Needle Sensation and Personality Factors Influence Therapeutic Effect of Acupuncture for Treating Bell's Palsy: A Secondary Analysis of a Multicenter Randomized Controlled Trial / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>It has not been solved what kind of needle sensation might influence outcomes of acupuncture treatment. Effects of personality factors on the therapeutic effect of acupuncture have not been investigated. This study aimed to find the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell's palsy.</p><p><b>METHODS</b>We performed a secondary analysis of a prospective multicenter randomized controlled trial of acupuncture for Bell's palsy. Patients were randomly assigned to the de qi and control groups, respectively. The primary outcome was facial nerve function at month 6. The intensity of each needle sensation was rated by a visual analog scale. Psychosocial factors were assessed by the pretreatment mediator questionnaire; 16 Personality Factor Questionnaire (16PF) was used for assessing personality factors and digit cancellation test for assessing attention.</p><p><b>RESULTS</b>After 6 months, patients in the de qi group had better facial function (adjusted odds ratio [OR]: 4.16, 95% confidence interval [CI]: 2.23-7.78). Path analysis showed that intensity of needle sensation of fullness had direct effect on House-Brackmann (HB) score at month 6. In de qi group, the low HB score on day 1 (OR: 0.13, 95% CI: 0.03-0.45) and the low Social Boldness score (OR: 0.63, 95% CI: 0.41-0.97) in 16PF were associated with better facial function. In control group, low HB score on day 1 (OR: 0.25, 95% CI: 0.13-0.50), low Vigilance score (OR: 0.66, 95% CI: 0.50-0.88), and high Tension score (OR: 1.41, 95% CI: 1.12-1.77) in 16PF were related to better facial function.</p><p><b>CONCLUSIONS</b>The needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment. Both of them should be considered seriously in acupuncture treatment and research.</p>

Time-series analysis on relationship between air pollution and mortality from circulatory system diseases among registered residents in Chaoyang district of Beijing / 中华预防医学杂志

<p><b>OBJECTIVE</b>This study aims to investigate relationship between daily concentration of PM(10), SO(2), NO(2) and daily mortality due to circulatory system diseases in Chaoyang district, Beijing.</p><p><b>METHODS</b>The time-series data of daily mortality from circulatory system diseases of registered residents in Chaoyang were obtained from Chaoyang District Center for Disease Control and Prevention. The daily concentration of sulfur dioxide (SO(2)), nitrogen dioxide (NO(2)), and particulate matter (PM(10)) were collected from Beijing Municipal Environmental Monitoring Center. And the routine monitoring meteorological data were collected from Beijing Meteorological Bureau, including daily mean temperature and daily mean relative humidity. The time-series analysis was then conducted to determine the relationship of mortality from circulatory system diseases with daily concentrations of SO(2), NO(2) and PM(10) by using Poisson regression with generalized additive model (GAM).</p><p><b>RESULTS</b>During January 2004 to September 2008, the cumulative death number from circulatory system diseases of registered residents in Chaoyang district of Beijing was 19 241, the daily average concentration of SO(2), NO(2), PM(10) was 48.7, 63.9, 146.1 µg/m(3), respectively. The single pollutant model showed an increase of daily concentration of PM(10), SO(2) and NO(2) by 10 µg/m(3) will augment the mortality from circulatory system diseases by 0.20% (95%CI: 0.01% - 0.39%), 0.36% (95%CI: -0.13% - 0.85%) and 0.30% (95%CI: -0.34% - 0.94%), respectively. In the multiple air pollutants models, combinatorial effects of PM(10) and SO(2) still positively correlated with increased mortality from circulatory system diseases (P < 0.05), whereas changes of the concentration of NO(2) had no significant effect on mortality from circulatory system diseases (P > 0.05).</p><p><b>CONCLUSION</b>Our findings in this study elucidated that changes of the concentration of PM(10) and SO(2) had a positive correlation with daily mortality from circulatory system diseases among the local residents in Chaoyang District, whereas the daily concentration of NO(2) was irrelevant with that.</p>

Effects of cell cycle inhibitor on astroglial proliferation and scar formation and neuroprotection after focal cerebral ischemia in rats / 中华神经科杂志

Objective To observe the effects of cell cycle inhibitor on astrocytic proliferation and scar formation and to study neuronal apoptosis after focal cerebral ischemia in rats.Methods Ischemic model was established by photochemistry method.T_2-weighted MRI was performed on the 3rd, 7th, and 30th day after focal cerebral ischemia.The expression of glial fibrillary acidic protein(GFAP)and apoptosis was observed by immunofluorescence.The protein levels of GFAP and proliferation cell nuclear antigen (PCNA), CyelinA and CyclinB1 were measured by Western blotting from the ischemic and sham animals finished on the 3rd, 7th, and 30th day.Results A marked and significant reduction of brain infarction volume was found in Olomoucine-treated ischemic animals(2.27%?0.28% , 1.87%?0.19%, 1.08%? 0.18%)as compared with controls(5.10%?0.35%, 4.60%?0.26%, 3.96%?0.28%, P
