ABSTRACT

Objective:To investigate the preventive effects of intravenous N-acetylcysteine(NAC)administration on contrast-induced nephropathy(CIN)following coronary intervention in elder patients with coronary heart disease(CHD)complicated with moderate to severe renal dysfunction.Methods:In this retrospective study, 242 elderly patients with CHD and moderate to severe renal insufficiency hospitalized in the Department of Cardiology of the First Affiliated Hospital of Nanjing Medical University and undergone coronary angiography from January 2018 to February 2022 were included and divided into two groups: the treatment group(100 cases)receiving NAC plus a continuous intravenous drip of 0.9% sodium chloride solution before and after surgery and the control group(142 cases)treated with only a continuous intravenous drip of 0.9% sodium chloride solution.To ensure the comparability of important baseline data between the two groups, a 1∶1 propensity score matching analysis was used, and 70 patients in each group were finally included.Pre-and post-operative serum creatinine(Scr)and blood urea nitrogen(BUN)values were recorded, the endogenous creatinine clearance(Ccr)and estimated glomerular filtration rate(eGFR)were calculated, and the incidences of CIN and changes in renal function indicators were compared between the two groups.Results:After coronary intervention, the incidence of CIN in the treatment group was significantly lower than that in the control group(1/70 or 1.4% vs.8/70 or 11.4%, P=0.033). In the treatment group, Scr[(186.01±36.62)μmol/L vs.(195.84±36.39)μmol/L, t=4.957, P<0.001]and BUN[(13.97±2.89)mmol/L vs.(14.84±2.85)mmol/L, t=5.206, P<0.001]decreased, while Ccr[(31.84±6.54)ml/min vs.(30.08±5.65)ml/min, t=-5.076, P<0.001]and eGFR[(31.60±6.93)ml·min -1·1.73m -2vs.(29.82±5.92)ml·min -1·1.73m -2, t=-5.200, P<0.001]increased, compared with pre-operative levels.In the control group, Scr[(186.65±27.28)μmol/L vs.(182.53±22.08)μmol/L, t=-1.783, P=0.079]and BUN[(17.57±3.33)mmol/L vs.(17.13±3.35)mmol/L, t=-2.234, P=0.029]increased, but Ccr[(30.57±6.37)ml/min vs.(31.06±6.01)ml/min, t=1.435, P=0.156]and eGFR[(30.76±6.46)ml·min -1·1.73m -2vs.(31.26±6.02)ml·min -1·1.73m -2, t=1.436, P=0.156]decreased, compared with pre-operative levels, and there was no significant difference except BUN(all P>0.05). Conclusions:For elderly patients with coronary heart disease complicated with moderate to severe renal insufficiency, the use of NAC before and after coronary intervention can reduce the risk of CIN and help improve renal function.

ABSTRACT

Cardiovascular disease (CVD) remains the leading cause of death worldwide. Therefore, exploring the mechanism of CVDs and critical regulatory factors is of great significance for promoting heart repair, reversing cardiac remodeling, and reducing adverse cardiovascular events. Recently, significant progress has been made in understanding the function of protein kinases and their interactions with other regulatory proteins in myocardial biology. Protein kinases are positioned as critical regulators at the intersection of multiple signals and coordinate nearly every aspect of myocardial responses, regulating contractility, metabolism, transcription, and cellular death. Equally, reconstructing the disrupted protein kinases regulatory network will help reverse pathological progress and stimulate cardiac repair. This review summarizes recent researches concerning the function of protein kinases in CVDs, discusses their promising clinical applications, and explores potential targets for future treatments.

