Chinese Journal of Postgraduates of Medicine 2006;0(01):-
Objective To investigate the changes and the significance of the contents in matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in plasm of patients with intracerebral hemorrhage (ICH). Methods The contents of MMP-2 and MMP-9 in plasm of 50 patients with ICH and 50 healthy people (control group) were measured respectively through ELISA methods. Results Compared with the control group,the increase of the contents of MMP-2 and MMP-9 had obvious statistic significance in plasm of patients with ICH (P0.05),but they had obvious statistic significance in the comparison among other time groups (P

Objective To observe the serum cardiac troponin I (cTnI) level and to analysis the relations between the serum cTnI level and prognosis in patients with dilated cardiomyopathy (DCM) and Cardiac Dysfunction.Methods Serum cardiac cTnI level was measured by enzyme-linked immunosorbant assay. Results The serum cTnI level in DCM patients with class IV cardiac function (0.53 ?0.31) ?g/L was significantly higher than in DCM patients with class Ⅲ cardiac function (0.45?0.27) ?g/L.There was significantly difference in serum cTnI levels between DCM patients with class Ⅲ cardiac function and DCM patients with class Ⅱ cardiac function(0.29?0.27) ?g/L.Conclusion The higher serum cTnI level is correlated with the severity of cardiac function and may be useful for evaluating prognosis in patients with DCM.

Journal of Environment and Health 1992;0(02):-
Objective To determine whether repeated cold-stress stimulation could activate rennin-angiotensin system in rats and lead to a PIH-like phenomena in pregnant rats.Methods Adult Wistar female rats were randomly divided into 4 groups: non-pregnant control group(NN), non-pregnant cold-stress group(NC), pregnant control group(PN) and pregnant cold-stress group(PC). Rats were kept for 4 hours in (4?2)℃(NC?PC) and in 25℃ (NN?PN) every day respectively, from the 1st day to the 19th day of pregnancy. The AngⅡlevels of plasma?uterus and placentas were determined by radioimmunoassay. The expression of angiotensin Ⅱ type 1 receptor (AT1R) and angiotensin Ⅱ type 2 receptor (AT2R) mRNA were determined in uterus and placentas of rats by RT-PCR. Results The AngⅡlevels of plasma, uterus and placentas were increased significantly in NC and PC compared with those in NN and PN. AT2R was the predominant type in the rat non-pregnant uterus. Downregulation of AT2R and upregulation of AT1R were observed during pregnancy. And at last, AT1R was the predominant type in pregnant uterus. The AngⅡ receptors in the rat placenta are predominantly AT1R. After cold-stress stimulation, the expression of AT1R mRNA in uterus and placentas of rats were higher than that of control groups(P0.05). Conclusions Repeated cold-stress stimulation could activate the renin-angiotensin system(RAS), and lead to a PIH-like phenomena in pregnant rats at last.

Objective To summarize treatment experiences of microsurgical clipping for anterior communicating artery aneurysm via pterional approach.Methods Clinical data of 82 cases undergoing microsurgical clipping for anterior communicating artery aneurysm via pterional approach in the first affiliated hospital of Kunming Medical University from October 2008 to December 2014 were collected and retrospectively analyzed.The patients were divided into different groups by Hunt-Hess illness grading scale,with 11 cases for level 0,7 cases for level Ⅰ,30 cases for level Ⅱ,25 cases for level Ⅲ,8 cases for level Ⅳ,and 1 cases for level Ⅴ.Twenty-one patients underwent operation at early stage of SAH (<3d),15 at late stage of SAH (4d~2W),and 35 at prolonged stage of SAH (>2W).The prognosis of patients was evaluated according to GOS classification criteria at discharge.Results A total of 85 ACoAA were found in 82 patients and all of them were clipped and,at the same time,3 aneurysms were resected and 11 thrombuses were punctured,cut and removed.In the operation,15 (17.6%) aneurysms ruptured again and temporary blocking happened for 73 times,with the shortest blocking time of 2 rmin,the longest of 40 rmin,and the average of 9.26min.According to GOS score,good recovery rate was 79.3% (65/82),moderate disability rate was 12.2% (10/82),severe disability rate was 3.7% (3/82),vegetative state rate was 0%,and death rate was 4.9% (4/82).Good recovery rates for the operations at early,late and prolonged stage of SAH were 85.7%,73.3% and 82.3% respectively and for level 0 to level Ⅴ were 90.9%,85.6%,86.7% and 84.0%,25.0% and 0.0% respectively.Results of DSA or CTA re-examination upon 55 patients followed-up at discharge or three months after discharge showed that tumor pedicle were clipped and aneurysm disappeared.Fifty cases were followed up from four months to seven years after the operation,with one case of aneurysm recurrence.Another thirty-two cases were lost to follow-up.ConclusiornS Microsurgical techniques and microdissection are keys to successful operation.Pterional approach can guarantee successful clipping of aneurysms with different directions,locations and sizes.It is also an easy,effective and reliable approach with less postoperative complications.Operation for anterior communicating artery aneurysm should be performed as early as possible.

Objective To explore the change rule and clinical application value of hemorheologic indexes in patients with acute intracerebral hemorrhage ( ICH) . Methods The hemorheology indexes of 100 acute ICH patients ( ICH group) were detected within 24 h, and compared with 30 normal controls ( normal control group) . The effect of hemorheology index on history of hypertension, hemorrhage quantity and the hemorrhage location were analyzed. Results Compared with those in normal control group, the indexes of whole blood viscosity, plasma viscosity and erythrocyte sedimentation rate were significantly increased and erythrocyte aggregation index, erythrocyte deformability index and hematocrit were significantly decreased in acute stage ( all P< 0. 01 ) . Blood rheology indexes were changed significantly in hypertensive cerebral hemorrhage group (all P<0. 01), the whole blood viscosity (200 s-1 and 50 s-1 ) , erythrocyte aggregation index, hematocrit and erythrocyte sedimentation rate in non-hypertensive cerebral hemorrhage group were changed significantly ( P< 0. 05 - 0. 01 ). Compared with normal the non-hypertensive cerebral hemorrhage group, the whole blood rheology indexes except erythroate sedicmnt ation rate significantly erythrocyte sedimentation rate were significantly changed ( P< 0. 05 ) . As the hemorrhage quantity increased in each groups, the whole blood viscosity ( 200 s-1 and 50 s-1 ) and plasma viscosity of cerebral hemorrhage patients were significantly increased, otherwise the erythrocyte aggregation index was significantly decreased (P<0. 05-0. 01). There were statistical differences compared the indexes of whole blood viscosity (200 s-1 and 1 s-1 ) , plasma viscosity, erythrocyte aggregation index and erythrocyte sedimentation rate among each groups of different hemorrhage locations in acute ICH patients (all P<0. 05). Conclusions The blood of acute ICH patients shows a state of concentrated, sticky, aggregation and coagulation that severely affects the prognosis. The patients with hypertension and greater hematoma changed obviously, different hemorrhage location affected differently.
