BACKGROUND: Dance-sport is a newly emerging sport item, integrating sport with music and dance. It not only develops physical diathesis and sport skills, but also actively affects psychological health of university students.OBJECTIVE: To analyze and observe the changes in psychological health, physical diathesis and musical cultivation after dance-sport training for university students.DESIGN: Cross-section investigation was designed, in which, the students in elective class of dance-sport were taken as objects.SETTING: Department of Physical Education of China University of Mining and Technology.PARTICIPANTS: Totally 116 students were collected from 2001' elective class of dance-sport in China University of Mining and Technology from September 2001 to January 2003. All of receptors selected dance-sport at the first time. Of 120 copies of Symptom Checklist 90 (SCL-90) were provided and 116 of those were returned, in which, 58 students were either male or female, aged averagely 19.7 years.METHODS: Questionnaire: SCL-90 was used to evaluate 9 main outcome measures, named psychological health, somatization, obsessive compulsive (o-c) symptoms, personal relations, depression, anxiety, hostility, phobism,paranoid ideation and metal disorder; in which, 5 grades were adopted,named 1, 2, 3, 4 and 5 grades, to represent no, mild, moderate, severe and extremely severe impacts successively. Test: according to stipulated music rate, cardiac rate and music were tested so as to observe the changes in physical diathesis and capacity of musical rhythm understanding. Simultaneously, literatures were looked up on education, psychology and physical education to provide theoretic evidence for this paper. The questionnaire was provided before and after the semester respectively and returned for music test. Test on cardiac rate was performed at the end of semester.MAIN OUTCOME MEASURES: Comparison among the results of two SCL-90 evaluations, positive number and total average result in receptors and national norm. Result of cardiac rate and music test in receptors.RESULTS: Totally 120 copies were provided, 116 of them were returned and the rate of return was 97%. ① Result of SCL-90: At the end of semester, the results of depression, hostility and positive number of 9 items in the checklist were lower remarkably than those before the semester (P ＜ 0.01-0.05); the results of somatization, interpersonal sensitivity, depression, hostility and total average result were lower remarkably than national norm (P ＜ 0.01-0.05). ② Dance-sport and physical diathesis:Among various dances in sport, the highest, lowest and average cardiac rates were (115-194) times/minute, (114-140) times/minute and (138-169) times/minute successively. The amount of exercise is over moderate level and it benefits cardiac vascular system, functions of heart and lung,endurance, etc. Long-term exercise will be good for the physique. ③ Impacts of dance-sport on music cultivation: Before the class, 93.1% of students did not understand musical rhythm or they understood the rhythm,but it is hard for their steps followed the rhythm. After the course of dance-sport, only 2.5% of students did not understand and follow musical rhythm.CONCLUSION: Dance-sports improves not only psychological health and physical diathesis of students, but also their musical and art cultivation.It is mass sports activity, benefiting the health both physically and mentally.

Objective: To survey changes and the significance of phospholipase A 2 (PLA2) on brain tissue of SD rat in acute pancreatitis. Methods: With retrograde injection of 3% taurocholate sodium into pancreatic and biliary duct, rat model of severe acute pancreatitis (SAP) was made, and it included four groups; the control group, the sham-operation group, the SAP group and the PLA2 inhibitor-treated group of SAP. Serum amylases, PLA2 and PLA2 in brain tissue were measured and the brain tissue changes were observed. Results: There were no significant difference in serum amylases, PLA2 and PLA2 in brain tissue between the sham-operation and the control groups; the levels of serum amylases, PLA 2 and PLA2 in brain tissue in the SAP group were higher than those in the control. In the SAP group expansion and hemorrhage of meninges, intracephalic arteriolar hyperemia, in meninges and cephalic-parenchyma infiltration of inflammatory cells and interval broaden were observed, significant differences were found between two groups. Compared with the SAP group, the level of serum amylase, PLA2 and PLA2 in brain tissue were reduced significantly in the treatment group of SAP. Pathological damages in the treatment group were significantly reduced when compared with the SAP group. Conclusion: PLA2 might play an important role in brain tissue damages in severe acute pancreatitis.

