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.

BACKGROUND:Coracoclavicular ligament reconstruction with transclavicular-transcoracoid driling is an effective surgical technique to treat acromioclavicular dislocation. A good driling in the clavicle leads to a perfect bony tunnel and a good surgery. OBJECTIVE: To observe the effects of different driling positions of the clavicle on the location of bony tunnels in coracoclavicular ligament reconstruction. METHODS:Sixty three-dimensional digital models of the clavicle and coracoid process were constructed by Mimics13.0. Virtual transclavicular-transcoracoid bony tunnels were established according to different surgical planes with different driling positions in the clavicle. Parameters of these bony tunnels were measured, and the safety was evaluated. Option 1: The driling was made 30 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 2: The driling was made 40 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 3: The driling was made at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process, located at the rear edge of the clavicle upper surface. RESULTS AND CONCLUSION: Bony tunnels in option 1 were extremely on the inside of the coracoid. Bony tunnels in options 1 and 2 were not in the center of clavicle. Bony tunnels in option 3 were in the center of both clavicle and coracoid. The method of locating the driling position with a certain distance to the distal clavicle leads to different results in man’s and woman’s models. To ensure that the bony tunnel can pass through the center of clavicle and coracoid, it is suggested to dril at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process and nearby the rear edge of the clavicle upper surface.

Objective To investigate the effects of exogenous hydrogen sulfide on brain edema and injury and their mechanisms. Methods Sixty male SD rats were randomly divided into a sham operation group, an ischemia-reperfusion group, a 30 ppm hydrogen sulfide group, and a 60 ppm hydrogen sulfide group (n =15 in each group; 1 ppm =1 mg/L). A model of focal cerebral ischemia for 2 h and reperfusion for 24 h was induced by middle cerebral artery occlusion. The neurological scores were observed after 24 h cerebral ischemia-reperfusion. The cerebral infarction volume, the degree of brain edema, and the changes of blood-brain barrier permeability were measured. Western blotting was used to detect the expressions of occludin and zonula occludens-1 protein (ZO-1) in ischemic penumbra. Results Compared with the ischemia-reperfusion group, the neurological function scores in the 30 ppm and 60 ppm hydrogen sulfide group significantly increased in a dose-dependent manner (al P <0.05) and the neurological deficits and infarct volume reduced (al P < 0.05), and the
brain edema aleviated (al P < 0.05). The content of Evans blue in the ischemic brain tissue in the ischemia-reperfusion group increased significantly compare with the sham operation group (0.74 ±0.14 μg/100 mg vs. 0.19 ±0.06 μg/100 mg; P <0.05). The content of Evans blue in the brain tissue in the 30 ppm hydrogen sulfide group (0.55 ±0.10 μg/100 mg ) and the 60 ppm hydrogen sulfide group (0.35 ±0.08 μg/100 mg ) decreased significantly compared with the ischemia-reperfusion group (al P < 0.05), among them the 60 ppm hydrogen sulfide group was significantly lower than the 30 ppm hydrogen sulfide group (P <0.05). Western blot analysis showed that expression levels of occludin in penumbra (0.621% ±0.101% vs.0.787% ±0.087% vs.0.453% ± 0.127%; P <0.05) and ZO-1 (0.602% ±0.118% vs.0.778% ±0.805% vs.0.426% ±0.146; P <0.05) in the 30 ppm and 60 ppm hydrogen sulfide groups increased significantly compared with the ischemia-reperfusion group, among them, the expression levels of occludin and ZO-1 in the 60 ppm hydrogen sulfide group were significantly higher than those in the 30 ppm hydrogen sulfide group (al P < 0.05). Conclusions Inhalation of exogenous hydrogen sulfide can significantly attenuate brain edema after ischemia-reperfusion in a dose dependent manner, reduce infarct volume, and improve neurological function.Their mechanisms may be associated with inhibiting the downregulated expressions of occludin and ZO-1 and maintaining the integrity of the blood-brain barrier.

