Objective To investigate the diagnostic value of the craniocerebral magnetic resonance angiography(MRA) in adult moyamoya disease.Methods 20 adult patients with Moyamoya disease were examined by DSA,MRI and MRA.Results DSA showed that the ending of internal carotid artery system were stenosis or occlution,and the fog-like blood vessel networks at base of skull were observed in the 20 patients.By MRI,the cerebral ischemical changes were found in 11 cases,intracerebral hamrrahge was found in 9 cases.MRA showed that cerebral artery were stenosis or obstruction in all of the 20 patients,16 cases(80%) with the fog-like blood vessel net in the thalamus-basal ganglia region.The detectable rate of abnormal cerebral basal vascular network was no statistical difference between DSA and MRA.Conclusions MRA can provide more information of cerebral artery straitness or obstruction and fog-like blood vessel net in the adult patients with Moyamoya disease,and without hammerless.MRA has a very importent value of diagnosis in the adult moyamoya disease.

Objective To compare the effect of active compression-decompression cardiopulmonary resuscitation(ACD-CPR) with standard- cardiopulmonary resuscitation(S-CPR) on ventricular function in a canine ventricular fibrillation model. Methods Ventricular fibrillation was induced in anesthetized and instrumented canine. Twenty-four dogs were randomly assigned to either ACD-CPR group or S-CPR group.After 4 minutes of untreated VF,two-dimension echocardiography was used to evaluate the left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction (LVEF) of every canine of the two groups when they were undergoing cardiopulmonary resuscitation. Results During ventricular fibrillation, both ACD-CPR group and S-CPR group showed decreased LVEDV compared with pre-ventricular fibrillation, but not statistically significant( P ＞0.05).LVEDV was increased in ACD-CPR group compared with S-CPR group, but not statistically significant (P＞ 0. 05). Both ACD-CPR group and S-CPR group showed significantly increased LVESV compared with pre-ventricular fibrillation,of which the difference was statistically significant ( P ＜0. 001). Both ACD-CPRgroup and S-CPR group showed significantly decreased LVEF compared with pre-ventricular fibrillation,of which the difference was statistically significant (P ＜0. 001). LVEF was increased in ACD-CPR group compared with S-CPR group,of which the difference was statistically significant ( P = 0.019). Conclusions Compared with S-CPR,ACD-CPR resulted in higher LVEF.

Objective To summarize imaging features of Kallmann syndrome (KS) in children and to improve diagnostic level of the disease.Methods The imaging manifestations of 13 patients with clinically proved KS were retrospectively studied.MRI of rhinencephalon and left wrist X-ray examinations were performed in all the 13 children.Ultrasound of abdomen and pelvis was implemented in the 8 of 13 patients.Results All the patients had abnormalities of olfactory system.Bilateral olfactory bulbs and tracts were absent in 9 patients.Unilateral olfactory bulbs and tracts were absent in 4 patients,in which contralateral olfactory bulbs and tracts were hypoplastic.These patients presented 2 aplastic,17 hypoplastic and 7 normal olfactory sulci.Anterior pituitary was hypoplastic in 3 patients.Bone age showed retardation in 6 of 13 patients.Bilateral testicles were small in all the 8 cases by ultrasound.Conclusions Aplastic or hypoplastic olfactory bulbs and tracts and sulci are seen in children with KS.Anterior pituitary dysplasia is present in part of patients and bone age backward happens in approximate half of the children.

