ThyroidNet:A Deep Learning Network for Localization and Classification of Thyroid Nodules

Aim:This study aims to establish an artificial intelligence model,ThyroidNet,to diagnose thyroid nodules using deep learning techniques accurately.Methods:A novel method,ThyroidNet,is introduced and evaluated based on deep learning for the localization and classification of thyroid nodules.First,we propose the multitask TransUnet,which combines the TransUnet encoder and decoder with multitask learning.Second,we propose the DualLoss function,tailored to the thyroid nodule localization and classification tasks.It balances the learning of the localization and classification tasks to help improve the model’s generalization ability.Third,we introduce strategies for augmenting the data.Finally,we submit a novel deep learning model,ThyroidNet,to accurately detect thyroid nodules.Results:ThyroidNet was evaluated on private datasets and was comparable to other existing methods,including U-Net and TransUnet.Experimental results show that ThyroidNet outperformed these methods in localizing and classifying thyroid nodules.It achieved improved accuracy of 3.9%and 1.5%,respectively.Conclusion:ThyroidNet significantly improves the clinical diagnosis of thyroid nodules and supports medical image analysis tasks.Future research directions include optimization of the model structure,expansion of the dataset size,reduction of computational complexity and memory requirements,and exploration of additional applications of ThyroidNet in medical image analysis.

Endoscopic papillary large balloon dilation vs endoscopic sphincterotomy for retrieval of common bile duct stones:A meta-analysis

AIM:To compare the efficacy and safety of endoscopic papillary large balloon dilation(EPLBD)with endoscopic sphincterotomy(EST)in retrieval of common bile duct stones(≥10 mm).METHODS:PubMed,Web of Knowledge,EBSCO,the Cochrane Library,and EMBASE were searched for eligible studies.Randomized controlled trials(RCTs)that compared EPLBD with EST were identified.Data extraction and quality assessment were performed by two independent reviewers using the same criteria.Any disagreement was discussed with a third reviewer until a final consensus was reached.Pooled outcomes of complete bile duct stone clearance,stone clearance in one session,requirement for mechanical lithotripsy,and overall complication rate were determined using relative risk and 95%CI.The separate post-endoscopic retrograde cholangiopancreatography complications were pooled and determined with the Peto odds ratio and95%CI because of the small number of events.Heterogeneity was evaluated with the chi-squared test with P≤0.1 and I2 with a cutoff of≥50%.A fixed effects model was used primarily.A random effects model was applied when significant heterogeneity was detected.Sensitivity analysis was applied to explore the potential bias.RESULTS:Five randomized controlled trials with 621participants were included.EPLBD compared with EST had similar outcomes with regard to complete stone removal rate(93.7%vs 92.5%,P=0.54)and complete duct clearance in one session(82.2%vs 77.7%,P=0.17).Mechanical lithotripsy was performed less in EPLBD in the retrieval of whole stones(15.5%vs25.2%,P=0.003),as well as in the stratified subgroup of stones larger than 15 mm(24.2%vs 40%,P=0.001).There was no statistically significant difference in the incidence of overall adverse events(7.9%vs 10.7%,P=0.25),post-ERCP pancreatitis(4.0%vs 5.0%,P=0.54),hemorrhage(1.7%vs 2.8%,P=0.32),perforation(0.3%vs 0.9%,P=0.35)or acute cholangitis(1.3%vs 1.3%,P=0.92).CONCLUSION:EPLBD could be advocated as an alternative to EST in the retrieval of large common bile duct stones.

Solid neuroendocrine breast carcinoma:mammographic and sonographic features in thirteen cases

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma(NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings.The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed.Imaging data were evaluated by two radiologists for a consensual diagnosis.All patients presented with one palpable mass;only 1 experienced occasional breast pain,and 5 complained of fluid discharge.In 7 patients,the masses were firm and mobile.Regional lymph node metastasis was noted in only 1 patient.For the 10 patients who underwent mammography,6 had a mass,1 had clustered small nodules with clustered punctuate microcalcifications,2 had asymmetric focal density,and 1 had solitary punctuate calcification.Most of the masses had irregular shape with indistinct or microlobulated margins.For the 9 patients who underwent ultrasonography(US),9 masses were depicted,all of which were hypoechoic,mostly with irregular shape and without acoustic phenomena.Different types of acoustic phenomena were also identified.One patient had developed distant metastases during follow-up.NEBC has a variety of presentations,but it is mostly observed on mammograms as a dense,irregular mass with indistinct or microlobulated margins.Sonographically,it typically presents as an irregular,heterogeneously hypoechoic mass with normal sound transmission.Histories of nipple discharge and calcification observed using imaging are not rare.

