Objective To observe pelvic floor muscle′s contraction in women with the second and full term natural parturition by intelligent ultrasonic examination. Methods Ninety-five postpartum women who underwent natural parturition and post-partum check (6-9 weeks after delivery) in Henan Provincal People′s Hospital were recruited in this study from Jul to Dec 2018. Fifty-four puerpera were first parturition and 41 were second parturition. The morphology of urogenital hiatus was observed during both rest and contract maneuver by real-time 3D ultrasound. Several parameters were measured by intelligent ultrasound, such as hiatal area, anteroposterior diameter, transverse diameter, and the thickness of puborectalis muscles, and the D-values of all parameters were calculated in different maneuver. Meanwhile, the strength of pelvic muscle in two groups were measured and the ultrasonic diameters and muscle strength were compared. Results The hiatal area, anteroposterior diameter, transverse diameter, and the thickness of bilateral puborectalis muscles between first natural parturition and second natural parturition during rest maneuver were (15.92±2.76)cm2 vs (16.65±2.63)cm2, (40.93±5.63)mm vs (40.27±6.21)mm, (55.54±6.05)mm vs (57.92±5.27)mm, (7.03±1.51)mm vs (7.44±1.23)mm, (7.49±1.44)mm vs (7.44±1.44)mm, there was no statistical difference(P>0.05). During contract maneuver, these data were (11.76±2.62)cm2 vs (12.09±2.78)cm2, (37.57±5.46)mm vs (37.18±4.71)mm, (42.21±5.69)mm vs (43.03±7.13)mm, (8.92±1.54)mm vs (8.87±1.23)mm, (8.90±1.60)mm vs (9.30±2.71)mm, there was no statistical difference(P>0.05). The D-values of all diameters were (4.16±2.38)cm2 vs (4.43±2.70)cm2, 3(1.00, 5.00)mm vs 1(1.00, 5.25)mm, (13.33±6.07)mm vs (14.41±6.54)mm, (1.90±1.78)mm vs (1.68±1.31)mm, 1(0.48, 2.40)mm vs 1.25(0.20, 2.13)mm, there was no statistically significant difference between two groups (P>0.05). The non-eligibility rate of typeⅠmuscle fiber strength in two groups were 65% vs 68%(35 vs 28) and typeⅡmuscle fiber strength were 74% vs 79%(40 vs 32), there was no statistically difference between two groups (P>0.05). Conclusions In comparison to the primary and full term natural parturition women, there is no significant reduction of the pelvic floor muscle′s contraction by intelligent ultrasund in second and full term natural parturition women without abnormal pregancy history and complications. This could provide theoretical basis for the choice of the mode of second parturition and the rahabilitation of postpartum.

Objective To investigate the correlations between the labor process and the elastography parameters, and to explore the correlations among the elastography parameters. Methods A total of 48 pregnant women in the late periods of pregnancy in Beijing Hospital from November 10, 2018 to January 30, 2019 were recruited prospectively. Elastography was performed to measure several elastographic parameters including the cervical length (CL), elasticity contrast index (ECI), hardness ratio (HR), internal orifice uterus(IOS) and external orifice uterus(EOS). They were followed up to delivery, and were divided into normal group and prolonged group according to the time duration of the first stage of labor. The correlation between the parameters and the time duration of the first stage of labor, as well as the relationships among the parameters were evaluated. Results Among the 48 pregnant women, 35 cases were delivered by the vagina, 13 by cesarean section, 4 of whom were due to the prolongation of the first stage of labor and the other 9 cases for other reasons. The values of the CL and HR in normal group were significantly lower than that in prolonged group (P=0.004, 0.02). The ECI in the normal group was significantly higher than that in the prolonged group (P=0.046). Both the IOS and EOS in the normal group were higher than those in prolonged group without no significant difference(P>0.05). For the 35 women who underwent cervical elasticity assessment before labor and finally delivered vaginally, the duration of the first stage of labor was negatively correlated with cervical ECI (r=-0.415, P 0.05). Conclusions The ECI of cervical tissue measured by cervical elastography can be used to semi-quantitatively evaluate the maturity of the cervix, it has potential value in predicting the labor duration and guiding clinical decision-making.

