Terahertz waves have unique properties and advantages, which makes it gain increasing attention and applications in the biomedical field. Burns is a common clinical trauma. Since the water-sensitive and non-destructive characteristics of terahertz, terahertz imaging techniques can be used to detect burns. So far, terahertz imaging technology in the assessment of burn injuries has been developed from ex vivo to in vivo, and high-resolution images can be obtained through the gauzes and plasters. In this paper, we mainly introduces the application of terahertz imaging technology and development in the assessment of burn injuries.

Purpose To explore the value of high frequency convex ultrasound probe in the diagnosis of ovarian tumor in infants and young children. Materials and Methods Sixty-nine infants and young children with ovarian tumor were examined with high frequency convex ultrasound probe, and the ultrasound findings were analyzed. Results Out of 69 cases, 45 had tumors on the right side of ovary and the rest 24 on the left side;27 cases of simple cyst, 24 cases of benign teratoma, 9 cases of borderline teratoma, 3 cases of serous cystadenoma, 3 cases of mucous cystadenoma, 3 cases of yolk sac tumor;24 accompanied with torsion or necrosis. The ultrasound of ovarian tumor presented the following features:polycystic structures were common;the strong echo posterior acoustic shadow was not obvious; no specific manifestation was shown to distinguish benign from malignant tumors. Doppler ultrasound of tissues around the tumor was significant in detecting ovarian tumor torsion and necrosis. Conclusion High frequency convex ultrasound probe can provide clear images and distinct dissection information, which is beneficial in diagnosis and differential diagnosis of ovarian tumor in infants and young children.

Objective To analyze the ultrasound findings of urinary calculi caused by melamine. Methods The urinary system of totally 5337 children were examined with high frequency convex ultrasound probe,the characteristics of the images were analysed. CT plain scan method was used when ultrasound result was in difficulty. Results There were 360 cases with calculus in the 5337 children. In the 360 cases, unilateral calculus was in 92 cases, bilateral calculus in 48, bladder stone in 3, urethra stone in 1, kidney calcium deposition in 2, suspicion stone in 214 cases, urinary obstruction in 28 of them. The size of the stones ranged from 3 mm×2 mm to stag-horn calculus. Conclusions The urinary calculi caused by melamine is sandy stone. Ultrasound result is equivocal in the disease, CT plain scan can be a method of choice. High frequency convex probe provides more clear images, more evident adminstrative levels of anatomise than general abdominal probe does. It is beneficial for diagnosing and differential diagnosing of these diseases.

Objective To explor the ultrasonography methodology of the fetal ductus arteriosus.Methods Based on the fetal four-chamber sight, the characteristic ultrasound images were observed by moving probe,such as "V-shape" sign,"three-finger" sign,"Z-shape" sign and"hockey-handle" sign making up of the ductus arteriosus and the nearby structures were observed by moving probe. The inner diameter,the systole flow velocity,the diastole flow velocity and the resistance index of the ductus arteriosus via the "V-shape" sign section were measured. Results Among the 365 normal fetus cases,355 "V-shape" sign cases,237 "three-finger" sign cases,298 "Z-shape" sign cases and 331 "hockey-handle" sign cases were identified. The inner diameter of the fetal ductus arteriosus increases gradually with the growth of the gestational weeks and the flow velocity increases gradually too, while the resistance index had no obvious variation with the growth of the gestational weeks. Conclusions According to the characteristic ultrasound images, such as "V-shape" sign, "three-finger" sign, "Z-shape" sign and "hockey-handle" sign, the fetal ductus arteriosus can be identified promptly.

Objective To explore the value of ductus arteriosus in ultrasound diagnosis of fetal congenital heart disease by echocardiography. Methods The fetal echocardiography was performed with three segments diagnosis method. According to the fetal position, the ductus arteriosus was examined in different sections which include the V shape sign section formed by ductus arteriosus and right pulmonary artery,the V shape sign section formed by ductus arteriosus and the gorge of aortic arch,the three fingers sign section formed by ductus arteriosus,left and right pulmonary artery,the Z shape sign section formed by left pulmonary artery, ductus arteriosus and the gorge of aortic arch. The flow velocity and the inner diameter of the ductus arteriosus were measured. Results Thirty-one cases with congenital heart disease were evaluted. Thirteen cases were approved by autopsy. Among those fetus, 4 cases went with ductus arteriosus stenosis and they all accompanied with right heart obstructing disease,3 cases went with dilated ductus arteriosus and they all accompanied with left heart obstructing disease. Retrograde were explored in 2 fetus. The flow velocity of 5 fetus ductus arteriosus were higher than the normal fetus and 4 cases of them with right heart obstruction, 1 cases with left heart obstruction. Five fetal ductus arteriosus were normal. One fetal ductus arteriosus was absent. Conclusions Assessant of ductus arteriosus by echocardiography is an important content in screening fetal congenital heart disease. It can help us to diagnose quickly.

Objective To explore the inhibitory effects of sulfated oligosaccharides PI-88 on the heparanase protein expression of human esophageal squamous cancer cell (ESCC) line TE-13, and to explore the effects of growth, angiogenesis and heparanase protein expression on ESCC xenografts of nude mice. Methods TE-13 cells were cultured and divided into three groups:group A (control group), group B (15 mg/L PI-88) and group C (30 mg/L PI-88). Heparanase protein expression of TE-13 cells was measured by Western blot assay after being cultured for 36 h. The ESCC suspension was injected subcutaneously in 10 BALB/c/nu mice to build up ESCC xenograft model. The model mice were divided randomly into observation group and control group (5 mice per group). The mice in observation group received 40 mg/(kg·d) PI-88. The mice in control group only received the same volume of saline at the same time. Both PI-88 and saline were daily administrated for 14 days. Every 2 days,the volume of xeongrafts were measured and the mice were executed at the 14th day. CD34 immunohistochemical staining was used to detect the micro vessel density (MVD) of xenografts. Western blot assay and immunohistochemical staining were used to detect the heparanase protein expression of xenografts. Results The heparanase protein expressions of TE-13 cells were significantly decreased in group B and group C than those of group A (P<0.001), with a kind of PI-88 dose-dependent manner. The volume, MVD and heparanase protein expression of xenografts were significantly lower in observation group than those of control group (P<0.05). Conclusion The heparanase protein expression in TE-13 cells can be inhibited by PI-88 in vitro and vivo. Furthermore, the growth and angiogenesis of ESCC xenografts were also inhibited by PI-88.
