Objective To evaluate the value of tomographic ultrasound imaging(TUI)in the fetal heart screening.Methods One hundred and ten volume datasets acquired from normal fetal heart in the second trimester with spatio-temporal image correlation(STIC) were evaluated offline with TUI. The Bmode and CDFI static images as well as the dynamic loops of one cardiac eycle could be reviewed simultaneously. The visualizing rate and ultrasonic scores of the 4 chamber view,outflow tracts and 3 vessels (and trachea)view obtained from TUI and routine ultrasonography for fetal heart screening were respectively compared. Results Among all 110 cases,the visualizing rate of 4 chamber view,outflow tracts and 3 vessels(and trachea) view were respectively 100%(67),88.9%(45),80.0%(45),84.4%(32)in Bmode and 100%(33),86.2%(25),50.0%(14),100%(4)in CDFI under the same fetal Dositi.n.No significant differences of the visualization rate were found between TUI and routine screening either in Bmode or in CDFI(P>0.05). The median score of 4 chamber view of TUI in B-mode was little higher than that in routine screening,while the right outflow tract of screening in CDFI significantly higher than that of TUI(P<0.05). Conclusions The visualizing rates and qualities of TUI are sufficient for fetal heart screening offline as well as routine ultrasonography online in second trimester.

Objective To assess the value of tomographic ultrasound imaging (TUI) for prenatal analysis of the relative orientation of fetal heart and great arteries. Methods Volume datasets acquired from 12 patients of transposition of the great arteries (TGA) and 13 normal fetal heart were evaluated offline with TUI. The aortic valves (AV) and pulmonary valves (PV) were respectively showed on the two parallel slices. According to the pivot point in the middle of the PV in one slice, the relative orientation of the AV on another slices were analyzed. Results In the 12 patients of TGA confirmed postnatally, 7 were concomitant with single ventricle anomaly, AV was on the anterior-right orientation of the PV in 5, and was relatively on the anterior and anterior-left orientation in other 2 of them.In the remained 5 with seeming normal 4 chamber view, AV was found on the anterior-right of the PV in 3, and was relatively on the anterior and upright orientation.in other 2 patients. In 13 normal fetuses, TUI showed that all AV located on the posterior-right orientation to the PV. Conclusion TUI can provide detailed spatial information of the great arteries both in normal and abnormal fetal heart. It may be a convenient and veracious tool for prenatal exploring the morphology of the great arteries.

BACKGROUND:The currently published literatures about Tuina manipulation for lumbar disc herniation include clinical observations, retrospective study and summary of clinical experience, which have shortcomings in the study design, choice of cases and outcome measures. Reviews may enrol randomized and intended references, and has no analysis or evaluation on the quality of involved literatures, leading to the bias and subjective views.
OBJECTIVE:To research the application laws of Tuina manipulation for treating lumbar disc herniation through literature analysis within 10 years.
METHODS:The key words of“lumbar disc herniation, traditional Chinese medicine, Tuina, manipulation, massage, rehabilitation, poking channels, point pressing, palpating pressing, and finger pressing”in Chinese were used to search the literature about Tuina manipulation in treatment of lumbar disc herniation within recent 10 years published in the Wanfang database, Vip database and CNKI database. The top 20 manipulations of Tuina for lumbar disc herniation were and statistical analyzed with hierarchical clustering statistical method.
RESULTS AND CONCLUSION:The hierarchical clustering analysis results showed that, Tuina manipulations for lumbar disc herniation are as fol ows:(1) manipulations acted on soft tissue, including rol ing, holding, pushing and pressing;(2) manipulations acted on acupuncture point, including Urinary Bladder Meridian of Foot-Taiyang acupuncture points (Shengshu, Dachangshu, Guanyuanshu, Zhibian, Chengfu, Weizhong, Chengshan and Kunlun), Gal Bladder Meridian of Foot-Shaoyang acupuncture points (Huantiao and Yanglingquan), Yaoyangguan point in Du Meridian, Zusanli point in Stomach Meridian of Foot-Yangming, and tender points;(3) manipulations acted on human bones and joints, including waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method. The findings indicate that the potential application laws of Tuina manipulation for treating lumbar disc herniation are given priority to pressing acupuncture points (Urinary Bladder Meridian of Foot-Taiyang acupuncture point, Gal Bladder Meridian of Foot-Shaoyang acupuncture point, Du Meridian, Stomach Meridian of Foot-Yangming acupuncture point and tender points), at the same time companied with manipulations acted on soft tissue (rol ing, holding, pushing spinal method), and bones and joints (waist inclined pul method, waist back-stretching method, pelvic traction method and straight-leg raising method).

UNLABELLEDOBJECTIVE To study the in vitro effect and mechanism of Ginkgo biloba Extract 50 (GBE50) for inhibiting beta-amyloid (Abeta)-induced oxidative stress in rats' hippocampal neurons.
METHODSThe primary hippocampal neurons were cultured in vitro and divided into 4 groups, i. e. the normal control group (Ctrl), the Abeta group, the propanediol control group (PDO), and the six GBE50 concentrations groups (5, 10, 25, 50, 100, and 200 microg/mL). Excepted the Ctrl group, neurons were induced to oxidative stress by 20 gmolLAbeta25-35. The MTT and fluorescent probes labeling were used to observe the effect of GBE50 with different concentrations on the cell viability and the generation of intracellular reactive oxygen species (ROS) in neurons. Furthermore, Western blot was used to detect the cytoplasmic/total cytochrome C (Cyto C) ratio and total intracytoplasmal Cyto C, and the effect of the expression of oxidative stress-related protein Cyto C and activated Caspase-3 in three GBE50 concentrations groups (25, 50, and 100 microg/mL).
RESULTSCompared with the Ctrl group, the cell vitality was obviously lowered and intracellular ROS generation significantly increased after induction of 20 micromol/L Abeta25-35 (both P < 0.05). Compared with the Abeta group, the cell vitality was evidently improved after treated with different GBE50 doses. Except for 10 microg/mL, the cell vitality could be obviously elevated along with increased drug concentrations (P < 0.05). Meanwhile, the intracellular ROS generation decreased significantly in each GBE50 dose groups (P < 0.05). Abeta could increase the cytoplasmic/total Cyto C ratio and enhance the activated Caspase-3 expression significantly (P < 0.05). Compared with the Abeta group, among the three concentrations of GBE50, the Cyto C ratio was obviously lowered in the 100 microg/mL GBE50 group (P < 0.05), and the expression of activated Caspase-3 significantly decreased in 50 microg/mL and 100 microg/mL GBE50 groups (P < 0.05).
CONCLUSIONS20 micromol/L Abeta25-35 could induce the generation of intracellular ROS in hippocampal neurons. GBE50 could inhibit Abeta induced intracellular oxidative stress of neurons through lowering the cytoplasmic/total Cyto C ratio and inhibiting the activation of apoptosis protein Caspase-3 expression.
