Objective To investigate the self-healing status of children with abnormal tongue root sounds at different age stages of 4 to 12 years old who have not received articulation training,and to provide correct guidance plans for patients.Methods Through retrospective analysis,114 cases of children diagnosed with functional dysar-thria and abnormal root of tongue in Kunming children's hospital from 2019 to 2020 who refused to do rehabilitation training but could receive long-term outpatient follow-up visit,were selected.The follow-up visit was conducted one year later to reevaluate the root of tongue of the children,and the relationship between the self-healing situation of the children's root of tongue and age and wrong form was statistically analyzed.Results Among the 114 children with abnormal root sound,35 cases(30.70％)healed by themselves.The self-healing rates of each age group were as follows:4～5 years old(45.24％),5～6 years old(27.08％),6～7 years old(14.29％),7～12 years old(10.00％).The self-healing rate of all age groups was significant(x2=8.254,P=0.041).There were 287 fre-quency of errors in 114 cases,among which the self-healing rate of consonant loss was the highest(41.46％),fol-lowed by consonant substitution(40.76％),and consonant distortion was the worst(16.67％).The overall differ-ence of the three error forms was statistically significant(x2=10.003,P=0.007).According to different root sounds,the self-healing rate of/h/sound was the highest(31/60.78％),followed by/k/sound(40,32.26％),and/g/sound was the worst(35,31.25％).There was significant difference among the three root sounds(x2=15.172,P＜0.001).There was no significant difference in the self-healing rate between male and female children(x2=1.311,P=0.252).Conclusion The rate of root sound healing in children with functional articulation disor-der was related to age,wrong form and wrong root sound,but not gender.

Objective:To explore the diagnostic value of 18F-prostate specific membrane antigen (PSMA) PET/CT PRIMAY score combined with multiparameter MRI (mpMRI) PI-RADS score for clinically significant prostate cancer (CsPCa). Methods:The data of 63 patients with prostate cancer who underwent radical prostatectomy at Beijing Hospital from January 2019 to December 2023 were retrospectively analyzed. The median age was 70 (64, 75) years old with prostate-specific antigen (PSA) level of 8.46 (5.40, 14.80) ng/ml. All patients underwent 18F-PSMA PET/CT and mpMRI examination before surgery, and pathological large sections of prostate specimens were made after surgery. The prostate lesions were diagnosed and located by two radiologists and one pathologist respectively. Lesions with Gleason scores (GS)≥3+ 4 from the surgical pathology were diagnosed with CsPCa, and lesions with negative or GS=6 were diagnosed with non-CsPCa. The PSMA PET/CT images were evaluated using the PRIMARY study criteria (5-level PRlMARY score): no pattern (score of 1), diffuse transition zone or central zone(not focal) (score of 2), focal transition zone(score of 3), focal peripheral zone(score of 4), or an SUV max of at least 12 (score of 5). The degree of uptake of imaging agent in prostate lesions was semi-quantitatively evaluated using lesion-to-background ratios (LBR) of SUV max. MpMRI was evaluated according to the Prostate Imaging Reporting and Data System (PI-RADS) version 2.1. The patients were divided into CsPCa group and non-CsPCa group based on patients and lesions. Mann-Whitney U test and chi-square test were used to compare the differences between groups. Multivariate logistic regression analysis was performed to determine the independent predictive factors of CsPCa. Receiver operator characteristic (ROC) curve was used to determine the optimal diagnostic threshold for each independent predictor. Predictive models were constructed for PRIMARY score, PI-RADS score, and their combined application, and the diagnostic performance of each model for CsPCa was compared. Results:Of all 63 patients, there were 54 cases in CsPCa group (85.7%) and 9 cases in non-CsPCa group (14.3%).There was significant difference between CsPCa group and non-CsPCa group in the serum PSA level [9.64 (6.1, 15.3) ng/ml vs. 5.6 (4.6, 7.6) ng/ml]( P<0.05). There was no statistically significant difference in age [71 (64, 75) years vs. 65 (63, 69) years], and number of lesions [2 (1, 2) vs. 2 (1, 3)] (all P>0.05). Of all 109 lesions, there were 81 lesions in CsPCa group(including 49 lesions with Gleason score = 3+ 4, 16 lesions with Gleason score=4+ 3, 14 lesions with Gleason score = 8, and 2 lesions with Gleason score>8) and 28 lesions in non-CsPCa group(including 14 lesions with Gleason score = 3+ 3 and 14 with benign prostate lesions). There was significant difference between CsPCa group and non-CsPCa group in PRIMARY score [4 (3, 5) vs. 2 (1, 4)], LBR [2.69 (2.08, 4.48) vs. 1.89 (1.45, 2.48)], PI-RADS score [4 (3, 5) vs. 2 (2, 3)] (all P<0.05). There was no statistically significant difference in the lesion distribution including the number of lesions located in the transition zone [15(18.5%) vs. 8(28.6%)] and in the peripheral zone[66(81.5%) vs. 20(71.4%)]( P>0.05). Multivariate logistic regression analysis indicated that PRIMARY score ( OR=2.134, 95% CI 1.429-3.187) and PI-RADS score ( OR=2.689, 95% CI 1.618-4.469) were independent predictors of CsPCa (both P<0.01). ROC curves analysis revealed that the cut-off value for diagnosing CsPCa was both 3 for PRIMARY score and PI-RADS score. The accuracy for PRIMARY score, PI-RADS score, and their combined complication in diagnosing CsPCa was 72%, 67%, and 83%, respectively. The sensitivity was 72%, 63%, and 91%, and the specificity was 75%, 79%, and 57%, respectively. The positive predictive value was 89%, 89%, and 86%, and the negative predictive value was 48%, 42%, and 70%, respectively. The area under the curve of the PRIMARY score, PI-RADS score, and their combined complication of the ROC curve for CsPCa were 0.733 (95% CI 0.624-0.842), 0.708 (95% CI 0.599-0.817), and 0.743 (95% CI 0.623-0.862), respectively. The diagnostic efficacy of their combined complication was higher than PRIMARY score or PI-RADS score alone (both P<0.01). Conclusions:Both the 18F-PSMA PET/CT PRIMAY score and the mpMRI PI-RADS score have good diagnostic value for CsPCa. The combined application of the two imaging parameters can improve the accuracy, sensitivity, and negative predictive value, which have a higher diagnostic efficiency of CsPCa.

