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.

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 investigate the correlation of serum advanced glycation end products (AGEs) and the expression of receptor for AGE (RAGE) with mental disorders in senile people. Methods All the subjects aged 65～67 years were divided into 4 groups: healthy control (31 cases), Alzheimer's disease (AD) (36 eases), vascular dementia (VD) (20 cases) and mental disorder (MD) (28 cases). Fluorospectrophotometry was carried out to measure the AGEs levels in serum samples, and reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA levels of RAGE in white blood cells. Results AGEs levels were 477. 1±36.2, 512. 6±33.2 and 415.2±32.5 AU/ml in AD, VD and MD group, respectively, which were higher than that in healthy control group (357.4±28. 2) AU/ml (F=3.77,P<0. 05). The mRNA levels of RAGE(RAGE/b- actin) were found to be 1.12±0.34, 1.27±0.41 and 1.18±0.42 in AD, VD and MD group, respectively, which were also significantly higher than that in healthy control group(0. 92±0. 37, F= 4. 07,P<0. 01). However, no significant differences were found in RAGE mRNA levels among the three groups of AD,VD and MD (F=0. 979,P>0. 05). The mRNA levels of RAGE in WBCs were found to be positively correlated with the serum AGEs levels (r=0. 442, P<0. 01). Conclusions Compared with patients in healthy control group, the serum AGEs levels and RAGE mRNA levels are significantly increased in patients with AD, VD and MD. The interaction between AGEs and RAGE may be involved in the pathogenesis of mental disorders in senile people.

Objective To evaluate the practicality of MAGE-1 and MAGE-3 genes encoding proteins used as a target for immunotherapy in renal cell carcinoma and urinary transitional cell carcinoma patients. Methods Reverse transcriptase-polymerase chain reaction (RT-PCR) was used for detection of MAGE-1 and MAGE-3 genes in the specimens from renal cell carcinoma (n=18) and urinary transitional cell carcinoma (n=26),and in 10 specimens taken from the tumor surrounding tissues. Results Positive expression of MAGE-1 and MAGE-3 genes at mRNA was detected in 10(56%) and 11(61%),respectively,of 18 cases of renal cell carcinoma;and expression of both MAGE-1 and MAGE-3 in 8(44%).Out of 26 cases of urinary transitional cell carcinomas,16 (62%) expressed MAGE-1 and 15 (58%) expressed MAGE-3;and 12 (46%) expressed both MAGE-1 and MAGE-3.No expression of MAGE-1 or MAGE-3 was detected in 10 specimens from tumor surrounding tissues. Conclusions The tumor-specific antigens MAGE-1,MAGE-3 genes might be used as molecular markers and specific targets of immunotherapy and gene therapy for renal cell carcinoma and urinary transitional cell carcinoma.
