Combination of high-frequency ultrasound and virtual touch tissue imaging and quantification improve the diagnostic efficiency for mild carpal tunnel syndrome.

Background: Carpal tunnel syndrome (CTS) is the most common entrapment symptom in the peripheral nerves. High-frequency ultrasound (HFUS) is widely used in the diagnosis of CTS. Virtual Touch Tissue Imaging and Quantification (VTIQ), which provides more information about the hardness of organization, is used to diagnose CTS.

Evaluation of Skeletal Muscle Microcirculation and Reserve Function of the Type 2 Diabetes with Contrast-Enhanced Ultrasonography.

Objective: This study aimed to discuss clinical application value of contrast-enhanced ultrasonography on lesion skeletal muscle microcirculation and arterial perfusion reserve in type 2 diabetes mellitus and complicated microvessels.

Methods: Patients in the control group, type 2 diabetes mellitus (DM) group, diabetic microangiopathy (DM + MC) group underwent contrast-enhanced ultrasonography before and after temporary arterial occlusion to observe blood perfusion of gastrocnemius muscle; draw the time-intensity curve of arteriole, muscular tissue, and venule, and obtain perfusion parameters such as contrast agent arrival time and contrast agent transit time. Blood glucose, insulin, insulin resistance index, and relevant blood rheology parameters were measured.

Three-dimensional sonographic minute structure analysis of fetal cerebellar vermis development and malformations: utilizing volume contrast imaging.

Purpose: To obtain three-dimensional ultrasonic (3D US) structural details and biometrics of the fetal cerebellar vermis and evaluate the value of developmental and malformation identification.

Methods: The 3D US minute structure of the fetal cerebellar vermis in mid-sagittal view was detected in normal fetuses (n = 438; 16-41 weeks). Biometric sizes were measured to establish the stage-specific norms and reproducibility analysis.

Prenatal Evaluation for Detection of Anorectal Atresia: Value of Ultrasound.

Objectives: To investigate the applicability and value of ultrasound (US) in the diagnosis of anorectal atresia.

Methods: Between January 2008 and January 2016, we prospectively evaluated 63,101 fetuses (gestational age, 20-38 weeks), including low- and high-risk populations using 2-dimensional US scans. An abnormal imaging finding was defined as an anal canal diameter of less than the 95% confidence interval (small anal canal) of the normal range or the absence of an anal canal and rectum.

[cts of prenatal exposure of 850-1900MHz mobile phone on the expression of PCNA and DCX in dentate gyrus of offspring rats].

Objective: To evaluate the effect of prenatal mobile phone exposure on the expression of proliferating cell nuclear antigen (PCNA) and doublecortin (DCX) in dentate gyrus of offspring rats.

Methods: The rat model of prenatal mobile phone exposure was established and there were three groups including control group, short term maternal exposure group and long term maternal exposure group(=6). From pregnant day 1 to day 17, pregnant rats in long term and short term maternal exposure group were exposed to an mobile phone in talking mode for 6 h/d and 24 h/d, respectively.

Prenatal Ultrasound Evaluation of the Position of Conus Medullaris for the Diagnosis of Tethered Cord Syndrome.

To determine the conus distance between the end of the conus medullaris and the distal end of the last vertebral body in healthy fetuses with various gestational ages using ultrasonography for its diagnostic value in tethered cord syndrome (TCS). This retrospective study included 540 healthy and 8 autopsy-confirmed TCS fetuses. Ultrasonographic measurement of the conus distance was performed when the fetus was in a prone position within the spine in the near field at 14 to 41 weeks of gestational age.

Evaluation of gastric blood supply in diabetic patients with gastroparesis by contrast-enhanced ultrasound.

Objective: Improvement in regional blood flow has been shown to ameliorate diabetic gastroparesis. We compared the gastric blood supply in patients with diabetes with gastroparesis with that in healthy subjects, by using contrast-enhanced ultrasound (CEUS).

