Serum miRNA Combined With Transvaginal Color Doppler Ultrasound Diagnosis Clinical Research on Cervical Cancer.

To explore clinical value of miRNA-18a, miRNA-130a, and miRNA-92a combined with transvaginal color Doppler ultrasound (TVCDS) in the diagnosis of cervical cancer (CC). One hundred patients with pathologically confirmed CC (CC group), 100 patients with cervical epithelial neoplasia (disease group), and 100 patients with benign uterine lesions (control group) were selected. TVCDS was performed, and the levels of serum miRNA-18a, miRNA-130a, and miRNA-92a were detected. The systolic blood velocity of the cancer group, the disease group, and the control group decreased sequentially, while the resistance index and pulsatility index increased sequentially. The serum miR-18a, miR-130a, miR-92a, and expression levels of the patients' increased sequentially. Multivariate logistic regression analysis showed that age, high-risk human papillomavirus (HR-HPV) infection, menopause, blood flow RI, serum miRNA-18a, miRNA-92a, and miRNA-130a were the influencing factors of CC. The receiver operating characteristic curve showed that the sensitivity, specificity, accuracy, and area under curve of transvaginal Doppler ultrasound in the diagnosis of CC were 86.43%, 88.01%, 84.32%, and 0.913; serum miR-18a were, respectively, 76.56, 81.30, 80.36, and 0.839; serum miR-130a were 77.88%, 76.97%, 78.32%, and 0.0.864; serum miR-92a were 71.04%, 80.39%, 80.74%, and 0.894; 90.33%, 95.14%, 91.25%, and 0.947, the area under curve of the combined detection of the 3 was greater than that of the single detection. Serum miRNA combined with TVCDS has the advantages of it being noninvasive, and having high sensitivity and high specificity in the diagnosis of CC.

Clinical Analysis of Color Doppler Ultrasound Diagnosis of Senile Cataract Based on Intelligent Processor.

In order to improve the effect of on-the-spot diagnosis of senile cataract, this paper combines the intelligent processor to explore the application of color Doppler ultrasound in the clinical analysis of senile cataract. Moreover, this paper measures and calculates the diameter, perimeter, area, volume, or velocity of blood flow reflected by color Doppler ultrasound images. In addition, this paper adopts the measurement method provided by composite measurement to design the intelligent processor. Each measurement analysis package is defined as an independent class, and the data, properties, and methods are encapsulated in a class, which is beneficial to the modular design of the program and the overall management of the system. The experimental results verify that the intelligent processor proposed in this paper has a certain effect in the clinical analysis of color Doppler ultrasound diagnosis of senile cataract.

The value of color Doppler sonography in diagnosis and hemodynamic analysis of innominate artery occlusion

The occlusion of the innominate artery caused a significant decrease in the distal end of the right subclavian artery and the right common carotid artery, internal carotid artery, and external carotid artery (ECA). Due to the different pressure and the abundant communicating arteries between the ECA and the bilateral vertebral artery (VA), different paths of blood steal in the anterior and posterior circulation occurred.

​Color Doppler Ultrasonographic Characteristics of Embryonic Development and Mortality in Dairy Cows

Background: Embryonic mortality is one of the major factors leading to reproductive failure, decreased fertility and delayed pregnancy in cattle. Method: The study was aimed for investigating the incidence of embryonic mortality(EM), differentiate embryonic development and mortality based on color Doppler ultrasonographic characteristics. Different characteristics correlated were corpus luteum(CL) vascularity, embryonic development and EM features, monitored on day 21 post-insemination. Result: The overall incidence of EM was recorded to be 25%, with 15% and 10% mortality occurred between days 21-28 and 28-35 of gestation. Color Doppler analysis stated that, the CL in pregnant cows had a higher percentage of luteal tissue with positive Doppler signals on initial examination (day 21) differing significantly (P less than 0.01) from non-pregnant and consistently increased till the end of the examination. However, cows with EM had a significantly lower CL vascularity than pregnant (P less than 0.05) but significantly higher (P less than 0.05) than non-pregnant cows on day 21. Embryos from pregnant cows (detected by 28 days) increased in size along the days of examination. However, cows diagnosed with EM showed signs (day 28), which included reduced intra-uterine allantoic fluid, absence of embryo proper with an embryonic heartbeat, hyperechoic free-floating embryonic debris in the uterus and distorted allanto-chorionic membrane. In conclusion, the present study firmly supports color Doppler ultrasonography in diagnosis of pregnant cows based on CL vascularity, visualizing the different characteristics signs of EM, and detecting non-pregnant animals undergoing EM as early as day 21.