Tuberculosis is a worldwide chronic infectious disease that has become a serious threat to human health.Early diagnosis,drug resistance screening and control of disease transmission are key aspects of TB prevention and treatment.However,existing diagnostic techniques and drug sensitivity tests are time-consu-ming and difficult to realize the purpose of early diagnosis and drug resistance screening,which greatly limits the control of disease transmission.Digital polymerase chain reaction(dPCR)is the third generation of poly-merase chain reaction(PCR),which is a quantitative nucleic acid assay with high sensitivity and no calibration curve.This article provides an overview of the principles of dPCR and its application in tuberculosis diagnosis,drug resistance screening and transmission monitoring,compares dPCR with other tuberculosis detection methods,and looks at the challenges and future prospects of dPCR in clinical tuberculosis laboratory applica-tions.

Nucleotide-binding oligomerization domain 1 (NOD1), a cytosolic pattern recognition receptor protein, plays a crucial role in innate immune responses. However, the functional expression of NOD1 in mesenchymal stem cells (MSCs) derived from endometriosis remains unclear. The aim of this study was to explore the functions of NOD1 in ectopic endometrial lesions. Tissues and MSCs were isolated from both normal endometrium and endometriosis.Immunohistochemistry and real time quantitative polymerase chain reaction (RT-qPCR) were used to determine the expression of NOD1 in the tissues/MSCs. Quantification of various cytokines was performed using RT-qPCR and enzyme-linked immunosorbent assay. To confirm the proliferation, invasion/migration, and apoptotic viabilities of the samples, Cell Counting Kit-8, clonogenic formation, transwell assays, and apoptotic experiments were conducted.Higher levels of NOD1 expression were detected in the ectopic-MSCs obtained from endometriosis compared to those from the endometrium. The expression of interleukin-8 was higher in the ectopic-MSCs than in the eutopic-MSCs.Pretreatment with NOD1 agonist significantly enhanced the proliferation and invasion/migration of eutopic-MSCs.Additionally, the NOD1 inhibitor ML-130 significantly reduced the proliferation, clone formation, invasion, and migration abilities of the ectopic-MSCs, having no effect on their apoptosis capacity. Our findings suggest that the expression of NOD1 in ectopic-MSCs may contribute to the progression of ectopic endometrial lesions.

