title: [Impacts of electroacupuncture on constipation of intestine and lung syndromes and its correlative study].
abstract: OBJECTIVE
  To observe the improvements in constipation differentiated as intestine system syndrome and lung system syndrome treated with electroacupuncture (EA) and explore their correlation.
  
  
  METHODS
  Seventy cases of severe functional constipation were randomized into an EA group and a pseudo-EA group, 35 cases in each one. In the EA group, the needles were inserted deeply at Tianshu (ST 25) and Fujie (SP 14) on bilateral sides, and directly went to parietal peritoneum. EA was attached to the needles, dense-disperse wave, 2 Hz/15 Hz, and 0.1 to 1.0 mA. The perpendicular insertion was done at Shangjuxu (ST 37), 25 mm in depth. After qi arrival, the needle was lifted, thrusted and rotated once every 10 min, for 3 times totally. The needles were retained for 30 min. In the pseudo-EA group, the pseudo-points lateral to Tianshu (ST 25), Fujie (SP 14) and Shangjuxu (ST 37) on bilateral sides were punctured shallowly. The electric stimulation was pretended to connect but with the electric wire cutting off. The needles were retained for 30 min. The treatment was given 5 times weekly in the first two weeks and 3 times weekly in the later 6 weeks. Totally, 28 treatments were required. TCM intestine and lung syndrome scale was used for evaluation. The changes in TCM syndromes were observed before and after treatment in the patients of the two groups.
  
  
  RESULTS
  The total score of intestine and lung syndrome and the score of individual syndrome were all reduced after treatment as compared with those before treatment in the two groups (both P<0.01). The improvements of the EA group in the total score of intestine system syndrome, the scores of large. intestine syndrome and stomach syndrome, the total score of lung system syndrome and the score of lung dysfunction in dispersing and descending syndrome were superior to those of the pseudo-EA group (P<0.01, P<0.05). The differences in the scores of lung qi deficiency syndrome and throat syndrome were not significant between the two groups (all P>0.05). Simultaneously, the very strong positive correlation (P<0.01) and positive linear correlation (P<0.01) were presented in the total score of intestine and lung syndrome of the two groups.
  
  
  CONCLUSIONS
  EA obviously improves in intestine system syndrome (including large intestine syndrome and stomach syndrome), as well as lung system syndrome (lung dysfunction in dispersing and descending) in the treatment of constipation. But the improvements are not apparent in the treatment of lung qi deficiency and throat disorder. Additionally, the obvious correlation is displayed in the improvements in intestine and lung syndrome.