ABSTRACT

Objective To evaluate the diagnostic value of copeptin and cancer antigen 125 (Ca-125) in acute heart failure (AHF) patients with atrial fibrillation, and to explore the relationship between copeptin, Ca-125 and short-term cardiovascular events. Methods A total of 376 patients with acute left heart failure or permanent atrial fibrillation admitted to the Department of Cardiology of First Affiliated Hospital of Nanjing Medical University from January 2016 to January 2018 were enrolled as the study group. According to whether having atrial fibrillation or not, 376 patients were divided into atrial fibrillation group (n = 108), AHF group (n = 134) and AHF with atrial fibrillation group (n = 134). 102 healthy persons in the same period were enrolled as healthy control group. Copeptin, Ca-125, N-terminal pro-brain natriuretic peptide (NT-proBNP) within 24 hours after admission or on the day of physical examination were determined, and cardiac function indexes including left atrial diameter (LAD), left ventricular diameter (LVD) and left ventricular ejection fraction (LVEF) at 1 week after admission or on the day of physical examination were determined. Correlation analysis among above indexes was conducted by Pearson correlation analysis. Receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of copeptin and Ca-125 in AHF with atrial fibrillation. Results Compared with the healthy control group, copeptin, Ca-125, NT-proBNP, LAD, and LVD in atrial fibrillation group, AHF group and AHF with atrial fibrillation group showed a tendency of gradual increase [copeptin (pmol/L): 12.43±4.36, 18.77±5.29, 32.82±7.07 vs. 6.68±1.94; Ca-125 (kU/L): 18.82±7.39, 27.97±11.47, 61.37±25.49 vs. 4.43±1.74; NT-proBNP (ng/L): 1 070.87±428.84, 1 734.13±725.09, 2 745.92±709.91 vs. 570.40±213.87; LAD (mm): 37.24±6.35, 41.31±7.94, 46.24±10.96 vs. 33.29±4.53; LVD (mm): 49.46±5.19, 52.51±8.09, 55.96±6.49 vs. 45.99±6.26, all P < 0.05], and LVEF showed a tendency of gradual decrease (0.52±0.11, 0.46±0.10, 0.41±0.09 vs. 0.57±0.08, all P < 0.05), indicating that the deterioration of all indexes in AHF patients with atrial fibrillation was more obvious. Correlation analysis showed that copeptin was positively correlated with LAD (r = 0.479, P = 0.012) and LVD (r = 0.513, P = 0.005), and it was negatively correlated with LVEF (r = -0.626, P < 0.001). Ca-125 was positively correlated with LAD (r = 0.479, P = 0.011) and LVD (r = 0.513, P = 0.028), and it was negatively correlated with LVEF (r = -0.645, P = 0.019). ROC curve analysis showed that the area under ROC curve (AUC) of copeptin, Ca-125, NT-proBNP and copeptin combined with Ca-125 in the diagnosis of AHF with atrial fibrillation was 0.750, 0.623, 0.647 and 0.842, respectively, with diagnostic value on AHF with atrial fibrillation. The diagnostic value of copeptin combined with Ca-125 was the largest, with a sensitivity of 72.64% and a specificity of 92.47%. Compared with the healthy control group, the incidence of cardiovascular events after 3 months of follow-up in the atrial fibrillation group, AHF group and AHF with atrial fibrillation group was significantly increased [6.5% (7/108), 9.0% (12/134), 30.6% (41/134) vs. 1.0% (1/102), χ2 = 56.574, P = 0.000], indicating that patients with AHF and atrial fibrillation were more likely to have cardiovascular events. Copeptin combined with Ca-125 showed a significant positive correlation with short-term cardiovascular events (r = 0.641, P = 0.004). Conclusions The combination of copeptin and Ca-125 has a higher diagnostic accuracy for AHF patients with atrial fibrillation. Copeptin and Ca-125 were positively correlated with short-term cardiovascular events. It may be used to assess the prognosis of AHF patients with atrial fibrillation.

ABSTRACT

This study was aimed to detect the expression of miR-665 in the hippocampal of depression rat model treated with Kai-Xin Jie-Yu (KXJY) decoction and bioinformatic analysis of target genes of miR-665,in order to investigate the role of miR-665 in the pathogenesis of depression and the antidepressant mechanism of KXJY decoction.The rat model of chronic stress depression was established and then treated with KXJY decoction for 42 days.The total RNA from hippocampus tissues was extracted.And the relative expression of miR-665 in hippocampus of rats in each group was detected by RT-qPCR.TargetScan and microRNAorg databases were used to predict target genes for miR-665.DAVID database was used to classify GO function and to analyze KEGG signaling pathway of target genes.The results showed that compared with the normal group,the expression level of miR-665 in hippocampus of the model group was significantly higher with significant difference (P < 0.01).Compared with the model group,the expression level of miR-665 in hippocampus of Chinese medicine group and western medicine group decreased significantly with significant difference (P < 0.01).The biological functions of miR-665 target genes were mainly concentrated in the response to organic substance.The signal pathway was mainly concentrated in N-Glycan biosynthesis.It was concluded that miR-665 may be involved in the pathological process of depression,by correcting the abnormal expression of miR-665,which may be one of the antidepressant mechanisms of KXJY decoction.Through the analysis and prediction of the target genes,it provided a certain direction and theoretical basis for further study on the specific mechanism of KXJY decoction intervention on miR-665.

