Objective:To explore the feasibility and influencing factors of E-cervix cervical elasticity analysis technology in analyzing normal cervical function during non pregnancy.Methods:213 women who underwent vaginal ultrasound examination in the Ultrasound Department of Foshan Maternal and Child Health Hospital from May 2019 to November 2019 were selected as the research objects. Taking the median sagittal section of the cervix as the initial section, the E-cervix technology software package was started to automatically obtain the elastic contrast index (ECI), hardness ratio (HR), cervical strain rate (IOS), cervical strain rate (EOS), cervical strain ratio (IOS/EOS) and cervical length (CL). The relationship among age, menstrual cycle, BMI index, birth history, delivery mode and elastic parameters were compared.Results:There was no correlation between the elastic parameters and age, and there was no significant difference among different age groups ( P>0.05); there was no significant difference in the elastic parameters of cervical tissue in menstrual period, proliferative period and secretory period ( P>0.05); there was no significant difference in the elastic parameters of underweight, normal and overweight ( P>0.05); CL was positively correlated with body mass index (BMI) ( r=0.225, P<0.05), there was no correlation between other parameters and BMI ( P>0.05); there was no significant difference between the elastic parameters of patients with and without birth history ( P>0.05); the CL of women with cesarean section [(34.22±4.96)mm] was higher than that of women with natural birth [(29.03±4.14)mm] ( P<0.05), and the other parameters had no statistical significance ( P>0.05). Conclusions:The elastic parameters of cervix obtained by E-cervix technique are not affected by age, BMI, menstrual period, reproductive history and delivery mode, and can be used for quantitative evaluation of cervical function.

Objective To study etiology screening role of transrectal ultrasonography in male obstructive azoospermia infertility.Methods The clinical data of 328 cases who suspected of being obstructed sperm disease were retrospectively analyzed.TRUS detection was conducted,at the same time,the sperm amount,sperm and semen pH,pure berries quantitative,neutral sugar alpha glycosidase enzymes quantitative,elastic hard protease were tested.Results In 328 cases with male obstructed no sperm,by TRUS detection results,216 cases (65.8%) could find the causes,ejaculatory duct expansion,seminal vesicle gland lesions,prostate midline cyst were the top three causes respectively;112 patients(34.2%) had no obvious abnormal ultrasonic testing.Sperm was not seen in semen of obstructive azoospermia patients and semen pH < 7,pure berries sugar quantitative and quantitative value neutral alpha glycosidase enzymes were very low,hard elastic protease was low.Conclusion The main causes of obstructive azoospermia were ejaculatory duct expansion,seminal vesicle gland lesions,prostate midline cyst,sperm TRUS detection used for diagnosis of high sensitivity,and easy to operate,noninvasive,and combined with seminal plasma biochemical examination,the diagnostic effect is much better.

Objective To explore the clinical value of color Doppler ultrasoundcardiogram in the screening of congenital heart disease(CHD) in neonates. Methods 29568 neonates were examined by color Doppler ultrasoundcardiogram. Results 369 CHD patients were identified, the overall incidence of CHD was 12.48‰. The incidence in 2009 or 2010 were significantly higher than those in 2005 or 2004 ( all P < 0. 05 ), the mean incidence of four years from 2007 to 2010 was significantly higher than that from 2003 to 2006( 13.78‰ vs 10.17‰,P <0. 01 ). Of 369 CHD cases,most of them were ventricular septal defect( occupied 48.24% ) ,next was atrial septal defect( occupied 44.17% ). Conclusion The incidence of CHD ascended rapidly from 2003 to 2010,and color Doppler ultrasoundcardiogram was an important method to diagnose CHD in newborns.

Objective:
To explore the related factors of subependymal hemorrhage (SEH) and cerebral hemodynamic changes.
Methods:
From October 2012 to October 2017, 200 cases of children with subependymal hemorrhage diagnosed by ultrasound in our department of pediatrics were selected as the observation group , and a total of 150 children who were admitted to the Department of Pediatrics in the same period due to craniocerebral diseases and other serious diseases were selected as control group. The independent risk factors of the children in the observation group were analyzed, and the difference of the maximum systolic blood flow velocity (SV), the diastolic maximum flow velocity (DV), the systolic and diastolic velocity ratio (S/D), the resistance index (RI), and the pulsatile index (PI) were compared between the two groups.
Results:
Neonatal asphyxia, preterm birth, acidosis, neonatal respiratory distress syndrome (NRDS), patent ductus arteriosus and coagulation dysfunction were independent risk factors for subependymal hemorrhage. The bleeding side SV and DV of the observation group were higher than those of the control group, with statistically significant difference (