Backpropagation Neural Network Algorithm-Based Color Doppler Ultrasound Detection of Gestational Diabetes Mellitus and Perinatal Outcomes

In this work, the related risk factors and perinatal outcomes of pregnant women with gestational diabetes mellitus (GDM) were analyzed based on color Doppler ultrasound (CDU) diagnosis. Backpropagation (BP) algorithm-based CDU imaging algorithm (BPC) was constructed in this study and applied in CDU images of 80 pregnant women with GDM. Besides, amplitude and phase estimation (APES) and low-complexity adaptive beam (LCA) algorithms were introduced for comparison with BPC in turn. It was found that Dice similarity coefficient (96.44%), sensitivity (95.45%), and specificity (91.56%) of BPC were greater than those of APES (83.97%, 85.84%, 78.45%) and LCA (84.74%, 86.29%, 82.35%), while its running time (6.44 ± 1.39 s) was shorter than that of APES (11.87 ± 2.41 s) and LCA (13.76 ± 1.54 s) ( P < 0.05 ). Pregnant women in the experimental group (group B) were older than those in the control group (group A) ( P < 0.05 ). The pulsatility index (PI) and renal artery resistance index (RI) of fetuses in group B (0.95 ± 0.15) were higher than those of group A (0.57 ± 0.24) ( P < 0.05 ). In addition, pregnancy age, family history of hypertension, and abortion history were positively correlated with GDM ( P < 0.05 ). In conclusion, BPC could not only improve diagnosis accuracy in fetuses’ CDU images but also shorten calculation time. Pregnancy age, family history of hypertension, and abortion history were the related risk factors for GDM in pregnant women.

The value of color doppler ultrasonography in the diagnosis of impending ruptured abdominal aortic aneurysm

Objective: To study the value of color doppler ultrasonography (CDU) in diagnosis of impending ruptured abdominal aortic aneurysm (IRAAA). Methods: A total of 35 cases with IRAAA which were identified by CDU in our department from June 2014 to June 2019 were retrospectively analyzed. All the patients were detected by computed tomographic angiography (CTA). The types, length of the neck of aneurysm, largest diameter, thrombosis, involvement of common iliac artery and impending ruptured conditions were compared. The postoperative patients were followed-up by CDU and CTA (mean time was 2.6 months). Results: Among 35 patients, CDU diagnosed that 5 cases were pararenal types and 30 cases were infrarenal types. CTA showed that 4 cases were pararenal types and 31 cases were infrarenal types. The misdiagnosis rate of CDU was 2.9% (1/35). CDU showed that bilateral common iliac arteries were involved in 21 cases, right common iliac arteries were involved in 3 cases, and left common iliac arteries were involved in 2 cases. CTA detected the same results. There was no statistical difference between CDU and CTA for detection of the largest anteroposterior diameter, transverse diameter and the thickness of thrombosis (P values were 0.354, 0.310 and 0.865). There was statistical difference in the detection of the length of the aneurysm's neck (P=0.006). CDU showed 3 cases of focal wall discontinuity, 4 cases of hyperattenuating crescent sign, 3 cases of thrombus fissuration and 2 cases of saclike protuberance, which were consistent with the detection of CTA. CDU showed that locally thin wall of aneurysm was detected in the rest of 23 cases. CTA showed 2 patients were negative. The misdiagnosis rate of CDU was 5.7% (2/35). Three cases did not undergo surgery. Open repairs (OR) were performed in 5 cases. Endovascular aneurysm repairs (EVAR) were performed in 27 cases. The postoperative patients were followed up by CDU and CTA at 1 month, 3 months, 6 months and 12 months. All the artificial blood vessels and stents were patent. Endoleak was observed in 5 cases. Aneurysm sac thrombosis was found in the rest of the cases. Conclusions: CDU plays an important role in the analysis and diagnosis of the size, range, and the impending ruptured symptoms of the aneurysm. It provides a reliable basis for IRAAA screening, diagnosis and postoperative follow-up, and has important clinical value.

The application of Doppler ultrasonography in children′s transplant renal artery stenosis

Objective To explore the value of color Doppler ultrasonography in diagnosis of transplant renal artery stenosis(TRAS) of children. Methods The results of ultrasound examination and clinical data of 82 kidney transplant children with suspected TRAS were retrospectively analyzed. According to the results of the CTA, the enrolled children were divided into a stenosis group with 21 cases and a non-stenosis group with 61 cases. The differences of ultrasound hemodynamic parameters between the two groups were compared. The hemodynamic parameters and cutoff values of prediction of TRAS were determined according to the ROC curve, and the corresponding sensitivity and specificity were calculated. Logistic regression was used to screen TRAS independent predictors. Results Compared with the non-stenosis group, the peak systolic velocity (PSV) of the renal aorta, the renal aorta PSV/interlobular artery PSV (post PSV ratio) and acceleration time (AT) of interlobular artery in the stenosis group were significantly higher, but the PSV of the interlobular artery was lower (all P<0.05). Differences of indicators between the two groups can be used to predict TRAS. Through the ROC curve the peak systolic velocity of the renal aorta and the interlobular artery were 218.5 cm/s and 25.5 cm/s, respectively, the post PSV ratio was 7.2, and the AT of intervein arterial was 67.5 ms, the sensitivity and specificity were the highest, which could be used as the ultrasound screening threshold. The PSV of the interlobular artery can be used as an independent predictor of TRAS. Conclusions Analysis of hemodyamic parameters of transplanted kidney arteries by Doppler ultrasonography might be useful in predicting TRAS in children.

