[Objective] The present study was to evaluate the association of serum total cholesterol level and prognosis in patients with acute left heart failure and associated mechanisms.[Methods] Sixty-eight patients due to acute episode of left heart failure prospectively enrolled,and baseline data and biochemical parameters were collected.After discharge,patients were follow-up for 1 month and they were divided into two groups (with and without cardiovascular events).Differences between groups were evaluated and the association of serum total cholesterol level and cardiovascular events were analyzed by logistic regression analysis.[Results] The mean age was 57.3 ± 12.6 years old and 52 cases were male patients accounting for 76.5 ％.Among these patients,46 had a diagnosis of coronary heart disease (67.6 ％),10 rheumatic heart disease (14.7 ％),12 dilated cardiomyopathy (17.7％),38hypertension (55.9％) and 24 diabetes mellitus (35.3％).After 1 month's follow up,39 patients (57.4％) had experienced cardiovascular events,36 cases were re-hospitalized,and 3 died from heart failure.Compared to those with cardiovascular events,event free individuals were younger and were less likely smokers (P ＜ 0.05).In addition,event free group had lower serum levels of N-terminal pro-BNP and C-reactive protein (P ＜ 0.05) while serum levels of total cholesterol and albumin were significantly higher (P ＜ 0.05).There was no significant difference in medication between these two groups.After adjusted for age,gender,smoking,systolic blood pressure,serum albumin level,diabetes,hypertension and medications,increased total cholesterol level was independently associated with better prognosis with odds ratio of 0.91 (95 ％ confidence interval 0.80-0.96).Further adjusted for C-reactive protein,the association was attenuated to non-significance,with odds ratio of 0.97 (95 ％ confidence interval 0.87-1.09).[Conclusion] Adequate serum total cholesterol level was beneficial for improving short-term cardiovascular outcomes in patients with left heart failure and the potential mechanisms might be related to cholesterol effects on improving nutritional status and anti-inflammation.

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.

Objective To investigate the effectiveness and safety of fast-track surgery (FTS) application in gastric cancer operation.Methods A total of 196 cases of gastric cancer operation in our hospital from January 2012 to June 2016 were selected and divided into the FTS group and tradition group,98 cases in each group.The postoperative first time exhaust and defecation time,hospitalization stay length,hospital costs and postoperative complications were compared between the two groups.Results The postoperative first time exhaust and defecation time in the FTS group were earlier than those in the tradition group,the hospitalization duration was decreased and hospitalization costs were reduced,the differences between the two groups were statistically significant(P＜0.05).The occurrence rate of pulmonary complications had statistically significant difference between the two groups(P＜0.05).Digestive tract fistula,fatality rate,re-hosplitalization rate and occurrence rate of overall complications had no statistical difference between the two groups(P＞0.05).Conclusion The application of FTS in gastric cancer operation can promote more rapid recovery of gastrointestinal function,shortens hospitalization stay and reduces the hospitalization costs.

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.

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.

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.