ABSTRACT

The neurovascular unit (NVU) is a dynamic functional module composed of neurons,microglia,blood-brain barrier (BBB) and the extracellular matrix that maintains the integrity of brain tissues.The chief members of NVU are one of the structural bases of the development of nervous system diseases.And they are involved in the pathological process of depression.The NVU instability of depression is characterized by the uncoupling of nerve and blood vessels,the increase of BBB permeability and the inflammatory response.Traditional Chinese medicine (TCM) has many advantages in the treatment of depression,and the effect of Kai-Xin Jie-Yu (KXJY) decoction in treating depression is remarkable.The purpose of this study was to explain the effect of KXJY decoction on NVU in terms of the functional connectivity of brain white matter,the protection of neurons and glial cells,the protection of vascular endothelial cells,the repair of BBB and the reduction of inflammation.It provided a new theoretical basis and method for the treatment of depression in TCM.

ABSTRACT

OBJECTIVE@#To investigate the effect of polymorphisms of NF-κB rs230521, NF-κB rs4648068 and pregnane X receptor (PXR) rs3814058 on platinum-based chemotherapy for non-small cell lung cancer patients. 
@*METHODS@#We collected 262 cases of non-small cell lung cancer patients, and then analyzed the genotypes of NF-κB and PXR by MassARRAY method. The impact of polymorphisms on efficacy, gastrointestinal toxicity and hematological toxicity was analyzed by logistic regression.
@*RESULTS@#Compared to patients with GG genotype, patients with NF-κB rs230521 CC genotype had the higher risk to suffer hematological toxicity (OR=3.485, P=0.011). Patients with PXR rs3814058 CC and CT genotype exhibited higher possibility to suffer hematological toxicity than those with TT (OR=2.045, P=0.048). Polymorphism of NF-κB rs4648068 did not show significant effect on chemotherapy efficacy and occurrence of gastrointestinal toxicity and hematological toxicity.
@*CONCLUSION@#Patients with NF-κB rs230521 CC, PXR rs3814058 CC and CT had higher risk to suffer hematological toxicity during platinum-based chemotherapy for non-small cell lung cancer. A rational dosage and course of treatment should be chosen to protect the patients with high risk genotype suffering hematological toxicity during their platinum-based therapy.

ABSTRACT

Objective To explore the curative effect of tirofiban treatment on high-risk acute coronary syndromes (ACS) in elderly patients receiving an early percutaneous coronary intervention (PCI) treatment. Methods The 162 elderly cases including unstable angina pectoris and non-ST -segment elevation myocardial infarction (NSTEMI) undergoing early PCI were enrolled in this study.And they were assigned to early treatment group (n=82) and deferred selective group (n=80)according to the time of using tirofiban (Gp Ⅱ b/Ⅲ a inhibitor) treatment. The effectiveness of either strategic option on tissue-level perfusion was evaluated using the TIMI myocardial perfusion grade (TMPG) before and immediately after PCI. The corrected TIMI frame count (cTFC) was also used to assess coronary artery flow and myocardial perfusion. Bleeding complications and the composite end point events at 30 days were also evaluated. Results Of all the 162 patients, the TMPG 0-1 perfusion was observed in 65 patients (40.1%). The TMPG 0-1 perfusion was significantly less frequent in early treatment group (32.9%) than in deferred selective group (47.5%) before PCI (x2=3.58, P<0.05); while the results of TIMI grade 0-1 flow (26.8% vs. 25.0%) and cTFC levels (34.2±11.8 vs. 34. 9±12. 7) before PCI were similar between the two groups (x2 =0. 07, P=0.47; t= 0.13, P=0.71, respectively). No differences were seen both in composite end point events at 30 days and bleeding complications (x2 = 0.31, P>0.05; x2=0.004, P>0. 05). Conclusions High -risk ACS patients treated with an early invasive strategy, routine upstream use of tirofiban are associated with improved tissue-level perfusion before PCI and does not increase bleeding complications when bleeding risks are carefully evaluated before enrollment.

