Objective To investigate the influences of different factors on postpartum pelvic floor muscle injury, and provide clinical evidence to the early prevention of pelvic floor dysfunction (PFD). Methods A total of 65 630 women, who participated the postpartum pelvic floor function screening in Tianjin, from December 2011 to December 2014 were selected in this study. The uniform detect methods was used in this study. The analysis based on the PFD was diagnosed by physi?cians of Women’s and Children’s Health Center in each district. The influences of different factors on postpartum pelvic floor muscle were analyzed. Results There were 19 452 (29.6%) women suffering from postpartum pelvic floor muscle inju?ry, with the abnormal rate 29.6%, which was higher in rural areas than that in urban areas (33.9%vs 27.8%). The abnormal rate was higher in women with junior middle education or below (34.1%) than that in women with senior middle or polytech?nic schooling (30.4%), and women with college or higher education (27.7%). There was a higher abnormal rate in women with vaginal surgery delivery (40.8%) than that in women with natural delivery (32.5%) and women with caesarean section (27.2%). The muscle abnormal rate was higher in women having given two or more than two times of deliveries (34.6% , 31.5%) than those having initial delivery (29.1%). Multiple factor analyses showed that city residency, higher education and less delivery times were protecting factors for postpartum pelvic floor muscle while vaginal surgery was a risk factor for post?partum pelvic floor muscle. Conclusion There is a high incidence of postpartum pelvic floor muscle injury in the region of Tianjin. Analyzing the risk factors and strengthening the management of pelvic floor muscle injury by early prevention or ear?ly treatment would help to reduce the incidence of PFD effectively during pre-pregnancy and perinatal periods.

OBJECTIVETo explore the prevalence, awareness, treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province, and to analyze risk factors of hypertension in this population.
METHODSA total of 984 (aged 18 and over) Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province were included with cluster sampling method from March to June, 2014. General information was obtained by questionnaire and blood pressure was measured. Multivariate logistic regression analysis was applied to analyze the risk factors of blood pressure.
RESULTSPrevalence of hypertension in this population was 19.3% (190/984), and standardized prevalence rate was 21.7%. The prevalence of hypertension were 16.3% (82/502), 21.0% (60/286) and 24.5% (48/196), and standardized prevalence rate was 17.8%, 22.1% and 26.6% among Tibetan monks aged 18-39, 40-59 and ≥60 years, respectively. Rates of awareness, treatment and control of hypertension in Tibetan monks were 9.5% (18/984), 4.2% (8/984)and 1.6% (3/984), respectively. Multivariate logistic regression analysis showed that age, body mass index and family history of hypertension were independent risk factors of hypertension in this population (P<0.01 or 0.05).
CONCLUSIONSPrevalence, awareness, treatment and control rates of hypertension among Tibetan monks in Gannan Tibetan Autonomous Prefecture of Gansu Province are relatively low. Age, body mass index and family history of hypertension are risk factors of hypertension in this population.

Objective:To reduce the occurrence of false alarm of vital signs during the use of ECG monitor by using stress ring to fix the lead wire of ECG monitor. Methods 200 patients who used ECG monitor in our department from March 2018 to February 2019 were intervened by two methods. The control group ( n=100) was connected and observed by routine method. The experimental group ( n=100) was added with lead wire to form "stress loop" on the basis of this method. Methods:The connection and fixation of ECG monitors were carried out. The differences of vital signs, heart rate/rhythm and respiratory false alarm between the two groups during ECG monitoring were compared, and the changes of nurses' workload, Hamilton anxiety score and satisfaction were compared.Results:There were significant differences in heart rate/rhythm and respiratory false alarm between the two groups ( P < 0.05). The scores of anxiety, nurses' workload and satisfaction in the experimental group were significantly improved. Conclusion:During the application of ECG monitor, the lead wire coiled into "stress ring" can effectively reduce the ECG monitor vital signs monitoring center rate/rhythm, respiratory false alarm phenomenon, reduce the workload of nurses, improve the satisfaction of nurses, and reduce anxiety of patients.
