Predictive value of the trans-perineal three-dimensional ultrasound measurement of the pubic arch angle for vaginal delivery

BACKGROUND Numerous variables are linked to the success of vaginal delivery,including the subpubic arch angle(SPAA)during labor,the importance of which has not yet been fully elucidated.AIM To examine the SPAA distributional characteristics and to ascertain SPAA’s ability to predict the type and duration of labor.METHODS We determined the SPAA and analyzed the corresponding data.We also evaluated the relationship between the SPAA and the mode of delivery and the duration of labor by regression.The present study comprised a total of 301 pregnant women who had given birth at Beijing Tiantan Hospital of the Capital Medical University between January and December of 2021.RESULTS Our analysis of 301 pregnant women revealed that the SPAA measured using three-dimensional trans-perineal ultrasound had a minimum angle of 81°and a maximum angle of 122.2°.The angle in the normal vaginal delivery group was greater than that in the labor cesarean group(P=0.000).The SPAA was a highly significant positive predictor of normal vaginal delivery(P=0.000)with an area under the curve of 0.782(P=0.000;95%CI:0.717-0.848).We found the length of the second stage of labor to be positively influenced by the SPAA using linear regression analysis(P=0.045).CONCLUSION The SPAA was a highly significant positive predictor of normal vaginal delivery.The length of the second stage of labor and normal vaginal birth were predicted by SPAA.

A three-dimensional environmental monitoring system for the production of marine gas hydrates

1.Objectives As about 99% of the natural gas hydrate (NGH)resources are stored on the seafloor,it is inevitable that in its process of exploration and production,there will be geohazards such as methane leakage,seabed subsidence,ecosystem damage and even landslide.Therefore,a set of integrated systems for environmental monitoring in the process of NGH production has been proposed in the consideration of environmental disasters that may arise in the process of hydrate production.

Intestinal ultrasound as a non-invasive tool to monitor inflammatory bowel disease activity and guide clinical decision making

Intestinal ultrasound(IUS)is a non-invasive,real-time,cross-sectional imaging tool that can be used at the point-of-care to assess disease activity in patients with Crohn’s disease or ulcerative colitis.IUS promotes quick and impactful treatment decisions that can modify disease progression and enhance patient compliance.This review will summarize the technical aspects of IUS,the evidence to support the use of IUS in disease activity monitoring,the comparison of IUS to current standard of care monitoring modalities such as colonoscopy and calprotectin,and the optimal positioning of IUS in a tight-control monitoring strategy.

Role of three-dimensional endoanal ultrasound in assessing the anal sphincter morphology of female patients with chronic proctalgia

AIM To assess the role of three-dimensional endoanal ultrasound (3D-EAUS) for morphological assessment of the anal sphincter of female patients with chronic proctalgia (CP). METHODS In this unmatched case control study, 30 consecutive female patients with CP and 25 normal women (control group) were enrolled. 3D-EAUS was performed in all subjects. Thickness and length of internal anal sphincter (IAS), thickness of puborectalis muscle (PR), length of the external anal sphincter (EAS) plus PR, and puborectalis angle were measured and compared between the two groups. RESULTS Patients with CP had significantly shorter IAS length and greater PR thickness, as compared to those in normal individuals (26.28 +/- 3.59 mm vs 28.87 +/- 4.84 mm, P < 0.05 and 9.67 +/- 1.57 mm vs 8.85 +/- 0.97 mm, P < 0.05, respectively). No significant between-group differences were observed with respect to IAS thickness and the EAS plus PR length (P > 0.05). Puborectalis angle in the CP group was significantly decreased, both in resting (88.23 degrees +/- 1.81 degrees vs 89.94 degrees +/- 2.07 degrees in control group, P < 0.05) and straining (88.47 degrees +/- 3.32 degrees vs 90.72 degrees +/- 1.87 degrees in control group, P < 0.05) phases, which suggest the presence of paradoxical contraction of PR in patients with CP. In the CP group, no significant difference in puborectalis angle was observed between the resting and straining phases (88.23 degrees +/- 1.81 degrees vs 88.47 degrees +/- 3.32 degrees respectively, P > 0.05). CONCLUSION The association of greater PR thickness and paradoxical contraction of PR with CP suggest their potential value as markers of CP.