Objective To compare the diagnostic value of two-dimensional ultrasound and three-dimensional color Doppler ultrasonography combined with alpha-fetoprotein (AFP) and creatine kinase (CK) in the diagnosis of scar uterus and placenta previa implantation. Methods 120 cases of pregnancy delivery documented in our hospital from February 2013 to January 2017 were selected as the research object. All cases were divided into implantation group and non implantation group accorded to the pathological diagnosis. The implantation group of 44 cases were diagnosed as placenta previa implantation and the non implantation group of 76 cases were diagnosed as non placenta previa implantation. Two-dimensional ultrasound and three-dimensional color Doppler ultrasound diagnosis characteristic and effect in the two groups were recorded. The AFP, CK expression in the two groups were also detected. Results AFP and CK expression were detected in the serum levels of all pregnant women. The AFP and CK expression in the implantation group were (152.80±11.66)μg/L and (125.98±16.67)IU/L, significantly higher than non implantation group [(80.65±22.84)μg/L and (77.55±23.32)IU/L, P<0.05]. Ultrasonic diagnosis of placenta implantation in 39 cases, and non placenta previa implantation81 cases ; there were 38 cases of placenta accreta and 82 cases of non placenta previa implantation judged by AFP and CK expression; 43 cases of placenta previa implantatio, and 77 cases of non placenta previa implantation judged by ultrasound combined with AFP and CK. So the combined diagnostic sensitivity were significantly higher than that of single diagnostic sensitivity (P<0.05). The receiver operating characteristic (ROC) curve shows that the area under the curve of ultrasound is =0.879, AFP and CK=0.835, and the ultrasound was better than AFP and CK. Conclusions The two-dimensional ultrasound and three-dimensional color Doppler ultrasonography combined with AFP and CK in the diagnosis of scar uterus and placenta previa implantation can improve the diagnostic effect, and they have very good application values.

The efficacy of magnetic resonance imaging and color Doppler ultrasonography in diagnosis of salivary gland tumors.

Background and aims. Although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. This study aimed to evaluate the efficacy of magnetic resonance imaging (MRI) and color doppler ultrasonography parameters in the diagnosis and differentiation of benign and malignant salivary gland tumors.Materials and methods. In this cross-sectional study, color doppler ultrasonography and MRI were performed for 22 patients with salivary gland tumor. Demographic data as well as MRI, color doppler ultrasonography, and surgical parameters including tumor site, signal in MRI images, ultrasound echo, tumor border, lymphadenopathy, invasion, perfusion, vascular resistance index (RI), vascular pulse index (PI) were analyzed using Chi-square test, Fisher's exact test, and independent t-test.Results. The mean age of patients was 46.59±13.97 years (8 males and 14females). Patients with malignant tumors were older (P < 0.01). The most common tumors were pleomorphic adenoma (36.4%), metastasis (36.4%), and mucoepidermoid carcinoma (9%). Nine tumors (40.9%) were benign and 13 (59.1%) were malignant. The overall accuracy of MRI and color doppler ultrasonography in determining tumor site was 100% and 95%, respectively. No significant difference observed between RI and PI and the diagnosis of tumor.Conclusion. Both MRI and ultrasonography have high accuracy in the localization of tumors. Well-identified border was a sign of benign tumors. Also, invasion to adjacent structures was a predictive factor for malignancy.

Prevalence of deep vein thrombosis in patients with paraplegia caused by traumas

BACKGROUND: Deep vein thrombosis is a common disease among people who are immobilized. Immobility is inherent to paraplegia and leads to venous stasis, which is one of the factors covered by Virchow's triad describing its development. Trauma is the primary cause of paraplegia and is currently increasing at a rate of 4% per year. OBJECTIVE: To determine the prevalence of deep vein thrombosis in paraplegic patients whose paraplegia was caused by traumas, using color Doppler ultrasonography for diagnosis. METHODS: This was a cross-sectional observational study of 30 trauma-induced paraplegia patients, selected after analysis of medical records at the neurosurgery department of a University Hospital in Curitiba, Brazil, and by a proactive survey of associations that care for the physically disabled. The prevalence of deep vein thrombosis was analyzed using 95% confidence intervals. RESULTS: Spinal cord trauma was the cause of paraplegia in 29 patients. The most common cause of trauma was gunshot wounding, reported by 17 patients. Deep vein thrombosis was diagnosed by color Doppler ultrasonography in 14 patients in the sample. The most often affected vein was the posterior tibial, in 11 patients. The left lower limb was involved three times more often than the right. Edema was observed in 25 individuals, cyanosis in 14, ulcers in 8 and localized increase in temperature in 13. CONCLUSIONS: Deep vein thrombosis was prevalent, occurring in 46.7% of the patients.

