Rapid and accurate detection methods for food-borne pathogens are essential to ensure food safety and human health.One promising innovation in this area is the clustered regularly interspaced short palindromic repeats/CRISPR-associated systems(CRISPR/Cas)biosensor,which utilizes Cas protein and CRISPR RNA(crRNA)ribonucleo protein to specifically recognize target genes,and converts target signals into detectable physical and chemical signals.The CRISPR/Cas biosensor shows many advantages,such as high specificity,programmability,and ease of use,making it promising to pathogen detection.This paper introduced the principles and characteristics of CRISPR/Cas systems,along with the strategies for signal recognition,amplification,and output based on different CRISPR/Cas biosensors,and their respective applications in food-borne pathogen detection.Furthermore,the construction principles and challenges of multiple biosensors based on CRISPR/Cas were explored,as well as their potential for simultaneous detection of multiple pathogens.Finally,the challenges and future development trends of CRISPR/Cas-based biosensors in rapid pathogen detection were discussed,aiming to provide valuable reference and inspiration for biosensor designers and food safety practitioners.

Objective: The effect on fat infiltration (FI) of paraspinal muscles in degenerative lumbar spinal diseases has been demonstrated except for spinopelvic parameters. The present study is to identify the effect of spinopelvic parameters on FI of paraspinal muscle (PSM) and psoas major muscle (PMM) in patients with degenerative lumbar spondylolisthesis. Methods: A single-center, retrospective cross-sectional study of 160 patients with degenerative lumbar spondylolisthesis (DLS) and lumbar stenosis (LSS) who had lateral full-spine x-ray and lumbar spine magnetic resonance imaging was conducted. PSM and PMM FIs were defined as the ratio of fat to its muscle cross-sectional area. The FIs were compared among patients with different pelvic tilt (PT) and pelvic incidence (PI), respectively. Results: The PSM FI correlated significantly with pelvic parameters in DLS patients, but not in LSS patients. The PSM FI in pelvic retroversion (PT > 25°) was 0.54 ± 0.13, which was significantly higher in DLS patients than in normal pelvis (0.41 ± 0.14) and pelvic anteversion (PT < 5°) (0.34 ± 0.12). The PSM FI of DLS patients with large PI ( > 60°) was 0.50 ± 0.13, which was higher than those with small ( < 45°) and normal PI (0.37 ± 0.11 and 0.36 ± 0.13). However, the PSM FI of LSS patients didn’t change significantly with PT or PI. Moreover, the PMM FI was about 0.10–0.15, which was significantly lower than the PSM FI, and changed with PT and PI in a similar way of PSM FI with much less in magnitude. Conclusion FI of the PSMs increased with greater pelvic retroversion or larger pelvic incidence in DLS patients, but not in LSS patients.

Objective To investigate the expression levels and clinical significance of microRNA-383(miR-383),microRNA-4458(miR-4458),and microRNA-93(miR-93)in colorectal cancer tissue.Methods From October 2018 to October 2020,124 colorectal cancer patients who underwent surgical treatment in our hospital were regarded as the colorectal cancer group,and their adjacent normal tissues were as the adjacent control group.Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)method was applied to detect the expression levels of miR-383,miR-4458,and miR-93 in tissues;the relationship between the expression of miR-383,miR-4458,and miR-93 in colorectal cancer tissue and patient prognosis was analyzed using Kaplan-Meier curve;Cox regression was applied to analyze the prognostic factors of colorectal cancer patients.Results Compared with the adjacent control group,the expression levels of miR-383,miR-4458,and miR-93 in the colorectal cancer group were obviously lower(P＜0.05).The expression of miR-383,miR-4458,and miR-93 in colorectal cancer tissue was related to clinical and pathological features such as tumor diameter,TNM staging,lymph node metastasis,and depth of invasion(P＜0.05).The three-year survival rate of patients with high expression of miR-383 in colorectal cancer tissue(55/63,87.30％)was higher than that of patients with low expression of miR-383(41/61,67.21％)(x2=7.650,P＜0.05);the three-year survival rate of patients with high expression of miR-4458 in colorectal cancer tissue(53/60,88.33％)was higher than that of patients with low expression of miR-4458(43/64,67.18％)(x2=8.566,P＜0.05);the three-year survival rate of patients with high expression of miR-93 in colorectal cancer tissue(51/59,86.44％)was higher than that of patients with low expression of miR-93(45/65,69.23％)(x2=5.612,P＜0.05).According to multivariate Cox regression analysis,miR-383,miR-4458,and miR-93 are protective factors for the prognosis of colorectal cancer patients(P＜0.05),while tumor diameter,TNM staging,lymph node metastasis,and depth of infiltration were risk factors for the prognosis of colorectal cancer patients(P＜0.05).The area under the curve(AUC)predicted by Cox regression model is 0.917,95％CI is 0.854～0.959(Z=12.338,P＜0.05),the sensitivity is 94.29％,and the specificity is 87.64％.Conclusion The expression levels of miR-383,miR-4458,and miR-93 in colorectal cancer tissue are obviously reduced,and their expression levels are related to the clinical pathological characteristics and prognosis of colorectal cancer patients.
