Objective To discuss the effect and related mechanism on epithelial?mesenchymal transition(EMT)process and invasive ability of the trophoblasts JEG?3 by targeted silencing of Notch?1 gene. Methods Notch?1?siRNA interference fragment was designed and synthesized to sta?bly transfect JEG?3 cells. Changes in the invasive ability of trophoblasts were detected by Transwell chamber invasion assay. The expressions of Notch?1 ,E?cadherin ,vimentin and EMT transcriptive regulators slug ,snail ,twist were analyzed in transfected trophoblasts by Western blot. Results The relative expression of Notch?1 protein in JEG?3 and the invasive ability of JEG?3 were significantly decreased after transfection with Notch?1?siRNA,the expression of the epithelial indictor E?cadherin was significantly increased while the mesenchymal indicator vimentin was de?creased with the reduction of EMT transcriptive regulators slug,snail and twist. Conclusion The invasion of trophoblasts was affected by targeted si?lencing of Notch?1 gene and Notch?1 can reduce the invasion of trophoblasts through influencing EMT process.

BACKGROUND:Transgenosis of basic fibroblast growth factor (bFGF) gene has been successfully performed into the muscle satellite cells of rat extraocular muscles in the previous study of the research group, proving that bFGF could express in the myoblasts of extraocular muscles, also promote cell proliferation and differentiation.OBJECTIVE: To further investigate the methods for regulating the expression of the bFGF in myoblasts following transfection. METHODS: Target gene bFGF was connected with inducing expression vector pcDNA4/T0/myc-His?A, followed by masculine clone sequencing identified by colony PCR and enzyme digestion, EcoR I and Hind III restriction enzyme digestion, as well as Xho I single enzyme verification. C2C12 myoblasts antibiotics sensitivity was screened and finally defined. By use of lipofection transfection technology, cell lines where C2C12 stably expressed pcDNA6/TR were estabolishd and then identified by Western blot. The pcDNA4/TO/myc-His?A-bFGF was transfected into pcDNA6/TR- C2C12 cells. The bFGF expression and secretion in C2C12 cells following tetracycline-induced pcDNA4/TO/myc-His?A-bFGF transfection were determined by immunofluorescence and Western blot, the controls were established.RESULTS AND CONCLUSION: ① The conjunction between the bFGF and inducing expression vector pcDNA4/TO/myc-His?A was proved successfully by sequencing comparison, double digestion and single digestion. ②The minimal lethal concentration of blasticidin to C2C12 cells was 10 mg/L, while that of zeocin was 750 mg/L. ③ The pcDNA6/TR-C2C12 cell lines were established correctly. ④ The myoblasts treated by tetracycline and transfected with pcDNA4/TO/myc-His?A-bFGF were positive for gene expression, those untreated exhibited a negativity; bFGF protein could be produced in myoblasts treated by tetracycline and transfected with pcDNA4/TO/myc-His?A-bFGF, the production reached a peak at 24 hours, while those untreated can not produce bFGF protein. Results suggest that the bFGF expression in the myoblasts can be controlled by tetracycline inhibition and regulatory systems.

Objective To investigate the relationship between depression and trait coping style in Chongqing middle school students.Methods Self-Rating Depression Scale (SDS) and Trait Coping Style Questionnaire (TCSQ) were adopted in the study to test the randomly sampled 1 596 middle school students of Chongqing.Results Students’ depression rate was a little bit high (58.4%).The differences in depression (41.20?7.83),other factors [psychological disorder (3.30?1.36),physical disorder (15.19?3.01),psychomotor disturbance (4.43?1.25) and mental disorder (18.27?4.70)],and trait coping style [positive coping style (29.5?8.5) and negative coping style (23.0?7.8)] was significant among genders,grades and school types.Students’ depression was in correlation with positive (besides psychological disorder factor,r=-0.483,-0.267,-0.272,and-0.553) and negative coping style (r=0.242,0.618,0.175,0.190,and 0.098) in different degrees.Coping style was a valuable predictor of students’ depression.Conclusion Students’ depression is significantly correlated to trait coping style in middle school students.Positive coping style can reduce the rate of student’s depression.