Detection of Congenital Uterine Malformation by Using Transvaginal Three-dimensional Ultrasound

This study assessed the clinical application of transvaginal three-dimensional ultrasound （3D TVUS） in the diagnosis of congenital uterine malformation. A retrospective study was performed on 62 patients with congenital uterine malformation confirmed hysteroscopically and/or laparoscopically. The patients were subjected to transvaginal two-dimensional ultrasound （2D TVUS） and 3D TVUS. The accuracy rate was compared between the two methods. The accuracy rate of 3D TVUS was （98.38%, 61/62）, higher than that of 2D TVUS （80.65%, 50/62）. 3D TVUS coronal plane imaging could demon- strate the internal shape of the endometrial cavity and the external contour of the uterine fundus. It al- lowed accurate measurement on the coronary plane, and could three-dimensionally show the image of cervical tube, thereby providing information for the diagnosis of some complex uterine malformation. 3D TVUS imaging can obtain comprehensive information of the uterus malformation, and it is superior to 2D TVUS for the diagnosis of congenital uterine malformations, especially complex uterine anomaly.

Sequential transcatheter arterial chemoembolization,three-dimensional conformal radiotherapy,and high-intensity focused ultrasound treatment for unresectable hepatocellular carcinoma patients

The purpose of this study was to evaluate the outcome of patients with unresectable hepatocellular carcinoma（HCC） treated by sequential therapy of transcatheter arterial chemoembolization（TACE）,three-dimensional conformal radiotherapy（3-DCRT） and high-intensity focused ultrasound（HIFU）.From October,2005 to September,2010,120 patients with unresectable HCC received the sequential treatments of several courses of TACE followed in 2-4 weeks by 3-DCRT and then a single session of HIFU with a curative intent.The median tumor irradiation dose was 40 Gy.Tumor response,toxicity and overall survival rate were analyzed.Clinicopathologic factors affecting the primary technique effectiveness and overall survival rates were investigated by univariate analysis or multivariate analysis.All 120 HCC patients were followed up by the last follow-up time.Among these patients,hepatic toxicities due to treatment were notable in 9 cases.Gastrointestinal bleeding after the overall treatment occurred in 2 cases,leukopenia of grade III was detected in 1 case,radiation-induced liver disease（RILD） was observed in 2 patients,and first-and second-degree skin burn around the HIFU treatment zone were observed in 2 patients and 1 patient,respectively.Among 120 patients,23,83 and 14 cases achieved partial response,stable disease and progressive disease,respectively.The overall survival rates at 1 year,3 years and 5 years were 70%,35% and 15%,respectively,with a median survival time of 26 months.Both Child-Pugh liver function grading and radiation dose were determined to be independent predictors for overall survival revealed by the multivariate analysis.It is concluded that the sequential therapy of TACE,3-DCRT and HIFU is a promising therapeutic regimen for unresectable HCC.

Prenatal Diagnosis of Sirenomelia by Two-Dimensional and Three-Dimensional Skeletal Imaging Ultrasound