Methods: 30 healthy subjects and 40 patients with diabetic gastroparesis were enrolled.

Application of contrast-enhanced ultrasonography and ultrasonography scores in rheumatoid arthritis.

Objective: To investigate diagnostic value of ultrasonography scores (US) and contrast-enhanced ultrasonography (CEUS) in evaluating rheumatoid arthritis (RA) activity.

Methods: 39 patients with RA were included and the metacarpophalangeal, proximal interphalangeal, wrist, elbow and knee joints of them were examined by high frequency ultrasound. The severe joints and the related indexes (synovial thickness, synovial blood flow, joint effusion and bone erosion) were exposed.

Reference ranges of fetal spleen biometric parameters and volume assessed by three-dimensional ultrasound and their applicability in spleen malformations.

Aim: The aims of this article are to establish three-dimensional ultrasonographic nomograms of normal fetal spleen size and to evaluate the clinical application value.

Methods: An observational, cross-sectional study was performed on 455 women with a normal singleton pregnancy between 18 and 38 weeks' gestational age (GA). Fetal spleen volume was measured using three-dimensional ultrasound equipped with virtual organ computer-aided analysis, and biometric parameters were assessed in multiplanar mode to create reference ranges to GA.

Evaluation of gastric emptying in diabetic gastropathy by an ultrasonic whole stomach cylinder method.

In order to explore the accuracy of ultrasonic whole stomach cylinder measurement (UWSCM) in the evaluation of gastric emptying, we measured the gastric emptying times (ET) at 25% (T1), 50% (T2) and 75% (T3) of healthy subjects and patients with diabetic gastropathy by UWSCM and scintigraphy. The ET of patients were compared with their clinical symptom scores. We found that the ET measured by UWSCM showed no significant difference with scintigraphy (p > 0.

Maternal hypoxia increases the susceptibility of adult rat male offspring to high-fat diet-induced nonalcoholic fatty liver disease.

Exposure to an adverse intrauterine environment increases the risk for adult metabolic syndrome. However, the influence of prenatal hypoxia on the risk of fatty liver disease in offspring is unclear. The purpose of the present study was to evaluate the role of reduced fetal oxygen on the development and severity of high-fat (HF) diet-induced nonalcoholic fatty liver disease (NAFLD).

Intermittent maternal hypoxia has an influence on regional expression of endothelial nitric oxide synthase in fetal arteries of rabbits.

Background: Maternal hypoxia induces sustained fetal adaptations associated with changes in gene expression. We hypothesized that intermittent maternal hypoxia has an influence on regional expression of endothelial nitric oxide synthase (eNOS) in fetal arteries of New Zealand White rabbits.

Methods: Timed-pregnant New Zealand White rabbits (term = 30 ± 1 d) were randomly assigned to a normoxic control group (n = 5) or a hypoxia group (12% O2, n = 5) during days 10-29 of pregnancy.

The effect of fetal congenital heart disease on in utero urine production rate.

Objectives: To evaluate the influence of congenital heart disease (CHD) or congestive heart failure (CHF) on fetal urine production rate (UPR) and to establish normal reference intervals.

Methods: A cross-sectional study was performed on normal fetuses (n = 314) and on fetuses with CHD (n = 49). CHD cases were divided into groups on the basis of heart function as defined by Huhta score: with CHF (n = 11) and without CHF (n = 38).

Ultrasound probe pressure but not maternal Valsalva maneuver alters Doppler parameters during fetal middle cerebral artery Doppler ultrasonography.

Objective: To determine the effects of increased ultrasound probe pressure and maternal Valsalva maneuver (VM) on the middle cerebral artery (MCA) Doppler ultrasonography in fetuses.

Methods: A total of 120 healthy pregnant women in second and third trimesters were enrolled in the study. MCA blood flow was measured by pulsed Doppler sonography in 60 fetuses (24 and 40 weeks' gestation) before and after the application of increased ultrasound probe pressure.
