RESUMEN
Myocardial infarction (MI) has the characteristics of high mortality rate, strong suddenness and invisibility. There are problems such as the delayed diagnosis, misdiagnosis and missed diagnosis in clinical practice. Electrocardiogram (ECG) examination is the simplest and fastest way to diagnose MI. The research on MI intelligent auxiliary diagnosis based on ECG is of great significance. On the basis of the pathophysiological mechanism of MI and characteristic changes in ECG, feature point extraction and morphology recognition of ECG, along with intelligent auxiliary diagnosis method of MI based on machine learning and deep learning are all summarized. The models, datasets, the number of ECG, the number of leads, input modes, evaluation methods and effects of different methods are compared. Finally, future research directions and development trends are pointed out, including data enhancement of MI, feature points and dynamic features extraction of ECG, the generalization and clinical interpretability of models, which are expected to provide references for researchers in related fields of MI intelligent auxiliary diagnosis.

Objective:To explore the effect of post- abortion care service based on Wechat follow-up on contraceptive compliance of multiple induced abortion patients, and to evaluate the satisfaction with PAC service. Methods:A quasi-experimental method was adopted. A total of 300 cases of induced abortion were selected in Beijing Obstetrics and Gynecology Hospital affiliated to Capital Medical University from March 2018 to March 2019, with 150 cases from eastern branch in the experimental group and 150 cases from western branch in the control group. The control group received routine nursing care and post-abortion care service based on telephone follow-up, while the experimental group received routine nursing care and post-abortion care service based on Wechat follow-up. The missing rate of follow-up, the contraceptive method and the occurrence of unexpected pregnancy within one year after operation were collected in the two groups. Patients ′ follow-up compliance and nursing satisfaction were evaluated. Results:The awareness of the risk of induced abortion in the experimental group was 90.4% (120/135) higher than that in the control group 77.5% (88/111), and the difference was statistically significant ( χ 2 value was 9.128, P=0.010). The contraceptive consciousness of the two groups was 99.3% (134/135) and 94.6% (105/135), respectively, and the difference was not statistically significant ( χ 2 value was 3.256, P=0.071). There was a statistically significant difference in the missing rate of follow-up between the two groups in January, March, June, and December ( χ 2 value was 13.664, P=0.003). Compared with 19.8% (22/111) in the control group, 73.3% (99/135) patients in the study group chose high-efficiency contraception, the difference was statistically significant ( χ 2 value was 69.795, P<0.01).There were no recurring pregnancies in the experimental group within one year, compared with 6.3% (7/111) in the control group, the difference was statistically significant ( χ 2 value was 6.630, P=0.003). In the experimental group, the participation rate of the follow-up were (95.37±12.29)%, which were higher than that in the control group (90.77±16.49)%. The difference was statistically significant ( t value was 2.438, P<0.05). The overall satisfaction score of the experimental group was 26.55 ± 2.80, which was higher than that of the control group (23.66 ± 3.32). The difference was statistically significant ( t value was 7.285, P <0.01). Conclusion:Post-abortion care service based on Wechat follow-up could enhance patients ′ compliance and satisfaction, guide patients to choose the right contraceptive methods, reduce the rate of repeated abortion and promote female reproductive health.

RESUMEN
Objective@#To investigate the effect of knee-chest position on exhaust and defecation of gynecologic diseases patients after laparoscopic surgery.@*Methods@#This quasi-experiment trail was conducted between July 2016 to May 2017, in a birth control ward at an obstetrics and gynecology hospital in Beijing, China. The study included a total of 258 patients who had gynecological benign diseases and received gynecological laparoscopic surgery. Participants were recruited in the trail by using a convenient sampling method with 130 patients who received gynecological laparoscopic surgery from July 2016 to December 2016 in the experimental group (on the basis of routine care, patients preformed a knee-chest position intervention after 6 hours of the surgery) and 128 patients who received gynecologic laparoscopic surgery between January 2017 and May 2017 in the control group (patients received a routine care). The primary end point was the postoperative anal exhaust.@*Results@#The ambulation rate before post-operative ventilation of the experimental group was 21.5% (28/130) less than that of the control group (91.4%, 117/128). The difference was statistically significant (χ2=127.903, P<0.01). The incidence of abdominal distension after operation was 0, lower than that of the control group 7.0% (9/128), the difference was statistically significant (χ2=9.471, P<0.01). The postoperative exhaust time and defecation time of the experimental group was (8.17 ± 2.88) h,(27.86 ± 4.29) h, earlier than that of the control group, (21.24 ± 5.90) h,(38.69 ± 7.73) h, and the differences were statistically significant (t=22.580, 13.885, P<0.01).@*Conclusions@#Postoperative knee-chest position significantly improved the exhaust and defecation of patients with gynecological benign disease after laparoscopic surgery.
