ABSTRACT
@#In order to guarantee the quality of traditional Chinese medicines (TCMs), the crystallization transformation of complex extracts of TCMs and the influence of solid form on their physicochemical properties were studied.The extract of total flavonoids from Pueraria lobata was taken as a model.Crystallization transformation happened when lofting under different conditions, and the intrinsic dissolution tests were carried out.It was found that humidity was the key factor to induce crystallization of total flavonoids from Pueraria lobata.The greater the wettability was, the more the crystallization was.The dissolution rate of total flavonoids from Pueraria lobata with the most crystallization amount significantly decreased by 96.51% compared to the sample without crystallization.After further simulating the preparation process of total flavonoids from Pueraria lobata, it was found that the wet granulation process with introduced water would also lead to crystallization and reduced dissolution rate.As for all crystallization samples, there was an inversely proportional relationship between the dissolution rates and the amount of crystallization.The risk of crystallization existed both in the storage and preparation process of TCM extracts.Crystallization would significantly affect the dissolution rate, and thus the quality of TCM products.In this study, the crystallization transformation of amorphous complex TCM extracts was discovered, and the effect of the crystallization transformation on its dissolution behavior was systematically studied, which provides a new research idea for assuring the quality of TCM products and promoting the improvement of TCM preparation level.

ABSTRACT
Objective: To observe the clinical effect of acupuncture plus occupation therapy for fine motor functions in children with spastic cerebral palsy. Methods:A total of 80 cerebral palsy kids with fine motor dysfunction were allocated into two groups by envelop, 40 cases in each group. Cases in the control group were treated with occupation therapy. Based on the therapy given to the control group, cases in the treatment group were supplemented with acupuncture at the points of the three yang meridians of hand. The treatment was done every other day and 10 times for a course. There was a 15-day interval between two courses, and 3 courses in total. The therapeutic efficacies were evaluated using Peabody developmental motor scale 2 (PDMS-2) and modified Ashworth scale (MAS) before and after treatment. Results:After treatment, the standard score for grasping (Grs), standard score for visual-motor integration (Vis), fine motor quotient (FMQ) and modified Ashworth scale (MAS) were significantly improved in both groups (P<0.05). The improvement in the treatment group was more obvious than that in the control group (P<0.01). Conclusion:Acupuncture plus occupation therapy can achieve better effect than occupation therapy alone in improving fine motor functions of upper limbs in cerebral palsy kids.
ABSTRACT
OBJECTIVE@#To evaluate the superiority, feasibility and clinical signifi cance of the four-dimensional spatio-temporal image correlation (STIC) in detection of the right ventricle function of fetus.@*METHODS@#Th e STIC dynamic images of 180 normal fetal hearts at 24+0 to 37+6 weeks of gestation were obtained by the three-dimensional (3D) probe. Th e post-process evaluation was done off -line with the virtual organ computer-aided analysis (VOCAL) software. The computer recorded the right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), and then calculated the right stroke volume (RSV), the right cardiac output (RCO) and the right ejection fraction (REF). RCO was standardized by biometric measurements obtained at prenatal screening, including head circumference (HC), abdominal circumference (AC), femur length (FL) and estimated fetal weight (EFW).@*RESULTS@#The overall successful rate in image acquisition was 83.89% and the repeatability was favorable. After the standardization of fetal biometric parameters (HC, AC, FL) and the right ventricle function indexes (RVEDV, RVESV, RSV), RCO was increased with the gestational age while the REF and RCO/EFW fluctuated within a certain range.@*CONCLUSION@#STIC technique can accurately and objectively measure the fetal ventricular volume and it might be a potential strategy in the clinical assessment of the fetal cardiac function.

