The liquid-chromatography-mass technology was used in the metabolomic analysis of mouse's blood 1 hour after exhaustive exercise,in order to explore the potential mechanism of Rhodiola in fatigue elimination of exhaustive exercise mouse.The exhaustive mouse model was made by loaded-swimming.A total of 24 mice were randomly divided into theRhodiola + exercise group,exercise group andno-exercise group.The dose of Rhodiola was 0.4375 g·kg-1·d-1.The loaded-swimming was conducted after two successive weeks of medication.Blood was collected 1 h after swimming for the sample preparation.The enzyme assay and anthrone colorimetry were used to test blood lactate acid and glucose,respectively.UFLC-Q-TOF was used to detect metabolic profiles of each group.The principal component analysis (PCA),orthogonal partial least squares discriminant analysis (OPLS-DA) and heat map analysis were used to compare differences among groups with score chart and to obtain the characteristics biomarkers by load chart.The results showed that the blood lactate acid level of theRhodiola+ exercise group was significantly lower than that of theexercise group.And the glucose level of theRhodiola+ exercise group was significantly higher than that of theexercise group.The metabolomic analysis showed that there were no obvious changes on 1,25-(OH)2D3,diacylglycerol (DG) and inositol triphosphate (IP3).All three materials in theRhodiola + exercise group were significantly lower than those of theexercise group.They were much closer to theno-exercise group.And all three materials were related to the increasing of muscle tension.It was concluded that Rhodiola had the function of promoting fatigue eliminating.This effect may be related to cell membrane protection,regulation of 1,25-(OH)2-D3→IP3,DG pathway,and relieving of muscle tension after exercises.

Background and purpose:The transcription factor PAX6 is primarily expressed in embryos. PAX6 is also expressed in several tumors and plays oncogenic or tumor suppressor role. This study aimed to investigate the expression of PAX 6 in non-small cell lung cancer (NSCLC) tumor samples and cell lines; and evaluate the effects of PAX6 on the proliferation and invasion of tumor cells and the expression level of cyclin E and p38.Methods:Western blot was carried out to detect the PAX6 protein level in 86 NSCLC tumor tissues, paired adjacent normal tissues and 2 cell lines. PAX6 siRNA was transfected into human lung cancer A549 cell line. Anchorage-independent growth and invasiveness of tumor cells were measured by MTT and transwell cell invasion assay, respectively. Cyclin E and p38 protein level before and after transfection were detected by western blot.Results:Comparison with tumor adjacent tissues and normal human bronchial epithelial cells 16HBE, PAX6 in NSCLC tissues and A549 cell lines was signiifcantly higher expression. After transfection with efifcient sequence of PAX6 siRNA for A549 cell lines, the down expression of PAX6 inhibits tumor cell proliferation, the proportion of cells in G1 phase increased, the cell invasion and migration decreased remarkably. Cyclin E and p38 activity was inhibited inPAX6 knockdown cells.Conclusion:PAX6 accelerate cell cycle progression by activating cyclin E and p38. PAX6 is a potential target for diagnosis and therapy.

AIM: To analyze the clinical efficacy and complications of titanium mini plate internal fixation and reconstructive surgery for patients with orbital fracture.
METHODS: Fifty - seven cases (60 eyes) with orbital fracture from March 2013 to April 2014 in our hospital were researched. According to the random number table method, the patients were divided into observation group (29 cases with 30 eyes) and control group (28 cases with 30 eyes ). The control group was treated with hydroxyapatite artificial bone plate for internal fixation, and the observation group with titanium mini plate internal fixation and reconstructive surgery. The diplopia grading, grading of ocular movement disorder before and at 1, 3mo after treatment and postoperative complications ( prolapse, dislocation, infection ) were compared between the two groups.
RESULTS: In both group, all the 60 eyes were healed without scar formation. The rate of diplopia grading as grade 0 1mo postoperatively of observation group and the control groups were 63% and 40% ( P < 0. 05); diplopia grading 3mo postoperatively and the eye movement barrier obstructs 1 and 3mo postoperatively of observation group were better than those of the control group ( P <0. 05). The adverse reaction rate of observation group and control group were 3% and 20% (P<0. 05).
CONCLUSION: The clinical curative effect of titanium mini plate internal fixation and reconstructive surgery has a good effect for orbital fractures, which can improve the therapeutic effect and reduce the incidence of adverse reactions.
