Objective To explore the accuracy and feasibility of dual-source CT(DSCT)in evaluating the left ventricular function compared with echocardiography.Methods 30 cases of coronary heart disease were continuously collected in our hospital ,and dual-source CT and echocardiography were examined in a week.Left ventricular function parameters (LVEDV,LVESV,LVSV)were measured,and paired sample t test was compared to show whether there was any difference between the two methods,Rates betweengroups were compared with Chi-square test,Pearson correlation analysis method was applied to calculate the correlation between the two methods.Results There was no statistically significant difference for LVEDV,LVESV,LVSV,LVEF parameters between the two methods (t test,P >0.05).By Pearson test,the correlation coefficient was r=0.770-0.938(P <0.05),in which the high relation between the two methods was showed.Conclusion A strong accuracy of dual-source CT in evaluating left ventricular function is demonstrated.Dual-source CT angiography is a noninvasive assessment of coronary tree,whereas the analysis of the left ventricular parameters provides additional information of cardiac function without further radiation exposure or scan time,which can provide a more intuitive and system information for clinical.

The system of meridians and acupoints in the traditional Chinese medication (TCM) builds up a complex network. We analyze the features and properties of the system of meridians and acupoints as a complex network based on knowledge of TCM and mathematics. The system shows some important features of complex networks such as the small-world effect and the scale-free property. A preliminary discussion on the robustness of the meridian system as a complex network, and the biomedical functions of such robustness is also given.

Objective To explore the engrafted effect of NSCs combined with OECs on the motor function repair of hindlimbs in rats subjected to spinal cord transected injury.Methods The NSCs and OECs were isolated from the Transgenic Green Fluorescent Protein(GFP) embryo mouse' hippocamp and neonatal mouse' olfactory bulb.Rats were divided into NSCs group,OECs group and co-transplantation group as well as control group.The recovery of posterior limb motor function in rats subjected to spinal cord transected injurywas evaluated by the BBB locomotion score respectively in each weekend among eight weeks.This was followed by a histochemiscal observation to know the engrafted cells survival and migration in the spinal cord of host under the fluorescence microscope.Results The NSCs and OECs cells survived and migrated in the spinal cord of transplantation groups:the motor functional improvement of hindlimb in rats was seen in all cell transplanted groups;NSCs group,OECs group and co-transplantation group demonstrated a significant increase than that of control group at 3 and 4 weeks post operation(P 0.05).Conclusions The engrafted NSCs,OECs and co-transplantation can improve partly the motor function recovery of hindlimb in rats at 3 to 4 weeks following cord transection;The OECs group and co-transplantation have better effects than that of NSCs group,but there is no obvious difference between the OECs group and co-transplantation group at observed time point in this investigation.

Objective : To learn the effects of cassia seed extract,ginkgo biloba leaf extract,salvia miltiorrhiza extract and red yeast rice compounds on blood lipid level of rats with hyperlipidemia. Methods : The model of hyperlipidemia in SD rats was established. The rats in the low,moderate and high dose groups were given 0.267 g/kg body weight,0.533 g/kg body weight and 1.600 g/kg body weight of cassia seed,red yeast rice,ginkgo biloba leaf and salvia miltiorrhiza compounds by gavage for 30 days. A blank control group and a model control group were also set. The levels of serum total cholesterol（TC）,triglyceride（TG）,high-density lipoprotein cholesterol（HDL-C）and low-density lipoprotein cholesterol（LDL-C）in the five groups were measured before and after the intragastric administration. Results : One week after the model was founded,the levels of serum TC,TG and LDL-C in the model control group were higher than those in the blank control group（P<0.05）. Before the intragastric administration,there were no significant differences in the levels of serum TC,TG,HDL-C and LDL-C between the model control group and each dosage group（P>0.05）. After the intragastric administration,there were no significant differences in the levels of serum HDL-C and LDL-C between the model control group and each dosage group（P>0.05）. The levels of serum TC and TG in the high dose group were significantly lower than those in the model control group（P<0.05）;There was no significant differences in the levels of serum TC and TG between the moderate dose,low dose group and the model control group（P>0.05）. Conclusion The compounds of cassia seed extract,red yeast rice,ginkgo biloba extract and salvia miltiorrhiza extract with a dosage of 1.600 g/kg body weight can reduce serum TC and TG levels in rats with hyperlipidemia.

Objective To propose a new three-dimensional method or grading scale in the evaluation of the secondary alveolar bone grafting,thus modifying the Bergland grading scale.Methods A total of 40 patients (26 male,14 female) with unilateral cleft lip and palate (UCLP),who underwent secondary alveolar bone grafting at least 3 months ago,were enrolled.Regional cone-beam CT(CBCT) scans were taken to evaluate the height and thickness of the postoperative bone bridges.A new three-dimensional grafting scale was established,including four grades respectively in alveolar height and thickness.Results According to the new three-dimensional scale in this study,15 grafted sites were rated grade T-Ⅰ or T-Ⅱ in the alveolar thickness among 18 sites of grade H-Ⅰ in height,and 10 among 15 of grade H-Ⅱ in height.Therefore,25 grafted sites were considered as clinical success in the alveolar thickness (grade T-Ⅰ or T-Ⅱ) among 33 sites with clinical success in alveolar height (grade H-Ⅰ and H-Ⅱ).There were 24％ of 33 sites with clinical success in height,which were considered as clinical failure in the alveolar thickness.Conclusions It is necessary to establish a new three-dimensional method or grading scale for evaluating the secondary alveolar bone grafting.The three-dimensional scale can take comprehensive view of the bone-grafted alveolar clefts and thus modify the Bergland grading scale.

[Objective]To analyze the pathogenesis and treatment of adolescent idiopathic scoliosis(AIS)in traditional Chinese medicine based on the theory of"five viscera deviation",and develop the idea of its diagnosis and treatment in traditional Chinese medicine.[Methods]By reviewing the ancient Chinese medicine literature related to AIS,and based on the theory of"five viscera deviation"in Huangdi Neijing,this research summarized the etiology,pathogenesis and therapeutic rules of Chinese medicine in AIS through the literature study,and explored the guiding role of Chinese medicine theory of"five viscera deviation"for the treatment and regimen of AIS.[Results]Literature research has found that the performance of the"five viscera deviation"in Huangdi Neijing is highly consistent with the lesion site and symptom characteristics of AIS.Based on the academic connotation of the theory of"five viscera deviation"in Chinese medicine,the etiology of AIS is based on endowment insufficiency,with dietary disorders and injuries caused by fatigue as the triggers,and the mechanism of the disease is based on the disorders of the spleen and kidney and the five viscera deviation,with the tendons out of the grooves and the bones out of joints as the symptoms,and the treatment should be based on the principle of adjusting the spleen and kidney,rectifying the five viscera,and emphasizing on both the tendons and the bones and the combination of internal and external treatments.The treatment should be a combination of internal medicine,external treatment,guiding and dietary therapy.[Conclusion]AIS is highly related to"five viscera deviation".Based on the theory of"five viscera deviation",it discusses the disease mechanism and treatment rules of AIS,which can provide Chinese medicine ideas for the clinical diagnosis and treatment of AIS,and worthy of attention,further exploration and clinical application.
