ABSTRACT

Objective:To investigate the value of low-energy virtual monoenergetic image (VMI) at 45 keV in visualizing the primary tumor and T staging of hypopharyngeal squamous cell carcinoma.Methods:The clinical and imaging data of 58 patients with hypopharyngeal squamous cell carcinoma from April 2018 to January 2020 at Eye & ENT Hospital, Fudan University were analyzed retrospectively. All the patients underwent a venous phase contrast-enhanced dual-source dual-energy CT scan before treatment. The VMI at 45 keV and standard linearly blended image (30% 80 kV+70% 140 kV) were acquired from dual-energy post-processing software. One senior radiologist and one junior radiologist independently assessed the visibility of the tumor on the 45 keV VMI and standard linearly blended image using a 5-point Likert rating scale. Furthermore, the senior radiologist assessed the visibility of the tumor at each subsite (piriform fossa, posterior pharyngeal wall, postcricoid region) and determined the invasion depth of the tumor (extension to esophagus, invasion to strip muscles and prevertebral muscles) and performed the T staging of the primary tumor using the two sets of images blindly. The accuracy of T staging was calculated, using pathological T staging (surgical cases) or clinical T staging (non-surgical cases) as the gold standard. The image scores of the two sets of images were compared using Wilcoxon rank sum test. McNemar-Bowker test was used to compare the accuracy of T staging using the two sets of images.Results:The overall image scores of the 45 keV VMI and standard linearly blended image from the senior radiologist were 3.5 (3, 4) and 3 (2, 3) respectively ( Z=-7.03, P<0.001), and the scores from the junior radiologist were 3 (3, 4) and 2 (2, 3) ( Z=-6.93, P<0.001). The scores of the 45 keV VMI were significantly higher than those of the standard linearly blended image in visualizing tumors in the piriform fossa, posterior pharyngeal wall, and postcricoid region, as well as in detecting invasion to the strip muscles ( P<0.05). There was no significant difference in the scores of the two sets of images in determining whether the tumor extended to esophagus or invaded prevertebral muscles ( P>0.05). Referring to pathological and clinical T stage, the accuracy of T staging determined by the 45 keV VMI and standard linearly blended image was 87.9% (51/58) and 81.0% (47/58) respectively, and the difference was not significant (χ 2=3.33, P=0.189). Conclusions:The 45 keV VMI is superior to the standard linearly blended image in visualizing tumors and detecting invasion to the strip muscles of hypopharynx squamous cell carcinoma. However, the accuracy of determining T staging using 45 keV VMI is slightly improved than that of standard linearly blended image, and the difference is not statistically significant. In determining whether the tumor extends to esophagus or invades prevertebral muscles, 45 keV VMI shows no significant advantage over standard linearly blended image.

ABSTRACT

Yersinia pestis phage is a virus that is parasitic within Yersinia pestis and can specifically lyses Yersinia pestis. The adsorption sites of phage infesting host bacteria are called receptor binding protein (RBP), including extracellular membrane protein, lipopolysaccharide, teichoteic acid, pili, flagella, capsular polysaccharide, etc., of which extracellular membrane protein and lipopolysaccharide are the receptors of Yersinia pestis phage. RBP plays a decisive role in the process of Yersinia pestis phage infecting Yersinia pestis. Therefore, the classification, isolation and application of Yersinia pestis phage are summarized; the research progress in identification and structure of Yersinia pestis phage receptor is analyzed, which is helpful in understanding the cleavage mechanism of Yersinia pestis phage and the interaction mode with Yersinia pestis from the molecular level, and provide more powerful support for in-depth study on Yersinia pestis phage receptor.