Summary： This study sought to evaluate the contribution of two-dimensional ultrasound （2D-US） and three-dimensional skeletal imaging ultrasound （3D-SUIS） in the prenatal diagnosis of sirenomelia. Be- tween September 2010 and April 2014, a prospective study was conducted in a single referral center using 3D-SU1S performed after 2D-US in 10 cases of sirenomelia. Diagnostic accuracy and detailed findings were compared with postnatal three-dimensional helical computed tomography （3D-HCT）, radiological findings and autopsy. Pregnancy was terminated in all 10 sirenomelia cases, including 9 singletons and I conjoined twin pregnancy, for a total of 5 males and 5 females. These cases of sirenomelia were deter- mined by autopsy and/or chromosomal examination. Initial 2D-US showed that there were 10 cases of oligohydranmios, bilateral renal agenesis, bladder agenesis, single umbilical artery, fusion of the lower limbs and spinal abnormalities; 8 cases of dipus or monopus; 2 cases of apus; and 8 cases of cardiac abnormalities. Subsequent 3D-SUIS showed that there were 9 cases of scoliosis, l0 cases of sacrococ- cygeal vertebra dysplasia, 3 cases of hemivertebra, 1 case of vertebral fusion, 3 cases of spina bifida, and 5 cases of rib abnormalities. 3D-SUIS identified significantly more skeletal abnormalities than did 2D-US, and its accuracy was 79.5% （70/88） compared with 3D-HCT and radiography. 3D-SUIS seems to be a useful complementary method to 2D-US and may improve the accuracy of identifying prenatal skeletal abnormalities related to sirenomelia.

Transcutaneous cervical esophagus ultrasound in adults: Relation with ambulatory 24-h pH-monitoring and esophageal manometry

AIM: To determine the gastroesophageal refl uxate in the cervical esophagus (CE) and measure transcutaneous cervical esophageal ultrasound (TCEUS) f indings [anterior wall thickness (WT) of CE, esophageal luminal diameter (ELD), esophageal diameter (ED)]; to compare TCEUS findings in the patient subgroups divided according to 24-h esophageal pH monitoring and manometry; and to investigate possible cut-off values according to the TCEUS f indings as a predictor of gastroesophageal refl ux (GER). METHODS: In 45/500 patients, refl uxate was visualized in TCEUS. 38/45 patients underwent esophagogastroduo denoscopy (EGD), 24-h pH monitoring and manometry. RESULTS: The 38 patients were grouped according to 24-h pH monitoring as follows: Group A: GER-positive (n = 20) [Includes Group B: isolated proximal refl ux (PR) (n = 6), Group C: isolated distal reflux (DR) (n = 6), and Group D: both PR/DR (n = 8)]; Group E: no refl ux (n = 13); and Group F: hypersensitive esophagus (HSE) (n = 5). Groups B + D indicated total PR patients (n = 14), Groups E + F refl ux-negatives with HSE (n = 18), and Groups A + F refl ux-positives with HSE (n = 25). When the 38 patients were grouped according to manometry fi ndings, 24 had normal esophageal manometry; 7 had hypotensive and 2 had hypertensive lower esophageal sphincter (LES); and 5 had ineffective esophageal motility disorder (IEM). The ELD measurement was greater in group A + F than group E (P = 0.023, 5.0 ± 1.3 vs 3.9 ± 1.4 mm). In 27/38 patients, there was at least one pathologic acid refl ux and/or pathologic manometry fi nding. The cut-off value for ELD of 4.83 mm had 79% sensitivity and 61% specificity in predicting the PRbetween Groups B + D and E (AUC = 0.775, P = 0.015). CONCLUSION: Visualizing refluxate in TCEUS was useful as a pre-diagnostic tool for estimating GER or manometric pathology in 71.1% of adults in our study, but it was not diagnostic for CE WT.

Three-dimensional psychological guidance combined with evidencebased health intervention in patients with liver abscess treated with ultrasound

