AIM: To study the relationship between piwei damp-heat syndrome and aquaporin 4 (AQP4) from fluid metabolism in patients with chronic superficial gastritis.
METHODS: A total of 32 patients with chronic superficial gastritis were composed of 20 cases of piwei damp-heat syndrome and 12 of pi-qi deficiency syndrome, while 10 cases of healthy people were taken as control. The mucosa of upper stomach was obtained by gastroscopic biopsy. The mucosal inflammation was observed and the protein expression of AQP4 was semiquantitated by the immunohistochemistry and image assay system.
RESULTS: The mucosal inflammation of piwei damp-heat syndrome group was more severe than that of the other two groups significantly (moderate or severe rate 17/20 vs 6/12, 0/10, P < 0.05, P < 0.01, respectively), and the protein expression of AQP4 in piwei damp-heat syndrome group was also higher than that of the other two groups significantly (209±59 vs 127±61 and 164±32, P < 0.01, P < 0.05, respectively).
CONCLUSION: AQP has a close connection with water metabolism. The abnormal expression of AQP may be one of the pathogenesis of piwei damp-heat syndrome.
