Objective To investigate the diagnosis and prognosis value of plasma microRNA-30d (miR-30d)in acute coronary syndrome(ACS)patients.Methods It retrospectively recruited 170 cases of ACS patients from TEDA International Cardiovascular Hospital between September 2011 to February 2012, including 70 STEMI(male 54,female 16), 52 NSTEMI(male 34,female 18),48 UAP(male 29,female 19).At the same time,41 healthy controls(male 24,female 17)were enrolled into the study.Plasma miR-30d levels were determined by real-time quantitative PCR.In order to evaluate the dynamic change of miR-30d and other cardiac biomarkers,20 plasma samples of AMI patients were collected at 0-3 h,4-6 h,7-9 h, 10-12 h after pectoralgia.ROC curves and Kaplan-Meier survival curve were used to investigate clinical value of miR-30d in ACS.Results At 0-3 h after pectoralgia, miR-30d were significant higher in STEMI 7.208(0.170-11 070.735)and NSTEMI 7.989(0.836-151.391)than the controls 1.561(0.044-17.520)（Z1＝-5.792,Z2 ＝-6.113,P＜0.001）, but there were no statistic differences between UAP 1.073 （0.051-11.095）patients and the controls（Z＝-0.325,P＝0.745）.In 20 AMI patients,miR-30d levels peaked at 4-6 h and then dropped following 7-9 h, both earlier than cTnI, and the variation tendency was positive correlated with cTnI（r＝0.402,P＜0.01）.At 0-3 h after pectoralgia, the AUC, sensitivity and specificity of miR-30d for differentiating AMI and UAP were 0.882（95％ CI:0.830-0.935）,0.795（95％CI:0.711-0.861）and 0.854（95％ CI:0.716-0.935）respectively.When combined miR-30d and cTnI, the diagnostic AUC and specificity were 0.937（95％ CI: 0.902-0.972）and 0.937（95％ CI:0.818-0.984）,both enhanced when compared with miR-30d or cTnI alone.Kaplan-Meier survival curves revealed that there were no significant correlations between the miR-30d levels and MACE in both 30 days and 12 months（χ$lt@span sup=1$gt@2$lt@/span$gt@＝0.506,P＝0.477 and χ$lt@span sup=1$gt@2$lt@/span$gt@＝0.002, P＝0.963 respectively）.Conclusion Plasma miR-30d may be used as a potential biomarker for early diagnosis, but not prognosis in ACS patients.

Objective:To evaluate the effect of different doses of cisatracurium on the monitoring of motor-evoked potentials (MEPs) in the patients undergoing intracranial aneurysm clipping.Methods:Eighty patients of both sexes, aged 18-64 yr, with body mass index <30 kg/m 2, of American Society of Anesthesiologists physical statusⅠor Ⅱ, with Hunt-Hess grade 0-Ⅱ, undergoing intracranial aneurysm clipping under general anesthesia, were divided into 4 groups ( n=20 each) using a random number table method: conventional group (group R) and different doses of cis-atracurium groups (Cis 1-3 groups). After anesthesia induction, muscle relaxation was monitored, and train-of-four (TOF) stimulation (frequency 2 Hz, wave width 0.2 ms, interval 15 s) was applied to the ulnar nerve of forearm, and the TOF ratio was recorded as the baseline value (T 1). MEPs were assessed with a nerve electrophysiology monitor after induction of anesthesia.In Cis 1-3 groups, cis-atracurium 0.625, 0.833 and 1.000 μg·kg -1·min -1 were intravenously infused, while the equal volume of normal saline was given instead in group R when TOF ratio returned to the baseline value and MEPs could be effectively elicited.At T 1, immediately after dural incision (T 2), immediately after aneurysm occlusion (T 3) and immediately after dural closure (T 4), the TOF ratio, effective elicitation of intraoperative MEPs, and occurrence of intraoperative cardiovascular events, recovery of spontaneous breathing and body movement were recorded. Results:Compared with group R, no significant change was found in TOF ratio at each time point in group Cis 1 ( P>0.05), and TOF ratio was significantly decreased at T 2-4 in group Cis 2 and at T 2-4 in group Cis 3 ( P<0.05). Compared with group Cis 1, TOF ratio was significantly decreased at T 3, 4 in group Cis 2 and at T 2-4 in group Cis 3 ( P<0.05). The effective elicitation rate of MEPs was 100% in the four groups.There was no significant difference in the incidence of intraoperative cardiovascular events, recovery of spontaneous breathing and body movement among the four groups ( P>0.05). Conclusion:Continuous intravenous infusion of cis-atracurium 0.833-1.000 μg·kg -1·min -1 can maintain a certain degree of muscle relaxation without affecting MEP monitoring in the patients undergoing intracranial aneurysm clipping.

