Effectiveness evaluation of health belief model-based health education intervention for patients with hypertension in community settings / 中华预防医学杂志

To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (0.016), and perceived seriousness was decreased by 0.73 (0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, 0.001) and diastolic blood pressure was decreased by 4.07 mmHg (0.014), respectively. The β (95) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (0.05). Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.

Influential factors of leisure exercise among patients with type 2 diabetes mellitus based on the planned behavior theory / 中华疾病控制杂志

Objective This study applied the theory of planned behavior to investigate the leisure exercise situation among patients with type 2 diabetes mellitus (T2DM) and its influencing factors. Methods The questionnaire was self-designed based on the theory of planned behavior, which had good reliability and validity. Structural equation modeling was used to estimate the determinants of leisure exercise and the potential intermediate effect. Results 774 patients with T2DM were enrolled in this study. 52.6% were over 60 years old. The median amount of leisure exercise was 0.0 thousand-step equivalent with quartile of (0.0, 2.0). Structural equation modeling showed that the effects of attitude (β=0.080) and intention (β=0.277) on leisure exercise were significant. Besides, perceived behavioral control (β=0.180) had an indirect effect on exercise through intention. Conclusions In general, most patients with type 2 diabetes have insufficient amount of exercise. Improving attitude, control and intention to exercise would be one crucial part of exercise health education among patients with T2DM.

Differential temporal neural responses of pain-related regions by acupuncture at acupoint ST36: a magnetoencephalography study / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Previous neuroimaging studies primarily focused on the spatial distribution of acupuncture needling stimulation. However, a salient feature of acupuncture was its long-lasting effect. This study attempted to detect the spatial-temporal neural responses evoked by acupuncture at an analgesia acupoint ST36 by using magnetoencephalography. To further verify its functional specificity, we also adopted acupuncture at Pericardium 6 and nonacupoint as separated controls.</p><p><b>METHODS</b>Forty-two college students, all right-handed and acupuncture naïve, participated in this study. Every participant received only one acupoint stimulation, resulting in 14 subjects in one group. Both magnetoencephalography data (151-channel whole-head system) and structural functional magnetic resonance imaging data (3D sequence with a voxel size of 1 mm(3) for anatomical localization) were collected for each subject. All processing procedures were performed in BrainStorm Toolbox.</p><p><b>RESULTS</b>Acupuncture at ST36 showed a significantly time-varied brain activities with different onset time. Our results presented that acupuncture at different acupoints (or comparing with nonacupoint) can specifically induce neural responses in different brain areas-acupuncture at ST36 can specifically induce the neural responses of pain-inhibition areas, while acupuncture at PC6 can specifically induce the activities of the insula and amygdala.</p><p><b>CONCLUSIONS</b>In the present study, we attempted to detect the temporal neural responses underlying the functional specificity of acupuncture at ST36, using acupoint belonging to different meridians and non-acupoint with efficacy-irreverent as separate controls. The specific neural substrates involving acupuncture at different acupoints may be related to its functional specificity in clinical settings.</p>

Effect of estrogen replacement therapy on respiratory of ovariectomized rats / 中国康复理论与实践

@#ObjectiveTo observe effect of estradiol on respiratory of ovariectomized rats.Methods30 adult female rats were randomly divided into ovariectomy group (group A), estradiol group (group B) and sham ovariectomy group (group C). Rats of group B were injected with 17-β estradiol (20μg/kg/d), that of group A and group C were injected only with normal saline (0.1ml/d). After 6 weeks, effect of estradiol on respiratory of ovariectomized rats was assessed with testing level of rats' serum estradiol and discharge frequency and integrated amplitude of phrenic nerve. ResultsThe level of serum estradiol of group A was significantly decreased compared with group B and group C (P<0.01). Discharge frequency and integrated amplitude of phrenic nerve of group A were decreased compared with group B and group C (P<0.05).ConclusionEstradiol can excite respiratory responses in ovariectomized rats.
