Objectives To explore the change of interleukin-17 (IL-17) in Kawasaki disease (KD). Methods Fourty KD pediatric patients, among them 12 patients with echocardiographic abnormalities in acute phase, 25 age-matched non-KD patients were enrolled. The level of serum IL-17 was measured by enzyme linked immunosorbent assay in acute and convalescent phase of KD patients and non-KD patients. At the same time, C-reactive protein (CRP), globulin, albumin were detected. Results In acute phase of KD patients, the level of serum IL-17 were signiifcantly higher than that in convalescent phase of KD patients and non-KD patients (P<0.05). The level of serum IL-17 was no signiifcant differences in convalescent phase of KD patients and non-KD patients (P>0.05). In acute phase of KD patients with echocardiography abnormalities, the level of serum IL-17 was signiifcantly higher than that with non-echocardiography abnormalities (P<0.05). The level of serum IL-17 in acute phase of KD patients were positively correlated with CRP and globulin (r=0.750, 0.750, P<0.05), and negatively correlated with albumin (r=-0.779, P<0.05). Conclusions IL-17 may be involved in KD immune pathogenesis. Serum IL-17 is one of the activity index of KD, which associ-ated with cardiovascular damages.

Objective To further investigate the threshold value and the dose-effect relationship of infrasound on the rat pallium, and to observe the effects on the pallium's ultrastructure. Methods Rats were exposed to 16 Hz, 90 dB infrasound for 2 hours daily. With a transmission electron microscope, changes in the ultrastructure of the cortex of the rats' parietal lobes were observed 2 hours, 3 days and 7 days after the treatment. Results There were no changes in the ultrastructure of the pallium in rats which had been exposed for 7 days or 14 days. Denaturation appeared when the rats had been exposed for 21 days, 28 days or 35 days. Denaturation become more serious as the exposure time increased beyond 21 days. Denaturation and damage gradually returned to normal with time after exposure. Conclusion 16 Hz, 90 dB infrasound exposure over an extended time may cause denaturation and other changes in the ultrastructure of the pallium in rats. Such changes can return to normal with time.

Objective To appraise the clinical value of velocity vector imaging(VVI) by analyzing the peak systolic velocities,strain and strain rate of ventricular segments in patients with DDD pacing. Methods eventeen patients with DDD pacing were enrolled in this study. The peak systolic velocities, strain andstrain rate of ventricular segments were measured with VVI. The difference at baseline and after pacemaker implantation was analyzed. Results Left and right ventricular (LV and RV) longitudinal peak velocities at baseline and after DDD pacing were significantly decreasing from basal, mid to apical segments. But no significant difference was found in longitudinal strain,strain rate and radial motion characteristic of LV. The mean systolic velocities and strain rate at baseline and after pacemaker implantation and strain with pacing of RV posterior septum and free wall were higher than those of posterior septum and lateral segment of LV respectively. The mean strain and strain rate of RV after pacing were higher than that of LV. Compared with the values at baseline, mean strain of LV with pacing was lower significantly. Conclusions VVI can accurately assess ventricular systolic function in patients with DDD pacing, and can become a powerful means in assessing the regional myocardial function.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.
