以压迫阻滞针效定位的方法测试人体体表心包经的循行路线

以心功能和心电图为指标,以机械压迫阻滞针效为手段,比较压迫心包经穴位、经线上非穴位点和该穴点两侧对照点对针刺内关穴针效的影响,检测心包经在体表的循行轨迹。结果,压迫经上穴点针后各项指标变化微小,针效显著降低;压迫两侧对照点则对针效无明显影响。两者比较,差异非常显著。证明上肢屈侧确有一条与心包经一致的机能路线,并与心脏机能活动调节密切相关。     

麦饭石对骨折愈合过程影响的实验研究

提要从生物力学及组织学角度观察了麦饭石对骨折愈合过程的影响。强度测试结果表明:用药组的拉伸、弯曲破坏载荷及拉伸、弯曲强度均比对照组高(P<0.05～0.01)。病理报告提示:用药组与对照组比较断端血肿吸收快,同一期内肉芽组织转变为骨样组织多,连接快,软骨骨化少,骨改建早。表明麦饭石不仅能提高骨折愈合质量,而且加快了骨折愈合速度,是促进骨折愈合的有效药物。     

EFFECTS OF SDS, PBS SOLUTIONS UPON FLUORESCENCE VALUES OF DERMATOPHA GOIDES PTERRONYSSINUS RADIOALLERGOSORBENT TEST INHIBITION

Objective To explore the effects of SDS, PBS re-dissolvent solutions on fluorescence values of radioallergosorbent test (RAST) inhibition. Methods Dermatophagoides pterronyssinus allergen immunoCAP and UniCAP 100 System were used. The Sera Pool consisted of 20 Dermatophagoides pterronyssinus allergic patients sera, their specific IgE fluorescence values were between 12 505 and 24 776. Results Fluorescence value percentages decreased: 62.9%, 54.1%, 43.5%, 6.7%, 3.7%, 2.6%, 2.2%, and 1.4% respectively, when SDS concentrations were at 2%, 1%, 0.5%, 0.25%, 0.1%, 0.05%, 0.025%, and 0.01%. Fluorescence values decreased more than 5% with SDS concentrations equal to 0.25% or higher. PBS in 0. l and 0.01 mol/L concentrations decreased fluorescence values 2.9% and 0.9% respectively. Conclusions SDS is a commonly used surfactants in allergen extract and re-dissolvent prepared allergen precipitation for RAST inhibition. Thus effects of surfactants (e.g. SDS) upon the RAST inhibition tests must be considered when they were used as re-dissolvent agents to improve protein resolution in RAST inhibition.

The Adverse Health Effects of Oil Spills: A Review of the Literature and a Framework for Medically Evaluating Exposed Individuals

Abstract

In April 2010, an explosion on an oil rig in the Gulf of Mexico killed 11 workers, injured 17 workers, and spilled an estimated 185 million gallons of crude oil into the Gulf. Adverse effects on the health of cleanup workers, fishermen, and others as well as on the ecosystem are being studied. This paper reviews published studies of the adverse health effects due to previous oil spills. Acute effects have included: respiratory, eye, and skin symptoms; headache; nausea; dizziness; and tiredness or fatigue. Chronic effects have included: psychological disorders, respiratory disorders, genotoxic effects, and endocrine abnormalities. We also present a systematic approach to evaluating individuals exposed to oil spills.

Evaluating Atypical Features of Femur Fractures: How Change in Radiological Criteria Influenced Incidence and Demography of Atypical Femur Fractures in a Community Setting

Identification of atypical femoral fractures (AFFs) can be challenging. To assist in the radiological assessment, an American Society for Bone and Mineral Research (ASBMR) Task Force developed a case definition for AFFs in 2010, revising it in 2013. How the revised definition performs in a community setting compared with the 2010 definition is unknown. We applied the 2013 criteria to 372 femoral fractures that occurred between January 1, 1996, and June 30, 2009, employing two independent expert physician reviewers. We used radiographs that had been categorized in a previous study on the incidence of atypical fractures using 2010 ASMBR criteria (BEAK1). In this follow‐up study (BEAK2), the same reviewers reviewed all previously identified femoral shaft fractures (FSFs) (n = 197) and distal femur fractures (n = 131) plus a 15% random sample of intertrochanteric fractures (n = 49). After initial review, agreement between the two reviewers ranged from 63% to 100% for specific features, and 84% of radiographs received the same overall classification. Fewer fractures met the 2013 compared with 2010 ASMBR case definition of AFFs (37 per 2013 criteria versus 74 per 2010 criteria). Forty‐three radiographs (58%) categorized as AFFs according to 2010 criteria were no longer AFFs when 2013 criteria were applied, and an additional 12 non‐atypical FSFs according to 2010 criteria were reclassified as AFFs according to 2013 criteria. The major cause of AFF reclassification was the change in the definition of transverse configuration. The modification of the comminution, non‐traumatic, and periosteal/endosteal thickness criteria resulted in the reclassification of non‐atypical FSFs to AFFs. Incidence rate of AFFs according to 2013 ASBMR criteria was lower overall during the 13 years of observation than when the 2010 ASBMR criteria were applied, although we saw a slight increase starting in 2000. As in BEAK1, we found that those with AFFs were younger, more often female, and had a higher exposure rate to bisphosphonates than those with non‐atypical FSFs. As we continue to unravel the demographics of those who suffer from AFFs, our study adds information about how the change in criteria influences epidemiological work. © 2017 American Society for Bone and Mineral Research.     

Long-lasting cognitive,physiological and hematological effects in rehabilitated,early dietary iron-deficiency adult rats,and improvement by treatment with a mixture of essential fatty acids

Abstract

Despite some successful interventions and the large research efforts on this topic, iron deficiency and anemia remain the most common nutritional disorders in the world today. Recently, several researchers indicated that early, induced, iron deficiency produced a long-lasting effect even if the hemoglobin and iron levels returned to normal values. Recent human studies showed that 10–12-year-old children, who were iron deficient at age 1 year, showed lower IQ scores. In this study, we tried to imitate this condition by inducing iron deficiency in rats at age 21 days, for 28 days, and then tested the rats on day 120. The former iron-deficient rats had normal hematological and motor activity values, and normal thermoregulatory response, but they were very slow learners compared to the control rats. Treatment with a mixture of essential fatty acids improved their learning capacity.
