Objective To investigate the Meta-analysis of microRNA(miRNA)in distinguishing active tu-berculosis and latent tuberculosis.Methods CNKI,Wanfang Data,VIP,PubMed,Cochrane Library,Web of Science and Embase databases were searched to select the literature on miRNA in discriminating active tuber-culosis and latent tuberculosis from the establishment of the database to April 2023,and screened strictly ac-cording to the inclusion and exclusion criteria.The quality of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2,and data extraction and summary analysis were carried out with Stata16.0 software.Heterogeneity among studies was evaluated by calculating I2,and the sources of heteroge-neity were further explored by Meta-regression and subgroup analysis.Publication bias was assessed using Deeks funnel plot.Results The Meta-analysis encompassed 9 articles,comprising 13 studies.The combined sensitivity of miRNA in differentiating active tuberculosis and latent tuberculosis was found to be 0.79(95％CI:0.69-0.86,I2=86.24％),with a specificity of 0.73(95％CI:0.64-0.81,I2=81.80％).The positive likelihood ratio was 2.96(95％CI:2.22-3.95,12=63.84％),while the negative likelihood ratio was 0.29(95％CI:0.20-0.41,I2=84.04％).Furthermore,the diagnostic odds ratio was 10.33(95％CI:6.43-16.61,I2=99.90％),and the area under the receiver operating characteristic curve was 0.83(95％CI:0.79-0.86).The results of Meta-regression and subgroup analysis showed that sample size may be the source of sensitivity heterogeneity,and dysregulation of miRNA may be the source of specificity heterogeneity.Deeks funnel plot showed no publication bias among included studies.Conclusion miRNA shows good diagnostic a-bility in distinguishing active tuberculosis and latent tuberculosis,which has important significance for impro-ving the development of diagnostic strategies for tuberculosis management.

Objective To correlate the isokinetic strength of stroke survivors' trunk flexors and extensors with the kinematic parameters of their gait.Methods Thirty stroke survivors and 30 healthy counterparts formed an observation group and a control group.The strength of everyone's trunk flexors and extensors was measured isokinetically,including the flexor peak torque (FPT),extensor peak torque (EPT) and the ratio of the two (F/E).The test velocities were 30°/s,60°/s and 90°/s.And the kinematic parameters of their gait,including the step length,stride,velocity,frequency,width and cycle time were measured using a 3D gait analysis system,as well as the percentage of stance phase,swing phase,double support phase and single support phase.Results No significant differences were found between the average FPT,EPT or F/E of the two groups at any of the three test velocities.At the 30°/s test velocity the average FPT,EPT and F/E of the observation group were all positively correlated with the average step length,stride,velocity,steps/min,width and cycle time,as well as with the stance phase,swing phase,double support phase and single support phase percentages.The strongest correlation was between F/E and velocity (r=0.57),followed by frequency (r=0.54).Conclusion litating the walking ability of stroke survivors and correcting their gait should focus on strengthening the trunk muscles and optimizing their coordination.