ABSTRACT

BACKGROUND: Smoking is an important cause of cardiovascular disease, its definite mechanism in inducing cardiovascular disease is still unclear, and whether there is linear correlation between the amount of cigarette smoking and cardiovascular risk still needs to be investigated.OBJECTIVE: To analyze the association between cigarette smoking and the severity of coronary atherosclerosis.DESIGN: A retrospective investigation and comparative study.SETTING: The First Affiliated Hospital of Nanjing Medical University.PARTICIPANTS: Totally 500 consecutive patients, who underwent coronary angiography for suspected or known coronary atherosclerosis, were selected from the First Affiliated Hospital of Nanjing Medical University from April 2004 to April 2005. The inclusive criteria included patients with history of chest pain and/or ischemic changes of electrocardiography (ECG), and those with suspected or known coronary artery disease by coronary angiography. Patients with spastic angina pectoris (acetylcholine-positive) were excluded. Patients with infectious processes within 2 weeks before catheterization, heart failure (Killip Class≥ 2 after acute myocardial infarction), hepatic dysfunction, vascular disease (aortitis should be treated with prednisolone), familial hypercholesterolemia, thyroid dysfunction, or adrenal dysfunction were also excluded. There were 370 males aged 42-76years with an average of (61±11) years and 130 females aged 45-75 years with an average of (61±12) years. There were no significant differences in the sex, age and general information among all the patients. This study was approved by the ethics committee of the First Affiliated Hospital of Nanjing Medical University and informed consent was obtained from each patient.METHODS: ① According to the smoking habit, 500 patients with suspected or known coronary artery disease were divided into smoking group (n=254) and non-smoking group (n=246). ② All the patients received anthropometric measurements including body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP). Blood samples were drawn from every patient at admission to the detect the leukocyte counts in peripheral blood, including total leukocyte count, neutrophil count, eosinophil count, lymphocyte count, monocyte count and basophil count. ③ The severity of coronary atherosclerosis was defined by the Gensini score system, based on the hypothesis that the severity of coronary artery disease should be considered as a consequence of the functional significance of the vascular narrowing and the extent of the area perfused by the involved vessel or vessels. In this scoring system, a greater reduction of the lumen diameter was assigned a higher score than a distal lesion. ④The association of smoking amount with Gensini score, anthropometric measurements and leukocyte count were studies with the Spearman correlation analysis.MAIN OUTCOME MEASURES: ① Results of BMI, SBP, DBP, leukocyte count and Gensini score; ② Results of the Spearman correlation analysis on the association of smoking amount with Gensini score, anthropometric measurements and leukocyte count.RESULTS: ① The total leukocyte count, neutrophil count, monocyte count in peripheral blood and Gensini score were significantly higher in the smoking group than in the non-smoking group.② The Spearman correlation analysis indicated that the amount of cigarette smoking was significantly associated with the total cigarettes smoked, total leukocyte count,neutrophil count, monocyte count and Gensini score (r=0.109, 0.100,0.135, 0.139, P < 0.05-0.01).CONCLUSION: Smoking is significantly associated with the severity of coronary atherosclerosis, and the inflammatory response may be part of the mechanisms underlying the association between coronary artery disease and cigarette smoking.