ABSTRACT

Objective:To study the basic situation of Yunnan Province Suncus murinus carrying plague phage and to explore its epidemiological significance. Methods:From 2015 to 2018, a survey of plague host animals was carried out in 10 investigation sites in the historical plague foci, new plague foci (after 1982) and stubborn plague foci of domestric mouse in Yunnan Province. The plague phage was isolated and cultured from the intestinal specimens of Suncus murinus. The growth of plaque was observed by double-layer plate method, and the morphology and structure of plague phage were observed under electron microscope. At the same time, intestinal samples were taken to detect the structural gene caf1 of F1 antigen of Yersinia pestis. Results:In this study, a total of 157 Suncus murinus were captured and 16 strains of plague phage were isolated, with a total isolation rate of 10.19%. There was no difference in plague phage isolation rate between historical plague foci (10.00%, 1/10) and stubborn plague foci (16.22%, 12/74), new plague foci (4.11%, 3/73, χ 2 = 0.00, P = 0.965; Fisher test, P = 1.000). However, there was a difference in plague phage isolation rate between stubborn plague foci and new plague foci (χ 2 = 5.88, P = 0.015). There was no significant difference in the isolation rate of plague phage among different sex, growth period and habitat ( P > 0.05). The plaque morphology of the isolated plague phage was diverse, of which four strains were myotavirus phages; and all samples were negative for F1 antigen structural gene caf1. Conclusions:Suncus murinus is widely distributed in the domestic mouse plague foci in Yunnan Province, and the animals carry a certain number of plague phage. Regular surveillance of Suncus murinus and their plague phage has a certain guiding significance for the surveillance and early warning of plague in Yunnan Province.

ABSTRACT

Objective:To construct medical students' employment quality evaluation index system based on analytic hierarchy process (AHP), for providing basis to scientific and objective evaluation of medical students' employment quality.Methods:Two rounds of consultation with 21 experts were conducted to construct medical students' employment quality index and evaluation standard by Delphi method, and the weight of each index and evaluation standard determined by AHP. Excel 2007 and SPSS 21.0 were used to analyze the results of expert consultation. The enumeration data were expressed as frequency and percentage. The mean and coefficient of variation were used to describe the importance scores of experts on indicators at all levels. The positive coefficient, authority coefficient and coordination degree of experts were calculated, and the Kendall coordination coefficient ( W) test was carried out. Yaahp 6.0 is used to analyze the pairwise comparison matrix in the analytic hierarchy process to calculate the weight of the indicator. Results:The authority of expert consultation was ranged from 0.77 to 0.94, and the positive coefficient of experts was 100.00%. The evaluation system of medical students' employment quality was determined, which involved 3 first-class indexes, 9 second-class indexes and 35 third-class indexes, and the weight coefficients of each index were calculated by AHP.Conclusion:The evaluation index system of medical students' employment quality is reasonable, which can be used to provide reference standard for medical students' employment quality evaluation, and has certain application value.

ABSTRACT

To study the material basis of cold and hot properties of traditional Chinese medicines (TCMs) in Lamiaceae and to establish a cold and hot properties identification model, a database of material components of TCMs in Lamiaceae was established. A three-level classification system of material components was used to obtain the material basis of cold and hot properties of the Lamiaceae family by using data mining methods such as frequency analysis, association rule analysis, logistic regression, and feature selection. Several identification models were established to recognize the cold and hot properties. The chi-square test results showed that the material composition ratios of cold and hot properties were significantly different at the first-level, second-level, and third-level classification (P < 0.05), and the differences varied as the levels of substance classification changed. The average coefficients of variation were 42.30%, 79.07%, and 91.51% at the first-level, second-level, and third-level classification levels, respectively. In other words, in terms of the percentage differences in material composition ratio, the first-level was smaller than the second-level, and the second-level was smaller than the third-level. The results of the association rule analysis showed that under the third-level classification, there were many effective association rules, and 27 core groups and 34 specific groups of chemical components were obtained based on these rules. 15 decisive groups were obtained from the feature selection results. Multinomial logistic regression analysis was used to successfully establish a cold and hot properties identification model with an overall accuracy of 89%. The material basis of cold and hot properties of TCMs in Lamiaceae is different and intersect with each other. Twenty-seven groups of chemical components, such as bicyclic diterpenes, are the core groups of cold and hot properties, of which 15 groups are the decisive groups. The cold and hot properties are often characterized by the interaction of multiple classes of substances, and a single class of substances often cannot be used to characterize the properties. The organic combination of multiple classes of substances is the material basis of cold and hot properties.

