OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Tianshu" (ST 25) on visceral pain and colonic mast cell (MCs) number and tryptase and SP expression in post-infectious irritable bowel syndrome (PI-IBS) rats, so as to reveal its mechanisms underlying improvement of PI-IBS. METHODS: Forty-five female Wistar rats were randomly divided into control, model and EA groups (15 rats/ group, 3 rats/group used for H. E. staining, and 12 rats/group for immunohistochemistry). The PI-IBS model was established by intra-anal injection of mixed liquor of 50% ethyl alcohol and trinitro-benzene-sulfonic acid (TNBS). EA (2 Hz/15 Hz, 0.5-1.0 mA) was applied to bilateral "Tianshu" (ST 25) for 30 min, once every day for 14 days. The visceral pain was measured by abdominal withdrawal reflex (AWR), for which the rectal implanted air balloon was dilated by infusion of normal saline. The histopathological changes of the colon tissue were observed after H. E. staining, and the colonic MCs were displayed by Toluidine blue staining. The expression of tryptase and SP proteins in the colon specimens were detected by immunohistochemistry. RESULTS: The AWR threshold was significantly lowered in the model group relevant to the control group (P<0.05) and considerably increased after EA intervention in comparison with the model group (P<0.05). The number of MCs and the expression levels of colonic tryptase and SP proteins in the colon tissues were significantly higher in the model group than in the control group (P<0.05), and obviously lower after EA intervention in the EA group than in the model group (P<0.05). CONCLUSION: EA of "Tianshu" (ST 25) can inhibit visceral pain in PI-IBS rats, which may be associated with its effects in activating MCs and down-regulating the expression of tryptase and SP proteins in the colonic tissues.

Objective To realize the myosin heavy chain(MHC) expression and related factors in severe pneumonia.Methods The staphylococcus aureus peumonia models of 30 Wistar rats were established and other 20 rats as control group.MHC expression and myocardial histopathologic score and cardiac function were examined.Results The expression of ?-MHC mRNA were lower in the rats with peumonia than that in the control group,while the expression of ?-MHC mRNA in the cases with peumonia increased significantly.The relative contents of ?-MHC mRNA had negative correlation with myocardial histopathologic score and had positive correlation with EF,FS.The relative contents of ?-MHC mRNA had positive correlation with myocardial histopathologic score and had negative correlation with EF,FS.Conclusions The cases with severe peumonia have abnormal expression of MHC,with the transformation of ?-MHC to(?-MHC).These proved that severe pneumonia can complicated with heart failure from gene level.

Objective To investigate the relationship between the matrix metalloproteinase-3(MMP-3)and the stability of carotid artery plaque,and explore MMP-3's prediction role on the attack and relapse of acute ischemic cerebrovascular events.Methods 100 patients with the first ever acute cerebral infarction,100 patients with chronic cerebral circulation insufficiency(CCCI)and 40 persons without cerebrovascular diseases were enrolled in this study.According to the carotid ultrasound examination,100 cerebral infarction patients were divided into three subgroup: unstable plaque group(45 patients,mixed plaque,soft plaque),stable plaque group(35 patients,plaque Group)and endometrial coarse group(25patients).Matrix metalloproteinase-3(MMP-3)levels of all the subjects were measured by enzyme-linked immunosorbent assay(as basal level).All the subjects were followed up for one year to observe cerebral infarction events.Serum MMP-3 levels of each group,and the basic serum MMP-3 levels were compared among patients who were attacked or relapsed cerebral ischemic with those who had not been attack cerebral ischemic during this period of time.Results 5 patients in the cerebral infarction group had relapse (5%),2 patients in the CCCI group were attacked by cerebral ischemic(2%),and no one in the normal control group was attacked by cerebral ischemic.Serum MMP-3 levels in the acute cerebral infarction group were significantly higher than CCCI group,and both groups were significantly higher than normal control group (P ＜0.05).The basic serum MMP-3 levels in all patients who were attacked by cerebral ischemic were significantly higher than those who had not been attack by cerebral ischemic during this period of time(P ＜0.05).The serum MMP-3 levels of the unstable plaque group were significantly higher than stable plaque group.And both groups were significantly higher than endometrial coarse group(P ＜0.05).Conclusions Elevated levels of matrix metalloproteinase-3(MMP-3)might have something with the stability of carotid atherosclerotic plaque,and participate the attack and the relapse of acute cerebral infarction.Determination of MMP-3 might be used to predict the attack and relapse of acute cerebral infarction.

Objective To evaluate the effectiveness of suberselective uterine arterial embolization for uterine fibroids.Methods Uterine arterial embolization with golyvimylalcohol(PVA) particles or Iodized oil and Gelfoam or Pingyangmycin lipiodol and Gelfoam was performed in 182 patients with uterine fibroids.Results Bilateral and unilateral superselective uterine arterial embolization were performed in 173 cases and 9 cases respectively. 6～28 months (mean 11 months) after the procedure, complete disappearance of tumor(16 cases), an average shinkage of 67% in tumor volume(152 cases) and a mean 42% reduction of uterine volume were obtained in 168 followed-up cases. The clinical symptoms were relieved significantly.The main side effets were hypogastic pain(135/182).Conclusion Superselection uterine arterial embolization is an effective and microinvasive method in treating uterine fibroids.
