Objective: To study the correlations between galectin-3, soluble ST2 (sST2) levels and chronic heart failure (CHF) classiifcation, traditional HF indicator and short-term death in relevant patients. Methods: This research included 2 groups: CHF group, containing 142 relevant patients treated in our hospital from 2014-02 to 2015-10 and Control group, containing 85 normal subjects from physical examination at the same period of time. Based on NYHA criterion, the patients were classiifed in NYHA grade II, III and IV respectively. Blood levels of N-terminal brain natriuretic peptide (NT-ProBNP), high-sensitivity C reactive protein (hs-CRP) and ultrasonic morphology were examined upon admission; protein expressions of galectin-3 and sST2 were assessed by ELISA. Results: The patients with NYHA grade III and IV had increased levels of galectin-3 and soluble sST2; galectin-3, sST2 were positively related to NT-ProBNP, hs-CRP and LVEDD, while negatively related to LVEF. Logistic regression analysis indicated that galectin-3 and sST2 were related to short-term death in CHF patients,P<0.05. Area under ROC curve of galectin-3 and sST2 for diagnosing CHF were 0.738 and 0.771,P<0.01. Conclusion: Galectin-3 and sST2 levels were related to traditional HF indicator and could be used for CHF diagnosis in relevant patients.

Objective To investigate the relationship between interleukin 1β( IL?1β) , interleukin?33 ( IL?33) , neutrophil?to?lymphocyte ratio ( NLR ) and atrial fibrillation. Methods Eighty?two patients with nonvalvular atrial fibrillation treated in the department of cardiology in the Fourth People′s Hospital of Jinan from October 2015 to October 2016 were enrolled in the study,including 43 patients with persistent atrial fibrillation and 39 patients with paroxysmal atrial fibrillation. 50 healthy subjects were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was used to determine the concentration of IL?1βand IL?33,and the left atrial diameter ( LAD) was measured by echocardiography. Results ( 1) The concentrations of IL?1β,NLR and LAD in the paroxysmal atrial fibrillation group were (24. 44±4. 89) ng/L,(2. 51±1. 22) %,(36. 16± 6. 12) mm,the concentrations of IL?1β,NLR and LAD in the persistent atrial fibrillation group were (26. 95±5. 86) ng/L,(5. 7±1. 8) %,(39. 36±4. 78) mm and the values in the control group were (19. 53±4. 51) ng/L,(1. 82 ± 0. 41 ) %, ( 33. 31 ± 2. 89 ) mm, respectively. The differences among the three groups were statistically significant ( F=16. 74,11. 82,14. 85,P<0. 01) . The indexes of paroxysmal atrial fibrillation group and persistent atrial fibrillation group were higher than those of the control group ( P<0. 01 ) . ( 2 ) In the persistent atrial fibrillation group, NLR and LAD were ( 5. 7 ± 1. 8 )% , and ( 39. 36 ± 4. 78 ) mm, higher than those of the paroxysmal atrial fibrillation group ( (2. 51±1. 22)%,(36. 16±6. 12) mm),the differences were statistically significant ( P<0. 01) . However,the level of IL?1βin the persistent atrial fibrillation group was not significantly different from that in the paroxysmal atrial fibrillation group ( (26. 95±5. 86) ng/L vs. (24. 44±4. 89) ng/L,P>0. 05). (3) The concentrations of IL?33 in the paroxysmal atrial fibrillation group,atrial fibrillation group, control group were ( 48. 31 ± 4. 72 ) ng/L, ( 50. 03 ± 2. 18 ) ng/L, ( 56. 87 ± 5. 12 ) ng/L, respectively. The difference among the three groups has no statistical significance ( F=2. 52, P>0. 05 ) . ( 4 ) NLR level was positively correlated with LAD ( r=0. 32,P=0. 002) . There was no significant correlation among IL?1β,IL?33 and LAD ( r=0. 16, P=0. 11, r=0. 02, P=0. 37 ) . Conclusion The levels of IL?1β, NLR and LAD in peripheral blood of patients with atrial fibrillation were significantly higher than those in patients with sinus rhythm,and there was a positive correlation between NLR and LAD.

From August 2011 to March 2012,5 241 type 2 diabetic patients with body mass index ≥ 24kg/m2 were enrolled from 60 hospitals in Guangdong Province.According to estimated glomerular filtration rate (eGFR),a total of 2 631 subjects with norml urine microalbumin level (<30 ng/L) were divided into normal eGRF group and decreased eGRF group.Binary logistic regression was used to analyze the associations between eGFR and its related risk factors.The results showed that age,blood uric acid,blood urea nitrogen,history of hypertension and coronary heart disease,family history of diabetes,and hyperuricemia were positively related to lowering of eGFR (P< 0.05 or P<0.01).HbA1C<7%,regular glucose monitoring,and regular physical activity were negatively related to eGFR decrease (all P< 0.01).These results suggest that urine microalbumin and eGFR should be applied to overweight or obese patients with type 2 diabetes in order to screen diabetic nephropathy.Furthermore,intensive control of blood glucose,uric acid,and blood pressure is beneficial to lowering the risk of diabetic nephropathy.

