ABSTRACT
The aim of this work is to discover the inhibitory mechanism of tea peptides and to analyse the affinities between the peptides and the angiotensin-converting enzyme (ACE) as well as the stability of the complexes using in vitro and in silico methods. Four peptide sequences identified from tea, namely peptides I, II, III, and IV, were used to examine ACE inhibition and kinetics. The half maximal inhibitory concentration (IC
ABSTRACT
Objective To investigate the clinical effect of the treatment of senile chronic superficial gastritis with the treatment of the elderly patients.Methods Collected in our hospital diagnosed by endoscopy in 80 elderly patients with chronic superficial gastritis were randomly divided into control group and treatment group, 40 cases in each group, the control group using ranitidine therapy, treatment group with teprenone treatment, evaluation of 2 groups of drugs on chronic superficial gastritis and therapeutic effect safety.Results The total effective rate of treatment group was 92.5%, control group total effective rate was 75%;the treatment of two patients with total efficiency, the total effective rate in treatment group was significantly higher than the control group(x2=4.50, P0.05).Conclusion It is safe and effective for the treatment of chronic superficial gastritis in elderly patients.
ABSTRACT
Objective To study the preventive effect of Omeprazole on post-endoscopic retrograde choledo-chopallcreatography(ERCP)-induced pancreatitis.Methods 126 patients were divided into two groups at random.One group received Omeprazole 20mg bid for two days.and the other group received placebo(Vitamine B).Blood was drawn in each group the day before,4 hours and 24 hours following ERCP for examination of amylase and hepa-torenal functions.Meanwhile Meanwhile the clinical manifestations of acute pancreatitis were also observed.Results Acute pancreatitis was clinically induced in 1.59% cases of placebo group,but none in the Omeprazole group.Hyperamy-lasemia occurred in 20.63%-7.93%in Omeprazole group at 4 hours and 24 hours after ERCP operation,while 30.16%.14.29%in placebo group;The incidence rate of acute pancreatitis following ERCP and hyperamylasemia 4 h after ERCP in omeprazole group were significantly lower than in placebo group(P<0.01,P<0.05).There were no significance differences in amylase 24 hours following ERCP between two groups(P>0.05).Concluslon Omeprazole can prevent the acute pancreatitis induced by ERCP to some extent.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of Ganxian recipe (GXR) and lamivudine (LVD) in a two-year treatment of chronic hepatitis B (CHB).</p><p><b>METHODS</b>One hundred and twenty patients with CHB were randomly divided into the combinedly treated group (combined group) of 40 CHB patients who were treated with GXR combined with LVD. Another 40 CHB patients were treated with LVD alone (WM group), and still another 40 CHB patients were treated with GXR alone (TCM group). All these cases were randomly controlled and observed for two years.</p><p><b>RESULTS</b>Comprehensive efficacy: Total effective rate of the combined group (complete response and partial response) was 92.5%, while that of the WM group was 67.5% and TCM group 57.5%, respectively, with the difference between them was significant (P < 0.01); after treatment, the hepatic functions (AST, ALT, SB) of the three groups were all reduced, and the reduction in the combined group was particularly significant in comparison with the WM group or TCM group, P < 0.05 or P < 0.01 respectively, suggesting that the effect in the combined group was better than that in the other two groups; the rate of tyrosine-methionine-aspartate-aspartate (YMDD) virus mutation: it was 7.5% in the combined group, 40.0% in the WM group, and 5.0% in the TCM group; liver fibrosis improvement parameter: after treatment, the results in the combined group got better than those in the other two groups.</p><p><b>CONCLUSION</b>GXR could inhibit the appearance of YMDD after long-term application of LVD, and combined use has marked synergism.</p>