Myocardial dysfunction is the most serious complication of sepsis. Sepsis-induced myocardial dysfunction (SMD) is often associated with gastrointestinal dysfunction, but its pathophysiological significance remains unclear. The present study found that patients with SMD had higher plasma gastrin concentrations than those without SMD. In mice, knockdown of the gastrin receptor, cholecystokinin B receptor (Cckbr), aggravated lipopolysaccharide (LPS)-induced cardiac dysfunction and increased inflammation in the heart, whereas the intravenous administration of gastrin ameliorated SMD and cardiac injury. Macrophage infiltration plays a significant role in SMD because depletion of macrophages by the intravenous injection of clodronate liposomes, 48 h prior to LPS administration, alleviated LPS-induced cardiac injury in Cckbr-deficient mice. The intravenous injection of bone marrow macrophages (BMMs) overexpressing Cckbr reduced LPS-induced myocardial dysfunction. Furthermore, gastrin treatment inhibited toll-like receptor 4 (TLR4) expression through the peroxisome proliferator-activated receptor α (PPAR-α) signaling pathway in BMMs. Thus, our findings provide insights into the mechanism of the protective role of gastrin/CCKBR in SMD, which could be used to develop new treatment modalities for SMD.

Objective:To investigate the risk factors related to the contrast-induced nephropathy(CIN)occurring after carotid artery stenting(CAS)in patients with carotid artery stenosis.Methods:The clinical data of 137 patients with carotid artery stenosis, who were treated with CAS at Xuanwu Hospital, Capital Medical University during the period from January to Decmber 2021 were retrospectively analyzed. Record demographic characteristics (age, gender, height, weight), history of underlying diseases (hypertension, diabetes, kidney disease, etc.), history of medications, etc. Observe the clinical parameters such as creatinine, blood urea nitrogen, albumin, hemoglobin, hematocrit, degree of stenosis and estimated glomerular filtration rate (eGFR). Measurement data conforming to the normal distribution were expressed as the mean±standard deviation( ± s), and the t-test was used for comparison between groups; the measurement data that does not conform to the normal distribution were expressed as the median (interquartile range) [ M( Q1, Q3)], and the Rank-sum test was used for comparison between groups; the Chi-square test or Fisher exact test was used for comparison of count data between groups. Relevant variables were subjected to univariate analysis, and statistically significant indicators were selected according to the results of univariate analysis to be included in the multivariate Logistic regression analysis. Results:After CAS, a total of 29 patients (21.2%) among the 137 patients developed CIN. Univariate analysis indicated that bilateral carotid artery stenosis, uncontrolled hypertension before surgery, history of angiotensin converting enzyme inhibitor drugs, diabetes mellitus, history of insulin drugs, eGFR<45 mL/(min·1.73 m 2), body weight were the influencing factors associated with the occurrence of CIN after CAS in patients with carotid artery stenting; multivariate regression analysis revealed that the presence of bilateral carotid artery stenosis( OR=4.724, 95% CI: 1.455-15.338, P=0.010), diabetes mellitus( OR=3.451, 95% CI: 1.345-8.858, P=0.010) and eGFR <45 mL/(min·1.73 m 2)( OR=4.582, 95% CI: 1.001-20.971, P=0.050) were the independent risk factors related to the CIN after CAS. Conclusion:Patients with the presence of bilateral carotid artery stenosis, diabetes mellitus or eGFR <45 mL/(min·1.73 m 2) are more likely to develop CIN after CAS.