Objective To validate the role of color Doppler ultrasound in an animal model to detect early heterotopic ossification (HO) after brain-traumatic/burn/tenotomy. Methods Forty-four rats were randomly divided into two groups. Rats in experimental group (n=22) were operated to build brain-traumatic/burn/tenotomy model and others in control group (n=22) underwent only skin incision injury. Color Doppler ultrasound, X-ray film examination at 2, 3, 4, 6, 8 and 10 weeks post-injury were performed to follow up the progression of HO in both groups respectively. Histology was used to confirm bone formation. Results In the experimental group, disorder structure with a hypoechoiccore in treated Achilles tendon was visualized using color Doppler ultrasound in the 2nd week. Additional tiny hyperechoic foci were observed in the 3rd week, which increased in the fourth week and fused into a mineralized island in the sixth week. No obvious abnormality was found in control group at the aforementioned time point. X-ray could detect heterotopic bone tissue in the sixth week in the experimental group but not in the control group. X-ray and HE stainning had confirmed bone formation in the tenth week in the experimental group.

Objective To observe the change of the left ventricular(LV) wall shear stress (WSS) using vector flow mapping (VFM) in different segments at each phase of diastolic period among normal subjects. Methods From August 2018 to March 2019, 200 healthy volunteers selected from the Physical Examination Center of the Second Affiliated Hospital of Harbin Medical University were recruited. The WSS values of LV segments at the same and at different phases[isovolumic relaxation period(D1), rapid filling period(D2), slow filling period(D3), atrial contraction period(D4)] in diastole were measured and analyzed. Results ①The relationships of the WSS of LV different segments at the same phase of diastolic period: The WSS values of anterior septum, posterior septum and posterior wall during D1, and the WSS values of posterior septum, posterior wall and inferior wall during D2 showed basal>middle>apical segments, the differences were statistically significant (all P<0.05). ②The changes of the WSS values of LV different segments during diastolic period: During D1-D2-D3-D4 period, the absolute values of WSS in anterior septum, posterior septum, anterior wall, lateral wall and inferior wall showed an increasing-decreasing-increasing trend. During D2-D3-D4 period, the absolute values of WSS in the posterior wall showed a decreasing-increasing trend. During D1-D2-D3-D4 period, the absolute values of WSS in the apical segment of anterior septum, basal and middle segments of posterior septum, basal, middle and apical segments of anterior wall, basal segment of lateral wall, the middle and apical segments of posterior wall, basal and middle segments of inferior wall all showed an increasing-decreasing-increasing trend, the difference was statistically significant (all P<0.05). Conclusions The LV WSS in different segments at the same phase or in the same segment at the different phases in diastole exhibit a regular change and is consistent with the LV hemodynamic changes, which indicates that WSS can quantitatively reflect the hemodynamic changes of the LV in normal subjects.

Objective To investigate the feasibility of three dimensional(3D) printing fetal heart from spatio-temporal image correlation (STIC) volume-rendered data. Methods Eight fetuses with normal heart and 3 fetuses with confirmed cardiac anomalies identified by two-dimensional echocardiography from February to May 2019 in Renmin Hospital of Wuhan University were prospectively enrolled in this study. All the fetuses underwent two-dimensional (2D) echocardiography and STIC technology examination. The 3D volume images of fetal heart were post-processed by Mimics software to create images of the fetal heart in standard tessellation language format(STL). The STL file was output to the 3D printer and the 3D printing models of fetal heart and great vessels were obtained. In the process, the numerical values of each index of fetal hearts were measured from 3D digital model, 3D printing models and routine echocardiography images, respectively. The accuracy of 3D modeling was assessed by comparing the measured values of the model with the measured values of the source data. Results In all the fetuses, STIC volume data of the fetal heart were successfully reprocessed and printed out, the anatomical structure and vascular course could be visually displayed. It showed no significant difference in all the heart size parameters between 3D digital model, 3D printing models and routine echocardiography images (all P>0.05). Moreover, the size parameters were concordant well between the two methods, all of the data points fell within the limits of agreement.