Objective To understand the coronary characteristic of acute coronary syndrome patients with ischemic J wave. Methods Comparison was made between 60 acute coronary syndrome patients with ischemic J wave and 60 acute coronary syndrome patients without ischemic J wave. All patients were examined by Holter monitoring electrocardiogram and coronary arteriongraphy. To distinguish the stenosis degree was defined in three degree based on Genisini score of 0, 1-80, and 81-160. Plaque types were divided into Ⅰ,Ⅱ, Ⅲ by Ambrose classification,the coronary and plaque characteristics of acute coronary patients were observed with ischemic J wave. Results There were no significant difference of stenosis degree between the two groups ( U = 3. 0686, P = 0. 0022), whereas there were significant difference of plaque types (x2 =16. 0890, P = 0. 0003) and coronary vessel numbers(x2 =12. 1045, P = 0. 0024). The degree of stenosis, the plaque types, and number of stent in coronary vessel were positively correlated with ischemic J wave(r =0. 44,0. 34,0. 31 ;P <0. 05). Conclusions The acute coronary syndrome with ischemic J wave patients is often not only accompanied with serious coronary stenosis and high incidence rate of multivessel disease,but also high probability of unstabilized plaque. Ischemic J wave can be a predictor of super-acute ischemic of myocardium.

Objective:To analyze the clinical characteristics of patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR), and to explore the risk factors leading to poor prognosis.Methods:The clinical data of 95 patients with ECPR admitted to the First Affiliated Hospital of Zhengzhou University from January 2020 to May 2023 were retrospectively analyzed. According to the survival status at the time of discharge, the patients were divided into the survival group and death group. The difference of clinical data between the two groups was compared to explore the risk factors related to death and poor prognosis. Risk factors associated with death were identified by Binary Logistic regression analysis. Results:A total of 95 patients with ECPR were included in this study, 62 (65.3%) died and 33 (34.7%) survived at discharge. Patients in the death group had longer low blood flow time [40 (30, 52.5) min vs. 30 (24.5, 40) min ] and total cardiac arrest time[40 (30, 52.5) min vs. 30(24.5, 40) min], shorter total hospital stay [3 (2, 7.25) d vs. 19 (13.5, 31) d] and extracorporeal membrane oxygenation (ECMO) assisted time [26.5 (17, 50) h vs. 62 (44, 80.5) h], and more IHCA patients (56.5% vs. 33.3%) and less had spontaneous rhythm recovery before ECMO (37.1% vs. 84.8%). Initial lactate value [(14.008 ± 5.188) mmol/L vs.(11.23 ± 4.718) mmol/L], APACHEⅡ score [(30.10 ± 7.45) vs. (25.88 ± 7.68)] and SOFA score [12 (10.75, 16) vs. 10 (9.5, 13)] were higher ( P< 0.05). Conclusions:No spontaneous rhythm recovery before ECMO, high initial lactic acid and high SOFA score are independent risk factors for poor prognosis in ECPR patients.

OBJECTIVETo study the effect of Mps1 on BRAFWT/MEK/ERK pathway in the presence of wild type BRAF or BRAFV600E in melanoma.
METHODSMelanoma cells harboring BRAFWT genotype were transfected either with pBabe-puro-GST-BRAF-WT and/or pBabe-puro-GFP-Mps1-WT or pBabe-puro-GST-BRAFV600E and/or pBabe-puro-GFP-Mps1-WT, followed by Western blot to detect Mps1 and p-ERK expression. The melanoma cells harboring BRAFWT and BRAFV600E genotype were infected with pSUPER-Mps1 retrovirus to knockdown the endogenous Mps1 protein, followed by Western blot to detect Mps1 and p-ERK expression. Meanwhile, melanoma cells harboring BRAFV600E genotype were infected with pBabe-puro-GFP-Mps1 and Western blot was performed to detect Mps1 and p-ERK expression.
RESULTSIn melanoma cells harboring BRAFWT genotype and transfected with pBabe-puro-GST-BRAF-WT and pBabe-puro-GFP-Mps1-WT, phospho-ERK levels were notably reduced as compared to either negative control or empty vector. However, cells transfected with pBabe-puro-GST-BRAFV600E and pBabe-puro-GFP-Mps1-WT, phospho-ERK levels did not change significantly compared with either negative control or empty vector. Knockout of Mps1 in BRAF wild-type cell lines led to an increased ERK activity. However, there was no significant change of ERK activity in BRAFV600E cell lines in the absence of Mps1. The expression of p-ERK in BRAFV600E mutant cell lines infected with pBabe-puro-GFP-Mps1-WT did not show any significant difference from either negative control or empty vector.
CONCLUSIONSBased on these findings, it suggests that there exists an auto-regulatory negative feedback loop between the Mps1 kinase and BRAFWT/ERK signaling. Oncogenic BRAFV600E abrogates the regulatory negative feedback loop of Mps1 on the MAPK pathway.
