Objective To investigate the application of respiratory navigator echo triggered black blood contrast FSE in cardiac MRI. Methods The respiratory navigator echo trigger technique combining with black blood FSE (NAV-FSE) was tested on 11 volunteers and 5 patients in free breathing,using breath-hold FSE (BH-FSE) with the same imaging protocals as control. The imaging efficiency and the image sharpness were compared between NAV-FSE and BH-FSE and t-test was used for the statistics. Results All NAV-FSE acquisitions were completed in sixteen subjects while 4 BH-FSE acquisitions failed because of poor breath holding. The efficiencies of NAV-FSE were (42. 95±11.50)%, (56. 14±11.40)% and (55.25± 14. 70)% when echo train length (ETL) were 24, 16 and 8, respectively. When ETL were 16 and 24, the sharpness of NAV-FSE ( 0. 43±0. 02 vs 0. 36±0. 02 ) and BH-FSE ( 0. 36±0. 03 vs 0. 35±0. 02 ) were statistically different (t =4. 26, 5. 53 ,respectively; P <0. 05). NAV-FSE could have a shorter ETL setting without consideration of breath holding. Conclusion The navigator echo trigger technique could be compatible with black blood contrast FSE to image the heart without the restriction of breath holding and it allows to optimize the parameters to improve the image quality.

Objective: To explore the effect of atorvastatin (Atv) on high glucose-induced oxidative stress injury in human umbilical vein endothelial cells (HUVECs) by SIRT1/NADPH oxidase pathway with the possible mechanisms.
Methods: HUVECs were cultured in low glucose medium and then divided into 6 experimental groups:①Normal group,②Osmotic pressure control group,③High glucose (HG) group,④HG+Atv (0.1, 1.0, 10.0)μmol/L group,⑤HG+sirtinol (SIRT1 inhibitor) group,⑥HG+apocynin (NOX4 inhibitor) group, and HUVECs were further cultured for 24 hours. The cell proliferation was examined by CCK-8 kit, ROS level was detected by lfow cytometry method, protein expressions of SIRT1 and NOX4 were measured by Western blot analysis.
Results: ① Compared with Normal group, HG group had decreased HUVECs proliferation, Atv improved the HG inhibited proliferation in a does dependent manner. ② HG group had the higher level of ROS, increased NOX4 protein expression and decreased SIRT1 protein expression. ③ In HG condition, Atv up-regulated SIRT1 expression and down-regulated ROS and NOX4 expressions in a does dependent manner.④In HG condition, sirtinol decreased SIRT1 expression, increased NOX4 expression, and apocynin decreased NOX4 expression, while it had no inlfuence on SIRT1 expression.
Conclusion: Atorvastatin could resist HG-induced oxidative stress injury in HUVECs, which might be related to up-regulated SIRT1 expression, and SIRTI plays the role in NADPH oxidase at upstream.

Objective To investigate the expression of lysyl oxidase like protein?2(LOXL?2)in the sera of patients with active systemic scleroder?ma(SSc)and mixed connective tissue disease(MCTD). Methods An enzyme?linked immunosorbent assay was adopted to measure LOXL?2 in the serum of 20 patients with active SSc,20 patients with active MCTD,and 20 healthy controls. The measurements among different groups was com?pared,and correlations between LOXL?2 levels and clinical manifestations of SSc and MCTD were examined. Results The levels of LOXL?2 ex?pression in MCTD and SSc groups were significantly higher than those in control group(P<0.05 for all groups). LOXL?2 expression is also related to the presence of skin lesions in SSc(r=0.982 P=0.001). Conclusion High serum level of LOXL?2 in these patients with active SSc and active MCTD suggests that LOXL?2 may be involved in the process of fibrosis and the resulting vasculitis in multiple organs.

OBJECTIVE To observe the effects of glycogen synthase 3β (GSK-3β) in the regula-tion of NLRP3 inflammasome activation after acute myocardial infarction (MI) in Sprague Dawley(SD) rats. METHODS Ligation of the left anterior descending (LAD) in SD rats was used to establish an acute myocardial infarction model. SD rats were randomly divided into 3 groups (n=10, each group):sham group,MI group,and MI+SB group:the GSK-3β inhibitor(SB216763)was given 1 h by intrave-nous injection(0.6 mg·kg-1·d-1)before surgery.The serum and heart tissue were collected to measure lactate dehydrogenase (LDH) and IL-1β content and mRNA and protein levels of NLRP3, ASC, Cas-pase-1,IL-1β and GSK-3β after 2 days and 7 days operation,respectively.RESULTS The serum levels of LDH and IL-1β in the MI group were significantly higher than those in the sham group(P<0.01),and the MI+SB group was obviously lower than the MI group(P<0.01).In addition,mRNA and protein levels of NNLRP3, ASC, Caspase-1, IL-1β and GSK-3β expressions in MI group were clearly increased (P<0.01) compared with those in sham group.These indicators were significantly decreased in SB+MI group (P<0.01). Interestingly, the indicators were all higher at 7 days than 2 days. CONCLUSION GSK-3β inhibition induces cardioprotection via attenuating the activation of NLRP3 inflammasome after the acute myocardial infarction in rats.

Objective To evaluate the effect of GTV volume on response of esophageal carcinoma.Methods From Jan.2004 to Dec.2008,72 cases newly diagnosed N0 stage thoracic esophageal carcinomas were included in this retrospective study.All treatment plans were set up and designed by CT simulator and 3D TPS.They received dose 56-70 Gy/27-33F/6-7w with 6MV X-ray.The GTV,the tumor length and maximum diameters were measured on the treatment planning system with the X-ray.RECIST standard was applied to evaluate the radiotherapy response of esophageal carcinoma.The effectiveness of related prognostic factors on survival was evaluated by univariate analyses.Results The short-term response with CR were 79％ with length ＜ 5 cm,48％ with 5-7 cm and 26％ with length ＞7 cm(P =0.003).The 1-,2-,3-and 5-year survival rates were 93％,79％,69％,69％ ; 91％,61％,46％,46％ and 80％,46％,28％,22％ (P =0.037).The short-term response with CR were 56％ with maximum diameters ≤3 cm and 33％ with maximum diameters ＞ 3 cm(P =0.033).The 1-,2-,3-and 5-year survival rates were 91％,72％,55％,37％ and 80％,45％,30％,30％ (P =0.037).The short-term response with CR were 52％ with GTV volume≤40 cm3 and 30％ with GTV volume ＞40 cm3(P =0.059).The 1-,2-,3-and 5-year survival rates were 91％,67％,51％,41％ and 80％,43％,27％,27％ (P =0.047).In the multivariate analysis,the length of GTV was likely to be the most important factor for the short-term response(P =0.005,0.014).Conclusions GTV volume,the tumor length and maximum diameters are factors for short-term response of N0 stage esophageal carcinoma.The GTV length is independent prognostic factor.The GTV length is the worse the prognosis will be.

Objective To explore the evaluation methods of deodorants for patients with axillary odor. Methods Four trained judges used a blind method to evaluate 60 subjects directly or indirectly before and 6 hours and 24 hours after using deodorants. New T-shirts were provided for the subjects each time after grading. Then the judges evaluated the odor from the T-shirt as indirect axillary evaluation method. Then statistic analysis was used to compare the odor changes of axillary odor. Results The odors of axillary area were all decreased by two evaluation methods after using 3 different deodorants. But the efficacy of 3 deodorants were not completely same. Conclusion Direct axillary odor evaluation is a good method to evaluate the efficacy of deodorants.
