Objective To investigate the protective effects of aerobic exercise and miR-222 expression in myocardium of diabetic mice. Methods C57BL/ 6 mice were divided into 4 groups: normal non-exercise group (SC), normal exercise group(EC), non-exercise diabetic group(SD), and exercise diabetic group(ED). After the diabetic model was established successfully, EC and ED underwent a swimming training for 5 weeks. By the end of the experiment, light microscope was used to observe the pathological changes of heart, RT-PCR for myocardial miR-222 expression, and Western blot for phosphatase and tensin homolog deleted on chromosome ten ( PTEN ), phosphatidylinositol 3-kinase (PI3K), and protein kinase B (Akt) protein expressions in myocardial tissue. Results (1) Under the light microscope, the diabetic mice had a significant change in myocardial structure, with great disorder in the cell arrangement. After exercise intervention, the lesion was alleviated. (2) MiR-222 expression was increased in the myocardium of normal mice and DM mice after exercise (all P<0. 05); (3) Compared with SC group, PTEN expression was increased and PI3K/ Akt expressions were inhibited in myocardium of diabetic mice(all P <0. 05). After exercise intervention, the expression of PTEN reduced( P < 0. 05) and PI3K/ Akt pathway was reactivated in myocardium of diabetic mice (all P<0. 05). Conclusion Exercise intervention may protect the myocardium under high glucose via inducing miR-222 and activating PI3K/ Akt signaling pathway.

Objective To study and compare the present situation and the difference in subjective well-being between students in junior high schools for the blind and normal junior high school students, and provide basis for the construction of education mode for the well-being of the blind students. Methods By random sampling method, subjective well-being questionnaire was used to investigate the 155 blind students in five blind schools and 436 normal junior high school students in three junior high schools in Shandong Province. Results ( 1 ) The blind students had shown significant differences in many aspects of subjective well-being such as gender, family e-conomic status, sight and parents'education degree (P<0. 05) . (2) Blind school students'social confidence experience (4. 59 ±1.13) was significantly higher than that of the normal students (4.31 ±1.13), and had a significant difference (P<0.05). Blind students got significantly lower scores ((4. 38 ± 1.26) , (4.00 ± 1. 29) ,(3. 58 ± 1. 37) ,(3.89 ± 1. 35) ,(4.41 ± 1.04) , (4. 20 ± 1. 33) ) than normal school students( (4.68 ± 1. 19) , (4. 36 ±1.14),(3.88±1.27),(4.41 ±1.25),(4.61 ±0.99), (4. 52 ± 1. 18)) in target value experience, physical health experience, mental health experience, interpersonal adaptability experience self-acceptance experience, and emotional balance experience. Conclusion There exists a significant difference between the blind students and the normal junior high school students in the different aspects of subjective well-being.

ObjectiveTo provide evidence for the education on sychological health for the undergraduates by analyzing the relationship among interpersonal relationship, coping style, self consistency and congruence of local college students. Methods uestionnaires about interpersonal relationship, coping style, and self consis tency and congruence have been carried out on a stratified random sample of 1471 students from four local colle ges. And all the data of the questionnaire scales will be dealt with by the software SPSS15.0. Results①Total scores on interpersonal relationship and self consistency and congruence of male college students( (9.88 ±5.51 );(93.29 ± 13.48 ) respectively) were much higher than the scores of the female college students ( ( 8.84 ± 5.11 );(90.09 ± 12.60) respectively). Total scores of the above two items for the seniors( ( 10.26 ± 5.89 ); ( 96.79 ±12.93) respectively) were obviously higher than the total scores of students of other grades. For the engineering students, whose total scores on the two items( ( 10.26 ±5.86); (93.57 ± 12.83 ) respectively) were remarkably higher than the scores of students of other majors. Regarding the various factors of coping style, there are signifi cant differences in gender, grade and major( P ＜ 0. 01 ). ②Concerning the college students, there were conspicu ous relationship among their interpersonal relationship, coping style, self consistency and congruence ( P ＜ 0.01 ). ③ Self consistency and congruence could be effectively predicted by factors, i.e. total score of interpersonai rela tionship, remorse, problem-solving, rationalizing, fantasy, recoil, help-seeking and grade. ConclusionCollege students' ability of self consistency and congruence is affected by their coping style and interpersonal relationship. To improve the individual' s ability of self consistency and congruence and the condition of their psychological health, the most effective way is to cultivate the capability on interpersonal communication and apply the positively flexible coping style.

