穴位综合疗法对先天愚型患者智商的影响

【目的】评价中医穴位疗法对先天愚型患者智商的影响。【方法】将80例先天愚型患者随机分为穴位综合疗法治疗组(简称综合治疗组)、脑复康对照组(简称脑复康组)、空白对照组,综合治疗组取四神针(百会穴前、后、左、右各旁开1.5寸)、智三针(神庭穴和左右本神穴)、颞三针(耳失直上2寸为第1针,左右旁开1寸为第2、3针)、脑三针(脑户穴及两侧脑空穴)为主穴,进行针刺和维生素B_(12)、维丁胶性钙、脑活素穴位注射,脑复康组口服脑复康,空白组不作任何特殊治疗;4个月为1个疗程,期间嘱家长在家对患儿进行相应的教育和训练;治疗前和疗程结束后采用 《中国修订韦氏儿童智力量表》测定患儿的智商(IQ),包括语言IQ(VIQ)、操作IQ(PIQ)和总IQ(FIQ)。【结果】4个月治疗后,综合治疗组总体智力水平均有提高(与空白组比较,均P<0.01),并较脑复康组为优;并且综合治疗组治疗后IQ的提高主要为PIO各项得分的提高所贡献,与操作有关的几个项目的得分与治疗前比,均有显著意义(P<0.05),而VIQ得分治疗后未见显著性提高(均P>0.05)。【结论】穴位综合疗法能提高先天愚型患者的智商。

Randomized clinical trial of ascorbic acid in the treatment of pressure ulcers

The objective of this study was to assess the effects of ascorbic acid supplementation, 500 mg twice daily in the treatment of pressure ulcers as an adjunct to standardized treatment.

The design consisted of a multicenter blinded randomized trial. The control group received 10 mg of ascorbic acid twice daily.

Patients from 11 nursing homes and 1 hospital participated.

Main outcome measures included wound survival, healing rates of wound surfaces, and clinimetric changes over 12 weeks.

Eighty-eight patients were randomized. Intention-to-treat analysis showed that the wound closure probability per unit time (i.e., the closure rate) was not higher in the intervention group than in the control group (Cox hazard ratio of 0.78 [90% precision interval, 0.44–1.39]). Mean absolute healing rates were 0.21 and 0.27 cm²/week in the intervention and control group, respectively (PI of the adjusted difference: −0.17 to 0.13). Relative healing rates and healing velocities did not show favorable results of ascorbic acid supplementation, either. A panel scored slides of the ulcers with a report mark between 1 (bad) and 10 (excellent). The improvement was 0.45 and 0.72 points per week in the intervention and control group, respectively (PI of the adjusted difference: −0.50 to 0.20). With another clinimetric index we could not show any differences, either.

These data do not support the idea that ascorbic acid supplementation (500 vs. 10 mg twice daily) speeds up the healing of pressure ulcers.

Demonstration of synergistic effects of hyperthermia and photodynamic therapy using the chick chorioallantoic membrane model.

The chick chorioallantoic membrane (CAM) model was used to study vascular effects of photodynamic therapy (PDT) and hyperthermia (HPT) and the synergism of these modalities. The CAM is a convenient medium for monitoring the modifications of the vasculature. It is possible to view the CAM and to examine structural changes of individual blood vessels in real time. Moreover, the CAM is a closed system which lends itself to mathematical modeling of the temporal and spatial temperature profile and in which HPT can be performed quantitatively and to a selected depth, using different lasers. A porphyrin-type photosensitizer solution was applied to areas of the CAM, defined by teflon O-rings placed on the surface. Uptake dynamics of the sensitizer into the CAM was determined by analyzing its fluorescence in vivo. The CAM area was irradiated with a dual-wavelength laser system composed of a dye laser at 644 nm (to induce PDT) and a CO2 laser at 10.6 microns (to bring about HPT). Damage to the CAM vasculature, due to combined PDT+HPT, was compared to the outcome of the separate modalities, and a synergistic effect of about 40% was observed.
