Objective:To compare the accuracy and timeliness of 3-lead electrocardiography (ECG) and pulse oximetry (POX) in neonatal heart rate (HR) monitoring after birth.Methods:This prospective study recruited 42 high-risk newborns with gestational age ≥37 weeks and birth weight >1 500 g who were born through cesarean section without resuscitation requirement in Xi'an People's Hospital (Xi'an Fourth Hospital) from October 2019 to August 2020. 3-lead ECG electrodes and POX sensors were attached to the neonates immediately after drying to continuously monitor the HR within 10 min after birth. All procedure was recorded by video camera, and data were independently analyzed by a clinician after the procedure was completed. Differences in time required to connect the devices, time to obtain a reliable HR and the interval between them, the time needed for obtaining a reliable HR after birth, the proportion of neonates with reliable HR obtained within 5 min after birth and the consistency in the reliable HR readings between the two devices were compared using Wilcoxon signed-rank test, McNemar test, Spearman's correlation coefficient, intraclass correlation coefficient or Bland-Altman bias analysis.Results:The median time required to connect POX and 3-lead ECG and to acquire a reliable HR were 13.0 s (10.0-17.0 s) vs 23.0 s (18.0-28.3 s) ( Z=-5.050, P<0.001), and 79.5 s (56.2-128.0 s) vs 11.0 s (10.0-13.3 s) ( Z=-5.646, P<0.001), respectively. The total time from the beginning of connecting the devices and birth to acquiring a reliable HR were both longer for POX than those for 3-lead ECG [92.0 s (71.3-139.0 s) vs 35.0 s (30.0-39.5 s), Z=-5.579, P<0.001; 110.5 s (85.8-153.5 s) vs 52.0 s (45.0-66.3 s), Z=-5.579, P<0.001]. Reliable HRs were obtained in 69.1% (29/42) and 2.4% (1/42) of the infants by 3-lead ECG and POX within 1 min after birth, respectively. The percentage of infants for obtaining a reliable HR detected by 3-lead ECG within 5 min after birth were more than those by POX, but with statistically significant differences only at the first 60 s, 90 s, 120 s and 150 s (all P<0.001). The median HRs obtained by 3-lead ECG and POX within 10 min after birth were 161 beats/min (147-175 beats/min) and 160 beats/min (146-176 beats/min), respectively ( r=0.966, P<0.001). The mean difference of HR detected by the two devices was 0.56 beats/min (95% CI:-4.3 to 5.4 beats/min). The intraclass correlation coefficient was 0.961, showing good internal consistency. Conclusions:Neonatal HR can be assessed accurately by 3-lead ECG within 1 min after birth, which is far earlier than that by POX. Therefore, 3-lead ECG can be an option for continuously HR monitor in neonatal resuscitation.

Objective To explore the clinical application of indocyanine green (ICG) fluorescence imaging in patients with hepatocellular carcinoma.Methods 65 hepatocellular carcinoma patients,all were with single lesion,were divided into two groups:preoperative ICG administration group (n =28) and intraoperative ICG administration group (n =37).In preoperative ICG administration group ICG was given 2 to 14 days before surgery,while in the intraoperative ICG administration group it was given during surgery.ICG mediated near-infrared imaging system was used to observe the tumor and determine surgical margin.Results In the preoperative group,tumors were bright fluorescent imaging,in 6 cases 10 new small lesions were found,with cancer diagnosed in 4 patients,cirrhotic liver nodule in 5 patients,fatty degeneration in 1 patient.In the intraoperative group,tumors were clearly demarcated shadow,12 new small lesions were found in 8 cases,with cancer being diagnosed in 5 patients,cirrhotic liver nodule in 4 patients,fatty degeneration in 2 patients,hemangioma in 1 patient.Conclusion Both methods can find small lesions,preoperative administration group was better in identifying the nature of the tumor,while the intraoperative administration group was more valuable in determining the boundaries of the tumor.

Objective:To study the predictive value of serum albumin (ALB) on the first day of life for early-onset sepsis (EOS) in very low birth weight infants (VLBWI).Methods:From January 2015 to December 2020, clinical data of VLBWI (gestational age < 34 weeks, birth weight < 1 500 g) born and hospitalized in our hospital were collected. Based on the serum ALB level at admission, the infants were assigned into high, moderate and low ALB groups. C-reactive protein (CRP) and procalcitonin (PCT) levels among different ALB groups were compared. The infants were also assigned into EOS and non-EOS groups according to the occurrence of EOS and perinatal complications were compared between the two groups. The relationship between EOS and ALB level was analyzed. The predictive value of serum ALB was studied using receiver operating characteristic (ROC) curve analysis.Results:A total of 183 infants were enrolled, including 62 in the high ALB group, 87 in the moderate ALB group and 34 in the low ALB group; and 36 in EOS group and 147 in non-EOS group. The incidence of maternal chorioamnionitis was significantly higher in EOS group than non-EOS group [33.3% (12/36) vs. 6.8% (10/147), P<0.001]. Serum CRP and PCT in the low and moderate ALB groups were significantly higher than the high ALB group ( P<0.05), and the low ALB group showed higher CRP and PCT than the moderate ALB group ( P<0.05). Compared with the non-EOS groups, ALB in the EOS group was significantly lower [24.9 (24.0, 28.5) g/L vs. 29.5 (27.4, 31.2) g/L, P<0.001] and the incidence of hypoproteinemia was significantly higher [52.8% vs.10.2%, P<0.001]. As ALB decreased, the incidence of EOS increased. The incidence of EOS was 55.9% in the low ALB group, 16.1% in the moderate ALB group and 4.8% in the high ALB group ( P<0.001). The sensitivity and specificity of ALB predicting EOS was 69.4% and 79.6%, respectively, with a cut-off value of 27.0 g/L. Conclusions:The VLBWI with maternal chorioamnionitis and serum albumin lower than 27.0 g/L on the first day of life have higher risk of EOS.

Objective: To analyze the association between body mass index (BMI) and coronary heart disease. Methods: The data for the present study were from the prospective cohort study of China Kadoorie Biobank (CKB) in Qingdao, a total of 33 355 participants aged 30-79 years were included in the study. Cox regression analyses were performed to evaluate the association between BMI and coronary heart disease. Results: During the follow-up for an average 9.2 years, a total of 2 712 cases of ischemic heart disease (IHD) and 420 cases of major coronary events (MCE) were found. Multivariate Cox regression analysis showed that, compared with participants with normal BMI, the participants who were overweight had a 41% and 87% higher risk of IHD and MCE, the adjusted HR were 1.41 (95%CI: 1.27-1.56) and 1.87 (95%CI: 1.43-2.44), respectively. The participants who were obesity had 91% and 143% higher risk of IHD and MCE, the adjusted HR were 1.91 (95%CI: 1.72-2.13) and 2.43 (95%CI: 1.82-3.24), respectively. Conclusion: Overweight and obesity might increase the risk for IHD and MCE.
