Objective: To observe effect of square dance exercises on symptom scores in menopausal women with coronary heart disease (CHD). Methods: A total of 39 menopausal CHD patients participated in square dance exercises, exercise intensity was 47.2%HRmax~58.1%HRmax(60~120 min/d), 5~7 times/week, three months, and they were regard as dance group. Control group consisted of 42 CHD women of same age living in the same district, who didn’t take part in exercise. After enrollment, these two groups received assessments of Seattle angina questionnaire (SAQ) and frequent physical and mental symptoms of menopausal women self-rating scale (Kupperman self-rating scale) within 3d and after three months. Results: There were no significant difference in score of each item and total score of SAQ in first assessment between two groups (P>0.05 all). Compared with first assessment and control group after three months, there were significant increase in scores of most items and total score of SAQ [(66.40±15.16) scores vs. (67.18±13.93) scores vs. (85.15±16.30) scores] in dance exercises group, P<0.01~0.05. There were no significant difference in score of each item and total score of Kupperman scale in first assessment between two groups (P>0.05 all). Compared with first assessment and control group after three months, there were significant decrease in scores of most items and total score of Kupperman scale [(29.40±6.51) scores vs. (29.73±6.26) scores vs. (23.65±6.29) scores] in dance exercises group, P<0.01~0.05. Conclusion: Square dance exercises may significantly decrease angina pectoris symptom and menopausal physical and mental symptoms in menopausal women with coronary heart disease.

Objective To investigate the effect of ulinastatin (UTI) on hepatic ischemia-reperfusion injury in rats. Methods Totally 24 adult Sprague-Dawley rats were randomly divided into 3 groups: sham-operated control group (SO group), ischemia-reperfusion group (I/R group) and ulinastatin group (UTI group). Liver in I/R group underwent 1 h of reperfasion after 30 min of ischemia. In UTI group, UTI (2×104 U/kg) was administered to rats 30 min before modeling. The levels of alanine aminotransferase, aspartate aminotransferase and tumor necrosis factor-alpha (TNF-α) in serum were measured and the levels of nitric oxide and malondialdehyde in liver were determined. The histological changes of liver were observed. Results The levels of alanine aminotransferase, aspartate aminotransferase and TNF-α in serum were significantly increased in I/R group compared with those in UTI group (P<0.05). The levels of nitric oxide and malondialdehyde in liver were significantly higher in I/R group than in UTI group (P<0.05).Histological examination of liver indicated that the damages were more severe in I/R group than in UTI group.Conclusion UTI has the ability to inhibit the production of TNF-α and oxyradical, and ameliorate microcirculatory dysfunction in rats with hepatic ischemia-reperfasion injury.
