Nicotinic acid could increase high density lipoprotein and reduce serum total cholesterol, low density lipoprotein cholesterol and triglycerides in human bodies, thus is frequently applied in treating low high-density lipoprotein cholesterol and hypertriglyceridemia in clinic. However, according to the findings, nicotinic acid could also cause adverse effects, such as skin flush, beside its curative effects. In this study, bioisosterism, fragment-based search and Lipinski's Rule of Five were used to preliminarily screen out potential TCM ingredients that may have similar pharmacological effects with nicotinic acid from Traditional Chinese medicine database (TCMD). Afterwards, homology modeling and flexible docking were used to further screen out potential nicotinic acid receptor agonists. As a result, eleven candidate compounds were derived from eight commonly used traditional Chinese medicines. Specifically, all of the candidate compounds' interaction with nicotinic acid receptor was similar to nicotinic acid, and their docking scores were all higher than that of nicotinic acid, but their druggability remained to be further studied. Some of the eight source traditional Chinese medicines were used to lower lipid according to literature studies, implying that they may show effect through above means. In summary, this study provides basis and reference for extracting new nicotinic acid receptor agonists from traditional Chinese medicines and improving the medication status of hyperlipidemia.

Objective To establish the model for periventricular leukomalacia(PVL) by intracerebral injection of 3-nitropropionic acid (3-NPA) and explore realistic model for concerned studies and investigate the diagnostic method with magnetic resonance imaging (MRI) examination. MethodsSprague-Dawley rat pups of both sexes at the age of postnatal day 5 (P5) were randomized and divided into two groups: NPA group and PBS group , and they were injected the same volume of 3-NPA and PBS with a tip located at the corpus callosum above the left ventricle by stereotaxis instrument, respectively. One day (P6), two days (P7), three days (P8) and nine days (P14) after injection, the injections were transcardially perfused and brains were collected. Then sections of brains were undertaken HE staining; growth and the time of opening eyes of the rats in the two different groups were observed and compared. Neurobehaviorai activity and memory tests were performed on postnatal day 29 (P29) and day 30 (P30). MRI examination was performed on postnatal day 30 (P30). ResultsMore weight increase and slower opening eye time were found in the NPA group compared with PBS group (P < 0.05). In the NPA group, sub-cortical and periventricular white matter rarefaction were observed by HE staining on P6, P7 and P8, significant lateral ventricle enlargement was found on P14, while the same changes were not found in the PBS group, and no histological changes in gray matter were noted in both groups. The outcomes of neurobehavioral tests of NPA group were much more abnormal compared with the PBS group (P < 0.05). MRI examination disclosed the signal changes of brain tissue is worse in the NPA group than that of the PBS group in muscle strength of limbs, autocinesis, capability and white matter. ConclusionsThe model for PVL induced by intracerebral injection of 3-NPA is characterized by damage to the periventricular white matter. The model can stimulate the pathologic change factually in vivo. The neurobehavioral movement is consistent with.clinical symptom. It can be used as a model to investigate some related disease. MRI examination is a feasible diagnostic method to show anatomic changes of white matter injury of the brain.

Objective To explore the transport properties of the radionuclide strontium 90Sr in the soil-plant system,and discuss the accumulation characteristics of strontiumes in different vegetable tissues.Methods Three kinds of vegetables,including Chinese cabbage,radish and celery,were planted in this experiments using stable nuclide 88Sr instead of 90Sr.Strontium concentrations in these kinds of plant and soil were measured with inductively coupled plasma atomic emission spectrometry (ICP-AES),and the transportation factor (TF) of strontium and the concentration ratio (CR) of these plants were calculated.Results The contents of strontium in different tissues of the vegetables increased significantly in response to the strontium concentrations in soil (F =3.75-139.39,P ＜ 0.05).The contents of strontium at 398.33,477.99 and 557.57 mg/kg in different tissues of these vegetables were significantly higher than that in control group (t =-10.49-7.41,P ＜0.05).Except celery stems,there was a positive correlation about contents of the strontium between other tissues of these vegetables and their experimental soils (r =0.88-0.99,t =7.41-15.96,P ＜0.05).Based on dry weight of examples,the TF in each tissue sample of cabbage and radish was higher than 1,and the concentration ratio,for cabbage and radish,was higher in stems than in roots (F =8.22,91.49,P ＜ 0.05).Conclusions Three kinds of vegetables have been shown to have strontium accumulation ability in soil environment.

Objective To evaluate the safety and efficacy of radiofrequency catheter ablation(RFCA)in chil-dren with tachycardia arrhythmias. Methods One hundred and twenty - three children under 3 years old with drug -refractory tachycardia underwent an interventional electrophysiology procedure and RFCA in Medical Center of Tsinghua University from April 1994 to December 2014,including 98 male and 25 female,and their average age was(22. 9 ± 9. 6)months(2 - 35 months)and body weight was(13. 64 ± 2. 80)kg(4. 66 - 19. 40 kg). The mechanism,RFCA methods,the success rate,recurrence rate and complication rate of the different types of tachycardia were investigated. Results Among these children,interventional electrophysiological study confirmed 94 cases(76. 4% ,94 / 123 cases) with atrioventricular reentrant tachycardia(AVRT),7 cases(5. 7% ,7 / 123 cases)with atrioventricular nodal reentrant tachycardia(AVNRT),3 cases(2. 4% ,3 / 123 cases)with focal atrial tachycardia(FAT),8 cases(6. 5% ,8 / 123 ca-ses)with atrial flutter(AF),5 cases(4. 1% ,5 / 123 cases)with idiopathic left ventricular tachycardia(ILVT),6 ca-ses(4. 8% ,6 / 123 cases)arrhythmia was not induced. RFCA was performed in 109 cases(88. 6% ,109 / 123 cases). The success rate of RFCA was 94. 5%(103 / 109 cases)and the recurrence rate was 6. 8%(7 / 103 cases). In 88 cases of AVRT,the success rate was 96. 6%(85 / 88 cases),and the recurrence rate was 8. 2%(7 / 85 cases). In 5 cases of AVNRT,the success rate was 100. 0%(5 / 5 cases). In 3 cases of FAT,the success rate was 33. 3%(1 / 3 cases). In 8 cases of AF,the success rate was 87. 5%(7 / 8 cases). In 5 cases of ILVT,the success rate was 100. 0%(5 / 5 cases), and there was no recurrence. The complication of RFCA was puncture vascular occlusion in 2 cases(1. 6% ,2 / 123 ca-ses),without other serious complications and death cases. In this group of children,the fluoroscopy exposure time was (11. 2 ± 5. 8)min(5. 7 - 18. 2 min)and dose area product(DAP)exposure was(954. 5 ± 117. 4)mGy × cm2(707 -2 201 mGy × cm2 ). Compared with the elder children(379 cases over 3 years old)of the exposure fluoroscopy time (10. 8 ± 6. 4)min(3. 9 - 20. 5 min)and DAP exposure(927. 5 ± 193. 4)mGy × cm2(439 - 3 201 mGy × cm2 ),there was no statistically significant difference(t = 0. 616,1. 463,all P ﹥ 0. 05). Conclusions AVRT was the most common type of arrhythmia in infants and a higher incidence of multiple accessory pathways was found in infants. Application of radiofrequency ablation to children with tachycardia arrhythmias can be relatively safe and effective to the infants with drug - resistant tachycardia.
