Objective: To investigate the impact of acute myocardial infarction (AMI) concurrent acute kidney injury (AKI) on major adverse cardiac events (MACE) occurrence during hospitalization.
Methods: A total of 625 AMI patients treated in our hospital from 2011-01 to 2014-03 were retrospectively studied. According to AKI incidence, the patients were divided into 2 groups: AKI group,n=86 and Non-AKI group,n=539. Based on AKI network (AKIN) criteria, AKI group was further divided into 3 subgroups as AKI-I subgroup,n=45, AKI-II subgroup,n=27, AKI-III subgroup,n=14; based on renal function at admission, AKI group was divided into another set of 2 subgroups as Normal renal function subgroup [(eGFR≥90 ml/(min·1.73m2)],n=61 and Renal dysfunction subgroup [(eGFR<90/(min·1.73m2)],n=25. The incidence of MACE was compared among different groups and the risk factors for MACE occurrence in AMI patients during hospitalization were studied by multivariate Logistic regression analysis.
Results: The incidences of MACE in AKI group and Non-AKI group was (59.3% vs 16.9%),P<0.05; in Normal renal function subgroup and Renal dysfunction subgroup was (59% vs 60%),P>0.05. Multivariate Logistic regression analysis showed that AKI was the independent risk factor for MACE occurrence in AMI patients; elevated AKI stages were accompanied with the higher incidence of MACE accordingly, compared with AKI-I subgroup, the incidences of MACE in AKI-III subgroup and AKI-II subgroup were as (OR=1.68, 95% CI 1.14-1.69),P<0.05 and (OR=2.01, 95% CI 1.35-1.84), P<0.05 respectively.
Conclusion: AKI was closely related to MACE occurrence in AMI patients, effectively preventing AKI may improve the prognosis in relevant patients.

The functional experiment teaching is an inspection to students of their thinking methods and the operation abilities,and is also the summary and sublimation of this course theories teaching.To adapt to the demand for cultivation of the talented person by innovation education,we probe into the improvement of teaching methods of the functional design experiment,and practiced the new teaching system of "six processes"teaching methods such as speaking briefly,giving a demonstration,questioning,giving clue,study and discussion,evaluation,and push forward the biomedical science modes toward the development of "living creature-mental state-social medical science mode"direction.

Objective To explore the value of Doppler tissue imaging(DTI) in assessing the left ventricular diastolic function of patients with essential hypertension.Methods Twenty healthy person(group A),35 essential hypertension(EH) patients with normal left ventrecular mass index(LVMI,group B) and 30 EH patients with left ventricular hypertrophy(LVH,group C) were included.The mitral annular velocity in early diastole(Ea) and late diastole(Aa) were detected by DTI,meanwhile the mitral inflow velocity E and A were detected.Results The E,E/A,Ea,Ea/Aa of group B and group C were lower than those of group A(P0.05).The Ea,Ea/Aa of group C were lower than those of group B(P

Objective To approach the correlation of the left ventricular function in elderly patients with acute myocardial infarction (AMI) at low-risk factor. Methods Forty-five elderly patients hospitalized for AMI were registered, including 20 patients who were underwent emergency percutaneous coronary intervention (PCI) after the onset of AMI and 25 patients who received conservative non-invasive therapies. These 45 cases all received echocardiography(ECHO) examination in the 4th and 24th week after acute myocardial infarction. Results In the PCI group, end-diastolic volume index (EDVI) and end-systolic volume index (ESVI) had significant difference (P0.05) after therapy; WMSI was higher than PCI group (P

OBJECTIVE: To analyze the clinical manifestations of heart, liver and kidney damages in the early stage of COVID-19 to identify the indicators for these damages. METHODS: We analyzed the clinical features, underlying diseases, and indicators of infection in 12 patients with COVID-19 on the second day after their admission to our hospital between January 20 and February 20, 2020.The data including CK-MB, aTnI, BNP, heart rate, changes in ECG, LVEF (%), left ventricular general longitudinal strain (GLS, measured by color Doppler ultrasound) were collected.The changes of liver function biochemical indicators were dynamically reviewed.BUN, UCR, eGFR, Ccr, and UACR and the levels of MA, A1M, IGU, and TRU were recorded. RESULTS: The 12 patients included 2 severe cases, 8 common type cases, and 2 mild cases.Four of the patients presented with sinus tachycardia, ECG changes and abnormal GLS in spite of normal aTNI and LVEF; 1 patient had abnormal CKMB and BNP.On the first and third days following admission, the patients had normal ALT, AST and GGT levels.On day 7, hepatic function damage occurred in the severe cases, manifested by elevated ALT and AST levels.Abnormalities of eGFR, Ccr and UACR occurred in 8, 5 and 5 of the patients, respectively.Abnormal elevations of MA, A1M, IGU and TRU in urine protein were observed in 4, 4, 5, and 2 of the patients, respectively. CONCLUSIONS In patients with COVID-19, heart damage can be identified early by observing the GLS and new abnormalities on ECG in spite of normal aTNI and LVEF.Early liver injury is not obvious in these patients, but dynamic monitoring of the indicators of should be emplemented, especially in severe cases. In cases with normal CR and BUN, kidney damage can be detected early by calculating eGFR, Ccr and UACR and urine protein tests.