ABSTRACT

Objective: To review the clinical characteristics, to illustrate diagnosis and management experience of orbital and cranial complications of pediatric acute rhinosinusitis. Methods: The clinical data of 24 children with orbital and cranial complications of acute rhinosinusitis who received endoscopic sinus surgery combined with drug treatment in Beijing Children's Hospital from January 2017 to December 2021 were retrospectively reviewed. There were 19 boys and 5 girls. The age varied from 13 to 159 months, with a median 47.5 months. The following diagnoses were obtained: 12 isolated subperiosteal orbital abscess, 2 associated with preseptal abscess, 2 associated with intraorbital abscess, 7 associated with optic neuritis, and 1 associated with septic cavernous sinus thrombosis. Clinical characteristics, organism isolated and outcomes were analyzed through descriptive methods. Results: All 24 patients presented with fever; 9 presented with nasal congestion and purulent discharge. The clinical manifestations of orbital infection included orbital edema, pain, proptosis and displacement of globe in all patients, while visual impairment was recognized in 7 children. Purulent drainage was cultured in 17 patients, among which 12 were positive. All patients underwent nasal endoscopic surgical interventions uneventfully, excluding one patient who required a second surgical procedure. Follow-up period ranged from 5 to 64 months. All patients resolved fully, with the exception of 2 children who got permanent blindness with visual loss preoperative. There was no recurrence or death. Conclusions: Orbital and cranial complications of pediatric acute rhinosinusitis could be severe with an occult onset. For patients with vison impairment, any signs of intracranial complications and a lack of response to conservative management, an urgent endoscopic intervention is needed.

ABSTRACT

ObjectiveTo investigate the principle and scientific connotation of Euodiae Fructus(EF) processed with Glycyrrhizae Radix et Rhizoma(Gly) by comparing the effects of unprocessed products of EF(UEF) and processed products of EF with the different proportions of Gly(GEFs) at toxic doses on oxidative stress and autophagy in the liver of mice. MethodSeventy mice were randomly divided into 7 groups, namely the control group, the UEF group, the group of the processed products of EF without Gly(PEF) and 4 groups of GEFs(the mass ratios of EF to Gly were 100∶3, 100∶6, 100∶12 and 100∶24, respectively, hereinafter referred to as the processed products of EF with the mass ratios of 100∶3, 100∶6, 100∶12 and 100∶24 of Gly). The mice were given purified water, the decoction of UEF, PEF and GEFs by gavage at a dose of 30 g·kg-1. PEF and GEFs were prepared according to the method under EF in the 2020 edition of Chinese Pharmacopoeia. Levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined by ultraviolet-visible spectrophotometry, hematoxylin-eosin(HE) staining was used to evaluate the pathological changes of liver tissue, the level of reactive oxygen species(ROS) was detected by fluorescence method, the mRNA expression of heme oxygenase-1(HO-1), quinone oxidoreductase-1(NQO1), glutathione-S-transferase 1(GSTA1), Kelch-like epichlorohydrin-associated protein 1(Keap1) and p62 were measured by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR), western blot was used to detect the protein expression of phosphorylated mammal target of rapamycin(p-mTOR), phosphorylated ribosomal p70 S6 protein kinase(p-p70S6K), p62, microtubule-associated protein 1 light chain 3Ⅰ(LC3Ⅰ) and LC3Ⅱ. ResultCompared with the control group, after 7 d of administration, the increase in body mass of mice in the UEF group began to slow down and the difference gradually increased, and the liver body index significantly increased(P<0.01), pathomorphological observation showed that the structure of hepatic lobules was disordered, and local hepatic sinuses were narrowed or disappeared, and there were inflammatory infiltration and local bleeding, the levels of ALT and AST in serum and ROS in liver tissue were significantly increased(P<0.01), and the expressions of Keap1, HO-1, NQO1, GSTA1, p62 mRNA and p-mTOR, p-p70S6K, p62 protein in liver tissue were significantly decreased(P<0.01), and LC3Ⅱ/LC3Ⅰ was significantly increased(P<0.01). Compared with the UEF group, the body mass of mice increased, and the liver body index, the levels of ALT and AST in serum, and the level of ROS in liver tissue all decreased in the groups of PEF and GEFs. Among these groups, only the liver lobules in GEF(100∶6) group were intact, and the size of liver sinuses was close to that in the control group. The mRNA expressions of Keap1, HO-1, NQO1, GSTA1 and p62 in liver tissue showed an overall upward trend in the groups of PEF and GEFs. Among these groups, only the ones of the above mRNA in the GEF(100∶6) group had a significant increase(P<0.05, P<0.01). The protein expressions of p-mTOR, p-p70S6K, p62 and LC3Ⅱ/LC3Ⅰ had a callback in the groups of PEF and GEFs, of which the protein expressions of p-mTOR, p-p70S6K and LC3Ⅱ/LC3Ⅰ in the GEF(100∶6) group and the expression of p62 protein in the GEF(100∶24) group had the largest callback. Except for p-mTOR protein, other protein expressions were statistically significant(P<0.05, P<0.01). ConclusionThe hepatotoxicity of EF is closely related to its ability to induce oxidative stress, which leads to pathological autophagy and hepatocyte damage. This ability can be reduced by the processing with different proportions of Gly, especially the ratio of 100∶6.

