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 compare spontaneous correction of the unfused thoracic curves after selective anterior versus posterior fusion in Lenke5 adolescent idiopathic scoliosis(AIS). [Method]A total of 72 Lenke5 AIS patients were rescruited from May 1997 to October 2005.Out of them,40 received selective anterior fusion(group A) and 32 received selective posterior fusion(group B).All had a minimum of 2-year follow-up.[Result] No complication were found in both groups at the latest follow-up.The thoracic curve was corrected from 30? to 16? for group A,33? to 18? for group B.Both groups had a better spontaneous correction of the unfused thoracic curves.The correction rate had no significant difference between groups.However,the thoracic curve was increased in four patients(2 in each group;group C),which resulted in trunk imbalance.The thoracolumbar/lumbar thoracic(TL/L:T) Cobb's ratio averaged 1.09 in the four patients whereas 1.59 in other 68 patients(group D).The flexibility of the thoracic curve had significant difference in group C and D(34.2% vs 57.3%).[Conclusion]Both of the surgical treatments can get a better spontaneous correction of the unfused thoracic curves.It is important to evaluate the.thoracolumbar/lumbar–thoracic(TL/L:T) Cobb's ratio and the flexibility of the thoracic curve before selective fusion.

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.