ABSTRACT
Objective To investigate the diagnosis of the diseases that presented with childhood chronic cerebellar ataxia.Method The clinical data of 15 children with chronic cerebellar ataxia were studied,including the clinical features,laboratory results and neuroimaging aspect.Results Of the 15 children with chronic cerebellar ataxia,3 cases had chronic progressive cerebellar ataxia diagnosed as ataxia telangiectasia,and neuroimaging finding that indicated mild to marked cerebellar atrophy.The others 12 cases had non-progressive cerebellar ataxia,2 cases of them had Joubert syndrome,characterized by delayed motor function and speech,lower limbs ataxia and cerebellar vermis hypoplasia; 10 cases had ataxic cerebral palsy with delayed motor skills,9 of them had mental retardation and verbal problem.Of the 10 children with ataxic cerebral palsy,7 cases had cerebellar hemispheric atrophy by computer tomography (CT) or MRI,while the other 3 cases had no positive finding in cerebellum by MRI,but 2 of whom were found reduced metabolism in cerebellar neuron during the test of positron emission tomography and CT.Comparson with the scores in the gross motor function measure (GMFM) and developmental quotient (DQ) of 5 domains (adaption,gross motor,fine motor,language and social development) in Gesell developmental Schedules before and after the rehabilitation approach:the totaI scores in GMFM after the treatment (56.42 ± 15.65) was significantly higher than that of before traatment (44.15 ±20.41) (t =-3.121,P ＜0.05),while the DQ of gross motor after the treatment (28.27 ± 14.65) was sigrificantly lower than that before treatment (35.23 ± 17.23) (t =2.75,P ＜ 0.05).The other 4 domains before the treatment were 37.47 ± 14.47,37.06 ± 11.51,40.69 ± 12.10 and 40.41 ± 15.79,and had no remarkable change after the treatment (39.44 ±16.29,35.96 ±10.76,40.26 ±14.20 and 38.61± 11.95) (allP＞0.05).Conclusions Children with chronic cerebellar ataxia presented as hypotonia with delayed motor function,and ususlly had inherent cerobellum abnormalities,without matter structure or function of the neuron.Chronic ataxia is an important symptom in genetic or metabolic disease,and a systematic approach may enhance diagnostic accuracy.
ABSTRACT
Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P＜0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.
ABSTRACT
Objective To assess the application of automated four-dimensional (4D) volume color Doppler ultrasonography in normal fetal heart screening. Methods Four-dimensional volume color Doppler was acquired at the level of four chamber view level in 120 fetuses from 18 to 23 weeks of gestation. Three diagnostic planes including color Doppler information were retrieved by automated multiplanar imaging from the 4D volumes. The left ventricular outflow view (cardiac plane 1), the right ventricular outflow view (cardiac plane 2) and ductal arch view (cardiac plane 3) were acquired. Tomographic ultrasound imaging (TUI) was added to display all the three diagnostic planes. The data were then analyzed to determine whether cardiac planes 1-3 were displayed correctly in each volume. Results Automated 4D volume color Doppler ultrasonography displaying rate of cardiac plane 1, cardiac plane 2, cardiac plane 3 were 100%, 96.67% and 91.67%, respectively. Cardiac plane 1 was displayed at least three TUI plane, cardiac plane 2 was displayed at least two TUI plane, and cardiac plane 3 was displayed at least two TUI plane. Conclusion It is possible to acquire important planes of the fetal heart with automated 4D volume color Doppler ultrasonography and the visualization rate of the three diagnostic planes is fine.
ABSTRACT
Objective To discuss the method and skill of prenatal diagnosis of fetal isolated pulmonary stenosis and thus to improve prenatal diagnostic ability. Methods The data of 18 fetuses diagnosed as isolated pulmonary stenois were reviewed and the ultrasonic characters of each section were analysised. Results Five of the 18 cases were confirmed as pulmonary stenosis by autopsy and 12 cases were confirmed by echocardiography after birth. One case was confirmed as pulmonary atresia by echocardiography after birth. Reversed blood flow in arterial duct was detected at the ductal arch section in all the cases and right atrial enlargement,right ventricular myocardial hypertrophy, tricuspid regurgitation, foramen ovale enlargement, reduced activity of foramen ovale valve were detected in partial cases. Conclusions It is important that reversed blood flow in arterial duct and in the two main artery could be observed at the ductal arch section and the three vessel section respectively. Ductal arch section,ventricular outflow tracts section and the three vessel section are very important in the diagnosis of fetal isolated pulmonary stenosis.
