Objective To study the correlations among the lipoprotein associated phospholipase A2 (Lp‐PLA2) ,hypersensitive C‐reactive protein(hs‐CRP)and D‐dimmer in patients with the coronary heart disease .Methods 260 cases of patients with coronary heart disease(CHD) were enrolled in the study as observation group and 260 healthy people from the physical examinations were recruited as control group .The concentrations of Lp‐PLA2 ,hs‐CRP ,D‐dimer and other biochemical indicators in blood sera of the two groups were detected ,using the Spearman correlation analysis to test the relationship between those indicators .Results The Lp‐PLA2 ,hs‐CRP ,D‐dimer levels of the observation group were obviously higher than those of control group .The Lp‐PLA2 level of the observation group was positively correlated with the cardiac function index(r=0 .873 ,P<0 .05) .hs‐CRP was positively cor‐related with cardiac function index(r=0 .782 ,P<0 .05) .D‐dimmer was positively correlated with the functional grades of heart(r=0 .674 ,P<0 .05) .Conclusion Lp‐PLA2 ,hs‐CRP and D‐dimer could be important indicators for the detection of coronary heart disease .

Objective To retrospectively analyze the effects of nerve block anesthesia versus general anesthesia on intertrochanteric fracture in the elderly. Methods The 104 elderly inpatients undergoing closed reduction and intramedullary nailing for the treatment of femoral intertrochanteric fractures were recruited into this study at Department of Orthopedics ,Xiangya Hospital ,Central South University from January 2015 to June 2017.Medical records were collected and analyzed by SPSS 16.0 or GraphPad Prism 6.0 software. Results A total of 104 patients were divided into general anesthesia group(n= 48 )and nerve block anesthesia group (n= 56 ). There was no statistical difference in the demographic characteristics between the two groups. The changes in heart rate ,maximum changes of systolic/diastolic blood pressures ,and infusion volume during surgery were lower in the nerve block anesthesia group than in the general anesthesia group [(12.7 ± 7.3)vs. (18.1 ± 7.8)beats/min ,(22.5 ± 8.8/12.2 ± 7.5)mmHg vs. (34.3 ± 7.9/21.6 ± 6.6)mmHg ,(792.9 ± 387.0)ml vs. (1 083.0 ± 445.5)ml ,respectively ,t=3.64 ,7.14 ,6.73 ,5.16 ,all P＜0.01]. There was no statistically significant difference between two groups in other perioperative data and the number of deaths at three months and one year after surgery. Conclusions As compared with the general anesthesia ,the nerve block anesthesia has less effects on the heart rate ,less maximum changes of systolic and diastolic blood pressures ,and less infusion volume during surgery ,and has no significant increase in postoperative mortality ,which is safe and worthy of further promotion.
