Objective To review retrospectively the clinical experience in surgical treatment of congenital subaortic stenosis in 21 cases. Methods A total of 21 cases of congenital subaortic stenosis, including 12 cases of diaphragmatic type of stenosis and 9 cases of cast constriction, underwent intracardiac surgery from January 1999 to June 2003. Simple resection of stenosis membrane was performed in 12 cases, simple resection of stenosis membrane plus resection of myocardium of left ventricle outflow tract in 9 cases, simple resection of stenosis membrane plus resection of myocardium of left ventricle outflow tract plus treatment of united cardiac monstrosity in 16 case. Results No operative death and complications were found in all patients. Disappearance of cardiac murmur was found in 15 cases and diminishment of cardiac murmur in the rest of the patients after operation. A follow up time for 6 months to 2 years revealed that there were no obvious clinical symptoms, and the surgical outcomes were satisfactory. The cardiac ultrasound suggested that the left ventricular outflow tract was fluent without recurrent constriction. Conclusion Early treatment of congenital subaortic stenosis should be conducted when the disease was diagnosed. Better knowledge of pathological anatomy, proper operation, and prevention of complications are essential.

Objective To approach the expressions and the roles of connective tissue growth factor (CTGF) and membrane type 1 matrix metalloproteinases (MT1-MMP) in valve disease with pressure overload which induces extracellular matrix remodeling of left ventricle. MethodsOf 32 patients, 16 cases were pressure overload group (PO), who had the multiple valve disease with predominately aortic valve stenosis, having a ring diameter of aorta valve less than 1.3 cm, cross valve pressure gradient equal or more than 40 mmHg, and valvular regurgitation less than 4.0 cm2; The other 16 cases, as mitral stenosis group (MS), were simple mitral stenosis patients with single valve replacement. Meanwhile, 5 normal individuals served as control, who died from accident. Echocardiography was used to analyze the left ventricular function and detect the hypertrophic level of the left ventricle. Left ventricle muscle samples were obtained during operation. Histological features were studied by Masson staining, and collagenous contents were quantitated with a computer-assisted imaging analysis system. The mRNA expressions of CTGF and MT1-MMP were detected with RT-PCR. ResultsConcentric hypertrophy was observed significant in PO group, but myocardial hypertrophy was not found in MS group. Compare to the MS group and control, PO group had significantly more collagenous contents in left ventricle, thickened vessel wall, and narrow lumen of blood vessel (P0.05), but CTGF mRNA expression was increased in MS group compare to control (P

Objective To investigate the change of gene rstn expression in brain tissues following traumatic brain injury (TBI). Methods A total 90 SD rats were involved in the study and divided into normal control group (5 rats), sham operation group (10 rats), mild, moderate and severe trauma groups (25 rats per group). Rat model was made with sap pressure clash method and RT-PCR assay was employed to detect expression change of gene rstn at 3, 6, 24, 72 h and 1, 2, 4 weeks after TBI. The change of peripheral blood glucose concentration was measured in moderate trauma group to observe its relationship with gene rstn expression in brain tissue. Results Postoperative expression of gene rstn was increased in severe trauma group at 24 hours, in moderate trauma group at 72 hours and in mild trauma group at four weeks (P<0.05). The expression of gene rstn was increased in hippocampus, thalamus and cortex of all trauma groups at four weeks postoperatively, when the hippocampus showed the highest expression while the thalamus showed the least (P< 0.05). Moreover, the expression of gene rstn showed high level in injury side but low level in contralateral side in different districts (P < 0.05). The expression of gene rstn was increased the most obviously in severe trauma group (P <0.05). Peripheral blood glucose concentration showed a linearity positive correlation with gene rstn expression in brain tissue (R=5.32,P<0.05). Conclusions Expression of gene rstn shows obvious increase after TBI, and the time course correlates with the injury severity. The gene rstn expresses the most in the ipsilateral hippocampus. There shows a certain correlation between gene rstn expression and peripheral blood glucose concentration in brain tissues after TBI.