Objective To study the therapeutic effect of pulse-activating injection on acute poisoning by pa-raquat(PQ). Methods 50 Sprague-Dawley (SD) rats were randomly divided into five experimental groups: blank group, negative control group, positive control group, low-dose pulse-activating injection group (LDG), and high-dose pulse-activating injection group(HDG) (n = 10 for each group). Blank group were injected with normal suline,30 ml/kg,and other groups were established as acute paraquat poisoning models. Macroscopic and histopathological ex-aminations were performed and biological indexes were measured for the lung specimens. The indexes included lung wet weight/dry weight,the rats of neutrophils and protein content in the pulmonary alveolar lavage fluid. In the mean time, the level of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) both in plasma and bronchoalveolar lavage flui(BALF) were detected. Results Compared with that in negative control group,lung congestion and lung edema of LDG group were mitigated; and the MDA level decreased from (5.04± 0.50) nmol/ml,(1. 19±0.18) nmol/ml to (4.04±0.21) nmol/ml,(0.79±0.04) nmol/ml both in plasma and BALF;the SOD activities were increased from (123.30±20. 39) U/ml, (26.43±2.22) U/ml to (277.09± 11.66) U/ml,(37.10± 2.49) U/ml as well; the GSH-Px activities were increased from (1796.63 ±81. 12) U/ml, (598.24 ± 62.50) U/ml to (2151.54 ± 148.32) U/ml, ( 1788.44 ± 175.11 ) U/ml as well ( P < 0. 01 ). Conclusions Administration of pulse-activating injection could improve the lipid peroxidation damage caused by a-cute poisoning of PQ.

Objective To explore the association of T cell immunoglobulin- and mucin-domain-containing molecule-3 (TIM-3) gene polymorphism and IFN-γ levels with the incidence of primary nephrotic syndrome (PNS) in children. Methods A case-control study was conducted and 21 Han patients with PNS were selected and included in case group. Meanwhile, 20 each from Mongolian and Han were selected and assigned into control group and at least three generations of their family members were from the same nationality. PCR-restriction fragment polymorphism analysis was used to detect and analyze single nucleotide polymorphisms of exon -574A/C in TIM-3 gene in PNS children and controls. Also the genotype and allele frequencies between the two groups were compared. Enzyme linked immunosorbent assay (ELISA) was used to detect the level of serum IFN-γ and its changes was analyzed. Results There was no significant difference in the distribution of genotypes (AA, AC, CC) of exon -574A/C in TIM-3 gene between the Han and Mongolian subgroups in control group (P=0.741). Neither did the allele frequency between the two groups (P=0.655). Compared with control group (Han and Mongolian), the frequencies of AA, AC and CC genotypes were 9.52%, 28.57% and 61.90% respectively in -574A/C loci of the Han nationality children with PNS. There was significant difference in genotypes distribution between the two groups (P=0.017). The frequency of C allele in PNS children of Han nationality was 76.2% which was higher than that in normal control group (50%), and the difference was statistically significant (P=0.005). Compared with A allele carriers, the risk of PNS in C allele carriers increased by 3.20 times (95%CI: 1.39～7.37). There were no significant differences in serum IFN-γ among the Han nationality with PNS, Han and Mongolian normal control groups (P>0.05). Conclusion The single nucleotide polymorphism of the exon -574A/C of TIM-3 gene may be related to the pathogenesis of PNS in children. In addition, IFN-γ is not associated with the incidence of primary nephrotic syndrome in children.

Objective:To evaluate the acute toxicity and protective effects of polysaccharide from Schisandrae sphenantherae Fruc-tus in the mice with acute liver injury induced by CCl4 . Methods:The classical acute toxicity tests were used to determine the maxi-mum drug loading (MLD) and observe the acute toxicity. The acute liver injury model was induced by 0. 5% CCl4. Sixty mice were randomly divided into the blank control group, CCl4 model group, bifendatatum model group and polysaccharide group respectively at high (1388 mg·kg-1), medium (694 mg·kg-1) and low (347 mg·kg-1) dose groups with 10 ones in each. After 6-day drug treatment, the levels of aspartate aminotransferase ( AST) and alanine aminotransferase ( ALT) were determined by kits. Histopatho-logical examination was also carried out. Results: General behavior, body weight and organ examination in the acute toxicity tests showed no obvious changes. Compared with those in the model group, the levels of AST in the three polysaccharide groups significantly decreased (P<0. 05 or P<0. 01), the levels of ALT in polysaccharide group at high and medium doses significantly decreased(P<0. 01), and the liver tissue damage was improved to a certain extent as well. Conclusion: Polysaccharide from Schisandrae sphenan-therae Fructus has protective effects on acute liver injury induced by CCl4 in mice with low acute toxicity.