Variacoes anatomicas dos vasos tibiais: diagnostico diferencial de trombose venosa profunda antiga pela ecografia vascular

CONTEXTO: Apesar de a ultrassonografia vascular com Doppler colorido (UVDC) ser confiável na avaliação de TVP em membros inferiores, situações como variações anatômicas das veias tibiais podem limitar o diagnóstico ou mesmo induzir a um resultado falso-positivo. OBJETIVO: Apresentar uma variação anatômica das veias tibiais posteriores potencialmente responsável por resultados falso-positivos no diagnóstico da TVP antiga pela UVDC. MÉTODOS: Foram revisados exames de UVDC em pacientes com suspeita de trombose venosa profunda de membros inferiores realizados no período de janeiro a dezembro de 2012. Nestes, foram observados a presença, o número e o trajeto das veias profundas, e suas respectivas artérias. Os casos suspeitos de variação anatômica nas veias tibiais posteriores foram revisados por outro ultrassonografista vascular, para confirmação dos achados. A variação anatômica com agenesia ou hipoplasia das veias tibiais posteriores foi considerada somente quando a artéria tibial posterior também não foi identificada em toda a extensão ou nos respectivos segmentos nos quais não foram visibilizadas as veias. RESULTADOS: Foram realizados 1458 estudos pela UVDC em pacientes com suspeita de TVP em membros inferiores. Em seis pacientes (0,41%), houve agenesia parcial ou completa das veias tibiais posteriores. Cinco pacientes tiveram avaliação unilateral e um bilateral, totalizando sete membros inferiores, três membros inferiores direitos e quatro esquerdos. CONCLUSÃO: Apesar de encontrada em apenas 0,41% dos casos, o conhecimento da agenesia das veias posteriores é útil, a fim de diminuir erros diagnósticos e resultados falso-positivos para TVP em pacientes com essas variações.

Validation of color Doppler ultrasonography for evaluating the uterine blood flow and perfusion during late normal pregnancy and uterine torsion in buffaloes

The aim of this study was to verify the efficacy of color Doppler ultrasonography for diagnosis of degree and duration of uterine torsion in buffaloes. In Assiut province/Upper Egypt, 65 buffaloes (37 with uterine torsion, 28 with normal late pregnancy) were examined clinically and using Doppler ultrasonography. The Doppler indices including resistance index (RI), pulsatility index (PI), time-averaged maximum velocity (TAMV), and blood flow volume (BFV) in the arteries ipsilateral to the uterine torsion (IPUT) and in arteries contralateral to the uterine torsion (COUT) were recorded. Methods of correction were documented along with dam and calf survival. Torsion was recorded postcervically with vaginal involvement in 35/37 (94.6%) of the cases. The degrees of uterine torsion were light and high in 9/37 (24.3%) and 28/37 (75.7%) of the cases, respectively (P = 0.001). Right uterine torsion was present in 36/37 (97.3%) of the cases (P = 0.0001). Pulsatility index, RI, TAMV, and BFV in IPUT and COUT did not differ significantly (P > 0.05) in normal late pregnancy. The PI and RI in IPUT were significantly higher (P < 0.01) than in COUT, and the TAMV and BFV in IPUT were less (P < 0.001) than that in COUT in uterine torsion. The PI and RI of torsion cases in IPUT were higher (P < 0.001) than that in normal pregnancy. Time-averaged maximum velocity and BFV in torsion cases were lower (P < 0.01) than that of normal pregnancy in IPUT. There was approximately 50% of RI and PI higher than in light degree uterine torsion in IPUT (P < 0.001). Consequently, TAMV and BFV were greatly lower (P < 0.0001) than that in light degree in IPUT. Pulsatility index and RI were positively correlated (r = 0.856; P < 0.001) with the duration and degree of the uterine torsion, and TAMV and BFV were negatively correlated (r = −0.763; P < 0.001). In all cases of uterine torsion the uterine flow velocity waveform showed high systolic flow and absence of early diastolic flow and poor uterine and placentomal blood perfusion. In conclusion, depicting blood flow within the middle uterine artery using color Doppler sonography could be helpful in correct diagnosis of duration and degree of uterine torsion and concurrently predicting the viability of the fetus and dam.