Objective: To determine the level of Soluble Suppression of Tumorigenicity-2 (sST2) in patients with heart failure(HF) and atrial fibrillation (AF), and to explore its diagnostic and prognostic value in patients with HF and AF. Methods: A prospective cohort study was carried out to investigate the data of 185 HF patients who were hospitalized between January 2018 and June 2018 in department of cardiology or department of cardiac care unit in TEDA International Cardiovascular Hospital. And according to whether they had atrial fibrillation before admission, we categorized patients into: HF with sinus rhythm (HF-SR, n=90) and HF with AF(HF-AF, n=95). Meanwhile, 40 healthy controls were collected. Baseline data of HF-SR and HF-AF groups and plasma sST2 levels in different ejection fraction groups were compared. Plasma sST2 level was determined by enzyme-linked immunosorbent assay(ELISA). Statistical methods such as nonparametric test and Spearman correlation analysis were used. The receiver operating characteristic curve was applied to evaluate the diagnostic value of sST2 in HF-SR and HF-AF groups. And by using the COX risk model, Multi-factor COX analysis was used to analyze the prognosis of patients. Results: Compared with healthy controls, the median (P₂₅, P₇₅) of Plasma sST2 levels in HF patients increased remarkably [32.93 (20.31-51.39) ng/mL vs 15.99(7.97-22.69) ng/mL, Z=-4.373, P<0.001]. Patients with HF-AF group had significantly higher test results [39.86 (27.20-59.21)] ng/mL than HF-SR group [24.74 (14.83-44.11)] ng/mL, Z=-6.783, P<0.001].In the HFmrEF and HFpEF subgroups, the plasma sST2 level of patients in the HF-AF group was higher than that in the HF-SR group (Z=-2.381, P=0.017; Z=-3.701, P<0.001).Spearman correlation analysis showed that, in HF-AF patients, plasma sST2 level was positively correlated with diastolic blood pressure, Hypertension, New York Association (NYHA) cardiac function classification Ⅲ to Ⅳ, white blood count(WBC), and the level of Alanine Aminotransferase (ALT), Υ-glutamine transaminase (Υ-GT), B-type natriuretic peptide (BNP) (r>0, P<0.05).Also, there is a negative correlation between sST2, left ventricular ejection fraction (LVEF) and estimated Glomerular Filtration Rate (eGFR) (r<0, P<0.05). At ROC analysis, sST2 showed predictive value in both HF-AF and HF-SR group, with an optimal cut-off value of 25.33 ng/mL(AUC 0.872, 95%CI: 0.805-0.935, P<0.001, sensitivity 81.1%, specificity 87.5%) and 23.34 ng/mL(AUC 0.665, 95%CI: 0.570-0.761, P<0.001, sensitivity 55.6%, specificity 77.5%).The AUC of BNP and sST2 in differential diagnosis of HF-SR and HF-AF was 0.604 and 0.699, respectively, and the AUC of sST2 was higher than that of BNP. Multi-factor COX analysis indicated that plasma sST2 level, BNP, NYHA cardiac function grading could be risk factors for cardiac events in HF patients. Plasma sST2, left atrial diameter (LA-D), and associated cardiomyopathy are risk factors for cardiac events in patients with HF-AF. The incidence of cardiac events in HF patients with sST2≥20.31 ng/mL was significantly higher than that of patients with sST2<20.31 ng/mL (χ²=7.625, P=0.006). The incidence of cardiac events in HF-AF patients with plasma sST2≥39.86 ng/mL was significantly higher than that in patients with sST2<39.86 ng/mL (χ²=4.287, P=0.038). Conclusions The plasma sST2 level in patients with HF-AF is significantly higher than that both in HF-SR and healthy controls. The diagnostic value of plasma sST2 in patients with HF-AF is higher than that in patients with HF-SR. It is suggested that sST2 are more valuable for the differential diagnosis of HF-SR, HF-AF than BNP. HF-AF Patients with plasma sST2 ≥ 39.86 ng/mL are prone to cardiovascular events.
