ABSTRACT
Objective:To investigate the changes of serum catecholamines (CST) and oxidative stress index in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) with hypertension and the correlation with blood pressure.Methods:Total of 100 OSAHS patients admitted to Jingmen No.1 People′s Hospital from February 2018 to August 2020 were selected. According to whether patients combined with hypertension, they were divided into OSAHS group (54 cases) and OSAHS combined with hypertension group (46 cases). The changes of serum CST and oxidative stress index in the two groups were compared and analyzed the correlation of blood pressure and CST and oxidative stress index.Results:The level of myeloperoxidase(MPO) in the OSAHS combined with hypertension group was higher than that in the OSAHS group: (41.67 ± 3.02) U/L vs. (39.11 ± 2.65) U/L; the levels of catalase (CAT) and CST in the OSAHS combined with hypertension group were higher than those in the OSAHS group: (11.47 ± 2.54) kU/L vs. (15.88 ± 2.31) kU/L, (23.63 ± 4.38) ng/L vs. (28.61 ± 5.42) ng/L, there were statistically differences ( P<0.05). The levels of respiratory disturbance index, lowest oxygen saturation, triacylglycerol, total cholesterol, low density lipoprotein cholesterin, high density lipoproteincholesterol, epinephrine, noradrenaline in the two groups had no significant differences ( P>0.05). Spearman correlation analysis showed that the systolic pressure and diastolic pressure had positive correlation with MPO ( P<0.05), and had negative correlation with CAT and CST ( P<0.05). Conclusions:The serum CST and CAT are down-regulated in patients with OSAHS with hypertension, and serum MPO is up-regulated. Oxidative stress may be related to OSAHS with hypertension.
ABSTRACT
Objective:To investigate the relationship between the expression of serum exsomal miRNA-155-5p (miR-155-5p) and prognosis in patients with esophageal squamous cell carcinoma (ESCC).Methods:A total of 336 samples from ESCC patients in Fujian Provincial Cancer Hospital from October 2014 to December 2015 were collected. The relative expression levels of serum exsomal miR-155-5p were detected by using real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). Cut-off value of the expression levels of serum exsomal miR-155-5p was determined by using X-tile software. Based on the optimal cut-off value, patients were divided into miR-155-5p low expression group and miR-155-5p high expression group. The survival curve was drawn by using Kaplan-Meier method and Cox proportional hazards regression model was used to make survival analysis.Results:The cut-off value of serum exsomal miR-155-5p expression level was 2.340. According to the cut-off value, patients were divided into miR-155-5p low expression group (<2.340) of 51 cases and miR-155-5p high expression group (≥2.340) of 285 cases. There were no statistical differences in age ( χ2 = 0.020, P = 0.887), gender ( χ2 = 0.283, P = 0.595), tumor location ( χ2 = 0.063, P = 0.977), differentiation grade ( P = 0.474), clinical staging ( χ2 = 3.996, P = 0.136) and surgery treatment ( χ2 = 0.941, P = 0.332) of patients in both groups. ESCC patients in serum exsomal miR-155-5p high expression had a higher risk of death compared with patients in miR-155-5p low expression group ( HR = 1.763, 95% CI 1.049-2.961, P = 0.032). Conclusion:The high expression level of serum exsomal miR-155-5p is associated with poor prognosis in ESCC patients and it could be used as a prognostic new marker in ESCC patients.

ABSTRACT
Objective:To study the scavenging activity of macroporous resin isolate of gynostemma pentaphyllum on free radical DPPH. Methods:The extract of gynostemma pentaphyllum via water boiling and precipitation with ethanol was separated by macro-porous resin respectively eluted by water, 40% ethanol and 80% ethanol to obtain the corresponding isolates. The antioxidant activity of the three isolates was determined by free radical DPPH systematic method, and the results were compared with that of gallic acid and ascorbic acid. Results: The 50% inhibitory concentration on free radical DPPH of the three isolates was 0. 081 2, 0. 028 7 and 0. 541 0 g·L-1 ,respectively. The 40% ethanol isolate had the highest saponins concentration. Conclusion:The macroporous resin i-solate with different solvent all shows antioxidant activity and the 40% ethanol isolate has the strongest effect, suggesting saponins may be the active substances for the lipid-lowering, hypoglycemic and free radical scavenging activities.
ABSTRACT
To evaluate five methods in the estimation on the rate of case fatality during the epidemics of diseases based on the summarizing data. Case fatality rates, derived from the simulation data, 2003 SARS epidemic data in Hong Kong, Singapore Beijing and the 2013 H7N9 epidemic data in mainland China were analyzed, using these 5 methods. Results from the simulation analysis discovered that the relative errors and the standard deviations of the Chen [7, 8] (method 3), Chen [9] (method 4)were minor with high accuracy. Data from the analysis on 2003 SARS epidemic was noticed that the estimation from method 3, 4 in Hong Kong and Singapore both showing high veracities. Since the case fatality rate reported in Beijing was not a constant value, method 5 showed low accuracy even though it was close to the final case fatality rate. Data from the 2013 H7N9 epidemic showed that the estimations of method 1, 2, 3, 4 were all higher than that in the method 5, suggesting that method 3, 4 could be used to estimate the case fatality rates of epidemics more precisely.

Low shear stress is a component of the tumor microenvironment in vivo and plays a key role in regulating cancer cell migration and invasion. The integrin, as a mechano-sensors mediating and integrating mechanical and chemical signals, induce the adhesion between cells and extracellular matrix (ECM). The purpose of this study is to investigate the effect of low shear stress (1.4 dyn/cm2)on the migration of HepG2 cells and the expression of integrin. Scratch wound migration assay was performed to examine the effect of low shear stress on the migration of HepG2 cells at 0 h, 1 h, 2 h and 4 h, respectively. F-actin staining was used to detect the expression of F-actin in HepG2 cells treated with low shear stress at 2 h and 4 h. Western blot analysis was carried out to determine the effect of low shear stress on the expression of integrin at different durations. The results showed that the migrated distance of HepG2 cells and the expression of F-actin increased significantly compared with the controls. The integrin alpha subunits showed a different time-dependent expression, suggesting that various subunits of integrin exhibit different effects in low shear stress regulating cancer cells migration.
