Objective To explore conduct disorder tendency and it's influence factors on secondary school students. Methods 669 students of grade 1 in Dezhou Vocational and Technical College were investigated by Conduct Disorder Tendency Questionnaire, Revised Version of MBI-SS and SRHMS Version1.0. Results The secondary vocational school students' scores on violation tendency, addiction tendency and aggression tendency were 11.51±4.08,5.90±2.68 and 6.68±2.63,and were significant different from vocational college students or high school students(addiction tendency:F(2, 1578)=7.48,P =0.001;aggression tendency:F(2, 1579)=24.40,P <0.001). There existed great capable difference of conduct disorder according to genders ( t(643)>3.85,P <0.001).Conduct disorder tendency of secondary vocational students' was positive correlated with their learning burnout (Pearson correlation coefficient was between 0.16 and 0.52 for each pair), but negative correlated with mental health(Pearson correlation coefficient was between -0.13 and -0.27 for each pair). The linear regression showed that some dimensions of learning burnout and self-rated mental health predicted students' conduct disorder tendency. Conclusion Conduct disorder tendency of secondary vocational students is affected by their learning burnout and mental health.

Objective: To study the mechanism of Tuina in the treatment of skeletal muscle injury. Methods: Rabbits were heavily beaten at gastrocnemius muscle to make acute contusion model and then treated respectively by early Tuina and routine Tuina. The number of satellite cells of skeletal muscles was observed. Results: The number of the satellite cells continued to grow in both groups, and it began to increase significantly 3-5 days after Tuina treatment. Early Tuina treatment produces larger number of satellite cells than routine Tuina treatment.Conclusion: Early Tuina treatment is helpful to the marked recovery of skeletal muscles by increasing the number of satellite cell.

Objective To provide Laser generator with a precision constant-temperature environment.Method This system was developed on the bases of PT100 sensor circuit,MCU and SSR.The inputting PT100 voltage was first amplified and deflected,and then delivered to AD650 to perform V/F.The outputting frequency was measured with high precision by T0 port of MCU C8051F020,and the micro-controller calculated the result and transmitted PID output signal by 16 bit PWM to heater.Results This precision constant-temperature water circulator was gifted with an error within ?0.05℃.Conclusion This precision constant-temperature water circulator can make an ideal temperature environment available for laser generator.

Objective To investigate the effect of the mild conjunctivitis complication on the tear break-up time(BUT) in pa-tients with dry eye .Methods 93 patients with dry eye from Sep .2007 to Sep .2011 were selected .For all of them the BUT was 5 seconds or less than 5 seconds after corneal fluorescein staining .They were divided into experimental group (with mild conjunctivi-tis) and control group (without mild conjunctivitis) .We checked the BUT and compared the difference of BUT between experimen-tal group and control group .Results The average BUT of the 54 patients with complicated mild conjunctivitis ,of which conjuncti-val papillae was found in 40 cases ,was (3 .54 ± 1 .02)s ,the average BUT of the 39 patients without conjunctivitis was(3 .41 ± 1 .04) s .There was no significant difference between two groups .Conclusion Dry eyes complicated mild conjunctivitis had no effect on BU T .

Mechanosensitive ion channels are mechanoreceptors that convert mechanical stimulation on the cell surface into intracellular electrical signal or chemical signal. In recent years, Piezo protein as a mechanically activated cation channel in eukaryotes has gradually become a research hotspot. Piezo1 and Piezo2 proteins are expressed in different organs and tissues of mammals, and tissues such as bones and joints are directly related to mechanical conduction. The intracellular effects caused by the conduction of mechanical force play a very important role in the treatment and prevention of orthopedic diseases. In this paper, the researches on Piezo protein mechanically activated cation channels in bone tissue, cartilage tissue, bone marrow tissue, intervertebral disc tissue and orthopedic diseases were reviewed.

Objective To investigate the correlation between gene polymorphisms in IL-10 promoter region and the susceptibility and clinical phenotypes of HCV infection. Methods Two groups of subjects were studied. Group 1 included 85 treatment naive patients with chronic HCV infection, and group 2 included 75 healthy blood donors. Genotyping of IL-10 promoter-592 was performed by PCR-RFLP. Results No significant difference was found in IL-10 promoter-592 genotypes between the healthy individuals and HCV-infected patients. However, IL-10 promoter-592 genetype A/A appeared more frequently in patients with ALT≥80U/L than in those with ALT

Objective To study the expression and clinical significance of the SALL4 in human gastric carcinoma tissues. Methods The expression of SALL4 in 91 samples of gastric carcinoma and 37 samples of normal gastric tissues was detected by RT-PCR,Western blot and immunohistochemistry,and its relationship with the clinical data were analyzed statistically.Results The positive expression rate of SALL4 in gastric carcinoma(74.7%)was significantly higher than that(18.9%)in normal gastric mucosa tissues(P <0.05).Moreover,with the decreased with the differentiation of gastric carcinoma,the positive expression rate of SALL4 was increased.The expression of SALL4 mRNA and protein in gastric carcinoma tissues were significantly higher than that in normal gastric tissues(P <0.050).The expression levels of SALL4 were relevant to lymph node metastasis(P =0.001),infiltra-tion depth(P =0.029)and the differentiation degree of gastric carcinoma(P =0.050).Conclusion SALL4 was highly expressed in gastric cancer tissues and relevant to lymph node metastasis,infiltration depth and the differentiation degree,which may have play an important role in the development of gastric cancer.

Objective To construct a scientific and feasible evaluation indicator system of health education effect of our country′s hospitalized patients with diabetes. Methods On the basis of literature review and semi-structured interview combined with group discussion, alternative index system were determined,and then the Delphi method were used for two round consultation with 30 diabetes experts to finally determine indicator evaluation system. Results Positive coefficient of the two rounds consultation were 86.7% (26/30) and 100.0% (26/26) respectively, experts′ authority coefficient was 0.889,and the Kendall W coefficients of concordance were 0.447,0.369 and 0.302 respectively (P<0.01). The evaluation indicator system of health education effect was consisted of 6 fisrt-level indicators, 24 second-level indicators and 55 third-level indicators. Conclusions The evaluation indicator system of health education effect is reliable and scientific, which can provide objective and quantitative standards for health education effect of hospitalized patients with diabetes in our country.
