Objectives:To understand the current situation of premenstrual syndrome (PMS) and type D personality in female college students,and to explore the relationship between them.Methods:Totally 856 female college students were assessed with the Premenstrual Syndrome Scale (PMSS,those with total score of 6 or higher as having PMS) and Type D Personality Scale 14 (DS-14,those negative emotion and social inhibition factor with total score of 10 or higher as having type D personality).Result:A total of 280 students were detected with PMS,and the rote was 32.7％.Totally 272 students were detected with the type D personality,and the rote was 31.8％.The total score of DS-14 and the score of 2 factors were higher in PMS group than in non-PMS group (Ps ＜0.001).The rate of PMS was lower in type D personality group than in non-type D personality group (11.76％ vs.25.34％,P ＜ 0.001).Conclusions:The occurrence of premenstrual syndrome may be related to the type D personality.The evaluation of personality characteristics should be taken into consideration when formulating the intervention program.

Objective: To study therapeutic effect of personalized aerobic exercise based on exercise load test assessment on heart function and psychological state in patients with acute myocardial infarction (AMI). Methods: According to random number table, a total of 80 AMI patients during recovery period were randomly and equally divided into routine treatment group (n=40, received routine drug therapy) and exercise group (n=40, received personalized aerobic exercise based on exercise load test assessment on the basis of routine treatment group). Serum levels of high-sensitivity cardiac troponin I (hs-cTnI) and creatine kinase isoenzyme MB (CK-MB), and left ventricular ejection fraction (LVEF), stroke volume (SV), left ventricular fractional shortening (LVFS), ventricular wall thickening rate (△T), motion amplitude of interventricular septum (AIS), and scores of self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were compared between two groups before and after 12-week intervention. Results: Compared with before intervention, there were significant reductions in serum levels of hs-cTnI and CK-MB, and scores of SAS and SDS; and significant rise in LVEF, SV, LVFS, △T and AIS in both groups after 12-week intervention (except LVEF of routine treatment group), P<0.05 or <0.01; compared with routine treatment group, there were significant reductions in serum levels of hs-cTnI [(9.31±1.04) ng/L vs. (5.89±0.72) ng/L] and CK-MB [(11.34±1.25) U/L vs. (8.41±1.01) U/L],in scores of SAS [(51.34±6.54) scores vs. (42.32±5.29) scores] and SDS [(50.23±6.92) scores vs. (43.86±6.03) scores];and significant rise in LVEF [(57.12±6.67)% vs. (62.32±7.34)%], SV [(62.45±7.13) ml vs. (69.18±7.84) ml], LVFS [(23.93±2.96)% vs. (28.45±3.12)%], △T [(28.51±3.41)% vs. (34.52±4.87)%] and AIS [(9.56±1.02) mm vs. (12.45±1.46) mm] in exercise group, P<0.05 or <0.01. Conclusion: Personalized aerobic exercise based on exercise load test assessment can reduce myocardial cell injury, improve cardiac function, relieve negative emotions and promote patients’ rehabilitation rapidly.