ABSTRACT

OBJECTIVE To provide reference for the construction of intelligent pharmacy and quality control of each link in medical institutions. METHODS The problems, difficulties, and risk points in the links of prescription extraction, allocation, drug resource utilization, prescription and child information verification in pediatric outpatient and emergency pharmacy of our hospital were sorted out to put forward the solutions. The pediatric outpatient and emergency intelligent pharmacy service system of our hospital was established, and its effectiveness was analyzed. RESULTS & CONCLUSIONS In response to the risk points of drug accumulation, dispensing errors, being prone to complaints or disputes, safety hazards in dispensing, and pharmacist’s incorrect operation in various stages such as payment, taking medicine and dispensing, pediatric outpatient and emergency intelligent pharmacy service system was established in our hospital by adding intelligent queuing links, enabling “QR codes”, introducing devices such as rapid dispensing machines, intelligent drug racks, and intelligent dismantling machines. After using the system, the average outpatient dispensing speed increased from 37.55 s/piece to 16.97 s/piece (direct delivery prescriptions) and 27.10 s/piece (non-direct delivery prescriptions), and the average emergency dispensing speed increased from 26.98 s/piece to 19.61 s/piece (P< 0.01). The walking distance for pharmacists to dispense prescriptions had decreased from 4-16 m/piece to 2-5 m/piece, and the inventory rate had shortened from 2.0-2.2 h/time to 1.5-1.7 h/time. The rate of dispensing error decreased from 0.003% to 0 (P< 0.01). At the same time, the improvement of pharmaceutical service quality has been demonstrated in terms of shortening the waiting time of family members of child, precise drug supplement and helping family members understand medication information. The application of the system can further promote pediatric outpatient and emergency pharmacy services in our hospital.

