RESUMEN
OBJECTIVE: To evaluate the accuracy of the YuWell YE660D oscillometric upper-arm blood pressure (BP) monitor in general population (for clinic and home BP measurements in adults) according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2â :â 2018) and its Amendment 1. 2020. METHODS: Subjects were recruited to fulfill the age, sex, BP and cuff distribution criteria of the AAMI/ESH/ISO Universal Standard in general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for arm circumferences 22-32â cm (standard) and 22-45â cm (wide range). RESULTS: Ninety-two subjects were recruited and 85 subjects were analyzed. For validation criterion 1, the meanâ ±â SD of the differences between the test device and reference BP readings was 0.3â ±â 7.2/2.2â ±â 5.5â mmHg (systolic/diastolic). For validation criterion 2, the SD of the averaged BP differences between the test device and reference BP per subject was 6.1/4.8â mmHg (systolic/diastolic). CONCLUSION: The YuWell YE660D oscillometric upper-arm electronic BP monitor has passed the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2â :â 2018) and its Amendment 1. 2020 in adults and hence can be recommended for home and clinical use.

OBJECTIVE: To evaluate the accuracy of the YuWell YE900 oscillometric upper-arm professional office blood pressure monitor in adults and children according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018). METHODS: Subjects were recruited to fulfill the age, sex, blood pressure and cuff distribution criteria of the AAMI/ESH/ISO Universal Standard in adults and children (aged 3-12 years) using the same arm sequential blood pressure measurement method. Three cuffs of the test device were used for arm circumference 18-22 cm (small), 22-32 cm (medium) and 32-42 cm (large). RESULTS: Ninety-two subjects were recruited, and 85 (50 adults and 35 children) were analyzed. For validation criterion 1, the mean ± SD of the differences between the test device and reference blood pressure readings was 1.7 ± 6.62/3.1 ± 5.76 mmHg (systolic/diastolic). For validation criterion 2, the SD of the averaged blood pressure differences between the test device and reference blood pressure per subject was 5.25/5.13 mmHg (systolic/diastolic). CONCLUSION: The YuWell YE900 professional electronic blood pressure monitor has passed the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) in adults and children and can be recommended for clinical use.

OBJECTIVE: To observe the therapeutic effect of Shenmai Injection (SI) in treating congestive heart failure (CHF). METHODS: The changes in cAMP, cGMP, serum cardiac troponin T (cTnT, a specific marker reflecting myocardial injury), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) were simultaneously monitored in 62 chronic CHF patients, distributed in the two groups, the routine treatment group and the routine treatment + SI group, by randomized grouping method, and the therapeutic effect of the two groups was compared. RESULTS: The plasma cAMP/cGMP ratio increased in early stage and decreased in late stage of the course of CHF. The serum cTnT level was progressively increased along with heart function deterioration. After treated with SI for 2 weeks, the CHF patients' hemodynamics got stable and heart function obviously improved. No serious adverse reaction was found in the therapeutic course. CONCLUSION: The level of serum cTnT might be taken as a reliable biochemical parameter to predict the prognosis of CHF patients. SI is an effective and safe agent in treating CHF.
