RESUMEN
This study aimed at investigating the effects and mechanisms of 7-O-succinyl macrolactin A in inhibi-ting human lung cancer. After treatment of human lung cancer cell lines H460 with 7-O-succinyl macrolactin A, MTS assay was employed to determine cell proliferation;crystal violet staining was used to detect cell adhesion of H460;transwell chamber assay and wound healing assay were performed to evaluate cell invasion and migration;and flow cytometry assay was adopted to evaluate cell cycle. Western blotting and real-time PCR were also employed to determine the expression of β-catenin, c-Myc, Cyclin D1, vimentin, N-cadherin, CD44, integrin β1, Bcl-2 , Survivin and MMP-2/9. The phosphorylation of AKT and mTOR was determined as well. In vitro prolifera-tion of H460 was inhibited significantly by 7-O-succinyl macrolactin A. Cell adhesion, invasion and migration abilities were also attenuated. Western blot and real-time PCR showed that the expressions of β-catenin, c-Myc, cyclin D1, vimentin, N-cadherin, CD44, integrin β1, Bcl-2, Survivin and MMP-2/9 were down-regulated by 7-O-succinyl macrolactin A. It was also found that phosphorylation of AKT and mTOR was inhibited by 7-O-succinyl macrolactin A. 7-O-succinyl macrolactin A can inhibit the in vitro growth and invasion of human lung cancer cell lines H460.
RESUMEN
Objective To investigate the relationship between gallbladder stone with blood lipid levels ,body weight index (BMI) and distribution of TCM constitution .Methods A total of 698 cases of gallstone in our two hospital from September 2013 to February 2015 were selected as the experiment group ,and contemporaneous 253 cases of abdominal hernia ,gallbladder polyp and other diseases were included into the control group .The TCM constitution identification investigation was performed and the TCM constitution distribution was observed .The blood lipid levels and BMI were compared between the two groups .The risk of blood lipid level and BMI to gallstone occurrence was evaluated .Results The normal constitution in the experimental group accounted for 12 .2% ,the top three places of the biased constitution were phlegm‐damp nature ,Qi deficiency nature and damp heat nature ,which accounted for 29 .4% ,17 .0% and 11 .0% respectively .The TC and VLDL‐C level and BMI in the male and female patients of the experiment group were higher than those in the control group ,moreover the TG level in the female patients of the experiment group was significantly higher than that in the control group ,the difference was statistically significant (P< 0 .05) .The increase of TC (OR=2 .87) ,VLDL‐C(OR=6 .32) and BMI (male:OR=2 .43 ,female:OR=2 .01) were the risk factors of gallstone occurrence . Conclusion Increase of TC ,VLDL‐C and BMI are the risk factors of gallstone occurrence ,the TCM constitution of gallstone pa‐tients is dominated by the phlegm‐damp nature .
RESUMEN
Objective To explore the visinin-like protein-1 (VILIP-1) levels in the blood in the Alzheimer disease (AD) and mild cognitive impairment (MCI) due to AD patients,and also to explore its feasibility as a biomarker for the early diagnosis of AD and for the detection of progression of AD.Methods Fifty-eighty participants were included:20 cases for AD group,19 cases for MCI due to AD group,19 cases for normal control group.The level of VILIP-1 was tested by the ELISA method.Results The level of VILIP-1 in AD group was significantly higher than that in normal control group and MCI due to AD group:(9.0 ± 2.9) ng/L vs.(3.3 ± 1.7) and (6.5 ± 3.1) ng/L,and that in MCI due to AD group was significantly higher than that in normal group,there were statistical differences (P ＜ 0.01).The MMSE score in AD group was significantly lower than that in normal group and MCI due to AD group:(15 ± 3) scores vs.(27 ± 2) and (23 ± 2) scores,and that in MCI due to AD group was significantly lower than that in normal group,there were statistical differences (P ＜ 0.01).The level of VILIP-1 was negatively correlated with MMSE score (r =0.463,P ＜ 0.01),but positively correlated with age (r =0.417,P =0.01).Conclusions With the progression of the disease,the cognitive impairment of the AD patient is decreasing.VILIP-1 increased in the blood of the patients of AD and MCI due to AD.It means that the blood VILIP-1 could be a new and potential biomarker for the early diagnosis of AD,and it may be clinical useful for the early diagnosis and effective detection of AD to some extent.
RESUMEN
Objective To investigate the level of plasma malondialdehyde (MDA)and coenzyme Q10 (CoQ10)in patients with type 2 diabetes mellitus,diabetic leg ulcer(DLU).Methods The DLU group consisted of 15 patients with leg ulcers and type 2 diabetes mellitus (7 men and 8 women).The diabetes group consisted of 15 patients with type 2 diabetes mellitus (8 men and 7 women).Ten healthy individuals,age and sex matched with the patients,were used as a control group.Laboratory investigations in the form of glycosylated hemoglobin,plasma MDA and plasma CoQ10 were assessed for all patients and controls.Results The study revealed that in the diabetes group,especially in the DLU group,the MDA level [(7.07 ±3.15)μmol/L and (3.15 ±2.66)μmol/L]was signifi-cantly higher than control group [(4.28 ±0.41)μmol/L]and the index difference between them (F =104.675,P <0.01),while CoQ10 levels in the two groups data[(0.33 ±0.16)mg and (0.16 ±0.16)mg ]were significantly lower than the control group [(0.86 ±0.13)mg](F =46.709,P <0.05).Conclusion Type 2 diabetic patients, especially with DLU,are at increased risk of oxidative stress manifested by increased plasma MDA.