ABSTRACT

Since there is a lack of obvious clinical symptoms in the early stage of hepatocellular carcinoma (HCC), most patients have progressed to the advanced stage at the time of confirmed diagnosis. There are limited treatment options for HCC patients who miss the opportunity for surgery, so it is of great importance to find new therapeutic targets. Tumor-associated macrophages (TAMs) are a group of macrophages existing in the tumor immune microenvironment and affect the malignant behaviors of HCC cells and the state of immune escape within the tumor. This article introduces the origin and classification of TAM, summarizes the role and mechanism of TAMs in vascular proliferation, invasion and metastasis, formation and maintenance of stemness, and anti-tumor immunity in HCC, and briefly describes the current research advances in therapeutic targets for TAM, and it is pointed out that targeting TAM may be a promising direction for clinical treatment.

ABSTRACT

ObjectiveTo construct the mental health benefits of physical activity of Tai Chi and framework for college students based on International Classification of Functioning, Disability, and Health (ICF), and to systematically review the effect of physical activity of Tai Chi on anxiety, depression and sleep quality of college students. MethodsRelevant literatures about the health outcomes on anxiety, depression and sleep quality of college students participating in physical activity of Tai Chi were retrieved from databases of Web of Science, PubMed, Medline, Scopus, CNKI, Wanfang data, from the establishment to November 10th, 2022, and screened and reviewed. ResultsTen randomized controlled trials were included finally, from China and U.S., involving 960 participants (aged 16.4 to 40 years). The main sources were from journals about physical activity and health, with publication dates from 2016 to 2021. The quality of the included literatures was evaluated using the Physical Therapy Evidence Database (PEDro) scale with a mean score of 6.3. The main mental health problems of college students mainly focused on depression, anxiety, high stress, and poor sleep quality. The physical activity of Tai Chi included 24 simplified Tai Chi and Chen style Tai Chi. The frequency of physical activity of Tai Chi was mainly 1 to 6 times a week, 45 to 90 minutes (60 minutes mostly) a time, for 4 to 18 weeks. The health benefits of Tai Chi on anxiety, depression, and sleep quality for college students in the ICF were mainly in the affective function (b152), psychomotor function (b147), energy and drive function (b130), and sleep function (b134). The beneficial outcomes of physical activity of Tai Chi involved reducing anxiety, alleviating depressive symptoms and reducing stress. Compared with physical activity of Tai Chi, physical activity of Tai Chi with the addition of a twenty-four-pattern Taijiquan theory course was more effective in improving depression levels in patients with mild and moderate depression. Tai Chi also can help to improve sleep quality, shorten the time to sleep, and reduce sleep disturbances and daytime dysfunction. ConclusionA PICO framework of Tai Chi for the health benefits of college students has been constructed using ICF. Tai Chi engaged in by college students are mainly 24 simplified Tai Chi. The frequency of physical activity of Tai Chi is 45 to 90 minutes (60 minutes mostly) a time, 1 to 6 times a week, for 4 to 18 weeks. The physical activities of Tai Chi can benefit in reducing anxiety and depression of college students and improving the quality of sleep.

ABSTRACT

Tuberculosis (TB) is an infectious disease that poses a serious threat to human health. About a quarter of the world's population were infected with Mycobacterium tuberculosis in 2020, and the majority of them were latently infected. Approximately 5%-10% of the population with latent tuberculosis infection may progress to active TB disease. Identifying latent TB infection from active TB by biomarkers and screening people with latent TB infection at high risk of progression for preventive treatment by biomarkers that can reliably predict the progression is one of the most effective strategies to control TB. This article reviews the progress of research on transcriptional and immunological biomarkers for identifying TB infection and predicting the progression from latent infection to active TB, with the aim of providing new ideas for tuberculosis control.

