Objective:To investugate the unique electrocardiogram (ECG) characteristics of fulminant myocarditis (FM) patients and provide important clues for the diagnosis of FM.Methods:This was a retrospective study. Patients diagnosed with acute myocarditis at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from February 2017 to April 2022 were enrolled and divided into fulminant myocarditis group (FM) and non-fulminant myocarditis group (NFM) according to clinical diagnosis. A total of 246 healthy people who underwent physical examination in the Health examination Center of Tongji Hospital at the same period were selected as the control group. The clinical data and ECG characteristics of the above 3 groups were analyzed and compared. Logistic regression model was used to analyze the influence of ECG parameters on left ventricular ejection fraction in FM patients. Receiver operating curves were constructed to evaluate the predictive value of different ECG parameters for FM.Results:A total of 180 patients were included in this study (FM group: n=123; NFM group: n=57), with an age of (35.0±16.2) years and 106 males (58.89%). Compared with NFM group, ECG was significantly abnormal in FM group, with a higher incidence of sinus tachycardia, ventricular tachycardia or ventricular fibrillation, escape rhythm, right bundle branch block, third degree atrioventricular block, ST-segment elevation, low voltage, prolonged QTc interval, and widened QRS wave in the FM group (all P<0.05). The ECG parameters showed that the amplitude of the full lead QRS wave in FM group was lower than that in NFM group ( P<0.01). The average heart rate and QTc interval of FM group were significantly higher than those of NFM and control groups (all P<0.05). Although ST-segment elevation had a higher incidence in the FM group, ECG parameters showed that except for leads Ⅲ and aVF, the ST segment levels in all leads in the FM group were lower than those in the control group (all P<0.05). There was a statistically significant difference in some ST segment changes between FM and NFM groups, while there was no statistical difference between the NFM and control groups. Multivariate regression analysis showed that widened QRS wave and increased heart rate were the influencing factors for left ventricular systolic dysfunction in FM patients ( OR=16.914, 95% CI: 1.367-209.224, P=0.028; OR=1.026, 95% CI: 1.010-1.042, P=0.001). Receiver operating curve analysis showed that heart rate>86.90 beat/min, QTc>431.50 ms, and RV5+SV1<1.72 mV had certain predictive value for FM diagnosis. Conclusions:FM patients displayed marked and severe ECG abnormalities, and characteristic changes in ECG can provide important first clues for the diagnosis of FM.

OBJECTIVES: This study aimed to analyze the application value of a modified tragus edge incision and transmasseteric anteroparotid approach to condyle reconstruction. METHODS: Condyle reconstruction was performed in 16 patients (9 females and 7 males) with modified tragus edge incision and transmasseteric anteroparotid approach. After regular follow-up, the function of condyle reconstruction was evaluated by clinical indicators, such as parotid salivary fistula, facial nerve function, mouth opening, occlusal relationship, and facial scar. The morphology of rib graft rib cartilage was evaluated by imaging indicators, such as panoramic radiography, CT, and three-dimensional CT image reconstruction. RESULTS: At 6-36 months postoperative follow-up, all patients had good recovery of facial appearance, concealed incisional scar, no parotid salivary fistula, good mouth opening, and occlusion. One case had temporary facial paralysis and recovered after treatment. Radiographic evaluation further showed that costochondral graft survived in normal anatomic locations. CONCLUSIONS The modified tragus edge incision and transmasseteric anteroparotid approach can effectively reduce parotid salivary fistula and facial nerve injury in condylar reconstruction. The surgical field was clearly exposed, and the incision scar was concealed without increasing the incidence of other complications. Thus, this approach is worthy of clinical promotion.

Objective: To evaluate the cardiovascular damage of patients with COVID-19, and determine the correlation of serum N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin-I (cTnI) with the severity of COVID-19, and the impact of concomitant cardiovascular disease on severity of COVID-19 was also evaluated. Methods: A cross-sectional study was designed on 150 consecutive patients with COVID-19 in the fever clinic of Tongji Hospital in Wuhan from January to February in 2020, including 126 mild cases and 24 cases in critical care. Both univariate and multivariate logistic regression were used to analyze the correlation of past medical history including hypertension, diabetes and coronary heart disease (CHD) , as well as the levels of serum NT-proBNP and cTnI to the disease severity of COVID-19 patients. Results: Age, hypersensitive C-reactive protein(hs-CRP) and serum creatinine levels of the patients were higher in critical care cases than in mild cases(all P<0.05). Prevalence of male, elevated NT-proBNP and cTnI, hypertension and coronary heart disease were significantly higher in critical cases care patients than in the mild cases(all P<0.05). Univariate logistic regression analysis showed that age, male, elevated NT-proBNP, elevated cTnI, elevated hs-CRP, elevated serum creatinine, hypertension, and CHD were significantly correlated with critical disease status(all P<0.05). Multivariate logistic regression analysis showed that elevated cTnI(OR=26.909, 95%CI 4.086-177.226, P=0.001) and CHD (OR=16.609, 95%CI 2.288-120.577, P=0.005) were the independent risk factors of critical disease status. Conclusions COVID-19 can significantly affect the heart function and lead to myocardial injury. The past medical history of CHD and increased level of cTnI are two independent determinants of clinical disease status in patients with COVID-19.

