Hearing loss caused by cochlear damage is the main symptom of sudden deafness (SD). Some patients also suffer from vestibular symptoms. In recent years, more attention has been paid to the vestibular dysfunction in patients with SD. The lesions could involve the whole inner ear in SD patients with and without vertigo. Comprehensive evaluation of vestibular function may help us understand the extent of lesions in sudden deafness and analyze the pathogenesis of disease. A less involvement of inner ear lesion may indicate a better hearing recovery.

Objective To observe the effects of berberine on inflammatory factors, adipokines and fatty acid metabo-lism in 3T3-L1 adipocytes, and to investigate the molecular mechanism underlying berberine’s role of improving insulin re-sistance. Methods mRNA level of inflammatory molecules, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 cells were determined by quantitative real time polymerase chain reaction (qRT-PCR) after cells were treated with different concentrations of berberine (0, 5, 10, 20, 40μmol/L) for 24 hours and with 10μmol/L berberine at different du-rations (0,4,8,24,48 h). These factors mainly included interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), leptin, adipo-nectin, visfatin, fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), adipose triglyceride lipase (ATGL) and adipocyte fatty acid binding protein (AFABP). Results In 3T3-L1 adipocytes, transcription level of IL-6, TNF-α, leptin, FAS, AT-GL, AFABP reduced with addition of berberine dosage at 10~40μmol/L(P<0.05)while visfatin mRNA level increased(P<0.05)compared with the control group. No significant difference was found in expression of adiponectin(P>0.05). Tran-scription level of IL-6, TNF-α, leptin, AFABP, ATGL, FAS decreased with time after 10μmol/L berberine intervention (8-48 h) compared with the control group(P<0.05). On the other hand, visfatin mRNA level increased(P<0.05)compared with the control group. Adiponectin mRNA decreased only after cells were treated with berberine for 48 h(P<0.05). No sig-nificant difference was found transcription of ACC between each groups treated with berberine(P > 0.05). Conclusion mRNA level of inflammatory factors, adipokines, key enzymes and protein in fatty acid metabolism in 3T3-L1 adipocytes can be affected by berberine and this effect depend on its dose and time . This might be the mechanisms underlying berber- ine to improve insulin resistance.

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.
