耳穴电针治疗子宫内膜异位症痛经的随机对照研究

目的:观察耳穴电针治疗子宫内膜异位症(EMT)痛经的临床疗效,并探讨其部分作用机制。方法:将80例EMT痛经患者随机分为耳电针组和体电针组。耳电针组刺激耳穴子宫、皮质下、神门、内分泌等,体电针组刺激体穴天枢、气海、关元、三阴交、地机、子宫等,均每次留针30 min,隔天1次,10次为一疗程,每个疗程自月经干净后次日开始,共治疗3个疗程。分别于治疗前后进行痛经程度评分,并评定总体疗效,放射免疫法检测不同治疗阶段的血浆前列腺素E2(PGE2)、6-酮-前列腺素F1α(6-Keto-PGF1α)水平。结果:耳电针组痊愈2例,显效5例,有效30例,无效3例,总有效率为92.5%;体电针组痊愈1例,显效2例,有效31例,无效6例,总有效率为85.0%;两组总体疗效比较差异无统计学意义(P>0.05)。两组痛经程度评分治疗后均比治疗前降低(均P<0.01),治疗后第3次月经时,耳电针组评分低于体电针组(P<0.05)。两组治疗后第3次月经时与治疗后第1次月经时比较,血浆PGE2含量均下降(均P<0.01),血浆6-Keto-PGF1α含量均升高(均P<0.01);治疗后第3次月经时耳电针组与体电针组比较,血浆PGE2含量较低(P<0.05),血浆6-Keto-PGF1α含量较高(P<0.05)。结论:耳穴电针和体穴电针均可有效治疗EMT痛经,但耳穴电针比体穴电针具有更加持续的镇痛作用;抑制血浆PGE2分泌,减轻盆腔局部炎性反应,以及升高血浆6-Keto-PGF1α水平,抑制血管及子宫平滑肌痉挛性收缩,可能为耳穴电针和体穴电针治疗EMT痛经的部分作用机制。

The effect of cooling on toe systolic pressures in subjects with and without Raynaud's syndrome in the lower extremities

Summary. The effect of changes in local and body temperature on the toe systolic pressures was studied in 20 subjects with and 30 without Raynaud's syndrome in the toes. The pressures were significantly lower in the group with Raynaud's syndrome under all experimental conditions (P < 0·01). The pressures were significantly lower during body cooling than during body warming in both groups (P < 0·01). The mean decrease with body cooling was 58 mmHg in the group with Raynaud's syndrome and 24 mmHg in the control subjects (P < 0·01). During body cooling pressures fell to less than 30 mmHg in 70% of subjects with Raynaud's syndrome and in 3% of the controls. Local cooling from 30 to 10°C during body cooling resulted in a significant mean decrease in pressure of over 40 mmHg in both groups (P < 0·01) and the pressure fell below 30 mmHg in over 90% of the group with and in 26% of those without Raynaud's attacks. The results indicate the importance of body cooling and local temperature in the mechanism of vasospasm in the toes. They are also relevant to the diagnosis of Raynaud's syndrome in the lower limbs and have implications for the testing of patients with arteriosclerotic occlusion since erroneously low pressure values could be obtained in tests when the feet are cold.     

Self-perception and action in infancy

By 2–3 months, infants engage in exploration of their own body as it moves and acts in the environment. They babble and touch their own body, attracted and actively involved in investigating the rich intermodal redundancies, temporal contingencies, and spatial congruence of self-perception. Recent research is presented, which investigats the spatial and temporal determinants of self-perception and action infancy. This research shows that, in the course of the first weeks of life, infants develop an ability to detect intermodal invariants and regularities in their sensorimotor experience, which specify themselves as separate entities agent in the environment. Recent observations on the detection of intermodal invariants regarding self-produced leg movements and auditory feedback of sucking by young infants are reported. These observations demonstrate that, early in development and long before mirror self-recognition, infants develop a perceptual ability to specify themselves. It is tentatively proposed that young infants’ propensity to engage in self-perception and systematic exploration of the perceptual consequences of their own action plays an important role in the intermodal calibration of the body and is probably at the origin of an early sense of self: the ecological self.     

Associations between body morphology and bone mineral density in premenopausal women

To investigate whether body morphology, obesity and its long time evolution were associated with lumbar and femoral bone mineral density (BMD) in premenopausal women of the same age. Design: Cross-sectional study. Subjects: 72 healthy premenopausal women born in 1950 (42 years) with a regular physical activity. Measurements: BMD measured by dual-X-ray absorptiometry (DEXA) at lumbar spine and proximal femur; body weight, body mass index (BMI), BMI at 20 years (BMI-20), increase in BMI since age of 20 (BMI->20), body circumferences (breast, waist, hip) and their ratios (WHR, BHR, WBR), smoking and alcohol intake. Results: Lumbar spine BMD did not correlate with any anthropometric measurement. Femoral BMDs correlated positively with weight, BMI, BMI-20, breast, waist, WHR and BHR. The BMI-20 explained the 5% and the current BMI the 13% of variance of total femur BMD. After adjustment for weight or BMI, breast circumference and BHR remained significantly correlated with all femoral BMDs sites except neck. Weight was the best predictor for neck BMD (R² = 0.08; p < 0.02), and BHR for Ward's triangle (R² = 0.12; p < 0.01) and trochanter (R² = 0.10; p < 0.001). Alcohol intake, cigarette smoking, and age of menarche were not related to BMDs. Conclusion: In premenopausal women of the same age, lumbar spine BMD was not associated with any anthropometric measurement. Greater BHR and its long time of evolution may be determinants of greater femoral BMD (trabecular), whereas body weight may be determinant of femoral neck BMD (cortical). Further studies are needed to determine whether large breast to hip ratio may be considered as a protective factor for femoral osteoporosis.     

Sensori-motor Function in Older Persons with Diabetes

Twenty-five persons with diabetes (aged 55–83 years) who were living independently in the community, and 40 age- and sex-matched non-diabetic controls were assessed for tactile sensitivity, vibration sense, proprioception, quadriceps strength and body sway. In both men and women, those with diabetes performed significantly worse in tests of body sway on firm and compliant surfaces compared with the control subjects after controlling for weight and body mass index. The female diabetic subjects also performed significantly worse in tests of peripheral sensation and strength compared with controls. Age-related declines in sensori-motor function were greater in the diabetic group (r = 0.55–0.75) than in the controls (r < 0.44), while within the diabetic group, duration of diabetes and vibration sense were significantly correlated with sway on a compliant (foam rubber) surface with the eyes open (partial r = 0.52, p < 0.01 and r = 0.55, p < 0.01, respectively). The study findings provide evidence that older people with diabetes have problems with stability and related sensori-motor factors which may place them at increased risk of falls.
