Aim To investigate the sedative and hyp-notic effects of a novel compound H057 . Methods The sedative activity of H057 was investigated by re-cording the spontaneous locomotor activity in mice. The hypnotic property was evaluated by the latency and duration of loss of righting reflex( LORR) in mice and effect of H057 on the sleep onset in subthreshold dos-age of sodium pentobarbital treated mice. The extracel-lular levels of GABA and monoamine neurotransmitters in in cerebral cortex were measured by microdialysis in vivo. Results The spontaneous locomotor activity was decreased by 25% and 66% in H057 ( 5 , 25 mg · kg-1 ,i. p. ) treated mice, respectively. H057 ( 3, 5 mg·kg-1 ,i. p. ) increased the sleep onset to 62. 5%and 87. 5% in subthreshold dosage of sodium pentobar-bital(25 mg·kg-1,i. p. ) treated mice. H057(≥60 mg· kg-1 , i. p. ) could completely induce LORR in mice. The latency of LORR at dose of 60 mg · kg-1 was (24 ± 11) min and the duration of LORR was (96 ± 15 ) min. In vivo mircodialysis revealed that H057 (25 mg·kg-1 , i. p. ) could significantly increase the GABA level by 26% and decrease the 5-HT and NE levels by 50% and 38% in cerebral cortex in mice. Conclusion H057 has potent sedative and hypnotic effects, which may be closely related to the increased content of GABA and the decreased contents of 5-HT and NE in the extracellular fluid in cerebral cortex.

Orthostatic hypertension (OHT) is a common type of syncope in children, characterized by a highly complex neural reflex mechanism.It is closely associated with abnormalities in vascular endothelial function, disruptions in the renin-angiotensin-aldosterone system, and reduced or deficient levels of vitamin D. However, the exact pathogenesis of OHT remains unclear.OHT has a relatively high incidence and may be a risk factor for hypertension and cardiovascular diseases in children, significantly impacting their physical and mental health.Nevertheless, the etiology and treatment of OHT are still in the exploratory stage.Therefore, a thorough exploration of OHT is essential.This review provided a brief overview of the pathogenesis and clinical diagnosis and treatment of OHT.

Orthostatic intolerance (OI) is the most common type of autonomic mediated syncope in children.Children with OI tend to show intolerance to the postural changes and long-term standing, thus often presenting with such clinical symptoms as dizziness, headache, blackness, and even sudden fainting.Although there is no organic lesion from OI, it can still exert serious impacts on the mental health of children.Therefore, it is of great significance to provide active and effective treatment for children with OI.There is some understanding of OI, but it is still unclear about its pathogenesis, which is believed to be related to dysautonomia and abnormal neurohumoral regulation.In this paper, the focus would be placed on the changes of renin-angiotensin-aldosterone system (RAAS) in neurohumoral regulation and their significance, and an exploration would be performed on the impacts of related treatment on RAAS in children with OI.

Objective To summarizes the experiences and technique of complex transradial percutaneous coronary intervention (PCI) using sheathless guide catheter (Sheathless Eaucath, ASAHI) for 60 patients with coronary heart disease. Methods Retrospectively analyzed the data from 60 patients received PCI using sheathless guide catheter. Results PCI were performed on a total of 60 patients with complex lesions. Angiographic success was achieved in 95.0%and failed in three patients with CTO. 7 patients were with left main lesions, and 32 patients were with bifurcation lesions(including 7 patients with left main lesions and 2 patients with CTO), and 13 patients were with CTO, and the other 17 patients were with tortuous and calcified lesions. Sheathless guide catheters of 7.5Fr were used for PCI in all patients, and all catheters successfully passed through the radial artery and were put in place. No other vascular complications associated with the use of the catheter occurred. Sheathless guide catheters were respectively JL(8 patients), PB(2 patients), AL(2 patients), and JR(1 patient) in 13 patients with CTO, and were respectively JL(8 patients), JR(6 patients), SPB(2 patients), AL(1 patient) in 17 patients with tortuous and calcified lesions. JL or JR were used in all 32 patients with bifurcation. Conclusions Use of the Sheathless of 7.5 Fr is safe and feasible, and allows complex interventions to be undertaken transradially with a high success rate.

Conclusions Use of 4F catheter with Mother-Child method is safe and effective for patients where stent delivery is difficult by the conventional method.

