围生期心肌病发病相关因素的研究

Objective To explore the risk factors of peripartum cardiomyopathy (PPCM). Methods A total of 82 PPCM and 100 normal delivery females were randomly recruited in the current study. Echocardiographic, cTNI,high sensitive C-reaction protein(hs-CRP) ,NT-proBNP were measured. Fifty-two patients were followed up for a mean of 6 months. Results The PPCM patients (29. 5 ± 6. 4) yrs were older than the controls (25. 2 ± 5. 8) yrs (P<0.01) . Compared to the controls, the PPCM patients showed higher blood pressure (146.9/98. 8 mm Hg v. s. 130. 2/80. 1 mm Hg, P < 0. 01) , higher proportion of cesarean section (65. 9% v. s. 51. 0% , P < 0. 05) and complicated infection(75. 6% v. s. 10. 0% ,P <0. 01). The level of leucocyte(11.0 × 109/L) ,cTNI(0. 17 μg/L), hs-CRP(28. 2 mg/L)and NT-proBNP(650. 1 ng/L) were significantly higher in the PPCM patients compared with control(8. 8 × 109/L,0. 06μg/L,6. 2 mg/L and 110. 5 ng/L,P <0. 01). Hs-CRP was positively related with NT-proBNP(r = 0. 67, P < 0. 01). After average of 6 months of treatment, left ventricular ejection fraction enhanced from 32. 2% to 50. 6%. NT-proBNP significantly declined from 650. 1 ng/L to 225.6 ng/L(P <0. 01). Multiple linear regression analysis showed that diastolic pressure (P < 0. 05), LVED (P < 0. 05) and hs-CRP (P < 0. 05) were the independent predictors for declined NT-proBNP. Conclusions Inflammatory plays an important role in the development of peripartum cardiomyopathy.

Objective To examine the relationship between hematocrit and risk of long term mortality among patients with acute myocardial infarction. Methods A total of 274 patients with acute myocardial infarction were recruited and divided into two groups by death after long term follow-up, the relationship between hematocrit and mortality was evaluated through the methods of independent t-test,chi-square test and multivariate regression analysis. Results The mean age was 69. 79 ± 7.45 years, with 73. 0% of male. The average of followup was 44. 4± 10. 7 months, with mortality of 38.7% . Comparison of baseline data showed that NYHA classification, smoking history, hemoglobin, hematocrit, mean red cell volume, glomerular filtration rate, ejection fraction,left ventricular diastolic diameter and right ventricular diameter was significantly different between the two groups( Ps ＜ 0. 05), Multivariable logistic analysis showed that hematocrit ,glomerular filtration rate, ejection fraction and smoking history were independently predicted factors, with OR of 0. 904 (95% CI: 0. 832 - 0. 982,P =0. 016) ,0. 983 (95% CI: 0. 969 -0. 996,P =0. 014) ,0. 932 (95% CI: 0. 887 -0. 979,P =0. 005) and 3. 230 (95% CI: 1.468 - 7. 106, P = 0. 004), respectively. The power of hematocrit to predict mortality was examined by ROC curves, the area under the curve was 0. 669(P ＜ 0. 001,95% CI: 0. 603 - 0. 736) Conclusion Hematocrit is a significant independent predictor for long term death among patients with acute myocardial infarction.