Objective To evaluate the clinical value of color Doppler ultrasound(CDUS) combined with vascular enhancement technology(VET) in diagnosis of iliac vein compression syndrome(IVCS). Methods From Jan 2016 to Oct 2018, 252 patients with the lower extremities chronic venous diseases(CVD) were selected in the Second Hospital of Hebei Medical University. The ipsilateral iliac veins of the affected limbs were examined by CDUS, VET and the combined diagnosis of IVCS before X-Ray venography(XRV). Iliac vein diameter stenosis ratio(DSR)>50% in transverse section was the criterion of ultrasound diagnosis of IVCS. The stenosis site of iliac vein and indirect signs of IVCS, such as presence of collateral circulation and the retrograde flow of internal iliac vein were recorded. The cases, which had the same results in CDUS, VET and both and XRV, were divided into IVCS group and non-IVCS group. The results of XRV were taken as the gold standard, the diagnostic efficiency of the above 3 methods in diagnosis of IVCS was calculated. The cases identically diagnosed by the most effective ultrasonic method and XRV were divided into DVT group and non-DVT group according to the deep vein thrombosis in lower limbs. In the non-DVT group, there were five groups of C2-C6 on the basis of the CEAP clinical grades of CVD in lower extremity. The relationship between IVCS and different CEAP clinical grades were analyzed. The locations of common iliac vein stenosis and collateral circulation formation and internal iliac vein reverse flow were evaluated for the diagnosis of the IVCS. Results ①XRV diagnosis of IVCS was used as the gold standard. Compared with CDUS and VET alone, the sensitivity and specificity of CDUS combined with VET was the highest(all P 0.05). ④For the proportion of the iliac vein stenosis sites, the prevalence of the primary section of left common iliac vein was much higher than those of the primary section of right common iliac vein and the middle-distal sections of bilateral common iliac veins(all P 0.05). ⑤In IVCS group, which had the same results of CDUS combined with VET and XRV, there were statistical differences in the positive rate of collateral circulation and the retrograde flow of internal iliac vein(χ2=6.717, P=0.010), and the former is higher than the latter. Conclusions CDUS combined with VET has a higher diagnostic efficiency for IVCS than VET or CDUS alone. The presence of IVCS is closely related to DVT of lower extremities, but not related to clinical class of CEAP. The most common site of IVCS is the initial segment of the left common iliac vein. The presence of collateral circulation can be used as indirect indicators for the diagnosis of IVCS.

Objective To investigate the application value of shear wave elastography(SWE) in assessing the degree of hepatics fibrosis in children with biliary atresia before Kasai portoenterostomy. Methods From January 2017 to January 2018, 49 cases of children in Hunan Children′s Hospital with highly suspected biliary atresia in clinical were collected. The stiffness of the lower segment of right anterior lobe of the liver in all cases was assessed using SWE in 3 days before Kasai portoenterostomy. Pathological results of liver tissue specimens from the lower edge of the right liver during the surgery was taken as the gold standard. The correlation between the liver stiffness and the hepatics fibrosis was analyzed using Spearman correlation analysis. The receiver operating characteristic (ROC) curves were created to assess the area under curve (AUC), the best cutoff value, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the liver stiffness in diagnosing hepatocirrhosis. Results All of the 49 cases were confirmed by surgery and pathology. According to the stages of hepatics fibrosis, 5 cases were in stage S2, 23 cases in stage S3, 21 cases in stage S4, and no cases of stage S0 and S1. Spearman correlation analysis showed that the correlation coefficient between the liver stiffness and the stages of hepatics fibrosis was 0.779(P<0.001). The area under the curve of the liver stiffness in diagnosing cirrhosis was 0.914. When the cutoff value was 14.45 kPa, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 85.7%, 89.3%, 85.7%, 89.3%, 87.8%, respectively. Conclusions The liver stiffness measured by SWE is positively correlated with the stages of hepatic fibrosis, and the performance of SWE in the diagnosis of cirrhosis is remarkable. SWE can be used to evaluate the stages of hepatics fibrosis in children with biliary atresia before Kasai portoenterostomy.

