AIM: To investigate electroacupunture(EA) at the acupoints of Stomach Meridian of Foot-Yangming(SMFY),Gallbladder Meridian of Foot-Yangming(SMFY) on gastric mucosal intestinal trefoil factor (ITF) gene expression detection in stress-induced rats with gastric mucosal lesion, and to explore the regulatory mechanism and significance of EA-related gastric mucosal protective effect.METHODS: Forty rats were randomly divided into 4 groups: Blank group, Model group, Model group+EA at acupoints of SMFY group("SMFY group"), and Model group+EA at acupoints of GMFY group(GMFY group).All rats (except blank group) were made model by water immersion and restraint stress (WRS). Then the gastric mucosa tissue in each rat was taken off after assessment of gastric mucosal lesion index(GUI), and the expression of ITF mRNA of the tissues was detected by reverse transcription-polymerase chain reaction(RT-PCR) method.RESULTS: Compared with Model group(54.3 ± 1.34),the GUI value in SMFY group (31±2.21) decreased significantly(P< 0.01), so did that in GMFY group (39.8±1.62, P
