Clinical Study on Pingwei Capsules for 45 Cases of Chronic Atrophic Gastritis with Precancerous Lesions of Gastric Cancer
Objective To observe the efficacy and mechanism of Pingwei Capsules for chronic atrophic gastritis with precancerous lesions of gastric cancer( PLGC). Methods Totally 100 cases of PLGC were randomized into the treatment group and control group
with 50 in each. There were 5 cases excluded and 45 cases remained in the treatment group. There were 15 cases excluded and 35 cases remained in the control group. The treatment group was given Pingwei Capsules( 4 caps once and three times daily). The control group was given Vitacoenzyme Tablets( 4tablets once and three times daily). The treatment lasted for 6 months. The symptoms
gastroscope results and the expressions of vascular endothelial growth factor( VEGF) and CDX2 were observed before and after treatment in both groups. Results The total effective rate of the treatment group and control group was 91. 1% and 77. 1% respectively
with a significant difference between groups( P < 0. 05). After treatment
the symptom scores were significantly decreased in both groups( P < 0. 05)
especially in the treatment group( P < 0. 05). The pathological improvement rate in the treatment group and control group was 51. 1% and 31. 4% respectively
with a significant difference between groups( P < 0. 05). After treatment
the improvement rates of erosion
mucosal Shiraai
particle hyperplasia
vascular permeability and bile reflux in the treatment group were superior to those in the control group( P < 0. 05).The expression of VEGF was significantly decreased after treatment in both groups( P < 0. 05). There was no significant difference between groups in the expression rate of VEGF( P > 0. 05). After treatment
the positive expression rate of CDX2 in type I intestinal metaplasia( IM)
type Ⅱ IM and dysplasia was significantly decreased in the treatment group( P < 0. 01). After treatment
the positive expression rate of CDX2 in type I IM and type Ⅱ IM was significantly decreased in the control group( P < 0. 01). After treatment
the positive expression rate of CDX2 in type I IM and type Ⅱ IM in the treatment group was significantly lower than that in the control group( P < 0. 05).Conclusion Pingwei Capsules can effectively relieve the symptoms and pathological changes of PLGC patients
promote the expression of VEGF
improve gastric blood circulation
strengthen and repair the mucosal regeneration
inhibit the expression of CDX2 and reverse precancerous lesions.
