Abstract:
Objective To observe the changes of postoperative blood high sensitive C-reactive protein (hs-CRP), tumor necrosis factor(TNF)-o, P-selectin levels in patients with acute coronary syndrome (ACS) who had an atorvastatin intensive treatment before operation, and investigate its clinical significance.Methods Seventy-eight cases of ACS patients who intended to undergo percutaneous coronary intervention were divided into two groups by random digits table:39 patients comprising the standard treatment group (given atorvaatatin 20 mg/d, conventional treatment), 39 patients comprising the enhanced group (given atorvastatin 40 mg, 20 mg separately at preoperative 12 h, 2 h on the basis of conventional treatment).Among them, 28 cases of the standard treatment group and 29 cases of the enhanced group finally underwent the test. The hs-CRP,TNF-α ,P-selectin levels at preoperative 1 day,postoperative 6 h,postoperative 12 h were detected and then the changes of three factors were analyzed. Results There was no significant difference in hs-CRP,TNF- α, P-selectin between the two groups at preoperative 1 day. The values of the two groups markedly increased at postoperative 6 h, 12 h and the difference was statistically significant (P <0.05). The values of the standard treatment group were markedly higher at postoperative 12 h than those at postoperative 6 h,and the difference was statistically significant [hs-CRP: (10.29 ± 0.77) mg/L vs. (6.34 ±1.23) mg/L;TNF-α: (58.15±5.19) ng/L vs. (36.12 ± 3.89) ng/L;P-selectin: (49.58 ±4.92) μg/L vs.(31.47 ± 3.71) μ g/L] (P < 0.05). However, the values of the enhanced group were higher at postoperative 12 h than those at postoperative 6 h but the difference was no statistically significant [hs-CRP: (6.83 ± 1.46)mg/L vs. (5.95 ± 1.17) mg/L; TNF- o: (42.18 ± 7.79) ng/L vs. (34.07 ± 8.79) ng/L; P-selectin: (33.57 ±4.63) μ g/L vs. (29.78 ± 5.61) μ g/L] (P > 0.05). Three factors in standard treatment group were elevating significantly at postoperative 6 h, 12 h compared with those in the enhanced group, but the difference was no statistically significant (P > 0.05). Conclusion Short-term intensive therapy of atorvastatin in ACS patients who intend to do PCI, can reduce the hs-CRP, TNF-α, P-selectin levels effectively.  相似文献

Abstract:
Objective To explore the clinical utility of the sinus rhythm turbulence in the patients with acute myocardial infarction (AMI). Methods All day the dynamic electrocardiogram was monitored in 36 patients with AMI (AMI group) and 60 healthy subjects with ventricular premature beat (VPB) (control group),the TO value and TS value after VPB was compared between two groups. Results The TO value after VPB in AMI group was higher than that in control group (P<0.01), the TS value after VPB in AMI group was lower than that in control group (P < 0.01). The TO value in the non-survivors with AMI was higher than that in the survivors,while their TS value was lower with a significant difference (P< 0.01). The irregular positive rate of the TO value and the TS value in the patients with AMI was 58.1%(50/86) and 67.4%(58/86), while that of the healthysubjects was 16.7%(10/60) and 10.0%(6/60) with a significant difference (P < 0.05). The research from the follow-up visit of the selected patients in 2 years showed that death rate of the patients with both irregular TO and TS was 46.2% (24/52), the death rate with either irregular TO or TS was 25.0%(7/28), the death rate with both regular TO and TS was 16.7%(1/6), and the difference of the three phenomenon was significant (P < 0.01). Conclusion As long as the sinus rhythm turbulence of the patients with AMI disappears or declines,the death rate increases, and to monitor and analyze their TO and TS in time is helpful for us to avoid the sudden death of the patients and to discover the levels of their risks.  相似文献

