The adverse effects of more than two groups found, two groups of patients with adverse reaction incidence was no significant difference, that shows no significant difference. Conclusion Mosapride citrate in reflux esophagitis treatment and intervention effect analysis found that the compared with conventional therapy, can be in At the same time, it can improve the curative effect of the patients, and will not increase the possibility of adverse reactions, so it is worthy of clinical reference.

Objective To study the relationship between the mutation of androgen receptor(AR) gene and the development of human prostat e cancer. Methods All exons of AR gene except trineucl eic acid repeat polymorphism were amplified by PCR and selected by single strand conformation polymorphism( SSCP) in 27 paraffin-embedded slides of human pros tate cancer. The abnormal mobility shifts were further detected by direct DNA c ycle sequencing. Results Three abnormal mobility shifts respectively in exon A.D.G were found by SSCP in three prostate cance r tissues. One point mutation was found in 296 amino acid (C 966→A,Ser29 6Arg) from exon A.This point mutation has not been reported before. Conclusions This mutation might change the transcriptive activity of AR, and it might be correlated to PCa progression.