Objective To ascertain the specific activities of nigericin on inhibiting human epithelial ovarian cancer(EOC)cells,and to investigate the possible molecular mechanism of nigericin on cell migration and invasion.Methods Cell viability under different treatments of nigericin(0.312 5,0.625,1.25,2.5,5,10,20,40,80 μmol/L)on EOC A2780 and SKOV3 cell lines was examined by CCK-8 assay,with DMSO as a control.The human epithelial ovarian cancer cell lines A2780 and SKOV3 were treated with 5,10 or 20 μmol/L nigericin or with DMSO as a control.Transwell chambers was used to observe the impact of nigericin on migration and invasion of EOC cells.Western blot was used to detect the expressions of epithelial cell marker(E-cadherin),mesenchymal cell marker(Vimentin)and the epithelial-mesenchymal transition(EMT)-related transcription factors Slug,Snail,and Twist,as well as the expressions of proteins related to Wnt/β-catenin signaling pathway such as Gsk-3β,p-Gsk-3β and β-catenin under different concentration treatment of nigericin.Results CCK-8 assay showed that nigericin exhibited strong cytotoxicity on A2780 [ IC 50(16.19 ± 0.26)μmol/L,95％CI 1.077-1.341)] and SKOV3 [ IC50(11.87 ±0.21)μmol/L,95％CI 1.003-1.146] cell lines.Transwell chamber assay revealed that nigericin at different concentration(5,10,20 μmol/L)induced a remarkable reduction in the number of cells migrating through the membrane relative to the vehicle-treated controls in A2780 and SKOV3 cells [(121±9),(92±7),(59±5)/HP and(120.4±2.6),(91.8±5.5),(80.0±4.0)/HP,all P <0.05]; the invasive ability of A2780 and SKOV3 cells also inhibited [(61.2±3.7),(43.2±4.3),(23.6±2.1)/HP and(85.2±7.0),(65.2±4.6),(45.6±4.4)/HP,all P< 0.05].Western blot revealed that the increased expression of E-cadherin and decreased expression of Vimentin,Slug,Snail,Twist,p-Gsk-3β,β-catenin in EOC cells with the nigericin treatment at different concentration(5,10 and 20 μmol/L)showed concentration dependence(P < 0.05).Conclusion Nigericin may induce EMT by activating Wnt-β-catenin signaling pathway to promote the migration and invasion of EOC cells.

Cytoplasmic processing bodies, termed P bodies, are involved in diverse post-transcriptional processes including mRNA decay, nonsense-mediated RNA decay (NMD), RNAi, miRNA-mediated translational repression and storage of translationally silenced mRNAs. Regulation of the formation of P bodies in the context of multicellular organisms is poorly understood. Here we describe a systematic RNAi screen in C. elegans that identified 224 genes with diverse cellular functions whose inactivations result in a dramatic increase in the number of P bodies. 83 of these genes form a complex functional interaction network regulating NMD. We demonstrate that NMD interfaces with many cellular processes including translation, ubiquitin-mediated protein degradation, intracellular trafficking and cytoskeleton structure.We also uncover an extensive link between translation and RNAi, with different steps in protein synthesis appearing to have distinct effects on RNAi efficiency. Moreover, the intracellular vesicular trafficking network plays an important role in the regulation of RNAi. A subset of genes enhancing P body formation also regulate the formation of stress granules in C. elegans. Our study offers insights into the cellular mechanisms that regulate the formation of P bodies and also provides a framework for system-level understanding of NMD and RNAi in the context of the development of multicellular organisms.

Objective To evaluate the relationship between concurrent myocardial bridge at anterior descending branch and the formation of coronary atherosclerosis plaques by using transluminal attenuation gradient (TAG). Methods A total of 198 patients underwent coronary CTA in Renji Hospital of Shanghai Jiaotong University School of Medcine from June 2017 to March 2018 and the results showed the anterior descending myocardial bridge. The data were retrospectively analyzed. All patients completed the coronary CTA with 320?row detector CT. According to the manifestations of myocardial bridge on CTA,the patients were divided into deep and superficial myocardial bridge groups. According to whether the patients were complicated with coronary atherosclerotic plaques, they were divided into isolated myocardial bridge group and myocardial bridge with coronary atherosclerotic plaque group. The thickness and length of myocardial bridge, the volume of coronary atherosclerotic plaques at the site of myocardial bridge, the pre?bridge and post?bridge TAG values, and the K ratio were recorded. Independent sample t test (normal distribution) or Mann?Whitney U test (skewed distribution) was used to compare the difference of measurement data among different groups. χ2 test was used to compare the difference of enumeration data among different groups. Pearson correlation test was used to analyze the correlation among pre?bridge and post?bridge TAG values,K ratio,thickness and length of myocardial bridge and plaque volume. The influence of above indexes on plaque occurrence was analyzed by binary logistic regression analysis. The relationship between main influence indexes and plaque formation was analyzed by receiver operating characteristic curve (ROC). Results Ninety nine patients had isolated myocardial bridge,99 with myocardial bridge and coronary atherosclerotic plaques,27 with superficial myocardial bridge and 171 with deep myocardial bridge. All atherosclerotic plaques occurred in pre?bridge and the mean volume of plaques was (91.6±83.0)mm3. The differences in sex, age, height, body weight and body mass index werenot statistically significant between isolated myocardial bridge group and myocardial bridge with coronary atherosclerotic plaque group (all P>0.05). The difference in pre?bridge TAG value was statistically significant between the isolated myocardial bridge group and myocardial bridge with coronary atherosclerotic plaque group (all P<0.05), but not statistically significant in post?bridge TAG value and K ratio (all P>0.05). The difference in pre?bridge and post?bridge TAG values and K value was not statistically significant between the superficial group and the deep group (all P>0.05). There was a weak negative correlation (r=-0.205,-0.316,-0.339,respectively,P<0.05) between the plaque volume and pre?bridge&post?bridge TAG values and K ratio. The pre?bridge TAG value significantly affected the plaque formation (P=0.014) and the odds ratio was 0.884 (95% CI 0.801 to 0.976). While other factors had no significant effects on plaque formation (all P>0.05). The area under curveof plaque formation promoted by pre?bridge TAG value was 0.582. When the diagnostic critical value was －37.26 HU/mm, the sensitivity and specificity of pre?bridge TAG value in plaque formation were 31.31% and 81.82%, respectively. Conclusion The TAG value of anterior descending bridge is an independent risk factor for plaque occurrence. The abnormal TAG value of anterior descending myocardial bridge can be detected early by CTA.