Abstract:
Objective To observe the perioperative myocardial protection of high-dose atorvastatin to acute coronary syndrome(ACS) patients during percutaneous coronary artery interventional therapy(PCI).Methods One hundred and twenty patients with ACS undergoing elective PCI were divided into group A and group B with different oral dose of atorvastatin ( 80 mg/d and 20 mg/d ) for 3 days before operation by random digits table. Troponin I (cTnI), creatine kinase isozyme MB (CK-MB), high sensitive C-reactive protein (hs-CRP), interleukin (IL)-6 levels were measured before operation, 6 hours, 12 hours after operation and total cholesterol (TC), triglyeride (TG), low desity lipeprotein cholesterol (LDL-C), high density lipeprotein cholesterol (HDL-C) levels were measured before operation and 3 days after operation.Results cTnI,CK-MB,hs-CRP and IL-6 levels in the two groups were increased significandy 6 hours and 12 hours after operation (P <0.05). Six hours after operation, cTnI and CK-MB levels in group A were significantly lower than those in group B [(0.35±0. 18 ) μg/L vs. (0.48±0. 16 ) μg/L, ( 3.78±0.45 )μg/Lvs. (4.56±0.55 )μg/L] (P < 0.05 ). Twelve hours after operation , hs-CRP and IL-6 levels in group A were significantly lower than those in group B [(4.53±0.98 ) mg/L vs. (7.03±0.88 ) mg/L, ( 30.6±11.2) ng/L vs.(43.8±12.1) ng/L] (P <0.05). TC, TG, LDL-C, HDL-C levels in the two groups did not change significantly before and after operation (P >0.05). Conclusions Myocardial protective effects of ACS patients treated with atorvastatin 80 mg/d for 3 days are better than those treated with oral atorvastatin 20 mg/d. High-dose atorvastatin can produce more beneficial effects.  相似文献

Abstract:
Objective To explore the changes and the clinical significance of 5-hydroxytryptamine (5-HT), dopamine (DA) levels in serum and cerebrospinal fluid (CSF) of patients with delayed encephalopathy(DEACMP)after acute carbon monoxide poisoning. Methods The dynamic detection of 5-HT and DA levels in serum and CSF from 42 patients with DEACMP was performed with high performance liquid chromatography (HPLC). The condition changes of patients with DEACMP were analyzed with three types of scales: the activity of daily living scale (ADL), information memory concentration test (IMCT) and Hasegawa's dementia scale(HDS); these changes were compared with those from 38 other encephalopathy patients and 38 nonencephalopathy patients, respectively. Results Before treatment, the serum 5-HT and DA levels [(662.61 ± 178.50) and (155.74± 60.32) nmol/L, respectively] of DEACMP group were both significantly lower than those[(914.08±198.04) and (225.70±48.53) nmol/L] of nonencephalopathy group (P<0.05); the serum DA level of DEACMP group was also significantly lower than that [(243.57±66.94) nmol/L] of other encephalopathy group (P<0.05); the serum 5-HT level of DEACMP group was not significantly different from that [(729.54±299.87 ) nmol/L] of other encephalopathy group (P>0.05). After treatment, the serum 5-HT and DA levels[(714.08±170.47) and (192.18±33.07 nmol/L, respectively)] of DEACMP group elevated to various extent, but only serum DA level was significantly higher than that before treatment (P<0.05). Before treatment,the CSF 5-HT and DA levels of DEACMP group were significantly lower than those of nonencephalopathy group and those of other encephalopathy group (P<0.05). After treatment, the CSF 5-HT level (232.44±54.28 nmol/L) was similar to normal level and significantly higher than that before treatment (P<0.05); the CSF DA level[(56.83±12.85) nmol/L] of DEACMP group increased only slightly (P>0.05). In DEACMP group, ADL score (50.64±7.23), HDS score (8.55±8.08) and IMCT score (4.95±7.30) before treatment were significantly different from those (8.5 ± 8.08, 4.95 ±7.30 and 15.64 ± 10.90) after treatment (P<0.01). In DEACMP group, there was a negative correlation between DA level changes and HDS score changes, when the DA levels and HDS scores before treatment were compared with those after treatment (P<0.05). Conclusion The dynamic changes of 5-HT and DA levels in serum and CSF of patients with DEACMP consisted basically with the patient's condition change. The dynanically detected 5-HT and DA levels can be used as the biological indicators to reflect the condition change and treatment effects of DEACMP patients.  相似文献

