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.

Objective Base on the theory of traditional Chinese medicine (TCM), obtained human diagnostic information available for joint syndrome differentiation is integrated based on subjective and objective combined syndrome differentiation, in the form of data expression of TCM four diagnosis, forms multiple information fusion of open platform for TCM diagnosis and treatment, and provides some revelation for promoting the development of depression and treatment technology. Methods Totally 30 depression patients and 30 normal people were selected according to the inclusion criteria. TCM four diagnostic and auxiliary diagnosis instrument was used to collect information of four diagnosis, and the statistical software was used for the analysis on pulse diagnosis, and information features of digitalized tongue and listening diagnosis of patients in depression group and normal group were studied. Results Compared with depression group, pulse frequency, fluency, and heart rate of normal group were a bit higher than depression group, without statistical significance (P>0.05);There was statistical significance among pulse frequency, strength, tightness, and pulse wave velocity between the normal group and depression group (P<0.05). 30 patients had 6 depression syndrome types:heart-gallbladder qi deficiency (8 cases), phlegm-heat attacking internally (6 cases), fire excess from yin deficiency (6 cases), liver depression forming fire (6 cases), intense heart fire (3 cases), and heart-spleen deficiency (3 cases). Conclusion The results of differences in pulse diagram parameters were consistent with the theory of classical TCM pulse theory. The results of differences in pulse wave velocity conform to the modern medical research conclusion. TCM four diagnostic auxiliary diagnosis and treatment technology can realize the dynamic detection of depression patients with four diagnostic information, and establish diagnostic methods for depression based on digitalized four diagnostic auxiliary diagnosis.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.