ABSTRACT

OBJECTIVES@#To study the significance of E-cadherin and the association between E-cadherin methylation status and prognosis in children with acute lymphoblastic leukemia (ALL) by examining the mRNA and protein expression of E-cadherin and its gene methylation status in bone marrow mononuclear cells of children with ALL.@*METHODS@#The samples of 5 mL bone marrow blood were collected from 42 children with ALL who were diagnosed for the first time at diagnosis (pre-treatment group) and on day 33 of induction chemotherapy (post-treatment group). RT-qPCR, Western blot, and methylation-specific PCR were used to measure the mRNA and protein expression of E-cadherin and the methylation level of the E-cadherin gene. The changes in each index after induction chemotherapy were compared.@*RESULTS@#The mRNA and protein expression levels of E-cadherin in the post-treatment group were significantly higher than those in the pre-treatment group (P<0.05), while the positive rate of E-cadherin gene methylation in the post-treatment group was significantly lower than that in the pre-treatment group (P<0.05). At the end of the test, the children with negative methylation had significantly higher overall survival rate and event-free survival rate than those with positive methylation (P<0.05).@*CONCLUSIONS@#E-cadherin expression is associated with the development of ALL in children, and its decreased expression and increased methylation level may indicate a poor prognosis.

ABSTRACT

The hemodynamic characteristics of venous reflux are associated with infertility in patients with varicocele; however, an effective method for quantifying the structural distribution of the reflux is lacking. This study aimed to predict surgical outcomes using a new software for venous reflux quantification. This was a retrospective cohort study of a consecutive series of 105 patients (age range: 22-44 years) between July 2017 and September 2019. Venous reflux of the varicocele was obtained using the Valsalva maneuver during scrotal Doppler ultrasonography before microsurgical varicocelectomy. Using this software, the colored reflux signals were segmented, and the gray scale of the color pixels representing the reflux velocity was comprehensively quantified into the mean reflux velocity of the green layer (MRVG) and the reflux velocity standard deviation of the green layer (RVSDG). Spontaneous pregnancy and changes from baseline in the semen parameters were assessed during a 12-month follow-up period. Data were analyzed using logistic regression analysis. An association of the high MRVG group with impaired progressive motility (odds ratio [OR] = 2.868, 95% confidence interval [CI]: 1.133-7.265) and impaired sperm concentration (OR = 2.943, 95% CI: 1.196-7.239) was found during multivariate analysis. High MRVG (OR = 2.680, 95% CI: 1.086-6.614) and high RVSDG (OR = 2.508, 95% CI: 1.030-6.111) were found to be independent predictors of failure to achieve pregnancy following microsurgical repair. In summary, intense venous reflux is an independent predictor of impaired progressive motility, sperm concentration, and pregnancy outcomes after microsurgical varicocelectomy.

ABSTRACT

Objective: To study the long-term morphological stability of three-dimensional (3D) printed photosensitive resin dental models under natural light and dark conditions. Methods: Eighty sets of resin dental models were made by the desktop 3D printer from one digital standard model set, and randomly divided into two groups, namely natural light group (40 sets) and dark group (40 sets). All resin models were stored in sealed bags, with 4 model sets from each group randomly collected after 1, 3, 5, 7, 14, 21, 28, 40, 60, or 90 days of storage and 3D scanned using an optical model scanner. The root-mean-square error (RMSE) was calculated to represent the mean deviation of the difference between the digital standard model and the scanned resin model. Meanwhile, three linear indexes (the width between the canines, the width between the first molars, and the arch length) of the resin dental model were measured and compared with the corresponding values of the standard model. RMSE and the linear measurements between the digital standard model and the scanned resin models were compared between the natural light group and the dark group and among models from different time points. Results: Compared with the digital standard model, the RMSE values of 96.9% (155/160) resin dental models were less than 0.1 mm within 90-day storage. Also, at the same time point, there was no significant difference in the RMSE between the natural light group and the dark group (P>0.05). 75.0% (360/480) of the absolute values of the linear differences (differences in inter-canine width, intra-molar width, and arch length between the digital standard model and the scanned resin model) were within 0.2 mm, and about 0.1% (3/480) of the linear differences were greater than 0.5 mm, and all of the linear differences were within 0.6 mm. Conclusions: 3D-printed resin dental models can be stored stably under natural light and dark conditions for a long time.