Abstract:
Objective To explore sinus heart rate turbulence (HRT) in patients with different subtypes of essential hypertension (EH), and analyze the relationship between HRT and autonomic nervous system function damage in these patients. Methods The study consisted of 107 patients with EH (EH group) and 46 controls (control group). Based on 24 hours dynamic electrocardiogram, all patients were divided into dipper,non-dipper,and anti-dipper blood pressure group. The indexes about HRT and heart rate variability (HRV) among these groups were calculated and compared,and the relationship between turbulence onset (TO),turbulence slope (TS) and 24 hours mean systolic blood pressure,diastolic blood pressure was analyzed. Results There were significant differences in TO,TS,SDNN between EH group and control group(P < 0.05 ). TO in non-dipper and anti-dipper blood pressure group was significantly higher than that in control group( P < 0.05 ), and TS was lower than that in control group(P < 0.05 ). There was no significant difference in TO,TS between dipper blood pressure group and control group (P > 0.05). TO in non-dipper and anti-dipper blood pressure group was significantly higher than that in dipper blood pressure group, but TS was lower than that in dipper blood pressure group (P <0.05). Correlation analysis showed that TO had positive relationship with average heart rate and age (rs = 0.265, P = 0.004;rs = 0.217, P = 0.018 ), but had negative correlation with SDNN and left ventricular ejection fraction (LVEF) (rx = -0.287,P = 0.002;rx =-0. 179, P = 0.049). Whereas, TS had negative correlation with average heart rate and age (r = -0.335, P =0.015 ;r = -0.238,P= 0.009), but had positive relationship with SDNN and LVEF(r = 0.540,P = 0.001 ;r =0.432,P = 0.001 ). Conclusions HRT of EH patients becomes significantly low. It suggests that the autonomic nerve function in EH patients be injured seriously.  相似文献

Abstract:
Objective To explore the effects oflosartan on brain natriuretic peptide(BNP)and C-reactive protein(CLRP)in diabetic cardiomyopathy patients. Methods Sixty diabetics were divided into diabetic control group(30 cases)and diabetic cardiomyopathy group(30 cases), and the levels of BNP and CRP in plasma were determined. Then, diabetic cardiomyopathy group were divided into conventional treatment group(15 cases)and losartan treatment group(15 cases)by random digits table to take corresponding treatment for 12 weeks. The changes of cardiac function, the levels of BNP and CRP in plasma were detected and compared. Results The levels of BNP and CRP in diabetic cardiomyopathy group [(331.27 ±65.64)ng/L,(26.10±10.13)mg/L]were significantly higher than those in diabetic control group[(76.09±39.14)ng/L,(7.03±2.71)mg/L](P<0.01). After treatment 12 weeks, the levels of BNP and CRP were significantly lower, left ventricular ejection fraction was significantly higher and left ventricular end-diastolic diameter was significantly lower in losartan treatment group than those in conventional treatment group(P<0.05).Conclusions The increasing levels of BNP and CRP can reflect clinical severity of diabetic cardiomyopathy.Losartan can decrease the levels of BNP and CRP, and improve heart function, and it has better effective on diabetic cardiomyopathy.  相似文献

Abstract:
Objective To observe the change of oxidalive stress indexes in the patients with diabetic perineuropathy (DPN), and investigate the protection role of glutathione (GSH) on neuroprotective effect. Methods The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) and sensory nerve conduction velocity (SCV) were detected in 54 cases with DPN (DPN group) and 30 cases of health examination (control group). Fifty-four cases with DPN were divided into GSH group (given basic treatment and GSH 1.8 g/d) and CON group(given basic treatment and B vitamin) with 27 cases each by random-digits table. After treatment of 2 weeks, the levels of SOD, MDA and SCV were compared. Results The levels of MDA in DPN group were significantly higher than those in control group, while the activity of SOD was significantly lower than that in control group [(7.23 ±2.31) μmol/L vs. (4.87 ± 1.17) μmol/L, (59.72 ± 13.58) kU/L vs. (76.19 ± 7.55 ) kU/L](P< 0.01). After treatment, the level of MDA was decreased and the activity of SOD was increased in GSH group and CON group (P <0.05),but there was no significant difference between the two groups(P> 0.05). After treatment, the level of SCV was significantly increased in GSH group,while there was no significant difference in CON group (P >0.05). Conclusions Oxidative stress exists in DPN patients. The antioxidant treatment with GSH can improve impaired nerve and has a better effect of nerve protection than classical nerve nutrition therapy.  相似文献
