RESUMO
Objective:To explore the effect of coronary injection of recombinant human prourokinase (rhPro-UK) during PCI for ST-segment elevation acute myocardial infarction (STEMI) patients.Methods:A total of 124 STEMI patients treated in Tangshan Gongren Hospital, Hebei Province from November 2018 to November 2019 were selected as the research objects.They were simply randomized by random number table method into the observation group(63 cases) and the control group(61 cases). Thrombus aspiration was used.The control group was treated with 25 μg/kg tirofiban, and the observation group was injected with 20 mg rhPro-UK into the coronary arteries.After that, both groups underwent emergency PCI treatment.The bleeding degree, myocardial microcirculation indexes, plasma fibrinolytic factor changes, vascular recanalization, ST segment fall of electrocardiogram and changes in left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular ejection fraction (LVEF), cardiac index (CI) were recorded.Results:The peak value of creatine kinase isoenzymes MB (CK-MB) (184.64±21.47) U/L and the peak time of CK-MB (14.32±2.02) h in the observation group were significantly lower than those in the control group((258.94±31.64) U/L, (16.58±2.09) h), the differences were statistically significant ( t=15.345 and 6.123, all P<0.001). After treatment, human tissue plasminogen activator (t-PA) (0.85±0.28) kU/L in the observation group was significantly higher than that in the control group (0.74±0.24) kU/L, human plasminogen activator inhibitor (PAI-1) (0.16±0.05) kU/L.compared with the control group (0.32±0.08) kU/L significantly decreased ( t=2.345, P=0.021; t=13.401, P<0.001); 77.78% (49/63) of the ST-segment complete fall in observation group was significantly higher than 54.10% (33/61) of the control group ( Z=7.758; P=0.005), and 4.76% (3/63) in the observation group without a fall in ST segment was significantly lower than 19.67% (12/61) of the control group ( Z=6.480; P=0.011). The LVEDD at 7 days, 14 days and the LVESD at 7 days and 14 days in the observation group were (49.37±3.14) mm, (48.34±3.03) mm, (33.19±2.23) mm and (32.05±2.23) mm respectively, which were significantly lower than those in the control group at 7 days, (50.64±3.03) mm, (49.66±2.83) mm, (34.86±1.73) mm and 14 days, (33.74±1.97) mm respectively ( P<0.05 or P<0.001). The LVEF of 7 days and 14 days after treatment were (56.32±4.97)% and (59.23±5.11)%, which were significantly higher than those of the control group (54.46±4.87)% and (57.18±4.33)% ( P<0.05 or P<0.001). CI at 7 days and 14 days after treatment were (3.65±0.22) L/ (min·m 2) and (3.76±0.21) L/(min·m 2), which were significantly higher than those of the control group (3.48±0.25) L/(min·m 2) and (3.56±0.24) L/(min·m 2)( P<0.05 or P<0.001). Conclusion:STEMI patients treated by intraoperative coronary injection of Rhpro-UK versus tirofeban, can further improve the total bleeding rate and the vascular recanalculation rate, and also significantly improve plasma fibrinolysis factor, myocardial microcirculation and cardiac function.This provides an alternative to the treatment of myocardial infarction in patients with STEMI.
RESUMO
Objective To study the relationship between facial skin conditions and TCM constitutional types; To provide new means and methods for guidance of skin conservation and skin health improvement from the aspect of constitutional types. Methods Totally 2241 female volunteers in nine provincial capital cities and municipalities participated in this research, and were investigated by web questionnaire. Constitutional types were determined according to the“Classification and Judgment of TCM Constitutional Types”standard issued by China Association of Chinese Medicine. Skin color, glossiness, delicate degree, moistness, firmness, resilience, uniformity and other indicators were scored. Skin conditions were classified into three groups:1-3 score group, 4-6 score group, and 7-9 score group, and the constitutional differences among each group were compared. Results Yang-deficiency and mild constitutional types accounted for the largest proportion. Yellowish skin color accounted for the largest proportion, and the next were white, dark and reddish. Yang-deficiency constitutional type accounted for the largest proportion in 1-3 score group, and the second was Qi-stagnation; Yang-deficiency and mild constitutional types accounted for the largest proportion in 4-6 score group; mild constitutional type accounted for the largest proportion in 7-9 score group. Conclusion People with mild constitutional type got highest score in every skin index, while biased constitutional types influenced the score in varied degrees. The constitutional types which influenced Chinese urban females’ facial skin index more were Yang-deficiency and Qi-stagnation constitutional types.
