Objective To investigate the moderator of children' s perceptions quality of parental involvement on parenting style and children' s sport expectancy-value beliefs.Methods 595 students of grade 2 to 6 from five elementary schools were chosen and analyzed.Data were analyzed by SPSS16.0 software packet using independent sample t test,One-Way ANOVA,correlation analysis and hierarchical regression statistical analysis of regulation.Results Children' s expectancy beliefs was predicted by authoritarian and behavior encouragement(β=0.076,t =2.35,P=0.019 ;β =0.111,t =3.748,P =0.000).Children' s value beliefs was predicted by affect -warmed and behavior encouragement (β =0.070,t =2.883,P =0.004 ;β =0.070,t =2.745,P =0.006).Children' s sport behavior was predicted by trust-encouragement(β=0.294,t=3.193,P=0.001).The prediction of expectancy beliefs was significant positive by the interaction between indulgence and time involvement (β=0.078,t =2.065,P =0.039).The prediction of expectancy beliefs was significant negative by the interaction between authoritarian and time involvement(β=-0.084,t =-2.454,P=0.014).The prediction of expectancy beliefs was borderline significant positive by the interaction between neglecting and equipment provision(β=0.073,t =1.94,P =0.053).Conclusion Different parenting styles are significant predicators of children sport involvement.Children' s perceptions quality of parental involvement play an important role on parenting style and children' s sport expectancy-value beliefs.

In critically ill patients,evoked potential(EP) testing is an important tool for measuring neurologic function,signal transmission,and secondary processing of sensory information in real time.EP potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing.In critically ill patients with limited neurologic exams,EP provides a window into brain function and the potential for recovery of consciousness.Brainstem auditory EP and cortical event-related potentials are most commonly used in ICU.The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma,monitoring for neurologic improvement or decline,and confirmation of brain death.Historically,EP has been regarded as a negative prognostic test,that is,the absence of cortical potentials are associated with poor outcomes while the presence cortical potentials are prognostically indeterminate.In recent studies,the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes.Event-related potentials,particularly mismatch negativity of complex auditory patterns,is emerging as an important positive prognostic test in patients under comatose.In infants,other than anoxic-ischemic or traumatic brain injury,brainstem auditory is also widely used in premature baby,bilirubin encephalopathy and detection of possible hearing loss.

Natural biocompatible nanomaterials such as self-assembled triterpene natural small molecule products with favorable anticancer activity show great potential for biomedical application. However, the mechanisms of their molecular self-assembled structures have not been investigated systematically, while there are still few reports of the natural active carrier for drug delivery. Herein, in this work, we further explored the molecular assembly mechanism and common regularity of tetracyclic triterpenes ergosterol, stigmasterol as well as pentacyclic triterpenes glycyrrhetinic acid and ursolic acid, which suggested that the coplanarity and orderliness of molecular arrangements which are speculated to be responsible for their self-assembly into the spherical, rod-like or lamellar nanostructure. Besides, ergosterol (ET) with better anticancer activity was chosen as a representative substance for construction of the synergistic antitumor nanodrug. By intermolecular hydrogen bonding and π-π stacking, chemotherapeutic drug paclitaxel (PTX) was encapsulated into ET-PTX NPs successfully. Then, the anti-cancer efficacy of the tumor-bearing mice was evaluated according to the protocol approved by the Experimental Animal Research Center of Harbin Medical University. The resulting nanodrug exhibited excellent biosafety and enhanced in vivo anticancer activity efficiency of 52.3%, higher than free PTX (29.4%) or ET NPs (32.5%) alone, further verifying the potential medical application value of triterpene natural products. This work provides not only a theoretical basis for exploring the self-assembly behavior of small molecule natural products, but also a promising perspective for the fabrication of active natural biocompatible nanodrug delivery systems for synergistic antitumor therapy and other biomedical applications.

Corydalis Rhizoma, the dried tuber of Corydalis yanhusuo (Papaveraceae) distributed traditionally mainly in south-eastern and now cultivated in northwestern and other district in China, is one of the commonly used and well-known traditional Chinese medicine. It has been widely used to treat spastic pain, abdominal pain, pain due to injury, and promote blood circulation. Its main chemical constituents were alkaloids, which were divided into the two types of protoberberines and aporphines. Among them, some alkaloids were found to elicit profound effects on the dopaminergic system in the central nervous system, which plays an important role in regulating nociception. In this article, the chemical composition and structure-types, new methods of qualitative and quantitative analysis as well as characteristics of biotransformation, absorption, distribution, metabolism, excretion, pharmacokinetic, and drug-drug interaction for the alkaloids were revealed. These results would greatly contribute to the establishment of bioactive material base of Corydalis Rhizoma.
