Aim To explore the best way of calculating antihypertensive effect of nifedipine GITS on trough to peak ratio (T/PR), and smoothness index (SI) of the drug from ambulatory blood pressure monitoring (ABPM). Methods 32 cases of mild to moderate essential hypertension patients were enrolled and each was given 30 mg of nifedipine GITS once daily. ABPM was repeated for four weeks. ABPM data were analyzed statistically and T/PR calculated by both individual and whole group way. Results The casual blood pressure(CBP) and ABP were lowered by (24?12)/(12?8) mmHg and ( 14.5 ? 3.9 )/( 11.2 ? 3.0) mmHg .The T/PR by individual way was 0.65 ? 0.23 for SBP and 0.66 ? 0.25 for DBP, while by whole group way 0.62 for SBP and 0.68 for DBP. The smoothness index (SI), a new method for assessing the homogeneity of 24 hour blood pressure reduction by antihypertensive therapy, was 3.74 for SBP and 3.77 for DBP after treatment. Conclusion Nifedipine GITS lowers blood pressure effectively and smoothly for 24 hours long. Antihypertensive effects can be reflected by T/PR and SI.

BACKGROUND:Studies have shown that low-intensity and short-time vibration with a certain frequency can reduce the absorption of bone tissue and increase the quantity and quality of bone through promoting the proliferation and differentiation of osteoblasts.
OBJECTIVE:To investigate the effects of different frequencies of vibration strains on cycle, proliferation and differentiation potency of RAW264.7 cel s cultured in vitro.
METHODS:Passage 6 RAW264.7 cel s in good conditions were randomly divided into six groups, and each group was induced cultured with Dulbecco’s modified Eagle’s medium containing receptor activator of nuclear factor kappa B ligand. The final concentration of receptor activator of nuclear factor kappa B ligand was adjusted to 50μg/L, and then kept without changes. The non-loading group did not loaded with vibration strain, and the other five groups were loaded with 3-10 Hz, 15-35 Hz, 35-45 Hz, 50-70 Hz and 70-90 Hz vibration strains on the RAW264.7 cel s respectively. The other vibration parameters were consistent;the vibration time was 15 min/time with the vibration intensity of 0.3 g, twice per day. The cel cycle and cel proliferation were detected at 3 and 6 days after loading of vibration strains.
RESULTS AND CONCLUSION:After composite vibration loading for 6 days, the cel cycle phase in the vibration groups was changed to some extent when compared with the non-loading group. Compared with non-loading group, the cel number in the G 1 phase of the vibration group was significantly increased (P<0.01);the cel number in the S phase and G 2+M phase of the vibration group was significantly decreased (P<0.01);the vibration parameters in the vibration group were significantly decreased (P<0.01). The results indicate that different frequencies of vibration strains can affect the cel cycle and proliferation, and can inhibit the proliferation and differentiation of osteoblasts.

This experimental study was designed to unravel the relationship between muscle tension and its electrophysiological property. The experiments on repetitive pulse stimulus in different current intensity to rabbit's motor nerve were performed in different pulse frequency by electromyography which applied electrical pulses and excited the tibial nerve, and by Instron 5544 machine which measured muscle tensions. The experimental data revealed that the tension force varied with the stimulus frequency in a quasi-parabolic relation, while it seemingly increased little with the stimulus intensity.

Objective:
To understand the status of physical health education in primary schools in Ganjiang New District, and to provide a reference for physical health education for educational managers.
Methods:
Based on the client satisfaction index and national documents, satisfaction questionnaire survey was administered among parents of 789 primary school students from 5 school in Ganjiang New Area.Sixteen indicators including physical monitoring and hours of physical education.
Results:
Modrate satisfaction level towards physical health education found among parents ranging from "4" to "3". The highest score for "sports teacher level" was 4.13 and the lowest score for "multimedia education" was 3.00. The average value of "sports teacher training locations" was 4.08, which was higher than the "overall satisfaction" score of 3.67; the average value of "school sports activities" was 3.58, which was lower than "overall satisfaction". The five-dimensional sample has good independence and there was no multicollinearity; the coefficient of influence of "Physical health of students" was 0.15(P<0.05).
Conclusion
Parents satisfaction with the management of physical health education in the five primary schools is generally good, but they are dissatisfied with the lack of physical education teachers venues and teaching hours. It is recommended that parents correct the "five education concept" to improve health education, balance the strengths and weaknesses of school education to make up for shortcomings, and strengthen the home school society co-education mechanism to improve the physical health of primary school students in Ganjiang New District.
