[Effects of constructing vestibular rehabilitation exercise platform based on BS model on vertigo symptoms, balance ability and anxiety of vertigo patients].

Objective:To explore the effect of vestibular rehabilitation exercise platform based on browser server（BS） mode on vertigo symptoms, balance ability and anxiety of vertigo patients. Methods:The clinical data of 110 patients with vertigo in our hospital were retrospectively analyzed. The patients who received routine vestibular rehabilitation exercise from March 2019 to may 2020 were set as the control group （55 cases）, and the patients who received vestibular rehabilitation exercise platform guidance based on BS mode from June 2020 to December 2021 were set as the study group （55 cases）. The scores of Fugl Meyer balance assessment scale（FMA）, hospital anxiety and Depression Scale（had）, vertigo disorder scale（DHI）, quality of life scale（SF-36）, vertigo visual analog scale（VAS）, Berg Balance Scale（BBS）, rehabilitation treatment effect and rehabilitation exercise compliance were compared between the two groups. Results:before rehabilitation exercise, there was no significant difference in the scores of DHI, VAS, FMA, BBS, had and SF-36 between the two groups（P>0.05）. After 3 months of exercise, the scores of DHI, had and vas in the study group were lower than those in the control group, and the scores of FMA, BBS and SF-36 in the study group were higher than those in the control group（P<0.05）. The excellent and good rate of rehabilitation efficacy and treatment compliance rate in the study group were higher than those in the control group（P<0.05）. Conclusion:The vestibular rehabilitation exercise platform based on CS mode can improve the limb movement and balance ability of patients with vertigo, reduce the vertigo symptoms and psychological anxiety, and improve the rehabilitation treatment effect and compliance of patients.

High-Quality Genome Resource of Clonostachys rosea Strain CanS41 by Oxford Nanopore Long-Read Sequencing.

Clonostachys rosea is a necrotrophic mycoparasitic fungus with excellent biological control ability against numerous fungal plant pathogens. Here, we performed genomic sequencing of C. rosea strain CanS41 using Oxford Nanopore sequencing technology. We generated a high-quality genome assembly (>99.99% accuracy), which comprised 26 contigs containing 60.68 Mb sequences with a GC content of 48.55% and a repeat content of 8.38%. The N50 contig length is 3.02 Mb. In total, 20,818 protein-coding genes were identified and functionally annotated. Genes encoding secreted proteins and carbohydrate-active enzymes as well as secondary metabolic gene clusters were also identified and analyzed. In summary, the high-quality genome assembly and gene annotation provided here will allow further exploration of biological functions and enhance biological control ability of C. rosea.

Stage-specific regulation of purine metabolism during infectious growth and sexual reproduction in Fusarium graminearum.

Ascospores generated during sexual reproduction are the primary inoculum for the wheat scab fungus Fusarium graminearum. Purine metabolism is known to play important roles in fungal pathogens but its lifecycle stage-specific regulation is unclear. By characterizing the genes involved in purine de novo and salvage biosynthesis pathways, we showed that de novo syntheses of inosine, adenosine and guanosine monophosphates (IMP, AMP and GMP) are important for vegetative growth, sexual/asexual reproduction, and infectious growth, whereas purine salvage synthesis is dispensable for these stages in F. graminearum. Addition of GMP rescued the defects of the Fgimd1 mutant in vegetative growth and conidiation but not sexual reproduction, whereas addition of AMP rescued all of these defects of the Fgade12 mutant, suggesting that the function of de novo synthesis of GMP rather than AMP is distinct in sexual stages. Moreover, Acd1, an ortholog of AMP deaminase, is dispensable for growth but essential for ascosporogenesis and pathogenesis, suggesting that AMP catabolism has stage-specific functions during sexual reproduction and infectious growth. The expression of almost all the genes involved in de novo purine synthesis is downregulated during sexual reproduction and infectious growth relative to vegetative growth. This study revealed that F. graminearum has stage-specific regulation of purine metabolism during infectious growth and sexual reproduction.
