BACKGROUND: D-dimer is the specific marker of cross-link fibers degraded by fibrinolysin. During cerebral hemorrhage, D-dimer is significantly increased; its decrease may reflect the absorption process of hematoma and be closely related with the substantial injuries of brain. Endothelin is remarkably increased during cerebral hemorrhage, which may result in ischemic necrosis of neural histiocytes. The endothelin volume in cerebral hemorrhagic patients can reflect the severity of illness and the function prognosis.OBJECTIVE: To observe the effect of xingnaojing he shengmai injection (compound injection) on D-dimer and endothelin in patients at acute stage of cerebral hemorrhage.DESIGN: A randomized and controlled trial.SETTING: Emergent Internal Department of the Affiliated Hospital of Medical College of Qingdao University and Department of Pathology of Jinan Military General Hospital.PARTICIPANTS: A total of 44 patients of inspected patients at acute stage of cerebral hemorrhage were collected in Emergent Internal Department of affiliated Hospital of Medical College of Qingdao University from September 1999 to May 2001, which were randomized into two groups, named as xingnaojing he shengmai injection(compound injection) group(23 patients) and xingnaojing group(21 patients).METHODS: ELISA method was applied to determine the level of D-dimer and endothelin of peripheral blood before and after treatment. SPSS 8.0 statistical software was applied to analyze the data.MAIN OUTCOME MEASURES: Effects of xingnaojing he shengmai injection(compound injection) on level of D-dimer and endothelin in patients at acute stage of cerebral hemorrhage, compare with xingnaojing group.RESULTS: Xingnaojing he shengmai injection(compound injection) significantly reduced the level of both D-dimer[ (0. 67 ± 0. 21), (0.34 ± 0.18) mg/L,P ＜ 0.01 ] and endothelin[ (94.52 ±30. 23), (51.30 ± 21.62) ng/L, P＜ 0.01 ] before and after treatment respectively. The improvement of which was obviously superior to those in xingnaojing group[ (0. 33 ±0. 11),(0.20±0.08)mg/L, P ＜0.01; (43.22±12.06), (26.52±8.13)ng/L respectively, concerning to the improvements in two groups, P ＜ 0. 01 ].CONCLUSION: To improve the fibrinolytic state in patients with cerebral hemorrhage may protect the substantial injuries of brain and prevent the secondary damage after cerebral hemorrhage. To inhibit cerebral vascular spasm after hemorrhage may improve ischemic oxygen deficiency in brain tissue and probably be taken as one of the ways for xingnaojing he shengmai injection giving play to its therapeutic effects.

Objective To evaluate the value of serum galactomannan (GM) detection for invasive pulmonary aspergillosis (IPA) diagnosis. Methods The suspicious IPA patients were divided into proven,clinical and possible IPA groups. The patients excluded of IPA were recruited as controls. The serum GM concentration was detected by Platelia Aspergillus double?sandwich enzyme linked immunosorbent assay(ELISA). Re?sults In the 103 patients,there were seven cases diagnosed as proven,nineteen cases diagnosed as clinical and forty cases diagnosed as possible IPA patients. Setting 0.5 as the optimal result for GM detection,the sensitivity,specificity,positive predictive values and negative predictive values of GM were 85.7%,86.5%,55%and 97%,respectively. In non?neutropenia patients combinded with the pulmonary chronic diseases,the sensitivity, specificity,positive predictive values and negative predictive values of GM detection were 71.4%,84.4%,66.75%and 87.1%,respectively. Conclu?sion Index>0.5 for GM test could increase the sensitivity without obvious decreased specificity. GM detection could provide valuable information in patients of non?neutropenia underlying the pulmonary chronic diseases,which had a better sensitivity and specificity versus conventional diagnostic tests.

Objective To detect steroidogenic acute regulatory protein (StAR) expression in apolipoprotein E-deficient mice at different ages and serum lipid levels. Methods Nighty-six C57BL/6J and apoE-/- mice were enrolled, which were divided into 16 groups with 6 mice per group according to age (1 day, 1, 3, 5 months), sex and genotype (C57BL/6J and apoE-/-). The serum lipid levels in C57BL/6J and apoE-/- mice were detected by commercial kits. StAR mRNA and protein expressions in liver were detected by Real-time PCR and Western blot respectively. Results ApoE-/- mice had higher LDL-cholesterol and lower HDL-cholesterol compared with C57BL/6J mice of the same age and sex. StAR mRNA and protein expressions were decreased following with aging in C57BL/6J mice. However, in apoE-/- mice with higher lipid levels, StAR mRNA and protein expressions were changed with the lipid levels other than ages. StAR mRNA and protein increased in the early stage, and then decreased with the increasement of lipids levels. Conclusions StAR could affect lipids levels and may be an effective regulator for atherosclerosis and other cardiovascular diseases.
