chromatography-mass spectrometry(LC-MS)to identify the differential metabolites,which were further analyzed by KEGG enrichment and pathway analyses,and the differential genes were screened through transcriptome sequencing.Bioinformatics analysis was conducted to identify the upstream target genes of the differential metabolites in specific metabolic pathways.RT-qPCR and Western blotting were used to detect mRNA expressions of 11β-hydroxysteroid dehydrogenase 1(HSD11B1),steroid 5α reductase 1(SRD5A1),prostaglandin-endoperoxide synthase 1(PTGS1),hematopoietic prostaglandin D synthetase(HPGDS),xanthine dehydrogenase(XDH),purine nucleoside phosphorylase(PNP),hypoxanthine guanine-phosphoribosyltransferase(HPRT)and extracellular 5'-nucleotidase(NT5E)and protein expressions of HSD11B1,SRD5A1,XDH,PNP and HPRT in the mouse spleens.Results We identified a total of 41 differential lipid metabolites in the mouse spleens,and these metabolites and the differential genes were enriched in steroid hormone biosynthesis,arachidonic acid metabolism,and purine metabolism pathways.Compared to the mice kept in normoxic conditions,the mice exposed to high-altitude hypoxia showed significantly upregulated expressions of adrenosterone,androsterone,prostaglandin D2,prostaglandin J2,xanthine,xanthosine,and uric acid in the spleen with also changes in the expression levels of HSD11B1,SRD5A1,PTGS1,HPGDS,XDH,PNP,HPRT,and NT5E.Conclusion High-altitude hypoxia can result in lipid metabolism disorder in mouse spleen tissue by affecting steroid hormone biosynthesis,arachidonic acid metabolism,and purine metabolism pathways.

Objective:To establish a multilocus sequence typing (MLST) assay for Corynebacterium ( C.) striatum, explore the population structure and evolution relationship of clinical isolates of C. striatum. Methods:Seven housekeeping genes ( gyrA, gyrB, hsp65, sodA, secA1, rpoB, 16S rRNA) were amplified with PCR by using self-designed specific primers and sequenced. Then, the sequences were assembled with software SeqMan. The gene diversity and gene recombination characteristics were evaluated by using software DnaSP 5.10.01 and Splits tree 4.14.2. The phylogenetic tree and the minimum spanning tree were constructed based on the sequence types (ST) characteristics by using software MEGA 7.0.14 and BioNumerics, respectively. In addition, the genetic evolutionary relationship among STs were analyzed by using software eBURST 3.0. Results:The expected amplification products of seven sites selected in all the test strains were obtained. Splits tree showed that the clustering of all C. striatum strains was consistent, suggesting that gene recombination is the potential driving force for the evolution of C. striatum. All of the 344 C.striatum strains were divided into 72 STs by MLST and 85.7% of the strains formed clonal complexes. CC19 was the predominant clonal complex, whereas ST16 in the clonal complex was detected in the most strains. ST had a certain geographic clustering and a certain correlation with the isolation time. Conclusions:C. striatum showed high genetic diversity in China and CC19 was the predominant clonal complex. The MLST assay established in this study can be used for the typing of C. striatum, but further improvement is needed.

ABSTRACT OBJECTIVE：To compare the effectiveness and economics of peramivir and oseltamivir in the treatment of influenza complicated with febrile seizures in children. METHODS：In retrospective study，152 children with influenza complicated with febrile seizures were collected from our hospital during Dec. 2018 to Mar. 2019.They were divided into peramivir group（81 cases） and oseltamivir group （71 cases）. Fever remission time， medication duration， hospital duration， clinical efficacy （determined by convulsion，cough，nasal obstruction，runny nose，sore throat，etc.），the incidence of rash，the number of children with combined antibiotic and TCM were compared between 2 groups. Cost-effectiveness analysis was used to evaluate cost-effectiveness ratio（CER）and incremental cost-effectiveness ratio（ICER）of medication regimen in 2 groups. The sensitivity analysis of the effect and total cost were carried out with Logistic regression and multiple linear regression respectively through CER and ICER calculated by reducing 15％ drug price. RESULTS：There was no statistical significance in fever remission time， medication duration，hospitalization duration，the incidence of rash and proportion of children with combined antibiotics between 2 groups（P＞0.05）. There was statistical significance in proportion of children with combined TCM and clinical effect，and the proportion of children with combined TCM in peramivir group was significantly lower than oseltamivir group（P＜0.001）. Clinical effect of peramivir group was significantly better than that of oseltamivir group（P＝0.021）. Total cost of peramivir group and oseltamivir group were 5 442.84 yuan/person and 5 571.71 yuan/person（P＝0.795）；CER of them were 54.47 and 56.51；ICER of peramivir group was － 89.38. The results of sensitivity analysis were consistent with those of basic analysis.CONCLUSIONS： Compared with oseltamivir，peramivir is more effective and less costly for children with influenza and febrile seizures.
