Objective:To explore the value of cardiodynamicsgram (CDG) obtained from electrocardiogram (ECG) data by radial basis functionradial basis function (RBF) neural network in early diagnosis of patients with acute coronary syndrome (ACS).Methods:Retrospective analysis method was used. Patients with chest pain as the main initial symptom in the emergency department of Baoan District People's Hospital of Shenzhen from October 2021 to September 2022 were enrolled. Baseline data were collected, including gender, age, smoking history, family history of coronary heart disease and history of hypertension, diabetes, hyperlipidemia, and atherosclerosis. The first 12-lead ECG was recorded after admission to the emergency department, and electrocardiodynamics analysis was performed to generate CDG. Receiver operator characteristic curve (ROC curve) was plotted to analyze the value of CDG and ECG in the early diagnosis of ACS and non-ST segment elevation ACS (NSTE-ACS). Sensitivity, specificity, area under the ROC curve (AUC), and 95% confidence interval (95% CI) were calculated. CDG and coronary angiography results of 3 patients with ACS with normal ECG were observed and analyzed. Non-ACS patients with normal ECG but positive CDG were followed for 30 days for adverse cardiovascular events. Results:A total of 384 patients with chest pain were included, including 169 patients with ACS and 215 patients without ACS. The proportion of male (87.0% vs. 53.0%), smoking history (37.9% vs. 12.1%), hypertension (46.2% vs. 22.3%), diabetes (24.3% vs. 7.9%), hyperlipidemia (55.0% vs. 14.0%) and history of atherosclerosis (22.5% vs. 2.3%) in ACS group were significantly higher than those in non-ACS group (all P < 0.05). The ROC curve showed that the AUC of CDG diagnosis of ACS was higher than that of ECG [AUC (95% CI): 0.88 (0.66-0.76) vs. 0.71 (0.84-0.92)], the sensitivity was 92.8%, 78.6%, and the specificity was 83.3%, 64.2%, respectively. The AUC of CDG diagnosis of NSTE-ACS was higher than that of ECG [AUC (95% CI): 0.85 (0.80-0.90) vs. 0.63 (0.56-0.69)], the sensitivity was 87.1%, 61.3%, and the specificity was 83.3%, 64.2%, respectively. CDG of 3 patients with ACS with normal ECG showed disordered state, and coronary angiography showed ≥70% stenosis of major coronary branches. Of 215 non-ACS patients, 20 had a normal ECG but positive CDG, and 3 developed ST segment elevation myocardial infarction (STEMI) within 30 days, and 2 developed unstable angina (UA) within 30 days. Conclusion:CDG has high value in early diagnosis of ACS patients and is expected to become an important means of early diagnosis of ACS in emergency.

Objective:To evaluate the clinical efficacy of hyperbaric oxygen as adjunctive therapy for neurological tinnitus (NT).Methods:Relevant clinical studies in eight databases (PubMed, Embase, Cochrane library, Web of Science, CBM, Cqvip, Wanfang data, and CNKI) were systematically searched, and data from the relevant studies were extracted based on inclusion and exclusion criteria. The methodological quality assessment of the data was conducted by using the Cochrane Collaboration’s tool for assessing risk of bias, the data analysis was conducted by using RevMan 5.3, and the sensitivity analysis of publication bias detection was conducted by using Stata 15.Results:A total of 12 randomized controlled trials (RCTs) were included. The results of meta-analysis showed that hyperbaric oxygen therapy had sound clinical efficacy in treating NT [ OR=4.10, 95% CI (2.81, 5.98), P<0.01]. It also reduced the scores of tinnitus severity index [ WMD=11.38, 95% CI (10.53, 12.23), P<0.01]. There was obvious asymmetry in the funnel diagram, and Egger’s test results ( t=2.96, P<0.05) indicated publication bias. Conclusion:Hyperbaric oxygen as adjunctive therapy for neurological tinnitus can effectively reduce tinnitus severity, which is superior to conventional treatment alone.