Objective To investigate the variation characteristics of peripheral platelet parameters in children with dengue fever and to assess their use and value in diagnosis,prognosis and treatment for dengue fever.Methods Platelet parameters of 69 pediatric patients with dengue fever in acute febrile phase and remission period and 103 healthy controls were compared.The difference of platelet parameters between the liver function injury group and the normal liver function group,the coagulation dysfunction group and the coagulation function normal group,the severe group and the mild group with dengue fever was compared,the causes of thrombocytopenia in children with dengue was investigated so as to better understand the situation of bone marrow producing platelets.Results P-LCR,PDW,MPV were significantly higher in patients in acute febrile phase of dengue fever,compared with the healthy subjects(P＜0.01),while PCT,PLT were significantly lower in patients in acute febrile phase of dengue fever,compared with the healthy subjects(P＜0.01).MPV was significantly lower in patients with abnormal hepatic function when compared with patients with normal hepatic function(P＜0.05),while other platelet parameters did not show significant differences(P＞0.05).PLT and PCT were significantly lower in the severe patients than those in the mild patients(P＜0.05),while other platelet parameters did not show significant differences(P＞0.05).Peripheral platelet parameters did not show significant differences between patients with or without abnormal coagulation function (P＞0.05).Conclusion Peripheral platelet parameters may play a role in the diagnosis,treatment and prognosis of dengue fever in children.

AIM:Mitochondrial DNA (mtDNA) copy number variation (CNV), which reflects the oxidant-induced cell damage, has been observed in a wide range of human diseases .However, whether it correlates with heart failure , which is closely related to oxidative stress, has never been elucidated before .We aimed to systematically investigate the association between leukocyte mtDNA CNV and heart failure risk and prognosis .METHODS: A total of 1 700 hospitalized patients with heart failure and 1 700 age-and gender-matched community population were consecutively enrolled in this observational study , as well as 1 638 ( 96.4%) patients were fol-lowed prospectively for a median of 17 months (12~24 months).The relative mtDNA copy number in leukocyte of peripheral blood or cardiac tissue was measured in triplicate by quantitative real-time PCR method .RESULTS:Patients with heart failure possessed much lower relative mtDNA copy number compared with control subjects (P<0.01), especially for the patients with ischemic etiology (P<0.01).Patients with lower mtDNA copy number exhibited 1.7 times higher risk of heart failure ( P<0.01).Long-term follow-up (median 17 months) showed that decreased mtDNA copy number was significant associated with both increased cardiovascular deaths (P<0.01) and cardiovascular rehospitalization (P<0.01).After adjusted for the conventional risk factors and medications , lower mtDNA copy number were still significantly associated with 50% higher cardiovascular mortality (P <0.05).CONCLUSION:
mtDNA copy number depletion is an independent risk factor for heart failure and predicted higher risk of cardiovascular deaths in patients with heart failure .

AIM:The 50-Hz magnetic field (MF) is a potential health-risk factor.Its effects on the cardiovascular system have not been fully investigated .This study was conducted to explore the effects of long-term exposure to 50-Hz MF on the cardiovascular system . METHODS:In the study , an exposure system was constructed and the distribution of 50-Hz MF was detected .Sixty-four Sprague-Dawley (SD) rats were exposed to 50-Hz MF at 100 μT for 24 weeks, 20 hours per day, while another 64 rats were sham exposed. During the exposure, blood pressure was measured every 4 weeks, and 24 weeks later, echocardiography, cardiac catheterisation and electrocardiography were performed .Moreover , heart and body weight were recorded , while haematoxylin-eosin staining and real-time PCR were conducted .RESULTS:The results showed that compared with the sham group , exposure to 50-Hz MF did not exert any effect on blood pressure, pulse rate, heart rate and cardiac rhythm.Further, echocardiography and cardiac catheterisation showed that there were no significant differences in the cardiac morphology and haemodynamics .In addition , histopathological examination showed that 50-Hz MF exposure had no effect on the structure of hearts .Finally, the expression of the cardiac hypertrophic relative genes did not show any significant differences between 50-Hz MF exposure group and the sham group .CONCLUSION: Taken together , in SD rats, exposure to 50-Hz/100-μT MF for 24 weeks did not show any obvious effects on the cardiovascular system .

BACKGROUND:Cytochrome P450 ( CYP) epoxygenases metabolize arachidonic acids ( AA) to form epoxyeicosatrienoic acids
(EETs), which exert beneficial roles in the treatment of cardiovascular diseases , but little is known about its role on adventitial remo-deling.METHODS:We used C57BL/6J mice in vivo and primary rat adventitial fibroblasts ( AFs) in vitro treated with angiotensin II (Ang II) to investigate the effects of CYP2J2 gene delivery and exogenous EETs administration on adventitial remodeling .RESULTS:CYP/sEH system was found to exist in human adventitia , and involved in adventitial remodeling process .Exogenous EETs administra-tion significantly inhibited Ang II-induced AFs activation , characterized by differentiation , proliferation, migration, and collagen syn-thesis.These protective effects were partially reversed by PPARγantagonist GW9662 pretreatment or SOCS3 siRNA transfection.EETs suppressed Ang II-induced IκBαphosphorylation , subsequent NF-κB nuclear translocation via PPARγdependent signaling pathway in AFs.Additionally, EETs reduced Ang II-induced JAK2, STAT3 phosphorylation and subsequent phosphor-STAT3 nuclear transloca-tion, which were mediated by SOCS3 induction but independent of PPARγactivation.Furthermore, rAAV-CYP2J2 gene delivery re-duced vessel wall thickening , AFs differentiation , proliferation and collagen deposition in aortic adventitia induced by Ang II infusion , which were mediated by NF-κB and SOCS3/JAK/STAT signaling pathways in blood pressure-dependent and -independent manners , re-spectively.CONCLUSION:We concluded that CYP2J2 overexpression attenuated Ang II-induced adventitial remodeling via PPARγ-dependent NF-κB and PPARγ-independent SOCS 3/JAK/STAT inflammatory signaling pathways .