Objective To investigate the echocardiographic characteristics, pathological anatomy and genetic abnormality of congenital absent semilunar valves in first trimester. Methods Eleven cases of congenital absent semilunar valve fetus diagnosed at 11-13+ 6 weeks of gestation in Guangxi Magernity & Child Healthcare Hospital from December 2014 to December 2018 were analyzed. The characteristics of echocardiography and the abnormal microanatomy of cardiac tissue after labor induction was compared. Results The crown-lump length of the 11 fetus was 46-74(62.0±9.2)mm, and nuchal translucency thickness(NT) was 2.4-10.4 (6.4±2.6)mm. The NT of 10 cases were greater than 3.0 mm. Color Doppler flow imaging revealed that biphasic bidirectional flow in the aortic arch and/or pulmonary artery at the 3VT view( "to-and-fro" ) in those 11 cases, and pansystolic turbulence and pandiastolic reflux spectrum were showed on spectral Doppler. Among them, there were 10 cases of " stealing type" , including 2 cases of isolate absent aortic valves, 3 cases of absent pulmonary valves and 5 cases of absent both aortic and pulmonary valves; and all the 10 cases had secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed that 4 cases with Trisomy 13 syndrome, 3 cases with Trisomy 18 syndrome, 1 case with 22q11.2 deletion, 1 case with 12q24.32q24.33 deletion and 1 case was normal. Pathological anatomy revealed enlarged heart in 8 cases, isolate absent aortic valves in 2 cases (1 case complicated with pulmonary atresia, absence of ductus arteriosus and thymus), absent pulmonary valves in 3 cases, absent both aortic and pulmonary valves in 3 cases, relics of semilunar valves in 3 cases. And 2 cases of absent pulmonary valves and 3 cases of absent both aortic and pulmonary valves with short and thick ductus arteriosus. Only 1 case was congenital absent semilunar valve in " non-stealing type" without secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed 22q11.2 deletion, and there were relics of semilunar valves in the pathological anatomy. It also combined with tetralogy of Fallot and absence of ductus arteriosus. Conclusions In first trimester, congenital absent semilunar valves are more common as " stealing type" . The echocardiographic features of congenital absent semilunar valves are the " in-out sign" of aorta arch and/or pulmonary artery and biphasic spectrum in spectral Doppler. Trisomy 13 syndrome and trisomy 18 syndrome significantly increased the risk of congenital absent semilunar valves in " stealing type" in first trimester.

Objective To investigate the current basic situation of ultrasound machines of ultrasound departments in Shanghai medical institutions, and to provide the basis for making management policy in order to promote medical quality. Methods Questionnaire surveys about ultrasound machines and service ability including producing countries of ultrasound machines, the number of ultrasound machines, using years of ultrasound machines, yearly workload and the yearly number of patients that each ultrasound machine accepted were made in 2013 and 2018, respectively. Statistical results were compared between the two surveys. Results Compared with 2013, the share of imported ultrasound machines declined in 2018 (82% vs 91%). Compared with 2013, the number of ultrasound machines in Shanghai medical institutions had increased by 31% in 2018 (2 123 vs 1 617). The occupancy rate of ultrasound machines in tertiary hospitals was the highest (tertiary hospitals 40%, secondary hospitals 25%, primary grade hospitals 20%, and private hospitals 15%). Compared with 2013, the proportion of ultrasound machines that have been used for more than 10 years increased (9% vs 4%), the yearly workload of ultrasound examination had increased by 46% (19.82 million person-time vs 13.59 million person-time). Tertiary hospitals bored the highest proportion of the workload (tertiary hospitals 51%, secondary hospitals 35%, primary grade hospitals 4%, and private hospitals 10%). Currently, the number of ultrasound machines per 10, 000 people in Shanghai was 1.14. The yearly number of patients that each ultrasound machine accepted had increased by 11% (9300 person-time vs 8400 person-time in 2018). Conclusions The scale of ultrasound departments in Shanghai medical institutions has been developing. Brand localization of ultrasound machines is improving. However, the renewal ability of ultrasound machines still needs to be improved. The workload of ultrasound department is getting heavier. Hierarchical diagnosis and treatment is unbalanced.
