ABSTRACT
Objective To evaluate the role of miR219‐2‐3p in gastric cancer and the underlying mechanisms .Methods Real time RT‐PCR was employed to quantify the expression level of miR219‐2‐3p in matched tissues of 82 patients .In vitro cell proliferation , the expression of tumorgenesis related protein ERK1/2 was performed by overexpressing miR‐219‐2‐3p in gastric cancer cell line MGC803 .Results The expression level of miR‐219‐2‐3p significantly decreased in late stage gastric cancer (P< 0 .05) .The cell proliferation rate was significantly reduced in gastric cancer cell lines overexpressing miR‐219‐2‐3p .Furthermore ,the expression level of p‐ERK that activated form of ERK was significantly decreased whereas the total level of ERK was unchanged after overex‐pressing of miR‐219‐2‐3p in MGC803 cell lines .The expression level of p‐ERK was also increased in gastric cancer tissues .Conclu‐sion miR‐219‐2‐3p may acts as a tumor suppressor in gastric cancer by decreasing the activity of ERK 1/2 signaling pathway .
ABSTRACT
Objective To study the regiments of continuous subcutaneous insulin infusion (CSII) in admitted type 2 diabetic patients, and to analyse the factors related to its effectiveness and insulin dosage. Methods A total of 1 276 type 2 diabetic patients were treated by CSII. The total efficacy of CSII was evaluted. The use of CSII was also analysed in the newly diagnosed patients, elderly patients, and patients with obese or infectious disease. Results The excellent control of blood glucose were achieved in (5.7±2.6)days in the dosage more early and quickly in the newly diagnosed group than that in the previously diagnosed group after the blood glucose levels achieved good control. The percentage of the patients reached the clinical relieve was also higher in the newly diagnosed group. The incidence of hypoglycemia was significantly higher in the elderly patients with lower basal insulin dosage at night. The bolus insulin dosage in the obese patients was higher than that in the non-obese patients. The patients with infectious disease usually have a higher basal insulin dosage than those without infectious disease. The days needed for achieving good control of blood glucose and the insulin dosage were related to infectious factors, the basal blood glucose and obesity. Conclusion The application of CSII among the patients is varied with different conditions. Blood glucose level, body mass index and infection factors are important to determine the initial insulin dosage.
ABSTRACT
Statins is first choice of hypercholesteroiemia. Recently, clinical investigations have shown that statins can correct blood pressure in hypertension patients accompanied with lipid abnormalities. This result can be observed not only in untreated patients but also in patients treated with antihypertensive drugs. But some researches did not support this result completely. To some extend, the mechanisms responsible for the hypotensive effect seem to be largely independent on the effect of statins on lipid profile, and may be related to the improvement of endothelial function and the regulation of angiotensin II receptors.