Correlation study of biological characteristics of non-small cell lung cancer A549 cells after transfecting plasmid by microbubble ultrasound contrast agent

Objective: To explore the role of the abnormal expression of miRNAs in the development process of non-small cell lung cancer and the feasibility of ultrasound microbubble-mediated gene therapy after transfecting antisense miRNA-224 and miRNA-122 a plasmids into nonsmall cell lung cancer A549 cells. Methods: Antisense miRNA-224 and miRNA-122 a plasmids were transfected into non-small cell lung cancer A549 cells on the optimal ultrasound microbubble mediated condition. We set up a control group. The cell proliferation activity, apoptosis, invasion ability were detected by MTT assay, Annexin V-PE, Transwell invasion experiment and colony formation assay, respectively. Results: The expression of mi RNA-224 decreased and the expression of miRNA-122 a rose after the plasmids of target genes were transfected into non-small cell lung cancer A549 cells, and there were significant differences when compared with those of the control group(P<0.05). After the plasmids of target genes were transfected into A549 cells, the growth of antisense miRNA-224 and miRNA-122 a were inhibited, and the differences were significant as compared with the control group(P < 0.05). Besides, the inhibition of miRNA-122 a group was the most significant and there was statistically significant difference as compared with miRNA-224 group(t =-4.694, P = 0.009). After the plasmids of target genes were transfected into A549 cells, the proportion of apoptotic cells increased, the invasive cells were decreased and the clone ability reduced, and also there was a significant difference as compared with those of the control group(P < 0.05). What's more, the apoptotic peak appeared in miRNA-122 a group. Its invasion ability decreased most obviously(40.25 ± 3.97/visual field), the number of clone ability was 104.93 ± 4.87 and the inhibitory effect was the most obviously. There was statistically significant difference as compared with other groups(P < 0.05). Conclusions: A549 cells transfected by ultrasound microbubble-mediated antisense miRNA-224 and mi RNA-122 a plasmids possessed good transfection efficiency. The cell growth, invasion and colony forming abilities of transfected A549 cells were suppressed, which laid a solid foundation for the gene therapy of non-small cell lung cancer.

Objective: To evaluate the diagnostic value of color Doppler ultrasound in the diagnosis of diabetic lower extremity vascular diseases. Methods: 48 patients with diabetic lower extremity vascular disease admitted in our hos-pital from September 2018 to September 2019 were included in the study and divided into the observation group, and another 48 patients with the same period of health examination in our hospital were included in the study and divided into the control group. Both groups used color Doppler ultrasound to detect the blood flow of lower extremity vessels. The incidence of blood flow, vascular diameter and stenosis, occlusion and arteriosclerosis of the lower extremity were observed. Results: The blood flow and vascular di-ameter of the lower extremity in the observation group were significantly lower than those in the control group (p < 0.05). The incidence of vascular stenosis, vascular occlusion, thrombus, intimal thickening and plaque in the observation group was 85.42%, 22.92%, 10.42% and 93.75% respectively, which was significantly higher than that in the control group was 10.42%, 0.00%, 0.00% and 14.58% (p < 0.05). The incidence of lower extremity vascular lesions in the observation group was significantly higher than that in the control group (p < 0.05). Conclusion: Color Doppler ultrasound is of high diagnostic value in the diagnosis of diabetic lower extremity vascular diseases, and can be used to determine the blood flow of the lower extremity and the inner diameter of popliteal artery, thigh artery, dorsalis pedis artery and so on. At the same time, it can also clearly show the specific situation of vascular occlusion, arteriosclerosis and thrombosis, which is of great signif-icance for the prevention and diagnosis of lower extremity vascular lesions, and can provide the basis for the treatment of lower extremity vascular lesions.

Hope During the COVID-19 Epidemic Decreased Anxiety and Depression Symptoms Mediated by Perceived Stress:Coping Style Differences Among Patients with COVID-19

