OBJECTIVES: To explore the relationship between the Observer's Assessment of Alertness/Sedation (OAAS) score and the bispectral index (BIS) during propofol titration for general anesthesia induction and analyze the impact of BIS monitoring delay on anesthetic depth assessment. METHODS: This study was conducted among 90 patients (ASA class I-II) undergoing elective surgery under general anesthesia. For anesthesia induction, the patients received propofol titration at the rate of 0.5 mg·kg^-1·min^-1 till OAAS scores of 4, 3, 2, and 1 were reached. After achieving an OAAS score of 1, remifentanil (2 μg·kg⁻¹) and rocuronium (0.6 mg·kg⁻¹) were administered, and tracheal intubation was performed 2 min later. BIS values, mean arterial pressure (MAP), heart rate (HR), and propofol dosage at each OAAS score were recorded, and the correlation between OAAS scores and BIS values was analyzed. The diagnostic performance of BIS values for determining when the OAAS score reaches 1 was analyzed using ROC curve. RESULTS: All the patients successfully completed tracheal intubation. BIS values of the patients at each of the OAAS scores differed significantly (P<0.01), and the mean BIS value decreased by 4.08, 8.32, 5.43 and 5.24 as the OAAS score decreased from 5 to 4, from 4 to 3, from 3 to 2, and from 2 to 1, respectively. There was a significant correlation between the OAAS score and BIS values (ρ=0.775, P<0.001). The median BIS value for an OAAS score of 1 was 76, at which point 83.33% of the patients had BIS values exceeding 60. ROC curve analysis showed that for determining an OAAS score of 1, BIS value, at the optimal cutoff value of 84, had a sensitivity of 88.9%, a specificity of 73.3%, and an area under the curve of 0.842 (0.803-0.881). CONCLUSIONS OAAS score during induction of general anesthesia is strongly correlated with BIS value and is a highly sensitive and timely indicator to compensate for the delay in BIS monitoring.

Objective:To investigate the application value of advance care planning among patients with chronic heart failure, so as to provide reference for the clinical practice of advance care planning.Methods:A total of 62 chronic heart failure patients from October 2017 to November 2019 in Fuwai Central China Cardiovascular Hospital were assigned to control group and experimental group according to the enrolled time, with 31 cases in each group. The patients in the control group from October 2017 to October 2018 recieved routine nursing, the experimental group from November 2018 to November 2019 carried out advance care planning based on the routine care. Before and after 3 weeks of intervention, the fatigue symptom and psychological condition were assessed by the Multidimensional Fatigue Inventory (MFI-20) and Symptom Checklist 90 (SCL-90), respectively.Results:There was no significant difference in the score of MFI-20 and SCL-90 before intervention between the two groups( P>0.05). After 3 weeks of intervention, the mental fatigue scores and total scores in MFI-20 were (8.23 ± 2.77), (51.00 ± 5.03) points in the experimental group, significantly lower than those in the control group (10.23 ± 2.58), (54.06 ± 5.50) points, the differences were statistically significant ( t=2.94, 2.29, all P<0.05). After 3 weeks of intervention, the somatization, obsessive symptoms, depression, anxiety, hostility scores and total score of SCL-90 were (1.28 ± 0.14), (1.43 ± 0.09), (1.19 ± 0.12), (1.13 ± 0.08), (1.33 ± 0.07), (121.00 ± 3.68) points in the experimental group, significantly lower than those in the control group (1.82 ± 0.44), (1.73 ± 0.58), (1.69 ± 0.12), (1.78 ± 0.13), (1.39 ± 0.10), (144.69 ± 9.09) points, the differences were statistically significant ( t values were 2.76-23.06, all P<0.05). Conclusions:Advance care planning can effectively alleviate fatigue symptom and improve psychological condition of patients with chronic heart failure.

Objective:To investigate the effects of intervention mapping on cardiopulmonary function for patients with acute heart failure in compensatory period, so as to provide references for their early rehabilitation activities.Methods:A total of 90 patients with acute heart failure admitted to Fuwai Central China Cardiovascular Hospital from October 2018 to October 2019 were enrolled in the present study. They were divided into experimental group and control group according to draw-lots-method, with 45 cases in each group. The control group received the routine care and activity plan, while the experimental group implemented intervention mapping-based stage early rehabilitation program. The indicators included 6MWT, forced expiratory volume in one second (FEV 1), brain natriuretic peptide (BNP) as well as Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the intervention effects were compared between the two groups. Results:There were no significant differences in FEV 1, 6MWT, BNP and MLHFQ scores between the two groups at admission ( P>0.05). On discharge, FEV 1, 6MWT were (2.17±0.44) L, (273.09±55.80) m in the experimental group, significantly higher than (1.94 ± 0.39) L and (236.44 ± 50.99) m in the control group; the plasma BNP were (676.79 ± 78.75) ng/L in the experimental group, significantly lower than (736.05 ± 78.77) ng/L in the control group; in addition, the physical demention, emotional dimenson, other demension scores and total scores of MLHFQ in the experimental group were (65.39 ± 5.02), (67.56 ± 4.99), (66.05 ± 4.16) and (66.33 ± 2.63) points, significantly higher than (59.79 ± 5.94), (64.33 ± 5.93), (62.76 ± 4.47), (62.36 ± 2.98) points in the control group, the differences were statistically significant ( t values were 2.56-6.51, all P<0.05). Conclusions:Designing and implementing stage early rehabilitation program using intervention mapping can promote cardiopulmonary function and quality of life of patients with acute heart failure in compensatory period.

Objective:To explore the application effect of comprehensive support infiltration nursing in patients with acute myocardial infarction (AMI) undergoing ventricular septal rupture (VSR) closure.Methods:Using the convenient sampling method, a total of 60 AMI patients who underwent closure operation for VSR in Henan Provincial People's Hospital from February 2018 to June 2020 were selected as research objects. The patients were divided into the control group and the observation group by the random number table method, with 30 cases in each group. The patients in the control group were given routine nursing care, while patients in the observation group were given comprehensive supportive nursing care on this basis. The Symptom Checklist (SCL-90) score, perioperative treatment compliance score and nursing satisfaction score were compared between the two groups.Results:After intervention, SCL-90 scores of the observation group were lower than those of the control group and the perioperative treatment compliance and nursing satisfaction scores were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Comprehensive support infiltration nursing can improve the poor psychological state of patients with VSR closure after AMI and improve treatment compliance of patients and nursing satisfaction.

This study was conducted to elucidate the reproductive effect of NP on testis, epididymis and epididymal sperm in vivo. Adult male Sprague-Dawley rats were gavaged with NP at 0, 40, 100, or 250 mg/kg body weight (bw) on alternate days for 90 d. The results showed that oral administration of NP may damage the structure and function of testis, induce apoptosis and oxidative stress in epididymis or even have cytotoxic effects on epididymal sperm.