ABSTRACT

BACKGROUND: As a common anticoagulant, heparin is widely used in clinic, but it has remarkable side effects such as severe bleeding and heparin-induced thrombocytopenia, and it cannot inactivate fibrin-bound thrombin. Annexin Ⅴ derivative (AND) is inosculated with C-terminal of hirudin and annexin Ⅴ, and its anticoagulation and anti-thrombosis effects are compared with those of heparin. OBJECTIVE: To investigate the relationship between quantitative effectiveness and time effectiveness of AND on coagulation and thrombosis, and study its reliability. DESIGN: Completely randomized grouping design and controlled study. SETTING: Cardiac Department of amunicipal hospital. MATERIALS: The experiment was conducted at the Animal Laboratory of Jiangsu Provincial People's Hospital from July 2000 to April 2001. Totally 32 male New Zealand white rabbits were randomly divided into 4groups, namely, high dosage AND group, low dosage AND group, common heparin group and saline group with 8 in each group. METHODS: Heparin and AND were diluted with saline.①High dosage AND group: 0.7 mg/kg AND was injected intravenously and followed by intravenous dripping of 0.35mg/(kg ·h)for 2 hours.Low dosage AND group: 0.3 mg/kg AND was injected intravenously and followed by intravenous dripping of 0.15 mg/(kg·h) for 2 hours. Heparin group: 75 IU/kg heparin was injected intravenously and followed by intravenous dripping of 37.5 IU/(kg·h) for 2 hours. Saline group: The same volume of saline and medication were used as those in drug groups.② Blood sample was collected from the femoral vein before administration so as to test blood routine, activated partial thromboplastin time(APTT)and prothrombin time (PT) after 15-, 30- and 60-minute administration and 2-hour withdrawal.③Saccule was separated from endothelium of femoral artery to measure blood pressure of distal femoral artery at 15 minutes after administration.Time of pulse pressure equal to 0 mmHg was recorded when the vessel was occluded completely by a thrombus.Finally the injured femoral arteries whose vessel was stripped were collected to measure its length, wet weight and dry weight. ④Observation of AND toxicity and sideeffects:During the experiment,vital signs of the animals were measured,such as blood pressure,heart rate and breath;in addition,bowelhemorrhage was observed and the number of leucocytes was counted after dissection of some of the animals. MAIN OUTCOME MEASURES:①Effect of AND on blood coagulation system and arterial thrombosis.②AND toxicity and side effects. RESULTS: All the 32 white rabbits entered the final analysis. ① Anticoagulant effect: APTT: Fifteen minutes after administration, APTT in AND group was the longest,which was(136.86±39.46)s in high dosage AND group and (122.90±34.19) s in low dosage ANDgroup.Moreover, APTT was longer than that in saline group [(95.14±24.64) s], but shorter than that in common heparin group [(180.00±0.00) s, P < 0.05, 0.01]. At 30 minutes after administration,AND in high dosage group still had coagulation,and APTT was (124.61±40.19) s in high dosage group, which was longer than that in saline group [(85.57±27.67) s], but APTT was (112.94±43.17) sin low dosage group,which was shorter than that in common heparin group [(85.57±27.67)s,P < 0.05].APTT was shorter in high and low dosage groups than in common heparin group at 60 minutes after administration (P < 0.05),and longer than that in saline group 2 hours after drug withdrawal,but there was not significant difference(P > 0.05).PT:PT in common heparin group was longer than that in high and low dosage groups at 15,30 and 60 minutes after administration (P < 0.05).② Effect on arterial thrombosis:Wet weight of thrombus:It was lighter in AND group than in common heparin group(P < 0.05). Dry weight of thrombus:Thrombus was lighter in high and low dosage groups than in common heparin group, and was lighter in high dosage group than in low dosage group (P < 0.05).Thrombus length:It was shorter in low dosage group than in saline group (P < 0.05), and shorter in high dosage groupthan in common heparin group (P < 0.05). Time of complete occlusion: It was longer in high and low dosage groups than in saline group(P < 0.05).③ AND toxicity and side effects:The behavior of rabbits in high and low dosage groups was similar to that in other two groups. Obvious hemodynamic changes were not found, and bowel hemorrhage was not observed, either. CONCLUSION: AND is an effective anticoagulant and anti-thrombosis agent; the highest anticoagulation effect occurs at 15 minutes afteradminis tration. However, the anticoagulant effect is poor as compared to heparin.The effect is poorer after 60-minute administration. Effect of AND on thrombus is stronger than that of heparin,but the size of thrombus is smaller than that of heparin, and the dosage-dependence manner was found. In addition, the anti-thrombus effect of AND is stronger in high dosage group than in low dosage group.