Objective:This study aimed to investigate whether perceived stress mediated the relationship between hope and anxiety/depression symptoms among patients with COVID-19 during the epidemic.In addition,the potential moderating effect of coping styles was examined.Methods:From February 26 to March 10,2020,patients with COVID-19 were asked to complete a questionnaire online,which included demographic characteristics,as well as the SCL-90-Anxiety,SCL-90-Depression,Chinese Perceived Stress Scale(CPSS),Herth Hope Index(HHI),and Trait Coping Style Questionnaire(TCSQ).Hierarchical linear regression was performed to explore independent factors of anxiety/depression.A multi-group structural equation modeling with the collected data from patients in the Negative Coping style(NC)group and Positive Coping style(PC)group was used to test the hypothesized mechanism.Results:In total,382 valid questionnaires of patients were obtained,including 96 from NC patients and 286 from PC patients.In the hierarchical linear regression,hope and perceived stress were independent risk factors for both anxiety and depression in the total sample and PC group.However,hope was not independently related to anxiety/depression in the NC group.As hypothesized,the hope of patients had significant and negative indirect effects on both anxiety and depression that were mediated by perceived stress,However,the direct effect from stress on anxiety and depression was stronger for NC patients than for PC patients.Besides,hope had significant direct effects on anxiety/depression in PC patients,but not in NC patients.Conclusion:During the COVID-19 epidemic,perceived stress could mediate the relationship between hope and anxiety/depression symptoms among COVID-19 patients,with coping style moderating this cultivation process.

Objective:To study the ultrasound features of carotid atherosclerosis in patients with coronary heart disease and their correlation with disease severity. Methods:180 patients with coronary heart disease treated in our hospital between December 2010 and December 2015 were collected as observation group and divided into single-vessel disease group (n=50), double-vessel disease group (n=72) and triple-vessel disease group (n=58) according to the degree of coronary artery stenosis;50 healthy subjects receiving physical examination in our hospital during the same period were selected as control group. Carotid ultrasound was used to measure carotid atherosclerosis parameters, cardiac color Doppler ultrasound was used to detect cardiac function parameters, enzyme-linked immunosorbent assay (ELISA) was used to detect serum endothelial function indexes, and Pearson test was used to analyze the correlation between carotid ultrasound parameters and the cardiac function as well as endothelial function. Results:Carotid ultrasound parameters stiffness (β), elastic modulus (Ep), arterial compliance (AC) and pulse wave velocity (PWVβ) value of observation group were higher than those of control group, and with the increase of coronary artery lesion severity, the changes ofβ, Ep, AC and PWVβvalue increased (P<0.05);cardiac function parameters left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) value of observation group were higher than those of control group while left ventricular ejection fraction (LVEF) value was lower than that of control group, and with the increase of coronary artery lesion severity, the changes of LVEDD, LVESD and LVEF value increased (P<0.05);endothelial function indexes endothelin-1 (ET-1) and von willebrand factor (vWF) levels of observation group were higher than those of control group while nitric oxide (NO) level was lower than that of control group, and with the increase of coronary artery lesion severity, the changes of ET-1, vWF and NO levels increased (P<0.05). Carotid ultrasound parameterβ, Ep, AC and PWVβvalue in patients with coronary heart disease were directly correlated with the levels of cardiac function parameters and endothelial function indexes. Conclusions:The ultrasound parameter levels of carotid atherosclerosis in patients with coronary heart disease are directly correlated with the disease severity and can be used as the noninvasive and reliable means for early judgment of the disease.

The effect of lens parameters on the development of the primary angle-closure glaucoma

Objective: To investigate the role the lens dimensions played on the pathogenesis of primary angle-closure glaucoma.Methods: 38 eyes of 20 patients with primary angle-closure glaucoma ( PACG) and 35 eyes of 22 normal individuals withoutocular abnormalities were examined. The anatomical parameters of the lens and other structures of the anterior segment werecalculated using B ultrasound, computer image processing and ultrasound biomicroscopy ( UBM) . The parameters were com-pared between the patients and normal subjects. Correlation analysis was used to determine the relationship between the radii ofcurvature of the anterior lens surface ( RCALS) and the other parameters of the anterior segment. Results: Compared with thenormal eyes, the eyes of PACG had thicker lens, steeper curvature of anterior lens surface, decreased depth of the anteriorchamber, narrower chamber angle, and more anterior position of the ciliary bodies and lens. All these differences were signif-icant( P < 0.05 or P < 0.01) . In the PACG group, the RCALS had significantly negative correlation with the central and pe-ripheral lens thickness ( P < 0.01 and P < 0.05 respectively) , and had positive correlation with relative lens position, anteriorchamber depth( ACD) , angle-open distance at 500 um( AOD500) , trabecular iris angle( TIA) and trabecular ciliary processesdistance( TCPD, P < 0.05 or P < 0.01) . Conclusion: The occurrence of PACG is relevant to the abnormal anatomical struc-tures of the anterior segment. Among all factors, the lens parameters play an important role in the pathogenesis. Increased lensthickness, relative more anterior position of lens, especially steepened curvature of anterior lens surface are predisposing factorsof the pathologic phenomenon in PACG including pupillary blockage, shallow anterior chamber, secondary closure of chamberangle and elevation of intraocular pressure.
