TH gene expression in IBS patients with different mood disorder

IBS patients	TH mRNA	IBS patients	TH mRNA
SDS > 50 (n = 12)	0.01603 ± 0.0095	SAS > 50 (n = 10)	0.02173 ± 0.01328
SDS < 50 (n = 17)	0.1235 ± 0.103	SAS < 50 (n = 19)	0.1001 ± 0.0839
P	0.042	P	0.366

Compared with IBS patients with lower SDS, the TH gene expression decreased significantly in IBS patients with higher SDS. But no significant difference of TH gene could be seen between IBS patients with higher and lower SAS
