AIM： To investigate the effect of Auricularia Polytricha Sacc Polysaccharide（ APSP） on protein kinase A（ PKA） activity in murine peritoneal macrophages METHODS： New ion－ pair RP－ HPLC method was used to determinate the activity of PKA in murine peritoneal macrophages RESULTS： APSP（ 80mg/L） induced activation of PKA in murine peritoneal macrop_ hages； the peak appeared at 8 minutes and the activity of PKA returned to the basic level at 20 minutes CONCLUSION： The immunopoteniating effect of APSP may be associated with its activating effect on PKA in murine peritoneal macrophages

Objective We undertook this study to analyze anxiety in tinnitus patients .Methods The partici‐pants were recruited from patients seeking treatment for primary tinnitus and were asked to complete self rating anx‐iety scale(SAS)and Chinese (Mandarin) tinnitus handicap inventory(THI -CM) .Results A total of 224 tinnitus patients were included in the study .The mean score of SAS was 46 ± 2 .55 .The average SAS score among different degrees of anxiety (no ,mild ,moderate ,severe) participants were 65 .63% ,20 .54% ,8 .04% ,5 .80% .The average SAS score for male and female were 46 .35 ± 12 .81 ,46 .28 ± 12 .40 ,respectively .No statistic differences were ob‐served among different genders whenever the degrees of anxiety and different ages (p>0 .01) .The mean SAS scores among young ,middle ,old age groups were 47 .72 ± 12 .80 ,44 .56 ± 12 .83 ,40 .28 ± 7 .24 ,respectively .The pearson correlation between tinnitus duration and the score of SAS was 0 .36(P=0 .594) .The pearson correlation between the scores of THI-CM and SAS was 0 .548(P<0 .01) .Conclusion Most tinnitus participants had mild or didn't have anxiety .Only 13 .84% participants have moderate or severe anxiety .Tinnitus handicap degree increased with the increase of anxiety .No anxiety difference was observed among different sex ,tinnitus duration and age groups . The anxiety of young age group was more severe than that of old groups .
