Objective To investigate the improving effects of Shenshao decoction on myocardial structure and function in diabetic cardiomyopathy,and its effect on expression of TLR4/MyD88-dependent pathway signal in diabetic cardiomyopathy.Methods Diabetes mellitus was induced in 8-week-old male Wistar rats by a single intraperitoneal injection of streptozotocin.The changes of plasma myocardial enzyme (CK, LDH) and high sensitive C reactive protein (hsCRP) were measured.Cardiac function was measured by left ventricular intubation.Hematoxylin and eosin staining and electron microscopy were used to observe the changes of myocardial morphology and ultrastructure in rats.Expression of Toll-like receptor 4(TLR4), myeloid differentiation protein 88(MyD88), and nuclear factor-κB P65(NF-κB P65) were tested by immunohistochemistry.Results After 6 weeks of treatment, the left ventricular diastolic and systolic functions were obviously improved;the degrees of myocardial fibers and mitochondrial damage were obviously relieved;the content of CK, LDH and hsCRP decreased (P< 0.05), and hsCPR was positively correlated with CK and LDH (r=0.823,r=0.819,P < 0.05).The expressions of TLR4, MyD88, NF-κB P65 were significantly decreased (P< 0.05).There was no significant difference in the above mentioned indicators between the control group and control+Shenshao decoction group (P> 0.05).Conclusions Shenshao decoction can reduce the myocardial injury in diabetic cardiomyopathy and improve cardiac diastolic and systolic functions.The mechanism may be related to attenuated inflammation by TLR4/MyD88 dependent signaling pathway.

Objective:To study the physical activity level and its influence factors among residents in one suburb of Beijing,so as to provide specific interventions for different people in different circum-stances and to provide reference for health relevant policy-making in the future.Methods:In the study, 7 31 9 subjects aged 1 8 years or above were involved.The self-designed questionnaires based on Health Belief Model (HBM)had acceptable validity and reliability.The physical activity levels were calculated to classify sufficient or insufficient amount by a thousand-step equivalent greater than or equal to 6 or 1 0. Multiple variable Logistic regression was used to explore the influence factors of the physical activity among the residents.Results:The residents’median amount of physical activity in the suburb district of Beijing were 9.1 thousand-step equivalent with quartile of (3.8,20.4).The percentages of the thou-sand-step equivalent greater than or equal to 6 or 1 0 were 63.7% and 47.7%,respectively.The median amounts of physical activity from work or household chores,transportation and recreation physical activi-ties were 4.0,1 .0,0.0 and the components of the total amount of physical activity from those were 61 .7%,1 8.3% and 20.1 %,respectively.There were 8.6% residents whose life did notinvolve moder-ate or vigorous intensity activities.By using factor analysis,five factors were extracted from the scale based on the HBM;These factors together contributed to 63.7% of the sum of the squared loadings.The differences of physical activity levels on education level,age,gender,self-efficacy,cues,subjective and objective barriers were statistically significant (P <0.05).Those who were female,with older age,lower education level,higher self-efficacy,fewer cues,fewer subjective and objective barriers preferred to do more physical activities.Conclusion:The physical activity levels among the residents in the suburb dis-trict of Beijing are moderate and high,and most amount of physical activities from work or household chores.Those who are male and whose ages are from 1 8 to 29 years and whose education levels are of university or above should be focused on intervention.Specific interventions should be developed for dif-ferent people in different situations;More attention should be paid to improve the residents’self-efficacy and reduce the subjective and objective barriers of physical activity,and we also should actively advocate people to have more leisure exercise so as to improve the physical activity level among all residents.

In China, the treatment of AIDS With Chinese herbal medicine compound has been widely studied and practiced. Clinical Studies showed that the treatment of AIDS with Chinese medicine can significantly relieve AIDS patients' clinical symptoms, improve life quality with rising immunity and alleviate toxic and side effects in antiviral drug. This study took 28 Clinical Studies on the treatment of AIDS with Chinese herbal medicine compound published in Chinese periodicals as the research object, and designed Tree Analysis Algorithm was used to analyze prescription compatibility in the treatment of AIDS with Chinese herbal medicine compound. Results of data analysis revealed that clinical therapy on AIDS could be classified into three types: predominent de-toxication, predominent supplementing Qi, and simultaneous de-toxication and supplementing Qi due to different understanding the pathogenesis of excessive evil and deficient essence-qi. But in practical medication, there has not formed a reasonable and effective combination or basic prescription up to now, except that Astragalus was wildly used.