Objective To analyze distribution of intracranial and extracranial arteriostenosis in patients with ischemic stroke. Methods 306 patients with ischemic stroke were collected during January 2002 to March 2005. All patients underwent color ultrasonography of carotid, TCD, MRA and DSA. According to NASCET, arteriostenosis was grouped into five grades: normal artery, mild stenosis(29%), moderate stenosis (30%—69%), severe stenosis(70%—90%) and occlusion(100%). Results (1) As for incidence of intracranial and extracranial arteriostenosis, 149 were of intracranial stenosis, 25 extracranial stenosis and 33 both. (2) As for incidence of single or dual stenosis, among 207 with arteriostenosis, single stenosis amounted to 129 and dual to 78. (3) Stenosis occurred in middle cerebral artery, distal vertebral artery, basilar artery, extracranial part of internal carotid artery, anterior cerebral artery, posterior cerebral artery, siphon part of internal carotid artery and onset part of vertebral artery in an order of decreased frequency. (4) DSA analysis revealed that, among 316 narrow blood vessels of 207 patients, 87 vessels were shown as severe stenosis or obstruction, accounting for 27.5%. (5) Among 164 cases, infarction occured in the corresponding stenostic vessel in 157 patients, accounting for 95.7%. ConclusionsIntracranial arteriostenosis is the most frequently encountered in those with ischemic stroke. Thereto, frequency of stenosis in middle cerebral artery is the highest, distal vertebral artery and basilar artery are next.

Objective To explore the association of serum uric acid level with non-alcoholic fatty liver disease(NAFLD) in Han and Uyghur ethnic groups.Methods A cross-sectional study was performed in the population in 2011 in the First Affiliated Hospital of Xinjiang Medical University.The study included 2439 Uyghurs and 2285 Hans with a questionnaire survey,and body mass index (BMI),waist circumference,blood pressure,blood glucose,blood lipid,and serum uric acid (SUA) level were measured.The participants were divided into 4 groups according to the quartiles of the SUA levels within the normal range,and those with SUA levels above the normal range served as hyperuricemia group.The associations between serum uric acid level and prevalence of non-alcoholic fatty liver,hyperuricemia,and metabolic syndrome (MS,including each component of MS) were analyzed.Results Among Uyghurs and Hans,the detection rates of NAFLD were 26.7％ and 23.6％ respectively,the detection rates of hyperuricemia were 7.8％ and 18.2％,and the level of serum uric acid in Uyghur group was lower than that in Han group (P＜0.01).The detection rate of NAFLD in the hyperuricemia patients was significantly higher than that in nonhyperuricemia group.Among the Uyghurs and Hans,the detection rates of NAFLD in the hyperuricenia patients were 24.0％ and 19.9％.The detection rate of NAFLD was positively associated with concentration of serum acid even that within the normal range.Conclusion The relationship between the level of serum uric acid and the prevalence of NAFLD is more evident in Uyghur than that in Han.

Objective To investigate the influence of early hyperbaric oxygen (HBO) therapy on cerebral edema and neural function in patients after minimally invasive surgery for intracerebral hemorrhage (ICH).Methods A random number table was used to divide 148 ICH surgery patients into a control group (n =75) and a treatment group (n =73).In the treatment group,HBO was administered in 51 cases 6-24 hours after surgery and then once a day for twenty days.Cerebral edema volume was measured by brain CT before the operation and on the 3rd,7th,14th and 21st day after the surgery.Neurological impairment was scored at the same time points.Results Average cerebral edema volume was significantly smaller in the treatment group than in the control group on the 7th,14th and 21st days,but not on the 3rd day.The neurological impairment scores (NIS) after therapy were significantly lower than that before therapy in both groups.The two groups' average scores were not significantly different before the operation or on the 3rd day,but they were significantly lower in the treatment group thereafter.Conclusion Early HBO therapy can significantly reduce cerebral edema and contribute to nerve functional recovery in patients after minimally invasive ICH surgery.