Objective:To explore the reasonable amount of bacteriostatis agent in fluconazole eye drop. Methods: According to the method of bacteriostatis effect test in 2015 edition of Chinese Pharmacopoeia (ChP), and Staphyococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candia albicans and Aspergillus niger as the test strains, the bacteriostatis effect of fluconazole eye drop containing 5%, 1%, 0. 3% and 0. 1% benzalkonium chloride was determined. Results: The bacteriostatis effects of fluconazole eye drop containing 5%, 1% and 0. 3% benzalkonium chloride on the five species of tested bacteria complied with the regulations of ChP. The bacteriostatis effects of 0. 1% benzalkonium chloride on Pseudomonas aeruginosa didn't meet the requirements, therefore, 0. 3%was the minimum inhibitory concentration ( MIC) of benzalkonium chloride. Conclusion: The best inhibitory concentration of benza-lkonium chloride is 1%.

Objective To explore the direct association between metabolic syndrome (MS) and gamma glutamyltransferase (GGT) or alanine aminotransferase (ALT) in Beijing men and women.Methods We investigated the medical check-up data from the 14,204 physical examination population (male 9524,female 4680) of year 2008.A cross-sectional study was carried out to explore the direct association between MS and GGT or ALT.MS was defined by the Chinese Diabetes Society (2004).Chisquare test was performed to analyze the categorical variables.The receiver operating characteristic curve (ROC) was plotted to obtain area under curve (AUC) and the cutoff point of GGT and ALT.Results The prevalence of MS was significantly higher in subjects with the highest quartile of GGT or ALT than the subjects with the lowest quartile of GGT or ALT.For male,the prevalence of MS is 7.57％ in the lowest GGT quartile and 29.04％ in the highest GGT quartile.For female,the prevalence of MS is 1.28％ in the lowest GGT quartile and 17.86％ in the highest GGT quartile.For male,the prevalence of MS is 9.27％ in the lowest ALT quartile and 21.88％ in the highest ALT quartile.For female,the prevalence of MS is 3.52％ in the lowest ALT quartile and 14.70％ in the highest ALT quartile (P ＜0.01).The optimal cutoff points of GGT to diagnose MS were 31 U/L in men and 18 U/L in women.The optimal cutoff points of ALT to diagnose MS were 23 U/L in men and 19 U/L in women.Conclusions The prevalence of MS increases with the increase in serum levels of GGT or ALT even through the normal range of GGT or ALT in Chinese men and women.

Objective To investigate the mental health status of middle school students in Three-Gorge area in Chongqing, and to explore the relationship with their life events and coping styles. Methods The Compi-ling of mental health scales for middle school students(MSSMHS),adolescent self-rating Life events checklist and trait coping style questionnaire(TCSQ) were adopted in the study to test the randomly sampled 1 632 middle school students in Three-Gorges area in Chongqing. Results The rate of mental disorder in the samples was 27.5%. The total average scores and each factor of the mental health were positively correlated with the factors of life events(r=0. 29～0.55). Negative coping styles were positively correlated with the total average scores and each factor of the mental health (r=0.38～0.56). Positive coping styles was negatively correlated with anxiety, depression, study pressure(r=-0.07～-0.05). The factors of life events and coping styles explained 27%～49% variation of scores of the mental health total average scores and each factor of the mental health. Conclusion Both life events and the coping styles are the important factors for the mental health of middle school students in Three-Gorge area in Chongqing. Reducing negative life events and coping styles benefits the mental health of middle school students.

Objective To observe the effects of over-expression of matrix metalloproteinase-12 (MMP-12) on the transformation of pulmonary fibroblasts in radiation damaged rats. Methods Thirty-two male Wistar rats (weighed 250-280g) were randomly assigned into control group and 1, 2 and 4 weeks after irradiation groups (8 each). The whole lungs of rats in irradiation groups were irradiated by 60 Co ?-ray at a dose of 20Gy, and the lung specimens were harvested 1, 2 and 4 weeks after radiation. The change of MMP-12 activity was detected by gelatin zymography, the degradation and collapse of elastic fibers were observed by tissue specific staining, the "cross talking" phenomenon between alveolar type Ⅱ cells and mesenchymal cells was observed by transmission electron microscopy, the content of TGF-?1 was determined by ELISA, and the expression of ?-smooth muscle actin (?-SMA) was examined by immunohistochemistry. Results MMP-12 activity began increasing 1 week after irradiation, and seemed to decrease 4 weeks after irradiation. Elastin, a part of the basement membrane of alveolar wall, began to degrade and collapse 1 week after radiation, and became worse 4 weeks after irradiation. The expressions of both TGF-?1 and ?-SMA were elevated gradually within 4 weeks after radiation. The "cross talking" phenomenon was found by electron microscopy between alveolar type Ⅱ cells and mesenchymal cells. Conclusions Increased activity of pulmonary MMP-12 has been found after radiation, which may promote the transformation of pulmonary fibroblasts by degrading elastin and ultimately initiate the pulmonary fibrosis.