脓毒症早期血清白细胞介素-18和10在疾病严重程度及预后评估中的价值研究

Objective To observe the dynamic changes in levels of serum interleukins (IL-18, IL-10)in the early stage of sepsis, and to appraise their values in the evaluation of severity and prognosis of sepsis.Methods Prospective randomized controlled study was conducted. Thirty-eight patients with sepsis who stayed longer than 72 hours in intensive care unit (ICU) from December 2009 to August 2010 were enrolled as sepsis group. At the same time, 20 patients without sepsis served as control group. The patients were classified as survival (n=12) or death group (n = 26) according to 28-day survival. The clinical laboratory examination data were recorded at 24, 48, 72 hours after admission to the ICU, and venous blood was obtained at the same time. The IL-18, IL-10 levels were determined by enzyme-linked immunosorbent assay (ELISA). Results The vital signs, blood routine, liver function, renal function, coagulation function,arterial blood gas, and electrolyte showed no significant difference between sepsis group and control group 24, 48, 72 hours after admission, the levels of IL-18 were lowered, IL-10 elevated, the IL-18/IL-10 ratio was lowered in the sepsis group, and all of them were higher than control group at each time point. The levels of IL-18, IL-10 in death group of patients with sepsis were all higher than those of survival group at 24, 48, and 72 hours [IL-18 (ng/L): 108. 36± 18. 54 vs. 91. 66±21. 49, 92.13±28. 92 vs. 54.16±31.76,91. 78 ± 17. 33 vs. 76. 04 ±22.09; IL-10 (ng/L): 99. 42 ± 12.10 vs. 77. 20 ±9. 47, 103. 39 ± 17. 24 vs.67.88±18.90, 118. 99 ±11. 20 vs. 99. 20± 12. 46, P＜0. 05 or P＜0. 01]. IL-18/IL-10 ratios were all lowered in both non-survivors and survivors with sepsis at 24, 48, 72 hours, while the differences were not statistically significant (1. 09±0. 19 vs. 1. 20±0. 32, 0. 92±0. 18 vs. 0. 98±0. 29, 0. 78±0.15 vs. 0. 77±0. 23, all P＞0. 05). Conclusion The levels of serum IL-18, IL-10 were all elevated in the early stage of patients with sepsis, and in non-survivors they were higher than those of survivors. With the progress of the illness, IL-18 showed a lowering tendency, while IL-10 showed an elevation. The levels of serum IL-18 and IL-10 may be valuable in evaluating the severity of sepsis and prognosis of patients with sepsis.

高糖诱导人脐静脉内皮细胞衰老过程中活性氧与二甲基精氨酸二甲胺水解酶-非对称性二甲基精氨酸系统的变化

Objective To investigate the changes in reactive oxygen species (ROS) and dimethylarginine dimethylaminohydrolase-asymmetric dimethylarginine (DDAH-ADMA) system in the process of endothelial cell senescence after exposure to high glucose. Methods The human umbilical vein endothelial cells (HUVECs) were cultured with different concentrations of glucose, e.g. 5. 5 mmol/L (normal level),and high levels as 11. 0, 22. 0 and 33. 0 mmol/L. for 48 hours, respectively. Subsequently, SA-β-gal staining was used to evaluate senescence of cells. Telomerase activity was detected by polymerase chain reactionenzyme linked immunosorbent assay (PCR-ELISA). The intracellular ROS level was measured by flow cytometry. The ADMA concentration and DDAH activity were determined with high-performance liquid chromatography. Results Compared with normal glucose concentration group, after the endothelial cells were treated with high glucose concentration (11. 0 - 33. 0 mmol/L) for 48 hours, the number of SA-β-gal positive cells was increased significantly [(7.00±1. 73)%, (12. 67±2. 03)%, (16. 00±2. 26)% vs. (4. 00±1.33)%, P＞0.05, P＜0.05, P＜0.05] and the telomerase activity was inhibited dramatically [(91. 32±4.01)%, (78. 44±3. 78)%, (56. 04±3. 35)% vs. 100%, all P＜0. 05]. The ROS level (mfi) was increased in all high glucose groups (159. 84±27. 52, 188. 99±18. 77, 244. 56±20. 96 vs. 117.11±18. 76, P＜0. 05 or P＜0. 01). At the same time, the ADMA (μmol/L) production was increased (0. 78±0. 14, 0. 88±0.18,1. 08±0.15 vs. 0. 70±0. 12, P＞0. 05, P＜0. 05, P＜0. 05), and DDAH activity was decreased [(91. 32±4.01)%, (78.44±3.78)%, (56. 04± 3. 35)% vs. 100%, all P＜0.05]. Conclusion High glucose can accelerate endothelial cells senescence in dose-dependent manner and the underlying mechanism may be related to an increased oxidative stress and change in DDAH-ADMA system.