Objective:To investigate differences in bacterial and fungal microbiome between infected nails and healthy nails among patients with onychomycosis.Methods:Nail scraping samples were collected from infected nails and healthy nails of 31 patients with onychomycosis, who visited Dalian Dermatosis Hospital from August 2020 to July 2021. The total DNA of nail microbiota was extracted, and the V3-V4 regions of the bacterial 16S rDNA gene and the fungal internal transcribed spacer (ITS) region were amplified and sequenced using Illumina technology. The USEARCH and mothur softwares were used for data cluster analysis to obtain the operational taxonomic units (OTUs) , Wilcoxon rank sum test was used to analyze α diversity, analysis of similarities (ANOSIM) was performed to analyze β diversity, linear discriminant analysis of effect size (LEfSe) was performed to evaluate the species difference.Results:Among the 31 patients with onychomycosis, 16 were males and 15 were females. According to the age, they were divided into young group (18 - 35 years old, 10 cases) , middle-aged group (36 - 60 years old, 11 cases) , and elderly group (over 60 years old, 10 cases) . As the α-diversity analysis revealed, the infected nail group showed significantly decreased Shannon index ( W = 290, P = 0.007) , but significantly increased Simpson index ( W = 663, P = 0.010) compared with the healthy nail group, suggesting that the diversity and evenness of bacterial communities were lower in the infected nail group than in the healthy nail group; however, there was no significant difference in the diversity of fungal communities between the infected nail group and healthy nail group. The β-diversity analysis based on the unweighted-UniFrac distance matrix showed no significant difference in the fungal or bacterial community composition between the infected nail group and healthy nail group (bacterial communities: R = 0.0052, P = 0.331; fungal communities: R = 0.0036, P = 0.337) ; the β-diversity analysis based on the weighted-UniFrac distance matrix showed significant differences in the abundance of bacterial and fungal communities between the two groups (both P = 0.001) . In terms of the species composition, the bacterial flora with significantly decreased abundance in the infected nail group compared with the healthy nail group included Bacteroidetes, Proteobacteria, Betaproteobacteria, Burkholderiales, Ralstonia, Sphingomonas and Streptococcus, while the abundance of Bacilli, Bacillales and Staphylococcus was significantly higher in the infected nail group than in the healthy nail group. Compared with the healthy nail group, the fungal flora with significantly increased abundance in the infected nail group included Eurotiomycetes, Onygenales, Leotiomycetes-ord-incertae-sedis, Arthrodermataceae, Periconia, Erysiphe, Tilletiopsis, Trichophyton, Erysiphe cruciferarum, Trichophyton rubrum, Malassezia sympodialis, while the abundance of Saccharomycetes, Saccharomycetales, Saccharomycetaceae, Dothioraceae, Candida and Alternaria was significantly lower in the infected nail group than in the healthy nail group. Conclusion:The diversity and abundance of bacterial communities significantly differed between infected nails and healthy nails among patients with onychomycosis, while only the abundance of fungal communities differed between the two groups, and perhaps there was correlations between some bacterial and fungal communities.

Objective:To investigate the incidences of metachronous advanced adenoma (MAA) in patients with simultaneous multiple primary colorectal cancer (CRC) and patients with sporadic CRC.Methods:From January 1, 2008 to September 30, 2022, at Beijing Shijitan Hospital, Capital Medical University, CRC patients who underwent surgery and 3 years follow-up with endoscopy were enrolled. The patients completed colonoscopy at least 2 times during follow-up in 6 to 36 months after surgery, and the interval between the 2 times colonoscopies was over 6 months. Clinical data including age, gender, and tumor location, stage, pathological features, combined underlying diseases, preoperative carcinoembryonic antigen, hemoglobin and other laboratory results, baseline colonoscopy results, and detection of MAA were collected. According to age (±2 years old), gender, location of primary lesion and stage of tumor, patients with simultaneous CRC or sporadic CRC were matched at 1∶1 ratio by propensity score matching. The cumulative risks of MAA in patients with simultaneous multiple primary CRC and patients with sporadic CRC were calculated. Cox proportional hazard regression was used to analyze the influencing factors in the occurrence of MAA.Results:A total of 814 CRC patients were enrolled and matched. After paired matching, there were 36 cases of simultaneous multiple primary CRC (78 lesions) and 78 cases of sporadic CRC (78 lesions). The cumulative incidences of MAA at 1, 2 and 3 years of simultaneous CRC group were 11.1%(4/36), 22.2%(8/36) and 33.3%(12/36), respectively. The cumulative incidences of MAA at 1-, 2- and 3-year of sporadic CRC group were 3.8%(3/78), 12.8%(10/78) and 20.5%(16/78), respectively.Simultaneous CRC was correlated with an increase in the 3-year cumulative incidence of MAA ( HR=4.163, 95% confidence interval(95% CI) 1.032 to 4.721, P=0.047). Especially in left-sided CRC, the risk of MAA in simultaneous CRC increased ( HR=7.186, 95% CI 1.602 to 20.787, P=0.010). The results of multivariate cox-regression analysis indicated that detection of simultaneous advanced adenoma at baseline endoscopy was an independent risk factor of MAA ( HR=3.175, 95% CI 1.411 to 7.142, P=0.005). Conclusion:Colouoscopy follow-up should be strengthened in patients with simultaneous multiple primary CRC and simultaneous advanced adenomas.
