目的脊柱推拿是传统医学的治疗方法之一。根据中医学脏腑经络相关理论,观察颈部脊柱推拿对自主神经系统功能的调节作用。方法选择成年健康男性志愿者,通过对受试者颈部进行推拿操作,包括触压双侧颈椎横突(C2-5水平)、左右旋转和扳法,以心率和心率变异性的改变为指标,观察推拿前后自主神经系统紧张性的改变。结果对30名正常成年男性志愿者的观察结果表明,推拿后心率显著降低(R-R间期延长);时域分析中SDNN显著性增加,频域分析中总功率谱显著性增加。以上结果皆提示迷走性张力增高。结论颈部脊柱推拿可调节自主神经系统张力,提示了针灸推拿方法治疗临床心血管疾病如心律失常的可能性。

研究了小麦麸质(Wheat Gluten,WG)在不同的模压温度、压力及不同的模压时间下模压成型样品的力学性能和耐水性,根据模压工艺对小麦麸质热压材料的力学性能和耐水性的影响,得到了小麦麸质理想的模压成型工艺条件为140℃下6.5 MPa,5 min+10.0 MPa,15 min。小麦麸质热压材料的拉伸强度为64 MPa,弯曲强度为82 MPa。对小麦麸质模压板的电性能研究表明,干态下其介电性能随电场频率增加而下降,但变化小;湿态下其介电性能明显提高,且随频率增加迅速下降,超过104Hz后区域变化趋于稳定;热压小麦麸质材料的电阻率随频率的增加呈直线下降;小麦麸质热压材料的电性能主要决定于材料结构的密实程度。

PURPOSE. To assess systemic and ocular vascular reactivity in response to warm and cold provocation in untreated patients with primary open-angle glaucoma an d normal control subjects. METHODS. Twenty-four patients with primary openangle glaucoma and 22 normal control subjects were subjected to a modified cold press or test involving immersion of the right hand in 40°C warm water followed by 4 °C cold water exposure, and finger and ocular blood flow were assessed by means of peripheral laser Doppler flowmetry and retinal flowmetry, respectively. Fing er and body temperature as well as intraocular pressure, systemic blood pressure , systemic pulse pressure, heart rate, and ocular perfusion pressure were also m onitored. RESULTS. The patients with glaucoma demonstrated an increase in diasto lic blood pressure (P=0.023), heart rate (P=0.010), and mean ocular perfusion pr essure (P=0.039) during immersion of the tested hand in 40°C water. During cold provocation, the patients demonstrated a significant decrease in finger (P=0.00 03) and ocular blood flow (the parameter velocity measured at the temporal neuro retinal rim area; P=0.021). Normal subjects did not demonstrate any blood flow o r finger temperature changes during immersion of the tested hand in 40°C water (P >0.05); however, they exhibited increases in systolic blood pressure (P=0.034 ) and pulse pressure (P= 0.0009) and a decrease in finger blood flow (P=0.0001) during cold provocation. In normal subjects, the ocular blood flow was unchanged during high and low temperature challenge. CONCLUSIONS. Cold provocation elicit s a different blood pressure, and ocular blood flow response in patients with pr imary open-angle glaucoma compared with control subjects. These findings sugges t a systemic autonomic failure and ocular vascular dysregulation in POAG patient s.

Aim: To investigate the relation between change in systemic blood pressures an d change in intraocular pressure. Methods: This was a population based study of people 43-86 years old living in Beaver Dam, Wisconsin. Measurements at baselin e (1988-90) and 5 year follow up of systemic blood pressures, intraocular press ures, and history of use of blood pressure medications. Results: Intraocular pre ssures were significantly correlated with systolic and diastolic blood pressures at both baseline and follow up. There were significant direct correlations betw een changes in systemic blood pressures and changes in intraocular pressure. The re was a 0.21 (95%CI: 0.16 to 0.27) mm Hg increase in IOP for a 10 mm Hg increa se in systolic and 0.43 (0.35 to 0.52) mm Hg increase in IOP for a 10 mm Hg incr ease in diastolic blood pressure. Further adjustment for diabetes and medication use did not alter these associations. Decreased systolic or diastolic blood pre ssures of more than 10 mm Hg over 5 years were significantly associated with dec reased IOP. Conclusions: Reduced systemic blood pressure is associated with redu ced intraocular pressure. T5his finding should be evaluated in other studies, es pecially with respect to the possibility of resultant decreased risk of open ang le glaucoma.