Objective To evaluate the value of systemic ultrasound examination in prenatal diagnosis of fetus skeletal system anomaly combined with chromosomal abnormalities. Methods In 12 146 patients examined by systemic ultrasound in Sichuan Provincial People's Hospital from 2006 to 2013, 21 fetus with skeletal system abnormalities and chromosomal abnormalities were included in the study. And the correlation between skeletal system abnormalities and chromosomal abnormalities in fetus was evaluated. Results This study involves 21 cases of abnormal fetal skeletal system combined with chromosomal abnormalities. Among them, there were 5 cases of trisomy-21, 11 cases of trisomy-18, 3 cases of trisomy-13, 1 case of [46, XYt (6, 9)], and 1 case of (46, XY, 6 q-). In 19 cases, other system malformations were found, including nervous system abnormalities, facial deformity, cardiac structural abnormalities and intrauterine retardation. In the rest 2 cases, skeletal system abnormalities were the only structural malformation detected on prenatal ultrasound examination. Conclusion Systemic ultrasound can't only detect fetal skeletal system abnormalities but also provide clues for specific chromosomal abnormalities, which was useful in optimizing prenatal diagnosis.

Objective To investigate the correlation between ABCD2 scores and vertebrobasilar artery stenosis in patients with posterior circulation transient ischemic attack (TIA).Methods The patients with posterior circulation TIA who performed cerebral angiography were enrolled in the study,and their ABCD2 scores and imaging data were analyzed.Results A total of 108 patients with posterior circulation TIA were enrolled.There were significant differences in the main trunk stenosis degree of vertebrobasilar artery with different ABCD2 scores in patients with posterior circulation TIA (P =0.005).The overall degree of stenosis increased with the increase of ABCD2 score (P =0.000).After adjustment for other vascular risk factors,ABCD2 score had significant predictive ability for whether had posterior circulation stenosis (odds ratio [OR]1.771,95％ confidence interval [CI] 1.234-2.542; P =0.002) and moderate to severe stenosis (OR 2.083,95％ CI 1.336-3.176; P =0.001).Its receiver operating characteristic area under the curve was 0.693(95％ CI 0.586-0.800) and 0.755 (95％ CI 0.661-0.849) respectively.When the ABCD2 score was ≥3,the sensitivity and specificity of predicting posterior circulation stenosis were 62.6％ (95％ CI 53.4％-71.7％) and 70.6％ (95％ CI62.0％-79.1％) respectively,and the sensitivity and specificity of predicting posterior circulation stenosis ＞ 50％ were 78.7％ (95％ CI 70.9％-86.4％) and 67.5％ (95％ CI58.7％-76.3％) respectively.Conclusions In patients with posterior circulation TIA,the stenosis degree of vertebrobasilar arterial trunk increases with the increase of ABCD2 score.In a certain extent,ABCD2 score may predict whether the main trunk of the posterior circulation has stenosis and whether has moderate to severe stenosis.

Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .

Aim To evaluate the effects of R-Salbutamol(R-Sal)on the contraction of isolated tracheal strips and lung parenchyma strips in guinea-pig,induced by Histamine(His).Methods Tracheal strips and lung parenchyma strips of guinea-pig in vitro were prepared,and the dilatory effect on shrinkage reaction of isolating specimens induced by His were measured before or after the administration of R-Sal in doses of 10-8,10-7,10-6 mol?L-1,with fix-doses pharmacology methods.The inhibitory effect was compared with that of Sal(10-6 mol?L-1).Results His could induce the contraction of isolated strips in guinea-pig in a dose-dependent manner,and R-Sal could significantly inhibit this shrinkage of lung parenchyma induced by His.in a dose-dependent manner.R-Sal was much more efficient than Sal(P

Objective To investigate the significance of the Children's Rehabilitation Management System (ICR 2.0) for occupational therapy (OT) for cerebral palsy (CP). Methods 60 children with CP were divided into group A (n=30) and group B (n=30). The group A accepted OT program assisted with ICR 2.0, and the group B accepted OT program drawn by therapists experientially. They were assessed with Enjoji infant development scale and Fine Motor Function Measure (FMFM) before and 3 months after treatment. Results There was no significant difference in development months and the fine motor between 2 groups before treatment (P>0.05). Both the development and fine motor improved after treatment (P<0.001), and improved more in the group A than in the group B (P<0.05). Conclusion ICR 2.0 assisted OT program can further improve the recovery of children with CP.