RNA-seq can help us quickly obtain the whole transcriptome sequences of species under different conditions. Many Unigenes that are assembled by raw reads always do not contain complete open reading frame (ORF). In addition, it also has some redundancy in transcriptome library. Some Unigenes in the library, although belong to one transcript, cannot be assembled without overlapping. We found five incomplete Unigenes annotated ammonium transporter (AMT) from Salicornia europaea transcriptome, in which two Unigenes (Uni4 and Uni5) had identical expression patterns across four transcriptomes. The two Unigenes may come from one transcript. Analyzing the Unigene position of transcript by NCBI blastx, we found that Uni4 and Uni5 respectively located in 5' end and 3' end compared with the reference transcript, and an unknown gap of 120 bp may exist in a hypothetic transcript to which Uni4 and Uni5 both belong. To verify the hypothesis, single forward primer and single reverse primers were respectively designed on Uni4 and Uni5, and a fragment with about 800 bp was generated by PCR. Then it was sequenced and aligned with Uni4 and Uni5. Finally, we assembled a sequence with 1 667 bp, which contains a complete ORF (1 482 bp, coding 494 amino acids). It belongs to amt1 subfamily and was named Seamt1 via the phylogenetic analysis. It was pointed by bioinformatics tools that SeAMT1 protein conformed to the AMT characteristics of other species. This work clustered expression pattern to explore the Unigenes of one transcript, and the feasibility of this method was validated through the other two groups of Unigenes. The handy method will benefit extension and assembling of Unigene in transcriptome, it also helps achieve the complete ORF and gene function.

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.

BACKGROUND: Recently,liver transplantation technique has been developed rapidly,and prevention of ischemia/reperfusion injury and protection of liver regeneration have become a research focus.Ischemic preconditioning(IPC)is an effective method for protecting liver ischemic injury.However,the mechanism remains controversial.OBJECTIVE: To investigate the mechanism of IPC on hepatic injury and regeneration after reduced-size rat liver transplantation.METHODS: Animals were randomly divided into 3 groups.Rat reduced-size liver transplantation model was established in liver transplantation group.IPC+liver transplantation group underwent first porta hepatis blocking for 10 minutes before liver graft reperfusion,followed by reperfusion for 15 minutes.The ligament around the liver was dissociated in the sham-surgery group.The samples were collected 0.5,2,6 and 24 hours post-operation.The hepatic injury was examined by the serum alanine aminotransferase(ALT)and hepatic tissue histopathology analysis of grafts.Semi-quantitative immunohistochemistry and westernblotting were used to examine the redox factor-1(Ref-1)protein expression.The hepatic regeneration of the grafts was examined by the expression of proliferating cell nuclear antigen(PCNA)in hepatic cells.RESULTS AND CONCLUSION: Compared with liver transplantation group,the ALT values at 6 and 24 hours after operation in IPC group decreased significantly(P < 0.05; P < 0.01).Pathological analysis indicated that there were lots of inflammation cells around the portal veins,the serious sinus hepaticus dilation and damage of hepatic tissue in liver transplantation group.However,the tissue injury observed in IPC group was comparatively slight.Semi-quantitative immunohistochemistry revealed that Ref-1 protein was more abundant in IPC grafts tissue compared to liver transplantation group.These observations were supported by westernblotting studies where Ref-1 protein was shown to be over-expressed in IPC specimens at 24 hours after reduced-size liver transplantation(P < 0.05).In addition,the number of PCNA-positive cells in IPC group was more than liver transplantation group at 2,6 and 24 hours after operation(P < 0.05).IPC improves hepatic regeneration and relieves grafts injury in earlier period after reduced-size rat liver transplantation,which is associated with the over-expression of Ref-1protein.