BACKGROUND Liver abscess is a common clinical liver disease mainly caused by suppurative bacteria or amoebae,with early clinical signs of chills,high fever,jaundice,and other symptoms.Establishing its early diagnosis is difficult,which may lead to misdiagnosis.AIM To observe the effects of psychological guidance combined with evidence-based health intervention in patients with liver abscess treated with ultrasound.METHODS A total of 120 patients with bacterial liver abscess admitted to our hospital from May 2018 to February 2021 were selected and divided into groups according to their intervention plan.RESULTS After the intervention,Self-Rating Depression Scale,Self-Rating Anxiety Scale,Self-Perceived Burden Scale(SPBS),and quality of life scores(physical functioning,role physical,bodily pain,general health,vitality,social functioning,role emotional,mental health)were lower than before the intervention in the two groups.The observation group had lower negative sentiment,SPBS,and quality of life scores than the control group.In the observation group,31 and 24 patients had good and general compliance,respectively,with a compliance rate of 91.67%,which was significantly higher than that in the control group.The observation group had significantly lower total incidence of incision infection,abdominal abscess,hemorrhage,and severe abdominal pain than the control group.CONCLUSION Three-dimensional psychological guidance combined with evidence-based health intervention in treating liver abscess can reduce patients’burden and negative emotions,improve patient compliance and quality of life,and reduce complications.

Antidiastole Value of Three-dimensional Ultrasonography and Power Doppler between Uterine Parenchyma Lumps and Endometrial Cancer:A Retrospective Study

Sometimes endometrial polyps,submucosal myomas,and endometrial cancer show similar findings under ultrasonography.The aim of this study was to assess the antidiastole value of blood flow parameters using three-dimensional(3D)power Doppler ultrasonography angiography(PDA)between endometrial cancer and uterine parenchyma lumps.The data of the blood flow indices in 3D-PDA including the vascularization index(VI),flow index(FI),and vascularization flow index(VFI)in 40 patients with endometrial cancer and 41 patients with uterine parenchyma lumps(endometrial polyps and submucosal myomas)were retrospectively analysed and compared utilizing Virtual Organ Computer-aided AnaLysis(VOCAL)software.The results showed that all the blood flow parameters(VI,FI,VFI)were significantly higher in women with endometrial cancer than in those with uterine parenchyma lumps(P<0.001).The area under the curve of ROC of VI,FI,and VFI was 0.98,0.84,and 0.97,respectively.Thus,the best predictor of endometrial carcinoma was VI with a sensitivity of 97.0% and a specificity of 91.0%.The optimal cutoff value of VI was 4.06%.Our data demonstrated that all of the blood flow signal parameters(including VI,FI,and VFI)in 3D power Doppler ultrasonography had significant antidiastole values between endometrial cancer and uterine parenchyma lumps to assist clinicians in properly diagnosing patients.

Experimental and measured research on three-dimensional deformation law of gas drainage borehole in coal seam

Using self-researched gas drainage borehole stability dynamic monitoring device, three-dimensional deformation characteristics of borehole under steady vertical load were researched experimentally and systematically. This research indicated that under the action of steady loading, the mechanical deformation path of the simulated gas drainage borehole is gradually complicated, and the decay of the borehole circumferential strain is an important characterization of the prediction and early warning of borehole instability and collapse. The horizontal position of borehole occurs compressive strain, and the vertical of which occurs tensile strain under the action of vertical stress. At the initial stage of loading, the vertical strain is more sensitive than that in the horizontal direction. After a certain period of time, the horizontal strain is gradually higher than the vertical one, and the intersection of the borehole horizontal diameter and the hole wall is the stress concentration point. With the increase of the depth of hole, the strain shows a gradual decay trend as a whole, and the vertical strain decays more observably, but there is no absolute position correlation between the amount of strain decay and the increase in borehole depth,and the area within 1.5 times the orifice size is the borehole stress concentration zone.

Three-dimensional imaging of the uterus:The value of the coronal plane

Advent in three-dimensional(3D) imaging technology has seen 3D ultrasound establish itself as a useful adjunct complementary to traditional two-dimensional imaging of the female pelvis. This advantage largely arises from its ability to reconstruct the coronal plane of the uterus, which allows further delineation of many gynecological disorders. 3D imaging of the uterus is now the preferred imaging modality for assessing congenital uterine anomalies and intrauterine device localization. Newer indications include the diagnosis of adenomyosis. It can also add invaluable information to delineate other endometrial and myometrial pathology such as fibroids and endometrial polyps.
