Objective To explore the clinical application of spatio -temporal image correlation combined with multiplanar mode (STIC-MP) in the routine scanning of normal fetal heart ,and to provide evidence for the application of STIC in the routine scanning of fetal heart in second trimester .Methods One hundred pregnant women at 20-27 weeks′gestation were enrolled.The routine five views of normal fetal heart were examined and recorded by two-dimensional ultrasound,and the volume datasets were acquired with STIC.The time of picture storing and the fetal cardiac structures were recorded respectively .The quality of pictures obtained by both methods were compared by the scoring system .The imaging method of STIC-MP was explored and analyzed.Results Satisfactory gray-scale volume acquisitions were accomplished in all 100 cases.The quality of the four views(four chamber view,left outflow tract,right outflow tract,three vessel-trachea views) derived from volume datasets were comparable to that directly obtained from two-dimensional scanning.No significant difference of visualization rate ( χ2 =3.030,0.337,2.010,0.000,all P>0.05)was found between the STIC-MP(100/100,98/100,98/100,95/99 as 100.0%,98.0%,98.0%,96.0%)and two-dimensional(97/100,99/100,100/100,95/98 as 97.0%,99.0%,100.0%,96.9%).However,the difference of visualization rate was found in the stomach transverse view ( χ2 =9.776,P=0.001).The mean time for the examination and picture saving of fetal cardiac structures by STIC ,mean acquisition time was (1.17 ±0.52) min,which was much shorter than that by two-dimensional scanning (4.20 ±1.35) min (t=0.38,P<0.05).The mean time for obtaining the routine five views of fetal heart and analyzing by STIC and MP were (6.75 ±1.51) min,(1.35 ±0.30)min respectively,which was longer than (4.20 ±1.35)min and (0.83 ±0.22)min by two-dimensional ultrasound(t=11.75,11.75,both P=0.00).Conclusions STIC-MP simplifies the picture-gathering process,decreases the ultrasound exposure upon fetal heart obviously .No significant difference was found between the quality of the five views obtained from STIC-MP and two-dimensional ultrasound.The views of STIC-MP can satisfied the routine scanning of fetal heart ,although the interpretation time of STIC-MP was longer compared with two-dimensional ultrasound.There will be vital significance on the use of STIC in clinical application .

Objective To study the chemical components of Anemarrhenae Rhizoma;To establish a method to determine the content of vitexin;To compare the content difference of vitexin from Anemarrhenae Rhizoma before and after salt processing. Methods 70% ethanol extract of Anemarrhenae Rhizoma was separated and purified by silica gel column chromatography technique, and compound was identified by physicochemical properties and spectral data. HPLC was used with Ecosil column (4.6 mm×150 mm, 5μm), mobile phase of acetonitrile-0.2%acetic acid solution (14.5∶85.5), velocity of 1.0 mL/min, and determine wavelength of 340 nm. Results The compound was vitexin, a good linearity (r=0.999 8) in the range of 0.039 8-1.99μg. The average recovery rate was 98.02%, RSD=0.21%. Vitexin content was 0.008 5% in crude Anemarrhenae Rhizoma, 0.008 1% in processed products. Conclusion This is the first time separation of vitexin from Anemarrhenae Rhizoma. The method for content determination of vitexin is accurate, specific, and highly sensitive in the present experiment. Content of vitexin decreases slightly in processed products of Anemarrhenae Rhizoma compared with crude Anemarrhenae Rhizoma.

Objective To explore the ultrasonic imaging features of fetal craniocerebrum, and improve the recognizition on the normal structure and deformity of fetal craniocerebrum. Methods Fetal cranium was measured during 12～40 weeks of gestation, including biaparietal diameter(BPD),lateral ventricular width(LVW),cerebellomedullary cistern(CM), and nuchal translucency(NT) or nuchal fold thickness(NF). Results 18 cases of abnormal craniocerebrum were identified,nine cases of which were accompanied with other abnormalities, and fourteen of which were found during 16～28 weeks of gestation. All cases were proved by subsequent labor or induced labor. Conclusion Second-trimester is the best period of prenatal ultrasound diagnosis of fetal craniocerebrum.

OBJECTIVETo establish social stress induced depression-like model in mice of C57BL/6 strain, and to assess its reliability using differenf behavioral methods.

METHODSTotally 20 male mice of C57BL/6 strain were divided into the normal group and the stress model group by random digit table,10 in each group. Another 10 CD1 mice were subjected to social stress. Mice in the normal control group received no stress, while those in the model group received social stress for 10 successive days. Behavioral assessment was performed using social interaction test (SIT), the elevated plus-maze (EPM) test, tail suspension test (TST), respectively. Serum cortisol level was detected by ELISA to assess the reliability of the model.

RESULTSIn the social interaction test when the social target (CDI mice) was inexistent, mice in the normal control group spent longer time in the social interaction zone and less time in the corner zone (P < 0.05); mice in the model group spent less time in the social interaction zone and more time in the corner zone (P < 0.05). Compared with the normal group when CDI mice existed, mice in the model group spent less time in the social interaction zone and more time in the corner zone (P < 0.05). Compared with the normal control group, the total times for entry into open arms, close arms, and the maze were obviously reduced (P < 0.05), and the proportion of entering open arms was significantly reduced (P < 0.05) in the model group. In TST, the motionless time within the last 4 mm was prolonged in the model group (P < 0.05). The serum cortisol level in the model group was obviously elevated (P < 0.01).

CONCLUSIONSocial stress induced depression-like animal model in mice of C57BL/6 straineasquite reliable and possibly suitable to be used in integrative medicine research of combination of disease and syndrome model.
