The levels of TGF-β1 in hypertensive renal function impairment patients and its clinical value analysis / 中国医学装备

Objective:To detect the levels of TGF-β1 in hypertensive renal function impairment patients and its clinical value. Methods: Primary hypertension patients with no target organs damage were enrolled in control group, primary hypertension patients with renal function stageⅠand stageⅡwere enrolled in renal function stageⅠgroup and stageⅡgroup. Serum TGF-β1 levels and renal function indices of three groups were compared. Results:There were no significant difference of serum creatinine and blood urea nitrogen of three groups(F=23.523, P<0.05);endogenous creatinine clearance rate of renal functionⅠandⅡgroups were lower than that of control group, TGF-β1 levels of renal functionⅠandⅡ groups were higher than of control group; TGF-β1 levels were negatively correlated with creatinine clearance rate. Conclusion:TGF-β1 level is an ideal index to reflect renal function for its level significantly changes in renal damage stageⅠ,Ⅱand has good correlation with Cin.

Analysis on the factors influencing the serum potassium concentration changes before and after massive blood transfusion and transfusion hyperkalemia occurred / 中国医学装备

Objective: To study the changes of blood transfusion and blood potassium concentration and the occurrence of hyperkalemia after transfusion factors influence. Methods: In our hospital from 2010 April to select the diagnosis and treatment of -2012 in April 132 cases of non crush injury patients, these patients were randomly divided into two groups, the control group without blood transfusion therapy group, the observation group for massive transfusion treatment group, changes of serum potassium were compared between the two groups before and after transfusion, and to analyze the related effect factors. Results:The serum potassium levels showed no significant difference between the two groups of patients before and after blood transfusion, operation process, but the postoperative within 12h, observation of blood potassium level group were significantly higher than that in control group, the difference is significant, with statistical significance (t=1.562, P<0.05), in addition to 12h after operation, blood potassium levels between the two groups no significant difference. Conclusion: The clinical blood transfusion is not the main cause of hyperkalemia in patients with, but there are still some patients in massive transfusion potassium increased, therefore, in the process of transfusion, or to close monitoring and observation of the serum potassium level, but also to pay attention to changes in renal function, has ruled out the elevation of serum potassium results in impaired renal function because, in order to reduce the incidence of complications.

Expression of CA199,CA724 and CEA in gastric cancer and clinical significance / 中国实用内科杂志

Objective To explore the express levels of CA199,CA724 and CEA in different gastric mucosa pathological situation.Methods The experimental group included 82 cases including 15 of chronic atrophic gastritis,15 of intesti- nal metapiasia,15 of dysplasia of the gastric mucosa,19 of gastric ulcer,18 of gastric cancer;15 of the chronic Super- ficial gastritis (CSG) were set as control group.To test express levels of CA199,CA724 and CEA in these cases by the immunohistochemistry technology.Results The positive rate of CA199,CA724 and CEA in gastric cancer was sig- nificantly higher than that in precancerous lesion groups and precancerous state groups (P0.05),but there was a graduate increasing of the positive rate of CA199,CA724 expression in chronic atrophic gastritis,intestinal metaplasia and dysplasia of the gastric mucosa. Conclusion That different expression of CA199,CA724 and CEA in gastric cancer development situation may be help- ful for the early diagnose of gastric cancer.