ABSTRACT

The theory of disease prevention with traditional Chinese medicine is introduced into the prevention of chronic diseases such as hypertension. In order to fully implement the advantages of acupuncture, the three-level prevention strategy is strengthened on the whole-process intervention with acupuncture for hypertension, including prevention before disease onset, starting intervention at the early phase, and prevention disease from exacerbating. Moreover, the comprehensive management scheme, multidisciplinary coordination and participation mechanism are investigated in the field of traditional Chinese medicine for preventive treatment of hypertension.

ABSTRACT

OBJECTIVE@#To investigate the value of coronary computed tomographic angiography (CCTA)-based fractional flow reserve (CT-FFR) and plaque quantitative analysis in predicting adverse outcomes in patients with non-obstructive coronary heart disease (CAD).@*METHODS@#Clinical data of patients with non-obstructive CAD who underwent CCTA at the Affiliated Hospital of Jiangnan University from March 2014 to March 2018 were retrospectively analyzed and followed up, and the occurrence of major adverse cardiovascular event (MACE) was recorded. The patients were divided into MACE and non-MACE groups according to the occurrence of MACE. The clinical data, CCTA plaque characteristics including plaque length, stenosis degree, minimum lumen area, total plaque volume, non-calcified plaque volume, calcified plaque volume, plaque burden (PB) and remodelling index (RI), and CT-FFR were compared between the two groups. Multivaritate Cox proportional risk model was used to evaluate the relationship between clinical factors, CCTA parameters and MACE. The receiver operator characteristic curve (ROC curve) was used to assess the predictive power of outcome prediction model based on different CCTA parameters.@*RESULTS@#Finally 217 patients were included, of which 43 (19.8%) had MACE and 174 (80.2%) did not. The median follow-up interval was 24 (16, 30) months. The CCTA showed that patients in the MACE group had more severe stenosis than that in the non-MACE group [(44.3±3.8)% vs. (39.5±2.5)%], larger total plaque volume and non-calcified plaque volume [total plaque volume (mm3): 275.1 (197.1, 376.9), non-calcified plaque volume (mm3): 161.5 (114.5, 307.8) vs. 117.9 (77.7, 185.5)], PB and RI were larger [PB: 50.2% (42.1%, 54.8%) vs. 45.1% (38.2%, 51.7%), RI: 1.19 (0.93, 1.29) vs. 1.03 (0.90, 1.22)], CT-FFR value was lower [0.85 (0.80, 0.88) vs. 0.92 (0.87, 0.97)], and the differences were statistically significant (all P < 0.05). Cox regression analysis showed that non-calcified plaques volume [hazard ratio (HR) = 1.005. 95% confidence interval (95%CI) was 1.025-4.866], PB ≥ 50% (HR = 3.146, 95%CI was 1.443-6.906), RI ≥ 1.10 (HR = 2.223, 95%CI was 1.002-1.009) and CT-FFR ≤ 0.87 (HR = 2.615, 95%CI was 1.016-6.732) were independent predictors of MACE (all P < 0.05). The model based on CCTA stenosis degree+CT-FFR+quantitative plaque characteristics (including non-calcified plaque volume, RI, PB) [area under the ROC curve (AUC) = 0.91, 95%CI was 0.87-0.95] had significantly better predictive efficacy for adverse outcomes than the model based on CCTA stenosis degree (AUC = 0.63, 95%CI was 0.54-0.71) and the model based on CCTA stenosis degree+CT-FFR (AUC = 0.71, 95%CI was 0.63-0.79; both P < 0.01).@*CONCLUSIONS@#CT-FFR and plaque quantitative analysis based on CCTA are helpful in predicting adverse outcomes in patients with non-obstructive CAD. Non-calcified plaque volume, RI, PB and CT-FFR are important predictors of MACE. Compared with the prediction model based on stenosis degree and CT-FFR, the combined plaque quantitative index can significantly improve the prediction efficiency of adverse outcomes in patients with non-obstructive CAD.
