Objective Studying the related factors of left ventricular hypertrophy for hypertensive disease, to provide the basis for clinical treatment. HZ Methods 500 hypertensive disease patients were performed dynamic monitoring of blood pressure and UCG. Then 130 patients with left ventricular hypertrophy were compared the dynamic blood pressure, age, sex and diseases course with 130 patients who had not left ventricular hypertrophy. Results (1) Systolic pressure, the load and the night descent rate of systolic pressure were significantly related to left ventricular hypertrophy, there was obviously difference in two groups. To the patients with systolic pressure and diastolic pressure were all increased, the incidence rate of left ventricular hypertrophy was reduced. (2) The age of left ventricular hypertrophy group was higher than no left ventricular hypertrophy group. (3) The female's incidence rate of hypertensive disease in left ventricular hypertrophy group was higher than no left ventricular hypertrophy group. (4) The course of diseases in left ventricular hypertrophy group was extended than no left ventricular hypertrophy group. The incidence rate of left ventricular hypertrophy was obviously higher in the patients whose blood pressure was increased in the daytime. Conclusion (1) The pulse pressure is a important forecast factor in numerous risk factor. (2) The advanced age is a risk factor to hypertensive disease. (3) The female hypertensive disease patients take place left ventricular hypertrophy is easier than the male. (4) Left ventricular hypertrophy is significantly related to hypertensive disease course, and isn't significantly related to blood pressure's durative. The clinic must think highly of observing and evaluating the pulse pressure, the long disease course of old female patients. There is important clinical significance to reinforce monitoring the risk factor of left ventricular hypertrophy, and to perform pertinent treatment and prevention for the high risk patients.

To investigate the effects of different surface conditioning methods on the shear bonding strength of glass-infiltrated ceramic to dentine, 24 glass-infiltrated ceramic testing-pieces were divided into four groups randomly. Among them 3 groups were treated with A(sandblasting+silance), B(etching+silace) or C(silance), separately, while group D was set as the control. Bonding the ceramic pieces to dentine with Super-Bond and the shear bonding strengths was measured. The results showed that the shear bonding strength of group D was lower than that of group A, B and C (P0.05). It is suggested that surface conditioning using combined sandblasting with silance can remarkbly improve the shear bonding strength of glass-infiltrated ceramic to dentine.
